Supervoltage radiotherapy for XXXX : CCABC technique and results.

@entity1 @entity1109 @entity134 @entity4610 @entity6875 @entity288
A treatment technique employing retrobulbar supervoltage radiotherapy (XRT) in @entity6875 is described. Twenty-eight @entity1 have been treated and followed between 1980-1983. Twenty-six of 28 @entity1 (93%) showed some response, with 19/28 (68%) having a good to excellent response. Four of 28 (14%) had recurrent symptoms post-XRT. Soft tissue signs and symptoms were relieved and disease progression arrested in the majority of @entity1 , but proptosis and @entity4610 responded poorly. High dose @entity288 have generally been the alternative form of therapy for this disease. Post-XRT, 24/28 (86%) of @entity1 have had no further @entity134 requirements, and been spared the associated complications. Treatment was well tolerated, with only five @entity1 (18%) demonstrating a transient @entity1109 which settled entirely within 2 weeks. No long-term complications have been encountered. Eleven @entity1 had post-XRT CT scans which were compared to pre-treatment scans and clinical response. Nine of 11 @entity1 (82%) had CT changes in general agreement with the observed clinical response, but the degree of involvement seen on the initial CT scan was not predictive of response nor the risk of relapse. XRT with the described technique is felt to be an effective, safe, and practical approach to the disabling and disfiguring complications of severe @entity6875 .
