Classification of radical hysterectomy adopted by the Gynecological Cancer Group of the European Organization for Research and Treatment of Cancer

Revisiting Querleu-Morrow Radical Hysterectomy: How to Apply the Anatomy of Parametrium and Pelvic Autonomic Nerves to Cervical Cancer Surgery?

In 2008, Querleu and Morrow proposed a novel classification of radical hysterectomy, which was quickly accepted by the professional oncogynecological community. The Querleu and Morrow (Q-M) classification of radical hysterectomy has provided a unique opportunity for uniform surgical and anatomical terminology. The classification offers detailed explanations of anatomical landmarks and resection margins for the three parametria of the uterus. However, there are still some disagreements and misconceptions regarding the terminology and anatomical landmarks of the Q-M classification. This article aims to highlight the surgical anatomy of all radical hysterectomy types within the Q-M classification. It discusses and illustrates the importance of anatomical landmarks for defining resection margins of the Q-M classification and reviews the differences between Q-M and other radical hysterectomy classifications. Additionally, we propose an update of the Q-M classification, which includes the implementation of parauterine lymphovascular tissue, paracervical lymph node dissection, and Selective-Systematic Nerve-Sparing type C2 radical hysterectomy. Type D was modified according to current guidelines for the management of patients with cervical cancer. The detailed explanation of the surgical anatomy of radical hysterectomy and the proposed update may help achieve surgical harmonization and precise standardization among oncogynecologists, which can further facilitate accurate and comparable results of multi-institutional surgical clinical trials.

Randomized Phase III Study Comparing Neoadjuvant Chemotherapy Followed by Surgery Versus Chemoradiation in Stage IB2-IIB Cervical Cancer: EORTC-55994

PURPOSE

This multicenter trial by the European Organisation for Research and Treatment of Cancer Gynecological Cancer Group was motivated by conflicting evidence on the value of neoadjuvant chemotherapy before surgery compared with concomitant chemoradiotherapy (CCRT) in stage IB2-IIB cervical carcinoma.

METHODS

Between May 2002 and January 2014, 626 patients with International Federation of Gynecology and Obstetrics stage IB2-IIb were randomly assigned between neoadjuvant chemotherapy followed by surgery (NACT-S; n = 314) and standard CCRT (n = 312). The primary end point was 5-year overall survival (OS) rate. Secondary end points were progression-free survival, OS, toxicity, and health-related quality of life (HRQOL).

RESULTS

After a median follow-up of 8.7 years, 198 patients (31.6%) died. Age, stage, and cell type were balanced in both arms. Protocol treatment was completed in 223 of 314 (71%) patients in NACT-S and 257 of 312(82%) in CCRT arms. Main reasons for incomplete protocol treatment were toxicity (30 of 314; 9.6%) and progressive disease (21 of 314; 6.7%) in the NACT-S arm and toxicity (23 of 312; 7.4%) and patient refusal (13 of 312; 4.2%) in the CCRT arm. Additional radiotherapy after completed NACT-S was given to 107 patients (48%), and additional surgery to 20 patients (8%) after completed CCRT. Short-term adverse events (AEs) ≥grade 3 occurred more frequently with NACT-S (41% v 23%), and long-term AEs ≥grade 3 more often with CCRT (21% v 15%). The 5-year OS was not significantly different between NACT-S (72%; 95% CI, 66 to 77) and CCRT (76%; 95% CI, 70 to 80).

CONCLUSION

This trial failed to demonstrate superiority in favor of the NACT-S arm but resulted in acceptable morbidity and HRQOL in both arms.

Surgical Outcomes in Early-Stage Cervical Cancer Following Radical Hysterectomy in a Resource-Limited Setting: The Experience of the National Cancer Institute (Apeksha Hospital, Maharagama), Sri Lanka

