vNOTES Radical Hysterectomy: A New Approach to Cervical Cancer

OBJECTIVE

To demonstrate how a radical hysterectomy with sentinel node resection for cervical cancer can be performed via vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES).

DESIGN

Demonstration of the technique in 10 steps. making use of narrated original video footage SETTING: The surgical treatment of cervical cancer is traditionally performed via one of the following techniques: Wertheim radical hysterectomy via laparotomy, Schauta radical hysterectomy vaginally, laparoscopic radical hysterectomy or robotic radical hysterectomy. The results of the LACC trial showed that minimally invasive radical hysterectomy was associated with lower rates of disease-free survival and overall survival than open radical hysterectomy among women with early-stage cervical Cancer [1]. For endometrial cancer, a vNOTES retroperitoneal approach to sentinel node resection was first published in 2019 [2]. Based on the experience with this approach and with Schauta-Stoeckel radical hysterectomy for cervical cancer [3], a new approach was developed to perform a radical hysterectomy via vNOTES whereby most of the procedure is performed retroperitoneally [4]. This video article demonstrates in 10 steps how a radical hysterectomy via vNOTES is performed.

INTERVENTIONS

Radical hysterectomy via vNOTES demonstrated making use of original video footage of a 57-year-old woman operated on for cervical adenocarcinoma 7 weeks after a LEEP cone. The steps of the procedure are: 1. Vaginal cuff creation, 2. Development of lateral retroperitoneal space and sentinel node resection, 3. Uterine artery and vein transection, 4. Hypogastric nerve dissection, 5. Development of central retroperitoneal space and rectum dissection, 6. Posterior colpotomy, 7. Parametrium dissection, 8. Bladder pillar dissection, 9. Anterior colpotomy, 10. Salpingo-oophorectomy or salpingectomy. 3 Patients were so far treated by this new technique that allowed for good hemostatic control.

CONCLUSION

vNOTES enables a potentially less invasive approach to radical hysterectomy performed largely retroperitoneally and completely transvaginally, leaving no visible scars. The endoscopic approach offers excellent visualization of the retroperitoneal and parametrial anatomy. This is a new approach that requires further validation and should only be performed in a research setting, taking into account the current reservations about endoscopic surgery for cervical cancer resulting from the LACC trial. VIDEO ABSTRACT.

Simple hysterectomy versus radical hysterectomy in early-stage cervical cancer: A systematic review and meta-analysis

BACKGROUND

This systematic review (SR) and meta-analysis aims to compare the surgery-related results and oncological outcomes between SH and RH in patients with early-stage cervical cancer.

METHOD

We systematically searched databases including PubMed, Embase and Cochrane to collect studies that compared oncological and surgery-related outcomes between SH and RH groups in patients with stage IA2 and IB1 cervical cancer. A random-effect model calculated the weighted average difference of each primary outcome via Review Manager V.5.4.

RESULT

Seven studies comprising 6977 patients were included into our study. For oncological outcomes, we found no statistical difference in recurrence rate [OR = 0.88; 95% CI (0.50, 1.57); P = 0.68] and Overall Survival (OS) [OR = 1.23; 95% CI (0.69, 2.19), P = 0.48]. No difference was detected in the prevalence of positive LVSI and lymph nodes metastasis between the two groups. Concerning surgery-related outcomes, the comprehensive effects revealed that the bladder injury [OR = 0.28; 95% CI (0.08, 0.94), P = 0.04] and bladder disfunction [OR = 0.10; 95% CI (0.02, 0.53), P = 0.007] of the RH group were higher compared to the SH group.

CONCLUSION

This meta-analysis suggested there are no significant differences in terms of both recurrence rate and overall survival among patients with stage IA2-IB1 cervical cancer undergoing SH or RH, while the SH group has better surgery-related outcomes. These data confirm the need to narrow the indication for RH in early-stage cervical cancer.

Outcomes of neoadjuvant chemotherapy and radical hysterectomy for locally advanced cervical cancer at Kigali University Teaching Hospital, Rwanda: a retrospective descriptive study

BACKGROUND

Half of countries in Africa lack access to radiation (RT), which is essential for standard treatment of locally advanced cervical cancers. We evaluated outcomes for patients treated with neoadjuvant chemotherapy (NACT) followed by radical hysterectomy in settings where no RT is available.

METHODS

We performed a retrospective descriptive study of all patients with FIGO stage IB2-IIA2 and some exceptional stage IIB cases who received NACT and surgery at Kigali University Teaching Hospital in Rwanda. Patients were treated with NACT consisting of carboplatin and paclitaxel once every 3 weeks for 3-4 cycles before radical hysterectomy. We calculated recurrence rates and overall survival (OS) rate was determined by Kaplan-Meier estimates.

RESULTS

Between May 2016 and October 2018, 57 patients underwent NACT and 43 (75.4%) were candidates for radical hysterectomy after clinical response assessment. Among the 43 patients who received NACT and surgery, the median age was 56 years, 14% were HIV positive, and FIGO stage distribution was: IB2 (32.6%), IIA1 (7.0%), IIA2 (51.2%) and IIB (9.3%). Thirty-nine (96%) patients received 3 cycles and 4 (4%) received 4 cycles of NACT. Thirty-eight (88.4%) patients underwent radical hysterectomy as planned and 5 (11.6%) had surgery aborted due to grossly metastatic disease. Two patients were lost to follow up after surgery and excluded from survival analysis. For the remaining 41 patients with median follow-up time of 34.4 months, 32 (78%) were alive with no evidence of recurrence, and 8 (20%) were alive with recurrence. One patient died of an unrelated cancer. The 3-year OS rate for the 41 patients who underwent NACT and surgery was 80.8% with a recurrence rate of 20%.

CONCLUSIONS

Neoadjuvant chemotherapy with radical hysterectomy is a feasible treatment option for locally advanced cervical cancer in settings with limited access to RT. With an increase in gynecologic oncologists skilled at radical surgery, this approach may be a more widely available alternative treatment option in countries without radiation facilities.

Intraoperative implantation of 125I seeds improves prognosis in refractory stage IIIB cervical cancer: a case report and literature review

BACKGROUND

Concurrent chemoradiation is the standard treatment for advanced cervical cancer. However some patients still have a poor prognosis, and currently, there is no effective treatment for recurrence. In recent years, 125I seed implantation therapy has emerged as a treatment for advanced malignant tumors including surgically unresectable tumors, residual tumors after surgical resection, and metastatic tumors. However, the use of 125I seeds implantation in primary advanced cervical cancer has not been reported. In this study, we present a case of stage IIIB cervical cancer in a patient who had poor response to radiotherapy and chemotherapy. Subsequently, a radical hysterectomy was performed, and 125I radioactive seeds were successfully implanted during the surgery. This effectively controlled the lesions that were resistant to radiotherapy and had the potential to improve the prognosis.

CASE PRESENTATION

A 56-year-old woman was diagnosed with stage IIIB (FIGO 2009) IIIC1r (FIGO 2018) squamous carcinoma of the cervix. After receiving 4 cycles of platinum-based chemotherapy and 30 rounds of radiotherapy, she underwent a radical hysterectomy. The localized cervical lesions were reduced, but there was no reduction in the size of the enlarged pelvic lymph nodes. Therefore, 125I seed implantation was performed under direct surgical vision for the right paracervical lesion and the enlarged pelvic lymph nodes on the right side. During the 18-month follow-up period, the enlarged lymph nodes subsided without any signs of recurrence or metastasis.

CONCLUSION

Intraoperative implantation of 125I seeds in lesions that are difficult to control with radiotherapy or in sites at high risk of recurrence is a feasible and effective treatment option for patients with advanced squamous cervical cancer, and it may contribute to improved survival.

Diagnosis and management of gastric-type endocervical adenocarcinoma: A case report and review of the literature

Gastric-type endocervical adenocarcinoma (GEA), a rare subtype of cervical cancer, has garnered increasing attention recently for its distinctive histopathological features, unique classification, genetic characteristics, and variable clinical outcomes compared to squamous cell and adenocarcinoma subtypes. Historically, GEA has evolved from a poorly understood entity to a distinct subtype of cervical adenocarcinoma, only recently recognized in the 2020 World Health Organization (WHO) classification. Accordingly, characteristic morphological features define GEA, shedding light on the diagnostic challenges and potential misclassification that can occur in clinical practice. Genetic alterations, including KRAS, ARID1A, and PIK3CA mutations, play a pivotal role in the development and progression of GEA. This article reviews a case of GEA and aims to provide a contemporary overview of the genetic mutations and molecular pathways implicated in GEA pathogenesis, highlighting potential therapeutic targets and the prospects of precision medicine in its management. Patients with GEA have variable clinical outcomes, with some exhibiting aggressive behavior while others follow a more indolent course. This review examines the factors contributing to this heterogeneity, including stage at diagnosis, histological grade, and genetic alterations, and their implications for patient prognoses. Treatment strategies for GEA remain a topic of debate and research. Here, we summarize the current therapeutic options, including surgery, radiation therapy, and chemotherapy, while also exploring emerging approaches, such as targeted therapies and immunotherapy. This article provides a comprehensive overview of GEA, synthesizing current knowledge from historical perspectives to contemporary insights, focusing on its classification, genetics, outcomes, and therapeutic strategies.

Treatment for locally resectable stage IIIC1r cervical cancer: surgery or chemoradiotherapy?

OBJECTIVE

The aim of this study was to compare the therapeutic value and treatment-related complications of radical hysterectomy with those of concurrent chemoradiotherapy (CCRT) for locally resectable (T1a2-T2a1) stage IIIC1r cervical cancer.

METHODS

A total of 213 patients with locally resectable stage IIIC1r cervical cancer who had been treated at Jiangxi Maternal and Child Health Care Hospital between January 2013 and December 2021 were included in the study and classified into two groups: surgery (148 patients) and CCRT (65 patients). The disease-free survival (DFS) rate, overall survival (OS) rate, side effects, and economic costs associated with the two groups were compared.

RESULTS

43.9% (65/148) patients in the surgical group had no pelvic lymph node metastasis, and 21of them did not require supplementary treatment after surgery due to a low risk of postoperative pathology. The median follow-up time was 46 months (range: 7-108 months). The five-year DFS and OS rates of the surgery group were slightly higher than those of the CCRT group (80.7% vs. 75.1% and 81.6% vs. 80.6%, respectively; p > 0.05). The incidences of grade III-IV gastrointestinal reactions in the surgery and CCRT groups were 5.5% and 9.2%, respectively (p = 0.332). Grade III-IV myelosuppression was identified in 27.6% of the surgery group and 26.2% of the CCRT group (p = 0.836). The per capita treatment cost was higher for the surgery group than for the CCRT group (RMB 123, 918.6 0 vs. RMB 101, 880.90, p = 0.001).

