Multivisceral resections in colorectal cancer

Area of Science:

• Oncology
• Surgical Oncology
• Gastrointestinal Surgery

Background:

• Colorectal cancer (CRC) treatment often involves curative resection.
• Multivisceral organ involvement in CRC necessitates complex surgical approaches.
• Extended radical resection is employed for CRC with adjacent organ invasion.

Purpose of the Study:

• To evaluate outcomes of extended multivisceral radical resection in colorectal cancer patients.
• To assess the impact of tumor infiltration versus inflammatory adherence on survival.
• To determine the effect of surgical technique on postoperative outcomes.

Main Methods:

• Retrospective analysis of 1918 colorectal cancer patients treated between 1969 and 1983.
• Focus on 121 patients undergoing extended multivisceral radical resection.
• Histological confirmation of tumor infiltration vs. inflammatory adherence.

Main Results:

• Postoperative mortality was 12%.
• 57% of patients presented with Dukes' A and B stages.
• Five-year survival rates varied: 54% (inflammatory adherence), 49% (tumor infiltration, no rupture), and 17% (tumor rupture).

Conclusions:

• Extended multivisceral resection for colorectal cancer can achieve significant survival rates.
• Histological findings (infiltration vs. adherence) influence prognosis.
• Avoiding intraoperative tumor rupture is critical for improving patient survival in complex colorectal cancer resections.
