Salvage Radiotherapy Combined With Hormonotherapy in Oligometastatic Pelvic Node Relapses of Prostate Cancer

Summary

There is an increasing number of reports describing the existence of a proportion of prostate cancer patients who present with a reduced number of metastases (\<5 lesions) at relapse. This oligometastatic status has also been recognized in other tumor types such as melanoma, soft tissue sarcoma, liver, lung, and breast cancer, and has influenced the management of these malignancies in that a more radical treatment such as surgical resection has been employed. Positron Emission Tomography-Computed Tomography (PET-CT) studies with tracers such as choline or acetate are reliable tools to help with the diagnosis of oligometastatic disease after biochemical treatment failure in prostate cancer. An aggressive treatment combining androgen depriving therapy (ADT) and and high-dose irradiation to the oligometastatic lesions, as detected by PET-CT, may be proposed for these oligometastatic patients. Such a treatment strategy may hypothetically succeed to prolong the failure-free interval between two consecutive ADT courses, or even cure selected patients with limited metastatic burden. In this study the investigators plan to assess biochemical or clinical relapse-free survival at 2 years of prostate cancer with 1-5 oligometastases treated concomitantly with high-dose conformal Radiation Therapy and LH-RH agonists.
