Correlation Between Persistent HPV Infection and Vaginal Microecological Imbalance After Treatment of Cervical High-Grade Squamous Intraepithelial Lesion.

Objective: To analyze the association between persistent human papillomavirus (HPV) infection and vaginal microecological imbalance after surgical treatment of cervical high-grade squamous intraepithelial lesion (HSIL). Methods: This is a retrospective study, 180 cervical HSIL patients admitted to our hospital from May 2019 to May 2021 were selected, of these, 84 were treated with loop electrosurgical excision procedure (LEEP) and 96 with cold knife conization (CKC). Patients were followed up for HPV infection 1 year after surgery. There is a division into a persistent infection group (positive group) and a negative group based on the presence or absence of HPV, the detection technique was PCR amplification. The two groups were compared regarding preoperative HPV infection, vaginal micro-ecological indicators 1 year after surgery, and the correlation between persistent HPV infection and vaginal microecological imbalance. Results: At 1 year after surgery, among 180 cervical HSIL patients, 64 (35.56%) were persistently infected with HPV, with an age of (40.20 ± 4.85) years, including 36 (56.25%) with cervical intraepithelial neoplasia (CIN) grade II, 28 (43.75%) with cervical intraepithelial neoplasia (CIN) grade III, 116 (64.44%) with HPV negative, with an age of (40.22 ± 5.15) years, including 67 (57.76%) with CIN grade II and 49 (42.24%) with CIN grade III, the differences in age and CIN classification between the two groups were not statistically significant (P > .05). Preoperatively, 53 people (82.81%) with HPV viral load >100 RLU/CO in the HPV persistent infection group and 76 people (65.52%) with HPV viral load >100 RLU/CO in the HPV negative group, with statistically significant differences between the two groups (P < .05); The difference in HPV virus typing and HPV infection type between the two groups was not statistically significant (P > .05). At 1 year after surgery, the composition ratio of flora density class IV and flora diversity class IV were significantly higher in the HPV persistent infection group than in the HPV negative group, and the dominant bacteria were mainly gram-positive large bacillus, accounting for 83.33%, the difference between the two groups was statistically significant (P < .05); The differences in Nugent scores and pH values between the two groups were not statistically significant (P > .05). Logistic regression analysis showed that flora density, flora diversity, and dominant bacteria were all independent risk factors for persistent HPV infection after treatment in patients with HSIL (P < .05). Conclusion: After treatment of HSIL patients, clinical attention should be paid to monitoring of HPV infection but also to the changes in vaginal microecology, as timely correction of vaginal microecology can facilitate HPV regression and improve the patient's prognosis.

Meta-analysis of clinical efficacy of electroacupuncture versus conventional treatment for postoperative urinary retention in cervical cancer.

BACKGROUND: To conduct a meta-analysis on the clinical efficacy of electroacupuncture in the treatment of postoperative urinary retention in cervical cancer, and to provide a theoretical basis for the promotion of electroacupuncture in the treatment of this disease. METHODS: Computer searches of the Cochrane library, Web of science, PubMed, Embase, Chinese Biomedical Literature Database, Wanfang database, Wipu database, and China National Knowledge Infrastructure Database database were conducted to find randomized controlled trials on electroacupuncture for postoperative urinary retention recovery in cervical cancer, all from the time of database creation to October 2022. Two evaluators independently evaluated the quality of the included literature and extracted the data. Data were combined and analyzed using RevMan 5.4. RESULTS: A total of 21 Randomized controlled trials with 1532 patients, 789 in the treatment group and 743 in the control group, were included. One descriptive analysis was performed and 20 Meta-analyses were performed. Meta-analysis results showed that: The electroacupuncture group was more effective than the control group in promoting recovery from urinary retention after cervical cancer, with a statistically significant difference [relative risk (RR)] = 1.32, 95% confidence interval (CI 1.26, 1.39), P < .00001; The duration of indwelling catheterization was reduced in the electroacupuncture group compared with the control group, with a statistically significant standard mean difference = -1.43, 95% CI (-1.62, -1.24), P < .00001; The healing rate in the electroacupuncture group was higher than that in the control group, with a statistically significant difference [RR] = 1.92, 95% CI (1.59, 2.30), P < .00001; The rate of urinary tract infection in the electroacupuncture group was lower than that in the control group, with a statistically significant difference [RR] = 0.22, 95% CI (0.10, 0.45), P < .00001. The incidence of urinary retention was lower in the electroacupuncture group than in the control group, and the difference was statistically significant [RR = 0.26, 95% CI (0.18, 0.39), P < .01]. CONCLUSION: Electroacupuncture can promote the recovery of urinary retention after cervical cancer surgery, and can improve the healing rate of patients after surgery, reduce the occurrence of urinary tract infection and shorten the duration of indwelling catheterization.

