RESUMEN

Many cells undergo symmetry-breaking polarization toward a randomly oriented "front" in the absence of spatial cues. In budding yeast, such polarization involves a positive feedback loop that enables amplification of stochastically arising clusters of polarity factors. Previous mathematical modeling suggested that, if more than one cluster were amplified, the clusters would compete for limiting resources and the largest would "win," explaining why yeast cells always make one and only one bud. Here, using imaging with improved spatiotemporal resolution, we show the transient coexistence of multiple clusters during polarity establishment, as predicted by the model. Unexpectedly, we also find that initial polarity factor clustering is oscillatory, revealing the presence of a negative feedback loop that disperses the factors. Mathematical modeling predicts that negative feedback would confer robustness to the polarity circuit and make the kinetics of competition between polarity factor clusters relatively insensitive to polarity factor concentration. These predictions are confirmed experimentally.

RESUMEN

BACKGROUND: Cervical cancer incidence among premenopausal women is rising, and fertility-sparing surgery serves as an important option for this young population. There is a lack of evidence on what tumor size cutoff should be used to define candidacy for fertility-sparing surgery. OBJECTIVE: We sought to describe how the association between fertility-sparing surgery (compared with standard surgery) and life expectancy varies by tumor size among patients with cervical cancers measuring ≤4 cm in largest diameter. Our secondary objective was to quantify the probability of undergoing adjuvant radiotherapy among patients who underwent fertility-sparing surgery as a function of tumor size. STUDY DESIGN: We identified patients in the National Cancer Database aged ≤45 years, diagnosed with stage I cervical cancer with tumors ≤4 cm between 2006 and 2018, who received no preoperative radiation or chemotherapy, and who underwent either fertility-sparing surgery (cone or trachelectomy, either simple or radical) or standard surgery (simple or radical hysterectomy) as their primary treatment. Propensity-score matching was performed to compare patients who underwent fertility-sparing surgery with those who underwent standard surgery. A flexible parametric model was employed to quantify the difference in life expectancy within 5 years of diagnosis (restricted mean survival time) based on tumor size among patients who underwent fertility-sparing and those who underwent standard surgery. In addition, among those who underwent fertility-sparing surgery, a logistic regression model was used to explore the relationship between tumor size and the probability of receiving adjuvant radiation. RESULTS: A total of 11,946 patients met the inclusion criteria of whom 904 (7.6%) underwent fertility-sparing surgery. After propensity-score matching, 897 patients who underwent fertility-sparing surgery were matched 1:1 with those who underwent standard surgery. Although the 5-year life expectancy was similar among patients who had fertility sparing surgery and those who had standard surgery regardless of tumor sizes, the estimates of life-expectancy differences associated with fertility-sparing surgery were more precise among patients with smaller tumors (1-cm tumor: restricted mean survival time difference, -0.10 months; 95% confidence interval, -0.67 to 0.47) than among those with larger tumors (4-cm tumor: restricted mean survival time difference, -0.11 months; 95% confidence interval, -3.79 to 3.57). The probability of receiving adjuvant radiation increased with tumor size, ranging from 5.6% (95% confidence interval, 3.9-7.9) for a 1-cm tumor to 37% (95% confidence interval, 24.3-51.8) for a 4-cm tumor. CONCLUSION: Within 5 years of diagnosis, young patients with stage I cancers measuring ≤4 cm had similar survival outcomes after either fertility-sparing surgery or standard surgery. However, because few patients with tumors >2 cm underwent fertility-sparing surgery, a clinically important survival difference could not be excluded in this population.

RESUMEN

OBJECTIVE: Patients with intermediate-risk cervical cancer receive external beam radiotherapy (EBRT) as adjuvant treatment. It is commonly administered with brachytherapy without proven benefits. Therefore, we evaluated the frequency of brachytherapy use, the doses for EBRT administered alone or with brachytherapy, and the overall survival impact of brachytherapy in patients with intermediate-risk, early-stage cervical cancer. METHODS: This retrospective cohort study was performed using data collected from the National Cancer Database. Patients diagnosed with cervical cancer from 2004 to 2019 who underwent a radical hysterectomy and lymph node staging and had disease limited to the cervix but with tumors larger than 4 cm or ranging from 2 to 4 cm with lymphovascular space invasion (LVSI) were included. Patients with distant metastasis or parametrial involvement were excluded. Patients who underwent EBRT alone were compared with those who also received brachytherapy after 2:1 propensity score matching. RESULTS: In total, 1174 patients met the inclusion criteria, and 26.7% of them received brachytherapy. After 2:1 propensity score matching, we included 620 patients in the EBRT group and 312 in the combination treatment group. Patients who received brachytherapy had higher equivalent doses than those only receiving EBRT. Overall survival did not differ between the two groups (hazard ratio (HR) 0.88 (95% confidence interval (CI), 0.62 to 1.23]; p=0.45). After stratification according to tumor histology, LVSI, and surgical approach, brachytherapy was not associated with improved overall survival. However, in patients who did not receive concomitant chemotherapy, the overall survival rate for those receiving EBRT and brachytherapy was significantly higher than that for those receiving EBRT alone (HR, 0.48 (95% CI, 0.27 to 0.86]; p=0.011). CONCLUSION: About one-fourth of the study patients received brachytherapy and EBRT. The variability in the doses and radiotherapy techniques used highlights treatment heterogeneity. Overall survival did not differ for EBRT with and without brachytherapy. However, overall survival was longer for patients who received brachytherapy but did not receive concomitant chemotherapy.

RESUMEN

PURPOSE: Equitable access to oncofertility services is a key component of cancer survivorship care, but factors affecting access and use remain understudied. METHODS: To describe disparities in assisted reproductive technology (ART) use among women with breast cancer in California, we conducted a population-based cohort study using linked oncology, ART, and demographic data. We identified women age 18-45 years diagnosed with invasive breast cancer between 2000 and 2015. The primary outcome was ART use-including oocyte/embryo cryopreservation or embryo transfer-after cancer diagnosis. We used log-binomial regression to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs) to identify factors associated with ART use. RESULTS: Among 36,468 women with invasive breast cancer, 206 (0.56%) used ART. Women significantly less likely to use ART were age 36-45 years at diagnosis (vs. 18-35 years: PR = 0.17, 95% CI 0.13-0.22); non-Hispanic Black or Hispanic (vs. non-Hispanic White: PR = 0.31, 95% CI 0.21-0.46); had at least one child (vs. no children: adjusted PR [aPR] = 0.39, 95% CI 0.25-0.60); or lived in non-urban areas (vs. urban: aPR = 0.28, 95% CI 0.10-0.75), whereas women more likely to use ART lived in high-SES areas (vs. low-/middle-SES areas: aPR = 2.93, 95% CI 2.04-4.20) or had private insurance (vs. public/other insurance: aPR = 2.95, 95% CI 1.59-5.49). CONCLUSION: Women with breast cancer who are socially or economically disadvantaged, or who already had a child, are substantially less likely to use ART after diagnosis. The implementation of policies or programs targeting more equitable access to fertility services for women with cancer is warranted.

RESUMEN

OBJECTIVE: To compare all-cause and cancer-specific mortality between women who underwent fertility-sparing surgery (FSS) versus standard surgery for stage IA and IC epithelial ovarian cancer. METHODS: Reproductive aged patients (18-45) with stage IA or IC epithelial ovarian cancer diagnosed between 2000 and 2015 were identified in the California Cancer Registry. FSS was defined as retention of the contralateral ovary and the uterus, and standard surgery included at least removal of both ovaries and the uterus. The primary outcome was all-cause mortality and the secondary outcome was cancer-specific mortality. Inverse probability of treatment weighting (IPTW) was used to create two groups balanced on covariates of interest. The Kaplan-Meier method and Cox proportional hazards analysis were used to model survival outcomes. RESULTS: Among 1119 women who met inclusion criteria, 390 (34.9%) underwent FSS. IPTW yielded a balanced cohort of 394 women who underwent FSS and 723 women who underwent standard surgery. Among patients who underwent FSS, there were 45 deaths corresponding to an 85.4% (95% confidence interval [CI] 0.79-0.92) 10-year all-cause survival probability, compared to 81 deaths and 86.4% 10-year all-cause survival probability (95% CI 0.83-0.90) among patients who underwent standard surgery. FSS was not associated with increased all-cause mortality (HR 1.04, 95% CI 0.72-1.49) or cancer-specific mortality (HR 1.50, 95%CI 0.97-2.31). CONCLUSIONS: Among reproductive-aged patients with early-stage epithelial ovarian cancer fertility-sparing surgery was not associated with an increased risk of death compared to standard surgery.

