Hepatocellular carcinoma (HCC) has poor prognosis because of its aggressive behavior and limited treatment options, especially in advanced stage. We recently documented that Plexin C1 was overexpressed in HCC. We aimed to evaluate the prognostic significance of Plexin C1 overexpression in HCC in the present study. Methods: Plexin C1 overexpression was evaluated immunohistochemically on paraffin-embedded blocks of the HCC patients. Plexin C1 immunohistochemical staining was scored. Plexin C1 overexpression staining intensity and prevalence were used for plexin scale staining evaluation and plexin scores were estimated according this staining scale. Plexin C1 score and its association with survival and clinicopathological features was assessed. Results: Sixty-seven HCC patients with adequate tissue for pathological evaluation were included. Median age was 63 years with male predominance (male to female ratio was 4.75 (n 57/12). Well-differentiated HCC (53.7%) patients had higher plexin C1 overexpression (p < 0.05). Median OS was 22.1 months. Patients with lower plexin C1 score (< 12) had shorter OS (17.5 vs 30.1 months, p = 0.036). Neutrophil count, GGT, and PNR (platelet/neutrophil ratio) had prognostic significance (p = 0.047, p = 0.018, and p = 0.045). Conclusion: Plexin C1 overexpression is inversely correlated with grade in HCC. The patients with lower rate of Plexin C1 overexpression have worse survival outcome. It might be a prognostic factor in HCC.
