In this study, our aim was to investigate the impact of various prognostic factors on survival in patients with pancreatic carcinoma. The group consisted of 127 cases with adenocarcinoma histologically. The patients had a median age of 58 years, and 81 (64%) were male. The median survival time of the whole group was 7 months, and the 4-year survival rate was 18%. The median survival duration of the patients without metastases was 8 months, and the survival rate at I year was 37.5% and 7.2% at 5 years. It was associated with improved survival compared with the cases with metastatic disease (p < 0.0001). In univariate analysis, decreased performance status (p = 0.0009) and unresectability of tumor (p < 0.0001) were associated with poor outcome. However, only surgery was found to be a statistically significant parameter in multivariate analysis (P = 0.002). The median survival duration of patients with metastases was 5 months, and the 1-year survival rate was 10%. Age younger than 60 years (p = 0.04), decreased serum hemoglobin levels (p 0.04), and elevated lactic dehydrogenase (LDH) levels (p 0.0001) were associated with a significantly shorter survival rate. In the Cox model, a high serum LDH level was the only independent unfavorable prognostic factor (p = 0.001). In conclusion, surgical intervention in the group without metastases and serum LDH levels in the group with metastases were the most important prognostic factors influencing survival. Pretreatment serum LDH determinations may provide a useful means of stratifying patient populations when comparing treatment programs for advanced pancreatic cancer.
