RESUMEN
BACKGROUND: Chemotherapy-induced alopecia (CIA) is a common and emotionally-taxing side effect of chemotherapy, including taxane agents used frequently in treatment of gynecologic cancers. Scalp hypothermia, also known as "cold caps", is a possible method to prevent severe CIA, studied primarily in the breast cancer population. OBJECTIVES: To compile existing data on scalp hypothermia in cancer patients receiving taxane chemotherapy in order to investigate its application to the gynecologic cancer population. SEARCH STRATEGY: MEDLINE, Embase, CINAHL, ClinicalTrials.gov, and Cochrane were searched through January 31, 2023. SELECTION CRITERIA: Full-text manuscripts reporting on the results of scalp hypothermia in patients receiving taxane-based chemotherapy. DATA COLLECTION AND ANALYSIS: Binomial proportions were summed, and random-effects meta-analyses performed. MAIN RESULTS: From 1424 records, we included 31 studies, representing 14 different countries. Only 5 studies included gynecologic cancer patients. We extracted the outcome of the proportion of patients with <50% hair loss. Among 2179 included patients, 60.7% were reported to have <50% hair loss (meta-analysis: 60.6%, 95% confidence interval [CI] 54.9-66.1%). Among the 28 studies reporting only on taxane-based chemotherapy, the rate of <50% hair loss was 60.0% (meta-analysis: 60.9%, (95% CI: 54.9-66.7%). In comparative studies, hair loss was significantly less in patients who received scalp hypothermia versus those who did not (49.3% versus 0% with <50% hair loss; OR 40.3, 95% CI: 10.5-154.8). Scalp cooling achieved <50% hair loss in patients receiving paclitaxel (67.7%; meta-analysis 69.9%, 95% CI 64.1-75.4%) and docetaxel (57.1%; meta-analysis 60.5%, 95% CI 50.0-71.6%). Meta-analysis on patient satisfaction in regard to scalp cooling found a satisfaction rate of 78.9% (95% CI 69.1-87.4%). CONCLUSION: Scalp hypothermia may be an effective method to reduce some cases of CIA due to taxane chemotherapy, especially paclitaxel. More trials need to be done to determine the precise effects of scalp hypothermia in gynecologic cancer patients.
RESUMEN
The BRCA1-associated protein 1 ( BAP1 ) gene encodes a tumor suppressor that functions as a ubiquitin hydrolase involved in DNA damage repair. BAP1 germline mutations are associated with increased risk of multiple solid malignancies, including mesothelioma, uveal melanoma, renal cell carcinoma, and high-grade rhabdoid meningiomas. Here, we describe the case of a 52-yr-old woman who experienced multiple abdominal recurrences of an ovarian sex cord-stromal tumor that was originally diagnosed at age 25 and who was found to have a germline mutation in BAP1 and a family history consistent with BAP1 tumor predisposition syndrome. Recurrence of the sex cord-stromal tumor demonstrated loss of BAP1 expression by immunohistochemistry. Although ovarian sex cord-stromal tumors have been described in mouse models of BAP1 tumor predisposition syndrome, this relationship has not been previously described in humans and warrants further investigation. The case presentation, tumor morphology, and immunohistochemical findings have overlapping characteristics with peritoneal mesotheliomas, and this case represents a potential pitfall for surgical pathologists.

OBJECTIVES: To describe population rate of hysterectomy for benign disease in the USA, including geographic variation across states and Hospital Service Areas (HSAs; areas defined by common patient flows to healthcare facilities). DESIGN: Cross-sectional study. SETTING: Four US states including 322 HSAs. POPULATION: A total of 316 052 cases of hysterectomy from 2012 to 2016. METHODS: We compiled annual hysterectomy cases, merged female populations, and adjusted for reported rates of previous hysterectomy. We assessed small-area variation and created multi-level Poisson regression models. MAIN OUTCOME MEASURES: Prior-hysterectomy-adjusted population rates of hysterectomy for benign disease. RESULTS: The annual population rate of hysterectomy for benign disease was 49 per 10 000 hysterectomy-eligible residents, declining slightly over time, mostly among reproductive-age populations. Rates peaked among residents ages 40-49 years, and declined with increasing age, apart from an increase with universal coverage at age 65 years. We found large differences in age-standardised population rates of hysterectomy across states (range 42.2-69.0), and HSAs (range: overall 12.9-106.3; 25th-75th percentile 44.0-64.9). Among the non-elderly population, those with government-sponsored insurance had greater variation than those with private insurance (coefficient of variation 0.61 versus 0.32). Proportions of minimally invasive procedures were similar across states (71.0-74.8%) but varied greatly across HSAs (27-96%). In regression models, HSA population characteristics explained 31.8% of observed variation in annual rates. Higher local proportions of government-sponsored insurance and non-White race were associated with lower population rates. CONCLUSIONS: We found substantial variation in rate and route of hysterectomy for benign disease in the USA. Local population characteristics explained less than one-third of observed variation.

