Chronic Lymphocytic Leukemia: Study of green tea extract inconclusive

I just want to tell my story about CLL. I was diagnosed in December 2012 with it and my son found your report on a study you had done with EGCG and Vitamin D3. I printed it out and read it and started on those 2 things immediately. I've been taking them every since and I haven't had to be treated for CLL yet. I see my cancer doctor twice a year and have blood tests twice a year and while my white cell count is high, I haven't had to be treated for CLL yet. I'm so thankful for your study and that my son found it and told me about it. I am 76 years old and have had over 8 more years than I thought I would when I was diagnosed and I think you should broadcast to the world about that study. I realize not everyone will respond the way I have but you could be saving lots of lives and helping lots of others to find a way to help themselves. Thank you so much for your studies.

UPDATE FROM THE COMMUNITY DIRECTOR
Mayo Clinic cannot recommend that EGCG be used by CLL patients. Green tea trials haven't been conclusive, and this subject requires more study before doctors can agree on the merits of this treatment.

"From the reported data, our current recommendation is to avoid green tea, both as EGCG and as an extract, usage by CLL patients, especially those with any history of liver or gastrointestinal disease or receiving CLL-directed therapy. The current research for green tea in CLL has demonstrated minimal activity in terms of objective responses, mostly in asymptomatic, early-stage patients who would not normally warrant CLL-directed therapy by the International working group CLL criteria.44 In addition, the current data support the occurrence of significant adverse events (even with limited exposure) associated with green tea, especially its extracts and EGCG. This is especially concerning when most patients who consume green tea extracts/EGCG are asymptomatic from the perspective of their underlying disease. At present, we could not identify ongoing trials for green tea or green tea extract in CLL patients."
