Real world prognostic utility of platelet lymphocyte ratio and nutritional status in first-line immunotherapy response in stage IV non-small cell lung cancer
Background
Elevated platelet lymphocyte ratio (PLR) and low body mass index (BMI) are associated with inferior survival in non-small cell lung cancer (NSCLC) patients receiving immunotherapy (IO). We evaluated real-world prognostic utility of PLR, BMI, and albumin level in stage IV NSCLC patients receiving first line (1L) IO.
Methods
We identified 75 stage IV patients who received 1L IO therapy at USC Norris Comprehensive Cancer Center and Los Angeles General Medical Center from 2015 to 2022. The primary outcome was overall survival (OS) from time of IO with attention to pre-treatment BMI < 22, albumin < 3.5 g/dL, and PLR > 180.
Results
Median age was 66.5 years with 49 (65.3%) males. 25 (33.3%) had BMI < 22. 45/75 (60%) had PLR > 180. Patients with BMI < 22 had inferior OS (13.1 months (m) vs. 37.4 m in BMI > 28, p-value = 0.042) along with patients with albumin<3.5 g/dL (OS: 2.8 m vs. 14.6 m, p-value = 0.0027), and patients with PLR>180 (OS: 8.7 m vs. 23.0 m, p = 0.028). Composite BMI < 22, PLR > 180 had the worst OS, p-value = 0.0331. Multivariate analysis controlling for age, smoking, gender, PD-L1 tumor proportion score (TPS), and histology (adenocarcinoma, squamous, adenosquamous, and large cell) showed that BMI (HR: 0.8726, 95% CI: 0.7892–0.954) and PLR > 180 (HR: 2.48, 95% CI: 1.076–6.055) were significant in OS mortality risk.
Conclusion
Patients with a composite of BMI < 22, albumin < 3.5 g/dL, and PLR > 180 had significantly worse OS. This highlights the importance of screening for poor nutritional status and high PLR to better inform stage IV NSCLC patients receiving IO therapy of their prognosis and supportive care.
MicroAbstract
We evaluated real-world prognostic utility of platelet lymphocyte ratio (PLR), body mass index (BMI), and albumin level in 75 Stage IV NSCLC patients receiving first line IO. Patients with a composite of BMI < 22, albumin < 3.5 g/dL, and PLR > 180 had significantly worse OS. This highlights the importance of screening for poor nutritional status and high PLR to better inform stage IV NSCLC patients of their prognosis and to emphasize supportive care needs.
期刊介绍：
Cancer Treatment and Research Communications is an international peer-reviewed publication dedicated to providing comprehensive basic, translational, and clinical oncology research. The journal is devoted to articles on detection, diagnosis, prevention, policy, and treatment of cancer and provides a global forum for the nurturing and development of future generations of oncology scientists. Cancer Treatment and Research Communications publishes comprehensive reviews and original studies describing various aspects of basic through clinical research of all tumor types. The journal also accepts clinical studies in oncology, with an emphasis on prospective early phase clinical trials. Specific areas of interest include basic, translational, and clinical research and mechanistic approaches; cancer biology; molecular carcinogenesis; genetics and genomics; stem cell and developmental biology; immunology; molecular and cellular oncology; systems biology; drug sensitivity and resistance; gene and antisense therapy; pathology, markers, and prognostic indicators; chemoprevention strategies; multimodality therapy; cancer policy; and integration of various approaches. Our mission is to be the premier source of relevant information through promoting excellence in research and facilitating the timely translation of that science to health care and clinical practice.
