RESUMEN

OBJECTIVE: Distribution of cervical dysplasia may influence approach for excisional procedures. Separating colposcopy biopsies into multiple specimen cups for pathologic evaluation incurs additional costs. The authors aimed to determine whether the practice of separating biopsy specimens impacts patient outcomes. METHODS: A retrospective review of all colposcopy cases from a single institution was performed. A total of 1,331 cases were reviewed from January 1, 2017, to December 31, 2019. Multibiopsy cohorts were separated by number of specimen cups received by pathology (single or multiple). Cohorts were compared for histology, need for excisional procedure, and final excisional pathology results. Specimen processing fees were acquired from the Department of Pathology ($70/specimen). Statistical analysis performed on MINITAB using Pearson chi-square and Fisher exact tests. RESULTS: Excisional procedures were required by 30.4% (86/283) of multiple specimen submissions compared with 28.2% (154/547) of single specimen cup submissions ( p = .50). There was a higher, although not statistically significant, rate of additional procedures in the multiple specimen cup cohort (8.8 vs 2.9% [ p = .08]). Malignancy diagnosis was equivalent in each cohort. Cost analysis revealed adopting a single specimen cup model would reduce costs up to approximately $30,000/year. CONCLUSIONS: Patient outcomes were not improved by the practice of submitting multiple specimen cups. Given the additional cost associated with separating specimens, the authors recommend during routine colposcopy that all cervical biopsies be sent for evaluation as a single pathology specimen unless a lesion of concern is identified in an area not normally excised during traditional excisional procedures.

RESUMEN

OBJECTIVE: The Laparoscopic Approach to Cervical Cancer (LACC) trial found that minimally invasive radical hysterectomy compared to open radical hysterectomy compromised oncologic outcomes and was associated with worse progression-free survival (PFS) and overall survival (OS) in early-stage cervical carcinoma. We sought to assess oncologic outcomes at multiple centers between minimally invasive (MIS) radical hysterectomy and OPEN radical hysterectomy. METHODS: This is a multi-institutional, retrospective cohort study of patients with 2009 FIGO stage IA1 (with lymphovascular space invasion) to IB1 cervical carcinoma from 1/2007-12/2016. Patients who underwent preoperative therapy were excluded. Squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinomas were included. Appropriate statistical tests were used. RESULTS: We identified 1093 cases for analysis-715 MIS (558 robotic [78%]) and 378. OPEN procedures. The OPEN cohort had more patients with tumors >2 cm, residual disease in the hysterectomy specimen, and more likely to have had adjuvant therapy. Median follow-up for the MIS and OPEN cohorts were 38.5 months (range, 0.03-149.51) and 54.98 months (range, 0.03-145.20), respectively. Three-year PFS rates were 87.9% (95% CI: 84.9-90.4%) and 89% (95% CI: 84.9-92%), respectively (P = 0.6). On multivariate analysis, the adjusted HR for recurrence/death was 0.70 (95% CI: 0.47-1.03; P = 0.07). Three-year OS rates were 95.8% (95% CI: 93.6-97.2%) and 96.6% (95% CI: 93.8-98.2%), respectively (P = 0.8). On multivariate analysis, the adjusted HR for death was 0.81 (95% CI: 0.43-1.52; P = 0.5). CONCLUSION: This multi-institutional analysis showed that an MIS compared to OPEN radical hysterectomy for cervical cancer did not appear to compromise oncologic outcomes, with similar PFS and OS.

