Molecular mechanisms of programmed death-ligand 1 (PD-L1) mRNA expression and roles of apoptosis and biomarkers are poorly understood in epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma patients. Thirty-three patients with recurrent postoperative EGFR-mutant lung adenocarcinoma (exon 19 deletion in 16, L858R in 15, G719C in 2 patients) treated with gefitinib were studied. PD-L1 mRNA expression of formalin-fixed paraffin-embedded paratumoral and intratumoral tissues was quantified by PCR. Correlations of PD-L1 mRNA expression with BIM, p53 upregulated modular of apoptosis (PUMA), human epidermal growth factor receptor 2 (HER2), mesenchymal-epithelial transition (MET), EGFR, and vascular endothelial growth factor A (VEGFA) were determined...

PURPOSE: By unlocking anti-tumor immunity, antibodies targeting programmed cell death 1 (PD-1) exhibit impressive clinical results in non-small cell lung cancer, underlining the strong interactions between tumor and immune cells. However, factors that can robustly predict long-lasting responses are still needed. EXPERIMENTAL DESIGN: We performed in depth immune profiling of lung adenocarcinoma using an integrative analysis based on immunohistochemistry, flow-cytometry and transcriptomic data...

Targeted therapy against druggable genetic aberrations has shown a significantly positive response rate and longer survival in various cancers, including lung cancer. In lung adenocarcinoma (LADC), specific thyroxin kinase inhibitors against EGFR mutations and ALK fusions are used as a standard treatment regimen and show significant positive efficacy. On the other hand, targeted therapy against driver gene aberrations has not been adapted yet in small cell lung cancer (SCLC). This is because driver genes and druggable aberrations are rarely identified by next generation sequencing in SCLC...

Treatment of lung cancer has been revolutionized with development of drugs that target key driver mutations and immune checkpoints. Until recently, it was believed that these driver mutations are mutually exclusive. However, few reports have emerged citing the presence of both mutations either synchronously or metachronously. We describe a case report of lung adenocarcinoma harboring two driver mutations in the same tumor cells as well as exhibiting high PDL1 expression. We further discuss the possible association of these driver mutations with PDL1 expression...

REVIEW
Marcin Skrzypski, Jacek Jassem
The majority of stage III NSCLC patients managed with a combination of radiotherapy and chemotherapy will develop a locoregional or distant relapse. Concomitant radiochemotherapy allows for improved local control but has no impact on extrathoracic recurrences. To ameliorate this inefficiency the concept of consolidation treatment has been put forward, whereby systemically active doses of chemotherapy, targeted therapy or immune therapy are administered after completion of radiochemotherapy. Randomized trials failed to provide support for consolidation chemotherapy or anti-EGFR therapies...

We report 2 cases of pulmonary adenocarcinoma mimicking desquamative interstitial pneumonia (DIP) with genetic analysis occurring in a 74-year-old woman and a 76-year-old woman. In both cases, the tumor was mainly composed of discohesive tumor cells, which filled and floated in the alveolar space in a DIP-like pattern. The tumor cells had abnormally large round to oval nuclei with fine chromatin and relatively abundant eosinophilic cytoplasm lacking pigmentation. Immunohistochemically, tumor cells in both cases were positive for CK7, TTF-1, napsin A, E-cadherin, β-catenin, and PD-L1 (one case had high expression and the other had low expression), and negative for CK5/6, CK20, p40, and ALK...

Immune checkpoint blockade targeting the PD-1/PD-L1 axis has recently demonstrated efficacy and promise in cancer treatment. Appropriate biomarker selection is therefore essential for improving treatment efficacy. However, the establishment of PD-L1 assay in pathology laboratories is complicated by the presence of multiple testing platforms using different scoring systems. Here we assessed the PD-L1 expression in 713 consecutive non-small cell lung carcinomas by four commercially available PD-L1 immunohistochemical assays, namely, 22C3, 28-8, SP142 and SP263...

BACKGROUND: Primary adenocarcinoma of the anal canal is a rare and aggressive gastrointestinal disease with unclear pathogenesis. Because of its rarity, no clear clinical practice guideline has been defined and a targeted therapeutic armamentarium has yet to be developed. The present article aimed at addressing this information gap by in-depth characterising the anal glandular neoplasms at the histologic, immunologic, genomic and epidemiologic levels. METHODS: In this multi-institutional study, we first examined the histological features displayed by each collected tumour (n = 74) and analysed their etiological relationship with human papillomavirus (HPV) infection...

