Abstract
OBJECTIVE Despite the within-group heterogeneity, Asian American (AA) and Native Hawaiian and Pacific Islander (NH/PI) patients are often grouped together. We compared the patterns of guideline-concordant care for locally advanced cervical cancer for disaggregated AA and NH/PI patients. METHODS Patients with stage II-IVA cervical cancer between 2004 and 2020 were identified from the National Cancer Database. AA patients were disaggregated as East Asian (EA), South Asian (SA), and Southeast Asian (SEA). NH/PI patients were classified as a distinct racial subgroup. The primary outcome was the proportion undergoing guideline-concordant care, defined by radiation therapy with concurrent chemotherapy, brachytherapy, and completion of treatment within eight weeks. RESULTS Of 48,116 patients, 2107 (4%) were AA and 171 (<1%) were NH/PI. Of the AA patients, 36% were SEA, 31% were EA, 12% were SA, and 21% could not be further disaggregated due to missing or unknown data. NH/PI patients were more likely to be diagnosed at an early age (53% NH/PI vs. 30% AA, p < 0.001) and have higher rates of comorbidities (18% NH/PI vs. 14% AA, p < 0.001). Within the AA subgroups, only 82% of SEA patients received concurrent chemotherapy compared to 91% of SA patients (p = 0.026). SA patients had the longest median OS (158 months) within the AA subgroups compared to SEA patients (113 months, p < 0.001). CONCLUSION Disparities exist in the receipt of standard of care treatment for cervical cancer by racial and ethnic subgroups. It is imperative to disaggregate race and ethnicity data to understand potential differences in care and tailor interventions to achieve health equity.

Abstract
There have been major advances in the armamentarium for hepatocellular carcinoma (HCC) since the last official update of the Barcelona Clinic Liver Cancer prognosis and treatment strategy published in 2018. Whilst there have been advances in all areas, we will focus on those that have led to a change in strategy and we will discuss why, despite being encouraging, data for select interventions are still too immature for them to be incorporated into an evidence-based model for clinicians and researchers. Finally, we describe the critical insight and expert knowledge that are required to make clinical decisions for individual patients, considering all of the parameters that must be considered to deliver personalised clinical management.

Abstract
BACKGROUND The aim of this study was to analyze the causes of death and risk factors of prostate-cancer-specific mortality (PCSM) and other-cause mortality (OCM) at different clinical stages using data from the Surveillance, Epidemiology, and End Results database. METHODS The characteristics and cause-specific death classifications of males with prostate cancer (PCa) were extracted. Multivariate competing-risk regression analysis was used to identify significant predictors and quantify the cumulative incidence of PCSM and OCM at different clinical stages. RESULTS Of the 244,433 PCa patients who were included, 19,274 died from 7356 PCSM, and 11,918 from OCM. The proportion of PCSM gradually increased from 2010 to 2016. The risk factors for PCSM in the localized PCa stage included older age, not being married, living in a county with higher poverty rates, and higher PSA levels and Gleason scores. Meanwhile, Medicaid and lower education levels were the additional risk factors of OCM. The risk factors for PCSM in the regional PCa stage included older age, not being married, Medicaid, living in a county with higher poverty rates, and higher PSA levels and Gleason scores. Meanwhile, the income level did not affect OCM risk. The risk factors for PCSM in the distant metastatic PCa stage included a separated/divorced/widowed marital status, Medicaid, and higher PSA levels and Gleason scores. Meanwhile, older age, an unmarried or separated/divorced/widowed marital status, and higher PSA levels were risk factors for OCM. In addition, receiving both surgery and radiation was worse than just receiving surgery for PCa specific survival in localized and regional PCa patients. CONCLUSION Some pretreatment and treatment factors may influence OCM that are not identical to those for PCSM at the corresponding stage. Decision-makers and managers should fully consider OCM to maximize treatment benefits for PCa.

Abstract
There have been major advances in the armamentarium for hepatocellular carcinoma (HCC) since the last official update of the Barcelona Clinic Liver Cancer prognosis and treatment strategy published in 2018. Whilst there have been advances in all areas, we will focus on those that have led to a change in strategy and we will discuss why, despite being encouraging, data for select interventions are still too immature for them to be incorporated into an evidence-based model for clinicians and researchers. Finally, we describe the critical insight and expert knowledge that are required to make clinical decisions for individual patients, considering all of the parameters that must be considered to deliver personalised clinical management.

Abstract
INTRODUCTION Prostate Imaging Reporting and Data System (PI-RADS) scores can help identify clinically significant prostate cancer and improve patient selection for prostate biopsies. However, the role of PI-RADS scores in patients already diagnosed with prostate cancer remains unclear. The purpose of this study was to evaluate the association of PI-RADS scores with prostate cancer upstaging. Upstaging on final pathology harbors a higher risk for biochemical recurrence with important implications for additional treatments, morbidity, and mortality. METHODS All patients from a single high-volume institution who underwent a prostate multiparametric magnetic resonance imaging and radical prostatectomy between 2016 and 2020 were included in this retrospective analysis. Univariable and multivariable analyses were conducted to investigate potential associations with upstaging events, defined by pT3, pT4, or N1 on final pathology. A logistic regression model was constructed for the prediction of upstaging events based on PI-RADS score, prostate-specific antigen density (PSA-D), and biopsy Gleason grade groups. We built receiver operative characteristic (ROC) curves to measure the area under the curve of different predictive models. RESULTS Two hundred and ninety-four patients were included in the final analysis. Upstaging events occurred in 137 (46.5%) of patients. On univariable analysis, patients who were upstaged on final pathology had significantly higher PI-RADS scores (odds ratio [OR] 2.34 95% confidence interval [CI] 1.64-3.40, p < 0.001) but similar PSA-D (OR 2.70 95% 0.94-8.43, p = 0.188) compared with patients who remained pT1 or pT2 on final pathology. On multivariable analysis, PI-RADS remained independently significantly associated with upstaging, suggesting it is an independent risk predictor for upstaging. Lymph node metastasis only occurred in patients with PI-RADS 4 or 5 lesions (n = 15). Our model using PSA-D, biopsy Gleason grade, and PI-RADS had a predictive AUC of 0.69 for upstaging events, an improvement from 0.59 using biopsy Gleason grade alone. CONCLUSION PI-RADS scores are independent predictors for upstaging events and may play an important role in forecasting biochemical recurrence and lymph node metastasis. Modern nomograms should be updated to include PI-RADS to predict lymph node metastases and the likelihood of biochemical recurrence more accurately.

Abstract
The research is aimed at investigating computed tomography (CT) image based on deep learning algorithm and the application value of ceramide glycosylation in diagnosing bladder cancer. The images of ordinary CT detection were improved. In this study, 60 bladder cancer patients were selected and performed with ordinary CT detection, and the detection results were processed by CT based on deep learning algorithms and compared with pathological diagnosis. In addition, Western Blot technology was used to detect the expression of glucose ceramide synthase (GCS) in the cell membrane of tumor tissues and normal tissues of bladder. The comparison results found that, in simple CT clinical staging, the coincidence rates of T1 stage, T2a stage, T2b stage, T3 stage, and T4 stage were 28.56%, 62.51%, 78.94%, 84.61%, and 74.99%, respectively; and the total coincidence rate of CT clinical staging was 63.32%, which was greatly different from the clinical staging of pathological diagnosis (P < 0.05). In the clinical staging of algorithm-based CT test results, the coincidence rates of T1 stage and T2a stage were 50.01% and 91.65%, respectively; and those of T2b stage, T3 stage, and T4 stage were 100.00%; and the total coincidence rate was 96.69%, which was not obviously different from the clinical staging of pathological diagnosis (P > 0.05). Therefore, it could be concluded that the algorithm-based CT detection results were more accurate, and the use of CT scans based on deep learning algorithms in the preoperative staging and clinical treatment of bladder cancer showed reliable guiding significance and clinical value. In addition, it was found that the expression level of GCS in normal bladder tissues was much lower than that in bladder cancer tissues. This indicated that the changes in GCS were closely related to the development and prognosis of bladder cancer. Therefore, it was believed that GCS may be an effective target for the treatment of bladder cancer in the future, and further research was needed for specific conditions.

Abstract
OBJECTIVE To evaluate the performance characteristics of AJCC 7th and 8th staging systems among patients with adrenal cortical carcinoma. METHODS Surveillance, Epidemiology, and End Results (SEER) 18-registry was accessed and patients with adrenocortical carcinoma who were diagnosed 2010-2015 with complete information about AJCC 7th staging system were included. AJCC 8th staging system information was then reconstructed for each patient using available TNM staging variables. Kaplan-Meier overall survival estimates, multivariable Cox regression analysis, and concordance index (C-statistic) were used to examine the performance characteristics of both staging systems. RESULTS A total of 574 patients with a diagnosis of adrenocortical carcinoma were included in the current analysis. Using Kaplan-Meier survival estimates, overall survival was compared among different AJCC stages for both versions; and the P value was significant (< 0.001) for both comparisons. C-statistic was then calculated for both staging systems and the results were as follows: for AJCC 7th version: 0.726 (95% CI 0.683-0.769); and for AJCC 8th version: 0.745 (95% CI 0.704-0.786). Patients with M1 disease (stage IV according to AJCC 8th edition) were then divided according to the extent of distant metastases into single versus multiple sites of metastases. Using Kaplan-Meier survival estimates, patients with a single site of metastases have better overall survival (P = 0.006). A C-statistic for a hypothetical modification of AJCC 8th staging system subdividing stage IV patients into IVA and IVB based on the number of metastatic sites was: 0.753 (95% CI 0.713-0.794). CONCLUSIONS There is a minimal difference in the prognostic performance between both versions of the AJCC staging system. Subdivision of stage IV cancer into stage IVA and IVB (according to the number of organs with metastatic deposits) should be considered in subsequent versions of adrenocortical carcinoma staging.

