Project description
 
Colorectal cancer (CRC) is the second most frequent solid cancer and the third leading cause of cancer related death. There is tremendous potential to reduce CRC incidence and CRC related death via CRC screening. The evidence for many CRC screening interventions is incomplete and for some highly relevant questions no high-quality data are available. For instance, even though colonoscopy is considered the gold standard for CRC screening, there is no randomized controlled colonoscopy study for CRC screening. Microsimulation is an attractive tool to assess effects of CRC screening on a population. Microsimulation models are used for forming medical policies which allocate billions of dollars to specific CRC screening and surveillance interventions. However, existing tools for CRC microsimulation are currently strictly proprietary, and predictions cannot be independently advanced. Moreover, sensitivity analysis is usually insufficient and the space of uncertainty in basic parameters barely explored. Finally, current microsimulation studies do not provide personalized predictions.

We recently developed the microsimulation tool Colon Modeling Open Source Tool (CMOST) (1). CMOST captures the natural history of CRC via early and advanced adenomas, accounting for gender, age, location within the colon and individual differences in CRC risk and allows simulating screening interventions. Detailed calibration and validation was performed and we continued to develop CMOST with >10,000-fold improvements in speed (CMOST 3.0, re-engineered in C++).

The current PhD project aims to enable CMOST to perform personalized CRC screening and surveillance recommendations, considering the detailed personal history of a given patient including many non-standardized situations. Individual carcinoma risk and co-morbidities will be estimated using published scores. We will simulate an individual history of a patient by mapping the parameter space according to the timing of past colonoscopies, CRC risk and comorbidities. For each situation, we will calculate the optimal time points for the next colonoscopies. Results will be related to data from a CRC screening database. Our results will be available on a webpage and can supplement existing guidelines.

In a separate project, we will further advance the functionality of CMOST. In existing CRC microsimulation studies, for sensitivity analyses basic model parameters are not varied. Taking advantage of the strong performance of CMOST, we will implement sensitivity analysis with a much broader scope by using a family of calibrated models with systematic variation of critical model parameters. This approach will enable a deep understanding of the impact of model assumptions on the outcome (e.g. cost-effectiveness of CRC screening) and provide a realistic margin of error for all predictions. The PhD student will also have the opportunity to participate in additional case studies regarding the application of CMOST (e.g. in Germany or Zimbabwe).