BACKGROUND: High-risk gestational trophoblastic neoplasia (GTN) is rare and treated with diverse approaches. Limited published institutional data has yet to be systematically reviewed. OBJECTIVES: To compile global high-risk GTN (prognostic score ≥7) cohorts to summarise treatments and outcomes by disease characteristics and primary chemotherapy. SEARCH STRATEGY: MEDLINE, Embase, Scopus, ClinicalTrials.gov and Cochrane were searched through March 2021. SELECTION CRITERIA: Full-text manuscripts reporting mortality among ≥10 high-risk GTN patients. DATA COLLECTION AND ANALYSIS: Binomial proportions were summed, and random-effects meta-analyses performed. MAIN RESULTS: From 1137 records, we included 35 studies, representing 20 countries. Among 2276 unique high-risk GTN patients, 99.7% received chemotherapy, 35.8% surgery and 4.9% radiation. Mortality was 10.9% (243/2236; meta-analysis: 10%, 95% confidence interval [CI] 7-12%) and likelihood of complete response to primary chemotherapy was 79.7% (1506/1890; meta-analysis: 78%, 95% CI: 74-83%). Across 24 reporting studies, modern preferred chemotherapy (EMA/CO or EMA/EP) was associated with lower mortality (overall: 8.8 versus 9.5%; comparative meta-analysis: 8.1 versus 12.4%, OR 0.42, 95% CI: 0.20-0.90%, 14 studies) and higher likelihood of complete response (overall: 76.6 versus 72.8%; comparative meta-analysis: 75.9 versus 60.7%, OR 2.98, 95% CI: 1.06-8.35%, 14 studies), though studies focused on non-preferred regimens reported comparable outcomes. Mortality was increased for ultra-high-risk disease (30 versus 7.5% high-risk; meta-analysis OR 7.44, 95% CI: 4.29-12.9%) and disease following term delivery (20.8 versus 7.3% following molar pregnancy; meta-analysis OR 2.64, 95% CI: 1.10-6.31%). Relapse rate estimates ranged from 3 to 6%. CONCLUSIONS: High-risk GTN is responsive to several chemotherapy regimens, with EMA/CO or EMA/EP associated with improved outcomes. Mortality is increased in patients with ultra-high-risk, relapsed and post-term pregnancy disease.

BACKGROUND: In recent years, the issue of out-of-network billing for privately insured patients has been highlighted as a source of unexpected out-of-pocket charges for patients, even in the setting of an in-network primary surgeon. The Congress recently passed the No Surprises Act to curtail these practices. However, the new law contains exceptions, and its regulatory system has yet to be established. As one of the most frequently performed major surgical procedures, hysterectomy represents a significant exposure to out-of-network bills among nonelderly females in the United States. OBJECTIVE: To describe the extent and nature of out-of-network bills at the time of hysterectomy among privately insured patients in the context of the recently passed No Surprises Act. STUDY DESIGN: We performed a retrospective cohort study of women aged 18 to 64 years who underwent simple hysterectomy from 2008 to 2018 with an in-network primary surgeon in the IBM Watson Marketscan claims database, which includes data from over 350 different payers. We identified out-of-network claims for facility or professional services and analyzed the frequency, size, and source of the payments. We used multivariable logistic regression to assess for patient, procedure, and facility characteristics associated with the risk of out-of-network claims. RESULTS: We identified 585,223 hysterectomy cases meeting all the inclusion criteria, and they were evenly split between inpatient (49.6%) and outpatient (50.4%) procedures. Overall, 8.8% of cases included at least 1 out-of-network claim, with median out-of-network expenditures of $553 for inpatient procedures and $438 for outpatient procedures. Compared with professional out-of-network claims, facility out-of-network claims were less common (2.3% vs 7.4%) but far greater in the amount billed (median $8,307 vs $400 inpatient, $3,281 vs $407 outpatient). Among the professional claims, those from midlevel surgical assistants were most frequently out-of-network when present (13.8% inpatient; 20.0% outpatient), whereas out-of-network claims from anesthesia were most common overall and largest (median $890 inpatient, $1,021 outpatient) when present. In a multivariable model, older age, increasing comorbidity, and complications during the stay were associated with higher odds of any out-of-network claim. In contrast, the risk of facility out-of-network claims was more strongly associated with the facility region and the surgical approach, with the highest odds for cases in the North Central region and those using robotic approach. CONCLUSION: Out-of-network bills for privately insured patients at the time of hysterectomy occurred in 8.8% of cases. Approximately one-quarter of these included out-of-network facility claims tended to have higher payments than out-of-network professional claims and may not be prevented by the No Surprises Act. Gynecologic surgeons should be aware of the potential out-of-network charges for ancillary services at the time of surgery, particularly the network status of the facility, to provide maximal transparency and financial protection to our patients.