[Clinical application of laparoscopic sentinel lymph node mapping in early staged cervical cancer].

Objective: To investigate the application of sentinel lymph node biopsy (SLNB) in early-staged cervical cancer by laparoscopy. Methods: It was a prospective, single-arm, single-center clinical study. Seventy-eight cases of cervical cancer patients were collected from July 2015 to December 2018 at the Fourth Hospital of Hebei Medical University. All the patients were injected with tracer into the disease-free block of cervical tissue after anesthesia by the same surgeon who learned sentinel lymph node (SLN) mapping technique in Memorial Sloan-Kettering Cancer Center, and underwent SLN mapping followed by complete pelvic lymphadenectomy. Moreover, all the dissected lymph nodes were stained with hematoxylin eosin staining (HE) pathological examination. Besides, the negative SLN on hematoxylin-eosin staining were detected by immunohistochemistry cytokeratin staining micro-metastasis. To analyze the distribution, detection rate, false negative rate the sensitivity and negative predictive value of the SLN in early-staged cervical cancer by laparoscopy, and explore the value of SLN mapping in predicting the lymph nodes metastasis in early-staged cervical cancer. Results: The overall detection rate of SLN in cervical cancer was 99% (77/78), bilateral detection rate was 87% (68/78). The average of 12.4 lymph node (LN) and 3.6 SLN were dissected for each patients each side. SLN of cervical cancer were mainly distributed in the obturator space (61.5%, 343/558), followed by external iliac (23.5%, 131/558), common iliac (7.3%, 41/558), para-uterine (3.8%, 21/558), internal iliac (2.2%, 12/558), para abdominal aorta (1.1%, 6/558), and anterior sacral lymphatic drainage area (0.7%, 4/558). Fourteen cases of LN metastasis were found among all 78 cases. There were a total of 38 positive LN, including 26 SLN metastasis and 12 none sentinel LN metastasis. Through immunohistochemical staining and pathological ultra-staging, 1 SLN was found to be isolated tumor cells (ITC), and 5 SLNs were found to be micro-metastases (MIC), accounting for 23% (6/26) of positive SLN. SLN mapping with pathological ultra-staging improved the prediction of LN metastasis in cervical cancer (2/14). Metastatic SLN mainly distributed in the obturator space (65%, 17/26), peri-uterine region (12%, 3/26), common iliac region (15%, 4/26), and external iliac region (8%, 2/26). The consistency of the diagnosis of lymph node metastasis by SLN biopsy and postoperative retroperitoneal lymph node metastasis showed that the Kappa value was 1.000 (P<0.001), indicated that the metastasis status of SLN and retroperitoneal lymph node were completely consistent. The sensitivity, specificity, accuracy, false-negative rate, and negative predictive value of SLN biopsy in the diagnosis of lymph node metastasis were 100%, 100%, 100%, 0, and 100%, respectively. Conclusions: SLN in early-staged cervical cancer patients were mainly distributed in the obturator and external iliac space, pathalogical ultra-staging of SLN could improve the prediction of LN metastasis. Intraoperative SLN mapping is safe, feasible and could predict the state of retroperitoneal LN metastasis in early-staged cervical cancer. SLNB may replace systemic pelvic lymphadenectomy.

Effect of Comprehensive Care Based on Appropriate Chinese Medicine Techniques on Urinary Retention and Bladder Function Recovery after Total Hysterectomy in Patients with Cervical Cancer.

