Cancer screening with multicancer detection tests: A translational science review.

Multicancer detection (MCD) tests use a single, easily obtainable biospecimen, such as blood, to screen for more than one cancer concurrently. MCD tests can potentially be used to improve early cancer detection, including cancers that currently lack effective screening methods. However, these tests have unknown and unquantified benefits and harms. MCD tests differ from conventional cancer screening tests in that the organ responsible for a positive test is unknown, and a broad diagnostic workup may be necessary to confirm the location and type of underlying cancer. Among two prospective studies involving greater than 16,000 individuals, MCD tests identified those who had some cancers without currently recommended screening tests, including pancreas, ovary, liver, uterus, small intestine, oropharyngeal, bone, thyroid, and hematologic malignancies, at early stages. Reported MCD test sensitivities range from 27% to 95% but differ by organ and are lower for early stage cancers, for which treatment toxicity would be lowest and the potential for cure might be highest. False reassurance from a negative MCD result may reduce screening adherence, risking a loss in proven public health benefits from standard-of-care screening. Prospective clinical trials are needed to address uncertainties about MCD accuracy to detect different cancers in asymptomatic individuals, whether these tests can detect cancer sufficiently early for effective treatment and mortality reduction, the degree to which these tests may contribute to cancer overdiagnosis and overtreatment, whether MCD tests work equally well across all populations, and the appropriate diagnostic evaluation and follow-up for patients with a positive test.

Challenges in implementation of molecular classification in early stage endometrial cancer-An NRG Oncology cooperative group mixed-methods study.

BACKGROUND: Professional guidelines recommend molecular profiling for mismatch repair (MMR), p53, and polymerase epsilon (POLE) status in endometrial cancer (EC). However, adoption in the United States has not been documented, and barriers to the implementation of testing have not been described. METHODS: In this mixed-methods study, implementation science frameworks were used to develop a quantitative survey. Gynecologic oncologists, medical oncologists, radiation oncologists, and pathologists affiliated with NRG Oncology programs were contacted through snowball sampling and were surveyed during 2022-2023. A subset of respondents was interviewed. Statistical and thematic analyses were performed. RESULTS: At least 403 NRG Oncology-affiliated providers were contacted for the survey, and 107 (26.6%) responded. Greater than 90% of respondents perceived POLE, MMR, and p53 status as important for clinical care. MMR and p53 tests were perceived as easy to obtain, but only 24.2% of respondents reported that POLE testing was moderately or very easy to obtain. Respondents from academic sites reported better access to molecular classification and perceived greater importance of molecular classification compared with respondents from community sites. In thematic analysis of 13 qualitative interviews, cost concerns were reported as large barriers to testing. Interviewees reported a desire for prospective data to guide treatment selection based on classification results. CONCLUSIONS: Although integrating molecular classification into standard pathologic reporting is recommended, and clinicians perceive molecular profiling in early stage EC as important, survey respondents noted significant implementation barriers. Implementation challenges that differ between community oncology and academic practice settings were identified. Strategies to improve equitable access to molecular classification of early stage EC are needed.

What's in it for me?: A value assessment of gynecologic cancer clinical trials for Black women.

OBJECTIVE: Underrepresented groups may be dissuaded from clinical trial participation without perceived value. We therefore comprehensively assessed gynecologic cancer clinical trial protocols for the inclusion of items of value most important to Black individuals. METHODS: ClinicalTrials.gov was queried for NCI-sponsored gynecologic cancer clinical trials in the US between Jan.1994 and Nov.2021. Pre-specified return of value (ROV) items were abstracted from each protocol. Inclusion proportions were calculated for each ROV item and temporal changes assessed with chi-square tests. Temporality of proportional trends was further assessed by slope and departure from linearity calculations. RESULTS: 279 gynecologic cancer clinical trials were included. Most commonly trials had first accrual in 2001-2007 (37%) and involved ovarian cancer (48%), phase II studies (53%), and chemotherapy (60%) or targeted therapy (34%). Trials often included ROV items in basic information (99%), medical record information (99%), and imaging (82%). 41% of trials included ROV items in biomarker testing, 20% genetic testing, and 20% in patient-reported outcome questionnaires. Over time, there were significant increases in the proportion of trials that included genetic (3% to 51%; p < 0.001) and biomarker testing (14 to 78%, p < 0.001). Information on lifestyle risk factors was rare (1%). No trials included ROV items in ancestry, how to connect with other participants, or remuneration. CONCLUSIONS: Gynecologic cancer clinical trials include few design elements that provide high value to Black individuals like lifestyle risk factors, ancestry, and remuneration. In any multi-pronged effort to improve diversity in clinical trial enrollment, inclusion of items valued by Black individuals should be considered.

