Abstract
Previous evidence indicates that human papillomavirus (HPV) integration status may be associated with cervical cancer development and progression. However, host genetic variation within genes that may play important roles in the viral integration process is understudied. The aim of this study was to examine the association between HPV16 and HPV18 viral integration status and SNPs in nonhomologous-end-joining (NHEJ) DNA repair pathway genes on cervical dysplasia. Women enrolled in two large trials of optical technologies for cervical cancer detection and positive for HPV16 or HPV18 were selected for HPV integration analysis and genotyping. Associations between SNPs and cytology (normal, low-grade, or high-grade lesions) were evaluated. Among women with cervical dysplasia, polytomous logistic regression models were used to evaluate the effect of each SNP on viral integration status. Of the 710 women evaluated [149 high-grade squamous intraepithelial lesion (HSIL), 251; low-grade squamous intraepithelial lesion (LSIL, 310 normal)], 395 (55.6%) were positive for HPV16 and 192 (27%) were positive for HPV18. Tag-SNPs in 13 DNA repair genes, including RAD50, WRN, and XRCC4, were significantly associated with cervical dysplasia. HPV16 integration status was differential across cervical cytology, but overall, most participants had a mix of both episomal and integrated HPV16. Four tag-SNPs in the XRCC4 gene were found to be significantly associated with HPV16 integration status. Our findings indicate that host genetic variation in NHEJ DNA repair pathway genes, specifically XRCC4, are significantly associated with HPV integration, and that these genes may play an important role in determining cervical cancer development and progression. PREVENTION RELEVANCE HPV integration in premalignant lesions and is thought to be an important driver of carcinogenesis. However, it is unclear what factors promote integration. The use of targeted genotyping among women presenting with cervical dysplasia has the potential to be an effective tool in assessing the likelihood of progression to cancer.

Abstract
Approximately 5% of cats in animal shelters in the United States test positive for either feline leukemia virus (FeLV) or feline immunodeficiency virus (FIV), which translates to more than 100,000 positive cats managed by shelters each year. Little is known about the current status of retroviral management in animal shelters, particularly in regions burdened by chronic pet overpopulation and high shelter admissions, such as the southern United States. The purpose of this study was to describe feline retroviral management in Florida shelters. Shelters were surveyed on practices including selection of cats for testing, diagnostic techniques, and outcome options for cats with positive test results. Responses were received from 139 of 153 animal shelters known to admit cats, including 55 municipal shelters (40%), 70 private shelters (50%), and 14 private shelters with municipal contracts (10%). A total of 115 shelters (83%) performed at least some testing, most using combination point-of-care devices for simultaneous FeLV antigen and FIV antibody screening. Of shelters that performed any testing, 56 (49%) tested all cats for FeLV and 52 (45%) tested all cats for both FeLV and FIV. The most common reason for testing was screening adoptable cats (108 shelters; 94%) and cats available for transfer to other organizations (78; 68%). Testing cats in trap-neuter-return/return-to-field programs was least common (21; 18%). Most common outcome options for positive cats included adoption (74; 64%), transfer (62; 54%), and euthanasia (49; 43%). Euthanasia following a positive test result was more common for cats with FeLV (49; 43%) than for cats with FIV (29; 25%) and was more common in municipal shelters, rural shelters, shelters taking in <500 cats a year, and shelters with overall live outcome rates for cats <70%. Although Florida shelter compliance with national guidelines for identification and management of FeLV and FIV positive cats was variable, most had live outcome options for at least some of their cats with positive test results. Increased access to training and practical programmatic tools may help more shelters implement cost-effective testing protocols, reduce risk for transmission to other cats, and support the best outcomes for this vulnerable population of cats.

Abstract
Spay/neuter identification tattoos and ear-tipping are simple and cost-effective methods to minimize the likelihood of unnecessary anesthesia and surgery in companion animals or the misidentification of sexually intact animals. This study assessed training of sterilization identifiers in US and Canadian veterinary schools and practitioner compliance with guidelines for identifiers via surveys conducted in 2019. Faculty in all 34 schools responded to the survey, reporting that curricula included sterilization identifiers in 31% of lecture-based training, 75% of spay/neuter laboratory-based training, and 38% of clinical practice-based training. A total of 425 facilities performing spay/neuter reported frequency and technical aspects of sterilization identifiers in client-owned and unowned (shelter, rescue, trap-neuter-return) animals. Facilities encountering large numbers of animals of unknown background, performing a high number of surgeries, or with specialized spay/neuter training were significantly more likely to use identifiers. Only 5% of private practices tattooed all owned animals, and 21% tattooed all unowned animals. In contrast, 80% of shelters and 72% of spay/neuter clinics tattooed all owned animals, and 84% of shelters and 70% of spay/neuter clinics tattooed all unowned animals. Green was the most common tattoo color (97%); the most common placement was near or in the incision for female cats (99%), female dogs (99%), and male dogs (92%), and ventral abdomen in male cats (55%). Enhanced training and implementation of best practices described in professional guidelines for sterilization identifiers are needed throughout the veterinary industry to protect animals from unnecessary procedures and to prevent unintended litters in animals misidentified as previously sterilized.

Abstract
By late April 2020, public discourse in the United States had shifted toward the idea of using more targeted case-based mitigation tactics (eg, contact tracing) to combat coronavirus disease 2019 (COVID-19) transmission while allowing for the safe "reopening" of society, in an effort to reduce the social, economic, and political ramifications associated with stricter approaches. Expanded tracing-testing efforts were touted as a key solution that would allow for a precision approach, thus preventing economies from having to shut down again. However, it is now clear that many regions of the United States were unable to mount robust enough testing-tracing programs to prevent major resurgences of disease. This viewpoint offers a discussion of why testing-tracing efforts failed to sufficiently mitigate COVID-19 across much of the nation, with the hope that such deliberation will help the US public health community better plan for the future.

