[PMID: 38756642 PMCID: PMC11094497 DOI: 10.21037/jgo-24-168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Accepted: 04/18/2024] [Indexed: 05/18/2024] Open
Abstract
Background Early gastric cancer (EGC) is defined as cancer cells confined to the mucosal or submucosal layer, irrespective of size or presence of lymph node metastasis. The recent EGC endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) guidelines (2021 Japan Gastroenterological Endoscopy Society (JGES) guidelines, 2nd edition) revised the concept from "endoscopic curative/non-curative resection" (NCR) to "endoscopic curability (eCura)". Under this, eCuraA and eCuraB signify curative resections (CRs), while eCuraC (including eCuraC-1 and eCura-C2) indicate NCRs. This study retrospectively analyzes clinical and pathological data from EGC patients who underwent endoscopic resection, assessing the long-term clinical outcomes in a substantial cohort after undergoing NCR. Methods We retrospectively analyzed clinical and pathological data from 443 EGC patients, encompassing 478 lesions, who received endoscopic treatment. The long-term clinical outcomes of patients who underwent NCR were statistically evaluated. Characteristics of the NCR group were compared with those of the surgical group, employing single- and multi-factor logistic regression analyses to identify risk factors that necessitate further surgical intervention. Prognostically, the Kaplan-Meier method and Log-Rank test determined the impact of risk factors on recurrence-free survival post-surgery in NCR patients. Differences were assessed using a method incorporating statistically significant differences in the multi-factor Cox regression analysis, evaluating the hazard ratio (HR) for disease recurrence following NCR. Results In this study, 443 EGC cases were pathologically diagnosed, comprising a total of 478 lesions. Of these, 127 cases underwent non-curative endoscopic resection, resulting in a NCR rate of 24.4%. Long-term follow-up was achieved for 117 (92.12%) patients. The metastasis/recurrence rate at 6 months stood at 23.1%. Multivariate Cox regression analysis identified lesion size ≥2.0 and <3 cm [P=0.02, HR =0.12, 95% confidence interval (CI): 0.02-0.67], presence of ulceration (P=0.03, HR =5.48, 95% CI: 1.23-24.33), lymphatic invasion (P=0.05, HR =17.51, 95% CI: 1.07-286.23), positive vertical margins (P=0.09, HR =3.77, 95% CI: 0.81-17.53), and flat macroscopic morphology (P=0.048, HR =4.8, 95% CI: 1.01-22.73) as independent risk factors for recurrence-free survival post non-curative endoscopic resection in EGC patients. Conclusions The recurrence/metastasis rate in patients who underwent NCR is notably higher compared to the control group. Significant prognostic risk factors include tumor size ≥2.0 and <3 cm, positive vertical margins, lymphatic invasion, and flat type (one of pathological gross classification). Patients in the eCuraC-2 category of NCR should consider further surgical intervention. The necessity for additional surgical intervention in these patients warrants further investigation.

Sun M, Zhao B, Chen T, Yao L, Li X, Hu S, Chen C, Gao X, Tang C. Novel molecular typing reveals the risk of recurrence in patients with early-stage papillary thyroid cancer. Thyroid Res 2024; 17:7. [PMID: 38556856 PMCID: PMC10983671 DOI: 10.1186/s13044-024-00193-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Accepted: 02/06/2024] [Indexed: 04/02/2024] Open
Abstract
BACKGROUND Papillary thyroid cancer (PTC) is an indolent disease with a favorable prognosis but characterized by a high recurrence rate. We aimed to improve precise stratification of recurrence risk in PTC patients with early stage using multi-gene signatures. PATIENTS AND METHODS The present study was performed using data from The Cancer Genome Atlas (TCGA) and multi-center datasets. Unsupervised consensus clustering was used to obtain the optimal molecular subtypes and least absolute shrinkage and selection operator (LASSO) analysis was performed to identify potential genes for the construction of recurrence signature. Kaplan-Meier survival analysis and the log-rank test was used to detect survival differences. Harrells concordance index (C-index) was used to assess the performance of the DNA damage repair (DDR) recurrence signature. RESULTS Through screening 8 candidate gene sets, the entire cohort was successfully stratified into two recurrence-related molecular subtypes based on DDR genes: DDR-high subtype and DDR-low subtype. The recurrence rate of DDR-high subtype was significantly lower than DDR-low subtype [HR = 0.288 (95%CI, 0.084-0.986), P = 0.047]. Further, a two-gene DDR recurrence signature was constructed, including PER1 and EME2. The high-risk group showed a significantly worse recurrence-free survival (RFS) than the low-risk group [HR = 10.647 (95%CI, 1.363-83.197), P = 0.024]. The multi-center data demonstrated that proportion of patients with low expression of PER1 and EME2 was higher in the recurrence group than those in the non-recurrence group. CONCLUSIONS These findings could help accurately and reliably identify PTC patients with high risk of recurrence so that they could receive more radical and aggressive treatment strategies and more rigorous surveillance practices.

Real-world treatment patterns and clinical outcomes in patients with stage III NSCLC in Korea: The KINDLE study. Cancer Med 2024; 13:e7174. [PMID: 38622869 PMCID: PMC11019151 DOI: 10.1002/cam4.7174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 01/31/2024] [Accepted: 03/27/2024] [Indexed: 04/17/2024] Open
Abstract
OBJECTIVE KINDLE-Korea is part of a real-world KINDLE study that aimed to characterize the treatment patterns and clinical outcomes of patients with stage III non-small cell lung cancer (NSCLC). MATERIALS AND METHODS The KINDLE was an international real-world study that explores patient and disease characteristics, treatment patterns, and survival outcomes. The KINDLE-Korea included stage III NSCLC patients diagnosed between January 2013 and December 2017. RESULTS A total of 461 patients were enrolled. The median age was 66 years (range: 24-87). Most patients were men (75.7%) with a history of smoking (74.0%), stage IIIA NSCLC (69.2%), and unresectable disease (52.9%). A total of 24.3% had activating EGFR mutation and 62.2% were positive for PDL1 expression. Broadly categorized, 44.6% of the patients received chemoradiation (CRT)-based therapy, 35.1% underwent surgery, and 20.3% received palliative therapies as initial treatment. The most commonly adopted approaches for patients with stage IIIA and IIIB disease were surgery and CRT, respectively. The median PFS was 15.2 months and OS was 66.7 months. Age >65 years, adenocarcinoma histology, and surgery as the initial treatment were significantly associated with longer OS. CONCLUSION This study revealed the heterogeneity of treatment patterns and survival outcomes in patients with stage III NSCLC before durvalumab consolidation came into clinical practice. There is an unmet need for patients who are not eligible for surgery as an initial therapy. Novel therapeutic approaches are highly warranted to improve clinical outcomes.

Abstract
BACKGROUND Gastric cancer (GC) is one of the most common malignant tumors, and its long-term overall survival (OS) still needs to be improved. This study aimed to elucidate the relationship between serum ferritin (SF) and sarcopenia and its ability to predict long-term OS for GC patients. METHODS Clinicopathological data from GC patients who underwent radical gastrectomy were reviewed and received 3 years of follow-up after surgery. The correlation between SF and sarcopenia was determined by Spearman analysis. Factors used to establish a nomogram to predict the 3-year OS for GC were identified by multivariate Cox hazard analysis. RESULTS We retrospectively identified 372 GC patients after surgery and randomly divided (3:1) into a training cohort and a validation cohort. The correlation coefficient between SF and sarcopenia was 0.323. GC patients with SF < 151.5 μg/L had a significantly longer 3-year OS. The variables of the nomogram include SF, sarcopenia, TNM stage system, and neoadjuvant chemotherapy. In the training cohort and validation cohort, the area under the time-dependent ROC curve was 0.81 and 0.791, respectively. The calibration curve and decision curve in different cohorts have good consistency. 3-year OS was significantly different among the three groups (log-rank P < 0.001) divided by calculating the nomogram score. CONCLUSION SF was positively correlated with sarcopenia, and the nomogram was a practical tool for predicting 3-year OS after radical gastrectomy, furthermore could be used to stratify the risk of 3-year OS in patients with GC.

Abstract
PURPOSE Overall, thyroid cancer is the most common endocrine malignancy. This cancer is fifth most common cancer among adult women and the second most common cancer in women over 50 years old and it occurs in women 3 times more than men. The present systematic review and meta-analysis were designed with the aim of determining the 5-year survival rate of thyroid cancer in Asian countries in 2022. METHODS The current study is a systematic review and meta-analysis of thyroid cancer survival rates in Asian countries. Researchers in the study searched for articles published in six international databases: PubMed/Medline, EMBASE, Scopus, Google Scholar, ISI (Web of Knowledge), and ProQuest until July 03, 2022. A checklist (The Newcastle-Ottawa Quality Assessment Form) has been prepared in previous studies to evaluate the quality of articles. RESULTS In general, 38 articles were entered for the meta-analysis. The 5-year survival rate was 95.3%, with a 95% confidence interval of 93.5% to 96.6%. The year of study is a cause of variability in results of 5-year (Reg Coef = 0.145, P < 0.001). According to the results, an increased survival rate across the study period was observed. Human Development Index was a cause of variability in results of 5-year survival rates (Reg Coef = 12.420, P < 0.001). The results of Table 2 showed that women have 4% more 5-year survival rate than men (Hazard ratio: 1.05 CI: 95% 1.04-1.06)). CONCLUSION In general, the 5-year survival of thyroid cancer in Asian countries was higher than in European countries, but it is at a lower level than in the United States.

Tumour area infiltration and cell count in endoscopic biopsies of therapy-naive upper GI tract carcinomas by QuPath analysis: implications for predictive biomarker testing. Sci Rep 2023; 13:17580. [PMID: 37845307 PMCID: PMC10579338 DOI: 10.1038/s41598-023-43903-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Accepted: 09/29/2023] [Indexed: 10/18/2023] Open
Abstract
Guidelines regulate how many (tumour-bearing) tissue particles should be sampled during gastric cancer biopsy to obtain representative results in predictive biomarker testing. Little is known about how well these guidelines are applied, how the number of tissue particles correlates with the actual tumour-infiltrated area and how many absolute tumour cells are captured. The study included endoscopic biopsies of untreated carcinomas of the upper gastrointestinal (GI)-tract during the 2016-2020 review period. Archival (H&E)-stained histological sections were digitised and the tumour areas were manually annotated. The tumour-bearing tissue area and absolute carcinoma cell count per case were determined by image analysis and compared with a reference primary surgical specimen. Biopsies from 253 patients were analysed. The following mean values were determined: (a) tumour tissue particle number: 6.5 (range: 1-25, standard deviation (SD) = 3.33), (b) number of tumour-bearing tissue particles: 4.7 (range: 1-20, SD = 2.80), (c) tumour-infiltrated area: 7.5 mm2 (range: 0.18-59.46 mm2, SD = 6.67 mm2), (d) absolute tumour cell count: 13,492 (range: 193-92,834, SD = 14,185) and (e) tumour cell count in a primary surgical specimen (tumour size: 6.7 cm): 105,200,176. The guideline-recommended tissue particle count of 10 was not achieved in 208 patients (82.2%) and the required tumour-bearing tissue particle count of 5 was not achieved in 133 patients (52.6%). Tissue particle count, tumour-infiltrated area and tumour cell count were only weakly correlated. Most cases featured an infiltrated area ≥ 4.5 mm2 (156, 61.7%). Cases with more tissue particles showed only a moderate increase in infiltrated area and tumour cells compared to cases with fewer particles. Biopsies are often used to determine predictive biomarkers, particularly Her2/neu and PD-L1. Diagnostic standards to ensure representative material have been suggested in guidelines to reduce false-negative predictions. However, the real-world practice seems to substantially deviate from recommended standards. To the best of our knowledge, this is the first systematic study describing the relationships between endoscopic tissue fragment number, actual infiltrated tumour area and carcinoma cell number. The data question the tissue particle number as a quality assessment parameter. We advocate histopathological reports indicating on which basis statements on therapy-relevant biomarkers were made. Digital pathology has the potential to objectively quantify the tissue for documentation, quality assessment and future clinical studies.

Abstract
Background/Aims The incidence and prognosis of gastric cancer (GC) shows sex difference. This study aimed to evaluate the effect of body mass index (BMI) on GC survival depending on sex. Methods The sex, age, location, histology, TNM stages, BMI, and survival were analyzed in GC patients from May 2003 to February 2020 at the Seoul National University Bundang Hospital. Results Among 14,688 patients, there were twice as many males (66.6%) as females (33.4%). However, under age 40 years, females (8.6%) were more prevalent than males (3.1%). Cardia GC in males showed a U-shaped distribution for underweight (9.6%), normal (6.4%), overweight (6.1%), obesity (5.6%), and severe obesity (9.3%) but not in females (p=0.003). Females showed decreased proportion of diffuse-type GC regarding BMI (underweight [59.9%], normal [56.8%], overweight [49.5%], obesity [44.8%], and severe obesity [41.7%]), but males did not (p<0.001). Both sexes had the worst prognosis in the underweight group (p<0.001), and the higher BMI, the better prognosis in males, but not females. Sex differences in prognosis according to BMI tended to be more prominent in males than in females in subgroup analysis of TNM stages I, II, and III and the operative treatment group. Conclusions GC-specific survival was affected by BMI in a sex-dependent manner. These differences may be related to genetic, and environmental, hormonal factors; body composition; and muscle mass (Trial registration number: NCT04973631).

Abstract
OBJECTIVE To describe the incidence and survival outcomes of uterine cervical cancer during 1999-2018. METHODS Patients who were diagnosed with cervical cancer during 1999-2018 were identified in the Korea Central Cancer Registry. Age-standardized incidence rates (ASRs) and annual percent changes (APCs) were calculated. Survival rates by histology, year of diagnosis (1999-2008 vs. 2009-2018), stage, and age at diagnosis were analyzed. RESULTS The absolute incidence of cervical cancer decreased over 20 years from 4,488 in 1999 to 3,500 in 2018, with an APC of -3.42% (p<0.0001). While ASR of squamous cell carcinoma (SCCA) more than halved from 13.27 per 100,000 in 1999 to 6.16 in 2018 (APC, -4.04%), adenocarcinoma continued to rise (ASR, 1.30 per 100,000 to 1.92; APC, 1.52%; p<0.0001). Patients with adenocarcinoma were younger than those with SCCA (mean, 49.9±12.7 vs. 52.9 ±14.6 years; p<0.0001). Five-year survival rate of cervical cancer patients overall was 78.0%. Adenocarcinoma had poorer survival than SCCA (5-year survival rate, 76.8% vs. 79.8%; p<0.0001). There was no survival difference between patients who were diagnosed between 1999-2008 and 2009-2018. Earlier-stage disease had better survival (5-year survival rate for localized, regional, and distant disease, 90.0% vs. 69.9% vs. 26.5%; p<0.0001). Younger patients aged <50 years had better survival than those aged ≥50 years (87.1% vs. 69.8%; p<0.0001). CONCLUSION The incidence of SCCA of the uterine cervix declined while adenocarcinoma continued to increase slowly but significantly from 1999 to 2018 in Korea. Adenocarcinoma was diagnosed at a younger age, but had poorer survival outcome than SCCA.

[PMID: 35832556 PMCID: PMC9271972 DOI: 10.3389/fonc.2022.862173] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Accepted: 04/25/2022] [Indexed: 11/13/2022] Open
Abstract
BackgroundThe burden of care continues to rise considerably worldwide and the challenge of diversity in cancer research has become important. We aimed to examine trends of cancer care utilization and anti-cancer medication among patients with six solid cancers (gastric, colorectal, liver, lung, breast, and prostate cancer) in South Korea.MethodsThis study analyzed patients diagnosed with six types of solid cancer from 2007 to 2019 using data from the National Health Insurance claims database. We analyzed the total number of cancer cases, each patient’s length of stay (LOS) in a hospital, the number of outpatient physician visits, total medical care costs, total out-of-pocket (OOP) costs, and expenditures on anti-cancer drugs.ResultsUtilization of healthcare services and spending on cancer care including anti-cancer drugs both increased in the 13-year study period. The average LOS was the highest for colorectal cancer patients at 43.5 days, and breast cancer patients had the highest average number of physician visits at 11.8. Breast cancer patients had the highest total medical costs (USD 923 million), anti-cancer drug spending (USD 156 million), and the largest increase (5 times) over the 13-year period. The anti-cancer drugs with the largest market shares were ramucirumab for gastric cancer; oxaliplatin for colorectal cancer; sorafenib for liver cancer; pembrolizumab, nivolumab, for lung cancer; trastuzumab for breast cancer; and bicalutamide for prostate cancer.ConclusionThis study was a large-scale analysis from a nationally representative database of the total population. The study also shows the pattern of cancer care in an Asian country and can provide implications for future cancer research.

Abstract
Background: The thyroid nodules incidence has risen worldwide. Although factors such as increasing the use of imaging techniques and more rapid detection of small thyroid nodules have been implicated in the recent rise in thyroid cancer incidence, some environmental parameters such as infectious agents may be involved. Helicobacter pylori infection is an environmental risk factor, which may mimic the antigenic properties of membranes of thyrocytes. Objectives: This study aimed at evaluating the association of H. pylori infection with benign and malignant thyroid nodules in comparison with the control group. Methods: Patients with benign thyroid nodules, papillary thyroid cancer (PTC), and euthyroid healthy controls without thyroid nodules that had just been diagnosed were included in the study. All participants underwent clinical examination. Various biochemical parameters such as serum H. pylori Ab (IgG) and thyroid function tests were measured. Comparisons were made between groups. Results: Finally, 370 patients with benign thyroid nodules, 364 patients with PTC, and 360 healthy subjects without nodules participated as a control group. In the patients with PTC, the prevalence of H. pylori infection was 89.6%, while in the group of patients with benign thyroid nodules and the control group was 81.1% and 75%, respectively (P < 0.001). Helicobacter pylori antibody (Ab) titer was not significantly associated with any of the anthropometric and biochemical variables. Conclusions: Helicobacter pylori infection was significantly higher in patients with benign thyroid nodules and PTC than in the control group. Also, the rate of infection was significantly higher in the malignant nodule group than in the benign thyroid nodules group.

Abstract
Aims The incidence and mortality of hepatocellular carcinoma (HCC) have decreased over time in South Korea, where hepatitis B virus (HBV) in endemic. This study investigated the changes in the characteristics and clinical outcomes of HCC patients in Korea. Methods Patients initially diagnosed with HCC and treated at the National Cancer Center, Korea between 2000 and 2015 (n = 4,291) were followed up until February 2017. Differences in patient characteristics and outcomes were compared between chronological cohorts: cohort A (2000–2004, n = 1,157) vs. B (2005–2009, n = 1,678) vs. C (2010–2015, n = 1,456). Results The median age of the patient cohort was 57 years (range, 13–98 years), and male predominance was noted (81.6%). HBV infection was the most common etiology (74.8%). The proportion of patients diagnosed with good liver function and small tumors (<2 cm) increased significantly over time: 74.6%, 79.9%, and 87.4% for Child–Pugh class A (p<0.001) and 8.0%, 8.5%, and 12.0% for modified UICC stage I (p<0.001) in cohorts A, B, and C, respectively. Median overall survival improved significantly over time: 14.4 months (95% confidence interval [CI], 12.0–16.8 months), 22.9 months (95% CI, 20.3–25.5 months), and 53.6 months (95% CI, 45.7–61.5 months) in cohorts A, B, and C, respectively. HBV-related patients showed significantly improved survival (12.7 vs. 20.4 vs. 64.5 months, p<0.001) associated with the use of antiviral treatments (adjusted hazard ratio, 0.72; 95% CI, 0.64–0.80). Conclusions The survival of patients with HCC, especially HBV-related HCC, has improved significantly over time in Korea.

