Are osteosarcomas sensitive to radiotherapy and chemotherapy?
Osteosarcoma is generally insensitive to radiotherapy, hence radiation therapy is not used for such diseases in clinical settings. Similarly, these diseases have a moderate sensitivity to chemotherapy, necessitating the use of relatively high doses of chemotherapy during treatment. The main mechanism of chemotherapy involves using a series of cytotoxic drugs to inhibit tumor growth. Although high-dose chemotherapy can effectively kill tumor cells, it can also damage some of the patient's normal cells, leading to severe reactions. If radical surgery is viable for these patients, then curative surgery is the preferred method of treatment.
The difference between rib flare and pigeon chest
The main difference between rib flaring and pigeon chest is that the former is caused by soft tissue pathology around the thoracic cage, while the latter is due to a bony deformity of the thoracic cage. Patients with rib flaring often have very thin muscles around the thoracic cage due to poor posture, such as excessive abdominal tucking or long-term dieting, which leads to a very prominent thoracic cage when standing. Pigeon chest, on the other hand, is due to severe malnutrition during the patient's growth and development phase, which leads to the anteroposterior diameter of the thoracic cage being larger relative to the mediolateral diameter. In this case, the patient will exhibit a noticeably protruding thoracic cage, especially at the front.
