Complete regression of advanced liposarcoma of the anterior chest wall with interferon-alpha and tumor necrosis...

This paper reports a case of complete regression of a liposarcoma in a 62-year-old Japanese man who, in August 1986, presented with a giant subcutaneous tumor of the right anterior chest wall. Local radiotherapy and conventional chemotherapy were initially performed; however, the tumor did not respond at all. He then received cytokine treatment (interferon-alpha and tumor necrosis factor-alpha). Nineteen months after cytokine treatment, the mass disappeared totally. The patient has been in complete remission for five years without recurrence and with no additional treatment. This suggests that the use of interferon-alpha and tumor necrosis factor-alpha in combination may be an effective and promising modality for liposarcomas which are refractory to the conventional anticancer treatments.
