Integrating Hormonal Therapy With External-Beam Radiation and Brachytherapy for Prostate Cancer

January 01, 2005

The use of hormonal therapy with external-beam radiation (EBRT)to treat prostate cancer is a topic that has been well explored. The potentialuse of hormonal therapy and brachytherapy in the treatment ofprostate cancer, however, continues to be controversial. This review isbased on our current interpretation of the available literature assessingthe outcomes of patients treated with EBRT and brachytherapy withor without hormonal therapy. Extrapolating from the findings of theRadiation Therapy Oncology Group (RTOG) 9413 trial, there appearsto be a favorable interaction between hormonal therapy and irradiationin the lymph nodes. The benefits demonstrated with whole-pelvicEBRT and hormonal therapy are likely to extend to patients treatedwith brachytherapy as well. Studies suggest that the role of hormonaltherapy in brachytherapy is limited without the application of wholepelvicEBRT due to the inability of brachytherapy to address potentiallymph nodes at risk. The potential role of hormonal therapy in conjunctionwith brachytherapy without pelvic radiotherapy, is limited byinconclusive data and abbreviated follow-up times.
