Cancer incidence among male construction workers in Korea: a standardized incidence ratio analysis, 2009-2015.	OBJECTIVES: Construction workers face an elevated risk for several types of cancer. Nevertheless, there is a lack of large-scale epidemiological studies examining the risk of all cancers in construction workers. This study aimed to investigate the risk of various cancers in male construction workers using the Korean National Health Insurance Service (NHIS) database. METHODS: We used data from the NHIS database from 2009 to 2015. Construction workers were identified using the Korean Standard Industrial Classification code. We calculated the age-standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) for cancer occurrence in male construction workers compared to all male workers. RESULTS: Compared to all male workers, the SIRs for esophageal cancer (SIR, 1.24; 95% CI, 1.07 to 1.42) and malignant neoplasms of the liver and intrahepatic bile ducts (SIR, 1.18; 95% CI, 1.13 to 1.24) were significantly higher in male construction workers. The SIRs for malignant neoplasms of the urinary tract (SIR, 1.19; 95% CI, 1.05 to 1.35) and non-Hodgkin lymphoma (SIR, 1.21; 95% CI, 1.02 to 1.43) were significantly elevated in building construction workers. The SIR for malignant neoplasms of the trachea, bronchus, and lung (SIR, 1.16; 95% CI, 1.03 to 1.29) was significantly higher in heavy and civil engineering workers. CONCLUSIONS: Male construction workers have an increased risk for esophageal cancer, liver cancer, lung cancer, and non- Hodgkin's cancer. Our results indicate that tailored strategies for cancer prevention should be developed for construction workers.	esophagus
Exosomal PIK3CB promotes PD-L1 expression and malignant transformation in esophageal squamous cell carcinoma.	Esophageal squamous cell carcinoma (ESCC), which accounts for 90% of esophageal carcinomas, seriously endangers human health. Worse still, the 5-year overall survival of ESCC is approximately 20%. Elucidation of the potential mechanism and exploration of promising drugs for ESCC are urgently needed. In this study, a high level of exosomal PIK3CB protein was found in the plasma of ESCC patients, which might indicate a poor prognosis. Moreover, a significant Pearson's correlation was observed at the protein level between exosomal PIK3CB and exosomal PD-L1. Further study revealed that cancer cell-intrinsic and exosome-derived PIK3CB promoted the transcriptional activity of the PD-L1 promoter in ESCC cells. Moreover, treatment with exosomes with lower levels of exosomal PIK3CB decreased the protein level of the mesenchymal marker β-catenin while increasing that of the epithelial marker claudin-1, indicating the potential regulation of epithelial-mesenchymal transition. Consequently, the migratory ability and cancer stemness of ESCC cells and the growth of tumors formed by ESCC cells were decreased with the downregulation of exosomal PIK3CB. Therefore, exosomal PIK3CB plays an oncogenic role by promoting PD-L1 expression and malignant transformation in ESCC. This study may provide new insight into the inherent biological aggressiveness and the poor response to currently available therapies of ESCC. Exosomal PIK3CB may be a promising target for the diagnosis and therapy of ESCC in the future.	esophagus
The impact of preoperative waiting time in Stage II-III gastric or gastroesophageal junction cancer: A population-based cohort study.	BACKGROUND: Gastrectomy remains the curative option in gastric cancer. However, the growing concern that preoperative waiting jeopardizes survival has not been fully addressed. The present population-based cohort study aimed to clarify the impact of preoperative waiting time (PreWT). METHODS: We included patients with clinical Stage II-III gastric cancer who received curative surgery from 2008 to 2017 of Taiwan Cancer Registry. PreWT was defined as the time from endoscopic diagnosis to surgery. The prognostic impact on overall survival (OS) was evaluated with Cox and restricted cubic spline regressions. RESULTS: A total of 3059 patients with a median age of 68 years were evaluated. The median PreWT was 16 days (interquartile range, 11-24 days), and patients with a shorter PreWT were younger, had a more advanced disease and received adjuvant therapies. Despite a shorter OS occurring with prolonged PreWT (median OS by PreWT [days]: 7-13, 2.7 years; 14-20, 3.1 years; 21-27, 3.0 years; 28-34, 4.7 years; 35-31, 3.7 years; 42-48, 3.4 years; 49-118, 2.8 years; p = 0.029), the differences were not significant after adjustment. The Cox and restricted cubic spline regressions showed that prolonged PreWT was not a significant prognostic factor for OS (p = 0.719). CONCLUSIONS: The population-based study suggests that a PreWT of 49-118 days does not independently correlate with a poor prognosis in Stage II-III gastric cancer. The study provides rationale for a window period for preoperative therapies and patient optimization.	esophagus
