RESUMO
<p><b>OBJECTIVE</b>To investigate the factors influencing the long-term survival of pancreatic carcinoma patients after radical resection.</p><p><b>METHODS</b>The data of 184 pancreatic carcinoma patients with radical resection were analyzed retrospectively. Analysis of the prognostic factors influencing the long-term survival was performed using Cox proportional hazard regression model.</p><p><b>RESULTS</b>The overall 1-, 3- and 5-year survival rates in this group were 61.7%, 29.0% and 14.3%, respectively. They were 78.0%, 38.4% and 25.7%, respectively, for the patients with a tumor < 3 cm in diameter, significantly better than those with a tumor >or= 3 cm (52.8%, 22.7% and 7.2%, respectively, P < 0.05). Moreover, the 1-, 3- and 5-year survival rates were 67.6%, 30.5% and 17.4%, respectively, in the patients without lymph node involvement, much longer than that in those with lymph node metastasis (37.1%, 20.6% and 0, respectively, P < 0.05). Multivariate analysis by Cox proportional hazard regression model revealed that the tumor size (P < 0.05) and lymph node metastasis (P < 0.01) significantly influenced the long-term survival of the patients.</p><p><b>CONCLUSION</b>Tumor size and lymph node metastasis are significant factors influencing the long-term survival of pancreatic carcinoma patients with radical resection. Therefore, early diagnosis and radical resection are the key points to improve treatment outcome.</p>
