The elevated risk of ovarian clear cell carcinoma among Asian Pacific Islander women in the United States is not affected by birthplace.

OBJECTIVE: To determine incidence of ovarian clear cell cancer (OCCC) by race ethnicity and how that relationship is affected by birthplace among Asian Pacific Islanders (API). METHODS: The 18 registries of the U.S. Surveillance, Epidemiology, and End Results (SEER) dataset were queried to identify all women registered with epithelial ovarian cancer from 1973 to 2013. Relative risks of OCCC to non-OCCC based on ethnicity and birthplace were compared. RESULTS: We identified 72, 501 women with epithelial ovarian cancer in the dataset; of these, 5078 (7.0%) had OCCC and 4859 (6.7%) were API. The age-adjusted incidence rate/100,000 women of OCCC was significantly higher in API women (0.6, 0.5-0.6 95% CI) compared to any other ethnicity. A significantly higher proportion of API women had OCCC (14.5%) compared to their White (6.6%, RR 2.2, p < 0.0001) and Black counterparts (4.3%, RR 3.4, p < 0.0001). The majority of API women were foreign-born (70.8%). The relative risk of clear cell compared to non-clear cell epithelial ovarian cancer was not demonstrably different among foreign born API women with ovarian cancer (RR 1.1, 95% CI 0.9 to 1.3, p = 0.6). CONCLUSIONS: We have demonstrated that, in the US, there is an elevated risk of OCCC associated with API ethnicity. Place of birth does not appear to significantly modify the association, suggesting that the increased risk of OCCC in API women may not be affected by acculturation or environmental exposure. Future research exploring the complex relationships between ethnicity and risk of malignancy will be important as we make progress in understanding disease process and treatment.

Toward a Model of HPV Vaccine Series Completion in Adolescent Hispanic Males: Identifying Mothers' Salient Behavioral, Normative, and Control Beliefs.

Human papillomavirus (HPV) vaccine series completion among adolescent Hispanic males (35%) is lower than the Healthy People 2020 80% goal. This directed qualitative content analysis identified mothers' beliefs about their sons completing the series. We found that mothers (N = 19) (1) express positive feelings; (2) believe the vaccine has positive effects; (3) identify the father and doctors as supporters and friends as nonsupporters; (4) list health insurance, transportation, and clinic reminders as facilitators; and (5) mention affordability as a barrier to vaccine completion. Results provide guidance for interventions. Increasing HPV vaccination among boys will decrease the overall incidence of HPV in this population.

Identifying Hispanic mothers' salient beliefs about human papillomavirus vaccine initiation in their adolescent daughters.

Guided by the Integrative Model of Behavioral Prediction, we identify mothers' salient beliefs regarding their daughters' initiation of the human papillomavirus vaccine series. In all, 34 Hispanic mothers responded to elicitation questions. Salient beliefs included the following: (1) feeling secure, happy, relieved, concerned, and fear about vaccinating; (2) believing that vaccinating prevents and protects from human papillomavirus but may result in side effects and sexual disinhibition; (3) identifying the daughter, father, mother, aunt, friends, and grandmothers as supporters/non-supporters; and (4) affordability, transportation, clinic distance, and making appointments as facilitators/barriers. This study begins the process of building a model of human papillomavirus vaccine initiation for this population.

Hispanic Mothers' Beliefs About Having Their Adolescent Sons Initiate the HPV Vaccine Series.

Rates of HPV vaccination among adolescent Hispanic males lag far behind the Healthy People 2020 80% goal. This study identified Hispanic mothers' salient beliefs regarding having their sons initiate the HPV vaccine series. Twenty-seven Hispanic mothers completed in-depth interviews. They responded to questions that elicited the salient behavioral, normative and control beliefs associated with initiating the HPV vaccine series. We content analyzed their responses. We found that, regarding having their sons initiate the HPV vaccine, mothers: (1) express mostly positive feelings; (2) believe that the vaccine has positive effects, with side effects as the main negative effect; (3) believe that their sons' father and doctor support vaccination while some friends do not; and (4) believe that vaccine affordability, transportation and the support of their sons' father facilitate vaccine initiation. Overall, mothers held positive salient beliefs about the HPV vaccine including that it protects their son's health, has minimal side effects and is recommended by physicians. We are more likely to increase vaccination rates among adolescent Hispanic males if we address mothers' salient beliefs, including reinforcing their positive beliefs.

