What Is A Sarcoma

Sarcomas Malignant tumors of mesenchymal tissue (including connective tissue and muscle) are called sarcomas. It can occur in all parts of the body, often in the deep parts of the limb, such as the subcutaneous, periosteum and long bone ends. For example, osteosarcoma is mostly young people, and it is easy to occur in the limbs. It develops rapidly with a short course of disease. Common leiomyoma, lymphatic sarcoma, synovial sarcoma and so on. Hematogenous metastasis can occur early. The incidence of sarcoma accounts for 15-20% of childhood tumors and 1% of cheng human tumors. Thousands of patients and their families around the world are battling sarcoma. Due to a lack of awareness of sarcoma, early clinical symptoms are not taken seriously, resulting in 60 percent of patients present with advanced stage. Moreover, its early symptoms are not obvious, and it is often misdiagnosed as injury or arthritis, etc. 50% of the patients are delayed because they cannot get timely diagnosis and standard treatment. When determining the diagnosis, the tumors are often large, difficult to remove or have metastases, and they are faced with the double threat of forced amputation or distant metastasis due to postoperative local recurrence and life-threatening. Sarcoma patients often have irregular dull pain discomfort in the limbs in the early stage of the disease, which has nothing to do with exercise and is obvious at night. Gradually appeared swelling, mass, accompanied by skin temperature rise, venous rage and other manifestations. When the mass is increasing and the symptoms are getting worse, you should go to the bone tumor specialist of each hospital in time. Due to the extremely complex classification and diagnosis of sarcoma, it is difficult to make a correct diagnosis solely based on clinical examination and imaging. Biopsy is the necessary approach for the diagnosis of most sarcomas and can be said to be the "gold standard" for the diagnosis of sarcomas. Biopsy is divided into puncture biopsy and open biopsy. Open biopsies tend to be performed after a failed needle biopsy, with an incision of about 6-8 cm, with high trauma and slower recovery. After open biopsy is carried out in some hospitals, it is difficult for the second extensive limb salvage operation to remove the tumor, so that the patients lose the chance of limb salvage. Puncture biopsy uses thick trocar, which has the advantages of low cost, little trauma, quick recovery, etc. Chemotherapy drugs can be applied the second day after puncture, and this method is more respected. The earlier sarcoma is found, the higher the cure rate. Standardized comprehensive treatment is the key to cure sarcoma. The first diagnosis and treatment is directly related to whether the patient can retain the limb function, and the best time for treatment is the first operation. After the operation combined with chemoradiotherapy integrated individualized treatment, the safe limb preservation rate reached more than 90%.