Introduction Cervical carcinoma is the commonest gynecological malignancy in Sri Lanka, and this incidence is rising. Radical hysterectomy is the preferred treatment for stages IB1, IB2, and selected cases of stages IIA1. Although surgery is feasible unless the parametrium is involved, careful patient selection is crucial in order to prevent the patient from receiving a dual mode of radical treatment (surgery and radiotherapy). Pre-operative imaging with MRI and PET-CT can accurately determine the tumor size and the lymph node metastasis. In a resource-limited setting, management is challenging as access to MRI and PET-CT is limited. This study was carried out to evaluate the surgical outcomes, five-year survival, and disease-free survival following radical hysterectomies at the National Cancer Institute, Sri Lanka, which performs the largest number of radical hysterectomies annually in the country. Methods Seventy-four patients who underwent radical hysterectomy, along with pelvic lymphadenectomy, between July 2015 to January 2017 at the National Cancer Institute, Sri Lanka (Apeksha Hospital Maharagama), were reviewed retrospectively, analyzing their clinical data and histopathological findings. Univariate analysis was performed to identify associated factors and mean survival. The Kaplan-Meier method was used for survival analysis. Results With a median follow-up of 63.5 months, five-year disease-free survival was 94.5%, and the five-year overall survival was 95.9%. There is a statistically significant association between mean survival and the cell type, presence of LVSI, and residual tumor on the hysterectomy specimen. Only four patients developed recurrences and four patients died during the follow-up. Eighteen (24.3%) patients needed blood transfusion postoperatively and no cases of bladder or bowel dysfunction in the one year post-operatively. Thirty patients (40.5%) required postoperative adjuvant treatment. Conclusions This analysis shows excellent surgical and oncological outcomes following radical hysterectomy as a primary treatment and comparable five-year disease-free survival with available global figures, despite the multiple scarcity of resources. Further studies are needed to assess the national-level status, and limited access to imaging during surgical planning poses a risk for patients receiving dual modes of radical treatment.

Impact of examined lymph node number on lymph node status and prognosis in FIGO stage IB-IIA cervical squamous cell carcinoma: A population-based study

Objective

We aimed to investigate the association of examined lymph node (ELN) number with lymph node status and long-term survival in FIGO stage IB-IIA cervical squamous cell carcinoma(CSCC) and to determine the minimum number of ELN associated with survival improvement.

Method

Data from the Surveillance, Epidemiology, and End Results Program (SEER) database of FIGO stage IB-IIA CSCC patients undergoing hysterectomy and pelvic lymphadenectomy in 2004-2016 were analyzed to explore the relationship between ELN number and lymph node status and overall survival (OS) by using the multivariable approach. The estimated probability of falsely identifying a patient as node-negative and the hazard ratios (HRs) for each ELN was fitted with a LOWESS smoother, and the structural breakpoints were determined. X-tile software was used to determine the optimal cutoff value for ELNs.

Results

A total of 2627 patients were analyzed. The optimal cutoff value of the ELN number was identified as 7 based on the results of X-tile software. The structural breakpoints according to the associations between the number of ELNs and the estimated risk of false-negative lymph node dissection and HRs for overall survival were 9 and 8, respectively. The multivariate analysis indicated that ELN number was an independent prognostic factor for OS, both as a continuous or categorical variable. To further explore the effect of more ELNs on survival, another cutoff value of 17 was chosen to compare the survival curves of patients. The multivariate-adjusted COX model showed that patients with ELN<8 had a significantly higher risk of death than those with ELN8-17 (HR=1.447, 95% CI =1.075-1.947, p=0.015), but there was no significant difference in overall survival between patients with ELN>17 and patients with ELN8-17 (HR=0.822, 95%CI =0.665-1.016, p=0.070).

Conclusion

A sufficient number of ELNs was associated with better long-term survival in FIGO stage IB-IIA CSCC. At least 8 ELNs need to be examined for prognostic stratification. Excessive lymph node dissection (ELN>17) may not confer additional survival benefits.

Robotic single-site versus multiport radical hysterectomy in early stage cervical cancer: An analysis of 62 cases from a single institution

Background

This study aimed to compare the surgical outcomes and cost of robotic single‐site radical hysterectomy (RSSRH) versus robotic multiport radical hysterectomy (RMPRH) with pelvic lymph node dissection in early stage cervical cancer.

Methods

Sixty‐two patients with early stage cervical cancer were recruited between November 2011 and July 2017 and underwent RSSRH (20 patients) and RMPRH (42 patients) for early stage cervical cancer using the da Vinci Si Surgical System (Intuitive Surgical).

Results

There were no significant difference between the two groups in most of parameters. However, postoperative hospital discharge and total hospital costs for RSSRH were significantly shorter than RMPRH (both p < 0.001). However, lymph node retrieval of RMPRH was significantly higher than RSSRH in (18.0 vs. 9.5, respectively; p < 0.001).

