Associations Between Personal Cancer History and Lung Cancer Risk
MetadataShow full item record
AbstractThe study aim was to investigate the relationship between factors related to personal cancer history and lung cancer risk as well as assess their predictive utility. Characteristics of interest included the number, anatomical site(s), and age of onset of previous cancer(s). Data from the Prostate, Lung, Colorectal and Ovarian Screening (PLCO) Cancer Screening Trial (N = 154,901) and National Lung Screening Trial (N = 53,452) were analysed. Logistic regression models were used to assess the relationships between each variable of interest and 6-year lung cancer risk. Predictive utility was assessed through changes in area-under-the-curve (AUC) after substitution into the PLCOall2014 lung cancer risk prediction model. Previous lung, uterine and oral cancers were strongly and significantly associated with elevated 6-year lung cancer risk after controlling for confounders. None of these refined measures of personal cancer history offered more predictive utility than the simple (yes/no) measure already included in the PLCOall2014 model.

Wellspring: an intrinsic case study of community-based education for adults living with cancer /McGill, Philomena Kathleen Anne.; Department of Graduate and Undergraduate Studies in Education (Brock University, 2006-06-04)This paper presents education research as vital to addressing the issues faced by adults living with cancer. This qualitative study looked at philosophies of practice for cancer patient education. It was about understanding how values and beliefs shape the way program planners and managers operationalize their knowledge of adult education and how this has significant impact on meeting the needs of those touched by cancer. Improved technology has extended life expectancy, so that Canadians living with cancer, or even dying with cancer now spend less time in direct medical care. The notion of cancer as simply a medical concern is outdated. This study found that informational and support needs of adults living with cancer are often unmet, ignored or unknown. This research investigated a community-based education initiative that is inviting, accessible, and promotes a sense of hope. More specifically, this case study uncovered factors contributing to the success of Wellspring, a grass-roots cancer patient support centre which has been recognized nationally for its ability to effectively meet the diverse non-medical supportive care needs of as many cancer patients and caregivers as possible. Therefore, Wellspring was selected as a case study. Educating people to take charge of their own lives and supporting them in making informed decisions about their lifestyle choices made Wellspring part of a social action movement that focused on improving social attitudes toward people living with cancer. Results of this descriptive inquiry and philosophical inquiry evolved into data that was used to devise an organic model of community-based education that encompasses Adler's (1993) four dimensions of philosophy within a socio-cultural context.

Factors affecting treatment decision making for women with breast cancerIrwin, Ellen M.; Department of Graduate and Undergraduate Studies in Education (Brock University, 1994-07-09)This study examined the factors affecting treatment decision making for young women with early stage breast cancer. Thirty women, aged 35 to 52 years, were presented information about two equally effective chemotherapy treatments following surgery for breast cancer using an educational instrument called a "decision board." Although equally effective, the treatments differ with regards to side effects and treatment schedule. The purpose of this research was to investigate what factors affect the decision-making process. Following administration of the decision board, women were given a take-home version to review and asked to return one to two weeks later with a decision, at which time they completed a questionnaire. theoretical framework for this study was constructed from the literature on self-directed learning and critical thinking. The Overall, the factors rated most important to the treatment decision were related to quality of life, side effects, and length of treatment. Five factors were found to be rated significantly different by the women who chose one treatment versus the other in terms of importance to their decision. These were side effects in general, vomiting, hair loss, family role, and the number of trips to the cancer centre required for treatment.Implications and recommendations for patient education, research, and practice evolved from the findings of this study.
