Detection of tumor antigens and tumor-antigen specific T cells in NSCLC patients: correlation of the quality of T cell responses with NSCLC subtype.

Detection of tumor antigens and tumor-antigen specific T cells in NSCLC patients: correlation of the quality of T cell responses with NSCLC subtype. Immunol Lett. 2020 Jan 10;: Authors: Ondrej P, Hradilova Nada P, Mysiková D, Kutna B, Mrazkova H, Lischke R, Spisek R, Adkins I Abstract Allogeneic cancer cell lines serve as universal source of tumor-associated antigens in cancer vaccines. Immunogenic high hydrostatic pressure-killed cancer cells derived from cell lines can be used for the generation of dendritic cell (DC)-based active cellular immunotherapy of non-small cell lung cancer (NSCLC). We investigated the expression of 12 known NSCLC tumor-associated antigens (TAA) (CEA, MAGE-A1, MAGE-A3, MAGE-A4, PRAME, hTERT, HER2, MUC1, Survivin, STEAP1, SOX2 and NY-ESO-1) in 6 NSCLC cell lines as candidates for the generation of DC-based lung cancer vaccine. We showed that the selected antigenic profile of these cell lines overlaps to various degrees with that of primary NSCLC tumors (n = 52), indicating that 4 out of 6 NSCLC cell lines would be suitable for DC-based vaccine generation. We further investigated the presence of TAA-specific T cells in blood of NSCLC patients (n = 32) using commercially available peptide mixes in an in vitro stimulation assay. IFN-γ+CD8+ and IFN-γ+CD4+ T cell responses to all antigens were detected in NSCLC patients. Interestingly, despite higher TAA expression in squamous cell carc...

CONCLUSIONS: Based on these results, 8.1% of Mexican general population without a history of liver disease is at high risk of having advanced liver fibrosis and complications and death derived from cardiovascular disease and cirrhosis. Most of them showed normal ALT serum levels. PMID: 32063504 [PubMed - as supplied by publisher]

Authors: Meunier L, Larrey D Abstract Some drugs may induce hepatotoxic lesions, such as steatosis or steatohepatitis found in Non-Alcoholic Fatty Liver Disease (NAFLD). Among these drugs there are some anti-tumoral molecules, such as methotrexate, 5-fluorouracil, irinotecan, tamoxifen and l-asparaginase. The hepatotoxic phenotype developed from treatment with such drugs is known as "CASH" for "Chemotherapy-induced Acute Steatohepatitis". The mechanism of toxicity is essentially based on mitochondrial toxicity. These lesions are chronic and often reversible when the treatment is stopped. Contrib...

Treatment of unresectable hepatocellular carcinoma (HCC) is complex, and there is limited consensus on the optimal nonsurgical management strategy. This is further complicated by new technologies and locoregional therapies (LRTs) that continue to evolve over time. Several medical specialists are involved in HCC diagnosis and treatment, and treatment strategies are often dictated by consulting physicians ’ specialties, rather than by evidence-based consensus. The most recent National Comprehensive Cancer Network Clinical Practice Guidelines recommend ablation approaches for tumors 5 cm in size (1).

Gena Cook learned to swim three months before competing in her first triathlon. She was 40. Not only did she not drown, she finished in the top five in her age group. “It is an example of the challenges I have sought to stretch me, that helped me take the biggest risk of all in starting Navigating Cancer,” she said. “I left behind all the comforts of a secure, well-paying job for the simple reason that I wanted to improve patient care for cancer patients. ” Navigating Cancer, which Cook…

Despite advances in the development of strategies for treating EC, prognosis of the disease remains unsatisfactory, especially for advanced EC. The aim of this study was to identify novel genes that can be used as potential biomarkers for identifying the prognosis of EC and to construct a novel risk stratification using these genes. Me...

Abstract Non-small cell lung cancers (NSCLCs) frequently express estrogen receptor (ER) β, and estrogen signaling is active in many lung tumors. We investigated the ability of genes contained in the prediction analysis of microarray 50 (PAM50) breast cancer risk predictor gene signature to provide prognostic information in NSCLC. Supervised principal component analysis of mRNA expression data was used to evaluate the ability of the PAM50 panel to provide prognostic information in a stage I NSCLC cohort, in an all-stage NSCLC cohort, and in The Cancer Genome Atlas data. Immunohistochemistry was used to determi...

Introduction: Gene amplification is an important genetic change in cancer cells. We investigated the prevalence, clinicopathological characteristics, and prognostic value of NKX2-1 (also known as TTF-1), SETDB1, MET, HER2, SOX2, FGFR1, and PIK3CA amplification in Japanese patients with non–small-cell lung cancer (NSCLC). Methods: The copy numbers of the seven above-mentioned genes were assessed using fluorescence in situ hybridization in a tissue microarray containing 282 surgically resected NSCLC specimens (164 adenocarcinoma [AC], 99 squamous cell carcinoma [SCC], and 19 others). Clinicopathological information wer...
