The PET showed no change from before BEACOPP and after ABVD. That means the chest tumor seems to still be alive. There is a chance the PET is wrong so a biopsy is being planned. This takes special surgical skill given the location. Timing tbd. If it still is alive a new chemo regimen specific for Hodgkins will start. This is outpatient every 3 weeks for 4 times with a PET in the middle. We need to stay focused on the cure! The timeline changed but nothing more.
