RESUMO

Objective: To identify which strain episodes are concurrently reported by several team members; to identify triggers of strain experienced by operating room (OR) team members during the intraoperative phase. Summary: OR teams are confronted with many sources of strain. However, most studies investigate strain on a general, rather than an event-based level, which does not allow to determine if strain episodes are experienced concurrently by different team members. Methods: We conducted an event-based, observational study, at an academic medical center in North America and included 113 operations performed in 5 surgical departments (general, vascular, pediatric, gynecology, and trauma/acute care). Strain episodes were assessed with a guided-recall method. Immediately after operations, participants mentally recalled the operation, described the strain episodes experienced and their content. Results: Based on 731 guided recalls, 461 strain episodes were reported; these refer to 312 unique strain episodes. Overall, 75% of strain episodes were experienced by a single team member only. Among different categories of unique strain episodes, those triggered by task complexity, issues with material, or others' behaviors were typically experienced by 1 team member only. However, acute patient issues (n = 167) and observations of others' strain (n = 12) (respectively, 58.5%; P < 0.001 and 83.3%; P < 0.001) were often experienced by 2 or more team members. Conclusions and relevance: OR team members are likely to experience strain alone, unless patient safety is at stake. This may jeopardize the building of a shared understanding among OR team members.

RESUMO

Systems of care have been established for obstetrics, trauma, and neonatology. An American College of Obstetricians and Gynecologists Presidential Task Force was established to develop a care system for gynecologic surgery. A group of experts who represent diverse perspectives in gynecologic practice proposed definitions of levels of gynecologic care using the Delphi method. The goal is to improve the quality of gynecologic surgical care performed in the United States by providing a framework of minimal institutional requirements for each level. Subgroups developed draft criteria for each level of care. The entire Task Force then met to reach consensus regarding the levels of care final definitions and parameters. The levels of gynecologic care framework focuses on systems of care by considering institutional resources and expertise, providing guidance on the provision of care in appropriate level facilities. These levels were defined by the ability to care for patients of increasing risk, complexity, and comorbidities, organizing gynecologic care around hospital capability. This framework can also be used to inform the escalation of care to appropriate facilities by identifying patients at risk and guiding them to facilities with the skills, expertise, and capabilities to safely and effectively meet their needs. The levels of gynecologic care framework is intended for use by patients, hospitals, and clinicians in the United States to guide where elective surgery can be done most safely and effectively by specialists and subspecialists in obstetrics and gynecology. The key features of the levels of gynecologic care include ensuring provision of risk-appropriate care and regionalization of care by facility capabilities.

RESUMO

The original vision of the field of gynecologic oncology was to establish a multidisciplinary approach to the management of patients with gynecologic cancers. Fifty years later, scientific advances have markedly changed the overall practice of gynecologic oncology, but the profession continues to struggle to define its value-financial and otherwise. These issues were examined in full at the Society of Gynecologic Oncology (SGO) Future of the Profession Summit and the purpose of this document is to summarize the discussion, share the group's perceived strengths, weaknesses, opportunities, and threats (SWOT) for gynecologic oncologists, further educate members and others within the patient care team about the unique role of gynecologic oncologists, and plan future steps in the short- and long- term to preserve the subspecialty's critical mission of providing comprehensive, longitudinal care for people with gynecologic cancers.

