Summary
Primary duodenal carcinoma, a rare cancer, is often diagnosed late due to vague symptoms. Increased awareness and aggressive diagnostics are crucial for improving cure rates in these uncommon duodenal tumors.
Area of Science:
- Gastroenterology
- Surgical Oncology
Background:
- Primary duodenal carcinoma is an infrequent malignancy.
- Diagnosis is often delayed due to nonspecific symptoms mimicking benign conditions.
Observation:
- A retrospective review of five patients with duodenal adenocarcinoma (excluding periampullary tumors) treated between 1973 and 1983.
- Common symptoms included nausea, vomiting, and microcytic anemia, with positive stool tests in some.
- Upper gastrointestinal series suggested carcinoma in all cases; however, endoscopy and biopsy had limited diagnostic yield.
Findings:
- Lesions were located in the third and fourth portions of the duodenum in four patients.
- Only two of five patients had resectable disease at laparotomy, with one undergoing segmental resection.
- Three patients presented with unresectable disease due to metastatic spread or local invasion.
Implications:
- Delayed diagnosis of duodenal carcinoma significantly impacts resectability and prognosis.
- Enhanced clinical suspicion and aggressive diagnostic work-up are essential for earlier detection.
- Improving diagnostic strategies may lead to a higher percentage of successful treatments and cures for duodenal adenocarcinoma.