Survival of women with microinvasive adenocarcinoma of the cervix is not improved by radical surgery.

BACKGROUND: Treatment for early-invasive adenocarcinoma of the cervix remains controversial. Although data have shown similar survival rates to those seen with squamous cell carcinoma, conservative options for patients with microinvasive adenocarcinoma have not been as widely accepted. Despite comparable survival outcomes, patients with early-invasive adenocarcinoma are still routinely subjected to more radical surgical techniques than their equivalently staged squamous cell counterparts. OBJECTIVE: The objective of the study was to evaluate how less radical surgery has an impact on 5 year survival in patients with microinvasive adenocarcinoma of the cervix. STUDY DESIGN: The Surveillance, Epidemiology, and End Results database was queried from 1988 through 2010 to perform a retrospective analysis of women with International Federation of Gynecology and Obstetrics stage IA1 or IA2 cervical carcinoma. Five year survival by procedure type (local excision, simple hysterectomy, or radical hysterectomy) was determined for each cell type (squamous or adenocarcinoma), as was lymph node status. RESULTS: Among 1567 patients with cervical adenocarcinoma, 5 year survival was 97.3% (confidence interval, 95.8-98.2%) for stage IA1 disease and 98.3% (confidence interval, 96.5%, 99.2%) for stage IA2. For comparison, the 5-year survival rates for 5,749 patients with stage IAI or lA2 squamous cell carcinoma were 96.7% (confidence interval, 96.0-97.3%) and 95.6% (confidence interval, 94.4-96.5%), respectively. For stage IA1 ACA, survival was 96.6%, 98.4% and 96.5% following excision, hysterectomy and radical hysterectomy, respectively. For stage IA2 ACA, survival rates were 100%, 96.9% and 99.4%, respectively. There was no statistical difference in survival between patients having either cell type undergoing local excision (P = .26), simple hysterectomy (P = .08), or radical hysterectomy (P = .87). We also found no statistically significant difference in survival among patients with adenocarcinoma compared by treatment type (local excision compared with simple hysterectomy [P = .64]; local excision compared with radical hysterectomy [P = .82]; or simple hysterectomy compared with radical hysterectomy [P = .70]). Among patients with adenocarcinoma, 0.97% had positive pelvic lymph nodes, none had positive aortic lymph nodes, and 91.85% had confirmed negative lymph nodes. For squamous cell carcinoma, 0.72% of patients had positive pelvic lymph nodes and 0.10% had positive aortic lymph nodes. CONCLUSION: There was no significant difference in survival when patients were compared by cell type or procedure, suggesting that survival of patients with microinvasive adenocarcinoma is not improved by utilizing more invasive surgical methods. Regardless of histology, the frequency of nodal involvement was very low among both groups, supporting an overall excellent prognosis for all patients with microinvasive disease. We submit these data as evidence that preoperative planning of more conservative techniques is appropriate, not just for those with squamous histology or who desire future fertility, but for all patients with microinvasive cervical disease.

Using Social Marketing Theory as a Framework for Understanding and Increasing HPV Vaccine Series Completion Among Hispanic Adolescents: A Qualitative Study.

