Abstract
BACKGROUND National Comprehensive Cancer Network guideline adherence improves cancer outcomes. In rectal cancer, guideline adherence is distributed differently by race/ethnicity, socioeconomic status, and insurance. OBJECTIVE This study aimed to determine the independent effects of race/ethnicity, socioeconomic status, and insurance status on rectal cancer survival after accounting for differences in guideline adherence. DESIGN This was a retrospective study. SETTINGS The study was conducted using the California Cancer Registry. PATIENTS This study included patients aged 18 to 79 years diagnosed with rectal adenocarcinoma between January 1, 2004, and December 31, 2017, with follow-up through November 30, 2018. Investigators determined whether patients received guideline-adherent care. MAIN OUTCOME MEASURES ORs and 95% CIs were used for logistic regression to analyze patients receiving guideline-adherent care. Disease-specific survival analysis was calculated using Cox regression models. RESULTS A total of 30,118 patients were examined. Factors associated with higher odds of guideline adherence included Asian and Hispanic race/ethnicity, managed care insurance, and high socioeconomic status. Asians (HR, 0.80; 95% CI, 0.72-0.88; p < 0.001) and Hispanics (HR, 0.91; 95% CI, 0.83-0.99; p = 0.0279) had better disease-specific survival in the nonadherent group. Race/ethnicity were not factors associated with disease-specific survival in the guideline adherent group. Medicaid disease-specific survival was worse in both the nonadherent group (HR, 1.56; 95% CI, 1.40-1.73; p < 0.0001) and the guideline-adherent group (HR, 1.18; 95% CI, 1.08-1.30; p = 0.0005). Disease-specific survival of the lowest socioeconomic status was worse in both the nonadherent group (HR, 1.42; 95% CI, 1.27-1.59) and the guideline-adherent group (HR, 1.20; 95% CI, 1.08-1.34). LIMITATIONS Limitations included unmeasured confounders and the retrospective nature of the review. CONCLUSIONS Race, socioeconomic status, and insurance are associated with guideline adherence in rectal cancer. Race/ethnicity was not associated with differences in disease-specific survival in the guideline-adherent group. Medicaid and lowest socioeconomic status had worse disease-specific survival in both the guideline nonadherent group and the guideline-adherent group.

EFECTOS DIFERENCIALES DE LA RAZA, EL NIVEL SOCIOECONMICO COBERTURA SOBRE LA SUPERVIVENCIA ESPECFICA DE LA ENFERMEDAD EN EL CNCER DE RECTO ANTECEDENTES: El cumplimiento de las guías de la National Comprehensive Cancer Network mejora los resultados del cáncer. En el cáncer de recto, el cumplimiento de las guías se distribuye de manera diferente según la raza/origen étnico, nivel socioeconómico y el cobertura médica.OBJETIVO: Determinar los efectos independientes de la raza/origen étnico, el nivel socioeconómico y el estado de cobertura médica en la supervivencia del cáncer de recto después de tener en cuenta las diferencias en el cumplimiento de las guías.DISEÑO: Este fue un estudio retrospectivo.ENTORNO CLINICO: El estudio se realizó utilizando el Registro de Cáncer de California.PACIENTES: Pacientes de 18 a 79 años diagnosticados con adenocarcinoma rectal entre el 1 de enero de 2004 y el 31 de diciembre de 2017 con seguimiento hasta el 30 de noviembre de 2018. Los investigadores determinaron si los pacientes recibieron atención siguiendo las guías.PRINCIPALES MEDIDAS DE RESULTADO: Se utilizaron razones de probabilidad e intervalos de confianza del 95 % para la regresión logística para analizar a los pacientes que recibían atención con adherencia a las guías. El análisis de supervivencia específico de la enfermedad se calculó utilizando modelos de regresión de Cox.RESULTADOS: Se analizaron un total de 30.118 pacientes. Los factores asociados con mayores probabilidades de cumplimiento de las guías incluyeron raza/etnicidad asiática e hispana, seguro de atención administrada y nivel socioeconómico alto. Los asiáticos e hispanos tuvieron una mejor supervivencia específica de la enfermedad en el grupo no adherente HR 0,80 (95 % CI 0,72 - 0,88, p < 0,001) y HR 0,91 (95 % CI 0,83 - 0,99, p = 0,0279). La raza o el origen étnico no fueron factores asociados con la supervivencia específica de la enfermedad en el grupo que cumplió con las guías. La supervivencia específica de la enfermedad de Medicaid fue peor tanto en el grupo no adherente HR 1,56 (IC del 95 % 1,40 - 1,73, p < 0,0001) como en el grupo adherente a las guías HR 1,18 (IC del 95 % 1,08 - 1,30, p = 0,0005). La supervivencia específica de la enfermedad del nivel socioeconómico más bajo fue peor tanto en el grupo no adherente HR 1,42 (IC del 95 %: 1,27 a 1,59) como en el grupo adherente a las guías HR 1,20 (IC del 95 %: 1,08 a 1,34).LIMITACIONES: Las limitaciones incluyeron factores de confusión no medidos y la naturaleza retrospectiva de la revisión.CONCLUSIONES: La raza, el nivel socioeconómico y cobertura médica están asociados con la adherencia a las guías en el cáncer de recto. La raza/etnicidad no se asoció con diferencias en la supervivencia específica de la enfermedad en el grupo que cumplió con las guías. Medicaid y el nivel socioeconómico más bajo tuvieron peor supervivencia específica de la enfermedad tanto en el grupo que no cumplió con las guías como en los grupos que cumplieron.

