Patient progress modelling and results in Wilm's Tumour

The report describes the development of a mathematical model of the progress of patients with Wilm's Tumour using the methodology developed by Jackson & Aspden [1, 2]. The model incorporates two prognostic factors which are shown to influence patient progress. These are the stage of the tumour and the age of the patient at presentation. The model proved adequate to represent an initial set of patient data, and comparison runs were performed with data from a later time period. These runs highlighted changes in patient progress between the two groups and illustrated the usefulness of the model in this type of analysis. The analysis also underlined the poor prognosis of patients over 5 years old who relapsed.

An approach to the treatment evaluation of Hodgkin's disease

Hodgkin's disease is a cancer of the lymphatic system. The major feature influencing the type of treatment employed, and the ultimate prognosis, is the stage or extent of disease prior to therapy. This paper is concerned with evaluating the difference in patient progress of two staging procedures. One (pathological staging) procedure is more extensive than the other (clinical staging). The evaluation is carried out by firstly developing a mathematical model of patient progress for pathologically staged patients and then using this model to predict what would have happened to clinically staged patients if they had been treated according to their pathological stage. Comparison of these predictions with actual results suggests that pathologically staged patients appear to remain in disease free survival (remission) following radio-therapy longer than clinically staged patients.