RESUMEN

OBJECTIVE: Assess outcomes of interval debulking surgery (IDS) after neoadjuvant chemotherapy via minimally invasive surgery (MIS) compared with laparotomy in patients with advanced epithelial ovarian cancer. METHODS: Patients diagnosed with stage IIIC or IV epithelial ovarian cancer between 2013 and 2018 who received neoadjuvant chemotherapy and IDS were identified in the National Cancer Database. Primary outcome was overall survival. Secondary outcomes were 5-year survival, 30- and 90-day postoperative mortality, extent of surgery, residual disease, hospitalization duration, surgical conversions, and unplanned readmissions. Propensity score matching was used to compare MIS and laparotomy for IDS. Association of treatment approach with overall survival was assessed using Kaplan-Meier method and Cox regression. Sensitivity analysis was conducted for effect of unmeasured confounders. RESULTS: A total of 7897 patients met inclusion criteria; 2021 (25.6%) underwent MIS. Percentage undergoing MIS increased from 20.3%-29.0% over the study period. After propensity score matching, median overall survival was 46.7 months in the MIS group versus 41.0 months in the laparotomy group [hazard ratio (HR) 0.86 (95%CI 0.79-0.94)]. Five-year survival probability was higher in MIS versus laparotomy (38.3% vs 34.8%, p < 0.01). There was lower 30- and 90-day mortality (0.3% vs 0.7% [p = 0.04] and 1.4% vs 2.5% [p = 0.01], respectively), shorter length of stay (median 3 vs 5 days, p < 0.01), lower residual disease (23.9% vs 26.7%, p < 0.01), and lower additional cytoreductive procedures (59.3% vs 70.8%, p < 0.01) in MIS compared to laparotomy, with similar rates of unplanned readmission (2.7% vs 3.1%, p = 0.39). CONCLUSIONS: Patients who undergo IDS by MIS have similar overall survival and decreased morbidity compared with laparotomy.

RESUMEN

OBJECTIVE: To assess the diagnostic accuracy of intraoperative SLN frozen section analysis compared with ultrastaging in patients with early-stage cervical cancer. METHODS: A systematic literature review was conducted following the PRISMA checklist. MEDLINE (via Ovid), Embase, and the Cochrane Central Register of Controlled Trials were searched from inception until February 2023. The inclusion criteria were patients with early-stage cervical cancer (2018 FIGO stage I-II), consisting of the histological subtype squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma (≥90% of the patients in each study), who underwent SLN detection (with any tracer) and intraoperative frozen section followed by SLN ultrastaging. Randomized controlled trials, prospective and retrospective observational studies were considered. The detection rates and measures of diagnostic accuracy were pooled using a random effects univariate model. A preplanned subgroup meta-analysis was conducted, with isolated tumor cells excluded as positive lymph nodes. The review was registered in PROSPERO (CRD42023397147). RESULTS: The search identified 190 articles, with 153 studies considered potentially eligible after removing duplicates. Fourteen studies met the selection criteria, including a total of 1720 patients. Seven studies were retrospective, and the other seven were prospective. Frozen section analysis detected 159 of 292 (54.5%) patients with lymph node metastases. In 281 patients the type of volume metastasis was reported: 1 of 41 (2.4%) patients had isolated tumor cells, 21 of 78 (26.9%) patients had micrometastases, and 133 of 162 (82.1%) patients had macrometastases. The pooled sensitivity of intraoperative SLN frozen section analysis was 65% (95% CI, 51-77%) for macrometastases, micrometastases, and isolated tumor cells. When we excluded patients with isolated tumor cells, the pooled sensitivity increased to 72% (95% CI, 60-82%). CONCLUSION: SLN frozen section detects 65% of lymph node metastases compared with SLN ultrastaging and may prevent unnecessary radical surgery in some patients with early-stage cervical cancer.

