Comparison of 3D and 2D laparoscopy: Initial experience of perioperative outcomes and clinical assessment.

INTRODUCTION: This study was designed to compare three-dimensional (3D) laparoscopy and conventional two-dimensional (2D) laparoscopy in surgical performance and clinical assessment during laparoscopic radical hysterectomy with pelvic lymphadenectomy (LRHND) for treating early-stage cervical cancer. MATERIAL AND METHODS: In this study, we included 67 consecutive patients underwent LRHND for treating early-stage cervical cancer by the experienced laparoscopic surgeons between August 2018 and December 2020. amongst these patients, 32 patients underwent 3D laparoscopy (2D group) and 35 patients underwent 2D laparoscopy (2D group). Demographic data, clinical and surgical parameters were obtained from each patient. An end-of-operation questionnaire was administered regarding subjective perception of 3D laparoscopy system. RESULTS: Patient characteristics, including age, BMI, FIGO stage, and histology, were comparable between the two groups. Compared with 2D imaging system, 3D system significantly shortened the operation time, especially bilateral lymph node dissection time. Blood loss was lower in 3D group compared with 2D group. There were no significant differences regarding pelvic nodes retrieved, incidence of complications, hospital stay, the recovery time of bowel, abdominal drainage fluid, hospitalization costs and visual symptoms. In addition, 3D system significantly improved depth perception and precision, and reduced surgical strain and eye strain for surgeon. No statistical difference was observed in visual symptoms and adverse events between the two groups. The surgeon was more willing to accept 3D laparoscopy. CONCLUSION: The 3D laparoscopy is safe, feasible and comfortable, with obvious advantage in depth perception, precision and surgical strain. It triggered no increase in the complications and adverse events.

Evaluating equity of access and predictors of minimally invasive hysterectomy for endometrial and cervical cancer from 2000 to 2017 in Ontario, Canada: A population-based cohort study.

INTRODUCTION: We sought to assess the uptake of minimally invasive hysterectomy among patients with endometrial and cervical cancer in Ontario, Canada, and assess the equity of access to minimally invasive surgery (MIS) by evaluating associations with patient, disease, institutional, and provider factors. METHODS: This is a retrospective population-based cohort study of hysterectomy for endometrial and cervical cancer in Ontario (2000-2017). Surgical approach, clinicopathologic, sociodemographic, institutional, and provider factors were identified through administrative databases. Fisher's exact, χ2 , Wilcoxon rank sum, logistic regression, and Cox proportional hazards modeling were used to explore factors associated with MIS. RESULTS: A total of 27 652 patients were included. In total, 6199/24 264 (26%) endometrial and 842/3388 (25%) cervical cancer patients received MIS. The proportion of MIS to open surgeries increased from <0.1% in 2000 to over 55% in 2017 (odds ratio [OR] = 1.31, confidence interval [CI] = 1.28-1.34). Low-income quintile, rurality, low hospital volume, nonacademic hospital, nongynecologic oncology surgeon, and earlier year of surgeon graduation were associated with reduced odds of MIS (OR < 1). CONCLUSIONS: The uptake of MIS hysterectomy increased steadily over the time period. Receipt of MIS is dependent upon multiple social determinants, provider variables, and systems factors. These disparities raise concern for health equity in Ontario and have significant implications for health systems planning and resource allocation.

Survival differences by race and surgical approach in early-stage operable cervical Cancer.

OBJECTIVE: To evaluate if the higher rate of open radical hysterectomy in Black patients, prior to the widespread return to open surgical techniques, mitigated survival disparities and to identify other actionable factors to target for systemic change. METHODS: This is a retrospective cohort study including patients from the National Cancer Database with cervical cancer who underwent radical hysterectomy from 2010 to 2018. Patient demographics, clinical characteristics and survival were compared by race and surgical route. Kaplan-Meier plots were constructed. Cox proportional hazards modeling was used to adjust for covariates. RESULTS: 7201 patients were eligible for inclusion, 687 (9.5%) Black and 4870 (68%) White. We found that 51% of Black patients and 39% of White patients underwent open surgery. Black patients were 10% less likely to receive Guideline Concordant Care (GCC). Those with publicly-funded insurance had a 40% higher hazard of death compared to private insurance (CI 1.19-1.73 p < 0.001). Black patients who had open surgery had similar 5-year survival compared to White patients who had MIS surgery (0.90 vs 0.91, NS). After adjusting for potential confounders including age, insurance, nodal status, and lymphovascular space invasion, Black patients who had surgery had a 40% higher hazard for death (HR 1.40 95% CI 1.10-1.79, p = 0.007) compared to White patients. CONCLUSIONS: A lower 5 and 10-year survival was seen in Black patients, regardless of surgical approach. Adjustment for significant covariates did not resolve this disparity, confirming that these factors do not fully account racial disparities.