BACKGROUND: In recent years, there has been growing recognition of the financial burden of severe illness, including associations with higher rates of nonemployment, uninsurance, and catastrophic out-of-pocket health spending. Patients with gynecologic cancer often require expensive and prolonged treatments, potentially disrupting employment and insurance coverage access, and putting patients and their families at risk for catastrophic health expenditures. OBJECTIVE: This study aimed to describe the prevalence of insurance churn, nonemployment, and catastrophic health expenditures among nonelderly patients with gynecologic cancer in the United States, to compare within subgroups and to other populations and assess for changes associated with the Affordable Care Act. STUDY DESIGN: We identified respondents aged 18 to 64 years from the Medical Expenditure Panel Survey, 2006 to 2017, who reported care related to gynecologic cancer in a given year, and a propensity-matched cohort of patients without cancer and patients with cancers of other sites, as comparison groups. We applied survey weights to extrapolate to the US population, and we described patterns of insurance churn (any uninsurance or insurance loss or change), catastrophic health expenditures (>10% annual family income), and nonemployment. Characteristics and outcomes between groups were compared with the adjusted Wald test. RESULTS: We identified 683 respondents reporting care related to a gynecologic cancer diagnosis from 2006 to 2017, representing an estimated annual population of 532,400 patients (95% confidence interval, 462,000-502,700). More than 64% of patients reported at least 1 of 3 primary negative outcomes of any uninsurance, part-year nonemployment, and catastrophic health expenditures, with 22.4% reporting at least 2 of 3 outcomes. Catastrophic health spending was uncommon without nonemployment or uninsurance reported during that year (1.2% of the population). Compared with patients with other cancers, patients with gynecologic cancer were younger and more likely with low education and low family income (≤250% federal poverty level). They reported higher annual risks of insurance loss (8.8% vs 4.8%; P=.03), any uninsurance (22.6% vs 14.0%; P=.002), and part-year nonemployment (55.3% vs 44.6%; P=.005) but similar risks of catastrophic spending (12.6% vs 12.2%; P=.84). Patients with gynecologic cancer from low-income families faced a higher risk of catastrophic expenditures than those of higher icomes (24.4% vs 2.9%; P<.001). Among the patients from low-income families, Medicaid coverage was associated with a lower risk of catastrophic spending than private insurance. After the Affordable Care Act implementation, we observed reductions in the risk of uninsurance, but there was no significant change in the risk of catastrophic spending among patients with gynecologic cancer. CONCLUSION: Patients with gynecologic cancer faced high risks of uninsurance, nonemployment, and catastrophic health expenditures, particularly among patients from low-income families. Catastrophic spending was uncommon in the absence of either nonemployment or uninsurance in a given year.

OBJECTIVE: Neoadjuvant chemotherapy (NACT) has emerged as an alternative to primary cytoreductive surgery (PCS) for stage IV uterine cancer. We examined utilization, perioperative outcomes and survival for NACT and PCS for stage IV uterine cancer. METHODS: The Surveillance, Epidemiology, End Results-Medicare database was used to identify women with stage IV uterine cancer treated from 2000 to 2015. Women were classified as NACT or PCS. Interval cytoreductive surgery (after NACT) or chemotherapy (after PCS) were recorded. The extent of surgery and perioperative outcomes were estimated for the groups. Multivariable proportional hazards models and Kaplan-Meier analyses were used to examine survival. RESULTS: Among 3037 women, 1629 (53.6%) were treated with primary cytoreductive surgery, 554 (18.2%) with NACT, and 854 (28.1%) received no treatment. Use of NACT increased from 9.5% to 29.2%. After NACT, interval hysterectomy was performed in 159 (28.6%), while within the PCS group, 1052 (64.6%) received chemotherapy. Extended cytoreductive procedures were performed in 71.7% of women who received NACT vs. 79.1% after PCS (P = 0.03). The complication rate was 52.8% for NACT versus 56.2% for PCS (P = 0.42); medical complications were more frequently seen in the PCS group (39.4% versus 28.9%; P = 0.01). There was no difference in cancer specific (P = 0.48) or overall survival (P = 0.25) in women who received both chemotherapy and surgery regardless of whether the initial treatment was NACT or PCS. CONCLUSION: Use of NACT is increasing for advanced stage uterine cancer. There was no difference in survival between NACT and primary cytoreductive surgery and NACT was associated with fewer perioperative medical complications.

