Radium-223 vs EBRT for Multiple Painful Bone Metastases: Is Less More?

April 15, 2014

There is no question that radiopharmaceuticals have a role in the management of patients with metastatic bone disease. There is also no question that fractionated external beam radiotherapy (EBRT) is highly effective and generally well tolerated when delivered with large open or focal fields.

Radium-223: Down to the Bone, and Less Is More

April 17, 2012

Radium-223 is a promising agent that represents a new class of alpha pharmaceuticals that gets down to the site of bony metastases. The limited side-effect profile potentially allows for repeat administration to increase durability of pain control, and for its use in combination with novel biologic and chemotherapeutic agents.

Benefits and Pitfalls of Prostate Cancer Screening: “No Proof of Benefit” Does Not Equal “Proof of No Benefit”

May 12, 2011

Prostate cancer screening using prostate-specific antigen (PSA) testing has been a contentious subject.

Who, When, Where, and How: Salvage Prostate Cancer With Radiotherapy

July 15, 2010

Despite the common use of postoperative radiotherapy (RT) in patients managed initially with radical prostatectomy (RP), a number of questions remain. Raldow and colleagues build their arguments around three randomized trials that indicated a significant benefit of immediate adjuvant radiotherapy in patients with high-risk features.

Treatment of Prostate Cancer in Obese Patients: Review 2

September 01, 2006

Obesity is a complex, chronic disease that has reached epidemic proportions in the United States. Obesity is now linked with numerous health conditions, including many oncologic diagnoses. Its association with prostate cancer, the most prevalent cancer in men, has also been investigated, with studies suggesting a direct relationship between increasing obesity and prostate cancer mortality. Outcomes data for specific interventions in obese patients with prostate cancer have only recently begun to emerge. Surgery, while feasible even in the very obese, may result in less than optimal cancer control rates. Brachytherapy data are emerging, and are promising. No outcomes data are available for the use of external-beam radiation in obese patients. Long-term data for external-beam radiation, as well as for surgery and brachytherapy, are required to determine the most appropriate treatment for obese patients with prostate cancer. These data, coupled with a more thorough understanding of the biochemical relationship between obesity and prostate cancer, will be necessary to make optimal management decisions for obese patients with prostate cancer in the future.

Integrating Hormonal Therapy With External-Beam Radiation and Brachytherapy for Prostate Cancer

January 01, 2005

The use of hormonal therapy with external-beam radiation (EBRT)to treat prostate cancer is a topic that has been well explored. The potentialuse of hormonal therapy and brachytherapy in the treatment ofprostate cancer, however, continues to be controversial. This review isbased on our current interpretation of the available literature assessingthe outcomes of patients treated with EBRT and brachytherapy withor without hormonal therapy. Extrapolating from the findings of theRadiation Therapy Oncology Group (RTOG) 9413 trial, there appearsto be a favorable interaction between hormonal therapy and irradiationin the lymph nodes. The benefits demonstrated with whole-pelvicEBRT and hormonal therapy are likely to extend to patients treatedwith brachytherapy as well. Studies suggest that the role of hormonaltherapy in brachytherapy is limited without the application of wholepelvicEBRT due to the inability of brachytherapy to address potentiallymph nodes at risk. The potential role of hormonal therapy in conjunctionwith brachytherapy without pelvic radiotherapy, is limited byinconclusive data and abbreviated follow-up times.

PSA After Radiation for Prostate Cancer

May 01, 2004

In this paper, Dr. Kuban et al addresscontroversies surroundingthe use of posttreatment prostatespecificantigen (PSA) in determiningoutcome after radiotherapy. They basemost of their discussion on their ownobservations of prostate cancer outcomesin more than 4,000 patients followingexternal-beam radiotherapyalone.[1,2] I had the privilege of writingan editorial on their earlier companionpapers, and I made the argumentthen that although some definitionswere slightly better than the AmericanSociety for Therapeutic Radiology andOncology (ASTRO) definition, the differenceswere not impressive enoughto recommend changing the standardfor determining outcome after external-beam radiotherapy.[3]

Spectroscopy in Prostate Cancer: Hope or Hype?

November 01, 2001

Clinical applications of image-based radiation therapy for the study of prostate cancer have expanded significantly over the past years. The results of recent studies of magnetic resonance imaging (MRI) combined with magnetic

Evidence for Cure of ‘Young’ Men With Prostate Cancer

May 01, 2001

In this issue of ONCOLOGY, Dr. Hanks further establishes his legacy by leading the charge for radiotherapy as the treatment of choice in men with clinically localized prostate cancer. Most urologists and some radiation oncologists tend to consider

Contemporary Hormonal Management of Advanced Prostate Cancer

April 01, 1998

The traditional definition of “advanced” prostate cancer includes only patients with widespread osteoblastic or soft-tissue metastases (clinical or pathologic stage T any N any M1; or stage D2). Current evidence indicates that