Abstract
Objective To investigate the factors affecting a healthy diet in patients with gastric cancer. Methods Data from 146 consecutive patients with gastric cancer were collected based on the integrated model for behavior change. Core theory constructs were operationalized with decisional balance on a healthy diet, self-efficacy in fruit and vegetable (F&V) intake and diet planning, coping planning and self-leadership, and stages of change in F&V intake and adhering to a diet plan. Results Higher self-efficacy in F&V intake and diet planning were associated with a higher readiness for change in F&V intake (adjusted odds ratio [aOR] for self-efficacy, 1.02; 95% confidence interval [CI], 1.01–1.04) and for adhering to a diet plan (aOR for self-efficacy, 1.02; 95% CI, 1.01–1.04; aOR for diet planning, 1.02; 95% CI, 1.01–1.04). Coping planning was a determinant of readiness for change in F&V intake (aOR, 1.02; 95% CI, 1.01–1.04). Self-leadership in behavioral awareness and volition (aOR, 1.02; 95% CI, 1.01–1.03) and task motivation (aOR, 1.02; 95% CI, 1.00–1.03) were determinants of readiness for change in adhering to a diet plan. Conclusions Self-efficacy and coping planning were determinants of readiness for change in F&V intake in patients with gastric cancer. Self-efficacy and self-leadership were determinants of readiness for change in adhering to a diet plan in patients with gastric cancer. Improving self-efficacy, coping planning, and self-leadership is essential for changing behaviors to adopt a healthy diet. Nurses caring for patients with gastric cancer should identify strategies that improve self-efficacy in F&V intake and diet planning.

Abstract
BACKGROUND The incidence of thyroid nodules has increased dramatically in recent decades. Although this increase has been attributed to improved imaging modalities, the question arises as to whether other environmental factors, such as infectious agents are influential. METHODS Adult patients with newly diagnosed papillary thyroid carcinoma, benign thyroid nodules, and healthy euthyroid controls without nodules; were recruited. Various clinical and biochemical parameters including thyroid function tests and serum Parvovirus B19 Ab (IgG) were assessed and compared between groups. RESULTS In this study, data from 364 patients with papillary thyroid carcinoma, 370 patients with benign thyroid nodules, and 360 healthy euthyroid individuals without nodules were analyzed as a control group. The prevalence of parvovirus B19 infection in papillary thyroid carcinoma patients was 58.8% that was significantly higher than the two groups of benign thyroid nodules (49.2%) and the control group (45.0%). In the papillary thyroid carcinoma group, a significant positive correlation was found between tumor size and TSH (r = 0.129, p = 0.014), and between tumor size and B19-Ab (r = 0.176, p = 0.001). CONCLUSION The rate of parvovirus B19 infection was higher in patients with papillary thyroid carcinoma and benign thyroid nodules than in the control group. Also, patients with papillary thyroid carcinoma had significantly higher rates of B19 infection than those with benign thyroid nodules.

Abstract
STUDY DESIGN This was a retrospective study. OBJECTIVE This study aimed to investigate the prognosis and characteristics of patients undergoing surgical treatment for colorectal cancer (CRC) spinal metastasis. To better understand the characteristics of such patients, their results were compared with those with spinal metastasis from non-small cell lung cancer (NSCLC), as the prognosis of these patients is well-studied. SUMMARY OF BACKGROUND DATA CRC commonly metastasizes to the liver or lung, while spinal metastases occur infrequently. The literature contains very few studies evaluating the prognosis of patients with spinal metastases from CRC. MATERIALS AND METHODS A consecutive 155 patients who underwent surgical treatment for spinal metastases from CRC (n=35) or NSCLC (n=120) between 2010 and 2018 were included in this study. Data were collected throughout the disease course, including those concerning all cancer-related treatments for both the primary cancer and spinal metastasis. Categorical variables were divided into patient, tumor, and treatment factors, and postoperative survival times were compared between the CRC and NSCLC groups. RESULTS The mean interval from cancer diagnosis to spinal metastasis was significantly greater in CRC group (32.5 mo) than in NSCLC group (12.9 mo). Concurrent spinal metastasis was more common in NSCLC group than CRC group (45.0% vs. 17.2%; P=0.003). Visceral metastasis was found more frequently in CRC group than NSCLC group (77.1% vs. 42.5%; P<0.001). The proportion of patients undergoing postoperative systemic treatment was significantly higher in NSCLC group than CRC group (59.2% vs. 20.0%; P<0.001). Median survival time after spine surgery was 4.2 months in CRC group and 5.8 months in NSCLC group (P=0.015). CONCLUSIONS The prognosis after surgical treatment for CRC spinal metastasis was poor, and worse than that of NSCLC group. These results can be explained by the later development of spinal metastases and the limited chance of postoperative medical treatment in CRC spinal metastasis.

Abstract
OBJECTIVE To examine the association between Textbook Outcome (TO)-a new composite quality measurement-and long-term survival in gastric cancer surgery. BACKGROUND Single-quality indicators do not sufficiently reflect the complex and multifaceted nature of perioperative care in patients with gastric adenocarcinoma. METHODS All patients undergoing gastrectomy for nonmetastatic gastric adenocarcinoma registered in the Population Registry of Esophageal and Stomach Tumours of Ontario (PRESTO) between 2004 and 2015 were included. TO was defined according to negative margins; >15 lymph nodes sampled; no severe complications; no re-interventions; no unplanned ICU admission; length of stay ≤21 days; no 30-day readmission; and no 30-day mortality. Three-year survival was estimated using the Kaplan-Meier method. A marginal multivariable Cox proportional-hazards model was used to estimate the association between achieving TO metrics and long-term survival. E-value methodology was used to assess for risk of residual confounding. RESULTS Of the 1836 patients included in this study, 402 (22%) achieved all TO metrics. TO patients had a higher 3-year survival rate compared to non-TO patients (75% vs 55%, log-rank P < 0.001). After adjustments for covariates and clustering within hospitals, TO was associated with a 41% reduction in mortality (adjusted hazards ratio 0.59, 95% confidence interval 0.48, 0.72, P < 0.001). These results were robust to potential residual confounding. CONCLUSIONS Achieving TO is strongly associated with improved long-term survival in gastric cancer patients and merits further focus in surgical quality improvement efforts.

Abstract
Serial alcohol consumption causes alcoholic liver disease (ALD), which can lead to fatty liver, hepatitis, and cirrhosis. Terminalia ferdinandiana (Kakadu plum) is an indigenous fruit of Australia, which is utilized as a functional food. It is a commercially important antioxidant as it contains a more eloquent level of ascorbic acid than other oranges. In this study, we analyzed the chemical constituents of vitamin C, gallic acid, ellagic acid, and daidzin via High-performance liquid chromatography (HPLC) in the Kakadu plum from two different regions including the Northern Territory (NT) and Western Australia (WA), and compared their biochemical properties. The vitamin C content was much higher (almost 70%) in Kakadu plum (KKD) from the NT than WA. Moreover, ROS generation was inhibited significantly in HepG2 (human hepatoma) cells with the KKD-NT extract treatment when compared to the KKD-WA extract treatment. The cytotoxicity produced by ethanol was significantly suppressed in response to the treatment with both of the samples. In addition, our samples (KKD-NT and KKD-WA) increased the activity of two key enzymes involving alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) that metabolize ethanol. These results show the biochemical confirmation of the mechanism by which KKD exhibits its biological functions including relief from alcohol hangovers as well as protection of the liver cells by the suppression of ROS production and toxic insults.

Abstract
PURPOSE Previous studies have suggested the benefits of regular exercise in motivating the survivors of cancer; however, most survivors are insufficiently active, showing high rates of nonadherence to physical activity guidelines. Using the I-Change model, this study sought to determine the association of decisional balance and self-efficacy for exercise, planning, and self-leadership with the stages of change in exercise behavior among patients with stomach cancer. METHODS This cross-sectional study was conducted in February 2021 and included 145 patients diagnosed with primary stomach cancer via quota sampling in South Korea. Sociodemographics, comorbidity, decisional balance for exercise, self-efficacy for exercise, planning, self-leadership, and stages of change in exercise behavior were assessed. RESULTS Of the participants, 4% were in the precontemplation stage of exercise behavior, 10% contemplation, 37% preparation, 23% action, and 27% maintenance. The male sex (p = 0.043), higher self-efficacy for resisting relapse (p < 0.0001), higher coping planning (p = 0.029), and higher self-leadership for behavior awareness and volition (p = 0.023) were associated with more readiness for changes in exercise behavior. CONCLUSIONS From the results obtained using the I-Change model, self-efficacy for resisting relapse to previous habits, coping planning, and behavior awareness and volition were associated with more readiness for changes in exercise behavior. These findings may help reduce stomach cancer survivors' nonadherence to physical activity guidelines.