BACKGROUND: Historically, published guidelines for care after molar pregnancy recommended monitoring human chorionic gonadotropin levels for the development of gestational trophoblastic neoplasia until normal and then for 6 months after the first normal human chorionic gonadotropin. However, there are little data underlying such recommendations, and recent evidence has demonstrated that gestational trophoblastic neoplasia diagnosis after human chorionic gonadotropin normalization is rare. OBJECTIVE: We sought to estimate the cost-effectiveness of alternative strategies for surveillance for gestational trophoblastic neoplasia after human chorionic gonadotropin normalization after complete and partial molar pregnancy. STUDY DESIGN: A Markov-based cost-effectiveness model, using monthly cycles and terminating after 36 months/cycles, was constructed to compare alternative strategies for asymptomatic human chorionic gonadotropin surveillance after the first normal (none; monthly testing for 1, 3, 6, and 12 months; or every 3-month testing for 3, 6, and 12 months) for both complete and partial molar pregnancy. The risk of reduced surveillance was modeled by increasing the probability of high-risk disease at diagnosis. Probabilities, costs, and utilities were estimated from peer-reviewed literature, with all cost data applicable to the United States and adjusted to 2020 US dollars. The primary outcome was cost per quality-adjusted life year ($/quality-adjusted life year) with a $100,000/quality-adjusted life year willingness-to-pay threshold. RESULTS: Under base-case assumptions, we found no further surveillance after the first normal human chorionic gonadotropin to be the dominant strategy from both the healthcare system and societal perspectives, for both complete and partial molar pregnancy. After complete mole, this strategy had the lowest average cost (healthcare system, $144 vs maximum $283; societal, $152 vs maximum $443) and highest effectiveness (2.711 vs minimum 2.682 quality-adjusted life years). This strategy led to a slightly higher rate of death from gestational trophoblastic neoplasia (0.013% vs minimum 0.009%), although with high costs per gestational trophoblastic neoplasia death avoided (range, $214,000 to >$4 million). Societal perspective costs of lost wages had a greater impact on frequent surveillance costs than rare gestational trophoblastic neoplasia treatment costs, and no further surveillance was more favorable from this perspective in otherwise identical analyses. No further surveillance remained dominant or preferred with incremental cost-effectiveness ratio of <$100,000 in all analyses for partial mole, and most sensitivity analyses for complete mole. Under the assumption of no disutility from surveillance, surveillance strategies were more effective (by quality-adjusted life year) than no further surveillance, and a single human chorionic gonadotropin test at 3 months was found to be cost-effective after complete mole with incremental cost-effectiveness ratio of $53,261 from the healthcare perspective, but not from the societal perspective (incremental cost-effectiveness ratio, $288,783). CONCLUSION: Largely owing to the rare incidence of gestational trophoblastic neoplasia after human chorionic gonadotropin normalization after molar pregnancy, prolonged surveillance is not cost-effective under most assumptions. It would be reasonable to reduce, and potentially eliminate, current recommendations for surveillance after human chorionic gonadotropin normalization after molar pregnancy, particularly among partial moles. With any reduction in surveillance, patients should be counseled on symptoms of gestational trophoblastic neoplasia and established in routine gynecologic care.

BACKGROUND: Women with gynecologic cancer face socioeconomic disparities in care that affect survival outcomes. The Affordable Care Act offered states the option to expand Medicaid enrollment eligibility criteria as a means of improving timely and affordable access to care for the most vulnerable. The variable uptake of expansion by states created a natural experiment, allowing for quasi-experimental methods that offer more unbiased estimates of treatment effects from retrospective data than the traditional regression adjustment. OBJECTIVE: To use a quasi-experimental, difference-in-difference framework to create unbiased estimates of impact of Medicaid expansion on women with gynecologic cancer. STUDY DESIGN: We performed a quasi-experimental retrospective cohort study from the National Cancer Database files for women with invasive cancers of the uterus, ovary and fallopian tube, cervix, vagina, and vulva diagnosed from 2008 to 2016. Using a marker for state Medicaid expansion status, we created difference-in-difference models to assess the impact of Medicaid expansion on the outcomes of access to and timeliness of care. We excluded women aged <40 years owing to the suppression of the state Medicaid expansions status in the data and women aged ≥65 years owing to the universal Medicare coverage availability. Our primary outcome was the rate of uninsurance at diagnosis. Secondary outcomes included Medicaid coverage, early-stage diagnosis, treatment at an academic facility, and any treatment or surgery within 30 days of diagnosis. Models were run within multiple subgroups and on a propensity-matched cohort to assess the robustness of the treatment estimates. The assumption of parallel trends was assessed with event study time plots. RESULTS: Our sample included 335,063 women. Among this cohort, 121,449 were from nonexpansion states and 213,614 were from expansion states, with 79,886 posttreatment cases diagnosed after the expansion took full effect in expansion states. The groups had minor differences in demographics, and we found occasional preperiod event study coefficients diverging from the mean, but the outcome trends were generally similar between the expansion and nonexpansion states in the preperiod, satisfying the necessary assumption for the difference-in-difference analysis. In a basic difference-in-difference model, the Medicaid expansion in January 2014 was associated with significant increases in insurance at diagnosis, treatment at an academic facility, and treatment within 30 days of diagnosis (P<.001 for all). In an adjusted model including all states and accounting for variable expansion implementation time, there was a significant treatment effect of Medicaid expansion on the reduction in uninsurance at diagnosis (-2.00%; 95% confidence interval, -2.3 to -1.7; P<.001), increases in early-stage diagnosis (0.80%; 95% confidence interval, 0.2-1.4; P=.02), treatment at an academic facility (0.83%; 95% confidence interval, 0.1-1.5; P=.02), treatment within 30 days (1.62%; 95% confidence interval, 1.0-2.3; P<.001), and surgery within 30 days (1.54%; 95% confidence interval, 0.8-2.3; P<.001). In particular, large gains were estimated for women living in low-income zip codes, Hispanic women, and women with cervical cancer. Estimates from the subgroup and propensity-matched cohorts were generally consistent for all outcomes besides early-stage diagnosis and treatment within 30 days. CONCLUSION: Medicaid expansion was significantly associated with gains in the access and timeliness of treatment for nonelderly women with gynecologic cancer. The implementation of Medicaid expansion could greatly benefit women in nonexpansion states. Gynecologists and gynecologic oncologists should advocate for Medicaid expansion as a means of improving outcomes and reducing socioeconomic and racial disparities.

