RESUMO

OBJECTIVE: To review the management of ovarian cancer (OCa) associated hydronephrosis (HN). Specifically, we aim to identify optimal management of HN in the acute setting, predictors of HN resolution, and the role of surgery (tumor debulking/(+/-)ureterolysis/hysterectomy). MATERIALS/METHODS: The study cohort included OCa patients managed at our institution from 2004-2019 that developed OCa-associated HN. Initial HN management was recorded as none, retrograde ureteral stent (RUS) or percutaneous nephrostomy tube (PCN). Primary outcomes included (1) HN management failure, (2) HN management complications, and (3) HN resolution. Patient, cancer, and treatment predictors of outcomes were assessed using logistic regression and fine-Gray competing risk models. RESULTS: Of 2580 OCa patients, 190 (7.4%) developed HN. HN was treated in 121; 90 (74.4%) with RUS, 31 (25.6%) with PCN. Complication rates were similar between PCN and RUS (83% vs 85.1%; P = .79; all Clavian Grade I/II). Initial HN treatment failure occurred in 28 patients, predicted by renal atrophy (hazard ratios (HR) 3.27, P <.01). HN resolution occurred in only 52 (27%) patients and was predicted by lower International Federation of Gynecology and Obstetrics (FIGO) stage (FIGO III/IV HR 0.42, P <.01) and surgical tumor debulking/ureterolysis (HR 2.83, P = .02). CONCLUSION: Resolution of HN associated with malignant obstruction from OCa is rare and is most closely associated with tumor debulking and International Federation of Gynecology and Obstetrics (FIGO) stage. Initial endoscopic treatment modality was not significantly associated with complications or resolution, though RUS failures were slightly more common. Ureteral reconstruction at time of debulking/ureterolysis is potentially underutilized.

RESUMO

BACKGROUND: Standard first-line chemotherapy for endometrial cancer is paclitaxel plus carboplatin. The benefit of adding pembrolizumab to chemotherapy remains unclear. METHODS: In this double-blind, placebo-controlled, randomized, phase 3 trial, we assigned 816 patients with measurable disease (stage III or IVA) or stage IVB or recurrent endometrial cancer in a 1:1 ratio to receive pembrolizumab or placebo along with combination therapy with paclitaxel plus carboplatin. The administration of pembrolizumab or placebo was planned in 6 cycles every 3 weeks, followed by up to 14 maintenance cycles every 6 weeks. The patients were stratified into two cohorts according to whether they had mismatch repair-deficient (dMMR) or mismatch repair-proficient (pMMR) disease. Previous adjuvant chemotherapy was permitted if the treatment-free interval was at least 12 months. The primary outcome was progression-free survival in the two cohorts. Interim analyses were scheduled to be triggered after the occurrence of at least 84 events of death or progression in the dMMR cohort and at least 196 events in the pMMR cohort. RESULTS: In the 12-month analysis, Kaplan-Meier estimates of progression-free survival in the dMMR cohort were 74% in the pembrolizumab group and 38% in the placebo group (hazard ratio for progression or death, 0.30; 95% confidence interval [CI], 0.19 to 0.48; P<0.001), a 70% difference in relative risk. In the pMMR cohort, median progression-free survival was 13.1 months with pembrolizumab and 8.7 months with placebo (hazard ratio, 0.54; 95% CI, 0.41 to 0.71; P<0.001). Adverse events were as expected for pembrolizumab and combination chemotherapy. CONCLUSIONS: In patients with advanced or recurrent endometrial cancer, the addition of pembrolizumab to standard chemotherapy resulted in significantly longer progression-free survival than with chemotherapy alone.

RESUMO

INTRODUCTION: To understand the experiences of emergency nurses who have returned to work after parental leave, specifically relating to the return to work transition, work-life balance, work engagement, and opportunities to continue human milk expression. METHODS: Nurses (N = 19) were recruited from 5 emergency departments within 1 hospital system in the United States Midwest. Nurses (n = 11) were eligible to participate in a one-on-one interview if they had returned from parental leave within 6 months of the interview date. Nurses (n = 8) were eligible to participate in a focus group if they had returned from parental leave within 2 years of the interview date. Interviews were structured and data collection concluded when researchers believed data saturation was reached. Interviews were audio recorded and transcribed verbatim. Data were analyzed using Braun and Clarke's qualitative thematic analysis 6-phase framework. RESULTS: Three major themes from the data were identified: (1) work engagement, (2) lactation, and (3) childcare. Work engagement was broken down into the subthemes: lack of communication, perceived engagement expectations, and actual engagement. Lactation was broken down into the subthemes: the act of pumping, lactation breaks, and lactation rooms. The coronavirus disease 2019 pandemic impact on return-to-work is described under each major theme. DISCUSSION: Our findings provide insight into the unique challenges and experiences of nurses navigating parental leave and return-to-work in the emergency department. Strategies such as provision of managerial check-ins, return to work reorientation, lactation break coverage, enhanced supplementary lactation support, and leadership-provided accommodation may lighten the burden of these challenges and improve the returning nurse's job satisfaction.