Abstract
PURPOSE Although participation in multidisciplinary tumor boards (MTBs) is an obligatory quality criterion for certification, there is scarce evidence, whether MTB recommendations are consistent with consensus guidelines and whether they are followed in clinical practice. Reasons of guideline and tumor board deviations are poorly understood so far. METHODS MTB's recommendations from the weekly MTB for gastrointestinal cancers at the University Cancer Center Leipzig/Germany (UCCL) in 2020 were analyzed for their adherence to therapy recommendations as stated in National German guidelines and implementation within an observation period of 3 months. To assess adherence, an objective classification system was developed assigning a degree of guideline and tumor board adherence to each MTB case. For cases with deviations, underlying causes and influencing factors were investigated and categorized. RESULTS 76% of MTBs were fully adherent to guidelines, with 16% showing deviations, mainly due to study inclusions and patient comorbidities. Guideline adherence in 8% of case discussions could not be determined, especially because there was no underlying guideline recommendation for the specific topic. Full implementation of the MTBs treatment recommendation occurred in 64% of all cases, while 21% showed deviations with primarily reasons of comorbidities and differing patient wishes. Significantly lower guideline and tumor board adherences were demonstrated in patients with reduced performance status (ECOG-PS ≥ 2) and for palliative intended therapy (p = 0.002/0.007). CONCLUSIONS The assessment of guideline deviations and adherence to MTB decisions by a systematic and objective quality assessment tool could become a meaningful quality criterion for cancer centers in Germany.

Abstract
PURPOSE We analyzed adherence to the National Comprehensive Cancer Network treatment guidelines for anal squamous cell carcinoma in California and the associated impacts on survival. METHODS This was a retrospective study of patients in the California Cancer Registry aged 18 to 79 years with recent diagnoses of anal squamous cell carcinoma. Predefined criteria were used to determine adherence. Adjusted odds ratios and 95% confidence intervals were estimated for those receiving adherent care. Disease-specific survival (DSS) and overall survival (OS) were examined with a Cox proportional hazards model. RESULTS 4740 patients were analyzed. Female sex was positively associated with adherent care. Medicaid status and low socioeconomic status were negatively associated with adherent care. Non-adherent care was associated with worse OS (Adjusted HR 1.87, 95% CI = 1.66, 2.12, p < 0.0001). DSS was worse in patients receiving non-adherent care (Adjusted HR 1.96, 95% CI = 1.56, 2.46, p < 0.0001). Female sex was associated with improved DSS and OS. Black race, Medicare/Medicaid, and low socioeconomic status were associated with worse OS. CONCLUSIONS Male patients, those with Medicaid insurance, or those with low socioeconomic status are less likely to receive adherent care. Adherent care was associated with improved DSS and OS in anal carcinoma patients.

Abstract
BACKGROUND Merkel cell carcinoma (MCC) is an aggressive neuroendocrine carcinoma of the skin. Our report describes the evolution of management and characteristics associated with recurrence, disease-specific survival (DSS) and overall survival (OS) in the treatment of MCC. METHODS A single institution retrospective review of MCC and SEER data to determine factors associated with RFS, DSS, and OS using a multivariable Cox regression on inverse-probability weighted cohorts. RESULTS One hundred fifty-nine patients were identified with a median age of 75. Of these, 96% were Caucasian and 60% male. Fifty-eight out of 159 (36%) of all patients were deceased with 21/58 (36%) dead from MCC with a median follow-up of 3.1 years. Institutionally, trends over time demonstrated an increased use of immunotherapy with a concomitant decrease in chemotherapy and decreased use of radiotherapy alone. Institutionally and nationally, there has been increased surgical nodal staging. Institutionally, factors associated with shorter DSS included advanced age, active cigarette smoker (p = 0.002), cT2 disease (p = 0.007), and MCC with unknown primary (p < 0.001). Institutionally, factors associated with shorter OS included ages ≥ 75 years (p < 0.001), an immunocompromised state (p < 0.001), truncal primary site (p = 0.002), and cT2 disease (HR 9.59, p < 0.001). CONCLUSION Changing practice patterns in MCC management have been driven by the adoption of immunotherapy. Our study highlights that competing risks of mortality in MCC patients likely prevents OS from being an accurate surrogate outcome measure to understand factors associated with DSS.