Conclusions

RSSRH has comparable surgical outcomes to the RMPRH method. RSSRH could be considered a surgical option in a well‐selected patient group.

2018 FIGO Staging Classification for Cervical Cancer: Added Benefits of Imaging

Cervical cancer is the fourth most common cancer in women of all ages worldwide. The disease is staged using the International Federation of Gynecology and Obstetrics (FIGO) system, which was updated in 2018. The authors explain the key changes from the 2009 version and the rationale behind them. The changes have been made to reflect common clinical practice, differentiate prognostic outcomes, and guide treatment stratification. Treatment options are dependent on the stage of disease and include fertility-sparing and non-fertility-sparing surgical options as well as chemoradiotherapy for locally advanced disease. The updated FIGO staging gives added importance to MRI as a method of accurately measuring tumor size and depicting the presence of parametrial involvement. With the inclusion of lymph node involvement in the updated 2018 FIGO staging, cross-sectional imaging-and in particular, fluorodeoxyglucose PET/CT-has an increasing role in the depiction of nodal disease. Understanding the radiologic techniques used, the literature supporting them, and common imaging pitfalls ensures accurate staging of disease and optimization of treatment. ^©RSNA, 2020 See discussion on this article by Javitt (pp 1823-1824).

Achievement of Surgical Proficiency in Laparoscopic Surgery for Early Endometrial Cancer by Gynecologic Oncologists

OBJECTIVE

Although studies have evaluated learning curves for laparoscopic surgery (LS), this issue has not yet been addressed in gynecologic oncologists. The present study aimed to evaluate LS proficiency for early-stage endometrial cancer among gynecologic oncologists.

METHODS

We examined 25 cases in which LS with pelvic lymphadenectomy (PLA) for endometrial cancer was performed by two gynecologic oncologists undergoing training in LS. The LS duration, estimated blood loss (EBL), number of dissected pelvic lymph nodes (PLNs), and perioperative complications were assessed as measures of surgical proficiency.

RESULTS

Operators A and B performed 10 and 15 cases, respectively, with median LS durations of 348.5 and 378 minutes, respectively. Although the LS duration and number of procedures did not exhibit a significant correlation, the regression lines for both operators showed decreasing trends. Both operators had a consistently low median EBL (A, 57 ml; B, 60 ml). Operators A and B dissected a median of 21.5 and 22 PLNs, respectively. Although both operators dissected a relatively large number of PLNs, with a median of over 20 per patient after the introduction of LS, this number decreased as the number of LS increased for Operator B (p=0.009). However, no correlation was observed between the LS duration and number of PLNs dissected by Operator B (ρ=0.353, p=0.197). A severe perioperative complication, specifically perforation of the sigmoid colon requiring emergent laparotomy, occurred in one case; however, the association with surgical manipulation was not definitive.

CONCLUSION

The observed gynecologic oncologists were able to acquire early proficiency in LS for early-stage endometrial cancer.

Does the extension of the type of hysterectomy contribute to the local control of endometrial cancer?

OBJECTIVE

To examine the necessity and sufficiency of different types of hysterectomy for the surgical treatment of endometrial cancer.

METHODS

This was a multicenter collaborative study conducted by 11 institutions. Among patients with stage I-III endometrial cancer who underwent surgery as the initial treatment (only chemotherapy was provided if adjuvant therapy was needed) from 2001 to 2012, we retrospectively examined the type of hysterectomy, clinicopathological factors, recurrence rate over a maximum period of 5 years, and the site of recurrence. The local recurrence rate was examined by univariate and multivariate analyses.

RESULTS

Among 1335 patients, 982 (73.6%) underwent simple hysterectomy (SH) and 353 (26.4%) underwent modified radical hysterectomy (mRH) and were observed for a mean duration of 51.8 months. No significant difference was observed in the rate of local recurrence between the SH and mRH groups (p = 0.928). In multivariate analysis, clinicopathological factors independently associated with localized recurrence included postmenopausal status [hazard ratio (HR) 5.036, 95% confidence interval (CI) 1.506-16.841, p = 0.009], with stages II (HR 3.337, 95% CI 1.701-6.547, p < 0.001) and III (HR 2.445, 95% CI 1.280-4.668, p = 0.007), vs stage I and histological type 2 (HR 1.610, 95% CI 0.938-2.762, p = 0.001).

CONCLUSIONS

For endometrial cancer patients requiring surgery, the selection of a more extensive type of hysterectomy did not reduce the rate of local recurrence. Therefore, there is little significance in performing mRH in such cases.

