11013 Background: A high prevalence of gender discrimination and harassment has been described among gynecologic oncologists (GOs). This study examined the work environment for women GOs and delineated the perpetrators of negative behaviors. Methods: An internet-based, IRB exempt survey of members of a 472-member Facebook group “Women of Gynecologic Oncology (WGO)” was conducted. Using REDcap survey platform, members provided demographics, practice infrastructure, personal experience with workplace bullying, gender discrimination, microaggressions, and outcomes. Demographic, practice and work environments and perpetrators of negative behaviors were summarized using descriptive statistics. Results: Between 7/20 and 8/19/2020, 250 (53%) of active WGO members participated in this survey. Most respondents were younger than 50 years old (93.6%); white (82.2%) and non-Hispanic (94.3%). A majority were married (84.7%) with children (75.2%). Practice environments included academic (152, 61.0%), private practice (31, 12.4%), and hospital employed (57, 22.9%). 89.9% supervised trainees. 130 (52.0%) respondents reported bullying, 140 (56.0%) gender discrimination, and 83% having experienced gender-based microaggressions. Age, race, ethnicity, practice setting, division director or chair gender or department reporting structure were not significantly associated with these experiences. Perpetrators of bullying, gender discrimination, and microaggressions were widely distributed (Table). Of those reporting bullying, 61 (46.6%) reported a male perpetrator, 25 (19.1%) female and 45 (34.4%) an equal gender distribution; of those reporting discrimination 105 (74.5%) reported a male perpetrator, 9 (6.4%) female and 27 (19.1%) an equal gender distribution. 32.9% of survey respondents acknowledged having been written up for speaking up in a way that would have been tolerated from a male colleague. 18.3% of respondents have changed jobs because of bullying; 13.5% because of discrimination. Conclusions: Women GOs report high rates of workplace bullying, gender discrimination, and microaggressions regardless of practice setting that often impact their careers. Perpetrators of these behaviors are multiple and varied. Proactive and deliberate interventions to improve the work environments for women GOs are urgently needed.[Table: see text]

6044 Background: Human cytomegalovirus (CMV) infection induces a subset of long-lived CD57+NKG2C+ adaptive NK cells that exhibit enhanced antibody-dependent cellular cytotoxicity and resistance to tumor-suppressive mechanisms. We developed a 7-day culture process using a GSK3 inhibitor and IL-15 to manufacture modulated adaptive NK cells (FATE-NK100) from CMV+ haploidentical donors for adoptive transfer. The phase I Apollo trial tests the maximum tolerated dose/maximum feasible dose (MTD/MFD) of FATE-NK100 administered intraperitoneally (IP) to treat platinum-sensitive or -resistant recurrent ovarian, fallopian tube, and primary peritoneal cancer. Methods: FATE-NK100 via IP port was tested using 3 dose cohorts ([DC]; 1 × 107 cells/kg; >1 × 107 cells/kg to ≤3 × 107 cells/kg; or >3 × 107 to ≤10 × 107 cells/kg) after lympho-conditioning with fludarabine 25 mg/m2 IV and cyclophosphamide 300 mg/m2 IV on days −6 and −5. After FATE-NK100 infusion on day 0, rhIL-2 at 6 million IU was given IP 3 times a week for 6 doses for in vivo NK activation. IP fluid and peripheral blood were collected regularly until response assessment (day 28). Patients with stable disease or better were eligible for retreatment. Pre- and post-treatment tumor biopsies were collected. Results: Nine patients were treated with no dose-limiting toxicities (DLTs) to date. Retreatment based on clinical benefit was performed on 3 patients (33%), 2 following stable disease (DC 2) and 1 with partial remission (48% tumor reduction, DC 3). IP samples were collected for PK and functional analysis. FATE-NK100 product was detected by flow cytometry in 5 of 6 patients with evaluable samples (range 4.8%–91.2% donor NK cells at day +5-7). Retreatment samples were available in 1 patient, where FATE-NK100 persisted to day +21, demonstrating that repeated IP dosing did not accelerate clearance of the donor NK cells. In that same patient, measurement of NK cell CD107a degranulation or IFNg production in response to K562 targets demonstrated sustained enhanced in vivo function of FATE-NK100 compared to endogenous patient NK cells (e.g. at Day +12 CD107a+ NK were 39.0% vs. 22.5% cycle 1, and 40.3% vs. 18.2% retreatment cycle 2, and IFNg+ NK were 12.3% vs. 5.9% cycle 1, and 2.4% vs. 0.2% retreatment cycle 2). Conclusions: IP delivery of FATE-NK100 is safe, with clinical benefit in 3/9 patients treated. The allogeneic product cells persist and have enhanced function compared to patient NK cells for up to 21 days, even after retreatment. This phase I study in recurrent/refractory ovarian cancer shows promise for IP NK cell delivery. Clinical trial information: NCT00652899.