OPLAH Protein Expression Stratifies the Prognosis of Patients With Squamous Cell Carcinoma of the Esophagus.	BACKGROUND/AIM: Squamous cell carcinoma is one of the major subtypes of esophageal carcinoma, and the 5-year overall survival rate of esophageal squamous cell carcinoma patients who underwent curative treatment remains below 40%. We aimed to detect and validate the prognosticators of esophageal squamous cell carcinoma in patients who underwent radical esophagectomy. MATERIALS AND METHODS: Comprehensive analysis of transcriptome and clinical data from The Cancer Genome Atlas revealed OPLAH as one of the differentially expressed genes between esophageal squamous cell carcinoma tissues and normal esophageal mucosa. OPLAH expression changes were significantly associated with a patient prognosis. OPLAH protein levels were further evaluated by immunohisto-chemistry in esophageal squamous cell carcinoma tissues (n=177) as well as in serum samples (n=54) using ELISA. RESULTS: OPLAH mRNA was significantly overexpressed in esophageal squamous cell carcinoma tissues compared to normal esophageal mucosa, and patients with high OPLAH mRNA expression have a significantly poorer prognosis, according to The Cancer Genome Atlas data. The high staining intensity of OPLAH protein in esophageal squamous cell carcinoma tissue clearly stratified patient prognosis. According to multivariable analysis, high OPLAH protein expression was an independent prognostic factor for survival after surgery. Pre-neoadjuvant chemotherapy serum OPLAH protein concentrations were significantly associated with clinical tumor depth and node positivity and, consequently, with advanced clinical stage. The serum OPLAH protein concentration was significantly decreased by neoadjuvant chemotherapy. CONCLUSION: OPLAH protein expression in cancerous tissue and serum may have clinical utility towards stratifying prognosis of patients with esophageal squamous cell carcinoma.	esophagus
TBX18 knockdown sensitizes esophageal squamous cell carcinoma to radiotherapy by blocking the CHN1/RhoA axis.	OBJECTIVE: Radioresistance is a challenge in the effective treatment of esophageal squamous cell carcinoma (ESCC). Herein, this research ascertained whether TBX18 reduced the radiosensitivity of ESCC. METHODS: Bioinformatics analysis was utilized to retrieve differentially expressed genes. Then, the expression of corresponding candidate genes was tested using qRT-PCR in ESCC clinical specimens, and TBX18 was selected for subsequent experiments. The binding between TBX18 and CHN1 was evaluated by dual-luciferase reporter and ChIP assays, and the relationship between CHN1 and RhoA was identified by GST pull-down. Ectopic expression or knockdown experiments and radiation treatment were performed in cells and the nude mouse xenograft model to clarify the impacts of TBX18, CHN1, and RhoA on radiosensitivity in ESCC. RESULTS: Bioinformatics analysis and qRT-PCR retrieved upregulated TBX18 in ESCC for the follow-up study. Additionally, TBX18 was positively correlated with CHN1 in ESCC clinical specimens. Mechanistically, TBX18 bound to the CHN1 promoter region to transcriptionally activate CHN1, thus elevating RhoA activity. Moreover, TBX18 knockdown reduced ESCC cell proliferation and migration while augmenting their apoptosis after radiation, which was negated by further overexpressing CHN1 or RhoA. CHN1 or RhoA knockdown diminished ESCC cell proliferation and migration, as well as enhanced cell apoptosis, subsequent to radiation. Likewise, TBX18 overexpression increased ESCC cell autophagy after radiation, which was partially reversed by knockdown of RhoA. The results of in vivo xenograft experiments in nude mice were concurrent with the in vitro results. CONCLUSION: TBX18 knockdown lowered CHN1 transcription and thus reduced RhoA activity, which sensitized ESCC cells to radiotherapy.	esophagus
