Description:

Number and rate of new cancer cases diagnosed annually from 1992 to the most recent diagnosis year available. Included are all invasive cancers and in situ bladder cancer with cases defined using the Surveillance, Epidemiology and End Results (SEER) Groups for Primary Site based on the World Health Organization International Classification of Diseases for Oncology, Third Edition (ICD-O-3). Random rounding of case counts to the nearest multiple of 5 is used to prevent inappropriate disclosure of health-related information.

Description:

The number of new cases, age-standardized rates and average age at diagnosis of cancers diagnosed annually from 1992 to the most recent diagnosis year available. Included are all invasive cancers and in situ bladder cancer with cases defined using the Surveillance, Epidemiology and End Results (SEER) Groups for Primary Site based on the World Health Organization International Classification of Diseases for Oncology, Third Edition (ICD-O-3). Cancer incidence rates are age-standardized using the direct method and the final 2011 Canadian postcensal population structure. Random rounding of case counts to the nearest multiple of 5 is used to prevent inappropriate disclosure of health-related information.

Description: The validity of survival estimates from cancer registry data depends, in part, on the identification of the deaths of deceased cancer patients. People whose deaths are missed seemingly live on forever and are informally referred to as “immortals”, and their presence in registry data can result in inflated survival estimates. This study assesses the issue of immortals in the Canadian Cancer Registry (CCR) using a recently proposed method that compares the survival of long-term survivors of cancers for which “statistical” cure has been reported with that of similar people from the general population.

Description: Number of deaths caused by neoplasms, by age group and sex, 2000 to most recent year.

Description: According to recent Canadian estimates, over two in five Canadians will likely develop cancer in their lifetime, and one in four is expected to die of it. The lifetime probabilities of developing cancer and dying from cancer are useful summary statistics that describe the impact of cancer within a population. However, there is little information on how lifetime probabilities of developing cancer and dying from cancer have changed over time. This study aims to present detailed lifetime probabilities of developing cancer and dying from cancer by sex and cancer type, and to describe changes in these lifetime probabilities over time among the Canadian population.

Description: Cancer survival estimates provide insights into the effectiveness of early detection and treatment. The stage of cancer at diagnosis is an important determinant of survival, reflecting the extent and spread at the time of disease detection. The recent extension of the Canadian Cancer Registry death-linked analytic file from 2014 to 2017 now offers an opportunity to provide more up-to-date net survival (NS) figures and to profile, for the first time, five-year NS estimates for Canada (excluding Quebec). This study presents five-year stage-specific cancer and five-year NS estimates for the most commonly diagnosed cancers in Canada.

Description:

We consider optimal sampling rates in element-sampling designs when the anticipated analysis is survey-weighted linear regression and the estimands of interest are linear combinations of regression coefficients from one or more models. Methods are first developed assuming that exact design information is available in the sampling frame and then generalized to situations in which some design variables are available only as aggregates for groups of potential subjects, or from inaccurate or old data. We also consider design for estimation of combinations of coefficients from more than one model. A further generalization allows for flexible combinations of coefficients chosen to improve estimation of one effect while controlling for another. Potential applications include estimation of means for several sets of overlapping domains, or improving estimates for subpopulations such as minority races by disproportionate sampling of geographic areas. In the motivating problem of designing a survey on care received by cancer patients (the CanCORS study), potential design information included block-level census data on race/ethnicity and poverty as well as individual-level data. In one study site, an unequal-probability sampling design using the subjectss residential addresses and census data would have reduced the variance of the estimator of an income effect by 25%, or by 38% if the subjects' races were also known. With flexible weighting of the income contrasts by race, the variance of the estimator would be reduced by 26% using residential addresses alone and by 52% using addresses and races. Our methods would be useful in studies in which geographic oversampling by race-ethnicity or socioeconomic characteristics is considered, or in any study in which characteristics available in sampling frames are measured with error.

Description:

This newsletter article presents estimates of the population health impact of cancer in Canada, based on cancer incidence and mortality in 2001. Cancer has a substantial impact in terms of both mortality and morbidity, and a considerable amount of this impact is attributable to modifiable risk factors. These results provide a more comprehensive picture of how cancer affects the Canadian population. This is part of the Population Health Impact of Disease in Canada (PHI) research program.

Description:

Description:

In this Health Reports article, a 20-year trend in the average length of hospital stay for breast cancer is traced, using data from the Hospital Morbitiy Database and the Person-oriented Information Database. Reasons for the shorter length of stay are examined and its impact on outcomes is discussed.

Description:

Cancer surveillance research requires accurate estimates of risk factors at the small area level. These risk factors are often obtained from surveys such as the National Health Interview Survey (NHIS) or the Behavioral Risk Factors Surveillance Survey (BRFSS). Unfortunately, no one population-based survey provides ideal prevalence estimates of such risk factors. One strategy is to combine information from multiple surveys, using the complementary strengths of one survey to compensate for the weakness of the other. The NHIS is a nationally representative, face-to-face survey with a high response rate; however, it cannot produce state or substate estimates of risk factor prevalence because sample sizes are too small. The BRFSS is a state-level telephone survey that excludes non-telephone households and has a lower response rate, but does provide reasonable sample sizes in all states and many counties. Several methods are available for constructing small-area estimators that combine information from both the NHIS and the BRFSS, including direct estimators, estimators under hierarchical Bayes models and model-assisted estimators. In this paper, we focus on the latter, constructing generalized regression (GREG) and 'minimum-distance' estimators and using existing and newly developed small-area smoothing techniques to smooth the resulting estimators.

Description:

Five-year relative survival ratios for prostate and breast cancer rose substantially in the 1985 to 1987 and the 1992 to 1994 periods. Increases in survival ratios for colorectal cancer over the same periods were smaller, but still statistically significant. Relative survival for lung cancer changed little.

Description:

After rising in the early 1990s, prostate cancer incidence rates have fallen. Mortality rates from the disease decreased among men aged 60 or older, but are little changed among younger men. In 2000/01, about four in 10 men aged 40 or older reported having had a prostate-specific antigen (PSA) test.

Description:

This document examines the functional limitations - physical, emotional and social -experienced by patients at the time of diagnosis of cancer and as they undergo various treatments, remission, and palliative and terminal care. These functional limitations are described and classified using the Classification and Measurement System of Functional Health (CLAMES).

These descriptions and classifications are the first step in a new approach to measuring the health of Canadians that examines what factors are adversely affecting population health and how to address them. This document also provides health professionals, advocacy groups, and individual Canadians with an overview of how living with cancer affects day-to-day functioning.
