Haga T, Efird JT, Tugizov S, Palefsky JM. Increased TNF-alpha and sTNFR2 levels are associated with high-grade anal squamous intraepithelial lesions in HIV-positive patients with low CD4 level. PAPILLOMAVIRUS RESEARCH (AMSTERDAM, NETHERLANDS) 2017; 3:1-6. [PMID: 28720441 PMCID: PMC5883208 DOI: 10.1016/j.pvr.2016.11.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/20/2016] [Revised: 10/17/2016] [Accepted: 11/18/2016] [Indexed: 01/28/2023]
Abstract
Compared with HIV-negative individuals, HIV-positive individuals have a higher prevalence of anogenital human papillomavirus (HPV) infection, the causative agent of anogenital cancer. TNF-alpha is a major proinflammatory cytokine. sTNFR2 is the soluble form of one of its receptors and is strongly expressed on stimulated lymphocytes. To further understand the role of TNF-alpha, sTNFR2 and other cytokines in the pathogenesis in HPV-related neoplasia, the profiles of serum cytokines in high-risk patients were analyzed for association with anal lesion status. Patients were categorized into 4 groups based on HIV status (HIV-negative vs. HIV-positive with a CD4+ level <200/uL) and anal lesion status [no lesion, low-grade anal squamous intraepithelial lesion (LSIL) vs. high-grade squamous intraepithelial lesion (HSIL)] based on high resolution anoscopy-guided biopsy. Following adjustment for multiplicity, HIV-negative men with HSIL had lower levels of sTNFR2 than HIV-positive men with low CD4 level and HSIL (p=0.02). HIV-positive men with HSIL had higher levels of TNF-alpha than HIV-negative men with HSIL (p<0.001), as well as HIV-positive men with no lesion or LSIL (p=0.03). The levels of other factors, including IL-1beta, IL-2, IL-4, IL-8, IFN-gamma, GM-CSF, sTNFR1 and DR5, were not significantly different between groups. Although the sample size was small, these results suggest that systemic activation of TNF-alpha/sTNFR2 in HIV-positive patients with a low CD4 level may promote the development of HSIL and possibly anal cancer.

Abstract
Sexually transmitted diseases (STDs) occur often among sexually active persons with HIV infection. Incident STDs may complicate the course of HIV infection and potentiate HIV transmission in the coinfected individual by mucosal disruption and an increase in HIV concentration in ulcers and involved mucous membranes. Conducting ongoing periodic sexual risk assessments in HIV-positive patients in routine medical care is critical to identifying asymptomatic infections. HIV clinicians should be familiar with updated recommendations for screening, diagnosis, and treatment of bacterial and viral STDs, including those specific to HIV infection. This article addresses emerging issues in the management of STDs in HIV-infected persons and summarizes the latest evidence that can be applied to clinical decision-making in this population.

Abstract
OBJECTIVE To evaluate the incidence rates of anal cancer over the HIV epidemic and assess the impact of HAART use on anal cancer events. METHODS We evaluated the incidence of and factors associated with anal cancer using longitudinal data from the prospective U.S. Military Natural History Study (1985-2008). Poisson regression and Cox proportional hazard models were utilized. RESULTS Among 4506 HIV-infected men with 37 806 person-years of follow-up, anal cancer rates (per 100 000 person-years) increased five-fold, from 11 in the pre-HAART to 55 in the HAART era (P = 0.02). Rates continued to increase, reaching 128 in 2006-2008. Persons with HIV infection for more than 15 years had a 12-fold higher rate than those with less than 5 years (348 vs. 28, P < 0.01). At cancer diagnosis (n = 19), median age was 42 years, median CD4 cell count was 432 cells/microl, 74% had a CD4 nadir cell count less than 200 cells/microl, 42% had a prior AIDS event, and 74% had received HAART. From separate models, prior AIDS event (hazard ratio 3.88, P = 0.01) and lower CD4 nadir (hazard ratio 0.85 per 50 cell, P = 0.03) were associated with anal cancer, with a trend for a history of gonorrhea (hazard ratio 2.43, P = 0.07). Duration of HAART use was not associated with a reduced risk of anal cancer (hazard ratio 0.94, P = 0.42). CONCLUSION Incidence rates of anal cancer have progressively increased during the HIV epidemic. Persons with a longer duration of HIV infection have a substantially higher rate of anal cancer. As HIV-infected persons are experiencing longer life expectancies and HAART does not appear protective of anal cancer, studies on preventive strategies are needed.