Objective: To investigate the effect of comprehensive care based on appropriate Chinese medicine techniques on urinary retention and bladder function recovery after total hysterectomy in patients with cervical cancer. Methods: A total of 148 cases admitted after radical hysterectomy for cervical cancer from January 2019 to early September 2019 were used as the observation sample and were divided into control and experimental groups based on a randomized double-blind method. There were 74 cases each. The control group was given comprehensive care, and the experimental group was given comprehensive care based on appropriate Chinese medicine techniques. The intervention period was 2 weeks after surgery. The recovery rate of bladder function and the occurrence of urinary retention were compared between the two groups, and the duration of postoperative retention of urinary catheter, the amount of residual urine, and the feeling of urination were counted. Results: The experimental group had better urinary catheter retention time, time to first spontaneous voiding, time to get out of bed, and time to anal discharge than the control group; the experimental group had a higher rate of good bladder function recovery than the control group and better bladder recovery time, residual urine volume, and incidence of urinary retention than the control group; the patients in the experimental group had better UDI-6 scores. Conclusion: The implementation of comprehensive care based on appropriate Chinese medicine techniques can relieve patients' difficulty in urination and improve their quality of life.

Ultrasound guidance for cervical implantation.

Ultrasound can provide real-time imagery without the risk of radiation exposure, and it is widely available at a relatively low cost. It can provide updated three-dimensional information that can improve the physician's spatial awareness during a brachytherapy procedure for cervical cancer. There is mounting evidence demonstrating the numerous benefits of ultrasound-guided brachytherapy in the published literature. This evidence supports its routine use to improve the safety and the effectiveness of cervical brachytherapy. In this report we will review various methods in which ultrasound imaging has been used during cervical brachytherapy. We also include a description of our own institutional approach to ultrasound-guided cervical implementation that has been in use for all cervical brachytherapy procedures over the past two decades.

The effectiveness of mindfulness-based stress reduction intervention on alleviating anxiety and depression in postoperative patients with cervical cancer: A protocol for systematic review and meta-analysis.

BACKGROUND: Surgical treatment for cervical cancer, as a stressor, largely leads to strong psychological reactions to stress like anxiety and depression. Whether mindfulness-based stress reduction (MBSR) can alleviate anxiety and depression in patients after cervical cancer surgery is controversial. Therefore, we aim to perform a meta-analysis involving randomized controlled trials analyzing the effect of MBSR on alleviating anxiety and depression in patients after cervical cancer surgery, thus providing evidence-based medical evidences for nonpharmacological interventions. METHODS: Randomized controlled trials analyzing the effect of MBSR on alleviating anxiety and depression in patients after cervical cancer surgery will be searched in online databases, including Cochrane Central Register of Controlled Trials Repositories, PubMed, Embase, Web of Science, Chinese Science Citation Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Chinese Scientific Journal Database, and Wan Fang Data. After screening eligible studies, we will perform a meta-analysis on the effect of MBSR on alleviating anxiety and depression in patients after cervical cancer surgery. RESULTS: The results of this meta-analysis will be submitted to a peer-reviewed journal for publication. CONCLUSION: This study will provide reliable evidence-based evidences for the effects of MBSR on alleviating anxiety and depression in patients after cervical cancer surgery. ETHICS AND DISSEMINATION: Ethical approval was not required for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences, and shared on social media platforms. OSF REGISTRATION NUMBER: DOI 10.17605/OSF.IO/EXUM3.

In vivo and in vitro study of the potential hazards of surgical smoke during cervical cancer treatment with an ultrasonic scalpel.

OBJECTIVE: To explore the composition and potential hazards of cervical cancer surgical smoke generated by ultrasonic scalpels. METHODS: Surgical smoke was collected during the cutting and coagulation of cervical cancer xenograft tumors using an ultrasonic scalpel. Surgical smoke-filtered cells were cultured and subcutaneously injected into nude mice. Cell morphology and viability were assessed by HE, Pap and trypan blue staining. HPV DNA in surgical smoke samples was identified by PCR. HPV transmission was determined by culturing HPV-negative C33A cells in HPV-positive surgical smoke-filtered medium. The cytotoxicity of surgical smoke to small airway epithelial cells (SAECs) and THP-1 cells was determined by CCK-8, MTS and LDH release assays. Volatile organic compounds (VOCs), which are present in cervical cancer surgical smoke samples obtained by laparoscopic hysterectomy, were analyzed by gas chromatography-mass spectrometry (GC-MS). RESULTS: Cellular debris and epithelioid cells were found in surgical smoke, but no malignant cells were observed. HPV DNA was identified in all smoke samples, and HPV genotypes were matched to those in cervical cancer cells. Coculture with HPV-positive surgical smoke-filtered medium induced an 83% (15 of 18) HPV positivity rate in C33A cells. Subculture in normal medium decreased this rate to 50% (9 of 18). The proliferation of SAECs and THP-1 cells was inhibited by smoke-filtered medium in a time-dependent manner. The concentration of total VOCs, especially benzene, toluene and xylene, in surgical smoke exceeded the standard for good indoor air quality. CONCLUSION: Cervical cancer surgical smoke contains HPV and VOCs and exhibits cytotoxicity and infectivity in vitro. Surgical smoke is an occupational hazard to health care workers.