Abstract
Foregut surgery largely involves benign diseases, and not only malignant diseases. However, for foregut surgeons in Asia, this fact has not been extensively utilized in their clinical practice due to the high burden of gastric cancer surgery. Although the prevalence of gastroesophageal reflux disease (GERD) in Eastern Asia, including Korea, is increasing, antireflux surgery (ARS) is still a fairly rare procedure in Korea. ARS is effective as proton pump inhibitors and is cost-effective compared to continuous double-dose proton pump inhibitors in patients with severe GERD. Therefore, we should focus on ARS as a treatment option for GERD also in Asian population. Similarly, although bariatric/metabolic surgery is effective in weight reduction and diabetes mellitus (DM) remission in patients with morbid obesity or DM, bariatric/metabolic surgery is only performed in a limited number of patients. Given that the prevalence of obesity and DM is continuously increasing in Korea, bariatric/metabolic surgery should become an interest among Korean foregut surgeons and should be considered a treatment for obesity and DM. Furthermore, there are new surgical fields that can control both benign and malignant diseases. Oncometabolic surgery is a field under foregut surgery that treats both malignant and benign components of a condition, an example being the control of metabolic syndrome while performing gastric cancer surgery. Therefore, in future gastric cancer treatment, oncometabolic surgery can be applied to patients with gastric cancer accompanied by obesity or metabolic syndrome.

Abstract
Serum thyrotropin (TSH) level after thyroid surgery affects the prognosis of differentiated thyroid cancer (DTC). However, the effects of preoperative serum TSH levels on the prognosis of DTC remain contradictory. In this study, to better understand the relationship between preoperative TSH levels and the prognosis of DTC, we performed pattern analysis of prognostic factors of DTC according to preoperative serum TSH levels. We retrospectively reviewed the clinical records of patients who were diagnosed and treated for DTC at the Samsung Medical Center, between 1994 and 2016. We reviewed preoperative serum TSH levels and performed a pattern analysis with prognostic risk factors for DTC. For pattern analysis, TSH was divided into 10 groups of equal fractions (TSH decile). We found a linear association between preoperative TSH levels and extra-thyroidal extension and lymph node metastasis. However, primary tumor size and initial distant metastasis showed a bimodal peak, which was similar to the pattern of overall and disease-specific death. We found that preoperative TSH range which showed the lowest mortality rate was about 0.8 to 1.59 mIU/L, which are slightly lower normal TSH levels. Although there was no linear trend, the primary tumor size, initial distant metastasis, and mortality of DTC were closely related with preoperative TSH decile and they showed a bimodal pattern. The results obtained in this study provide additional information for understanding the association between preoperative TSH levels and DTC prognosis.

Healthcare (Basel) 2021; 9:1400. [PMID: 34683079 PMCID: PMC8535689 DOI: 10.3390/healthcare9101400] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 10/14/2021] [Accepted: 10/17/2021] [Indexed: 01/06/2023] Open
Abstract
Colorectal polyps are precursor lesions of colorectal cancer and are known to be associated with obesity, low physical activity, and unhealthy behavior. This cross-sectional study analyzed the prevalence of colorectal polyps based on cardiorespiratory fitness (CRF), muscle strength, and health behavior in older adults. Participants were asymptomatic and included 1024 men and 472 women aged 65-80 years who visited the health care center. Colonoscopy was performed under conscious sedation, and cardiorespiratory fitness was measured as the maximum oxygen uptake using gas analysis. Muscle strength was determined using isokinetic equipment, and physical activity, alcohol consumption, and smoking status were investigated using questionnaires. Waist circumference was measured at the thickest part of the middle of the abdomen. Logistic regression analysis was used to calculate the prevalence of colorectal polyps using odds ratios (ORs) based on the variables. The incidence of colorectal polyps was 65.2% in men and 48.5% in women. The ORs of colorectal polyps for obesity were 1.151 (95% confidence interval [CI], 1.010-2.291) and 1.178 (95% CI, 1.015-2.612) in men and women, respectively. The OR for colorectal polyps in male current smokers was 1.884. The ORs for low CRF were 1.985 and 1.841 in men and women, respectively, compared with high CRF. The prevalence of polyps increased with low muscle strength (men's OR 1.343 women's OR 1.440) and physical activity in both men (OR 1.693) and women (OR 1.861). In conclusion, lower CRF and muscle strength were associated with an increased prevalence of colorectal polyps in men and women. In both sexes, high waist circumference and low physical activity increased the prevalence of colorectal polyps.

Shim SH, Lim MC, Lee D, Won YJ, Ha HI, Chang HK, Cho H. Cause-specific mortality rate of ovarian cancer in the presence of competing risks of death: a nationwide population-based cohort study. J Gynecol Oncol 2021; 33:e5. [PMID: 34783208 PMCID: PMC8728665 DOI: 10.3802/jgo.2022.33.e5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 09/16/2021] [Accepted: 09/26/2021] [Indexed: 11/30/2022] Open
Abstract
Objective This nationwide cohort study aimed to evaluate the cause-specific mortality (probability of death by ovarian cancer, probability of death by other causes) under the competing risks of death in women with ovarian cancer. Methods The Korea Central Cancer Registry was searched to identify women with primary ovarian cancer diagnosed between 2006 and 2016. Epithelial ovarian cancer cases were identified using the International Classification of Diseases for Oncology 3rd edition. We estimated the cause-specific mortality according to age (<65 years, ≥65 years), stage (local, regional, and distant), and histology (serous, mucinous, endometrioid, clear cell, and others) under the competing risks framework; moreover, cumulative incidences were estimated. Results We included 21,446 cases. Cause-specific mortality continuously increased throughout 10 year follow-up. Compared with women aged <65 years, ovarian cancer-specific mortality (5-year, 28.9% vs. 61.9%; 10-year, 39.0% vs. 68.6%, p<0.001) and other cause mortality (5-year, 1.7% vs. 4.8%; 10-year, 2.8% vs. 8.2%, p<0.001) increased in women aged ≥65 years. This trend was consistent across all the stages and histological types. There was a substantial increase in competing risks from 1.1% in women aged <65 years to 8.0% in women aged ≥65 years in patients with early-stage (p<0.001) non-serous ovarian cancer (p<0.001). Conclusion Older age at diagnosis is associated with increasing ovarian cancer-specific mortality and competing risks. Given the substantial effect of competing risks on elderly patients, there is a need for assessment tools to balance the beneficial and harmful effects to provide optimal treatment. This nationwide cohort study analyzed 21,446 women with primary ovarian cancer to evaluate survival and cause-specific competing mortality. Older age was associated with increasing both ovarian cancer-specific mortality and competing risks. Increased awareness of competing mortality is required for the optimal treatment decisions in the elderly.

Abstract
The association between insulin resistance and thyroid carcinoma is controversial. We conducted this meta-analysis of association between insulin resistance and thyroid carcinoma. There were 14 studies included in this meta-analysis. Random-effect model was used to merge the weighted mean difference value of fasting serum insulin level and the pooled effect shows that the level of fasting serum insulin is higher in patients with thyroid carcinoma than those of controls (1.88, 95% CI 0.87 to 2.90, P=0.0003). Random-effect model was used to estimate the pooled weighted mean difference and it shows that thyroid carcinoma patients have a higher level of homeostasis model assessment of insulin resistance (HOMA-IR) than patients without thyroid carcinoma (0.54, 95% CI 0.29 to 0.78, P<0.0001). Fixed-effect model with the odds ratio of insulin resistance shows that insulin resistance could increase the risk of thyroid carcinoma 216% compared with participants without insulin resistance (3.16, 95% CI 2.09 to 4.77, P<0.0001). In conclusion, insulin resistance might be a risk factor for thyroid carcinoma.

Cancer Biol Med 2021; 19:j.issn.2095-3941.2020.0634. [PMID: 34486877 PMCID: PMC8832952 DOI: 10.20892/j.issn.2095-3941.2020.0634] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2020] [Accepted: 04/25/2021] [Indexed: 12/05/2022] Open
Abstract
This review will describe the global patterns and trends of colorectal cancer survival, using data from the population-based studies or cancer registration. We performed a systematic search of China National Knowledge Infrastructure (CNKI), Wanfang Data, PubMed, Web of Science, EMBASE, and SEER and collected all population-based survival studies of colorectal cancer (up to June 2020). Estimates of observed and relative survival rates of colorectal cancer by sex, period, and country were extracted from original studies to describe the temporal patterns and trends from the late 1990s to the early 21st century. Globally, 5-year observed survival rates were higher in Seoul, Republic of Korea (1993-1997; 56.8% and 54.3% for colon and rectum cancers, respectively), Zhejiang province (2005-2010; 52.9% for colon cancer), Tianjin (1991-1999; 52.5% for colon cancer), Shanghai (2002-2006; 50.0% for rectum cancer) of China, and in Japan (1993-1996, 59.6% for colorectal cancer). Five-year relative survival rates of colorectal cancer in the Republic of Korea (2010-2014), Queensland, Australia (2005-2012), and the USA (2005-2009) ranked at relatively higher positions compared to other countries. In general, colorectal cancer survival rates are improving over time worldwide. Sex disparities in survival rates were also observed in the colon, rectum, and colorectal cancers in most countries or regions. The poorest age-specific 5-year relative survival rate was observed in patients > 75 years of age. In conclusion, over the past 3 decades, colorectal cancer survival has gradually improved. Geographic variations, sex differences, and age gradients were also observed globally in colorectal cancer survival. Further studies are therefore warranted to investigate the prognostic factors of colorectal cancer.

