Summary
Expedited salvage radiotherapy for prostate cancer significantly shortens treatment duration to approximately 5 weeks, offering a convenient and effective option with low toxicity. This hypofractionated approach shows promising efficacy for men with biochemical recurrence post-prostatectomy.
Area of Science:
- Oncology
- Radiation Oncology
- Urologic Oncology
Background:
- Standard post-prostatectomy radiotherapy requires 6.5-8 weeks.
- Salvage radiotherapy is crucial for managing biochemical recurrence after prostatectomy.
- There is a need for more efficient treatment schedules.
Purpose of the Study:
- To evaluate the safety and efficacy of an expedited hypofractionated radiotherapy course for salvage prostate radiotherapy.
- To determine the treatment duration, toxicity rates, and oncologic outcomes of this accelerated schedule.
Main Methods:
- 108 patients received 65 Gy in 26 fractions (2.5 Gy/fraction).
- Median follow-up was 32.4 months.
- Presalvage prostate-specific antigen (PSA) and Gleason score were recorded; some patients received androgen deprivation.
Main Results:
- Actuarial freedom from biochemical failure was 67% at 4 years.
- No acute grade 3 gastrointestinal or late grade 3 toxicities were observed; one acute grade 3 genitourinary toxicity occurred.
- Higher Gleason score and negative margins were associated with biochemical failure on multivariate analysis.
Conclusions:
- Hypofractionated radiotherapy (65 Gy in 2.5 Gy fractions) reduces treatment time by 1.5-3 weeks.
- This approach demonstrates encouraging efficacy and low toxicity rates at 4-5 years.
- Hypofractionation offers a convenient, resource-efficient, and well-tolerated salvage option for biochemical recurrence post-prostatectomy.
