BACKGROUND/AIM: The geriatric nutrition risk index (GNRI) is a presumptive prognosticator in a variety of carcinomas. We investigated whether it similarly predicts outcomes of elderly patients with colorectal cancer (CRC).
PATIENTS AND METHODS
A total of 904 older adults (≥65 years) undergoing radical resections of CRC between April 2011 and December 2015 proved eligible for study. Each was grouped by preoperative status (cut-off point, 98) as low-level or normal GNRI, using propensity score matching to compare rates of complications, disease-free survival (DFS), and overall survival (OS).
RESULTS
After matching (n=127, each group), those with low-level (vs. normal) GNRI values experienced significantly more complications (p=0.001), and 5-year survival was significantly poorer (DFS: p=0.006; OS: p=0.002).
CONCLUSION
In elderly patients with resected CRC, preoperative GNRI may have significant prognostic merit.
背景/目的：老年营养风险指数（GNRI）是多种癌症的一种推测性预后指标。我们研究了它是否同样能预测老年结直肠癌（CRC）患者的预后。
患者与方法
2011年4月至2015年12月期间，共有904名接受CRC根治性切除术的老年人（≥65岁）符合研究条件。根据术前状态（临界值为98）将每位患者分为低水平或正常GNRI组，采用倾向评分匹配法比较并发症发生率、无病生存率（DFS）和总生存率（OS）。
结果
匹配后（每组n = 127），GNRI值低水平（与正常水平相比）的患者并发症明显更多（p = 0.001），5年生存率明显更低（DFS：p = 0.006；OS：p = 0.002）。
结论
在接受CRC切除术的老年患者中，术前GNRI可能具有显著的预后价值。
