Promising Effect of Crizotinib on Anaplastic Lymphoma Kinase (ALK)-Positive Non-Small Cell Lung Cancer in an Elderly Patient with a Poor Performance Status: A Case Report and Literature Review
Аннотация:Crizotinib is highly effective for anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC). However, it remains unclear whether crizotinib has a beneficial effect on elderly patients with ALK-positive NSCLC with a poor performance status (PS). We herein present the case of an 85-year-old man with stage IV ALK-positive NSCLC, whose PS score was 4 due to pericardial and pleural effusions. After initiating crizotinib therapy, a drastic response was observed and the PS score improved to 0. Adverse effects were manageable. Our results indicate that crizotinib could be an important choice when treating elderly patients with ALK-positive NSCLC with poor PS.
