The symptoms of osteosarcoma metastasis, osteosarcoma most commonly metastasizes to the lungs. If pulmonary metastasis occurs, there are at least two prominent characteristics. The first is that most metastatic tumors are located on the surface of the lungs and are rarely within the lung parenchyma, thus, they are not difficult to detect.

The second point is that most metastatic tumors predominantly present as multiple bilateral lung metastases. Isolated unilateral lung metastasis is very rare. Therefore, this characteristic determines that osteosarcoma lung metastasis can only be managed with local wedge-shaped or segmental lung resections as the basic comfort measure. In fact, this simple surgical approach often allows for complete removal of the metastatic tumors while preserving most of the normal lung tissue.

Can osteosarcoma be treated with moxibustion?

Osteosarcoma is a malignant tumor of the bone, and the treatment effect of moxibustion is not very good. This disease develops quite rapidly, mostly occurring at the proximal end of the tibia, the distal end of the femur, the proximal end of the humerus, among others, typically at the metaphyseal ends. Clinically, the main symptoms include persistent pain, which becomes more pronounced at night, along with local swelling, restricted movement, increased local surface skin temperature, some may show prominent veins, and patients often appear emaciated, severely looking cachectic as the disease progresses with noticeable symptoms. Radiographic examination can reveal Codman's triangle or sunburst patterns. Early detection necessitates early treatment, including surgery such as inactivation reimplantation or prosthesis implantation to sustain operation. Additionally, amputation followed by extensive chemotherapy can effectively improve the patient’s survival time. Osteosarcoma has a high chance of early pulmonary metastasis, requiring systematic treatment at a hospital. Solely using moxibustion is not very effective and has limited usefulness, but it could still be worth a try if there are no better options available.

Can late-stage osteosarcoma be cured?

For osteosarcoma in its late stages, it often metastasizes to other organs, with the majority of cases involving lung metastasis. In such cases, conservative treatment can be applied. However, if surgery is an option, it is the best approach as it can be complemented with postoperative chemotherapy and radiotherapy to extend the patient’s survival time. If there is distant metastasis and the body is in poor condition, unable to withstand surgery, then only conservative treatment and nutritional support are viable, along with the use of painkillers. In late stages, when the patient cannot tolerate surgery, only conservative treatment is available with no other alternatives. Typically, the conditions are divided into three stages. By stage three, there is usually lung metastasis. This stage often involves T which signifies intracompartmental or extracompartmental growth—T2 indicating extracompartmental, typically a marker of an aggressive tumor. Then M represents metastasis, with 0 for none and 1 for presence. So, in cases where distant metastasis occurs, it generally corresponds to stage three, phase B, which involves extracompartmental invasive metastasis. In such cases, even surgery provides poor outcomes. Early detection and treatment are best. If it progresses to later or final stages, treatment is often deemed unnecessary, limited to conservative management, as surgical outcomes are poor, and metastasis may occur elsewhere.

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.

What are the symptoms of osteosarcoma?

Osteosarcoma is a very common malignant tumor, primarily occurring at the distal femur, proximal tibia, and proximal humerus. Its manifestations mainly include persistent pain at these three locations, which gradually worsens and is accompanied by nighttime pain. Secondly, there is local swelling; the surface of the tumor may feel warmer to the touch and may even exhibit prominent veins, leading to restricted joint movement near the tumor. Thirdly, some patients may exhibit signs of systemic deterioration, such as weight loss, anemia, and fatigue. Fourthly, osteolytic osteosarcomas often erode the bone cortex, eventually weakening the bone and leading to pathological fractures. Thus, the symptoms of osteosarcoma include persistent pain in specific areas accompanied by nighttime pain, local swelling, systemic deterioration, and pathological fractures in many patients.