Abstract
OBJECTIVE To evaluate interobserver agreement for the assessment of local tumor extension in women with cervical cancer, among experienced and less experienced observers, using transvaginal ultrasound (TVS) and magnetic resonance imaging (MRI). METHODS The TVS observers were all gynecologists and consultant ultrasound specialists, six with and seven without previous experience in cervical cancer imaging. The MRI observers were five radiologists experienced in pelvic MRI and four less experienced radiology residents without previous experience in MRI of the pelvis. The less experienced TVS observers and all MRI observers underwent a short basic training session in the assessment of cervical tumor extension, while the experienced TVS observers received only a written directive. All observers were assigned the same images from cervical cancer patients at all stages (n = 60) and performed offline evaluation to answer the following three questions: (1) Is there a visible primary tumor? (2) Does the tumor infiltrate > ⅓ of the cervical stroma? and (3) Is there parametrial invasion? Interobserver agreement within the four groups of observers was assessed using Fleiss kappa (κ) with 95% CI. RESULTS Experienced and less experienced TVS observers, respectively, had moderate interobserver agreement with respect to tumor detection (κ (95% CI), 0.46 (0.40-0.53) and 0.46 (0.41-0.52)), stromal invasion > ⅓ (κ (95% CI), 0.45 (0.38-0.51) and 0.53 (0.40-0.58)) and parametrial invasion (κ (95% CI), 0.57 (0.51-0.64) and 0.44 (0.39-0.50)). Experienced MRI observers had good interobserver agreement with respect to tumor detection (κ (95% CI), 0.70 (0.62-0.78)), while less experienced MRI observers had moderate agreement (κ (95% CI), 0.51 (0.41-0.62)), and both experienced and less experienced MRI observers, respectively, had good interobserver agreement regarding stromal invasion (κ (95% CI), 0.80 (0.72-0.88) and 0.71 (0.61-0.81)) and parametrial invasion (κ (95% CI), 0.69 (0.61-0.77) and 0.71 (0.61-0.81)). CONCLUSIONS We found interobserver agreement for the assessment of local tumor extension in patients with cervical cancer to be moderate for TVS and moderate-to-good for MRI. The level of interobserver agreement was associated with experience among TVS observers only for parametrial invasion. © 2021 The Authors.

Abstract
BACKGROUND The majority of primary liver cancers in adults worldwide are hepatocellular carcinomas (HCCs, or hepatomas). Thus, a deep understanding of the underlying mechanisms for the pathogenesis and carcinogenesis of HCC at the molecular level could facilitate the development of novel early diagnostic and therapeutic treatments to improve the approaches and prognosis for HCC patients. Our study elucidates the underlying molecular mechanisms of HBV-HCC development and progression and identifies important genes related to the early diagnosis, tumour stage, and poor outcomes of HCC. METHODS GSE55092 and GSE121248 gene expression profiling data were downloaded from the Gene Expression Omnibus (GEO) database. There were 119 HCC samples and 128 nontumour tissue samples. GEO2R was used to screen for differentially expressed genes (DEGs). Volcano plots and Venn diagrams were drawn by using the ggplot2 package in R. A heat map was generated by using Heatmapper. By using the clusterProfiler R package, KEGG and GO enrichment analyses of DEGs were conducted. Through PPI network construction using the STRING database, key hub genes were identified by cytoHubba. Finally, KM survival curves and ROC curves were generated to validate hub gene expression. RESULTS By GO enrichment analysis, 694 DEGs were enriched in the following GO terms: organic acid catabolic process, carboxylic acid catabolic process, carboxylic acid biosynthetic process, collagen-containing extracellular matrix, blood microparticle, condensed chromosome kinetochore, arachidonic acid epoxygenase activity, arachidonic acid monooxygenase activity, and monooxygenase activity. In the KEGG pathway enrichment analysis, DEGs were enriched in arachidonic acid epoxygenase activity, arachidonic acid monooxygenase activity, and monooxygenase activity. By PPI network construction and analysis of hub genes, we selected the top 10 genes, including CDK1, CCNB2, CDC20, BUB1, BUB1B, CCNB1, NDC80, CENPF, MAD2L1, and NUF2. By using TCGA and THPA databases, we found five genes, CDK1, CDC20, CCNB1, CENPF, and MAD2L1, that were related to the early diagnosis, tumour stage, and poor outcomes of HBV-HCC. CONCLUSIONS Five abnormally expressed hub genes of HBV-HCC are informative for early diagnosis, tumour stage determination, and poor outcome prediction.

Abstract
BACKGROUND Socioeconomic and treatment factors contribute to diagnosis of early-stage (local-stage) breast cancer, as well as excess deaths among African American women. OBJECTIVES We evaluated socioeconomic and treatment predictive factors for early-stage breast cancer among African American women compared to Caucasian women. A secondary aim evaluated predictors and overall risks associated with all-cause and breast cancer-specific mortality. METHODS We used retrospective cohort population-based study data from the Surveillance, Epidemiology, and End Results (SEER) Program on 547,703 women aged ≥ 20 years diagnosed with breast cancer primary tumors from 2007 to 2016. Statistical analysis used logistic regression to assess predictors of early-stage breast cancer and Cox proportional hazards regression for mortality risks. RESULTS African American women were more likely to be diagnosed at advanced-stage, had larger tumor size at diagnosis, and received less cancer-directed surgery, but more chemotherapy than Caucasian women. Insured women (> 50%) were more likely to be diagnosed at early-stage and to have smaller tumors (p < 0.05). Education level, poverty level, and household income had no impact on racial disparities or socioeconomic disparities in women diagnosed at early stage. We found increased risks for all-cause mortality (hazard ratio = 1.18; 95% confidence interval, 1.16-1.21) and breast cancer-specific mortality (HR = 1.22; 95% CI, 1.19-1.25) among African American women compared to Caucasian women after adjusting for demographic, socioeconomic, and treatment factors. CONCLUSIONS In this population-based study using the most recent SEER data, African American women with breast cancer continued to exhibit higher all-cause mortality and breast cancer-specific mortality compared to Caucasian women.

Abstract
BACKGROUND The prognosis and treatment of basal cell carcinoma (BCC) are largely dependent on tumor subtype, which is typically determined by punch or shave biopsy. Data regarding concordance between BCC subtype on initial biopsy and final histopathology for Mohs micrographic surgery (MMS) or excision with frozen sections (EFS) are limited. OBJECTIVES To determine the concordance between initial biopsy and final MMS or EFS subtyping of BCC. We aim to investigate the incidence and clinical characteristics of lesions initially diagnosed as superficial BCC (sBCC) that are later found to have a nodular, micronodular, or infiltrative component. METHODS We conducted a retrospective review of all MMS or EFS cases performed at a single academic center from August 1, 2015 to August 31, 2017. Inclusion criteria were a biopsy-proven diagnosis of sBCC and presence of residual tumor following stage I of MMS or EFS. Fisher’s exact test was used to evaluate significance of clinical characteristics and outcomes associated with the presence of a nodular, micronodular, or infiltrative BCC component. RESULTS A total of 164 MMS or EFS cases had an initial biopsy showing sBCC. Of these, 117 had residual BCC on stage I, and 43 (37%) were found to have a nodular, micronodular, or infiltrative component. Significant predictors of reclassified BCC subtype included age over 60 years (P=0.006) and location on the head or neck (P=0.043). Reclassified lesions required significantly more stages of MMS to clear (P=0.036). Shave biopsy was used to diagnose 114 (98%) of the included cases. CONCLUSIONS Over one third of shave biopsies that initially diagnosed sBCC failed to detect a nodular, micronodular, or infiltrative component. Management of biopsy-proven sBCC should take into account the possible presence of an undiagnosed deeper tumor component with appropriate margin-assessment treatment modalities when clinically indicated.

Abstract
IMPORTANCE The association of the Patient Protection and Affordable Care Act (ACA) with insurance status and cancer stage at diagnosis among patients with renal cell carcinoma (RCC) is unknown. OBJECTIVE To test the hypothesis that the ACA may be associated with increased access to care through expansion of insurance, which may vary based on income. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort analysis included patients diagnosed with RCC from January 1, 2010, to December 31, 2016, in the National Cancer Database. Data were analyzed from July 1 to December 31, 2020. The periods from 2010 to 2013 and from 2014 to 2016 were defined as pre- and post-ACA implementation, respectively. Patients were categorized as living in a Medicaid expansion state or not. EXPOSURES Implementation of the ACA. MAIN OUTCOMES AND MEASURES The absolute percentage change (APC) of insurance coverage was calculated before and after ACA implementation in expansion and nonexpansion states. Secondary outcomes included change in stage at diagnosis, difference in the rate of insurance change, and change in localized disease between expansion and nonexpansion states. Adjusted difference-in-difference modeling was performed. RESULTS The cohort included 78 099 patients (64.7% male and 35.3% female; mean [SD] age, 54.66 [6.46] years), of whom 21.2% had low, 46.2% had middle, and 32.6% had high incomes. After ACA implementation, expansion states had a lower proportion of uninsured patients (adjusted difference-in-difference, -1.14% [95% CI, -1.98% to -1.41%]; P = .005). This occurred to the greatest degree among low-income patients through the acquisition of Medicaid (APC, 11.0% [95% CI, 8.6%-13.3%]; P < .001). Implementation of the ACA was also associated with an increase in detection of stage I and II disease (APC, 4.0% [95% CI, 1.6%-6.3%]; P = .001) among low-income patients in expansion states. CONCLUSIONS AND RELEVANCE Among patients with RCC, ACA implementation was associated with an increase in insurance coverage status in both expansion and nonexpansion states for all income groups, but to a greater degree in expansion states. The proportion of patients with localized disease increased among low-income patients in both states. These data suggest that ACA implementation is associated with earlier RCC detection among lower-income patients.

Abstract
IMPORTANCE Health care costs associated with diagnosis and care among older adults with multiple myeloma (MM) are substantial, with cost of care and the factors involved differing across various phases of the disease care continuum, yet little is known about cost of care attributable to MM from a Medicare perspective. OBJECTIVE To estimate incremental phase-specific and lifetime costs and cost drivers among older adults with MM enrolled in fee-for-service Medicare. DESIGN, SETTING, AND PARTICIPANTS A retrospective cohort study was conducted using population-based registry data from the 2007-2015 Surveillance, Epidemiology, and End Results database linked with 2006-2016 Medicare administrative claims data. Data analysis included 4533 patients with newly diagnosed MM and 4533 matched noncancer Medicare beneficiaries from a 5% sample of Medicare to assess incremental MM lifetime and phase-specific costs (prediagnosis, initial care, continuing care, and terminal care) and factors associated with phase-specific incremental MM costs. The study was conducted from June 1, 2019, to April 30, 2021. MAIN OUTCOMES AND MEASURES Incremental MM costs were calculated for the disease lifetime and the following 4 phases of care: prediagnosis, initial, continuing care, and terminal. RESULTS Of the 4533 patients with MM included in the study, 2374 were women (52.4%), 3418 (75.4%) were White, and mean (SD) age was 75.8 (6.8) years (2313 [51.0%] aged ≥75 years). The characteristics of the control group were similar; however, mean (SD) age was 74.2 (8.8) years (2839 [62.6%] aged ≤74 years). Mean adjusted incremental MM lifetime costs were $184 495 (95% CI, $183 099-$185 968). Mean per member per month phase-specific incremental MM costs were estimated to be $1244 (95% CI, $1216-$1272) for the prediagnosis phase, $11 181 (95% CI, $11 052-$11 309) for the initial phase, $5634 (95% CI, $5577-$5694) for the continuing care phase, and $6280 (95% CI, $6248-$6314) for the terminal phase. Although inpatient and outpatient costs were estimated as the major cost drivers for the prediagnosis (inpatient, 55.8%; outpatient, 40.2%), initial care (inpatient, 38.1%; outpatient, 35.5%), and terminal (inpatient, 33.0%; outpatient, 34.6%) care phases, prescription drugs (44.9%) were the largest cost drivers in the continuing care phase. CONCLUSIONS AND RELEVANCE The findings of this study suggest that there is substantial burden to Medicare associated with diagnosis and care among older adults with MM, and the cost of care and cost drivers vary across different phases of the cancer care continuum. The study findings might aid policy discussions regarding MM care and coverage and help further the development of alternative payment models for MM, accounting for differential costs across various phases of the disease continuum and their drivers.

