Radical Hysterectomy For Cervical Cancer Research Articles

Postoperative urinary retention by void trial methodology following radical hysterectomy for cervical cancer

ObjectivesRadical hysterectomy is the standard of care for management of early-stage cervical cancer and is associated with postoperative urinary retention. No clear consensus exists regarding optimal voiding trial methodology for mitigating postoperative urinary retention. Our objective was to evaluate the association between type of postoperative voiding trial and risk of urinary retention after radical hysterectomy for cervical cancer. MethodsWe conducted a retrospective analysis of patients undergoing radical hysterectomy for apparent early-stage cervical cancer (FIGO 2018 Stage IA2-IB2) between January 2014 and February 2023. We compared incidence of urinary retention and perioperative outcomes based on method of postoperative voiding trial (timed, autofill, or backfill). Multivariate logistic regression was used to determine association of type of void trial with absence of urinary retention within 30 days postoperatively. ResultsOf the 115 patients identified, 48 (41.8%) patients completed a timed void trial, 40 (34.7%) an autofill void trial, and 27 (23.5%) a backfill void trial. 44.3% of patients developed postoperative urinary retention with no differences based on void trial (p = 0.17). Urinary retention was more likely to resolve by 7 (p = 0.012) and 30 days (p = 0.01) for patients undergoing backfill voiding trials, compared to other trials. In multivariate models, backfill void trial was associated with absence of 30-day urinary retention, compared to other trials (aOR 15.1; 95% C.I. 1.5–154.9). ConclusionsRates of urinary retention following radical hysterectomy do not differ based on postoperative void trial methodology. A backfill void trial following radical hysterectomy may lead to increased rates of resolution of postoperative urinary retention.

Approach to radical hysterectomy for cervical cancer after the LACC trial and associated complications: a NSQIP study

BackgroundThe Laparoscopic Approach to Cervical Cancer (LACC) study results revolutionized our understanding of the best surgical management for this disease. Following its publication, guidelines state that the standard and recommended approach for radical hysterectomy is with an open abdominal approach. Nevertheless, the impact of the LACC trial on real-world changes in the surgical approach to radical hysterectomy remains elusive. ObjectiveWe aimed to study the trends and routes of radical hysterectomies and to evaluate post-operative complication rates before and after the LACC trial (2018). Study DesignThe National Surgical Quality Improvement Program registry was used to examine radical hysterectomies performed for cervical cancer between 2012-2022. We excluded vaginal radical hysterectomies and simple hysterectomies. The primary outcome measures were the trends in route of surgery [minimally invasive surgery (MIS) vs. laparotomy] and surgical complications rate, stratified by periods before and after the publication of the LACC trial in 2018 (2012-2017 vs. 2019-2022). The secondary outcome measure was major complications associated specifically with the different routes of surgery. ResultsOf the 3,611 patients included, 2,080 (57.6%) underwent laparotomy and 1,531 (42.4%) underwent MIS radical hysterectomy. There was a significant increase in the MIS approach from 2012 to 2017 (45.6% MIS in 2012 to 75.3% MIS in 2017, p<.001), and a significant decrease in MIS from 2018 to 2022 (50.4% MIS in 2018 to 11.4% MIS in 2022, p<.001).The rate of minor complications was lower in the period before the LACC trial [317 (16.9%) vs. 288 (21.3%), p=.002]. Major complications rate was similar before and after the LACC trial [139 (7.4%) vs. 78 (5.8%), p=.26]. The rates of blood transfusions and superficial surgical site infections were lower in the period before the LACC trial [137 (7.3%) vs. 133 (9.8%), p=.012 and 20 (1.1%) vs. 53 (3.9%), p<.001, respectively]. In a comparison of MIS vs. laparotomy radical hysterectomy during the entire study period, patients in the MIS group had lower rates of minor complications [190 (12.4%) vs. 472 (22.7%), p<.001] and the rate of major complications was similar in both groups [100 (6.5%) in the MIS group vs. 139 (6.7%) in the laparotomy group, p=.89]. In a specific complications analysis, the rates of blood transfusion and superficial surgical site infections were lower in the MIS groups (2.4% vs. 12.7%, and 0.6% vs. 3.4%, p<.001 for both comparisons) and the rate of deep incisional surgical site infections was lower in the MIS group (0.2% vs. 0.7%, p=.048). In a multiple logistic regression analysis, the route of radical hysterectomy was not independently associated with occurrence of major complications [aOR 95% CI 1.02 (0.63-1.65)]. ConclusionWhile the proportion of MIS radical hysterectomy decreased abruptly following the LACC trial, there was no change in the rate of major post-operative complications. In addition, hysterectomy route was not associated with major post-operative complications.

