Statistical evidence that indicates that cure rates achieved by supervoltage are not significantly different from those achieved by orthovoltage in carcinoma of the tonsil and of the ovary is presented. The higher depth dose of supervoltage therapy may produce severe damage to structures about the tumor, and the assumption that a greater number of cures will result because of dose increase must be balanced against the well documented fact that severe damage to the tumor bed lessens rather than increases the proportion of cures. To evaluate the relative benefits, 2 forms of cancer were selected for review. Cancer of the tonsil was chosen as an example of a relatively accessible tumor and cancer of the ovary as a deep seated tumor. A list was made of the number of cases treated, the number of 5-yr survivals, and the voltage range. The survey showed that the increased cost of supervoltage is not associated with better cure rates. (H.H.D.)
