Outcome Prediction

Treatment Outcome and Toxicity Prediction

Predicting treatment outcome and toxicity is critical to select personalized options for an individual cancer patient. Oncologic outcome data is often imbalanced, thus conventional algorithms based on a single objective such as accuracy during model construction may lead to low sensitivity or specificity.

To overcome the limitation of the current single-objective based predictive models, we propose a multi-objective model that explicitly considers both sensitivity and specificity during model optimization. Combined with an artificial immune-based optimization algorithm, the proposed multi-objective model can obtain a solution that balances sensitivity and specificity. 

We have developed models to predictive distant failure for lung and cervical cancer patients after radiation therapy. Additional systemic therapy for those patients at risk for distant failure may reduce the risk and improve overall survival.

We have also developed deep learning based models to predict toxicity for cervical cancer patients after radiotherapy. Special considerations will be given to those patients at high risk for development of treatment-related toxicity during the treatment planning stage.
