Summary
Laparoscopic surgery is feasible for T4 colorectal cancer resection, challenging its status as a contraindication. This minimally invasive approach shows promising operative and oncologic outcomes for advanced cases.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
- Colorectal Cancer Research
Background:
- T4 colorectal cancer traditionally contraindicates laparoscopy due to concerns of incomplete resection and high conversion rates.
- Limited data exists on the feasibility and outcomes of laparoscopic approaches for advanced T4 colorectal cancer.
Purpose of the Study:
- To assess the feasibility of laparoscopic resection for T4 colorectal cancer.
- To evaluate the operative and oncologic outcomes of this minimally invasive approach.
Main Methods:
- A cohort of 39 patients with T4 colorectal cancer (diagnosed via imaging) underwent laparoscopic resection between 2006 and 2009.
- Cancers involved various sites including colon, rectum, and adjacent organs (e.g., pelvic sidewall, bladder, small bowel).
Main Results:
- The overall conversion rate to open surgery was 18%, with postoperative mortality and morbidity at 2.5% and 33%, respectively.
- Pathological T4 invasion was confirmed in 77% of patients, with an R1 resection rate of 13%.
- Median follow-up of 19 months showed high overall survival (97%) and disease-free survival (89%) rates.
Conclusions:
- Laparoscopic resection is a feasible option for T4 colorectal cancer.
- Laparoscopy should not be considered an absolute contraindication for advanced colorectal cancer.
