Do osteosarcomas require amputation? In the past, the likelihood of amputation for treating osteosarcoma was very high. However, currently, the rate of amputation is very low, and the limb-salvage rate is very high. This is due to a new chemotherapy protocol in medical practice, which involves initial chemotherapy followed by surgery, and then continued chemotherapy post-operatively. The limb-salvage rate with this treatment plan can reach about 75% to 80%. Therefore, currently, most osteosarcoma patients do not require amputation. Unlike the past, where amputation rates were very high, today's medical approach is very advanced, generally resulting in a very high rate of limb preservation for osteosarcoma patients.

Why is there a cough in osteosarcoma?

Osteosarcoma ranks second in the incidence of malignant tumors in the whole body's bones; its incidence is relatively high. It generally occurs in the long tubular bones, shafts, or epiphyseal areas of the limbs. Since the most common organ metastasis of osteosarcoma is to the lungs, if a patient with osteosarcoma develops a cough, it should be taken seriously, and it's recommended that the patient undergo a targeted examination such as a chest X-ray or a CT scan of the lungs to check for lung metastasis and any lesions on the lungs. However, there is no need to panic prematurely, as osteosarcoma patients might cough due to upper respiratory infections or lung infections, which doesn't necessarily indicate lung metastasis. Therefore, once a patient with osteosarcoma develops a cough, a targeted examination should suffice.

Is chondrosarcoma cancer?

Chondrosarcoma is broadly cancer, but in medical terms, we wouldn’t necessarily phrase it that way; we simply describe chondrosarcoma as a type of malignant tumor, and currently, its treatment outcomes are not very good. Generally, when we talk about cancer, we’re referring to malignant tumors that originate from epithelial tissue, including cancers like stomach cancer, lung cancer, colon cancer, and liver cancer, which all derive from epithelial tissues. However, because chondrosarcoma originates from mesenchymal tissue, which includes muscle, cartilage, blood vessels, and nerves, malignant tumors that occur in these areas are usually called sarcomas. Sarcomas are definitely malignant, but to strictly call them cancer is not particularly precise.

Will osteosarcoma cause the skin to turn red?

Patients with osteosarcoma will not have red skin. The early symptoms of osteosarcoma are generally not obvious, primarily involving localized swelling, with pain around the joints leading to limited joint mobility. As the condition progresses, this pain may shift from intermittent to constant, and the severity of the pain will increase as the disease worsens. The second patient will exhibit a noticeable lump that can be felt; this lump is usually accompanied by significant tenderness. The third symptom is intermittent limping, caused by pain from the tumor during walking, which prevents the patient from bearing weight for extended periods. The fourth aspect involves systemic symptoms common to patients with tumors, such as anemia, mild fever, and even pathological fractures.

How to alleviate the pain of osteosarcoma?

Pain in osteosarcoma patients is mostly caused by the cancer invading local bone tissue and other tissues, leading to pain, tenderness, and even sleeplessness. Therefore, the pain management follows a certain hierarchy, starting with non-steroidal anti-inflammatory drugs, followed by weak opioids, and finally strong opioids such as morphine. However, this only alleviates the pain and does not help with treatment. For early-stage osteosarcoma patients, pain management primarily involves surgery when necessary. For advanced-stage patients, it involves gradually increasing the dose of effective pain-relief medications to alleviate temporary pain. (Controlled drugs must be strictly used under the supervision of relevant physicians.)

Causes of Osteosarcoma Formation

The causes of osteosarcoma formation are currently unclear in clinical practice, but they are somewhat related to environmental factors and genetic changes, including heredity. If triggered by external viral infections or physical and chemical influences, osteosarcomas may develop. Likewise, genetic mutations and cellular mutations might also be associated with the formation of osteosarcomas. Osteosarcomas originate from mesenchymal cells and can grow rapidly; passing through a cartilaginous stage, they directly and indirectly form bone-like and bone tissues, damaging the bone structure, which leads to severe consequences.
