Human papillomavirus (HPV) is a common infection in kidney transplant recipients. HPV causes cervical, anal, vulvar, vaginal, penile and head and neck cancers. Kidney transplant recipients have a disproportionate burden of disease given prolonged immunosuppression. Given the long pre-invasive state of precancer lesions such as cervical intraepithelial neoplasia (CIN) and anal intraepithelial neoplasia (AIN) most HPV-cancers are preventable with screening and targeted treatment of disease. Pre-transplant vaccination of age-eligible kidney transplant recipients is otherwise ideal...

The recent success of immunotherapies has demonstrated the potency of tumor-specific immune cells in mediating tumor rejection and generating durable tumor immunity. Our understanding of the scientific basis of these responses results from the confluence of a better comprehension of the cancer immunoediting process and the revolution in next generation sequencing of cancer genomes. Recent evidence suggests that T cell specificity for cancer cell expressed mutant proteins - termed neoantigens - is an important component of immune mediated tumor rejection...

HPV-associated head and neck squamous cell carcinoma (HNSCC), more specifically the incidence of oropharyngeal cancer, is dramatically increasing in industrialized countries. According to what has been learned from anogenital vaccination programs, there are reasons to believe that current human papillomavirus (HPV) vaccinations may be potentially effective also against HNSCC. However, before specific results on HNSCC are available, one must keep in mind that carcinogenesis in the head and neck region may differ from that of the anogenital tract...

Despite current therapy, head and neck squamous cell carcinomas (HNSCCs) arising from various mucosal sites of the upper aero-digestive tract frequently relapse in a loco-regional manner and have a poor prognosis. Our objective was to validate an innovative mucosal route of vaccination using plasmo virus-like particles (pVLPs) in a pre-clinical orthotopic model of HNSCCs. For this purpose, we used pVLP-E7, that are plasmid DNA encoding retroviral virus-like particles carrying a truncated E7 oncoprotein from HPV-16 as antigen model, to vaccinate mice bearing pre-established TC-1 tumors implanted into the buccal mucosa...

Cytoreductive surgery is an approach to cancer treatment that aims to reduce the number of cancer cells via resection of primary tumor or metastatic deposits, in an effort to minimize a potentially immunosuppressive tumor burden, palliate symptoms, and prevent complications. Furthermore, it provides a platform for investigation of biomarkers with the goal of optimizing immunotherapy to reverse the immunosuppressive tumor microenvironment and enhance adaptive immune responses. Ultimately, our group aims to exploit the concept that successful cancer therapy is dependent upon an effective immune response...

Squamous cell carcinoma of the head and neck (SCCHN) accounts for 3% of all cancers. Most patients present with locally advanced disease, where multimodality therapies are used with curative intent. Despite favorable early local treatment results, about one third of the patients will eventually develop metastatic disease. Immunotherapy offers a novel therapeutic strategy beyond cytotoxic chemotherapy, with initial approvals in melanoma and non-small-cell lung cancer. HPV-associated SCCHN is a distinct subset, with unique epidemiology and treatment outcomes...

The importance of HPV in world healthy is high, in fact high-risk HPV types contribute significantly to viral associated neoplasms. In this article we will analyze vary expression of HPV in oral cavity both benign and malignant, their prevalence and the importance in early diagnosis and prevention. The classical oral lesions associated with human papillomavirus are squamous cell papilloma, condyloma acuminatum, verruca vulgaris and focal epithelial hyperplasia. Overall, HPV types 2, 4, 6, 11, 13 and 32 have been associated with benign oral lesions while HPV types 16 and 18 have been associated with malignant lesions, especially in cancers of the tonsils and elsewhere in the oropharynx...

Several human papilloma viruses (HPV) are known to cause malignant transformation. The high-risk type HPV 16 is associated with cervical carcinoma and head and neck squamous cell carcinoma. HPV 16-positive tumor cells exclusively carry the HPV 16 oncogenes E6 and E7. These oncogenes appear as excellent targets for an adoptive immunotherapy. We here addressed the question whether specific T cells from HPV-vaccinated healthy volunteers could be especially suitable for an HPV-specific cellular immunotherapy. Of note, vaccines contain HPV 16...

HPV persistence is necessary for the development of anogenital cancer. Studies show that cervical and anal HPV infections in women and in men who have sex with men are common. Clearance of HPV infection is similarly common; few individuals show persistence unless they are HIV-infected. HIV strongly influences the development of cervical and anal cancer, as well as their pre-malignant counterparts. Women with cervical and vulvar HPV-associated lesions have higher rates of anal cancer than the general population...

Human Papillomavirus (HPV) contributes to the most common sexually transmitted infections, with repeated and persistent infection with particular types causing disease in both men and women. Infection with low-risk HPV types can lead to genital warts and benign lesions of the oral cavity, while high-risk types can cause various HPV-related malignancies. The incidence of head and neck cancer has been rising in the past number of decades mostly due to oropharyngeal cancer linked to HPV infection. HPV vaccination has been shown to be effective for cervical and other anogenital HPV-related cancers, and there is significant potential for HPV vaccination to prevent oropharyngeal cancers, given that the HPV types implicated in this disease can be protected against by the HPV vaccine...

