Stage- and age-adjusted cost-effectiveness analysis of laparoscopic surgery in rectal cancer.

Background: It has been argued that laparoscopy should be a standard treatment in rectal cancer due to its greater technical complexity. The objective of this study was to conduct a cost-effectiveness analysis to compare laparoscopy with open surgery for rectal cancer adjusting for age and clinical stage.

Methods: A real-world prospective cost-effectiveness cohort study was conducted with data on costs and effectiveness at individual patient level.

Combining statistical techniques to predict postsurgical risk of 1-year mortality for patients with colon cancer.

Introduction: Colorectal cancer is one of the most frequently diagnosed malignancies and a common cause of cancer-related mortality. The aim of this study was to develop and validate a clinical predictive model for 1-year mortality among patients with colon cancer who survive for at least 30 days after surgery.

Methods: Patients diagnosed with colon cancer who had surgery for the first time and who survived 30 days after the surgery were selected prospectively.
