Purpose/Objective:

External beam radiotherapy (EBRT) with concurrent chemotherapy followed by a brachytherapy (BT) boost is the standard of care for patients with locally advanced cervical cancer (LACC). Image-guided brachytherapy (IGBT) has been shown to improve local control rates and decrease toxicity employing hybrid intracavitary/interstitial applicators that offer better tumor coverage. BT is NOT optional and is the gold standard in the treatment of these patients, accepted as such by the European Society of Gynecological Oncology (ESGO), the European Society of Oncological Radiotherapy (ESTRO) and the European Society of Pathology (ESP) (1-3). In daily clinical practice, however, a certain proportion of patients are ineligible for IGBT or refuse it. With the aim to know the current status in Spanish radiotherapy departments of this clinical problem, a national survey was designed on behalf of the Spanish group of gynecological tumors (GINECOR) of the Spanish Society of Radiation Oncology (SEOR) between all the members of the group.

Material/Methods:

An online survey was conducted in March 2023 to 95 members of GINECOR of 58 radiotherapy departments with 4 items questionnaire. Specific topic referred to the last 3 years of activity (March 2020-March 2023) addressed were: number of patients with LACC treated with EBRT and BT, number of patients in whom BT could not be performed, reasons for not performing BT and number of applications that could not be carried out (none of those planned or only some of those planned).