Abstract
BACKGROUND The Will Rogers phenomenon [WRP] describes an apparent improvement in outcome for patients' group due to tumor grade reclassification. Staging of cancers is important to select appropriate treatment and to estimate prognosis. The WRP has been described as one of the most important biases limiting the use of historical cohorts when comparing survival or treatment. The main purpose of this study is to assess whether the WRP exists with the move from the AJCC 7th to AJCC 8th edition in breast cancer [BC] staging, and if racial differences are manifested in the expression of the WRP. METHODS This is a retrospective analysis of 300 BC women (2007-2017) at an academic medical center. Overall survival [OS] and disease-free survival [DFS] was estimated by Kaplan-Meier analysis. Bi and multi-variate Cox regression analyses was used to identify racial factors associated with outcomes. RESULTS Our patient cohort included 30.3% Caucasians [Whites] and 69.7% African-Americans [Blacks]. Stages I, II, III, and IV were 46.2, 26.3, 23.1, and 4.4% of Whites; 28.7, 43.1, 24.4, and 3.8% of Blacks respectively, in anatomic staging (p = 0.043). In prognostic staging, 52.8, 18.7, 23, and 5.5% were Whites while 35, 17.2, 43.5, and 4.3% were Blacks, respectively (p = 0.011). A total of Whites (45.05% vs. 47.85%) Blacks, upstaged. Whites (16.49% vs. 14.35%) Blacks, downstaged. The remaining, 38.46 and 37.79% patients had their stages unchanged. With a median follow-up of 54 months, the Black patients showed better stage-by-stage 5-year OS rates using 8th edition compared to the 7th edition (p = 0.000). Among the Whites, those who were stage IIIA in the 7th but became stage IB in the 8th had a better prognosis than stages IIA and IIB in the 8th (p = 0.000). The 8th showed complex results (p = 0.176) compared to DFS estimated using the 7th edition (p = 0.004). CONCLUSION The WRP exists with significant variability in the move from the AJCC 7th to the 8th edition in BC staging (both White and Black patients). We suggest that caution needs to be exercised when results are compared across staging systems to account for the WRP in the interpretation of the data.

Clin Orthop Relat Res 2021; 479:493-502. [PMID: 32805094 PMCID: PMC7899708 DOI: 10.1097/corr.0000000000001438] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [What about the content of this article?

Abstract
BACKGROUND Treatment of bone and soft-tissue sarcomas can be costly, and therefore, it is not surprising that insurance status of patients is a prognostic factor in determining overall survival. Furthermore, uninsured individuals with suspected bone and/or soft-tissue masses routinely encounter difficulty in obtaining access to basic healthcare (such as office visits, radiology scans), and therefore are more likely to be diagnosed with later stages at presentation. The Patient Protection and Affordable Care Act (ACA) mandate of 2010 aimed to increase access to care for uninsured individuals by launching initiatives, such as expanding Medicaid eligibility, subsidizing private insurance, and developing statewide mandates requiring individuals to have a prescribed minimum level of health insurance. Although prior reports have demonstrated that the ACA increased both coverage and the proportion of early-stage diagnoses among patients with common cancers (including breast, colon, prostate, and lung), it is unknown whether similar improvements have occurred for patients with bone and soft-tissue sarcomas. Understanding changes in insurance coverages and stage at diagnosis of patients with bone and soft-tissue sarcomas would be paramount in establishing policies that will ensure orthopaedic cancer care is made equitable and accessible to all. QUESTIONS/PURPOSES (1) Has the introduction of the ACA been associated with changes in insurance coverage for adult patients with newly diagnosed bone and soft-tissue sarcomas? (2) Did the introduction of health reforms under the ACA lead to an increased proportion of sarcoma diagnoses occurring at earlier disease stages? METHODS The 2007 to 2015 Surveillance, Epidemiology and End Results database was queried using International Classification of Diseases for Oncology codes for primary malignant bone tumors of the upper and lower extremity (C40.0 to C40.3), unspecified or other overlapping bone, articular cartilage, and joint and/or ribs, sternum, or clavicle (C40.8 to C40.9, C41.3, and C41.8 to C41.9), vertebral column (C41.2), pelvis (C41.4, C41.8, and C41.9), and soft-tissue sarcomas of the upper or lower extremity and/or pelvis (C49.1, C49.2, and C49.5). A total of 15,287 patients with newly diagnosed cancers were included, of which 3647 (24%) were malignant bone tumors and 11,640 (76%) were soft-tissue sarcomas. The study sample was divided into three cohorts according to specified time periods: pre-ACA from 2007 to 2010 (6537 patients), pre-Medicaid expansion from 2011 to 2013 (5076 patients), and post-Medicaid expansion from 2014 to 2015 (3674 patients). The Pearson chi square tests were used to assess for changes in the proportion of Medicaid and uninsured patients across the specified time periods: pre-ACA, pre-expansion and post-expansion. A differences-in-differences analysis was also performed to assess changes in insurance coverage for Medicaid and uninsured patients among states that chose to expand Medicaid coverage in 2014 under the ACA's provision versus those who opted out of Medicaid expansion. Since the database switched to using the American Joint Commission on Cancer (AJCC) 7th edition staging system in 2010, linear regression using data only from 2010 to 2015 was performed that assessed changes in cancer stage at diagnosis from 2010 to 2015 alone. After stratifying by cancer type (bone or soft-tissue sarcoma), Pearson chi square tests were used to assess for changes in the proportion of patients who were diagnosed with early, late, and unknown stage at presentation before Medicaid expansion (2011-2013) and after Medicaid expansion (2014-2015) among states that chose to expand versus those who did not. RESULTS After stratifying by time cohorts: pre-ACA (2007 to 2010), pre-expansion (2011 to 2013) and post-expansion (2014 to 2015), we observed that the most dramatic changes occurred after Medicaid eligibility was expanded (2014 onwards), with Medicaid proportions increasing from 12% (pre-expansion, 2011 to 2013) to 14% (post-expansion, 2014 to 2015) (p < 0.001) and uninsured proportions decreasing from 5% (pre-expansion, 2011 to 2013) to 3% (post-expansion, 2014 to 2015) (p < 0.001). A differences-in-differences analysis that assessed the effect of Medicaid expansion showed that expanded states had an increase in the proportion of Medicaid patients compared with non-expanded states, (3.6% [95% confidence interval 0.4 to 6.8]; p = 0.03) from 2014 onwards. For the entire study sample, the proportion of early-stage diagnoses (I/II) increased from 56% (939 of 1667) in 2010 to 62% (1137 of 1840) in 2015 (p = 0.003). Similarly, the proportion of unknown stage diagnoses decreased from 11% (188 of 1667) in 2010 to 7% (128 of 1840) in 2015 (p = 0.002). There was no change in proportion of late-stage diagnoses (III/IV) from 32% (540 of 1667) in 2010 to 31% (575 of 1840) in 2015 (p = 0.13). CONCLUSION Access to cancer care for patients with primary bone or soft-tissue sarcomas improved after the ACA was introduced, as evidenced by a decrease in the proportion of uninsured patients and corresponding increase in Medicaid coverage. Improvements in coverage were most significant among states that adopted the Medicaid expansion of 2014. Furthermore, we observed an increasing proportion of early-stage diagnoses after the ACA was implemented. The findings support the preservation of the ACA to ensure cancer care is equitable and accessible to all vulnerable patient populations. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
Until recently, cancer registries have only collected cancer clinical stage at diagnosis, before any therapy, and pathological stage after surgical resection, provided no treatment has been given before the surgery, but they have not collected stage data after neoadjuvant therapy (NAT). Because NAT is increasingly being used to treat a variety of tumors, it has become important to make the distinction between both the clinical and the pathological assessment without NAT and the assessment after NAT to avoid any misunderstanding of the significance of the clinical and pathological findings. It also is important that cancer registries collect data after NAT to assess response and effectiveness of this treatment approach on a population basis. The prefix y is used to denote stage after NAT. Currently, cancer registries of the American College of Surgeons' Commission on Cancer only partially collect y stage data, and data on the clinical response to NAT (yc or posttherapy clinical information) are not collected or recorded in a standardized fashion. In addition to NAT, nonoperative management after radiation and chemotherapy is being used with increasing frequency in rectal cancer and may be expanded to other treatment sites. Using examples from breast, rectal, and esophageal cancers, the pathological and imaging changes seen after NAT are reviewed to demonstrate appropriate staging.

Abstract
BACKGROUND Merkel cell carcinoma (MCC) guidelines derive from melanoma and do not recommend baseline cross-sectional imaging for most patients. However, MCC is more likely to have metastasized at diagnosis than melanoma. OBJECTIVE To determine how often baseline imaging identifies clinically occult MCC in patients with newly diagnosed disease with and without palpable nodal involvement. METHODS Analysis of 584 patients with MCC with a cutaneous primary tumor, baseline imaging, no evident distant metastases, and sufficient staging data. RESULTS Among 492 patients with clinically uninvolved regional nodes, 13.2% had disease upstaged by imaging (8.9% in regional nodes, 4.3% in distant sites). Among 92 patients with clinically involved regional nodes, 10.8% had disease upstaged to distant metastatic disease. Large (>4 cm) and small (<1 cm) primary tumors were both frequently upstaged (29.4% and 7.8%, respectively). Patients who underwent positron emission tomography-computed tomography more often had disease upstaged (16.8% of 352), than those with computed tomography alone (6.9% of 231; P = .0006). LIMITATIONS This was a retrospective study. CONCLUSIONS In patients with clinically node-negative disease, baseline imaging showed occult metastatic MCC at a higher rate than reported for melanoma (13.2% vs <1%). Although imaging is already recommended for patients with clinically node-positive MCC, these data suggest that baseline imaging is also indicated for patients with clinically node-negative MCC because upstaging is frequent and markedly alters management and prognosis.

