Summary
Adenocarcinoma of the appendix remains difficult to diagnose preoperatively. Despite review of cases, there has been no improvement in diagnosis or prognosis for this rare appendiceal tumor.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Review of appendiceal adenocarcinoma cases from Hamilton, Ontario (1974-1980).
- Comparison with a previous Hamilton-based report on the same condition.
Observation:
- Seven patients (5 male, 2 female) with a mean age of 55.6 years.
- Unusual presenting signs and symptoms, leading to infrequent preoperative diagnosis.
- Histologic examination is crucial for identifying epithelial types and guiding treatment.
Findings:
- No improvement in preoperative diagnostic accuracy compared to earlier reports.
- Prognosis remains unchanged, highlighting diagnostic challenges.
- Appendiceal tumors often mimic cecal or ileal malignancies.
Implications:
- Consider appendiceal adenocarcinoma in non-inflammatory appendiceal masses.
- Recommend frequent use of frozen-section examination for diagnosis confirmation.
- Standard therapy remains radical right hemicolectomy, though appendectomy may suffice for early-stage tumors.
