AIMS: To report outcomes of adults with @entity242 ( @entity242 ) treated by surgery, external beam radiotherapy (EBRT) and intraoperative electron beam radiotherapy (IORT). METHODS: From July 1988 to February 2001; 24 @entity1 with primary and recurrent @entity242 were diagnosed and treated. The median dose and energy of IORT delivered was 15 Gy/9meV. EBRT dose varies between 45-50 Gy. RESULTS: There were five primary and 19 recurrent @entity5 . One primary and five recurrent @entity5 underwent R0 resection. There were 12 @entity1821 and 19 grade I @entity5 ; 13 @entity1 developed local recurrence and three developed distant metastases.Twenty-two @entity1 received IORT associated with EBRT: 11 developed recurrences. Six @entity1 developed @entity2359 (4 grade II and 2 grade III). Disease free survival and overall survival at 5 years was 28 and 56% respectively. CONCLUSIONS: EBRT with IORT treatment is a promising technique for local control. Lower recurrence rates are associated with radical (R0) surgical procedures.
