Open vs minimally invasive radical trachelectomy in early-stage cervical cancer: International Radical Trachelectomy Assessment Study

Surgical, oncologic, and obstetric outcomes of radical trachelectomy in early-stage cervical cancer: results from a retrospective cohort study at Brazil National Cancer Institute

Objective

to analyze oncological, obstetrical, and surgical results of young early-stage cervical cancer patients who underwent radical trachelectomy (RT) surgery and wished to maintain their fertility.

Methodology

a retrospective cohort study was carried out concerning cases attended at the Brazilian National Cancer Institute Gynecology Oncology Service. Patients who underwent RT between January 2005 and January 2021 were included.

Results

A total of 32 patients with median age of 32 years old, 62.5% of whom were nulliparous, were assessed. Concerning cancer type, 65.6% squamous cell carcinoma (SCC) cases, 31.2% adenocarcinoma cases and 3.1% adenosquamous carcinoma cases were verified. Stage IA2 was evidenced in 12.5% of the patients and stage IB < 4 cm in 87.5%. Regarding surgical approaches, 68.25% of the patients underwent vaginal RT (VRT), 18.75%, abdominal RT (ART), 9.3%, the robotic radical trachelectomy (RORT) and 3.1%, video laparoscopy radical trachelectomy (VLRT). The median number of removed lymph nodes was 14, with only two detected as positive. Two cases of positive surgical margins were noted. A total of 3.1% intraoperative and 31.25% postoperative complications were observed, with cervical stenosis being the most common. The recurrence rate of the study was 3.1%, with a median follow-up time of 87 months, where 3.1% deaths occurred. The pregnancy rate of the study was 17.85% (5/28), with 54.5% evolving to live births and 45.5% evolving to abortion.

Conclusion

Radical trachelectomy is a feasible procedure presenting good oncological results and acceptable pregnancy rates.

Robotic-assisted fertility sparing surgery in gynecological oncology

While gynecological malignancies are more commonly diagnosed in elderly women, a substantial proportion of women will still be diagnosed with some type of gynecologic cancer during their reproductive age. Over 10% of newly diagnosed ovarian cancers and over one third of newly diagnosed cervical cancers involve women who are under the age of 45. This, coupled with the rising trend of women having their first child after the age of 35, has led to a concerning prevalence of complex fertility issues among women who have been diagnosed with cancer. Since the advent of robotic-assisted surgeries in gynecology, there has been a rise in the occurrence of these procedures. Fertility preserving gynecological surgeries require precise management in order to avoid fertility disorders. Therefore, we conducted a narrative review of robotic assisted fertility sparing surgery in gynecologic malignancies in order to highlight the role of this approach in preserving fertility.

Oncologic and Fertility Outcomes After Simple Trachelectomy in Women With Early Cervical Cancer

STUDY OBJECTIVE

This study aimed to present our case series of patients with early-stage cervical cancer undergoing simple trachelectomy (ST). Currently, radical trachelectomy is considered the most appropriate fertility-preserving procedure for the treatment of early-stage cervical cancer. However, there is increasing debate on the appropriate radicality of the surgery to preserve oncologic safety.

DESIGN

Descriptive retrospective analysis of patient records and evaluation of questionnaires.

SETTING

2 gynecologic oncologic centers, surgeries performed by one surgical team.

PATIENTS

36 women with early-stage cervical cancer undergoing ST.

INTERVENTIONS

Laparoscopic assisted simple vaginal trachelectomy.

MEASUREMENTS

Demographic, histologic, fertility, and follow-up data of all patients who underwent ST between April 2007 and July 2021 were prospectively recorded and retrospectively analyzed.

MAIN RESULTS

A total of 36 women (mean age: 28 years) underwent ST of whom 81% were nulliparous. Indications for ST were multifocal International Federation of Gynecology and Obstetrics stage IA1 (n = 30), stage IA1 L1 (n = 1), stage IA2 (n = 2), and stage IB1 (n = 3). Mandatory staging procedure was laparoscopic pelvic lymphadenectomy, including bilateral sentinel biopsy in 92% of the cases and systematic in 8%. Residual tumor was histologically confirmed in 8 specimens (22%); 18 women (50%) were seeking parenthood, and 13 succeeded (72%). There were 16 live births, all on term, with a median fetal weight of 3110 grams (2330-4420). One patient had a medical abortion owing to fetal congenital malformation. One pregnancy is ongoing. After a median follow-up of 91.5 months (9-174), all women are alive with no evidence of disease.

CONCLUSION

ST represents a de-escalation compared with radical trachelectomy and provides excellent oncologic results with an outstanding fertility rate and obstetric outcome for patients with early cervical cancer. However, clear indications for this tailored fertility-preserving surgery have to be defined in well-designed trials.