CONCLUSION

The therapeutic effects and treatment-related complications of hysterectomy and CCRT are equivalent in patients with locally resectable stage IIIC1r cervical cancer, but surgery can provide accurate lymph node information and benefit patients with unnecessary radiation.

Cervical cancer management in a low resource setting: A 10-year review in a tertiary care hospital in Kenya

Background

Cervical cancer is one of the leading causes of cancer mortality among women in Kenya due to late presentations, poor access to health care, and limited resources. Across many low- and middle-income countries infrastructure and human resources for cervical cancer management are currently insufficient to meet the high population needs therefore patients are not able to get appropriate treatment.

Objective

This study aimed to describe the clinicopathological characteristics and the treatment profiles of cervical cancer cases seen at Moi Teaching and Referral Hospital (MTRH).

Methods

This was a retrospective cross-sectional study conducted at MTRH involving the review of the electronic database and medical charts of 1541 patients with a histologically confirmed diagnosis of cervical cancer between January 2012 and December 2021.

Results

Of the 1541 cases analyzed, 91% were squamous cell carcinomas, 8% were adenocarcinomas, and 1% were other histological types. Thirty-eight percent of the patients were HIV infected and less than 30% of the women had health insurance. A majority (75%) of the patients presented with advanced-stage disease (stage IIB-IV). Only 13.9% received chemoradiotherapy with curative intent; of which 33.8% received suboptimal treatment. Of the 13% who received surgical treatment, 45.3% required adjuvant therapy, of which only 27.5% received treatment. Over 40% of the women were lost to follow-up.

Conclusion

Most of the patients with cervical cancer in Kenya present at advanced stages with only a third receiving the necessary treatment while the majority receive only palliative treatment or supportive care.

The role of obesity in treatment planning for early-stage cervical cancer

OBJECTIVES

Optimal management of obese patients with early-stage cervical cancer is debated despite evidence of non-inferior survival in obese patients undergoing radical hysterectomy with pelvic lymphadenectomy (RH) compared to primary radiation with or without radiosensitizing chemotherapy (RT). Objectives included describing patient factors affecting disposition to RH versus RT; comparing RH outcomes for obese (BMI >30 mg/m2) and non-obese patients; and comparing differences in recurrence free survival (RFS) and overall survival (OS).

METHODS

This was a single institution cohort study of all cervical cancer patients who underwent RH or were candidates for RH based on clinical stage. Demographic, clinicopathologic and treatment outcomes were collected and analyzed.

RESULTS

RT patients (n = 39, 15%) had a higher BMI (p = 0.004), older age (p < 0.001), more life-limiting comorbidities (LLC) (p < 0.001), larger tumor size (p = 0.001), and higher clinical stage (p = 0.013) compared to RH patients (n = 221, 85%). On multivariable survival analysis there was no difference in OS based on treatment modality; significant predictors of worse OS were larger tumor size, higher number of LLC and recurrence. Among the RH group, obese patients had a longer operative time (p = 0.01) and more LLC (p = 0.02); there were no differences in demographic or clinicopathologic characteristics, operative outcomes, RFS or OS compared to non-obese patients.

CONCLUSION

In this cohort of RH-eligible cervical cancer patients, BMI was independently associated with disposition to RT. Studies demonstrate that RH is feasible and safe in obese patients with no difference in RFS or OS when compared to non-obese patients. Thus, the decision for disposition to RT should not be based on obesity alone.

Robotic radical hysterectomy after conization for patients with small volume early-stage cervical cancer

Laparoscopy and robotics are recommended for managing gynecological cancer, as they are associated with lower morbidity and comparable outcomes to open surgery. However, in the case of early cervical cancer, new evidence suggests worse oncological outcomes with these approaches compared to open surgery, though the limited number of robotic cases makes it challenging to draw definitive conclusions for this particular approach. The prior conization has been proposed as a strategy to reduce the risk of tumor spillage and contamination during minimally invasive (MIS) radical hysterectomy (RH). Retrospective studies have indicated that undergoing conization before RH is linked to a reduced risk of recurrences, especially in cervical tumors measuring less than 2 cm. Nevertheless, these studies lack the statistical power needed to definitively establish conization as a recommended step before RH. Furthermore, these studies do not have enough cases utilizing the robotic approach and specific conclusions cannot be drawn from this technique. The question of whether a subset of cases would benefit from preoperative conization and whether conization should be performed to recommend MIS over open surgery remains unanswered. Prospective clinical trials involving women diagnosed with early-stage cervical cancer <2 cm, randomized between undergoing conization before robotic RH or without prior conization are mandatory to assess the role of conization before robotic RH in cervical cancer.

Prediction of recurrence-related factors for patients with early-stage cervical cancer following radical hysterectomy and adjuvant radiotherapy

OBJECTIVE

To analyze recurrent factors in patients with clinical early-stage cervical cancer (ESCC) following hysterectomy and adjuvant radiotherapy.

METHODS

We collected data from patients with ESCC, staged according to the 2009 Federation International of Gynecology and Obstetrics (FIGO) staging criteria, who underwent hysterectomy followed by adjuvant radiotherapy between 2012 and 2019. These patients were subsequently restaged using the 2018 FIGO criteria. Univariable and multivariable analyses, along with nomogram analyses, were conducted to explore factors associated with recurrence-free survival (RFS).

RESULTS

A total of 310 patients met the inclusion criteria, with a median follow-up time of 46 months. Among them, 126 patients with ESCC were restaged to stage III C1 or III C2 after surgery due to lymph node metastasis (LNM) based on the 2018 FIGO staging criteria. Of these, 60 (19.3%) experienced relapse. The 1-, 3-, and 5-year RFS rates were 93.9%, 82.7%, and 79.3%, respectively. Multivariate analysis revealed that the number of positive lymph nodes (LNs), tumor diameter (TD) > 4 cm, and parametrial invasion (PI) were associated with recurrence. The nomogram indicated their predictive value for 3-year and 5-year RFS. Notably, the 5-year recurrence rate (RR) increased by 30.2% in patients with LNM, particularly those with ≥ 3 positive LNs (45.5%). Patients with stage III C2 exhibited a significantly higher RR than those with IIIC1 (56.5% vs. 24.3%, p < 0.001). The 5-year RFS for patients with TD > 4 cm was 65.8%, significantly lower than for those with TD ≤ 4 cm (88.2%). Subgroup analysis revealed higher 5-year RRs in patients with stage III C2 than that in patients with III-C1 (56.5% vs. 24.3%, p < 0.001), demonstrating a significant difference in the RFS survival curve.

CONCLUSION

RR in patients with clinical ESCC after hysterectomy followed by adjuvant radiotherapy is correlated with the number of positive LNs, TD > 4 cm, and PI. Emphasis should be placed on the common high-risk factor of LNM association with recurrence after radical hysterectomy in ESCC.

Radical hysterectomy case volume and cervical cancer treatment in the era of COVID-19: A multi-site analysis of National Cancer Institute-designated Comprehensive Cancer Centers

OBJECTIVE

To compare radical hysterectomy case volume, cancer stage, and biopsy-to-treatment time of invasive cervical cancer diagnosed before and after onset of the COVID-19 pandemic.

METHODS

In a multi-institution retrospective cohort study conducted at 6 large, geographically diverse National Cancer Institute-designated cancer centers, patients treated for newly diagnosed invasive cervical cancer were classified into 2 temporal cohorts based on date of first gynecologic oncology encounter: (1) Pre-Pandemic: 3/1/2018-2/28/2020; (2) Pandemic & Recovery: 4/1/2020-12/31/2021. The primary outcome was total monthly radical hysterectomy case volume. Secondary outcomes were stage at diagnosis and diagnosis-to-treatment time. Statistical analyses used chi-squared and two sample t-tests.

RESULTS

Between 3/1/2018-12/31/2021, 561 patients were diagnosed with cervical cancer. The Pre-Pandemic and Pandemic & Recovery cohorts had similar age, race, ethnicity, smoking status, and Body Mass Index (BMI). During Pandemic & Recovery, the mean monthly radical hysterectomy case volume decreased from 7[SD 2.8] to 5[SD 2.0] (p = 0.001), the proportion of patients diagnosed with Stage I disease dropped from 278/561 (49.5%) to 155/381 (40.7%), and diagnosis of stage II-IV disease increased from 281/561 (50.1%) to 224/381 (58.8%). Primary surgical management was less frequent (38.3% Pandemic & Recovery versus 46.7% Pre-Pandemic, p = 0.013) and fewer surgically-treated patients received surgery within 6 weeks of diagnosis (27.4% versus 38.9%; p = 0.025).

CONCLUSIONS

Lower radical hysterectomy case volume, a shift to higher cervical cancer stage, and delay in surgical therapy were observed across the United States following the COVID-19 outbreak. Decreased surgical volume may result from lower detection of early-stage disease or other factors.

High uterosacral ligament suspension in radical hysterectomy: a step-by-step procedure to prevent pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

Given the younger age of cervical cancer patients and improved postoperative survival, postoperative quality of life should be a reason for concern, particularly given the prevalence of pelvic floor dysfunction. High uterosacral ligament suspension (HUS) has been deemed the more consistently successful surgery for the treatment of mid-pelvic abnormalities. HUS intraoperatively prevents pelvic floor dysfunction effectively.

METHODS

We demonstrate the steps of surgery using surgical video and photographs. The uterosacral ligament is fan shaped and connected to the fascial and extraosseous membranes on the surface of the anterior sacral foramen of the 2nd, 3rd, and 4th sacral vertebrae. Given that the uterosacral ligament was fan-shaped, the fan-shaped suture with three stitches was more compatible with the original anatomy.

RESULTS

Thirty patients with HUS who underwent thorough hysterectomy had no complications, operation time 230.82 ± 43.61 min, and blood loss 62.32 ± 37.25 ml. The urinary catheter was successfully removed 1 week after the operation, and no pelvic organ prolapse, including vaginal anterior and posterior wall prolapse, or rectocele, occurred after 3 years of follow-up.

CONCLUSION

The uterosacral ligament fulfills the role of supporting, pulling, and suspending the uterus. We should exploit the advantage of fully exposing the uterosacral ligament in radical hysterectomy. Performing HUS to prevent pelvic organ prolapse following radical hysterectomy is a procedure worthy of investigation and promotion.