OBJECTIVE: Endometrial cancer uncommonly presents at an advanced stage and little prospective evidence exists to guide the management thereof. We aimed to summarize the evidence about primary cytoreductive surgery in the treatment of advanced stage endometrial cancer. DATA SOURCES: MEDLINE, Embase, and Scopus databases were searched from inception to September 11, 2020, using search terms representing the themes "endometrial cancer," "advanced stage," and "primary cytoreductive surgery." STUDY ELIGIBILITY CRITERIA: We included full-text, English reports that included ≥10 patients undergoing primary cytoreductive surgery for advanced stage endometrial cancer and that reported on the outcomes of primary cytoreductive surgery and survival rates based on the residual disease burden. METHODS: Two reviewers independently screened the studies and with disagreements between the reviewers resolved by a third reviewer. Data were extracted using a standardized form. The percentage of cases reaching maximal (no gross residual disease) and optimal (<1 cm or <2 cm residual disease) cytoreduction were assessed by summing binomials proportions, and the association with survival was assessed using an inverse variance-weighted meta-analysis of logarithmic hazard ratios. RESULTS: From 1219 unique records identified, 34 studies were selected for inclusion. Studies consisted of single or multi-institutional cohorts of patients collected over a period of 6 to 24 years and included various mixes of histologies (endometrioid, serous, clear cell, and carcinosarcoma) and disease stages (III or IV). In a meta-analysis of the extent of residual disease after primary cytoreductive surgery, we found that 52.1% of cases reached no gross residual disease status (n=18 studies; 1329 patients) and 75% reached <1 cm residual disease status (n=27 studies; 2343 patients). The proportion of cytoreduction for both thresholds was lower for studies of stage IV vs stage III to IV disease (41.4% vs 69.8% for no gross residual disease; 63.2% vs 82.2% for <1 cm residual disease) but did not vary notably by histology. In a meta-analysis of the reported hazard ratios, submaximal (any gross residual disease vs no gross residual disease) and suboptimal (≥1 cm vs <1 cm) cytoreduction thresholds were associated with worse progression-free survival (submaximal hazard ratio, 2.16; 95% confidence interval, 1.45-3.21; I2=68%; suboptimal hazard ratio, 2.55; 95% confidence interval, 1.93-3.37; I2=63%) and overall survival rates (submaximal hazard ratio, 2.57; 95% confidence interval, 2.13-3.10; I2=1%; suboptimal hazard ratio, 2.62; 95% confidence interval, 2.20-3.11; I2=15%). Sensitivity analyses limited to high-quality studies demonstrated consistent results. CONCLUSION: Among cases of advanced stage endometrial cancer undergoing primary cytoreductive surgery, a significant proportion of patients are left with residual disease, which is associated with worse survival outcomes. Further investigations about the roles of neoadjuvant chemotherapy and primary cytoreductive surgery in prospective trials is warranted in this population.