The focal point is the meticulous examination of radical trachelectomy, a surgical technique that addresses the oncological aspects of treatment and preserves fertility. The conclusion encapsulates vital findings, highlighting this approach's dual benefits and challenges. Furthermore, the implications for clinical practice underscore the paradigm shift that radical trachelectomy brings, urging healthcare professionals to consider its integration into personalized treatment plans. The review concludes with a compelling call to action for further research, emphasizing the importance of refining surgical techniques and fostering interdisciplinary collaboration to ensure the seamless implementation of radical trachelectomy. Overall, this review sets the stage for a transformative shift in the approach to early-stage cervical cancer, presenting radical trachelectomy as a promising frontier in the quest for effective and patient-centered interventions.

Fertility Preservation in Cervical Cancer-Treatment Strategies and Indications

Cervical cancer is frequently diagnosed in women during their reproductive years, and fertility preservation is an essential part of their cancer treatment. In highly selected patients with early stage, low-risk cervical cancer and a tumor size ≤ 2 cm, several treatment strategies can be offered for patients wishing to preserve fertility, including radical/simple trachelectomy or conization with pelvic lymph node assessment. Trachelectomy can be performed through a vaginal, abdominal, or minimally invasive approach and has been shown to have an equivalent oncologic outcome compared to radical hysterectomy. All surgical approaches for radical trachelectomy seem to have excellent survival with comparable oncologic outcomes. Nevertheless, patients undergoing vaginal trachelectomy have better obstetric outcomes compared to the other routes. In patients with larger tumors (2-4 cm), neoadjuvant chemotherapy followed by fertility-sparing surgery is an alternative option. Several chemotherapy regimens have been used for this indication, with a pathologic complete response rate of 17-73%. For locally advanced diseases that require radical hysterectomy or primary chemoradiation, fertility preservation can be performed using oocyte, embryo, or ovarian tissue cryopreservation, as well as ovarian transposition. For these patients, future pregnancy is possible through surrogacy. In addition to fertility preservation, ovarian transposition, where the ovaries are repositioned outside of the radiation field, is performed to maintain ovarian hormonal function and prevent premature ovarian failure. In summary, fertility-preservation treatment strategies for patients with early stage cervical cancer are continuously evolving, and less radical surgeries are becoming more acceptable. Additional and ongoing evidence is helping determine the impact of conservative procedures on oncologic and obstetric outcomes in these patients.

A meta-analysis of treatment for early-stage cervical cancer: open versus minimally invasive radical trachelectomy

BACKGROUND

In previous systematic reviews, meta-analysis was lacking, resulting in the statistical difference between the data of different surgeries being impossible to judge. This meta-analysis aims to contrast the fertility results and cancer outcomes between open and minimally invasive surgery.

METHOD

We systematically searched databases including PubMed, Embase, Cochrane, and Scopus to collect studies that included open and minimally invasive radical trachelectomy. A random-effect model calculated the weighted average difference of each primary outcome via Review Manager V.5.4.

RESULT

Eight studies (1369 patients) were incorporated into our study. For fertility results, the Open group excels MIS group in pregnancies-Third trimester delivery [OR = 2.68; 95% CI (1.29, 5.59); P = 0.008]. Nevertheless, there is no statistical difference in clinical pregnancy, miscarriage, and second-trimester rate. Concerning cancer outcomes, no difference was detected in the overall survival [OR = 1.56; 95% CI (0.70, 3.45); P = 0.27] and recurrence [OR = 0.63; 95% CI (0.35, 1.12); P = 0.12]. Concerning surgery-related outcomes, the comprehensive effects revealed that the estimated blood loss of the Open group was higher than that of the MIS group[MD = 139.40; 95% CI (79.05, 199.75); P < 0.0001]. However, there was no difference between the postoperative complication rate in the two groups [OR = 1.52; 95% CI (0.89, 2.60); P = 0.12].

CONCLUSION

This meta-analysis suggested that the fertility result of the Open group may be better than the MIS group, while the MIS group has better surgery-related outcomes. Owing to the poor cases of our study, a more robust conclusion requires more relevant articles in the future.