Chronic conditions in women: the development of a National Institutes of health framework.

Rising rates of chronic conditions were cited as one of the key public health concerns in the Fiscal Year (FY) 2021 U.S. Senate and House of Representatives appropriations bills, where a review of current National Institutes of Health (NIH) portfolios relevant to research on women's health was requested. Chronic conditions were last defined by the US Department of Health and Human Services (HHS) in 2010. However, existing definitions of chronic conditions do not incorporate sex or gender considerations. Sex and gender influence health, yet significant knowledge gaps exist in the evidence-base for prevention, diagnosis, and treatment of chronic diseases amongst women. The presentation, prevalence, and long-term effects of chronic conditions and multimorbidity differs in women from men. A clinical framework was developed to adequately assess the NIH investment in research related to chronic conditions in women. The public health needs and NIH investment related to conditions included in the framework were measured. By available measures, research within the NIH has not mapped to the burden of chronic conditions among women. Clinical research questions and endpoints centered around women can be developed and implemented; clinical trials networks with expanded or extended eligibility criteria can be created; and data science could be used to extrapolate the effects of overlapping or multiple morbidities on the health of women. Aligning NIH research priorities to address the specific needs of women with chronic diseases is critical to addressing women's health needs from a life course perspective.

Current gaps and opportunities in screening, prevention, and treatment of cervical cancer.

In their fiscal year 2021 reports, the US House and Senate Appropriations Committees requested that the National Institutes of Health (NIH) evaluate current research related to women's health and topics that include stagnant cervical cancer survival. In response, the NIH Office of Research on Women's Health, with input from women's health experts; members of the public; representatives from NIH institutes, centers, and offices; and members of the NIH Advisory Committee on Research on Women's Health, reviewed the public health needs and current NIH activities on cervical cancer. The Advancing NIH Research on the Health of Women: A 2021 Conference held in October 2021 reviewed these findings and allowed the identification of opportunities to strengthen research. In this review, the authors summarize public health needs related to cervical cancer and NIH activities in this realm. Cervical cancer has become a rare disease in the United States, yet significant portions of the US population remain under screened or unscreened for cervical cancer, human papillomavirus vaccination rates remain low, access to high-quality treatment remains a challenge for many, and large inequities by race and ethnicity persist. Novel, inclusive, and intentional research is needed to produce improvements in cervical cancer survival within the United States.

Improving the quality of care for patients with advanced epithelial ovarian cancer: Program components, implementation barriers, and recommendations.

The high lethality of ovarian cancer in the United States and associated complexities of the patient journey across the cancer care continuum warrant an assessment of current practices and barriers to quality care in the United States. The objectives of this study were to identify and assess key components in the provision of high-quality care delivery for patients with ovarian cancer, identify challenges in the implementation of best practices, and develop corresponding quality-related recommendations to guide multidisciplinary ovarian cancer programs and practices. This multiphase ovarian cancer quality-care initiative was guided by a multidisciplinary expert steering committee, including gynecologic oncologists, pathologists, a genetic counselor, a nurse navigator, social workers, and cancer center administrators. Key partnerships were also established. A collaborative approach was adopted to develop comprehensive recommendations by identifying ideal quality-of-care program components in advanced epithelial ovarian cancer management. The core program components included: care coordination and patient education, prevention and screening, diagnosis and initial management, treatment planning, disease surveillance, equity in care, and quality of life. Quality-directed recommendations were developed across 7 core program components, with a focus on ensuring high-quality ovarian cancer care delivery for patients through improved patient education and engagement by addressing unmet medical and supportive care needs. Implementation challenges were described, and key recommendations to overcome barriers were provided. The recommendations emerging from this initiative can serve as a comprehensive resource guide for multidisciplinary cancer practices, providers, and other stakeholders working to provide quality-directed cancer care for patients diagnosed with ovarian cancer and their families.