RESUMEN

Uterine carcinosarcomas have few adjuvant treatment options. Programmed cell death ligand-1 (PD-L1) expression in these tumors may predict response to checkpoint inhibitor therapies. An increase in PD-L1 expression has been shown in endometrial carcinomas with mismatch repair (MMR) deficiencies; however, few studies have evaluated PD-L1 expression in uterine carcinosarcomas. We examined PD-L1 expression in 41 cases of uterine carcinosarcoma using combined positive scores (CPS) and tumor proportion scores (TPS), and correlated with MMR status, p53 expression, and epithelial histotype. In addition to confirming the diagnosis of carcinosarcoma, the epithelial components were stratified based on endometrioid versus serous histology. Thirty-three cases (80%) were positive for PD-L1, defined as a CPS score of ≥1 or a TPS score of ≥1%. Twelve cases (29%) showed high expression of PD-L1, defined as a CPS score of ≥10 or a TPS score of ≥10%. The majority of the morphologically adjudicated carcinosarcomas had a serous epithelial component (83%) rather than endometrioid (17%), which was reinforced by aberrant p53 staining predominantly within cases with serous morphology. The majority of carcinosarcomas showed at least focal PD-L1 expression, predominantly in tumor-associated immune cells. Carcinosarcomas with endometrioid morphology were significantly more likely to have high-level PD-L1 (5/7 vs. 7/34; P=0.015). MMR-deficient carcinosarcomas were also more likely to have high-level PD-L1 (2/3 vs. 10/28); however, this did not reach statistical significance (P=0.2) and overall MMR-deficiency was uncommon (3 cases, 7%). These findings suggest that PD-L1 may be additive to MMR testing as a predictive biomarker for checkpoint inhibitor vulnerability in carcinosarcomas.

RESUMEN

PURPOSE OF REVIEW: Robotic pancreas transplantation is a novel procedure that aims to reduce surgical invasiveness, and thereby limit complications related to the surgical access. Given that few centers are providing robotic transplantation, this review serves as a state of the science article to outline early experiences and highlight areas for future research. RECENT FINDINGS: Pancreas transplantation results in relatively high rates of wound and other surgical complications that are known to deleteriously impact outcomes. The minimally invasive, robotic-assisted approach decreases wound complications. Because of the obesity epidemic, overweight and obese status is encountered in an increasing number of transplant candidates. These candidates are subject to increased wound-related complications and most benefit from a robotic approach. The first clinical reports on laparoscopic, robotic-assisted kidney and pancreas transplantation indicate a significant decrease in wound complications and excellent outcomes in obese patients otherwise denied access to transplantation. SUMMARY: With excellent results achieved in surgically challenging patients and further accumulation of experience, laparoscopic, robotic-assisted pancreas and kidney transplantation may evolve to a new standard approach.

RESUMEN

OBJECTIVE: The aim of this study was to assess hormone replacement therapy (HRT) and bone care health maintenance practices for cervical cancer patients with iatrogenic menopause, and, secondarily, to investigate the potential impact of specific demographic and clinical factors. METHODS: Women diagnosed with iatrogenic menopause due to cervical cancer treatment between January 1, 2005 and December 31, 2015 were identified from the University of Virginia's tumor registry. Univariable data were analyzed using Wilcoxon rank sum, Chi square, and Fisher's exact test; multivariable analysis was conducted using logistic regression. RESULTS: Two hundred and two women were included for analysis. Ninety-seven of these women (48.0%) received counseling and/or a prescription for HRT. After multivariable analysis, older age at diagnosis (adjusted OR 0.940, 95% CI 0.890-0.993, p=0.0270) and uninsured payer status (adjusted OR 0.455, 95% CI 0.212-0.977, p=0.0435) were associated with a decreased likelihood of receiving counseling or a prescription for HRT. A longer duration of follow-up was associated with the primary outcome with an adjusted OR of 1.011 (95% CI 1.001-1.020, p=value 0.0252). Dual-energy X-ray absorptiometry scans (DEXA) were infrequent and received by only 17/197 (8.6%) of all women. CONCLUSIONS: Fewer than half of all women received counseling and/or a prescription for HRT after diagnoses of iatrogenic menopause, and disparities were noted based on insurance status. These findings reflect a need for clearer guidelines on HRT during survivorship and improved efforts to reduce disparities in the distribution of survivorship care.