Abstract
This research examines the spatial structure of a sample of breast cancer (BC) cases and their spatial interaction with contaminated areas in the Monterrey Metropolitan Area (MMA). By applying spatial statistical techniques that treat the space as a continuum, degrees of spatial concentration were determined for the different study groups, highlighting their concentration pattern. The results indicate that 65 percent of the BC sample had exposure to more than 56 points of PM10. Likewise, spatial clusters of BC cases of up to 39 cases were identified within a radius of 3.5 km, interacting spatially with environmental contamination sources, particularly with refineries, food processing plants, cement, and metals. This study can serve as a platform for other clinical research by identifying geographic clusters that can help focus health policy efforts.

A Novel One-Step Knife Approach Can Reduce the Submucosal Injection Time of Endoscopic Submucosal Dissection: A Single-Blinded Randomized Multicenter Clinical Trials. Gut Liver 2021; 16:gnl210103. [PMID: 34162769 PMCID: PMC8761916 DOI: 10.5009/gnl210103] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2021] [Revised: 04/16/2021] [Accepted: 04/21/2021] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND/AIMS : Endoscopic submucosal dissection (ESD) is a curative treatment modality for early gastric neoplasms; however, ESD can be a time-consuming process. To overcome this pitfall, we developed the one-step knife (OSK) approach, which combines an endoscopic knife and injection needle on a single sheath. We aimed to evaluate whether this approach could reduce the ESD procedure time. METHODS This single-blinded randomized multicenter trial at four tertiary hospitals from June 2019 to June 2020 included patients aged 19 to 85 years undergoing ESD. Patients were randomly assigned to two groups (OSK or conventional knife [CK]). The injection time, total procedure time, resected specimen size, submucosal fluid amount, degree of device satisfaction, and adverse events were evaluated and compared between groups. RESULTS Fifty-one patients were analyzed (OSK: 25 patients and CK: 26 patients). No baseline differences were observed between groups, with the exception of a higher portion of males in the OSK group. The mean injection time was significantly reduced in the OSK group (39.0 seconds) compared to that in the CK group (87.5 seconds, p<0.001). A decrease of more than 10 minutes in the total procedure time (18.0 minutes vs 28.1 minutes, p=0.055) in the OSK group compared to the CK group was observed. Second-look esophagogastroduodenoscopy revealed two delayed bleeding cases in the OSK group that were easily controlled by endoscopic hemostasis. CONCLUSIONS OSK reduced the injection time and showed a decrease in total procedure time compared with the CK approach. OSK can be a feasible tool for ESD, especially in difficult cases.

Abstract
Background The relapse and distant metastasis in colon adenocarcinoma (COAD) patients with a poor prognosis. Autophagy has gained increasing attention recently. Methods This study utilized univariate Cox analysis from the TCGA database to obtain 10 prognostic autophagy-related genes (ARGs). GO and KEGG functional annotation analysis suggested that the ARGs were significantly enriched in tumor metabolic processes. We verified the autophagy-related genes screened by TCGA clinical data. Then, we compared the expression of SERPINA1 in primary and metastatic tumor cells in the GEO database, and finally verified the relationship between SERPINA1 protein expression and prognosis with the CPTAC database. Results The ROC curves showed SERPINA1 had robust prediction capability in judging the prognosis and disease process compared with the other 4 ARGs and risk score in COAD. Clinical relationship analysis further indicated SERPINA1 was related to TMN stage, clinical-stage, OS, RFS, and DMFS in COAD. Besides, survival analysis presented that higher expression of SERPINA1 was significantly associated with the longer OS, RFS, or DMFS. Moreover, SERPINA1 protein was validated to be associated with OS, RFS, and DMFS through our own IHC and CPTAC database. Finally, we exploratoryly combined the SERPINA1 mRNA and SERPINA1 protein as a new index for prognostics. Conclusion This new combined index showed the highest prognostic value for OS, RFS, and DMFS, and had the potential to become a practical biomarker for prognosis.

Abstract
PURPOSE Little is known about the incidence of thyroid cancer in patients with obstructive sleep apnea (OSA). This study aimed to evaluate whether OSA is associated with the incidence of thyroid cancer based on the Korea National Health Insurance Service (KNHIS) database. METHODS This study was designed as a retrospective cohort data analysis of the KNHIS dataset. A total of 198,574 patients who were over 20 years of age and had been newly diagnosed with OSA between 2007 and 2014 were enrolled. A control group of 992,870 individuals was selected based on propensity score matching by age and sex. The mean follow-up duration was 4.5 ± 2.3 years. The primary endpoint was the incidence of newly diagnosed thyroid cancer. RESULTS The hazard ratio (HR) for thyroid cancer incidence among OSA patients compared to the control was 1.72 (95% confidence interval [CI] 1.60-1.84) based on Model 1 (not adjusted by any covariate) and 1.64 (95% CI 1.53-1.76) based on Model 2 (adjusted by income level, diabetes, hypertension, and dyslipidemia). Thyroid cancer incidence was significantly higher in male patients (HR = 1.93, 95% CI 1.74-2.12) than female ones (HR = 1.39, 95% CI 1.26-1.54). When compared by age, the HR of thyroid cancer was higher in middle-aged (40 ≤ age < 65 years) patients (HR = 1.68, 95% CI 1.55-1.83) than in young (20 ≤ age < 40 years, HR = 1.53, 95% CI 1.32-1.77) or old (65 ≤ age, HR = 1.28, 95% CI 0.94-1.74) patients. CONCLUSION OSA may increase the risk of developing thyroid cancer, especially in middle-aged men.

Lee MK, Oh J. Patient-Reported Outcomes of Regular Aerobic Exercise in Gastric Cancer. Cancers (Basel) 2021; 13:cancers13092080. [PMID: 33923080 PMCID: PMC8123334 DOI: 10.3390/cancers13092080] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2021] [Revised: 04/16/2021] [Accepted: 04/22/2021] [Indexed: 01/01/2023] Open
Abstract
Simple Summary The benefits of exercise for health-related quality of life (HRQOL) and depression in patients with gastric cancer remain unclear. Thus this research was suggested to examine the association between maintenance of regular aerobic exercise at a recommended level and depression and HRQOL in patients with gastric cancer during or after treatment. The findings indicated that exercise can have a synergistic effect on improvement in HRQOL via indirect positive effects on depression and direct effects on HRQOL in patients with gastric cancer. The findings of this research may add the evidence on the benefits of exercise for HRQOL and depression in patients with gastric cancer to the research community. Abstract The benefits of exercise for health-related quality of life (HRQOL) and depression in patients with gastrointestinal disease remain unclear, and studies on gastric cancer are scant. This study examines the association between the maintenance of regular aerobic exercise at a recommended level and depression and HRQOL in patients with gastric cancer during or after treatment. In this cross-sectional study, a face-to-face survey was used to collect data from 126 patients with primary gastric cancer during or after treatment in a tertiary acute-care hospital in Korea. Regular exercise was defined as regularly maintained aerobic exercise of at least moderate intensity consuming ≥4 metabolic equivalents for ≥150 min/wk for at least 6 months. Depression was measured using the 9-item version of the Patient Health Questionnaire, and HRQOL was assessed using the EORTC QLQ-C30. Patients who maintained aerobic exercise at a recommended level were less likely to have depression and more likely to have improved global QOL, as well as physical, role, and emotional functioning. Patients with depression were less likely to report improved global QOL and functioning. Thus, exercise can have a synergistic effect on improvement in HRQOL via indirect positive effects on depression and direct effects on HRQOL in patients with gastric cancer. Oncology nurses should encourage patients with gastric cancer who suffer from a depressive mood to set up and implement specific plans for practicing regular exercise, which can lead to an improvement in both depression and HRQOL.

Front Oncol 2021; 11:638701. [PMID: 33937040 PMCID: PMC8082099 DOI: 10.3389/fonc.2021.638701] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 03/12/2021] [Indexed: 01/01/2023] Open
Abstract
Background Thyroid cancer is one of the most common endocrine malignancies worldwide, and papillary thyroid cancer (PTC) is the most common pathologic type of thyroid cancer. SQSTM1/p62 activity mediates different biological functions. This study aimed to investigate the effect of SQSTM1/p62, a multifunctional receptor, on biological function and autophagy characteristics in the human PTC cell line TPC-1. Methods A total of 105 primary PTC samples and matched adjacent normal thyroid tissue samples were obtained to evaluate the expression of p62 in clinical patients. A similar p62 expression pattern was found in PTC cell lines and normal human thyroid follicular epithelial cells. To evaluate the effect of SQSTM1/p62 on TPC-1 cells, we constructed the p62 knockout cell line p62-KO-TPC-1. Cell proliferation, cell cycle, and cell apoptosis were analyzed by colony formation tests, Cell Counting Kit-8 (CCK-8) assays and flow cytometry in vitro. TPC-1 and p62-KO-TPC-1 human PTC cell lines in the logarithmic growth phase were subcutaneously implanted into BALB/c nude mice to verify their proliferation effect in vivo. Furthermore, western blotting and immunohistochemistry (IHC) were used to detect the expression of AKT/AMPK/mTOR signaling pathway-related proteins. Results Overall, p62 expression was higher in tumor tissues than in normal tissues in 73 of 105 PTC patients (69.5%). The expression level of p62 in the PTC cell line was higher than that in the normal thyroid cell line. Our data indicated that in vitro, p62 deficiency could decrease the number of colonies, inhibit cell growth and the cell cycle, and induce apoptosis. Tumor xenograft experiments in BALB/c nude mice corroborated these findings. Moreover, the molecular mechanism was explored by western blotting, and we found that the AMPK/AKT/mTOR pathway was involved. Conclusions The results indicate that p62 might mediate cell autophagy and apoptosis in TPC-1 cells via the AMPK/AKT/mTOR pathway and could be used as a potential therapeutic approach for PTC.

