Background: Patients diagnosed with superficial bladder cancer who have not undergone total cystectomy are at high risk for recurrence, and bladder surveillance with cystoscopy is recommended for such patients every 3-6 months. We examined the degree to which bladder cancer patients undergo the recommended surveillance procedures and identified patient and primary care provider characteristics associated with nonadherence to these recommendations.
Methods: We used information obtained from the Surveillance, Epidemiology, and End Results (SEER) Program-Medicare-linked database to identify 6717 patients aged 65 years or older who were diagnosed with superficial bladder cancer from 1992 through 1996 and who survived for at least 3 years after diagnosis but did not have a total cystectomy.
Background: Although there is no proven benefit associated with screening for lung cancer, screening programs are attracting many individuals who perceive themselves to be at high risk due to smoking. We sought to determine whether the risk of lung cancer varies predictably among smokers.
Methods: We used data on 18 172 subjects enrolled in the Carotene and Retinol Efficacy Trial (CARET)-a large, randomized trial of lung cancer prevention-to derive a lung cancer risk prediction model.
Objectives: To examine the association of total energy intake and macronutrient contributors to energy with prostate cancer risk among men in the Baltimore Longitudinal Study of Aging.
Methods: In the Baltimore Longitudinal Study of Aging cohort, 444 men completed at least one food frequency questionnaire (FFQ). At their earliest FFQ completion, men were 45 to 92 years old.
Objective: To investigate the association between prostate cancer and calcium and other nutrients thought to influence the synthesis of 1,25-dihydroxyvitamin D [1,25(OH)2D].
Methods: We included in the analysis 454 male participants in the Baltimore Longitudinal Study of Aging who were 46 to 92 years old at the time of completion of a food frequency questionnaire. Among them, 69 men were diagnosed with prostate cancer during their lifetime.
