Abstract: Objectives: The aim of this study is to demonstrate the efficacy of the modified technique of radical organ-preserving surgery of invasive cervical cancer (CC) in patients of reproductive age. Methods: This study included 118 patients of reproductive age (34.9 ± 4.8 years) with a morphologically verified diagnosis of invasive CC (T1a-1bNxM0). All patients underwent organ-preserving surgery in the scope of radical trachelectomy. A shape memory mesh implant woven in the form of a stocking from superelastic nickelide titanium thread with subsequent fixation with separate sutures around the perimeter was used to form the uterine closure apparatus and to strengthen the utero-vaginal anastomosis. The mesh implant was made of superelastic thin nickelide titanium threads with a diameter of 60–40 microns on a metal knitting machine. All patients were prospectively followed up for a mean of 120 months. Results: No intraoperative or postoperative complications were revealed when using a shape memory implant made of titanium nickelide during radical trachelectomy to form a locking apparatus and strengthen the anastomosis zone. No cervical stenoses or mesh failures were noted in any case. The 5-year overall and recurrence-free survival rates were 100% and 98%, respectively. Two patients indicated recurrence; it occurred in 3 and 36 months. There were 42 spontaneous pregnancies, and 29 resulted in full-term delivery, whereas 2 and 11 ended in miscarriage and early abortion, respectively. Currently, 18 patients are at different stages of the use of assisted reproductive technologies. Conclusions: The shape memory implant made of titanium nickelide integrates well into the surrounding tissues and successfully imitates the effect of the cervix. The use of this sparing-surgery technique has shown reasonably good results in carrying the pregnancy to term and good reproductive outcomes.