Outcomes of Minimally Invasive versus Open Radical Hysterectomy for Early Stage Cervical Cancer Incorporating 2018 FIGO Staging.

STUDY OBJECTIVE: To compare outcomes after minimally invasive surgery (MIS) vs open radical hysterectomy for early stage cervical cancer incorporating 2018 Federation of Gynecology and Obstetrics (FIGO) staging. DESIGN: A retrospective analysis. SETTING: A single teaching hospital. PATIENTS: Patients after radical hysterectomy for stage IA1 with lymphovascular invasion, IA2, or IB1 squamous, adenosquamous, or adenocarcinoma of the cervix between 2007 and 2018, mirroring the Laparoscopic Approach to Cervical Cancer trial criteria. INTERVENTIONS: The use of MIS surgery for performing radical hysterectomy. MEASUREMENTS AND MAIN RESULTS: The outcomes were compared between patients undergoing MIS vs open approaches. A total of 126 patients met the inclusion criteria. The approach was open in 44 patients (35%) and MIS in 82 patients (65%); 49% were laparoscopic and 51% were robotic. Distribution based on the 2009 FIGO staging showed 1 stage IA1 with lymphovascular invasion, 15 stage IA2, and 110 stage IB1 patients. Although not statistically significant, the 3-year disease-free survival (DFS) was higher in the open compared to the MIS group (95% vs 87%; p = .17), and the overall survival was higher in the open compared to the MIS group (97% vs 92%; p = .25). Fourteen patients whose disease recurred were Stage IB1 by FIGO 2009 staging; 11/14 were reclassified to a higher stage by 2018 FIGO staging (5/5 open, 6/9 MIS). Adjuvant therapy was recommended for all these patients based on the Sedlis criteria (10/14) or other risk factors (4/14). Despite this, only 1/9 of MIS patients whose disease recurred received adjuvant therapy compared with 3/5 patients whose disease recurred in the open group (p = .05). CONCLUSION: In a cohort of patients similar to that of the Laparoscopic Approach to Cervical Cancer trial, 2018 FIGO staging may be useful to refine indications for MIS radical hysterectomy in early stage cervical cancer. However, disparate outcomes between MIS and open approaches may be explained by differences in compliance with National Comprehensive Cancer Network guidelines for adjuvant therapy.

Controversies in Sentinel Lymph Node Biopsy for Gynecologic Malignancies.

OBJECTIVE: Sentinel lymph node (SLN) biopsy represents an evolution in the advancement of minimally invasive surgical techniques for gynecologic cancers. Prospective and retrospective studies have consistently shown its accuracy in the detection of lymph node metastases for endometrial and cervical cancers. However, consistent with any emerging surgical technique in the early phases of adoption, new questions have arisen regarding its application and impact. This paper served as a scoping review to identify the key controversies that have arisen in the field of SLN biopsy for endometrial and cervical cancers. DATA SOURCES: Several key controversies were identified, and PubMed, the Cochrane Library (cochranelibrary.com) advanced search function, and the National Comprehensive Cancer Network guidelines were searched for supporting evidence. These included search terms such as "the accuracy of SLN biopsy for high grade endometrial cancer or cervical cancers >2-cm," "cost effectiveness of SLN biopsy for gynecologic cancers," "clinical significance of low volume metastases in endometrial cancer," "morbidity of SLN biopsy for endometrial and cervical cancer," and "impact on cancer survival of SLN biopsy for endometrial and cervical cancer." METHODS OF STUDY SELECTION: Studies were selected for review if they included significant numbers of patients, were level I evidence, or were prospective trials. Where this level of evidence failed to exist, seminal observational series that were published in high-quality journals were included. TABULATION, INTEGRATION, AND RESULTS: Similar studies were listed and subcategorized and cross-compared, excluding those that included repeated analyses of the same patient populations. The relevant clinical trials or observational studies were clustered and reviewed for each chosen controversy. Adequate evidence supports the accuracy of SLN biopsy in the staging of high-grade endometrial cancer and cervical cancer, and it seems to be a cost-effective strategy for invasive endometrial cancer. Conclusive evidence was lacking with respect to the oncologic outcomes related to SLN biopsy, the impact on patient morbidity, and whether clinicians should treat isolated tumor cells in SLNs with adjuvant therapy. CONCLUSION: SLN biopsy is an accepted staging strategy for cervical and endometrial cancer surgery; however, controversies remain in how it can be applied with the most safety and efficacy. These ultimately need to be resolved with further clinical trials and observations of larger series of patients.

