Hi, Dear,Good evening from INDIA. Thanks for the query to Chat Doctor. I studied your query in details and understood your concerns.@My impression of your case -is-mostly -Primary Malignant Fibrous Histio-cytoma which was followed after lymph(Malignant Fibrous Histio-Cytoma) with spine metastasis.-Prognosis of such tumors -which are secondary to primary femur tumors very bad. Suggested Treatment-a-Chemotherapy to reduce the mass load by Intra-Arterial Selective treatment would reduce the toxic effects and better tumor response. This treatment needs to be taken with- ONCO-Surgeon-Physician / and orthopedic Surgeon.@Hope this would resolve your worrisome query. Welcome for any further query in this regard, and would love to help you to resolve this problem till it is solved to your satisfaction.@I would take opportunity to request you to Write strong recommendations promoting my services for the benefit of my new and old patients at Chat Doctor clinic.