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.

Adjuvant Human Papillomavirus Vaccination After Excisional Procedure for Cervical Intraepithelial Neoplasia: A Cost-Effectiveness Analysis.

OBJECTIVE: To examine the cost effectiveness of human papillomavirus (HPV) vaccination after excisional procedure compared with no vaccination. METHODS: We constructed a decision-analytic model (TreeAge Pro 2021) to compare outcomes between patients who underwent an excisional procedure followed by nonavalent HPV vaccination to those who underwent an excisional procedure without vaccination. Our theoretical cohort contained 250,000 patients, the approximate number undergoing excisional procedures annually in the United States. Our outcomes were costs, quality-adjusted life-years (QALYs), recurrence events, number of surveillance Pap tests with co-testing, number of colposcopies, and second excisional procedures. Probabilities of recurrence were based on a recently published meta-analysis. All values were derived from the literature, and QALYs were discounted at a rate of 3%. Outcomes were applied for 4 years after the initial excisional procedure. Our cost-effectiveness threshold was $100,000 per QALY. Sensitivity analyses were performed to evaluate the robustness of the model. RESULTS: In our theoretical cohort of patients who underwent an excisional procedure, the HPV vaccination strategy was associated with 17,281 fewer recurrences of cervical intraepithelial neoplasia (CIN) (8,360 fewer cases of CIN 1 and 8,921 fewer cases of CIN 2 or 3), 26,203 fewer Pap tests (1,025,368 vs 1,051,570), 17,281 fewer colposcopies (20,588 vs 37,869), and 8,921 fewer second excisional procedures (4,779 vs 13,701). The vaccination strategy was associated with a higher cost of $135 million. Vaccination was a cost-effective strategy, with an incremental cost-effectiveness ratio of $29,181 per QALY, compared with no vaccination. In our sensitivity analyses, the HPV vaccination strategy remained cost effective until the cost of the three-dose HPV vaccine series reached $1,899 or the baseline (nonvaccinated) probability of recurrence was less than 4.8%. CONCLUSION: In our model, HPV vaccination for patients with a prior excisional procedure led to improved outcomes and was cost effective. Our study suggests that clinicians should consider offering the three-dose HPV vaccine series to patients who have undergone an excisional procedure to decrease the risk of CIN recurrence and its sequelae.

A Multicenter Study on Preoperative Assessment of Lymphovascular Space Invasion in Early-Stage Cervical Cancer Based on Multimodal MR Radiomics.

