Study of Factors Influencing Treatment Outcomes in Patients Undergoing Surgery for Colorectal Cancer

What this Trial Is About

Researchers are examining how the location of colorectal cancer tumors affects outcomes after surgery. This study looks at risks such as death, leakage at the surgical connection, early and late complications, cancer recurrence, and survival rates specific to cancer over several years after surgery. The study focuses on patients with colorectal cancer undergoing surgery and aims to understand how tumor location impacts treatment results. Participants receive different types of surgical procedures depending on where their tumor is located. These include removal of parts of the colon or rectum, such as right or left hemicolectomy, sigmoid colon resection, anterior or low anterior resection of the rectum, abdominoperineal resection, or total colectomy for multiple tumors. Each surgery is selected based on the tumors position from the cecum to the rectum or if multiple primary tumors are present. Throughout the study, researchers will monitor participants for surgical complications within 30 days, leakage rates at the surgical join after 3 months, and mortality along with cancer recurrence and survival up to 3 years post-surgery. Patients will attend study visits to provide data for these outcomes, including cancer-specific and recurrence-free survival. The study is observational and follows patients over this period to collect detailed safety and effectiveness information about colorectal cancer surgeries.