Results of an early safety analysis of a study of the combination of pembrolizumab and pelvic chemoradiation in locally advanced cervical cancer.

BACKGROUND: Immune checkpoint inhibitors are being considered for locally advanced cervical cancer (LACC) together with standard-of-care pelvic chemoradiation (CRT). However, the safety of the combination and its optimal schedule are unknown. Defining the safety of the combination is a primary objective of a study examining concurrent and sequential schedules. This article presents a safety analysis that was fully accrued and met reporting requirements. METHODS: Pembrolizumab was given after CRT (arm 1) or during CRT (arm 2) according to a randomized phase 2 design. Patients who were 18 years old or older and had LACC (stages IB-IVA according to the 2009 International Federation of Gynecology and Obstetrics system) were randomized 1:1 to the treatment regimens. The CRT was identical in the 2 arms. Pembrolizumab was administered every 3 weeks for 3 doses; no maintenance was allowed. All patients receiving any treatment were evaluated for safety. Safety assessments included the incidence and severity of adverse events (AEs) and the occurrence of protocol-defined dose-limiting toxicity (DLT) through 30 days after the last pembrolizumab infusion. RESULTS: As of August 2019, 52 of the 88 planned patients had completed treatment and were evaluable for toxicity. Treatment-related grade 2 or higher toxicity was experienced by 88%; 11 had at least 1 grade 4 AE, and another 23 had at least 1 grade 3 AE. Grade 1 or higher diarrhea was reported in 34 patients (65%; 50% of these were grade 1), and there was no difference between arms (63% in arm 1 vs 68% in arm 2). Two patients experienced 3 DLTs. Most patients completed cisplatin (100% in arm 1 vs 82% in arm 2); 83% in both arms completed all pembrolizumab. CONCLUSIONS: Preliminary results support the safety and feasibility of adding pembrolizumab to pelvic CRT concurrently or sequentially. LAY SUMMARY: Pembrolizumab is a humanized antibody against programmed cell death protein 1 that is used in cancer immunotherapy. Preliminary data suggest that pembrolizumab can be safely combined with chemotherapy and pelvic radiation in the treatment of locally advanced cervical cancer. Future studies of the addition of immunotherapy to traditional chemoradiation are planned to determine the best way to deliver the treatment and whether any improvement is seen with the addition of immunotherapy to traditional therapy.

Take me to your leader: Reporting structures and equity in academic gynecologic oncology.

OBJECTIVE: Gynecologic oncology includes increasing percentages of women. This study characterizes representation of faculty by gender and subspecialty in academic department leadership roles relevant to the specialty. METHODS: The American Association of Medical Colleges accredited schools of medicine were identified. Observational data was obtained through institutional websites in 2019. RESULTS: 144 accredited medical schools contained a department of obstetrics and gynecology with a chair; 101 a gynecologic oncology division with a director; 98 a clinical cancer center with a director. Women were overrepresented in academic faculty roles compared to the US workforce (66 vs 57%, p < 0.01) but underrepresented in all leadership roles (p < 0.01). Departments with women chairs were more likely to have >50% women faculty (90.2 vs 9.8%, p < 0.01); and have larger faculties (80.4 vs 19.6% >20 faculty, p = 0.02). The cancer center director gender did not correlate to departmental characteristics. A surgically focused chair was also associated with >50% women faculty (85.7 vs 68.3%, p = 0.03); faculty size >20 (85.7 vs 61.4%, p < 0.01); and a woman gynecologic oncology division director (57.6 vs 29.4%, p < 0.01; 68.4 vs 31.7%, p < 0.01) and gynecologic oncology fellowship (50 vs 30.4%, p < 0.01; 59.1 vs 32%, p < 0.01). Gynecologic oncology leadership within cancer centers was below expected when incidence and mortality to leadership ratios were examined (p < 0.01, p < 0.01). CONCLUSION: Within academic medical schools, women remain under-represented in obstetrics and gynecology departmental and cancer center leadership. Potential benefits to gynecologic oncology divisions of inclusion women and surgically focused leadership were identified.

Has a critical mass of women resulted in gender equity in gynecologic surgery?