BACKGROUND: As lymphovascular space invasion (LVSI) was closely related to lymph node metastasis and prognosis, the preoperative assessment of LVSI in early-stage cervical cancer is crucial for patients. PURPOSE: To develop and validate nomogram based on multimodal MR radiomics to assess LVSI status in cervical cancer patients. STUDY TYPE: Retrospective. POPULATION: The study included 168 cervical cancer patients, of whom 129 cases (age 51.36 ± 9.99 years) from institution 1 were included as the training cohort and 39 cases (age 52.59 ± 10.23 years) from institution 2 were included as the external test cohort. FIELD STRENGTH/SEQUENCE: There were 1.5 T and 3.0 T MRI scans (T1-weighted imaging [T1WI], fat-saturated T2-weighted imaging [FS-T2WI], and contrast-enhanced [CE]). ASSESSMENT: Six machine learning models were built and selected to construct the radiomics signature. The nomogram model was constructed by combining the radiomics signature with the clinical signature, which was then validated for discrimination, calibration, and clinical usefulness. STATISTICAL TESTS: The clinical characteristics were compared using t-tests, Mann-Whitney U tests, or chi-square tests. The Spearman and LASSO methods were used to select radiomics features. The receiver operating characteristic (ROC) analysis was performed, and the area under the curve (AUC), accuracy, sensitivity, and specificity were calculated. RESULTS: The logistic regression (LR) model performed best in each sequence. The AUC of CE-T1-T2WI-combined was the highest in the LR model, with an AUC of 0.775 (95% CI: 0.570-0.979) in external test cohort. The nomogram showed high predictive performance in the training (AUC: 0.883 [95% CI: 0.823-0.943]) and test cohort (AUC: 0.830 [95% CI: 0.657-1.000]) for predicting LVSI. Decision curve analysis demonstrated that the nomogram was clinically useful. DATA CONCLUSION: Our findings suggest that the proposed nomogram model based on multimodal MRI of CE T1WI-T2WI-combined could be used to assess LVSI status in early cervical cancer. EVIDENCE LEVEL: 4. TECHNICAL EFFICACY: Stage 2.

Transformation Zone Assessment Using Visual Inspection With Acetic Acid Before and After Thermal Ablation: Implications for Follow-Up.

PURPOSE: Thermal ablation (TA) has become the conventional method for treatment of precancerous cervical lesions in low-resource settings. After TA, both the squamocolumnar junction (SCJ) and the transformation zone (TZ) may be subject to change. Our aim was to evaluate SCJ and TZ variability after TA. METHODS: Study data were collected in a large prospective trial of a cervical cancer screening campaign in Cameroon. For each patient, two sets of cervical photos (native and with acetic acid) were taken before and 6-12 months after TA. The SCJ and TZ were evaluated independently by three observers according to the WHO nomenclature. When discordances were observed between the type of TZ and SCJ selected by each observer, a corrected TZ was established on the basis of the SCJ categorization. Interobserver agreement for TZ interpretation was evaluated using Cohen's kappa coefficient for agreement between two observers and Fleiss' kappa between three observers. RESULTS: Fifty consecutive participants were included in the analysis. Seventy-six percent were interpreted as TZ1-2, and 24% as TZ3 before TA. In 56% of cases, the entire SCJ could not be entirely visualized after TA, thus being recategorized as TZ3. Interobserver agreement was fair for diagnosis before TA (Kappa coefficient, 0.34; 95% CI, 0.27 to 0.45) and moderate for diagnosis after TA (Kappa coefficient, 0.40; 95% CI, 0.30 to 0.50). After TA, 36% progressed from TZ1-2 to TZ3, with a moderate interobserver agreement (Kappa coefficient, 0.44; 95% CI, 0.40 to 0.54). CONCLUSION: We observed a shift of the SCJ into the endocervical canal after TA. A significant proportion of participants had TZ 3 after treatment, raising the question of visual inspection with acetic acid's applicability as a first-line follow-up examination method after TA.

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.

Long-term quality of life assessment after excisional treatment for cervical dysplasia.

We evaluated factors influencing long-term health-related quality of life (HRQoL) after excisional treatments of low- and high grade squamous intraepithelial cervical lesions (SIL) in three groups of women (n = 160): nulliparas interested in reproduction (A), parous women interested in reproduction (B) and women without pregnancy desire (C). The HRQoL was assessed using the disease-specific FACIT-CD and the generic SF36v2 questionnaires. Anxiety and depression were evaluated by Beck's inventories. After median follow-up of 5 (2-18) years, FACIT-CD total score and the score for Emotional Well-Being (EWB) were significantly lower in group A. The total, EWB and REL (Relationships) scores of FACIT-CD were the highest in group B. Women operated for HSIL demonstrated lower REL quality in comparison to those with LSIL. Neither SF36v2 nor FACIT-CD total scores differed in relation to SIL grade or type of excision. 'SF36v2 Mental Component Summary Score' and 'being parous and interested in fertility' were independent predictors of disease-specific FACIT-CD score.Impact StatementWhat is already known on this subject? Long-term consequences of excisional treatments for cervical dysplasia on health-related quality of life (HRQoL) are not well reported.What do the results of this study add? Our study provides data on HRQoL in women treated with large loop excision of the transformation zone (LLETZ) or cold knife conization (CKC) obtained during the longest (median 5 years) follow-up as reported to date. We were able to show that having children and planning further pregnancies positively influenced HRQoL in these patients. In addition, we identified nulliparas with pregnancy desire as psychologically the most vulnerable group within the studied cohort.What are the implications of these findings for clinical practice and/or further research? Even several years after LLETZ or CKC, women may suffer from impaired Emotional Well-Being and reduced HRQoL. Awareness and assessment of these long-term consequences should be part of surveillance after excisional treatments for cervical dysplasia.

