Started on Padcef and Keytruda after chemo 18 months ago for stage 4 bladder cancer. Had 6 treatments with Padcef and stopped due to side effects. Normal is 7 treatments per my Doc and felt 6 was enough. Have been on Keytruda now for 18 months. Have had different side effect's but have been able to tolerate. CT PET scan per radiologist complete response to therapy.