Syringe or mask? Loop electrosurgical excision procedure under local or general anesthesia: a randomized trial.

BACKGROUND: Loop electrosurgical excision procedure may be performed under local anesthesia or general anesthesia, and practice patterns differ worldwide. No randomized head-to-head comparison has been published to confirm or refute either practice. OBJECTIVE: This study aimed to compare loop electrosurgical excision procedure under local anesthesia vs general anesthesia regarding patient satisfaction and procedure-related outcomes such as rates of involved margins, complications, pain, and blood loss. STUDY DESIGN: Consecutive women referred to our colposcopy unit were recruited. Loop electrosurgical excision procedure was performed under local anesthesia with 4 intracervical injections of bupivacaine hydrochloride 0.5% or under general anesthesia with fentanyl, propofol, and a laryngeal mask with sevoflurane maintenance. The primary endpoint was patient satisfaction assessed on the day of surgery and 14 days thereafter using a Likert scale (score 0-100) and a questionnaire. Secondary endpoints included rates of involved margins, procedure-related complications, pain, blood loss, and surgeon preference. Results were compared using nonparametric and chi-square tests. RESULTS: Between July 2018 and February 2020, we randomized 208 women, 108 in the local anesthesia arm and 100 in the general anesthesia arm. In the intention-to-treat analysis, patient satisfaction did not differ between the study groups directly after surgery (Likert scale 100 [90-100] vs 100 [90-100]; P=.077) and 14 days thereafter (Likert scale 100 [80-100] vs 100 [90-100]; P=.079). In the per-protocol analysis, women in the local anesthesia arm had significantly smaller cone volumes (1.11 cm3 [0.70-1.83] vs 1.58 cm3 [1.08-2.69], respectively; P<.001), less intraoperative blood loss (Δhemoglobin, 0.2 g/dL [-0.1 to 0.4] vs 0.5 g/dL [0.2-0.9]; P<.001), and higher satisfaction after 14 days (100 [90-100] vs 100 [80-100]; P=.026), whereas surgeon preference favored general anesthesia (90 [79-100] vs 100 [90-100], respectively; P=.001). All other secondary outcomes did not differ between groups (resection margin status R1, 6.6% vs 2.1% [P=.26]; cone fragmentation, 12.1% vs 6.3% [P=.27]; procedure duration, 151.5 seconds [120-219.5] vs 180 seconds [117-241.5] [P=.34]; time to complete hemostasis, 60 seconds [34-97] vs 70 seconds [48.25-122.25] [P=.08]; complication rate, 3.3% vs 1.1% [P=.59]). In a multivariate analysis, parity (P=.03), type of transformation zone (P=.03), and cone volume (P=.02) and not study group assignment, age, body mass index, and degree of dysplasia independently influenced the primary endpoint. CONCLUSION: Loop electrosurgical excision procedure under local anesthesia is equally well tolerated and offers patient-reported and procedure-related benefits over general anesthesia, supporting the preferred practice in some institutions and refuting the preferred practice in others.

A rare cause of sudden chest pain and dyspnea: A CARE-compliant case report of Chilaiditi syndrome.