Abstract
BACKGROUND The National Comprehensive Cancer Network has defined metrics for colorectal cancer; however, the association of metric adherence with patient clinical outcomes remains underexplored. The study aim was to evaluate the association of National Comprehensive Cancer Network metric adherence with recurrence and mortality in Veterans with nonmetastatic colorectal cancer. METHODS Veterans with stage I-III colorectal cancer who underwent non-emergent resection from 2001 to 2015 at a single Veterans Affairs Medical Center were included. The primary predictor was completion of eligible National Comprehensive Cancer Network metrics. The primary outcome was a composite of recurrence or all-cause death in three phases of care: surgical (up to 6 months after resection), treatment (6-18 months after resection), and surveillance (18 months-3 years after resection). Hazard ratios were estimated via Cox proportional hazards regression in a propensity score-weighted cohort. RESULTS A total of 1107 electronic medical records of patients undergoing colorectal surgery were reviewed, and 379 patients were included (301 colon and 78 rectal cancer). In the surgical phase, the weighted analysis yielded a hazard ratio of 0.37 (95% confidence interval 0.12-1.13) for metric-adherent patients compared with non-adherent patients. In the treatment and surveillance phases, the hazard ratios for metric-adherent care were 0.68 (95% confidence interval 0.25-1.85) and 0.91 (95% confidence interval 0.31-2.68), respectively. CONCLUSIONS The National Comprehensive Cancer Network guideline metric adherence was associated with a lower rate of recurrence and death in the surgical phase of care among stage I-III patients with resected colorectal cancer.

Abstract
Background The effects of adjuvant chemotherapy in patients with stage II colorectal cancer (CRC) has been in controversy for a long time. Our study aimed to find an effective inflammatory marker to predict the effects of chemotherapy. Methods Seven hundred eight stage II CRC patients in our institution were included. The subpopulation treatment effect pattern plot (STEPP) analysis was used to determine the optimal inflammatory marker and cut-off value. Propensity score matching (PSM) was performed to balance discrepancy between the chemotherapy and non-chemotherapy group. Survival analyses based on overall survival (OS) and cancer-specific survival (CSS) were performed with Kaplan-Meier methods with log-rank test and Cox proportional hazards regression. The restricted mean survival time (RMST) was used to measure treatment effect. Results The platelet to lymphocyte ratio (PLR) was chosen as the optimal marker with a cut-off value of 130 according to STEPP. In OS analysis, PLR was significantly associated with the effects of chemotherapy (interaction p = 0.027). In the low-PLR subgroup, the chemotherapy patients did not have a longer OS than the non-chemotherapy patients (HR: 0.983, 95% CI: 0.528–1.829). In the high-PLR subgroup, the chemotherapy patients had a significantly longer OS than the non-chemotherapy patients (HR: 0.371, 95% CI: 0.212–0.649). After PSM, PLR was still associated with the effects of chemotherapy. In CSS analysis, PLR was not significantly associated with the effects of chemotherapy (interaction p = 0.116). In the low-PLR subgroup, the chemotherapy patients did not have a longer CSS than the non-chemotherapy patients (HR: 1.016, 95% CI: 0.494–2.087). In the high-PLR subgroup, the chemotherapy patients had a longer CSS than the non-chemotherapy patients (HR: 0.371, 95% CI: 0.212–0.649). After PSM, PLR was not associated with the effects of chemotherapy. Conclusions PLR is an effective marker to predict the effects of chemotherapy in patients with stage II CRC.

Abstract
OBJECTIVE To evaluate the association of race-ethnicity and neighborhood socioeconomic status with adherence to National Comprehensive Cancer Network guidelines for endometrial carcinoma. METHODS Data are from the SEER (Surveillance, Epidemiology, and End Results) cancer registry of women diagnosed with endometrial carcinoma for the years 2006-2015. The sample included 83,883 women after inclusion and exclusion criteria were applied. Descriptive statistics, bivariate analyses, univariate, and multivariate logistic regression models were performed to evaluate the association between race-ethnicity and neighborhood socioeconomic status with adherence to treatment guidelines. RESULTS After controlling for demographic and clinical covariates, Black (odds ratio [OR] 0.89, P<.001), Latina (OR .92, P<.001), and American Indian or Alaska Native (OR 0.82, P=.034) women had lower odds of receiving adherent treatment and Asian (OR 1.14, P<.001) and Native Hawaiian or Pacific Islander (OR 1.19 P=.012) women had higher odds of receiving adherent treatment compared with White women. After controlling for covariates, there was a gradient by neighborhood socioeconomic status: women in the high-middle (OR 0.89, P<.001), middle (OR 0.84, P<.001), low-middle (OR 0.80, P<.001), and lowest (OR 0.73, P<.001) neighborhood socioeconomic status categories had lower odds of receiving adherent treatment than the those in the highest neighborhood socioeconomic status group. CONCLUSIONS Findings from this study suggest there are racial-ethnic and neighborhood socioeconomic disparities in National Comprehensive Cancer Network treatment adherence for endometrial cancer. Standard treatment therapies should not differ based on sociodemographics. Interventions are needed to ensure that equitable cancer treatment practices are available for all individuals, regardless of racial-ethnic or socioeconomic background.