RESUMEN

The Centers for Disease Control and Prevention (CDC) promotes taking a 'bundling approach' (i.e., administering Tetanus, diphtheria toxoids, and acellular pertussis [Tdap] and human papillomavirus [HPV] vaccines in the same way and on the same day) for adolescent vaccinations. Recent trends and patterns in Tdap-HPV vaccination bundling in the USA remain undocumented. In addition, the implications of bundling Tdap-HPV vaccination for HPV vaccine series completion remain unknown. To address these critical knowledge gaps, we performed a retrospective study using a nationwide sample of privately insured adolescents (Optum's de-identified Clinformatics® Data Mart Database). Tdap-HPV vaccination bundling (per 100 Tdap vaccination encounters) during 2014-2018 was estimated overall, for 50 states, and by adolescents' age, sex, and provider specialties. Survival model estimated the likelihood of series completion among 9-14-year-old adolescents. From 2014 to 2018, 560,806 adolescents received a Tdap vaccine of which 172,604 (30.8%) received the HPV vaccines on the same day. Tdap-HPV vaccination bundling (per 100 Tdap vaccinations) increased nationally, from 22.9 in 2014 to 39.1 in 2018 (Ptrend < 0.001); bundling was lowest in New York and New Jersey. The likelihood of receiving the Tdap and HPV vaccines bundled was higher for young and female adolescents. Adolescents who received their first HPV vaccine bundled with the Tdap vaccine were more likely to complete the series compared to those who received it alone (Hazards Ratio = 1.45; 1.43-1.48). HPV vaccination bundling has increased in recent years in the USA. The increased likelihood of HPV vaccine series completion provides important evidence supporting the adoption of same-day Tdap-HPV vaccine administration in clinical practice to boost HPV vaccination coverage.

RESUMEN

OBJECTIVE: To estimate the average medical costs for vaginal and vulvar cancers in a commercially insured population in the U.S. and Texas. METHODS: 2011-2014U.S. MarketScan databases were used to estimate the average medical costs associated with vaginal and vulvar cancers. Women with newly diagnosed vaginal or vulvar cancer were matched to a comparison group without cancer using propensity score. Year 1 and year 2 costs after index diagnosis date were estimated. A generalized linear model was used to estimate the cost for censored months. The differential costs between groups were defined as the net costs associated with cancer diagnosis and treatment. RESULTS: The analysis included 355 women with vaginal cancer and 997 with vulvar cancer in the U.S. The year 1 and year 2 costs for vaginal cancer were $86,995 and $51,107, respectively. The year 1 and year 2 costs for vulvar cancer were $37,657 and $19,139, respectively. The major factors associated with higher monthly vaginal and vulvar cancer costs were higher Charlson Comorbidity Index score and higher medical costs prior to cancer diagnosis. Monthly costs for vaginal and vulvar cancers decreased rapidly from month 1 to month 6 after diagnosis and then remained stable. CONCLUSIONS: Seventy to 75% of all vaginal and vulvar cancers are due to HPV infections and mean medical costs associated with these cancers are substantial. These data will serve as key cost parameters in the economic evaluation of HPV vaccination dissemination and estimation of the long-term net economic benefit of promoting HPV vaccination.