RATIONALE: Chilaiditi syndrome is a rare disorder characterized by a broad spectrum of (gastro-intestinal) symptoms caused by interposition of a segment of bowel between the liver and the diaphragm. Most cases present with abdominal symptoms and the morbidity tend to increase with age. PATIENT CONCERNS: Here we present a rare case of Chilaiditi syndrome. An elderly postmenopausal woman developed unresolved postoperative respiratory symptoms and chest pain. Chest auscultation revealed considerable attenuation of respiratory sounds. She showed postoperative increase in D-dimer level and sudden onset of dyspnea. DIAGNOSES: Considering the presence of atelectasis in the middle and lower lobes of the right lung, bedside fiberoptic bronchoscopy was performed immediately to rule out bronchial phlegm embolism. However, no phlegm embolism was found in the left lung, and a small amount of yellow-white mucus was seen in the upper lobe of the right lung. Due to external pressure, the lumen of the middle and lower lobes of the right lung was obviously narrowed. INTERVENTIONS: The patient was placed in a semi-sitting position and a tube was passed through the anus to decompress the intestinal cavity; in addition, she received potassium supplementation. OUTCOMES: The patient's symptoms improved markedly. Chest and semi-supine abdominal plain radiographs showed enhanced lung markings, shadows in the left lower lung lobes, elevation of the right diaphragm, and small amount of pneumoperitoneum. The patient recovered after 5 days of continuous treatment and was discharged. LESSONS: Emergency computed tomographic pulmonary angiography may facilitate the diagnosis of Chilaiditi syndrome, especially in the postoperative setting. Occurrence of Chilaiditi syndrome in this patient was likely associated with surgical factors. Appropriate investigations and clear identification of etiology are essential for successful treatment.

Complementary surgery for cervical cancer patients inadequately treated with extrafacial hysterectomy.

OBJECTIVE: To evaluate surgical outcomes and survival outcomes of cervical cancer patients who underwent complementary surgery after an extrafacial hysterectomy METHODS: Patients with cervical cancer, who underwent extrafacial hysterectomy initially and thereafter underwent complementary surgery were reviewed retrospectively. Complementary surgery consisted of radical parametrectomy, proximal vaginectomy and pelvic lymphadenectomy. RESULTS: Twenty patients were evaluated. Histopathologic subtype was squamous cell carcinoma in twelve patients, adenocarcinoma in six patients and adenosquamous carcinoma in two patients. Route of surgery was laparotomy in 19 patients and laparoscopy in one patient. Two patients were staged as stage 1A2, nine were staged as stage 1B1, four were staged as stage 1B2, one was staged as stage 2A1, one was staged as stage 2B and three were staged as stage 3C1. The median tumor size was 16.5 (Range, 4-40) mm. Grade ≥ 3 complications related to surgery occured in 8 (40%) patients. Four of them were managed intraoperatively and recovered problem free. Remaining four (20%) needed reoperation. Pathology reports revealed involvement of parametrium in one (5%) patient, involvement of the proximal vagina in one (5%) patient, matastasis to pelvic lymph nodes in 3 (15%) patients. Five (25%) patients received adjuvant radiotherapy. Consequently, 5-year and 10-year cumulative survival was calculated as 94%. CONCLUSION: Complementary surgery and radiotherapy show similar oncologic outcomes in patients with early-stage cervical cancer who had undergone simple hysterectomy initially. Complementary surgery is associated with slightly higher rate of morbidity compared with radiotherapy, however significant proportion of complications can be noticed and repaired intraoperatively.

LLETZ make it simple: Anxiety, pain and treatment outcomes with outpatient large loop excision of the transformation zone under local anaesthesia.

BACKGROUND: Large loop excision of the transformation zone (LLETZ) is the preferred treatment for cervical intraepithelial neoplasia due to its effectiveness and ability to be performed in an outpatient setting under local anaesthesia (LA). Although current guidelines recommend that most LLETZ can be performed under LA, there is paucity in clinical data of patients' perspectives of outpatient LLETZ. AIM: Determining patient acceptability of outpatient LLETZ through assessment of anxiety and pain scores, and comparing treatment outcomes with current standards in terms of margins status, negative histology, short-term morbidity rates and follow-up attendance. MATERIALS AND METHODS: This study was conducted at a tertiary hospital over two years (2014-2016). Patients undergoing outpatient LLETZ completed a three-part questionnaire (before, immediately after and 4-6 weeks post-procedure). RESULTS: One hundred and five patients underwent outpatient LLETZ. Mean pain score was 2 (range 0-8). Pre-procedure anxiety was common but most resolved post-procedure. Women who did not have a prior LLETZ discussion were more likely to report moderate-severe anxiety levels pre-procedure, compared with women who did (odds ratio 3.00, 95% CI 1.11-8.09, P = 0.030). There were no differences found in pain scores when comparing pre-procedure anxiety levels, prior discussion of LLETZ or mode of anaesthesia. Specimen margins were involved in 42.9%. No association was found between positive cervical margin status and age, pre-procedure anxiety or post-procedure pain scores. Most patients were satisfied and attended follow-up appointments. CONCLUSION: Large loop excision of the transformation zone under LA is a well-tolerated procedure with high satisfaction and follow-up rates. Clinicians need to initiate early discussions regarding treatment to minimise procedure-related anxiety.

