Obstetric outcomes of patients undergoing total laparoscopic radical trachelectomy for early stage cervical cancer

Pregnancy outcomes following radical trachelectomy for early-stage cervical cancer: A retrospective observational study in the Kanto area, Japan

OBJECTIVE

The authors aimed to investigate the prevalence of pregnancy and obstetric outcomes in patients who underwent radical trachelectomy (RT) for early-stage cervical cancer in the Kanto area, Japan.

METHOD

A survey among 113 perinatal centers affiliated with the Kanto Society of Obstetrics and Gynecology was conducted to investigate their experience in managing pregnancies following RT, between 2010 and 2020. The association between preterm delivery (before 34 gestational weeks) and a midtrimester short cervix (<13 mm) was evaluated.

RESULTS

The authors retrospectively collected maternal and perinatal data from 13 hospitals. There were 135 pregnancies among 115 women following RT. Of the 135 pregnancies, 32 were miscarriages (<12 gestational weeks: n = 22; >12 gestational weeks: n = 10), and 103 were delivered after 22 gestational weeks. The incidences of preterm delivery before 28 and 34 gestational weeks were 8.7% and 30.1%, respectively. A midtrimester short residual cervix was associated with preterm delivery (P = 0.046).

CONCLUSION

Since more than 100 pregnancies were recorded after RT in the Kanto area, many physicians had more opportunities to manage pregnancy after RT. Pregnancy following RT is associated with increased risk of preterm delivery, and midtrimester short residual cervix is a good predictor of preterm delivery.

Reproductive Results in Cancer Survivors after Fertility Sparing Management: The Need for the Standardization of Definitions

In fertility-sparing management (FSM), two different issues can be distinguished: the risk of recurrence/death and the chance of childbearing. Survival is the principal outcome in oncology, and definitions of overall survival and progression-free survival are therefore well defined and widely accepted. The introduction of FSM to clinical practice was determined by the desire of young cancer patients to still have children. Initially, in small groups of patients, any pregnancy and/or childbirth were considered successes. Nowadays, FSM occupies an important place in cancer treatment, with thousands of young women treated successfully. However, in contrast to survival, no definition has been established for evaluating the reproductive outcomes of FSM. This review article evaluates the current pregnancy and birth rates of cancer patients. Differences between fertility-sparing and conservative treatment are analyzed, and improper and confusing interchangeable applications of these terms are pointed out. Additionally, various reasons for choosing FSM as a treatment method-which are not directly related to fertility preservation (treatment mismatch)-are presented. Uniform definitions of reproduction after FSM should be established to enable the comparison of results and facilitate the counseling of patients regarding the chances of reproduction.

The oncological and obstetric results of radical trachelectomy as a fertility-sparing therapy in early-stage cervical cancer patients

Purpose

This study explored the oncological and obstetric results of radical trachelectomy (RT) in early-stage cervical cancer patients.

Methods

A retrospective analysis was conducted the oncological and obstetric results of 23 patients with early cervical cancer (stages IA2–IB3; International Federation of Gynecology and Obstetrics, 2018) who underwent RT in The Maternal and Child Health Care Hospital of Guiyang, China, from October 2004 to September 2018.

Results

23 patients had cervical tumors of the squamous cell carcinoma histological type. All 23 patients retained reproductive function. The mean follow-up time was 112.87 ± 55.75 (36–199) months. The median tumor size was 2.00 ± 1.35 cm (imperceptible to the eyes 5.00 cm). No recurrence was observed in any of the patient cases. Among the patients with a tumor size > 4 cm (up to 5 cm), three patients who wished to preserve fertility accepted RT following neoadjuvant chemotherapy The pregnancy outcomes were as follows: 8 cases (47.06%) out of 17 cases who attempting pregnancy conceived 12 times.First-trimester abortion and the voluntary abandonment of pregnancy occurred in 4 cases (33.33%), respectively, one patient performed deliberate termination at 24 weeks of gestation. Second-trimester abortion occurred in three cases (25.0%) for chorioamnionitis. Premature delivery at 32 weeks occurred in one case (8.33%).

Conclusion

Radical trachelectomy is a safe and effective treatment for women with early-stage cervical cancer preserving fertility biology. Patients with a cervical tumor sized > 4 cm can be pregnant after neoadjuvant chemotherapy and RT. Accordingly, this treatment is worthy of further exploration.

Fertility-sparing surgery in early-stage cervical cancer: laparoscopic versus abdominal radical trachelectomy

Background

Radical trachelectomy is an acceptable alternative to radical hysterectomy for patients with early-stage cervical cancer who wish to preserve reproductive function. This study is designed to compare the laparoscopic versus abdominal radical trachelectomy and provide oncological and obstetric outcome data on patients who have undergone fertility-sparing surgery.

Methods

We retrospectively analyzed all early-stage cervical cancer patients who underwent abdominal radical trachelectomy (ART) or laparoscopic radical trachelectomy (LRT) between January 2005 and June 2017 in West China Second University Hospital, Sichuan University. Patients' clinical details and follow-up were obtained from hospital records.

Results

A total of 33 patients (5 with IA1, 2 with IA2, and 26 with 1B1) were included, including 18 patients treated with ART and 15 patients treated with LRT. The median age at initial diagnosis was 30.00 ± 4.30 years (range 22–39). The mean follow-up time was 74.67 months. Among the 33 patients, 2 patients (6.06%, 1 abdominal/1 laparoscopic) developed recurrence, and there are no evidence of disease for the remaining 31 patients till now. The overall survival rate 96.99% (32/33). The LRT group had a shorter hospital stay (P = 0.01) and less blood loss (P < 0.01) than the ART group. There is no significant difference in the length of operative time (P = 0.48) between the two surgical routes. Overall, 15/33 patients (45.45%) have tried to conceive. 6 (40.00%) patients were pregnant and 6 (40.00%) patients were infertility. The ART group had a higher clinical pregnancy rate (P = 0.03) than the LRT group.

