| Abstract: | Objective: The purpose of this study was to evaluate the regional pancreatectomy as surgical therapy for ductal adenocarcinoma of the pancreas and to evaluate potential prognostic factors. Summary Background Data: Regional pancreatectomy was developed as a more adequate surgical procedure for pancreatic cancer in an attempt to improve the cure rate for this highly lethal disease. Few studies have evaluated large numbers of patients treated with this technique, and in recent years the emphasis has been on more limited surgery for pancreatic cancer. Methods: Fifty six patients with ductal adenocarcinoma of the pancreatic head were treated by regional subtotal or total pancreatectomy. Clinical and pathologic parameters were reviewed and potential prognostic factors were compared statistically. The three patients who died within 30 days of the operation were excluded from the survival analysis. Results: Primary tumor size was the strongest determinant of prognosis. The mean tumor size was 3.9 cm (range, 1-7 cm). Eighty-five percent of patients had peripancreatic soft tissue invasion microscopically, and 58% had regional lymph node metastasis, Kaplan-Meier survival curves indicated a 33% 5-year survival for patients with tumor 2.5 cm or less in diameter (n = 12) and 12% for patients with larger tumors (n = 39). No patient with a tumor larger than 5 cm survived more than 5 years. Mean tumor size was not significantly associated with lymph node metastases, but 5 of 12 patients (42%) with primary tumor ≤2.5 cm had lymph node metastases. Twenty-four percent of patients with negative lymph nodes and 14% with positive lymph nodes survived 5 years. The difference was not statistically significant (p = 0.3), but this is likely related to sample size. The 30-day operative modality was 53%. The most common complications were infection, gastrointestinal bleeding, and gastric stasis. Conclusions: After regional pancreatectomy, tumor size is the strongest predictor of prognosis. A multiinstitutional randomized prospective trial of regional pancreatectomy versus pancreaticoduodenectomy is warranted in previously untreated, noninfected cases. |
