My father in law was diagnosed with T Cell NH lymphoma in August 2016. He underwent 6 treatments of chop therapy. December 7 was his last therapy and he then had a clear PET scan January 8. January 16 he was re hospitalized with severe pain in the pancreas area. A biopsy of was done and sure enough it showed the lymphoma was back already. A ct scan was also done and it showed complete pleural effusion and the fluid in his lungs was almost completely filled and infected. The started him on lasix and it worked the first time. Second time around 3 days later it didn t work for 4 days and produced no urine. The kidneys are at 90% failed and he is on dialysis daily for the past 2 days. My questions is, can chemo be done during dialysis? He is 65 years old also.
