Targeted therapy of lung cancer refers to using agents specifically designed to selectively target molecular pathways responsible for, or that substantially drive, the malignant phenotype of lung cancer cells, and as a consequence of this (relative) selectivity, cause fewer toxic effects on normal cells.
In recent years, various molecular targeted therapies have been developed for the treatment of advanced lung cancer. Gefitinib (Iressa; withdrawn from the U.S. market) is one such drug, which targets the tyrosine kinase domain of the epidermal growth factor receptor (EGFR), expressed in many cases of non-small cell lung carcinoma.
There are targeted therapies for lung cancer, colorectal cancer, head and neck cancer, breast cancer, multiple myeloma, lymphoma, prostate cancer, melanoma and other cancers. [1] [4] [5] Biomarkers are usually required to aid the selection of patients who will likely respond to a given targeted therapy. [6]
Lilly's drug, now called selpercatinib, is intended for patients with rare RET abnormalities, which occur in about 2% of non-small cell lung cancers, some 10 to 20% of papillary thyroid cancers ...
Lung cancer is the most diagnosed and deadliest cancer worldwide, with 2.2 million cases in 2020 resulting in 1.8 million deaths. [3] Lung cancer is rare in those younger than 40; the average age at diagnosis is 70 years, and the average age at death 72. [2] Incidence and outcomes vary widely across the world, depending on patterns of tobacco use.
Current treatments include surgery, chemotherapy, radiation and targeted therapy for those who have a cancer with a biomarker. Doctors have good success in treating early-stage lung cancer, so ...