Abstract
Background Various heartworm (HW) diagnostic testing modalities detect products of, or reactions to, different life cycle stages of Dirofilaria immitis. Microfilariae (Mf) can be directly visualized in blood, antigen (Ag) from immature and adult heartworms may be detected on commercial assays, and antibody (Ab) tests detect the host immune response to larval stages. Ag and Mf tests are commonly used in dogs, which frequently carry adult HW infections, but Ab tests have only been validated for use in cats. In some HW-infected dogs, Ag is blocked by immune complexing leading to false-negative results. Heat-treatment (HT) to disrupt these complexes can increase the sensitivity of HW Ag tests. The aim of this study was to compare different methods for diagnosing HW infection in dogs at high risk using individual and paired diagnostic tests, including an exploration of using Ab tests designed for cats to test canine samples. Methods One hundred stray adult (≥ 2-year-old) dogs in Florida shelters were tested using Mf, HW Ag, and HW Ab tests (feline HW Ab tests currently not commercially validated/approved for use in dogs); two versions of each test platform were used. Results Fourteen dogs tested positive using point-of-care (POC) Ag tests; an additional 2 dogs tested positive with microtiter well assay, and an additional 12 dogs tested positive using HT Ag testing. For individual tests, Ag test sensitivity/specificity compared to HT Ag was 50–57%/100%, and Ab tests were 46–64%/82–94%. Sensitivity estimates for individual tests were higher when comparing to non-HT Ag. Pairing POC Ag tests with Mf tests improved sensitivity without loss of specificity, while pairing POC Ag and Ab tests modestly increased sensitivity at the expense of specificity. Conclusions Screening dogs for HW infection using both POC Ag and Mf detection, which is recommended by the American Heartworm Society, improved diagnostic performance in this study compared to single Ag test use, but may have missed more than one in four infected dogs. The need to improve access to highly accurate, rapid, and inexpensive large-scale HW testing for dogs in animal shelters remains largely unmet by current testing availability. The development of practical and validated protocols that incorporate heat or chemical treatment to disrupt Ag-Ab complexes in POC testing or decreasing the cost and time required for such testing in reference laboratories might provide solutions to this unmet need. Similar studies performed in countries where the prevalence of parasites such as D. repens or A. vasorum is different to the USA could potentially yield very different positive predictive values for both HT and non-HT Ag tests.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has caused widespread mortality and morbidity. Though children are largely spared from severe illness, a novel childhood hyperinflammatory syndrome presumed to be associated with and subsequent to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has emerged with potentially severe outcomes. Multisystem inflammatory disorder in children (MIS-C) most commonly affects young, school-aged children and is characterized by persistent fever, systemic hyperinflammation, and multisystem organ dysfunction. While uncommon and generally treatable, MIS-C presents potentially life-altering medical sequelae, complicated by a dearth of information regarding its etiology, pathophysiology, and long-term outcomes. The severity of MIS-C may warrant the need for increased awareness and continued COVID-19 mitigation efforts, particularly until potential factors conferring a predisposition to MIS-C can be clarified through additional research. Well-informed guidelines will be critical as the school year progresses. In this article, current knowledge on MIS-C is reviewed and the potential implications of this novel syndrome are discussed from a public health perspective.

Abstract
Longitudinal studies of cats naturally infected with feline leukemia virus (FeLV) are important for understanding disease outcomes. Levels of p27 antigen and copy numbers of proviral DNA have been associated with FeLV-infection courses. The purpose of this prospective study was to establish cutoff values for p27 antigen concentration and proviral DNA load that distinguished high positive from low positive groups of cats and to evaluate an association with survival. At enrollment, 254 cats were tested by point-of-care and microtiter plate enzyme-linked immunosorbent assays (ELISAs) for p27 antigen and real-time polymerase chain reaction (PCR) for proviral DNA. The 127 positive cats were retested monthly for six months and monitored for survival over the four-year study. A receiver operating characteristic-based analysis of samples with concordant or discordant qualitative results for p27 antigen and proviral DNA was used to establish cutoff values, and when applied to test results at enrollment for classifying cats as high positive or low positive, a significant difference in survival was observed. High positive cats had a median survival of 1.37 years (95% CI 0.83-2.02) from time of enrollment, while most low positive cats were still alive (93.1% survival). Quantitative results for p27 antigen concentration and proviral DNA load were highly correlated with survival times in FeLV-infected cats.

Abstract
OBJECTIVES To assess the methodologies used in the estimation of diagnostic accuracy of SARS-CoV-2 real-time reverse transcription polymerase chain reaction (rRT-PCR) and other nucleic acid amplification tests (NAATs) and to evaluate the quality and reliability of the studies employing those methods. METHODS We conducted a systematic search of English-language articles published December 31, 2019-June 19, 2020. Studies of any design that performed tests on ≥10 patients and reported or inferred correlative statistics were included. Studies were evaluated using elements of the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) guidelines. RESULTS We conducted a narrative and tabular synthesis of studies organized by their reference standard strategy or comparative agreement method, resulting in six categorizations. Critical study details were frequently unreported, including the mechanism for patient/sample selection and researcher blinding to results, which lead to concern for bias. CONCLUSIONS Current studies estimating test performance characteristics have imperfect study design and statistical methods for the estimation of test performance characteristics of SARS-CoV-2 tests. The included studies employ heterogeneous methods and overall have an increased risk of bias. Employing standardized guidelines for study designs and statistical methods will improve the process for developing and validating rRT-PCR and NAAT for the diagnosis of COVID-19.

Abstract
Coronavirus disease 2019 (COVID-19) emerged in Hubei Province, China in December 2019 and has since become a global pandemic, with hundreds of thousands of cases and over 165 countries affected. Primary routes of transmission of the causative virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), are through respiratory droplets and close person-to-person contact. While information about other potential modes of transmission are relatively sparse, evidence supporting the possibility of a fecally mediated mode of transmission has been accumulating. Here, current knowledge on the potential for fecal transmission is briefly reviewed and the possible implications are discussed from a public health perspective.

Abstract
Recent international epidemics of coronavirus-associated illnesses underscore the urgent medical and public health need for vaccine development and regulatory body approved therapies. In particular, the current coronavirus disease 2019 (COVID-19) pandemic has quickly intensified interest in developing treatment options to mitigate impact on human life. Remdesivir (GS-5734™) is a broad-spectrum antiviral drug that is now being tested as a potential treatment for COVID-19 in international, multi-site clinical trials. Currently available evidence about the antiviral effects of remdesivir against coronaviruses is primarily based on in vitro and in vivo studies (including some on a chemically related compound, GS-441524™), which have demonstrated largely favorable findings. As the pandemic progresses, information from human compassionate use cases will continue to accumulate before the clinical trials are concluded. It is imperative for public health practitioners and the One Health community to stay up to date on the most promising potential therapeutic options that are under investigation. Thus, the purpose of this review is to synthesize the knowledge to date about remdesivir as a therapeutic option for coronaviruses, with a special focus on information relevant to the One Health community.

Abstract
Here, we present 11.5 years of monthly treatment statistics showing an overall intake of 5127 infected dogs between June 2008 and December 2019, as well as more detailed datasets from more recent, less protracted time periods for the examination of mortality risk, seasonality, and resource requirements in the mass treatment of canine parvovirus (CPV) in a private animal shelter. The total survival rate of animals during the study period was 86.6% (n = 4438/5127 dogs survived) with the probability of survival increasing to 96.7% after five days of treatment (with 80% of fatalities occurring in that period). A distinct parvovirus season peaking in May and June and troughing in August, September, December, and January was observed, which could have contributed as much as 41 animals peak-to-trough in the monthly population (with a potential, smaller season occurring in October). Low-weight and male animals were at higher risk for death, whereas age was not a significant contributing factor. Treatment time averaged 9.03 h of total care during a seven-day median treatment duration. These findings, taken together, demonstrate that canine parvovirus can be successfully treated in a sustainable manner within a shelter setting using a largely volunteer workforce.

Abstract
Objectives The purpose of this retrospective study was to assess outcomes of cats referred to a specialized adoption program for feline leukemia virus (FeLV)-positive cats. Methods Cats referred to an FeLV-specific adoption program between January 2018 and July 2019 at an animal shelter in Austin, TX, USA, were first identified based on their putative FeLV status as reported by the referring shelter, rescue group, veterinarian or individual. Each cat was re-screened for FeLV upon admission and subsequently deemed infected or uninfected. Data on cat source, admission date, outcome date, outcome type, signalment and comorbidities at the time of admission were extracted from the shelter database. Outcomes were recorded up to 15 December 2019. Results In total, 801 cats suspected to be infected with FeLV were referred to the FeLV adoption program. Of these, 149 (18.6%) were ultimately deemed uninfected, and infection was confirmed in 652 (81.4%) cats. Adoption was the most common outcome for FeLV-infected cats (n = 514 cats; 78.8%), followed by euthanasia or death in care (n = 109; 16.7%). Upper respiratory infection (URI) was the most common comorbidity in FeLV-infected cats (n = 106; 16.3%) at the time of admission, which was not significantly different than URI in the cats that were deemed not to be infected with FeLV (n = 29; 19.5%). Conclusions and relevance This study demonstrated high national demand for a lifesaving option for cats diagnosed with FeLV. FeLV infections could not be confirmed in approximately one in five cats referred to the FeLV adoption program, a reminder of the risk behind basing the fate of a cat on a single positive test result. The majority of cats referred to the FeLV program were adopted, demonstrating that programs centered on adopter education and post-adoption support can create lifesaving outcomes for most FeLV-infected cats, despite uncertainty regarding their long-term prognosis.

Abstract
BACKGROUND There have been few studies of sufficient size to address the relationship between glioma risk and the use of aspirin or NSAIDs, and results have been conflicting. The purpose of this study was to examine the associations between glioma and aspirin/NSAID use, and to aggregate these findings with prior published studies using meta-analysis. METHODS The Glioma International Case-Control Study (GICC) consists of 4,533 glioma cases and 4,171 controls recruited from 2010 to 2013. Interviews were conducted using a standardized questionnaire to obtain information on aspirin/NSAID use. We examined history of regular use for ≥6 months and duration-response. Restricted maximum likelihood meta-regression models were used to aggregate site-specific estimates, and to combine GICC estimates with previously published studies. RESULTS A history of daily aspirin use for ≥6 months was associated with a 38% lower glioma risk, compared with not having a history of daily use [adjusted meta-OR = 0.62; 95% confidence interval (CI), 0.54-0.70]. There was a significant duration-response trend (P = 1.67 × 10-17), with lower ORs for increasing duration of aspirin use. Duration-response trends were not observed for NSAID use. In the meta-analysis aggregating GICC data with five previous studies, there was a marginally significant association between use of aspirin and glioma (mOR = 0.84; 95% CI, 0.70-1.02), but no association for NSAID use. CONCLUSIONS Our study suggests that aspirin may be associated with a reduced risk of glioma. IMPACT These results imply that aspirin use may be associated with decreased glioma risk. Further research examining the association between aspirin use and glioma risk is warranted.

Abstract
Background Most multiple myeloma (MM) patients ultimately progress, with remission duration decreasing after first relapse. Recently, novel agents have been approved for the treatment of relapsed MM. There is a paucity of real-world data on these treatments. We sought to compare time to next treatment (TTNT) in MM patients in their second line of therapy (LOT2), treated with common proteasome inhibitor (PI)-based triplets. Methods Adult MM patients who received carfilzomib (K) between 1 November 2013 and 29 February 2016 at US Oncology Network (USON) clinics utilizing iKnowMed™ electronic health records (EHRs) were identified. Patients were included if they were ⩾18 years of age, not enrolled in clinical trials, had ⩾2 visits at a USON clinic and received LOT2 regimens consisting of: K+lenalidomide with steroid (KRd), bortezomib+lenalidomide with steroid (VRd), or bortezomib+cyclophosphamide with steroid (VCyd). TTNT was estimated from LOT2 initiation to LOT3 initiation using the Kaplan-Meier method, and hazard ratios (HRs) were estimated using Cox modeling. Results A total of 718 patients received a K-containing regimen sometime during their MM treatment (LOT1 to LOT5). Of these, 156 patients received: KRd (n = 112; 71.8%), VRd (n =27; 17.3%), or VCyd (n = 17; 10.9%). Baseline characteristics were similar between groups (mean age: 64.8 years; 58% male). Median TTNT was longest for KRd [25.3 months; 95% confidence interval (CI): 19.71-NR], versus VRd or VCyd (VRd median TTNT: 10.2 months, 95% CI: 4.24-12.71; VCyd: 6.5 months, 95% CI: 3.02-12.78; log-rank p < 0.0001). The adjusted HR for KRd was 0.19 (95% CI: 0.11-0.37), compared with VRd. Conclusions Considering the real-world nature of these data, the median TTNT observed with KRd was relatively consistent, with progression-free survival (PFS) for KRd observed in the phase III ASPIRE trial (median PFS: ITT population = 26.3 months; LOT2 = 29.6 months). Patients who received KRd at first relapse had significantly longer TTNT, compared with those on VRd or VCyd, confirming the value of KRd as an important treatment option for relapsed MM.

Abstract
OBJECTIVES The composition and structure of site-specific microbiota have been investigated as potential biomarkers for a variety of chronic inflammatory diseases and cancers. While many studies have focused on the changes in the airway microbiota using respiratory specimens from patients with various respiratory diseases, more research is needed to explore the microbial profiles within the distal lung parenchyma in smokers with lung cancer and/or emphysema. MATERIALS AND METHODS To describe and contrast lung tissue-associated microbial signatures in smokers with lung cancer and/or emphysema, we employed culture-independent pyrosequencing of 16S rRNA gene hypervariable V4 region and compositional analysis in non-malignant lung tissue samples obtained from 40 heavy smokers, including 10 emphysema-only, 11 lung cancer-only, and 19 with both lung cancer and emphysema. RESULTS AND CONCLUSION The emphysema-only group presented a lower bacterial community evenness defined by a significantly lower Shannon diversity index compared to the lung cancer patients with or without emphysema (P = 0.006). Furthermore, community compositions of lung cancer patients with or without emphysema were characterized by a significantly lower abundance of Proteobacteria (primary the genera Acinetobacter and Acidovorax) and higher prevalence of Firmicutes (Streptococcus) and Bacteroidetes (Prevotella), compared to emphysema-only patients. In conclusion, the lung microbial composition and communities structures of smokers with lung cancer are distinct from the emphysema-only patients. Although preliminary, our findings suggest that lung microbiome changes could be a biomarker of lung cancer that could eventually be used to help screening for the disease.