Abstract
BACKGROUND To analyse the early stage breast cancer tumour size distribution as an important prognostic factor among the female patients within our local geographic region of Herzegovina. SUBJECTS AND METHODS This cross-sectional retrospective study included 379 patients who were treated in 2017 at the Oncology Clinic, University Clinical Hospital Mostar. The patients were divided into two groups based on their primary tumour size: early (≤2 cm) and late (>2 cm) stage groups. RESULTS The number of patients tested for advanced stage tumours surpassing 2 cm was statistically higher (χ2=106,325; p<0.001). 39.32% (N=149) of the patients presented with tumours ≤2 cm (T1) and 52.24% (N=198) of the total number of the patients presented with tumours >2 cm but ≤5 cm in greatest dimension (T2). The patients' knowledge about breast cancer, availability and adherence of mammography did not show any statistically significant difference with regard to tumour size, while the number of patients with smaller tumours who indicated that they underwent regular mammography was statistically significantly higher (χ2=13,629; p<0.003). CONCLUSIONS Our data shows that in our region, more women with a diagnosis of breast cancer presented with a larger tumor size. Although there was no statistically significant difference with regard to prior knowledge about breast cancer and availability to mammography, this may be due to a small sample size. Our region does not have a screening mammogram program and this data suggests that the implementation of such a program may improve adherence to existing mammography guidelines which might capture tumors at a smaller size and hence an earlier stage.

Abstract
The incidence of nonmelanoma skin cancer (NMSC) in the United States is increasing with approximately 3.6 million cases diagnosed per year. The staging and treatment of NMSC is guided by histologic subtype based on skin biopsy, along with other tumor-specific factors. However, a biopsy only represents a portion of the tumor, so there is a risk of upstaging at the time of definitive surgery. We conducted a review of the literature and found that a significant proportion of NMSC were upstaged during surgery. The rate of upstaging of basal cell carcinoma (BCC) was 7-31% and that of squamous cell carcinoma in situ (SCCIS) to squamous cell carcinoma (SCC) was 3-39%. Biopsy sampling error and variability in interpreting and reporting by dermatopathologists contribute to these discrepancies. It is pertinent to consider more comprehensive treatment modalities for tumors at high risk for upstaging. Diligence to identify tumors at higher risk for upstaging will allow clinicians to optimize management.

Abstract
OBJECTIVE To investigate differences in local tumour staging between clinical examination and MRI and differences between FIGO 2009, FIGO 2018 and TNM in patients with primary cervical cancer undergoing definitive radio-chemotherapy. METHODS Patients from the prospective observational multi-centre study "EMBRACE" were considered for analysis. All patients had gynaecological examination and pelvic MRI before treatment. Nodal status was assessed by MRI, CT, PET-CT or lymphadenectomy. For this analysis, patients were restaged according to the FIGO 2009, FIGO 2018 and TNM staging system. The local tumour stage was evaluated for MRI and clinical examination separately. Descriptive statistics were used to compare local tumour stages and different staging systems. RESULTS Data was available from 1338 patients. For local tumour staging, differences between MRI and clinical examination were found in 364 patients (27.2%). Affected lymph nodes were detected in 52%. The two most frequent stages with FIGO 2009 are IIB (54%) and IIIB (16%), with FIGO 2018 IIIC1 (43%) and IIB (27%) and with TNM T2b N0 M0 (27%) and T2b N1 M0 (23%) in this cohort. CONCLUSIONS MRI and clinical examination resulted in a different local tumour staging in approximately one quarter of patients. Comprehensive knowledge of the differential value of clinical examination and MRI is necessary to define one final local stage, especially when a decision about treatment options is to be taken. The use of FIGO 2009, FIGO 2018 and TNM staging system leads to differences in stage distributions complicating comparability of treatment results. TNM provides the most differentiated stage allocation.

Abstract
IMPORTANCE Systematically capturing cancer stage is essential for any serious effort by health systems to monitor outcomes and quality of care in oncology. However, oncologists do not routinely record cancer stage in machine-readable structured fields in electronic health records (EHRs). OBJECTIVE To evaluate whether a peer comparison email intervention that communicates an oncologist's performance on documenting cancer stage relative to that of peer physicians was associated with increased likelihood that stage was documented in the EHR. DESIGN, SETTING, AND PARTICIPANTS This 12-month, randomized quality improvement pilot study aimed to increase oncologist staging documentation in the EHR. The pilot study was performed at Massachusetts General Hospital Cancer Center from October 1, 2018, to September 30, 2019. Participants included 56 oncologists across 3 practice sites who treated patients in the ambulatory setting and focused on diseases that use standardized staging systems. Data were analyzed from July 2, 2019, to March 5, 2020. INTERVENTIONS Peer comparison intervention with as many as 3 emails to oncologists during 6 months that displayed the oncologist's staging documentation rate relative to all oncologists in the study sample. MAIN OUTCOMES AND MEASURES The primary outcome was patient-level documentation of cancer stage, defined as the likelihood that a patient's stage of disease was documented in the EHR after the patient's first (eg, index) ambulatory visit during the pilot period. RESULTS Among the 56 oncologists participating (32 men [57%]), receipt of emails with peer comparison data was associated with increased likelihood of documentation of cancer stage using the structured field in the EHR (23.2% vs 13.0% of patient index visits). In adjusted analyses, this difference represented an increase of 9.0 (95% CI, 4.4-13.5) percentage points (P = .002) in the probability that a patient's cancer stage was documented, a relative increase of 69% compared with oncologists who did not receive peer comparison emails. The association increased with each email that was sent, ranging from a nonsignificant 4.0 (95% CI, -0.8 to 8.8) percentage points (P = .09) after the first email to a statistically significant 11.2 (95% CI, 4.9-17.4) percentage points (P = .003) after the third email . The association was concentrated among an oncologist's new patients (increase of 11.8 [95% CI, 6.2-17.4] percentage points; P = .001) compared with established patients (increase of 1.6 [95% CI, -2.9 to 6.1] percentage points; P = .44) and persisted for 7 months after the email communications stopped. CONCLUSIONS AND RELEVANCE In a quality improvement pilot trial, peer comparison emails were associated with a substantial increase in oncologist use of the structured field in the EHR to document stage of disease.

Abstract
OBJECTIVES To compare risks of distant-stage colorectal cancer (CRC) diagnosis between whites and American Indian/Alaska Natives (AI/ANs) and to explore effect modification by area-based socioeconomic status (SES). DESIGN Retrospective cohort study using data from the Oklahoma Central Cancer Registry. SETTING Oklahoma. PARTICIPANTS White and AI/AN cases of CRC diagnosed in Oklahoma between 2001 and 2008 (N = 8 438). A subanalysis was performed on the cohort of those aged 50 years and older (N = 7 728). MAIN OUTCOME MEASURE Risk of distant-stage CRC diagnosis stratified by SES score. RESULTS Race and SES were independently associated with distant-stage diagnosis. In SES-stratified analyses, AI/ANs in the 2 lowest SES groups experienced increased risks in the overall cohort and among those aged 50 years and older. In multivariable models, risks remained significant among those aged 50 years and older in the lowest SES groups (Adjusted risk ratio SES score of 2: 1.31, 95% confidence interval: 1.06-1.63 and adjusted risk ratio SES score of 1: 1.21, 95% confidence interval: 1.01-1.44). CONCLUSION Socioeconomic status is an effect modifier in the association between race/ethnicity and stage at CRC diagnosis. Disparities in stage at CRC diagnosis exist between AI/ANs and whites with lower estimated SES. Efforts are needed to increase CRC screening among lower SES AI/ANs.

Abstract
Analysis with time-to-event data in clinical and epidemiological studies often encounters missing covariate values, and the missing at random assumption is commonly adopted, which assumes that missingness depends on the observed data, including the observed outcome which is the minimum of survival and censoring time. However, it is conceivable that in certain settings, missingness of covariate values is related to the survival time but not to the censoring time. This is especially so when covariate missingness is related to an unmeasured variable affected by the patient's illness and prognosis factors at baseline. If this is the case, then the covariate missingness is not at random as the survival time is censored, and it creates a challenge in data analysis. In this article, we propose an approach to deal with such survival-time-dependent covariate missingness based on the well known Cox proportional hazard model. Our method is based on inverse propensity weighting with the propensity estimated by nonparametric kernel regression. Our estimators are consistent and asymptotically normal, and their finite-sample performance is examined through simulation. An application to a real-data example is included for illustration.

Abstract
IMPORTANCE Information about stage of cancer at diagnosis, use of therapy, and survival among patients from different racial/ethnic groups with 1 of the most common cancers is lacking. OBJECTIVE To assess stage of cancer at diagnosis, use of therapy, overall survival (OS), and cancer-specific survival (CSS) in patients with cancer from different racial/ethnic groups. DESIGN, SETTING, AND PARTICIPANTS This cohort study included 950 377 Asian, black, white, and Hispanic patients who were diagnosed with prostate, ovarian, breast, stomach, pancreatic, lung, liver, esophageal, or colorectal cancers from January 2004 to December 2010. Data were collected using the Surveillance, Epidemiology, and End Results (SEER) database, and patients were observed for more than 5 years. Data analysis was conducted in July 2018. MAIN OUTCOMES AND MEASURES Multivariable logistic and Cox regression were used to evaluate the differences in stage of cancer at diagnosis, treatment, and survival among patients from different racial/ethnic groups. RESULTS A total of 950 377 patients (499 070 [52.5%] men) were included in the study, with 681 251 white patients (71.7%; mean [SD] age, 65 [12] years), 116 015 black patients (12.2%; mean [SD] age, 62 [12] years), 65 718 Asian patients (6.9%; mean [SD] age, 63 [13] years), and 87 393 Hispanic patients (9.2%; mean [SD] age, 61 [13] years). Compared with Asian patients, black patients were more likely to have metastatic disease at diagnosis (odds ratio [OR], 1.144; 95% CI, 1.109-1.180; P < .001). Black and Hispanic patients were less likely to receive definitive treatment than Asian patients (black: adjusted OR, 0.630; 95% CI, 0.609-0.653; P < .001; Hispanic: adjusted OR, 0.751; 95% CI, 0.724-0.780; P < .001). White, black, and Hispanic patients were more likely to have poorer CSS and OS than Asian patients (CSS, white: adjusted HR, 1.310; 95% CI, 1.283-1.338; P < .001; black: adjusted HR, 1.645; 95% CI, 1.605-1.685; P < .001; Hispanic: adjusted HR, 1.300; 95% CI, 1.266-1.334; P < .001; OS, white: adjusted HR, 1.333; 95% CI, 1.310-1.357; P < .001; black: adjusted HR, 1.754; 95% CI, 1.719-1.789; P < .001; Hispanic: adjusted HR, 1.279; 95% CI, 1.269-1.326; P < .001). CONCLUSIONS AND RELEVANCE In this study of patients with 1 of 9 leading cancers, stage at diagnosis, treatment, and survival were different by race and ethnicity. These findings may help to optimize treatment and improve outcomes.