RESUMEN

Using a national sample of single mothers from the 2007 and 2009 waves of the Panel Study of Income Dynamics, this study examined the effects of multiple employment statuses on the selfrated health of single mothers during the recent economic recession. Unlike other studies, the current study minimized selection bias by controlling for prior self-rated health, in addition to other predisposing factors, enabling factors, and need factors. We found that underemployment, but not unemployment, is associated with lower levels of self-rated health of single mothers. Results further indicate that the 25-39 age range (compared to the 18-24 age range), lower family income, prior lower self-rated health, more chronic diseases, and binge drinking place single mothers at an increased risk of lower levels of self-rated health. In contrast, strength-building physical activity is significantly associated with higher levels of self-rated health. Implications for health care policy and social work practice are drawn from the results.

RESUMEN

While empirical studies have observed that homeownership is associated with improved mental health conditions, research indicates that this relationship might vary by race. Moreover, such a White-Black disparity in the impacts of homeownership on mental health could be complexed by poverty status, as maintaining one's homeownership could be a financial burden for people living in poverty status, defined by the US official poverty threshold. We add to the existing literature by analyzing the impacts of homeownership on psychological distress, simultaneously disaggregating by race and poverty status using survey data from the Panel Study on Income Dynamics from the 2017 and 2019 waves (N = 7059). Propensity score weighting and doubly robust estimation are applied to estimate causal inference for the impact of 2017 homeownership on 2019 psychological distress using negative binomial models. First, we found the impacts of homeownership on reducing psychological distress are significant for White Americans, not for Black Americans. Second, we found such a White-Black disparity is only observable for populations not living in poverty. On the other hand, for populations living in poverty, homeownership no longer lowers psychological distress for either race. Findings suggest that financial support and mental health support are needy to address inequality in the impacts of homeownership on mental health, which could simultaneously vary by poverty status and race. Implications are discussed.

RESUMEN

OBJECTIVE: To assess the effect of geographic factors on fertility-sparing treatment or assisted reproductive technology (ART) utilization among women with gynecologic or breast cancers. METHODS: We conducted a cohort study of reproductive-aged patients (18-45 years) with early-stage cervical, endometrial, or ovarian cancer or stage I-III breast cancer diagnosed between January 2000 and December 2015 using linked data from the California Cancer Registry, the California Office of Statewide Health Planning and Development, and the Society for Assisted Reproductive Technology. Generalized linear mixed models were used to evaluate associations between distance from fertility and gynecologic oncology clinics, as well as California Healthy Places Index score (a Census-level composite community health score), and ART or fertility-sparing treatment receipt. RESULTS: We identified 7,612 women with gynecologic cancer and 35,992 women with breast cancer. Among all patients, 257 (0.6%) underwent ART. Among patients with gynecologic cancer, 1,676 (22.0%) underwent fertility-sparing treatment. Stratified by quartiles, residents who lived at increasing distances from gynecologic oncology or fertility clinics had decreased odds of undergoing fertility-sparing treatment (gynecologic oncology clinics: Q2, odds ratio [OR] 0.76, 95% CI, 0.63-0.93, P =.007; Q4, OR 0.72, 95% CI, 0.56-0.94, P =.016) (fertility clinics: Q3, OR 0.79, 95% CI, 0.65-0.97, P =.025; Q4, OR 0.67, 95% CI, 0.52-0.88, P =.004), whereas this relationship was not observed among women who resided within other quartiles (gynecologic oncology clinics: Q3, OR 0.81 95% CI, 0.65-1.01, P =.07; fertility clinics: Q2, OR 0.87 95% CI, 0.73-1.05, P =.15). Individuals who lived in communities with the highest (51 st -100 th percentile) California Healthy Places Index scores had greater odds of undergoing fertility-sparing treatment (OR 1.29, 95% CI, 1.06-1.57, P =.01; OR 1.66, 95% CI, 1.35-2.04, P =.001, respectively). The relationship between California Healthy Places Index scores and ART was even more pronounced (Q2 OR 1.9, 95% CI, 0.99-3.64, P =.05; Q3 OR 2.86, 95% CI, 1.54-5.33, P <.001; Q4 OR 3.41, 95% CI, 1.83-6.35, P <.001). CONCLUSION: Geographic disparities affect fertility-sparing treatment and ART rates among women with gynecologic or breast cancer. By acknowledging geographic factors, health care systems can ensure equitable access to fertility-preservation services.