Association between Moving to a High-Volume Hospital in the Capital Area and the Mortality among Patients with Cancer: A Large Population-Based Cohort Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18073812. [PMID: 33917393 PMCID: PMC8061764 DOI: 10.3390/ijerph18073812] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Revised: 02/08/2021] [Accepted: 02/18/2021] [Indexed: 11/17/2022]
Abstract
This study aimed to identify the association between moving to a high-volume hospital and the mortality of patients with cancer living in the district. The study population comprised participants diagnosed with cancer within the past nine years (2004-2012). The final sample included 8197 patients with cancer, 3939 were males (48.1%), and 4258 were females (51.9%). A Cox proportional hazard model was used to estimate the hazard ratio (HR) for death. Confounding variables including sex, age, type of social security, income level, disability, and utilization volume were incorporated into the model. Among patients with cancer living in the district, 2874 (35.1%) used healthcare services in Seoul. About 10% (n = 834) of patients died during the follow-up period. The HR for death in females (HR: 0.68, 95% CI: 0.58-0.81) was lower than that in males. Additionally, the HR for the death of patients using healthcare services in Seoul (HR: 1.30, 95% CI: 1.11-1.53) was higher than those patients who did not use healthcare services in Seoul. Among patients utilizing services in the province, wealthier patients' survival probability was significantly higher than that of others. The cause of income differences should be identified, and accessibility to medical use of low-income families should be enhanced to prevent mortality of patients from cancer disparities.

[PMID: 33722523 DOI: 10.1016/j.clbc.2021.02.002] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 11/26/2020] [Accepted: 02/08/2021] [Indexed: 01/13/2023]
Abstract
BACKGROUND The differential diagnostic role of plasma developmental endothelial locus-1 (Del-1) was proposed in our previous study. Therefore the current study aimed to confirm the diagnostic role and explore the prognostic role of exosomal Del-1 in a prospective cohort of female patients with breast cancer. PATIENTS AND METHODS To determine the optimal sampling time for the postoperative Del-1 measurements, blood was serially collected on days 1, 3, 5, and 7 after surgery in 22 patients (cohort 1). Thereafter, 111 female patients with breast cancer were prospectively enrolled (cohort 2) to compare exosomal Del-1 levels before and after surgery. RESULTS Among the subsequent prospective cohort, 107 patients (96.4%) showed a high exosomal Del-1 level (optical density [OD] value > 0.5) at the time of diagnosis. Of these patients, 101 (94.6%) in this high-level group showed normalized Del-1 levels postoperatively, representing a significant difference (mean OD value, 1.232 vs. 0.196; P < .00001). High postoperative Del-1 level was significantly associated with a worse disease-free survival adjusted to the clinicopathological characteristics (hazard ratio, 24.0; P = .0011). CONCLUSION This study confirmed the normalization of exosomal Del-1 after surgery, indicating exosomal Del-1 as a potent diagnostic biomarker for breast cancer. In addition, because a high Del-1 level after surgery was associated with early relapse, this suggests exosomal Del-1 as a potential prognostic marker by identifying the existence of residual cancer.

Abstract
ABSTRACT Some studies have demonstrated an increased risk of prostate cancer in patients with obstructive sleep apnea (OSA). However, the relationship is unclear and the results are conflicting. This study aims to investigate associations between OSA and prostate cancer using the Korea National Health Insurance Service database.A total of 152,801 men (≥ 20 years of age) newly diagnosed with OSA between 2007 and 2014 were included. A control group of 764,005 subjects was selected using propensity score matching by age and sex. The mean follow-up time was 4.6 years (range 2.3-6.9). The primary endpoint was newly diagnosed prostate cancer. The prostate cancer hazard ratio (95% confidence interval) was calculated for patients with OSA and compared to the control group.The incidence of prostate cancer among patients with OSA was significantly higher than that in controls (1.34 [1.23-1.49]). In particular, the incidence of prostate cancer was highest in patients aged 40-65 years (1.51 [1.32-1.72]).This study provides additional evidence for a link between OSA and prostate cancer.

Abstract
BACKGROUND Studies have shown that radioactive iodine therapy (RAIT) affects the development of second cancer in thyroid cancer patients. The impact of other factors, such as dyslipidemia are not clear. METHODS A retrospective analysis of thyroid cancer patients with a 1,251,913 person-year follow-up was conducted using data from the Health Insurance Review and Assessment database in South Korea from January 2008 to December 2018. We investigated factors related to second cancer development using a nested case-control analysis to avoid length bias. RESULTS The overall risk of developing second cancer was higher in thyroid cancer patients than in the general population [standardized incidence ratio, 3.34; 95% confidence interval (CI) 3.30-3.39]. Second cancer incidence was higher in patients who received RAIT than in those who did not [odds ratio (OR) 1.130; 95% CI 1.094-1.169]. Moreover, the risk of second cancer was higher in patients with dyslipidemia than in those without dyslipidemia (OR 1.265; 95% CI 1.223-1.309). After adjustment for RAIT, the incidence of a second cancer was higher in patients with dyslipidemia than in those without dyslipidemia (OR 1.262; 95% CI 1.221-1.306). CONCLUSIONS The risk of second cancer development in patients with thyroid cancer appears to be high. Dyslipidemia may be associated with an increased risk of several types of second cancers.

Abstract
OBJECTIVE To investigate the association between thyroidectomy and suicide attempt. METHODS A nationwide population-based electronic medical records database of South Korea between January 1, 2009 and June 30, 2016 was used to investigate incidence rate ratios (IRRs) of suicide attempts and probable suicide attempts before and after thyroidectomy using a self-controlled case series design. RESULTS In 2,986 patients who attempted suicide or probable suicide, the IRRs of suicidal behaviors during risk periods one year before and after thyroidectomy were investigated. Generally, after thyroidectomy, there was no increase in IRR compared to the non-risk period. When data were analyzed according to thyroidectomy type, after partial thyroidectomy, IRR increased up to 1.43 (95% CI: 1.03-1.98, p=0.032) in the days 91-181 period. In the subgroup with major depressive disorder (MDD), the IRR increased up to 1.74 (95% CI: 1.21-2.51, p=0.003) before thyroidectomy, and increased up to 1.67 (95% CI: 1.16-2.41, p=0.006) after thyroidectomy. CONCLUSION Although the general risk of suicide attempt was not increased after thyroidectomy, patients with MDD showed increased risk of suicide attempt before and after thyroidectomy. These results suggest that suicidality should be evaluated when depressive symptoms are present in patients who have undergone thyroidectomy.

Abstract
Purpose A water-soluble variant of the artemisinin called artesunate, approved as an antimalarial agent, can induce cell death on various cancer cell types. We studied the mechanism of cell death of artesunate on HCT116 colorectal cancer cells. Methods We treated HCT116 colon cancer cells with artesunate, holo-transferrin, deferoxamine mesylate, ferrostatin, necrostatin-1, and YM155. We observed the growth inhibition of artesunate on HCT116 colon cancer cells by morphologic findings. Inhibition of cell growth was assessed by MTT (3-(4,5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide) assay and long-term growth inhibition by colony-forming assay. Apoptosis was investigated by flow cytometry and Western blot analysis. Results Artesunate inhibited the proliferation of HCT116 colon cancer cells effectively. Co-treatment with YM155, a specific survivin inhibitor, enhanced the artesunate-induced cell death. Co-treatment with the iron-chelating agent deferoxamine rescued artesunate induced cell death and increased long-term cell survival and proliferation. Conclusion In this study, we demonstrated that artesunate-induced cytotoxicity in HCT116 colon cancer cells by suppressing the expression of survivin and partially by ferroptosis. Our findings suggest that the co-treatment artesunate with YM155 can induce more potent cell death on HCT116 colon cancer cells and shows new insight for the treatment of colorectal cancer patients.

Abstract
Favorable prognostic factors were a civil servant medical benefit plan and higher education. Advanced disease was a significant prognostic factor for shorter survival. HIV/AIDS status was not a significant prognostic factor for longer survival.
Cervical cancer is one of the most common cancers of women. In Thailand, the incidence and death rate of cervical cancer are 18.1 and 5.7 per 100,000 women, respectively. Disease progresses faster in patients infected with human immunodeficiency virus (HIV) with acquired immune deficiency syndrome (AIDS). However, limited data are available for Thailand. Here we determined the prevalence of HIV/AIDS and identified factors affecting survival. We reviewed medical records of women infected with HIV with cervical cancer treated at Ramathibodi Hospital from 2007 through 2014. Demographic and clinical data were collected upon diagnosis. We used the Kaplan–Meier method and a Cox proportional hazards model to evaluate the association of overall survival (OS) with risk factors. The mean, median and range of ages at diagnosis of the 1,362 subjects were 53.9 years, 53.0 years and 20–94 years, respectively. The prevalence of HIV/AIDS in patients with cervical cancer was 2.3% and 5-year survival was 61.2%. Multivariable analysis revealed that favourable prognostic factors were a civil servant medical benefit plan and higher education. Advanced cervical cancer was a poor prognostic factor. Prognosis of women with stage III and IV cervical cancer was extremely poor (HR = 7.25 (95%CI: 4.39–11.98)) in stage III and HR = 20.57 (95%CI: 11.59–36.53) in stage IV). The 1-, 3-, and 5-year survival rates of patients with (74.2%, 67.6%, and 63.6%, respectively) or without (87.4%, 71.3% and 63.7%, respectively) HIV/AIDS were not significantly different.

