Abstract
BACKGROUND: Perihilar cholangiocarcinoma has one of the poorest prognoses of all cancers. However, mortality and morbidity rates after surgical resection are 0-15% and 14-66%, respectively. Additionally, the 5-year overall survival rates are reported at 22-40%. These findings indicate that only selected patients achieve satisfactory beneficial effects from operative treatment. This retrospective study sought to investigate preoperatively available prognostic factors and establish a new preoperative staging system to predict survival after major hepatectomy of perihilar cholangiocarcinoma. PATIENTS AND METHODS: We evaluated 121 consecutive patients who underwent operative exploration for perihilar cholangiocarcinoma. RESULTS: Univariate and multivariate analysis using the identified preoperative factors revealed that 4 factors (platelet-lymphocyte ratio [PLR] > 150, serum C-reactive protein [CRP] levels > 0.5 mg/dL, albumin levels < 3.5 g/dL, and carcinoembryonic antigen [CEA] levels > 7.0 ng/mL) were independent prognostic factors of postoperative survival. These 4 preoperative factors were allocated 1 point each. The total score was defined as the Preoperative Prognostic Score (PPS). Patients with a PPS of 0, 1, 2, or 3/4 had a 5-year survival of 84.3%, 51.3%, 46.4%, and 0%, respectively. There were also differences in the 5-year survival according to the PPS (0 vs 1 [P = .013] and 2 vs 3/4 [P < .001]). Patients with a total PPS of 3/4 had a dismal prognosis, with a median survival of 11.3 months. CONCLUSION: A new preoperative scoring system using PLR, serum CRP, albumin, and CEA levels could predict postoperative survival resection of perihilar cholangiocarcinoma.
