The Myths and Facts About Prostate Brachytherapy

As part of a special course on brachytherapy for prostate cancer from the American Brachytherapy Society and Grand Rounds in Urology, Steven J. Frank, MD, Professor of Radiation Oncology at the University of Texas MD Anderson Cancer Center, Medical Director of the Proton Therapy Center at MD Anderson, and leader of both the Proton Therapy Program for Head and Neck Cancer and the Prostate Brachytherapy Program, introduces the many myths about brachytherapy and dispels them with data, revealing the truth of brachytherapy and its effects. He shows data asserting that patients under 60 and obese patients are great candidates for brachytherapy. Dr. Frank then discusses how radiation exposure to a patient’s family is less than what a flight from New York City to San Francisco would cause, and that brachytherapy has great curative ability based on a PSA of .2 ng/ml at 4 years being curative. He describes how long-term data and outcomes for brachytherapy are in the treatment’s favor, showing that it is an excellent option for low-, intermediate-, and high-risk cancer. Dr. Frank states that patient satisfaction is greater with brachytherapy than other treatments due to low rates of urinary incontinence and reduction in sexual function, and no penile shortening or treatment regret. He summarizes how salvage therapy and salvage brachytherapy following radiation have been found to be effective but require skilled and experienced teams. Dr. Frank also discusses asymptomatic seed migration 3 years after implantation, the lack of data on hair loss, the safety of cremation, and how MRI-assisted radiosurgery is an innovation in brachytherapy. He concludes that brachytherapy has been found to be the most innovative, cost-effective, satisfying, and curative prostate cancer treatment.

Updates in Upper Tract Urothelial Cancer: Challenges in Diagnosis and Treatment

Surena F. Matin, MD, the Monteleone Family Foundation Distinguished Professor in the Department of Urology at MD Anderson Cancer Center, gives an overview of upper tract urothelial carcinoma (UTUC), comparing it to bladder UC and outlining risk factors, imaging options, and possible treatment paths. He posits that the lack of research on UTUC is a major reason for the challenges in diagnosing and treating the illness. When compared to bladder UC, UTUC has more imprecise staging options, more anatomical barriers for therapy, and unclear lymphadenectomy templates. Dr. Matin identifies UTUC risk factors such as tobacco, exposure to aromatic amines and arsenic, and also discusses classification issues related to patients with hereditary UTUCs. He then discusses how imaging is the backbone of staging and grading, but has limitations, recommending a CT chest scan or chest X-ray to rule out metastases, a cystoscopy to assess bladder capacity, and a ureteroscopy to assess tumor size. Dr. Matin concludes with a discussion of radical nephroureterectomy as a treatment option, stating that it is highly curative but at the cost of kidney function. He believes that adjuvant topical therapy could help solve the problem of treatment options but notes that there is not enough data to be certain of this yet.
