Prostate cancer-specific suvival differences between radical prostatectomy and curative radiotherapy

DEGROOT, JULIE 26 September 2009 (has links)
Background: The relative treatment effectiveness of surgery versus radiotherapy for early-stage prostate cancer is uncertain and randomized clinical trials are unlikely to be performed. This study describes the difference in cause-specific survival between patients treated with radiotherapy versus surgery, using a number of design and analytic steps to mitigate confounding by indication within an observational study. Methods: We conducted a population-based case-cohort study, sampling patients from the Ontario Cancer Registry who were treated or were candidates for cure by radiotherapy or surgery. Cases were those who died of prostate cancer within 10 years. Cause-specific survival was analyzed using Cox-proportional hazard regression, with variance adjustment for the case-cohort sampling. Analysis using intent to treat was compared to that using treatment received. Propensity scores were also calculated and Cox-proportional hazard regression was conducted within each propensity score quintile. We formed instrumental variable groups based on radiotherapy rates in Cancer Care Ontario Regions (CCORs) using the study population sampling frame and checked the instrumental variable assumption of equal distribution of covariates by comparing those covariates across these groups using data from the subcohort. Results: The adjusted hazard ratios for risk of prostate cancer death for radiotherapy compared to surgery were 1.44 (95% CI 0.86-2.40) and 1.84 (1.06-3.17) using intent to treat and treatment received respectively. Stratified hazard ratios comparing radiotherapy to surgery for death from prostate cancer from the lowest propensity quintile to the highest propensity quintile were 0.30 (0.04-2.28), 1.54 (0.35-6.77), 0.90 (0.29-2.82), 2.71 (1.01-7.31) and 1.08 (0.41-2.81). Differences among these hazard ratios were not statistically significant (p=0.13). The distributions of all prognostic indicators were statistically significantly different between instrumental variable groups. Conclusion: Analysis by intent to treat produced a hazard ratio closer to the null than analysis by treatment received, indicating that uncontrolled confounding toward more serious cases getting radiotherapy was present in the analysis by treatment received. Future studies should focus on obtaining enough numbers for subgroup analysis such as the stratification by risk groups. Caution should be used when using the instrumental variable approach in this population, as prognostic indicators were not as equally distributed as expected. / Thesis (Master, Community Health & Epidemiology) -- Queen's University, 2009-09-24 17:54:09.955

An Exploration of Life Expectancy Calculation Methods to Aid in Prostate Cancer Screening and Treatment Decision-Making

WYKES, Wykes, Dylan 08 April 2011 (has links)
Background: Life expectancy (LE) estimation is an important part of both screening and treatment decision-making for potentially curable prostate cancer. Clinicians’ estimation of patient life expectancy is typically made using population-based life tables and intuition and it is often inaccurate. This study explores methods to improve LE prediction by formally considering patient co-morbid illness status, in addition to age, in the development of a LE prediction tool. Methods: We conducted a population-based retrospective cohort study of patients from the Ontario Cancer Registry who were curative treatment candidates, identified between 1990-1998. We analyzed data on three sub-populations of this cohort, and we used LE estimates from the Ontario Life Tables. Each model utilized Cox proportional hazards analysis, and/or the declining exponential approximation of LE, to estimate the survival experience of potential curative treatment candidates, including the impact due to both age and co-morbid illness status. We developed five separate models, tested them using a random subset of the cohort study sample, and compared their predictive accuracy by measuring both discriminative ability and calibration to determine the ‘best’ model. We also conducted a supplementary analysis using logistic regression to develop a model to predict the probability of 10-year survival. Results: The ‘best’ of our models demonstrated a c-index of 0.65 and very good calibration. Further analysis revealed that our ‘best’ model violated the Cox PH assumption for age and it’s predictions consistently over-estimated observed LE. Supplementary analysis of the logistic regression prediction model demonstrated a c-index of 0.70. Conclusions: Our exploration of methods to predict LE resulted in modest predictive accuracy. However, based on the results of the logistic regression model, we conclude that the results of our LE prediction models are reasonable, and obtaining a high level of predictive accuracy may not be possible given just age and co-morbidities as predictors. Further studies should continue to explore these and other methods for LE prediction. External validation of the ‘best’ model from the current study is required before the model and its accompanying LE reference tables can be recommended for use in a clinical setting for screening or treatment decision-making. / Thesis (Master, Community Health & Epidemiology) -- Queen's University, 2011-04-07 19:11:34.216