RESUMO

BACKGROUND: High-risk human papillomavirus (hrHPV) testing is utilized in primary cervical cancer screening, generally along with cytology, to triage abnormalities to colposcopy. Most screening-based hrHPV testing involves pooled detection of any hrHPV or of HPV16/18. Cervical neoplasia progression risks based on extended hrHPV genotyping-particularly non-16/18 hrHPV types-are not well characterized. HPV genotype-specific incidence of high-grade cervical intraepithelial neoplasia or more severe (CIN2+) following an abnormal screening result was examined. METHODS: We assessed a US-based prospective, multiracial, clinical cohort of 343 colposcopy patients with normal histology (n = 226) or CIN1 (n = 117). Baseline cervical samples underwent HPV DNA genotyping, and participants were followed up to 5 years. Genotype-specific CIN2+ incidence rates (IR) were estimated with accelerated failure time models. Five-year CIN2+ risks were estimated nonparametrically for hierarchical hrHPV risk groups (HPV16; else HPV18/45; else HPV31/33/35/52/58; else HPV39/51/56/59/68). RESULTS: At enrollment, median participant age was 30.1 years; most (63%) were hrHPV-positive. Over follow-up, 24 participants progressed to CIN2+ (7.0%). CIN2+ IR among hrHPV-positive participants was 3.4/1,000 person-months. CIN2+ IRs were highest for HPV16 (8.3), HPV33 (7.8), and HPV58 (4.9). Five-year CIN2+ risk was higher for HPV16 (0.34) compared with HPV18/45 (0.12), HPV31/33/35/52/58 (0.12), and HPV39/51/56/59/68 (0.16) (P = 0.05). CONCLUSIONS: Non-16/18 hrHPV types are associated with differential CIN2+ progression rates. HPV16, 33, and 58 exhibited the highest rates over 5 years. HPV risk groups warrant further investigation in diverse US populations. IMPACT: These novel data assessing extended HPV genotyping in a diverse clinical cohort can inform future directions to improve screening practices in the general population.

RESUMO

Uterine fibroids (leiomyomas), the most common benign tumors in women of reproductive age, are a frequent cause of abnormal vaginal bleeding and other reproductive complaints among women. This study investigates the feasibility of using histotripsy, a non-invasive, non-thermal focused ultrasound ablation method, to ablate uterine fibroids. Human fibroid samples (n = 16) were harvested after hysterectomy or myomectomy procedures at Carilion Memorial Hospital. Histotripsy was applied to ex vivo fibroids in two sets of experiments using a 700-kHz clinical transducer to apply multicycle histotripsy pulses and a prototype 500-kHz transducer to apply single-cycle histotripsy pulses. Ultrasound imaging was used for real-time treatment monitoring, and post-treatment ablation was quantified histologically using hematoxylin and eosin and Masson trichrome stains. Results revealed that multicycle histotripsy generated diffuse cavitation in targeted fibroids, with minimal cellular ablative changes after treatment with 2000 pulses/point. Single-cycle pulsing generated well-confined bubble clouds with evidence of early coagulative necrosis on histological assessment in samples treated with 2000 pulses/point, near-complete ablation in samples treated with 4000 pulses/point and complete tissue destruction in samples treated with 10,000 pulses/point. This study illustrates that histotripsy is capable of fibroid ablation under certain pulsing parameters and warrants further investigation as an improved non-invasive ablation method for the treatment of leiomyomas.

RESUMO

OBJECTIVES: To describe clinicopathologic characteristics and survival outcomes of endometrial adenocarcinomas stratified by mismatch repair (MMR) status. METHODS: Single-institution, retrospective study of all women with endometrioid adenocarcinomas treated from January 2012 through December 2017. Patients were categorized into one of three groups based on MMR testing: intact MMR expression (MMR+), probable MMR mutation (MMR-), or MLH1 hypermethylation (hMLH1+). Demographics, pathologic characteristics, recurrence rates, and survival differences were analyzed. RESULTS: In total, 316 women were included in the analysis: 235 (74.4%) patients in the MMR+ group, 10 (3.1%) in the MMR- group, and 71 (22.5%) in the hMLH1+ group. Patients with hMLH1+ were significantly older, exhibited higher-grade histology and presence of lymphovascular space invasion, and were more likely to have received adjuvant treatment. The early stage hMLH1+ patients were more likely to recur (15.3% hMLH1+ vs 2.3% MMR+ vs 12.5% MMR-, P < .001). Hypermethylation remained a significant predictor of recurrence in multivariable analysis (odds ratio, 5.09; 95% confidence interval [CI], 1.54-16.86; P = .008). Recurrence-free survival was significantly reduced in early stage hMLH1+ (hazard ratio, 7.40; 95% CI, 2.80-21.62; P < .001). CONCLUSIONS: Women with hMLH1+ endometrial cancer have worse prognostic features and recur more frequently, even in patients traditionally considered low risk for recurrence.

