Effect of sex on survival after resection of oesophageal cancer : nationwide cohort study
(2022) In BJS Open 6(3).- Abstract
BACKGROUND: Accumulating evidence suggests a survival benefit after curative oesophageal cancer surgery in women compared with men. The aim of this study was to explore sex disparities in survival after surgery with curative intent in patients with oesophageal cancer.
METHODS: This was a population-based cohort study, including all patients with oesophageal or gastric cancer who underwent surgery with a curative intent between 2006 and 2017 in Sweden. Female versus male mortality rate ratio (MRR) and excess mortality rate ratio (EMRR) were used as measures of survival. Two different parametric models were designed to account for potential confounders. Patients with gastric cancer were used as a comparison group as no differences... (More)
BACKGROUND: Accumulating evidence suggests a survival benefit after curative oesophageal cancer surgery in women compared with men. The aim of this study was to explore sex disparities in survival after surgery with curative intent in patients with oesophageal cancer.
METHODS: This was a population-based cohort study, including all patients with oesophageal or gastric cancer who underwent surgery with a curative intent between 2006 and 2017 in Sweden. Female versus male mortality rate ratio (MRR) and excess mortality rate ratio (EMRR) were used as measures of survival. Two different parametric models were designed to account for potential confounders. Patients with gastric cancer were used as a comparison group as no differences in survival between sexes were expected among these patients.
RESULTS: A total of 1301 patients underwent resection for oesophageal adenocarcinoma and 305 patients for oesophageal squamous cell carcinoma. Women had a lower EMRR (0.76, 95 per cent c.i. 0.58 to 1.01, P = 0.056; 0.52, 95 per cent c.i. 0.32 to 0.84, P = 0.007 respectively) in both histological subtypes. The effect was more profound in early clinical stages, in patients receiving neoadjuvant treatment, and without postoperative complications. No sex-related difference was observed in survival of patients with gastric cancer.
CONCLUSIONS: Women undergoing resection for oesophageal carcinoma have better survival compared with men.
