Soft tissue tumors are clinically common, and the origins of the tumor tissue origin are complex with multiple types, but the treatment principles are basically identical, hereby we would like to introduce the following treatment methods:
1. Radical operation: tumors together with the surrounding normal tissue must be removed at the same time, in order to ensure complete resection, often some normal tissue structures, parts, skins or adjacent partial muscles are also removed; 2 debulking operation; 3. amputation.
Complete radical operation can cause functional injury, amputation or joint disarticulation, so another choice is combined application of operation and radiotherapy. After operation, radiotherapy can be applied to pay the inhibition role for tiny subclinical lesions remained within the operation field, but it is ineffective to those large tumors in lump-like or in nodular shape.
1. Chemotherapy prior to operation: for those soft tissue tumors of large volume and in high malignancy, preoperative chemotherapy is preferred to decrease the volume and increase the resection rate so that avoid suffered amputation.
2. Chemotherapy after operation: surgery combined with chemotherapy, has been widely used in the clinical treatments of various malignant tumors. In the treatment of highly malignant soft tissue sarcomas, chemotherapy should be begun to use shortly after operation. It is possible to reduce distant metastasis and improve the survival rate.
Gene targeted therapy, is targeted at clearly-defined carcinogenic site (the site may be a protein molecule or a genetic fragment inside of tumor cells) and then to design corresponding treatment drugs. The drugs will specifically select and work on the carcinogenic sites to bring death to tumor-specific cells without affection to surrounding normal tissue cells. Simply say, it first correctly seeks the tumor target——a gene, and then destroy it. Or let’s say, it precisely targets at key carcinogenic site of cancer cell growth (such as enzymes, proteins, receptors, etc.), and then launches a guided “missile" to destroy growth of cancer cells.
