A straightforward and unified approach is presented for the calculation of the population attributable risk per cent (etiologic fraction) in the general multivariate setting, with emphasis on using data from case-control studies. The summary attributable risk for multiple factors can be estimated, with or without adjustment for other (confounding) risk(More)
OBJECTIVE To compare the respective performance and effectiveness of autologous chondrocyte implantation (ACI) and mosaicplasty at resurfacing local full-thickness chondral defects of the knee. DESIGN Randomized clinical trial. SETTING Multicenter trial at orthopedic clinics and university hospitals conducted from 1997 to 2000. PATIENTS A population(More)
Biallelic germline mutations in the base excision repair gene MYH have been reported in patients with multiple colorectal adenomas and cancer and in sporadic FAP patients not showing a detectable APC germline mutation. In this study, the prevalence of the common Y165C and G382D germline variants of the MYH gene was examined in 70 FAP/AAPC patients with no(More)
One hundred nine patients with hematologic malignancies, undergoing bone marrow transplants (BMT) from unrelated donors, were randomized in 2 consecutive trials to receive or not to receive antithymocyte globulin (ATG) in the conditioning regimen, as follows: (A) 54 patients (median age, 28 years; 39% with advanced disease) were randomized to no ATG (n =(More)
CONTEXT Recently, the implantable cardioverter-defibrillator (ICD) has been promoted for prevention of sudden death in hypertrophic cardiomyopathy (HCM). However, the effectiveness and appropriate selection of patients for this therapy is incompletely resolved. OBJECTIVE To study the relationship between clinical risk profile and incidence and efficacy of(More)
BACKGROUND Procedures to prevent severe graft-versus-host disease (GVHD) delay immune reconstitution secondary to transplants of haploidentical haemopoietic stem cells for the treatment of leukaemia, leading to high rates of late infectious mortality. We aimed to systematically add back genetically engineered donor lymphocytes to facilitate immune(More)
CONTEXT Computed tomographic (CT) colonography has been recognized as an alternative for colorectal cancer (CRC) screening in average-risk individuals, but less information is available on its performance in individuals at increased risk of CRC. OBJECTIVE To assess the accuracy of CT colonography in detecting advanced colorectal neoplasia in asymptomatic(More)
PURPOSE To investigate the activity of letrozole plus/minus oral metronomic cyclophosphamide as primary systemic treatment (PST) in elderly breast cancer patients. METHODS One hundred fourteen consecutive elderly women with T2-4 N0-1 and estrogen receptor-positive breast cancer were randomly assigned to primary letrozole therapy (2.5 mg daily for 6(More)
BACKGROUND Adrenocortical carcinoma is a rare neoplasm characterized by a high risk of recurrence after radical resection. Whether the use of mitotane is beneficial as an adjuvant treatment has been controversial. Our aim was to evaluate the efficacy of adjuvant mitotane in prolonging recurrence-free survival. METHODS We performed a retrospective analysis(More)
PURPOSE Metformin is associated with reduced breast cancer risk in observational studies in patients with diabetes, but clinical evidence for antitumor activity is unclear. The change in Ki-67 between pretreatment biopsy and post-treatment surgical specimen has prognostic value and may predict antitumor activity in breast cancer. PATIENTS AND METHODS(More)
