Histopathologic prognostic factors for ductal carcinoma of the head of the pancreas

Oncol Rep. 1994 Jan;1(1):145-8. doi: 10.3892/or.1.1.145.


To establish useful prognostic factors for carcinoma of the head of the pancreas a retrospective analysis of histopathologic factors was performed for 44 patients treated with resection. Overall survival rates after 1, 2, 3 and 5 years were 63.6%, 34.5%, 26.9% and 23.9%, respectively. Eight patients lived for 5 years. The significant factors affecting survival were nodal involvement (n), retroperitoneal invasion (rp), and the degree of cancer cell invasion to the exposed cut surface (ew). Tumor size (t), serosal invasion (s) and histologic type did not influence survival by univariate analysis. According to the Cox multiregression analysis, nodal involvement is the only useful prognostic factor. Lymph node metastasis is the most important prognostic factor. To improve the prognosis of pancreatic cancer it is necessary to perform extended lymph node dissection.