Abstract
Colon cancer is the second leading cause of cancer-related mortality worldwide, and the prognosis of advanced colon cancer has remained poor in recent years. Galectin-9 (Gal-9) is a tandem-repeat type galectin that has recently been shown to exert antiproliferative effects on various types of cancer cells. The present study aimed to assess the effects of Gal-9 on human colon and colorectal cancer cells in vitro and in vivo, as well as to evaluate the microRNAs (miRNAs/miRs) associated with the antitumor effects of Gal-9. We examined the ability of Gal-9 to inhibit cell proliferation via apoptosis, and the effects of Gal-9 on cell cycle-related molecules in various human colon and colorectal cancer cell lines. In addition, Gal-9-mediated changes in activated tyrosine kinase receptors and angiogenic molecules were assessed using protein array chips in colon and colorectal cancer cells. Moreover, miRNA array analysis was performed to examine Gal-9-induced miRNA expression profiles. We also elucidated if Gal-9 inhibited tumor growth in a murine in vivo model. We found that Gal-9 suppressed the cell proliferation of colon cancer cell lines in vitro and in vivo. Our data further revealed that Gal-9 increased caspase-cleaved keratin 18 levels in Gal-9-treated colon cancer cells. In addition, Gal-9 enhanced the phosphorylation of ALK, DDR1, and EphA10 proteins. Furthermore, the miRNA expression levels, such as miR-1246, miR-15b-5p, and miR-1237, were markedly altered by Gal-9 treatment in vitro and in vivo. In conclusion, Gal-9 suppresses the cell proliferation of human colon cancer by inducing apoptosis, and these findings suggest that Gal-9 can be a potential therapeutic target in the treatment of colon cancer.

Abstract
BACKGROUND Adherence to National Comprehensive Cancer Network guidelines have been adopted as the standard of care for various cancers and have been cited to have survival benefits. Few studies have examined the association of adherent treatment and endometrial cancer survival among various racial/ethnic groups and socioeconomic statuses. METHODS Between January 1, 2006 and December 31, 2015, 83,673 women diagnosed with endometrial carcinomas were identified from the Surveillance, Epidemiology, and End Results database. Descriptive statistics of demographic and clinical characteristics were performed. Cox-proportional hazards models were used to examine the effect on cause-specific survival for adherence to guidelines across racial/ethnic and socioeconomic groups. RESULTS Within our sample, 59.5% were treated according to guidelines. Nonadherence to treatment guidelines was significantly associated with decreased survival compared with adherent care (adjusted hazard ratio [HR], 1.59; 95% CI, 1.52-1.67). Being of Black (adjusted HR, 1.41; 95% CI, 1.32-1.51) or Native Hawaiian/Pacific Islander (adjusted HR, 1.44; 95% CI, 1.19-1.73) race/ethnicity compared with White women was significantly associated with worse survival. Being of Asian race/ethnicity (adjusted HR, 0.86, 95% CI, 0.78-0.94) was significantly associated with improved survival compared with White women. Lower neighborhood socioeconomic status was associated with a negative effect on survival relative to women in the highest socioeconomic status category. CONCLUSIONS Findings from this study suggest treatment adherence is an independent predictor of improved survival; however, improved survival was not observed equally among all racial/ethnic and socioeconomic status groups. LAY SUMMARY The National Comprehensive Cancer Network (NCCN) has developed guidelines for physicians to follow in treating various cancers. Within this study of 83,673 women with endometrial cancer, 59.5% of women were treated according to the NCCN guidelines. The findings suggest following NCCN guidelines for treatment of endometrial cancer improves survival. Black or Native Hawaiian/Pacific Islander race and lower neighborhood socioeconomic status has worse survival rates compared with other groups, indicating the importance of exploring other factors that may shape treatment across racial/ethnic and socioeconomic status groups.

Abstract
OBJECTIVE This study aims to assess age-related treatment patterns and primary reasons for adjusted treatment in patients with colorectal cancer. METHODS Patients with colorectal cancer stage II or III diagnosed between 2015 and 2018 in the Netherlands were eligible for this study. Data were provided by the Netherlands Cancer Registry and included socio-demographics, clinical characteristics, treatment patterns and primary reasons for adjusted treatment. Treatment patterns and reasons for adjusted treatment were analysed according to age groups. RESULTS Of all 29,620 patients, 30% were aged <65 years (n = 8994), 34% between 65 and 75 years (n = 10,173), 27% between 75 and 85 years (n = 8102) and 8% were ≥85 years (n = 2349). Irrespective of cancer location or stage, older patients received less frequently a combination of surgery and (neo)adjuvant therapy compared to younger patients (decreasing from 55% to 1% in colon cancer patients, and from 71% to 23% in rectal cancer patients aged <65 years and ≥85 years respectively). Omission of surgical treatment increased with age in both patients with colon cancer (ranging from 1% in patients aged <65 years to 16% in those ≥85 years) and rectal cancer (ranging from 12% in patients aged <65 years to 56% in those ≥85 years). The most common reasons for adjusted treatment were patient preference (27%) and functional status (20%), both reasons increased with advancing age. CONCLUSIONS Guideline non-adherence increased with advancing age and omission of standard treatment was mainly based on patient preference and functional status. These findings provides insight in the treatment decision-making process in patients with colorectal cancer. Future research is necessary to further assess patient's role in the treatment decision-making process.

Abstract
Patient-specific biomarkers form the foundation of precision medicine strategies. To realize the promise of precision medicine in patients with colorectal cancer (CRC), access to cost-effective, convenient, and safe assays is critical. Improvements in diagnostic technology have enabled ultrasensitive and specific assays to identify cell-free DNA (cfDNA) from a routine blood draw. Clinicians are already employing these minimally invasive assays to identify drivers of therapeutic resistance and measure genomic heterogeneity, particularly when tumor tissue is difficult to access or serial sampling is necessary. As cfDNA diagnostic technology continues to improve, more innovative applications are anticipated. In this review, we focus on four clinical applications for cfDNA analysis in the management of CRC: detecting minimal residual disease, monitoring treatment response in the metastatic setting, identifying drivers of treatment sensitivity and resistance, and guiding therapeutic strategies to overcome resistance.

