Barriers to obtaining gene expression profiling test heightened perceived value

Barriers to obtaining gene expression profiling tests heightened their perceived importance among patients with early breast cancer who were deciding whether to have chemotherapy, a new study says. Gene expression profiling tests, such as Oncotype Dx, analyze the patterns of 21 different genes within cancer cells to help predict how likely it is that a women's cancer will recur within 10 years after initial treatment and how beneficial chemotherapy will be to her.
