An Example of Futile Spending: Preventive Screening at End of Life
November 5th 2010Looking at contemporary medicine’s complex landscape, especially in regard to soaring costs, can make practitioners dizzy. For example, if primary care physicians were asked whether it is cost-efficient and reasonable to screen with prostate-specific antigen (PSA) measurement for early-stage prostate cancer in men with terminal pancreatic cancer or to perform colonoscopy for early diagnosis of colon cancer in women with stage IV lung cancer, the answer would be a quick and uniform no. Unfortunately, a recent publication suggests that in the real world the answer has been yes, as disturbing and wasteful as that may be.
Benign Prostatic Hyperplasia: Current Treatment Strategies
February 2nd 2009Benign prostatic hyperplasia (BPH)-histologically defined as stromal and epithelial hyperplasia beginning in the periurethral transitional zone of the prostate-affects up to 80% of 80-year-old men.[1,2] With progressive prostatic enlargement, bladder outlet obstruction can result. Although the exact mechanism is unknown, lower urinary tract symptoms (LUTS) can signal progressive BPH.
Updated Guidelines Give Thumbs Down on PSA Screening in Older Men
October 2nd 2008To screen or not to screen? The answer is not straightforward when it comes to prostate cancer. Recently updated guidelines from the US Preventive Services Task Force (USPSTF) recommend against prostate- specific antigen (PSA) screening in men who are 75 years and older and state that there is insufficient evidence to confirm whether screening is beneficial-or harmful -to men younger than 75 years.1,2 The recommendations are summarized in the Table.
ASCO PROSTATE: Imaging Not Helpful in Men With Low PSA in Biochemical Failure
February 27th 2007KISSIMMEE, Fla. -- After definitive prostate cancer therapy, there is little value in imaging studies when patients with biochemical failure are asymptomatic and have PSA levels less than 5 ng/mL, researchers here reported.
ASCO PROSTATE: More Radiation Improves PSA Control but Increases Toxicities
February 26th 2007KISSISSIMEE, FLA. -- Escalated-dose conformal radiotherapy for localized prostate cancer was associated with a 34% reduction in the relative risk of biochemical failure in a randomized trial of 843 men also with treated with androgen deprivation therapy.

PSA Screening Should Emphasize Changes Over Time, Study Suggests
December 6th 2006PSA velocity, not a man's absolute PSA level, is a better predictor of prostate cancer risk, according to a study from the Johns Hopkins School of Medicine. The findings suggest that screening should begin at age 40, not 50.
Shedding Light on the Controversy Over Vitamin D
December 1st 2006During a routine checkup, a middle-aged woman asks you whether she should stop wearing moisturizers and makeup that contain sunscreen. She has read that increased sunlight exposure enhances vitamin D production, which may prevent certain types of cancer. What would you tell her?
PSA Recurrence of Prostate Cancer:
December 1st 2006ABSTRACT: Prostate-specific antigen (PSA) recurrence is the most common form of advanced prostate cancer. Salvage therapies may be effective even among some high-risk men, although long-term cancer control data are limited. The natural history of PSA recurrence is long but variable. The postrecurrence PSA doubling time can identify men at high risk for progression and death. Early hormonal therapy, possibly via combined androgen blockade, may reduce the risk of progression and improve cancer-specific survival among men with high-risk recurrence. Men with low-risk recurrences likely receive minimal benefit from aggressive early hormonal therapy and may actually be harmed.
PSA Screening Rates for Elderly Men Found Too High
November 14th 2006SAN FRANCISCO -- Older men with limited life expectancies are getting screened much too often for prostate cancer, given the potential harm that may follow a positive test versus the likelihood of benefit, researchers here reported.