Minimally invasive versus abdominal radical trachelectomy for early-stage cervical cancer: a systematic review and meta-analysis

The safety of minimally invasive surgery (MIS) for cervical cancer has been questioned. This systematic review and meta-analysis aimed to compare the clinical outcomes of patients with cervical cancer who underwent MIS and abdominal trachelectomy. We searched for and subsequently analyzed studies published in PubMed, Embase, Cochrane Central Register of Controlled Trials, International Clinical Trials Registry Platform, and Clinical Trials.gov from their inception until April 10, 2023. Six studies with 1,079 participants were included, constituting 512 and 567 patients in the MIS and abdominal surgery groups, respectively. No significant difference was observed in the overall survival (hazard ratio [HR], 0.51; 95% confidence interval [CI], 0.16-1.65; I2=0.0%; P=0.881), recurrence rate (RR, 1.26; 95% CI, 0.68-2.33; I2=0.0%; P=0.815), and death rate (RR, 0.54; 95% CI, 0.23-1.31; I2=0.0%; P=0.680) between the MIS and abdominal surgery groups. No significant difference was found in urinary tract complication (RR, 0.78; 95% CI, 0.28-2.17; I2=0.0%; P=0.603), cerclage erosion (RR, 0.90; 95% CI, 0.34-2.43; I2=0.0%; P=0.650), or cervical stenosis (RR, 0.69; 95% CI, 0.22-2.18; I2=0.0%; P=0.885) between both groups. However, significant differences in blood loss and length of hospital stay were observed between both groups. Among 49 females who attempted to get pregnant, 31.3% (5/16) and 51.5% (17/33) in the MIS and abdominal surgery groups, respectively, succeeded in conceiving. We established that laparoscopic and abdominal radical trachelectomy had similar efficacies for treating patients with early cervical cancer, with no significant differences in survival, tumor recurrence, and mortality rates. Additionally, they showed no significant differences in pregnancy-related outcomes. However, owing to the limited number of studies, more high-quality cohort studies are required to confirm these findings.

Safety of assisted reproductive techniques in gynecological cancer patients

PURPOSE OF REVIEW

Gynecological cancer is a very important cause of comorbidity and mortality in women. The current delay in motherhood is increasing the incidence of women under 40 years of age that have not yet achieved their maternity goals when they are diagnosed and standard treatment negatively impacts the reproductive potential of cancer survivors. In this review, we update the information available about the safety of fertility-sparing treatments in young gynecological cancer patients, as well as the safety and efficacy of assisted reproductive techniques (ART) in such group. We also evaluate the long-term gynecological cancer risk in women requiring ART.

RECENT FINDINGS

Although eligibility criteria continue to be very strict, there are more and more reports of fertility-sparing approaches outside of what traditionally has been considered safe. Molecular assessment is starting to be used in the selection of appropriate candidates. Data increasingly shows the long term safety and the efficacy of ART and pregnancy in these patients.

SUMMARY

Appropriate selection is key to safely preconize fertility-sparing alternatives. Because subfertility may be a result of these procedures, ART could be indicated in this setting. Neither ART nor pregnancy appear to increase recurrences or affect survival rates.

Conservative treatment of cervical cancer: A single center experience over a two-decade period

Objective

To report the surgical, oncological, and obstetrical outcomes of the different surgical techniques used for the fertility-sparing treatment of patients with early-stage cervical cancer.

Methods

We retrospectively analyzed all fertility-sparing procedures performed between 2004 and 2020. The study included patients desiring to preserve fertility who had squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinoma histology, all grades, and FIGO 2009 stage IA2-IB1 tumors.

Results

48 patients met the inclusion criteria. Eight patients (16.7%) had stage IA2, and 40 (83.3%) had stage IB1 tumors. Conization with pelvic lymph node assessment was performed in 5 (10.4%) patients, an open radical trachelectomy in 21 (43.8%), and a laparoscopic radical trachelectomy in 22 (45.8%). No major intraoperative complications were registered. Two patients required surgery due to an early postoperative complication. Late postoperative complications were seen in 15 patients (31.2%), with cervical stenosis being the most frequent (60%). The rate of DFS at 2 and 5 years was 89% (95% CI, 76-95%), and the 5- year OS was 96% (95% CI, 83-98%). Univariate analysis demonstrated a relationship between tumor size and recurrence, but not for other prognostic tumor factors or surgical approach. One patient (4.8%) developed recurrent disease in the open radical trachelectomy group, and five (22.7%) in the laparoscopic radical trachelectomy group. The pregnancy rate was 41.4%, and the live birth rate 88.2%.

Conclusion

Fertility-sparing treatment for patients with early-stage cervical cancer is ever-evolving. This study adds information to the literature about the outcomes of these quite uncommon procedures, and allows a critical analysis of many of the topics which are under discussion.