Abstract
BACKGROUND The purpose of this study was to evaluate the distribution of glioma-related seizures and seizure control at the time of tumor diagnosis with respect to tumor histologic subtypes, tumor treatment and patient characteristics, and to compare seizure history preceding tumor diagnosis (or study enrollment) between glioma patients and healthy controls. METHODS The Glioma International Case Control study (GICC) risk factor questionnaire collected information on demographics, past medical/medication history, and occupational history. Cases from eight centers were also asked detailed questions on seizures in relation to glioma diagnosis; cases (n = 4533) and controls (n = 4171) were also asked about seizures less than 2 years from diagnosis and previous seizure history more than 2 years prior to tumor diagnosis, including childhood seizures. RESULTS Low-grade gliomas (LGGs), particularly oligodendrogliomas/oligoastrocytomas, had the highest proportion of glioma-related seizures. Patients with low-grade astrocytoma demonstrated the most medically refractory seizures. A total of 83% of patients were using only one antiepileptic drug (AED), which was levetiracetam in 71% of cases. Gross total resection was strongly associated with reduced seizure frequency (p < 0.009). No significant difference was found between glioma cases and controls in terms of seizure occurring more than 2 years before diagnosis or during childhood. CONCLUSIONS Our study showed that glioma-related seizures were most common in low-grade gliomas. Gross total resection was associated with lower seizure frequency. Additionally, having a history of childhood seizures is not a risk factor ***for developing glioma-related seizures or glioma.

Abstract
Primary brain tumors are predominantly malignant gliomas. Grade IV astrocytomas (glioblastomas, GBM) are among the most deadly of all tumors; most patients will succumb to their disease within 2 years of diagnosis despite standard of care. The grim outlook for brain tumor patients indicates that novel precision therapeutic targets must be identified. Our hypothesis is that the cancer proteomes of glioma tumors may contain protein variants that are linked to the aggressive pathology of the disease. To this end, we devised a novel workflow that combined variant proteomics with molecular epidemiological mining of public cancer data sets to identify 10 previously unrecognized variants linked to the risk of death in low grade glioma or GBM. We hypothesize that a subset of the protein variants may be successfully developed in the future as novel targets for malignant gliomas.

Abstract
OBJECTIVE Geographic and racial disparities may contribute to variation in the incidence and outcomes of HIV-associated cancers in the United States. METHOD Using the Surveillance, Epidemiology, and End Results (SEER) database, we analyzed Kaposi sarcoma (KS) incidence and survival by race and geographic region during the combined antiretroviral therapy era. Reported cases of KS in men from 2000 to 2013 were obtained from 17 SEER cancer registries. Overall and age-standardized KS incidence rates were calculated and stratified by race and geographic region. We evaluated incidence trends using joinpoint analyses and calculated adjusted hazard ratios (aHR) for overall and KS-specific mortality using multivariable Cox proportional hazards models. RESULTS Of 4,455 KS cases identified in men younger than 55 years (median age 40 years), the annual percent change (APC) for KS incidence significantly decreased for white men between 2001 and 2013 (APC -4.52, p = 0.02). The APC for AA men demonstrated a non-significant decrease from 2000-2013 (APC -1.84, p = 0.09). Among AA men in the South, however, APC has significantly increased between 2000 and 2013 (+3.0, p = 0.03). In addition, compared with white men diagnosed with KS during the same time period, AA men were also more likely to die from all causes and KS cancer-specific causes (aHR 1.52, 95% CI 1.34-1.72, aHR 1.49, 95% CI 1.30-1.72 respectively). CONCLUSION Although overall KS incidence has decreased in the U.S., geographic and racial disparities in KS incidence and survival exist.

Abstract
Abstract
BACKGROUND: Gliomas are highly infiltrated by immune cells including microglia, macrophages, and myeloid-derived suppressor cells (collectively, glioma-associated myeloid cells). These cells have been shown to be induced by the tumor to be immune-suppressive and tumor-supportive, and are a negative prognosticator for survival in mouse models. Here, we examine whether inherited variants in genes important to the function of glioma-associated myeloid cells are associated with survival following low-grade glioma diagnosis.
METHODS: Subjects for this study were 484 patients with WHO grade II or grade III glioma treated at The University of Texas MD Anderson Cancer Center in Houston, Texas between 1992 and 2008 and followed up for survival through August, 2016. We selected 100 genes for analysis including transcription factors, cytokines and chemokines, receptors, enzymes, and other genes central to the function of glioma-associated myeloid cells. Genotyping was originally performed using the Illumina Human 610-Quad Bead Chip platform and 2,040 tagging SNPs as determined by Haploview Tagger software were selected for analysis with minor allele frequency (AF) ≥ 1%. Associations between selected SNPs and survival were evaluated by Cox regression analysis under an additive allelic model adjusting for age, sex, extent of surgery (biopsy only/partial resection/gross total resection), radiotherapy (yes/no), and chemotherapy (yes/no). Models were examined to ensure that proportional hazards assumptions were not violated.
RESULTS: Median survival among low-grade glioma patients was 6.7 years. Age at diagnosis, extent of surgery, and having received radiotherapy or chemotherapy were each significantly associated with survival. Five SNPs were associated with survival at a significance level of p<0.001, and two remained significantly associated with low-grade glioma survival after adjustment for multiple comparisons (FDR-adjusted p-value (q)<0.10). These results indicated inferior survival for carriers of the C allele (AF=1.4%) at rs147960238 in CD163 (HR=5.47, 95% CI: 2.49-11.99, p=2.23x10-5, q=0.046) and for carriers of the G allele (AF=3.8%) at rs17138945 in MET (HR=2.27, 95% CI: 1.52-3.38, p=5.61x10-5, q=0.057). These SNPs are located in the 10th and 2nd introns of CD163 and MET, respectively.
CONCLUSIONS: Here we provide preliminary evidence of an association between polymorphisms in two genes related to glioma-associated myeloid cell function and low-grade glioma survival. CD163 is a receptor that is highly expressed on macrophages and may play a role in macrophage-mediated anti-inflammatory responses, while MET is a receptor tyrosine kinase and well-studied proto-oncogene that is also involved in the expansion of myeloid-derived suppressor cell populations. Further investigation of these associations is warranted, and validation of these findings is planned in an independent population.

