A phase IB clinical trial of 15  Gy HDR brachytherapy followed by hypofractionated/SBRT in the management of intermediate-risk prostate cancer

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.

Authors: Konat-Bąska K, Chicheł A, Staszek-Szewczyk U, Maciejczyk A, Matkowski R Abstract Purpose: Prostate and colorectal cancers are the first and the third most popular malignancies in male population, in which some patients may develop these tumors metachronously or synchronously. At present, there are no standard recommendations, and oncologists need to provide an optimal management for two different cancers with an acceptable risk of possible treatment of adverse effects. Material and methods: This case report presents the treatment of a 61-year-old patient suffering from synchronous prostate and rectal...

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...

The age-old question in prostate cancer is which treatment is better, radical prostatectomy (RP) or external beam radiation therapy (EBRT)? Typically, RP failed at the margins of resection, whereas EBRT failed at the site of origin, and survival rates were the same. However, with low-dose rate (LDR) brachytherapy (BT), one can deliver high, ablative doses to the prostate, while also covering the edges, thereby capturing the best of both worlds.

Conclusion: The study did not demonstrate a significant benefit in administering resistant starch over and above normal diet to patients receiving pelvic radiotherapy. The reasons may be attributed to concurrent use of chemotherapy and decrease in intestinal probiotics. The use of digestible starch in the control arm may have contributed to lower incidence of the toxicity endpoints as well.

For patients with unfavorable or high-risk prostate cancer, dose escalated radiation therapy leads to improved progression free survival but attempts to deliver increased dose by external beam radiation therapy (EBRT) alone can be limited by late toxicities to nearby genitourinary and gastrointestinal organs at risk. Brachytherapy is a method to deliver dose escalation in conjunction with EBRT with a potentially improved late toxicity profile and improved prostate cancer related outcomes. At least three randomized controlled trials have demonstrated improved biochemical control with the addition of either low-dose rate (LD...

AbstractProstate cancer is the most common cancer among men in the USA. Interestingly, recent studies suggest that patients with inflammatory bowel disease (IBD) are at increased risk of developing prostate cancer. Importantly, patients with IBD who develop prostate cancer require thoughtful care when using immunosuppressants to treat the IBD in the setting of malignancy. Further, consideration must be given to the proximity of the prostate to the gastrointestinal tract when treating with radiation where there is concern for the effects of inadvertent exposure of radiation to the diseased bowel. In general, management of i...

Whole pelvis radiation therapy (WPRT) may improve clinical outcomes over prostate-only radiation therapy (PORT) in high-risk prostate cancer patients by sterilization of micrometastatic nodal disease, provided there is optimal control of the primary site.

There is now clear evidence of improved biochemical disease free survival (bDFS) with radiotherapy dose-escalation in all prostate cancer (PCa) risk groups [1,2]. Despite the advent of new techniques, external beam radiotherapy (EBRT) is limited in dose escalation due to the continuous change in the position, shape and volume of the target volume as well as the organs at risk (OARs). High-dose-rate brachytherapy (HDR) is a recommended treatment of eligible patients with prostate cancer as a method of dose escalation in conjunction with external beam radiation therapy according to the American Society of Clinical Oncology&a...
