Pregnancy outcomes in patients after radical trachelectomy

Reproductive outcomes after fertility-sparing surgery for cervical cancer - results of the multicenter FERTISS study

INTRODUCTION

Fertility-sparing treatment (FST) for patients with cervical cancer intends to achieve oncologic outcomes comparable to those after radical treatment while maximizing reproductive outcomes, including the ability to conceive and minimizing the risk of prematurity.

METHODOLOGY

International multicentre retrospective FERTISS study focused on patients treated with FST analysed timing of FST relative to pregnancy, conception attempts and methods, abortion rates, prophylactic procedures reducing the risk of severe prematurity, pregnancy duration, and delivery mode.

RESULTS

Of the 733 patients treated at 44 centres in 13 countries, 49.7% attempted to conceive during median follow-up of 72 months and 22.6% (166/733) patients achieved a successful pregnancy. Success rate was significantly higher after non-radical surgery (63.2%; 122/193) compared to radical trachelectomy (25.7%; 44/171, p < 0.001). Available perinatological data shows that 89.5% (111/124) of the patients became pregnant naturally. There was no significant difference in the abortion rate in the first pregnancy nor delivery success rates between non-radical and radical procedures patients. Preterm delivery (<38 weeks gestation) occurred more frequently after radical than non-radical procedures (76.5% vs. 57.7%, p = 0.15). Almost all patients (97.3%; 73/75) who underwent regular ultrasound cervicometry in pregnancy with subsequent prophylactic procedures delivered a live fetus, compared to 30.6% (15/49) women without such management, p < 0.001.

CONCLUSION

Patients who underwent non-radical surgery had significantly higher pregnancy rates. Most pregnancies resulted in a viable fetus, but radical trachelectomy led to a higher rate of preterm births in the severe prematurity range. Half of the patients did not attempt pregnancy after FST.

Navigating Fertility Preservation Options in Gynecological Cancers: A Comprehensive Review

(1) Background: Currently, an increasing number of women postpone pregnancy beyond the age of 35. Gynecological cancers affect a significant proportion of women of reproductive age, necessitating the development of fertility preservation methods to fulfill family planning. Consequently, providing treatment options that preserve fertility in women diagnosed with gynecological cancers has become a crucial component of care for survivors. (2) Methods: We conducted an extensive search of relevant scientific publications in PubMed and Embase databases and performed a narrative review, including high-quality peer-reviewed research on fertility after being treated for gynecologic cancers, reporting pregnancy rates, birth rates, and pregnancy outcomes in cancer survivors as well as therapeutic options which partially preserve fertility and methods for obtaining a pregnancy in survivors. (3) Discussion: The medicine practiced today is focused on both treating the neoplasm and preserving the quality of life of the patients, with fertility preservation being an important element of this quality. This leads to an improved quality of life, allowing these women to become mothers even in the seemingly adverse circumstances posed by such a pathology. However, although there are guidelines on female fertility preservation in the context of neoplasms, an analysis shows that physicians do not routinely consider it and do not discuss these options with their patients. (4) Conclusions: Advancements in medicine have led to a better understanding and management of gynecological neoplasms, resulting in increased survival rates. Once the battle against these neoplasms is won, the issue of preserving the quality of life for these women arises, with fertility preservation being an important aspect for women who have not yet fulfilled their family planning desires at the time of diagnosis. It is important for patients to be informed about the available options for fertility preservation and to be encouraged to make informed decisions in collaboration with their medical team. Standardized recommendations for onco-fertility into guidelines should be taken into consideration in the future.