Abstract
BACKGROUND Non-Hispanic black (NHB) adults with cancer may have longer time-to-treatment than non-Hispanic whites (NHW) in the United States. Unequal access to medical care may partially account for this racial disparity. This study aimed to investigate whether there were racial differences in time-to-treatment and in treatment delays for patients diagnosed with colon cancer in the equal-access Military Health System (MHS). METHODS Patients age 18-79 years diagnosed with colon adenocarcinoma between January 1, 1998, and December 31, 2014, were identified in the Department of Defense Central Cancer Registry and the MHS Data Repository-linked databases. Median time-to-treatment (surgery and chemotherapy) and 95% confidence intervals were compared between NHBs and NHWs in multivariable quantile regression models. Odds ratios and 95% confidence intervals of receiving delayed treatment defined by guidelines for NHBs relative to NHWs were estimated using multivariable logistic regression. RESULTS Patients (n = 3067) had a mean age at diagnosis of 58.4 (12.2) years and the racial distribution was 76.7% NHW and 23.3% NHB. Median adjusted time-to-treatment was similar for NHB compared to NHW patients. The likelihood of receiving delayed treatment was similar between NHB and NHW patients. CONCLUSIONS In the MHS, there was no evidence of treatment delays for NHBs compared to NHWs, suggesting the role of equal access to medical care and insurance coverage in reducing racial disparities in colon cancer treatment.

Abstract
Background: We examined paradoxical and barrio advantaging effects on cancer care among socioeconomically vulnerable Hispanic people in California. Methods: We secondarily analyzed a colon cancer cohort of 3,877 non-Hispanic white (NHW) and 735 Hispanic people treated between 1995 and 2005. A third of the cohort was selected from high poverty neighborhoods. Hispanic enclaves and Mexican American (MA) barrios were neighborhoods where 40% or more of the residents were Hispanic or MA. Key analyses were restricted to high poverty neighborhoods. Results: Hispanic people were more likely to receive chemotherapy (RR=1.18), especially men in Hispanic enclaves (RR=1.33) who were also advantaged on survival (RR=1.20). A survival advantage was also suggested among MA men who resided in barrios (RR=1.80). Conclusions: The findings were supportive of Hispanic paradox and MA barrio advantage theories. They further suggested that such advantages are greater for men, perhaps due to their greater spousal and extended familial support.

Abstract
In this study, we collected genes related to energy metabolism, used gene expression data from public databases to classify molecular subtypes of colon cancer (COAD) based on the genes related to energy metabolism, and further evaluated the relationships between the molecular subtypes and prognosis and clinical characteristics. Differential expression analysis of the molecular subtypes yielded 1948 differentially expressed genes (DEGs), whose functions were closely related to the occurrence and development of cancer. Based on the DEGs, we constructed a 4-gene prognostic risk model and identified the high expression of FOXD4, ENPEP, HOXC6, and ALOX15B as a risk factor associated with a high risk of developing COAD. The 4-gene signature has strong robustness and a stable predictive performance in datasets from different platforms not only in patients with early COAD but also in all patients with colon cancer. The enriched pathways of the 4-gene signature in the high- and low-risk groups obtained by GSEA were significantly related to the occurrence and development of colon cancer. Moreover, the results of qPCR, immunohistochemistry staining and Western blot assay revealed that FOXD4, ENPEP, HOXC6, and ALOX15B are over expressed in CRC tissues and cells. These results suggesting that the signature could potentially be used as a prognostic marker for clinical diagnosis.

Abstract
Colon cancer is the third leading cause of cancer-related death in African Americans. Although the rates of colon screenings have risen, African Americans remain to be underscreened, and are more likely to present with advanced lesions. This population has a higher prevalence of inflammatory comorbidities, and their effects on screenings have not been fully explored. Along with higher rates of comorbidities, the Southeastern United States is one region for the highest rates of colorectal cancer. The purpose of this study was to determine whether people with comorbidities were more likely to have a screening colonoscopy. Convenience sampling was used to procure 408 patients. The median age was 55 years, and the majority were females (52.2%), who were obese (29.2%), and nonsmokers (52.2%). The most common comorbidity was hypertension (70.3%), followed by osteoarthritis (39%), and diabetes (25.5%). There is a well-documented trend between certain inflammatory comorbidities and higher death rates in patients with colorectal cancer. Clarifying the relationship between comorbidities and cancer starts with screening as many patients as possible. Therefore, interventions that support increasing the number of colorectal cancer screenings are imperative in order to improve morbidity and mortality in this despaired population.