Nerve-sparing radical hysterectomy compared to standard radical hysterectomy for women with early stage cervical cancer (stage Ia2 to IIa)

BACKGROUND

Radical hysterectomy is one of the standard treatments for stage Ia2 to IIa cervical cancer. Bladder dysfunction caused by disruption of the pelvic autonomic nerves is a common complication following standard radical hysterectomy and can affect quality of life significantly. Nerve-sparing radical hysterectomy is a modified radical hysterectomy, developed to permit resection of oncologically relevant tissues surrounding the cervical lesion, while preserving the pelvic autonomic nerves.

OBJECTIVES

To evaluate the benefits and harms of nerve-sparing radical hysterectomy in women with stage Ia2 to IIa cervical cancer.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 4), MEDLINE via Ovid (1946 to May week 2, 2018), and Embase via Ovid (1980 to 2018, week 21). We also checked registers of clinical trials, grey literature, reports of conferences, citation lists of included studies, and key textbooks for potentially relevant studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) evaluating the efficacy and safety of nerve-sparing radical hysterectomy compared to standard radical hysterectomy for women with early stage cervical cancer (stage Ia2 to IIa).

DATA COLLECTION AND ANALYSIS

We applied standard Cochrane methodology for data collection and analysis. Two review authors independently selected potentially relevant RCTs, extracted data, evaluated risk of bias of the included studies, compared results and resolved disagreements by discussion or consultation with a third review author, and assessed the certainty of evidence.

MAIN RESULTS

We identified 1332 records as a result of the search (excluding duplicates). Of the 26 studies that potentially met the review criteria, we included four studies involving 205 women; most of the trials had unclear risks of bias. We identified one ongoing trial.The analysis of overall survival was not feasible, as there were no deaths reported among women allocated to standard radical hysterectomy. However, there were two deaths in among women allocated to the nerve-sparing technique. None of the included studies reported rates of intermittent self-catheterisation over one month following surgery. We could not analyse the relative effect of the two surgical techniques on quality of life due to inconsistent data reported. Nerve-sparing radical hysterectomy reduced postoperative bladder dysfunctions in terms of a shorter time to postvoid residual volume of urine ≤ 50 mL (mean difference (MD) -13.21 days; 95% confidence interval (CI) -24.02 to -2.41; 111 women; 2 studies; low-certainty evidence) and lower volume of postvoid residual urine measured one month following operation (MD -9.59 days; 95% CI -16.28 to -2.90; 58 women; 2 study; low-certainty evidence). There were no clear differences in terms of perioperative complications (RR 0.55; 95% CI 0.24 to 1.26; 180 women; 3 studies; low-certainty evidence) and disease-free survival (HR 0.63; 95% CI 0.00 to 106.95; 86 women; one study; very low-certainty evidence) between the comparison groups.

AUTHORS' CONCLUSIONS

Nerve-sparing radical hysterectomy may lessen the risk of postoperative bladder dysfunction compared to the standard technique, but the certainty of this evidence is low. The very low-certainty evidence for disease-free survival and lack of information for overall survival indicate that the oncological safety of nerve-sparing radical hysterectomy for women with early stage cervical cancer remains unclear. Further large, high-quality RCTs are required to determine, if clinically meaningful differences of survival exist between these two surgical treatments.

Laparoscopic repair of the vaginal cuff dehiscence: Dehiscence occurring after the first sexual intercourse after the laparoscopic modified radical hysterectomy

Total vaginal cuff dehiscence (VCD) is an important adverse event after hysterectomy. Here, we showed two cases in whom laparoscopic repair of VCD was successful. This procedure is effective, safe, and thus minimally invasive for patients after hysterectomy.

Type II or type III radical hysterectomy compared to chemoradiotherapy as a primary intervention for stage IB2 cervical cancer

BACKGROUND

Cervical cancer is the fourth most common cancer in women, with 528,000 estimated new cases globally in 2012. A large majority (around 85%) of the disease burden occurs in low- and middle-income countries (LMICs), where it accounts for almost 12% of all female cancers. Treatment of stage IB2 cervical cancers, which sit between early and advanced disease, is controversial. Some centres prefer to treat these cancers by radical hysterectomy, with chemoradiotherapy reserved for those at high risk of recurrence. In the UK, we treat stage IB2 cervical cancers mainly with chemoradiotherapy, based on the rationale that a high percentage will have risk factors necessitating chemoradiotherapy postsurgery. There has been no systematic review to determine the best possible evidence in managing these cancers.

