1. A system for predicting medical treatment outcome, the system comprising:
- an input operable to receive values for a plurality of patient specific characteristics of a patient;
a processor operable to apply the values to a first prognosis model, the first prognosis model relating a plurality of variables corresponding to the values to a treatment outcome, the relating being a function of medical knowledge collected from literature and incorporated into the first prognosis model; and
a display operable to output a patient specific prognosis for the patient as a function of the application of the values for the plurality of patient specific characteristics of the patient to the first prognosis model.

Abstract
A predictor of medical treatment outcome is developed and applied. A prognosis model is developed from literature. The model is determined by reverse engineering the literature reported quantities. A relationship of a given variable to a treatment outcome is derived from the literature. A processor may then use individual patient values for one or more variables to predict outcome. The accuracy may be increased by including a data driven model in combination with the literature driven model.

11. In a computer readable storage medium having stored therein data representing instructions executable by a programmed processor for predicting medical treatment outcome, the instructions comprising:
-
applying first and second prognosis models to individual patient information, the first and second prognosis models having different knowledge base sources;
predicting a first treatment outcome with the first prognosis model from the individual patient information and as a function of quantities from clinical study publications as a first knowledge base source; and
predicting a second treatment outcome with the second prognosis model from the individual patient information and as a function of model parameters from a database of past patient information for a plurality of patients as a second knowledge base source. - View Dependent Claims (12, 13, 14)

15. A method for developing a predictor of medical treatment outcome, the method comprising:
-
collecting quantitative medical knowledge of predictors for a disease from literature;
modeling a plurality of univariate relationships between a treatment and the predictors, respectively, from the quantitative medical knowledge;
combining models for the univariate relationships into a multivariate model; and
operating, with a processor, the combined models as a prognosis model for an individual patient as a function of values for the predictors, the values being for the individual patient. - View Dependent Claims (16, 17, 18, 19, 20)