OBJECTIVE: The role and type of adjuvant therapy for patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIIA grade 1 endometrioid endometrial adenocarcinoma are controversial. This retrospective cohort study aimed to determine associations between adjuvant therapy use and survival among patients with stage IIIA grade 1 endometrial cancer. METHODS: Patients who underwent primary surgery for stage IIIA (FIGO 2009 staging) grade 1 endometrial cancer between January 2004 and December 2016 were identified in the National Cancer Database. Demographics and receipt of adjuvant therapy were compared. Overall survival was analyzed using Kaplan-Meier curves, log-rank test, and multivariable Cox proportional hazard models. RESULTS: Of 1120 patients, 248 (22.1%) received no adjuvant treatment, 286 (25.5%) received chemotherapy alone, 201 (18.0%) radiation alone, and 385 (34.4%) chemotherapy and radiation. Five-year overall survival rate was 83.0% (95% CI 80.1% to 85.6%). Older age, increasing comorbidity count, and lymphovascular space invasion status were significant negative predictors of survival. Over time, there was an increasing rate of chemotherapy (45.4% in 2004-2009 vs 69.2% in 2010-2016; p<0.001). In the multivariable analysis, chemotherapy was associated with significantly improved overall survival compared with no adjuvant therapy (HR 0.49 (95% CI 0.31 to 0.79); p=0.003). There was no survival association when comparing radiation alone with no treatment, and none when adding radiation to chemotherapy compared with chemotherapy alone. Those with lymphovascular space invasion (n=124/507) had improved overall survival with chemotherapy and radiation (5-year overall survival 91.2% vs 76.7% for chemotherapy alone and 27.3% for radiation alone, log-rank p<0.001), but there was no survival difference after adjusting for age and comorbidity (HR 0.25 (95% CI 0.05 to 1.41); p=0.12). CONCLUSIONS: The use of adjuvant chemotherapy for the treatment of stage IIIA grade 1 endometrial cancer increased over time and was associated with improved overall survival compared with radiation alone or chemoradiation.

INTRODUCTION: Payment reform will give oncologists increasing responsibility for how patients with cancer meet unexpected care needs. OBJECTIVE: To differentiate how patients with gynecologic cancers use emergency care, and to assess the characteristics associated with potentially avoidable treat-and-release visits. METHODS: We performed a retrospective cohort study using the Nationwide Emergency Department Sample, a stratified sample of visits in United States hospital-based emergency departments, from 2010 to 2014. Visits by patients with a diagnosis of gynecologic cancer were selected. Sample weights were applied to calculate national estimates of care patterns and trends. Associations with treat-and-release disposition were assessed with weighted logistic regression. RESULTS: In the study period, patients with gynecologic cancer made an estimated 370 104 annual emergency department visits (95% CI 351 997 to 388 211). A total of 50.2% of patients were treated and released, 48% were admitted, 1.6% were transferred, and 0.1% died. These visits corresponded to over US$1.27 billion in annual charges, with an average charge of US$3428 per visit (95% CI 3348 to 3509). Driven by growing treat-and-release utilization, annual visits increased, while admission rates fell over time. Patients with cervical cancer represented the plurality (36%) of visits; they were relatively younger, of lower socioeconomic status, and had fewer co-morbidities. Models for treat-and-release disposition did not vary significantly across different cancer populations. In the all-cancer model, increased odds of treat-and-release disposition was associated with cervical cancer diagnosis, younger age, lesser Elixhauser co-morbidity, Medicare coverage (OR=1.19; p<0.001), Medicaid coverage (OR=1.25; p<0.001), uninsured status (OR=1.70; p<0.001), and weekend visits. Visits in the northeast, at urban hospitals, and in winter months showed decreased odds of treat-and-release disposition. DISCUSSION: Patients with gynecologic cancers have been using the emergency department at increasing rates, primarily driven by treat-and-release visits that did not result in admission or death. Patients with cervical cancer have higher rates of treat-and-release utilization and may over-use emergency department care.

OBJECTIVE: To investigate the oncologic outcomes of patients with early-stage cervical carcinoma and tumor size <2 cm who underwent open or minimally invasive radical hysterectomy. METHODS: The Pubmed/Medline, Embase, and Web-of-Science databases were queried from inception to January 2021 (PROSPERO CRD 42020207971). Observational studies reporting progression-free survival and/or overall survival for patients who had open or minimally invasive radical hysterectomy for early-stage cervical carcinoma and tumor size <2 cm were selected. Level of statistical heterogeneity was evaluated with the I2 statistic. A random-effects model was used to compare progression and overall survival between the two groups and HR with 95% confidence intervals were calculated with the Der Simonian and Laird approach. Risk of bias and quality of included studies was assessed with the Newcastle-Ottawa scale. RESULTS: A total of 10 studies that met the inclusion criteria were included encompassing 4935 patients. Of these, 2394 (48.5%) patients had minimally invasive and 2541 (51.5%) patients had open radical hysterectomy; respectively. Patients who underwent minimally invasive hysterectomy had worse progression-free survival than those who had open surgery (HR 1.68, 95% CI 1.20, 2.36, I2 26%). Based on five studies, patients who had minimally invasive (n=1808) hysterectomy had a trend towards worse overall survival than those who had open surgery (n=1853) (HR 1.64, 95% CI 1.00 to 2.68, I2 15%). CONCLUSION: Based on a systematic review of the literature and meta-analysis of studies that control for confounders, for patients with cervical cancer and tumor size <2 cm, minimally invasive radical hysterectomy was associated with worse progression-free survival than laparotomy.