OBJECTIVES

To determine if primary surgery for stage IB2 cervical cancer (type II or type III radical hysterectomy with lymphadenectomy) improves survival compared to primary chemoradiotherapy.To determine if primary surgery combined with postoperative adjuvant chemoradiotherapy, for stage IB2 cervical cancer increases patient morbidity in the management of stage IB2 cervical cancer compared to primary chemoradiotherapy.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 3), MEDLINE via Ovid (1946 to April week 2, 2018) and Embase via Ovid (1980 to 2018 week 16). We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of included studies up to April 2018.

SELECTION CRITERIA

We searched for randomised controlled trials (RCTs), quasi-RCTs or non-randomised studies (NRSs) comparing surgery to chemoradiotherapy in stage IB2 cervical cancers.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed whether potentially relevant studies met the inclusion criteria, abstracted data, assessed risk of bias and analysed data using standard methodological procedures expected by Cochrane.

MAIN RESULTS

We identified 4968 records from the literature searches, but we did not identify any RCTs that compared primary surgery with chemoradiotherapy in stage IB2 cervical cancer.We found one NRS comparing surgery to chemoradiotherapy in IB2 and IIA2 cervical cancers which met the inclusion criteria. However, we were unable to obtain data for stage IB2 cancers only and considered the findings very uncertain due to a high risk of selection bias.

AUTHORS' CONCLUSIONS

There is an absence of high-certainty evidence on the relative benefits and harms of primary radical hysterectomy versus primary chemoradiotherapy for stage IB2 cervical cancer. More research is needed on the different treatment options in stage IB2 cervical cancer, particularly with respect to survival, adverse effects, and quality of life to facilitate informed decision-making and individualised care.

Is aortic lymphadenectomy indicated in locally advanced cervical cancer after neoadjuvant chemotherapy followed by radical surgery? A retrospective study on 261 women

OBJECTIVES

The aim of this study was to estimate the rate of aortic lymph nodes (LN) metastases/recurrences among patients affected by locally advanced stage cancer patients (LACC), treated with neoadjuvant chemotherapy (NACT) and radical surgery.

METHODS

Retrospective evaluation of consecutive 261 patients affected by LACC (stage IB2-IIB), treated with NACT followed by radical surgery at National Cancer Institute, Milan, Italy, between 1990 and 2011.

RESULTS

Stage at presentation included stage IB2, IIA and IIB in 100 (38.3%), 50 (19.2%) and 111 (42.5%) patients, respectively. Squamous cell carcinoma accounted for more than 80%, followed by adenocarcinoma or adenosquamous cancers (20%). Overall, 56 women (21.5%) had LN metastases. Four out of 83 women (5%) who underwent both pelvic and aortic LN dissection had aortic LN metastases, and all women had concomitant pelvic and aortic LN metastases. Only one woman out of 178 (0.5%) who underwent pelvic lymphadenectomy only, had an aortic LN recurrence. Overall 2% of women (5/261) had aortic LN metastases/recurrence.

CONCLUSIONS

Our data suggest that aortic lymphadenectomy at the time of surgery is not routinely indicated in LACC after NACT, but should reserved in case of bulky LN in both pelvic and/or aortic area. The risk of isolated aortic LN relapse is negligible. Further prospective studies are warranted.

Quality of life, urogynecological morbidity, and lymphedema after radical vaginal trachelectomy for early-stage cervical cancer

OBJECTIVE

Radical vaginal trachelectomy (RVT) offers a possibility for future childbearing for young women with early-stage cervical cancer. However, the literature on quality of life and self-reported morbidity in patients undergoing RVT is scarce. The aim of this study was to prospectively assess quality of life after RVT with focus on urogynecological morbidity and lymphedema. Furthermore, the aim of this study was to compare results with those in women treated with radical abdominal hysterectomy (RAH) and with age-matched control women from the general population.

METHODS AND MATERIALS

Eighteen patients with early-stage cervical cancer operated with RVT were prospectively included and assessed preoperatively, 3, 6, and 12 months postoperatively using validated questionnaires. Thirty-two patients treated with RAH were included consecutively and assessed once at 12 months postsurgery, whereas an age-matched control group of 30 healthy women was assessed once.