Clinical practice guidelines for cervical cancer: the Korean Society of Gynecologic Oncology guidelines

This fifth revised version of the Korean Society of Gynecologic Oncology practice guidelines for the management of cervical cancer incorporates recent research findings and changes in treatment strategies based on version 4.0 released in 2020. Each key question was developed by focusing on recent notable insights and crucial contemporary issues in the field of cervical cancer. These questions were evaluated for their significance and impact on the current treatment and were finalized through voting by the development committee. The selected key questions were as follows: the efficacy and safety of immune checkpoint inhibitors as first- or second-line treatment for recurrent or metastatic cervical cancer; the oncologic safety of minimally invasive radical hysterectomy in early stage cervical cancer; the efficacy and safety of adjuvant systemic treatment after concurrent chemoradiotherapy in locally advanced cervical cancer; and the oncologic safety of sentinel lymph node mapping compared to pelvic lymph node dissection. The recommendations, directions, and strengths of this guideline were based on systematic reviews and meta-analyses, and were finally confirmed through public hearings and external reviews. In this study, we describe the revised practice guidelines for the management of cervical cancer.

Successful pregnancy with in vitro fertilization after vaginal radical trachelectomy and pelvic lymphadenectomy in stage IB1 cervical cancer

OBJECTIVE

To present a case of successful pregnancy after undergoing vaginal radical trachelectomy (VRT) and pelvic lymph node dissection (PLND) for early-stage cervical cancer.

CASE REPORT

A 37-year-old female patient has been diagnosed with stage IB1 cervical cancer and underwent VRT and PLND. Two years after the surgery, the patient successfully conceived and delivered a healthy baby through a cesarean section.

CONCLUSION

This case report demonstrates that pregnancy after VRT and PLND for stage IB1 cervical cancer is possible and can result in a successful outcome. This report provides valuable information for patients and physicians who are considering these surgical options.

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.

The Current Trend of Fertility Preservation in Patients with Cervical Cancer

Although the incidence of most cancers increases with age, a considerable number of patients receive a diagnosis of cancer during their reproductive years. Young women wishing to get pregnant after cancer treatment should be provided consultation for fertility preservation and possible options. In patients with cervical cancer, hysterectomy is often inevitable because the uterus is located too close to the cervix. For young patients with cervical cancer who desire to get pregnant and whose lesion is confined to the cervix, sparing the uterus and, partially, the cervix should be prioritized as much as possible, while simultaneously ensuring favorable oncologic outcomes. In this review, we explore how to choose an adequate fertility-preserving procedure to achieve a balance between favorable oncologic outcomes and fertility and management during pregnancy after a radical trachelectomy in women with early-stage cervical cancer. For patients who require hysterectomy or radiation, evaluation of the ovarian condition and laparoscopic ovarian transposition followed by the use of artificial reproduction techniques and pregnancy by surrogacy should be discussed as options to achieve a successful pregnancy.

Twenty years of experience with less radical fertility-sparing surgery in early-stage cervical cancer: Pregnancy outcomes

INTRODUCTION

The standard procedure in cervical cancer is radical hysterectomy and pelvic lymphadenectomy (PLND). Because of the increasing age of women bearing children, fertility has become a major challenge. We present pregnancy results after less radical fertility-sparing surgery in women with IA1, LVSI positive, IA2 and IB1 (<2 cm, infiltration less than half of the cervical stroma).

MATERIALS AND METHOD

All women (n = 91) underwent laparoscopic sentinel lymph node mapping with frozen section followed by PLND and "selective parametrectomy" (removal of afferent lymphatic channels from the paracervix) if sentinel nodes (SLN) are negative. If lymph nodes were verified negative by definitive histopathology, patients were treated by simple trachelectomy (IB1) or large cone (IA1/IA2) biopsy 1 week after primary surgery.

RESULTS

From 1999 to 2018, 91 women were enrolled in the study (median age 29.1 years, range 21-40). Fertility was spared in 76 (83.5%) women; 13 (17.1%) women did not plan future pregnancy and 63 (82.9%) had pregnancy desires. Fifty-four of 63 women conceived (pregnancy rate 85.7%) and 48 of 63 delivered 58 babies (delivery rate 76.2%). Thirty-nine women delivered in term (67.2%): 13 women between 32 and 36 + 6 weeks of pregnancy, 3 between 28 and 31 + 6 weeks and 3 between 24 and 27 + 6 weeks. Only one woman still plans pregnancy. One woman is currently pregnant.

CONCLUSION

The goal of fertility-sparing surgery is to produce good oncological results and promising pregnancy outcomes. Pregnancy results after less radical fertility-sparing procedures show promise (pregnancy rate 82.9% and delivery rate 76.2%).

Reproductive and Obstetric Outcomes after Fertility-Sparing Treatments for Cervical Cancer: Current Approach and Future Directions

Cervical cancer is one of the leading causes of cancer-related death in women of reproductive age. The established fertility-sparing approaches for the management of early-stage cervical cancer for women who plan pregnancy are associated with a decline in fecundity and an increased risk of pregnancy complications. This article aims to offer an overview of fertility-sparing approaches and the management of potential subfertility and pregnancy complications after these treatments. An extensive search for the available data about infertility and cervical cancer, fertility-sparing techniques in patients with cervical cancer, fertility treatment, obstetrical complications, and pregnancy outcomes in cervical cancer patients was completed. Fertility-preserving procedures such as loop electrosurgical excision procedure (LEEP), cold-knife conization, and trachelectomy in women diagnosed with cervical cancer can be considered as safe and effective treatments that preserve reproductive potential. Current fertility-preserving procedures, based on the balance of the oncological characteristics of patients as well as their desire for reproduction, allow one to obtain acceptable reproductive and obstetric outcomes in women treated for cervical cancer. Nevertheless, careful monitoring of pregnancies obtained after fertility-preserving procedures is recommended, since this cohort of patients should be considered at higher risk compared with a healthy population.

Pregnancy outcomes in children, adolescents, and young adults that survived cancer: A nationwide survey in Japan

AIM

Recent advances in cancer treatment have improved the prognosis of child, adolescent, and young adult (CAYA) cancer survivors. This study aimed to examine the current status of pregnancy outcomes among female cancer survivors in Japan.

METHODS

The first questionnaire was sent to 633 major tertiary institutions certified by the Japan Society of Obstetrics and Gynecology to identify institutions managing cases of pregnant cancer survivors between January 2011 and December 2015. The second questionnaire was sent only to institutions with pregnant cancer survivors during the study period.

RESULTS

We analyzed 2242 singleton deliveries of cancer survivors based on the responses received in the second questionnaire (199/255 responses; 78.0%). The three most frequent types of malignant tumors were uterine cervical (23.4%), breast (17.6%), and thyroid cancers (17.5%). Conception was aided by the use of assisted reproductive technology in 17.0% of the patients. The proportions of mothers aged 35-39.9 and ≥ 40 years were 36.5% and 11.8%, respectively. The prevalence of preterm birth (PTB) at <37, <34, and < 32 weeks' gestation were 16.7%, 6.8%, and 4.3%, respectively. The proportion of infants with low birth weight (LBW) was 18.9%.

CONCLUSION

The present study findings suggest that advanced maternal age was common among pregnant cancer survivors and these survivors often gave birth to PTB and LBW infants in Japan. The likelihood of adverse pregnancy outcomes should be considered by healthcare providers when planning counseling and perinatal care for cancer survivors.

Radical vaginal trachelectomy

Radical vaginal trachelectomy (RVT) is the oldest fertility-sparing procedure for stage 1b cervical cancer. For that reason, there are more published data for RVT than for all the other radical trachelectomy approaches. However, there are no randomised controlled studies between RVT and radical hysterectomy proving the comparability of survival and no randomised controlled studies comparing a vaginal approach with open, standard laparoscopy and robotic approaches. This article intends to describe the case selection, the procedure and outcomes for RVT.

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.