Statin use and its association with decreased risk of esophageal squamous cell carcinoma in betel nut chewers.	BACKGROUND: Betel nut chewing involves the chewing of areca nuts or betel quid (areca nuts wrapped in betel leaves), which is associated with an increased risk of esophageal squamous cell carcinoma (ESCC). Statins have anticancer properties. We investigated the association between statin use and ESCC risk in betel nut chewers. METHODS: The study included 105 387 betel nut chewers matched statin users and nonusers. Statin use was defined as the use of ≥28 cumulative defined daily doses (cDDDs) of statin. The primary outcome was incidence of ESCC. RESULTS: The incidence rate of ESCC was significantly lower in statin users than in nonusers (2.03 vs. 3.02 per 100 000 person-years). Statin users had a lower incidence rate ratio of 0.66 for ESCC (95% confidence interval [CI]: 0.43-0.85) relative to nonusers. After potential confounders were adjusted for, statin use was determined to be associated with a reduced risk of ESCC (adjusted hazard ratio [aHR], 0.68; 95% CI: 0.51-0.91). A dose-response relationship was observed between statin use and ESCC risk; the aHRs for statin use at 28-182 cDDDs, 183-488 cDDDs, 489-1043 cDDDs, and > 1043 cDDDs were 0.92, 0.89, 0.66, and 0.64, respectively. CONCLUSION: Statin use was revealed to be associated with a reduced risk of ESCC in betel nut chewers.	esophagus
Esophageal cancer patients' need for information and support in making a treatment decision between standard surgery and active surveillance.	BACKGROUND: This study explores patients' need for information and support in deciding on esophageal cancer treatment, when experimental active surveillance and standard surgery are both feasible. METHODS: This psychological companion study was conducted alongside the Dutch SANO-trial (Surgery As Needed for Oesophageal cancer). In-depth interviews and questionnaires were used to collect data from patients who declined participation in the trial because they had a strong preference for either active surveillance (n = 20) or standard surgery (n = 20). Data were analyzed using both qualitative and quantitative techniques. RESULTS: Patients prefer to receive information directly from their doctors and predominantly rely on this information to make a treatment decision. Other information resources are largely used to confirm their treatment decision. Patients highly value support from their loved ones and appreciate emphatic doctors to actively involve them in the decision-making process. Overall, patients' needs for information and support during decision-making were met. CONCLUSIONS: The importance of shared decision-making and the role doctors have in this process is underlined. The role of doctors is essential at the initial phase of decision-making: Once patients seem to have formed their treatment preference for either active surveillance or surgery, the influence of external resources (including doctors) may be limited.	esophagus
The feasibility of post-photodynamic therapy salvage esophagectomy in patients with esophageal squamous cell carcinoma treated with definitive chemoradiotherapy.	BACKGROUND: Photodynamic therapy (PDT) is a minimally invasive salvage treatment for local residual or recurrent lesions that persist after the definitive chemoradiotherapy (dCRT) of esophageal cancer. However, esophageal cancer persistence after PDT is associated with a poor prognosis. Although esophagectomy is a curative treatment option, few studies have evaluated its efficacy. Thus, this study aimed to evaluate the outcomes of salvage esophagectomy after PDT. METHODS: 14 patients who underwent salvage esophagectomy for residual or recurrent esophageal cancer after PDT between April 2006 and November 2022 at our institution, were enrolled. The short-term (e.g., blood loss, operative time, R0 rate, postoperative complications, and postoperative hospital stay) and long-term (e.g., overall survival [OS] and recurrence-free survival [RFS]) of salvage esophagectomy after PDT were evaluated retrospectively. RESULTS: The median operative time and intraoperative blood loss were 355 min and 350 ml, respectively. Eight patients (57.1%) had postoperative complications of Clavien-Dindo grade II or more. The median postoperative hospital stay was 20.5 days. The 3-year OS and RFS rates were 23.5% (95% confidence interval [CI] 5.7-48.0) and 16.3% (95% CI 2.7-40.3), respectively. Seven patients with an R0 had significantly longer OS than the seven patients with R1 and 2 (p = 0.045). The 3-year OS rate for patients with R0 was 52.6%. CONCLUSIONS: Although salvage esophagectomy after PDT carries certain risks, patients who achieved an R0 had a promising long-term prognosis. The location and size of the lesion may be critical factors in determining whether R0 can be achieved with salvage esophagectomy after PDT.	esophagus
