To investigate the expression of Survivin in patients with extrahepatic cholangiocarcinoma (EHCC) and its relationship with clinicopathological features of EHCC, and the correlation between the expression of Survivin and lymph node micrometastasis, tumor markers, and the prognosis of EHCC. The expression of Survivin protein in paraffin-embedded specimens of 59 patients with EHCC and their 20 para-carcinoma tissues were evaluated by S-P method of immunohistochemical staining. The correlation between the expression of Survivin and the lymph node micrometastasis, clinicopathological features of EHCC and the prognosis of EHCC were analyzed. The positive expression rate of Survivin protein was 67.8% (40/59) in paraffin-embedded specimens of 59 patients with EHCC and was 20.0% (4/20) in para-carcinoma tissues, and difference between carcinoma tissues and para-carcinoma tissues was significant (P<0.01). Histological differentiation in EHCC had a negative correlation with the expression of Survivin protein, while the expression of Survivin protein in EHCC had a positive correlation with TNM of EHCC, lymphatic vessel infiltration, lymph node metastasis and perineural invasion (P<0.05). The serum CA19-9 levels in the positive group with expression of Survivin protein was (290,300+/-55 500) U/L and was obviously higher than that in the negative group [(113,300+/-31,400) U/L, P<0.05]. The mean survival time of the patients with negative expression of Survivin protein was higher than that of the patients with positive expression (43.5 vs. 21.1 months, P<0.01). Screened to significance univariate, the multivariate analysis through Cox proportional hazard model analysis showed that lymph node metastasis, residual tumor margins, and expression of Survivin protein were independent prognosis factors of the patients with EHCC (P<0.05, P<0.01, P<0.01). The expression of Survivin protein in EHCC has a negative correlation with histological differentiation, while has a positive correlation with lymphatic vessel infiltration and serum CA19-9 concentrations. The expression of Survivin protein maybe an independent prognosis factor of the patients with EHCC.