Abstract
Importance Patients with head and neck squamous cell cancer (HNSCC) are often uninsured or underinsured at the time of their diagnosis. This access to care has been shown to influence treatment decisions and survival outcomes. Objective To examine the association of the Patient Protection and Affordable Care Act (ACA) health care legislation with rates of insurance coverage and access to care among patients with HNSCC. Design, Setting, and Participants Prospectively gathered data from the Surveillance, Epidemiology, and End Results (SEER) database were used to examine rates of insurance coverage and access to care among 89 038 patients with newly diagnosed HNSCC from January 2007 to December 2014. Rates of insurance were compared between states that elected to expand Medicaid coverage in 2014 and states that opted out of the expansion. Statistical analysis was performed from January 1, 2007, to December 31, 2014. Main Outcomes and Measures Rates of insurance coverage and disease-specific and overall survival. Results Among 89 038 patients newly diagnosed with HNSCC (29 384 women and 59 654 men; mean [SD] age, 59.8 [7.6] years), there was an increase after implementation of the ACA in the percentage of patients enrolled in Medicaid (16.2% after vs 14.8% before; difference, 1.4%; 95% CI, 1.1%-1.7%) and private insurance (80.7% after vs 78.9% before; difference, 1.8%; 95% CI, 1.2%-2.4%). In addition, there was a large decrease in the rate of uninsured patients after implementation of the ACA (3.0% after vs 6.2% before; difference, 3.2%; 95% CI, 2.9%-3.5%). This decrease in the rate of uninsured patients and the associated increases in Medicaid and private insurance coverage were only different in the states that adopted the Medicaid expansion in 2014. No survival data are available after implementation of the ACA, but prior to that point, from 2007 to 2013, uninsured patients had reduced 5-year overall survival (48.5% vs 62.5%; difference, 14.0%; 95% CI, 12.8%-15.2%) and 5-year disease-specific survival compared with insured patients (56.6% vs 72.2%; difference, 15.6%; 95% CI, 14.0%-17.2%). Conclusions and Relevance Access to health care for patients with HNSCC was improved after implementation of the ACA, with an increase in rates of both Medicaid and private insurance and a 2-fold decrease in the rate of uninsured patients. These outcomes were demonstrated only in states that adopted the Medicaid expansion in 2014. Uninsured patients had poorer survival outcomes.

Abstract
Background Chemotherapy induced diarrhea (CID) is a common side effect in patients receiving chemotherapy for cancer. The aim of our study was to explore the association between gut microorganisms and CID from the CapeOX regimen in resected stage III colorectal cancer (CRC) patients. Results After screening and identification, 17 stool samples were collected from resected stage III CRC patients undergoing the CapeOX regimen. Bacterial 16S ribosomal RNA genes was sequenced, and a bioinformatics analysis was executed to screen for the distinctive gut microbiome and the functional metabolism associated with CID due to the CapeOX regimen. The gut microbial community richness and community diversity were lower in CID (p < 0.05 vs control group). Klebsiella pneumoniae was the most predominant species (31.22%) among the gut microbiome in CRC patients with CID. There were 75 microorganisms with statistically significant differences at the species level between the CRC patients with and without CID (LDA, linear discriminant analysis score > 2), and there were 23 pathways that the differential microorganisms might be involved in. Conclusions The gut microbial community structure and diversity have changed in CRC patients with CID. It may provide novel insights into the prevention and treatment of CID.

Abstract
PURPOSE To assess and explain variation in quality of care in breast cancer patients and estimate its impact on disease outcome. METHODS The Slovenian National Cancer Registry database and clinical records of 1053 women with unilateral primarily non-metastatic invasive breast cancer diagnosed in 2013 were reviewed in this retrospective analysis. Quality care was defined as care fully compliant with quality indicators (QI) defined by European Society of Breast Cancer Specialists (EUSOMA). Multivariate logistic regression was used to determine the predictors of receiving quality care. Differences in overall survival (OS) and event-free survival (EFS, relapse, or progression of disease or death considered an event) based on adherence to QI were analyzed using Kaplan-Meier method and Cox models. RESULTS Younger age, no comorbidities, and HER2-negative tumor were associated with increased odds ratios for receiving quality care, whereas tumor stage and type of hospital had no significant association. Median follow-up was 54.5 months. Not receiving quality care resulted in an increased risk of dying [hazard ratio (HR) 1.68; 95% confidence interval (CI) 1.06-2.66; p = 0.026]. Difference in EFS between two groups was significant after adjusting for case mix and type of hospital (HR 1.80; 95% CI 1.29-2.52; p = 0.001) but disappeared when type of treatment was added into the model (HR 1.30; 95% CI 0.89-1.90; p = 0.178). CONCLUSION Observed comorbidity and age bias in delivering quality breast cancer care could be medically justifiable, whereas observed deviations dependent on HER2 status are puzzling. Complete adherence of treatment to quality indicators resulted in better OS.

