PURPOSE To determine whether higher physical activity after prostate cancer (PCa) diagnosis decreases risk of overall and PCa-specific death. PATIENTS AND METHODS We evaluated physical activity in relation to overall and PCa mortality among 2,705 men in the Health Professionals Follow-Up Study diagnosed with nonmetastatic PCa observed from 1990 to 2008.(More)
BACKGROUND Few studies have reported on late declines and long-term health-related quality of life (HRQOL) after prostate cancer (PCa) treatment. OBJECTIVE We assessed long-term HRQOL following various treatments for localized PCa. DESIGN, SETTING, AND PARTICIPANTS This cohort study of HRQOL up to 10 yr after treatment used a prospectively accrued,(More)
BACKGROUND Prostate tumor heterogeneity and biopsy undersampling pose challenges to accurate, individualized risk assessment for men with localized disease. OBJECTIVE To identify and validate a biopsy-based gene expression signature that predicts clinical recurrence, prostate cancer (PCa) death, and adverse pathology. DESIGN, SETTING, AND PARTICIPANTS(More)
Vigorous activity after diagnosis was recently reported to be inversely associated with prostate cancer-specific mortality. However, men with metastatic disease may decrease their activity due to their disease; thus, a causal interpretation is uncertain. We therefore prospectively examined vigorous activity and brisk walking after diagnosis in relation to(More)
Background:Calcium, phosphorus, fructose, and animal protein are hypothesized to be associated with prostate cancer risk, potentially via their influence on 1,25-dihydroxyvitamin D3. We examined these nutrients and overall diet and prostate cancer risk in the Alpha-Tocopherol Beta-Carotene Cancer Prevention Study (ATBC Study). Materials and methods:The ATBC(More)
PURPOSE The goal of three-dimensional (3-D) conformal radiation is to increase the dose delivered to tumor while minimizing dose to surrounding normal brain. Previously it has been shown that even escalated doses of 70 to 80 Gy have failure patterns that are predominantly local. This article describes the failure patterns and survival seen with high-grade(More)
Increasing evidence supports the important role of nutrition in cancer prevention, including prevention of prostate cancer. In this review, we summarize data for some of the most consistently observed dietary associations for prostate cancer incidence, briefly consider possible postdiagnostic effects of nutrition on prostate cancer progression/survival,(More)
Transforming growth factor beta (TGFbeta) is known to exert both positive and negative effects on different stages of tumor formation. Of the TGFbetaisoforms, TGFbeta1 is highly expressed in prostate cancer and leads to tumor promotion and metastasis. Increased expression of TGFbeta1 is associated with more aggressive tumors and poor prognosis. Several(More)
Pancreatic cancer is one of the most devastating and rapidly fatal cancers, yet little is known about the primary cause and prevention of this disease. We conducted a population-based case-control study to investigate the association between vegetables and fruits and pancreatic cancer. Between 1995 and 1999, 532 cases and 1,701 age- and sex-matched controls(More)
BACKGROUND Plasma levels of insulin-like growth factor-I (IGF-I) have been associated with the risk of prostate cancer. However, the association of IGF-I with specific tumor stage and grade at diagnosis, which correlate with risk of recurrence and mortality, has not been studied rigorously. To determine whether plasma levels of IGF-I and its main(More)