Abstract
Background and objectives: With improved diagnostic means of early breast cancer, the percentage of cases with metastasis in axillary lymph nodes has decreased from 50–75% to 15–30%. Lymphadenectomy and sentinel lymph node biopsy are not treatment procedures, as they aim at axillary nodal staging in breast cancer. Being surgical interventions, they can lead to various complications. Therefore, recently much attention has been paid to the identification of non-invasive methods for axillary nodal staging. In many countries, ultrasound is a first-line method to evaluate axillary lymph node status. The aim of this study was to evaluate the prognostic value of ultrasound in detecting intact axillary lymph nodes and to assess the accuracy of ultrasound in detecting a heavy nodal disease burden. The additional objective was to evaluate patients’ and tumor characteristics leading to false-negative results. Materials and Methods: A total of 227 women with newly diagnosed pT1 breast cancer were included to this prospective study conducted at the Breast Surgery Unit, Clinic of Surgery, Hospital of Lithuanian University of Health Sciences Kauno Klinikos, between May 1, 2016, and May 31, 2018. All patients underwent preoperative axillary ultrasound examination. Ultrasound data were compared with the results of histological examination. The accuracy and true-negative rate of ultrasound were calculated. The reasons of false-negative results were analyzed. Results: Of the 189 patients who had normally appearing axillary lymph nodes on preoperative ultrasound (PAUS-negative), 173 (91.5%) patients were also confirmed to have intact axillary lymph nodes (node-negative) by histological examination after surgery. The accuracy and the negative predictive value of ultrasound examination were 84.1% and 91.5%, respectively. In ≥3 node-positive cases, the accuracy and the negative predictive value increased to 88.7% and 98.3%, respectively. In total, false-negative results were found in 8.5% of the cases (n = 16); in the PAUS-negative group, false-negative results were recorded only in 1.6% of the cases (n = 3). The results of PAUS and pathological examination differed significantly between patients without and with lymphovascular invasion (LV0 vs. LV1, p < 0.001) as well as those showing no human epidermal growth factor receptor 2 (HER2) expression and patients with weakly or strongly expressed HER2 (HER2(0) vs. HER2(1), p = 0.024). Paired comparisons revealed that the true-negative rate was significantly different between the LV0 and LV1 groups (91% vs. 66.7%, p < 0.05), and the false-negative rate was statistically significant different between the HER2(0) and HER2(1) groups (10.5% vs. 1.2%, p < 0.05). Evaluation of other characteristics showed both the groups to be homogenous. Conclusions: Negative axillary ultrasound excluded axillary metastatic disease in 91.5% of the patients. PAUS had an accuracy of 88.7% in detecting a heavy nodal disease burden. With the absence of lymphovascular invasion (LV0), we can rely on PAUS examination that axillary lymph nodes are intact (PAUS-negative), and this patients’ group could avoid sentinel lymph node biopsy. Patients without HER2 expression are at a greater likelihood of false-negative results; therefore, the findings of ultrasound that axillary lymph nodes are intact (PAUS-negative results) should be interpreted with caution.

Abstract
Māori are more likely than non-Māori to get cancer, and once they have cancer they are less likely to survive it. One frequently proposed explanation for this survival disparity is differences between these groups in terms of stage at diagnosis-whereby Māori may be less likely to be diagnosed at an earlier stage, when treatment is more feasible and outcomes are better for the patient. However, this simple explanation ignores the true complexity of the issue of stage at diagnosis as a driver of survival disparities, and makes critical assumptions about the quality of available staging data. In this manuscript we draw on New Zealand Cancer Registry and available clinical audit data to explore this issue in detail. We found that Māori are less likely than European/Other patients to have localised disease and more likely to have advanced disease for several commonly diagnosed cancers; however, we also found that this was not the case for several key cancers, including lung and liver cancer. There is evidence that Māori have more advanced disease at diagnosis for each of the cancers for which we currently have a national screening programme, reinforcing the importance of achieving equity in access to these programmes. Missing stage information on our national registry undermines our ability to both a) monitor progress towards achieving early diagnosis, and b) examine and monitor the role of stage at diagnosis as a driver of survival disparities for several important cancers for Māori, including lung, liver and stomach cancers.

Abstract
Background We investigated the relationship between myometrial invasion and the prognostic factors on overall and progression free survival in endometrial carcinoma. Methods 122 cases operated with endometrial cancer were included into the study. Progression-free survival and overall survival were evaluated according to degree of myometrial invasion. We also investigated the relationship between myometrial invasion and prognostic factors. Results The 5- year progression-free survival rate was 90 % in stage I, 66 % in stage II, 32 % in stage III and 60 % in stage IV. The 5- year overall survival rate was 95 % in stage I, 89 % in stage II, 49 % in stage III and 30 % in stage IV. The progression free survival and overall survival for patients with more than 50 % myometrial invasion were detected 67 % at 58 months and 66 % at 60 months, respectively. The clinicopathological variables that significantly correlated with myometrial invasion of more than 50 % were as follows: pelvic lymph node metastasis (p: 0,00029-OR: 11.2), cervical stromal invasion (p: 0008-OR:7.9), LVSI (p< 0.0001-OR: 16.5). Conclusion The depth of myometrial invasion is one of the most important prognostic indicators and determinants of therapy in endometrial cancer.

Abstract
RATIONALE, AIMS, AND OBJECTIVES Different health agencies in Canada including Cancer Care Ontario (CCO) have developed guidelines for the baseline staging of newly diagnosed breast cancer patients but adherence to them is unknown. We sought to investigate adherence to CCO staging guidelines in a single cancer center in addition to the factors that influence this adherence. METHOD A retrospective chart review was conducted on 212 newly diagnosed breast cancer patients between 2015 and 2017. Baseline patient demographic and disease characteristics as well as radiologic staging studies and subsequent treatments were recorded. The group of patients in whom the guidelines were observed was compared to the group of patients in whom the guidelines were not followed. RESULTS Staging guidelines were not followed in 46.7% of the patients in the cohort (99 of 212 patients). In most cases, deviations from the guidelines consisted of performing more than the recommended baseline screening, most commonly in the form of a computerized tomography (CT) scan or a bone scan and chest x-ray (CXR)/ ultrasound (US) of the liver. Less commonly, a recommended staging evaluation was omitted or the suggested timing of the staging procedure (i.e., pre-operatively versus post-operatively) was not followed. Higher stage and grade of the disease and subsequent chemotherapy administration were associated with higher guideline non-adherence. CONCLUSIONS Low adherence to staging guidelines for newly diagnosed breast cancer according to CCO is shown in a community cancer center. Incorporation of arising prognostic factors to staging procedure determination may increase acceptance and adherence to guidelines in the future.

Abstract
Objective: This study was attempted to investigate overall survival by stage at diagnosis in female breast cancer patients in Northern Thailand by using 2 different staging systems; namely, American Joint Committee on Cancer (AJCC) Tumor (T), Nodal (N) and Metastatic (M) staging system and Surveillance Epidemiology and End Results (SEER) summary staging system. Methods: We studies female breast cancer patients whose data were registered in Chiang Mai cancer registries between January 2006 and December 2015. Data were recorded in SEER summary staging system. The TNM AJCC staging was searched in the medical records. Results: A total of 3,873 female breast cancer patients were diagnosed from 2006-2015. All data sets were recorded in SEER summary stage 2000. Early stage was the most prevalent stage at the time of diagnosis (58%), followed by loco-regional advanced stage (32%), and metastatic breast cancer (10%). The 5-year overall survival rate of early, loco-regional advanced, and metastatic stages were 85.3%, 66.4%, and 26.2%, respectively. After examining the medical records, we excluded patients who had no data on T, N, and M in their records. Finally, only 3,251 patients were analyzed for AJCC stage-specific survival. The 5-year overall survival rate in stages I, II, III, and IV were 94.4%, 85.0%, 56.6%, and 28.3%, respectively. Conclusion: Comparing to more stable economic countries, the 5-year overall survival rate for a specific stage of breast cancer in Northern Thailand was slightly lower in early stage and stage I-II in accordance with AJCC, but much lower in loco-regional stage and stage III with respect to AJCC. Nevertheless, it was similar in metastatic stage and stage IV according to AJCC.

Abstract
OBJECTIVE To compare the clinicopathologic features and survival outcomes of neuroendocrine tumor of the uterine corpus (NET-U) to endometrioid type endometrial carcinoma (EC). METHODS From 1993 to 2012, the Surveillance, Epidemiology and End Results cancer registry was queried for women diagnosed with EC or NET-U. Data regarding stage, grade, presence of extra-uterine disease, lymph node metastasis, receipt of adjuvant radiation, surgical intervention and overall survival (OS) was extracted. Chi-square tests, t-tests and Kaplan Meir curves were used for statistical analysis. RESULTS A total of 98,363 patients were identified: 98,245 with EC and 118 with NET-U. The mean age at diagnosis for EC was 61.7 years and 64.8 years for NET-U (p=0.01). NET-U cases were more likely to be poorly differentiated (97.0% vs. 15.6%; p≤0.01) and have nodal metastasis (56.4% vs. 11.1%; p≤0.01) when compared to EC. Presence of extrapelvic disease at the time of diagnosis was observed more frequently in NET-U compared to EC, 49.1% vs. 4.8%, respectively (odds ratio=18; 95% confidence interval=13.1-27.2; p≤0.01). Significant improvement in OS was observed in NET-U patient who received radiation (OS: 7.7 vs. 3.3 years; p≤0.01) or underwent surgical management (5.6 vs. 0.9 years; p≤0.01). The OS for EC was 14.4 vs. 4.6 years for NET-U (p≤0.01). CONCLUSION NET-U represents an aggressive form of uterine malignancy. When compared to EC, patients with NET-U present at more advanced stage, have more frequent extra-uterine disease and lower OS.