Age-specific cardiovascular disease-related mortality among patients with major gastrointestinal cancers: A SEER population-based study.	BACKGROUND: Studies have reported age as a risk factor for cardiovascular disease (CVD)-related mortality; however, only a few studies have focused on the relationship between age and CVD-related mortality, especially among major gastrointestinal cancers. METHOD: The present retrospective cohort enrolled patients with colorectal, pancreatic, hepatocellular, gastric, and esophageal cancer between 2000 to 2015 from the Surveillance, Epidemiology and End Results Registry (SEER). Standardized mortality ratio (SMR), competing risk regression, and restricted cubic spline (RCS) analyses were used in our study. RESULTS: We analyzed 576,713 patients with major gastrointestinal cancers (327,800 patients with colorectal cancer, 93,310 with pancreatic cancer, 69,757 with hepatocellular cancer, 52,024 with gastric cancer, and 33,822 with esophageal cancer). Overall, CVD-related mortality gradually decreased every year, and the majority were older patients. All cancer patients had a higher CVD-related mortality rate than the general U.S. POPULATION: The adjusted sub-hazard ratios for middle-aged with colorectal cancer, pancreatic cancer, hepatocellular cancer, gastric cancer, and esophageal cancer were 2.55 (95% CI: 2.15-3.03), 1.77 (95% CI: 1.06-2.97), 2.64 (95% CI: 1.60-4.36), 2.15 (95% CI: 1.32-3.51), and 2.28 (95% CI: 1.17-4.44), respectively. The adjusted sub-hazard ratios for older patients with colorectal cancer, pancreatic cancer, hepatocellular cancer, gastric cancer, and esophageal cancer were 11.23 (95% CI: 9.50-13.27), 4.05 (95% CI: 2.46-6.66), 4.47 (95% CI: 2.72-7.35), 7.16 (95% CI: 4.49-11.41), and 4.40 (95% CI: 2.28-8.48), respectively. A non-linear relationship between age at diagnosis and CVD-related mortality was found in colorectal cancer, pancreatic cancer, and esophageal cancer; their reference ages were 67, 69, and 66 years old, respectively. CONCLUSION: This study demonstrated that age was a risk factor for CVD-related mortality among major gastrointestinal cancers.	esophagus
Long-term survival and prognostic factors associated with curative conversion surgery for ct4b esophageal squamous cell carcinoma: Analysis of 200 consecutive cases.	BACKGROUND: The optimal treatment strategy for cT4b esophageal cancer has not been established yet. Although curative surgery is sometimes performed after induction treatments, the prognostic factor of cT4b esophageal cancer cases who underwent R0 resection remains unknown. METHODS: A total of 200 patients with cT4b esophageal cancer who underwent R0 resection after induction treatments between 2001 and 2020 in our institute were included in the present study. The relationship between clinicopathological factors and patient survival is evaluated to identify useful prognostic factors. RESULTS: The median and 2-year overall survival were 40.1 months and 62.8%, respectively. Disease recurrence occurred in 98 (49%) patients after surgery. Compared to induction chemotherapy alone, chemoradiation-based induction treatments were associated with decreased locoregional recurrence (34.0% vs 60.8%, P = .0077) but increased pulmonary metastases (27.7% vs 9.8%, P = .0210) and dissemination (19.1% vs 3.9%, P = .0139) after surgery. Multivariate analysis of overall survival identified the preoperative C-reactive protein/albumin ratio (hazard ratio 1.7957, P = .0031), response to induction treatments (hazard ratio 2.9663, P = .0009), postoperative pneumonia (hazard ratio 2.3784, P = .0010), and pN (2-3) (hazard ratio 1.5693, P = .0355) as independent prognostic factors. Preoperative C-reactive protein/albumin ratio (hazard ratio 1.6760, P = .0068) and postoperative pneumonia (hazard ratio 1.8365, P = .0200) were also independent prognostic factors for recurrence-free survival. CONCLUSION: Curative surgery after induction therapy for cT4b esophageal cancer achieved favorable survival. Preoperative C-reactive protein/albumin ratio, postoperative pneumonia, response to induction treatments, and pN were useful prognostic factors.	esophagus
