Use of 5α-reductase inhibitors and survival of oesophageal and gastric cancer in a nationwide Swedish cohort study.

Background: We hypothesised that the use of the anti-androgenic drug 5α-reductase inhibitors (5-ARIs) improves survival in patients with oesophago-gastric cancer.

Methods: This nationwide Swedish population-based cohort study included men who underwent surgery for oesophageal or gastric cancer between 2006-2015, with follow-up until the end of 2020. Multivariable Cox regression estimated hazard ratios (HR) for associations between 5-ARIs use and 5-year all-cause mortality (main outcome) and 5-year disease-specific mortality (secondary outcome).

Use of anti-androgenic 5α-reductase inhibitors and risk of oesophageal and gastric cancer by histological type and anatomical sub-site.

Background: To investigate if anti-androgenic medications 5α-reductase inhibitors (5-ARIs) decrease the risk of developing oesophageal and gastric tumours, analysed by histological type and anatomical sub-site.

Methods: A Swedish population-based cohort study between 2005 and 2018 where men using 5-ARIs were considered exposed. For each exposed participant, ten male age-matched non-users of 5-ARIs (non-exposed) were included.

Circulating Levels of Inflammatory and Metabolic Biomarkers and Risk of Esophageal Adenocarcinoma and Barrett Esophagus: Systematic Review and Meta-analysis.

Associations between circulating levels of obesity-related biomarkers and risk of esophageal adenocarcinoma and Barrett esophagus have been reported, but the results are inconsistent. A literature search until October 2018 in MEDLINE and EMBASE was performed. Pooled ORs with 95% confidence intervals (CI) were estimated for associations between 13 obesity-related inflammatory and metabolic biomarkers and risk of esophageal adenocarcinoma or Barrett esophagus using random effect meta-analyses.

Circulating Sex Hormone Levels and Risk of Esophageal Adenocarcinoma in a Prospective Study in Men.

Objectives: Sex hormones have been hypothesized to explain the strong male predominance in esophageal adenocarcinoma, but evidence is needed. This study examined how circulating sex hormone levels influence future risk of esophageal adenocarcinoma.

Methods: This case-control study was nested in a prospective Norwegian cohort (Janus Serum Bank Cohort), including 244 male patients with esophageal adenocarcinoma and 244 male age-matched control participants.

Racial and Ethnic Disparities in the Incidence of Esophageal Cancer in the United States, 1992-2013.

Racial and ethnic disparities in the incidence of esophageal cancer have not been thoroughly characterized with quantitative health-disparity measures. Using data from 1992-2013 from 13 US cancer registries in the Surveillance, Epidemiology, and End Results database, we assessed such disparities according to histological type, based on a variety of disparity metrics. The age-standardized incidence rate of squamous cell carcinoma (SCC) was highest among black persons, while adenocarcinoma mainly affected white men.