Conclusions

There is no statistically significant difference in oncological outcome between the two surgical approaches. The clinical pregnancy rate in the ART group was significant higher than that in the LRT group. However, LRT resulted in less blood loss and decreased length of hospital stay.

Round ligament suspension and vaginal purse-string suture: Newly optimized techniques to prevent tumor spillage in laparoscopic radical trachelectomy for cervical cancer

AIM

The purpose of this study was to investigate the surgical techniques and clinical feasibility of nonuterine manipulator and enclosed colpotomy to avoid cancer cell spillages in laparoscopic radical trachelectomy (LRT) for patients with early-stage cervical cancer.

METHODS

We performed the newly optimized surgical techniques of round ligament suspension and vaginal purse-string suture in LRT in 12 patients with early-stage cervical cancer from May 2019 to October 2020. Surgical information and postoperative results were recorded.

RESULTS

All 12 patients successfully underwent LRT with round ligament suspension and vaginal purse-string suture, and no conversion to laparotomy was required. The median operation time was 268.5 min (range 200-320 min), including 5 min of round ligament suspension, and the median blood loss was 20 mL (range 5-50 mL). The median number of pelvic lymph nodes removed was 27 (range 19-35), and median amounts of paracervical tissue was 24 mm (range 21-26 mm) and vaginal tissue was 18 mm (range 16-26 mm). No intraoperative complication or serious postoperative complications were reported.

CONCLUSION

Round ligament suspension and vaginal purse-string suture techniques are feasible and effective in LRT. They can replace uterine manipulator and unprotected colpotomy with satisfactory perioperative outcomes.

Oncologic results of fertility sparing surgery of cervical cancer: An updated systematic review

BACKGROUND

Several techniques can be proposed as fertility sparing surgery in young patients treated for cervical cancer but uncertaincies remain concerning their outcomes. Analysis of oncological issues is then the first aim of this review in order to evaluate the best strategy.

RESULTS

Data were identified from searches of MEDLINE, Current Contents, PubMed and from references in relevant articles from January 1987 to 15th of September 2021. We carry out an updated systematic review involving 5862 patients initially selected for fertility-sparing surgery in 275 series.

FINDINGS

In patients having a stage IB1 disease, recurrence rate/RR in patients undergoing simple conisation/trachelectomy, radical trachelectomy/RT by laparoscopico-vaginal approach, laparotomic or laparoscopic approaches are respectively: 4.1%, 4.7%, 2.4% and 5.2%. In patients having a stage IB2 disease, RR after neoadjuvant chemotherapy or RT by laparotomy are respectively 13.2% and 4.8% (p = .0035). After neoadjuvant treatment a simple cone/trachelectomy was carried out in 91 (30%) patients and a radical one in 210 (70%) cases. But the lowest pregnancy rate is observed in patients undergoing RT by laparotomy (36%).

CONCLUSIONS

The choice between these treatments should be based above all, on objective oncological data that strike a balance for each procedure between the best chances for cure and the fertility results. In patients having a stage IB1 disease, oncological results are quite similar according to the procedure used. In patients having a stage IB2 disease, RT by open approach has the lowest RR. Anyway the lowest pregnancy rate is observed in patients undergoing RT by laparotomy.

Quality of life and long-term clinical outcome following robot-assisted radical trachelectomy

Quality of Life and long-term clinical outcome following robot-assisted radical trachelectomy.

OBJECTIVES

To evaluate quality of life (QoL) and long-term clinical outcome following robot-assisted radical trachelectomy (RRT).

STUDY DESIGN

Prospectively retrieved clinical data were rereviewed on all women planned for a fertility sparing RRT for early stage cervical cancer at Skåne University Hospital, Sweden between 2007 and 2020. QoL was assessed using the validated questionnaires EORTC QLQ-C30, QLQ-CX24 and the Swedish LYMQOL.

RESULTS

Data was analyzed from 49 women, 42 with a finalised RRT and seven with an aborted RRT due to nodal metastases (n = 3) or insufficient margins (n = 4). At a median follow-up time of 54 months one recurrence (2%) occurred (aborted RRT). According to QLQ-C30 the median global health status score was 75. The disease specific QLQ-C24 showed an impact on symptoms related to sexual function where sexual/vaginal functioning had a median score of 25 and 48% of patients reported worry that sex would cause physical pain. Despite this the functional items sexual activity and sexual enjoyment both had a median score of 66.7. Lymphoedema was reported in 45%, where 9% reported severe symptom with an impact on their QoL. No intraoperative complications and no postoperative complications ≥ Clavien Dindo grade III were observed. Twenty-two of 28 (79%) women who attempted to conceive were successful. A metronidazole/no intercourse regimen was applied between GW 15 + 0-21 + 6 in 26 of 28 pregnancies beyond first trimester resulting in a 92% term (≥GW 36 + 0) delivery rate.

CONCLUSIONS

Although robot-assisted radical trachelectomy in this cohort was associated with a low recurrence rate, a high fertility rate and an exceptionally high term delivery rate, women's quality of life was affected postoperatively, particularly with regards to their sexual well-being and lymphatic side-effects.

Current state of fertility preservation for adolescent and young adult patients with gynecological cancer

Although the incidence of the various gynecological cancers has been increasing in recent years, long-term survival is now possible for many patients thanks to advances in multimodality treatment. When treating gynecological cancer in adolescent and young adult (AYA) patients who desire future pregnancy, it is necessary to preserve the reproductive organs and their function to prevent loss of fertility. However, because treatment targets these organs, in the large majority of cases, patients must have these organs removed. In the subfield of oncofertility, treatment of the underlying disease takes priority, and the main principle is preventing delay in treatment. Close cooperation between obstetricians and gynecologists involved in reproductive medicine and oncologists involved in cancer treatment is necessary. In addition, it is important that clinicians work closely not only with other specialists but also with such medical professionals as nurses and counselors so that cancer patients of the AYA generation can be provided the support they need to fight their cancer with hope. Herein, we describe the current status of fertility-sparing therapy for AYA patients with gynecological cancer (cervical cancer, endometrial cancer, or ovarian cancer). In addition, we explain points to keep in mind during a patient's pregnancy after fertility preservation, the latest findings on assisted reproductive technology, and the challenges and prospects of fertility preservation therapy for patients with gynecologic cancer.

