PurposeTo evaluate the practice patterns among centers and physicians worldwide regarding sentinel lymph node biopsies (SLNB) in cervical cancer (CC) patients.MethodA validated 35-item questionnaire regarding SLNB in CC supported by the Gynecologic Cancer Intergroup (GCIG), and sponsored by the North-Eastern German Society of Gynaecologic-Oncology (NOGGO) was sent to all major gynecological cancer societies across the globe for further distribution from October 2015 and continued for a period of 7months.ResultsOne hundred and sixty-one institutions from around the world participated. One hundred and six (66%) of the participants were from university centers and 111 (69%) were gynecologic oncologists. One hundred and fifty-two (97%) performed lymphadenectomy (LNE) and 147 (94%) did so systematically; 97 (60%) used SLNB, due to lower morbidity (73%), reliability (55%) and time-saving (27%). In cases of positive SLNB (pN+), 39% of respondents stopped the operation and sent the patient for chemoradiation (CRT), 45% completed pelvic and paraaortic LNE, whereas 26% went on to perform a radical hysterectomy (RH) and systematic pelvic and paraaortic LNE. In case of negative SLNB (pN0), 39% of institutions still performed a systematic pelvic and paraaortic LNE.ConclusionIn this survey worldwide, SLNB adoption is an encouraging 60%, yet ample differences exist regarding strategy, and to a lower extent the techniques used. Lack of experience is the most common reason SLNB is not performed. Efforts to increase surgical education on SLNB technique and multicenter prospective trials providing evidence-based guidelines are warranted.
