Osteosarcoma is treatable, but it requires proper medical treatment. Currently, adjuvant chemotherapy significantly improves the five-year survival rate for osteosarcoma. The main treatment approach is still surgery as part of a comprehensive therapy. Specifically, the first step involves adequate preoperative chemotherapy, generally no fewer than six sessions over about eight weeks, or approximately two months. After this, patients often experience reduced pain, weight gain, improved positioning of the tumor, and a decrease in tumor size. Depending on the specific situation, a decision is made on the type of surgery to be performed—whether to amputate, preserve the limb, install a prosthetic, or use artificial bone as a replacement. Postoperative chemotherapy is usually also required to help ensure that the tumor does not recur and to increase the five-year or ten-year survival rate. Therefore, the current five-year survival rate for osteosarcoma has increased from the previous 40%-50% to about 80%. So, as long as one chooses the right hospital and the right treatment plan, and maintains confidence, osteosarcoma is usually treatable.