5581 Background: Platinum chemotherapy resistance occurs in approximately 25% of patients with ovarian carcinoma and represents a major barrier to effective care of this patient population. To date there are no effective nor validate predictive biomarkers of chemoresistance of ovarian carcinomas. We performed a prospective trial designed to enroll patients with ovarian masses suspicious for ovarian cancer, with the goal of identifying tumor-based predictive biomarkers of platinum resistance. Methods: 60 women were enrolled on the study. Tumor specimens were collected from 49 of these women with newly diagnosed pelvic masses, of which 29 were found to have histopathologically proven primary ovarian carcinoma. Of these primary malignant cases, 24 had specimens accessible for assessment of tumor-stroma proportion and data available regarding chemosensitive vs chemoresistance status via review of the medical record using a UMN IRB-approved protocol. Tumor slices were stained with H&E and also for antibodies against two microRNAs (29b and 199a) differentially expressed in ovarian cancer cell lines. Tumor-stroma proportions were assessed by two experienced pathologists blinded to chemoresistance status, with 50% scored as high proportion. Results: The average age of assessed patients with malignant tumors was 62. 87.5% had high-grade epithelial carcinomas. Baseline median CA-125 was 416 (range 32-2782). 80% of ovarian cancer patients with chemoresistance had tumor stroma proportions >50%; 73.7% of cancer patients with chemosensitive tumors had proportions

e23180 Background: Psychosocial outcomes have been described in women with gynecological cancers, but potential differences by diagnosis have received less attention. We sought to compare quality of life (QOL) and emotional health among early stage gynecological cancer survivors by disease location. Methods: We present baseline data from an ongoing cohort study of gynecological cancer patients treated at an academic cancer center. Measures include cancer-related QOL, emotional health and negative (post-traumatic stress disorder-PTSD) and positive (post-traumatic growth-PTG) reactions to cancer. Univariate and multivariate linear regression models (restricted to stage I or II; excluding vaginal/vulvar) explored differences in QOL and emotional health by diagnosis. Potential confounders considered for inclusion in the final models were age, stage, education, income, partner status, treatment status, and race. Results: 222 patients with early stage disease completed the survey: 56 (25.2%) ovarian, 122 (55.5) endometrial, 33 cervical (14.9%), and 11 (5%) vaginal/vulvar cancer. Cervical and vaginal/vulvar cancer patients reported greater cancer-related distress, anxiety and PTSD scores (Table). Endometrial cancer patients reported lowest PTG scores. Conclusions: Our analyses suggest early stage gynecological cancer patients face different psychosocial sequelae based on diagnosis, with worse outcomes generally being associated with younger age. Further research is needed to assess low PTG among endometrial cancer patients, since PTG is considered a potentially beneficial psychosocial outcome of cancer. [Table: see text]

e13037 Background: Breast cancer screening guidelines disagree on the age to initiate and discontinue screening. We sought to determine the age at which Minnesota providers initiate and discontinue breast cancer screening. Methods: A cross-sectional online survey of Minnesota primary care providers was conducted in 2016. The survey queried providers’ breast screening practices for average-risk women. Data were summarized using descriptive statistics and comparisons by professional characteristics were conducted using Chi-squared tests. Results: There were 805 respondents (8% of 10,392 invitees), of which 456 (56.7%) provided primary care to women and were included in the analysis. 316 (72%) were women, 193 (44%) were physicians, 50 (11%) were physician assistants (PAs), and 197 (45%) were advanced practice nurses (APNs). 85% practiced in a community setting. 38% had practiced > 20 years, and 27% had practiced < 10 years. Among respondents, 67%, 77% and 72% recommended screening mammography for women age 40-44, 45-49 and 70+ years, respectively. Compared to male providers, female providers were more likely to screen women age 40-44 years (73% vs. 49%; p < 0.0001) and 45-49 years (81% vs. 66%; p = 0.002), but there was no difference by gender for patients age 70+ years (72% vs. 74%; p = 0.89). Respondents reporting specialized interest in women’s health were more likely to screen women age 40-44 years (73% vs. 61%; p = 0.006), 45-49 years (83% vs 72%; p = 0.007) and older than age 70 years (77% vs. 69%; p = 0.04). Physicians were less likely to screen women age 40-44 and 45-49 years (57% and 71%, respectively; p = 0.001) than PAs (72%, 78%) and APNs (74%, 83%), but APNs were less likely to screen women age 70+ years (65% vs. physicians 79% vs. PAs 76%; p = 0.006). Number of years in practice was not associated with a difference in age at initiation of screening, however, increasing number of years in practice was associated with screening women age 70+ years (p = 0.02). Conclusions: Although breast cancer screening practices for average risk women vary by healthcare provider characteristics, a majority of Minnesota primary care providers initiate breast cancer screening between ages 40-49 years, and continue screening women age 70 years and older.

