Laparoscopically Assisted Vaginal Radical Hysterectomy: Systematic Review of the Literature

Effect of laparoscopic-assisted transvaginal hysterectomy on wound complications in patients with early stage cervical cancer: A meta-analysis

Laparoscopic-assisted vaginal radical hysterectomy (LARVH) and abdominal radical hysterectomy (ARH) have been widely applied to treat cervical carcinoma. But LARVH and ARH have not been fully investigated in treating cervical carcinoma after injury associated with injury. This research is intended to provide an up-to-date basis for comparing LARVH with ARH in early stage cervical carcinoma. Comparison between LARVH and ARH in cervical carcinoma was carried out through a combination of related research. Eligible articles from databases such as PubMed and Embase were screened using an established search strategy. This report covered the results of LARVH versus ARH in cervical carcinoma. The average difference and the 95% confidence interval (CI) were used for the combination of consecutive variables. The combination of categorical variables was performed with the odds ratio (OR) 95% confidence interval. Through the identification of 1137 publications, eight of them were chosen to be analysed. Among them, 363 were treated with LARVH and 326 were treated with ARH. Eight trials showed that LARVH was associated with a reduced risk of postoperative wound infection than ARH (OR, 0.23; 95% CI, 0.1-0.55, p = 0.0009). Five trials showed that there was no difference in the risk of postoperative bleeding after surgery (OR, 1.17; 95% CI, 0.42-3.29, p = 0.76). We also did not differ significantly in the duration of the surgery (OR, 1.79; 95% CI, -6.58 to 10.15, p = 0.68). So, the two surgical methods differ significantly only in the risk of postoperative wound infection.

A meta-analysis examining the impact of open surgical therapy versus minimally invasive surgery on wound infection in females with cervical cancer

A meta-analysis study was executed to measure the effect of minimally invasive surgery (MIS) and open surgical management (OSM) on wound infection (WI) in female's cervical cancer (CC). A comprehensive literature study till February 2023 was applied and 1675 interrelated investigations were reviewed. The 41 chosen investigations enclosed 10 204 females with CC and were in the chosen investigations' starting point, 4294 of them were utilizing MIS, and 5910 were utilizing OSM. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were utilized to compute the value of the effect of MIS and OSM on WI in female's CC and by the dichotomous approaches and a fixed or random model. The MIS had significantly lower WI (OR, 0.23; 95% CI, 0.15-0.35, p < 0.001) with no heterogeneity (I2 = 0%) and postoperative aggregate complications (PACs) (OR, 0.49; 95% CI, 0.37-0.64, p < 0.001) in females with CC and compared OSM. However, MIS compared with OSM in females with CC and had no significant difference in pelvic infection and abscess (PIA) (OR, 0.59; 95% CI, 0.31-1.16, p = 0.13). The MIS had significantly lower WI, and PACs, though, had no significant difference in PIA in females with CC and compared with OSM. However, care must be exercised when dealing with its values because of the low sample size of some of the nominated investigations for the meta-analysis.

Effect of minimally invasive surgery and laparotomy on wound infection and postoperative and intraoperative complications in the management of cervical cancer: A meta-analysis

We performed a meta-analysis to evaluate the effect of minimally invasive surgery and laparotomy on wound infection and postoperative and intraoperative complications in the management of cervical cancer. A systematic literature search up to July 2022 was performed and 10 231 subjects with cervical cancer at the baseline of the studies; 4307 of them were using the minimally invasive surgery, and 5924 were using laparotomy. Odds ratio (OR) with 95% confidence intervals (CIs) were calculated to assess the effect of minimally invasive surgery and laparotomy on wound infection and postoperative and intraoperative complications in the management of cervical cancer using the dichotomous methods with a random or fixed-effect model. The minimally invasive surgery had significantly lower wound infection (OR, 0.20; 95% CI, 0.13-0.30, P < .001), and postoperative complications (OR, 0.48; 95% CI, 0.37-0.64, P < .001) in subjects with cervical cancer compared laparotomy. However, minimally invasive surgery compared with laparotomy in subjects with cervical cancer had no significant difference in intraoperative complications (OR, 1.04; 95% CI, 0.80-1.36, P = 0.76). The minimally invasive surgery had significantly lower wound infection, and postoperative complications however, had no significant difference in intraoperative complications in subjects with cervical cancer compared with laparotomy. The analysis of outcomes should be with caution because of the low sample size of 22 out of 41 studies in the meta-analysis and a low number of studies in certain comparisons.

