Abstract

Background: High subcutaneous adipose tissue radiodensity (SATr), an indirect surrogate marker of adipose tissue quality, was associated with poor prognosis in various cancers. The present study aimed to assess the association of SATr with survival outcomes in patients with advanced biliary tract cancer (BTC).

Methods: This retrospective, single-center study included patients with unresectable or recurrent BTC who underwent chemotherapy/chemoradiotherapy. Overall survival (OS) and progression-free survival (PFS) were assessed using the log-rank test and the Cox proportional hazards model according to the SATr status.

Results: The study cohort included 234 patients, including 38 and 196 patients with high and non-high SATr, respectively. The median OS durations were 10.5 and 17.4 months (HR = 1.72, 95% CI: 1.19-2.49, p < .01) and the median PFS durations were 4.9 and 8.0 months (HR = 1.52, 95% CI: 1.05-2.20, p = .03) in patients with high and non-high SATr, respectively. By multivariate analysis, high SATr, neutrophil/lymphocyte ratio >5, modified Glasgow prognostic score 1-2, and serum carcinoembryonic antigen >5.0 ng/mL were predictors for OS (HR, 1.66, 2.42, 2.00, and 1.56, respectively; p < .05). By multivariate analysis, metastatic disease status, high SATr, neutrophil/lymphocyte ratio >5, and modified Glasgow prognostic score 1-2 were independent risk factors for worse PFS (HR, 1.56, 1.56, 1.81, and 1.57, respectively; p < .05).

Conclusions: High SATr was associated with risk of tumor progression and poor prognosis in patients with advanced BTC treated by palliative chemotherapy/chemoradiotherapy.

皮下脂肪组织放射密度作为晚期胆道癌预后不良的预测因子。

背景：高皮下脂肪组织放射密度（SATr）是脂肪组织质量的间接替代标志物，与各种癌症的不良预后相关。本研究旨在评估SATr与晚期胆道癌（BTC）患者生存结局的关系。方法：这项回顾性、单中心研究纳入了接受化疗/放化疗的不可切除或复发性BTC患者。根据SATr状态，采用log-rank检验和Cox比例风险模型评估总生存期（OS）和无进展生存期（PFS）。结果：研究队列纳入234例患者，其中高、非高SATr患者分别为38例和196例。中位OS持续时间分别为10.5和17.4个月（HR = 1.72, 95% CI: 1.19-2.49, p 5），改良格拉斯哥预后评分1-2和血清癌胚抗原>5.0 ng/mL是OS的预测因子(HR分别为1.66、2.42、2.00和1.56；p 5和改良格拉斯哥预后评分1-2是PFS恶化的独立危险因素(HR分别为1.56、1.56、1.81和1.57；结论：姑息性化疗/放化疗治疗的晚期BTC患者，高SATr与肿瘤进展风险和不良预后相关。
