Consensus on the lung cancer management after third-generation EGFR-TKI resistance.

Lung cancer is the most prevalent malignant tumour in the Asia-Pacific region. Non-small cell lung cancer (NSCLC) accounts for approximately 85% of lung cancers. Among these, the rate of mutations in Asian patients with lung adenocarcinoma is 40-60%.

Real-world status of multimodal treatment of Stage IIIA-N2 non-small cell lung cancer in Japan: Results from the SOLUTION study, a non-interventional, multicenter cohort study.

Objectives: There is limited consensus on resectability criteria for Stage IIIA-N2 non-small cell lung cancer (NSCLC). We examined the patient characteristics, N2 status, treatment decisions, and clinical outcomes according to the treatment modality for Stage IIIA-N2 NSCLC in Japan.

Materials And Methods: Patients with Stage IIIA-N2 NSCLC in Japan were consecutively registered in the SOLUTION study between 2013 and 2014.

Postoperative adjuvant therapy with molecularly targeted agents for non-small cell lung cancer.

The efficacy of molecularly targeted agents has been established in advanced lung cancer, and their indications have recently expanded to include perioperative treatment of resectable lung cancer. For epidermal growth factor receptor (EGFR) mutation-positive patients, postoperative adjuvant therapy with EGFR-tyrosine kinase inhibitors (EGFR-TKIs) is available in Japan following the results of the ADAURA trial. In addition to EGFR-TKIs, postoperative adjuvant therapy with TKIs targeting anaplastic lymphoma kinase (ALK) and rearranged during transfection (RET) is expected to be established.

Spatially resolved gene expression profiling of tumor microenvironment reveals key steps of lung adenocarcinoma development.

The interaction of tumor cells and their microenvironment is thought to be a key factor in tumor development. We present spatial RNA profiles obtained from 30 lung adenocarcinoma patients at the non-invasive and later invasive stages. We use spatial transcriptome sequencing data in conjunction with in situ RNA profiling to conduct higher resolution analyses.