RESULTS

Fifty percent of the RVT group and 41% of the RAH reported any grade of incomplete bladder emptying problems at 1 year postsurgery assessment. Eleven percent of the RVT patients and 12.5% of the RAH patients reported severe lymphedema of the legs as assessed by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Cervical Cancer Module. The Global Health Status scores of the RVT patients improved over time but were significantly lower than in the healthy controls during the entire observation time (P = 0.029).

CONCLUSIONS

Patients treated with RVT for early-stage cervical cancer had persistent bladder emptying problems and lymphedema comparable to those experienced by patients treated with RAH and significantly higher than those reported by healthy control women.

Predictors of complications in gynaecological oncological surgery: a prospective multicentre study (UKGOSOC-UK gynaecological oncology surgical outcomes and complications)

BACKGROUND

There are limited data on surgical outcomes in gynaecological oncology. We report on predictors of complications in a multicentre prospective study.

METHODS

Data on surgical procedures and resulting complications were contemporaneously recorded on consented patients in 10 participating UK gynaecological cancer centres. Patients were sent follow-up letters to capture any further complications. Post-operative (Post-op) complications were graded (I-V) in increasing severity using the Clavien-Dindo system. Grade I complications were excluded from the analysis. Univariable and multivariable regression was used to identify predictors of complications using all surgery for intra-operative (Intra-op) and only those with both hospital and patient-reported data for Post-op complications.

RESULTS

Prospective data were available on 2948 major operations undertaken between April 2010 and February 2012. Median age was 62 years, with 35% obese and 20.4% ASA grade ⩾3. Consultant gynaecological oncologists performed 74.3% of operations. Intra-op complications were reported in 139 of 2948 and Grade II-V Post-op complications in 379 of 1462 surgeries. The predictors of risk were different for Intra-op and Post-op complications. For Intra-op complications, previous abdominal surgery, metabolic/endocrine disorders (excluding diabetes), surgical complexity and final diagnosis were significant in univariable and multivariable regression (P<0.05), with diabetes only in multivariable regression (P=0.006). For Post-op complications, age, comorbidity status, diabetes, surgical approach, duration of surgery, and final diagnosis were significant in both univariable and multivariable regression (P<0.05).

CONCLUSIONS

This multicentre prospective audit benchmarks the considerable morbidity associated with gynaecological oncology surgery. There are significant patient and surgical factors that influence this risk.

Nerve-Sparing Versus Conventional Laparoscopic Radical Hysterectomy: A Minimum 12 Months’ Follow-up Study

Objective

The objective of this study was to determinate whether the introduction of nerve-sparing (NS) procedure influences surgical and survival outcomes of cervical cancer patients undergoing laparoscopic radical hysterectomy (LRH).

Methods

Data of consecutive patients undergoing minimally invasive radical with or without NS surgery for cervical cancer were enrolled in the study.

Results

Sixty-three patients (66%) who had LRH were compared with 33 women (34%) undergoing NS-LRH. Among the NS group, 19 patients (57.6%) had surgery via minilaparoscopy (using 3-mm instruments). Baseline characteristics were similar between groups. Patients undergoing NS-LRH had shorter operative time (210 vs 257 minutes; P = 0.005) and higher number of pelvic lymph nodes yielded (29 [26–38] vs 22 [8–49]; P < 0.001) than patient in the control group. No differences in blood loss, complications, and parametrial width were observed. Patients were catheterized with an indwelling Foley catheter for a median of 3.5 days (2–7 days) and 5.5 days (4–7 days) in NS and non-NS groups, respectively (P = 0.01). Voiding dysfunctions occurred in 1 patient (3%) and 12 patients (19%) who underwent NS-LRH and standard LRH, respectively (P = 0.03). No differences in 3-year disease-free survival (P = 0.72) and overall survival (P = 0.71) were recorded.

Conclusions

The beneficial effects (in terms of operative time and number of nodes harvested) of NS-LRH are likely determined by the expertise of the surgeon because NS approach was introduced after having acquired adequate background in conventional LRH. Our data show that in experienced hands NS-LRH is safe and feasible. Moreover, NS technique reduces catheterization time and the rate of postoperative urinary dysfunction.

Laparoscopic versus open abdominal management of cervical cancer: long-term results from a propensity-matched analysis

STUDY OBJECTIVE

To compare perioperative and long-term outcomes related to laparoscopic and open abdominal surgical management of cervical cancer.