RESUMEN

OBJECTIVE: Determine whether metformin use is associated with improved survival in patients with ovarian, fallopian tube or primary peritoneal cancer. METHODS: All patients with a diagnosis of first epithelial ovarian cancer from 2007 to 2011 in the combined SEER-Medicare database were identified from the SEER registry primary site codes. Comorbidities, procedures and cancer treatment ICD-9 and HCPCS codes were used to search the Medicare claims files. Medication use was determined with National Drug Codes using the Medicare Part D event files. The primary outcome, overall survival, was assessed between metformin users and non-users using a Cox Proportional Hazards survival model. To control for confounding, metformin users were matched to non-metformin users using propensity scores. Effect of dosage on survival was assessed using discrete time survival analysis with pooled logistic regression (PLR). RESULTS: There were 2291 cases that met our inclusion criteria. Of these, 180 (7.9%) had been on metformin. The median age was 73years, with the majority of the population being White (83.5%) and treated with primary surgery (74.1%). Metformin use was not associated with overall survival in the entire cohort (HR 0.96, 95% CI 0.75-1.23) or in the matched sample cohort (HR 0.88, 95% CI 0.66-1.17). However, exploratory regression with time-varying coefficients suggests a protective metformin effect for women alive after 30months follow-up (HR=0.37, 95% 0.16-0.87). CONCLUSION: No statistically significant association was observed between metformin use and overall survival in a matched cohort of 360 ovarian cancer patients. However, exploratory modeling suggests metformin use may be protective in a certain subgroup of patients.

RESUMEN

AIM: The aim of this study was to evaluate whether frequency of complete blood count (CBC) testing during chemotherapy for gynecologic cancer impacts hospital admissions or rates of neutropenic fever. METHODS: A retrospective cohort study was performed at a single academic institution. Patients undergoing platinum-based chemotherapy for endometrial or ovarian cancer from January 2010 to December 2014 were identified from a clinical database. Patients receiving dose-dense chemotherapy or on a clinical trial were excluded. Electronic chart review collected demographic and clinical characteristics. The primary outcome was the rate of febrile neutropenia or hospital admission. RESULTS: A total of 174 patients were identified, 63 (36%) with endometrial and 111 (64%) with ovarian cancer. Fifty-four percent of patients received multiple CBC per cycle compared with 46% who only had one CBC per cycle. The majority of patients were treated with a platinum-based doublet (85%). Dose reductions, addition of granulocyte colony stimulating factor, and rates of grade 3 or 4 anemia and neutropenia were significantly associated with more frequent testing. There was no difference in rates of neutropenic fever (5.3 vs 3.8%, P = 0.45) or hospital admission (22.3 vs 21.3%, P = 0.86) for multiple versus single CBC monitoring. CONCLUSION: More frequent laboratory testing detected more cases of grade 3 or 4 hematopoietic toxicities and was associated with more interventions. There were no differences in number of hospitalizations or cases of neutropenic fever by frequency of laboratory testing, suggesting that it may be appropriate to decrease routine laboratory tests for select patients.

RESUMEN

OBJECTIVE: Uterine carcinosarcomas (UCSs) are aggressive tumors previously considered to be sarcomas, but now recognized as malignancies composed of metaplastic transformation of epithelial elements. Much of the management for UCS has been extrapolated from studies of endometrial carcinomas and sarcomas. This article critically reviews the literature pertinent to the pathology, pathogenesis, diagnosis and management of women with UCS. METHODS: MEDLINE was searched for English language literature on UCS with a focus on the past 20years. Given the rarity of this tumor, studies were not limited by design or number of reported patients. RESULTS: UCS is biologically a de-differentiated endometrial carcinoma with its own pathogenesis and molecular profile. It commonly presents with extrauterine disease which can be identified by comprehensive surgical staging. Most UCS patients are candidates for adjuvant chemotherapy. The role of radiation is less clear. Combination therapy, while commonly used, has not been studied in depth. The high recurrence rate and poor overall survival for UCS suggest an ongoing need for clinical trials for UCS specifically. CONCLUSIONS: UCS represents a distinct subtype of uterine malignancy, and should be studied as such via focused clinical trials.

