The symptoms of recurrent osteosarcoma include the following points:

Firstly, if osteosarcoma recurs, it can cause sudden severe pain in the affected limb. This pain tends to intensify as the disease progresses and may shift from intermittent pain to continuous pain.

Secondly, there might be metastasis to the lungs or other parts of the body. In such cases, if lung metastasis occurs, the patient will experience significant chest tightness and breathing difficulties.

Thirdly, recurrent osteosarcoma can also lead to weight loss, decreased appetite, and the occurrence of low-grade fever.

Fourthly, if the tumor recurs, the patient’s joints and the affected limb's mobility will be significantly hindered, and this can also cause numbness in the affected limb.

Osteosarcoma is malignant.

Regarding whether osteosarcoma is benign or malignant, it is certain that osteosarcoma is a malignant tumor with a very high degree of malignancy. Once osteosarcoma is definitively diagnosed, aggressive treatment is necessary. Surgery is the main treatment approach, aiming to perform as extensive a resection as possible, or amputation may be required when necessary. After surgery, the resected specimen must be sent for pathological examination. Based on the type of pathology, the next step in treatment, either radiotherapy or chemotherapy, will be determined to minimize the recurrence of osteosarcoma, as a recurrence can endanger the patient's life.

How should osteosarcoma be treated?

Osteosarcoma is a malignant tumor that devours bone, commonly occurring in adolescents and young adults, typically at the proximal end of the tibia or the distal end of the femur, and at the proximal end of the humerus in the upper limbs, which is the metaphysis. The main clinical symptoms are pain, which becomes more pronounced at night, and there is generally a mass at the site, with limited movement. The local skin temperature may increase, and some may exhibit distended veins. Patients with malignant tumors generally gradually lose weight, eventually developing cachexia and even pathological fractures. Osteosarcoma is asymptomatic in its early stages, and once detected, it is usually in the middle to late stages. Radiographic examinations are necessary for diagnosis, typically showing specific changes such as Codman’s triangle or a sunburst pattern, which are characteristic of osteosarcoma. Surgery is necessary at times, to remove and examine the pathology. Common surgical approaches include resection with inactivation and reimplantation, or the insertion of a prosthesis for limb-sparing procedures, while another option is amputation, followed by extensive chemotherapy. With the rapid advancements in chemotherapy in recent years, the survival rate for osteosarcoma has generally increased significantly, typically about 50% over five years. However, early-stage pulmonary metastasis occurs very frequently with osteosarcoma, necessitating early diagnosis and treatment. The primary treatment is surgical, complemented by postoperative chemotherapy.

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.

What is osteosarcoma?

Firstly, osteosarcoma is a common type of malignant tumor, characterized by a mechanism that produces bone-like tissue. It has multiple subtypes and can also develop into a secondary osteosarcoma. Secondly, it commonly occurs in adolescents. Thirdly, it typically affects the proximal femur, distal tibia, and proximal humerus. Fourthly, common osteosarcomas are generally spindle-shaped, often located near joints. The surface may have elevated skin temperature and sometimes superficial vein distension is apparent. It often involves the entire bone, including the periosteum, cortical bone, and bone cavity. Generally, the tumor appears as a very fine greyish-white or brownish-red fish-flesh-like change. Osteosarcoma is a malignant tumor and is particularly prone to lung metastasis. According to tumor staging, it is at least stage IIB, indicating that it should be detected, diagnosed, and treated early. The earlier the treatment, the better the outcome and the higher the five-year survival rate.

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.)
