ESTRO SCHOOL

TARGET GROUP

The course is aimed at physicians, medical physicists,

biologists and radiation therapists (RTTs).

COURSE AIM

The aimof this course is tomake the attendees better at

makingmodel-supported decisions. Radiation oncology

probably has the most solid quantitative foundation

amongmedical specialties. As in other specialties, results

of randomised controlled trials form evidence-based

treatment guidelines; but in addition, prognostic and

predictive models provide clinical decision support for

individualisedmanagement of cases. Radiation bioeffect

models of Normal Tissue Complication Probability

(NTCP) and Tumour Control Probability (TCP) have

become much more refined and are increasingly being

validated in independent datasets. While integration of

quantitative estimates of various treatment outcomes

is likely to improve patient care, it is also important to

understand the limitations of model estimates and to be

able to assess the validity or quality of a statistical data

analysis or a mathematical model. Uncritical reliance

on model results may compromise patient safety or

treatment outcome.

LEARNINGOUTCOMES

By the end of this course participants should be able to:

• Broadly describe themost commonly used quantitative

methods in radiation oncology and radiation biology

and the assumptions behind these

• Identify appropriate quantitative methods of analysis

for a given data set

• Critically evaluate modelling results especially with

respect to proper validation and estimates of uncer-

tainties.

COURSE CONTENT

• Models and modelling, hypothesis testing and pa-

rameter estimation, type I and II uncertainties

• Clinical trials and evidence-basedmedicine, phase 0,

I, II, III, and IV trial designs, meta-analysis, clinical

endpoints, survival statistics and the Cox Proportional

Hazards Model

• Statistical modelling and exploratory data analysis,

simple mechanistic models, external and internal va-

lidity of models, bootstrap andMonte Carlomethods,

goodness of fit

• Dose-response models, normal tissue complication

probability (NTCP) and tumour control probability

(TCP) models, modelling combinedmodality therapy,

patient-to-patient variability in response, the line-

ar-quadraticmodel and beyond, generalised equivalent

uniform dose, use of models in treatment planning

• Predictive assays, ROC curves and AUC, sensitivity,

specificity, positive and negative predictive value

• High dimensionality data sets, machine learning,

data mining, over-fitting, training and validation

sets, sample splitting, K-fold validation.

PREREQUISITES

No specific requirements are needed for attending this

course although a broad familiarity with the principles

of cancer medicine and radiation oncology is expected.

TEACHINGMETHODS

The four-day course consists of:

• 27 didactic 45-minute lectures

• 4 half-hour interactive discussion sessions

• A practical exercise (1.25 h)

• An interactive data analysis session (1.25 h)

• A Meet-the-professor session where you can bring-

your-own data analysis project and discuss one-on-one

with faculty members (10-minute time slots, 1.25 h

total time).

METHODS OF ASSESSMENT

• Course evaluation form

• Self-assessment tools are integrated in some of the

discussion sessions.
