RESUMO

With the rising need for accessible cervical cancer screening, self-sampling methods offer a promising alternative to traditional physician-led sampling. This study aims to evaluate the efficacy of the HygeiaTouch Self Sampling Kit for Women in detecting human papillomavirus (HPV) types and predicting cervical lesions. We studied the concordance in identifying high-risk HPV (hrHPV) types between samples collected by physicians and those self-collected by women using a self-sampling kit for validation. Women aged 21-65, fitting into specific categories based on their cervical health history were eligible. Cohen's kappa coefficient to gauge concordance between the two specimen types and relative accuracy metrics in identifying cervical intraepithelial neoplasia (CIN) were also calculated, with physician-sampled specimens serving as a reference. A total of 1210 participants from three institutes were involved. The self-sampling kit closely matched the physician-led method in terms of collecting valid specimens (100% vs. 100%), identifying hrHPV types (kappa: 0.75, 95% confidence interval [95% CI]: 0.72-0.79; agreement: 87.7%, 95% CI: 85.8-89.6) and predicting CIN grade 2 or worse (CIN2+) (relative sensitivity: 0.949, relative accuracy: 0.959). Kappa values varied between 0.71 and 0.83 for different hrHPV types and combinations, with an overall value 0.75 (95% CI: 0.72-0.79) signifying robust compatibility between the two methods. Our study underscores the potential of the HygeiaTouch Self Sampling Kit as a reliable, efficient, and user-friendly alternative to traditional sampling methods. This suggests that self-sampling could be pivotal in expanding cervical cancer screening accessibility and enhancing detection rates.

RESUMO

Steroid cell tumors, not otherwise specified (SCT-NOS), are uncommon ovarian neoplasms accompanied by virilization symptoms due to hyperandrogenism, which are malignant in approximately one-third of the cases. Given the rarity of SCT-NOS, their molecular underpinnings have not yet been studied in depth. In this case series, we performed the first comprehensive analysis of the genetic landscape of this rare ovarian tumor. A detailed clinicopathological description of an index case is also provided. Over a 20-year period, a total of eight patients were seen at our institution. Total nucleic acids (RNA and DNA) were extracted from evaluable formalin-fixed, paraffin-embedded tumor specimens (n = 7) and subjected to TruSight Oncology 500 testing and/or exome sequencing. The results identified pathogenic variants in several hypoxia-related genes - including HIF1A, VHL, SDHB, SRC, IDH2, and FOXO4. As the first comprehensive genetic analysis of SCT-NOS, this study shows that dysregulation in the hypoxia signaling pathway is a key molecular feature of this rare tumor. Clinically, long-term follow-up with periodic measurements of androgen levels should be pursued in all cases since recurrences may occur several years after the initial diagnosis.

RESUMO

OBJECTIVE: To evaluate the regression rate of endometrial polyps (EPs) in a cohort of asymmetric women after conservative follow-up. MATERIALS AND METHODS: In this retrospective cohort study, a total of 1006 women with asymptomatic EPs were treated with expectant management or hormonal drugs between June 1999 and May 2018. Four hundred forty-eight women (44.5%) were administered with hormonal medications and 558 women were managed expectantly (55.5%). Office hysteroscopy was performed to confirm the diagnosis and regression of EPs. Hormonal administration included oral contraceptives, progestin and cyclic estrogen/progestin regimen according to physicians' preferences. Clinical characteristics, including the patient's age, body mass index, parity, and type of conservative management were collected. RESULTS: The mean observation time was 14.1 ± 18.5 months (range, 1-162 months). The overall regression rate of EPs in this cohort was 33.5%, 24.6% occurred after medication and 8.9% after expectant management. Patient age (<50 years) (p < 0.001), follow-up period (p = 0.005) and hormonal drugs used (p < 0.001) were significantly associated with EP regression. Twenty-four (7.1%) of the 337 EP regression patients later developed recurrent disease. Follow-up period (p < 0.001) and hormonal drugs used (p = 0.032) were closely related to polyp recurrence after initial regression. Nevertheless, multivariate logistic regression analysis revealed that hormonal drugs used was significantly associated with the regression (p < 0.001) and recurrence (p = 0.016) of EPs. CONCLUSION: Women aged 50 or less are more suitable for conservative treatment for EPs. Hormonal drugs used could increase the incidence of EP regression.

