"The results showed that EGCG inhibited the proliferation of AML cells in all cases examined."
"We also found that EGCG inhibited the modulation of c-kit, a receptor for stem cell factor, on leukemic cells. These findings suggested that EGCG might be available as a new therapeutic tool for AML patients."

"A green tea extract has shown some promise in initial clinical trials for treating chronic lymphocytic leukemia. Laboratory research determined that a compound in green tea extract, called EGCG, can kill chronic lymphocytic leukemia cells. A study of people with early-stage chronic lymphocytic leukemia found that EGCG in pill form reduced some signs of the disease. But green tea trials haven't been conclusive, and this subject requires more study before doctors can agree on the merits of this treatment."
