Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To investigate whether optimal irradiation and indicated lateral lymph node dissections (LLNDs) can reduce the lateral local recurrence rate to 6%, as described in the literature. Patients who cannot undergo nerve sparing LLND or minimally invasive TME due to the extensiveness of their tumor will drop out of the main cohort and enter the registration arm together with Asian patients treated in Asia who follow the exact same protocol. | — |
Secondary
| Measure | Time frame |
|---|---|
| To evaluate the morbidity, quality of life and functional quality of patients by questionnaires. | — |