Feasibility and Outcomes of "No-Look No-Touch" Laparoscopic Radical Trachelectomy for Early-Stage Cervical Cancer

Intraoperative tumor manipulation and dissemination may compromise the survival of women with early-stage cervical cancer who undergo laparoscopic surgery. This study aimed to examine survival and obstetrical outcomes related to laparoscopic radical trachelectomy (LRT) with a “no-look no-touch” technique in 40 women. This technique incorporates five measures to prevent tumor spillage and damage to the uterine artery perfusion. Five LRTs were aborted because of positive nodes or positive surgical margins. Compared with those of type III laparoscopic radical hysterectomy, the surgical outcomes of LRT in 35 patients were acceptable: operative time (380 min), estimated blood loss (140 mL), length of hospital stay (15 days), and lengths of excised parametrium and vagina. During follow-up (median, 41.3 months), the 5-year disease-free survival and overall survival were 95.0% (95% CI: 69.5–99.3%) and 100%, respectively. Of the nine patients (26%) who attempted pregnancy, seven conceived (nine pregnancies, 76%). Eight were delivered by term cesarean section, while one was miscarried in the first trimester. Our study suggests that the no-look no-touch technique may be effective in reducing the risk of recurrence and improving obstetrical outcomes during LRT for early-stage cervical cancer.

Management of pregnancy after radical trachelectomy

Radical trachelectomy (RT) is a surgery for early-stage cervical cancer treatment that preserves the childbearing ability, and its use has become increasingly common worldwide. Thus, the rate of conception in women who have undergone RT is increasing. However, pregnancy after RT is associated with a higher risk of several obstetric complications such as preterm delivery, preterm premature membrane rupture, and abnormal bleeding from varices at the site of uterovaginal anastomosis. Furthermore, since RT have a residual prophylactic cerclage, it is difficult to manage first- and second-trimester miscarriages. There is little previous data on the management of pregnancy after RT. In this review article, we summarize various management methods and experiences to provide a guide to clinicians for perinatal management after RT.

Fertility-Sparing Surgery in Gynecologic Cancer: A Systematic Review

Fertility-sparing surgery (FSS) is increasingly being offered to women with a gynecological malignancy who wish to preserve fertility. In this systematic review, we evaluate the best evidence currently available on oncological and reproductive outcome after FSS for early stage cervical cancer, epithelial ovarian cancer, and endometrial cancer. An extensive literature search was conducted using the electronic databases Medline (OVID), Embase, and Cochrane Library to identify eligible studies published up to December 2020. In total, 153 studies were included with 7544, 3944, and 1229 patients who underwent FSS for cervical, ovarian, and endometrial cancer, respectively. We assessed the different FSS techniques that are available to preserve fertility, i.e., omitting removal of the uterine body and preserving at least one ovary. Overall, recurrence rates after FSS are reassuring and therefore, these conservative procedures seem oncologically safe in the current selection of patients with low-stage and low-grade disease. However, generalized conclusions should be made with caution due to the methodology of available studies, i.e., mostly retrospective cohort studies with a heterogeneous patient population, inducing selection bias. Moreover, about half of patients do not pursue pregnancy despite FSS and the reasons for these decisions have not yet been well studied. International collaboration will facilitate the collection of solid evidence on FSS and the related decision-making process to optimize patient selection and counseling.

Fertility-Sparing Surgery for Early-Stage Cervical Cancer: A Systematic Review of the Literature

OBJECTIVE

This systematic review aimed to evaluate oncologic and reproductive outcomes after fertility-sparing surgery (FSS) for early-stage cervical cancer (early CC).

DATA SOURCES

Ovid MEDLINE, Ovid EMBASE, and Cochrane CENTRAL were searched from 1980 to the present using Medical Subject Headings terms; other controlled vocabulary terms; and keywords related to fertility, cervical cancer, and surgical techniques.

METHODS OF STUDY SELECTION

A total of 2415 studies were screened, with 53 studies included. Studies reporting recurrences with a median follow-up of 12 months in early CC (International Federation of Gynecology and Obstetrics 2009 stages IA with lymphovascular space invasion, IB, or IIA) of traditional histologic type undergoing FSS were included.

TABULATION, INTEGRATION, AND RESULTS

The studies were grouped by intervention, including vaginal radical trachelectomy (VRT), abdominal radical trachelectomy (ART), minimally invasive radical trachelectomy (MIS-RT), and conization or simple trachelectomy (ST), and studies involving neoadjuvant chemotherapy (NACT). Combined rates of recurrence (RR), cancer death (CDR), pregnancy (PR), and live birth (LBR) were calculated per procedure on the basis of all included studies that reported outcomes on that procedure. The results were as follows: VRT: RR 4%, CDR 1.7%, PR 49.4%, and LBR 65.0% ART: RR 3.9%, CDR 1.4%, PR 43.2%, and LBR 44.0% MIS-RT: RR 4.2%, CDR 0.7%, PR 36.2%, and LBR 57.1% Cone or ST: RR 4.2%, CDR 0.8%, PR 55.1%, and LBR 71.9% NACT: RR 7.5% and CDR 2.0% CONCLUSION: FSS of early CC with VRT, ART, or MIS-RT have comparable oncologic outcomes in carefully selected patients, with reproductive outcomes favoring VRT. Data on nonradical FSS with cone or ST are less robust but support similar oncologic outcomes to radical trachelectomy with fewer reproductive complications. NACT in this setting requires more investigation before routine implementation into practice.

Reproductive and obstetric outcomes after abdominal radical trachelectomy (ART) for patients with early-stage cervical cancers in Fudan, China

OBJECTIVE

To report the reproductive and obstetric outcomes of patients undergoing abdominal radical trachelectomy (ART) for the treatment of early-stage cervical cancers in Fudan, China.

