Abstract

Background. In patients treated for early-stage squamous cell vulvar carcinoma local recurrence is reported in up to 40% after ten years. Knowledge on prognostic factors related to local recurrences should be helpful to select high risk patients and/or to develop strategies to prevent local recurrences.

Objective. This systematic review aims to evaluate the current knowledge on the incidence of local recurrences in vulvar carcinoma related to clinicopathologic and cell biologic variables.

Data sources. Relevant studies were identified by an extensive online electronic search in July 2017.

Study eligibility criteria Studies reporting prognostic factors specific for local recurrences of vulvar carcinoma were included. Study appraisal and synthesis methods. Two review authors independently performed data selection, extraction and assessment of study quality. The risk difference was calculated for each prognostic factor when described in two or more studies.

Results. Twenty-two studies were included; most of all were retrospective and mainly reported pathologic prognostic factors. Our review indicates an estimated annual local recurrence rate of 4% without plateauing. The prognostic relevance for local recurrence of vulvar carcinoma of all analyzed variables remains equivocal, including pathologic tumor free margin distance

Conclusions. Current quality of data on prognostic factors for local recurrences in vulvar carcinoma patients does not allow evidence-based clinical decision making. Further research on prognostic factors, applying state of the art methodology is needed to identify high-risk patients and to develop alternative primary and secondary prevention strategies.
