    Abstract Objective: We studied cis-women with uterine cancer presenting to the two Public Hospitals in Queens, New York from 2006 to 2015 to examine the relationship between nativity (birthplace) and survival.
    Methods: A retrospective review of tumor registries identified women diagnosed with uterine cancer between January 1, 2006, and December 31, 2015. Data from 259 women were available for this analysis.
    Results: Most women were born outside the United States (US) (76% versus 24%). The majority of US-born women were black (68%). Seventy-seven women (30%) were born in Latin America, 76 in the Caribbean Islands (29%) and 44 in Asia/South Asia (17%). Most women presented with stage I/II disease (70%) and endometrioid/mucinous histology (68%) with no significant differences observed among nativity groups. Kaplan-Meier estimated survival curves stratified by birthplace demonstrated significant differences in survival distributions among the groups using the log-rank test (P < 0.0001). The most favorable survival curves were observed among all foreign-born women, whereas the least favorable survival was demonstrated in US-born women. Time to death was analyzed using the Cox proportional hazards model. Adjusting for age of diagnosis, insurance status, stage, and treatment modality, Latin American and Asia/South Asia birthplace was significantly associated with increased survival time.
    Conclusion: An immigrant health paradox was defined for foreign-born Latin American and Asian/South Asian women presenting to the two Public Hospitals of Queens, New York, as women born in these geographic regions were less likely to die at any given time compared to those born in the United States.

    Abstract Although the progressive histologic steps leading to endometrial cancer (EndoCA), the most common female reproductive tract malignancy, from endometrial hyperplasia are well-established, the molecular changes accompanying this malignant transformation in a single patient have never been described. We had the unique opportunity to investigate the paired histologic and molecular features associated with the 12-yr development of EndoCA in a postmenopausal female who could not undergo hysterectomy and instead underwent progesterone treatment. Using a specially designed 58-gene next-generation sequencing panel, we analyzed a total of 10 sequential biopsy samples collected over this time frame. A total of eight pathogenic/likely pathogenic mutations in seven genes,

    Abstract Background: Epithelial ovarian cancer has the highest fatality rate of all gynecologic malignancies. Although the majority of patients achieve complete clinical response after initial cytoreductive surgery and platinum-based chemotherapy, most recur and almost all will eventually acquire platinum-resistance for which treatment options become limited. The objective of the study was to describe response and tolerability of metronomic chemotherapy regimen GFIP/BDC, a modification of the G-FLIP regimen, in patients with persistent or recurrent epithelial ovarian, fallopian tube, and primary peritoneal cancer.
    Methods: A retrospective descriptive analysis of 20 patients from a single academic institution who received combination GFIP/BDC therapy from January 1, 2011 to August 31, 2016 for persistent or recurrent EOC/FT/PP. Treatment consisted of a 2-day combination of gemcitabine 300 mg, 5-fluorouracil 500 mg/m2, irinotecan 20-30 mg/m2, cisplatin 20 mg/m2, bevacizumab 4 mg/kg, docetaxel 20 mg/m2, and cyclophosphamide 200 mg/m2 administered every 14 days. Toxicities were retrospectively graded using CTCAE v4.0.
    Results: Twenty patients were identified with a median age 57.5 years (range 32-71). A total of 85% of patients were non-Hispanic white, 90% had cancer of high-grade serous histology, and all had a GOG performance status of 0-1. Patients had received a median of 3 prior regimens and 95% were platinum-resistant. Median number of cycles of GFIP/BDC administered was 9 (range 3-48) and patients remained on treatment for a median of 5.1 months (range 1.5-24). Eleven patients (55%) experienced a partial clinical response with a median duration of 6 months (range 1.5-20). Six patients (30%) survived progression free for at least 6 months. Ten patients (50%) experienced at least one grade 3/4 adverse event. Grade 3 adverse events were hematologic (n = 5), constitutional (n = 3), gastrointestinal (n = 3), neurologic (n = 2), and vascular (n = 1). There was only one grade 4 adverse event which was severe neutropenia. Patients discontinued treatment due to disease progression 65% (n = 13), toxicity 20% (n = 4), patient preference 10% (n = 2), and 5% (n = 1) is currently on treatment.
    Conclusions: Selected patients with epithelial ovarian, fallopian tube or primary peritoneal cancer who have failed multiple lines of conventional cytotoxic treatment may benefit from GFIP/BDC. Toxicity might be a limiting factor for administration.

