BRAF mutant PD-L1 positive metastatic musculoskeletal lesions from primary lung adenocarcinoma treated with combination vemurafenib and pembrolizumab: a case report.
Background: B-Raf mutation positivity, B-Raf mutation positivity occurrence with programmed death ligand 1 overexpression, and musculoskeletal metastasis are singly rare in non-small cell lung cancer, and even rarer is all occurring in one patient.
Case presentation: A Filipino 63-year-old male had B-Raf mutation positive and programmed death ligand 1 overexpressed symptomatic metastatic musculoskeletal lesions from lung adenocarcinoma treated with a BRAF inhibitor, vemurafenib, in combination with an immune checkpoint inhibitor, pembrolizumab. He exhibited significant reduction in pain and burden of musculoskeletal metastatic lesions.
Conclusion: Although a rare occurrence and known to have a poor prognosis, B-Raf mutation positive programmed death ligand 1 overexpressed lung adenocarcinoma presenting with metastatic musculoskeletal lesions can respond favorably to a combination immune checkpoint inhibitor and BRAF inhibitor medication.
期刊介绍：
JMCR is an open access, peer-reviewed online journal that will consider any original case report that expands the field of general medical knowledge. Reports should show one of the following: 1. Unreported or unusual side effects or adverse interactions involving medications 2. Unexpected or unusual presentations of a disease 3. New associations or variations in disease processes 4. Presentations, diagnoses and/or management of new and emerging diseases 5. An unexpected association between diseases or symptoms 6. An unexpected event in the course of observing or treating a patient 7. Findings that shed new light on the possible pathogenesis of a disease or an adverse effect
