Factors Affecting the Results of Treatment of Patients With Colorectal Cancer

Summary

The study attempts to quantify the relative risks for mortality, anastomotic leakage and other early and late postoperative complications, recurrence rate, cancer-specific survival, recurrence-free survival after colorectal surgery for patients with colorectal cancer depending on the localization of the tumor.

Conditions

• Colorectal Cancer
• Colon Cancer
• Rectal Cancer
• Colorectal Adenocarcinoma
• Colorectal Neoplasms Malignant
• Rectal Adenocarcinoma

Interventions

PROCEDURE

Right hemicolectomy

Resection of the caecum and ascending colon is appropriate for patients with tumors located anywhere from caecum to the transverse colon

PROCEDURE

Left hemicolectomy

Resection of the sigmoid colon is appropriate for patients with tumors located anywhere from the distal transverse colon to the rectosigmoid junction.

PROCEDURE

Sigmoid colon resection

Resection of the sigmoid colon is appropriate for patients with tumors located in the sigmoid colon

PROCEDURE

Anterior resection of the rectum

AR is appropriate for tumors located in rectosigmoid junction and in the proximal rectum

PROCEDURE

Low anterior resection of the rectum

LAR is appropriate for tumors located in the middle and low rectum

PROCEDURE

Abdominoperineal resection

APR is appropriate for distal rectal cancers that invade the external sphincter or the levator muscles

PROCEDURE

Total Colectomy

Total abdominal colectomy may be indicated for patients with primary multiple cancer tumors