Gender equity in medicine and surgery has recently received widespread attention. Unlike surgical specialties that remain predominantly male, the majority of obstetrician-gynecologists have been women for nearly a decade, and women have composed the majority of trainees since the 1990s. Despite a critical mass of women, biases related to gender persist in the field. Professional and behavioral expectations of men and women gynecologists remain different for patients and workplace colleagues. Gender discrimination and sexual harassment are still experienced at high rates by both trainees and obstetrician-gynecologists in practice. In addition, in other surgical fields, women gynecologic surgeons face a gender wage gap that is unexplained by differences in experience, hours worked, or subspecialty training. Academic advancement and the attainment of leadership positions remain a challenge for many women. Policies related to pregnancy and parenting may disproportionately affect the careers of women gynecologists. This article presents peer-reviewed evidence relevant to gender equity in the workplace and suggests proactive interventions to ensure diversity and inclusion for gynecologic surgeons.

Complications and Survivorship Trends After Primary Debulking Surgery for Ovarian Cancer.

BACKGROUND: We examined factors associated with postoperative complications, 1-year overall and cancer-specific survival after epithelial ovarian cancer (EOC) diagnosis. METHODS: Patients who underwent surgery for EOC between 2004 and 2013 were included. Multivariable models analyzed postoperative complications, overall survival, and cancer-specific survival. RESULTS: Among 5223 patients, surgical complications were common. Postoperative complications correlated with increased odds of overall and disease-specific survival at 1 y. Receipt of chemotherapy was similar among women with and without postoperative complications and was independently associated with a reduction in the hazard of overall and disease-specific death at 1-year. Extensive pelvic and upper abdomen surgery resulted in 2.26 times the odds of postoperative complication, but was associated with longer 1-year overall 0.53 (0.35, 0.82) and disease-specific survival 0.54 (0.34, 0.85). CONCLUSIONS: Although extent of surgery was associated with complications, the survival benefit from comprehensive surgery offset the risk. Tailored surgical treatment for women with EOC may improve outcomes.

The role of menopausal hormone therapy in women with or at risk of ovarian and breast cancers: Misconceptions and current directions.

For women who are candidates for menopausal hormone therapy (MHT), estrogen can provide relief from symptomatic menopause, decrease rates of chronic illnesses, and improve health-related quality of life. However, confusion surrounds the evidence regarding the impact of exogenous estrogen and progesterone on the breast and ovary. Available data regarding the risks of MHT (estrogen and/or progestin) related to the development of breast and ovarian cancer are often inconsistent or incomplete. Modern molecular and genetic techniques have improved our understanding of the heterogeneity of breast and ovarian cancer. This enhanced understanding of the disease has impacted our understanding of carcinogenesis. Treatment options have evolved to be more targeted toward hormonal therapy for certain subtypes of disease, whereas cytotoxic chemotherapy remains the standard for other histological and molecular subtypes. The role of MHT in the breast and ovarian cancer survivor, as well as women who are at high risk for the development of hereditary breast and ovarian cancer, remains controversial despite evidence that this treatment can improve quality of life and survival outcomes. Through this article, we examine the evidence for and against the use of MHT with a focus on women who have or are at high risk for breast and ovarian cancer.

Awareness and acceptability of population-based screening for pathogenic BRCA variants: Do race and ethnicity matter?

OBJECTIVE: To evaluate awareness and acceptability of population-based BRCA testing among an unselected population of women presenting for annual gynecologic health assessment, with secondary objective to determine if a racial disparity exists in acceptability and awareness of this screening strategy. METHODS: Women presenting for routine gynecologic care in an outpatient setting of a single academic institution were anonymously surveyed. Survey collected age, self-identified race and ethnicity, education level, personal and family history of breast and/or ovarian cancer (BOC), awareness and interest, and willingness to pay out of pocket for testing. Responses were compared with bivariate and multivariate analysis. RESULTS: Interest in testing was expressed in 150 of 301 (45.1%) of participants. Women with a family history of BOC were more likely to be interested in testing than those without (OR = 1.9 (1.0-3.6)). Interest in testing was associated willingness to pay (OR = 3.3 (1.7-6.4)). Higher education level was associated with awareness of testing (OR = 9.9 (2.0-49.7)). Interest in testing was similar between racial groups, but awareness and willingness to pay for testing were higher among White women. Multivariate analysis with adjustment for education level confirmed that Black and Hispanic women were less likely to have awareness of genetic testing compared to White women and non-Hispanic Women, respectively (OR = 0.11 (0.05-0.3); OR = 0.10 (0.01-0.8)). CONCLUSIONS: Interest in genetic testing among women in the general population is high. Despite interest, awareness of BRCA is poor among Black and Hispanic women even when adjusting for education level.