DESIGN

Propensity-matched comparison of prospectively collected data (Canadian Task Force classification II-1).

SETTING

University teaching hospital.

PATIENTS

Sixty-five propensity-matched patient pairs (130 patients) undergoing either laparoscopy or open abdominal surgical procedures to treat cervical cancer.

INTERVENTION

Radical hysterectomy plus lymphadenectomy was performed via the laparoscopic (LRH) or open abdominal approach (RAH).

MEASUREMENT AND MAIN RESULTS

Baseline characteristics of the study populations were similar. In the LRH group the procedure was converted to open surgery in 2 patients (2%). Compared with the RAH group, patients undergoing LRH experienced less blood loss (200 vs 500 mL; p < .001), a lower transfusion rate (6% vs 22%; p = .02), similar operative time (245 vs 259.5 minutes; p = .26), and shorter length of hospital stay (4 vs 8 days; p < .001). No between-group differences in intraoperative complications were recorded (p = 1.0); however, a trend toward a lower postoperative complication rate (Accordion system grade ≥ 3) was observed for LRH compared with RAH (4 patients [6%]) vs 12 patients [18%]; p = .06). Five-year disease-free survival (p = .6, log-rank test) and overall survival (p = .31, log-rank test) did not differ statistically between women undergoing LRH or RAH.

CONCLUSION

Laparoscopy ensures the same results as open surgery insofar as radicality and long-term survival. Use of the laparoscopic approach is associated with improved short-term results, minimizing the occurrence of severe postoperative complications.

Urological complications after treatment of cervical cancer

Several urological complications can occur after treatment of cervical cancer. Stage IB and IIA cervical tumours are mainly treated by radical hysterectomy; advanced-stage tumours are treated by chemoradiotherapy. In the past two decades, a decrease in complications has been seen due to improvements in therapy, although the exact incidence of lower urinary tract dysfunction is unknown. The main urological complications after radical surgery are hypocontractility of the bladder, detrusor overactivity, incontinence, low-compliance bladder, fistula and hydronephrosis. As a result of improved neuroanatomical knowledge, and consequently nerve-sparing surgery, bladder morbidity has been decreasing. Late radiation-induced urological complications include haemorrhagic cystitis, ureteric stenosis, low-compliance bladder and fistulas. Owing to technological improvements, such as dose reduction and decreased radiation fields, a decrease in radiation morbidity has been observed since 1990.

Effect of nerve-sparing radical hysterectomy on bladder function recovery and quality of life in patients with cervical carcinoma

OBJECTIVE

To investigate the bladder function recovery and quality of life (QOL) using nerve-sparing radical hysterectomy (NSRH) in treating early invasive cervical carcinoma.

METHODS

Subjects included patients who underwent radical hysterectomy by laparotomy for early-stage cervical carcinoma. Thirty-one patients were randomly assigned to 2 groups: group A, 15 patients who underwent NSRH; and group B, 16 patients who underwent classical radical hysterectomy. We observed the patients' general clinical information, surgical characteristics, postoperative vital signs, pathological findings, adjuvant therapies, and adverse effects. A urodynamic study was used to assess the bladder function. The patients' QOL was evaluated by Functional Assessment of Cervical Cancer Therapy (FACT-Cx).

RESULTS

Twenty-nine patients completed the study. No significant differences were found in age, body mass index, surgery characteristics, pathological findings, adjuvant therapies, and main adverse effects between the 2 groups (P > 0.05). The postoperative time of bladder function recovery in group A was obviously earlier than that in group B (P < 0.05). The urodynamic study showed that the extent of bladder function recovery in group A was better than that in group B (P < 0.05). The QOL in group A evaluated 1 year after operation was improved compared with that in group B (P < 0.05). The QOL analysis showed that group A did much better than group B in social and family life, emotional well-being, working status, and the symptom correlated with the operation (P < 0.05). No significant differences were found in basic bodily functions (P > 0.05).

CONCLUSIONS

Nerve-sparing radical hysterectomy is a safe and reliable technique for early invasive cervical carcinoma. The postoperative bladder function recovery and the patients' QOL were improved after NSRH compared with the control group. Therefore, NSRH could be an alternative management to modify the classical surgery for cervical carcinoma with International Federation of Gynecology and Obstetrics stages IB1 to IIA.