1550 Background: Little literature exists on primary care providers’ knowledge and preferences towards breast cancer screening for high-risk women. While guidelines recommend MRI and mammography, it is unclear how frequently these recommendations are used. Methods: This web-based survey of providers licensed to practice in Minnesota was conducted. This analysis focuses on breast cancer screening practices for high-risk women. Data were summarized using descriptive statistics; professional characteristic comparisons were conducted using Chi-squared tests. Results: 805 of 10,392 (8%) invitees completed the survey. 72.2% were female. 43.9% were physicians (20.8% internists, 71.7% family medicine, 6.3% gynecology), 11.4% physician assistants (PAs), 44.8% advanced practice registered nurses (APRNs). 84.8% were in community practice, 38% > 20 years of experience and 27.1% < 10 years. When asked how effective screening was for reducing cancer mortality in high risk women, mammography was thought to be very effective (48.8%) or effective (46.8%) in women ages 40-49 years, for women ages 50+ years, 60.8% and 35.7%, respectively. 62.4% thought breast MRI was very effective in reducing cancer mortality in high risk women. There was no difference in breast MRI recommendation based on professional background, experience or practice setting. Female practitioners, less experience, and those working in gynecology or women’s health were more likely to recommend breast MRI. A case vignette for high risk screening cancer survivors is provided (Table). Conclusions: Most primary care providers believe mammography is helpful in women at high risk for developing breast cancer. Less than half of practitioners, however, are following guideline specific recommendations of both mammography and MRI for breast cancer screening in high-risk patients. [Table: see text]

193 Background: Cervical cancer is the most prevalent gynecologic cancer worldwide, but is third in the U.S. due to pap smear screening. However, American Society for Colposcopy and Cervical Pathology (ASCCP) guidelines are complex and frequently changed, resulting in guideline adherence as low as 33-44%. We describe a centralized pap smear tracking system (“pap hub”) and report preliminary results. Methods: On 1/1/13 we implemented the pap hub, routing all screening pap smear results to a dedicated OB/Gyn nursing staff with a new Epic workbench. Epic Health Maintenance Modifier updated to recommend pap smears for women age 21-65 years (not younger or older per guidelines). Screening Pap/HPV results auto routed to Pap Pool Epic inbasket (not to individual providers). Centralized nurse reviews results alongside past pap results on Pathology flowsheet in Epic If normal Normal history -> appropriate follow-up interval per screening guidelines If abnormal history -> repeat pap as determined by previous history and treatment If abnormal -> manage per ASCCP guidelines Document plan in Epic Result Note Update Epic problems list If Normal: document “Pap Hub Normal History” If Abnormal: document “Pap Hub Abnormal History” with specifics in Overview History Communicate results/plan to the patient. Update Health Maintenance Modifier with next step. Review abnormal results to ensure proper follow-up, with reminders as indicated. Results: Guideline recommendations against pap smears for patients 65 years have not changed since 2009. Comparison of first-quarter data for 2010 (pre-Pap Hub) to 2013 (post-Pap Hub) have shown a 63.86% reduction in pap smears in women 65 years has always been low, but has decreased slightly from 2.4% of all pap smears in 2010 to 1.5% of all pap smears in 2013. The 2012 ASCCP guidelines have changed recommended pap smear frequency and abnormal pap smear follow-up, and compliance with these new recommendations is being collected. Conclusions: Pap smear screening has decreased the incidence of invasive cervical cancer in the United States. The Pap Hub, a centralized pap smear tracking system, improves compliance with pap smear screening guidelines.