METHODS

We retrospectively reviewed a prospectively collected database of 360 patients with stage IA1-IB1 cervical cancers who underwent ART between 2004 and 2018.

RESULTS

Overall, 211 women (58.6%) did not plan to get pregnant immediately after ART, and 89.6% of them were due to childbearing before surgery or unmarried. Among 149 women who attempted to conceive, 26 (17.4%) of them achieved 30 pregnancies. Eighty-six patients (57.7%) had infertility problems, 44 attempted to conceive with assisted reproductive technologies, and 12 (27.3%) succeeded. Post-operative cervical stenosis (26, 27.4%) and fallopian tube obstruction (22, 23.2%) were the most common reasons for infertility after surgery. Among the patients who conceived, there were 3 first-trimester miscarriages, 6 second-trimester miscarriages, and 2 elective terminations. A total of 19 pregnancies reached the third trimester, and 84.2% of them ended after 36 weeks. Twelve of 20 cases in patients with cerclage placed had full-term birth, while 3 of 5 patients without cerclage placed suffered from second-trimester miscarriage or preterm birth.

CONCLUSIONS

Immediately after ART, many patients were reluctant to conceive, while others suffered from cervical stenosis or fallopian tube obstruction, which had led to low pregnancy rate. Pregnant patients might experience miscarriage or preterm labor which could be prevented by cervical cerclage. Assisted reproductive technology should be encouraged to improve obstetric outcomes.

Reproductive counseling and pregnancy outcomes after radical trachelectomy for early stage cervical cancer

Objective

To evaluate patient perceptions of preoperative reproductive counseling and to evaluate complications and pregnancy outcomes in women who had radical trachelectomy (RT) for early stage cervical cancer.

Methods

Patients who underwent RT from January 1, 2004, through July 31, 2017, and had been cancer free for more than 1 year after RT were eligible; consented patients were sent a 16-item online survey.

Results

Of the 58 eligible patients, 39 patients (67%) completed the questionnaire. Eighteen patients (46%) reported receiving reproductive counseling and 26 (68%) reported receiving counseling about pregnancy risks and complications prior to RT, mainly delivered by gynecologic oncologists. Twenty-nine patients (74%) reported having a complication after RT, and cervical stenosis was the most common complication, occurring in 13 patients (33%). Twenty-four patients actively attempted to conceive after RT, and 20 pregnancies were achieved in 13 patients for a pregnancy rate of 54%. Eight pregnancies were spontaneous and 12 required a fertility treatment. There were 5 spontaneous first-trimester miscarriages; 14 of the 20 pregnancies (70%) resulted in live births. The median time to conception was 13.5 months (range, 1–120).

Conclusion

A significant proportion of women with early stage cervical cancer do not receive adequate reproductive counseling before RT, and many women undergoing RT experience complications that can negatively impact their fertility. We recommend a preoperative consultation with a reproductive endocrinologist for all patients considering RT.

Trachelectomy for reproductive-aged women with early-stage cervical cancer: minimally invasive surgery versus laparotomy

BACKGROUND

A recent trial demonstrated decreased survival in women with early-stage cervical cancer who underwent radical hysterectomy via minimally invasive surgery compared with laparotomy; however, outcomes following trachelectomy have yet to be studied.

OBJECTIVE

To examine trends, characteristics, and survival of reproductive-aged women with early-stage cervical cancer who underwent minimally invasive trachelectomy.

STUDY DESIGN

This is a retrospective study examining the National Cancer Database between 2010 and 2015. Women aged <50 years who underwent trachelectomy for stage IA2-IB cervical cancer were grouped by mode of surgery. Clinicopathologic characteristics and outcomes were compared between minimally invasive surgery and laparotomy groups.

RESULTS

A total of 246 women were included, 144 (58.5%, 95% confidence interval, 52.4%-64.7%) of whom had trachelectomy with a minimally invasive surgery approach. Median age was similar between the minimally invasive surgery and laparotomy groups (median, 31 vs 29 years, P = .20). There was a significant increase in the use of minimally invasive surgery from 29.3% in 2010 to 75.0% in 2015 (P < .001). Specifically, minimally invasive surgery became the dominant approach for trachelectomy by year 2011 (54.8%). Hospitals registered in the West (75.0% vs 25.0%) were more likely, whereas those registered in the Midwest (46.9% vs 53.1%) were less likely, to perform minimally invasive surgery (P = .02). Median follow-up was 37 months (interquartile range, 23-51) for the minimally invasive surgery group and 40 months (interquartile range, 26-67) for the laparotomy group. During follow-up, there were 11 (5.3%) deaths, 4 (3.5%) in the minimally invasive surgery group and 7 (7.6%) in the laparotomy group (P = .25).

CONCLUSION

Minimally invasive surgery has become the dominant modality for trachelectomy in reproductive-aged women with stage IA2-IB cervical cancer after year 2011. Survival of women with stage IA2-IB cervical cancer who underwent trachelectomy is generally good regardless of surgical modality. Although our study showed no difference in survival between the minimally invasive surgery and laparotomy approaches, effects of MIS on survival remain unknown and further study is warranted.

MRI measurement of residual cervical length after radical trachelectomy for cervical cancer and the risk of adverse pregnancy outcomes: a blinded imaging analysis

OBJECTIVE

To determine the association between the residual cervix measured on postoperative MRI after radical vaginal trachelectomy (RVT) and adverse obstetrical outcomes.

DESIGN

Observational study.

SETTING

Referral Cancer centre.

POPULATION

Women who conceived after RVT for cervical cancer at the Royal Marsden Hospital, London, between 1995 and 2015.

METHODS

Postoperative MRI scans were analysed by three researchers. The agreement between researchers was assessed by Pearson's correlation coefficient and Bland-Altman plot. Patients were divided into two groups (<10 and ≥10 mm residual cervix) for the analysis of adverse obstetrical outcomes.

MAIN OUTCOME MEASURES

Late miscarriage, premature delivery, premature rupture of membranes (PROM) and chorioamnionitis.

RESULTS

Thirty-one MRI scans were available; 29 of these women had a pregnancy that progressed beyond the first trimester. There was a strong reproducibility of the measurement of residual cervix (P < 0.001). Nineteen women (65.5%) had <10 mm residual cervix and 10 (34.5%) had ≥10 mm. Among women with <10 mm residual cervix, seven (36.8%) experienced PROM and ten (66.7%) had a preterm birth; No women with ≥10 mm residual cervix had PROM and two (22.2%) had a preterm birth (P = 0.028 and P = 0.035, respectively). Overall, there were nine (16.7%) first-trimester miscarriages, six (11.1%) late fetal losses, 12 (31.6%) preterm births and 36 (66.7%) live births. After a mean follow up of 78.1 months, 36 women were disease-free and one woman had died.

CONCLUSIONS

MRI measurements of the residual cervix are reproducible between observers. The incidence of PROM and premature delivery is higher when the residual cervix after RVT is <10 mm.

TWEETABLE ABSTRACT

The risk of prematurity after RVT can be predicted from measurements of residual cervical length on postoperative MRI scan.

Oncologic and obstetrical outcomes with fertility-sparing treatment of cervical cancer: a systematic review and meta-analysis

OBJECTIVE

The objectives of this study were to evaluate the rates of recurrence, survival and pregnancy, and characterize pregnancy outcomes of early-stage cervical cancer(eCC) treated with fertility-sparing methods such as cervical conization (CON) and radical trachelectomy(RT) with or without pelvic lymphadenectomy.

STUDY DESIGN

This was a meta-analysis of observational studies analyzed by a random-effects model and a meta-regression to assess heterogeneity.

RESULTS

Sixty observational studies encompassing 2,854 patients were included; 17 of which evaluated CON and 43 RT. Three hundred and seventy-five patients were included in the CON group: 176(46.9%) stage IA1 and 167(44.5%) stage IB1. In the RT group, 2479 cases were included: 143(6.0%) stage IA1, 299(12.1%) stage IA2, 1987(79.9%) stage IB1. CON was performed in 347(92.5%) cases, resulting in a recurrence rate of 0.4%(95%CI: 0.0%-1.4%), a death rate of 0%(0%-0%), a pregnancy rate of 36.1%(26.4%-46.2%), a spontaneous abortion rate of 14.8%(9.3%-21.2%) and a preterm delivery rate of 6.8%(1.5%-15.5%). For the RT group, 2273(91.7%) underwent successful surgeries with a recurrence rate of 2.3%(1.3%-3.4%),a death rate of 0.7%(0.3%-1.1%), a pregnancy rate of 20.5%(16.8%-24.5%), a spontaneous abortion rate of 24.0%(18.8%-29.6%) and a preterm delivery rate of 26.6%(19.6%-34.2%). From a subgroup analysis, the recurrence rates for stage IA tumors treated with CON and RT were 0.4%(0.0%-1.9%) and 0.7%(0.0%-2.3%), respectively; and for stage IB were 0.6%(0.0%-2.7%) and 2.3%(0.9%-4.1%).

CONCLUSION

Fertility-sparing treatment including CON or RT for eCC is feasible and carefully selected women can preserve fertility and achieve pregnancy resulting in live births. CON seems to result in better pregnancy outcomes than RT with similar rates of recurrence and mortality.

Abdominal scar characteristics as a predictor of cervical stenosis after abdominal radical trachelectomy

To investigate whether abdominal scar characteristics could predict the occurrence of cervical stenosis after abdominal radical trachelectomy (ART), we conducted a retrospective study and investigated the relationship between abdominal scar characteristics and the occurrence of cervical stenosis in patients one year after undergoing ART. The abdominal scars were evaluated using the Vancouver Scar Scale (VSS). Seventy-two participants were enrolled in the study, including 15 (20.8%) women with cervical stenosis, and 57 (79.2%) without stenosis. Results showed that the mean abdominal scar score assessed by VSS was higher in patients with cervical stenosis (7, range: 1-10) compared to those without stenosis (4, range: 0-9) (P = 0.001). Incidence rates of cervical stenosis increased with the VSS score. For women with VSS scores of 0 to 4, 5, 6, 7, 8, 9 and 10, respectively, the occurrences of cervical stenosis were 6.1%, 16.7%, 16.7%, 27.3%, 37.5%, 50% and 100%. The cutoff point of VSS score was 7 according to the receiver operating characteristic (ROC) curve. Fourteen of the 15 stenosis happened either in patients without anti-stenosis tools (Foley catheters or tailed intrauterine devices) placed during the surgery or after the devices were removed. Our results demonstrated that VSS is an effective approach to assess the presence of cervical stenosis after ART. Women who have an abdominal scar with a VSS score > 7 have a high risk of developing isthmic stenosis without anti-stenosis tools in place.

Closure of the cervical os in patients after fertility preserving treatment for early cervical cancer - results of a prospective observational study

INTRODUCTION

Up to 50% of the infants delivered after radical vaginal trachelectomy (RVT) are born prematurely. An effective strategy to reduce this number could be the closure of the cervical os (CCO).

PATIENTS AND METHODS

Fifteen pregnant patients who had a RVT due to early cervical cancer were included in this prospective case control study. All patients were scheduled for CCO early in the second trimester. CCO was performed in 12 patients. Their data were compared to data from 125 pregnancies after a RVT without CCO.

RESULTS

The patients who had CCO were compared to patients without CCO. One patient had an early rupture of the amniotic membranes prior to CCO. Two patients chose not to undergo CCO. In 12 patients CCO was performed without complications. There was no early preterm delivery in the CCO group as compared to a rate of 5% in 125 pregnancies in the non-CCO group.

DISCUSSION

We developed a protocol to reduce the risk of preterm deliveries after a RVT. Digital examinations should be avoided. Vaginal checks for pH can discover ascending infections - the main cause of preterm deliveries after a RVT. Infections should be treated adequately. CCO can further reduce the risk of preterm deliveries after a RVT.

