PG - e038020 LID - 10.1136/bmjopen-2020-038020 [doi] LID - e038020 AB - INTRODUCTION: Recent studies have revealed that the oncological survival outcomes of minimally invasive radical hysterectomy (MIRH) are inferior to those of abdominal radical hysterectomy (ARH) in early-stage cervical cancer, but the potential reasons are unclear. METHODS AND ANALYSIS: Each expert from 28 study centres participating in a previously reported randomised controlled trial (NCT03739944) will provide successive eligible records of at least 100 patients who accepted radical hysterectomy for early-stage cervical cancer between 1 January 2009 and 31 December 2015. Inclusion criteria consist of a definite pathological evaluation of stages IA1 (with positive lymphovascular space invasion), IA2 and IB1 according to the International Federation of Gynecology and Obstetrics 2009 staging system and a histological subtype of squamous cell carcinoma, adenocarcinoma or adenosquamous carcinoma. The primary endpoint is 5-year disease-free survival between the MIRH and ARH groups. The secondary endpoints include the MIRH learning curves of participating surgeons, 5-year overall survival between the MIRH and ARH groups, survival outcomes according to surgical chronology, surgical outcomes and sites of recurrence and potential risk factors that affect survival outcomes. A subgroup analysis in patients with tumour diameter less than 2 cm will follow the similar flow diagram. ETHICS AND DISSEMINATION: This study has been approved by the Institutional Review Board of Peking Union Medical College Hospital (registration no. JS-1711), and is also filed on record by all other 27 centres. The results will be disseminated through community events and peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03738969.