HPV vaccine series completion rates among adolescent Hispanic females and males (~39 and 21 %, respectively) are far below the Healthy People 80 % coverage goal. Completion of the 3-dose vaccine series is critical to reducing the incidence of HPV-associated cancers. This formative study applies social marketing theory to assess the needs and preferences of Hispanic mothers in order to guide the development of interventions to increase HPV vaccine completion. We conducted 51 in-depth interviews with Hispanic mothers of adolescents to identify the key concepts of social marketing theory (i.e., the four P's: product, price, place and promotion). Results suggest that a desire complete the vaccine series, vaccine reminders and preventing illnesses and protecting their children against illnesses and HPV all influence vaccination (product). The majority of Completed mothers did not experience barriers that prevented vaccine series completion and Initiated mothers perceived a lack of health insurance and the cost of the vaccine as potential barriers. Informational barriers were prevalent across both market segments (price). Clinics are important locations for deciding to complete the vaccine series (place). They are the preferred sources to obtain information about the HPV vaccine thus making them ideal locations to deliver intervention messages, followed by television, the child's school and brochures (promotion). Increasing HPV vaccine coverage among Hispanic adolescents will reduce the rates of HPV-associated cancers and the cervical cancer health disparity among Hispanic women. This research can inform the development of an intervention to increase HPV vaccine series completion in this population.

Bariatric Surgery and Liver Cancer in a Consortium of Academic Medical Centers.

Obesity is implicated as an important factor in the rising incidence of liver cancer in the USA. Bariatric surgery is increasingly used for treating morbid obesity and comorbidities. Using administrative data from UHC, a consortium of academic medical centers in the USA, we compared the prevalence of liver cancer among admissions with and without a history of bariatric surgery within a 3-year period. Admissions with a history of bariatric surgery had a 61 % lower prevalence of liver cancer compared to those without a history of bariatric surgery (prevalence ratio 0.39, 95 % confidence interval 0.35-0.44), and these inverse associations persisted within strata of sex, race, and ethnicity. This hospital administrative record-based analysis suggests that bariatric surgery could play a role in liver cancer prevention.

Urinary diversions: A time to enrich surgical training?

OBJECTIVE: To assess the potential exposure to complex urologic procedures, specifically urinary diversion, during a gynecologic oncology fellowship. METHODS: We queried the University HealthSystem Consortium (UHC) database to determine the total number of urinary diversions performed from October 2008 to August 2012. This data was used to estimate the mean number of urinary diversions performed each year. Gender, primary diagnosis, type of diversion, gynecologic oncologist involvement, and medical center were explored. RESULTS: Of the nearly 21,000 urinary diversions performed in UHC participating hospitals during the study period, 6180 (29.5%) were performed in women. On average, 1648 urinary diversions are performed in women each year, with gynecologic malignancies accounting for 6.8% of cases. We estimate that a gynecologic oncologist was involved with 87 cases per year at nonprofit academic medical centers in the US. With approximately 112 clinically active fellows per year during the study period, this equates to less than one diversion per clinical fellow per year if cases are equally distributed among centers. However, the majority of urinary diversions with gynecologic oncologist involvement were performed at just a fraction of centers. Thus, only a small contingent of fellows may be getting the greatest exposure to urinary diversions. CONCLUSIONS: The majority of urinary diversions in women in the US are performed for bladder carcinoma by urologists. The estimated number of cases per clinical gynecologic oncology fellow per year is less than one. Strategies to improve fellow exposure to urinary diversion and consideration of alternative surgical training modalities should be explored.

Continuous Subcutaneous Insulin Infusion versus Multiple Daily Injections of Insulin for the Management of Type 1 Diabetes Mellitus in Pregnancy: Association with Neonatal Chemical Hypoglycemia.

