Hello, I'm new to this group and wanted to find answers to concerned questions. My partner had been diagnosed with Mantel Cell Lymphoma three years ago. He underwent Chemo and stem cell treatment. Recently after a routine blood test, the doctors said his WBC was rising rapidly it's doubled in the last two week to 80% above average. His platelet count has also started to drop. He looks and feels great, has been putting on weight and is not experiencing any symptoms he had when he was first diagnosed (sweats, fatigue, gaunt look). His doctors said they want to put him on Ibrutinib straight away before he starts to feel unwell. He had a Scan and we're waiting for the results, but the doctors that doesn't matter anyway because his platelets are dropping. Has anybody had experience with Ibrutinib and what are the side effects. I understand they are different for everybody. I just wanted to know of other people experience with Ibrutinib - good and bad!