Reproductive health care across the lifecourse of the female cancer patient.

Reproductive health is a key component of cancer care and survivorship, encompassing gynecologic issues ranging from contraception and fertility to treatment of sexual dysfunction and menopause. Yet, oncology providers are often unfamiliar with the management of gynecologic issues. In order to address the unmet needs of female cancer patients, reproductive health should be addressed at the time of cancer diagnosis and continue through survivorship. Universal screening for pregnancy intention can guide counseling on contraception and fertility preservation. Safe and efficacious contraceptive options for both patients undergoing active treatment and cancer survivors are available and can often offer non-contraceptive benefits such as regulation of menses. Prompt referral to reproductive endocrinology specialists allows patients to explore options for fertility preservation prior to the receipt of cancer-directed therapies. Due to a rapid drop in hormone levels, treatment-induced menopause often results in severe symptoms. In patients with induced menopause, balancing the risks of hormone therapy compared to the decreased quality of life and health concerns associated with early menopause may help patients with difficult decisions regarding symptom control. Cancer treatment impacts sexual function with both physical changes to the vulvovaginal tissues and altered relationship dynamics. Open discussions on the impact to sexual health are paramount to quality of life after cancer. While more data is needed in many areas, proactive management of reproductive health issues is crucial to quality of life in cancer survivorship. In this article, we review contemporary management of the reproductive health of the female cancer patient.

Disparities in health-related quality of life in women undergoing treatment for advanced ovarian cancer: the role of individual-level and contextual social determinants.

PURPOSE: Social determinants may influence health-related quality of life (HRQOL) among women with ovarian cancer, potentially creating disparities in clinical outcomes. We investigated the relationship between HRQOL and social determinants of health, including travel distance to access cancer care and health insurance type, among women participating in a randomized trial of primary adjuvant treatment for advanced ovarian cancer. METHODS: The Functional Assessment of Cancer Therapy-Ovarian (FACT-O) questionnaire captured HRQOL (physical well-being, functional well-being, ovarian-specific, and trial outcome index [TOI]) prior to chemotherapy (baseline), during the trial, and 84 weeks after initiation of chemotherapy for women with advanced epithelial ovarian, primary peritoneal, or fallopian tube cancer. We constructed bivariate and multivariable linear mixed effects models examining the associations of social determinants of health (individual-level and contextual factors) with HRQOL scores at 84 weeks, clustering participants (n = 993) within treatment centers, and Census regions and controlling for baseline HRQOL. RESULTS: Most individual-level (race, age, cancer stage, adverse events) and contextual (travel distance to treatment center, community socioeconomic status) factors were not statistically significantly associated with HRQOL. Compared to participants with private health insurance, other participants had lower mean HRQOL (physical well-being: public insurance, - 1.00 (standard error[SE] = 0.49) points, uninsured, - 1.93 (SE = 0.63) points; functional well-being: public, - 1.29 (SE = 0.59), uninsured, - 1.98 (SE = 0.76); ovarian cancer-specific: public, - 1.60 (SE = 0.59), uninsured, - 1.66 (SE = 0.75); TOI: public, - 3.81 (SE = 1.46), uninsured, - 5.51 (SE = 1.86); all p < .05). CONCLUSIONS: Private health insurance was associated with improved HRQOL at the completion of treatment for advanced stage ovarian cancer. Implications of health insurance on HRQOL should be further investigated, particularly among women with ovarian cancer who receive standard of care treatment.

Hysterectomy-corrected rates of endometrial cancer among women younger than age 50 in the United States.