Burden of CIN2+ diagnoses and conizations in women aged 18-45 years-a retrospective secondary data analysis of German statutory health insurance claims data.

PURPOSE: High grade cervical intraepithelial neoplasia (CIN2+) may progress to cervical cancer. They may be detected by screening and are usually treated by conization. This study aimed at assessing annual proportions of screening, prevalent and incident CIN2+ diagnoses, as well as proportions of (re-)conizations during 24 months follow-up after conization in Germany. METHODS: A descriptive retrospective claims data analysis of the years 2013-2018 was conducted using the InGef Research Database. Women aged 18-45 years with CIN2+ diagnoses were identified by ICD-10-GM codes (N87.1, N87.2, D06.-, and C53.-). Cervical conizations were identified by OPS codes (5-671.0* or 5-671.1*). Screening participation was identified by EBM codes (01730, 01733, 32819 or 32820). Annual proportions were calculated as women with the respective documented codes divided by all women in the respective age group per calendar year. RESULTS: Overall annual proportions of screened women spanned from 60.01 to 61.33% between 2013 and 2018. The overall annual prevalence of CIN2+ diagnoses (regardless of screening participation) ranged from 0.72 to 0.84% between 2013 and 2018, with highest proportions observed in women aged 27-45 years. Also, CIN2+ incidence was highest in women 27-45 years. Annual proportion of women undergoing conization was 0.24% in 2013 and 0.21% in 2018. During a 24-month follow-up period after conization, 2.91% of women underwent a re-conization 3 months or later after the initial conization. CONCLUSION: This analysis demonstrates a considerable burden of CIN2+, conizations and re-conizations in Germany, especially in women aged 27-45 years. This highlights the need for intensified prevention efforts such as expanding human papillomavirus (HPV) vaccination.