RESUMO

BACKGROUND: Epigenetic mechanisms are hypothesized to contribute substantially to the progression of cervical intraepithelial neoplasia (CIN) to cervical cancer, although empirical data are limited. METHODS: Women (n = 419) were enrolled at colposcopic evaluation at Duke Medical Center in Durham, North Carolina. Human papillomavirus (HPV) was genotyped by HPV linear array and CIN grade was ascertained by biopsy pathologic review. DNA methylation was measured at differentially methylated regions (DMRs) regulating genomic imprinting of the IGF2/H19, IGF2AS, MESTIT1/MEST, MEG3, PLAGL1/HYMAI, KvDMR and PEG10, PEG3 imprinted domains, using Sequenom-EpiTYPER assays. Logistic regression models were used to evaluate the associations between HPV infection, DMR methylation and CIN risk overall and by race. RESULTS: Of the 419 participants, 20 had CIN3+, 52 had CIN2, and 347 had ≤ CIN1 (CIN1 and negative histology). The median participant age was 28.6 (IQR:11.6) and 40% were African American. Overall, we found no statistically significant association between altered methylation in selected DMRs and CIN2+ compared to ≤CIN1. Similarly, there was no significant association between DMR methylation and CIN3+ compared to ≤CIN2. Restricting the outcome to CIN2+ cases that were HR-HPV positive and p16 staining positive, we found a significant association with PEG3 DMR methylation (OR: 1.56 95% CI: 1.03-2.36). CONCLUSIONS: While the small number of high-grade CIN cases limit inferences, our findings suggest an association between altered DNA methylation at regulatory regions of PEG3 and high grade CIN in high-risk HPV positive cases.

RESUMO

OBJECTIVE: To characterize trends in self-reported numbers and routes of hysterectomy for obstetrics and gynecology residents using the Accreditation Council for Graduate Medical Education (ACGME) case log database. METHODS: Hysterectomy case log data for obstetrics and gynecology residents completing training between 2002-2003 and 2017-2018 were abstracted from the ACGME database. Total numbers of hysterectomies and modes of approach (abdominal, laparoscopic, and vaginal) were compared using bivariate statistics, and trends over time were analyzed using simple linear regression. RESULTS: Hysterectomy data were collected from 18,982 obstetrics and gynecology residents in a median of 243 (interquartile range 241-246) ACGME-accredited programs. The number of graduating residents increased significantly over time (12.1/year, P<.001), whereas the number of residency programs decreased significantly (0.52 fewer programs per year, P<.001) over the 16-year period. For cases logged as "surgeon," the median number of abdominal hysterectomies decreased by 56.5% from 85 (interquartile range 69-102) to 37 (interquartile range 34-43) (P<.001). The median number of vaginal hysterectomies decreased by 35.5% from 31 (interquartile range 24-39) to 20 (interquartile range 17-25) (P=.002). The median total number of hysterectomies per resident decreased by 6.3% from 112 (interquartile range 97-132) to 105 (interquartile range 92-121) (P=.036). In contrast, the median number of laparoscopic hysterectomies increased by 115% from 20 (interquartile range 13-28) in 2008-2009 to 43 (interquartile range 32-56) in 2017-2018, despite the decrease in overall number of hysterectomies (P<.001). These trends were statistically significant. CONCLUSIONS: The total number of hysterectomies performed by obstetrics and gynecology residents in the United States is decreasing, and the routes are changing with decreases in abdominal and vaginal approaches, and an increase in use of laparoscopic hysterectomy.

