Predictive markers of response to immune checkpoint inhibitor rechallenge in metastatic non-small cell lung cancer.

Aim: The present study aims to evaluate the efficacy of rechallenge with immune checkpoint inhibitors (ICIs) compared to chemotherapy and the predictive role of clinical parameters in non-small cell lung cancer (NSCLC) patients who were rechallenged.

Methods: The study included 113 metastatic NSCLC patients who had initially responded to ICIs and platinum-based chemotherapy, either in combination in the first line or sequentially in the first and second line, but later experienced disease progression. Of those patients, 52 later received ICI rechallenge and 61 were exposed to chemotherapy.

Response to trametinib, hydroxychloroquine, and bevacizumab in a young woman with -mutated metastatic intrahepatic cholangiocarcinoma: a case report.

Systemic chemotherapy is the main treatment option for patients with advanced intrahepatic cholangiocarcinoma (iCCA), however, its efficacy is limited. Herein, we report a young patient with -mutated chemoresistant metastatic iCCA, who received second-line therapy with a combination of trametinib (MEK1/2 inhibitor), hydroxychloroquine (autophagy inhibitor), and bevacizumab (angiogenesis inhibitor). A significant response was achieved during therapy, resulting in a 25% decrease in the size of tumor lesions after 2 months of treatment and an improvement in the patient's condition.

Inflammatory and autoimmune predictive markers of response to anti-PD-1/PD-L1 therapy in NSCLC and melanoma.

Immune checkpoint inhibitors (ICI) are a standard in cancer therapy, but few patients respond to the treatment. The aim of the present study was the determination of immunological markers for monitoring response to ICI. The present study included 74 patients receiving ICI in subsequent [group 1; non-small cell lung cancer (NSCLC)] and first-line setting (group 2; melanoma) and 30 patients with NSCLC receiving first-line chemotherapy.

Vimentin as antigenic target in autoimmunity: A comprehensive review.

Vimentin is a protein of intermediate filament family, which is expressed in all mesenchymal cells. Vimentin plays a key role in the physiology of the cell, cellular interactions and the functioning of the immune system. Post-translationally modified and native forms of vimentin are involved in the pathogenesis of inflammation and many autoimmune diseases: rheumatoid arthritis, sarcoidosis, systemic lupus erythematosus, antiphospholipid syndrome, Crohn's disease, ankylosing spondyloarthritis and idiopathic pulmonary fibrosis.