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

BACKGROUND: Minimally invasive radical trachelectomy has emerged as an alternative to open radical hysterectomy for patients with early-stage cervical cancer desiring future fertility. Recent data suggest worse oncologic outcomes after minimally invasive radical hysterectomy than after open radical hysterectomy in stage I cervical cancer. OBJECTIVE: We aimed to compare 4.5-year disease-free survival after open vs minimally invasive radical trachelectomy. STUDY DESIGN: This was a collaborative, international retrospective study (International Radical Trachelectomy Assessment Study) of patients treated during 2005-2017 at 18 centers in 12 countries. Eligible patients had squamous carcinoma, adenocarcinoma, or adenosquamous carcinoma; had a preoperative tumor size of ≤2 cm; and underwent open or minimally invasive (robotic or laparoscopic) radical trachelectomy with nodal assessment (pelvic lymphadenectomy and/or sentinel lymph node biopsy). The exclusion criteria included neoadjuvant chemotherapy or preoperative pelvic radiotherapy, previous lymphadenectomy or pelvic retroperitoneal surgery, pregnancy, stage IA1 disease with lymphovascular space invasion, aborted trachelectomy (conversion to radical hysterectomy), or vaginal approach. Surgical approach, indication, and adjuvant therapy regimen were at the discretion of the treating institution. A total of 715 patients were entered into the study database. However, 69 patients were excluded, leaving 646 in the analysis. Endpoints were the 4.5-year disease-free survival rate (primary), 4.5-year overall survival rate (secondary), and recurrence rate (secondary). Kaplan-Meier methods were used to estimate disease-free survival and overall survival. A post hoc weighted analysis was performed, comparing the recurrence rates between surgical approaches, with open surgery being considered as standard and minimally invasive surgery as experimental. RESULTS: Of 646 patients, 358 underwent open surgery, and 288 underwent minimally invasive surgery. The median (range) patient age was 32 (20-42) years for open surgery vs 31 (18-45) years for minimally invasive surgery (P=.11). Median (range) pathologic tumor size was 15 (0-31) mm for open surgery and 12 (0.8-40) mm for minimally invasive surgery (P=.33). The rates of pelvic nodal involvement were 5.3% (19 of 358 patients) for open surgery and 4.9% (14 of 288 patients) for minimally invasive surgery (P=.81). Median (range) follow-up time was 5.5 (0.20-16.70) years for open surgery and 3.1 years (0.02-11.10) years for minimally invasive surgery (P<.001). At 4.5 years, 17 of 358 patients (4.7%) with open surgery and 18 of 288 patients (6.2%) with minimally invasive surgery had recurrence (P=.40). The 4.5-year disease-free survival rates were 94.3% (95% confidence interval, 91.6-97.0) for open surgery and 91.5% (95% confidence interval, 87.6-95.6) for minimally invasive surgery (log-rank P=.37). Post hoc propensity score analysis of recurrence risk showed no difference between surgical approaches (P=.42). At 4.5 years, there were 6 disease-related deaths (open surgery, 3; minimally invasive surgery, 3) (log-rank P=.49). The 4.5-year overall survival rates were 99.2% (95% confidence interval, 97.6-99.7) for open surgery and 99.0% (95% confidence interval, 79.0-99.8) for minimally invasive surgery. CONCLUSION: The 4.5-year disease-free survival rates did not differ between open radical trachelectomy and minimally invasive radical trachelectomy. However, recurrence rates in each group were low. Ongoing prospective studies of conservative management of early-stage cervical cancer may help guide future management.

Metal stent for the ureteral stricture after surgery and/or radiation treatment for malignancy.

BACKGROUND: To assess the efficacy and safety of self-expanding metal ureteral stent for the stricture following surgery and/or radiation for malignancy. METHODS: We performed 36 metal ureteral stent insertion procedures (32 patients) between May 2019 and June 2020. The main inclusion criterion was the patients with ureteral stricture due to surgery and/or radiation treatment for malignancy. The diagnosis of stricture was ascertained by history and radiographic imaging. The etiologies underlying the strictures were: surgery and/or radiation therapy for cervical and rectal cancer, surgery for ovarian cancer. The primary outcome was the stent patency rate, and the secondary outcomes were the postoperative complications and glomerular filtration rate (GFR). Stent patency was defined as stent in situ without evident migration, unanticipated stent exchange or recurrent ureteral obstruction. Cost analysis was calculated from stent cost, anesthesia cost and operating room fee. RESULTS: The pre-metallic stent GFR was 22.53 ± 6.55 mL/min/1.73 m2. Eight patients were on double-J stents before insertion of metallic stents. The total annual cost of per patient in our study was $10,600.2 US dollars (range $9394.4-$33,527.4 US dollars). During a median follow-up time of 16 months (range 8-21 months), 27 cases (31 sides, 84%) remained stent patency. Twelve patients died from their primary malignancy carrying a patency stent. Stent migration was observed in 4 patients within 10 months after insertion. Ectopic stents were endoscopically removed and replaced successfully. Three stents were occluded, and no encrustation was seen in our study. Three and four patients had postoperative fever and gross hematuria, respectively. Infection was observed in 2 cases, mandating antibiotics therapy. In addition, postoperative volume of hydronephrosis postoperatively was significantly reduced compared with preoperation (54.18 ± 15.42 vs 23.92 ± 8.3, P = 0.019). However, no statistically significant differences regarding GFR, creatinine levels, blood urea nitrogen and hemoglobin existed between preoperation and last follow-up. CONCLUSIONS: The current study demonstrated that metal ureteral stent is effective and safe in the treatment of stricture following surgery and/or radiation therapy for malignant cancer. Patients hydronephrosis could be improved by the stent placement.

