Background: Immune checkpoint inhibitors (ICI)-based combination strategies have improved the survival outcomes in advanced non-small cell lung cancers; however, data regarding their efficacy remains limited for uncommon histological types, including large-cell carcinoma (LCC) and large-cell neuroendocrine carcinoma (LCNEC).
Methods: We retrospectively analyzed a total of 60 patients with advanced LCC and LCNEC - 37 treatment-naïve and 23 pre-treated - who received pembrolizumab with or without chemotherapy. Treatment and survival outcomes were analyzed.
Ribonucleotide reductase (RNR) is the key enzyme that catalyzes the production of deoxyribonucleotides (dNTPs) for DNA replication and it is also essential for cancer cell proliferation. As the RNR inhibitor, Gemcitabine is widely used in cancer therapies, however, resistance limits its therapeutic efficacy and curative potential. Here, we identified that mTORC2 is a main driver of gemcitabine resistance in non-small cell lung cancers (NSCLC).
View Article and Find Full Text PDFIntroduction: ROS1-rearranged non-small cell lung cancer (NSCLC) has demonstrated promising response to lorlatinib; however, no targeted therapy is available after failure of lorlatinib and information on acquired resistance mechanisms mediating lorlatinib resistance among ROS1-rearranged NSCLC patients is limited. We report a ROS1-rearranged NSCLC patient who responded to immunochemotherapy after acquisition of ROS1 G2032K-mediated lorlatinib resistance.
Methods: Next-generation sequencing (NGS) was performed on supraclavicular lymph nodes (SLN) and blood samples obtained from the 53-year old male patient with advanced CD74-ROS1-rearranged NSCLC.