Development of a risk nomogram predicting urinary tract infection in patients with indwelling urinary catheter after radical surgery for cervical cancer

BACKGROUND

Cervical cancer (CC) patients receiving indwelling catheterization after radical hysterectomy (RH) are vulnerable to urinary tract infection (UTI). However, no model or method is available to predict the risk of UTIs. Therefore, our aim was to develop and verify a risk model to predict UTI for patients receiving indwelling catheterization after radical cervical cancer surgery (ICa-RCCS).

METHODS

We first collected clinical information of 380 patients receiving ICa-RCCS from January 2020 to December 2021 as a training cohort to develop the risk nomogram. UTI was then evaluated using 19 UTI predictor factors. The least absolute shrinkage and selection operator (LASSO) method was utilized for the extraction characteristics. Multivariable logistic regression analysis was then conducted to create the risk model for UTI prediction. The consistency coefficient and calibration curve were utilized to assess the model's fit accuracy. We performed bootstrapping with 1000 random samples for internal validation of the model, and decision curve analysis (DCA) for clinical application.

RESULTS

Predictors in the risk nomogram included indwelling catheterization duration, whether it is secondary indwelling catheterization, history of UTIs, age, and history of chemotherapy before surgery. The risk nomogram presented good discrimination and calibration (C-index: 0.810, 95% CI: 0.759-0.861). During interval validation, the model reached a high C-index up to 0.7930. DCA revealed the clinical utility of predictive model for UTI. Clinical benefit was initiated at the decision threshold≥3%.

CONCLUSION

We developed a novel UTI nomogram incorporating the age, history of chemotherapy before surgery, indwelling catheterization duration, whether it is secondary indwelling catheterization, and history of UTI to predict UTI risk for patients receiving ICa-RCCS.

The efficacy of ureteroscopic triage in increasing the cure rate of the first-line treatment for a ureterovaginal fistula resulting from radical hysterectomy

Study objective

To explore the effect of pretreatment with ureteroscopic triage for iatrogenic ureterovaginal fistula (UVF) resulting from radical hysterectomy.

Design

A retrospective cohort study.

Setting

Department of gynecology at a tertiary medical center.

Patients

Women diagnosed with UVF secondary to radical hysterectomy at our center between April 2008 to June 2018.

Interventions

The patients were divided into two groups according to whether pretreatment with ureteroscopic triage was performed. Those in the non-triage group underwent retrograde placement of a double-J stent immediately following diagnosis as the first-line therapy. Patients in the triage group were first evaluated under ureteroscopy, their ureteral injuries were then classified into different grades and then underwent different treatments as the first-line therapy, including stent placement or reconstruction surgeries. The cure rate of the first-line therapy and the timeliness of the implementation of adjuvant radiotherapy were subsequently analyzed.

Measurements and main results

Ninety-eight UVF patients were included. The demographics, ECOG status, stage of cervical cancer (FIGO 2009), types and onset time of symptoms were not different between the two groups. There were 54 patients in the nontriage group, with an overall first-line cure rate of 70.4% and a timely implementation rate of adjuvant radiotherapy of 38.5%. There were 44 patients in the evaluation group, with an overall first-line cure rate of 93.2% and a timely implementation rate of adjuvant radiotherapy of 90.0%. The differences were statistically significant (p < 0.001).

Conclusion

Ureteroscopic triage of ureteral injuries can guide the selection of the optimal first-line therapy for patients with UVF secondary to radical hysterectomy, increase the cure rate and ensure the timely implementation of adjuvant radiotherapy.

Recently urodynamic and quality of life assessment in the non-menopausal women with cervical cancer after radical hysterectomy

PURPOSE

The aim of this study was to evaluate the pre- and postoperative changes in the recently urodynamic and quality of life (QoL) in nonmenopausal women diagnosed with cervical cancer and treated with radical hysterectomy (RH).

PATIENTS AND METHODS

Twenty-eight nonmenopausal women (28-49 years) with cervical carcinoma (FIGO stage Ia2-IIa) underwent a radical hysterectomy. Urodynamic studies were performed 1 week before (U0) and 3-6 months (U1) after surgery. A self-administered condition-specific QoL questionnaire (PFDI-20, PFIQ-7) was applied at U0 and U1.

RESULTS

Data from the urodynamics analysis performed at U1 showed that the average first sensation volume (119.39 ± 12.28 ml vs 150.43 ± 31.45 ml, P < 0.001), the residual urine volume (6.39 ± 10.44 ml vs. 42.32 ± 33.72 ml, P < 0.001), and the time of urination (46.10 ± 16.65 s vs. 74.31 ± 23.94 s, P < 0.001) were increased, while the bladder volume at a strong desire to void (448.89 ± 86.62 ml vs. 322.82 ± 50.89 ml, P < 0.001), the bladder compliance (82.63 ± 58.06 ml/cmH₂O vs. 37.45 ± 28.66 ml/cmH₂O, P < 0.001), the average flow rate (Qave) (23.86 ± 4.25 ml/s vs. 12.57 ± 2.37 ml/s, P < 0.001), the maximum natural flow rate (Qmax) (25.42 ± 6.46 ml/s vs. 14.43 ± 5.32 ml/s, P < 0.001), and the pressure at a peak flow rate (PdetQmax) (36.53 ± 11.20 cmH₂O vs. 31.43 ± 10.56 cmH₂O, P < 0.05) were decreased. At the same time, functional pelvic problems derived from prolapse (PFDI-20 scores) and their impact on the patients' Qol (PFIQ-7 score) were significantly improved at 3-6 months postoperation.

CONCLUSION

Radical hysterectomy results in urodynamic changes, and 3-6 months postoperation may be an important period for changes in bladder dysfunction after RH. Urodynamic and QoL analyses may provide methods for assessing symptoms.

Effect of modified radical laparoscopic hysterectomy versus open radical hysterectomy on short-term clinical outcomes in early-stage cervical cancer: a single-center, prospective, randomized controlled trial

BACKGROUND

The long-term prognosis of minimally invasive surgery and open surgery for early cervical cancer is controversial. This study mainly discusses the feasibility and effectiveness of the endocutter in radical laparoscopic hysterectomy for early cervical cancer.

METHODS

A single-center, prospective, randomized controlled trial of modified radical laparoscopic hysterectomy on patients with FIGO stage IA1 (lymphovascular invasion), IA2, and IB1 cervical cancer, between January 2020 and July 2021. Patients were randomly assigned into laparoscopic radical hysterectomy (LRH) and open radical hysterectomy (ORH) groups. The ORH group used right-angle sealing forceps for vaginal stump closure, whereas the LRH group used endoscopic staplers. The primary outcomes included the evaluation of the patient's perioperative indicators, as well as short- and long-term complications. Recurrence and overall survival were considered secondary outcomes.

RESULTS

As of July 2021, 17 patients were enrolled in the laparoscopic surgery group and 17 in the open surgery group. The hospitalization time of the laparoscopic group was significantly shorter than those of the open group (15 min vs. 9 min, P < 0.001). The vaginal stump closure time in the laparoscopic group was longer than that in the open surgery group, and the difference was statistically significant (P < 0.001). Post-operative catheter removal (P = 0.72), drainage tube removal time (P = 0.27), number of lymph node dissections (P = 0.72), and incidence of intraoperative and post-operative complications between the two groups (P > 0.05). The median blood loss in the laparoscopic group was 278 ml, and it was 350 ml in the laparotomy group. The intraoperative blood transfusion rate was lower in the laparoscopic group; however, these differences did not reach statistical significance (P = 0.175). Vaginal margin pathology and peritoneal lavage cytology were negative, and all the patient's vaginal stumps healed without infection. The median follow-up time of the laparoscopic group was 20.5 months, and it was 22 months for the open surgery group. There was no recurrence in all patients during the follow-up period.

CONCLUSIONS

Modified LRH with endocutter closure of the vaginal stump is an effective approach and not inferior to ORH in treating patients with early-stage cervical cancer.

Survival outcomes of laparoscopic versus open radical hysterectomy in early cervical cancer with incidentally identified high-risk factors

OBJECTIVE

Previously, we suggested that patients with cervical cancer (CC) with tumors ≤2 cm on preoperative magnetic resonance imaging (MRI) are safe candidates for laparoscopic radical hysterectomy (LRH). Here, we aim to investigate whether LRH deteriorates the prognosis of patients with incidentally identified high-risk factors; lymph node metastasis (LNM) or parametrial invasion (PMI).

METHODS

We identified patients with 2009 FIGO stage IB1 CC who underwent Type C LRH or open radical hysterectomy (ORH) at three tertiary hospitals between 2000 and 2019. Those with a tumor ≤2 cm on preoperative MRI who were not suspicious of LNM or PMI preoperatively were included, while those who were indicated to receive adjuvant treatment but did not actually receive it were excluded. Survival outcomes were compared between the LRH and ORH groups in the overall population, then narrowed down to those with LNM, and then to those with PMI.

RESULTS

In total, 498 patients were included: 299 in the LRH group and 199 in the ORH group. The LRH and ORH groups showed similar 3-year progression-free survival (PFS) (94.0% vs. 93.6%; P = 0.615) and 5-year overall survival (OS) rates (97.2% vs. 96.8%; P = 0.439). On pathologic examination, 49 (9.8%) and 16 (3.2%) patients had LNM and PMI, respectively, and 10 (2.0%) had both. In the LNM subgroup, 5-year PFS rate was not significantly different between the LRH and ORH groups (73.2% vs. 91.7%; P = 0.169). In the PMI subgroup, no difference in PFS was observed between the two groups (P = 0.893).

CONCLUSIONS

LRH might not deteriorate recurrence and mortality rates in CC patients with tumors ≤2 cm when adjuvant treatment is appropriately administered, even if pathologic LNM and PMI are incidentally identified.

Ten-year outcomes following laparoscopic and open abdominal radical hysterectomy for "low-risk" early-stage cervical cancer: A propensity-score based analysis

OBJECTIVE

Accumulating evidence suggested the detrimental effects of adopting minimally invasive surgery in the management of early-stage cervical cancer. However, long-term evidence on the role of minimally invasive radical hysterectomy in "low-risk" patients exists.

METHODS

This is multi-institutional retrospective study comparing minimally invasive and open radical hysterectomy in low-risk early-stage cervical cancer patients. A propensity-score matching algorithm (1:2) was used to allocate patients into the study groups. Kaplan-Meir model was used to estimate 10-year progression-free and overall survival.