Abstract
Human papillomavirus (HPV) infection is commonly found in the genital tract of men and women with or without any clinical lesion. The association of HPV DNA with several different ano-genital cancers other than cervical has been reported for the vulva, vagina, anus and penis. HPV DNA has also been identified in head and neck cancers in the oral cavity, the oropharynx and the larynx in both sexes. In men, 80-85% of anal cancers and close to 50% of penile cancers are associated with HPV infection. In women, HPV DNA is prevalent in 36-40% vulvar cancer cases and close to 90% of vaginal cancers. There is limited data available on the natural history and HPV-related diseases in the genital tract in men, although studies are ongoing. Efficacy of HPV vaccines in the prevention of HPV infection and disease among men also remains unknown. Among HPV DNA positive ano-genital cancer cases, HPV-16 is the most frequently found followed distantly by HPV-18. In benign HPV-related diseases such as genital warts or recurrent respiratory papillomatosis HPV-6 and 11, the two most frequent non-oncogenic types, are the predominant types detected. Oncogenic types are rarely detected. In this article we summarize and review studies describing the natural history of HPV infections among men and its impact on HPV related disease in women. We summarize the evidence linking HPV in the epidemiology and etiology of cancers of the vulva, vagina, anus and oropharynx and present recent estimates of the burden of and HPV type distribution in genital warts and in cases of HPV infection of the airways.

Abstract
Anal cancer is rare and this helps to explain why anal pre-neoplastic conditions are poorly understood, especially with regard to their natural history and management. Anal intraepithelial neoplasia is closely linked to human papillomavirus infection and is particularly common in homosexuals and in immunosuppressed patients, especially those with HIV/AIDS. The high regression rates of low-grade anal intraepithelial neoplasia may simply reflect inconsistent pathologic reporting. Higher grades of anal intraepithelial neoplasia may remain static for long periods of time in immunocompetent patients, but those with HIV/AIDS show early and rapid malignant transformation. In general, most anal pre-neoplastic conditions are best diagnosed by biopsy and treated by surgical excision, although local recurrence is a problem. In anal Paget's disease, it is important to ascertain, at the time of diagnosis, whether it is due to a primary in-situ apocrine-type of neoplasia of the anus or if the disease is secondary to an invasive primary carcinoma of the rectum.

Abstract
Anogenital cancers are closely associated with human papillomavirus (HPV), and HPV-infected individuals, particularly those with high-grade dysplasias, are at increased risk for cervical and anal cancers. Although genomic instability has been documented in HPV-infected keratinocytes, the full spectrum of genetic changes in HPV-associated lesions has not been fully defined. To address this, we examined an HPV16-transformed foreskin keratinocyte cell line, 16-MT, by GTG-banding, spectral karyotyping (SKY), and array comparative genomic hybridization (array CGH); these analyses revealed multiple numerical, complex, and cryptic chromosome rearrangements. Based on GTG-banding, the 16-MT karyotype was interpreted as 78-83,XXY,+add(1)(p36.3),+3,+4,+5,+5,+7,+8,+i(8)(q10)x2,+10,?der(12),der(13;14)(q10;q10),+15,+16,add(19)(q13.3),+21,+21,-22[cp20]. Multicolor analysis by SKY confirmed and further characterized the anomalies identified by GTG banding. The add(1) was identified as a der(1)(1qter-->1q25::1p36.1-->1qter), the add(19) as a dup(19), and the der(12) interpreted as a der(11) involving a duplication of chromosome 11 material and rearrangement with chromosome 19. In addition, previously unidentified der(9)t(9;22), der(3)t(3;19), and der(4)t(4;9) were noted. The 16-MT cell line showed losses and gains of DNA due to unbalanced translocations and complex rearrangements of regions containing known tumor suppressor genes. Chromosomal changes in these regions might explain the increased risk of cancer associated with HPV. Also, array CGH detected copy-number gains or amplifications of chromosomes 2, 8, 10, and 11 and deletions of chromosomes 3, 4, 11, and 15. These results provide the basis for the identification of candidate oncogenes responsible for cervical and anal cancer in amplified regions, and for putative tumor suppressor genes in commonly deleted regions like 11q22-23. Furthermore, these data represent the first full characterization of the HPV-positive cell line 16-MT.