Abstract
e19517 Background: Carfilzomib (K) is indicated for treatment of relapsed or refractory multiple myeloma (MM). We studied the characteristics of patients receiving K in the US Oncology Network’s (USON) EHR database. Methods: Patients ≥18 years who received a K-containing regimen between 11/01/2013-02/29/2016, were not in a clinical trial, and had ≥2 visits at a USON clinic were eligible. Baseline characteristics were compared between patients who received a K-based doublet, triplet or other regimen (monotherapy or >3 treatments). Results: Of the 718 patients who received a K-based regimen during the study period, 219 (30.5%) had doublet regimens, 287 (40.0%) received triplet regimens and 212 (29.5%) received other regimens; 494 (68.8%) received regimens with ≥3 therapies. Mean age was 69.7 and 64.7 years among patients on doublets and triplets, respectively. A higher proportion of female patients received doublets (53.0%) (Table). There were no differences in ISS stage or number of comorbidities across patients receiving doublets, triplets, or other regimens. Conclusions: In this real-world analysis of K-regimens, a majority of patients received triplet regimens. Older patients received doublet regimens more frequently. The influence of regimen on outcomes controlling for patient characteristics and prior treatments among MM patients receiving K-based regimens should be studied. [Table: see text]

Abstract
e19513 Background: The purpose of this retrospective cohort study was to describe the treatment regimens received by adult multiple myeloma (MM) patients who were exposed to carfilzomib (K) in the US Oncology Network (USON). Methods: Eligible patients received K-based regimens for MM at least once between 11/01/2013 and 02/29/2016, were ≥18 years old, were not in a clinical trial, and had at least 2 visits at a USON clinic. Data on systemic therapies, lines of therapy (LOT), clinic visits and treatment administration dates were abstracted from the electronic health records (EHR). Treatment sequencing logic was used to identify progression by LOT. Sequencing rules were based on regimens, duration, and administration dates. Treatment regimens utilized at any time during the study period were analyzed by LOT. Results: 718 MM patients received a K-containing regimen at least once over the course of treatment. The frequency distribution of regimens for K-exposed patients by LOT (2 to 5) are provided (see Table). Among these patients, K-based regimens comprised 66.6% of LOT2 regimens, 55.3% of LOT3 regimens, and 45.9% of regimens used beyond LOT3. K+ lenalidomide + dex (KRd) was the most common K-containing regimen used in LOT2 (24.7%). K-triplets containing an immunomodulatory agent were most frequent in LOT 2 and K-doublets (Kd) were most frequent in LOT 3. Conclusions: In our study, K-based regimens were used across LOTs 2 to 5 with highest frequency observed in LOT2. K-triplets with immunomodulatory drugs were more common in earlier LOTs.

Abstract
Abstract
Background: Numerous epidemiologic studies have examined the association between aspirin (ASA), non-steroid anti-inflammatory drugs (NSAIDs) and the development of glioma, but the results have been inconsistent. The goal of this study was to evaluate the relationship between the intake of these drugs and glioma risk in a large, international case-control study.
Methods: Between 2010 and 2015, the Glioma International Case-Control Study (GICC) recruited newly diagnosed glioma cases and matched controls in 14 different sites across five countries. Each subject was interviewed using a standardized questionnaire to obtain NSAIDs and ASA use. We examined the associations between ever use (at least > 6 months), duration of drug use and glioma histology. Ever use data on 4533 glioma cases and 4171 controls was combined using maximum likelihood estimation/restricted maximum likelihood meta-analysis methods. Furthermore, based on a priori hypotheses, we performed subgroup analyses based on gender and glioma histological grades.
Results: Use of ASA for > 6 months was associated with a 33% lower glioma risk compared to those who never took it (adjusted Meta-OR 0.67, 95% CI 0.54-0.83). Duration of intake showed a significant trend test (p < 0.0001), with ORs became lower for increasing number of years of ASA use. In subgroup analyses, intake of ASA was significantly associated with glioma risk in both men and women (adjusted Meta-OR = 0.65, 95% CI 0.51-0.84 for men; adjusted Meta-OR = 0.74, 95% CI 0.58-0.93 for women). ASA intake was protective for grade IV glioma (glioblastoma) and grade II/III glioma (adjusted meta-OR 0.63, 95% CI 0.5-0.8 for glioblastoma; adjusted meta-OR 0.67, 95% CI 0.50 - 0.89 for grade II/III glioma). For NSAIDs intake, ever use > 6 months was not associated with glioma risk (adjusted meta-OR 0.87, 95% CI 0.71-1.07). However, NSAIDs use was protective for women (adjusted meta-OR 0.72, 95% CI 0.55-0.93) in subgroup analyses but not for men (adjusted meta-OR 1.03; 95% CI 0.86-1.23). The interaction between gender, NSAIDs and glioma risk was significant (p-value 0.0076).. Sensitivity analyses excluding those who took ASA or NSAIDs within the past 12 months for headache, and the removal of proxy respondents did not change our results.
Conclusion: ASA was associated with a significant protective effect for glioma, but NSAIDs were only associated with reduced glioma risk in women. Given the possibility of recall bias in case-control studies of brain tumors, we may verify dosage and duration of drug intake in those countries with electronic pharmacy records within the GICC.

Abstract
Varicella zoster virus (VZV) is a neurotropic α‐herpesvirus that causes chickenpox and establishes life‐long latency in the cranial nerve and dorsal root ganglia of the host. To date, VZV is the only virus consistently reported to have an inverse association with glioma. The Glioma International Case‐Control Study (GICC) is a large, multisite consortium with data on 4533 cases and 4171 controls collected across five countries. Here, we utilized the GICC data to confirm the previously reported associations between history of chickenpox and glioma risk in one of the largest studies to date on this topic. Using two‐stage random‐effects restricted maximum likelihood modeling, we found that a positive history of chickenpox was associated with a 21% lower glioma risk, adjusting for age and sex (95% confidence intervals (CI): 0.65–0.96). Furthermore, the protective effect of chickenpox was stronger for high‐grade gliomas. Our study provides additional evidence that the observed protective effect of chickenpox against glioma is unlikely to be coincidental. Future studies, including meta‐analyses of the literature and investigations of the potential biological mechanism, are warranted.

Abstract
BACKGROUND Several previous studies have found inverse associations between glioma susceptibility and a history of allergies or other atopic conditions. Some evidence indicates that respiratory allergies are likely to be particularly relevant with regard to glioma risk. Using data from the Glioma International Case-Control Study (GICC), we examined the effects of respiratory allergies and other atopic conditions on glioma risk. METHODS The GICC contains detailed information on history of atopic conditions for 4,533 cases and 4,171 controls, recruited from 14 study sites across five countries. Using two-stage random-effects restricted maximum likelihood modeling to calculate meta-analysis ORs, we examined the associations between glioma and allergy status, respiratory allergy status, asthma, and eczema. RESULTS Having a history of respiratory allergies was associated with an approximately 30% lower glioma risk, compared with not having respiratory allergies (mOR, 0.72; 95% confidence interval, 0.58-0.90). This association was similar when restricting to high-grade glioma cases. Asthma and eczema were also significantly protective against glioma. CONCLUSION A substantial amount of data on the inverse association between atopic conditions and glioma has accumulated, and findings from the GICC study further strengthen the existing evidence that the relationship between atopy and glioma is unlikely to be coincidental. IMPACT As the literature approaches a consensus on the impact of allergies in glioma risk, future research can begin to shift focus to what the underlying biologic mechanism behind this association may be, which could, in turn, yield new opportunities for immunotherapy or cancer prevention.

