Objective To analyze the prognostic significance of the pretreatment platelet/lymphocyte ratio (PLR) for targeted therapy in patients with epidermal growth factor receptor (EGFR)-mutated non-small-cell lung cancer (NSCLC). Methods We conducted a retrospective study of 96 patients with EGFR-mutated advanced NSCLC who were treated at Dongguan People’s Hospital, Southern Medical University from May 2014 to December 2017. All patients received EGFR-targeted therapy until disease progression, unacceptable toxicity, or other factors. Approximately 3 days before the initial treatment, data including a detailed clinical history, physical examination, radiographic results, pathological diagnosis, and laboratory parameters including complete blood cell counts and albumin levels were evaluated. Results Patients in the PLR ≥ 190 group had shorter progression-free survival (PFS) than those in the PLR < 190 group. Furthermore, the 1-year PFS rate was worse in the PLR ≥ 190 group than in the PLR< 190 group. Multivariate analysis indicated the possible role of PLR as a prognostic factor for patients with advanced NSCLC who received EGFR-targeted therapy. Conclusions Pretreatment PLR may be an independent prognostic factor for patients with NSCLC receiving EGFR tyrosine kinase inhibitor treatment. Further studies are needed to identify the impact of PLR on EGFR-mutated NSCLC.

Purpose Lung cancer is one of the leading causes of cancer-related death worldwide and, although targeted therapy with tyrosine kinase inhibitors has dramatically improved the rates of response and survival in advanced EGFR-mutated adenocarcinoma, the overall outcome remains unsatisfactory. Therefore, new prognostic factors, preferably simple, inexpensive, and easy to reproduce on a large scale, are needed. We performed a retrospective analysis of our database including 63 western Caucasian patients with advanced EGFR-mutated lung adenocarcinoma and receiving gefitinib, erlotinib, or afatinib as first- or second-line therapy. Several studies demonstrated a strong link between elevated neutrophil-to-lymphocyte ratio (NLR) and poor prognosis both in early and advanced stages of non-small-cell lung cancer (NSCLC). Methods From January 2011 to December 2015, 63 consecutive elegible patients with advanced EGFR-mutated NSCLC were included in this analysis from 5 institutions. The NLR was derived from the absolute neutrophil and the absolute lymphocyte counts of a full blood count and the cutoff value was determined according to the mean NLR level. Results Despite the small sample analyzed, we found that NLR has a prognostic role for progression-free survival (PFS) and overall survival (OS), reaching a statistically significant difference with a better PFS and OS in the lower NLR group. Conclusions Pretreatment NLR seems to represent a reliable, simple, and easy to reproduce laboratory tool to predict outcome and response to cancer therapies in this setting of Western Caucasian patients with EGFR-mutated NSCLC.

Lymphocyte Ratio

46 Background: Neutrophil to lymphocyte ratio (NLR) is known to be prognostic for patients with various types of cancer, including those who are treated with immune checkpoint inhibitors (ICI). We evaluated NLR at baseline and during early phase of treatment for patients with advanced non-small cell lung cancer (NSCLC) who received ICI to evaluate its prognostic value in first line ICI therapy and its relationship to programmed death-ligand 1 (PD-L1) expression. Methods: We retrospectively evaluated patients with advanced NSCLC who received ICI as first line therapy from 2016 to 2018. NLR was calculated as ratio of absolute neutrophil/lymphocyte counts and was consider elevated if ≥5. PD-L1 expression by immunohistochemistry was performed as standard of care with 22C3 antibody. Kaplan Meier analysis was used for survival. Wilcoxon-Mann-Whitney test was used to evaluate PD-L1 expression between groups. All Calculation was performed using SAS V9.4. Results: A total of 78 patients were included in this study; 28 received pembrolizumab monotherapy, 45 received pembrolizumab, carboplatin, and pemetrexed, and 5 received other pembrolizumab combinations. Patients with baseline NLR < 5 before initiating ICI had median estimated OS of 46.1 months (79.4% patient still alive and 95% CI not reached) compare to median OS of 10.7 months (95% CI lower limit 6.4 and upper limit not reached) for patients with NLR ≥5, P < 0.001. Similar association between NLR and OS can be seen when NLR were repeated immediate before the cycle 2 with P = 0.001. We observed an association between baseline NLR and PD-L1 expression. The median PD-L1 tumor proportion score (TPS) was 60% (Interquartile Range 1-80) for patients with baseline NLR < 5 vs 20% (IQR 0-60) for patients with NLR ≥5, P = 0.037. Conclusions: We confirmed the prognostic value of NLR for patients with advanced NSCLC at baseline and during early treatment in patients with NSCLC receiving first line ICI treatment. We also found an association between elevated NLR and lower PD-L1 expression. Future study with larger cohort is still needed to further delineate these relationships.

Potential Target

Purpose: Non-small cell lung cancer (NSCLC) is the leading worldwide source of cancer-related deaths. Although some drugs targeting epidermal growth factor receptor (EGFR) mutations have been developed, most advanced NSCLC is still incurable and new targets for anticancer drugs are in demand. BRCA1-associated protein-1 (BAP1) is a component of the ubiquitin proteasome system (UPS). UPS has emerged as a potential target for anticancer drugs. The aim of the present study was to investigate the expression of BAP1 protein in patients with NSCLC. Methods: BAP1 expression was measured using Western blot analysis in 103 cases patients with advanced NSCLC. Results: Results revealed 49 (47.5%) patients were classified with high expression of BAP1. Squamous cell carcinomas were more likely to be observed in BAP1 high expressers compared with adenocarcinomas (55.8% vs. 32.3%, p= 0.001). High BAP1 expression was associated with no lymph node metastasis (p= 0.002). There was also a significant association between BAP1 expression and histological type (p= 0.014), while expression of BAP1 was not correlated with other clinical or pathological characteristics. Kaplan-Meier survival analysis showed that patients with high BAP1 expression had a longer median survival compared with patients with low BAP1 expression (23.2 vs. 14.7 months, p= 0.021). Multivariate analysis revealed that high BAP1 expression was an independent lower risk for all 103 patients (HR = 0.61, 95% CI 0.32-0.71, p = 0.003). Conclusions: BAP1 may be a useful prognostic factor of NSCLC patients and potential target for anticancer drugs.
