    ABSTRACT: To guarantee a better perfusion, the preservation of the uterine arteries during ART has sometimes been performed but has seldom been tested. We share the results of our tests to provoke a potentially different point of view on such uses of ART. Using computed tomography angiography (CTA), we identified the uterine blood supply in patients who underwent ART with uterine artery preserved and sacrificed. We included 26 consecutive post-ART patients from the outpatient service. The uterine arteries were preserved in 16 patients (61.5%) and ligated in 10 patients (38.5%). Out of the 26 patients studied, 17 (65.4%) were supplied by only the ovarian arteries; seven (26.9%) by one uterine artery and the contralateral ovarian artery; and only 2 (7.6%) by the uterine artery supply alone. No recanalization of the ligated uterine artery or other newly formed compensatory circulation was observed. Among the 16 patients who had preserved uterine arteries, only two (12.5%) showed identifiable bilateral uterine arteries, whereas seven (43.6%) had unilateral uterine artery occlusion and another seven (43.6%), bilateral occlusion. We had three obstetric outcomes, two of which came from the ovarian artery supplying group and one from the hybrid supplying group. The ovarian artery became the dominant supplying vessel after ART. The anatomically preserved uterine artery had a 87.5% chance of occlusion after the procedure. Moreover, the contributing uterine artery did not show any functional superiority. Thus, the benefit of preserving the uterine arteries during ART is probably very limited.

    ABSTRACT: Objectives To evaluate the long-term outcomes and risk factors for recurrence after fertility-sparing laparoscopic radical trachelectomy (LRT) in young women with early-stage cervical cancer.Methods Eighty-eight consecutive patients from four tertiary cancer centers in Korea who had attempted fertility-sparing LRT for early-stage cervical cancer were included in this study.ResultsSeventy-nine patients completed LRT. The mean age and tumor size were 31 years (range, 20–40 years) and 1.8 cm (range, 0.4–7 cm), respectively. Twenty-nine patients had a tumor size greater than 2 cm, 22 had deep stromal invasion greater than 50%, and twelve had lymphovascular space invasion. After a median follow-up time of 44 months (range, 3–105 months), nine patients had recurrence and one had died of disease. A tumor size greater than 2 cm (P = 0.039) and a depth of stromal invasion greater than 50% (P = 0.016) were significant risk factors for recurrence.Conclusions This is the largest series on fertility-sparing LRT in young women with early cervical cancer. LRT is a feasible and safe fertility-sparing alternative to radical hysterectomy in these women. A tumor size greater than 2 cm and a depth of stromal invasion greater than 50% were risk factors for recurrence. J. Surg. Oncol. © 2014 Wiley Periodicals, Inc.

    ABSTRACT: The objective of this study was to estimate the reproductive outcome of young women with early-stage cervical cancer who underwent fertility-sparing laparoscopic radical trachelectomy (LRT). We performed a retrospective review of the medical records of patients with early-stage cervical cancer who underwent LRT. Clinicopathological data were obtained from patient medical records, and reproductive outcome data were obtained from patient medical records and telephone interviews. Fifty-five patients who underwent successful LRT were included in this study. The median age of patients was 32 years (range, 22 to 40 years), and the median follow-up time after LRT was 37 months (range, 3 to 105 months). Menstruation resumed in all patients after LRT, with fifty patients (90.9%) and five patients (9.1%) reporting regular and irregular menstruation, respectively. Six patients (10.9%) presented with cervical stenosis, which was manifested by regular but decreased menstrual flow and newly-developed dysmenorrhea. These patients underwent cervical cannulation and dilatation. Eighteen patients (32.7%) attempted to conceive, with six out of 18 patients receiving fertility treatments. Fourteen pregnancies (i.e., four missed abortions, six preterm births and four full-term births) occurred in 10 patients after LRT. Nine out of 10 patients gave birth to 10 healthy babies. The pregnancy rate after LRT was 55.6% (10/18). The spontaneous abortion rate and live birth rate were 28.6% (4/14) and 71.4% (10/14), respectively. The preterm birth rate was 60% (6/10). Pregnancy and live birth rates after LRT were promising; however, the preterm birth rate was relatively high. Cervical stenosis also occurred in a small percentage of patients.