Abstract
BACKGROUND Recognition of the importance of self-management (SM) for breast cancer survivors (BCSs) is increasing, but evidence from investigations of their needs focusing on SM is limited. OBJECTIVES The aim of this study was to explore the SM needs of BCSs who had completed treatment. METHODS Using a qualitative study design, we interviewed a focus group of 20 BCSs who underwent cancer therapy (mean time since diagnosis 3.4 years) at a university hospital in South Korea. Data were analyzed via conventional content analysis. RESULTS The focus group interviews revealed 10 subthemes that we organized into 5 themes about the posttreatment SM needs of BCSs: (1) symptom management needs, (2) emotional management needs, (3) information acquisition needs, (4) need for a relationship with healthcare providers, and (5) adaptation needs. Specifically, participants needed to acquire SM skills to relieve symptoms (eg, peripheral neuropathy, insomnia), deal with emotional problems (eg, fear of recurrence, anxiety, depression), and adapt to changes due to cancer treatment (eg, body image, lifestyle, and role changes). In particular, participants expressed a substantial need for a constructive relationship with healthcare providers who, by respecting and communicating with them, would help empower them. Participants placed a high value on building self-confidence for successful SM. CONCLUSIONS Our findings can contribute to the development of breast cancer survivorship care plans by emphasizing posttreatment SM. IMPLICATIONS FOR PRACTICE Future SM support intervention for BCSs after treatment should focus on training SM skills, enhancing the survivor-provider relationship, and building survivor self-confidence.

Abstract
The association between obstructive sleep apnea (OSA) and malignant brain tumors has yet to be fully investigated. Therefore, the purpose of this study was to elucidate the effect of OSA on brain tumor incidence based on the Korea National Health Insurance Service (KNHIS) dataset. The KNHIS data between 2007 and 2014 were analyzed, and the primary endpoint was newly diagnosed malignant brain tumor. A total of 198,574 subjects aged ≥ 20 years with newly diagnosed OSA were enrolled in the study, and 992,870 individuals were selected as a control group based on propensity score matching (PSM) by gender and age. The average follow-up duration was 4.8 ± 2.3 years. The hazard ratios (HRs) for brain tumor for patients with OSA were 1.78 (95% confidence interval [CI]: 1.42-2.21) in Model 1 (not adjusted with any covariate) and 1.67 (95% CI: 1.34-2.09) in Model 2 (adjusted for income level, diabetes, hypertension, dyslipidemia, and COPD). In subgroup analysis by gender, the odds ratios (OR) of OSA were 1.82 (95% CI: 1.41-2.33) in men and 1.26 (95% CI: 0.74-2.03) in women. The ORs were 1.97 (95% CI: 1.15-3.24) in the older (age ≥ 65 years) group, 1.66 (95% CI: 1.25-2.17) in the middle-aged (40 ≤ age < 65 years) group, and 1.41 (0.78-2.44) in the young (20 ≤ age < 40 years) group. In conclusion, OSA may increase the incidence of brain tumors.

Abstract
While obesity increases colorectal cancer incidence, there are inconsistent results in the prognostic role of obesity or body weight change on survival. This study investigated the prognostic impact of body weight and weight change in stage III or high risk stage II colon cancer patients. We used data from patients enrolled in the phase III AVANT trial. The AVANT trial investigated the efficacy of adding bevacizumab to standard adjuvant chemotherapy (FOFOX or XELOX). Weight change during the first 6 months of adjuvant chemotherapy was measured. Cox proportional hazard model was used to assess the prognostic influence of body weight and weight change. Among 3451 intention-to-treat population, body weight and weight change was measured in 3449 (99.9%) and 2455 (71.1%) patients, respectively. Among 2455 patients, 651 (26.5%) had weight gain over 5 kg and 179 (7.3%) had weight loss over 5 kg. Weight gain was more frequently observed in Asian and male. Neither baseline BMI nor weight change affected recurrence or survival in the Cox proportional hazard model.

Abstract
OBJECTIVES Little is known about time trends in the prognosis of gastric cancer (GC), since the introduction of new chemotherapeutic agents. This study aimed to analyze how the increased number of available chemotherapeutic options affected the prognosis of GC and which patient types benefited within in a large population. METHODS From a population-based cancer registry in Japan, 35,751 cases of GC were identified. Of these, 8214 cases were stage 4. The time trend for 3-year survival in stage 4 GC according to patient characteristics (age and tumor location) was estimated in relation to the introduction of new anticancer drugs. Multiple imputation was performed for sensitivity analysis to strengthen the missing data. In addition, we estimated the 5-year survival rate for distal-GC (DGC) and proximal-GC (PGC), and the hazard ratio (HR) was estimated by Cox proportional hazard model. RESULTS Improvement of overall survival was accelerated in stage 4 cases over time. The prognosis was improved from 11.4% to 13.2%, subsequent to the approval of several oncologic drugs since 2009. Younger patients were more likely to have improved survival rates in response to the increase in chemotherapy options (< 60-year-old, 5.4%: 60-70, 2.2%; 70-80, 0.3%) from 2007 to 2015. The HR for DGC vs. PGC was 1.11 (95% CI 1.08-1.15), and PGC showed a higher rate of improved outcomes (2.4% vs. 0.6%). CONCLUSIONS This analysis showed that improvement in the GC survival rate was accelerated by the introduction of new chemotherapeutic strategies and it was most evident among younger patients and in patients with PGC.

Abstract
Background/Aims The National Liver Cancer Surveillance Program (NLCSP) was established in 2003 to reduce the socioeconomic burden imposed by liver cancer (LC). We aimed to investigate the effectiveness of the NLCSP in South Korea with respect to survival benefits and cost, after adjusting for various confounding factors. Methods We used the National Health Insurance Service claims data linked with the NLCSP from 2004 to 2015. The Cox proportional hazard model and generalized linear model were used to determine the effects of the NLCSP on the early detection of LC, survival, and medical costs. Results From 2006 to 2010, 66,632 patients (surveillance group: 10,527 and no surveillance group: 56,105) newly diagnosed with LC were included in the study. The odds of the early detection of LC was 1.82 (95% confidence interval [CI], 1.73 to 1.93) times higher among patients who participated in the NLCSP once within the 2-year period prior to the diagnosis of LC than among those who did not participate in the surveillance program. The mortality rate of patients who participated in the NLCSP was 22.0% lower (hazard ratio, 0.78; 95% CI, 0.76 to 0.80) than that of those who did not participate. When compared with the group who did not participate in surveillance, the group who participated in the NLCSP had higher total medical costs; however, their cost per day was lower after adjustment during the follow-up period. Conclusions This study highlights the survival benefit in patients who participated in the NLCSP and the need for continuous improvements of the NLCSP in South Korea.

Abstract
Background Carbon monoxide (CO) poisoning is a suspected risk factor for stroke. However, the association between stroke occurrence and carbon monoxide poisoning remains unclear. This nationwide study in Korea analyzed the incidence of stroke in survivors of CO poisoning. Material/Methods In this nationwide, population-based longitudinal study, the database of the Health Insurance Review and Assessment Service was searched to identify patients diagnosed with CO poisoning from 2012 to 2018. Their incidence of ischemic and hemorrhagic strokes, the patterns of stroke incidences, the annual incidence rates in sequential time, the standardized incidence ratio (SIR), and the effects of hyperbaric oxygen therapy (HBOT) were analyzed. Results Of the 29 301 patients diagnosed with CO poisoning during the study period, 984 (3.36%) were diagnosed with stroke after CO poisoning, with approximately 50% occurring within 1 year after CO poisoning. The overall SIR for stroke was 19.49 (95% confidence interval [CI], 17.92–21.12) during the first year, decreasing to 5.64 (95% CI, 4.75–6.66) during the second year. Overall stroke hazard ratio (HR) in the patients admitted to the ICU for CO poisoning was 2.28 (95% CI, 1.19–2.27), compared with 2.35 (95% CI, 1.94–2.84) for ischemic stroke and 1.76 (95% CI, 1.11–2.78) for hemorrhagic stroke. Cumulative HRs did not differ between patients who were and were not treated with HBOT for stroke. Conclusions CO poisoning is a high-risk factor for the development of stroke, evidenced by high incidences of stroke after CO poisoning. Practical strategies for preventing stroke after CO poisoning are needed, because stroke after CO poisoning affects adults of almost all ages, significantly increasing their socioeconomic burden.

Abstract
Infection is a major cause of cancers. We estimated the economic burden of cancers attributable to infection in 2014 in Korea, where cancer causing infection is prevalent, but the economic burden of it has never been examined. Cancer patients were defined as those having made medical claims as recorded by the National Health Insurance Service, which is a mandatory insurance for all citizen. We multiplied the costs by the population-attributable fraction for each type of cancer. The study included direct and indirect costs, where direct costs comprised direct medical and non-medical costs of inpatients and outpatients, while indirect costs were estimated by identifying future income loss due to premature death, productivity loss during hospitalization/outpatient visits, and job loss. In 2014, there were 100,054 infection-related cancer patients, accounting for 10.7% of all Korean cancer cases for that year. Direct costs of cancers associated with infection stood at nearly USD 676.9 million, while indirect costs were much higher at USD 2.57 billion. The average expenditure of a typical patient was USD 32,435. Economic burden of cancers attributable to infection is substantial in Korea, accounting for 0.23% of the national gross domestic product and 1.36% of national healthcare expenditure in 2014.