OBJECTIVE: We hypothesized that patients with type 1 diabetes mellitus (T1DM) who were managed during their pregnancy with a continuous subcutaneous insulin infusion (CSII) would have a lower incidence of neonatal hypoglycemia (NH) than patients managed with multiple daily injections (MDI) of insulin. STUDY DESIGN: This was a retrospective cohort of 95 women with T1DM who delivered singleton, term neonates between 2007 and 2014. The primary outcome was incidence of NH (capillary plasma glucose ≤ 45 mg/dL) in the first 24 hours after birth. RESULTS: The incidence of NH was 66.0% (62/95). The NH rate was significantly higher in women managed with CSII versus MDI (62 vs. 38%, p = 0.024). Neonates with NH had a higher birth weight (3,867 ± 658 vs. 3,414 ± 619 g, p = 0.002). When analyzing intrapartum glucose management, mothers of neonates with NH had significantly less time managed on an insulin infusion (median interquartile range 7 [3.5-30.5] vs. 17.5 [2.0-17.5] hours, p = 0.014). In multivariable analysis, only maternal body mass index (BMI) (p = 0.035) and time on an insulin infusion (p = 0.043) were significantly associated with NH. CONCLUSION: In our population of patients with T1DM, CSII was more prevalent in the NH group; however, when controlling for other factors, intrapartum glucose management and early maternal BMI were the only variables associated with NH.

Ketorolac for Pain Control With Intrauterine Device Placement: A Randomized Controlled Trial.

OBJECTIVE: To evaluate intramuscular ketorolac compared with placebo saline injection for pain control with intrauterine device (IUD) placement. METHODS: We conducted a randomized, double-blind, placebo-controlled trial between July 2012 and March 2014. Patients received 30 mg ketorolac or placebo saline intramuscular injection 30 minutes before IUD placement. The primary outcome was pain with IUD placement on a 10-cm visual analog scale. Sample size was calculated to provide 80% power to show a 2.0-cm difference (α=0.05) in the primary outcome. Secondary outcomes included pain with study drug injection, speculum insertion, tenaculum placement, uterine sounding, and at 5 and 15 minutes after IUD placement. RESULTS: A total of 67 women participated in the study, 33 in the ketorolac arm and 34 in the placebo arm. There were no differences in baseline demographics including age, body mass index, and race. There were no differences in median pain scores for IUD placement in the placebo compared with ketorolac groups (5.2 compared with 3.6 cm, P=.99). There was a decrease in median pain scores at 5 minutes (2.2 compared with 0.3 cm, P≤.001) and 15 minutes (1.6 compared with 0.1 cm, P≤.001) after IUD placement but no difference for all other time points. Nulliparous participants (n=16, eight per arm) had a decrease in pain scores with IUD placement (8.1 compared with 5.4 cm, P=.02). In this study, 22% of participants in the placebo group and 18% in the ketorolac group reported injection pain was as painful as IUD placement. CONCLUSION: Ketorolac does not reduce pain with IUD placement but does reduce pain at 5 and 15 minutes after placement. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov; www.clinicaltrials.gov, NCT01664559. LEVEL OF EVIDENCE: I.

Increased prevalence of comorbid conditions in women with uterine cancer.

OBJECTIVES: To compare comorbidities of women with uterine cancer (UC) to controls so as to aid in development of survivorship care plans and programs. METHODS: Retrospective cohort study using the University HealthSystem Consortium (UHC) database that compared women who had a hysterectomy for UC to women without UC undergoing hysterectomy. Frequencies and odds ratios (ORs) of 26 comorbidities were calculated. Mantel-Haenszel stratified ORs were determined to correct for different age distributions between the UC and control groups using UHC predetermined age groups. RESULTS: 23,227 patients in the dataset were included in the UC cohort, and 142,601 patients served as controls. Uncorrected ORs≥2 were found for hypertension, diabetes, obesity, congestive heart failure, pulmonary circulatory diseases, peripheral vascular disease, and renal failure. Higher ORs for UC remained significant after stratification by age for hypertension (OR=1.7), diabetes (OR=2.1), obesity (OR=3.3), congestive heart failure (OR=1.5), pulmonary circulatory disorders (OR=1.7), and renal failure (OR=1.2). CONCLUSIONS: Multiple comorbid conditions, specifically those related to the metabolic syndrome, were more prevalent in UC survivors than in the general population, and this difference persisted after adjustment for age. UC survivorship programs should plan to allocate resources to account for these differences in healthcare needs.