RESUMO

Purpose: The objective of this study was to assess the efficacy and safety of pembrolizumab in combination with standard carboplatin/paclitaxel in patients with advanced endometrial cancer (EC). Patients and Methods: This single-arm, open-label, multi-center phase II study enrolled patients with RECIST measurable advanced EC. Patients could have received < 1 prior platinum-based regimen and < one non-platinum chemotherapy. The primary endpoint was objective response rate (ORR). Planned sample size of 46 subjects provided 80% power to detect 15% ORR improvement compared to historical control rate of 50%. Results: 46 patients were enrolled, and 43 were evaluable for ORR. Median age was 66 (range: 43-86). Thirty-four (73.9%) patients had recurrent and 12 (26.1%) primary metastatic EC. Patients received carboplatin AUC 6, paclitaxel 175mg/m2 and pembrolizumab 200mg IV every 3 weeks for up to 6 cycles. ORR was 74.4% (32/43), higher than historic controls (p = 0.001). Median PFS was 10.6 months (95% CI 8.3-13.9 months). The most common grade 1-2 treatment related adverse event (TRAEs) included anemia (56.5%), alopecia (47.8%), fatigue (47.8%) and neuropathy (13%), while the most common grade 3-4 TRAEs were lymphopenia, leukopenia, and anemia (19.6% each). High-dimensional spectral flow cytometry (CyTEK) identified enrichment in peripheral CD8+ and CD4+ T cell populations at baseline in responders. The CD8+ T cell compartment in responders exhibited greater expression levels of PD-1 and PD-L1 and higher abundance of effector memory CD8+ cells compared to non-responders. Conclusions: Addition of pembrolizumab to carboplatin and paclitaxel for advanced EC was tolerated and improved ORR compared to historical outcomes.

RESUMO

OBJECTIVE: The objective of this study was to compare the rate of groin recurrence among women undergoing superficial or deep inguinal lymph node dissections in suspected early-stage vulvar carcinoma. Secondary objectives included comparison of overall survival and post-operative morbidity between the study groups. METHODS: A retrospective cohort of 233 patients with squamous cell carcinoma (SCC) of the vulva who underwent an inguinal lymph node dissection at two major academic institutions from 1999 to 2017 were analyzed. Demographic, surgical, recurrence, survival, and post-operative morbidity data were collected for 233 patients, resulting in a total of 400 groin node dissections analyzed. RESULTS: Rates of overall primary recurrence of disease between superficial and deep inguinal LND (42.5 vs. 39.8%, p = 0.70) and rates of inguinal recurrence (3.4 vs. 8.3%, p = 0.16) were similar. Overall rates of postoperative morbidity were significantly higher in the cohort undergoing deep LND (70.3% vs 44.3%, p < 0.01). Rates of lymphedema (42.4 vs 15.9%, p < 0.01), readmission (26.3 vs 6.8%, p < 0.01), and infection (40.7 vs 14.8%, p < 0.01) were all significantly higher among patients undergoing deep LND. There was no significant difference noted in overall survival between the study groups when adjusting for stage and age (HR 1.08, p = 0.84). CONCLUSION: Superficial inguinal LND had no significant difference in rate of recurrence or overall survival when compared to deep inguinal LND in patients with vulvar SCC. Those who received a deep LND had a significant increase in overall morbidity, including lymphedema, readmission, and infection. For patients who cannot undergo or fail sentinel lymph node mapping, a superficial inguinal lymph node dissection may have similar outcomes in recurrence and overall survival with a reduction in overall morbidity as compared to a complete, or deep, lymph node dissection.