RESUMEN

OBJECTIVE: Biologic disease-modifying antirheumatic drugs (bDMARDs) are immunosuppressants, and there have been concerns that they might impact tumor immunity in patients with cancer with rheumatoid arthritis (RA). The purpose of this study was to describe the utilization trends of bDMARD in patients with RA after breast cancer (BC) diagnosis. METHODS: We performed a retrospective cohort study of adults with RA and BC (2008 onward) from Optum's de-identified Clinformatics® Data Mart Database (CDM); the Surveillance, Epidemiology, and End Results Program (SEER) Medicare; and the Texas Cancer Registry (TCR) Medicare databases. We evaluated bDMARD utilization trends during the first three years after BC. We conducted multivariable logistic regression to evaluate the association of utilization with patient characteristics. RESULTS: A total 1,412 patients were identified in CDM and 1,439 patients in SEER/TCR-Medicare. During the three months before BC diagnosis, 28.2% (CDM) and 26.9% (SEER/TCR-Medicare) patients had received bDMARDs. Within the first three years after diagnosis, 24.1% (CDM) and 26.4% (SEER/TCR-Medicare) were receiving bDMARDs. About 70% of the patients in the two cohorts received glucocorticoids with no significant time trend increases. The largest predictor of bDMARD utilization was prior use before BC (CDM: odds ratio [OR] 27.15, 95% confidence interval [CI] 19.29-38.19; SEER/TCR: OR 18.98, 95% CI 13.72-26.26). Regional and distant BC compared to in situ or localized were also associated with lower bDMARDs utilization in SEER/TCR-Medicare (OR 0.54, 95% CI 0.36-0.82; OR 0.31, 95% CI 0.13-0.77, respectively). CONCLUSION: The utilization of tumor necrosis factor inhibitors and other bDMARDs in patients with RA and recent BC has not increased since 2008. Glucocorticoids utilization remained high. The largest predictor of bDMARD utilization was prior use before BC.

RESUMEN

CONTEXT: Provider-based human papillomavirus (HPV) vaccine promotion interventions have been widely implemented; however, the effectiveness of these approaches is unclear. OBJECTIVES: This systematic review assessed the effects and costs of provider-based interventions designed to increase HPV vaccination coverage. A meta-analysis was conducted to estimate pooled effect sizes of the interventions. DATA SOURCES: We searched PubMed, Medline, Embase, and the Cochrane Library. STUDY SELECTION: We identified articles on provider-based HPV vaccine promotion interventions published in English between 2007 and 2021. DATA EXTRACTION: Information about the interventions' effects and costs was extracted from the studies. A meta-analysis was performed to estimate the pooled intervention effects, including changes in the HPV vaccine initiation rate, HPV vaccine completion rate, and the percentage of patients receiving the next needed dose. RESULTS: We identified 32 studies of provider-based interventions to improve the HPV vaccination rate. The reported intervention strategies included provider training, provider reminders, and provider assessment and feedback. In the meta-analysis, we found significant improvements in the HPV vaccine initiation rate (3.7%) and the percentage of patients receiving the next needed dose (9.4%). LIMITATIONS: Because of the limited number of studies, we were unable to compare the same outcomes between different provider-based approaches. We found the high heterogeneity across studies. The random effects method was applied to adjust for study heterogeneity, the heterogeneity remined high for certain outcomes. CONCLUSIONS: Provider-based interventions were effective in improving HPV vaccination rates. Sustainability and continuous implementation are the central factors that contributed to intervention success.