Using the Theory of Planned Behavior to Understand Cervical Cancer Screening Among Latinas.

To reduce the high incidence of cervical cancer among Latinas in the United States it is important to understand factors that predict screening behavior. The aim of this study was to test the utility of theory of planned behavior in predicting cervical cancer screening among a group of Latinas. A sample of Latinas (N = 614) completed a baseline survey about Pap test attitudes subjective norms, perceived behavioral control, and intention to be screened for cervical cancer. At 6 months postbaseline, cervical cancer screening behavior was assessed. Structural equation modeling was used to test the theory. Model fit statistics indicated good model fit: χ(2)(48) = 54.32, p = .246; comparative fit index = .992; root mean square error of approximation = .015; weighted root mean square residual = .687. Subjective norms (p = .005) and perceived behavioral control (p < .0001) were positively associated with intention to be screened for cervical cancer, and the intention to be screened predicted actual cervical cancer screening (p < .0001). The proportion of variance (R2) in intention accounted for by the predictors was .276 and the R2 in cervical cancer screening accounted for was .130. This study provides support for the use of the theory of planned behavior in predicting cervical cancer screening among Latinas. This knowledge can be used to inform the development of a theory of planned behavior-based intervention to increase cervical cancer screening among Latinas and reduce the high incidence of cervical cancer in this group of women.

FAK Inhibition disrupts a ß5 integrin signaling axis controlling anchorage-independent ovarian carcinoma growth.

Ovarian cancer ascites fluid contains matrix proteins that can impact tumor growth via integrin receptor binding. In human ovarian tumor tissue arrays, we find that activation of the cytoplasmic focal adhesion (FAK) tyrosine kinase parallels increased tumor stage, ß5 integrin, and osteopontin matrix staining. Elevated osteopontin, ß5 integrin, and FAK mRNA levels are associated with decreased serous ovarian cancer patient survival. FAK remains active within ovarian cancer cells grown as spheroids, and anchorage-independent growth analyses of seven ovarian carcinoma cell lines identified sensitive (HEY, OVCAR8) and resistant (SKOV3-IP, OVCAR10) cells to 0.1 µmol/L FAK inhibitor (VS-4718, formerly PND-1186) treatment. VS-4718 promoted HEY and OVCAR8 G0-G1 cell-cycle arrest followed by cell death, whereas growth of SKOV3-IP and OVCAR10 cells was resistant to 1.0 µmol/L VS-4718. In HEY cells, genetic or pharmacological FAK inhibition prevented tumor growth in mice with corresponding reductions in ß5 integrin and osteopontin expression. ß5 knockdown reduced HEY cell growth in soft agar, tumor growth in mice, and both FAK Y397 phosphorylation and osteopontin expression in spheroids. FAK inhibitor-resistant (SKOV3-IP, OVCAR10) cells exhibited anchorage-independent Akt S473 phosphorylation, and expression of membrane-targeted and active Akt in sensitive cells (HEY, OVCAR8) increased growth but did not create a FAK inhibitor-resistant phenotype. These results link osteopontin, ß5 integrin, and FAK in promoting ovarian tumor progression. ß5 integrin expression may serve as a biomarker for serous ovarian carcinoma cells that possess active FAK signaling.

An ecological analysis of the incidence of invasive squamous cell carcinoma of the cervix in Hispanic women in the United States.

PURPOSE: To evaluate the relationship between county-level characteristics and the incidence of invasive squamous cell carcinoma of the cervix among Hispanic women. METHODS: The Surveillance, Epidemiology and End Results (SEER) Program's 18 registries from 2000-2009 were queried. Average annual age-adjusted incidence rates for invasive squamous cell carcinoma of the cervix among Hispanic women were calculated. Patients were then stratified by residence in a county with high vs low percent language isolation (LI), income, and education levels. RESULTS: Among Hispanic women living in high LI, the highest incidence of cervical cancer was found among women residing in counties with low incomes and low education levels (11.3; CI: 10.8-11.8). CONCLUSIONS: County-level characteristics are associated with cervical cancer incidence in Hispanic women. A more precise understanding of contributing socioeconomic factors such as language may facilitate the design of targeted research studies and interventions, and community-level public policy interventions might be effective in reducing the unequal burden of cervical cancer in Hispanic women in the United States.