Abstract
Human papillomavirus (HPV) is one of the most common sexually transmitted infections and a significant cause of anogenital malignancies, precancer lesions, and cutaneous disease. Human immunodeficiency virus (HIV)-positive individuals have a higher prevalence of HPV infection and HPV-associated anogenital disease compared to age-matched HIV-negative controls. Data suggest that there has been little reduction in HPV-associated disease since the introduction of highly active antiretroviral therapy (HAART). The authors believe that cervical and anal cancer screening using Pap tests should be offered to all HIV-positive individuals, but the infrastructure to identify (via colposcopy and high-resolution anoscopy) and treat precancer lesions must be present. Treatment of HPV-associated anogenital disease depends on the size, location, and grade of the lesion, whereas a variety of ablative and excisional therapies are available. Prophylactic and therapeutic HPV vaccines are promising as future interventions for disease control in at-risk populations such as HIV-infected women and men.

Abstract
The aim was to determine whether specific gains of chromosome 3q and laminin-5gamma2-chain expression can improve early detection of invasive capacity in precancerous and squamous cell carcinoma of the vulva (VSCC). Six VSCC and three precancerous lesions were studied. Multicolor fluorescence in situ hybridization (FISH) probe sets were applied to nuclei suspensions prepared from archival material using the Hedley method. The probe panel consists of the centromers of chromosome 7, chromosome 3, and the TERC gene residing on the long arm of chromosome 3. Laminin-5gamma2-chain immunohistochemical analysis was performed on corresponding specimens and was expressed only in the VSCC. The genome-specific FISH analysis revealed 3q amplification in 43% of the nuclei analyzed for the VSCC and 22% of the nuclei for the precancerous lesions. Low-level 3q amplifications were found in precancerous lesions with an average fold increase of 1.15 for 3q. The invasive lesions showed higher average fold increases for 3q, averaging 1.32. Laminin-5gamma2-chain protein was expressed only in VSCC, whereas 3q gains were observed both in precancerous lesions and in VSCC, indicating that gain of chromosome 3q is an early and consistent event during carcinogenesis of VSCC.

Abstract
Before the introduction of highly active antiretroviral therapy (HAART), several studies demonstrated a high prevalence of human papillomavirus (HPV) infection and associated anal intraepithelial neoplasia (AIN) in men who have sex with men, particularly in human immunodeficiency virus (HIV)-infected men with low CD4+ cell counts. Similarly high levels of anal HPV infection and AIN have been found in HIV-positive women. HIV-positive men and women are at an increased risk of developing anal cancer compared with the general population. Data suggest that there has been no reduction in the incidence of AIN after the introduction of HAART. Screening efforts have the potential to decrease the incidence of invasive anal cancer, and cost-effectiveness analyses have demonstrated the utility of anal cancer screening in select populations. Treatment for AIN remains challenging, but AIN is easier to treat when the lesions are small, and it is likely that a screening program would identify affected individuals at an earlier stage of disease.

Abstract
Squamous cell carcinoma of the vulva is a disease of significant clinical importance, which arises in the presence or absence of human papillomavirus. We used comparative genomic hybridisation to document non-random chromosomal gains and losses within human papillomavirus positive and negative vulvar cancers. Gain of 3q was significantly more common in human papillomavirus-positive cancers compared to human papillomavirus-negative cancers. The smallest area of gain was 3q22-25, a chromosome region which is frequently gained in other human papillomavirus-related cancers. Chromosome 8q was more commonly gained in human papillomavirus-negative compared to human papillomavirus-positive cancers. 8q21 was the smallest region of gain, which has been identified in other, non-human papillomavirus-related cancers. Chromosome arms 3p and 11q were lost in both categories of vulvar cancer. This study has demonstrated chromosome locations important in the development of vulvar squamous cell carcinoma. Additionally, taken together with previous studies of human papillomavirus-positive cancers of other anogenital sites, the data indicate that one or more oncogenes important in the development and progression of human papillomavirus-induced carcinomas are located on 3q. The different genetic changes seen in human papillomavirus-positive and negative vulvar squamous cell carcinomas support the clinicopathological data indicating that these are different cancer types.
