Our aim was to survey the opinions of Italian radiation and ENT oncologists regarding the role of postoperative radiotherapy (PRT) and the appropriate dose to be given to patients with remnant larynx (RL) after open partial laryngectomy (OPL). The radio-oncologists (RO s) of the Italian Radiation-Oncologist Association (AIRO ) and the ENTs of the Head-Neck Oncology Society (AIOCC-IHNS) were contacted through a SurveyMonkey online interface questionnaire. There were 148 usable responses. The majority of RO s recommended PRT in the case of positive/close margins (R(+)/Rclose) or in the case of initial involvement of thyroid cartilage (pT3tci). In the same cases, ENTs prefer a "watch and wait" policy (w&w). Both disciplines recommended w&w in the case of negative margins (R(-)). Finally, the majority of RO s recommended irradiating RL with 62-66 Gy in R(+), with 56-66 Gy (61.4%) in Rclose and with 56-60 Gy (34%) in pT3tci. In Conclusion, OPL raises new considerations about PRT.
