RT Tools

Radiotherapy dose equivalence (EQD2) based on LQ model, BED calculator, NTCP, dose correction for RT interruption, IBR estimation, RPA / DS-GPA score for brain metastases and Partin tables + Roach index calculation for prostate cancer ect..

By Prof. Abdelkarim S. ALLAL, Head of Radiation Oncology Department, HFR-Fribourg, Switzerland. I've designed it for the radiation oncology community and the professionals linked to this speciality.

This is Beta8 version series 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

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.

4) Brain section:

- RPA / DS-GPA class and score calculation as well as median OS for brain metatstases patients. DS- seems to be the more reliable.

5) Varia section:

- It displays the references used in the present app and different professional links. Internet connexion is only required for this section.