Role of robotic surgery in cervical malignancy

Surgical treatment is the mainstay of the management of early-stage cervical cancer. Abdominal radical hysterectomy and trachelectomy have long been the standard surgical approach to early-stage cervical cancer, achieving excellent survival outcomes. Recently, laparoscopic radical hysterectomy and trachelectomy have become the preferred alternative to abdominal surgery because laparoscopic approaches lead to better surgical outcomes without compromising survival outcomes. Since the robotic surgery platform was approved for the use of gynaecologic surgery in 2005, robotic radical hysterectomy and trachelectomy have been increasingly used in the surgical management of early-stage cervical cancer. However, the role of robotic surgery is poorly defined. This review examines the role of robotic surgery in the surgical management of cervical cancer by comparing the published data on its use with those of abdominal and laparoscopic surgeries.

Mid-trimester residual cervical length and the risk of preterm birth in pregnancies after abdominal radical trachelectomy: a retrospective analysis

OBJECTIVE

To investigate the association between mid-trimester residual cervical length (CL) and the risk of preterm birth in pregnancies after abdominal radical trachelectomy (RT).

DESIGN

Retrospective cohort study.

SETTING

University hospital.

POPULATION

A total of 33 deliveries after 22 weeks' gestation in 30 women who underwent abdominal RT including prophylactic cervical cerclage and perinatal care between January 2002 and May 2016.

METHODS

The association between mid-trimester residual CL (the distance between the cerclage and the external cervical os) and gestational age at delivery was investigated. Receiver-operating characteristics (ROC) curve analysis was performed to estimate the optimal cut-off values of the mid-trimester residual CL for the prediction of preterm birth.

MAIN OUTCOME MEASURES

Preterm birth before 34 weeks' gestation.

RESULTS

Mid-trimester residual CL showed a significant correlation with gestational age at delivery (r = 0.36, P < 0.05). There was a significant difference in residual CL between women who did and those who did not give birth before 34 weeks (P < 0.05). Mid-trimester residual CL < 13 mm was a good predictor of birth before 34 weeks, with a sensitivity of 67%, specificity of 75%, positive predictive value of 55% and negative predictive value of 86% (area under ROC curve, 0.75).

CONCLUSIONS

Mid-trimester residual CL is significantly correlated with gestational age at delivery. Residual CL assessment could be used to reassure physicians and women that there is only a small chance of preterm birth in pregnancies after abdominal RT.

TWEETABLE ABSTRACT

Mid-trimester residual cervical length is a good predictor of preterm birth after radical trachelectomy.

Menstrual pattern after abdominal radical trachelectomy

To assess changes of menstrual patterns, their causes, preventions and treatment methods after abdominal radical trachelectomy (ART), we recorded patients’ menstrual patterns after surgery and compared them with the conditions before surgery. Patients were divided into 3 groups based on their menstrual status post-trachelectomy:Group 1: menstrual patterns unchanged; Group 2: menstrual patterns changed without amenorrhea; and Group 3: amenorrhea. One hundred and twenty-nine patients were included: 39 (30.2%) women belonged to Group 1, 74 (57.4%) to Group 2 and 16 (12.4%) to Group 3. For patients in Group 2, the most common presenting symptom was decrease of menstrual volume (59, 79.7%), followed by a prolonged (33, 44.6%) menstrual bleeding. All of the changes in Group 2 and 12 cases in Group 3 were due to narrow of the remaining cervical os. Additionally, 9 and 12 patients, respectively, in Group 2 and 3, developed cervical stenosis. To maintain regular menstruation and prevent isthmic stenosis, 99 patients had tailed intrauterine devices (IUDs) placed in the uterine cavity. Incidence of cervical stenosis all happened in patients without IUDs placed in the uterine cavity. Menstrual condition improved in all patients except one after dilation of the new-cervix. Our results demonstrated that the majority of patients suffered from changes in menstrual patterns after ART. Narrowing of the remaining cervical canal was the main reason and could be treated by cervical dilation. The use of a tailed IUD was effective in the prevention of this complication.

What is the impact of preconception abdominal cerclage on fertility: evidence from a randomized controlled trial

INTRODUCTION

There is documented concern that cerclage may cause cervical stenosis or changes to the cervical mucus, which may reduce fertility. The aim of this study is to determine whether placement of a preconception abdominal cerclage affects fertility.

MATERIAL AND METHODS

This was a planned subgroup analysis of a randomized controlled trial comparing abdominal cerclage, high vaginal cerclage or low vaginal cerclage. Women with a history of previous second-trimester miscarriage or preterm birth despite having a low vaginal cerclage, presenting to specialist preterm birth services in the UK, were eligible for inclusion. Only women randomized before conception were included in this analysis. Women randomized to abdominal cerclage had the surgery performed before conception (abdominal group). Women randomized to high or low transvaginal cerclage received it in the subsequent pregnancy (control group).

RESULTS

Abdominal cerclage was performed in 19 women and transvaginal cerclage in 48 women. Overall, there was no statistically significant difference between time to conception between the two groups (hazard ratio 1.34; 95% confidence interval 0.72-2.50, p = 0.35). Rates of conception at 6, 12, and 18 months were similar - 37% in abdominal group vs. 35% in control group at 6 months (relative risk 1.04; 95% confidence interval 0.52-2.10; p = 0.91); 58% in abdominal group vs. 42% in control group at 12 months (relative risk 1.39; 95% confidence interval 0.84-2.31, p = 0.21); 74% in abdominal group vs. 56% in control group at 18 months (relative risk 1.31; 95% confidence interval 0.91-1.89; p = 0.15).

CONCLUSION

This subgroup analysis of randomized data indicates that abdominal cerclage does not affect fertility rates.

Pregnancy Outcomes After Abdominal Radical Trachelectomy for Early-Stage Cervical Cancer: A 13-Year Experience in a Single Tertiary-Care Center

OBJECTIVE

To investigate pregnancy outcomes in women after abdominal radical trachelectomy (RT) for early-stage cervical cancer.

