TDM1 and lymphocytes( T cells)
Hi ,

I know this is highly technical but anybody know if TDM1 damages the lymhocytes or T cells. I know it lowers platelets.

Thanks,
Julie

Re: TDM1 and lymphocytes( T cells)
Julie,

According to this report, the side effect of TDM-1 is very, very small compared to the traditional ways of giving Herceptin. I think that's the purpose of TDM-1 - that it will go straight to the cancer cells and destroy them...

No I don't have any problem with T cells. But, I do have low potassium and low heart fracture.