RESUMO

OBJECTIVE: To identify predictors of hydronephrosis (HN) resolution and HN treatment failure. HN is a common comorbid condition with cervical cancer (CCa). Treatments for CCa continue to improve and long-term management strategies of HN are becoming increasingly necessary. METHODS: A query of a single hospital (2004 - 2019) ICD-9 and CPT codes was made to develop a cohort of CCa patients with HN. A retrospective review was performed. The effects of patient, renal/HN, and cancer covariates on time to HN treatment failure, treatment complications and time to HN resolution were evaluated using logistic regression and competing risk Cox regression models. RESULTS: Of the 1670 women treated for CCa during the study period, 179 (10.7%) developed HN (n = 72 (40%) bilateral), 78 (44%) at time of CCa diagnosis and 101 (56%) as a result of treatment, of which 145 (81%) underwent initial treatment with a PCN (n = 77, 53%) or US (n = 68, 47%). Complication rates were similar between PCN (56%) and US (61%) when adjusting for treatment time. Initial treatment failure was more likely with US vs PCN (HR 3.2, P <0.01). HN resolution (n = 32, 22%) without reconstruction was predicted by HN concurrent with CCa diagnosis (HR 3.1, P <0.01) and bilateral HN (HR 0.2, P <0.01). CONCLUSION: CCa associated HN has a resolution rate of only 19% at 12 months. Those presenting with HN after CCa treatment are less likely to resolve without reconstruction. PCN and US have similar complication rates but initial US placement has a nearly three times increased risk of failing than PCN.

RESUMO

PURPOSE: This surgical window of opportunity (window) study assessed the short-term effect of medroxyprogesterone acetate (MPA) alone versus MPA plus the histone deacetylase (HDAC) inhibitor entinostat on regulation of progesterone receptor (PR) in women with newly diagnosed endometrioid endometrial adenocarcinoma. PATIENTS AND METHODS: This multisite, randomized, open-label surgical window study treated women intramuscularly on day 1 with 400 mg MPA. Entinostat given 5 mg by mouth on days 1, 8, and 15 was randomly assigned with equal probability. Surgery followed on days 21-24. Pretreatment and posttreatment tissue was assessed for PR H-scores, Ki-67 levels, and histologic response. RESULTS: Fifty patients were accrued in 4 months; 22 and 20 participants had PR evaluable pretreatment and posttreatment slides in the MPA and MPA/entinostat arms, respectively. Median posttreatment PR H-scores were significantly lower than pretreatment H-scores in both arms but did not differ significantly (MPA: 247 vs. 27, MPA/entinostat 260 vs. 23, respectively, P = 0.87). Decreased Ki-67 was shown in 90% treated with MPA/entinostat compared with 68% treated with MPA alone (P = 0.13). Median PR H-score decreases were larger when Ki-67 was decreased (208) versus not decreased (45). The decrease in PR pretreatment versus posttreatment was associated with loss of Ki-67 nuclear staining, consistent with reduced cellular proliferation (P < 0.008). CONCLUSIONS: This surgical window trial rapidly accrued in a multisite setting and evaluated PR as its primary endpoint and Ki-67 as secondary endpoint. Despite no immediate effect of entinostat on PR in this short-term study, lessons learned can inform future window and treatment trials.

RESUMO

OBJECTIVES: The primary objective was to evaluate the impact of a multimodal perioperative pain regimen on length of hospital stay for patients undergoing laparotomy with a gynecologic oncologist. METHODS: We compared 52 patients who underwent laparotomy with a gynecologic oncologist at a single institution between 2017 and 2018, after implementation of a multimodal perioperative pain regimen, to a historic cohort of 94 patients (2016-2017). The multimodal pain regimen included pre- and post-operative administration of oral acetaminophen, gabapentin, and celecoxib, in addition to standard narcotics and optional epidural analgesia. Demographic, surgical, and post-operative data were collected. RESULTS: On multivariable analysis, bowel resection, stage, surgery length, age, and cohort group were retained as significant independent predictors of length of stay. Patients undergoing laparotomy prior to the pain protocol had a length of stay 1.26 times longer than patients during the post-implementation period (p < 0.01). For complex surgical patients, this translated into a reduction in length of hospital stay of 1.73 days. There was a significant reduction in pain scale score on post-operative day zero from 5 to 3 (p = 0.02) and a non-significant overall reduction of post-operative morphine equivalents, with similar adverse outcomes. CONCLUSION: Implementation of a multimodal perioperative pain regimen in patients undergoing gynecologic oncology laparotomy was associated with a significant reduction of length of hospital stay and improved patient-perceived pain, even in the absence of a complete Enhanced Recovery After Surgery (ERAS) protocol.

