Effect of Lap-Band Induced Weight Loss on Serum PSA Levels

The proposed prospective study aims to determine whether interpretation of PSA levels in morbidly obese men require correction due to the obesity itself. If PSA levels are found to rise after weight loss, interpretation of PSA levels in morbidly obese men may be improved by upward correction of the PSA level. A 'correction factor' may be proposed for the interpretation of PSA levels in obese men, toward the clinical decision regarding indication for prostate biopsy.

Primary Outcome Measures:
  • PSA value [ Time Frame: 18 months ]

Secondary Outcome Measures:
  • quality of life, testosterone, esradiol, leptin, HbA1c, cholesterol, prostate volume [ Time Frame: 18 months ]

Biospecimen Retention:   Samples Without DNA
blood samples

Estimated Enrollment: 20
Study Start Date: November 2007
Estimated Study Completion Date: December 2009
Groups/Cohorts Assigned Interventions
1 Procedure: Bariatric Surgery
one time lapb-band gastric bypass surgery

Detailed Description:
The main objective of this study is to determine whether interpretation of PSA levels in morbidly obese men require correction due to the obesity itself. Secondary outcome measures that will be followed include the affect of obesity and weight loss on testosterone, estradiol and leptin. In as much as these might also affect PSA, we will be measuring these values as well. Also, we do not know the effects of lap-band induced weight loss on clinical outcome measures of sexual, bowel and urinary function. Thus we will aim to investigate these parameters as well.