RESULTS

Charts of 224 "low-risk" patients were retrieved. Overall, 50 patients undergoing radical hysterectomy were matched with 100 patients undergoing open radical hysterectomy. Minimally invasive radical hysterectomy was associated with a longer median operative time (224 (range, 100-310) vs. 184 (range, 150-240) minutes; p < 0.001), lower estimated blood loss (10 (10-100) vs. 200 (100-1000) ml, p < 0.001), and shorter length of hospital stay (3.8 (3-6) vs. 5.1 (4-12); p < 0.001). Surgical approach did not influence the risk of having intra-operative (4% vs. 1%; p = 0.257) and 90-day severe (grade 3+) postoperative complication rates (4% vs. 8%; p = 0.497). Ten-year disease-free survival was similar between groups (94% vs. 95%; p = 0.812; HR:1.195; 95%CI:0.275, 5.18). Ten-year overall survival was similar between groups (98% vs. 96%; p = 0.995; HR:0.994; 95%CI:0.182, 5.424).

CONCLUSIONS

Our study appears to support emerging evidence suggesting that, for low-risk patients, laparoscopic radical hysterectomy does not result in worse 10-year outcomes compared to the open approach. However, further research is needed and open abdominal radical hysterectomy remains the standard treatment for cervical cancer patients.

Conization before radical hysterectomy in patients with early-stage cervical cancer: A Korean multicenter study (COBRA-R)

OBJECTIVE

To investigate the impact of conization on survival outcomes and to identify a specific population that might benefit from conization before radical hysterectomy (RH) in patients with early-stage cervical cancer.

METHODS

From six institutions in Korea, we identified node-negative, margin-negative, parametria-negative, 2009 FIGO stage IB1 cervical cancer patients who underwent primary type C RH between 2006 and 2021. The patients were divided into multiple groups based on tumor size, surgical approach, and histology. We performed a series of independent 1:1 propensity score matching and compared the survival outcomes between the conization and non-conization groups.

RESULTS

In total, 1254 patients were included: conization (n = 355) and non-conization (n = 899). Among the matched patients with a tumor size of >2 cm, the conization group showed a significantly better 3-year disease-free survival (DFS) rate compared with the non-conization group when RH was conducted via minimally invasive surgery (MIS), in those with squamous cell carcinoma (96.3% vs. 87.4%, P = 0.007) and non-squamous cell carcinoma (97.0% vs. 74.8%, P = 0.021). However, no difference in DFS was observed between the two groups among the matched patients with a tumor size of ≤2 cm, regardless of surgical approach or histological type. In patients who underwent MIS RH, DFS significantly worsened as the residual tumor size increased (P < 0.001).

CONCLUSION

Cervical conization was associated with a lower recurrence rate in patients with early-stage cervical cancer with a tumor size of >2 cm who underwent primary MIS RH. Cervical conization may be performed prior to MIS RH to minimize the uterine residual tumor.

Laparoscopic modified radical hysterectomy for women with stage IV AFS endometriosis and obliterated Douglas space: a technical note (with video)

Excision of deep infiltrating endometriosis has to be complete to prevent symptomatic recurrences but with more complications. The patients with obliterated Douglas space who wish a definitive treatment for their pain require a more complex hysterectomy to remove all the lesions. Laparoscopic modified radical hysterectomy may allow to perform safely this surgery following 9 steps. The dissection is standardized according to anatomical landmarks. The key steps are: extrafascial dissection of uterine pedicle by opening the pararectal spaces and paravesical space, nerve sparing, ureterolysis if needed, the retrograde dissection of rectovaginal space and the rectal step if needed. The rectal step depends on depth of rectal infiltration and on the number of nodules (rectal shaving, disc excision or rectal resection). This standardized procedure could help surgeons to achieve a complex radical surgery for patients with endometriosis and obliterated Douglas space.

Isolated para-aortic nodal recurrence after treatment of early stage cervical carcinoma

OBJECTIVE

Surgical evaluation of lymph node metastasis is paramount in the treatment of cervical cancer. We sought to explore the outcomes of patients with and without para-aortic lymphadenectomy undergoing curative-intent radical hysterectomy for stage IA-IIA cervical cancer.

METHODS

Institutional data were retrospectively reviewed to identify women undergoing curative-intent radical hysterectomy with concurrent lymphadenectomy for stage IA-IIA cervical carcinoma from 2004 to 2021. Any carcinoma histology was allowed. Clinical risk stratification was performed according to GOG 92 and GOG 109 protocols. Disease outcomes, patterns of recurrence, and survival were analyzed with Chi square, t-test, Kaplan-Meier, and Cox proportional hazards multivariable statistics.

RESULTS

300 patients were identified, 265 met inclusion criteria. Median follow up was 56 months. Pelvic lymphadenectomy (PLND) was performed in 71%, with the remainder undergoing combined para-aortic dissection (PPaLND). Baseline patient demographics and presence of clinical risk factors were well balanced between groups. PPaLND was more common in patients undergoing open surgery (OR 10.58, p <.0001), and tumors were larger in this group (2.96 vs 2.12 cm, p = .0002) and more likely non-squamous histology (OR 2.02, p = .017). Recurrence of disease was present in 13% of cases, with no difference between PLND and PPaLND regardless of histology. There were zero cases of isolated PaLN recurrence in either group. Neither progression free nor overall survival was different between groups. Prophylactic extended field radiation (EFRT) was not prescribed.

CONCLUSION

Omission of PaLN dissection, in the absence of suspicious nodes, did not decrease survival. There were no isolated PaLN recurrences after PLND alone.

Impact of preoperative brachytherapy followed by radical hysterectomy in stage IB2 (FIGO 2018) cervical cancer: An analysis of SENTICOL I-II trials

INTRODUCTION

The goal of this study was to compare the outcomes of preoperative brachytherapy followed by radical surgery versus radical surgery alone in cervical cancer with tumor between 2 and 4 cm (FIGO 2018 IB2).

MATERIAL AND METHODS

SENTICOL I and SENTICOL II were two French prospective multicentric trials evaluating sentinel node biopsy in early-stage cervical cancer between 2005 and 2012. Preoperative brachytherapy (low-dose rate or pulse-dose rate at the dose of 60Gy) could be performed 6 to 8 weeks prior to the radical hysterectomy, at the discretion of each center. SENTICOL I and SENTICOL II cohorts were retrospectively analysed to compare the outcomes of preoperative brachytherapy or upfront surgery in patients with IB2 cervical tumor.

RESULTS

A total of 104 patients were included: 55 underwent upfront radical hysterectomy and 49 underwent preoperative brachytherapy followed by radical hysterectomy. Patients with preoperative brachytherapy were more likely to have no residual disease (71.4% vs. 25.5%, p < 0.0001) and to be defined as low risk according to Sedlis criteria (83.3% vs. 51.2%, p < 0.0001). Adjuvant treatments were required less frequently in case of preoperative brachytherapy (14.3% vs. 54.5%, p < 0.0001). Patients with preoperative brachytherapy experienced more postoperative complications grade ≥ 3 (24.5% vs. 9.1%, p = 0.03). Patients with preoperative brachytherapy had better 5-year disease-free survival compared to patients who underwent surgery alone, 93.6% and 74.4% respectively (p = 0.04).

CONCLUSION

Although preoperative brachytherapy was significantly associated with more severe postoperative complications, better pathologic features were obtained on surgical specimens and led to a better 5-year disease-free survival in IB2 cervical cancer.

Clinical analysis of 312 patients with stage IB1-IIA2 cervical squamous cell carcinoma and research on the influencing factors of postoperative recurrence

OBJECTIVE

To investigate the influencing factors of the recurrence of IB1-IIA2 cervical squamous cell carcinoma after surgical treatment, and to explore the relationship between high-risk human papillomavirus (HR-HPV) infection and postoperative cervical squamous cell carcinoma recurrence.

METHODS

Patients (n = 312) diagnosed with stage IB1-IIA2 cervical cancer and treated by radical hysterectomy and lymphadenectomy at this hospital were accrued between January 2014 and December 2016. The clinical data of these patients were analysed, and the association among clinicopathological factors, the association among clinicopathological factors, HPV infection and recurrences was investigated through Cox regression.

RESULTS

The median follow-up time was 59.2 months (with a range of 14-77.9 months). The pre-operative HPV infection rate was 85.3% (266/312), and 74 patients had a high level of HPV-DNA (> 5 × 10⁶ copy number / 10⁴ cells). Twenty-nine patients had a postoperative persistent high level of HPV-DNA (9.3%). On multivariate analysis, deep 1/3 stromal invasion (hazard ratio [HR] 114.79, 95% confidence interval [CI] 2.821-4670.111, p = 0.012*) and postoperative persistence of high HPV-DNA levels within 12 months (HR 269.044, 95% CI 14.437-5013.754, p < 0.001*) and 24 months (HR 31.299, 95% CI 1.191-822.215, p = 0.039*) were associated with a higher local recurrence rate.

CONCLUSION

Continuous high HPV-DNA levels within 24 months of an operation and deep 1/3 interstitial infiltration were independent risk factors for local recurrences of cervical cancer.

Effect of annualized surgeon volume on major surgical complications for abdominal and laparoscopic radical hysterectomy for cervical cancer in China, 2004-2016: a retrospective cohort study

BACKGROUND

Previous studies have suggested that higher surgeon volume leads to improved perioperative outcomes for oncologic surgery; however, the effect of surgeon volumes on surgical outcomes might differ according to the surgical approach used. This paper attempts to evaluate the effect of surgeon volume on complications or cervical cancer in an abdominal radical hysterectomy (ARH) cohort and laparoscopic radical hysterectomy (LRH) cohort.

METHODS

We conducted a population-based retrospective study using the Major Surgical Complications of Cervical Cancer in China (MSCCCC) database to analyse patients who underwent radical hysterectomy (RH) from 2004 to 2016 at 42 hospitals. We estimated the annualized surgeon volumes in the ARH cohort and in the LRH cohort separately. The effect of the surgeon volume of ARH or LRH on surgical complications was examined using multivariable logistic regression models.

RESULTS

In total, 22,684 patients who underwent RH for cervical cancer were identified. In the abdominal surgery cohort, the mean surgeon case volume increased from 2004 to 2013 (3.5 to 8.7 cases) and then decreased from 2013 to 2016 (8.7 to 4.9 cases). The mean surgeon case volume number of surgeons performing LRH increased from 1 to 12.1 cases between 2004 and 2016 (P < 0.01). In the abdominal surgery cohort, patients treated by intermediate-volume surgeons were more likely to experience postoperative complications (OR = 1.55, 95% CI = 1.11-2.15) than those treated by high-volume surgeons. In the laparoscopic surgery cohort, surgeon volume did not appear to influence the incidence of intraoperative or postoperative complications (P = 0.46; P = 0.13).