Assessment of Pelvic Floor Function and Quality of Life in Patients Treated for Cervical Cancer: A Multicenter Retrospective Study.

OBJECTIVES: Our study aimed to evaluate the quality of life (QoL) and pelvic floor function of cervical cancer (CC) patients after treatment. DESIGN: This was a cross-sectional observational cohort study. PARTICIPANTS: The participants included in this study were CC patients who underwent radical hysterectomy (RH) from 2012 to 2018 at 18 medical centers across China. METHODS: The validated versions of the Pelvic floor Distress Inventory-Short Form 20, Overactive Bladder Symptom Score, and Euro Qol Five-Dimension questionnaires were used to evaluate postoperative pelvic floor dysfunction (PFD) and QoL. RESULTS: A total of 689 CC patients were enrolled. The incidence of stress urinary incontinence (SUI), incomplete urinary emptying, and constipation were 32.7, 27.7, and 28.6%, respectively. Multivariate analysis confirmed that laparoscopic RH (LRH) and vaginal wall resection greater than 3 cm were risk factors for lower urinary tract symptoms (LUTS). LRH and chemotherapy were risk factors for SUI. Chemoradiotherapy and LRH were risk factors for overactive bladder (OAB). A high body mass index and LRH were risk factors for more severe defecation symptoms. ARH and large amount of operative blood loss were risk factors for poor QoL. CONCLUSION: PFD is common in CC patients after treatment. LRH seems to increase the postoperative distress, including LUTS and defecation symptoms. Postoperative urinary incontinence and OAB are more bothersome for patients undergoing chemotherapy and radiotherapy. We recommend evaluating pelvic floor function as a standard assessment during follow-up.

Cervical conization and lymph node assessment for early stage low-risk cervical cancer.

OBJECTIVE: There has been a contemporary shift in clinical practice towards tailoring treatment in patients with early cervical cancer and low-risk features to non-radical surgery. The objective of this study was to evaluate the oncologic, fertility, and obstetric outcomes after cervical conization and sentinel lymph node (SLN) biopsy in patients with early stage low-risk cervical cancer. METHODS: We conducted a retrospective review in patients with early cervical cancer treated with cervical conization and lymph node assessment between November 2008 and February 2020. Eligibility criteria included patients with a histologic diagnosis of invasive squamous cell carcinoma, adenocarcinoma or adenosquamous carcinoma, International Federation of Gynecology and Obstetrics 2009 stage IA1 with positive lymphovascular space invasion (LVSI), stage IA2, or stage IB1 (≤2 cm) with less than two-thirds (<10 mm) cervical stromal invasion. RESULTS: A total of 44 patients were included in the analysis. The median age was 31 years (range 19-61) and 20 patients (45%) were nulliparous. One patient had a 25 mm tumor while the remaining patients had tumors smaller than 20 mm. Eighteen (41%) patients had LVSI. Median follow-up was 44 months (range 6-137). A total of 17 (39%) patients had negative margins on the diagnostic excisional procedure, and none had residual disease on the repeat cone biopsy. Three (6.8%) patients had micrometastases detected in the SLNs and underwent ipsilateral lymphadenectomy; all remaining non-SLN lymph nodes were negative. Six (13.6%) patients required more definitive surgical or adjuvant treatment due to high-risk pathologic features. There were no recurrences documented. Three patients developed cervical stenosis. The live birth rate was 85% and 16 (94%) of 17 patients had live births at term. CONCLUSION: Cervical conization with SLN biopsy appears to be a safe treatment option in selected patients with early cervical cancer. Future results of prospective trials may shed definitive light on fertility-sparing options in this group of patients.

Prospective assessment of urinary and bowel symptoms, and sexual function between laparoscopic assisted vaginal radical trachelectomy and radical hysterectomy.

