Multiple scoring systems have been proposed to standardize the description of anatomical features of renal tumors. However, it remains unclear which of these systems, if any, is most useful, or whether any performs better than simply reporting tumor size or location in patients undergoing partial nephrectomy. To clarify these issues we evaluated the association of tumor size, location, R.E.N.A.L....
Objectives. To determine the prostate-specific antigen (PSA) levels and PSA change over time in young white and black men 20 to 45 years old.Methods. The Department of Defense Serum Repository, a serum bank that stores all residual serum from the military human immunodeficiency virus screening program at -25 o C, was sampled to obtain a total of 588 black and 588 white subjects 20 to 45 years...
Objectives. To assess the ability of pretreatment and post-treatment prostate-specific antigen (PSA) measurements, clinical tumor stage, tumor grade, Gleason sum, race, age, and radiation dose to predict the recurrence of prostate cancer following external beam radiation therapy (XRT) since the introduction of PSA as a tumor marker at one tertiary care center.Methods. The recurrence of prostate cancer...
Objectives. Prostate cancer (PCa) has a familial predisposition imparting an increased risk of developing the disease in those with a family history. The pathologic characteristics are similar to sporadic cases; however, the disease-free survival rates of hereditary PCa have recently been disputed, with one major study suggesting that familial cases have higher recurrence rates. Our study seeks to...
Objectives. To study, in a prospective fashion, acute traumatic effects on the gastrointestinal tract of patients treated by extracorporeal shock wave lithotripsy (ESWL).Methods. Stool samples from each of 54 patients were tested before and after ESWL for conversion to hemoccult positive. A minimum of one negative pre-ESWL stool guaiac test was required for inclusion into the study. A minimum...