RESUMEN

OBJECTIVE: Literature suggests that para-aortic lymphadenectomy (para-aortic lymph node dissection [PALND]) has a therapeutic benefit for women with intermediate- to high-risk endometrial adenocarcinoma. We hypothesized that the observed survival advantage of PALND is a reflection of the general health of the patient rather than a therapeutic benefit of surgery. METHODS: Women with intermediate- to high-risk endometrial adenocarcinoma diagnosed from 2002 to 2009 at a single institution were identified. Medical comorbidities, pathology, and survival information were abstracted from the medical record. The χ test or the t test was used for univariate analysis. Overall survival (OS) and disease-specific survival (DSS) were calculated using the Kaplan-Meier method. RESULTS: A total of 253 women with a mean age of 64 years were identified. Of these women, 174 had a pelvic lymphadenectomy (pelvic lymph node dissection [PLND]) and 82 had PLND and PALND. The rate of positive nodes was 13% (23/174) for the women who had PLND and was 7% (6/82) for those who had PLND and PALND. Only 1.2% (1/82) of the women who had PLND and PALND had negative pelvic but positive para-aortic nodes. The patients who had PALND had a lower body mass index and were less likely to have significant medical comorbidities. The patients who had PALND had improved 5-year OS (96% vs 82%, P = 0.007) but no difference in 5-year DSS (96% vs 89%, P value = not significant). CONCLUSIONS: Women with intermediate- to high-risk endometrial adenocarcinoma who undergo PALND have improved OS but no improvement in DSS. The lack of difference in DSS supports the hypothesis that underlying comorbidities as opposed to lack of PALND result in poorer outcome.

RESUMEN

OBJECTIVE: To characterize the safety and feasibility of robotic adnexal surgery during pregnancy, and to compare surgical and obstetric outcomes for robotic versus laparoscopic treatment of adnexal masses during pregnancy. STUDY DESIGN: A retrospective cohort study of all cases of robotic resection of adnexal masses in gravid patients performed at our institution between 2006 and 2009 compared with 50 consecutive historic laparoscopic controls performed between 1999 and 2007. RESULTS: During the study period, 19 parturients underwent planned robotic resection of adnexal masses, all of which were uncomplicated. Compared with 50 consecutive laparoscopic controls, no differences in operative time, conversion to laparotomy, intraoperative or postoperative complications, or observed obstetric outcomes were apparent. The robotic cohort had a significantly shorter length of hospital stay (p < 0.01) and estimated blood loss (p = 0.02). CONCLUSION: Robotic resection of adnexal masses during pregnancy appears both safe and feasible, with similar surgical outcomes when compared with a historic laparoscopic cohort.

RESUMEN

Cervical cancer is the fourth most common cancer worldwide, with over 600,000 new cases annually and approximately 350,000 cancer-related deaths per year. The disease burden is disproportionately distributed, with cancer-related mortality ranging from 5.2 deaths per 100,000 individuals in highly-developed countries, to 12.4 deaths per 100,000 in less-developed countries. This article is a review of the current screening recommendations and potential future recommendations.

RESUMEN

OBJECTIVES: The objective of this pilot study was to determine if frailty predicts surgical complications among elderly women undergoing gynecologic oncology procedures. METHODS: A cohort of gynecologic oncology patients age ≥ 65, undergoing surgery between March and December 2011 was identified. Frailty was evaluated using a validated assessment tool. The primary outcome measure was 30 day postoperative complication rate. RESULTS: Forty women were approached for study entry and 37 (92%) enrolled. The mean age was 73 years (range 65-95). The majority of women had a malignancy and underwent a major abdominal surgical procedure. Twenty-one women (57%) were not frail, 10 (27%) were intermediately frail and 6 (16%) were frail. There was no difference in age or prevalence of medical comorbidities between groups. Frail women had a significantly higher BMI compared to intermediately frail and not frail women, (36.0, 31.5 and 26.1 kg/m(2), p=0.02). The rate of 30-day surgical complications increased with frailty score and was 24%, versus 67% for women who were not frail as compared to the frail (p=0.04). CONCLUSIONS: Pre-operative frailty assessment is well accepted by gynecologic oncology patients and feasible in a clinic setting. Frail women had a higher BMI, indicating that low body weight is not a marker for frailty, and had a significantly higher rate of 30-day postoperative complications in this pilot study. Initial findings support the concept of measuring frailty as a possible predictor for postoperative morbidity that will allow for improved patient counseling and decision making.