Effectiveness of modified complex decongestive physiotherapy for preventing lower extremity lymphedema after radical surgery for cervical cancer: a randomized controlled trial.

BACKGROUND: There is a lack of evidence in support of any prophylactic measure to prevent secondary lower extremity lymphedema after radical hysterectomy among patients with cervical cancer. This study aimed to determine the effectiveness of modified complex decongestive physiotherapy in reducing the risk of secondary lower extremity lymphedema after radical surgery. METHODS: A randomized single-blind clinical trial was conducted in 120 patients with cervical cancer who underwent laparoscopic radical hysterectomy with pelvic lymphadenectomy between January 2016 and April 2017 in the Obstetrics and Gynecology Hospital of Fudan University, Shanghai, China. Participants were randomly assigned to a modified complex decongestive physiotherapy intervention group (n=60) or control group (n=60). The intervention group received a modified complex decongestive physiotherapy program, which included manual lymph drainage, compression hosiery, regular exercise, and health education. The control group only received a health education program. The main outcome was the incidence of secondary lower extremity lymphedema. RESULTS: A total of 117 patients with cervical cancer completed a 1-year follow-up. Twenty-eight (23.9%) patients developed secondary lower extremity lymphedema (20 (34.5%) patients in the control group and 8 (13.6%) in the intervention group). The incidence of secondary lower extremity lymphedema was significantly higher in the control group than in the intervention group (p=0.008; OR 0.30 (95% CI 0.12 to 0.75). The median percentage of excess volume was significantly less in the intervention group (2.1%, IQR 0.5-3.4%) than in the control group (2.96%, IQR 1.1-4.98%); (p=0.042). The mean (SD) onset time of lymphedema was 8 (2.00) months vs 4.6 (2.82) months in the intervention and control groups, respectively (p=0.004). CONCLUSIONS: This randomized trial showed that modified complex decongestive physiotherapy is effective for preventing lower extremity lymphedema in patients with cervical cancer after laparoscopic radical hysterectomy with pelvic lymphadenectomy.

Frozen section examination of sentinel lymph nodes can be used as a decisional tool in the surgical management of early cervical cancer.

INTRODUCTION: Sentinel lymph node (SLN) detection has been shown to be accurate in detecting lymph node involvement in early-stage cervical cancer. The objective of this study was to evaluate the accuracy of frozen section examination in the assessment of SLN status, with the aim of adequately driving the intra-operative decision. METHODS: We designed a retrospective study including patients from two comprehensive cancer centers between January 2001 and December 2018 with early-stage cervical cancer (IA1-IB2 according to International Federation of Gynecology and Obstetrics (FIGO) 2018) undergoing SLN dissection. The SLN procedure was performed using a cervical injection with technetium-99m combined with blue dye or indocyanine green in most cases. RESULTS: A total of 176 patients fulfilled inclusion criteria. Bilateral mapping was detected in 153 (86.7%) of them. Nineteen of these patients (12.4%) had SLN involvement: 13 with macrometastases, three with micrometastases and three with isolated tumor cells (ITC). Macrometastatic disease was missed on frozen section in 3/13 FIGO 2018 stage IIIC patients. The three patients with ITC were also missed by frozen section examination.Considering only macrometastases as lymph node involvement, frozen section sensitivity was 76.9% (95% CI 49.7 to 91.8) and negative predictive value (NPV) was 97.9% (95% CI 94.0 to 99.3) in patients with bilateral detection. Including micrometastases, sensitivity was 81.2% (95% CI 57.0 to 93.4) and NPV remained at 97.9% (95% CI 93.9 to 99.3). CONCLUSIONS: With a prevalence of final-stage IIIC in patients with pre-operative early-stage cervical cancer of the order of 10% in this series, the NPV of frozen section examination of SLN is very high, with an inferior limit of the CI superior to 94%. Diagnostic accuracy remains acceptable even if micrometastases are considered. The impact of missed ITC has not been established. Frozen section examination can be incorporated in the intra-operative decision algorithm.

Pilot in vitro and in vivo study on a mouse model to evaluate the safety of transcutaneous low-frequency electrical nerve stimulation on cervical cancer patients.