Radical Vaginal Trachelectomy

Recently, radical vaginal hysterectomy (RVH) has developed into laparoscopically assisted radical vaginal hysterectomy (LARVH), which is associated with the laparoscopical procedure, and it is applied as radical vaginal trachelectomy and semi-radical vaginal hysterectomy. LARVH is indicated for patients with stage IB1 and IIA1 cervical carcinoma, especially those with a tumor size of less than 2 cm, because the cardinal ligaments cannot be resected widely. Although RVH that is associated with laparoscopic pelvic lymphadenectomy is the most used surgical procedure, radical trachelectomy may be performed either abdominally or vaginally (laparoscopic or robotic). One report found that the pregnancy rate was higher in patients who underwent minimally invasive or radical vaginal trachelectomy than in those who underwent radical abdominal trachelectomy.

Minimal-invasive or open approach for surgery of early cervical cancer: the treatment center matters

PURPOSE

The aim of the study was to compare recurrence-free survival (RFS) and overall survival (OS) of patients with early stage cervical cancer in dependence of surgical approach and treatment center.

PATIENTS AND METHODS

A population-based cohort study including women with early stage IA1-IIB2 cervical cancer treated by radical hysterectomy between January 2010 and December 2015 was performed.

RESULTS

The median follow-up time was 5.6 years. After exclusions, 413 patients were eligible for analysis: 111 (26.9%) underwent minimal-invasive surgery (MIS) and 302 (73.1%) open surgery. Both treatment groups were well balanced regarding the clinical and pathological characteristics. The mean age of the patients was 51.0 years. MIS was associated with improved RFS and OS compared with the open surgery. The 5-year RFS rates were 89.2% in the MIS group and 73.4% in the open surgery group (p = 0.004). The 5-year OS rates were 93.7% in the MIS group and 81.8% in the open surgery group (p = 0.016). After adjustment for other prognostic covariates, the MIS was further associated with improved RFS (HR = 0.45, 95% CI 0.24-0.86; p = 0.015) but not with OS. Nevertheless, after adjustment for treatment center, the surgical approach was not associated with significant difference in RFS (HR = 0.61, 95% CI 0.31-1.19; p = 0.143). Overall survival of patients treated in university cancer centers was significantly increased compared to patients treated in non-university cancer centers. The treatment center remains a strong prognostic factor regarding RFS (HR = 0.49, 95% CI 0.28-0.83; p = 0.009) and OS (HR = 0.50, 95% CI 0.26-0.94; p = 0.031).

CONCLUSIONS

The treatment center but not the surgical approach was associated with the survival of patients treated with radical hysterectomy for early stage cervical cancer.

Oncologic Outcomes of Robotic Radical Hysterectomy (RRH) for Patients with Early-Stage Cervical Cancer: Experience at a Referral Cancer Center

PURPOSE

To evaluate oncologic outcomes of early stage cervical cancer patients who underwent robotic radical hysterectomy (RRH) in a referral center, a retrospective analysis was performed.

METHODS

From January 2010 to December 2018, medical records of stage IA2-IIA1 cervical cancer patients, who underwent radical hysterectomy at our institute, were retrospectively reviewed. We focused our analysis on those who underwent RRH.

RESULTS

A total of 198 patients were included in the final analysis. Median follow up was 52 months. At last follow-up, 188 (94.9%) women were disease-free, 9 (4.5%) had died, and 1 (0.5%) was alive with recurrent disease. At 4.5 years, PFS was 93.1% (SE ± 2.1) and OS was 95.1% (SE ± 1.8). Stratified by tumor size, PFS for tumor < 2 cm versus tumor ≥ 2 cm was statistically different (96.8% ± 2.3 and 87.9% ± 4.1 respectively, p = 0.01), as well as OS (100% and 89.8% ± 40 respectively, p = 0.01).Stratified by evidence of tumor at time of robotic surgery, PFS was statistically different in women with no residual tumor after conisation versus those with residual disease (100% ± 2.5 and 90.8% ± 2.8 respectively, p = 0.04). A recurrence occurred in 11 patients (5.6%).

CONCLUSIONS

Based on our results, we could speculate that robotic approach, along with some technical precautions to avoid spillage, might be safe as primary treatment of early-stage cervical cancer, especially for tumor < 2 cm and in case of no evidence of disease at time of radical hysterectomy after previous conisation.