RESUMO

The pathogenic influences of uterine bacteria on endometrial carcinogenesis remain unclear. The aim of this pilot study was to compare the microbiota composition of endometrial lavage samples obtained from women with either endometrial hyperplasia (EH) or endometrial cancer (EC) versus those with benign uterine conditions. We hypothesized that specific microbiota signatures would distinguish between the two groups, possibly leading to the identification of bacterial species associated with endometrial tumorigenesis. A total of 35 endometrial lavage specimens (EH, n = 18; EC, n = 7; metastatic EC, n = 2; benign endometrial lesions, n = 8) were collected from 32 women who had undergone office hysteroscopy. Microbiota composition was determined by sequencing the V3-V4 region of 16S rRNA genes and results were validated by real-time qPCR in 46 patients with EC/EH and 13 control women. Surprisingly, we found that Bacillus pseudofirmus and Stenotrophomonas rhizophila - two plastic-degrading bacterial species - were over-represented in endometrial lavage specimens collected from patients with EC/EH. Using computational analysis, we found that the functional profile of endometrial microbiota in EC/EH was associated with fatty acid and amino acid metabolism. In summary, our hypothesis-generating data indicate that the plastic-degrading bacteria Bacillus pseudofirmus and Stenotrophomonas rhizophila are over-represented within the endometrial lavage microbiota of women with EC/EH living in Taiwan. Whether this may be related to plastic pollution deserves further investigation.

RESUMO

We aimed to detect endometrial cancer (EC)-associated mutations in endometrial lavage specimens collected in an office setting and to compare the detected mutations with those identified in tissue samples. Participants included 16 women attending for an office hysteroscopy because of suspected EC between July 2020 and October 2021. Massively parallel sequencing was conducted using the targeted 72 cancer-associated genes. Endometrial lavage specimens, endometrial tissue samples, and blood samples were simultaneously sequenced to establish the concordance of genetic alterations. In this study, the vast majority of EC-associated mutations identified in lavage samples (R2 = 0.948) were identical to those detected in endometrial tissues. Of the 13 patients with EC, 12 (92.3%) had at least one mutation identified in endometrial lavage samples. Notably, no mutations in lavage samples were identified in the two patients with a previous history of EC but no actual endometrial lesions, supporting a high negative predictive value of the test. A patient previously diagnosed with EC and with current evidence of atypical hyperplasia showed persisting PTEN, PIK3R1, and KRAS mutations in her endometrial lavage specimen. PTEN was the most commonly mutated gene, followed by PIK3R1, ARID1A, PIK3CA, CTNNB1, and KRAS. In conclusions, our study provides pilot evidence on the actionability of uterine lavage samples sequencing to detect EC-associated mutations in women with suspected endometrial lesions. In a precision medicine framework, the high mutational concordance between uterine lavage samples and tissue specimens may help inform less invasive diagnostic protocols and the need for ongoing surveillance in patients with EC who wished for fertility-preserving treatment. KEY MESSAGES: • Sequencing of uterine lavage samples collected by office hysteroscopy is feasible. • Most EC mutations identified in lavage were identical to endometrial tissues. • Sequencing of uterine lavage samples may help inform diagnostic protocols for EC. • This approach can be used for recurrence surveillance in patients with EC.

RESUMO

Background: Endometrial hyperplasia (EH), particularly with atypia, is considered an antecedent of endometrial adenocarcinoma. In this study, we aimed to apply massively parallel sequencing of endometrial lavage specimens for the detection of cancer-associated mutations in atypical (AEH) and non-atypical endometrial hyperplasia (NEH). The identified alterations were compared with those detected in tissue samples. Materials and methods: Endometrial lavage specimens and parallel biopsy samples (n = 11 for AEH and n = 9 for NEH) were obtained from 18 women (9 with AEH and 9 with NEH) who received an office hysteroscopy for suspected endometrial lesions. All samples were tested for somatic mutations in hotspot regions of 72 cancer-associated genes by massively parallel sequencing. Results: On analyzing sequencing data, the presence of at least one cancer-associated gene mutation was identified in 72.7 and 44.4% of endometrial lavage specimens obtained from women with AEH and NEH, respectively (p = 0.362, 95% confidence interval = 0.72-3.70). The concordance rates between mutations identified in endometrial lavage specimens and endometrial biopsies were 54.5 and 0% from women with AEH and NEH, respectively (p = 0.014). A patient with NEH harbored mutations in endometrial lavage with the same mutations found in the tissue specimen at low allele frequency below detection cutoff, raising the suspicion of missed focal atypia. Conclusion: Endometrial hyperplasia is characterized by a high burden of cancer-associated mutations, particularly in the presence of atypia. Our study, albeit performed with a relatively small number of samples, indicates that their detection by massively parallel sequencing of endometrial lavage is feasible. Our findings may allow tailoring of endometrial biopsies to the individual risk of AEH; additionally, they can pave the way toward less invasive surveillance protocols in patients with known EH.

