Background/aim: Amrubicin is recognized as a second-line treatment for refractory small-cell lung cancer (SCLC) and is administered immediately after chemotherapy; however, it has not been evaluated in patients with recurrent SCLC following chemoradiotherapy (CRT). This study aimed to examine the activity and safety of amrubicin monotherapy in patients with relapsed SCLC previously treated with CRT.
Patients And Methods: This retrospective study evaluated patients with relapsed SCLC who had been previously treated with CRT, followed by amrubicin monotherapy between April 2007 and June 2021.
Purpose: Nivolumab plus ipilimumab (Nivo-Ipi) combination therapy is an effective first-line treatment for advanced non-small cell lung cancer (NSCLC). However, its effectiveness and feasibility in elderly patients (aged ≥ 75 years) remain unclear. This study aimed to investigate the efficacy and safety of first-line Nivo-Ipi therapy in elderly patients with NSCLC.

This cancer primarily arises from mesothelial cells following exposure to carcinogenic, biopersistent mineral fibers, particularly asbestos. The histological subtypes of mesothelioma are epithelioid (approximately 60%), sarcomatoid (20%), and biphasic (20%), exhibiting epithelioid and sarcomatoid characteristics.

A 78-year-old female with lung adenocarcinoma presented with neurological symptoms and was diagnosed with a brain abscess. During treatment, she developed heart failure and encephalopathy, linked to osimertinib and metronidazole, respectively.

Methods: Eighty patients diagnosed with PM between June 2007 and August 2022, were eligible for this study.
Background: The standard treatment for patients in good general condition with limited-disease small cell lung cancer (LD-SCLC) is concurrent platinum/etoposide chemotherapy and thoracic radiotherapy (TRT). However, the efficacy and safety of chemoradiotherapy (CRT) in older patients with LD-SCLC has not been fully explored; moreover, the optimal treatment for this patient group remains unclear. This study aimed to investigate the feasibility and efficacy of CRT in older patients with LD-SCLC.

Case Report: A 66-year-old female was definitively diagnosed with G-CSF-producing lung cancer that was positive for EGFR mutations. She repeatedly received epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), such as osimertinib and afatinib.
Selpercatinib, a tyrosine kinase inhibitor approved for RET-fusion gene-positive lung cancer, can induce hypersensitivity, potentially exacerbated by prior immune checkpoint inhibitor (ICI) therapy. We present a case of severe toxicity following selpercatinib treatment in a 58-year-old female with lung adenocarcinoma, refractory to previous treatments including pembrolizumab. Symptoms included fever, rash, and multiorgan failure indicative of grade 4 hypersensitivity.

Little is known about the mechanisms underlying SR; however, immunological reactions, infections, injuries, and medications have been presumed. Among previously reported cases of SR, lung cancer cases have been extremely limited.

The mechanism of cancer-associated MN is presumed to involve the immunological production of antibodies against a tumor antigen, although little is known about the detailed mechanism. Lung cancer is a major neoplasm associated with cancer-associated MN.