METHODS

The patients' background, fertility, and pregnancy outcomes were reviewed in a total of 61 pregnancies in 48 of 172 women who underwent abdominal RT at Keio University Hospital between September 2002 and December 2013.

RESULTS

There were 5 women with stage IA1, 2 with stage IA2, and 41 with stage IB1. Histological types were as follows: squamous cell carcinoma (n = 36), adenocarcinoma (n = 10), and adenosquamous cell carcinoma (n = 2). The pregnancy rate of women attempting to conceive after abdominal RT was 44% (48/109). The mean ± SD duration from abdominal RT to conception was 3.1 ± 1.9 years. Of 61 pregnancies, 42 pregnancies were achieved by fertility treatment (in vitro fertilization-embryo transfer, 39; intrauterine insemination, 3). After excluding one pregnancy without detailed clinical information, there were 42 live births (5 in 22-27 weeks, 11 in 28-33weeks, 20 in 34-36 weeks, and 6 in 37-38 weeks), 13 miscarriages, and 5 ongoing pregnancies. While there were 10 first trimester miscarriages, 3 pregnancies ended in the second trimester owing to chorioamnionitis. The mean gestational age at birth was 33 weeks of pregnancy. Thirty-seven neonates were appropriate-for-date, and one was small-for-date. Six pregnancies exhibited massive bleeding from the residual cervix in the late pregnancy. Preterm birth less than 34 weeks of pregnancy was related to premature rupture of the membrane (P < 0.05). Chorioamnionitis was evident in 9 of 11 pregnancies with preterm premature rupture of the membrane followed by birth at less than 34 weeks of pregnancy. No parturients exhibited lochiometra and endometritis postpartum.

CONCLUSIONS

Abdominal RT provided favorable pregnancy outcomes, and fertility treatment could be advantageous to conception. Massive bleeding from the residual cervix as well as ascending infection might be characteristic features during pregnancy after abdominal RT.

Fertility-sparing surgery for uterine cervical cancer

The standard treatment for early cervical cancer of the uterus (CC) is radical hysterectomy with resection of the parametrium and pelvic lymphadenectomy. At least 40% of patients develop early-stage CC during child-bearing age, therefore preserving the uterus to maintain fertility has been an important consideration. Several surgical procedures including conization and vaginal or abdominal radical trachelectomy have been reported. These procedures are safe for removing lymph node negative CC tumors with <2 cm diameter. Recently, less radical surgical procedures that maintain fertility, such as conization, simple trachelectomy, minimally invasive surgery and neoadjuvant chemotherapy, have been indicated for tumors greater than 2 cm in diameter. In this review, we discuss the currently accepted surgical approaches for treating CC while maintaining fertility.

Fertility preservation in women with cervical, endometrial or ovarian cancers

Background

Although cancer in general affects an aged population, a significant number of women develop cancer at childbearing age. Long-term survival rates after gynecological cancer, especially in young patients are increasing and all quality-of-life aspects, including preservation of fertility have become of major relevance.

Outcomes

Surgical techniques aimed at sparing reproductive organs and preserving fertility have been developed for women presenting with gynecological cancer found at early stages. Indications for fertility-sparing surgery are in general restricted to women presenting with a well-differentiated low-grade tumor in its early stages or with low malignant potential. Up to now, use of fertility-sparing techniques in well-selected patients has not been shown to affect overall survival negatively and fertility outcomes reported have been favorable. Still larger amounts of data and longer follow-up periods are needed. Several current fertility-sparing cancer treatments may result in sub-fertility and in those cases assisted reproductive techniques are indicated. Overall quality of life has been satisfactory in cancer patients after fertility-sparing surgery.

Conclusions

Fertility-sparing surgery is a viable tool to enable gynecological cancer patients of young age to fulfill their family building without impairment of oncological outcome. Cancer patients of reproductive age should undergo fertility counseling to analyze this sensitive subject. Further studies are needed to investigate the role of fertility-sparing treatment and combined adjuvant therapy in higher-grade cancers.

Deliveries After Malignant Disease Before Pregnancy: Maternal Characteristics, Pregnancy, and Delivery Complications

PURPOSE

Survival after cancer has increased, and the question of risks in later pregnancies has become important. A previous malignancy may affect pregnancy outcome.

METHODS

Comparison of women with malignant disease before pregnancy with all other women giving birth during 1994-2011. Data were obtained by linkage between Swedish national health registers. Subfertility, evaluated as time to pregnancy, and in vitro fertilization (IVF) before the relevant delivery were studied. The following delivery diagnoses were studied: gestational diabetes, preeclampsia, placenta previa, placenta abruption, placenta retention, bleeding around delivery, and premature rupture of membranes. The rates of cesarean section and vacuum extraction or forceps delivery were also studied.

RESULTS

We identified 3931 women with 7176 deliveries and with a malignancy diagnosed at least 1 year before the delivery. The total number of deliveries in Sweden in these years was 1,746,870. Overall, an increased risk of subfertility (odds ratio [OR] 1.17, 95% confidence interval [CI] 1.07-1.28), use of IVF (OR = 1.36, CI 1.21-1.53), delivery complications (OR = 1.17, 95% CI 1.10-1.24), and rate of caesarean sections (OR = 1.27, 95% CI 1.20-1.34) was observed among women with a history of malignancy compared with other women.

CONCLUSION

We found an increased risk of subfertility, pregnancy, and delivery complications in women with a history of malignant disease. Further studies are needed to evaluate the risks of specific treatments and to provide these women with reliable information that could affect their family planning.

Reproductive and oncologic outcome following robot-assisted laparoscopic radical trachelectomy for early stage cervical cancer

OBJECTIVE

To investigate the reproductive and oncologic outcome following robotic radical trachelectomy for early stage cervical cancer.

METHODS

All women with early stage cervical cancer planned for fertility-sparing robotic trachelectomy between December 2007 and April 2015 at two tertiary referral centers in Sweden were identified. Perioperative- and follow-up data was retrieved from prospective databases used for all robotic procedures at the respective institution and an additional review of computerized patient files was performed. Reproductive outcome evaluation was restricted to women with ≥12months follow-up and an active wish to conceive. Oncological outcome was evaluated for all patients.