Heterotopic ovarian transplantation instead hormonal replacement therapy after radical hysterectomy for cervical cancer: case report and review of literature.

Only a few case reports have described heterotopic ovarian tissue transplantation (OTT) with the only objective of restoring ovarian function. Case report and review of the literature forreporting cases of heterotopic OTT with the only aim of restoring ovarian endocrine function. In a cancer survivor woman with a history of hysterectomy and bilateral oophorectomy for cervical cancer and because she poorly tolerated hormone replacement therapy (HRT), we performed a heterotopic OTT in a pelvic subcutaneous "pocket" after an OT cryostorage of 17years. A cyclic ovarian endocrine function started 3months after OTT with an immediate patient self-described improvement of her quality of life. A second OTT was performed 19months after, due to hot flushes recurrence and FSH increase. Despite a cyclic endocrine function, progesterone levels have always been low, resulting in a relative hyperoestrogenism state. In the future, the indications of heterotopic OTT could be spread in alternative to HRT. However, our data suggest that the heterotopic graft environment is less favorable to corpus luteum development, and further studies are needed to assay the best site of heterotopic graft, the optimal number of ovarian cortexfragmentsto graft, and the potential risk of relapse in case of malignant residual disease.

Safety of vaginal surgery for early-stage cervical cancer: A retrospective multicenter cohort study

ObjectiveAbdominal Radical hysterectomy (ARH) with pelvic lymph node assessment is considered the standard treatment for early-stage cervical cancer. Accepted routes have previously included laparoscopic or robotic approaches (LRH). Laparoscopy-assisted vaginal or vaginal radical hysterectomy (LVRH) are performed in some centers. The objective of this study is to compare surgical and oncological outcomes of LVRH, to laparoscopic and abdominal approaches. Design patients settingA retrospective multicenter analysis of consecutive cervical cancer cases who underwent a radical hysterectomy between 2007 and 2017 in eleven regional cancer centers across Canada. MeasurementsA comparison of patients stratified by surgical technique was undertaken. T-test, Wilcoxon rank-sum and chi-square were used to compare patient characteristics. Log-rank tests and Cox proportional hazards models were employed to compare recurrence and survival across surgical groups. Main resultsA total of 1071 patients with cervical cancer stage IA1 with lymphovascular invasion to stage IIIC (FIGO 2018) <4 cm were identified. Postoperative complication rate was lowest for women undergoing LVRH (9.1 %, vs 18.3 % and 22.1 % for minimally invasive and open respectively). During follow up, 114 women recurred, and 70 women died. 5-year recurrence-free survival was 85.4 % for LRH, 89.4 % for ARH and 92.2 % for LVRH. LVRH was not found to be associated with a higher risk of recurrence or death than ARH on multivariable analysis (aHR for recurrence 0.62, CI 0.21–1.77; aHR for death 0.63, CI 0.14–2.77) ConclusionIn this retrospective study, vaginal or laparoscopy-assisted vaginal radical hysterectomy for cervical cancer was associated with favorable perioperative and oncological outcomes.

Effectiveness of acupuncture on urinary retention after radical hysterectomy for cervical cancer in China: a systematic review and meta-analysis.