RESUMEN

OBJECTIVE: To evaluate the impact of adjuvant post-operative therapy in women with early stage uterine carcinosarcoma. METHODS: After IRB approval was obtained at all sites, a multi-center retrospective study of women with FIGO stage I-II uterine carcinosarcoma diagnosed from 1997 to 2007 was conducted. Post-operative treatment included observation (OBS), radiation (RT), chemotherapy (CT) alone or with RT (CT+RT). Data analyzed included demographic and pathologic factors, adjuvant therapy outcomes, and time-to-event information. The Kaplan-Meier method was used to estimate time-to-event functions. Cox regression modeling was used to examine the impact of selected covariates on progression free survival (PFS), and overall survival (OS). RESULTS: 111 women were identified: 94 (85%) had stage I and 17 (15%) had stage II uterine carcinosarcoma. Forty-four women (40%) did not receive adjuvant therapy (OBS), 29 (26%) women had adjuvant CT, 23 (20%) women underwent RT and 15 (14%) women underwent RT+CT. Seventy-three patients were alive without disease and 38 had progressed or died at the close of data collection. In multivariate analysis, CT (p=0.003), LVSI (p<0.0001) and a pre-existing cancer (p=0.004) were most predictive of PFS. LVSI was predictive of shortened OS (p=0.01). CONCLUSIONS: In women with FIGO stage I-II uterine carcinosarcoma, adjuvant chemotherapy is associated with improved PFS compared to radiation or observation alone. Ongoing clinical trials will clarify the role of chemotherapy in women with this disease.

RESUMEN

Uterine carcinosarcoma (UCS) is an aggressive malignancy with few treatment options. A recent clinical trial has shown an increase in progression-free survival in patients with human epidermal growth factor receptor 2 (HER2)-positive serous endometrial carcinomas treated with anti-HER2-targeted therapies. Few studies have evaluated HER2 expression/amplification in UCS. Similar to serous endometrial carcinoma, the majority of UCS have TP53 mutations and a serous epithelial component, suggesting that UCS may show similar rates of HER2 positivity and therapeutic response. Therefore, we evaluated HER2 expression/amplification in a cohort of UCS over a 5-year period. HER2 immunohistochemistry (IHC) and chromogenic in situ hybridization were performed on tissue microarray and whole tissue sections and scored according to the most recent clinical trial recommendations. Three of 48 UCS (6%) had strong (3+) HER2 IHC expression, and 3 cases (6%) were equivocal (2+). Seven cases (15%) had HER2 amplification by chromogenic in situ hybridization, including all 3 with overexpression and 2 that were equivocal by IHC. Mismatch repair (MMR) protein, p53, and programmed cell death-ligand 1 (PD-L1) expression status was obtained from prior whole section analyses. All HER2-positive cases had a serous morphology and aberrant p53 expression. Only minimal PD-L1 expression was seen in the HER2-positive cases, and none had MMR loss. A subset of UCS with serous morphology have overexpression and/or amplification of HER2, which may predict response to HER2-targeted therapies. HER2-positive UCS may be less susceptible to immune checkpoint inhibition as they uncommonly show MMR deficiency and/or strong PD-L1 expression. Thus, HER2-targeted therapies could be of clinical utility in a subset of UCS without other adjuvant treatment options.

RESUMEN

BACKGROUND: Analysing kinematic and video data can help identify potentially erroneous motions that lead to sub-optimal surgeon performance and safety-critical events in robot-assisted surgery. METHODS: We develop a rubric for identifying task and gesture-specific executional and procedural errors and evaluate dry-lab demonstrations of suturing and needle passing tasks from the JIGSAWS dataset. We characterise erroneous parts of demonstrations by labelling video data, and use distribution similarity analysis and trajectory averaging on kinematic data to identify parameters that distinguish erroneous gestures. RESULTS: Executional error frequency varies by task and gesture, and correlates with skill level. Some predominant error modes in each gesture are distinguishable by analysing error-specific kinematic parameters. Procedural errors could lead to lower performance scores and increased demonstration times but also depend on surgical style. CONCLUSIONS: This study provides insights into context-dependent errors that can be used to design automated error detection mechanisms and improve training and skill assessment.

