Summary
Extended resection for colorectal cancer with adjacent structure infiltration lowers survival. Radical surgery is vital for primary tumors involving the urogenital tract, but palliative care is preferred for recurrent tumors to improve quality of life.
Area of Science:
- Oncology
- Surgical Oncology
- Gastroenterology
Background:
- Colorectal cancer (CRC) infiltration of adjacent structures, particularly the urogenital tract, presents complex surgical challenges.
- Dukes' staging is crucial for CRC prognosis, but outcomes for tumors with local invasion require further elucidation.
Purpose of the Study:
- To evaluate the survival outcomes of patients with rectosigmoid cancer involving the urogenital tract based on tumor type (primary vs. recurrent) and surgical approach (radical vs. palliative).
- To determine the optimal surgical strategy for rectosigmoid cancers with urogenital tract involvement.
Main Methods:
- Retrospective analysis of 71 patients with rectosigmoid cancer involving the urogenital tract.
- Comparison of survival rates between radical and palliative surgical procedures for primary and recurrent tumors.
Main Results:
- Patients with Dukes' B or C colorectal cancer undergoing extended resection due to infiltration had significantly lower survival rates.
- For primary rectosigmoid tumors involving the urogenital tract, radical surgery yielded a mean survival of 60.7 months, compared to 28.2 months for palliative procedures.
- No significant survival difference was observed between radical (17.6 months) and palliative (14.1 months) surgery for recurrent rectosigmoid tumors.
Conclusions:
- Radical surgical intervention is mandatory for primary rectosigmoid carcinoma involving the urogenital tract to maximize survival.
- For recurrent rectosigmoid tumors with urogenital tract involvement, aggressive surgery is questionable, with palliative approaches prioritizing quality of life being preferable.