Cervical cancer is one of the most common malignant tumors worldwide. Radical hysterectomy is the first choice for patients with early-stage cervical cancer. Studies have suggested that acupuncture may be a more effective therapy for the prevention and treatment of urinary retention after radical hysterectomy. To systematically evaluate the clinical efficacy of acupuncture in the prevention and treatment of urinary retention after radical hysterectomy. We searched the Cochrane library, Web of science, PubMed, Embase, Chinese Biomedical Literature Database, Wanfang database, Wipu database, China National Knowledge Infrastructure Database and ClinicalTrials.gov with the time from inception until December 2023, to collect randomized controlled studies on the clinical efficacy of acupuncture for prevention and treatment of urinary retention after radical hysterectomy. Literature meeting criteria was screened for data extraction. Quality evaluation was performed according to the Cochrane Handbook for Systematic Reviews of Interventions. And meta-analysis was performed using RevMan5.3 and stata14.0 software. 22 Randomized controlled trials with 1,563 patients, 854 in treatment group and 709 in control group, were included totally. Meta-analysis results showed that: the total effective rate in acupuncture group was higher than that in control group, with a statistically significant difference [relative risk (RR)] = 1.43, 95% confidence interval (CI 1.22, 1.68), p < 0.0001; the rate of urinary tract infection in acupuncture group was lower than that in control group, with a statistically significant difference [RR] = 0.23, 95% CI (0.07, 0.78), p < 0.05; the time of indwelling urinary catheter was reduced in acupuncture group compared with control group, with a statistically significant mean difference = -3.45, 95% CI (-4.30, -2.59), p < 0.00001; the incidence of urinary retention was lower in acupuncture group than in control group, and the difference was statistically significant [RR = 0.37, 95% CI (0.27, 0.50), p < 0.00001]; the residual urine volume was reduced in acupuncture group compared with control group, with a statistically significant mean difference = -50.73, 95% CI (-63.61, -7.85), p < 0.00001. Acupuncture treatment based on conventional therapy can better prevent and improve urinary retention after radical hysterectomy for cervical cancer, could be a better option for them.

Effect of Pelvic Floor Function Exercises Based on the ERAS Concept on Lower Urinary Tract Symptoms after Radical Hysterectomy for Cervical Cancer: A Retrospective Cohort Study.

This study aimed to analyse the effect of pelvic floor function exercises based on the enhanced recovery after surgery (ERAS) concept on lower urinary tract symptoms after radical hysterectomy for cervical cancer. The retrospective study was conducted using clinical data of patients admitted to our hospital from January 2021 to December 2022 and underwent radical hysterectomy for cervical cancer. In accordance with the nursing method, the patients were divided into the routine group (conventional care) and the ERAS pelvic floor function exercise group, for which ERAS concept-based pelvic floor function exercises were carried out on the basis of the former group. The confounders between the two groups were matched by propensity score, and the scores of urination, pelvic floor muscle strength, lower urinary tract symptoms and quality of life (QoL) were compared between the two groups after matching. A total of 180 patients were included in the study, of whom 60 patients were identified after propensity score matching, consisting of 30 patients each in the ERAS and routine groups. The baseline characteristics of the two groups were balanced, and the difference was not statistically significant (p > 0.05). Compared with the routine group, the observation group showed significantly shorter first spontaneous urination time, greater first urination volume (p < 0.05), better pelvic floor muscle strength, considerably lower urinary tract symptoms and better QoL at discharge and 3 months after discharge (p < 0.05). Pelvic floor function exercises based on the ERAS concept can relieve lower urinary tract symptoms, accelerate urination and improve pelvic floor muscle strength and QoL after radical hysterectomy for cervical cancer.

VNOTES Radical Hysterectomy: A New Approach to Cervical Cancer

To demonstrate how a radical hysterectomy with sentinel node resection for cervical cancer can be performed via vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES). Demonstration of the technique in 10 steps. making use of narrated original video footage SETTING: The surgical treatment of cervical cancer is traditionally performed via one of the following techniques: Wertheim radical hysterectomy via laparotomy, Schauta radical hysterectomy vaginally, laparoscopic radical hysterectomy or robotic radical hysterectomy. The results of the LACC trial showed that minimally invasive radical hysterectomy was associated with lower rates of disease-free survival and overall survival than open radical hysterectomy among women with early-stage cervical Cancer [1]. For endometrial cancer, a vNOTES retroperitoneal approach to sentinel node resection was first published in 2019 [2]. Based on the experience with this approach and with Schauta-Stoeckel radical hysterectomy for cervical cancer [3], a new approach was developed to perform a radical hysterectomy via vNOTES whereby most of the procedure is performed retroperitoneally [4]. This video article demonstrates in 10 steps how a radical hysterectomy via vNOTES is performed. Radical hysterectomy via vNOTES demonstrated making use of original video footage of a 57-year-old woman operated on for cervical adenocarcinoma 7 weeks after a LEEP cone. The steps of the procedure are: 1. Vaginal cuff creation, 2. Development of lateral retroperitoneal space and sentinel node resection, 3. Uterine artery and vein transection, 4. Hypogastric nerve dissection, 5. Development of central retroperitoneal space and rectum dissection, 6. Posterior colpotomy, 7. Parametrium dissection, 8. Bladder pillar dissection, 9. Anterior colpotomy, 10. Salpingo-oophorectomy or salpingectomy. 3 Patients were so far treated by this new technique that allowed for good hemostatic control. vNOTES enables a potentially less invasive approach to radical hysterectomy performed largely retroperitoneally and completely transvaginally, leaving no visible scars. The endoscopic approach offers excellent visualization of the retroperitoneal and parametrial anatomy. This is a new approach that requires further validation and should only be performed in a research setting, taking into account the current reservations about endoscopic surgery for cervical cancer resulting from the LACC trial. VIDEO ABSTRACT.

A retrospective study of the effects of uterine manipulators on prognosis in patients with cervical cancer.

This retrospective study investigated the effects of uterine manipulator use during minimally invasive radical hysterectomy on prognosis in patients with cervical cancer. We collected clinical data on 762 patients with stage IA2 to IIB cervical cancer who underwent radical hysterectomy and pelvic lymphadenectomy in Chinese PLA General Hospital from 2009 to 2019. Kaplan-Meier analysis and log-rank tests were used to compare the 5-year overall survival rates between patients treated with and without a uterine manipulator. Patient demographics did not differ between the two groups. In addition, the incidence of lymphovascular space invasion, tumor size, pathologic types, the International Federation of Gynecology and Obstetrics stage, the histologic grade, and the rate of lymphatic metastases did not differ between the groups. Meanwhile, perioperative clinical indicators were similar in the groups. Furthermore, no significant differences in 5-year survival rates and survival curves were recorded between the groups among both all patients (84.5% vs. 85.6%) and early-stage patients (89.1% vs. 89.2%). The use of uterine manipulators during minimally invasive radical hysterectomy for cervical cancer did not affect clinicopathological markers or increase the risk of death.

Intermittent Catheterization Continuity Care on Bladder Function Recovery and Quality of Life in Patients After Radical Hysterectomy for Cervical Cancer: A Quasi-Experimental Study.

Bladder dysfunction is a common complication following radical hysterectomy, affecting patients' QOL. Exploring interventions, particularly IC continuity care, is crucial for identifying strategies to enhance postoperative outcomes. This study aimed to assess the impact of continuous intermittent catheterization (IC) care on bladder function recovery and quality of life (QOL) in patients undergoing radical hysterectomy for cervical cancer. The primary outcome measured was the time to bladder function recovery, with secondary outcomes comprising EORTC QLQ-C30 assessments at 3 and 6 months post-surgery, as well as EORTC QLQ-CX24 evaluations. Meanwhile, urinary complications, readmissions, and outpatient follow-up were also compared. Among the 128 participants, with 64 in each group, indwelling catheterization durations were similar. However, the IC continuity care group exhibited significantly shorter IC duration and bladder recovery time. This group demonstrated superior QOL, lower occurrence rates post-IC, reduced urethral injuries, and higher readmission and outpatient follow-up rates. This study underscores continuous IC care emerges as a beneficial intervention, facilitating accelerated bladder function recovery and improved QOL in patients following radical hysterectomy for cervical cancer.

Robotic radical hysterectomy for cervical cancer: current trends and controversies.

Minimally invasive radical hysterectomy (MIRH) is widely performed as a treatment for early-stage cervical cancer. However, in 2018, a randomized controlled trial (RCT) called the Laparoscopic Approach to Cervical Cancer (LACC) trial showed that MIRH had poorer oncologic outcomes compared to laparotomy. Since then, several clinical studies have supported this finding, and most surgeons now perform MIRH with limited surgical indications. However, most of the reported studies evaluated laparoscopic radical hysterectomy rather than robotic radical hysterectomy (RRH). Robotic surgery has advantages for complex surgical procedures in the deep and narrow pelvic cavity in cervical cancer, making it necessary to evaluate the benefits and potential harms of RRH individually. Based on this systematic review, RRH is a safe and effective alternative to abdominal approach for early-stage cervical cancer. RRH offers significant perioperative benefits, including reduced blood loss, shorter hospital stays, and fewer complications, without compromising oncologic outcomes such as overall survival and progression-free survival. Additionally, surgeons should aim to minimize tumor cell spillage into the peritoneal cavity by eliminating the use of uterine manipulators or vaginal colpotomy. Ongoing RCTs will reveal whether we can perform RRH without oncologic compromise in cervical cancer.

A multicenter noninferior randomized controlled study comparing the efficacy of laparoscopic versus abdominal radical hysterectomy for cervical cancer (stage IB3 and IIA2): study protocol of the LAUNCH 3 trial

BackgroundCervical cancer is and will remain to be an important health problem in China, especially with an increasing proportion of younger patients who has more specific needs. In China, surgery to remove tumor burden followed by postoperative treatment with radiotherapy and chemotherapy based on clinicopathologic factors may be the best choice for stages IB3 and IIA2 patients. Radical hysterectomy in cervical cancer has been a classic landmark surgery in gynecology. The current trial is designed to evaluate whether there is a difference between laparoscopic RH and abdominal RH in cervical cancer (stages IB3 and IIA2) patient survival under stringent operation standards and consistent surgical oncologic principles. This paper reports the rationale, design, and implementation of the trial.Methods/designThis is an investigator-initiated, prospective, randomized, open, blinded endpoint (PROBE) controlled trial. A total of 1104 patients with stage IB3 and IIA2 cervical cancer will be enrolled over a period of 3 years. Patients are randomized (1:1) to either the laparoscopic RH or the abdominal RH group. Patients will then be followed up for at least 5 years. The primary end point will be 5-year overall survival, and secondary endpoints include 5-year progression-free survival, recurrence, and quality of life measurements.DiscussionThe study results will provide more convincing evidence-based information for stages IB3 and IIA2 cervical cancer patients and their gynecologic cancer surgeons in their choice of surgical method.Trial registrationClinicalTrials.gov, NCT04939831, retrospectively registered on 25 June 2021.

Intracorporeal colpotomy using the Gutclamper as a novel clamping device to prevent tumor spillage during laparoscopic radical hysterectomy for cervical cancer.

Tumor cell spillage during the colpotomy has been suspected as one reason for poor oncologic outcomes in laparoscopic radical hysterectomy (LRH) for cervical cancer. To prevent such tumor spillage in LRH, we focused on use of a Gutclamper which is a device originally designed to clamp the colon and rectum during colorectal resections. A woman with stage IB1 cervical cancer underwent LRH using the Gutclamper. The Gutclamper was inserted into the abdominal cavity via 5-mm trocar, the vagina was clamped, and an intracorporeal colpotomy was performed caudal to this device. The Gutclamper can be used to clamp the vaginal canal and avoid the exposure of cervical tumor, regardless of the surgeon's skills or patient conditions. An intracorporeal colpotomy using the Gutclamper can contribute to the standardization of LRH.

Urinary retention between nerve-sparing radical hysterectomy and radical hysterectomy for cervical cancer: A meta-analysis.

This study intended to assess the urinary retention between nerve-sparing radical hysterectomy and radical hysterectomy in cervical cancer. Relevant studies were selected from databases of PubMed, Embase, Wanfang, and China National Knowledge Internet with the last report up to January 15, 2022. Hazard ratio (HR) and 95% confidence interval (CI) were chosen as the evaluation index. Heterogeneity was assessed using Cochran Q test and I2 test. Subgroup analysis was conducted based on areas and cancer types (primary and metastatic cancer). A total of 8 articles (retrospective cohort studies) were selected in the meta-analysis. There were significant correlations between nerve-sparing radical hysterectomy and radical hysterectomy in related with urinary retention (HR [95% CI] = 1.78 [1.37, 2.31], P < .001) and (HR [95% CI] = 2.49 [1.43, 4.33], P = .001) of cervical cancer patients. Egger test revealed a significant publication bias (P = .014). Sensitivity analysis via omitting 1 study at each time showed that omission of any study made significant difference (P < .05), indicating reliability and good stability for the analysis. Additionally, there were significant heterogeneities in most subgroups.

Risk factors for catheter–associated urinary tract infections following radical hysterectomy for cervical cancer

Radical hysterectomy is the mainstay of treatment for early-stage cervical cancer. Urinary tract dysfunction is one of the most common complications after radical hysterectomy, and prolonged catheterization has previously been defined as a significant risk factor for catheter-associated urinary tract infections. This study aimed to determine the rate of catheter-associated urinary tract infections after radical hysterectomy for cervical cancer, and to identify additional risk factors for developing catheter-associated urinary tract infections in this population. We reviewed patients who underwent radical hysterectomy for cervical cancer from 2004 to 2020 after institutional review board approval. All patients were identified from institutional Gynecologic Oncology surgical and tumor databases. The inclusion criterion was radical hysterectomy for early-stage cervical cancer. Exclusion criteria included inadequate hospital follow-up, insufficient records of catheter use in the electronic medical record, urinary tract injury, and preoperative chemoradiation. Catheter-associated urinary tract infection was defined as an infection diagnosed in a catheterized patient or within 48 hours of catheter removal, with significant bacteriuria (>103 cfu/mL) and symptoms or signs attributable to the urinary tract. Data analysis was performed using comparative analysis and univariate and multivariable logistic regression using Excel, GraphPad Prism, and IBM SPSS Statistics. Of the 160 included patients, 12.5% developed catheter-associated urinary tract infections. In univariate analysis, catheter-associated urinary tract infection was significantly associated with current smoking history (odds ratio, 3.76; 95% confidence interval, 1.39-10.08), minimally invasive surgical approach (odds ratio, 5.24; 95% confidence interval, 1.91-16.87), estimated surgical blood loss >500 mL (odds ratio, 0.18; 95% confidence interval, 0.04-0.57), operative time >300 minutes (odds ratio, 2.92; 95% confidence interval, 1.07-9.36), and increased duration of catheterization (odds ratio, 18.46; 95% confidence interval, 3.67-336). After adjusting for interactions and controlling for potential confounders with multivariable analysis, current smoking history and catheterization for >7 days were identified as independent risk factors for development of catheter-associated urinary tract infections (adjusted odds ratio, 3.94; 95% confidence interval, 1.28-12.37; adjusted odds ratio, 19.49; 95% confidence interval, 2.78-427). Preoperative smoking cessation interventions for current smokers should be implemented to decrease risk for postoperative complications, including catheter-associated urinary tract infections. In addition, catheter removal within 7 postoperative days should be encouraged in all women undergoing radical hysterectomy for early-stage cervical cancer in an effort to decrease infection risk.

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

BackgroundPrevious studies have suggested that higher surgeon volume leads to improved perioperative outcomes for oncologic surgery; however, the effect of surgeon volumes on surgical outcomes might differ according to the surgical approach used. This paper attempts to evaluate the effect of surgeon volume on complications or cervical cancer in an abdominal radical hysterectomy (ARH) cohort and laparoscopic radical hysterectomy (LRH) cohort.MethodsWe conducted a population-based retrospective study using the Major Surgical Complications of Cervical Cancer in China (MSCCCC) database to analyse patients who underwent radical hysterectomy (RH) from 2004 to 2016 at 42 hospitals. We estimated the annualized surgeon volumes in the ARH cohort and in the LRH cohort separately. The effect of the surgeon volume of ARH or LRH on surgical complications was examined using multivariable logistic regression models.ResultsIn total, 22,684 patients who underwent RH for cervical cancer were identified. In the abdominal surgery cohort, the mean surgeon case volume increased from 2004 to 2013 (3.5 to 8.7 cases) and then decreased from 2013 to 2016 (8.7 to 4.9 cases). The mean surgeon case volume number of surgeons performing LRH increased from 1 to 12.1 cases between 2004 and 2016 (P < 0.01). In the abdominal surgery cohort, patients treated by intermediate-volume surgeons were more likely to experience postoperative complications (OR = 1.55, 95% CI = 1.11–2.15) than those treated by high-volume surgeons. In the laparoscopic surgery cohort, surgeon volume did not appear to influence the incidence of intraoperative or postoperative complications (P = 0.46; P = 0.13).ConclusionsThe performance of ARH by intermediate-volume surgeons is associated with an increased risk of postoperative complications. However, surgeon volume may have no effect on intraoperative or postoperative complications after LRH.

Risk factors for and delayed recognition of genitourinary fistula following radical hysterectomy for cervical cancer: a population-based analysis.

This study aimed to identify the risk factors for genitourinary fistulas and delayed fistula recognition after radical hysterectomy for cervical cancer. This study was a retrospective analysis of data collected in the Major Surgical complications of Cervical Cancer in China (MSCCCC) database from 2004-2016. Data on sociodemographic characteristics, clinical characteristics, and hospital characteristics were extracted. Differences in the odds of genitourinary fistula development were investigated with multivariate logistic regression analyses, and differences in the time to recognition of genitourinary fistula were assessed by Kruskal-Wallis test. In this study, 23,404 patients met the inclusion criteria. Surgery in a cancer center, a women's and children's hospital, a facility in a first-tier city, or southwest region, stage IIA, type C1 hysterectomy, laparoscopic surgery and ureteral injury were associated with a higher risk of ureterovaginal fistula (UVF) (p<0.050). Surgery in southwest region, bladder injury and laparoscopic surgery were associated with greater odds of vesicovaginal fistula (VVF) (p<0.050). Surgery at cancer centers and high-volume hospitals was associated with an increase in the median time to UVF recognition (p=0.016; p=0.005). International Federation of Gynecology and Obstetrics (FIGO) stage IIA1-IIB was associated with delayed recognition of VVF (p=0.040). Intraoperative urinary tract injury and surgical approach were associated with differences in the development of UVFs and VVFs. Patients who underwent surgery in cancer centers and high-volume hospitals were more likely to experience delayed recognition of UVF. Patients with FIGO stage IIA1-IIB disease were more likely to experience delayed recognition of VVF.

Volume Index Measured Using Magnetic Resonance Imaging for Diagnosing Cervical Cancer Tumors

Diagnosis of cervical cancer with tumor diameter <2 cm using magnetic resonance imaging alone has not been investigated. Moreover, whether tumor volume can be used for diagnosing the true tumor diameter remains unknown. Here, we investigated the utility of early cervical cancer volume index in diagnosing cervical cancer with a tumor diameter of <2 cm, which can be treated using more conservative surgery. This single-center retrospective study analyzed women who underwent radical hysterectomy for cervical cancer with a tumor diameter of <2 cm and clinical stages IA2, IB1, IB2, IB3, and IIA1 at our institute between January 2009 and April 2022. The volume index, defined as the product of the maximum longitudinal diameter along the uterine axis, maximum anteroposterior diameter (thickness) on a sagittal section image, and maximum horizontal diameter on a horizontal section image, was evaluated using either T2-weighted magnetic resonance imaging or gadolinium-enhanced T1-weighted imaging. The receiver operating characteristic curve for the volume index was also calculated. The sensitivity and specificity of magnetic resonance imaging for measuring the tumor diameter were 0.92 and 0.84, respectively. The calculated cut-off value was 2.60, whereas the volume index area under the curve was 0.955, with a sensitivity of 0.92 and specificity of 0.93. Considering the specificity and low incidence of false-negative results, the volume index can be used for preoperative diagnosis of pT1B1 cervical cancer, which can be treated with more conservative surgery.
