Aims
The purpose of this survey was to investigate the current opinion among Italian radiation oncologists regarding the non-palliative radiotherapy in ab initio oligometastatic prostate cancer (OMPC) patients.
Methods
A link to complete the survey was sent via e-mail to Italian radiation oncologists on February 2018. It was requested that only one physician per facility completed the survey, and that he/she was dedicated to PC management in his/her daily clinical practice. The questionnaire consisted of 15 questions concerning the management of OMPC.
Results
One hundred and eleven radiation oncologists filled in the questionnaire. The majority of them see ≤ 10 patients affected by OMPC in a year. More than 80% of respondents would perform radiotherapy (RT) to both the prostate and all metastases sites, but mostly up to 2–3 metastases; furthermore, > 80% of physicians would perform RT on both nodal and bone secondary lesions. Most respondents deem a choline- or prostate-specific membrane antigen (PSMA)-positron emission tomography (PET) mandatory before considering a patient affected by OMPC for non-palliative RT. The association of RT with androgen deprivation therapy for at least 12 months would be recommended by > 50% of respondents. In the follow-up phase, the majority would suggest a clinical examination and PSA every 3–6 months and a choline- or PSMA-PET only at biochemical progression. More than 90% of respondents confirmed to be interested in participating in a multicentre study regarding this subject.
Conclusions
This survey investigated the current opinion of Italian radiation oncologists and confirmed their interest in OMPC management.