Abstract
BACKGROUND/OBJECTIVES Early diagnosis of pancreatic ductal adenocarcinoma (PDAC) is important as PDAC can lead to mortality; however, no specific biomarker has been identified for its early diagnosis. We previously identified fibrinogen α chain as a promising biomarker for differentiating between patients with and without PDAC using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Here, we aimed to validate the clinical usefulness of serum fibrinogen as a biomarker for PDAC. METHODS From 2009 to 2011, blood samples of 67 PDAC patients and 43 healthy adults (controls) were prospectively collected. Serum fibrinogen levels and their clinical significances were evaluated. RESULTS Mean fibrinogen levels were significantly higher in the PDAC group than in the control group (3.08 ± 0.565 vs. 2.54 ± 0.249 log10 ng/mL, P < 0.001). In the receiver operating characteristic analysis, overall sensitivity, and specificity of serum fibrinogen levels for differentiating PDAC patients from control patients were 67.4% and 83.6%, respectively, with a 427-ng/mL cutoff value. Serum fibrinogen levels were significantly higher in PDAC patients with distant metastasis than in those without distant metastasis (3.38 ± 0.581 vs. 2.93 ± 0.499 log10 ng/mL, P = 0.002). Median overall survival was significantly longer in PDAC patients with low fibrinogen levels (<1000 ng/mL) than in those with high fibrinogen levels (≥1000 ng/mL) [489 days (95% confidence interval, 248.1-729.9) vs. 172 days (58.4-285.6) (P = 0.008)]. Although serum fibrinogen levels were poorly correlated with carbohydrate antigen 19-9 levels, these two biomarkers together predicted survival better. CONCLUSIONS Serum fibrinogen levels may be a useful biomarker for diagnosing and predicting PDAC prognosis.

Abstract
There is limited evidence on the relationships of preference for end-of-life life-sustaining treatments [LSTs] and diagnostic contexts like heart failure [HF] or cancer, and patient attitudes toward and perceived susceptibility to use advance directives [ADs]. Thus, this study aimed to compare attitudes and perceived susceptibility between HF patients and community-dwelling patients with cancer, and examine the associations of these variables with their preference for each LST (cardiopulmonary resuscitation [CPR], ventilation support, hemodialysis, and hospice care). Secondary data were obtained from 36 outpatients with HF (mean age, 65.44 years; male, 69.4%) and 107 cancer patients (mean age, 67.39 years; male, 32.7%). More patients with HF preferred CPR than cancer patients (41.7% and 15.9%, χ2 = 8.88, P = 0.003). Attitudes and perceived susceptibility were similar between the two diagnostic cohorts. HF patients and those with more positive attitudes had greater odds of preferring CPR (odds ratio [OR] = 3.02, confidence interval [CI] = 1.19, 7.70) and hospice care (OR = 1.14, CI = 1.06, 1.23), respectively. HF diagnosis and AD attitudes increased the preference for CPR and hospice care, respectively. This suggests that it is important to gain positive attitudes toward ADs and consider diagnostic context to facilitate informed decision-making for LSTs.

Abstract
Objectives: We determined the surgical and oncological outcomes of laparoscopic nephroureterectomy (LNU) in comparison to open nephroureterectomy (ONU) and factors predicting bladder recurrence after nephroureterectomy. Methods: We retrospectively reviewed and compared the data of patients who underwent ONU or LNU for non-metastatic, upper-tract urothelial carcinoma from 2000 to 2016. The primary endpoint was to determine bladder cancer recurrence-free survival (BCRFS), cancer-specific survival (CSS), and overall survival (OS). The data were analysed using Student’s t-test, Chi-square test, and Kaplan-Meier curve. Results: Total of 50 patients, of which 24 had LNU and 26 had ONU, met the inclusion criteria. Median durations of follow-up were 4.2 and 6.5 years (p=0.1070) in LNU and ONU, respectively. Operative time, blood loss and hospital stay were significantly lower in the LNU group than in the ONU group (p=0.0001, p=0.0001, p=0.0018). Cancer-specific survival rate in the LNU was 75% and ONU was 73.3% (p=0.1902), whereas BCRFS and CSS were not significantly different in both groups (log-rank test; BCRFS: p=0.809 and CSS: p=0.802). Patients who underwent ureteroscopy with biopsy (p=0.001), had multifocality (p=0.001) and previous history of (H/O) bladder cancer (p=0.020) were at significant risk for developing bladder cancer recurrence after nephroureterectomy. Conclusion: Laparoscopic nephroureterectomy can benefit patients because of its minimal invasiveness, and oncologic outcomes are comparable to ONU. Preoperative ureteroscopy with biopsy, multifocality and previous H/O bladder cancer might be risk factors for bladder cancer recurrence.

Regorafenib in previously treated advanced hepatocellular carcinoma: Impact of prior immunotherapy and adverse events. Liver Int 2020; 40:2263-2271. [PMID: 32449588 DOI: 10.1111/liv.14496] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Revised: 04/15/2020] [Accepted: 04/25/2020] [Indexed: 02/13/2023]
Abstract
BACKGROUND & AIMS Regorafenib demonstrated a clinical benefit for patients with unresectable hepatocellular carcinoma (uHCC) in the phase III RESORCE trial. Considering the heterogeneity of uHCC and discrepancies in its characteristics between prospective trials and daily practice, real-life evidence is necessary. METHODS This multicentre, retrospective analysis was performed by the Korean Cancer Study Group. In total, 440 patients who received regorafenib between January 2017 and November 2019 were identified in nine tertiary referral hospitals in Korea. RESULTS All patients received prior sorafenib, and the median time-to-progression (TTP) on sorafenib was 3.9 months (range, 0.2-71.6). Regorafenib was used as the second, third and fourth to seventh lines of therapy in 305 (69.3%), 115 (26.1%) and 20 (4.5%) patients respectively. According to the RECIST v1.1, the overall response rate was 7.7% (n = 34), and the median progression-free survival (PFS) and overall survival (OS) were 3.2 (95% CI, 2.8-3.5) and 12.1 (95% CI, 9.7-14.5) months respectively. Immune checkpoint inhibitors (ICIs) were given in 115 patients (26.1%) prior to regorafenib. There were no differences in PFS and OS with regorafenib according to the prior use of ICIs (PFS, P = .61; OS, P = .63). The occurrence of hand-foot skin reaction (HFSR) was associated with a better OS (P < .001). CONCLUSIONS The real-life clinical outcomes of regorafenib for patients who progressed on prior systemic therapy including ICIs were consistent with the phase III trial results. HFSR was significantly associated with better OS with regorafenib.

Lee J, Shin A, Choi JY, Kang D, Lee JK. Adherence to the Recommended Intake of Calcium and Colorectal Cancer Risk in the HEXA Study. Cancer Res Treat 2020; 53:140-147. [PMID: 32854492 PMCID: PMC7812010 DOI: 10.4143/crt.2020.480] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Accepted: 08/24/2020] [Indexed: 12/31/2022] Open
Abstract
Purpose Dietary calcium intake has been suggested to be protective against the development of colorectal cancer. The mean dietary calcium intake of Koreans is 490 mg/day, which is far below the recommended calcium intake of 700-800 mg/day. In this study, we explored the relationship between dietary calcium intake and colorectal cancer development in Koreans with relatively low calcium intake compared with individuals in Western countries. Materials and Methods The Health Examinees Study, a large-scale genomic community-based prospective cohort study, was designed to identify the general characteristics of major chronic diseases in Koreans. A total of 119,501 participants aged 40-69 years recruited between 2004 and 2013 were included in this analysis. The calcium intake level was categorized using the Dietary Reference Intakes for Koreans (KDRIs). The Cox proportional hazards regression model was used to estimate the hazard ratio (HR) and the corresponding 95% confidence intervals (CIs) for colorectal cancer risk, adjusting for potential confounders. Results In the multivariable-adjusted model, compared with the group that consumed less than the recommended amount of calcium, the group that consumed more than the recommended intake of calcium showed a significant reduction in the risk of colorectal cancer in women. (HR, 0.54; 95% CI, 0.31 to 0.95). Among men, however, no significant association was observed between dietary calcium intake and colorectal cancer risk (HR, 0.89; 95% CI, 0.54 to 1.45). Conclusion Korean women who adhere to the recommended intake of calcium showed a reduced risk of colorectal cancer.

Multi-Grain Rice Diet Decreases Risk of Breast Cancer in Korean Women: Results from the Health Examinees Study. Nutrients 2020; 12:nu12082273. [PMID: 32751310 PMCID: PMC7468941 DOI: 10.3390/nu12082273] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Revised: 07/23/2020] [Accepted: 07/24/2020] [Indexed: 12/24/2022] Open
Abstract
Although a number of studies explain the association between dietary patterns, which take into account that foods are eaten in combination, and breast cancer risk, the findings are inconsistent. We examined the association between dietary patterns and multi-grain rice intake, and the risk of breast cancer in a large-scale prospective cohort study in Korean women. A total of 93,306 women aged 40–69 years from the Health Examinees-Gem (HEXA-G) study (2004 and 2013) were included. We obtained Information on cancer diagnosis via linkage to the Korea Central Cancer Registry. Factor analysis was conducted to obtain dietary patterns, and Cox proportional models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (95% CI) for breast cancer risk. For 494,490 person-years, 359 new cases of breast cancer occurred. We identified three major dietary patterns, that explained 23.9% of the total variance based on daily total food intake (g/day) from 37 food groups: the meat dietary pattern (higher intake of bread and red meat), the white rice dietary pattern (higher intake of white rice and lower intake of multi-grain rice), and the other pattern. Women who had higher white rice dietary pattern scores had a 35% higher risk of breast cancer, than did women with lower white rice dietary pattern scores (multivariable HR 1.35; 95% CI 1.00–1.84 for the highest vs. lowest quartile of the white rice dietary pattern scores, p for trend = 0.0384). We found that women who consumed three or more servings of multi-grain rice per day had 33% lower risk of breast cancer than did those who consumed one or less multi-grain rice serving per day among women under 50 years of age (multivariable HR 0.67; 95% CI 0.45–0.99, p for trend = 0.0204). Our study suggests that a multi-grain rice diet may be associated with lower risk of breast cancer in Korean women.