Efficacy of different surgical approaches on survival outcomes in patients with early-stage cervical cancer: protocol for a multicentre longitudinal study in China

INTRODUCTION

Recent studies have revealed that the oncological survival outcomes of minimally invasive radical hysterectomy (MIRH) are inferior to those of abdominal radical hysterectomy (ARH) in early-stage cervical cancer, but the potential reasons are unclear.

METHODS AND ANALYSIS

Each expert from 28 study centres participating in a previously reported randomised controlled trial (NCT03739944) will provide successive eligible records of at least 100 patients who accepted radical hysterectomy for early-stage cervical cancer between 1 January 2009 and 31 December 2015. Inclusion criteria consist of a definite pathological evaluation of stages IA1 (with positive lymphovascular space invasion), IA2 and IB1 according to the International Federation of Gynecology and Obstetrics 2009 staging system and a histological subtype of squamous cell carcinoma, adenocarcinoma or adenosquamous carcinoma. The primary endpoint is 5-year disease-free survival between the MIRH and ARH groups. The secondary endpoints include the MIRH learning curves of participating surgeons, 5-year overall survival between the MIRH and ARH groups, survival outcomes according to surgical chronology, surgical outcomes and sites of recurrence and potential risk factors that affect survival outcomes. A subgroup analysis in patients with tumour diameter less than 2 cm will follow the similar flow diagram.

ETHICS AND DISSEMINATION

This study has been approved by the Institutional Review Board of Peking Union Medical College Hospital (registration no. JS-1711), and is also filed on record by all other 27 centres. The results will be disseminated through community events and peer-reviewed journals.

NCT03738969.

An Australian, single-centre study of surgical management outcomes for early-stage cervical cancer

BACKGROUND

The Laparoscopic Approach to Cervical Cancer (LACC) trial is the first phase III randomised, multicentred trial to compare oncologic outcomes associated with open radical hysterectomy vs minimally invasive surgery (MIS) for treatment of early cervical cancer.

AIM

To evaluate our surgical experience in patients with early cervical cancer.

METHODS AND MATERIALS

The Lifehouse Gynaecologic Oncology database was queried based upon the eligibility criteria of the LACC study and included all FIGO 2009 stage (1A1 with lymph vascular space invasion, 1A2, 1B1) cervical cancer women from 2008-2018. Patients were also included in our study if they had abdominal radical trachelectomy (ART), laparoscopic radical hysterectomy (TLRH) and robotic radical trachelectomy (RRT).

RESULTS

Forty-six women were identified with four exclusions. Thirty-seven women had stage 1B1 disease, 24 had a squamous cell carcinoma, 15 had an adenocarcinoma and three had an adenosquamous carcinoma of the cervix. Of the 42 eligible patients, 32 underwent an open abdominal approach (26 total abdominal radical hysterectomy (TARH), six ART) and ten a MIS approach (nine TLRH and one RRT) with a mean follow-up of 4.8 years. All 42 women had a pelvic lymph node dissection, eight women had nodal metastases and 16 patients received adjuvant chemoradiation. Two of the nine women in the laparoscopic radical hysterectomy group had a recurrence. Both had adenocarcinoma, stage 1B1 disease. There were no recurrences in the TARH group or radical trachelectomy groups.

CONCLUSION

Our data, albeit limited in number, have reflected the results of the LACC trial that MIS was associated with a lower disease-free survival than open radical hysterectomy.

Efficacy of different surgical approaches in the clinical and survival outcomes of patients with early-stage cervical cancer: protocol of a phase III multicentre randomised controlled trial in China

INTRODUCTION

In the last three decades, minimally invasive surgery (MIS) for radical hysterectomy (RH) has become a popular treatment option for early-stage cervical cancer. However, a recently published randomised controlled trial (LACC trial) and an epidemiological study in the USA revealed strong evidence against the survival advantage of MIS for RH. However, the influencing factors of research centres and the learning curves of surgeons in these studies lacked sufficient evaluation. The efficacy of different surgical approaches for early-stage cervical cancer in the clinical and survival outcomes remains to be validated.

METHODS AND ANALYSIS

Patients diagnosed with FIGO (2009) stage IA1 (with lymphovascular space invasion), IA2 or IB1 cervical cancer with histological subtype of squamous cell carcinoma, adenocarcinoma or adenosquamous carcinoma will be recruited in this multicentre randomised controlled study. Patients will be randomly assigned to undergo MIS (robot-assisted or laparoscopic RH) or abdominal RH. Within 2 years, 1448 patients in 28 centres in China will be recruited to meet the criteria of a non-inferiority threshold of HR of 1.6 with bilateral nominal α <0.05 and power of 0.8. All surgeries will be performed by the indicated experienced surgeons. At least 100 RH cases in the individual past one decade of practice will be analysed as proof of learning curves. The primary objective of this study is 5-year disease-free survival. The secondary objectives include the overall survival rate, progression-free survival rate, disease-free survival rate, cost-effectiveness and quality of life.