RESUMO

BACKGROUND: Delivery of excellent patient care hinges on effective communication. Improved communication between physicians, patients, and colleagues can facilitate shared decision-making and foster successful interprofessional teams. Despite the importance of this skill, little is understood about the status or acceptability of dedicated communication training during obstetrics and gynecology (OB/GYN) residency. OBJECTIVE: To explore the national landscape of dedicated communication didactics during OB/GYN training. METHODS: Residents and program directors (PDs) at ACGME-accredited programs were emailed anonymized surveys. Survey responses pertaining to communication didactics and trainee experiences were evaluated using descriptive statistics and chi-squared tests. RESULTS: Of 143 PDs, 45 responded (31.5%). Although the total number of residents receiving our survey is unattainable, our 215 resident respondents can be estimated to represent at least 4.4% of trainees. 98.1% of residents reported challenging clinical communication at least monthly, with many reporting this weekly (47.9%) and daily (30.0%). A majority of PDs (77.8%) and residents (67.0%) endorsed interest in communication training. 62.2% of programs reported formally teaching communication skills. Certain topics were infrequently taught yet cited by residents as particularly challenging-such as "diffusing conflict" and "angry patient or family members." PDs tended to significantly overestimate trainee competence in conducting difficult conversations with both patients (p = 0.0003) and interdisciplinary colleagues (p < 0.0001), as compared with resident self-assessments. CONCLUSIONS: Residents encounter frequent challenging communications interactions, and often feel inadequately equipped to navigate them. Dedicated didactics may provide a critical component to optimally educating of the next generation of trainees within OB/GYN and more broadly.

RESUMO

OBJECTIVE: Enhanced Recovery After Surgery (ERAS) protocols are designed to mitigate the physiologic stress response created by surgery, to decrease the time to resumption of daily activities, and to improve overall recovery. This study aims to investigate postoperative recovery outcomes following gynecologic surgery before and after implementation of an ERAS protocol. METHODS: A retrospective chart review was performed of patients undergoing elective laparotomy at a major academic center following implementation of an ERAS protocol (11/4/2014-7/27/2016) with comparison to a historical cohort (6/23/2013-9/30/2014). The primary outcome was length of hospital stay. Secondary outcomes included surgical variables, time to recovery of baseline function, opioid usage, pain scores, and complication rates. Statistical analyses were performed using Wilcoxon rank sum, Fisher's exact, and chi squared tests. RESULTS: One hundred and thirty-three women on the ERAS protocol who underwent elective laparotomy were compared with 121 historical controls. There was no difference in length of stay between cohorts (median 4 days; P = 0.71). ERAS participants had lower intraoperative (45 vs 75 oral morphine equivalents; P < 0.0001) and postoperative (45 vs 154 oral morphine equivalents; P < 0.0001) opioid use. ERAS patients reported lower maximum pain scores in the post-anesthesia care unit (three vs six; P < 0.0001) and on postoperative day 1 (four vs six; P = 0.002). There was no statistically significant difference in complication or readmission rates. CONCLUSIONS: ERAS protocol implementation was associated with decreased intraoperative and postoperative opioid use and improved pain scores without significant changes in length of stay or complication rates.

RESUMO

OBJECTIVE: Endocrine therapy is often considered as a treatment for hormone-responsive gynecologic malignancies. In breast cancer, activating mutations in the estrogen receptor (mutESR1) contribute to therapeutic resistance to endocrine therapy, especially aromatase inhibitors (AIs). The purpose of this study was to evaluate the frequency and clinical relevance of ESR1 genomic alterations in gynecologic malignancies. METHODS: DNA from FFPE tumor tissue obtained during routine clinical care for 9645 gynecologic malignancies (ovary, fallopian tube, uterus, cervix, vagina, vulvar, and placenta) was analyzed for all classes of genomic alterations (base substitutions (muts), insertions, deletions, rearrangements, and amplifications) in ESR1 by hybrid capture next generation sequencing. A subset of alterations was characterized in laboratory-based transcription assays for response to endocrine therapies. RESULTS: A total of 295 ESR1 genomic alterations were identified in 285 (3.0%) cases. mutESR1 were present in 86 (0.9%) cases and were more common in uterine compared to other cancers (2.0% vs <1%, respectively p < 0.001). mutESR1 were enriched in carcinomas with endometrioid versus serous histology (4.4% vs 0.2% respectively, p < 0.0001 in uterine and 3.5% vs 0.3% respectively, p = 0.0004 in ovarian carcinomas). In three of four patients with serial sampling, mutESR1 emerged under the selective pressure of AI therapy. Despite decreased potency of estrogen receptor (ER) antagonists in transcriptional assays, clinical benefit was observed following treatment with selective ER-targeted therapy, in one case lasting >48 months. CONCLUSIONS: While the prevalence of ESR1 mutations in gynecologic malignancies is low, there are significant clinical implications useful in guiding therapeutic approaches for these cancers.