INTRODUCTION AND HYPOTHESIS: To clarify whether the pulse electrical field (PEF) caused by transcutaneous low-frequency nerve electrical stimulation (TENS) enhances the proliferation of cervical cancer cells, leading to recurrence and metastasis, and the effect of such a PEF on a cervical cancer mouse model. METHODS: 1. In vitro experiment: SiHa cervical cancer cells treated with one session of microsecond PEFs for 30 min were divided into four groups: three experimental groups and the control group. Cell proliferation and migration were determined by CCK-8 proliferation and Transwell chamber Matrigel migration assay. 2. In vivo experiment: A mouse cancer model was established by subcutaneous implantation of SiHa cells that were then were randomly divided into the TENS group and control group. The former group received one session of TENS treatment and the control group received a sham pulse. The growth trend and tumor volume of each group were compared 28 days after PEF treatment. The proliferation and apoptosis of the tumor were determined by an immunohistochemical method. RESULTS: (1) The CCK-8 proliferation assay and cell migration ability showed no difference after PEF stimulation treatment (F = 2.478, P = 0.136 > 0.05 and F = 0.364, P = 0.779). (2) Tumor growth, size and weight showed no significant difference between the two groups. (3) Expression of VEGF, CD34, caspase-3 and Ki-67 in the tumor tissue showed no significant difference between the two groups. CONCLUSIONS: In vitro and in vivo experiments (mice) showed that the PEF created by TENS had no effect on the proliferation and migration of SiHa cervical cancer cells and also had no effect on the tumor growth, tumor cell apoptosis and proliferation.

Laparoscopic hand-assisted Miami Pouch after pelvic exenteration in 10 steps.

BACKGROUND: Improvements in surgical technique of pelvic exenteration have mainly occurred in the reconstructive phase of the procedure. Quality of life seems to be improved when performing continent rather than non-continent urinary diversion [1]. Unfortunately, Miami continent urinary pouch is a surgical technique not frequently used among surgeons. METHODS: This video illustrates the creation of a laparoscopic hand-assisted Miami Pouch in 10 consecutive steps. We present the case of a patient with an isolated central pelvic recurrence of cervical cancer who underwent a laparoscopic anterior pelvic exenteration, which is not included in the film. The surgery was performed by an experienced oncological surgeon in a French comprehensive cancer center. RESULTS: We split the surgical technique in the 10 following steps: CONCLUSIONS: Miami Pouch is a urinary reconstructive procedure that can improve quality of life after pelvic exenteration. As it has been previously reported, this film illustrates the feasibility of laparoscopic hand-assisted Miami Pouch after laparoscopic anterior pelvic exenteration [2,3]. A step-by-step comprehensive standardization of surgical techniques shortens learning curve of training surgeons [4].

Early experiences in integrating cervical cancer screening and treatment into HIV services in Zomba Central Hospital, Malawi.

Background: Malawi has the highest rate of cervical cancer globally and cervical cancer is six to eight times more common in women with HIV. HIV programmes provide an ideal setting to integrate cervical cancer screening. Methods: Tisungane HIV clinic at Zomba Central Hospital has around 3,700 adult women receiving treatment. In October 2015, a model of integrated cervical cancer screening using visual inspection with acetic acid (VIA) was adopted. All women aged 20 and above in the HIV clinic were asked if they had cervical cancer screening in the past three years and, if not, were referred for screening. Screening was done daily by nurses in a room adjacent to the HIV clinic. Cold coagulation was used to treat pre-cancerous lesions. From October 2016, a modification to the HIV programme's electronic medical record was developed that assisted in matching numbers of women sent for screening with daily screening capacity and alerted providers to women with pre-cancerous lesions who missed referrals or treatment. Results: Between May 2016 and March 2017, cervical cancer screening was performed in 957 women from the HIV clinic. Of the 686 (71%) women who underwent first ever screening, 23 (3.4%) were found to have VIA positive lesions suggestive of pre-cancer, of whom 8 (35%) had a same-day cold coagulation procedure, seven (30%) deferred cold coagulation to a later date (of whom 4 came for treatment), and 8 (35%) were referred to surgery due to size of lesion; 5/686 (0.7%) women had lesions suspicious of cancer. Conclusion: Incorporating cervical cancer screening into services at HIV clinics is feasible. A structured approach to screening in the HIV clinic was important.
