Radiotherapy for patients with locoregional and oligometastatic relapses of prostate cancer after radical prostatectomy

Materials and methods. In our study, 21 patients with recurrent prostate cancer after radical prostatectomy and oligometastases were treated by salvage radiation therapy, which included radiotherapy treatment of recurrent tumors, regional pelvic lymph nodes, the prostate bed and stereotactic body radiation therapy to detected solitary metastases.Results. The average follow-up period was 19 ± 3.5 months. At the same time, 12 (57 %) of 21 patients are currently under observation for more than 1 year, and 1 patient for more than 5 years without signs of a biochemical recurrence. The indicator of biochemical control of the disease was 86 % (18 / 21 patients) with an average follow-up period of 19 months.Conclusion. It seems to us that further study of this problem can replace today's palliative standard of treatment for this special category of patients — hormonal and chemotherapy treatment, which has low effectiveness at a high incidence of toxicity.
