Obesity Increases Prevalence of Colonic Adenomas at Screening Colonoscopy: A Canadian Community-Based Study.

Background And Aims: Obesity is a risk factor for colorectal neoplasia. We examined the influence of obesity and metabolic syndrome (MetS) on prevalence of neoplasia at screening colonoscopy.

Methods: We evaluated 2020 subjects undergoing first screening colonoscopy.

Developing a methodology for three-dimensional correlation of PET-CT images and whole-mount histopathology in non-small-cell lung cancer.

Background: Understanding the three-dimensional (3D) volumetric relationship between imaging and functional or histopathologic heterogeneity of tumours is a key concept in the development of image-guided radiotherapy. Our aim was to develop a methodologic framework to enable the reconstruction of resected lung specimens containing non-small-cell lung cancer (NSCLC), to register the result in 3D with diagnostic imaging, and to import the reconstruction into a radiation treatment planning system.

Methods And Results: We recruited 12 patients for an investigation of radiology-pathology correlation (RPC) in nsclc.

Integrating regional and community lung cancer services to improve patient care.

Lung cancer is the leading cause of cancer death in Canada. The organization of health care services is central to the delivery of accessible, high-quality medical care and may be one factor that influences patient outcome. An exciting opportunity arose for clinicians to initiate the redesign of lung cancer services provided by three institutions in the Greater Toronto Area.

Thyroid thymoma in childhood.

A nontoxic thyroid nodule was detected in a female infant soon after birth. At 4 years of age, the nodule was removed. Histological examination disclosed a Iobulated spindle-cell neoplasm with focal epithelioid differentiation.
