BACKGROUND Associations between socioeconomic status (SES) and the incidence of cancer have been reported previously in the U.S. Canada has more comprehensive health care and social programs than the U.S. The purpose of this study was to compare the strength of associations between SES and cancer incidence in Canada and the U.S. METHODS The regions(More)
PURPOSE To describe the adoption of concurrent cisplatin-based chemoradiotherapy (C-CRT), and to evaluate its impact on the outcome of cervical cancer in Ontario. METHODS We used a population-based cancer registry to identify the 4,069 patients with invasive carcinoma of the cervix diagnosed in Ontario between 1992 and 2001. We linked electronic records(More)
PURPOSE To describe hospital bed utilization in the final 6 months of life in patients dying of cancer in Ontario, Canada. PATIENTS AND METHODS Hospital separation records were linked to a population-based cancer registry to identify factors associated with hospitalization in the 203,713 patients who died of cancer in Ontario between 1986 and 1998.

PURPOSE The objectives of this study were as follows: (1) to compare the magnitude of the association between socioeconomic status (SES) and cancer survival in the Canadian province of Ontario with that in the United States (U.S.), and (2) to compare cancer survival in communities with similar SES in Ontario and in the U.S. METHODS The Ontario Cancer(More)
BACKGROUND AND PURPOSE It is known that the socioeconomic status (SES) of the patient is associated with cancer survival in the United States. The purpose of this study was to determine whether the association between SES and survival is also present in Canada, a society with a comprehensive, universal, health insurance program. METHODS A population-based(More)
BACKGROUND Lower socioeconomic status (SES) is associated with worsened cancer survival. The authors evaluate the impact of SES on stage of cancer at diagnosis and survival in Ontario, Canada. METHODS All incident cases of breast, colon, rectal, nonsmall cell lung, cervical, and laryngeal cancer diagnosed in Ontario during the years 2003-2007 were(More)
OBJECTIVE To describe the variation in the use of radiotherapy (RT) in women in Ontario within 1 year of diagnosis of breast cancer, from 1982 to 1991, and to identify factors associated with these variations. DESIGN Retrospective, population-based cohort study. SETTING Ontario. POPULATION All women registered by the Ontario Cancer Registry (OCR) with(More)
AIMS Determining the appropriate rate of radiotherapy is important for ensuring optimal radiotherapy utilisation and accessibility. A criterion-based benchmark (CBB) was developed for estimating the need for radiotherapy in incident breast cancer cases. Our primary objective was to compare an evidence-based estimate (Ebest) of need against the CBB. These(More)
PURPOSE The purpose of this study was to assess whether: (i) radiotherapy (RT) utilization varies with age in Ontario cancer patients; (ii) age-associated differences in the use of RT (if they exist) vary with cancer site and treatment intent; (iii) the age-associated variation in RT utilization is comparable to the decline in functional status in the(More)
PURPOSE Two previous studies, by Gorey et al. and Boyd et al., compared associations between socioeconomic status (SES) and cancer survival in Canada and the United States. Both studies used SES information from population censuses linked to cancer registries. This study investigates why two similar studies led to apparently conflicting results. METHODS(More)
