The importance of a multidisciplinary group in the treatment of soft tissue sarcomas. Wiklund T, Huuhtanen R, Blomqvist C, Tukiainen E, Virolainen M, Virkkunen P, Asko-Seljavaara S, BjЖrkenheim JM, Elomaa I.

In 1987, a multidisciplinary soft tissue sarcoma (STS) group was established and a treatment protocol was set up. By 1993, there were 193 patients with a diagnosis of STS of the superficial trunk or extremities. 134 patients were referred with primary (stage M0) tumours and treated with curative or palliative intention. Nine amputations were performed. 94 (70%) patients were treated with wide or compartment surgery (n = 62) or marginal surgery combined with postoperative radiotherapy (n = 32). According to the protocol, these patients had received adequate treatment. 18 patients have recurred locally (13%) (median follow-up: 36 months). 12 were salvaged. 33 had metastases. The estimated 3-year survival, local control and disease-free survival rates are 79, 87 and 69%, respectively. These results compare favourably with previously published results from this hospital and from a nationwide study. The improved results emphasise the importance of a multidisciplinary STS group.

Soft tissue sarcoma: An overview. Goldberg BR.
Department of Orthopaedics, Mayo Clinic Arizona, 5777 East Mayo Boulevard, Phoenix, AZ 85259, USA.
Malignancy of soft tissue, referred to as sarcomas, are some of the rarest tumors in medicine. These tumors account for approximately 1% of all diagnosed malignancies. Diagnosis of soft tissue sarcoma (STS) is a complex process that includes history and physical examination of patient, diagnostic imaging studies, and biopsy when indicated. All clinicians should be able to identify the unique characteristics of malignant soft tissue tumors and assist patients with obtaining care from a specialist in the treatment of STS. Evidence-based medicine has shown that the critical difference in treating STSs is a multidisciplinary approach.