RESUMO

PURPOSE: Uterine fibroids are benign gynecologic tumors and commonly occur in women by the age of 50. Women with symptomatic uterine fibroids generally receive surgical intervention, while they do not favor the invasive therapies. To evaluate the feasibility and safety of a novel magnetic resonance-guided high-intensity focused ultrasound (MRgHIFU) modality, ArcBlate, in the treatment of uterine fibroids. METHODS: Nine patients with uterine fibroids and one patient with adenomyosis were treated with ArcBlate MRgHIFU. Tumor size and quality of life were evaluated postoperatively at 1 and 3 months by magnetic resonance imaging (MRI) and the 36-Item Short Form Survey (SF-36), respectively. RESULTS: All patients completed the ArcBlate MRgHIFU procedure and there were no treatment-related adverse effects either during the procedure or during the 3 months of follow-up. Despite limiting the ablation volume to under 50% of the treated fibroid volume as a safety precaution, tumor volumes were markedly reduced in four patients by 15.78-58.87% at 3-month post-treatment. Moreover, SF-36 scale scores had improved at 3 months from baseline by 2-8 points in six patients, indicating relief of symptoms and improved quality of life. CONCLUSION: This study evidence demonstrates the safety and feasibility of ArcBlate MRgHIFU and suggests its potential for treating uterine fibroids.

RESUMO

BACKGROUND: To evaluate the use of a human fibrin glue (Tisseel) for minor bleeding control and approximation of ovarian defect during transvaginal natural orifice ovarian cystectomy (TNOOC) of benign and non-endometriotic ovarian tumors. METHODS: A total of 125 women with benign and non-endometriotic ovarian tumors who underwent TNOOC between May 2011 and January 2020: 54 with the aid of Tisseel and 71 with traditional suture for hemostasis and approximation of ovarian defect. Surgical outcomes such as length of surgery, operative blood loss, postoperative pain score, and postoperative hospital stay were recorded. Before and immediately (10 days) and at 6 months after the procedure, serum anti-Müllerian hormone (AMH) levels were also determined. RESULTS: Complete hemostasis and approximation of ovarian defect were achieved in all cases. No significant difference was noted in the operating time, operative blood loss, postoperative pain scores after 12, 24 and 48 h, length of postoperative stay, and baseline AMH levels between the two groups. The operation did not have a negative effect on the immediate and 6-month postoperative AMH levels in the suture group. However, the decline in the AMH levels was significant immediately after surgery in the Tisseel group, nevertheless, no significant difference was noted in the AMH levels at 6 months (3.3 vs. 1.7 mg/mL; p = 0.042, adjusted p = 0.210). CONCLUSION: The use of Tisseel in TNOOC of benign and non-endometriotic ovarian tumors without suturing the ovarian tissue is clinically safe and feasible.

