Pembrolizumab has been approved as first-line treatment for advanced Non-small cell lung cancer (NSCLC) patients with tumors expressing PD-L1 and in the absence of other targetable alterations. However, not all patients that meet these criteria have a durable benefit. In this monocentric study, we aimed at refining the selection of patients based on the expression of immune genes. Forty-six consecutive advanced NSCLC patients treated with pembrolizumab in first-line setting were enrolled. The expression levels of 770 genes involved in the regulation of the immune system was analysed by the nanoString system. PD-L1 expression was evaluated by immunohistochemistry. Patients with durable clinical benefit had a greater infiltration of cytotoxic cells, exhausted CD8, B-cells, CD45, T-cells, CD8 T-cells and NK cells. Immune cell scores such as CD8 T-cell and NK cell were good predictors of durable response with an AUC of 0.82. Among the immune cell markers, XCL1/2 showed the better performance in predicting durable benefit to pembrolizumab, with an AUC of 0.85. Additionally, CD8A, CD8B and EOMES showed a high specificity (>0.86) in identifying patients with a good response to treatment. In the same series, PD-L1 expression levels had an AUC of 0.61. The characterization of tumor microenvironment, even with the use of single markers, can improve patients’ selection for pembrolizumab treatment.

The clinical application of immune checkpoint inhibitors (ICIs) has led to dramatic changes in the treatment strategy for patients with advanced non-small cell lung cancer (NSCLC). Despite the observation of improved overall survival in NSCLC patients treated with ICIs, their efficacy varies greatly among different immune and molecular profiles in tumors. Particularly, the clinical significance of ICIs for oncogene-driven NSCLC has been controversial. In this review, we provide recent clinical and preclinical data focused on the relationship between oncogenic drivers and immunological characteristics and discuss the future direction of immunotherapy in NSCLC patients harboring such genetic alterations

Abstract Background: Non-small cell lung cancer (NSCLC) is the most prevalent type of lung cancer accounting for 80–85% of all lung cancer cases. Various genetic studies have tried to reveal the association of REV3L (Protein reversion less 3-like) gene mutations with cancer, including lung cancer but no such study has been carried out in the population of Jammu and Kashmir (J&K).Methods: The selected REV3L variants were genotyped using the TaqMan allele discrimination assay in 550 subjects (203 NSCLC patients and 347 healthy controls). The association of variants was evaluated by logistic regression.Results: Out of the four REV3L variants genotyped, we found rs1002481, rs462779, and rs465646 significantly associated with NSCLC risk with an Odds Ratio (OR) of 3.5 (1.98–6.3 at 95% CI ), p value = 0.00002; OR = 4.4 (1.8–10.4 at 95% CI ), p value = 0.00075; and OR = 2.4 (1.47–4.008 at 95% CI ), p value = 0.00053, respectively.Conclusion: Our data suggest a strong association of variants rs1002481, rs462779, rs465646 with NSCLC. This association is indicative of a potential role of mutations in the REV3L gene as risk factor for the development of NSCLC in the studied population. Although a first report from any Indian population, these variants have been previously reported to be associated with lung and colorectal cancers in different world populations. These data along with our data supports the notation that these variants can be used as potential prognostic biomarker.
