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.

Osteosarcoma diagnostic methods

Osteosarcoma Diagnostic Methods: In clinical practice, once osteosarcoma is suspected in a patient, the diagnostic approach, as per the Chinese Cancer Treatment Guidelines, requires a combination of clinical symptoms, radiological data, and pathology. Only through the integration of these three elements can a definitive diagnosis of osteosarcoma be established. Reliance solely on pathology, or exclusively on radiologic examination or clinical examination, can lead to biased results. Given that immediate treatment is crucial upon the discovery of osteosarcoma, and considering the severe implications of treatment costs, patient suffering, and other related issues, it is vital that the diagnosis of osteosarcoma is error-free. To ensure absolute certainty, the approach should involve clinical symptoms supplemented by necessary auxiliary examinations such as X-rays and CT or MRI scans, followed by a diagnostic biopsy for pathological results. This comprehensive combination generally prevents the occurrence of missed or misdiagnoses in patients with osteosarcoma. Therefore, the confirmatory diagnosis of osteosarcoma should not rely solely on one type of examination but should combine clinical assessment with necessary imaging data and pathology to finalize the diagnosis process.

Is osteosarcoma serious?

Osteosarcoma is a fairly serious condition. It is a type of malignant bone tumor and is classified as stage II according to the Eric staging system. Regardless of the treatment method used for osteosarcoma, the first issue is that it metastasizes quickly, and the second is that it tends to recur frequently. Therefore, once someone has osteosarcoma, it poses significant challenges, not only being difficult to treat but also involving considerable treatment costs. However, thanks to the efforts of researchers, a new adjuvant chemotherapy has been developed which has increased the five-year survival rate of osteosarcoma from 47% to about 80%, which is quite remarkable. Moreover, with this new adjuvant chemotherapy, patients first undergo chemotherapy, followed by surgery, during which chemotherapy is administered again, not only improving the five-year survival rate but also enhancing the quality of life for patients. Therefore, osteosarcoma is a very serious disease. In the past, amputation was common, followed by distal metastasis, so it didn't take long for metastases to appear in the lungs or brain. Thus, osteosarcoma is an extremely serious disease.

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.

Osteosarcoma mainly metastasizes through

The main metastatic pathways of osteosarcoma are generally divided into three types. The first is hematogenous spread, which refers to the dispersal of tumor cells throughout the body via the bloodstream, typically settling in areas with slower blood flow which facilitates the deposition of these cells leading to local changes. The second is direct implantation, which involves tumor cells directly establishing themselves in the vicinity of the tumor's common sites, eventually leading to local metastasis. The third type is lymphatic spread, where tumor cells migrate through the lymphatic system, spreading along lymphatic vessels or pathways. Therefore, the main metastatic pathways of osteosarcoma are these three types. The primary sites of metastasis for osteosarcoma are mainly the lungs, but metastases can also occur in the brain or through other mechanisms.

Does osteosarcoma hurt when pressed?

Osteosarcoma, also known as osteogenic sarcoma, is a primary malignant tumor of the bone. It ranks second in incidence among bone tumors and has a relatively high incidence and malignancy rate. It is more common in adolescents and occurs more frequently in males than in females. The earliest clinical symptoms of this disease include dull pain and persistent pain that worsens with activity, as well as nighttime pain, which is more pronounced than daytime pain. This is a very important characteristic, indicating that patients experience nighttime pain and rest pain. The affected area may develop a rapidly growing mass that changes significantly in size from month to month. If the tumor grows large, pressing on it can cause pain, but in the early stages when the tumor is not very large, the tenderness may not be very apparent, presenting only as localized spontaneous pain, which requires attention.