CONCLUSIONS

The performance of ARH by intermediate-volume surgeons is associated with an increased risk of postoperative complications. However, surgeon volume may have no effect on intraoperative or postoperative complications after LRH.

Role of laparoscopic hysterectomy in cervical and endometrial cancer: a narrative review

Endometrial cancer is the most common carcinoma of the female genital organs and cervical cancer is the leading cause of cancer death in women worldwide. The aim of this review is to evaluate the role of laparoscopic hysterectomy in patients with endometrial and cervical cancer in this period, and analyze the outcome of hysterectomy in terms of survival. Moreover, we present the historical background, new techniques, the anatomical features, and surgical steps of radical hysterectomy. According to new evidence, minimally invasive surgery in patients with cervical cancer is associated with higher rates of recurrence and mortality compared to the open approach. Despite the numerous explanations offered for this phenomenon, the reasons for these results are unclear. Additional large trials have been launched to reevaluate the above-mentioned data. On contrary, the laparoscopic approach provides surgical outcomes and similar survival rates as open surgery in patients with early endometrial carcinoma. Furthermore, the radicality of hysterectomy does not influence local recurrence rates or overall survival in cases with complete surgical removal of the tumor. A laparoscopic radical hysterectomy is no longer an option in patients with cervical cancer. When minimally invasive surgery is offered, the patients must be counseled in detail about the current debate.

Spontaneous bladder rupture attributable to a radical hysterectomy-associated neurogenic bladder in patients with cervical cancer: A case report and literature review

INTRODUCTION AND IMPORTANCE

Spontaneous bladder rupture (SBR) is an extremely rare urological emergency. Herein we report a rare case of SBR in a postoperative cervical cancer patient, which was attributable to bladder distension due to a radical hysterectomy-associated neurogenic bladder.

CASE PRESENTATION

A 74-year-old nulliparous Japanese patient with cervical cancer (pT1b3N0M0) presented with acute abdominal pain nine days after a radical hysterectomy. The pretreatment workup included plain computed tomography (CT) revealed the presence of ascites in the absence of gastrointestinal perforation. The patient was initially diagnosed with generalized bacterial peritonitis and treated with antibiotics. Urine outflow was noted 5 days later from the vaginal stump. Subsequent contrast-enhanced CT demonstrated a bladder wall defect with presence of contrast medium in the abdominal cavity. The patient was diagnosed with SBR and was conservatively treated with antibiotics and prolonged catheterization (4 weeks); these measures showed no signs of therapeutic efficacy. The patient was subsequently treated surgically with an ileal conduit urinary diversion. The patient is currently free of disease.

CLINICAL DISCUSSION

A literature review revealed that a history of pelvic radiotherapy is the main predisposing factor for SBR in women with cervical cancer. Our case serves to alert physicians that SBR should be considered a differential diagnosis in postoperative cervical cancer patients without a history of pelvic radiotherapy who experience generalized peritonitis symptoms or present as an acute abdomen.

CONCLUSION

SBR can develop in cervical cancer patients without a history of radiotherapy. This differential diagnosis should be considered in patients with a radical hysterectomy-associated neurogenic bladder.

Survival after laparoscopic radical surgery for stage IA-IIB cervical cancer: 1316 consecutive cases from a national laparoscopic training center in China

BACKGROUND

To investigate the survival of cervical cancer patients undergoing laparoscopic radical hysterectomy (LRH) in a minimally invasive gynecology center.

METHODS

A consecutive series of patients undergoing first LRH for cervical cancer from May 2008 to December 2017 at a national laparoscopic training center was retrospectively analyzed. The overall survival (OS) and progression-free survival (PFS) were compared between groups.

RESULTS

In total, 1316 women with FIGO (2009) stage IA-IIB cervical cancer received LRH. Among them, 1114 (84.7%) were followed up for 3 months or longer; the median follow-up period was 48 months (range 3-144 months). In patients with stage IA, IB1 (≤ 2 cm), IB1 (> 2 cm), IB2, IIA1 and IIA2-IIB tumors, the 4-year PFS rates were 98.6, 94.5, 87.4, 65.6, 80.0 and 67.4%, respectively, and the 4-year OS rates were 98.6, 96.8, 91.1, 77.4, 85.6 and 76.2%, respectively. The 4-year PFS and OS were as high as 96.2 and 97.5%, respectively, in patients with squamous cell carcinoma of 2 cm or smaller in diameter. A stable high 4-year OS and PFS was achieved after completing 100 LRHs. In patients operated on by the same surgeon, an improvement in survival was observed after 40 LRHs.

CONCLUSION

Favorable oncologic outcomes can be achieved in patients with IA-IB1 cervical cancer after LRH in a center with a high surgery volume.

Comparison of long-term bowel symptoms after laparoscopic radical hysterectomy versus abdominal radical hysterectomy in patients with cervical cancer

INTRODUCTION AND HYPOTHESIS

The objective of this study was to compare the long-term bowel symptoms between laparoscopic radical hysterectomy (LRH) and abdominal radical hysterectomy (ARH) in patients with cervical cancer.

METHODS

A total of 207 patients who underwent radical hysterectomy (79 underwent LRH and 128 underwent ARH) at Peking University First Hospital from January 2010 to August 2020 were enrolled and their bowel symptoms were investigated using the Colorectal Anal Distress Inventory-8 (CRADI-8) of the Pelvic Floor Distress Inventory-20. The prevalence and severity of bowel symptoms were compared in the LRH and ARH groups, and multivariate analysis was performed to determine the factors associated with bowel symptoms.

RESULTS

There was no difference in the CRADI-8 scores between the two groups. However, the prevalence of straining at stool was significantly higher in the ARH group than in the LRH group (19.5% versus 1.3%, p<0.001), and the score was significantly higher in the ARH group than in the LRH group too (0.4 versus 0, p<0.001). The prevalence of incomplete defecation was significantly higher in the ARH group than in the LRH group (13.3% versus 3.8%, p=0.029), and the ARH group also had a significantly higher score than the LRH group (0.3 versus 0.1, p=0.028). Multivariate analysis showed that ARH and postoperative interval were independent risk factors for the development of straining at stool.

CONCLUSIONS

Patients with cervical cancer who underwent ARH may be more likely to develop symptoms related to constipation than those who underwent LRH. This finding has to be interpreted with caution owing to the study design.

Surgical and oncologic outcomes between laparoscopic and radical abdominal hysterectomy for IB1-IIA2 cervical cancer

OBJECTIVE

To compare sugrical and survival outcomes between laparoscopic radical hysterectomy (LRH) and radical abdominal hysterectomy (RAH).

METHODS

All the patients with IB1-IIA2 cervical cancer who performed LRH or RAH in Fudan University Shanghai Cancer Center between 1/2016 and 12/2017 were retrospectively analyzed.

RESULTS

There were no significant differences between LRH and RAH groups except deep stromal invasion (35.2% vs 54.4%, p = 0.000), operating time (232.3 ± 61.9 min vs. 106.7 ± 36.2 min, p = 0.000), blood loss (169.5 ± 96.2 ml vs. 219.6 ± 149.3 ml, p = 0.000), and lymph node counts (21.1 ± 7.1 vs. 23.2 ± 8.7 min, p = 0.012). The LRH group displayed poorer disease-free survival (DFS) (5-year rate, 79.4% vs. 90.0%; p = 0.046) and overall survival (OS) (5-year rate, 74.7% vs. 90.0%; p = 0.026) compared to the RAH group. On multivariate analysis, LRH was an independent risk factor for DFS (hazard ratio, 0.377; 95% confidence interval [CI], 0.227-0.625; p = 0.000) and OS (hazard ratio, 0.434; 95% CI, 0.254-0.740; p = 0.003).

CONCLUSIONS

LRH affected the survival of cervical cancer patients with tumor size >2 cm (p < 0.05). Adjuvant therapy could not improve the prognosis of laparoscopic patients (p < 0.05).

Complications of radical hysterectomy with pelvic lymph node dissection for cervical cancer: a 10-year single-centre clinical observational study

BACKGROUND AND PURPOSE

The complications of radical surgery for cervical cancer can increase patient suffering and affect their quality of life. This retrospective study assessed the safety of radical hysterectomy (RH) with pelvic lymph node dissection (PLND) by observing the complications of patients with cervical cancer who underwent this procedure in a single centre over 10 years. Our findings may provide experience and evidence for preventing and reducing complications.

METHODS

A total of 2226 cervical cancer patients who met the inclusion criteria were enrolled. All patients underwent RH + PLND. Intraoperative injury to adjacent tissues and short-term and long-term complications were recorded to analyze factors associated with the occurrence of complications.

RESULTS

Postoperative complications occurred in 34.41% (766/2226) of patients, including 7.68% of patients with injury to adjacent tissues, 31.45% with short-term complications, and 2.96% with long-term complications. Age, tumor size, invasion depth, parametrial invasion, lymph vascular space invasion (LVSI), lymph node metastasis, International Federation of Gynaecology and Obstetrics (FIGO) stage, and surgical procedure were closely associated with the postoperative complications of RH + PLND (P < 0.05).

CONCLUSIONS

The results of this study showed that RH + PLND for cervical cancer is safe and practical. Patients aged 40-60 years, with tumors ≥ 4 cm, invasion depth ≥ 2/3, parametrial invasion, LVSI, lymph node metastasis, FIGO stage > IB2, and who underwent open surgery were more prone to complications.

Effectiveness of Low-Frequency Electrical Stimulation for Radical Hysterectomy Women: Systematic Review and Meta-Analysis

INTRODUCTION

The aim of the study was to explore the effects of low-frequency electrical stimulation (LFES) in preventing urinary retention after radical hysterectomy (RH) in women with cervical cancer.

METHODS

Seven electronic bibliographic databases were searched from inception to December 25, 2021. The mean difference (MD) or risk ratio (RR) with its corresponding 95% CI was selected as effect size. The meta-analysis of all data was conducted using RevMan 5.4 and the evidence was summarized according to GRADE (the grading of recommendation, assessment, development, and evaluation).

