My Mom had a single Plasmacytoma in her thoracic spine in 2011 and was treated with radiation. She has been in remission until this week when her oncologist found 2 tumors or places of malignancy on her hip and her ribs. Mom is almost 85 and when she told her oncologist she did not want chemotherapy the oncologist suggested we get Hospice on board. Not sure what her blood work showed but can I assume from the Hospice suggestion that she has less than 1 yr to live w/out Chemotherapy?
Thanks for your question on Chat Doctor. Plasmacytoma is highly aggressive bone malignancy.  It can rapidly spread in other bones and distal organs. And it is highly responsive to chemotherapy and radiotherapy. Usual life expectancy with chemo and radiotherapy is up to 1 year. But in your mothers' case as tumor had spread in hip bone and in ribs, plus she denied further treatment, prognosis is not good. Life expectancy will be less than 6-7 months in your mothers case. Better to discuss end of life issues and give palliative treatment for bone cancer.
