Colorectal cancer remains a major global health concern. Identifying high-risk patients is crucial for optimizing treatment strategies. The prognostic value of biomarkers, especially considering competing risks, remains unclear. We used a competing risks model to exclude the influence of non-cancer-related mortality and examined FAR as a predictor of recurrence in colorectal cancer.
This retrospective study analyzed 359 patients with stage II or III colorectal cancer from the cecum to the oral side of the peritoneal inversion, all of whom underwent curative resection at Fukui University Hospital. The primary outcome was cancer recurrence. The fibrinogen-albumin ratio (FAR) was assessed using univariate and multivariate analyses, including competing risk models, with a cutoff value of >0.131.
Univariate analysis identified factors significantly associated with poorer outcomes, including T4 stage, gross appearance type 3/4/5 tumors, stage III disease, elevated neutrophil-to-lymphocyte ratio, prognostic nutritional index, carcinoembryonic antigen, and FAR. Multivariate analysis confirmed FAR as an independent prognostic factor. A predictive model combining FAR, stage III disease, and T4 stage demonstrated the best performance based on Akaike information criterion and Bayesian information criterion values.
FAR is a robust prognostic biomarker for colorectal cancer. Incorporating FAR into clinical practice may enable healthcare providers to more accurately stratify high-risk patients, facilitating personalized treatment strategies.
结直肠癌仍然是全球主要的健康问题。识别高危患者对于优化治疗策略至关重要。生物标志物的预后价值,尤其是考虑到竞争风险时,仍不明确。我们使用竞争风险模型排除非癌症相关死亡率的影响,并将纤维蛋白原-白蛋白比率(FAR)作为结直肠癌复发的预测指标进行研究。
这项回顾性研究分析了359例盲肠至腹膜反折口侧的II期或III期结直肠癌患者,他们均在福井大学医院接受了根治性切除术。主要结局是癌症复发。使用单因素和多因素分析评估纤维蛋白原-白蛋白比率(FAR),包括竞争风险模型,临界值设定为>0.131。
单因素分析确定了与较差预后显著相关的因素,包括T4期、大体外观类型为3/4/5的肿瘤、III期疾病、中性粒细胞与淋巴细胞比率升高、预后营养指数、癌胚抗原和FAR。多因素分析证实FAR是一个独立的预后因素。基于赤池信息准则和贝叶斯信息准则值,结合FAR、III期疾病和T4期的预测模型表现最佳。
FAR是结直肠癌强有力的预后生物标志物。将FAR纳入临床实践可能使医疗服务提供者能够更准确地对高危患者进行分层,促进个性化治疗策略的制定。
