Today, an international team led by scientists at UCSF released a new sturdy that can predict the likehood of death from early-stage lung cancer. These findings should help early-stage lung cancer patients decide on treatment options.
According to Bai He, a researcher who has worked on this project for over three years, the study includes two independent clinical trials, which involve the analysis of tissue samples from 433 patients in northern California, and another study with 1006 patients in China. All participants are early-stage lung cancer patients. The study finds that molecular tests can accurately predict the chance of death for patients.
The molecular test begins with a sample of the patienr’s cancerous tissue. Material known as RNA is then extracted from the tumors. The RNA reveals the relative activity levels of 14 genes within the tissues and those results are compared to levels in normal lungs. From here, doctors can distinguish which patients might need more treatment after surgery and which patients are at a low risk of death.