RESUMO

BACKGROUND: Extracellular and cell-surface molecules remain the most common druggable cancer targets. However, intracellular therapeutic modalities are gaining momentum. The overexpression of stress-induced phosphoprotein 1 (STIP1), an adaptor protein that coordinates the functions of different chaperones in protein folding, has been reported in several solid malignancies. Here, we investigated the effects of intracellular STIP1 inhibition, attained either through the HEPES-mediated cytosolic delivery of anti-STIP1 antibodies or the use of a cell-penetrating signal-tagged peptide 520, in different human cancer cell lines and luciferase-expressing murine ovarian cancer cells (MOSEC/Luc) tumor-bearing C57BL/6 mice. METHODS: The effects of STIP1 in different human cell lines were determined by cell viability, cell cytotoxicity and cell apoptosis assays. Immunoblotting was used to assess the relevant proteins found in this study and tumor xenograft mice models were also employed. RESULTS: Intracellular targeting of STIP1 inhibited cancer cell line growth and promoted caspase 3-dependent apoptotic cell death. Moreover, the intracellular delivery of anti-STIP1 antibodies facilitated the degradation of STIP1 and two of its client proteins, lysine-specific demethylase 1 and Janus kinase 2. In vivo studies demonstrated that survival of mice bearing experimental tumors was improved by administration of anti-STIP1 antibodies. CONCLUSIONS: Our findings demonstrate that the cytosolic inhibition of STIP1 in tumor cells is feasible and provides a solid basis for further investigation of STIP1 as an intracellular cancer target. Our findings demonstrate that cytosolic inhibition of STIP1 in tumor cells is feasible and provide a solid basis for further exploration of STIP1 as an intracellular cancer target.

RESUMO

This study was designed to evaluate the learning curve of applying Seprafilm (modified hyaluronic acid and carboxymethylcellulose; Genzyme, Cambridge, MA, USA) during laparoscopic hysterectomy or subtotal hysterectomy with or without adnexectomy. In this retrospective cohort study, 35 patients who underwent laparoscopic hysterectomy or subtotal hysterectomy with or without adnexectomy were enrolled. The Seprafilm was cut into 4 pieces, rolled up with a trimmed plastic sleeve and delivered through an incision wound made for the 5-mm ancillary trocar. The membrane was unrolled and placed on the rough surface after hysterectomy or subtotal hysterectomy with or without adnexectomy. The time from the insertion of the first piece of membrane into the abdominal cavity to the complete removal of the trimmed plastic sleeve was recorded. The median time for Seprafilm placement was 3 min. The learning curve was analyzed using the power-law method and suggested that 10 cases were required to achieve proficiency in the procedure. The presence of adnexectomy was significantly associated with the time required for Seprafilm placement (P < 0.001). Although Seprafilm placement is more complicated compared to the liquid and gel forms of anti-adhesion barriers, surgical proficiency seemed to be attained after 10 cases for an experienced surgeon.

RESUMO

OBJECTIVE: To demonstrate an innovative idea for a four-petal method for performing laparoscopic adenomyomectomy on a patient with focal-type adenomyosis. DESIGN: A step-by-step explanation of the technique with narrated video footage. SETTING: University hospital. PATIENT(S): A 38-year-old female with a 7 × 4 cm adenomyoma at the anterior uterine wall. INTERVENTION(S): Laparoscopic adenomyomectomy began with a cruciate incision to turn the adenomyoma into the shape of a blooming four-petal flower to fully expose the tumor and maximize the removal of adenomyotic tissue. During excision of the lesion, around a 1 cm thickness of the myometrium was preserved at the subendometrial region and around a 0.5 cm thickness of the serosa flap was also left in each "petal." Suture repair in the method introduced is different from closing the wound by approximation of myometrium to myometrium as in traditional myomectomy; instead, herein we repaired the adenomyomectomy wound by anchoring the serosal flap to the subendometrial tissue, with care taken to avoid dead space. MAIN OUTCOME MEASURE(S): Subjective clinical symptoms as well as serial ultrasonographic measurement of the uterine size, shape, and wall thickness. RESULT(S): The specimen removed was 92 g in weight. The symptoms have dramatically decreased since the procedure and dysmenorrhea improved from visual analog scale 8 to 1 postoperatively. Besides achieving satisfactory symptomatic relief, the ultrasonographic measurement of the myometrium was of adequate thickness (2.3 cm) after the operation and did not increase in a serial follow-up of 33 months. CONCLUSION(S): The four-petal method of adenomyomectomy with cruciate incision offers full exposure to the localized adenomyosis. It greatly facilitates a balance between the maximized resection of the lesions and tailored reserves of myometrium. Subsequent repair by anchoring the serosal flap to the subendometrial tissue ensures adequate thickness of the uterine wall after the operation.