PURPOSE: This analysis describes the impact of hysterectomy on incidence rates and trends in endometrioid endometrial cancer in the United States among women of reproductive age. METHODS: Hysterectomy prevalence for states containing Surveillance, Epidemiology, and End Results (SEER) registry was estimated using data from the Behavioral Risk Factor Surveillance System (BRFSS) between 1992 and 2010. The population was adjusted for age, race, and calendar year strata. Age-adjusted incidence rates and trends of endometrial cancer among women age 20-49 corrected for hysterectomy were estimated. RESULTS: Hysterectomy prevalence varied by age, race, and ethnicity. Increasing incidence trends were observed, and were attenuated after correcting for hysterectomy. Among all women, the incidence was increasing 1.6% annually (95% CI 0.9, 2.3) and this increase was no longer significant after correction for hysterectomy (+ 0.7; 95% CI - 0.1, 1.5). Stage at diagnosis was similar with and without correction for hysterectomy. The largest increase in incidence over time was among Hispanic women; even after correction for hysterectomy, incidence was increasing (1.8%; 95% CI 0.2, 3.4) annually. CONCLUSION: Overall, endometrioid endometrial cancer incidence rates in the US remain stable among women of reproductive age. Routine reporting of endometrial cancer incidence does not accurately measure incidence among racial and ethnic minorities.

A contemporary framework of health equity applied to gynecologic cancer care: A Society of Gynecologic Oncology evidenced-based review.

Health disparities are defined as the preventable difference in the burden of disease, injury, and violence, or opportunity to achieve optimal health that socially disadvantaged populations experience compared to the population as a whole. Disparities in incidence and cancer outcomes for women with gynecologic malignancies have been well described particularly for American women of Black race. The etiology of these disparities has been tied to socio-economics, cultural, educational and genetic factors. While access to high quality treatment has been primarily linked to survival from cervical and ovarian cancer, innate biologic distinctions have been principally cited as reasons for differences in incidence and mortality in cancers of the uterine corpus. This article will update the framework of disparities to incorporate a broader understanding of the social determinants of health and how they affect health equity by addressing the root causes of disparities within the health care system. Special populations are identified who are at risk for health inequities which include but are not limited to Black race, underserved racial and ethnic minorities (e.g. indigenous peoples, low English fluency), trans/gender nonconforming people and rural populations. Each of these populations at risk have unique structural barriers within the healthcare system impacting gynecologic cancer outcomes. The authors provide practical recommendations for practitioners aimed at eliminating cancer related outcome disparities.

Moving forward with actionable therapeutic targets and opportunities in endometrial cancer: A NCI clinical trials planning meeting report.

The incidence of endometrial cancer (EC) in the U.S. has been rising, from an estimated annual incidence of 49,560 in 2013 to 61,380 in 2017. Meanwhile, the SEER-based relative survival of women with EC in the U.S. has remained flat [82.3% from 1987 to 1989, 82.8% from 2007 to 2013] and our recent increased understanding of EC biology and subtypes has not been translated into therapeutic advances. The U.S. National Cancer Institute (NCI) therefore convened a Uterine Clinical Trials Planning Meeting in January 2016 to initiate and accelerate design of molecularly-targeted EC trials. Prior to the meeting a group of experts in this field summarized available data, emphasizing data on human samples, to identify potentially actionable alterations in EC, and the results of their work has been separately published. The Clinical Trials Meeting planners focused on discussion of (1) novel trial designs, including window-of opportunity trials and appropriate control groups for randomized trials, (2) targets specific to serous carcinoma and promises and pitfalls of separate trials for women with tumors of this histology (3) specific recommendations for future randomized trials.

Narcotics reduction, quality and safety in gynecologic oncology surgery in the first year of enhanced recovery after surgery protocol implementation.

OBJECTIVES: Enhanced Recovery After Surgery (ERAS) programs are mechanisms for achieving value-based improvements in surgery. This report provides a detailed analysis of the impact of an ERAS program on patient outcomes as well as quality and safety measures during implementation on a gynecologic oncology service at a major academic medical center. METHODS: A retrospective review of gynecologic oncology patients undergoing elective laparotomy during the implementation phase of an ERAS program (January 2016 through December 2016) was performed. Patient demographics, surgical variables, postoperative outcomes, and adherence to core safety measures, including antimicrobial and venous thromboembolism (VTE) prophylaxis, were compared to a historical patient cohort (January 2015 through December 2015). Statistical analyses were performed using t-tests, Wilcoxon rank sum tests, and Chi squared tests. RESULTS: The inaugural 109 ERAS program participants were compared to a historical patient cohort (n=158). There was no difference in BMI, race, malignancy, or complexity of procedure between cohorts. ERAS patients required less narcotics (70.7 vs 127.4, p=0.007, oral morphine equivalents) and PCA use (32.1% vs. 50.6%, p=0.002). Despite this substantial reduction in narcotics, ERAS patients did not report more pain and in fact reported significantly less pain by postoperative day 3. There were no differences in length of stay (5days), complication rates (13.8% vs. 20.3%, p=0.17) or 30-day readmission rates (9.5 vs 11.9%, p=0.54) between ERAS and historical patients, respectively. Compliance with antimicrobial prophylaxis was 97.2%. However, 33.9% of ERAS patients received substandard preoperative VTE prophylaxis. CONCLUSIONS: ERAS program implementation resulted in reductions in narcotic requirements and PCA use without changes in length of stay or readmission rates. Compliance should be diligently audited during the implementation phase of ERAS programs, with special attention to adherence to pre-existing core safety measures.