RESUMO

OBJECTIVES: The objective of this study was to determine if there has been an increase in the age of diagnosis of cervical cancer over time, specifically in the proportion of patients over 65 years old, given decreasing rates of hysterectomy. MATERIALS AND METHODS: A retrospective review of a single institution was conducted including cervical cancer patients seen between 1986 and 2016. Data included demographic variables including age of diagnosis, last cervical cancer screening, and cancer information. Cochran-Armitage test was used to assess temporal trends in the proportion of patients diagnosed over 65. RESULTS: A total of 1,019 patients with cervical cancer were reviewed, of whom 116 were over the age of 65. The age of diagnosis increased by 0.2 years per calendar year, with an average age of diagnosis of 43.7 years old in 1986 versus 49.5 years old in 2016 (p<0.01). The proportion of patients diagnosed with cervical cancer over the age of 65 did not significantly differ over time (17.2 % in 1986 vs. 14.8 % in 2016, p=0.39). 19.0 % of women diagnosed with cervical cancer over the age of 65 developed cancer despite exiting screening appropriately. CONCLUSIONS: In our cohort, the age of diagnosis of cervical cancer increased over time, however, there was no significant difference in the percentage of women diagnosed over the age of 65.

RESUMO

OBJECTIVES: The aims of the study were to identify whether obese women are less appropriately screened for cervical cancer before diagnosis and to explore related cancer outcomes. METHODS: We retrospectively reviewed all cervical cancer patients at a single institution between 1986 and 2016 and collected demographic information including age, cancer stage, body mass index (BMI), screening information, and cancer outcomes. Morbid obesity was defined as BMI of 40 kg/m or greater, obesity as BMI of 30 to less than 40 kg/m, and nonobese as BMI of less than 30 kg/m. χ, Fisher exact, and Wilcoxon rank sum tests were used to compare variables between BMI categories. Cox regression models were used to evaluate recurrence-free survival and overall survival (OS). RESULTS: A total of 1,080 patients were reviewed, of whom 311 (29.4%) were obese and 107 (10.1%) morbidly obese. A significant association between BMI and cytology screening was evidenced with morbidly obese women having the highest incorrect rate (64.4%), followed by obese (51.5%) and nonobese women (46.0%, p < .01). There was no significant difference in presence of symptoms at presentation (p = .12) or stage (p = .06) between BMI categories. In multivariable analysis of cancer outcomes, higher BMI was associated with worse OS (p < .01) with a hazard ratio of 1.25 (95% CI = 0.92-1.69) for obese women and hazard ratio 2.27 (95% CI = 1.56-3.31) for morbidly obese women relative to normal weight but recurrence-free survival did not differ between BMI groups (p = .07). CONCLUSIONS: Our study strengthens evidence that obese and morbidly obese women have disproportionate inappropriate screening before cervical cancer diagnosis, and morbidly obese women have worse OS than their counterparts.

RESUMO

STUDY OBJECTIVE: To compare the parenting and career patterns of female and male gynecology subspecialists. DESIGN: Cross-sectional survey study (Canadian Task Force classification II-3). SETTING: Survey administered electronically in February 2015 to physician members of the Society of Gynecologic Oncology, the American Society for Reproductive Medicine, and the American Urogynecologic Society. PARTICIPANTS: All physician members of the 3 national gynecology subspecialty organizations listed above. MEASUREMENTS AND MAIN RESULTS: There were 75 questions in 4 domains: demographics, mentoring issues, work-life balance, and caregiving responsibilities. Data were analyzed for survey sampling weights. Six hundred seventy-seven physicians completed the survey, 62% of whom were women (n = 420; 20.2% response rate). Sixty-four percent were aged 36 to 55 years. Eighty-two percent of respondents had at least 1 child, and men had more children than women (42% of men had 3 or more children compared with 20% of women, p <.0001). Thirty-seven percent of women reported that career plans affected the decision to become a parent somewhat or very much compared with 23% of men (p = .0006). Eighty-three percent of women believed career affected the timing of becoming a parent somewhat or very much compared with 48% of men (p <.0001). In addition, 76% of female physicians perceived that having children decreased their academic productivity compared with 54% of male physicians (p <.0001). Most men and women believed having children had no effect or increased their clinical performance (76% and 65%, respectively), but this was significantly lower in women (p = .01). CONCLUSION: Female gynecology subspecialists perceive that their career impacted decisions on parenting more frequently than their male counterparts. They were also more likely than men to report that having children had a negative impact on academic and, to a lesser extent, clinical performance. Increased support for combining childbirth and parenting with training and academic careers is needed.