Fertility-sparing options for cancer patients

Fertility preservation is becoming an integral part of cancer care among women of reproductive age. Despite advances in the treatment of pelvic malignancies, all the currently available treatment approaches, including radiotherapy, chemotherapy, and surgery, place women at high risk for future fertility impairment. With improved long-term survival rates associated with cancer, expanding the reproductive options available is of high priority. Several fertility preservation options are available today for women with gynecologic and non-gynecologic malignancies. Depending on the underlying oncological entity, these can include the following procedures whether alone or in combination: oocyte cryopreservation, embryo cryopreservation, ovarian tissue cryopreservation, ovarian transposition, and trachelectomy. The purpose of this review is to provide the most up-to-date information on the aforementioned fertility-preserving approaches and highlight the current challenges, drawbacks, and areas of research where more data are still very necessary to optimize outcomes in young female oncological patients desiring pregnancy in the future.

Fertility-Sparing Surgery versus Radical Hysterectomy in Early Cervical Cancer: A Propensity Score Matching Analysis and Noninferiority Study

Objective: Fertility-sparing surgery (FSS) is the treatment of choice for patients with early cervical cancer (ECC) and fertility desire, but survival rates compared to radical hysterectomy (RH) have been scarcely reported. The aim of this study was to analyse the oncological outcomes of FSS compared to a balanced group of standard RH. Methods: A retrospective multicentre study of ECC patients who underwent FSS or RH was carried out in 12 tertiary hospitals in Spain between January 2005 and January 2019. The experimental group included patients who underwent a simple and radical trachelectomy, and the control group included patients who underwent RH. Optimal 1:1 propensity score (PS) matching analysis was performed to balance the series. Results: The study included 222 patients with ECC; 111 (50%) were treated with FSS, and 111 (50%) were treated with RH. After PS matching, a total of 38 patients in the FSS group and 38 patients in the RH group were analysed. In both groups, the overall survival (HR 2.5; CI 0.89, 7.41) and recurrence rates (28.9% in the FSS group vs. 13.2% in RH group) were similar. The rate of disease-free survival at 5 years was 68.99% in the FSS group and 88.01% in the RH group (difference of −19.02 percentage points; 95% CI −32.08 to −5.96 for noninferiority). In the univariate analysis, only tumour size reached statistical significance. Conclusion: FSS offers excellent disease-free and overall survival in women with ECC with fertility desire and is not inferior compared to RH.

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.

Management of Early-Stage Cervical Cancer: A Literature Review

Simple Summary

Despite being a preventable disease, cervical cancer still causes morbidity and deaths worldwide. In the early stages (FIGO IA1 with lymph-vascular space invasion-IIA1), the disease is highly curable. The primary treatment for early-stage cervical cancer is radical hysterectomy with pelvic lymphadenectomy. This surgical treatment has changed during the past decades, and we aimed to review and discuss the advances in the literature. We performed a literature review through PubMed focusing on English articles about the topic of surgical management of early-stage cervical cancer. The emergent topics considered here are the FIGO 2018 staging system update, conservative management for selected patients, sentinel lymph node mapping, fertility preservation, surgical approach, and management of tumors up to 2 cm. These topics show an evolvement to a more tailored treatment to prevent morbidity and assure oncologic safety.

Abstract

Cervical cancer (CC) remains a public health issue worldwide despite preventive measures. Surgical treatment in the early-stage CC has evolved during the last decades. Our aim was to review the advances in the literature and summarize the ongoing studies on this topic. To this end, we conducted a literature review through PubMed focusing on English-language articles on the surgical management of early-stage CC. The emergent topics considered here are the FIGO 2018 staging system update, conservative management with less radical procedures for selected patients, lymph node staging, fertility preservation, preferred surgical approach, management of tumors up to 2 cm, and prognosis. In terms of updating FIGO, we highlight the inclusion of lymph node status on staging and the possibility of imaging. Regarding the preferred surgical approach, we emphasize the LACC trial impact worldwide in favor of open surgery; however, we discuss the controversial application of this for tumors < 2 cm. In summary, all topics show a tendency to provide patients with tailored treatment that avoids morbidity while maintaining oncologic safety, which is already possible in high-income countries. We believe that efforts should focus on making this a reality for low-income countries as well.

Fertility-Sparing and Less Radical Surgery for Cervical Cancer

PURPOSE OF REVIEW

Patients with early-stage cervical cancer who desire future fertility may be candidates for less radical surgery. We review the literature supporting this approach in early-stage disease.

RECENT FINDINGS

Retrospective data have shown that in carefully selected patients, the risk of parametrial involvement is less than 1%. This has led to interest in moving away from radical surgery towards more conservative approaches. Data from the newly published ConCerv trial, a prospective study evaluating the feasibility of conservative surgery in women with early-stage, low-risk cervical carcinoma, suggest that conservative surgery is feasible and safe in this patient population. Furthermore, neoadjuvant chemotherapy is being assessed as an option to extend fertility-sparing treatment to a larger group of women. Less radical surgery may be appropriate for carefully selected women with early-stage, low-risk cervical cancer, including those desiring future fertility.
