  • Title: [Analysis of prognosis-associated factors in pancreatic head and peri-ampullary cancer].
    Author: Roder JD, Siewert JR.
    Journal: Chirurg; 1992 May; 63(5):410-5. PubMed ID: 1376655.
    Abstract:
    Between 1982-1990 we treated 461 patients with adenocarcinoma of the pancreas or the periampullary region. 125 (68 ductal pancreatic and 57 periampullary carcinomas) of these patients (27.1%) underwent resection. Hospital lethality was 3.6% (n = 4). Distribution of pT stages (UICC 1987) and frequency of complete resection (R0 vs. R1/R2) were significantly different between the periampullary and pancreatic tumors. This appeared to be due to the high frequency of pT1/2 periampullary tumors (49.2%) as compared to the prognostically equivalent pT1 tumors of the pancreas (1.9%). The absence of lymph node metastases significantly improved survival of periampullary tumors. This was not observed in tumors of the head of the pancreas. This data indicate that the poor prognosis of ductal pancreatic compared to periampullary cancer is primarily caused by their advanced stage at the time of diagnosis. In addition current resection techniques only inadequately respect the complex lymphatic drainage of the head of the pancreas.
