[Surgical palliation of pancreatic carcinoma. Results of a 7 year period].

INTRODUCTION

High perioperative complication rates in the 1980s led to preferred use of endoscopic therapy for surgical palliation of pancreatic cancer. This encouraged us to analyse our own patients retrospectively.

MATERIAL AND METHODS

In the period from 1 January 1992 to 31 December 1998, 253 patients with an exocrine carcinoma of the pancreas were operated on at the St. Elisabeth Hospital Cologne-Hohenlind: 73 patients (28.9%) underwent curative resection (R0) while 180 patients (71.1%) had palliative operative treatment (R1/R2). Palliative resection was performed in 22 patients (8.7%). Intestinal bypass surgery was done in 113 patients (44.7%) as a gastrojejunostomy and in 16 patients (6.3%) as a duodenojejunostomy. A biliodigestive anastomosis was performed in 85 patients (33.6%). This procedure was combined with a gastroenterostomy in 78 patients (30.8%). In 18 patients (7.1%) no surgical palliation was possible and the operation finished as a diagnostic laparotomy.

RESULTS

The overall mortality rate within the first 30 (60) days was 5.5% (12.7%). Patients whose carcinoma had been resected curatively had a 30 (60)-day mortality rate of 2.7% (4.1%), compared to a rate in palliatively treated patients (resection/bypass/probatoria) of 6.7% (16.1%). Patients with palliatively resected tumor had perioperative mortality of 4.5% (4.5%), whereas patients who did not undergo resection had 6.9% (17.7%). The survival rate for curatively resected patients after Kaplan-Meier extrapolation was 64.7% after 1 year and 31.2% and 26.2% after 3 and 5 years, with a median survival time of 552 days. Palliatively operated patients had a survival rate of 19.4%, 2.5% and 0% for 1, 3 and 5 years. Median survival time was 171 days in this situation. Compared to patients without resection (17.4% and 2.0%), patients with palliative resection had survival rates for 1 and 3 years of 40% und 5.9%. After 5 years none of these patients were alive.

CONCLUSIONS

Our data show a high success of surgical palliation in pancreatic cancer in centers with a high frequency of pancreatic surgery. Patients that could not be cured (R1/R2), although undergoing extensive procedures, had better survival rates than patients treated with bypass surgery. Perioperative mortality rate was comparatively low. This justifies aggressive surgical management of pancreatic carcinoma.
