Abstract:
【Objective】 To explore the effectiveness and safety of different salvage therapies for local recurrence of tumor following primary prostate cryoablation so as to provide the reference for the treatment of prostate similar cases. 【Methods】 The clinical data of patients with prostate cancer (cT1c-4N0M0) who received salvage therapy for local recurrence of tumor following primary prostate cryoablation in the Sun Yat-Sen University Cancer Center during June 2014 and Dec. 2020 were retrospectively analyzed. Salvage therapies included local therapy (salvage radiotherapy, salvage cryoablation or salvage radical prostatectomy) and androgen deprivation therapy (ADT). 【Results】 Altogether 8 patients were involved. The median age was 71(63-76) years, the median prostate specific antigen (PSA) at the first diagnosis was 17.650(10.380-325.100) ng/mL, the median nadir post-cryoablation PSA was 0.041(0.003-0.541) ng/mL, and the median PSA at local recurrence was 3.030(2.090-19.180) ng/mL. Abnormal digital rectal examination was found in 3 cases, and radiographic evidence of local recurrence was found in 7 cases. Prostate biopsy was performed in 4 cases, 2 of which had positive results. The median follow-up after salvage therapy lasted for 54 (9-75) months. Four cases received salvage radiotherapy, 2 of which developed bloody stool, hematuresis and urinary tract infection, and recovered after conservative treatment; 1 case received salvage cryoablation without side effects; 1 case underwent radical prostatectomy and radiotherapy, developed lymphorrhagia and recovered after conservative treatment; 2 cases received ADT alone, one experienced hot flashes and recovered after conservative treatment, and the other progressed into castration-resistant prostate cancer after 63 months. No other progression or death occurred at the termination of follow-up. 【Conclusion】 Salvase therapy (salvage radiotherapy, salvage cryoablation, salvage radical prostatectomy) and ADT can be used for local recurrence of tumor following primary prostate cryoablation. However, large-scale prospective research is needed to confirm the effectiveness and safety of different therapies.