Analyses of merlin/NF2 connection to FAK inhibitor responsiveness in serous ovarian cancer.

OBJECTIVE: Focal adhesion kinase (FAK) is overexpressed in serous ovarian cancer. Loss of merlin, a product of the neurofibromatosis 2 tumor suppressor gene, is being evaluated as a biomarker for FAK inhibitor sensitivity in mesothelioma. Connections between merlin and FAK in ovarian cancer remain undefined. METHODS: Nine human and two murine ovarian cancer cell lines were analyzed for growth in the presence of a small molecule FAK inhibitor (PF-271, also termed VS-6062) from 0.1 to 1 µM for 72 h. Merlin was evaluated by immunoblotting and immunostaining of a human ovarian tumor tissue array. Growth of cells was analyzed in an orthotopic tumor model and evaluated in vitro after stable shRNA-mediated merlin knockdown. RESULTS: Greater than 50% inhibition of OVCAR8, HEY, and ID8-IP ovarian carcinoma cell growth occurred with 0.1 µM PF-271 in anchorage-independent (p<0.001) but not in adherent culture conditions. PF-271-mediated reduction in FAK Y397 phosphorylation occurred independently of growth inhibition. Suspended growth of OVCAR3, OVCAR10, IGROV1, IGROV1-IP, SKOV3, SKOV3-IP, A2780, and 5009-MOVCAR was not affected by 0.1 µM PF-271. Merlin expression did not correlate with serous ovarian tumor grade or stage. PF-271 (30 mg/kg, BID) did not inhibit 5009-MOVCAR tumor growth and merlin knockdown in SKOV3-IP and OVCAR10 cells did not alter suspended cell growth upon PF-271 addition. CONCLUSIONS: Differential responsiveness to FAK inhibitor treatment was observed. Intrinsic low merlin protein level correlated with PF-271-mediated anchorage-independent growth inhibition, but reduction in merlin expression did not induce sensitivity to FAK inhibition. Merlin levels may be useful for patient stratification in FAK inhibitor trials.

Bariatric surgery decreases the risk of uterine malignancy.

OBJECTIVE: To describe the risk of uterine malignancy among women who have had weight loss surgery. METHODS: We performed a retrospective cohort study among inpatient admissions of women 18years, or older, registered in the University HealthSystem Consortium (UHC) dataset. The rate of uterine malignancy per hospital admission was calculated. Rates were compared according to whether diagnoses at the time of discharge included history of bariatric surgery, and further, according to whether there was a diagnosis of obesity. RESULTS: In admissions of patients who did not have a history of prior bariatric surgery, the rate of uterine malignancy was 599/100,000 (95% CI 590 to 610). Among obese women who had not previously undergone bariatric operations, the rate was 1409/100,000 (95% CI 1380 to 1440). Of women admitted who had a history of bariatric surgery, the rate of uterine malignancy was 408/100,000 (95% CI 370 to 450). The relative risk of uterine malignancy in all admissions for women who had prior bariatric surgery, compared to obese women who had not had bariatric surgery, was 0.29 (95% CI 0.26-0.32). Among women who had bariatric surgery and were not currently obese, the relative risk of uterine malignancy was 0.19 (95% CI 0.17-0.22) compared to obese women who had not undergone bariatric surgery. CONCLUSION: A history of bariatric surgery is associated with a 71% reduced risk for uterine malignancy overall, and an 81% reduced risk if normal weight is maintained after surgery. This finding suggests that obesity may be a modifiable risk factor related to development of endometrial cancer.