Expectant management for early pregnancy miscarriage after radical trachelectomy: A single hospital-based study

INTRODUCTION

Women who have undergone radical trachelectomy as a fertility-sparing treatment for early-stage cervical cancer may be at higher risk for retained tissues after early-term miscarriage due to cervical cerclage or cervical necrosis. Dilatation and curettage or aspiration may present additional risks in these women. The aim of this study was to assess the efficacy of expectant management for early pregnancy miscarriage after radical trachelectomy.

MATERIAL AND METHODS

Keio University Hospital records were reviewed for women who conceived after abdominal radical trachelectomy and received perinatal care between 1 April 2012 and 31 March 2020. A total of 62 women (76 pregnancies) were identified, and 13 of these women experienced miscarriage before 12 gestational weeks. The management and outcome of these cases were reviewed in detail.

RESULTS

The median maternal age at miscarriage was 39 years (range 31-42 years) and the median duration from abdominal radical trachelectomy to conception was 2.60 years (range 0.49-7.30 years). Cervical necrosis before conception occurred in one case (8%). One patient requested treatment with aspiration and the remaining 12 cases were managed with observation for a median of 23 days (range 7-50 days). There were no cases of endometritis or cases requiring dilatation and curettage for residue tissue. Further, no cases developed laceration of the residual cervix and no loss of cerclage sutures after discharge was noted.

CONCLUSIONS

Expectant management seems to be safe and appropriate for first trimester miscarriage after abdominal radical trachelectomy.

The impact on obstetric outcomes following complete amputation of the cervix uteri in fertility preservation surgery for cervical neoplasm

OBJECTIVES

Radical trachelectomy is offered to women with early-stage cervical neoplasia who desire fertility. The presence of isthmic glands within histological specimens suggests complete cervical amputation and as such, we examined if the presence of these glands in surgical specimens adversely affects obstetric outcomes.

STUDY DESIGN

The study cohort comprises 43 consecutive cases of early-stage cervical neoplasia. The presence of isthmic glands in pathological specimens was correlated with obstetric outcomes. Univariate and multivariate analyses were constructed to identify clinicopathological factors associated with adverse obstetric outcomes.

RESULTS

43 patients underwent fertility sparing surgery; radical (30; 69.8 %) or simple trachelectomy (13; 30.2 %). Of these, 26 (60.5 %) had isthmic glands within the surgical specimen. Isthmic gland presence was not influenced by surgery radicality, disease stage, histological diagnosis, or surgical approach. Obstetric outcomes were available for 36 patients, with 27 attempting conception post-trachelectomy and 15 (55.6 %) achieving at least one pregnancy. Of 21 total pregnancies, the miscarriage and live birth rates were 7.4 % and 85.0 %, respectively. The presence of isthmic glands did not influence the overall conception rate, with 53.8 % of women with complete cervical amputation conceiving compared to 57.1 % of those without (p = 0.8632). Complete removal of the cervix did not increase premature deliveries <37 weeks gestation (p = 0.2521).

CONCLUSIONS

The presence of isthmic glands in trachelectomy specimens provides a reliable surrogate marker for complete cervical amputation. In cases where complete cervical amputation is required to achieve maximum oncological outcomes, patients may be assured that there is little evident impact on fertility and obstetric outcomes.

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 preservation in women with cervical cancer

Fertility preservation in women with cervical cancer is a demanding but evolving issue. Some remarkable achievements have been reached, in particular the improvement of primary and secondary prevention and the broadening of the indications for conservative surgery up to FIGO 2018 stage IB2. Natural pregnancy rate and the rate of obstetrics complications following conservative approach is satisfactory even if not optimal. On the other hand, the use of classic strategies for fertility preservation such as oocytes or ovarian cortex freezing is extremely limited, being the uterus compromised by treatment in a high proportion of cases. In fact, the availability of uterine surrogacy can play a role in the counseling and the decision-making process. The recent advent of uterus transplantation is fascinating but, at present, cannot be viewed as a realistic solution.