RESUMEN

OBJECTIVE: To validate the Mayo algorithm to intraoperatively identify women with endometrial cancer in whom lymphadenectomy may be safely omitted. METHODS: A multi-center retrospective chart review 1977-2010 was completed using two independent institutional endometrial cancer databases. Eligibility criteria were grade 1 or 2 endometrial carcinoma, low-risk histology, and myometrial invasion ≤ 50% on intraoperative pathology consultation; patients were considered to satisfy the Mayo criteria if, in addition to these, tumor diameter on the final pathology report was ≤ 2 cm. Analysis of nodal metastases, recurrent disease, and progression-free survival (PFS) using the Kaplan-Meier method was performed. RESULTS: Six hundred and two patients met inclusion criteria for the study. Of 110 patients satisfying the Mayo algorithm with an adequate lymphadenectomy, 2 (1.8%) were diagnosed with lymph node metastasis and 4 (3.6%) subsequently developed recurrent disease. The Mayo algorithm identified with a 98.2% negative predictive value women who would not benefit from a lymphadenectomy. There was no significant difference in recurrence rate or PFS between women who underwent lymphadenectomy and those who did not when the Mayo algorithm was satisfied. CONCLUSIONS: The Mayo algorithm intraoperatively identifies tumor characteristics of low-risk disease in endometrial carcinoma that predict a very low likelihood of nodal metastasis and recurrence. Although a small number of patients with advanced stage disease may be missed when applying the Mayo criteria, there is no apparent survival benefit to lymphadenectomy for patients satisfying this algorithm, and these data support its use at other institutions.

RESUMEN

BACKGROUND: Many centres deny obese patients with a body mass index (BMI) >35 access to kidney transplantation due to increased intraoperative and postoperative complications. METHODS: From August 2017 to December 2019, 73 consecutive cases of kidney transplantation in morbidly obese patients were enrolled at a single university at the initiation of a robotic transplant surgery program. Outcomes of patients who underwent robotic assisted kidney transplant (RAKT) were compared to frequency-matched patients undergoing open kidney transplant (OKT). RESULTS: A total of 24 morbidly obese patients successfully underwent RAKT, and 49 obese patients received an OKT. The RAKT group developed fewer surgical site infections (SSI) than the OKT group. Graft function, creatinine, and glomerular filtration rate (GFR) were similar between groups 1 year after surgery. Graft and patient survival were 100% for both groups. CONCLUSIONS: RAKT offers a safe alternative for morbidly obese patients, who may otherwise be denied access to OKT.

RESUMEN

OBJECTIVES.: To assess progression-free (PFS) and overall survival (OS) for women with cervical cancer who underwent type III robotic radical hysterectomy (RRH). METHODS.: A retrospective analysis of women who underwent RRH from 2005 to 2008 was performed. The data analyzed included patient demographics, histology, clinical stage, surgical margins, lymph node and disease status. Comparison was made to a group of historical open radical hysterectomies. Survival statistics were analyzed using the Kaplan-Meier method. RESULTS.: Seventy-one women underwent attempted RRH during the study period. Eight were excluded from analysis, 4 for non-cervical primary and 4 cases aborted due to extent of disease. Squamous was the most common histology (62%) followed by adenocarcinoma (32%). Median patient age was 43 years. There was one intraoperative complication (asystole after induction) and two postoperative complications (ICU admission to rule out myocardial infarction and reoperation for cuff dehiscence). Of the patients who underwent RRH, 32% received whole-pelvis radiation with chemo sensitization. The median follow-up was 12.2 months (range 0.2-36.3 months). Kaplan-Meier survival analysis demonstrated 94% PFS and OS at 36 months due to the recurrence and death of one patient. Compared with a historical cohort at our institution, there was no statistically significant difference in PFS (P=0.27) or OS (P=0.47). CONCLUSIONS.: RRH is safe and feasible and has been shown to be associated with improved operative measures. This study shows that at 3 years, RRH appears to have PFS and OS equivalent to that of traditional laparotomy. Longer follow-up is needed, but early data are supportive of at least equivalent oncologic outcomes compared with other surgical modalities.
