Abstract
Long-term outcome of the Patterns of Care Study and the Radiation Therapy Oncology Group are used to demonstrate the national average results of treating early prostate cancer in the United States. A group of patients with stage T1B2 disease and pathologically negative lymph nodes showed excellent 10- year survival rates and freedom from clinical evidence of disease, while prostate specific antigen (PSA) correlations in 10-year survivors indicate that 88% were clinically free of cancer and had a PSA level of less than 4.0 mg./nl., and 65% had a PSA level of less than 1.5 ng./ml. The latter group represented clinical and biochemical cures. The improvement noted in outcome of locally advanced prostate cancer treatment by Radiation Therapy Oncology Group prospective trials combining androgen deprivation and radiation therapy is presented. These trials will be extended to the poor prognosis group with stage T1,2 disease. The advantages of conformal therapy in acute and late morbidity are illustrated with preliminary evidence of improved PSA response as a result of improved technique and higher dose associated with conformal 3- dimensional treatment.