Management of pregnancy after fertility-sparing surgery for cervical cancer

Cervical cancer is increasingly diagnosed in women who have not yet completed their reproductive plans. For women with early-stage disease (FIGO stage IA1-IB1), fertility-sparing procedures, such as conization, trachelectomy or radical trachelectomy, represent the treatments of choice. However, women who undergo repeated conization or trachelectomy represent a challenge for obstetricians because they are at increased risk of infertility, mid-trimester miscarriage, preterm premature rupture of membranes and preterm delivery. So far, the evidence-based guidance on the management of these pregnancies is limited. This article reviews the literature discussing pregnancy management in women after fertility-sparing surgery for early cervical cancer. Although the evidence is limited, certain measures are desirable, including screening and treatment of asymptomatic bacteriuria, screening for cervical incompetence and progressive cervical shortening by transvaginal ultrasonography, and fetal fibronectin testing. Vaginal progesterone supplementation should be primary prevention for all women after trachelectomy. Women with a history of preterm delivery or late miscarriage may benefit from cervical cerclage. Elective delivery by cesarean section in the early-term period is desirable.

Multiple management strategies to prolong gestational period after radical trachelectomy

Preterm premature rupture of membranes and massive genital bleeding in the second trimester are serious obstetrical problems in pregnancy after trachelectomy. We had managed a twin post-trachelectomy pregnancy by multiple strategies, and two healthy infants were delivered at 32+5 weeks, although the optimum management for such patients is unknown.

First case of twin pregnancy after vaginal radical trachelectomy in a Japanese woman

Twin pregnancy after radical trachelectomy (RT) for uterine cervical cancer involves an extremely high risk of preterm premature rupture of the membrane (pPROM) and the following occurrence of preterm birth. Herein we report the first case of twin pregnancy after vaginal RT in a Japanese woman. The patient was a 36-year-old nulliparous woman. She became pregnant with twins one year after vaginal RT with laparoscopic lymphadenectomy and the following treatment with the use of in vitro fertilization/embryo transfer. Her pregnancy course was favorable with vaginal disinfection, bed rest, and administration of progesterone, ritodrine, and an ulinastatin vaginal suppository. At 31 weeks + 4 days of pregnancy, a scheduled cesarean section was performed. One baby weighed 1000g, with Apgar scores of 7/8, and the other 1100g, with Apgar scores of 8/9. Her postpartum course was also favorable. The mother remains without evidence of recurrence of the cancer at the time of this report.

Radical Trachelectomy for Early Stage Cervical Cancer

OPINION STATEMENT

In patients with early-stage cervical cancer, radical hysterectomy and pelvic lymphadenectomy is the gold standard. However, this disease commonly affects women of childbearing age; thus an option to spare fertility is ideal. This option came to fruition in the early 90s when the Dargent procedure or radical trachelectomy was first reported. The procedure has subsequently been modified as technology has improved and now may be performed via minimally invasive techniques. Additionally, with the advent of the sentinel lymph node procedure, the morbidity in this usually young patient population has continued to improve. There is a multitude of data to show that oncologic outcomes, concerning recurrence and mortality, are comparable to radical hysterectomy, as well as obstetrical outcomes are favorable. Data to support its acceptance within the gynecologic oncology community has led to radical trachelectomy being implemented into governing body guidelines and should be offered to appropriate candidates with early-stage cervical cancer who wish to preserve fertility.

Successful Pregnancy following Myomectomy Accompanied with Abdominal Radical Trachelectomy for an Infertile Woman with Early Cervical Cancer: A Case Report and Literature Review

Women in the reproductive age group diagnosed with cervical cancer can receive radical trachelectomy in case they wish to preserve fertility. However, the indication for this procedure in infertile women with cervical cancer is controversial depending on the underlying cause of infertility. Here, we present a case of a successful pregnancy following myomectomy accompanied with abdominal radical trachelectomy for an infertile woman with early cervical cancer. The patient was a 38-year-old nulliparous woman with a significant past medical history of infertility of unknown origin. She had been undergoing treatment with assisted reproductive technologies including artificial insemination and in vitro fertilization for over four years. During her treatment for infertility, she was diagnosed with stage IB1 cervical squamous cell carcinoma. She received abdominal radical trachelectomy and abdominal myomectomy in the same surgical procedure. Six months after the surgery, she went for the first embryo transfer and became pregnant. At 26 weeks of pregnancy, a male baby weighing 980 g was delivered with an Apgar score of 3/5/7 by cesarean section due to chorioamnionitis. The baby has received general care in a neonatal intensive care unit for four months and weighed 4520 g when discharged.

