###Human: What can be done for osteogenic sarcoma? ###Assistant: Hi. I have gone through the reports of your sister (attachment removed to protect patient identity). It looks she has osteosarcoma, a type of bone cancer. In the pathology report, they have not mentioned which subtype osteosarcoma and the grade of this sarcoma (high or low). Now she must do a CT scan chest to check for any spread to the lungs. If the lungs are free then it is a localized disease. Usually, for localized osteosarcoma, she may need chemotherapy followed by surgery (limb-sparing surgery if feasible) and then again chemotherapy. It is difficult to comment (step-wise treatment) without seeing and examining the patient physically.
