Circulating tumour cells (CTCs) are reported to be predictive for prognosis and response to treatment in advanced lung cancer. However, the clinical utility of the CTCs detection remains unknown for early stage lung cancer as the number of CTCs is reported as low, providing challenges in identification. We have evaluated diagnostic performance of filtration-based technology using cytomorphologic criteria in patients undergoing surgery for lung cancer. ⋯ The performance of the tested filter-based antibody-independent technology to capture CTCs using standard cytomorphologic criteria provides the potential of a diagnostic blood test for lung cancer.

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.
