Gynae BT_Lucknow_2018

Limitations of the EQD2 model for BT

➢ Chemotherapy is not taken into account

➢ Uncertainty increases for single fraction dose values >7-10Gy

➢ Only cell repair is considered

➢ / values and T

1/2 are under discussion (E.g. tumour type prostate, OAR etc.)

➢ Repopulation not taken into account (while we know that overall treatment time is important)