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.

Practice guidelines for management of cervical cancer in Korea: a Korean Society of Gynecologic Oncology Consensus Statement

Clinical practice guidelines for gynecologic cancers have been developed by academic society from several countries. Each guideline reflected their own insurance system and unique medical environment, based on the published evidence. The Korean Society of Gynecologic Oncology (KSGO) published the first edition of practice guidelines for gynecologic cancer treatment in late 2006; the second edition was released in July 2010 as an evidence-based recommendation. The Guidelines Revision Committee was established in 2015 and decided to develop the third edition of the guidelines in an advanced format based on evidence-based medicine, embracing up-to-date clinical trials and qualified Korean data. These guidelines cover strategies for diagnosis and treatment of primary and recurrent cervical cancer. The committee members and many gynecologic oncologists derived key questions through discussions, and a number of relevant scientific literature were reviewed in advance. Recommendations for each specific question were developed by the consensus conference, and they are summarized here, along with the details. The objective of these practice guidelines is to establish standard policies on issues in clinical practice related to the management in cervical cancer based on the results in published papers to date and the consensus of experts as a KSGO Consensus Statement.

Fertility-sparing management in cervical cancer: balancing oncologic outcomes with reproductive success

BACKGROUND

Cervical cancer is the fourth most common cancer among women worldwide, many of who are still within their reproductive lifespan. Advances in screening and treatment have increased the 5-year survival for early stage disease to over 90 % in developed countries. The focus is now shifting to reducing morbidity and improving fertility outcomes for cervical cancer patients. Radical trachelectomy with lymph node assessment became the standard of care for selected women with lesions <2 cm who desire fertility preservation. However, several questions still remain regarding the degree of surgical radicality required for tumors <2 cm, and fertility-sparing options for women with early-stage disesase ≥2 cm, and those with more advanced disease. Here, we compile a narrative review of the evidence for oncologic and pregnancy outcomes following radical trachelectomy, non-radical fertility-sparing surgery, and the use of neoadjuvant chemotherapy prior to surgery for larger lesions. We also review the literature for assisted reproductive technologies in women with more advanced disease.

FINDINGS

Available literature suggests that the crude recurrence and mortality rates after radical trachelectomy are <5 and <2 %, respectively (approx. 11 and 4 % for tumors ≥ 2 cm). Among 1238 patients who underwent fertility-sparing surgery for early cervical cancer there were 469 pregnancies with a 67 % live birth rate. Among 134 cases with lesions ≥ 2 cm, there were ten conceptions with a live birth rate of 70 %. Outcomes after non-radical surgery (simple trachelectomy or cervical conization) are similar, although only applicable among a highly selected patient population. For patients ineligible for fertility-preserving surgery or who require adjuvant radiation therapy, current options include ovarian transposition and cryopreservation of oocytes or embryos but other techniques are under investigation.

CONCLUSION

Today, many cervical cancer survivors have successful pregnancies. For those with early-stage disease, minimally invasive and fertility sparing techniques have resulted in improved obstetrical outcomes without compromising oncologic safety. Results from three ongoing trials on non-radical surgery for low-risk tumors <2 cm will further inform the need for radical surgery in such patients. For those in whom natural childbearing is unachievable, advances in assisted reproductive technologies provide reproductive options. Despite our advances, the effects of cervical cancer survivorship on quality of life are not fully elucidated.

