Clinical characteristics and prognostic impact of immune checkpoint inhibitor-associated myocarditis in advanced non-small cell lung cancer.

Myocarditis is a rare immune-related adverse events (irAEs) with high mortality rates, with few reports on its clinical characteristics and prognostic impact. This study designed to explore the associations between cardiac parameters and outcomes of myocarditis in advanced non-small cell lung cancer (NSCLC) who treated with immune checkpoint inhibitor (ICI). Fourteen patients diagnosed with ICI-associated myocarditis by clinicians were admitted to the study analysis.

Expert consensus on the diagnosis and treatment of RET gene fusion non-small cell lung cancer in China.

The rearranged during transfection (RET) gene is one of the receptor tyrosine kinases and cell-surface molecules responsible for transmitting signals that regulate cell growth and differentiation. In non-small cell lung cancer (NSCLC), RET fusion is a rare driver gene alteration associated with a poor prognosis. Fortunately, two selective RET inhibitors (sRETi), namely pralsetinib and selpercatinib, have been approved for treating RET fusion NSCLC due to their remarkable efficacy and safety profiles.

Chinese expert consensus on the diagnosis and treatment of malignant pleural mesothelioma.

Malignant pleural mesothelioma (MPM) is a malignant tumor originating from the pleura, and its incidence has been increasing in recent years. Due to the insidious onset and strong local invasiveness of MPM, most patients are diagnosed in the late stage and early screening and treatment for high-risk populations are crucial. The treatment of MPM mainly includes surgery, chemotherapy, and radiotherapy.

Chinese expert consensus on the diagnosis and treatment of thymic epithelial tumors.

Thymic epithelial tumors (TETs) are a relatively rare type of thoracic tumor, accounting for less than 1% of all tumors. The incidence of TETs is about 3.93/10000 in China, slightly higher than that of European and American countries.

The study included 95 patients with KRAS-mutant advanced NSCLC.

Response and acquired resistance to MET inhibitors in de novo MET fusion-positive advanced non-small cell lung cancer.

Objectives: De novo mesenchymal-to-epithelial transition (MET) gene fusions in non-small cell lung cancer (NSCLC) are a promising target for MET tyrosine kinase inhibitors (TKIs). We aimed to examine the response to targeted therapy with MET TKIs and resistance mechanisms in de novo MET fusion-positive NSCLC as these have not been comprehensively explored.

Materials And Methods: We examined the MET fusions in 4,429 patients with advanced-stage NSCLC using targeted next-generation sequencing and validated the results using RT-PCR.

Chinese expert consensus on the diagnosis and treatment of HER2-altered non-small cell lung cancer.

Human epidermal growth factor receptor 2 (HER2) possesses tyrosine kinase activity and participates in cell growth, differentiation and migration, and survival. Its alterations, mainly including mutations, amplifications, and overexpression are associated with poor prognosis and are one of the major drivers in non-small cell lung cancer (NSCLC). Several clinical trials had been investigating on the treatments of HER2-altered NSCLC, including conventional chemotherapy, programmed death 1 (PD-1) inhibitors, tyrosine kinase inhibitors (TKIs) and antibody-drug conjugates (ADCs), however, the results were either disappointing or encouraging, but inconsistent.

The prognostic impact of immune checkpoint inhibitors for the treatment of pulmonary sarcomatoid carcinoma: A multicenter retrospective study.

Pulmonary sarcomatoid carcinoma (PSC) is an aggressive and poorly differentiated type of non-small cell lung carcinoma. Because of the rarity of PSC, the efficacy and toxicity of immunotherapy remain unclear. Hence, the aim of this study was to evaluate the efficacy and safety of immune checkpoint inhibitors (ICIs) for the treatment of advanced PSC.

Chinese expert consensus on the multidisciplinary management of pneumonitis associated with immune checkpoint inhibitor.