Abstract
Decades of research have established only a few etiological factors for glioma, which is a rare and highly fatal brain cancer. Common methodological challenges among glioma studies include small sample sizes, heterogeneity of tumor subtypes, and retrospective exposure assessment. Here, we briefly describe the Glioma International Case-Control (GICC) Study (recruitment, 2010-2013), a study being conducted by the Genetic Epidemiology of Glioma International Consortium that integrates data from multiple data collection sites, uses a common protocol and questionnaire, and includes biospecimen collection. To our knowledge, the GICC Study is the largest glioma study to date that includes collection of blood samples, which will allow for genetic analysis and interrogation of gene-environment interactions.

Abstract
Protease inhibitors (PIs) have been shown to have anti-tumor activity in addition to their antiretroviral properties. We sought to assess the association between PI use and the incidence of squamous cell carcinoma of the anus (SCCA) in HIV-infected individuals. We performed a retrospective cohort study among male US veterans diagnosed with HIV who were diagnosed between 1985 and 2010, using the Veterans Affairs HIV Clinical Case Registry (CCR). We calculated hazards ratios associated with PI use (both as percent time on PI and as 12-month intervals of PI use), utilizing time-dependent Cox models. We adjusted for risk factors, including age, race, year of enrolment into CCR, recent and nadir CD4, and percent time undetectable HIV viral load. A total of 28, 886 HIV-infected men met inclusion criteria. Of these, 373 were newly diagnosed with SCCA during the study period. In multivariate analysis, increasing percent time on PIs was associated with an increased risk of SCCA (aHR 1.07; 95% CI = 1.03–1.10 per 10% increase in time on PI). Poor immunologic recovery and virologic control, a history of condylomata acuminata, and CCR enrolment in the late combined antiretroviral therapy era were also associated with increased SCCA risk. Increasing percent time on a PI-based combined antiretroviral therapy regimen may be associated with an increased risk of developing SCCA in HIV-infected male US veterans. Future studies, better accounting for HIV control and treatment compliance, are necessary to further clarify this association.

Abstract
Abstract
Background: The composition and structure of site-specific microbiota have recently been described as a biomarker associated with a variety of high impact diseases including cancer. This study sought to identify lung microbial signatures in smokers with lung cancer (LC) and/or chronic obstructive pulmonary disease (COPD).
Material and Methods: We employed 16S rRNA gene compositional analysis to compare the microbiota in Optimal Cutting Temperature (OCT) embedded biopsies of lung-tissue from 30 smokers, including 10 patients with LC only, 10 patients with COPD only, and 10 patients with both LC and COPD, selected from a longitudinal study of COPD exacerbation conducted in Houston, Texas, during 2005 to 2012.
Results: Microbial signatures calculated based on the 16S rRNA gene data showed that patients with COPD only presented a very distinct microbial structure defined by a significantly lower Shannon Diversity Index compared to patients with LC only (P = 0.04), and patients with both LC and COPD (P = 0.003), suggesting lower bacterial richness and evenness. Furthermore, biopsies from patients with COPD only were characterized by an increased prevalence of Acinetobacter (P < 0.0001) and Acidovorax (P < 0.0001), and a lower prevalence of Bifidobacterium, Streptococcus, and Ruminococcus species compared to patients with LC only and those with both LC and COPD. However, patients with both COPD and LC were indistinguishable from those with LC only.
Conclusions: This study is the first and largest to examine the composition of the lung microbiome in smokers with LC and/or COPD. Specific bacterial signatures were identified in patients with LC only and those with both COPD and LC demonstrating that the lung microbiome can be used as a biomarker for the two diseases. Altogether, we observed altered lung microbiota of COPD and LC, but whether this is involved in disease causation or is a consequence of host selection remains unclear.

Abstract
Glioma is a rare, but highly fatal, cancer that accounts for the majority of malignant primary brain tumors. Inherited predisposition to glioma has been consistently observed within non-syndromic families. Our previous studies, which involved non-parametric and parametric linkage analyses, both yielded significant linkage peaks on chromosome 17q. Here, we use data from next generation and Sanger sequencing to identify familial glioma candidate genes and variants on chromosome 17q for further investigation. We applied a filtering schema to narrow the original list of 4830 annotated variants down to 21 very rare (<0.1% frequency), non-synonymous variants. Our findings implicate the MYO19 and KIF18B genes and rare variants in SPAG9 and RUNDC1 as candidates worthy of further investigation. Burden testing and functional studies are planned.

Abstract
Abstract
Introduction: Compared to non-Hispanic whites, Hispanics in the U.S. are significantly more likely to be diagnosed with late-stage colorectal cancer (CRC) and have a higher CRC-specific mortality hazard. While the low CRC screening rates among Hispanics (29%) are known to be lowest among foreign-born individuals (22%), few studies have examined CRC disparities by nativity. Here we examine differences in late-stage CRC diagnosis and survival among U.S.- and foreign-born Hispanics.
Methods: We used data from the Surveillance, Epidemiology, and End Results (SEER) program. Cases were Hispanic men and women diagnosed with primary invasive CRC between 1988 and 2008. Nativity was based on place of birth and was categorized as U.S.- versus foreign-born. Missing nativity values were imputed using multiple imputation by logistic regression, a strategy with high sensitivity (91%) and specificity (90%) for detecting foreign-born status. Distant and regional tumors were classified as late-stage; local tumors were classified as early-stage. Multivariable logistic regression was used to assess the association between late-stage diagnosis and nativity after adjusting for demographic characteristics (age at diagnosis and gender) and anatomic subsite (proximal, distal, rectum, or other). Multivariable Cox regression was used to assess the association between CRC-specific survival and nativity after adjusting for demographic characteristics, tumor characteristics (stage at diagnosis and anatomic subsite), and receipt of cancer-directed therapy (surgery and radiation).
Results: Fifty eight percent of cases of invasive CRC among Hispanics were diagnosed at a late stage and 63% of cases were among foreign-born individuals. Foreign-born Hispanics were significantly more likely than U.S.-born Hispanics to have a late-stage diagnosis after adjusting for demographic characteristics (adjusted odds ratio=1.08, p<0.001). However, the demographics-adjusted mortality hazard was similar among foreign- and U.S.-born Hispanics (adjusted hazard ratio [AHR]=0.99, p-value=0.790). After adjusting for tumor characteristics, foreign-born Hispanics had improved survival compared to their U.S.-born counterparts (AHR=0.94, p=0.005). Their survival advantage remained significant after adjusting for both tumor characteristics and cancer-directed therapy (AHR=0.92, p<0.001).
Conclusions: The increased prevalence of late-stage diagnosis among foreign-born Hispanics is likely a reflection of their reduced screening rates relative to Hispanics born in the U.S. However, the increased risk of late-stage diagnosis did not result in an increased mortality hazard among foreign-born Hispanics. In fact, survival was better among foreign- versus U.S.-born Hispanics after adjusting for stage at diagnosis and receipt of cancer-directed therapy. Similar patterns have been found for cervix and overall cancer survival and may be attributed to changes in risk profiles associated with acculturation (e.g., higher rates of smoking, obesity, alcohol consumption, and poor nutrition). Additionally, U.S.-born Hispanics have a higher prevalence of chronic diseases (e.g., diabetes, obesity, heart disease) that may negatively affect cancer survival. Our results suggest that the overlap between race/ethnicity and nativity status should not be overlooked in cancer health disparities research.

