Abstract

V-raf murine sarcoma viral oncogene homologue B1 (BRAF) is a proto-oncogene that regulates cell proliferation and survival. BRAF V600E-mutated lung cancer has aggressive characteristics and is resistant to chemotherapies. Combination of BRAF-specific inhibitor dabrafenib and mitogen-activated protein kinase kinase (MEK) inhibitor trametinib is the standard treatment for BRAF V600E-mutated lung cancer. We report a case of BRAF V600E-mutated lung adenocarcinoma, which presented with respiratory distress due to deterioration of advanced cancer. The tumour responded rapidly and significantly to BRAF/MEK inhibitors, and the patient's symptoms improved within 2 weeks. BRAF/MEK inhibitors are effective treatment in BRAF-mutated lung cancer even under critical conditions.

摘要

V-raf鼠肉瘤病毒癌基因同源物B1(BRAF)是一种调节细胞增殖和存活的原癌基因。BRAF V600E突变型肺癌具有侵袭性特征,并且对化疗耐药。BRAF特异性抑制剂达拉非尼和丝裂原活化蛋白激酶激酶(MEK)抑制剂曲美替尼联合使用是BRAF V600E突变型肺癌的标准治疗方法。我们报告了一例BRAF V600E突变型肺腺癌病例,该病例因晚期癌症病情恶化出现呼吸窘迫。肿瘤对BRAF/MEK抑制剂迅速且显著地产生反应,患者症状在2周内得到改善。即使在危急情况下,BRAF/MEK抑制剂对BRAF突变型肺癌也是有效的治疗方法。
