TREATMENT OF ADVANCED AND INACCESSIBLE SARCOMAS WITH CONTINUOUS INTRA‐ARTERIAL CHEMOTHERAPY PRIOR TO DEFINITIVE SURGERY OR RADIOTHERAPY—A POSSIBLE ALTERNATIVE TO AMPUTATION OR DISABLING RADICAL SURGERY

Abstract

Four patients with advanced and inaccessible soft tissue sarcomas were treated with a regimen of intra-arterial chemotherapy followed by radiotherapy and/or surgical excision. Two of the patients had advanced sarcomas in the buttock and thigh regions which would otherwise have required hindquarter amputation in one case or disarticulation of the hip in the other case. These sarcomas responded significantly to intra-arterial chemotherapy to the extent that subsequent local surgery was effective in eradicating the residual tumours. No viable tumour cells were found in the resected specimens. In both patients amuputation was avoided and local tumour eradication was achieved. In the other two patients, advanced and non-resectable sarcomas in the head were first treated with a similar regimen of intra-arterial chemotherapy. In both cases the tumours regressed in size prior to administration of local radiotherapy. After completion of chemotherapy and radiotherapy no viable tumour cells were detected in either lesion. In one case (originally a very extensive sarcoma of the jaw in a 5 year old child) a residual lump was resected but no viable tumour was detected in the resected specimen. These four patients represent our total experience with this plan of management. All responded well and there has been no evidence of local disease recurrence in any of the four patients. One patient (Case 2) did develop pulmonary and bone metastases from which she died 2 years later but the other three patients remain well with no evidence of residual disease, 11 years, 4 years and 20 months after presentation.
