Brief 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.

Outcome Measures
Primary Outcomes (2)
Anastomotic leakage rate
Anastomotic leakage rate after colorectal resection. AL is confirmed by one or more of the following conditions: * fecal discharge from the pelvic drainage at any time after surgery * rectovaginal fistula defined as fecal or mucus discharge from the vagina * pelvic sepsis as defined by the collection of pus/ fecal material in the pelvis documented by CT scan * contrast present outside of the anastomosis as seen by X-Ray contrast enema proctography or CT contrast enema proctography
3 months after surgery
Mortality rate
the overall mortality after colorectal cancer surgery
3 years after surgery
Secondary Outcomes (4)
30-day complication rate
30 days after surgery
Recurrence rate
3 years after surgery
Cancer-specific survival
3 years after surgery
Recurrence-free survival
3 years after surgery
Study Arms (4)
Patients with right-sided colon cancer
Tumors located anywhere from the cecum to the proximal transverse colon.
Patients with left-sided colon cancer
Tumors located anywhere from the distal transverse colon to the rectosigmoid junction
Patients with rectal cancer
Tumors located in rectosigmoid junction and in the rectum with/without the external sphincter or the levator muscles invasion
Patients with right- and left-sided colon cancer (primary multiple cancer)
Patients with primary multiple cancer tumors
Interventions
Resection of the caecum and ascending colon is appropriate for patients with tumors located anywhere from caecum to the transverse colon
Resection of the sigmoid colon is appropriate for patients with tumors located anywhere from the distal transverse colon to the rectosigmoid junction.
Resection of the sigmoid colon is appropriate for patients with tumors located in the sigmoid colon
AR is appropriate for tumors located in rectosigmoid junction and in the proximal rectum
LAR is appropriate for tumors located in the middle and low rectum
APR is appropriate for distal rectal cancers that invade the external sphincter or the levator muscles
Total abdominal colectomy may be indicated for patients with primary multiple cancer tumors
Eligibility Criteria

You may qualify if:
- Histologically proven primary adenocarcinoma of bowel;
- All patients who have indications for surgical treatment of colorectal cancer based on the decision of the oncological council;
- Signed informed consent with agreement to attend all study visits;
You may not qualify if:
