LOS ANGELES (Reuters) – Testing lung cancer patients for tumor markers would enable doctors to choose which drug the patient is most likely to respond to, improving the chances for successful treatment, according to results from a recent trial.

The mid-stage study, conducted at the University of Texas M.D. Anderson Cancer Center in Houston and funded by the U.S. Army, enrolled 255 patients with advanced lung cancer who had previously been treated with chemotherapy.

“We are still in the dark ages with how we treat lung cancer patients,” said Dr. Edwin Kim, associate professor at the center’s thoracic/head and neck oncology department and the study’s lead investigator. Currently, they are separated only into “histologic” categories such as small cell or non-small cell lung cancer, with subtypes like squamous or non-squamous.

“As far as molecular testing nothing is standardly done in lung cancer at this time,” Kim said.

For other types of cancer — such as breast and colon — such testing has become common in recent years amid the development of biologic drugs designed to work only against tumors with specific genetic or molecular characteristics.

Patients in the MD Anderson trial had their lung tumors biopsied and tested for several “biomarkers” including epidermal growth factor receptor, or EGFR; vascular endothelial growth factor, or VEGF; a gene known as KRAS; and another that encodes for a protein called Cyclin D1.

Erlotinib, sold by Roche Holding AG and OSI Pharmaceuticals Inc under the brand name Tarceva, is designed to block EGFR, a protein found in high amounts on many types of cancer cells…. (more…)