RESULTS

Fifty-six women (3 stage IA1, 14 stage IA2 and 39 stage IB1) were included. The median age was 29years (range 23-41). Median follow-up was 24months (range 1-89). Seven trachelectomies were aborted in favor of a radical hysterectomy and/or chemoradiation due to nodal metastases or insufficient margins; two distant recurrences occurred in these women. A local recurrence was seen in two of the 49 women (4%) in whom the procedure was completed as planned. Seventeen of the 21 women (81%) in the reproductive follow-up group conceived - 16 naturally and one following IVF. Sixteen women (94%) delivered in the third trimester, 12 women (71%) in gestational week ≥36. One (6%) second trimester delivery occurred.

CONCLUSION

The high fertility rate, low rate of premature deliveries and an acceptable rate of recurrence support the feasibility of robotic fertility-sparing radical trachelectomy in women with early stage cervical cancer.

[Laparoscopic radical trachelectomy for preservation of fertility in early cervical cancer. A case report]

BACKGROUND

Radical hysterectomy is the standard treatment for patients with early-stage cervical cancer. However, for women who wish to preserve fertility, radical trachelectomy is a safe and viable option.

OBJECTIVE

To present the first case of laparoscopic radical trachelectomy performed in the National Cancer Institute, and published in Mexico.

CLINICAL CASE

Patient, 34 years old, gravid 1, caesarean 1, stage IB1 cervical cancer, squamous, wishing to preserve fertility. She underwent a laparoscopic radical trachelectomy and bilateral dissection of the pelvic lymph nodes. Operation time was 330minutes, and the estimated blood loss was 100ml. There were no intraoperative or postoperative complications. The final pathology reported a tumour of 15mm with infiltration of 7mm, surgical margins without injury, and pelvic nodes without tumour. After a 12 month follow-up, the patient is having regular periods, but has not yet tried to get pregnant. No evidence of recurrence.

CONCLUSIONS

Laparoscopic radical trachelectomy and bilateral pelvic lymphadenectomy is a safe alternative in young patients who wish to preserve fertility with early stage cervical cancer.

Radical Vaginal Trachelectomy with Laparoscopic Pelvic Lymphadenectomy for Fertility Preservation in Young Women with Early-Stage Cervical Cancer

The primary objective of this study was to describe our experience with the conservative treatment of early-stage cervical cancer (stages IA1, IA2, and IB1) with radical vaginal trachelectomy (RVT) and laparoscopic pelvic lymphadenectomy. This retrospective observational case series included 36 patients with early cervical cancer. Radical trachelectomy and laparoscopic pelvic lymphadenectomy were performed as described by D. Dargent in 32 of these cases. Oncologic, reproductive, and obstetric outcomes were observed subsequently over a median period of 42 (24-96) weeks. A total of 32 RVTs were preformed with a mean operating time of 117 ± 22.8 (77-167) minutes and an average blood loss of 486 mL (150-800 mL). All obtained resection margins were negative for cancer. Lymphovascular space invasion was noted in 11 (30.55 %) of the cases. No recurrences occurred during the study period. Seven (17.8 %) patients were able to become pregnant postoperatively, five of whom delivered healthy infants near term. Radical vaginal trachelectomy with laparoscopic pelvic lymphadenectomy appears to be a safe therapeutic option for fertility preservation in young women with early cervical cancer.

The surgical management of cervical cancer: an overview and literature review

IMPORTANCE

Surgery has evolved into the standard therapy for nonbulky carcinoma of the cervix. The mainstay of surgical management is radical hysterectomy; however, less radical procedures have a small but important role in the management of cervical tumors.

OBJECTIVE

Our objective was to discuss the literature behind the different procedures utilized in the management of cervical cancer, emphasizing the radical hysterectomy. In addition, we aimed to discuss ongoing trials looking at the utility of less radical surgeries as well as emerging technologies in the management of this disease.

EVIDENCE ACQUISITION

We performed a PubMed literature search for articles in the English language that pertained to the topic of surgical techniques and their outcomes in the treatment of cervical cancer.

RESULTS

The minimally invasive approaches to radical hysterectomy appear to reduce morbidity without affecting oncological outcomes, although further data are needed looking at long-term outcomes with the robotic platform. Trials are currently ongoing looking at the role of less radical surgery for patients with low-risk disease and the feasibility of sentinel lymph node mapping.

CONCLUSIONS AND RELEVANCE

Radical hysterectomy with pelvic lymphadenectomy has evolved into the standard therapy for nonbulky disease, and there is a clear advantage in the use of minimally invasive techniques to perform these procedures. However, pending ongoing trials, less radical surgery in patients with low-risk invasive disease as well as sentinel lymph node mapping may emerge as standards of care in selected patients with cervical carcinoma.

Notch1 ligand signaling pathway activated in cervical cancer: poor prognosis with high-level JAG1/Notch1

OBJECTIVE

Notch signalings are regulated multiple cellular processes during cancer progression. We aimed to investigate the significance and prognostic value of expression of Notch1 and JAG1 in cervical cancer to determine whether they could serve as prognostic predictors.

METHODS/MATERIALS

The expression of Notch1/JAGD1 was investigated by real-time PCR, western blot assay and its association with overall survival of patients was analyzed by statistical analysis.

RESULTS

Notch1 and JAGD1 expression level were significantly elevated in cervical cancer in comparison to normal specimens and other types of Notch receptors and ligands. It is also proved that Notch1 and JAGD1 expression were to be associated with cervical cancer invasion, lymph node metastasis, and FIGO system. In addition, survival analysis proved that elevated Notch1 and JAGD1 expression were associated with poor overall survival of patients (P = 0.01, P = 0.02 log-rank test), respectively.

CONCLUSIONS

The present data proved the over-expression of Notch1/JAGD1 and its association with tumor progression in human cervical cancer, which might be a potential valuable biomarker for cervical cancer and further studies need.
