Conclusion:

Low pre-treatment ADC and high rise of ADC during (chemo)RT were established as significant indicators for favorable LRC in patients with OPC. These findings could allow treatment regimens to be modified according to the patient’s individual risk for recurrence. ΔADC and ADC during RT showed significant differences between HPV+ and HPV- patients. However, since these findings were not confirmed on pretreatment ADC values, DW-MRI parameters currently cannot be reliably used to distinguish between the two clinical entities before start of the treatment.