Abstract
OBJECTIVES Computed tomography (CT) examinations are frequent in follow-up care of testicular cancer (TC) but may increase the risk for other cancers. We wanted to assess the actual number of CT and X-ray examinations within the first 5 years after a diagnosis of TC in Israel during 2003-2007. METHODS The database of Maccabi Healthcare Services, Israel, was searched for TC patients diagnosed in 2003 to 2007 by direct linkage with the Israel National Cancer Registry. Data on diagnostic imaging examinations (CT of chest, abdomen, or pelvis, unspecified sites; X-ray of chest) were extracted during a 5-year follow-up for 226 incident patients. The actual number of CT and X-ray examinations was compared to the National Comprehensive Cancer Network (NCCN) guideline. We tabulated the median with 10th and 90th percentiles (P10, P90) for the number of CTs and X-rays considering histology, stage, and adjuvant strategy. RESULTS The number of abdomen or pelvis CTs for TC patients receiving chemo- or radiotherapy was in accordance with the NCCN guideline. The median of abdomen or pelvis CTs for surveillance patients was 8.5 (P10, P90: 3; 13) for nonseminoma and 5.0 (P10, P90: 5; 13) for seminoma patients compared to 14 to 17 CTs recommended. The number of chest X-rays was lower than recommended in the guideline for all adjuvant strategies. CONCLUSIONS The NCCN guidelines regarding CTs were met for TC patients treated with chemo- or radiotherapy but fell below recommendations for surveillance. Guidelines from 2011 and 2012 were updated in favor of fewer CTs during surveillance. KEY POINTS • The number of CTs followed the NCCN guidelines in patients treated with chemo- or radiotherapy. • Surveillance patients received fewer CTs and X-rays than recommended in the NCCN guidelines from 2005. • The number of applied CT examinations corresponded to a radiation dose that did not substantially raise the lifetime risk for cancer.

Abstract
INTRODUCTION The TNM staging system is used globally as the standard for interpreting the extent of cancer. Currently, T3a renal cell carcinoma is classified as tumor extending into the perinephric fat or renal vein. Prognostic outcomes may vary among renal cell carcinomas with renal vein involvement (RVI) versus those with perinephric fat involvement (PFI). MATERIALS AND METHODS We reviewed the medical records of all patients who underwent radical or partial nephrectomy at our institution by a single group of urologists between 2000 and 2014. After identifying those patients with T3a renal cell carcinoma, we further analyzed their prognostic features. Overall and disease-free survival using Kaplan-Meier analysis with log rank comparison was performed among patients with renal vein involvement and PFI. Gender, smoking status, age at diagnosis, body mass index, tumor grade, tumor size, and tumor histology were also analyzed. RESULTS Of 139 patients with T3a renal cell carcinoma, 42 patients were found to have RVI, leaving 97 patients with PFI. Mean follow up was 52.1 months (0.3-183.4) versus 28.8 months (0.3-98.0) for patients with PFI and RVI, respectively. Overall survival (p < 0.048) and disease-free survival (p < 0.049) were significantly lower for patients with RVI. CONCLUSION In our study, patients with T3a renal cell carcinoma that have RVI as opposed to PFI have lower overall and disease-free survival. These findings suggest that patient with T3a renal cell carcinoma with RVI should be monitored more closely than their counterparts with only PFI.

Abstract
The objective was to describe the cervical cancer cases in Brazil by the age-group and stage at diagnosis, and to associate them with the human development index (HDI), where the women live. This was a retrospective study that used data from the Brazilian hospital-based cancer registry from 2005 to 2014. The data were accessed by 5-year age/groups and the federal units. The association between the proportion of cases at Stage I and HDI was estimated in an adjusted linear regression analysis. Among the staged cases, the proportions of cases diagnosed at FIGO Stage I, II, III and IV were 21.2%, 30.7%, 39.9% and 8.2%, respectively. The cases were diagnosed mostly in women aged 45-49 years. There was a significant increase in the proportion of Stage I cases with an increasing HDI (coefficient, 0.46; 95% confidence interval, 0.17-0.76). In conclusion, most of the cases were diagnosed at late stages. The stage at the diagnosis was associated with the human development level. Impact Statement What is already known on this subject? The stage at diagnosis varies according to the level of organisation of the cancer control programme. It is expected that in well-developed programmes there will be a shift to an early stage diagnosis. What the results of this study add? The stage at a diagnosis was associated with the human development level where the women live in Brazil, where most cases were diagnosed at the late stages. What the implications are of these findings for clinical practice and/or further research? This analysis can help with better planning strategies for cancer control. Regional strategies would improve the efficiency of cancer care interventions in countries with large socioeconomic disparities.

Abstract
IMPORTANCE In women with locally advanced cancer of the cervix (LACC), staging defines disease extent and guides therapy. Currently, undetected disease outside the radiation field can result in undertreatment or, if disease is disseminated, overtreatment. OBJECTIVE To determine whether adding fludeoxyglucose F 18 positron emission tomography-computed tomography (PET-CT) to conventional staging with CT of the abdomen and pelvis affects therapy received in women with LACC. DESIGN, SETTING, AND PARTICIPANTS A randomized clinical trial was conducted. Women with newly diagnosed histologically confirmed International Federation of Gynecology and Obstetrics stage IB to IVA carcinoma of the cervix who were candidates for chemotherapy and radiation therapy (CRT) were allocated 2:1 to PET-CT plus CT of the abdomen and pelvis or CT alone. Enrollment occurred between April 2010 and June 2014 at 6 regional cancer centers in Ontario, Canada. The PET-CT scanners were at 6 associated academic institutions. The median follow-up at the time of the analysis was 3 years. The analysis was conducted on March 30, 2017. INTERVENTIONS Patients received either PET-CT plus CT of the abdomen and pelvis or CT of the abdomen and pelvis. MAIN OUTCOMES AND MEASURES Treatment delivered, defined as standard pelvic CRT vs more extensive CRT, ie, extended field radiotherapy or therapy with palliative intent. RESULTS One hundred seventy-one patients were allocated to PET-CT (n = 113) or CT (n = 58). The trial stopped early before the planned target of 288 was reached because of low recruitment. Mean (SD) age was 48.1 (11.2) years in the PET-CT group vs 48.9 (12.7) years in the CT group. In the 112 patients who received PET-CT, 68 (60.7%) received standard pelvic CRT, 38 (33.9%) more extensive CRT, and 6 (5.4%) palliative treatment. The corresponding data for the 56 patients who received CT alone were 42 (75.0%), 11 (19.6%), and 3 (5.4%). Overall, 44 patients (39.3%) in the PET-CT group received more extensive CRT or palliative treatment compared with 14 patients (25.0%) in the CT group (odds ratio, 2.05; 95% CI, 0.96-4.37; P = .06). Twenty-four patients in the PET-CT group (21.4%) received extended field radiotherapy to para-aortic nodes and 14 (12.5%) to common iliac nodes compared with 8 (14.3%) and 3 (5.4%), respectively, in the CT group (odds ratio, 1.64; 95% CI, 0.68-3.92; P = .27). CONCLUSIONS AND RELEVANCE There was a trend for more extensive CRT with PET-CT, but the difference was not significant because the trial was underpowered. This trial provides information on the utility of PET-CT for staging in LACC. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT00895349.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used to relieve postoperative fever, surgery pain, and inflammation. In addition, NSAIDs have anticancer activity and may reduce the risk and mortality of several cancers. However, the association between postoperative NSAIDs and the clinical outcome of non-small cell lung cancer (NSCLC) patients with fever after surgery is not fully understood. We performed a retrospective study of NSCLC patients who underwent surgery between July 2011 and June 2012, aiming to evaluate the effect of postoperative NSAIDs on overall survival (OS) and progression-free survival (PFS). Differences in clinical data between the postoperative NSAIDs group and non-NSAIDs groups were analyzed by Chi-square tests. Kaplan-Meier curves method and Cox regression analysis were conducted for survival analysis. The primary and secondary endpoints were OS and PFS, respectively. This retrospective study included 347 NSCLC patients. There were no significant differences in the clinical characteristics between the NSAIDs group and non-NSAIDs group except for age (P = .024) and differential degree (P = .040). Administration of postoperative NSAIDs was related to longer OS (hazards ratio [HR] 0.528, 95% confidence interval [CI] 0.278-0.884, P = .006) and longer PFS (HR 0.557, 95% CI 0.317-0.841, P = .002) in the multivariate Cox regression model. Subgroup analysis showed statistically significant differences in elderly individuals, male subjects, low smoking index, poor differentiation, and non-adenocarcinoma subgroups, respectively. In conclusion, the administration of postoperative NSAIDs was related to longer OS and PFS in NSCLC patients with postoperative fever.

Abstract
BACKGROUND Colorectal cancer is being diagnosed more frequently in the young and it presents in an advanced stage. In TNM staging, stage depends on tumor size and number of positive nodes, which depend on location of tumor as well as the extent of dissection.The lymph node ratio is regarded as a more reliable marker for prognosis. In this study, we compare epidemiology of colorectal cancer in the young (<40 years) and older patients as well as the LNR. METHODS Patients with colorectal cancer operated at the Tribhuvan University Teaching Hospital, Kathmandu, Nepal for a period of 4 years (2012 - 2016) were included in the study. Patients were grouped into young (? 40 years) and older (> 40 years) and clinic-pathological data such as site of lesion, clinical stage, and lymph node ratio were compared. RESULTS Of the 95 patients of colorectal cancer, 25 patients were of age ? 40 years (26%) and they had a higher median stage at diagnosis. In patients above 40 years, it was diagnosed at a relatively earlier stage. The mean number of positive nodes was 11.64 in younger patients whereas it was 18.34in those more than 40 years of age,but younger patients had higher lymph node ratio than elderly (0.31 vs 0.13) (P-value ? 0.005). CONCLUSIONS Young patients with colorectal cancer tend to have more advanced disease. The lymph node metastasis and lymph node ratio tend to be higher in young patients.

Abstract
BACKGROUND The worldwide incidence of cutaneous melanoma (CM) has been continuously increasing over the last decades. Primary and secondary prevention, with attention to risk factors and early diagnosis, remain the cornerstone for reducing the burden of cutaneous melanoma. Detailed information with respect to clinical and pathological data on cutaneous melanoma is scarce in Brazil. OBJECTIVE The purpose of our study was to analyze epidemiological and pathological characteristics of primary cutaneous melanoma in Joinville, southern Brazil. METHODS Observational, cross-sectional, retrospective study in which 893 reports of primary cutaneous melanoma from the local population were analyzed in the period 2003-2014. The study was approved by the local Ethics and Research Committee. RESULTS We observed a female predominance of cutaneous melanoma (56.3%). The age standardized incidence rate of primary cutaneous melanoma for the world population in the period 2003-06 was 11.8 per 100,000 population (CI 95%, 10.3-13.4), and 17.5 (CI 95%, 15.7-19.3) in 2011-14, revealing a significant increase of 48.3% (p < 0,05). Six and a half percent of patients had multiple cutaneous melanomas (mean 2.2 years and a maximum of 10.0 years between diagnoses). We observed significant differences between the location head/neck and cutaneous melanoma in situ, lower limb with Breslow depth S III and upper limb with Breslow depth S I. The comparison of the characteristics of cutaneous melanoma in the elderly and non-elderly (< 60 years old) showed significant differences with respect to all the variables studied. STUDY LIMITATIONS Using secondary data source. CONCLUSION Joinville has high incidence coefficients for Brazilian standards, showing an increase in the incidence of cutaneous melanoma.

