Additional file 3: Figure S2. of Dual role of CD44 isoforms in ampullary adenocarcinoma: CD44s predicts poor prognosis in early cancer and CD44ν is an indicator for recurrence in advanced cancer

Kaplan-Meier analysis of the impact of CD44s expression on overall survival in patients with ampullary adenocarcinoma. (A) Overall survival curve of patients with intestinal type of ampullary adenocarcinoma who underwent surgery by CD44s expression levels (P = 0.4565). (B) Overall survival curve of patients with pancreaticobiliary type of ampullary adenocarcinoma by CD44s expression levels (P = 0.9885). Expression patterns of CD44s were not correlated with overall survival in these two subtypes of ampullary adenocarcinoma. (TIFF 1694 kb)