RESUMO

Nanoparticles have been used as diagnostic and therapeutic agents in the human medical field for quite some time, though their application in veterinary medicine and animal production is still relatively new. Recently, production demands on the livestock industry have been centered around the use of antibiotics as growth promoters due to growing concern over microbial antibiotic resistance. With many countries reporting increased incidences of antibiotic-resistant bacteria, laws and regulations are being updated to end in-feed antibiotic use in the animal production industry. This sets the need for suitable alternatives to be established for inclusion in feed. Many reports have shown evidence that nanoparticles may be good candidates for animal growth promotion and antimicrobials. The current status and advancements of nanotechnological applications in animal production will be the focus of this review and the emerging roles of nanoparticles for nutrient delivery, biocidal agents, and tools in veterinary medicine and reproduction will be discussed. Additionally, influences on meat, egg, and milk quality will be reviewed.

RESUMO

OBJECTIVE: To estimate whether there is a gender difference in scholarly productivity among academic gynecologic oncologists. METHODS: In this cross-sectional study, the academic rank and gender of gynecologic oncology faculty in the United States were determined from online residency and fellowship directories and departmental web sites. Each individual's h-index and years of publication were determined from Scopus (a citation database of peer-reviewed literature). The h-index is a quantification of an author's scholarly productivity that combines the number of publications with the number of times the publications have been cited. We generated descriptive statistics and compared rank, gender, and productivity scores. RESULTS: Five hundred seven academic faculty within 137 U.S. teaching programs were identified. Of these, 215 (42%) were female and 292 (58%) were male. Men had significantly higher median h-indices than women, 16 compared with 8, respectively (P<.001). Women were more likely to be of junior academic rank with 63% of assistant professors being female compared with 20% of full professors. When stratifying h-indices by gender and academic rank, men had significantly higher h-indices at the assistant professor level (7 compared with 5, P<.001); however, this difference disappeared at the higher ranks. Stratifying by the years of active publication, there was no significant difference between genders. CONCLUSION: Female gynecologic oncologists at the assistant professor level had lower scholarly productivity than men; however, at higher academic ranks, they equaled their male counterparts. Women were more junior in rank, had published for fewer years, and were underrepresented in leadership positions. LEVEL OF EVIDENCE: III.

RESUMO

AIM: To investigate the in vivo effects of 3-indolylmethanamines 31B and PS121912 in treating ovarian cancer and leukemia, respectively. MATERIALS AND METHODS: Terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) and western blotting were applied to demonstrate the induction of apoptosis. Xenografted mice were investigated to show the antitumor effects of 3-indolylmethanamines. (13)C-Nuclear magnetic resource (NMR) and western blotting were used to demonstrate inhibition of glucose metabolism. RESULTS: 31B inhibited ovarian cancer cell proliferation and activated caspase-3, cleaved poly (ADP-ribose) polymerase 1 (PARP1), and phosphorylated mitogen-activated protein kinases (MAPK), JUN N-terminal kinase/stress-activated protein kinase (JNK/SAPK) and p38. 31B reduced ovarian cancer xenograft tumor growth and PS121912 inhibited the growth of HL-60-derived xenografts without any sign of toxicity. Compound 31B inhibited de novo glycolysis and lipogenesis mediated by the reduction of fatty acid synthase and lactate dehydrogenase-A expression. CONCLUSION: 3-Indolylmethanamines represent a new class of antitumor agents. We have shown for the first time the in vivo anticancer effects of 3-indolylmethanamines 31B and PS121912.

RESUMO

Selective overexpression of Human epididymal secretory protein E4 (HE4) points to a role in ovarian cancer tumorigenesis but little is known about the role the HE4 gene or the gene product plays. Here we show that elevated HE4 serum levels correlate with chemoresistance and decreased survival rates in EOC patients. HE4 overexpression promoted xenograft tumor growth and chemoresistance against cisplatin in an animal model resulting in reduced survival rates. HE4 displayed responses to tumor microenvironment constituents and presented increased expression as well as nuclear translocation upon EGF, VEGF and Insulin treatment and nucleolar localization with Insulin treatment. HE4 interacts with EGFR, IGF1R, and transcription factor HIF1α. Constructs of antisense phosphorothio-oligonucleotides targeting HE4 arrested tumor growth in nude mice. Collectively these findings implicate increased HE4 expression as a molecular factor in ovarian cancer tumorigenesis. Selective targeting directed towards the HE4 protein demonstrates therapeutic benefits for the treatment of ovarian cancer.

