RT Tools

Radiotherapy dose equivalence (EQD2) based on LQ model, BED calculator, NTCP, dose correction for RT interruption, Intra-Breast Recurrence (IBR) estimation, RPA / DS-GPA score for brain metastases, Partin tables & Roach index calculation for prostate cancer and D'Amico risk groups, and a Bayesian calculator for the probability of malignancy (BIMC) in solid solitary pulmonary nodules (SPN), etc.
By Prof. Abdelkarim S. ALLAL, Head of Radiation Oncology Department, HFR-Fribourg, Switzerland. I've designed this app for the radiation oncology community and the professionals linked to this speciality.

Your comments and rating will be appreciated, suggestions or errors reporting are also welcome via e-mail.

This is Beta8 version series (for android version 2.3+) with the following features:

1) Radiobiology section:
- The LQ Mod to calculate the equivalent dose for different external beam radiotherapy schedules using the linear quadratic model.
- The BED (Biologically Effective Dose) calculation for 1 or 2 RT schedules simultaneously.
- The OTT to calculate the additional dose to be considered in case of RT interruption (OTT extension).


- The Normal Tissue Complication Probability (NTCP) models estimated by the QUANTEC

2) Prostate section:
- Partin tables for pathologic stage prediction according to cT stage, Gleason score and iPSA
- Roach's indexes for risk class of lymph node, vesicle involvement and extracapsular invasion for prostate cancer according to the Gleason and iPSA values


- D'Amico risk groups for localized prostate cancer


- Life expectancy for men at selected age according to USA life tables 2008 (all races and origins)

3) Breast section:
- Intra-Breast Recurrence IBR-nomogram to calculate the 10-y probabilty of freedom from recurrence with or without boost RT based on the EORTC 22881-10882 trials (by Erik van Werkhoven et al.).

4) Brain section:
- RPA / DS-GPA class and score calculation as well as median OS for brain metatstases patients. DS-GPA seems to be more reliable.

5) Lung section


- Bayesian calculator for the probability of malignancy (BIMC) in solid solitary pulmonary nodules (SPN) with improving diagnostic accuracy by means of expanded features (by G. A. Soardi & Simone Perandini et al.).

6) Varia + Ref section:
