Featured Science and Communiqués
DENVER – The combined use of fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC) identified non-small cell lung cancer (NSCLC) patients with rare or novel anaplastic lymphoma kinase (ALK) gene rearrangements, not otherwise identified by FISH alone, that showed response to crizotinib treatment.
DENVER – Analysis of a large non-small cell lung cancer (NSCLC) patient cohort with stage IV M1a disease identified lymph node staging as having clinical significance and an impact on prognosis.
Leptomeningeal Metastases Are More Common in NSCLC Patients Harboring EGFR Mutations and Respond Positively to TKI Therapy
DENVER – Leptomeningeal metastases (LM), a devastating complication and predictor of poor survival in lung cancer patients, was found to be more prevalent in non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutations. Patients receiving tyrosine kinase inhibitors (TKIs) targeting EGFR mutations had a longer overall survival (OS) than those who did not receive TKIs, demonstrating the effectiveness of TKIs for LM therapy.
Liquid Biopsies for the Identification of EGFR Mutations and for the Prediction of Lung Cancer Recurrence
DENVER – Three manuscripts published in the recent issue of the Journal of Thoracic Oncology, the official journal of the International Association for the Study of Lung Cancer (IASLC), explored the versatility of liquid biopsies by identifying EGFR mutations using circulating tumor DNA (ctDNA) in urine and plasma and examining circulating tumor cells (CTCs) in plasma to predict the risk of lung cancer recurrence after surgical resection. Collectively, these findings illustrate the potential and reach of liquid biopsies in both identifying patients suitable for targeted treatment as well as predicting cancer recurrence.
