Prognostic significance of the cachexia index for patients with perihilar cholangiocarcinoma

The prognostic value of the preoperative cachexia index for patients with perihilar cholangiocarcinoma remains unclear. We retrospectively evaluated 236 patients who underwent radical resection for perihilar cholangiocarcinoma from September 2002 to December 2020. The cachexia index was calculated a...

Shrnutí:The prognostic value of the preoperative cachexia index for patients with perihilar cholangiocarcinoma remains unclear. We retrospectively evaluated 236 patients who underwent radical resection for perihilar cholangiocarcinoma from September 2002 to December 2020. The cachexia index was calculated as follows: (skeletal muscle index × albumin level)/neutrophil-to-lymphocyte ratio, with sex-specific cutoff values determined via receiver operating characteristic curves on the basis of 3-year survival data. Clinicopathologic characteristics and survival outcomes were compared between the low-cachexia index (n = 95) and high-cachexia index (n = 141) groups. Multivariable analyses were performed to identify prognostic factors for overall survival and relapse-free survival. The low-cachexia index group was characterized by greater carbohydrate antigen 19–9 level (56 vs 31 U/mL, P = .024) and greater proportion of preoperative biliary drainage (84% vs 70%, P = .013). The low-cachexia index group underwent vascular resection and reconstruction more frequently (47% vs 29%, P = .006) and had a greater rate of lymph node metastasis (54% vs 35%, P = .005). The median overall survival and relapse-free survival times of the low-cachexia index group were significantly worse than those of the high-cachexia index group (overall survival, 29.0 vs 47.4 months, P < .001; relapse-free survival, 17.2 vs 33.1 months, P < .001). Multivariable analysis revealed that a preoperative cachexia index (hazard ratio for overall survival, 0.95, P = .008; hazard ratio for relapse-free survival, 0.95, P = .017) and high preoperative carbohydrate antigen 19-9 level (hazard ratio for overall survival, 1.01, P = .002; hazard ratio for relapse-free survival, 1.01, P = .012) were prognostic factors. The cachexia index may be a useful biomarker for the prediction of tumor aggressiveness and prognosis before perihilar cholangiocarcinoma resection. [Display omitted]