ETHICS AND DISSEMINATION

This study has been approved by the Institutional Review Board of Peking Union Medical College Hospital and is filed on record by all other centres. Written informed consent will be obtained from all eligible participants before enrolment. The results will be disseminated through community events, academic conferences, student theses and peer-reviewed journals.

Neoadjuvant chemotherapy followed by radical hysterectomy for stage IB2-to-IIB cervical cancer: a retrospective cohort study

INTRODUCTION

This study was to evaluate the surgical and survival effects of neoadjuvant chemotherapy (NAC) followed by radical hysterectomy (RH) for cervical cancer with stages IB2 to IIB of FIGO 2009 staging.

METHODS

From February 2, 2001 to November 11, 2015, 428 patients received NAC followed by RH in a tertiary hospital, in which all the major procedures were performed by one surgeon. Surgical and survival outcomes were evaluated between the NAC and primary RH groups.

RESULTS

A total of 279 (65.2%) patients received NAC, and the overall clinical and complete pathological response rates were 65.9% and 10.8%, respectively. Compared with primary RH patients, NAC patients had more advanced stages, higher recurrence rate, longer median duration of RH, and more median estimated blood loss. After adjusted with baseline risk factors, no significant differences in progression-free or overall survival were observed between the NAC and primary RH groups. However, the responders to NAC had better survival outcomes.

CONCLUSIONS

There were no surgical or survival benefits of NAC for patients with cervical cancer of stages IB2 to IIB except for the responders to NAC.

Laparoscopic procedure compared with open radical hysterectomy with pelvic lymphadenectomy in early cervical cancer: a retrospective study

Objective

To compare clinical outcomes in laparoscopic and open radical hysterectomy with pelvic lymphadenectomy (LRH) in early cervical cancer without the selection bias.

Methods

One special retrospective study was conducted with more than 400 patients involved in laparoscopic procedure.

Results

Our results suggest that estimated blood loss and transfusion requirements were significantly lower in the LRH group. Postoperative hospital stay was also significantly shorter in the LRH group. Significant difference was found in the number of pelvic lymph nodes retrieved between the LRH and open radical hysterectomy with pelvic lymphadenectomy (ORH) groups. There were no differences in operating time, perioperative complications, progression-free survival, and overall survival between the LRH and ORH groups.

Conclusion

LRH can be considered a safe and effective alternative to conventional open surgery (ORH) for early-stage cervical cancer.

Evolution of radical hysterectomy for cervical cancer along the last two decades: single institution experience

Background:

The radical hysterectomy (RH) surgical technique has improved along the years. It is used for the treatment of cervical cancer, endometrial cancer when affecting the cervix, and upper vaginal carcinomas. Our aim was to describe the historical evolution of the technique after the introduction of laparoscopy at our institution.

Methods:

We performed a retrospective review of medical records of patients who underwent RH, grouped in three periods according to the year of surgery: 1990-1999, 2000-2009 and 2010-2013. Patients?characteristics, pathologic details, intraoperative and postoperative complications were analyzed and compared throughout the time periods.

Results:

A total of 102 cases of RH were performed at our center during the study period. Among all data collected, the presence of necrosis, age, number of lymph nodes, surgery route, operating time, hospital stay, blood loss and transfusion requirement were statistically significant different among groups. Conversion to laparotomy rate was 19% for the second period compared to the absence of cases in the last one. No significant differences (P=0.124) were observed in the adjuvant treatment received among the three different groups. At the time of the last contact the patients free of disease were 12 (85.7%), 53 (91.3%) and 26 (86.6%) respectively (P=0.406). Regarding the disease-free interval, we found significant better outcomes in the group of laparotomy compared to laparoscopy (P=0.015).

Conclusions:

Laparoscopic RH is an acceptable surgery with advantages like magnified vision of the operation抯 field, lower surgical complications, shorter hospital stay and earlier resumption to daily activities.

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

IMPORTANCE

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

OBJECTIVE

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

EVIDENCE ACQUISITION

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

RESULTS

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

CONCLUSIONS AND RELEVANCE

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