Obstructive colonic cancer

A R Gennaro, R R Tyson

    Diseases of the Colon and Rectum
    |July 1, 1978
    PubMed
    Summary
    This summary is machine-generated.

    For obstructive colonic cancers, staged procedures are best for left-sided tumors, while primary resection suits proximal cases. Survival rates after surgery for these cancers remain low, with only six patients surviving five years in this study.

    Area of Science:

    • Colorectal surgery
    • Surgical oncology
    • Gastrointestinal oncology

    Background:

    • Colonic cancers causing obstruction present significant clinical challenges.
    • Treatment strategies for obstructive colonic cancer require careful consideration of tumor location.
    • Evaluating outcomes is crucial for improving patient management.

    Purpose of the Study:

    • To review the clinical courses of patients with obstructive colonic cancers.
    • To assess the effectiveness of different surgical approaches.
    • To determine the survival rates associated with various treatments.

    Main Methods:

    • Retrospective review of clinical data for 68 patients.
    • Analysis of treatment strategies based on tumor location (proximal vs. left colon).

  • Evaluation of operative mortality and long-term survival (five-year follow-up).

    • Main Results:

    • A staged surgical procedure was most appropriate for the majority of acutely obstructing left colon cancers.
    • Primary resection was deemed suitable for more proximal colonic cancers with obstruction.
    • The overall mortality rate, including nonoperative deaths, was 16.2%.
    • Only six patients (approximately 8.8%) achieved five-year survival.

    Conclusions:

    • Treatment decisions for obstructive colonic cancer should be guided by tumor location.
    • Conventional staged procedures and primary resection remain key surgical options.
    • The prognosis for patients with obstructive colonic cancer is poor, with limited long-term survival rates.
