I Have Diffused Large B Cell NHL Lymphoma And Have

I have diffused large B Cell NHL Lymphoma and have gone through two programs at BCCA and over 620 hours of chemo without response. Mass in two areas-left auxiliary and above fatty part of kidney. Considering another clinical trial in Vancouver, however must be a point where I should strongly consider the US. Seattle = SCCA; Arizona = Mayo Clinic and Envita.

Any advice for me would be much appreciated!

Thank you
