Objective: The aim of our study was to evaluate clinical and pathological data in order to draweligibility criteria for oncologically sufficient radical trachelectomy (RT) in early-stage cervical cancer. Reviewing all cases of attempted RT performed at our unit, we focused attention on prognostic indicators of the need for additional oncologic treatment following RT. The analysiswas extended by extensive literature review to include previously published cases of oncologic failures. Methods: The authors retrospectively analyzed data of patients who underwent RT at the Department of Obstetrics and Gynecology, University of Debrecen. Electronic records and case notes of RT cases were reviewed to determine the incidence of abdominal and vaginal route, distribution of clinicopathologic data, and follow-up results of individual cases. Individual procedures were categorized as oncologically insufficient if additional oncologic treatment was necessary following RT. Theoretical eligibility criteria for RT in early-stage cervical cancer were determined retrospectively by selecting prognostic features that were associated with oncologic insufficiency from clinicopathologic indicators of the complete series. Results: Twenty-four cases of RT were performed by the authors, 15 vaginal RTs with laparoscopic pelvic lymphadenectomy and 9 abdominal RTs with open pelvic lymphadenectomy. Fifteen of 24 cases proved oncologically sufficient. Three cases required immediate conversion to radical hysterectomy because of positive sentinel nodes and/or positive isthmic disc on frozen section. In further 5 cases, final pathology results indicated additional oncologic treatment, that is, radical hysterectomy (n = 2), chemoradiotherapy (n = 2), or chemotherapy (n = 1). One patient among immediately converted cases and another 3 among those who required additional oncologic treatment died of their disease later. There were no other cases of recurrences over a median follow-up of 34 months (range, 12Y188 months). Factors that may predict oncologic insufficiency of RTwere stage IB1 or greater, tumor size of greater than 2 cm in 1 dimension or greater than 15mmin 3 dimensions, G3, nonsquamous/adeno histological type, stromal invasion of greater than 9 mm, and lymphovascular space involvement in the primary tumor. Conclusions: Most cases of oncologically insufficient RTs have significant risk features that can be identified preoperatively. There is a need for more clinicopathologic data on oncologic failure of RT cases in order to improve patient selection.