    Abstract Objective: Endometrial cancer (EndoCA) is the most common gynecologic cancer and incidence and mortality rate continue to increase. Despite well-characterized knowledge of EndoCA-defining mutations, no effective diagnostic or screening tests exist. To lay the foundation for testing development, our study focused on defining the prevalence of somatic mutations present in non-cancerous uterine tissue.
    Methods: We obtained ≥8 uterine samplings, including separate endometrial and myometrial layers, from each of 22 women undergoing hysterectomy for non-cancer conditions. We ultra-deep sequenced (>2000× coverage) samples using a 125 cancer-relevant gene panel.
    Results: All women harbored complex mutation patterns. In total, 308 somatic mutations were identified with mutant allele frequencies ranging up to 96.0%. These encompassed 56 unique mutations from 24 genes. The majority of samples possessed predicted functional cancer mutations but curiously no growth advantage over non-functional mutations was detected. Functional mutations were enriched with increasing patient age (p = 0.045) and BMI (p = 0.0007) and in endometrial versus myometrial layers (68% vs 39%, p = 0.0002). Finally, while the somatic mutation landscape shared similar mutation prevalence in key TCGA-defined EndoCA genes, notably PIK3CA, significant differences were identified, including NOTCH1 (77% vs 10%), PTEN (9% vs 61%), TP53 (0% vs 37%) and CTNNB1 (0% vs 26%).
    Conclusions: An important caveat for future liquid biopsy/DNA-based cancer diagnostics is the repertoire of shared and distinct mutation profiles between histologically unremarkable and EndoCA tissues. The lack of selection pressure between functional and non-functional mutations in histologically unremarkable uterine tissue may offer a glimpse into an unrecognized EndoCA protective mechanism.

    Abstract At an HIV clinic in the Limpopo province of South Africa, chart reviews revealed long delays in addressing abnormal Pap smears, difficulty in referrals, poor quality and lost results, and increasing cases of cervical cancer. To address these barriers, a "see and treat" approach to screening was proposed. The objective was to integrate this method into current HIV care offered by local providers and to obtain demographic and risk factor data for use in future educational and intervention programs in the region. A cross sectional study of HIV farm workers and at-risk sex workers attending an HIV clinic was performed with visual inspection with acetic acid (VIA). Those with positive screens were offered cryotherapy. Clinic charts were reviewed retrospectively for Pap smear results for the previous year at the time of program initiation and at 12 and 18 months post-program. A total of 403 participants consented and underwent screening with VIA (306 Farm workers and 97 sex workers participated). 83.9% of participants (32.9% sex workers and 100% farm workers) were HIV +. VIA was positive in 30.5% of participants, necessitating cryotherapy. There was no significant difference in VIA positivity between HIV + farm workers and sex workers. There was a positive correlation between Pap smears and VIAs results. We demonstrate successful integration of cervical cancer screening using VIA for HIV + farm workers and sex workers into an existing HIV treatment and prevention clinic in rural South Africa, addressing and treating abnormal results promptly.

    Abstract Hyperthermic intraperitoneal chemotherapy (HIPEC) is a treatment modality that aims to target the main site of tumor dissemination in ovarian cancer, the peritoneum, by combining the benefits of intraperitoneal chemotherapy with the synergistic effects of hyperthermia all during a single administration at the time of cytoreductive surgery. High-quality evidence currently only supports the use of HIPEC with cisplatin at the time of interval cytoreduction after neoadjuvant chemotherapy for stage III epithelial ovarian cancer. Many questions remain, including HIPEC's role at other timepoints in ovarian cancer treatment, who are optimal candidates, and specifics of HIPEC protocols. This article reviews the history of normothermic and hyperthermic intraperitoneal chemotherapy in ovarian cancer and evidence regarding HIPEC implementation and patient outcomes. Additionally, this review explores details of HIPEC technique and perioperative care, cost considerations, complication and quality of life data, disparities in HIPEC use, and unresolved issues.

    Abstract Objective: To evaluate the inter- and intra-rater variability of lymphovascular space invasion (LVSI) in early stage cervical cancer.
    Methods: We identified invasive cervical cancer tissue samples from radical hysterectomies in our institutional pathology database. The cases were stained with Hematoxylin & Eosin (H&E) and immunostains (CD-31 and D2-40). They were evaluated for the presence of LVSI by 6 pathologists on 3 separate occasions: with H&E staining only, then with H&E and immunostained specimens, and finally using a shared written criterion for diagnosis of LVSI. With 80 cases, a two-sided 95% confidence interval for the Kappa of 0.7 with a precision of 0.1 on each side was estimated.
    Results: Stage distribution was: IA 10%, IB 85%, and IIA 5%. The majority of cases were squamous cell carcinoma (55%), followed by adenocarcinoma (39%) and adenosquamous or other histology (6%). The mean inter-rater Kappa was 0.41 (95% CI: 0.37-0.45) for H&E. Usage of immunohistochemistry made a statistically significant improvement in the mean Kappa, but it still remained low: 0.52 (p = 0.02). Adding evaluation criteria for LVSI did not significantly increase the mean Kappa: 0.49 (p = 0.16). The mean intra-rater variability of H&E staining alone compared with H&E staining plus immunostaining was 0.53 (range: 0.43-0.64). The mean Kappa comparing H&E staining and H&E staining with criteria was 0.50 (range: 0.40-0.59).
    Conclusions: We noted high inter- and intra-rater variability in the diagnosis of LVSI underscoring the challenges of LVSI diagnosis. Considering the significance assigned to LVSI and its implication for treatment, comprehensive guidelines with regards to determination of LVSI status are of paramount importance.