RESULTS

Twelve randomized control trials consisting of 1,033 women with cervical cancer who had undergone RH were included. Compared with women in the control group, women receiving LFES had improved therapeutic effect (RR = 0.22, 95% CI: 0.16-0.29) and reduced residual urine volume (MD = -32.27, 95% CI: -34.10 to -30.43) and catheter retention time (MD = -4.46, 95% CI: -5.17 to -3.76) following treatment. Muscle strength scores of pelvic floor type I and type II muscle fibers in the LFES group were also higher than in the control group (MD = 1.07, 95% CI: 0.91-1.24).

CONCLUSION

LFES may be an effective auxiliary treatment for women with cervical cancer after hysterectomy, which can help reduce the duration of indwelling urethral catheter and residual urine volume.

Locally advanced cervical rhabdomyosarcoma in adults: A case report

BACKGROUND

Rhabdomyosarcoma is a soft tissue tumor of primitive mesenchymal cells origin, occurring predominantly in children and adolescents, but extremely rare in adults and the data regarding its treatment are sparse. Here, we would like to share our experience in the treatment of a locally advanced primary embryonal rhabdomyosarcoma of cervix in a 39-year-old female.

CASE SUMMARY

The patient was admitted with symptoms of intermenstrual bleeding and postcoital bleeding for six months. Physical examination revealed a friable, polyp-like mass (5 cm × 5 cm) in her cervix protruding into the vagina, while the uterus was mobile and normal-sized. Colposcopy-directed biopsy was performed, and a pathological diagnosis of embryonal rhabdomyosarcoma was made. Magnetic resonance imaging of the pelvis showed that the cervical volume was significantly increased, with a hypointense and hyperintense soft tissue mass on the right side, invading the cervical stroma; the mass was 5 cm × 5 cm with a clear boundary and confined to the cervix; there were no obvious findings indicating tumor invasion in the vaginal wall, parametrium, or pelvic wall; no enlarged lymph nodes were observed in the pelvic cavity. Based on our findings, the tumor was classified as stage IA according to the intergroup rhabdomyosarcoma studies criteria and IB3 stage according to The International Federation of Gynecology and Obstetrics 2018. The patient underwent two courses of neoadjuvant chemotherapy and a partial remission was achieved. Subsequently, she underwent laparoscopic radical hysterectomy, bilateral salpingo-oophrectomy and pelvic lymph node dissection and there were no risk factors revealed by postoperative pathological examination. Adjuvant chemotherapy was performed after surgery. The patient was disease-free until the last follow-up, 49 mo after completing the entire treatment.

CONCLUSION

Our experience suggests that neoadjuvant vincristine, dactinomycin, and cyclophosphamide chemotherapy followed by radical surgery and adjuvant chemotherapy might be reasonable therapeutic option for bulky cervical rhabdomyosarcoma in adults without fertility desire. Since large-scale studies on such rare conditions are rather impossible, further case reports and systematic reviews could help optimize the treatment of primary, bulky cervical rhabdomyosarcoma in adults.

The MEMORY Study: MulticentEr study of Minimally invasive surgery versus Open Radical hYsterectomy in the management of early-stage cervical cancer: Survival outcomes

OBJECTIVE

The Laparoscopic Approach to Cervical Cancer (LACC) trial found that minimally invasive radical hysterectomy compared to open radical hysterectomy compromised oncologic outcomes and was associated with worse progression-free survival (PFS) and overall survival (OS) in early-stage cervical carcinoma. We sought to assess oncologic outcomes at multiple centers between minimally invasive (MIS) radical hysterectomy and OPEN radical hysterectomy.

METHODS

This is a multi-institutional, retrospective cohort study of patients with 2009 FIGO stage IA1 (with lymphovascular space invasion) to IB1 cervical carcinoma from 1/2007-12/2016. Patients who underwent preoperative therapy were excluded. Squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinomas were included. Appropriate statistical tests were used.

RESULTS

We identified 1093 cases for analysis-715 MIS (558 robotic [78%]) and 378. OPEN procedures. The OPEN cohort had more patients with tumors >2 cm, residual disease in the hysterectomy specimen, and more likely to have had adjuvant therapy. Median follow-up for the MIS and OPEN cohorts were 38.5 months (range, 0.03-149.51) and 54.98 months (range, 0.03-145.20), respectively. Three-year PFS rates were 87.9% (95% CI: 84.9-90.4%) and 89% (95% CI: 84.9-92%), respectively (P = 0.6). On multivariate analysis, the adjusted HR for recurrence/death was 0.70 (95% CI: 0.47-1.03; P = 0.07). Three-year OS rates were 95.8% (95% CI: 93.6-97.2%) and 96.6% (95% CI: 93.8-98.2%), respectively (P = 0.8). On multivariate analysis, the adjusted HR for death was 0.81 (95% CI: 0.43-1.52; P = 0.5).

CONCLUSION

This multi-institutional analysis showed that an MIS compared to OPEN radical hysterectomy for cervical cancer did not appear to compromise oncologic outcomes, with similar PFS and OS.

Practice patterns and 90-day treatment-related morbidity in early-stage cervical cancer

BACKGROUND

To evaluate the impact of the Laparoscopic Approach to Cervical Cancer (LACC) Trial on patterns of care and surgery-related morbidity in early-stage cervical cancer.

METHODS

This is a retrospective, a multi-institutional study evaluating 90-day surgery-related outcomes of patients undergoing treatment for early-stage cervical cancer before (period I: 01/01/2016-06/01/2018) and after (period II: 01/01/2019-06/01/2021) the publication of the results of the LACC trial.

RESULTS

Charts of 1295 patients were evaluated: 581 (44.9%) and 714 (55.1%) before and after the publication of the LACC trial, respectively. After the publication of the LACC trial, the number of patients treated with minimally invasive radical hysterectomy decreased from 64.9% to 30.4% (p < 0.001). Overall, 90-day complications occurred in 110 (18.9%) and 119 (16.6%) patients in the period I and period II, respectively (p = 0.795). Similarly, the number of severe (grade 3 or worse) complications did not differ between the two periods (38 (6.5%) vs. 37 (5.1%); p = 0.297). Overall and severe 90-day complications were consistent between periods even evaluating stage IA (p = 0.471), IB1 (p = 0.929), and IB2 (p = 0.074), separately.

CONCLUSIONS

The present investigation highlighted that in referral centers the shift from minimally invasive to open radical hysterectomy does not influence 90-day surgery-related morbidity.

Thirty-day Postoperative Adverse Events in Minimally Invasive versus Open Abdominal Radical Hysterectomy for Early-stage Cervical Cancer

STUDY OBJECTIVE

To identify the incidence, type, and grade of postoperative adverse events in minimally invasive radical hysterectomy vs abdominal radical hysterectomy (ARH) for patients with early-stage cervical cancer and determine risk factors associated with these adverse events.

DESIGN

The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) was queried to identify patients with early-stage cervical cancer undergoing radical hysterectomy. Multivariable logistic regression was used to assess risk factors associated with adverse postoperative outcomes among patients undergoing radical hysterectomy.

SETTING

ACS NSQIP participating institutions within the United States.

PATIENTS

Patients were collected from the ACS NSQIP databases (2014-2017) undergoing radical hysterectomy for early-stage cervical cancer.

INTERVENTIONS

N/A MEASUREMENTS AND MAIN RESULTS: ARH had a significantly increased incidence of any 30-day postoperative adverse event compared with minimally invasive radical hysterectomy (31.2% vs 19.9%, p <.001). There was a higher incidence of surgical site infection, both deep and superficial, and blood transfusions in ARH. On multivariable logistic regression, the abdominal surgical approach was the only risk factor significantly associated with any postoperative adverse event (odds ratio, 1.4; confidence interval, 1.1-1.9; p = .018; 95% CIs).

CONCLUSIONS

In this study, the abdominal surgical approach for radical hysterectomy in early-stage cervical cancer was associated with a higher incidence of postoperative adverse events than the minimally invasive approach.

Risk assessment in the patients with uterine cervical cancer harboring intermediate risk factors after radical hysterectomy: a multicenter, retrospective analysis by the Japanese Gynecologic Oncology Group

BACKGROUND

Adjuvant therapy is usually considered for surgically treated patients with uterine cervical cancer harboring intermediate risk (IR) factors such as large tumor diameter, stromal invasion to the outer half, and lymphovascular space invasion (LVSI). However, the indications and types of adjuvant therapy for the IR group remain controversial. This study aimed to analyze the differences in patient outcomes in the IR group to provide novel insights for tailoring adjuvant therapy.

METHODS

Data from 6192 patients with cervical cancer who underwent radical hysterectomy at 116 institutions belonging to the Japanese Gynecologic Oncology Group were reviewed.

RESULTS

In total, 1688 patients were classified into the IR group, of whom 37.3% did not receive adjuvant therapy. Conversely, approximately equal proportions of the remaining patients received adjuvant radiotherapy, concurrent chemoradiotherapy, and chemotherapy. Patients with all three risk factors showed worse overall survival than those with one or two risk factors. In addition to LVSI, non-squamous cell carcinoma histology, and vaginal invasion were identified as independent risk factors for both recurrence and mortality in multivariate analyses. Tumor diameter greater than 40 mm and surgical center volume were identified as independent risk factors for recurrence. Stromal invasion to the outer half and ovarian metastasis were identified as independent risk factors for mortality.

CONCLUSIONS

This study revealed the significant differences in prognosis in the IR group. The indications for adjuvant therapy should be further studied, focusing on conventional risk factors and other pathological findings.

Assessing the role of minimally invasive radical hysterectomy for early-stage cervical cancer

Surgery is the mainstay of treatment in the management of early-stage cervical cancer. Until the publication of the Laparoscopic Approach to Cervical Cancer (LACC) trial, minimally invasive radical hysterectomy was the recommended approach to treat patients with early-stage disease. The results of the LACC trial questioned the adoption of minimally invasive surgery in cervical cancer. In comparison with the open approach, minimally invasive surgery correlated with worse disease-free and cancer-specific survival. Similarly, other retrospective studies highlighted this correlation, thus corroborating the results of the LACC trials. In the present review, we evaluated current evidence and further prospective of the adoption of minimally invasive radical hysterectomy in cervical cancer. Moreover, we sought to assess some unsolved issues regarding the role of minimally invasive surgery in early-stage cervical cancer patients.

Protective effect of pre-operative conization in patients undergoing surgical treatment for early-stage cervical cancer

OBJECTIVE

The aim of this study was to investigate the impact of pre-operative conization on disease-free survival (DFS) in early-stage cervical cancer.

