Primary duodenal cancer is a rare disease that accounts for 0.8-2% of all gastrointestinal malignancies. Surgical resection is only the curative treatment, but optimal treatment opinion has not been established. We have experienced seven patients with primary advanced duodenal carcinoma so far, and successfully performed radical pancreatoduodenectomy for them. All tumors were at the second portion of the duodenum, and large over 50mm in maximum diameter. Tumors were resected safely in all patients, no local recurrences occurred after the operation. Pancreas invasion was seen in six patients, and lymph node metastasis was detected in three patients, however, the 5-year survival rate (66.7%) was excellent compared to prognoses of other periampullary tumors. Consequently, we should make an attempt to perform surgical treatment for primary duodenal cancer, if pancreas invasion or lymph node metastasis is suspected in preoperative examination.