RESUMO

STUDY OBJECTIVE: This study was designed to evaluate the learning curve of transvaginal natural orifice surgery (NOS) for adnexal tumors based on the type of procedure (adnexectomy or cystectomy). DESIGN: Retrospective cohort study. SETTING: Tertiary-care university hospital. PATIENTS: One hundred thirty-six women with adnexal tumors. INTERVENTIONS: A series of 136 consecutive transvaginal NOS for adnexal tumor were performed between April 2011 and June 2016. Eighty-five patients (62.5%) had undergone cystectomy, and 51 patients (37.5%) had undergone adnexectomy. MEASUREMENTS AND MAIN RESULTS: The transvaginal NOS procedures included vaginal, endoscopic, single-port access techniques and were divided into 2 categories: adnexectomy and cystectomy. Operating time was electronically recorded and was defined as the time from the creation of a posterior colpotomy incision until the complete closure of the posterior colpotomy opening. The average operating time for the cystectomy and adnexectomy groups was 42.7 and 37.7 minutes, respectively (p = .015). The learning curve was analyzed using the cumulative summation method and showed that 36 cases were needed to achieve proficiency in transvaginal NOS for ovarian cystectomy. However, there was no significant cut-off point to determine the number of patients who had undergone adnexectomy. CONCLUSION: A well-trained gynecologic endoscopist can achieve surgical proficiency in transvaginal NOS cystectomy after 36 cases. It is suggested that the surgical transvaginal NOS procedure should begin with adnexectomy rather than with cystectomy to avoid initial technical challenges.

RESUMO

This report describes a simple technique using conventional instrumentation for the placement of Seprafilm, a sodium hyaluronate or carboxymethylcellulose absorbable barrier for adhesion prevention. A total of 378 women with uterine myomas undergoing laparoscopic myomectomies had 737 Seprafilm pieces placed. Seprafilm sheet was softened through exposure to room air for 5 minutes, cut into 4 pieces (length, 5-10 mm), rolled up alongside a plastic sheet cut from a camera drape cover, and gently placed at the right paracolic gutter. The Seprafilm pieces unfolded semiautomatically on release and were then placed on the uterus. The median time to apply per Seprafilm piece was 1 (range: 0.8-3.5) minute. We failed to place 16 pieces (16 of 737, 2.2%) in 11 patients. Virginal status, myoma weight, and the number of removed myomas were the risk factors of failed placement. Our technique for Seprafilm placement during laparoscopic myomectomy is simple and safe.

RESUMO

BACKGROUND: To evaluate the feasibility and applicability of using office hysteroscopy in women with intact hymen. METHODS: We recruited 836 patients with intact hymen with different indications who underwent diagnostic hysteroscopy without anesthesia in an outpatient setting from 2007 to 2016 at Chang Gung Memorial Hospital at Linkou. RESULTS: Patients' mean age was 35 ± 10.6 years (range 3-69 years). Most patients (86.4%) with postmenopausal bleeding had intrauterine lesions, and they were especially at high risk (50%) for endometrial hyperplasia or malignancy. Five hundred thirty (63.3%) patients had histologic findings confirming concordance between hysteroscopic and histologic findings. Submucosal myoma had the highest concordance (96.3%), whereas endometrial hyperplasia had the lowest concordance (50%). Forty-eight patients (5.7%) had endometrial hyperplasia, and 35 patients (4.2%) had endometrial malignancy. Two patients who were thought to have nonspecific endometrial thickening actually had endometrial pathology. CONCLUSIONS: Hysteroscopy through vaginoscopic approach is feasible and well-tolerated in the patients with intact hymen. This outpatient procedure provides accurate evaluation of lesions of the genital tract and should be considered in patients without a history of intercourse.

