Case Reports
BRAF V600E-mutated lung adenocarcinoma with metastases to the brain responding to treatment with vemurafenib.
Somatic BRAF mutations have been reported in 1-4% of non-small cell lung cancer (NSCLC), primarily in adenocarcinomas with the BRAF (V600E) mutation in about 50% of the cases. The role of BRAF mutation in NSCLC and the treatment for tumors with such mutations is still evolving. ⋯ Our patient's visceral disease improved supporting vemurafenib's efficacy in the treatment of metastatic BRAF-mutated NSCLC. The regression of intracranial disease indicated vemurafenib was able to cross the blood-brain barrier and was efficacious in treating brain metastases in this patient with lung cancer.

Combined pulmonary fibrosis and emphysema (CPFE) patients may be at significantly increased risk of lung cancer compared with either isolated emphysema or pulmonary fibrosis patients. Acute exacerbation (AE) of interstitial lung disease caused by anticancer treatment is the most common lethal complication in Japanese lung cancer patients. Nevertheless, the clinical significance of CPFE compared with isolated idiopathic interstitial pneumonias (IIPs) in patients with lung cancer is not well understood. ⋯ CPFE was not an independent risk factor for AE and was not an independent prognosis factor in lung cancer patients with IIPs. Therefore, great care must be exercised with CPFE as well as IIP patients when performing anticancer treatment for patients with lung cancer.
