Gene expression helps classify cancers.
Only about 60 percent of people with diffuse large B-cell lymphoma diffuse large B-cell lymphoma Oncology A B-cell lymphoma that is the most common type–accounting for 30-40%–of NHL, which occurs in children and adults. See Lymphoma, Non-Hodgkin's lymphoma, WHO classification. , a common cancer of white blood cells White blood cells
A group of several cell types that occur in the bloodstream and are essential for a properly functioning immune system.

3. new tests that use so-called gene chips to look at the activity of thousands of genes simultaneously. Patients with one pattern of gene expression, called germinal-center B-like pattern, seem to respond better to treatment than the other patients do, says R. Eric Davis Eric Davis may refer to:
Among 19 people with germinal-center B-like disease, 14 were still alive 5 years after diagnosis, he and his colleagues report in the Feb. 3 NATURE. In contrast, only 3 of 19 patients with so-called activated B-like disease survived for 5 years.
The team hopes that gene chips will illuminate the cellular pathways that give rise to the slightly different cancers and those results will lead to more successful therapies.
