Clinical efficacy of amrubicin in patients with small cell lung cancer relapse after first-line treatment including immune checkpoint inhibitors: A retrospective multicenter study (TOPGAN 2021-01).

Background: The therapeutic efficacy of cytotoxic anticancer drugs has been reported to be enhanced after immune checkpoint inhibitors (ICI) in non-small cell lung cancer; however, it is unclear whether the same is applicable for small cell lung cancer (SCLC). We evaluated the efficacy of second-line amrubicin (AMR) following first-line platinum-based chemotherapy and ICI combination therapy (chemo-ICI) in SCLC.

Patients And Methods: We retrospectively enrolled consecutive patients with SCLC treated with AMR as a second-line following chemo-ICI as first-line between July 2019 and April 2021 from 16 institutions throughout Japan.

Phase I/II study of nedaplatin and nab-paclitaxel for patients with previously untreated advanced squamous cell lung cancer: Kanto Respiratory Disease Study Group (KRSG) 1302.

Background: Nedaplatin and nab-paclitaxel are each efficacious in the treatment of squamous cell lung cancer.

Patients And Methods: Eligibility criteria were: no prior chemotherapy, advanced squamous cell lung cancer; performance status 0-1, age > 20 years but < 75 years, and adequate hematologic, hepatic and renal function. Patients received escalating doses of nab-paclitaxel under a fixed dose of nedaplatin (100 mg/m, day 1) every 3 weeks in phase I.

Clinical efficacy of dacomitinib in rechallenge setting for patients with epidermal growth factor receptor mutant non-small cell lung cancer: A multicenter retrospective analysis (TOPGAN2020-02).

Background: Dacomitinib is the second-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) for mutant non-small cell lung cancer (NSCLC). EGFR-TKIs are often re-administered in Japan after the disease progression prior EGFR-TKI. There is little evidence of dacomitinib in rechallenge setting.

Immunoglobulin G4-related Pleuritis Complicated with Minimal Change Disease.

A 70-year-old woman with bilateral pleural effusion and respiratory failure was admitted to our hospital. Nephrotic syndrome due to minimal change disease had been diagnosed four months before admission. Because blood tests and a pleural fluid analysis did not reveal the etiology of her condition, we performed a video-assisted thoracoscopic pleural biopsy.

Dramatic response to alectinib in a patient with ALK-rearranged squamous cell lung cancer.

Lung cancers with anaplastic lymphoma kinase (ALK) rearrangements are highly sensitive to treatment with ALK tyrosine kinase inhibitors (TKIs). Due to the very low rate of patients with squamous cell carcinoma enrolled in clinical trials, the efficacy of ALK inhibitors in patients with ALK-rearranged squamous cell carcinoma in the lung remains unclear. Herein, we present the case of a 70-year-old female patient with squamous cell lung cancer harboring the echinoderm microtubule-associated protein-like 4 (EML4)-ALK fusion gene.