Treatment-Related Radiation Toxicity Among Cervical Cancer Patients.

OBJECTIVE: The purpose of this study is to identify incidence of and factors associated with severe late toxicity in women treated with radiation for cervical cancer. MATERIALS AND METHODS: All patients with cervical cancer treated with radiation as primary or adjuvant therapy from 2005 to 2017 in a single academic institution were included. Records were reviewed for demographic information, Charlson Comorbidity Index, treatment details, toxicities, and outcomes. Patients with and those without severe late gastrointestinal toxicity (SLGIT), severe late genitourinary toxicity (SLGUT), or any SLGIT or SLGUT, defined as any toxicity (AT), were compared. Overall survival and progression-free survival were also compared. RESULTS: Of 179 patients identified, 21.2% had AT, 17.3% had SLGIT, and 10% had SLGUT. Estimated AT rate at 3 years was 24.2%. The mean duration of follow-up was 37 months (range, 3-146 months). Most patients (84.1%) received 3-dimensional conformal therapy, and 15.9% received intensity-modulated radiation therapy. Factors associated with AT were lower body mass index (24.9 vs 28.3, P = 0.043), white race (63.2% vs 44%, P = 0.035), and active tobacco smoking during treatment (59.5% vs 40.2%, P = 0.036). Any toxicity was not associated with 3-dimensional versus intensity-modulated radiation therapy planning, low-dose versus high-dose-rate brachytherapy or time to complete radiation treatment. Higher total cumulative radiation dose to clinical target volume was associated with SLGIT. Progression-free survival and overall survival were similar among patients with AT compared to those without toxicity. CONCLUSIONS: In patients with cervical cancer, radiation toxicity is correlated with lower body mass index, white race, and smoking. Despite technologic advances in radiotherapy planning and delivery, toxicity remains high and interventions to reduce the burden of treatment are needed.

The Utility of Sentinel Lymph Node Mapping in High-Grade Endometrial Cancer.

OBJECTIVE: The aim of this study was to report the utility and false-negative rates of sentinel lymph node (SLN) mapping during surgical staging of women with high-grade, apparent uterine-confined endometrial cancer. METHODS: This was a single-institution study performed at a high-volume academic center. From December 2012 to December 2015, women with high-grade endometrial cancer (grade 3 endometrioid, serous, clear cell, and carcinosarcoma) underwent SLN mapping via cervical injection followed by robot-assisted total laparoscopic hysterectomy and completion lymphadenectomy. Ultrastaging of SLNs was performed in patients with tumors with any degree of myoinvasion. Patient demographics, SLN test characteristics, treatment, and recurrence outcomes were prospectively evaluated for analysis. RESULTS: Fifty-two patients with high-grade histologic findings underwent SLN mapping followed by completion lymphadenectomy. The median patient age was 64 years, and median body mass index was 31.8 kg/m2. Most patients had either serous (46%) or grade 3 endometrioid histology (27%) on preoperative biopsy. Nine patients had nodal metastases, 7 of whom had metastases identified in SLNs. No low-volume nodal metastases were identified on ultrastaging. Two patients had false-negative SLN mapping (22%). After a median follow-up of 15.6 months, 14 recurrences (27%) were diagnosed; all were distant or multisite relapses. Sentinel lymph node mapping did not impact the choice of adjuvant therapy or recurrence risk in node-positive patients. CONCLUSIONS: Sentinel lymph node detection of metastases in patients with high-grade endometrial cancer is high, but false-negative results were encountered. More research is needed to determine whether SLN mapping can safely replace systemic lymphadenectomy in women with high-risk histologic findings.