Abstract
Abstract
Purpose: Human papillomavirus (HPV), the causative agent for anogenital and certain head and neck cancers, has been detected in lung tumors, but its role as an etiologic agent for lung cancer remains controversial. The lung is often subjected to exogenous inflammatory insults, and patients with chronic lung inflammation have an increased risk for cancer. In addition to the genomic instability that can be caused by HPV oncoproteins, the immunomodulatory impacts of HPV infection may foster a pro-inflammatory state that increases lung cancer risk. We sought to identify such immunomodulatory effects by examining the differences in lymphocyte and cytokine/chemokine profiles between lung cancer cases and HPV-vaccinated healthy controls.
Methods: Peripheral blood mononuclear cells were isolated from 22 newly diagnosed lung cancer cases and 11 healthy controls who had prior exposure to HPV antigens (immunized with Gardasil). Cells were enumerated via a hemacytometer, and were exposed to media alone or to 3 doses of Gardasil for 20 hours as an HPV challenge. Interleukin (IL-) 4, IFN-γ, and IL-17A secreting cells were then quantified using enzyme linked immunocell spot (ELISpot) analysis. Individuals were categorized as HPV-responsive if the HPV challenge resulted in an increase in at least 2 types of secreting cells, compared to media-exposed cells. The Milliplex human cytokine detection kit was used to assess circulating levels of 38 key cytokines in the plasma of cases and controls. Cytokine levels among HPV-responsive and HPV-non-responsive cases were compared. Survival analysis was also conducted.
Results: All 11 HPV-vaccinated controls demonstrated an increase in cells secreting IFN-γ and IL-4. Of the 22 cases, 13 (59%) were classified as HPV-responsive, with 2 cases displaying an increase in IFN-γ and IL-4 secreting cells upon HPV challenge. Levels of TGF-α, IL-10, IL-3, IL-5, and IL-7 were significantly higher among HPV-responsive compared to non-responsive cases. Significant survival differences were also observed by HPV-responsiveness and cytokine levels.
Conclusions: HPV clearly has substantial effects on the host's systemic immune response. Our study may explain whether and how the pathogenic process differs between HPV-infected and -uninfected lung tumors.

Abstract
The life expectancy for HIV-positive individuals has improved over time due to increasing access to highly active antiretroviral therapy (HAART). Yet, as the HIV-positive population ages, their risk of developing cancers also increases. Studies of Kaposi's sarcoma (KS) among elderly HIV-infected persons are quite limited. We examined the age patterns of KS incidence and an association between age and KS risk in a US cohort of 3458 HIV-infected men, the Multicenter AIDS Cohort Study (MACS). Poisson distribution was used to calculate incidence rates and respective 95% confidence intervals (95% CIs). Cox proportional hazards regression was performed to examine the association between age and KS risk. There were 534 incident KS cases with a total follow-up time of 25,134 person-years. The overall KS incidence rate was 2.13 per 100 person-years (95% CI: 1.95–2.32) (Non-HAART users-ever: 5.57 per 100 person-years [95% CI: 5.09–6.10]; HAART users-ever: 0.39 per 100 person-years [95% CI: 0.31–0.51]). Overall, KS frequency and incidence declined with age, even in the oldest age group (ptrend < 0.0001). However, among non-HAART users-ever, the oldest age group had the highest incidence rate ratio compared to younger individuals [15.01, 95% CI: 6.12–44.22]). While the incidence of KS decreased with age, older HIV-infected persons who do not receive HAART are still at increased risk of KS. As KS remains an important malignancy among HIV-infected persons, earlier HIV diagnoses and HAART initiation, particularly in older HIV-infected persons is warranted.

Abstract
BACKGROUND Although birthplace data are routinely collected in the participating Surveillance, Epidemiology, and End Results (SEER) registries, such data are missing in a nonrandom manner for a large percentage of cases. This hinders analysis of nativity-related cancer disparities. In the current study, the authors evaluated multiple imputation of nativity status among Hispanic patients diagnosed with cervical, prostate, and colorectal cancer and demonstrated the effect of multiple imputation on apparent nativity disparities in survival. METHODS Multiple imputation by logistic regression was used to generate nativity values (US-born vs foreign-born) using a priori-defined variables. The accuracy of the method was evaluated among a subset of cases. Kaplan-Meier curves were used to illustrate the effect of imputation by comparing survival among US-born and foreign-born Hispanics, with and without imputation of nativity. RESULTS Birthplace was missing for 31%, 49%, and 39%, respectively, of cases of cervical, prostate, and colorectal cancer. The sensitivity of the imputation strategy for detecting foreign-born status was ≥90% and the specificity was ≥86%. The agreement between the true and imputed values was ≥0.80 and the misclassification error was ≤10%. Kaplan-Meier survival curves indicated different associations between nativity and survival when nativity was imputed versus when cases with missing birthplace were omitted from the analysis. CONCLUSIONS Multiple imputation using variables available in the SEER data file can be used to accurately detect foreign-born status. This simple strategy may help researchers to disaggregate analyses by nativity and uncover important nativity disparities in regard to cancer diagnosis, treatment, and survival.

Abstract
The Papanicolaou test (or Pap test) has long been used as a screening tool to detect cervical precancerous/cancerous lesions. However, studies on the use of this test to predict both the presence and change in size of genital warts are limited. We examined whether cervical Papanicolaou test results are associated with the size of the largest anal wart over time in HIV-infected women in an on-going cohort study in the US. A sample of 976 HIV-infected women included in a public dataset obtained from the Women’s Interagency HIV Study (WIHS) was selected for analysis. A linear mixed model was performed to determine the relationship between the size of anal warts and cervical Pap test results. About 32% of participants had abnormal cervical Pap test results at baseline. In the adjusted model, a woman with a result of Atypia Squamous Cell Undetermined Significance/Low-grade Squamous Intraepithelial Lesion (ASCUS/LSIL) had an anal wart, on average, 12.81 mm2 larger than a woman with normal cervical cytology. The growth rate of the largest anal wart after each visit in a woman with ASCUS/LSIL was 1.56 mm2 slower than that of a woman with normal cervical results. However, they were not significant (P = 0.54 and P = 0.82, respectively). This is the first study to examine the relationship between cervical Pap test results and anal wart development in HIV-infected women. Even though no association between the size of anal wart and cervical Pap test results was found, a screening program using anal cytology testing in HIV-infected women should be considered. Further studies in cost-effectiveness and efficacy of an anal cytology test screening program are warranted.

