Objective — to evaluate the effectiveness of the clinical introduction of radical trachelectomy as organ-sparing surgery in the treatment of invasive cervical cancer patients planning pregnancy. Subject and methods. In 2005 to 2016, the Oncology Clinic, P.A. Herzen Moscow Oncology Research Institute, attempted to perform radical trachelectomy in 167 reproductive-aged patients (mean age, 32.3±3.7 years) with invasive cervical cancer. This operation is made via laparotomy in 119 patients; vaginal and laparoscopic radical trachelectomy was attempted in 25 and 23 patients, respectively. During these operations, oncology principles and certain staging of surgical intervention were strictly complied with. When the emergency histological examination revealed metastases in the removed lymph nodes or tumor elements in the region where cervix of the uterus had been excised from its body, the scope of the operation was extended to radical hysterectomy. In 2014, the authors introduced their own modification of radical laparoscopic trachelectomy, which consecutively included laparoscopic (pelvic lymphadenectomy, ureteric tunneling, and parametrial tissue resection) and vaginal (colpotomy, cervical resection, and formation of utero-vaginal anastomosis) stages. Results. Emergency histological examination showed that during and after radical trachelectomy, the scope of surgery was extended to radical hysterectomy or an adjuvant therapy with reproductive function loss was performed in 14.4% of cases. There were radical abdominal trachelectomy recurrences in 8.9% of patients, relapse-free survival in 91.1%, and overall survival rate in 95% at a median follow-up of 80 months. After radical vaginal trachelectomy, there were no tumor relapses in the patient group at a median follow-up of 25 months. The relapse-free and overall survival rates were 100%. The group of patients undergoing a laparoscopic radical trachelectomy showed a recurrence in one (5.3%) patients, relapse-free survival in 4.7%, and overall survival in 100% at a median follow-up of 10 months. The following indices of reproductive potential preservation were obtained in the radical abdominal (74%), vaginal (88%), and laparoscopic (72.8%) groups. Conclusion. From the oncologic point of view, radical trachelectomy is an adequate alternative to radical trachelectomy in young female patients planning pregnancy who had a cervical tumor up to 2 cm in diameter. However, the issues concerning the realization of reproductive function require further investigation.