Surgical and obstetrical outcomes after laparoscopic radical trachelectomy and pelvic lymphadenectomy for early cervical cancer

Objective

The aim of this study was to evaluate the surgical and obstetrical outcomes of patients with early cervical cancer who underwent laparoscopic radical trachelectomy and pelvic lymphadenectomy.

Methods

We analyzed data from women who underwent laparoscopic radical trachelectomy and pelvic lymphadenectomy between July 2000 and October 2014.

Results

Of a total of 12 patients, 91.7% were FIGO (International Federation of Gynecology and Obstetrics) stages IA2 and IB1. Seven patients (58.3%) had squamous cell carcinoma. The median tumor size was 1.87 cm (range, focal to 4.6 cm) and two patients (16.7%) had a tumor lager than 2 cm. Lymphovascular space invasion in the tumor lesion was reported in six patients (50%). The following surgical complications were observed: neurogenic bladder (one patient), hemoperitoneum (one patient), and infection (one patient). A total of 33.3% had attempted to conceive, resulting in two pregnancies and two healthy babies. All pregnancies were achieved by in vitro fertilization and embryo transfer. Each woman underwent cesarean delivery because of premature pre-labor rupture of membranes at gestational weeks 27.3 and 33.3. After a median follow-up time of 4.4 years (range, 1 to 8 years), there were no recurrences or deaths.

Conclusion

Laparoscopic radical trachelectomy and pelvic lymphadenectomy should be offered as an alternative treatment for women with early stage cervical cancer who want to preserve their fertility.

Perinatal Considerations in Women With Previous Diagnosis of Cancer

As the average age that women have their first child increases and cancer therapies improve survival, obstetricians are more likely to care for pregnant women who have survived cancer. Managing these pregnancies can be challenging, as they may be associated with higher risks of maternal and neonatal morbidity and mortality. Different types of cancer require different types of intervention, including surgery, chemotherapy, radiation, or combinations of these. Prior cancer treatments therefore present different potential complications during pregnancy. Although for most women who survive cancer carrying a pregnancy does not seem to increase mortality rates, there are some associated neonatal morbidities. The most common perinatal complication associated with pregnancy after cancer is prematurity. Women who desire pregnancy after cancer survival should not be discouraged, but appropriate counseling and follow-up should be provided.

Robotic surgery for early stage cervical cancer: Evolution and current trends

The management of early stage cervical cancer often includes surgery in the form of radical hysterectomy, radical trachelectomy, or radical parametrectomy. Surgical techniques have evolved to include minimal invasive approaches, and more recently, to include robotic assisted techniques. This review highlights the evolution of surgical management of early cervical cancer and specifically explores robotic assisted radical hysterectomy, radical trachelectomy, radical parametrectomy, and the role of neoadjuvant chemotherapy.

Assisted reproductive techniques after fertility-sparing treatments in gynaecological cancers

BACKGROUND

The trend toward late childbearing has made fertility preservation a major issue for women who face gynecological cancer. New techniques in assisted reproductive medicine enable conception after primary treatment of these cancers. Here, we aimed to review the efficacy and safety of assisted reproductive techniques (ART) after fertility-preserving treatment of gynaecological cancers.

METHODS

We conducted a systematic literature review of both prospective and retrospective studies in the PubMed, EMBASE, CENTRAL and SciSearch databases. In the retrieved studies, we evaluated live births, clinical pregnancies, overall survival and disease-free survival.

RESULTS

We identified many prospective and retrospective studies on this topic, but no relevant randomized clinical trials. Fertility-sparing treatments with safe oncological outcomes are feasible in endometrial, cervical and ovarian cancer cases. After cancer treatment, ART seem safe and show variable obstetrical outcomes.

CONCLUSIONS

After fertility-preserving treatment for gynaecological cancers, ART can enable pregnancy to be achieved with apparent oncological safety. The success of such procedures should directly impact clinical practice and management of those patients who require fertility-sparing treatment.

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.

