Cell counts provide a read on ovarian cancer

New technology might discern which tumors are most dangerous

A new test that tallies up useful immune cells in cancerous tissue could clarify a patient’s prognosis and possibly guide treatment, researchers say.

The technology counts helpful immune cells called tumor-infiltrating T lymphocytes. High counts of these cells in ovarian cancer patients have previously been associated with longer survival. But researchers at the Fred Hutchinson Cancer Research Center in Seattle note that existing technologies for measuring the tumor-attacking cells are cumbers...
