UNASSIGNED: A retrospective study of a cohort of 116 patients with unresectable stage III or IV NSCLC with any grade CIP from April 2016 to August 2022 were conducted. To analyze the clinical characteristics of patients with different CIP grades, patients were divided into mild CIP group (grade 1-2, n=49) and severe CIP group (grade 3-5, n=67) according to the grade of CIP. To explore the OS-related risk factors in the severe CIP group, the patients were divided into a good prognosis (GP) group (≥ median OS, n=30) and a poor prognosis (PP) group (< median OS, n=37) based on whether their overall survival (OS) were greater than median OS. Baseline clinical and laboratory data were collected for analysis.
UNASSIGNED: The median OS of all NSCLC patients combined with CIP was 11.4 months (95%CI, 8.070-16.100), The median OS for mild CIP and severe CIP was 22.1 months and 4.4 months respectively (HR=3.076, 95%CI, 1.904-4.970, P<0.0001). The results showed that the most common cause of death among severe CIP patients in the PP group was CIP and the most common cause in the GP group was tumor. The univariate regression analysis showed that suspension of antitumor therapy was a risk factor for poor prognosis (OR=3.598, 95%CI, 1.307-9.905, p=0.013). The multivariate logistic regression analysis showed that suspension of anti-tumor therapy (OR=4.24, 95%CI, 1.067-16.915, p=0.040) and elevated KL-6 (OR=1.002, 95%CI, 1.001-1.002, p<0.001) were independent risk factors for poor prognosis.
UNASSIGNED: In conclusion, patients with severe CIP had a poor prognosis, especially those with elevated KL-6, and the main cause of death is immune checkpoint inhibitor-associated pneumonitis complicated with infection. In addition, anti-tumor therapy for severe CIP patients should be resumed in time and should not be delayed for too long.
■对2016年4月至2022年8月的116例不可切除的III期或IV期NSCLC患者进行回顾性研究。分析不同CIP分级患者的临床特点,根据CIP的等级将患者分为mildCIP组(1-2级,n=49)和重度CIP组(3-5级,n=67)。探讨重度P组OS相关危险因素,将患者分为预后良好(GP)组(≥中位OS,n=30)和预后不良(PP)组(<中位OS,n=37)基于他们的总生存期(OS)是否大于中位OS。收集基线临床和实验室数据用于分析。
■所有合并CIP的NSCLC患者的中位OS为11.4个月(95CI,8.070-16.100),mildCIP和严重CIP的中位OS分别为22.1个月和4.4个月(HR=3.076、95CI,1.904-4.970,P<0.0001)。结果表明,PP组重度CIP患者中最常见的死亡原因是CIP,GP组最常见的死亡原因是肿瘤。单因素回归分析显示暂停抗肿瘤治疗是预后不良的危险因素(OR=3.598,95CI,1.307~9.905,p=0.013)。多因素logistic回归分析显示,暂停抗肿瘤治疗(OR=4.24,95CI,1.067-16.915,p=0.040)和升高的KL-6(OR=1.002,95CI,1.001-1.002,p<0.001)是预后不良的独立危险因素。
■总而言之,重度CIP患者预后不良,尤其是KL-6升高的患者,主要死亡原因是免疫检查点抑制剂相关性肺炎并发感染。此外,重度CIP患者的抗肿瘤治疗应及时恢复,且不应拖延太久.