Immune checkpoint inhibitors (ICIs) have successfully treated a number of different types of cancer, which is of great significance for cancer treatment. With the widespread use of ICIs in clinical practice, the increasing checkpoint inhibitor pneumonia (CIP) will be a challenge to clinicians. To guide the diagnosis and treatment of CIP, we conducted in-depth discussions based on the latest evidence, forming a consensus among Chinese experts on the multidisciplinary management of CIP.

Expert consensus on the diagnosis and treatment of NTRK gene fusion solid tumors in China.

Gene fusions can drive tumor development for multiple types of cancer. Currently, many drugs targeting gene fusions are being approved for clinical application. At present, tyrosine receptor kinase (TRK) inhibitors targeting neurotrophic tyrosine receptor kinase (NTRK) gene fusions are among the first "tumor agnostic" drugs approved for pan-cancer use.

Efficacy and safety of maintenance immune checkpoint inhibitors with or without pemetrexed in advanced non-squamous non-small cell lung cancer: a retrospective study.

Background: Advanced non-squamous non-small cell lung cancer (NS-NSCLC) patients without driver gene mutations are usually treated with immune checkpoint inhibitors (ICIs) plus pemetrexed as maintenance therapy after first-line ICIs plus 4-6 cycles of pemetrexed/platinum. Some patients in the real world receive ICIs monotherapy as maintenance therapy. No clinical study has compared the efficacy and safety of ICIs with or without pemetrexed as maintenance therapy.

Clinicopathological features and resistance mechanisms in HIP1-ALK-rearranged lung cancer: A multicenter study.

Anaplastic lymphoma kinase (ALK)-rearranged non-small cell lung cancer (NSCLC) respond well to ALK tyrosine kinase inhibitors (TKIs), and echinoderm microtubule-associated protein-like 4 (EML4)-ALK-rearranged NSCLC accounts for the majority of those patients. However, few studies have evaluated ALK-TKIs treatment for patients with huntingtin-interacting protein 1 (HIP1)-ALK fusions. This retrospective study evaluated the clinicopathological characteristics, genomic features, response to ALK-TKIs, and resistance mechanisms in 11 cases with HIP1-ALK fusions from five Chinese centers.

Genomic alterations and clinical outcomes in patients with lung adenocarcinoma with transformation to small cell lung cancer after treatment with EGFR tyrosine kinase inhibitors: A multicenter retrospective study.

Background: Transformation to small cell lung cancer (SCLC) is a resistance mechanism to tyrosine kinase inhibitor (TKI) treatment that develops in lung adenocarcinoma. The genomic and treatment outcomes in these populations have not been comprehensively reported in China.

Methods: We performed a retrospective study analyzing patients with advanced non-SCLC (NSCLC) from eight sites who were diagnosed with SCLC transformation after receiving epidermal growth factor receptor (EGFR)-TKI treatment including first/second- or third-generation EGFR-TKIs.

DGM-CM6: A New Model to Predict Distant Recurrence Risk in Operable Endocrine-Responsive Breast Cancer.

To investigate the prognostic value of DGM-CM6 (Distant Genetic Model-Clinical variable Model 6) for endocrine-responsive breast cancer (ERBC) patients, we analyzed 752 operable breast cancer patients treated in a Taiwan cancer center from 2005 to 2014. Among them, 490 ERBC patients (identified by the PAM50 or immunohistochemistry method) were classified by DGM-CM6 into low- and high-risk groups (cutoff <33 and ≥33, respectively). Significant differences were observed between the DGM-CM6 low- and high-risk groups for 10-year distant recurrence-free survival (DRFS) in both lymph node (LN)- ( < 0.

PD-L1 expression level in different thymoma stages and thymic carcinoma: a meta-analysis.

Background: The immune checkpoint ligand, programmed cell death 1 ligand 1 (PD-L1), is expressed in various tumors and associated with response to drugs that target programmed cell death protein 1. Previous studies have estimated the level of PD-L1 expression among different stages of thymoma and thymic carcinoma to evaluate its potential use as a diagnostic factor; however, its varying expression level has been problematic. We conducted this meta-analysis of published literature to evaluate PD-L1 expression in thymomas and thymic carcinomas.