RESUMO

OBJECTIVE: The primary aim of this study was to pilot the use of an objective measurement technique to prospectively evaluate the incidence of lower extremity lymphedema (LEL) after minimally invasive staging surgery for endometrial cancer. Secondary objectives included observation of changes in lower extremity function and quality of life in this patient population. METHODS: A prospective evaluation of LEL was performed in 97 women who underwent minimally invasive staging surgery for endometrial cancer using comparative circumferential volume measurements. Postoperative changes in lower extremity function and global quality of life were also assessed using patient-reported outcome measures. RESULTS: Ninety-seven patients were included for lymphedema analysis. The rate of LEL was 25% at 4-6 weeks, 19% at 6-9 months, and 27% at 12-18 months postoperatively. The presence of LEL was associated with a significant worsening from baseline Lower Extremity Functional Scale (LEFS) scores at 4-6 weeks (-27.0% vs -3.7%, p = 0.02) and 6-9 months (-13.0% vs 0%, p = 0.01). LEL was not associated with a change in patient-reported global quality of life. CONCLUSIONS: Up to one in four women experience lymphedema following surgical staging for endometrial cancer, and its presence is associated with diminished lower extremity function. Larger, prospective trials using the objective methodology piloted in this study should better clarify risk factors and long-term outcomes of this morbidity.

RESUMO

The role of host epigenetic mechanisms in the natural history of low-grade cervical intraepithelial neoplasia (CIN1) is not well characterized. We explored differential methylation of imprinted gene regulatory regions as predictors of the risk of CIN1 regression. A total of 164 patients with CIN1 were recruited from 10 Duke University clinics for the CIN Cohort Study. Participants had colposcopies at enrollment and up to five follow-up visits over 3 years. DNA was extracted from exfoliated cervical cells for methylation quantitation at CpG (cytosine-phosphate-guanine) sites and human papillomavirus (HPV) genotyping. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated using Cox regression to quantify the effect of methylation on CIN1 regression over two consecutive visits, compared to non-regression (persistent CIN1; progression to CIN2+; or CIN1 regression at a single time-point), adjusting for age, race, high-risk HPV (hrHPV), parity, oral contraceptive and smoking status. Median participant age was 26.6 years (range: 21.0-64.4 years), 39% were African-American, and 11% were current smokers. Most participants were hrHPV-positive at enrollment (80.5%). Over one-third of cases regressed (n = 53, 35.1%). Median time-to-regression was 12.6 months (range: 4.5-24.0 months). Probability of CIN1 regression was negatively correlated with methylation at IGF2AS CpG 5 (HR = 0.41; 95% CI = 0.23-0.77) and PEG10 DMR (HR = 0.80; 95% CI = 0.65-0.98). Altered methylation of imprinted IGF2AS and PEG10 DMRs may play a role in the natural history of CIN1. If confirmed in larger studies, further research on imprinted gene DMR methylation is warranted to determine its efficacy as a biomarker for cervical cancer screening.

RESUMO

To determine whether the processing of additional adipose tissue collected during lymph node (LN) dissection results in the identification of additional LNs during endometrial cancer (EC) staging and to determine if the division of LNs into nodal basin-specific specimens has an effect on the number of LNs identified during EC staging. A prospective randomized controlled trial was performed on women with high-grade EC undergoing surgical staging. Subjects were randomized to collection of LNs into nodal basin-specific containers on the randomized side versus simple labeling on the nonrandomized side. The total number of LNs and total number of LNs with metastases on the randomized versus the nonrandomized side were compared. The remaining adipose tissue from each LN specimen was submitted for histologic examination. We analyzed the number of LNs with and without metastases identified from additional adipose tissue. Of 120 consented subjects, 56 had sufficient data for analysis. The additional adipose tissue contained 7.5 additional LNs per patient on average (range: 0-26). In 2/54 total cases (3.7%) and 2/5 cases with nodal metastases (40%), the additional adipose contained LNs with metastases. In both cases, metastases were also detected in grossly identified LN candidates. The mean number of LNs identified was not significantly different based on method of collection (P=0.22). The mean number of LNs containing metastases per side was not significantly different (P=0.58). Processing of adipose tissue does increase the total number of LNs identified, however, it does not influence EC stage. No difference in LN counts was noted with basin-specific collection.