Abstract
Rectal cancer is one of the common cancers which poses a threat to the health of mankind. In recent years. Multi-modality treatment strategies for locally advanced rectal cancer improve the treatment efficiency. Accurate prediction of the treatment response after the neoadjuvant chemoradiotherapy (CRT) can guide more suitable treatment strategy. MERCURY study proved the prognostic value of post-CRT standard morphologic MRI(T2-weighted) assessment of tumor regression grade(TRG), and MRI assessment of circumferential resection margin can guide the definitive surgery. Compared with standard morphologic MRI (T2-weighted), functional MRI, including diffusion weighted imaging (DWI) and dynamic contrast enhanced (DCE) MRI, has shown more promising results for the prediction of therapeutic response in rectal cancer. The addition of diffusion-weighted images to T2-weighted images improves the accuracy of restaging examinations for determination of complete pathologic responders. DCE can reflect the tumor micro-vascular environment, and the change of perfusion in response to treatment. These images have the potential to improve the accuracy of therapeutic response in rectal cancer.

Abstract
OBJECTIVE To evaluate the clinical significance of No.12 lymph node dissection for advanced gastric cancer with D2 lymphadenectomy. METHODS Clinicopathologic data and No.12 lymph node dissection of 256 advanced gastric cancer patients undergoing radical operation in our department between January 2005 and December 2010 were retrospectively summarized and the influence factors of metastasis in No.12 lymph nodes were analyzed. RESULTS Of 256 patients, 179 were male and 77 were female with the average age of 59.2 years. Tumor located in the upper of stomach in 24 cases, middle of stomach in 41 cases, lower of stomach in 174 cases, multi-focus or diffuse distribution of stomach in 17 cases. Tumor diameter was <3 cm in 39 cases, 3 to 5 cm in 100 cases, >5 cm in 117 cases. Serum carcinoembryonic antigen (CEA) level increased in 61 cases, serum carbohydrate antigens (CA)72-4 increased in 56 cases and CA19-9 increased in 61 cases. The number of No.12 lymph nodes resected from all the patients was 1 152, and the average number was 4.5±1.9. The metastasis rate of No.12 lymph nodes was 9.4%(24/256) after hematoxylin eosin staining (positive group). All the patients received effective follow-up to December 2015, and the average follow-up time was 101.2 months. The median survival time of positive No.12 group (24 cases) was 29.8 months and of negative No.12 group (232 cases) was 78.2 months, whose difference was statistically significant (χ2=21.715, P=0.000). Univariate analysis found that No.12 lymph node metastasis was not associated with age, gender, tumor differentiation (all P>0.05), but was associated with tumor location, tumor diameter, invasive depth (all P<0.05), and was closely associated with Borrmann type, outside metastatic lymph nodes of No.12 and high levels of serum CEA, CA72-4 and CA19-9 (all P=0.000). Multivariate regression analysis found that tumor location (RR=2.452, 95%CI:1.537 to 3.267, P=0.000), Borrmann type (RR=1.864, 95%CI:1.121 to 3.099, P=0.016) and number of outside metastatic lymph nodes of No.12 (RR=2.979, 95%CI: 2.463 to 3.603, P=0.000) were the independent risk factors of the No.12 metastasis (P<0.05). CONCLUSIONS Metastasis in No.12 lymph nodes indicates poorer prognosis. The No.12 lymph nodes of advanced gastric cancer patients with curative resection, especially those with the tumor located in the lower part, Borrmann type IIII(, outside metastatic lymph nodes of No.12, should be regularly cleaned.

Abstract
OBJECTIVE To analyze relationships between the tumor deposits (TD) and clinicopathologic features of gastric cancer and investigate the value of TD in staging and prognosis in gastric cancer patients. METHODS Retrospective cohort study was conducted to evaluate the clinicopathologic data of 388 gastric cancer patients who underwent surgical procedures in Chinese PLA General Hospital between November 2011 and December 2012. Relationships between TD and clinicopathologic features were analyzed by χ2 or Fisher exact tests. Survival curves were also generated by Kaplan-Meier method. The univariate and multivariate analysis were performed with Log-rank and COX proportional hazard model to examine the association between prognosis and TD. RESULTS TD were observed in 67 (17.3%) of 388 gastric cancer patients, including 48 male patients (48/289, 16.6%) and 19 female patients (19/99, 19.2%). There were 40 patients (40/198, 20.2%) whose age was above 64 years old. TNM staging of positive TD patients was as follows: for pathology, there were 5 patients (5/64, 7.8%) in stage II(b, 6 patients (6/58, 10.3%) in stage III(a, 14 patients (14/75, 18.7%) in stage III(b, 30 patients (30/135, 22.2%) in stage III(c, 12 patients (12/39, 30.8%) in stage IIII( and no one in stage I(b or II(a; for T-staging, there were 2 patients (2/18, 11.1%) in stage T2, 2 patients (2/27, 7.4%) in stage T3, 36 patients (36/259, 13.9%) in stage T4a and 27 patients (27/84, 32.1%) in stage T4b; for N-stage, there were 5 patients (5/72, 6.9%) in stage N0, 6 patients (6/72, 8.3%) in stage N1, 19 patients (19/82, 23.2%) in stage N2, 27 patients (27/100, 27.0%) in stage N3a and 10 patients(10/62, 16.1%) in stage N3b; for M-stage, there were 12 patients (12/40, 30.0%) in distal metastases; for vascular invasion, there were 29 patients (29/129, 22.5%). Among positive TD patients, the number of TD >3 was found in 38 of 67 cases(56.7%). TD was associated with pTNM-stage (χ2=16.898, P=0.010), T-stage (χ2=17.382, P=0.001), N-stage (χ2=18.080, P=0.001), M-stage (χ2=5.060, P=0.036) and vascular invasion(χ2=3.675, P=0.039). The median survival time of positive TD patients was significantly shorter as compared to negative TD patients (22 months vs. 32 months, χ2=23.391, P=0.012). Among positive TD patients, the median survival time of patients with TD number >3 was significantly shorter as compared to those with TD number <3 (17 months vs. 25 months, χ2=5.157, P=0.023). Multivariate survival analysis showed that TD number >3 was the independent risk factor of prognosis (RR=2.350, 95%CI:1.345 to 4.106, P=0.003). CONCLUSIONS TD state is closely associated with the staging of gastric cancer and TD number >3 indicates a poor prognosis.

Abstract
OBJECTIVE To explore the risk factors and prognosis of No.8p lymph node metastasis in cases with advanced gastric cancer. METHODS Clinicopathological and follow-up data of 790 cases with advanced gastric cancer undergoing gastrectomy (including No.8p lymphadenectomy) from October 2003 to October 2013 in Fujian Provincial Tumor Hospital were analyzed retrospectively. Patients receiving neoadjuvant chemotherapy were excluded. Associations of No.8p lymph node metastasis with clinicopathological characteristics and metastasis in other regional lymph node were analyzed. Prognostic difference between positive No.8p group and negative No.8p group was examined. RESULTS Positive No.8p lymph node was found in 93 cases (11.8%) among 790 cases with advanced gastric cancer. Univariate analysis showed that gender [male 9.8%(56/572) vs. female 17.0%(37/218), P=0.005], preoperative CEA level [<5 μg/L 28.0%(61/218) vs. ≥5 μg/L 5.6%(32/572), P=0.005], tumor size[diameter <5 cm 3.8%(13/346) vs. ≥5 cm 18.0%(80/445), P=0.000], tumor location [gastric fundus and cardiac 10.7% (26/244) vs. gastric body 13.5% (30/222) vs. gastric antrum 10.1% (31/308) vs. total gastric 37.5%(6/16), P=0.007], Borrmann staging [type II( 1.9%(4/211) vs. type III( 11.6% (54/464) vs. type IIII( 30.4%(35/115), P=0.000], tumor differentiation [high 0/8 vs. moderate 6.7%(25/372) vs. low 16.6%(68/410), P=0.000], T staging [T2 2.4%(4/170) vs. T3 13.1%(35/267) vs. T4 15.3%(54/353), P=0.000], N staging [N0 0 (0/227) vs. N1 2.2%(5/223) vs. N2 15.2%(26/171) vs. N3 36.7%(62/169), P=0.000] were closely associated with the No.8p lymph node metastasis. Multivariate analysis that revealed gender (OR=1.762, 95%CI: 1.020-3.043), tumor size (OR=1.107, 95%CI: 1.020-1.203), N staging (OR=4.093, 95%CI: 2.929-5.718), tumor differentiation (OR=1.782, 95%CI:1.042-3.049), and metastasis in No.8a(OR=5.370, 95%CI: 3.425-8.419), No.3(OR=1.127, 95%CI:1.053-1.206), No.6(OR=1.221,95%CI: 1.028-1.450), No.7(OR=2.149, 95%CI: 1.711-2.699), No,11p(OR=2.085, 95%CI: 1.453-2.994), No.14v(OR=2.604, 95%CI: 1.038-6.532) group lymph nodes were the independent risk factors of No.8p lymph node metastasis. One-year, 3-year and 5-year survival rates in positive No.8p group were 85.7%, 47.5% and 22.6%, and those in negative No.8p group were 96.2%, 82.5% and 70.3% respectively, whose differences were significant (χ2=109.767, P<0.05). CONCLUSIONS Metastasis in Np.8p lymph nodes is an important factor affecting the prognosis of patients with advanced gastric cancer. In patients with female gender, tumor diameter ≥5 cm, preoperative late N staging, low tumor differentiation or metastasis in No.8a, No.3, No.6, No.7, No.11p, No.14v group lymph nodes, thorough clean rance of No.8p group lymph node should be considered.