OBJECTIVE: Radical trachelectomy is a valid alternative to radical hysterectomy in women with a desire to retain their fertility. Data regarding the oncological outcomes of radical trachelectomy are comparable with those of radical hysterectomy but information regarding urinary and sexual function is limited. The aim of this study was to prospectively evaluate and compare quality of life, urinary and bowel symptoms, and sexual dysfunction between patients who underwent laparoscopic assisted vaginal radical trachelectomy versus radical hysterectomy for early-stage cervical cancer. METHODS: Patients who underwent laparoscopic assisted vaginal radical trachelectomy or radical hysterectomy along with sentinel or systemic pelvic lymphadenectomy were included between May 2015 and January 2017. Patients were asked to complete a validated questionnaire (German pelvic symptom questionnaire) on bladder, bowel, prolapse, and sexual function, and total pelvic score, at least 48 hours before surgery and 6 months after surgery. RESULTS: A total of 51 patients were included. Of these, 26 patients (50.9%) underwent laparoscopic assisted vaginal radical trachelectomy and 25 (49.1%) underwent radical hysterectomy. No patient was converted to laparotomy. The majority of patients (76%) were diagnosed with International Federation of Gynecology and Obstetrics (FIGO 2018) stage 1B1 disease, with squamous cell carcinoma (54%) and grade II tumors (52%). Four patients (7.8 %) experienced perioperative complications (two grade II and two grade III complications according to the Clavien-Dindo classification). In the preoperative evaluation, the median scores for the four items of the questionnaire (bladder, bowel, prolapse, and sexual items) and total pelvic score were comparable between the two groups. The mean scores for radical hysterectomy and radical trachelectomy at the beginning of the study for bladder, bowel, prolapse, and sexual function were 0.93 versus 0.71, 0.71 versus 1.01, 0.12 versus 0.1, and 1.06 versus 1.0, respectively. On preoperative testing, the median scores for all four items of the questionnaire (pbladder=0.821, pbowel=0.126, pprolapse=0.449, psexual=0.965) and the total pelvic score (p=0.756) were comparable between the two groups. The radical hysterectomy group had worse total pelvic scores at the 6 month postoperative survey compared with baseline (p=0.03). There was no difference in bladder (p=0.07) or bowel symptoms (p=0.07) in the radical hysterectomy group comparing baseline with the 6 month assessment. Women undergoing radical hysterectomy experienced more urinary morbidity than women undergoing vaginal trachelectomy at 6 weeks (p=0.025). However, the mean bladder and pelvic scores in the 6 month control were comparable between patients who had and those who had not experienced urinary morbidity (pbladder=0.127, ptotal pelvic score=0.480). CONCLUSION: Patients undergoing laparoscopic assisted vaginal radical trachelectomy had similar pelvic scores in both the preoperative and postoperative periods. However, patients undergoing radical hysterectomy showed worse total pelvic scores on the postoperative assessment compared with the baseline evaluation. Urinary dysfunction in the early postoperative phase was more common in the radical hysterectomy group than in trachelectomy group.

Laparoscopic assessment improves case selection for exenterative surgery in recurrent cervical and endometrial cancer.

The objective of this study is to evaluate the role of laparoscopy in the case selection of patients for pelvic exenteration to treat recurrent cervical or endometrial cancer. Pelvic exenteration is a rare surgical procedure performed by specialised multidisciplinary surgical teams. We performed a review of 55 consecutive laparoscopies for patients being evaluated for possible exenterative surgery for recurrent cervical or endometrial cancer at a single centre in the UK with a significant exenterative surgical practice. All patients had no evidence of metastatic disease on imaging prior to the laparoscopy. Despite thorough radiological assessment laparoscopy detected peritoneal, nodal or extrapelvic metastases in 20.8% of cases. 5.6% of the patients who underwent exenterative surgery were found to have unresectable pelvic disease intraoperatively. In these cases, the extent of disease was not determined radiologically or during the initial exploratory laparotomy. In our view, laparoscopic assessment is an essential component of the pre-operative work up of patients with recurrent cervical or endometrial cancer being considered for exenterative surgery.Impact statementWhat is already known on this subject? Pelvic exenteration is potentially curative in cases of recurrent pelvic malignancy. Case selection is essential to determine those patients without metastases and with resectable pelvic disease - this will improve patient outcomes, avoid the unnecessary morbidity of major surgery, as well as the psychological consequences of abandoned procedures. The only two previous studies, published in 1998 (Plante and Roy 1998) and 2002 (Köhler et al. 2002) have shown laparoscopic assessment to be safe and improve case selection.What do the results of this study add? This study provides evidence that in the context of modern imaging modalities, including PET-CT scans, laparoscopic assessment continues to improve case selection for exenterative surgery.What are the implications of these findings for clinical practice and/or further research? This study provides further evidence of the benefit of laparoscopy in the assessment of patients being considered for exenterative surgery for recurrent pelvic cancer. Routine laparoscopy improves case selection and will enhance patient experiences and outcomes.

The validity of the subsequent pregnancy index score for fertility-sparing trachelectomy in early-stage cervical cancer.

OBJECTIVE: To evaluate timing and a prediction model for pregnancy in early-stage cervical cancer patients who underwent fertility-sparing trachelectomy. DESIGN: Retrospective cohort. SETTING: Academic multicenter. PATIENT(S): Women ages <45 years with clinical stage I-II cervical cancer were enrolled between 2009 and 2013 (n = 393). INTERVENTION(S): Planned fertility-sparing trachelectomy. MAIN OUTCOME MEASURE(S): Cumulative incidences and clinicopathological characteristics of those who developed subsequent pregnancy were examined. RESULT(S): There were 77 (21.6%) women who had subsequent pregnancies after fertility-sparing trachelectomy with 1-, 2-, and 5-year cumulative pregnancy rates of 2.8%, 6.2%, and 17.4%, respectively. The median time to develop subsequent pregnancy was 3.2 years. In a competing risk analysis, women had a higher risk of recurrent cancer than conception during the first 11 months postsurgery. On multivariable analysis, younger age, being married, and postoperative reproductive treatment were independently associated with an increased chance of developing a subsequent pregnancy. The subsequent pregnancy index (SPI) score to predict the likelihood of having pregnancy was proposed, and it was calculated based on age, marital status, and reproductive treatment (2, 2, and 4 points, respectively). Women with a higher SPI score had significantly higher subsequent pregnancy rates (5-year pregnancy rate; the score was 3 in 4.7% of cases; 4 to 5 in 11.3%; 6 to 7 in 27.4%; and 8 in 50.8%), but they had similar recurrence rates (5.0%). CONCLUSION(S): The SPI score proposed in our study is useful in predicting subsequent pregnancy in women with early-stage cervical cancer undergoing fertility-sparing trachelectomy.

A retrospective assessment of the safety and efficacy of laparoscopic radical hysterectomy in Japan during the early years following its introduction: a Japanese Gynecologic Oncology Group study (JGOG1081S).

OBJECTIVE: To evaluate the safety and efficacy of laparoscopic radical hysterectomy (LRH) for cervical cancer, in terms of morbidity and short-term oncologic outcome following LRH's introduction into Japan. METHODS: We conducted a retrospective analysis of patients with early-stage cervical cancer (FIGO staging IA2, IB1, and IIA1) who underwent LRH from Dec 2014 to Dec 2016. We assessed the morbidity, overall survival (OS) and recurrence-free survival (RFS), and prognostic factors for RFS. RESULTS: A total of 251 patients were included from 22 facilities across Japan. There were 8 cases of stage IA2 cervical cancer, 226 of IB1, and 17 of IIA1. The median operating time was 343 min and the median blood loss was 190 ml. Two patients (0.8%) had a postoperative complication with a Clavien-Dindo classification of grade 3 or higher. After a median follow-up time of 15.6 months, the 2-year RFS was 87.4%, and the 2-year OS was 97.8%. When the 2-year RFS rate was compared with whether the patient pathologically had tumors of less than 2 cm, versus 2 cm or more, the RFS was 95.8% and 80.4%, respectively. Multivariate analysis found that tumor size and the route of lymph node removal were independent prognostic factors for recurrence. CONCLUSION: When LRH was first introduced into Japan, we found that the route of lymph node removal was an independent prognostic factor for recurrence in addition to large tumors (≥ 2 cm). Our results suggest that prognosis may be secured by paying attention to the lymph node removal route.