RESUMO

Vulvar cancer is a rare gynecologic malignancy. Ninety percent of vulvar cancers are predominantly squamous cell carcinomas (SCCs), which can arise through human papilloma virus (HPV)-dependent and HPV-independent pathways. The NCCN Vulvar Cancer panel is an interdisciplinary group of representatives from NCCN Member Institutions consisting of specialists in gynecological oncology, medical oncology, radiation oncology, and pathology. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Vulvar Cancer provide an evidence- and consensus-based approach for the management of patients with vulvar SCC. This manuscript discusses the recommendations outlined in the NCCN Guidelines for diagnosis, staging, treatment, and follow-up.

RESUMO

OBJECTIVE: To determine the rate and performance of sentinel lymph node (SLN) mapping among women with high-risk endometrial cancers. METHODS: Patients diagnosed between 2012 and 2015 with uterine cancer of grade 3 endometrioid, clear cell, serous or carcinosarcoma histology and who underwent SLN mapping prior to full pelvic lymph node dissection were included. Subjects underwent methylene blue or ICG injection for laparoscopic (N = 16) or robotic-assisted laparoscopic (N = 20) staging. Outcomes included SLN mapping rates, SLN and non-SLN positive rates, false negative SLN algorithm rate, and the negative predictive value (NPV) of the SLN algorithm. Fisher's exact test was used to compare mapping and node positivity rates. RESULTS: 9/36 (25%) patients with high-risk uterine cancer had at least one metastatic lymph node identified. Successful mapping occurred in 30/36 (83%) patients. SLN mapped to pelvic nodes bilaterally in 20 (56%), unilaterally in 9 (25%), and aortic nodes only in 1 (3%). Malignancy was identified in 14/95 (15%) of all sentinel nodes and 12/775 (1.5%) of all non-sentinel nodes (p < 0.001). The false negative rate of SLN mapping alone was 2/26 (7.7%); the NPV was 92.3%. When the SLN algorithm was applied retrospectively the false negative rate was 0/31 (0%); the NPV was 100%. CONCLUSION: SLN mapping rates for high-risk cancers are slightly lower than in prior reports of lower risk cancers. The NPV of the SLN mapping alone is 92% and rises to 100% when the SLN algorithm is applied. Such results are acceptable and consistent with larger subsets of lower risk endometrial cancers.

RESUMO

BACKGROUND AND OBJECTIVE: Over the past 10years, robotic surgery has revolutionized the advancement of MIS in gynecologic oncology. As the use of robotic surgery has increased, so has the interest in the surgical training of gynecologic oncology fellows. The purpose of this review is to summarize the state of robotic surgical education in Gynecologic Oncology. METHODS: Several electronic databases were searched to identify studies that discussed robotic surgical education in gynecologic oncology. Particular attention was given to articles that discussed educational curriculum. The various curriculums were compared and summarized. RESULTS: The first reports of robotic surgery curriculums in gynecologic oncology emerged in 2008. Prior to that the early adapters had to rely on less structured curriculums that essentially used live animal models and cadaveric dissections on the robot to simulate live surgery. More recent surgical curriculums are more structured and include the same basic components: didactics and a graduated hands-on experience. There is also an accredited robotic educational curriculum, the Fundamentals of Robotic Surgery (FRS), which combine an on-line curriculum with dry lab and operating room components that can be scored using a validated assessment tool. CONCLUSIONS: Robotic surgical education has come a long way in the decade that the robotic platform has been available in the U.S. Although there is still no standardized curriculum, most fellowship training programs in gynecologic oncology have fairly consistent training. Simulation training is another tool that can help a surgeon achieve proficiency quicker.