Abstract
PURPOSE The number of octogenarians with rectal adenocarcinoma is growing. Current guidelines seem difficult to apply on octogenarians which may result in non-adherence. The aim of this retrospective cohort study is to give insight in occurrence of treatment-related complications, hospitalisations and survival among octogenarians treated according to guidelines versus octogenarians treated otherwise. METHODS 108 octogenarians with rectal adenocarcinoma were identified by screening of medical records. 22 patients were excluded for treatment process analysis because of stage IV disease or unknown stage. Baseline characteristics, diagnostic process, received treatment, motivation for deviation from guidelines, complications, hospitalisations and date of death were documented. Patients were divided in two groups depending on adherence to treatment guidelines. Differences in baseline characteristics, treatment-related complications and survival between both groups were evaluated. RESULTS Diagnosis and treatment according to guidelines occurred in 95 and 54% of the patients, respectively. When documented, patient's preference and comorbidities were major reasons to deviate from guidelines. 66% of patients who were treated according to guidelines experienced complications versus 34% of those treated otherwise (p = 0.02). After adjustment for differences in age and polypharmacy, this association was not significant. Patients treated according to the guideline had better survival 18 months after diagnosis (80 versus 56%, p = 0.02). CONCLUSIONS Treating octogenarians with rectal cancer according to guidelines seem to lead to better overall survival, but may lead to a high risk of complications. This may jeopardise quality of life. More and prospective studies in octogenarians with rectal cancer are needed to customize guidelines for these patients.

Abstract
INTRODUCTION Although the colorectal cancer (CRC) mortality rate has significantly improved over the past several decades, many patients will have a recurrence following curative treatment. Despite this high risk of recurrence, adherence to CRC surveillance testing guidelines is poor which increases cancer-related morbidity and potentially, mortality. Several randomised controlled trials (RCTs) with varying surveillance strategies have yielded conflicting evidence regarding the survival benefit associated with surveillance testing. However, due to differences in study protocols and limitations of sample size and length of follow-up, the RCT may not be the best study design to evaluate this relationship. An observational comparative effectiveness research study can overcome the sample size/follow-up limitations of RCT designs while assessing real-world variability in receipt of surveillance testing to provide much needed evidence on this important clinical issue. The gap in knowledge that this study will address concerns whether adherence to National Comprehensive Cancer Network CRC surveillance guidelines improves survival. METHODS AND ANALYSIS Patients with colon and rectal cancer aged 66-84 years, who have been diagnosed between 2002 and 2008 and have been included in the Surveillance, Epidemiology, and End Results-Medicare database, are eligible for this retrospective cohort study. To minimise bias, patients had to survive at least 12 months following the completion of treatment. Adherence to surveillance testing up to 5 years post-treatment will be assessed in each year of follow-up and overall. Binomial regression will be used to assess the association between patients' characteristics and adherence. Survival analysis will be conducted to assess the association between adherence and 5-year survival. ETHICS AND DISSEMINATION This study was approved by the National Cancer Institute and the Institutional Review Board of the University of Central Florida. The results of this study will be disseminated by publishing in the peer-reviewed scientific literature, presentation at national/international scientific conferences and posting through social media.

Abstract
BACKGROUND & AIMS Recommendations for surveillance after curative surgery for colorectal cancer (CRC) include a 1-year post-resection abdominal-pelvic computed tomography (CT) scan and optical colonoscopy (OC). CT colonography (CTC), when used in CRC screening, effectively identifies colorectal polyps ≥10 mm and cancers. We performed a prospective study to determine whether CTC, concurrent with CT, could substitute for OC in CRC surveillance. METHODS Our study enrolled 231 patients with resected stage 0-III CRC, identified at 5 tertiary care academic centers. Approximately 1 year after surgery, participants underwent outpatient CTC plus CT, followed by same-day OC. CTC results were revealed after endoscopic visualization of sequential colonic segments, which were re-examined for discordant findings. The primary outcome was performance of CTC in the detection of colorectal adenomas and cancers using endoscopy as the reference standard. RESULTS Of the 231 participants, 116 (50.2%) had polyps of any size or histology identified by OC, and 15.6% had conventional adenomas and/or serrated polyps ≥6 mm. No intra-luminal cancers were detected. CTC detected patients with polyps of ≥6 mm with 44.0% sensitivity (95% CI, 30.2-57.8) and 93.4% specificity (95% CI, 89.7-97.0). CTC detected polyps ≥10 mm with 76.9% sensitivity (95% CI, 54.0-99.8) and 89.0% specificity (95% CI, 84.8-93.1). Similar values were found when only adenomatous polyps were considered. The negative predictive value of CTC for adenomas ≥6 mm was 90.7% (95% CI, 86.7-94.5) and for adenomas ≥10 mm the negative predictive value was 98.6% (95% CI, 97.0-100). CONCLUSIONS In a CRC surveillance population 1 year following resection, CTC was inferior to OC for detecting patients with polyps ≥6 mm. Clinical Trials.gov Registration Number: NCT02143115.

Abstract
The literature describing the effectiveness of multidisciplinary team (MDT) for the care of colorectal cancer remains unclear. We investigated the effects of MDT care on the quality of colorectal cancer treatment, and the emergency department visit number was used as an indicator. In total, 45,418 patients newly diagnosed with colorectal cancer from the Taiwan National Health Insurance Research Database (2005-2009) were included. Propensity score matching with a ratio of 1:3 was adopted to reduce differences in characteristics between MDT care participants and non-MDT care participants. After matching, 3039 participation MDT care groups and 9117 nonparticipation groups were included and analyzed with χ and t tests, determine the distribution was similar. Without the control of variables, the percentage difference between participation and nonparticipation MDT care groups in utilization of emergency care was 0.03% (P > .05). The logistic regression model involving controlled variables demonstrated that odds ratio (OR) by probability of emergency care used for participation MDT care groups within a year of cancer diagnosis was less than that for nonparticipation (OR = 0.87, 95% confidence interval: 0.78-0.96). Large amount data were used and confirmed significant benefits of MDT in colorectal cancer care.

