Mesenchymal-epithelial transition factor (MET) amplification is an important driver of resistance in epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC), and the combination of MET proto-oncogene (MET) and EGFR-tyrosine kinase inhibitors (TKIs) has shown promise in overcoming this molecularly defined acquired resistance. Emerging data also demonstrate MET amplification as a resistance driver to TKIs-treated anaplastic lymphoma kinase (ALK)-, RET-, and ROS1-fusion NSCLC. Here, we review the literature on recent research progress of MET amplification as a resistance driver to targeted therapy in oncogene-driven NSCLC and summarize the progress of clinical strategies to overcome the resistance mechanism. .

Background: Early diagnosis of systemic light-chain amyloidosis (AL) is needed because 25% of patients die within months of diagnosis. In patients with monoclonal gammopathy of undetermined significance (MGUS) or smoldering multiple myeloma (SMM) of the λ isotype, we explored the use of 2 screening variables: a free light chain difference of 23mg/L between λ and k and presence of IGLV genes that occur more frequently in AL.
Methods: Patients contacted us and we sent HIPAA release and consent forms for discussion by phone.

The impact of clinical stage on the effectiveness of osimertinib for epidermal growth factor receptor (EGFR) mutation-positive non-small cell lung cancer (NSCLC) remains unexamined. We investigated osimertinib therapeutic efficacy variation between stage IVA or lower and stage IVB EGFR mutation-positive lung cancers, focusing on differences in pretreatment co-occurring genetic alterations in circulating tumor DNA. This was a secondary analysis of the ELUCIDATOR study, a multicenter prospective observational study in Japan that assessed the mechanisms underlying resistance to osimertinib as a first-line treatment for advanced NSCLC with EGFR mutations.

Objective: This study assessed the impact of intrathecal pemetrexed (IP) in managing leptomeningeal metastases (LM) in previously treated patients with -mutant advanced non-small cell lung cancer (NSCLC).
Methods: We analyzed the clinical and survival outcomes of 50 patients with LM who received 50 mg IP after disease progression with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) treatment between September 2021 and September 2023 at the Hunan Cancer Hospital. Treatment response was evaluated based on improvement in neurological symptoms/signs and Karnofsky Performance Status (KPS) scores.

EGFR tyrosine kinase inhibitors (TKIs) have significantly improved clinical outcomes for patients with non-small cell lung cancer (NSCLC) harboring EGFR-activating mutations. However, resistance to TKI therapy often develops due to secondary EGFR mutations or the activation of bypass signalling pathways. Next-generation sequencing (NGS) can efficiently identify actionable genetic alterations throughout treatment.

Aims: Endometrial cancer (EC) is the most common gynecological cancer worldwide and its incidence is rising. The cornerstone of its management is surgical treatment with nodal staging. A monocentric study investigating the potential of the molecular biology method of one-step nucleic acid amplification (OSNA) in sentinel lymph node (SLN) analysis was conducted at our institution between April 2016 and January 2018.
