I was diagnosed with uterine carcinosarcoma in 2020 on my 70th birthday....and received a laparoscopic radical hysterectomy about 50 days after my bleeding had first started (during covid shutdown). Within a month after surgery I began to feel better than I had for several years and of course the bleeding stopped . The biopsy during surgery resulted in a stage 1 B. There had been more than 50% growth through the uterus wall but without observed spread to the 2 sentinel lymph nodes that were tested during the surgery. After surgery I was offered a chemo regimen and started a month or so later. Unfortunately the chemotherapy was too much for me, all the physical symptoms, weight loss, but also visual problems and illness. I gave up. I quit chemo after 4 of 6 treatments of the carbo-taxol and it was the best choice for me. Your grandmother of course will make her own choice. I do not think that I would have been able to physically survive a surgery after the chemotherapy. I felt relieved to learn that radiation is a option that she is considering. although I have no experience with that....its just that chemo was so debilitating. Like previous responders have said each patient is unique and by continuing to ask questions and seek information a way forward will be revealed. There was very little support available during covid. I am grateful that there are messages left by participants on this discussion site to help others embarking on similar journeys. It is good that you are there to help your grandmother wade through all the information and choices, and just for being there.