RESUMO

BACKGROUND: No data are available to assess the learning curve for transvaginal natural orifice transluminal endoscopic hysterectomy for non-prolapsed uteri in benign gynecologic diseases. The lack of exposure to transvaginal natural orifice transluminal endoscopic hysterectomy during training, in addition to a poorly defined learning curve, further deters interested physicians from applying this technique to daily practice. The aim of this study was to evaluate the learning curve and perioperative outcome of transvaginal natural orifice transluminal endoscopic hysterectomy by an experienced endoscopist. METHODS: A total of 240 cases of transvaginal natural orifice transluminal endoscopic hysterectomies with or without adnexectomy for various benign gynecologic diseases were included. Demographic data and various perioperative parameters were reviewed from the prospectively collected database. Operative time was set as a surrogate marker for surgical competency. The learning curve was evaluated using the cumulative sum method. RESULTS: The overall mean operative time (OT) was 76.5 min ± 22.4. Four unique phases of the learning curve were derived using cumulative sum analysis: the mean OT of phase I (the initial learning curve of 20 cases) was 86.3 ± 23.7 min, phase II (acquisition of competence of 80 cases) was 71.0 ± 21.4 min, phase III (proficiency and plateau of 80 cases) was 76.0 ± 20.4 min, and phase IV (post-learning in which more challenging cases were managed) was 81.3 ± 23.6 min. No major complications were encountered. One case in phase III converted to laparoscopy due to difficulty in performing anterior colpotomy. CONCLUSION: Our data demonstrated four distinct phases of the learning curve of transvaginal natural orifice transluminal endoscopic hysterectomy. In a well-trained endoscopist, surgical competence in transvaginal natural orifice transluminal endoscopic hysterectomy can be reached after 20 cases.

RESUMO

OBJECTIVE: To evaluate the efficacy and effectiveness of applying LigaSure™ Tissue Fusion System in hysterectomy via transvaginal natural orifice transluminal endoscopic surgery (NOTES) in comparison with using the conventional bipolar device. MATERIALS AND METHODS: Eighty women scheduled for hysterectomy by transvaginal NOTES were prospectively randomized into applying LigaSure (study group) or conventional bipolar instrument (control group) in an intention-to-treat analysis. Primary endpoints were the device-related efficacy; secondary endpoints were surgical effectiveness measured by operative time, blood loss, postoperative pain and adverse events. RESULTS: In the eligibly allocated patients, three in the control group (n = 39) converted to applying LigaSure and one converted to conventional laparoscopy intraoperatively, while none in the LigaSure group (n = 38) found such conversions. Patients who completed full analysis in the LigaSure (n = 36) and control (n = 35) groups did not differ significantly in operative time, estimated blood loss, and the length of hospital stay. In the subgroup of women who underwent hysterectomy only, the LigaSure group (n = 22) showed significantly reduced operative time than the control group (76.50 ± 24.74 min versus 93.96 ± 27.10 min, p = 0.029). Postoperative pain scores were statistically higher in the LigaSure group within 36 h; however, the difference was not clinically significant. The incidence of postoperative adverse events between the groups was not different; nevertheless, device-related adverse events was not found in the LigaSure group. CONCLUSION: LigaSure™ tissue fusion technology was feasible and efficacious without compromising surgical procedures for hysterectomy by transvaginal NOTES compared with the conventional bipolar hemostasis device.

RESUMO

STUDY OBJECTIVE: To study the outcome of a novel method of laparoscopic neovaginal reconstruction using rudimentary uterine horn serosa and the pelvic peritoneum as a graft. DESIGN: Canadian Task Force classification II-1. SETTING: A university hospital. PATIENTS: A retrospective study of 14 patients from 2000 to 2014 of patients with vaginal agenesis who underwent laparoscopic neovagina reconstruction using rudimentary uterine horn serosa and the pelvic peritoneum as a graft. INTERVENTION: Patients with vaginal agenesis associated with müllerian agenesis who requested surgery. Tertiary referral center and laparoscopic unit. The creation of a neovagina using rudimentary uterine horn serosa and the pelvic peritoneum as a graft via a combined laparoscopic and vaginal route. MEASUREMENTS AND MAIN RESULTS: Data were collected retrospectively including postoperative vaginal length and width, complications, stenosis or reoperations, dyspareunia, and sexual satisfaction. There were no major complications from the surgery with no rectal perforation or bladder or ureteric injury. The postoperative mean (±SD) vaginal length was 6.0±0.7 cm and a width of 2 fingerbreadths. The mean operation time was 142.7±45.9 min. Median blood loss was 100 ml (range: 10 to 300 mL). The mean duration of the hospital stay was 6.6±1.6 days. The follow-up period ranged from 3 to 84 months with a median follow-up of 11 months. CONCLUSION: Lee's method of neovaginoplasty using rudimentary uterine horn serosa and the pelvic peritoneum as a graft is a good method for neovagina creation with minimal morbidity, fast recovery, and minimal complications. This method results in good anatomic and functional outcome and can be a method that is widely used.
