Bösartige Weichgewebsgeschwülste

Soft tissue sarcomas are a rare and heterogeneous group of tumors. Surgery clearly remains the standard therapy of non-metastatic soft tissue sarcoma. A pretreatment biopsy is necessary to determine the histology and grade of soft tissue sarcomas and to diagnose entities that can be treated by targeted therapies, such as dermatofibrosarcoma protuberans or alveolar soft tissue sarcoma once they are in a metastatic stage. Nevertheless, locally advanced disease requires multimodal treatment and interdisciplinary treatment decisions. Limb sarcoma of borderline resectability (encasement of vessels, invasion of joints or close proximity to motor nerves) may profit from isolated limb perfusion with recombinant tumor necrosis factor and melphalan. Preoperative chemotherapy may be applied in locally advanced high grade tumors when clear resection margins are difficult to achieve. Deep wave hyperthermia has proven to be a useful addition to systemic chemotherapy in such a neoadjuvant setting. Also preoperative radiation therapy has proven to be effective in controlling locally advanced sarcoma despite higher perioperative morbidity which pays off in the long run by better limb function. Postoperative adjuvant external beam irradiation therapy with the best available technique is recommended for any tumor larger than 5 cm with (FNLCC) grades 2 and 3 (American Joint Committee on Cancer stage IIb/III). Given all these therapeutic options, it is absolutely crucial that interdisciplinary decision-making starts early in the therapeutic process. Patients are often seen first by the surgeon. For an optimal treatment surgeons need to know the efficacy and toxicity of the multimodal treatment options described.

Prevention of perioperative and postoperative complications resulting from surgical oncology in the pelvic region remains a major interdisciplinary challenge. With modern interdisciplinary concepts joining forces of various surgical specialties, tumor resection can be sufficiently carried out with wide margins and the patients benefit from reduced morbidity even in complex situations. As an example chronic fistulation and secretion from the presacral cavity and sinus may result as potential sequelae from intra-abdominal and intrapelvic tumor resection, especially when neoadjuvant multimodal therapies have been applied. This can be prevented by simultaneous transplantation of for example transpelvic vertical rectus abdominis myocutaneous (VRAM) flap transfer, while extensive perineal skin and soft tissue defects may also be simultaneously reconstructed. In cases of malignant soft tissue tumors in the pelvic region a staged surgical procedure can be performed with a period of time between tumor resection and reconstruction. Thus, a histological R0 status can be secured prior to plastic reconstruction surgery in order to increase oncological safety. In cases of postresectional exposition of e. g. pelvic or femoral vessels or intrapelvic and intra-abdominal organs simultaneous flap procedure is mandatory.The reconstructive armamentarium of the plastic surgeon should contain not only pedicled but also free microsurgical flaps so that no compromise in terms of the extent of the oncological resection has to be accepted. At the same time perioperative and postoperative complications may be avoided and the patient quality of life can be preserved even in more complex cases.
