[Salvage prostate brachytherapy: A solution for local failures after a primary radiation therapy?]

Area of Science:

• Oncology
• Radiation Oncology
• Urology

Background:

• Salvage brachytherapy is an emerging treatment for prostate cancer recurrence after initial radiation therapy.
• Early diagnosis of isolated local failure is improved by advances in imaging (multiparametric MRI, PET-CT) and targeted biopsies.
• This approach is considered for patients with localized prostate cancer failure who may still be candidates for cure.

Purpose of the Study:

• To evaluate the efficacy and safety of salvage brachytherapy for recurrent prostate cancer.
• To compare incontinence rates with other salvage treatments.
• To discuss the current consensus on patient selection and areas needing further research.

Main Methods:

• Utilizes brachytherapy implantation accuracy with 3D dosimetry.
• Patient selection criteria are being refined based on disease characteristics at baseline and recurrence.
• Data from phase II studies and literature review are considered.

Main Results:

• Achieves over 50% long-term tumor control rates.
• Results in lower incontinence rates compared to radical prostatectomy, HIFU, or cryotherapy.
• Consensus exists on defining suitable candidates for salvage brachytherapy.

Conclusions:

• Salvage brachytherapy is a viable option for select patients with recurrent prostate cancer.
• Further controlled trials are needed to establish optimal techniques, dosage, and implantation volumes.
• The technique is included in NCCN guidelines but requires precise evaluation.
