How about both at same time?In late May I started Radiation to my neck(20 Treatments)after 2 ipi doses because Ipi caused massive swelling of neck nodes that were threatening my airway and esophagus and carotid artery.I finished Ipi and radiation about the same time. A Pet Scan at 4 wks showed mixed response. No nodes in neck lit up but there was 5 new areas of concern in my Rt Pelvis that were new. I hadn’t been scanned since March so we are hoping they were there before I started Ipi and actually were smaller. Will find out tomorrow with Pet scan. A right axillary node and rt groin node are barely palpable so either ipi or abscopal effect. Keeping my fingers crossed!
