OBJECTIVE Hyperthermic isolated limb perfusion (HILP) with tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma), and melphalan is associated with a dramatic antitumor effect in locally advanced extremity soft-tissue sarcomas (STS). The aim of this study was to demonstrate the feasibility and efficacy of adjuvant radiotherapy after HILP with TNF-alpha, IFN-gamma, and melphalan and delayed surgical resection. METHODS Between 1991 and 1995, 34 patients--16 males and 18 females, median age 50 (range 18-80) years--underwent HILP for locally advanced extremity STS. Resection of the residual tumor mass was performed in most patients after 6-8 weeks. Fifteen patients with histopathological viable tumor after resection received adjuvant 60-70 Gy external beam radiotherapy (EBRT) (44%, HILP + EBRT group). Nineteen patients received HILP without adjuvant EBRT (56%, HILP-only group). Five patients in the HILP-only group had also distant metastases (15%) and received HILP as a palliative treatment. Treatment morbidity, local recurrences, and regional and distant metastases were scored. RESULTS During a median follow-up of 34 months (range 8-54), limb salvage was achieved in 29 patients (85%): 14 patients after HILP + EBRT and 15 patients after HILP only. None of the patients from the HILP + EBRT group developed local recurrences; however, five patients from the HILP-only did (26%) (p < 0.05). Regional metastases were observed in one patient from the HILP + EBRT group (7%) and in two patients from the HILP-only group who were treated with curative intent (14%). Distant metastases occurred in four patients after HILP + EBRT (27%) and in four patients after HILP only with curative intent (29%). The mean morbidity (subjective, objective, medical management, and analytical evaluation) score in both groups was, respectively, 0.33 for skin and subcutaneous tissue and for muscle and soft tissue, 0.34 (HILP + EBRT group) and 0.33 (HILP-only group). CONCLUSIONS Adjuvant EBRT after HILP with TNF-alpha, IFN-gamma, and melphalan and delayed tumor resection of locally advanced extremity STS is feasible and may increase local tumor control without increasing treatment morbidity.

D006979 Hyperthermia, Induced Abnormally high temperature intentionally induced in living things regionally or whole body. It is most often induced by radiation (heat waves, infra-red), ultrasound, or drugs.

D007371 Interferon-gamma The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES.

D008558 Melphalan An alkylating nitrogen mustard that is used as an antineoplastic in the form of the levo isomer - MELPHALAN, the racemic mixture - MERPHALAN, and the dextro isomer - MEDPHALAN; toxic to bone marrow, but little vesicant action; potential carcinogen.