METHODS

In this population-based cohort study we analysed from clinical cancer registries to determine DFS of women with International Federation of Gynecology and Obstetrics (FIGO) stage IA1-IB1 cervical cancer with respect to conization preceding radical hysterectomy performed between January 2010 and December 2015.

RESULTS

Out of 993 datasets available for the analysis, 235 patients met the inclusion criteria of the current study. The median follow-up was 5.4 years. During the study period, 28 (11.9%) recurrences were observed. All of these occurred in patients with FIGO stage IB1. For further evaluation, patients with FIGO IB1 tumors <2 cm were further analysed and divided into two groups, based on pre-operative conization. Pre-operative conization was associated with a reduced rate of recurrence (p = 0.007), with only three (5.2%) recurrences in this group (CO) compared to 25 recurrences (21.0%) in the group without conization (NCO) preceding radical hysterectomy. DFS was estimated at 79.0% and 94.8% in NCO and CO, respectively (p = 0.008). After adjustment for other prognostic covariates, conization remained a favourable prognostic factor for DFS (HR 0.27; 95% CI 0.08-0.93, p = 0.037). Lymph node involvement was the only unfavourable factor (HR 4.38; 95% CI 1.36-14.14, p = 0.014) in the multivariable analysis.

CONCLUSIONS

Pre-operative conization is associated with improved DFS in early-stage cervical cancer independently of the surgical approach.

The best postoperative adjuvant therapy for patients with early stage cervical adenosquamous carcinoma

Background

Cervical adenosquamous carcinoma (ASC) was previously thought to be a subtype of cervical adenocarcinoma, but recent studies have found that the clinical features of the two diseases are different. Moreover, the pathological characteristics, survival, prognosis, and optimal ASC therapy remain unknown. This study aims to retrospectively analyze the postoperative survival of patients with early-stage ASC and to evaluate their condition after treatment with postoperative concurrent chemoradiotherapy (CCRT) and prophylactic irradiation of the para-aortic lymphatic drainage area.

Methods

This study enrolled 131 patients with pathologically confirmed ASC screened from 3502 patients with confirmed stage I–II cervical cancer diagnosis who had completed surgical treatments in our hospital. Among the 131 enrolled patients, 75 patients received CCRT, 33 patients received chemotherapy (CT), and 23 patients did not receive adjuvant treatment (named surgery alone (S alone). Of the 75 patients CCRT, 43 patients received prophylactic irradiation of the para-aortic lymphatic drainage area. The efficacy of the postoperative treatments of patients among groups (CCRT, CT, and S alone) was compared.

Results

The median follow-up time, age, and overall survival (OS) were 76 months, 43 years, and 74 months, respectively. The 3- and 5-year survival rates were 82% and 71.4%, respectively. The median disease-free survival (DFS) was 64 months. Cox regression analysis showed that postoperative adjuvant treatment modalities and positive lymph node metastases were associated with OS and DFS. Patients who received CCRT treatment had higher OS and DFS than those with CT and S alone. Prophylactic irradiation of the para-aortic lymphatic drainage area did not improve the OS and DFS of patients with CCRT treatment. However, further subgroup analysis suggested that it might improve survival rates in patients who had positive pelvic lymph nodes as confirmed by postoperative pathology.

Conclusion

Postoperative CCRT improved the survival rates in patients with early-stage ASC. The value of prophylactic irradiation of the para-aortic lymphatic drainage area remains debatable, but it may benefit patients with pelvic lymph node involvement.

Perceptions of pelvic floor dysfunction and rehabilitation care amongst women in southeast China after radical hysterectomy: a qualitative study

Objective

To investigate the perceptions of pelvic floor dysfunction (PFD) and rehabilitation care amongst women after radical hysterectomy and to explore ways to improve quality of care.

Methods

Thirty-six women who underwent radical hysterectomy at a hospital in southeast China were enrolled via purposive sampling. Semi-structured in-depth interviews were conducted. The texts were analysed via qualitative content analysis.

Results

Four themes were obtained: serious lack of knowledge, heavy psychological burden, different coping strategies and great eagerness to receive multiparty support on PFD rehabilitation care.

Conclusion

The society and professional staff should strengthen health education on PFD. Professionals should offer education before and after surgery and actively provide rehabilitation consultation to promote the availability of rehabilitation to support women with PFD rehabilitation care. In addition, family-centred care is an important way to support women to return to normal life, and women's need for family support should be more actively expressed. Moreover, knowledge of medical insurance should be popularised, especially in rural areas in China.

Oncologic outcomes of patients with FIGO 2014 stage IB-IIA cervical adenocarcinoma who underwent radical surgery

PURPOSE

To identify prognostic factors of early-stage cervical adenocarcinoma in patients with FIGO IB-IIA, who were treated with radical surgery.

MATERIALS AND METHODS

Clinical data of 64 patients with stage IB-IIA cervical adenocarcinoma who underwent radical hysterectomy and lymphadenectomy with or without adjuvant therapy between 1993 and 2019 were retrospectively reviewed. The clinicopathologic factors that affect the oncological outcomes were evaluated. The Kaplan-Meier method was used for the assessment of survival outcomes. Survival curves were compared using the log-rank test.

RESULTS

The 5-year recurrence-free survival and 5-year disease-specific survivals were 83% and 98%, respectively. Tumor size, stage of disease and uterine spread were significantly related prognostic factors for shorter recurrence-free survival. During the follow-up, nine (14.1%) patients recurred. Five of them were extrapelvic recurrence. No correlation was identified between histopathologic subtype and extrapelvic recurrence (p = 0.265). There was no difference between adjuvant only radiotherapy and concurrent chemoradiotherapy on recurrence-free survival in a univariate analysis adjusting for prognostic factors.

CONCLUSION

It is important to determine the prognostic factors that predict disease outcome in surgically treated cervical adenocarcinoma for tailored adjuvant treatment. Tumor size, stage and uterine spread are determinant factors for recurrence. Risk stratifications, including uterine spread may especially be useful for patients with AC.

Intraoperative near-infrared fluorescence imaging can identify pelvic nerves in patients with cervical cancer in real time during radical hysterectomy

Purpose

Radical hysterectomy combined with pelvic lymphadenectomy is the standard treatment for early-stage cervical cancer, but unrecognized pelvic nerves are vulnerable to irreversible damage during surgery. This early clinical trial investigated the feasibility and safety of intraoperative near-infrared (NIR) fluorescence imaging (NIR-FI) with indocyanine green (ICG) for identifying pelvic nerves during radical hysterectomy for cervical cancer.

Methods

Sixty-six adults with cervical cancer were enrolled in this prospective, open-label, single-arm, single-center clinical trial. NIR-FI was performed in vivo to identify genitofemoral (GN), obturator (ON), and hypogastric (HN) nerves intraoperatively. The primary endpoint was the presence of fluorescence in pelvic nerves. Secondary endpoints were the ICG distribution in a nerve specimen and potential underlying causes of fluorescence emission in pelvic nerves.

Results

In total, 63 patients were analyzed. The ON was visualized bilaterally in 100% (63/63) of patients, with a mean fluorescence signal-to-background ratio (SBR) of 5.3±2.1. The GN was identified bilaterally in 93.7% (59/63) of patients and unilaterally in the remaining 4 patients, with a mean SBR of 4.1±1.9. The HN was identified bilaterally in 81.0% (51/63) of patients and unilaterally in 7.9% (5/63) of patients, with a mean SBR of 3.5±1.3. ICG fluorescence was detected in frozen sections of a nerve specimen, and was mainly distributed in axons. No ICG-related complications were observed.

Conclusion

This early clinical trial demonstrated the feasibility and safety of NIR-FI to visualize pelvic nerves intraoperatively. Thus, NIR-FI may help surgeons adjust surgical decision-making, avoid nerve damage, and improve surgical outcomes.

Radical Hysterectomy for Cervical Cancer: the Right Surgical Approach

OPINION STATEMENT

Radical hysterectomy with pelvic lymph node assessment is the standard initial therapy for early-stage cervical cancer. Radical hysterectomy via laparotomy (an "open" approach) was first described more than 100 years ago and has been the standard for decades. Minimally invasive surgery (MIS) has been increasingly adopted by many surgeons due to its reported perioperative benefits. MIS was deemed safe for radical hysterectomy for many years based on multiple retrospective publications. Recently, the Laparoscopic Approach to Cervical Cancer (LACC) trial reported that patients randomized to MIS had inferior oncologic outcomes. The results of the LACC trial and subsequent retrospective studies led multiple professional societies to state that open radical hysterectomy should remain the gold standard surgical approach. We acknowledge that the open approach for radical hysterectomy is an appropriate option for all cervical cancer patients eligible for surgical treatment. However, considering the limitations of the LACC trial and the available data from other retrospective studies, we feel the MIS approach should not be simply abandoned. There may still be a role for MIS in cervical cancer surgery for properly and carefully selected cases and with detailed counseling; surgeons should analyze their own outcomes closely in order to perform such counseling. Modification of surgical technique and maintaining proper oncologic surgical principles are key for MIS to remain a viable option. Tumor manipulation and contamination should be avoided. Transcervical uterine manipulators should not be used. Cervical and tumor containment prior to colpotomy, as is performed during an open approach, is required. This will all require validation in future trials. We await the results of ongoing randomized trials to further inform us. A one-size-fits-all approach may be short-sighted; we may need to decide treatment strategy based on the notion of the right surgical approach for the right patient by the right surgeon.

Preoperative high-dose-rate brachytherapy for high-risk early-stage cervical cancer: Long-term clinical outcome analysis

OBJECTIVE

To report long-term oncological and toxicity outcomes after high-dose-rate brachytherapy (HDB) followed by oncologic surgery for patients with early-stage cervical cancer.

METHODS AND MATERIALS

From 2005 to 2019, all patients treated with preoperative HDB at Antoine Lacassagne Cancer Center for early-stage (IB1-IB2-IIA - FIGO 2018) cervical cancer with local relapse risk factors were included. HDB was performed followed by hysterectomy. Oncological and toxicity outcomes were evaluated prospectively.

RESULTS

We identified 61 patients, with a median follow-up of 84 months. Posthysterectomy complete pathological response was observed in 46 patients (75.4%). Six patients (9.8%) experienced recurrence, including 4 local relapses (6.6%), and 2 deaths (3.3%) due to cervical cancer. Five-year local, nodal and metastatic relapse-free survivals were 94% (95% CI 87-100%), 96% (95% CI 90-100%) and 93% (95% CI 86-100%) respectively. Five-year overall survival was 98% (95% CI 95-100%). No grade ≥ 3 acute toxicity was observed, and 3 patients (4.9%) experienced grade 2 acute toxicity. One patient presented grade 4 late digestive toxicity, and 6 patients had grade 2 late toxicity. Only 1 patient still had grade 2 toxicity, after 9 years follow-up.