Immunotherapy targeting the programmed cell death-1 (PD-1) and programmed cell death-ligand 1 (PD-L1) pathway has emerged as an effective treatment for lung cancer patients. It is important to evaluate the practicality of PD-L1 testing in real-world practice. A total of 211 non-small cell lung cancer patients were enrolled to detect 5 driver mutations and PD-L1 status (22C3 and SP263 assays) and to evaluate the characteristics of PD-L1 expression and its predictive value of immunotherapy. The PD-L1 positive (≥1%) and strong positive (≥50%) rate by SP263 assay was 27...

Urachal cancer (UrC) is a rare but aggressive malignancy often diagnosed in advanced stages requiring systemic treatment. Although cytotoxic chemotherapy is of limited effectiveness, prospective clinical studies can hardly be conducted. Targeted therapeutic treatment approaches and potentially immunotherapy based on a biological rationale may provide an alternative strategy. We therefore subjected 70 urachal adenocarcinomas to targeted next-generation sequencing, conducted in situ and immunohistochemical analyses (including PD-L1 and DNA mismatch repair proteins (MMR)) and evaluated the microsatellite instability (MSI) status...

Background First-line therapy for advanced non-small-cell lung cancer (NSCLC) that lacks targetable mutations is platinum-based chemotherapy. Among patients with a tumor proportion score for programmed death ligand 1 (PD-L1) of 50% or greater, pembrolizumab has replaced cytotoxic chemotherapy as the first-line treatment of choice. The addition of pembrolizumab to chemotherapy resulted in significantly higher rates of response and longer progression-free survival than chemotherapy alone in a phase 2 trial. Methods In this double-blind, phase 3 trial, we randomly assigned (in a 2:1 ratio) 616 patients with metastatic nonsquamous NSCLC without sensitizing EGFR or ALK mutations who had received no previous treatment for metastatic disease to receive pemetrexed and a platinum-based drug plus either 200 mg of pembrolizumab or placebo every 3 weeks for 4 cycles, followed by pembrolizumab or placebo for up to a total of 35 cycles plus pemetrexed maintenance therapy...

Background: The aberrant status of target genes and their associations with clinicopathologic characteristics are still unclear in primary lung adenocarcinoma. Methods: The common mutations and translocations of nine target genes were evaluated in 1,247 specimens of surgically-resected primary lung adenocarcinoma. Immunohistochemistry was used to analyze the expressions of programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1) in 731 specimens. The frequency of the aberrations and their associations with clinicopathologic characteristics were analyzed...

BACKGROUND/AIM: African Americans (AA) have the highest incidence and mortality of any racial/ethnic group in the US for most cancer types. Heterogeneity in the molecular biology of cancer, as a contributing factor to this disparity, is poorly understood. To address this gap in knowledge, we explored the molecular landscape of colorectal cancer (CRC), non-small cell lung cancer (NSCLC) and high-grade glioma (HGG) from 271 AA and 636 Caucasian (CC) cases. MATERIALS AND METHODS: DNA from formalin-fixed paraffin-embedded tumors was sequenced using next-generation sequencing...

OBJECTIVES: Expression of programmed cell death-ligand 1 (PD-L1) has been associated with clinical outcome of programmed cell death-1 (PD-1) pathway blockade in non-small cell lung cancer (NSCLC). The PD-L1 IHC 22C3 pharmDx assay, the only companion diagnostic for pembrolizumab therapy, has revealed that ∼30% of all NSCLCs express PD-L1 at a high level. The frequency of high PD-L1 expression in NSCLCs with known driver oncogenes has remained unclear, however. MATERIALS AND METHODS: We retrospectively evaluated PD-L1 expression with the 22C3 assay in tumor tissue of 80 lung adenocarcinoma patients including 71 with EGFR mutations and 9 with ALK rearrangements, all of whom were treated with corresponding tyrosine kinase inhibitors (TKIs)...

OBJECTIVES: Programmed death-1 (PD-1) and programmed death-ligand 1 (PD-L1) inhibitors have been approved as a standard therapy for metastatic non-small cell lung cancer (NSCLC). Although PD-L1 expression serves as a predictive biomarker for the efficacy of immunotherapy, there are no established biomarkers to predict the expression of PD-L1. The inflammatory markers C-reactive protein (CRP) and neutrophil-lymphocyte ratio (NLR) were recently shown to predict the efficacy of nivolumab for NSCLC patients...
