Traditional risk factors for CVEs were similar between HPV\positive and \negative patients. Over a median follow\up of 3.4?years, there were 18 ischemic strokes and 5 transient ischemic attacks (event rate of 1 1.8% per year). The annual event rate was higher in the HPV\positive patients compared with the HPV\negative patients (2.6% versus 0.9%, test for continuous variables, the Pearson 2 test for categorical variables, and the Wilcoxon rank sum test for ordinal variables. There were no missing covariates. Annualized event rates as a function of tumor HPV status were calculated, and KaplanCMeier event curves for CVEs were generated; time\course comparisons were performed by log\rank tests. We used Cox regression models to examine associations between the independent variables and the development of CVEs. Covariates included in the model were variables significant on univariate analysis as well as known predictors and confounders of CVEs.3, 20 Hazard ratios (HRs) for the association of HPV status with events were estimated using Cox proportional hazards. Time of follow\up was calculated from the start of RT, and censoring criteria included death, first stroke or TIA, or last documented visit for those without events or death. For all analyses, a 2\tailed value of 0.05 was considered significant. In addition, we performed competing risk analyses using death as the competing risk, given the expected difference in survival based on HPV tumor status, to further assess the impact of HPV status on cerebrovascular outcomes. From these analyses, an HR for CVE risk was obtained, adjusting for age, male sex, race, baseline lipids, blood pressure, Vigabatrin history of diabetes mellitus, smoking, and use of antihypertensive medications. Those participants with HPV testing performed were more likely to be nonsmokers, to be male, to have oropharyngeal cancer, and to have received platinum\based or taxol chemotherapy. Inverse probability weighting was used to account for the nonrandomness of missing HPV genotype status. Vigabatrin Statistical tests were performed using STATA version 14.1 (StataCorp). Results The final cohort included 326 patients treated with neck RT who were tested for HPV (Figure?1). The mean age of the entire cohort at the time of RT was 5912?years (range: 20C83?years), and 75% were male. The characteristics of the study population by HPV status are summarized in Table?1. Overall, 191 (59%) were tumor HPV positive. In addition, 89% of all included participants were treated with chemotherapy plus RT, 53% were comanaged with surgery, and 3% were treated with RT alone. Patients with HPV infection were more likely to be male and to have oropharyngeal cancer and less likely to have laryngeal carcinoma as their cancer type. There was no difference in the prevalence of baseline coronary or cerebrovascular disease or of traditional cardiovascular risk factors among groups with and without HPV.

Exportin 7 is primarily expressed in testis, thyroid and bone marrow, but is alsoexpressed in lung, liver and small intestine. Exportin 7 translocates proteins and large RNAsthrough the nuclear pore complex (NPC) and is localized to the cytoplasm and nucleus. Exportin 7has two types of receptors, designated importins and exportins, both of which recognize proteinsthat contain nuclear localization signals (NLSs) and are targeted for transport either in or out of thenucleus via the NPC. Additionally, the nucleocytoplasmic RanGTP gradient regulates Exportin 7distribution, and enables Exportin 7 to bind and release proteins and large RNAs before and aftertheir transportation. Exportin 7 is thought to play a role in erythroid differentiation and may alsointeract with cancer-associated proteins, suggesting a role for Exportin 7 in tumorigenesis CVE, age4.41 (1.5C13.1)0.008HPV status, prior CVE, age, male sex4.33 (1.4C13.1)0.009HPV status, prior CVE, age, male sex, neck dissection, radiation dose, oropharyngeal cancer, laryngeal cancer5.36 (1.7C16.7)0.004 Open in a separate window CI indicates confidence interval; CVE, cerebrovascular event; HPV, human papillomavirus; HR, hazard ratio.