RESUMO

While early-stage endometrial cancer is often successfully treated with surgical intervention, treatment of advanced endometrial carcinoma can be difficult and prognosis poor, particularly in the context of metastatic or recurrent disease. Standard chemotherapy agents for both adjuvant first-line treatment (for selected patients deemed at high risk of relapse) and recurrent endometrial cancer include doxorubicin, platinum agents and paclitaxel. Investigational options currently being studied in phase II trials include both combined regimens of standard chemotherapeutic agents versus radiation as well as targeted treatments such as epothilones, mammalian target of rapamycin (mTOR) inhibitors and anti-angiogenic agents. Recent interest in the molecular pathways of carcinogenesis have lead to increased investigation of these novel agents and the hope that they will impact positively on the overall survival of women with endometrial cancer.

RESUMO

OBJECTIVE: To develop a nomogram based on established prognostic factors to predict the probability of 5-year disease-specific mortality after primary surgery for patients with all stages of epithelial ovarian cancer (EOC) and compare the predictive accuracy with the currently used International Federation of Gynecology and Obstetrics (FIGO) staging system. METHODS: Using a prospectively kept database, we identified all patients with EOC who had their primary surgery at our institution between January 1996 and December 2004. Disease-specific mortality was estimated using the Kaplan-Meier method. Twenty-eight clinical and pathologic factors were analyzed. Significant factors on univariate analysis were included in the Cox proportional hazards regression model, which identified factors utilized in the nomogram. The concordance index (CI) was used as an accuracy measure, with bootstrapping to correct for optimistic bias. Calibration plots were constructed. RESULTS: A total of 478 patients with EOC were included. The most predictive nomogram was constructed using seven variables: age, FIGO stage, residual disease status, preoperative albumin level, histology, family history suggestive of hereditary breast/ovarian cancer (HBOC) syndrome, and American Society of Anesthesiologists (ASA) status. This nomogram was internally validated using bootstrapping and shown to have excellent calibration with a bootstrap-corrected CI of 0.714. The CI for FIGO staging alone was significantly less at 0.62 (P=0.002). CONCLUSION: We have developed an all-stage nomogram to predict 5-year disease-specific mortality after primary surgery for epithelial ovarian cancer. This tool is more accurate than FIGO staging and should be useful for patient counseling, clinical trial eligibility, postoperative management, and follow-up.

RESUMO

BACKGROUND: The objective of this study was to identify patterns of interest in receiving care for sexual concerns among women who were survivors of gynecologic and breast cancers. METHODS: Survey and medical records data were collected from June 2008 to March 2009 from 261 gynecologic and breast cancer patients. Logistic regression was used to estimate the effect of age and months since treatment on interest in receiving sexual healthcare. RESULTS: The mean participant age was 55 years (range, 21-88 years). Only 7% of women had recently sought medical help for sexual issues, yet 41.6% were interested in receiving care. Greater than 30% responded that they would be likely to see a physician to address sexual matters, and 35% of all women were willing to be contacted if a formal program was offered. Compared with older women (aged >65 years), younger women (ages 18-47 years) were significantly more likely to report interest in receiving care to address sexual issues (odds ratio [OR], 2.94; 95% confidence interval [CI], 1.14-7.54) and to see a physician to address sexual matters (OR, 4.51; 95% CI, 1.51-13.43), and they were more willing to be contacted for a formal program (adjusted OR [AOR], 5.00; 95% CI, 1.63-15.28). Compared with women who were currently in treatment, women who last received treatment >12 months previously were significantly more interested in receiving care (AOR, 2.02; 95% CI, 1.02-4.01) and were more willing to be contacted (AOR, 2.49; 95% CI, 1.18-5.26). CONCLUSIONS: Greater than 40% of survivors expressed interest in receiving sexual healthcare, but few had ever sought such care. The current results indicated that there is an unmet need for attention to sexual concerns among women with gynecologic and breast cancers.
