soft tissue benign tumor resection

The most widely used treatment for soft tissue tumors is radical surgery, which involves amputation, radical resection of the entire affected muscle mass and/or removal of adjacent affected tissue. Treatment of diseases: liposarcoma rhabdomyosarcoma Indication Benign tumors, no lymphatic metastasis. Contraindications 1. The tumor is small, there are surgical contraindications or the patient refuses surgery. 2, multiple recurrence of surgery, should not be operated again. 3, palliative treatment, tumors, and limited lymph node metastasis. Preoperative preparation Preoperative radiotherapy For some tumors that grow rapidly and are radiation-sensitive, preoperative radiotherapy can reduce tumors by 30% to 90%. The purpose of pre-radiation therapy is to reduce the chance of local recurrence of surgery, and to replace amputation with some extensive resections and to preserve useful limbs. Irradiation precautions: For embryonal rhabdomyosarcoma, synovial sarcoma with poorly differentiated growth, liposarcoma, fibrosarcoma, etc., the range of irradiation field should be appropriately expanded, and if possible, it is best to include the entire length of the invaded muscle (muscle Starting and ending points). When the tumor is close to the lymphatic area (the distance between them is less than 10 cm), the range of illumination should include the adjacent lymphatic area. complication 1. Skin damage: Subcutaneous tissue fibrosis can occur after high-dose irradiation, and the skin covering the fibrotic surface becomes ischemic, prone to ulceration and necrosis in the later stage. Especially in some areas that are vulnerable to trauma and friction, slight external stimuli may cause local ulceration and prolonged unhealed. 2, muscle damage: muscle fiber fibrosis may occur after high dose irradiation, most patients with muscle fibrosis is not serious, the patient can tolerate. A small number of patients affect the motor function of the limb because of the simultaneous subcutaneous and muscle fibrosis. Injury of bones and joints: After high-dose irradiation, a small number of patients may have pathological fractures under the inducement of trauma. 3, treatment: Once the sequelae of radiotherapy appear, the treatment is very difficult, the key is prevention. For limb lesions, do not illuminate the entire circumference of the limb. It is necessary to keep a fairly wide area outside the irradiation range to prevent fibrosis of the limb and ischemic necrosis of the skin. As the dose increases, the irradiation field should be reduced in time. For lesions on the chest wall and abdominal wall, tangential irradiation should be used as much as possible to avoid damage to the internal organs. Irradiation of the joint should generally be avoided or reduced unless the lesion invades the joint or adjacent joint.
