We evaluated the prognostic potential of the combination of platelet count and neutrophil to lymphocyte ratio (COP-NLR) in patients with advanced head and neck cancer.
We proposed a modified COP-NLR scoring system defined as follows: score 0 (platelet count level <300 × 10 /L and NLR <3); score 1 (platelet count level ≥300 × 10 /L and NLR <3); and score 2 (NLR ≥3). We assessed whether the modified scoring system had better performance as an indicator of prognosis than the existing COP-NLR scoring system (original and 4-group scores).
A total of 248 patients were enrolled. The Akaike Information Criterion value with the modified COP-NLR score was the smallest among the 3 models. The 3-year survival rates according to the modified COP-NLR scores of 0, 1, and 2 were 80.6%, 59.9%, and 23.8%, respectively.
The modified COP-NLR score is a useful prognostic marker in patients with advanced head and neck cancer.
我们评估了血小板计数与中性粒细胞与淋巴细胞比值（COP-NLR）联合在晚期头颈部癌症患者中的预后预测能力。
我们提出了一种改良的 COP-NLR 评分系统，定义如下：评分 0（血小板计数水平<300×10 /L 和 NLR<3）；评分 1（血小板计数水平≥300×10 /L 和 NLR<3）；评分 2（NLR≥3）。我们评估了改良评分系统作为预后指标的表现是否优于现有的 COP-NLR 评分系统（原始和 4 组评分）。
共纳入 248 例患者。改良 COP-NLR 评分的赤池信息量准则值在 3 种模型中最小。改良 COP-NLR 评分 0、1 和 2 对应的 3 年生存率分别为 80.6%、59.9%和 23.8%。
改良的 COP-NLR 评分是晚期头颈部癌症患者有用的预后标志物。