Abstract
Background Among men in the U.S., prostate cancer is the most common cancer and the second leading cause of cancer death. Despite its prevalence, there are few established risk factors for prostate cancer. Some studies have found that intake of certain foods/nutrients may be associated with prostate cancer risk, but few have accounted for how intake and metabolic factors may interact to influence bioavailable nutrient levels and subsequent disease risk. Presentation of the hypothesis The composition of the gastrointestinal (GI) microbiome may influence metabolism of dietary compounds and nutrients (e.g., plant phenols, calcium, choline) that may be relevant to prostate cancer risk. We, therefore, propose the hypothesis that GI microbiota may have a markedly different composition among individuals with higher prostate cancer risk. These individuals could have microbial profiles that are conducive to intestinal inflammation and/or are less favorable for the metabolism and uptake of chemopreventive agents. Testing the hypothesis Because very little preliminary data exist on this potential association, a case–control study may provide valuable information on this topic. Such a study could evaluate whether the GI microbial profile is markedly different between three groups of individuals: healthy men, those with latent prostate cancer, and those with invasive prostate cancer. Any findings could then be validated in a larger study, designed to collect a series of specimens over time. Implications of the hypothesis Given the plethora of information emerging from the Human Microbiome Project, this is an opportune time to explore associations between the microbiome and complex human diseases. Identification of profiles that alter the host’s risk for disease may clarify inconsistencies in the literature on dietary factors and cancer risk, and could provide valuable targets for novel cancer prevention strategies.

Abstract
PURPOSE While cervical cancer screening and risk behaviors have been found to vary among US- and foreign-born Hispanic women, many cancer epidemiology studies have conceptualized Hispanics as a homogenous group. Here, we examine differences in cervical cancer stage at diagnosis and survival among Hispanic women by nativity. METHODS We use data from the Surveillance, Epidemiology, and End Results program, 1998-2008. Nativity was based on place of birth and was categorized as US versus foreign born. Distant and regional tumors were classified as late stage, while local tumors were classified as early stage. RESULTS Forty-seven percent of cases of invasive cervical cancer among Hispanics were diagnosed at a late stage, and over half of invasive cervical cancer cases were among foreign-born women. Foreign-born Hispanic women were significantly more likely than US-born Hispanics to have late-stage diagnosis, after adjusting for age at diagnosis and tumor histology (adjusted odds ration = 1.09, p value = 0.003). There was heterogeneity in the association between nativity and survival by stage at diagnosis. Among cases with early-stage diagnosis, survival was poorer among foreign-born versus US-born Hispanics after adjusting for age at diagnosis, histology, and cancer-directed therapy [adjusted hazard ratios (HR) = 1.31, p value = 0.030]. However, among cases with late-stage diagnosis, survival was better among foreign-born Hispanics (adjusted HR = 0.81, p value < 0.001). CONCLUSIONS We hypothesize that nativity differences in survival may be indicative of diverse risk, screening, and treatment profiles. Given such differences, it may be inappropriate to aggregate Hispanics as a single group for cervical cancer research.

Abstract
Wilms' tumors (WT) constitute approximately 6-14% of all childhood cancers and about 95% of all pediatric renal malignancies. While prognostic factors for this malignancy are relatively well-defined, few studies have specifically examined the role of Hispanic ethnicity in pediatric WT survival. The purpose of this study was to compare WT survival among non-Hispanic white (NHW), non-Hispanic black (NHB), and Hispanic cases using data from the Surveillance, Epidemiology, and End Results (SEER) program. WT cases (ICD-O-3 histological code 8960) under age 20 were isolated from a recent subset of the SEER dataset (1990-2009). Demographics and tumor characteristics were compared by race/ethnicity, and 5- and 10-year survival probabilities were calculated. Multivariable Cox proportional hazards regression was used to assess the effects of race/ethnicity on WT survival, adjusting for relevant covariates. Hispanic ethnicity was significantly associated with WT-specific mortality hazard, controlling for age, sex, diagnosis/treatment era, laterality, SEER stage, cancer-directed surgery, and radiation therapy (HR: 1.52, 95% CI: 1.02-2.25). The results of this study suggest that Hispanic pediatric WT cases may have a higher risk of WT-related death, compared to NHW cases. Additional research on racial/ethnic disparities in WT survival is warranted.

Abstract
Cervical cancer (CxCa) is the second most common cancer among women globally. Human papillomavirus (HPV) infection is thought to be a necessary, but not sufficient, causal factor in CxCa development. Why some women are able to clear HPV infection with no adverse effects, whereas others develop cancer, remains unclear. HHV-6 has demonstrated transformative abilities and has been shown to be present in the genital tract. However, based on the current evidence, we cannot conclude that HHV-6 is a co-factor in HPV-associated carcinogenesis. Nonetheless, future research is warranted because of several crucial gaps in the literature.

Abstract
Background: Although the independent effects of smoking status and HAART are reported as lower risks against KS, their combined effects have not been explored. We examined whether there is an interaction between smoking status and HAART use on the risk of KS development in an on-going US cohort of HIV-infected men. Methods: Cox proportional hazards regression was used to analyse a total sample of 2736 participants of the Multicenter AIDS Cohort Study (MACS). Results: We identified 530 incident KS cases with a total follow-up time of 26 594 person-years (incidence rate: 2.00 out of 100 person-years). Current smoking status and HAART use were independently associated with a lower risk of KS development (hazard ratio – HR=0.56, 95% CI: 0.35–0.90, P=0.02 and HR=0.27, 95% CI: 0.16–0.48, P<0.0001, respectively). There was no evidence of multiplicative interaction between current smoking status and HAART use on KS risk (HR=2.14, 95% CI: 0.97–4.73, Pinteraction=0.06). Lower effect of smoking was only present among those not on HAART (HR=0.57, 95% CI: 0.35–0.92, P=0.02). Conclusion: The inverse association of cigarette smoking on KS risk may be limited to those not on HAART. The biological mechanism of smoking in KS carcinogenesis should be elucidated.

Abstract
The role of human cytomegalovirus (HCMV) in glioma development and progression remains controversial. The purpose of our study was to assess the potential associations between anti-HCMV antibodies (immunoglobulin G [IgG] and immunoglobulin M [IgM]) and glioma risk and prognosis using data from the Harris County Case–Control Study. Multivariable logistic regression models were utilized to estimate odds ratios and 95% confidence intervals (CI) for the associations between glioma status and antibody levels among glioma cases (n = 362) and cancer-free controls (n = 462). Hazard ratios and 95% CIs were calculated using Cox proportional hazards regression, adjusting for age, race, and sex, to determine if antibody levels were associated with survival over time among cases. Among IgG-positive participants, increasing anti-HCMV IgG levels were associated with decreasing glioma risk (P for trend = 0.0008), and those with the lowest level of anti-HCMV IgG (<10 U/mL) had the highest glioma risk, controlling for age, sex, and race/ethnicity (OR: 2.51, 95% CI: 1.42–4.43). Antibody levels were not associated with survival among glioma cases. Our study contributes new evidence toward the potential importance of the direct and indirect effects of HCMV infection in gliomagenesis.