CONCLUSIONS

To our knowledge, we are reporting the longest follow-up of a preoperative HDB cohort. With similar oncological outcomes and less morbidity compared to primary surgery treatment followed more or less by adjuvant radiotherapy, HDB followed by hysterectomy could be a promising therapeutic option for early-stage cervical cancers with poor prognostic factors.

Cervical conization before primary radical hysterectomy has a protective effect on disease recurrence in early cervical cancer: A two-center matched cohort study according to surgical approach

OBJECTIVE

To ascertain whether cervical conization before radical hysterectomy (RH) has a protective effect on survival outcomes in early cervical cancer, taking into account the surgical approach.

METHODS

From cervical cancer cohorts of two institutions, we identified node-negative, margin-negative, parametria-negative, 2009 FIGO stage IB1 cervical cancer patients who received primary Type C RH between July 2006 and June 2020. Patients were divided into conization group (n = 144) and control group (n = 434). We conducted three independent 1:1 propensity score matching processes for histology, lymphovascular space invasion, cervical tumor size, and surgical approach (all patients, those who underwent open surgery, and those who underwent minimally invasive surgery [MIS]). Survival outcomes were compared.

RESULTS

Overall, the conization group had less cervical tumor size and received MIS more frequently (P = 0.010) and adjuvant treatment less often (P = 0.002) versus the controls. After matching, the conization group showed significantly better disease-free survival (DFS) versus control (3-year DFS rate, 94.2% vs. 86.3%; P = 0.012), but similar overall survival. Among the open RH matched patients (n = 96), no difference in DFS was observed between the conization and control groups (P = 0.984). In contrast, among the MIS RH matched patients (n = 192), the conization group showed significantly better DFS versus control (3-year DFS rate, 95.7% vs. 82.9%; P = 0.005). In multivariate analysis adjusting for cervical tumor size and adjuvant treatment, conization was identified as an independent favorable prognostic factor for DFS (adjusted HR, 0.318; 95% CI, 0.134-0.754; P = 0.009).

CONCLUSIONS

Preoperative cervical conization might reduce the disease recurrence rate in early cervical cancer patients who undergo primary MIS RH.

Laparoscopic nerve‑sparing radical hysterectomy for the treatment of cervical cancer: a meta-analysis of randomized controlled trials

Background

The effects and safety of laparoscopic nerve‑sparing radical hysterectomy (LNSRH) and laparoscopic radical hysterectomy (LRH) in cervical cancer treatment remain unclear. This article aims to evaluate the role of LNSRH versus LRH in the treatment of cervical cancer. This is because the updated meta-analysis with synthesized data may provide more reliable evidence on the role of LNSRH and LRH.

Methods

We searched Pubmed et al. databases for randomized controlled trials (RCTs) involving laparoscopic nerve‑sparing radical hysterectomy (LNSRH) and laparoscopic radical hysterectomy (LRH) for cervical cancer treatment from the inception of databases to June 15, 2021. The RevMan 5.3 software was used for data analyses. This meta-analysis protocol had been registered online (available at: https://inplasy.com/inplasy-2021-9-0047/).

Results

Thirteen RCTs involving a total of 1002 cervical cancer patients were included. Synthesized results indicated that the duration of surgery of the LNSRH group was significantly longer than that of the LRH group [SMD 1.11, 95% CI (0.15 ~ 2.07), P = 0.02]. The time to intestinal function recovery [SMD −1.27, 95% CI (−1.84 ~ −0.69), P < 0.001] and the time to postoperative urinary catheter removal of the LNSRH group [SMD −1.24, 95% CI (−1.62 ~ −0.86), P < 0.001] were significantly less than that of the LRH group. There were no significant differences in the estimated blood loss [SMD 0.10, 95% CI (−0.14 ~ 0.34), P = 0.41], the length of parauterine tissue resection [SMD −0.10, 95% CI (−0.25 ~ 0.05), P = 0.19], length of vaginal excision [SMD 0.04, 95% CI (−0.26 ~ 0.34), P = 0.78], and incidence of intraoperative adverse events [RR 0.97, 95% CI (0.44 ~ 2.13), P = 0.94] between the LNSRH group and the LRH group.

Conclusions

LNSRH significantly results in earlier bladder and bowel function after surgery. Limited by sample size, LNSRH should be considered with caution in the future.

Perioperative morbidity of different operative approaches in early cervical carcinoma: a systematic review and meta-analysis comparing minimally invasive versus open radical hysterectomy

Purpose

Radical hysterectomy and pelvic lymphadenectomy is the standard treatment for early cervical cancer. Studies have shown superior oncological outcome for open versus minimal invasive surgery, but peri- and postoperative complication rates were shown vice versa. This meta-analysis evaluates the peri- and postoperative morbidities and complications of robotic and laparoscopic radical hysterectomy compared to open surgery.

Methods

Embase and Ovid-Medline databases were systematically searched in June 2020 for studies comparing robotic, laparoscopic and open radical hysterectomy. There was no limitation in publication year. Inclusion criteria were set analogue to the LACC trial. Subgroup analyses were performed regarding the operative technique, the study design and the date of publication for the endpoints intra- and postoperative morbidity, estimated blood loss, hospital stay and operation time.

Results

27 studies fulfilled the inclusion criteria. Five prospective, randomized-control trials were included. Meta-analysis showed no significant difference between robotic radical hysterectomy (RH) and laparoscopic hysterectomy (LH) concerning intra- and perioperative complications. Operation time was longer in both RH (mean difference 44.79 min [95% CI 38.16; 51.42]), and LH (mean difference 20.96 min; [95% CI − 1.30; 43.22]) than in open hysterectomy (AH) but did not lead to a rise of intra- and postoperative complications. Intraoperative morbidity was lower in LH than in AH (RR 0.90 [0.80; 1.02]) as well as in RH compared to AH (0.54 [0.33; 0.88]). Intraoperative morbidity showed no difference between LH and RH (RR 1.29 [0.23; 7.29]). Postoperative morbidity was not different in any approach. Estimated blood loss was lower in both LH (mean difference − 114.34 [− 122.97; − 105.71]) and RH (mean difference − 287.14 [− 392.99; − 181.28]) compared to AH, respectively. Duration of hospital stay was shorter for LH (mean difference − 3.06 [− 3.28; − 2.83]) and RH (mean difference − 3.77 [− 5.10; − 2.44]) compared to AH.

Conclusion

Minimally invasive radical hysterectomy appears to be associated with reduced intraoperative morbidity and blood loss and improved reconvalescence after surgery. Besides oncological and surgical factors these results should be considered when counseling patients for radical hysterectomy and underscore the need for new randomized trials.

Vaginal-assisted gasless laparoendoscopic single-site radical hysterectomy for early cervical cancer: a retrospective pilot study

Background

Minimally invasive surgery for early cervical cancer is debated. We developed this new vaginal-assisted gasless laparoendoscopic single-site radical hysterectomy for early cervical cancer, and we aimed to evaluate the feasibility and safety of this surgical procedure and observe the early oncologic outcomes.

Methods

From January 2019 to August 2020, patients with early cervical cancer who underwent vaginal-assisted gasless laparoendoscopic single-site radical hysterectomy were studied retrospectively. The clinical characteristics, pathologic outcomes, perioperative outcomes, and follow-up details of the patients were recorded.

Results

Forty-eight patients underwent vaginal-assisted gasless laparoendoscopic single-site radical hysterectomy were included, 14 (29.2%) with stage IB1, 13 (27.1%) with stage IB2, 7 (14.6%) with stage IB3, 10 (20.8%) with stage IIA1, and 4 (8.3%) stage with IA2. The mean age at diagnosis was 50.4 (range 28–72) years old. The mean operative time was 237.3 min (range 162–393), and the mean estimated blood loss was 246.5 ml (range 80–800). No intraoperative complications occurred, and there were no patients who were readmitted. Histological types were distributed as follows: squamous cell carcinoma 72.9%, adenocarcinoma 10.4%, and adenosquamous cell carcinoma 16.7%. There were 2 patients (4.2%) with positive nodes, 20 patients (41.7%) with positive lymphovascular space invasion, and 2 patients (4.2%) with positive parametria. Twenty-eight patients (58.3%) received adjuvant therapy after the operation. With a mean follow-up of 17.7 months (range 6–26), there were no recurrent cases, and 11 patients (22.9%) suffered lower limb lymphoedema.

Conclusions

The vaginal-assisted gasless laparoendoscopic single-site radical hysterectomy might be a feasible technique for early cervical cancer, with promising short-term oncological outcomes and safety. A prospective study with more patients and longer follow-up periods should be performed to further evaluate the safety and oncological outcomes.

Surveillance of radical hysterectomy for early-stage cervical cancer in the early experienced period of minimally invasive surgery in Japan

OBJECTIVE

The purpose of our study was to conduct a detailed survey of radical hysterectomy in Japanese patients with early-stage cervical cancer, and to compare oncologic outcomes between open and minimally invasive radical hysterectomy.

METHODS

In Japan during 2015, the medical records of 929 patients with FIGO stage IB1 and IIA disease treated with radical hysterectomy were retrospectively reviewed. We assessed patients' characteristics, disease-free survival (DFS), overall survival (OS) and prognostic factors for survival.

RESULTS

The median patient age was 44 (20-80) years. Most patients (94.4%) had stage IB1 disease. Of the patients who underwent radical hysterectomy, 91.2% underwent open surgery and 8.8% underwent minimally invasive surgery (MIS). The median follow-up period was 40.8 months (range, 0.49-51.1 months). The rate of DFS and OS at 4 years in all patients was 88.3% and 96.4%, respectively. Multivariate analysis identified age (≥ 47), adenocarcinoma histology, tumor size (≥ 2 cm), parametrial invasion, positive lymph node metastasis and institutional accreditation as independent predictors of recurrence, and adenocarcinoma, other cell types, and positive lymph node metastasis as independent predictors of death. Oncologic outcomes in all patients were similar between open and MIS, including DFS and OS.

CONCLUSION

The survival rate of the Japanese patients underwent radical hysterectomy for early-stage cervical cancer was favorable. No significant differences were observed for DFS and OS between open and MIS performed by a limited number of surgeons at a limited number of facilities in Japan. Further investigations are required to identify the appropriate patients might benefit from MIS.
