Radiotherapists are among the few cancer clinicians who speak in terms of “cures” rather than the “response rates” or “remission rates” favored by chemotherapists and immunotherapists. This exceptional optimism may be justified. Radiotherapists can, for example, cure 55 to 65 percent of patients with locally inoperable cancer of the prostate and as many as 30 percent of patients with cancer of the urinary bladder, both of which are not susceptible to other types of therapy. In fact, according to Frederick W. George III of the National Cancer Institute (NCI), Bethesda, Maryland, some 60 percent of all cancers are potentially curable with current techniques of irradiation.
