Background: Late effects of chemotherapy could affect mortality amongst cancer survivors. This study aimed to clarify if neoadjuvant chemotherapy for gastric adenocarcinoma influences the long-term survival in individuals cured of this tumour.
Methods: This was a nationwide and population-based cohort study that included all individuals who underwent gastrectomy for gastric adenocarcinoma in Sweden between 2006 and 2015 and survived for ≥ 5 years after surgery.
Background: It is unknown if gastric adenocarcinoma survivors have longer, shorter, or similar survival compared to the background population. This knowledge could contribute to evidence-based monitoring strategies, healthcare recommendations, and information for patients and families.
Methods: This population-based cohort study included all patients who underwent gastrectomy for gastric adenocarcinoma between 2006-2015 in Sweden and survived ≥ 5 years after surgery.
Background: Increasing surgeon age may influence patient outcomes after complex procedures due to gained experience but also decreased technical and cognitive abilities. This study aimed to clarify whether surgeon age influences patients' long-term survival after gastrectomy for gastric adenocarcinoma.
Methods: Population-based cohort study including all patients who underwent open and curatively intended gastrectomy for gastric adenocarcinoma between 2006 and 2015 in Sweden, with follow-up throughout 2020.
Background: Studies have suggested that medication with statins improves survival in patients with gastric cancer, but methodological issues have limited the interpretability and prohibited conclusive results. We aimed to provide valid evidence as to whether statin use improves survival of gastric adenocarcinoma.
Methods: This nationwide and population-based cohort study included virtually all patients who underwent curatively intended surgery (gastrectomy) for gastric adenocarcinoma in Sweden between 2006 and 2015 with follow-up throughout 2019 for disease-specific mortality and 2020 for all-cause mortality.
Background: Cancer surgery conducted late during the working week might decrease long-term survival for some tumours. Studies on how weekday of gastrectomy influences long-term survival following gastric cancer are few and show conflicting results, which prompted the present investigation.
Methods: This population-based cohort study included almost all patients who underwent gastrectomy for gastric adenocarcinoma in Sweden between 2006 and 2015, with follow-up throughout 2020.
Background: Low-dose aspirin use may reduce cancer incidence and mortality, but its influence on gastric adenocarcinoma survival is unclear. This study aimed to assess whether aspirin use improves long-term survival following gastrectomy for gastric adenocarcinoma.
Methods: This population-based cohort study included almost all patients who underwent gastrectomy for gastric adenocarcinoma in Sweden from 2006 to 2015, with follow-up throughout 2020.
Background: Most studies examining prognostic factors after gastrectomy come from selected patients and non-Western populations. This nationwide population-based cohort study aims to identify prognostic factors after surgery for gastric adenocarcinoma in an unselected Western cohort.
Methods: This study included 98% of patients who underwent gastrectomy for gastric adenocarcinoma in Sweden in 2006-2015, with follow-up through 2019.
