Summary

Cervical cancer is one of the most common cancers in women and one of the leading causes of death in women worldwide. Pre-cancerous lesions (dysplasias) are detected by the preventive smear test at the gynecologist and can thus contribute to a 100% chance of cure if they are clarified by a colposcopic examination as part of the dysplasia consultation and dysplastic lesions are then surgically removed if necessary (conization).

There are few data in the literature on the influence of the menstrual cycle on the bleeding pattern during and after conization. Hormonal variations during the menstrual cycle affect both the extent of blood flow to reproductive organs and hemostasis. In the follicular phase, there is a decrease in local blood flow in the uterus and pelvic organs and an increase in coagulability. Conversely, in the luteal phase there is an increase in local blood supply and a decrease in coagulability. Therefore, it seems reasonable to perform conization in the follicular phase to possibly reduce the extent and incidence of bleeding and bleeding complications. This assumption is supported by clinical observations. For example, there is evidence from other specialties that selection of the timing of surgery, taking into account the menstrual phase, may influence the risk of bleeding. Another factor of interest in menstruation-based surgical planning is psychological vulnerability, which may also vary with the menstrual cycle. Until now, consideration of the menstrual cycle in surgical planning for conization has not been standard practice and there is no recommendation in this regard in the current S3 guideline of the German Society of Gynecology and Obstetrics.

Therefore, this study now aims to answer the question under prospective randomized conditions whether LLETZ conization performed during the follicular phase results in lower blood loss and higher patient satisfaction and lower anxiety scores compared to LLETZ conization performed during the luteal phase.
