Nintedanib has been approved for the treatment of idiopathic pulmonary fibrosis (IPF). In addition, in EU countries, nintedanib plus docetaxel is used for patients with advanced non-small cell lung cancer (NSCLC) after first-line chemotherapy. Here, we report a case of advanced NSCLC in a patient with IPF successfully treated with nintedanib monotherapy. A 69-year-old man was diagnosed with NSCLC complicated by IPF. After three lines of chemotherapy, he still had progressive disease. Because his IPF had also progressed, requiring supplemental oxygen, we decided to start best supportive care and introduced nintedanib to treat his IPF. One month later, we observed a partial remission of the primary tumor and pleural disseminations without severe adverse events. Nintedanib monotherapy might therefore be an effective therapeutic choice for NSCLC in patients with IPF who are unable to tolerate cytotoxic chemotherapy.
Key points:• Efficacy of nintedanib administered in a NSCLC patient with IPF.• Nintedanib monotherapy might be a therapeutic option for NSCLC patients with IPF who are unable to tolerate chemotherapy.
Afatinib, a second-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) for mutant nonsmall cell lung cancer (NSCLC), was approved in Japan in 2014. This study evaluated clinical outcomes of afatinib in realworld practice. Medical records of patients who received afatinib for advanced EGFR-mutant NSCLC were retrospectively reviewed. In total, 128 patients were analyzed. Seventy-six patients received afatinib as the first-line setting and 52 as the re-challenge setting (i.e., after failure of prior first-generation TKI). There was no difference in patient characteristics, such as age, sex, and PS, between the first-line and the re-challenge settings. In the first-line setting, the median progression-free survival (PFS) was 17.8 months (95% confidence interval [CI] 13.7-21.5 months). The overall survival (OS) was 39.5 months (95% CI 34.4-not reached). The response rate (RR) was 64.4%. Subset analysis indicated that patients with dose reduction showed longer PFS than those without dose reduction (18.5 months versus 7.9 months) (P = 0.016). In the re-challenge setting, the median PFS was 8.0 months (95% CI 4.9-9.5 months). The RR was 25%. Most common adverse events leading to dose modification or treatment discontinuation included diarrhea, paronychia, and oral mucositis in both settings. Interstitial lung disease occurred in 5.4% (7/128). In the real-world practice in Japan, afatinib showed comparable or better efficacy compared with that shown in previous clinical trials in both the first-line and the re-challenge settings.
Pembrolizumab has become the standard first‐line treatment for non‐small cell lung cancer (NSCLC) patients with high PD‐L1expression. MET exon 14 skipping is a rare mutation typically found in older, female, and non‐smoking patients with NSCLC. Herein, we report the case of a 71‐year‐old non‐smoking woman who was diagnosed with NSCLC in the left lung. EGFR mutation and ALK fusion were not detected. Because the biopsy specimen showed high PD‐L1 expression with a tumor proportion score of 95%, pembrolizumab was introduced as first‐line therapy, but resulted in no clinical benefit. The patient was subsequently administered chemotherapy with carboplatin and pemetrexed, leading to remarkable tumor shrinkage. A next‐generation sequencing panel analysis revealed a MET exon 14 skipping mutation. Thus, pembrolizumab might not be effective for NSCLC patients with MET exon 14 skipping mutations, even if PD‐L1 expression is high.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