Inhibition of endothelial FAK activity prevents tumor metastasis by enhancing barrier function.

Pharmacological focal adhesion kinase (FAK) inhibition prevents tumor growth and metastasis, via actions on both tumor and stromal cells. In this paper, we show that vascular endothelial cadherin (VEC) tyrosine (Y) 658 is a target of FAK in tumor-associated endothelial cells (ECs). Conditional kinase-dead FAK knockin within ECs inhibited recombinant vascular endothelial growth factor (VEGF-A) and tumor-induced VEC-Y658 phosphorylation in vivo. Adherence of VEGF-expressing tumor cells to ECs triggered FAK-dependent VEC-Y658 phosphorylation. Both FAK inhibition and VEC-Y658F mutation within ECs prevented VEGF-initiated paracellular permeability and tumor cell transmigration across EC barriers. In mice, EC FAK inhibition prevented VEGF-dependent tumor cell extravasation and melanoma dermal to lung metastasis without affecting primary tumor growth. As pharmacological c-Src or FAK inhibition prevents VEGF-stimulated c-Src and FAK translocation to EC adherens junctions, but FAK inhibition does not alter c-Src activation, our experiments identify EC FAK as a key intermediate between c-Src and the regulation of EC barrier function controlling tumor metastasis.

The influence of time perspective on cervical cancer screening among Latinas in the United States.

To develop effective interventions to increase cervical cancer screening among Latinas, we should understand the role of cultural factors, such as time perspective, in the decision to be screened. We examined the relation between present time orientation, future time orientation, and self-reported cervical cancer screening among Latinas. A group of 206 Latinas completed a survey measuring factors associated with screening. Logistic regression analyses revealed that future time orientation was significantly associated with self-reported screening. Understanding the influence of time orientation on cervical cancer screening will assist us in developing interventions that effectively target time perspective and screening.

Regional variation in surgical assessment of lymph nodes for staging among women with early-stage epithelial ovarian cancer.

OBJECTIVE: To investigate geographical and socioeconomic variations in performance of lymph node dissection for the evaluation of patients with early-stage epithelial ovarian cancer. METHODS: A population-based, retrospective cohort study was conducted using data from the National Cancer Institute's SEER Program for 15 geographic registries and county-level measures. Women with early-stage epithelial ovarian cancer registered between 2000 and 2008 with known lymph node assessment status were studied. A multiple logistic regression analysis was used to evaluate the differences in the likelihood of lymph node assessment according to geographic SEER region. RESULTS: After adjusting for tumor characteristics, demographics, and area-based socioeconomic measures, a significant relationship between SEER region and lymph node dissection remained. Compared to the region with the highest proportion of lymph node dissection, there is a significantly lower probability of surgical assessment of lymph nodes in 8 of the remaining 14 geographical regions. CONCLUSIONS: The variation in ovarian cancer surgical care by region reported in this study has implications for access and outcomes for patients with early-stage disease. Study findings merit further investigation and should be characterized to permit targeted interventions aimed at reducing the observed disparities.

Understanding cervical cancer screening intentions among Latinas using an expanded theory of planned behavior model.

We examined the utility of an expanded theory of planned behavior (TPB) model in predicting cervical cancer screening intentions among Latinas. The model included acculturation and past cervical cancer screening behavior along with attitude, subjective norms, and perceived behavioral control. This cross-sectional study included a sample of 206 Latinas who responded to a self-administered survey. Structural equation modeling was employed to test the expanded TPB model. Acculturation (p = .025) and past screening behavior (p = .001) along with attitude (p = .019), subjective norms (p = .028), and perceived behavioral control (p = .014) predicted the intention to be screened for cervical cancer. Our findings suggest that the TPB is a useful model for understanding cervical cancer screening intentions among Latinas when both past behavior and culture are included. This research highlights the importance of culture on behavior and indicates a need to develop culturally sensitive, theory-based interventions to encourage screening and reduce cervical cancer-related health disparities in Latinas.