Abstract
Gastric cancer (GC) is one of the most common tumor in the world, and remains a major public health problem and one of the leading causes of death. Recently many researches have demonstrated that systemic inflammatory response is associated with prognosis and response to therapy in gastric cancer, and the peripheral blood count test can partly reflect the systemic inflammatory response. Based on the peripheral blood count test, there are a lot of research regarding the relation between the platelet count (PLT), neutrophil, lymphocyte, white blood cell (WBC), neutrophil to lymphocyte ratio(NLR), platelet to lymphocyte ratio (PLR) with their prognostic role in gastric cancer. A high PLT and preoperative lymphocytopenia are both associated with increased lymph node metastasis, stage (III(+IIII(), serosal invasion (T3+T4) risk and poorer overall survival. Besides above, platelet monitoring following surgery can be applied to predict the recurrence for patients with GC that suffer preoperative high PLT but have restored PLT levels following resection. Moreover systemic inflammatory factors based on blood parameters, such as PLR, NLR and so on, have relation with the poor prognosis of patients with GC. Among them, high NLR is a negative predictor of prognosis in GC patients. However PLR remains inconsistent, while most researches demonstrated high PLR may be useful prognostic factor rather than independent prognostic factor. There are still some limitations which include various cut-off values, little of clinician attention, the uncertain mechanism, etc. Here we review the research progress in the prognostic role of the blood count test in gastric cancer.

Abstract
OBJECTIVE To investigate the clinicopathological characteristics, diagnosis, treatment and prognosis of patients with primary gastric adenosquamous cell carcinoma. METHODS A total of 5 562 patients with gastric neoplasm were admitted in Tianjin Medical University Cancer Institute and Hospital from January 2001 to January 2011. Among them 42 patients were diagnosed as primary gastric adenosquamous cell carcinoma, accounting for 0.76% of all the patients. The clinicopathological and follow-up data of these 42 patients with primary gastric adenosquamous cell carcinoma were retrospectively analyzed, and Cox proportional hazard model was used to analyze the prognostic factors of gastric adenocarcinoma squamous cell carcinoma. RESULTS Among above 42 patients, 32 were male and 10 were female, with a male-to-female ratio of 3.2/1.0 and the average age was 63 years (range: 46 to 77 years). Five patients (11.9%) were confirmed as adenosquamous cell carcinoma by preoperative pathological examination, while other 37 patients were diagnosed as adenocarcinoma preoperatively. According to the 7th edition AJCC TNM classification system for gastric adenocarcinoma, 5 patients (11.9%) were in stage II(, 30 patients (71.4%) in stage III( and 7 patients (16.7%) in stage IIII(. The maximum tumor diameter was > 5 cm in 18 patients (42.9%). Borrmann type III(-IIII( was found in 29 patients (69.0%), and poorly differentiated (or undifferentiated) tumor was found in 32 patients (76.2%). Radical operations were performed in 31 patients (73.8%), the reasons of non radical operations included infiltration of pancreas in 3 patients, infiltration of radices mesocili transvers in 1 patient and classification of stage IIII( in 7 patients. Lymph node dissection was performed in 37 patients, 83.8% of them (31/37) was found with lymphatic metastases. Twenty-five patients received adjuvant chemotherapy except for 7 patients in stage IIII( and 10 patients who refused adjuvant chemotherapy. All the patients had an average survival time of 36.4 months and median survival time of 28.0 months, and the overall 1-, 3- and 5-year survival rates were 82.2%, 42.3% and 18.2% respectively. Univariate analysis revealed that tumor size (χ2=4.039, P=0.044), Borrmann type (χ2=18.728, P=0.000), tumor differentiation (χ2=19.612, P=0.000), radical gastectomy (χ2=41.452, P=0.000), lymph node metastasis (χ2=9.689, P=0.002) and clinical stage (χ2=26.277, P=0.000) were associated with postoperative survival. Multivariate analysis revealed that tumor differentiation (HR=10.560, 95%CI:2.263-49.281, P=0.003), radical gastrectomy (HR=4.309, 95%CI:1.311-14.168, P=0.016) and clinical stage (HR=2.392, 95%CI:1.022-5.600, P=0.044) were independent prognosis factors. CONCLUSIONS Primary gastric adenosquamous cell carcinoma is rare with poor prognosis. Radical gastrectomy is recommended. Tumor differentiation, radical gastrectomy and clinical stage are important indicators to evaluate prognosis of primary gastric adenosquamous cell carcinoma.

Abstract
OBJECTIVE To investigate the prognostic factors of patients with lymph node-negative metastasis gastric cancer (pN0). METHODS Clinicopathological data of patients with pN0 gastric cancer who underwent radical operation at the Department of Surgical Oncology, The First Hospital of China Medical University from May 1980 to August 2012 were collected and analyzed retrospectively. INCLUSION CRITERIA (1) Patients were diagnosed as gastric adenocarcinoma; (2) Postoperative pathology confirmed T1a to 4bN0M0 gastric cancer; (3) Total number of harvested lymph node was more than 15. The patients, who died within 1 month after the operation, died of other diseases, had remnant gastric cancer, or had incomplete follow-up data, were excluded. Univariate analysis was used to analyze the clinical factors that may influence the prognosis of patients with stage pN0 gastric cancer, then, those significant variables were entered into the Cox's proportional hazards regression model for multivariate analysis to obtain the independent prognostic factors for patients with pN0 gastric cancer finally. Furthermore, the prognosis of patients with pN0 advanced gastric cancer (invasive depth ≥ T2) were analyzed using the same method. RESULTS A total of 610 patients with pN0 gastric cancer were enrolled in the study, including 441 males and 169 females with age ranging from 19 to 83 (mean 56.4±11.0) years, D1 lymph node dissection in 45 cases, D2 lymph node dissection in 543 cases, D3 lymph node dissection in 22 cases, and 384 cases of advanced gastric cancer. The overall followed-up was 1 to 372 (median 32) months. Ninety cases (14.8%) were dead during the follow-up. The median survival was 277.7(95%CI: 257.6 to 297.8) months, and the 1-, 3-, 5-year survival rates were 96.5%, 87%, 83.2%. Univariate analysis showed that tumor diameter, depth of invasion, gross type, lymph node dissection and lymph vessel cancer embolus were related to the prognosis (all P<0.05). The 5-year survival rate of patients with tumor diameter >4 cm was significantly lower than those with tumor diameter ≤4 cm (75.6% vs. 87.8%, P=0.000). The 5-year survival rates of T1a, T1b, T2, T3 and T4 were 98.4%, 92.8%, 84.2%, 61.0% and 31.4% respectively, and the difference was statistically significant (P=0.000). In gross type, 5-year survival rate of early gastric cancer was 96.0%, and of Borrmann I( to IIII( type gastric cancer was 100%, 83.4%, 73.7% and 68.9% respectively, whose difference was statistically significant(P=0.000). The 5-year survival rates in patients undergoing lymph node dissection D1, D2 and D3 were 100%, 83.3% and 58.7%, and the difference was significant (P=0.005). The 5-year survival rate of patients with positive lymphatic cancer embolus was lower than those with negative ones (69.4% vs. 86.9%, P=0.000). Multivariate analysis showed that the gross type [Borrmann II(/early gastric cancer: HR(95% CI)=15.129(3.284 to 69.699), Borrmann III(/early gastric cancer: HR(95% CI)=14.613 (3.292 to 64.875), Borrmann IIII(/early gastric cancer: HR (95% CI)=15.430 (2.778 to 85.718),Borrmann IIIII(/early gastric cancer: HR(95%CI)=12.604 (1.055 to 150.642), P=0.025] and the positive lymphatic cancer embolus [HR(95% CI)=3.241 (2.056 to 5.108), P=0.000] were the independent prognostic factors of patients with pN0 gastric cancer. For pN0 patients with advanced gastric cancer, multivariate analysis showed that the depth of invasion [stage T3/stage T2: HR(95%CI)=1.520 (0.888 to 2.601), stage T4/stage T2: HR(95%CI)=2.235(1.227 to 4.070); P=0.031] and the positive lymphatic cancer embolus [HR(95%CI)=3.065 (1.930 to 4.868); P=0.000] were the independent risk factors influencing the prognosis. CONCLUSIONS Positive lymphatic cancer embolus and worse gross pattern indicate poorer prognosis of patients with pN0 gastric cancer, which may be used as effective markers in evaluating the prognosis. As for pN0 advanced gastric cancer, invasion depth and positive lymphatic cancer embolus can play a more important role in the prediction.

Abstract
OBJECTIVE To investigate the association of peripheral nerve invasion (PNI) with clinicopathological factors and prognosis of colorectal cancer. METHODS Clinicopathological data and Surgical specimens of 372 colorectal cancer patients who underwent radical resection from January 2011 to June 2012 in The Second Affiliated Hospital of Harbin Medical University were collected. Histopathological evaluation of tissue samples was conducted with hematoxylin and eosin-stained sections. PNI was considered positive when cancer cells were observed inside the nerve sheath, or when at least 33% of the nerve periphery was surrounded by cancer cells. The relationship between PNI and clinicopathological factors of colorectal cancer was analyzed by χ2 test or Fisher's exact test. Three-year overall survivals of PNI positive and negative patients were determined using the Kaplan-Meier method. Detection results were compared using log-rank test. RESULTS Of 372 colorectal cancer patients, 133 (35.8%) were PNI positive. Among the PNI positive patients, 63 cases were male and 70 cases female; 76 cases were more than 60 years old and 57 cases less than 60 years old; tumors of 6 cases located in the ileocecal colon, of 33 cases in the ascending colon, of 7 cases in the transverse colon, of 8 cases in the descending colon, of 22 cases in the sigmoid colon, and of 57 cases in the rectum; tumor diameter was greater than 4 cm in 83 cases, and less than 4 cm in 50 cases; tumors of 48 cases were moderately or highly differentiated, and of 85 cases poorly-differentiation; tumor invasion depth in 2 cases, T2 in 7 cases, T3 in 93 cases, T4 in 31 cases; lymphatic metastasis was N0 phase in 56 cases, N1 in 41 cases, and N2 in 36 cases; tumors were stage I( in 2 cases, stage II( in 40 cases, of stage III( in 75 cases and stage IIII( in 16 cases. The positive rate of PNI was significantly associated with tumor location (χ2=11.20, P=0.048), tumor size (χ2=21.80, P=0.000), differentiation (χ2=60.90, P=0.000), depth of invasion (χ2=19.00, P=0.000), lymph node metastasis (χ2=19.70, P=0.000) and TNM staging (χ2=70.80, P=0.000), but not with sex, age or vascular invasion(P>0.05). The median follow-up time was 48 (8 to 62) months. Kaplan-Meier survival curve showed that the 3-year survival rate of PNI positive patients was 52.6%, significantly lower than that of PNI negative patients(78.3%, P=0.000). Further analysis of patients with stage II( and III( colorectal cancer showed that the 3-year survival rates of PNI positive patients were 62.3% and 43.5%, respectively, which were significantly lower than those of PNI negative patients with stage II( and III((91.7% and 79.4%), and the differences were statistically significant(P=0.000). CONCLUSIONS PNI is a poor prognostic factor of colorectal cancer. It may be a complement of the classic TNM staging classification in stratifying colorectal cancer patients, especially in stages II( and III(.
