Summary
Laparoscopic surgery for rectal cancer shows promising oncologic outcomes and comparable quality of life to open surgery. Further research is needed to define its role and patient selection for this minimally invasive approach.
Area of Science:
- Oncology
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Laparoscopic surgery for rectal cancer remains controversial, with key concerns including oncologic resection adequacy, recurrence rates, survival, and quality of life.
- Non-randomized studies suggest laparoscopic approaches can achieve comparable margins and lymph node harvest to open surgery.
Purpose of the Study:
- To evaluate the long-term oncologic and functional outcomes of laparoscopic surgery for rectal cancer.
- To compare functional results with conventional open surgery using a matched-pair analysis.
Main Methods:
- Retrospective analysis of 52 patients undergoing laparoscopic rectal cancer surgery with curative intent.
- Matched-pair analysis comparing laparoscopic and open surgery based on sex, age, resection type, surgery period, and disease stage (UICC).
- Functional outcomes (bladder and sexual dysfunction) assessed using the EORTC QLQ CR38 score.
Main Results:
- Median follow-up of 48 months; 3-year survival rate of 93%, 5-year survival rate of 62%.
- Local recurrence rate of 1.9%, distant metastasis in 11.5%, with no port-site metastasis.
- No statistically significant difference in bladder or sexual dysfunction between laparoscopic and open surgery groups.
Conclusions:
- Laparoscopic surgery for rectal cancer can achieve comparable oncologic results and quality of life to open surgery in selected patients.
- Further extensive studies are required to establish the definitive role of laparoscopic techniques, optimize patient selection, and explore combination therapies.