OBJECTIVE: To assess the emergence of sentinel lymph node biopsy (SLNB) for disparities in utilization, and impacts on perioperative outcomes. METHODS: Retrospective cohort study of the National Cancer Database, selecting for patients with T1NxM0 endometrial cancer undergoing minimally invasive surgical staging from 2012 to 2016. Disparities in SLNB utilization were described. Propensity matching was performed. Association of SLNB with perioperative outcomes was assessed with logistic regression. RESULTS: Among 67,365 patients, 6356 (9.4%) underwent SLNB, increasing from 2.8% to 16.3% from 2012 to 2016. Disparities were identified within race (7.0% Black, 9.4% non-Black), ethnicity (8.3% Hispanic, 9.5% non-Hispanic), insurance (6.0% uninsured, 9.5% insured), county density (3.7% rural, 9.8% metro), and income (7.0% bottom-quartile, 11.8% top-quartile). Risk of conversion to open surgery was lower with SLNB alone (1.03%) or SLNB followed by LND (1.40%), versus upfront LND (2.80%). SLNB was associated with reduced risk of conversion to open surgery in Intention-To-Treat (SLNB+/-LND vs. upfront LND; ORITTâ¯=â¯0.53; 95%CI 0.39-0.72) and Per-Protocol (PP; SLNB alone vs. upfront LND or SLNB+LND; ORPPâ¯=â¯0.49; 95%CI 0.32-0.75) comparisons. SLNB was also associated with lower risk of length of stay >1â¯day (overall rate 6.3%; ORITTâ¯=â¯0.51; 95%CI 0.40-0.64; ORPPâ¯=â¯0.39; 95%CI 0.28-0.55), and unplanned readmission (overall rate 2.3%; ORPPâ¯=â¯0.52; 95%CI 0.33-0.81). There were no deaths within 90â¯days among 1370 SLNB alone cases, versus 2/1294 (0.15%) for SLNB+LND, and 123/28,828 (0.41%) for upfront LND. CONCLUSION: We identified significant disparities in the utilization of SLNB, as well as evidence that this less-invasive technique is associated with lower rates of certain perioperative complications. Equitable access to this emerging technique could lessen disparate outcomes.

OBJECTIVE: To evaluate factors associated with survival of patients with advanced stage mucinous ovarian carcinoma (MOC) using a large multi-institutional database. METHODS: Patients diagnosed between 2004 and 2014 with advanced stage (III-IV) MOC were identified within the National Cancer Database. Those without a personal history of another primary tumor who received cancer-directed surgery with a curative intent were selected for further analysis. Overall survival (OS) was evaluated with Kaplan-Meier curves, and compared with the log-rank test. Multivariate Cox analysis was performed to identify independent predictors of survival. RESULTS: A total of 1509 patients with a median age of 59 years (IQR 20) met the inclusion criteria: stage III (n = 1045, 69.3%) and stage IV disease (n = 464, 30.7%). Patients who received chemotherapy (n = 1065, 70.6%) had better OS compared to those who did not (n = 385, 25.5%), (median OS 15.44 vs 5.06 months, p < 0.001). The type of reporting facility (p = 0.65) and the year of diagnosis (p = 0.27) were not associated with OS. Presence of residual disease was strongly associated with OS (p < 0.001). After controlling for confounders, the administration of chemotherapy (HR 0.63, 95% CI 0.55, 0.72) was associated with better survival. CONCLUSION: Advanced stage MOC has an extremely poor prognosis. Patients who received chemotherapy had a small improvement in survival. Every effort to achieve complete gross resection should be performed. Given no improvement in survival outcomes over time, there is an eminent need for novel treatment options.

AIMS: To compare baseline risk factors for type 1 vs. 2 endometrial cancers and analyze these risk factors for association with overall survival and time to recurrence. METHODS: Retrospective review of 816 consecutive endometrial cancer cases was conducted with diagnosis from January 2005 to December 2010 and clinical course until 2016. Risk factors, treatment, recurrence, and death were compared using 2 sample t tests, χ2 test and Cox Regression models. RESULTS: There were 550 cases of type 1 and 266 cases of type 2 cancer. Patients with type 2 disease were older (p < 0.001), less obese (p = 0.03), non-white (p < 0.001), and menopausal (p = 0.02). There was no difference in use of oral contraceptives, hormone replacement therapy (HRT), smoking, or major cardiovascular disease. Cox Regression models showed that type 2 disease (p < 0.001) and advanced stage (p = 0.001) were associated with recurrence. CONCLUSIONS: Consistent with previous literature, our analysis found that type 2 cancer is more common in non-white, older, and less obese patients and associated with higher mortality and recurrence. However, inconsistent with previous literature, we found no association between type 2 cancer and diabetes mellitus or use of HRT. These factors should be considered when approaching patients with endometrial cancer.

