RESUMO

Objective:This study aims to determine the efficacy of chemotherapy and to identify potential chemotherapy agents for advanced primary duodenal carcinoma (PDC). Methods:Fifty-six patients with advanced PDC, who did and did not receive chemo-therapy, were involved in this study. Response rates (RR), disease control rates (DCR), progression-free survival (PFS), and overall sur-vival (OS) were analyzed. Results:The overall RR and DCR of 43 patients were 19.04%and 71.42%, respectively. The patients who re-ceived chemotherapy agents fluorourzcil and oxaliplatin exhibited higher RR compared with patients who received other chemotherapy combinations (35.29%vs. 7.69%, P=0.010 9). Palliative chemotherapy improved the OS of patients with advanced PDC compared with patients who did not receive chemotherapy (13.35 months vs. 5.65 months, HR=0.203, 95%CI:0.083 to 0.497, P=0.000 5). Compared with the use of other chemotherapy regimens, treatment with a fluorourzcil-based chemotherapy agent resulted in a longer PFS (5.08 months vs. 1.08 months, HR=0.004, 95%CI:0.000 to 0.315, P=0.013 2). Multivariate analysis indicated mucinous histology and lymph mode metastasis as factors predictive of poor prognosis in patients with advanced PDC. Conclusion:Palliative chemotherapy may im-prove the OS of patients with advanced PDC.

RESUMO

The Peutz-Jeghers syndrome is an autosomal dominant disease characterized by hamartomatous polyps in the gastrointestinal tract and mucocutaneous melanin pigmentation. Although these polyps are believed to have little potential for malignancy, and the disease was believed to have a relatively benign course, it recently has been recognized that patients with this syndrome are at increased risk for the development of cancer at gastrointestinal and nongastrointestinal sites. A 33-year-old male patient was admitted because of vomiting and abdominal pain for 3 months duration. A diagnosis of Peutz-Jeghers syndrome was made 3 years ago by multiple hamartomatous polyps confined to the colon and mucocutaneous pigmentation. A barium study showed abrupt string like luminal narrowing at the 4th portion of the duodenum. On laparotomy, there was an annular constricting mass involving the serosa of duodenum with multiple metastasis to liver, so a segmental resection of small bowel followed by chemotherapy was performed. The histologic finding was adenocarcinoma.
