Hi. I was diagnosed B-PLL at the end of 2017. I didn't find any discussion groups for it so I've been hanging out reading HealthUnlocked CLL forum and feeling like I didn't belong in any cancer forums out there. I have 17 deleted and P53 issue also. I'm on imbruvica they say for the rest of my life (or until the imbruvica fails). I was just surfing internet for the mouse study re fasting leptin leukemia then looking at B-lymphocytes info and there you were in my search results somehow ! So hello from another person in this lonely B-PLL club
