To evaluate the prognostic value of pre-treatment prognostic-nutritional index (PNI) in patients with HPV-negative head and neck squamous cell carcinoma (HNSCC).
A multi-institutional retrospective series of HPV-negative, Stages II-IVB, HNSCCs treated with upfront surgery was evaluated. Correlation of pre-operative blood markers and PNI with 5-year overall (OS) and relapse-free (RFS) survival was tested using linear and restricted cubic spline models, as appropriate. The independent prognostic effect of patient-related features was assessed with multivariable models.
The analysis was conducted on 542 patients. PNI ≥ 49.6 (HR = 0.52; 95% CI, 0.37-0.74) and Neutrophil-to-Lymphocyte Ratio (NLR) > 4.2 (HR = 1.58; 95% CI, 1.06-2.35) confirmed to be independent prognosticators of OS, whereas only PNI ≥ 49.6 (HR = 0.44; 95% CI, 0.29-0.66) was independently associated with RFS. Among pre-operative blood parameters, only higher values of albuninaemia and lymphocyte count (> 1.08 x 10/microL), and undetectable basophile count (= 0 10/microL) were independently associated with better OS and RFS.
PNI represents a reliable prognostic tool providing an independent measure of pre-operative immuno-metabolic performance. Its validity is supported by the independent prognostic role of albuminaemia and lymphocyte count, from which it is derived.
评估治疗前预后营养指数（PNI）在 HPV 阴性头颈部鳞状细胞癌（HNSCC）患者中的预后价值。
评估了多机构 HPV 阴性、II-IVB 期、接受直接手术治疗的 HNSCC 的回顾性系列。使用线性和限制性立方样条模型适当评估术前血液标志物和 PNI 与 5 年总生存期（OS）和无复发生存期（RFS）的相关性。使用多变量模型评估患者相关特征的独立预后作用。
对 542 名患者进行了分析。PNI≥49.6（HR=0.52；95%CI，0.37-0.74）和中性粒细胞与淋巴细胞比值（NLR）>4.2（HR=1.58；95%CI，1.06-2.35）被确认为 OS 的独立预后因素，而只有 PNI≥49.6（HR=0.44；95%CI，0.29-0.66）与 RFS 独立相关。在术前血液参数中，只有更高的白蛋白血症和淋巴细胞计数值（>1.08×10/μL）和无法检测到的嗜碱性粒细胞计数（=0 10/μL）与更好的 OS 和 RFS 独立相关。
PNI 是一种可靠的预后工具，提供了术前免疫代谢性能的独立衡量标准。其有效性得到白蛋白血症和淋巴细胞计数的独立预后作用的支持，这是它所衍生的。
