[Surgical Therapy and Prognostic Factors for Carcinoma of Vater's Papilla].

BACKGROUND

Carcinoma of ampulla of Vater are rare tumours of the GI-tract with an improved prognosis compared to other periampullary tumours. Analysis of survival and prognostic factors are limited due to the low incidence of the carcinoma. The intention of this study in patients with papillary carcinoma was to evaluate short- and long-term survival and to identify prognostic factors for pancreatectomy and reconstruction using pancreatogastrostomy as treatment of carcinoma of Vater's ampulla.

PATIENTS AND METHODS

Between 1989 and 2008 76 patients with a carcinoma of the ampulla of Vater were treated by oncological resection followed by pancreatogastrostomy. Various factors such as demographics, perioperative factors, histopathological findings as well as short- and long-term survival were evaluated retrospectively. Data were analysed statistically using Kaplan-Meier estimates of survival with log-rank test and uni- and multivariate analysis with Cox regression.

RESULTS

The overall 5-year survival was 46 %, the 10-year survival 26 % for resected patients. By univariate analysis we could demonstrate that lymph node metastasis is the only predictor for outcome. In the multivariate analysis, age, sex, grading and especially lymph node status were a significant predictor for the survival of patients.

CONCLUSION

In the current patient cohort lymph node status was the most important independent predictor of outcome after resection of carcinoma of Vater's papilla.
