Principles and Recommendations for the Provision of Healthcare in Canada to Adolescent and Young Adult-Aged Cancer Patients and Survivors.

Adolescents and young adults (AYA) with cancer and survivors of cancer in childhood, adolescence, and young adulthood are a constituency facing disparities of care affecting quality of life and other outcomes in many parts of the world. In Canada, this situation occurs in a nation with population-based cancer control programs and a government-funded healthcare system. The Canadian Task Force on Adolescents and Young Adults with Cancer was established in 2008 with a mission to ensure that AYA-aged Canadians with cancer and AYA survivors of cancer have prompt, equitable access to the best care, and to establish and support research to identify how their health outcomes and quality of life can be optimized.

Determinants of delays in treatment initiation in children and adolescents diagnosed with leukemia or lymphoma in Canada.

Minimizing delays that may occur along the cancer care pathway requires an understanding of their determinants. Few studies on childhood cancers have been published on the factors that influence the time it takes for patients to get a first medical consultation (patient delay) and treatment (health care system [HCS] delay) once cancer symptoms have been recognized. Our objective was to assess factors related to disease, patient and HCS on patient and HCS delay for children and adolescents with leukemias and lymphomas in Canada.

Delays in diagnosis and treatment among children and adolescents with cancer in Canada.

Background: Few studies have investigated delays in diagnosis and treatment among children and adolescents with cancer, especially from the perspective of an entire country. Detailed understanding of delays along the continuum of cancer patient care is important in order to establish appropriate benchmarks for timely oncological care. Our objective was to characterise the different components of delay in 2,896 Canadian children and adolescents (aged 0-19 years) with cancer that were enrolled in the Treatment and Outcome Surveillance component of the Canadian Childhood Cancer Surveillance and Control Program from 1995 to 2000.

Childhood and adolescent cancer survival: a period analysis of data from the Canadian Cancer Registry.

This study provides up-to-date estimates of childhood and adolescent (ages 0-19) cancer survival in Canada using data from the Canadian Cancer Registry (CCR). Cases were classified according to the third edition of the International Classification of Childhood Cancer classification scheme. Follow-up for vital status was determined through record linkage to the Canadian Mortality Data Base, and from information reported by provincial/territorial cancer registries.

Impact of age and diagnosis on waiting times between important healthcare events among children 0 to 19 years cared for in pediatric units: the Canadian Childhood Cancer Surveillance and Control Program.

Background: The objectives were to describe and compare waiting times to diagnosis and treatment of children and adolescents who accessed pediatric oncology centers in Canada for healthcare, and to assess the effects and relative contributions of age, sex, and diagnosis to waiting times.

Methods: Waiting times were assessed for 2,365 children (0 to 14 y) and 375 adolescents (15 to 19 y) diagnosed with cancer between 1995 and 2000 inclusive and followed by the Treatment and Outcome Surveillance system of the Canadian Children's Cancer Surveillance and Control Program. Differences were assessed using the chi2 test, Fisher exact test, and Wilcoxon test statistic.

Use of health care services by survivors of childhood and adolescent cancer in Canada.

Background: The number of survivors of childhood cancer in Canada is growing. The large majority of survivors experience at least 1 adverse late effect of their cancer therapy, which often becomes more severe and clinically apparent with time. The extent of survivors' use of health services in Canada is unknown, although coordinated, continuous, long-term follow-up care has been recommended by numerous investigators.

The relation between childhood adverse experiences and disability due to mental health problems in a community sample of women.

Objective: The objective of this study was to examine the association between selected childhood adverse experiences and disability due to mental health problems in a community sample of women. Variables of interest included childhood physical and sexual abuse, parental psychiatric and substance abuse history, and sociodemographic factors.

Method: Girls and women (aged 15 to 64 years) from a province-wide community sample (n = 4239) were asked about disability and most childhood adverse experiences through interview; a self-administered questionnaire inquired about child abuse.

The relationship between childhood adverse experiences and disability due to physical health problems in a community sample of women.

The goal of this study was to examine the association of physical and sexual abuse in childhood, poverty, parental substance abuse problems and parental psychiatric problems with disability due to physical health problems in a community sample of women. We included 4,243 women aged 15-64 years from the Ontario Mental Health Supplement in the analysis. The associations were tested by multiple logistic regression.

Waiting times for cancer care in Canadian children: impact of distance, clinical, and demographic factors.

Background: The objective of this study was to evaluate the impact of distance from residence to pediatric oncology centers on waiting times to diagnostic assessment and treatment in Canadian children with cancer.

Procedure: Two thousand three hundred sixteen children (< 15 years of age) captured by the Canadian Childhood Cancer Surveillance and Control Program's (CCCSCP) Treatment and Outcome Surveillance (TOS) system were included in the analysis. The number of days between onset of symptoms and first anti-cancer therapy was compared for those living less than 25, 25-99, and more than 100 kilometers from their treating center.
