Endogenous retrovirus RNA expression differences between race, stage and HPV status offer improved prognostication among women with cervical cancer
Endogenous human retroviruses (ERVs) are remnants of exogenous retroviruses that have integrated into the human genome. Using publicly available RNA-seq data from 63 cervical cancer patients, we investigated the expression of ERVs in cervical cancers. Four aspects of cervical cancer were investigated: patient ancestral background, tumor HPV type, tumor stage and patient survival. Between the racial subgroups, 74 ERVs were significantly differentially expressed, with Black Americans having 30 upregulated and 44 downregulated (including MER21C, HERV9-int, and HERVH-int) ERVs when compared to White Americans. We found that 3313 ERVs were differentially expressed between HPV subgroups, including MER41A, HERVH-int and HERVK9. There were 28 downregulated (including MLT1D and HERVH-int) and 61 upregulated (including MER41A) ERVs in locally advanced-stage compared to early-stage samples. Tissue microarrays of cervical cancer patients were used to investigate the protein expression of ERVs with protein coding potential (i.e., HERVK and ERV3). Significant differences in protein expression of ERV3
IL2 Inducible T-cell Kinase, a Novel Therapeutic Target in Melanoma
Interleukin-2 inducible T-cell kinase (ITK) promoter CpG sites are hypomethylated in melanomas compared to nevi. The expression of ITK in melanomas, however, has not been established and requires elucidation

Clinical Trials of Antiangiogenesis Therapy in Recurrent/Persistent and Metastatic Cervical Cancer
BACKGROUND. Treatment options for women with metastatic, persistent, or recurrent cervical cancer are limited and thus the disease portends a poor prognosis. It is critical to understand the pathophysiology of cervical cancer to better delineate therapeutic targets. The development of antiangiogenic therapies and their subsequent analysis in rigorous therapeutic trials have redefined current management strategies and is an exciting area of current exploration. RESULTS. Translational trials have furthered the understanding of molecular determinants of angiogenesis. Phase II trials have shown promising trends with developing antiangiogenic therapies. A practice-changing phase III trial has recently been published. Given the potential benefits and different toxicity spectrum compared with standard cytotoxic chemotherapy, antiangiogenic options are under active investigation for this vulnerable patient population. Emerging data are promising for other antiangiogenic-directed therapeutics, as well as cervical cancer molecular biomarkers to guide diagnosis and treatment. CONCLUSION. Antiangiogenic therapies have evolved during the past 20 years and remain an exciting area of current exploration. IMPLICATIONS FOR PRACTICE: Understanding of the angiogenic microenvironment has furthered understanding of tumor biology and management. Antiangiogenic therapies show promise for women with advanced cervical cancer. A review of the evolution of these biologic agents shows them to be an effective and tolerable management strategy for many patients in this vulnerable population, with exciting future potential
The impact of adjuvant antihormonal therapy versus observation on recurrence of borderline ovarian tumors: A retrospective cohort study
Objectives: Adjuvant management of borderline ovarian tumors (BOT) after surgical diagnosis and staging is not standardized. While many patients undergo observation alone, some providers have introduced the use of adjuvant antihormonal therapy for BOT, extrapolating from studies suggesting improvement in progression-free survival in the low-grade serous ovarian carcinoma population. We hypothesized that adjuvant antihormonal therapy after surgical diagnosis of BOT would improve progression-free survival compared to surveillance alone. Methods: This is a retrospective review of BOT at one academic institution over thirteen years comparing management with antihormonal therapy, including aromatase inhibitors, progestins, and selective estrogen receptor modulators, to surveillance alone. Patients with concurrent malignancy were excluded. Data were abstracted from electronic medical records. Groups were compared by bivariate statistics. Results: We identified 193 patients with BOT. Of these, 17 (8.8%) were treated with adjuvant antihormonal therapy and 24 (12.4%) recurred. Patients treated with antihormonal therapy were more likely to be obese (64.7% vs 37.9%, p = 0.032), have advanced-stage disease (70.6% vs 11.4%, p < 0.001), serous histotype (94.1% vs 59.4%, p = 0.005) or microinvasion (29.4% vs 9.7%, p = 0.030), and less likely to have undergone fertility-sparing surgery (18.8% vs 51.7%, p = 0.012). Use of antihormonal therapy was not associated with a difference in recurrence or survival. Conclusions: This study is the first retrospective cohort review of adjuvant antihormonal therapy in BOT. We found that adjuvant antihormonal therapy for BOT is not associated with recurrence. While this single institution retrospective cohort study may lack the power to confirm or refute benefit, further studies could evaluate whether a subpopulation exists in whom antihormonal therapy is worthwhile

Prevalence and predictors of HIV screening in invasive cervical cancer: a 10 year cohort study
BackgroundInvasive cervical carcinoma is associated with a human immunodeficiency virus (HIV) prevalence of >0.1%, and screening is recommended and cost-effective for cancer populations exceeding this threshold. HIV status is also prognostic for cancer-specific survival, but compliance with HIV screening is poor in the USA and abroad.ObjectivesThis study aims to describe HIV screening practices in a US comprehensive cancer center. To guide quality improvement, we identify characteristics which may predict compliance with screening.Study designWomen treated for invasive cervical cancer from January 2007 to December 2017 were identified by local cancer registry and billing data. We assessed age, race, ethnicity, insurance status, histology, stage, pregnancy, drug use, and HIV testing status. Univariate logistical regression was performed to assess predictors of completed HIV screening.ResultsOf 492 eligible women, the cumulative screening rate was 7.6%. Race, ethnicity, histology, and funding source were not predictive of screening. Every 5 year increase in age was associated with a lower chance of screening (OR 0.86, p=0.015), as was earlier stage at diagnosis (OR 0.43, p=0.017). Pregnancy during, or antecedent to, invasive cervical cancer diagnosis was significantly more predictive of screening compliance (OR 10.57, p=0.0007). Only 8/492 (1.6%) women in the cohort were active or former drug users, but within this group HIV screening was performed more frequently (OR 22.7, p<0.0001).ConclusionDespite US and international recommendations for HIV screening in AIDS-defining cancers, compliance remains low. In our centers, factors including earlier age, advanced stage, active pregnancy at diagnosis, and any drug use history were predictive of greater compliance with screening. These data will inform a tailored intervention to improve compliance with HIV screening in our population
