Prostate cancer patients who receive permanent radiotherapy implants twice as likely to be free of cancer after five years

Results from a randomised controlled trial to compare the use of permanent radioactive implants (brachytherapy) with dose-escalated external beam radiotherapy in patients with prostate cancer show that the men who received brachytherapy were twice as likely to be cancer-free five years later.

Men with Gleason grade Group (GG) 4 and 5 prostate cancer have high failure rates when treated by conventional therapy. We investigated the effect of higher radiation doses on freedom from biochemical failure (FBF) and prostate cancer mortality (cause-specific survival [CSS]) in men treated with a combination of permanent implant and external beam irradiation (EBRT).

High dose-rate (HDR) brachytherapy is commonly administered as a boost to external beam radiation therapy (EBRT). Our purpose was to compare toxicity with increasingly hypofractionated EBRT in combination with a single 15  Gy HDR boost for men with intermediate-risk prostate cancer.

Conclusions: This study highlights excellent outcomes for intermediate-risk prostate cancer patients, including unfavorable intermediate-risk cases, treated with BED ≥ 200 Gy radiotherapy using LDR brachytherapy. LDR alone with a BED of 200 Gy may be an optimal treatment for both favorable and unfavorable intermediate-risk prostate cancer patients, although a longer follow-up is mandatory to confirm the present findings.

Conclusions: The excellent long-term results and low morbidity presented as well as many advantages of prostate brachytherapy over other treatments demonstrates that brachytherapy is an effective treatment for patients with transurethral resection and organ-confined prostate cancer.

AbstractUrinary retention and hematuria owing to radiation-induced mucositis are occasional late adverse events in patients with prostate cancer. Moreover, radiation-induced secondary malignancies are late adverse events, although they are extremely rare. Herein, we describe a case of radiation-induced secondary malignancy of the prostate that was initially difficult to distinguish from radiation mucositis. A 74-year-old man with prostate cancer underwent brachytherapy and external beam radiotherapy 9 years ago. Twenty-eight months after irradiation, he presented with urinary retention and hematuria owing to radiation muco...

ConclusionIn this prospectively analyzed subcohort of patients with AS and conventional staging within a randomized trial, the 2-year histological reclassification rates were higher than those previously reported. Active surveillance may not be based on conventional staging alone, and patients with grade group 2 cancers may be recommended for active surveillance in carefully controlled trials only.

This study reports patterns of radical radiotherapy for PCa in Sweden over the past two decades.Materials and methods: All men with non-metastatic PCa (1998-2016) who received external beam radiotherapy (EBRT) or high or low dose-rate brachytherapy (HDR-BT/LDR-BT) were identified in PCBaSe. Analyses included: trends in radiation techniques, fractionation patterns and total doses over time; PCa-specific survival comparing treatment in 2007-2017 with 1998-2006; and regional variation in type of primary radiotherapy.Results: About 20,876 men underwent primary radiotherapy. The main treatment modalities include conventionally ...

Prostate cancer therapies are improving over time. But how do the long-term side effects from the various options available today compare? Results from a newly published study are providing some valuable insights. Investigators at Vanderbilt University and the University of Texas MD Anderson Cancer Center spent five years tracking the sexual, bowel, urinary, and hormonal status of nearly 2,000 men after they had been treated for prostate cancer, or monitored with active surveillance (which entails checking the tumor periodically and treating it only if it begins to grow). Cancers in all the men were still confined to the p...

For patients with localised prostate cancer, radical radiotherapy can be delivered with either external beam radiotherapy (EBRT) or brachytherapy (BT). Compared to EBRT, BT dosimetry offers the optimum in conformality, an unrivalled dose drop-off gradient beyond the gland markedly sparing normal tissues and enables extreme dose intensification to the prostate. Several randomised controlled trials have shown dose-escalation to significantly improve biochemical control [1 –5] and brachytherapy offers the most effective means of achieving this.