Prognostic value of pre-therapeutic nutritional risk factors in elderly patients with locally advanced esophageal squamous cell carcinoma receiving definitive chemoradiotherapy or radiotherapy.	BACKGROUND: The nutritional status of cancer patients is a crucial factor in determining their prognosis. The objective of this study was to investigate and compare the prognostic value of pretreatment nutrition-related indicators in elderly esophageal squamous cell carcinoma (ESCC). Risk stratification was performed according to independent risk factors and a new nutritional prognostic index was constructed. METHODS: We retrospectively reviewed 460 older locally advanced ESCC patients receiving definitive chemoradiotherapy (dCRT) or radiotherapy (dRT). This study included five pre- therapeutic nutrition-related indicators. The optimal cut-off values for these indices were calculated from the Receiver Operating Curve (ROC). Univariate and multivariate COX analyses were employed to determine the association between each indicator and clinical outcomes. The predictive ability of each independently nutrition-related prognostic indicator was assessed using the time-dependent ROC (time-ROC) and C-index. RESULTS: Multivariate analyses indicated that the geriatric nutrition risk index (GNRI), body mass index (BMI), the controlling nutritional status (CONUT) score, and platelet-albumin ratio (PAR) could independently predict overall survival (OS) and progression-free survival (PFS) in elderly patients with ESCC (all p < 0.05), except for prognostic nutritional index (PNI). Based on four independently nutrition-related prognostic indicators, we developed pre-therapeutic nutritional prognostic score (PTNPS) and new nutritional prognostic index (NNPI). No-risk (PTNPS = 0-1 point), moderate-risk (PTNPS = 2 points), and high-risk (PTNPS = 3-4 points) groups had 5-year OS rates of 42.3%, 22.9%, and 8.8%, respectively (p < 0.001), and 5-year PFS rates of 44.4%, 26.5%, and 11.3%, respectively (p < 0.001). The Kaplan-Meier curves showed that the mortality of elderly ESCC patients in the high-risk group was higher than that in the low-risk group according to the NNPI. Analysis of time-AUC and C-index revealed that the NNPI (C-index: 0.663) had the greatest predictive power on the prognosis in older ESCC patients. CONCLUSIONS: In elderly ESCC patients, the GNRI, BMI, CONUT score, and PAR can be used as objective assessment measures for the risk of nutrition-related death. Compared to the other four indexes, the NNPI has the greatest prognostic value for prognosis, and elderly patients with a higher nutritional risk have a poor prognosis, which is helpful in guiding early clinical nutrition intervention.	esophagus
Assessing the Role of Perioperative Nutritional Education in Improving Oral Intake after Oesophagectomy: A Retrospective Study.	BACKGROUND: This study aimed to determine whether nutritional education, from the preoperative to postoperative period, and nutritional management designed to improve nutritional status alone, could improve patients' health-related self-management and nutritional management skills during the postoperative period. METHODS: We evaluated 101 hospitalised patients with oesophageal cancer who underwent surgery between 2015 and 2016 and received perioperative nutritional education (PERIO-N). The control group included 52 patients who underwent surgery between 2014 and 2015 and were supported only by normal interventions according to the Enhanced Recovery After Surgery protocol. The PERIO-N group paid specific attention to nutrition risk screening, nutrition assessment, nutrition monitoring, and lifestyle education. RESULTS: The patients in the PERIO-N group were 1.8 times more likely to be able to consume food orally than the control group (p=0.010). In the PERIO-N group, 50.5% of the patients could orally consume food, 42.6% received a combination of oral and enteral nutrition, and 6.9% only underwent enteral nutrition. In comparison, in the control group, 28.8% of the patients could orally consume food, 53.8% received a combination of oral and enteral nutrition, and 17.3% were only administered enteral nutrition (p=0.004). In addition, patients in the PERIO-N group were discharged at a 1.5 times higher rate than those in the control group (p=0.027). The readmission rate for malnutrition within 3 months was 4% in the PERIO group (5.4% for home discharge only) and 5.8% in the control group (10.5% for home discharge only) (p=0.61). CONCLUSION: This study found that perioperative nutrition education in patients who underwent oesophageal cancer surgery led to increase in the amount of oral intake at discharge. Moreover, the group that received nutrition education did not have an increased probability of hospitalisation due to the risk of malnutrition within 3 months after discharge.	esophagus
