Synchronous colorectal cancers occur in 4.8% of patients, often in older individuals. Management decisions for multiple colorectal cancers depend on tumor location and polyp association.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Colorectal Surgery

Context:

  • Synchronous colorectal cancers (SCCs) present a diagnostic and therapeutic challenge.
  • Previous studies report SCC incidence varying from 1.7% to 9.3%.
  • Diagnostic criteria for SCCs have been inconsistent, impacting reported frequencies.

Purpose:

  • To determine the frequency and location of SCCs.
  • To analyze therapeutic choices for SCCs.
  • To evaluate the association of adenomatous polyps with SCCs.

Summary:

  • A retrospective study analyzed 249 colorectal cancer surgeries between 1980 and 1990.
  • Twelve patients (4.8%) had synchronous colorectal cancers, all diagnosed simultaneously.
  • Patients with SCCs were older (average 68.8 years) than those with single cancers (63.3 years).

  • Two-thirds of SCCs were in the sigmoid or colon; one-third involved non-adjacent segments.
  • Half of the SCC patients had associated adenomatous polyps, prompting discussion on colectomy extent.

    • Impact:

    • Findings highlight the need for careful consideration of colectomy extent in SCC management.
    • The frequent association with polyps suggests a potential role for subtotal or total colectomy.
    • Segmental colectomy may be appropriate when cancers are confined to one segment or polyps are localized.
