Cervix BT - 2016

Evaluation / Reporting

Level 1 Minimum standard for reporting

HDR Absorbed Dose (Gy) Fraction size (Gy) Number of Fractions Interval between fr. (h)

LDR Absorbed Dose (Gy) Dose Rate (Gy/h) Number of Fractions and Treatment-time

PDR Absorbed Dose (Gy) Pulse size (Gy) Number of pulses, and interval between pulses Number of fractions and interval between fr.

Dose delivery pattern

Source and Dose calculation ( Radionuclide, Source model, Source Strength, Dose calculation algorithm ) Total treatment-time (TT) in hours or days of EBRT, BT and overall TT

Level 2 Advanced standard for reporting

Biological dose reporting

EQD2 values for traget and OAR (endpoints) Respective α/β values* for the target and OAR Respective T1/2 of recovery* Applied recovery model, mono- or bi-exponential

Level 3 Research oriented reporting

EUD or other biologically effective dose model calc. for target and OAR endpoints

TCP or NTCP calculation, with the model explicitly stated

*For the moment - advise to follow GEC-ESTRO recommendations α/β =3Gy for late Effects in OAR and 10 Gy for tumour response, and T 1/2 of 1.5h for both.
