Abstract | PURPOSE: METHODS: A total of 77 patients who received topotecan for the treatment of relapsed SCLC between April 2007 and April 2014 were reviewed. Patients with pre-existing ILD were identified using the pretreatment chest computed tomography. The safety of intravenous topotecan for SCLC patients with ILD was retrospectively examined, particularly focusing on topotecan-induced acute exacerbation of ILD (AE-ILD). RESULTS: Twenty-three patients were identified as having pre-existing ILD [median age 74 (range 55-85) years; 21 men]. At the first topotecan administration, two-thirds (65.2%) had an Eastern Cooperative Oncology Group performance status 0 or 1. Topotecan was administered intravenously as second-line (n = 11) or later chemotherapy (n = 12). The median number of treatment cycles was two (range 1-7). The most common adverse events with grade 3 or 4 were neutropenia in 13 patients (56.5%) and thrombocytopenia in 10 patients (43.5%). Febrile neutropenia was observed in six patients (26.1%) and resulted in one death. AE-ILD occurred in five patients (21.7%; 95% confidence interval 4.9-38.5 %) 5-18 days after the last administration of topotecan and was fatal in three cases. CONCLUSIONS: Intravenous topotecan monotherapy can be unsafe for relapsed SCLC patients with pre-existing ILD. Clinicians should be cautious regarding topotecan-induced AE-ILD as a lethal complication.
