Предпосылки: лейомиомы – самый распространенный вид опухолей женских половых путей, почти 1/3 гистерэктомий проводятся в связи с лейомиомой.
Цель: оценка эффективности мефипристона для неоадъювантной терапии лейомиомы.
Материалы и методы: 90 женщин репродуктивного возраста с лейомиомой матки рандомизировали в 3 группы: 1-я группа – 30 больных получали мифепристон 50 мг ежедневно в течение 3 мес, 2-я группа – 30 больных получали золадекс 3,76 мг подкожно каждые 28 дней в течение 3 мес, после чего в 1 и 2-й группах проводили лапароскопическую миомэктомию, как и в 3-й группе – 30 больных, не получавших неоадъювантной терапии. В 1 и 2-й группах исследовали влияние терапии на рецепторы к эстрогенам и прогестерону, факторы клеточного роста и ангиогенеза, рецепторы к ним, антигены клеточной пролиферации и ингибиторы апоптоза.
Результаты: на неоадъювантной терапии уменьшились кровотечения, боли, объем матки и доминантных узлов, причем в 1-й группе в большей мере, чем во 2-й, а частота неэффективности терапии (около 10%) была одинаковой в обеих группах. По критерию длительности оперативного вмешательства и объема внутриоперационной кровопотери различий между 1 и 2-й группами не было, но каждая из них была достоверно лучше, чем в 3-й группе. На фоне терапии понижалась экспрессия эстрогеновых и прогестероновых рецепторов, индекс пролиферации и васкуляризация лейомиомы. В 1-й группе дистрофические изменения проявлялись преимущественно нарушением сосудистой проницаемости, а во 2-й – накоплением фиброзной ткани.
Заключение: снижение влияний прогестерона в ходе неоадъювантной терапии сопровождается уменьшением активаторов ангиогенеза, что расширяет возможности выполнения органосохраняющих операций.
Background: leiomyoma – the most common type of female genital tract tumors, almost every third hysterectomy is associated with resection of leiomyoma.
Objective: to evaluate the effecacy of mefipristone in neoadjuvant therapy of leiomyoma (LM).
Materials and methods: ninety nonpregnant women of reproductive age with uterine leiomyomas were enrolled into this study. Patients from Group I (n=30) were administered Mifepristone 50 mg once daily for 3 months, patients from Group II (n=30) were administered Zoladex 3,76 mg subcutaneously every 28 days for 3 months and patients from Group III (n = 30) were not administered any therapy. Laparoscopic myomectomy was performed after 3 months from the initiation of the study in all three groups. Effects of neoadjuvant therapy on estrogen and progesterone receptors, cell growth factors and angiogenesis, as well as associated receptors, antigens of cell proliferation and inhibitors of apoptosis were studied in Groups I and II.
Results: the neoadjuvant therapy reduced bleeding, pain intensity, size of uterus and dominant nodes to a greater extent in Group I, than in Group II, while treatment failure rates of ≈10% were similar in both groups. There were no differences between Groups I and II when it comes to duration of surgeryand intraoperative blood loss, but these two criteria performed significantly better in Groups I and II as compared to Group III. During neoadjuvant treatment decrease of estrogen and progesterone receptors expression, of proliferation index and of LMsvascularization were observed. Degenerative changes manifested predominantly in impaired vascular permeability in Group I, while in Group II -in accumulation of fibrous tissue.
Conclusion: inhibition of progesterone effects in the course of neoadjuvant therapy is accompanied by suppression of angiogenesis activators, which extends the potential for organ-sparing surgery.
