Prognosis Factors in Carcinoma of the Head of the Pancreas

BACKGROUND: Due to a low survival rate even after a R0 resection of cancer of the head of the pancreas, a strict indication for a pancreaticoduodenectomy seems to be sensible. We have therefore analyzed our patients for possible prognosis factors. METHODS: In a retrospective trial the courses of disease of all patients (1981-1996) with resected histologically proven carcinoma of the head of the pancreas were analyzed. The following patient-specific parameters were evaluated and examined in a single or multivariate analysis of prognosis factors: age, gender, tumor size (T status), lymph node involvement (N status), dimension of resection, operation method, time of operation, morbidity, clinic lethality and survival rate. RESULTS: Between 1981 and 1996, 500 patients with ductal adenocarcinoma of the head of the pancreas were treated surgically. The rate of resection increased from 32.1% (1981-1986) to 37.8% (1991-1996) whereas the mortality rate decreased from 13.3 to 7.3%. The 5-year survival rate after resection was 11.8% with a median survival time of 13.8 months. In a multivariate analysis, only small tumors (T1, p < 0.016), the R0 status (p < 0.017) and the resection had a significant influence on the survival rate. CONCLUSION: Prognosis factors in the treatment of pancreatic cancer were tumor size (T1), tumor resection and R0 status.