Pattern of cancer recurrence in 320 patients after radical vaginal trachelectomy

OBJECTIVE

The oncological outcome regarding disease-free survival and overall survival after radical vaginal trachelectomy (RVT) is the same as the rates after radical hysterectomy. We aim to analyze predictive and risk factors and death in patients with cervical cancer undergoing fertility preservation by laparoscopic lymphadenectomy and RVT.

METHODS

Three hundred twenty patients with cervical cancer underwent RVT between March 1995 and February 2013. In our study, we examined recurrence rates analyzed by risk factors. We classified the presence of lymphovascular space invasion, depth of tumor infiltration, tumor size, and tumor grading as risk factors. The mean follow-up time was 48 months.

RESULTS

Ten of the 320 patients had cancer recurrence. Recurrence appeared at a mean time of 26.1 months (3-108 months) after RVT. Five patients died within 8.8 months (4-15 months) after recurrence was diagnosed. Two of these 5 patients had distant metastasis at the time of recurrence. Five patients were treated successfully by surgery, and 4 patients were treated successfully by chemotherapy. The mean follow-up after the recurrence of these 5 patients is 76 months (6-120 months). None of the 10 patients with recurrences in our series showed significant high-risk factors.

CONCLUSION

There seems to be no pattern in the recurrence of cancer after RVT. It is strictly mandatory to follow up the patients closely every 3 months after RVT to diagnose recurrence at an early stage so therapeutic options such as chemoradiation are still available. Once distant metastasis occurs, prognosis is not good.

Nerve-Sparing Radical Abdominal Trachelectomy Versus Nerve-Sparing Radical Hysterectomy in Early-Stage (FIGO IA2-IB) Cervical Cancer: A Comparative Study on Feasibility and Outcome

Objectives

Standard treatment in early-stage cervical cancer is a radical hysterectomy (RH) with pelvic lymphadenectomy. In women who wish to preserve fertility radical vaginal trachelectomy has been proposed; however, this is not feasible in larger tumors, and nerve-sparing surgery is not possible. Nerve-sparing radical abdominal trachelectomy (NSRAT) overcomes these disadvantages.

Methods

Case-control study of women with early-stage cervical cancer (International Federation of Gynecology and Obstetrics IA2-IB) submitted to NSRAT from 2000 until 2011. Women submitted to nerve-sparing RH with early-stage cervical cancer were included as control subjects.

Results

Twenty-eight patients and 77 control subjects were included. Neoadjuvant chemotherapy was administered in 3 women before NSRAT because the linear extension was or exceeded 40 mm. Local recurrence rate was 3.6% (95% confidence interval [CI], 0.00–10.6) in the NSRAT group compared with 7.8% (95% CI, 1.7–13.9) in the control group (P = 0.44). No significant difference was found between both groups regarding disease-free survival and survival. The overall pregnancy rate was 52.9% (95% CI, 28.7%–77.2%). The mean follow-up was 47.3 months (range, 6–122 months) for NSRAT and 51.8 months (11–129.6 months) for nerve-sparing RH.

Conclusions

Nerve-sparing radical abdominal trachelectomy seems safe and effective in women with early-stage cervical cancer who wish to preserve fertility. Respective women should be informed about this treatment option, especially if the tumor is too large for radical vaginal trachelectomy.

Successful pregnancy by direct intraperitoneal insemination in an infertile patient with failure of recanalization of isthmic stenosis after laparoscopic radical trachelectomy

Radical trachelectomy is a promising fertility-sparing treatment for patients with early stage cervical cancer who want to preserve their fertility. However, isthmic stenosis occurs frequently in patients who received radical trachelectomy and it is one of the causes of infertility following radical trachelectomy. Moreover, despite the treatment for recanalization of isthmic stenosis, recanalization can fail or isthmic stenosis can recur. Herein we report a successful pregnancy and birth by direct intraperitoneal insemination in an infertile woman with failure of recanalization of isthmic stenosis after laparoscopic radical trachelectomy.
