Twelve consecutive patients with advanced lymphoepithelioma and no previous chemotherapy or radiotherapy were observed in our Division between January 1975 and December 1980. Primary treatment of 11 evaluable patients with doxorubicin (Adriamycin), bleomycin, vinblastine, and dacarbazine (ABVD) for at least three cycles resulted in complete remission (CR) in four patients; partial remission with a less than 50% reduction of tumor volume in four; partial remission with a greater than 50% reduction of tumor volume in one; and no response in two. With the addition of radiotherapy in doses of 4500-6000 rad to the primary tumor and the bilateral laterocervical lymph node chains, the combined treatment resulted in CR in eight patients. At 27 months the median duration of CR in these patients has not been achieved, and the median survival has not been achieved at 32 months.