RESUMEN

The Family Stress Model framework proposes that household income can influence child and youth development through caregiver psychological distress. While prior studies have observed stronger associations among households with lower income, the role of assets has been ignored. This is unfortunate, as many existing policies and practices that intend to improve child and family well-being are focused on assets. The purpose of this study is to clarify whether asset poverty moderates the direct and indirect effects of paths linking household income, caregiver psychological distress, and adolescent problematic behaviors. Using the 2017 and 2019 Panel Study of Income Dynamic Main Study and 2019 and 2020 Child Development Supplements, we find that the family stress processes consisting of household income, caregiver psychological distress, and adolescent problematic behaviors are less intensive for families with more assets. These findings not only add our knowledge of FSM by taking account the moderating role of assets but also advance our understanding that assets can benefit child and family well-being through alleviating family stress processes.

RESUMEN

PURPOSE: A few studies have found that children whose families are economically disadvantaged and financially struggling are at an elevated risk of victimization by their peers. However, extant research is largely descriptive. To address this gap, this study empirically tested the proposed pathways from family financial struggle to children's bullying victimization, including the role of barriers to healthcare access in this association using a nationally representative sample. DESIGN AND METHODS: The study utilizes the 2016 National Survey of Children's Health, a survey of a cross-sectional, weighted probability sample of US children (ages 0-17 years) living in 50 states and the District of Columbia, and their caregivers. The sample used for the current study included 14,374 racially and ethnically diverse caregivers of children, aged 6-11 years. RESULTS: Positive significant associations between family financial struggle and children's bullying victimization, and between financial struggle and barriers to healthcare access were found. Barriers to healthcare access mediated the association between family financial struggle and bullying victimization. PRACTICE IMPLICATIONS: Given the documented effects of bullying victimization on children, findings point to the importance of developing psychotherapeutic practices that are appropriate for children who are flagged as "high-risk."

RESUMEN

OBJECTIVE: To assess the presence of sociodemographic and clinical disparities in fertility-sparing treatment and assisted reproductive technology (ART) use among patients with a history of cervical, endometrial, or ovarian cancer. METHODS: We conducted a population-based cohort study of patients aged 18-45 years who were diagnosed with cervical cancer (stage IA, IB), endometrial cancer (grade 1, stage IA, IB), or ovarian cancer (stage IA, IC) between January 1, 2000, and December 31, 2015, using linked data from the CCR (California Cancer Registry), the California Office of Statewide Health Planning and Development, and the Society for Assisted Reproductive Technology. The primary outcome was receipt of fertility-sparing treatment , defined as surgical or medical treatment to preserve the uterus and at least one ovary. The secondary outcome was fertility preservation , defined as ART use after cancer diagnosis. Multivariable logistic regression analysis was used to estimate odds ratios and 95% CIs for the association between fertility-sparing treatment and exposures of interest: age at diagnosis, race and ethnicity, health insurance, socioeconomic status, rurality, and parity. RESULTS: We identified 7,736 patients who were diagnosed with cervical, endometrial, or ovarian cancer with eligible histology. There were 850 (18.8%) fertility-sparing procedures among 4,521 cases of cervical cancer, 108 (7.2%) among 1,504 cases of endometrial cancer, and 741 (43.3%) among 1,711 cases of ovarian cancer. Analyses demonstrated nonuniform patterns of sociodemographic disparities by cancer type for fertility-sparing treatment, and ART. Fertility-sparing treatment was more likely among young patients, overall, and of those in racial and ethnic minority groups among survivors of cervical and ovarian cancer. Use of ART was low (n=52) and was associated with a non-Hispanic White race and ethnicity designation, being of younger age (18-35 years), and having private insurance. CONCLUSION: This study demonstrates that clinical and sociodemographic disparities exist in the receipt of fertility-sparing treatment and ART use among patients with a history of cervical, endometrial, or ovarian cancer.

