Adenocarcinoma of the appendix: a clinicopathologic study

Area of Science:

• Gastroenterology
• Oncology
• Surgical Pathology

Background:

• Appendiceal adenocarcinoma is an exceptionally rare gastrointestinal malignancy.
• Understanding its clinicopathologic features and patient outcomes is crucial for effective management.

Purpose of the Study:

• To evaluate the clinicopathologic features and survival rates of patients diagnosed with appendiceal adenocarcinoma.
• To identify common presentations and potential prognostic factors for this rare tumor.

Main Methods:

• Retrospective analysis of 11 patients with histologically confirmed appendiceal adenocarcinoma.
• Review of clinical data, including patient demographics, presenting symptoms, treatment, and survival outcomes.

Main Results:

• The tumor predominantly affected individuals in their fifth decade of life.
• Acute appendicitis was the most frequent clinical presentation (8 out of 11 patients).
• A subset of patients (3 out of 11) presented with distant metastases, suggesting an occult primary appendiceal tumor.

Conclusions:

• Appendiceal adenocarcinoma, though rare, should be considered in the differential diagnosis of appendicitis, especially in middle-aged adults.
• Early detection and diagnosis are critical, as metastatic disease can be an initial presentation.
• Further research is warranted to elucidate optimal treatment strategies and improve survival for appendiceal adenocarcinoma.
