Hello All. Things were going remarkably well for my mo. Radiisurgery was very effective, lung tumor had zero growth over two months and she tolerated her first Keytruda treatment well. Then she was hit with Pneumonia and subsequently dx with COPD. The pulmonologist is suggesting large daily doses of steroids to treat which will of course eliminate the use of Keytruda. We want to avoid this. She’s in great spirits and looks and feels well except that she’s on 5L of oxygen and they can’t get her pulse ox above 89-90. Has anyone been through this? Can we avoid steroids for her? Thanks in advance.