Human papillomavirus (HPV), particularly HPV16 and HPV18, can cause cancers in diverse anatomical sites, including the anogenital and oropharyngeal (throat) regions. Therefore, development of safe and clinically effective therapeutic vaccines is an important goal. Herein, we show that a recombinant fusion protein of a humanized antibody to CD40 fused to HPV16.E6/7 (αCD40-HPV16.E6/7) can evoke HPV16.E6/7-specific CD8(+) and CD4(+) T-cell responses in head-and-neck cancer patients in vitro and in human CD40 transgenic (hCD40Tg) mice in vivo The combination of αCD40-HPV16...

The important goal of immunization programs in many countries is the reduction of the incidence of cervical cancer using either the quadrivalent (Silgard/Gardasil) or the bivalent (Cervarix) HPV (human papillomavirus) vaccine. Nevertheless, HPV infection is associated with the development of cancers of anus, vagina, vulva and penis, and cancers of the head and neck and genital warts, too. Large trials for both vaccines find efficacy against HPV-related infection and different HPV associated diseases.Infection with HPV and diseases caused by HPV are common in boys and men, too...

Head and neck squamous cell cancer (HNSCC) is a malignancy with a rapidly changing demographic profile, given the recent epidemic of human papilloma virus related cancers. Most patients present with locally advanced disease and receive combination therapeutic approaches with curative potential, albeit with significant toxicity. Up to a third of patients, however, will eventually develop recurrent or metastatic disease. The prognosis of such patients is dismal, as palliative treatment options remain limited...

Interest in combining radiotherapy and immune checkpoint therapy is growing rapidly. In this study, we explored a novel combination of this type to augment antitumor immune responses in preclinical murine models of melanoma, neuroblastoma, and head and neck squamous cell carcinoma. Cooperative effects were observed with local radiotherapy and intratumoral injection of tumor-specific antibodies, arising in part from enhanced antibody-dependent cell-mediated cytotoxicity (ADCC). We could improve this response by combining radiation with intratumoral injection of an IL2-linked tumor-specific antibody (termed here an immunocytokine), resulting in complete regression of established tumors in most animals associated with a tumor-specific memory T-cell response...

Acid ceramidase has been identified as a promising target for cancer therapy. One of its most effective inhibitors, LCL521, was examined as adjuvant to photodynamic therapy (PDT) using mouse squamous cell carcinoma SCCVII model of head and neck cancer. Lethal effects of PDT, assessed by colony forming ability of in vitro treated SCCVII cells, were greatly enhanced when combined with 10 µM LCL521 treatment particularly when preceding PDT. When PDT-treated SCCVII cells are used to vaccinate SCCVII tumor-bearing mice (PDT vaccine protocol), adjuvant LCL521 treatment (75 mg/kg) resulted in a marked retardation of tumor growth...

Human papillomavirus (HPV) infection is linked with several cancers such as cancer cervix, vagina, vulva, head and neck, anal, and penile carcinomas. Although there is a proven association of HPV with these cancers, questions regarding HPV testing, vaccination, and treatment of HPV-related cancers continue to remain unanswered. The present article provides an overview of the HPV-associated cancers.

Most patients with head and neck squamous cell cancer (HNSCC) will present with advanced disease characterized by poor prognosis and limited treatment options. Our growing understanding of the complex crosstalk between tumor cells and the immune system has facilitated the development of promising therapies targeting immune checkpoints, such as programmed death 1 and the cytotoxic T-lymphocyte antigen 4, which are producing considerable clinical responses. However, HNSCC tissues use diverse strategies to avoid immunosurveillance, thus limiting our ability to fully harness the immune system to achieve consistent and durable antitumor activity...

Human papillomavirus (HPV) is a common sexually transmitted virus and an important etiologic factor in head and neck cancers. HIV-infected individuals are at increased risk of developing oropharyngeal cancers (OPC) compared with the general population. HPV-positive OPC are also increasingly a significant cause of morbidity and mortality for HIV-infected individuals in the era of effective combination antiretroviral therapy. The epidemiology and natural history of oral HPV infection have not been well established, but it appears that oral HPV infection is less common than anal infection, and more common among HIV-infected persons than the general population...

IMPORTANCE: Human papillomavirus (HPV) is a preventable disease that plays a causative role in a significant proportion of malignant neoplasms of the head and neck. Inner-city populations are at risk for HPV-related oropharyngeal cancer, are least likely to receive HPV vaccination, and report a lack of information regarding HPV. OBJECTIVE: To determine whether an educational platform affects knowledge, attitudes, and practices regarding HPV vaccination in an inner-city community...