OBJECTIVE: The aim of this study was to investigate the patterns of use and outcomes of adjuvant chemotherapy for patients diagnosed with FIGO stage I ovarian clear cell carcinoma (OCCC). METHODS: A cohort of patients diagnosed between 2004 and 2015 with OCCC was drawn from the National Cancer Database. Those with stage I disease who had primary surgery and underwent systematic lymphadenectomy (defined as at least 10 lymph nodes removed) were selected for further analysis. Factors associated with the administration of adjuvant chemotherapy were investigated with multivariate logistic regression. Overall survival (OS) was evaluated using Kaplan-Meier curves for patients diagnosed between 2004 and 2014, while comparisons were made with the log-rank test. Multivariate Cox analysis was performed to control for possible confounders. RESULTS: A total of 2325 patients met the inclusion criteria. Median age was 55â¯years. The majority were White (86.6%). Adjuvant chemotherapy was administered to 1839 (79.1%) patients. Hospital type and location, patient age, disease sub-stage, and year of diagnosis were independently associated with the administration of chemotherapy. Patients who received adjuvant chemotherapy (nâ¯=â¯1629) had better OS than those who did not (nâ¯=â¯443), (5-year OS rates 89.2% vs 82.6%, pâ¯<â¯0.001). After controlling for disease sub-stage, age, race, hospital type and medical comorbidities, adjuvant chemotherapy was associated with better overall survival (HR: 0.59, 95% CI: 0.45, 0.78). CONCLUSIONS: Adjuvant chemotherapy could be associated with a survival benefit for patients with stage I OCCC.

BACKGROUND: Appendectomy is the most common emergency surgery performed in the USA. Removal of a non-inflamed appendix during unrelated abdominal surgery (prophylactic or incidental appendectomy) can prevent the downstream risks and costs of appendicitis. It is unknown whether such a strategy could be cost saving for the health system. METHODS: We considered hypothetical patient cohorts of varying ages from 18 to 80, undergoing elective laparoscopic abdominal and pelvic procedures. A Markov decision model using cost per life-year as the main outcome measure was constructed to simulate the trade-off between cost and risk of prophylactic appendectomy and the ongoing risk of developing appendicitis, with downstream costs and risks. Rates, probabilities, and costs of disease, treatment, and outcomes by patient age and gender were extracted from the literature. Sensitivity analyses were conducted using complications and costs of prophylactic appendectomy. RESULTS: With our base-case assumptions, including added cost of prophylactic appendectomy of $660, we find that prophylactic removal of the appendix is cost saving for males aged 18-27 and females aged 18-28 undergoing elective surgery. The margin of cost savings depends on remaining life-years and increases exponentially with age: a 20-year-old female undergoing elective surgery could save $130 over a lifetime by undergoing prophylactic appendectomy, while a 40-year-old female would lose $130 over a lifetime. When the risk of the prophylactic appendectomy exceeds the risk of laparoscopic appendectomy for appendicitis or the cost exceeds $1080, it becomes more cost saving to forego the prophylactic procedure. CONCLUSIONS: Prophylactic appendectomy can be cost saving for patients younger than age thirty undergoing elective laparoscopic abdominal and pelvic procedures.

BACKGROUND: Accountable Care Organizations (ACOs) are a delivery and payment model aiming to coordinate care, control costs, and improve quality. Medicare ACOs are responsible for 8 measures of preventive care quality. OBJECTIVES: To create composite measures of preventive care quality and examine associations of ACO characteristics with performance. DESIGN: This is a cross-sectional study of Medicare Shared Savings Program and Pioneer participants. We linked quality performance to descriptive data from the National Survey of ACOs. We created composite measures using exploratory factor analysis, and used regression to assess associations with organizational characteristics. RESULTS: Of 252 eligible ACOs, 246 reported on preventive care quality, 177 of which completed the survey (response rate=72%). In their first year, ACOs lagged behind PPO performance on the majority of comparable measures. We identified 2 underlying factors among 8 measures and created composites for each: disease prevention, driven by vaccines and cancer screenings, and wellness screening, driven by annual health screenings. Participation in the Advanced Payment Model, having fewer specialists, and having more Medicare ACO beneficiaries per primary care provider were associated with significantly better performance on both composites. Better performance on disease prevention was also associated with inclusion of a hospital, greater electronic health record capabilities, a larger primary care workforce, and fewer minority beneficiaries. CONCLUSIONS: ACO preventive care quality performance is related to provider composition and benefitted by upfront investment. Vaccine and cancer screening quality performance is more dependent on organizational structure and characteristics than performance on annual wellness screenings, likely due to greater complexity in eligibility determination and service administration.