RESUMEN

Background: Acute care (AC) visits by cancer patients are costly sources of healthcare resources and can exert a financial burden of oncology care both for individuals with cancer and healthcare systems. We sought to identify whether cancer patients who reported more severe initial financial toxicity (FT) burdens shouldered excess risks for acute care utilization. Methods: In 225 adult patients who participated in the Economic Strain and Resilience in Cancer (ENRICh) survey study of individuals receiving ambulatory cancer care between March and September 2019, we measured the baseline FT (a multidimensional score of 0-10 indicating the least to most severe global, material, and coping FT burdens). All AC visits, including emergency department (ED) and unplanned hospital admissions, within 1-year follow-up were identified. The association between the severity of FT and the total number of AC visits was tested using Poisson regression models. Results: A total of 18.6% (n = 42) of patients had any AC visit, comprising 64.3% hospital admissions and 35.7% ED visits. Global FT burden was associated with the risk of repeat AC visits within 1-year follow-up (RR = 1.17, 95% CI 1.07-1.29, P < 0.001 for every unit increase), even after adjusting for sociodemographic and disease covariates. When examining subdimensions of FT, the burden of depleted FT coping resources (coping FT) was strongly associated with the risk of repeat AC visits (RR = 1.27, 95% CI 1.15-1.40, P < 0.001) while material FT burden showed a trend toward association (RR = 1.07, 95% CI 0.99-1.15, P = 0.07). Conclusion: In this prospective study of acute oncology care utilization outcomes among adult cancer patients, FT was a predictor of a higher burden of acute care visits. Patients with severely depleted material and also practical and social coping resources were at particular risk for repeated visits. Future studies are needed to identify whether early FT screening and intervention efforts may help to mitigate urgent acute care utilization burdens.

RESUMEN

Background: Financial toxicity (FT) reflects multi-dimensional personal economic hardships borne by cancer patients. It is unknown whether measures of FT-to date derived largely from English-speakers-adequately capture economic experiences and financial hardships of medically underserved low English proficiency US Hispanic cancer patients. We piloted a Spanish language FT instrument in this population. Methods: We piloted a Spanish version of the Economic Strain and Resilience in Cancer (ENRICh) FT measure using qualitative cognitive interviews and surveys in un-/under-insured or medically underserved, low English proficiency, Spanish-speaking Hispanics (UN-Spanish, n = 23) receiving ambulatory oncology care at a public healthcare safety net hospital in the Houston metropolitan area. Exploratory analyses compared ENRICh FT scores amongst the UN-Spanish group to: (1) un-/under-insured English-speaking Hispanics (UN-English, n = 23) from the same public facility and (2) insured English-speaking Hispanics (INS-English, n = 31) from an academic comprehensive cancer center. Multivariable logistic models compared the outcome of severe FT (score > 6). Results: UN-Spanish Hispanic participants reported high acceptability of the instrument (only 0% responded that the instrument was "very difficult to answer" and 4% that it was "very difficult to understand the questions"; 8% responded that it was "very difficult to remember resources used" and 8% that it was "very difficult to remember the burdens experienced"; and 4% responded that it was "very uncomfortable to respond"). Internal consistency of the FT measure was high (Cronbach's α = 0.906). In qualitative responses, UN-Spanish Hispanics frequently identified a total lack of credit, savings, or income and food insecurity as aspects contributing to FT. UN-Spanish and UN-English Hispanic patients were younger, had lower education and income, resided in socioeconomically deprived neighborhoods and had more advanced cancer vs. INS-English Hispanics. There was a higher likelihood of severe FT in UN-Spanish (OR = 2.73, 95% CI 0.77-9.70; p = 0.12) and UN-English (OR = 4.13, 95% CI 1.13-15.12; p = 0.03) vs. INS-English Hispanics. A higher likelihood of severely depleted FT coping resources occurred in UN-Spanish (OR = 4.00, 95% CI 1.07-14.92; p = 0.04) and UN-English (OR = 5.73, 95% CI 1.49-22.1; p = 0.01) vs. INS-English. The likelihood of FT did not differ between UN-Spanish and UN-English in both models (p = 0.59 and p = 0.62 respectively). Conclusion: In medically underserved, uninsured Hispanic patients with cancer, comprehensive Spanish-language FT assessment in low English proficiency participants was feasible, acceptable, and internally consistent. Future studies employing tailored FT assessment and intervention should encompass the key privations and hardships in this population.
