Hemoglobin, albumin, lymphocyte, and platelet score and neutrophil-to-lymphocyte ratio are novel significant prognostic factors for patients with small-cell lung cancer undergoing chemotherapy

Objective: The hemoglobin, albumin, lymphocyte, and platelet (HALP) score, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) are the important prognostic markers in some tumor types. This study aimed to evaluate the prognostic impact of pretreatment using HALP, NLR, and PLR for patients with small-cell lung cancer (SCLC), who were undergoing chemotherapy. Materials and Methods: In this retrospective study, 335 patients with SCLC were included between 2016 and 2018. The cutoff values for HALP, NLR, and PLR were defined using X-tile software. Survival was analyzed by the Kaplan–Meier method, with differences analyzed through the log-rank test. The multivariate Cox proportional hazard model was used to evaluate the prognostic significance of HALP, NLR, and PLR for SCLC. Results: The median follow-up period was 27.1 months (range: 0.5–46.2 months). Based on the Kaplan–Meier curve analysis, it was noticed that the low pretreatment HALP (≤18.6), high pretreatment NLR (>2.4), and high PLR (>191.6) were significantly associated with worse overall survival (OS) (P = 0.009, 0.001, and 0.033, respectively). Cox multivariate analysis demonstrated that low pretreatment HALP and high pretreatment NLR were the independent prognostic factors for worse OS (hazard ratio [HR] = 1.468, 95% confidence interval [CI]: 1.004–2.146, P = 0.047; HR = 0.722, 95% CI: 0.542–0.960, P = 0.025, respectively). Conclusion: HALP and NLR were the independent prognostic factors of OS for SCLC patients undergoing chemotherapy

Induction chemotherapy for unresectable Stage III non-small-cell lung cancer may improve survival of induction chemotherapy responders as predicted by elevated levels of carcinoembryonic antigen and cytokeratin fragment 19 and classification as stage N3 cancer

Aims: The aim of this study is to investigate patients with unresectable Stage III non-small-cell lung cancer (NSCLC) receiving radiotherapy with induction and concurrent pemetrexed or docetaxel plus cisplatin (PP/DP) chemotherapy and to identify the subgroup most likely to benefit from induction chemotherapy (IC). Subjects and Methods: Patients with unresectable measurable Stage III NSCLC received two cycles of PP/DP IC followed by concurrent chemoradiotherapy at a dose of 60–66 Gy. Statistical Analysis Used: Cox regression analysis was performed to evaluate the prognostic factors for survival; logistic regression analysis was used to evaluate the predictors for response to IC, and the receiver operating characteristic curves were used to evaluate the independent factors predicting response. Results: Eighty patients were included; the median survival time (MST) was 22.1 months. Partial response (PR) to IC was an independent prognostic factor for overall survival. For patients in the PR and stable disease groups, the MST was 36.7 and 19.5 months, respectively. The independent predictors of PR to IC included classification as stage N3 cancer, baseline carcinoembryonic antigen (CEA) levels >10 ng/ml, and cytokeratin fragment 19 (CYFRA21-1) levels >6 ng/ml. With each additional independent predictor, the likelihood of having have PR to IC increased. Conclusions: Radiotherapy with induction and concurrent PP/DP chemotherapy is feasible for patients with unresectable Stage III NSCLC. IC may improve the survival of IC responders, as predicted by elevated CEA and CYFRA21-1 levels and classification as stage N3 cancer. Additional randomized trials on IC may consider these predictors to tailor individualized treatments