Abstract
BACKGROUND Fostering surgeon engagement in community outreach was recently identified as a major priority toward reducing health care disparities in surgery. We aimed to increase surgeon engagement in the local community, understand prevalent beliefs, and identify educational opportunities in the local community regarding cancer screening and treatment using community outreach. MATERIALS AND METHODS In collaboration with the university's cancer center, the medical student surgical interest group, surgical faculty, and residents developed a community outreach program. The program consisted of networking time, a formal presentation, panel discussion, and question and answer time. A survey was distributed to all participants before the educational session, and a program assessment was distributed at the program's conclusion. RESULTS A total of 256 community members and 22 surgical volunteers attended at least one of the two events. Attendees were insured (175; 92.7%), female (151; 80%), and African-American (176; 93.1%), with a mean age of 61 y (standard deviation 14.0). About 56 participants (29.6%) were unwilling to undergo screening colonoscopy. Forty-eight respondents (25.4%) endorsed mistrust in doctors and 25% believed surgery causes cancer to spread; a significantly higher proportion of them aged <60 y old. About 113 (59.8%) and 87 (46.1%) misunderstood the definitions of malignant and metastatic, respectively. Males were more unsure than females (61% versus 55%, P = 0.5 and 70% versus 55%; P = 0.01). CONCLUSIONS Risk perceptions related to fatalism, mistrust, or lack of knowledge were prevalent. The ability of surgeons to reach at-risk populations in the prehospital setting is an important opportunity waiting to be capitalized upon.

Abstract
The aim of the study is to determine the influence of area-level socio-economic status and healthcare access in addition to tumor hormone-receptor subtype on individual breast cancer stage, treatment, and mortality among Non-Hispanic (NH)-Black, NH-White, and Hispanic US adults. Analysis was based on 456,217 breast cancer patients in the SEER database from 2000 to 2010. Multilevel and multivariable-adjusted logistic and Cox proportional hazards regression analysis was conducted to account for clustering by SEER registry of diagnosis. NH-Black women had greater area-level access to healthcare resources compared with women of other races. For instance, the average numbers of oncology hospitals per million population in counties with NH-Black, NH-White, and Hispanic women were 8.1, 7.7, and 5.0 respectively; average numbers of medical doctors per million in counties with NH-Black, NH-White, and Hispanic women were 100.7, 854.0, and 866.3 respectively; and average number of Ob/Gyn in counties with NH-Black, NH-White, and Hispanic women was 155.6, 127.4, and 127.3, respectively (all p values <0.001). Regardless, NH-Black women (HR 1.39, 95 % CI 1.36-1.43) and Hispanic women (HR 1.05, 95 % CI 1.03-1.08) had significantly higher breast cancer mortality compared with NH-White women even after adjusting for hormone-receptor subtype, area-level socio-economic status, and area-level healthcare access. In addition, lower county-level socio-economic status and healthcare access measures were significantly and independently associated with stage at presentation, surgery, and radiation treatment as well as mortality after adjusting for age, race/ethnicity, and HR subtype. Although breast cancer HR subtype is a strong, important, and consistent predictor of breast cancer outcomes, we still observed significant and independent influences of area-level SES and HCA on breast cancer outcomes that deserve further study and may be critical to eliminating breast cancer outcome disparities.

Abstract
BACKGROUND Our research group advanced a health insurance theory to explain Canada's cancer care advantages over America. The late Barbara Starfield theorized that Canada's greater primary care-orientation also plays a critically protective role. We tested the resultant Starfield-Gorey theory by examining the effects of poverty, health insurance and physician supplies, primary care and specialists, on colon cancer care in Ontario and California. METHODS We analyzed registry data for people with non-metastasized colon cancer from Ontario (n = 2,060) and California (n = 4,574) diagnosed between 1996 and 2000 and followed to 2010. We obtained census tract-based socioeconomic data from population censuses and data on county-level physician supplies from national repositories: primary care physicians, gastroenterologists and other specialists. High poverty neighborhoods were oversampled and the criterion was 10 year survival. Hypotheses were explored with standardized rate ratios (RR) and tested with logistic regression models. RESULTS Significant inverse associations of poverty (RR = 0.79) and inadequate health insurance (RR = 0.80) with survival were observed in the California, while they were non-significant or non-existent in Ontario. The direct associations of primary care physician (RRs of 1.32 versus 1.11) and gastroenterologist (RRs of 1.56 versus 1.15) supplies with survival were both stronger in Ontario than California. The supply of primary care physicians took precedence. Probably mediated through the initial course of treatment, it largely explained the Canadian advantage. CONCLUSIONS Poverty and health insurance were more predictive in the USA, community physician supplies more so in Canada. Canada's primary care protections were greatest among the most socioeconomically vulnerable. The protective effects of Canadian health care prior to enactment of the Affordable Care Act (ACA) clearly suggested the following. Notwithstanding the importance of insuring all, strengthening America's system of primary care will probably be the best way to ensure that the ACA's full benefits are realized. Finally, Canada's strong primary care system ought to be maintained.
