Locally Advanced or Metastatic Pancreatic Adenocarcinoma: Easily Available Factors of Predictive Prolonged Survival Under Gemcitabine.

BACKGROUND: Prognosis of patients with locally advanced or metastatic pancreatic adenocarcinoma is poor. In this study, we assessed the predictive value of easily available baseline factors for prolonged survival.

PATIENTS AND METHODS: We conducted a retrospective study on patients who received gemcitabine between 1999 and 2010 for locally advanced or metastatic pancreatic adenocarcinoma. The primary end-point was the 12-month survival rate.

RESULTS: We included 195 patients. The median age was 62.9 years; the performance status was 0-1 in 80 and 2-3 in 92 patients. The median number of metastatic sites was one. A total of 73 patients (37.4%) were alive 12 months after beginning chemotherapy. In multivariate analysis, no liver metastasis, CA19-9 level <250 IU/ml and localized or locally advanced cancer at diagnosis were good prognostic factors. According to a clinical score based on these features, overall survival was 7.7, 13.5, 19.7 and 21.0 months, respectively (p<0.001).

CONCLUSION: We identified easily available prognostic factors for prolonged survival in patients treated with gemcitabine.
