Head and neck squamous cell carcinoma (HNSCC) is the sixth most prevalent cancer worldwide with about 600,000 new cases diagnosed in the last year. The incidence of human papillomavirus-positive head and neck squamous cell carcinoma (HPV-positive HNSCC) has rapidly increased over the past 30 years prompting the suggestion that an epidemic may be on the horizon. Therefore, there is a clinical need to develop alternate therapeutic strategies to manage the growing number of HPV-positive HNSCC patients. TriCurin is a composition of three food-derived polyphenols in unique stoichiometric proportions consisting of curcumin from the spice turmeric, resveratrol from red grapes, and epicatechin gallate from green tea...

Cutaneous warts are known to be recurrent and often resistant to therapy. Resistant warts may reflect a localized or systemic cell mediated immune (CMI) deficiency to HPV. Many modalities of treatment are in use; most of the provider-administered therapies are destructive and cause scarring, such as cryotherapy, chemical cauterisation, curettage, electrodessication and laser removal. Most patient-applied agents like podophyllotoxin have the risk of application-site reactions and recurrence. Thus immunotherapy is a promising modality which could lead to resolution of warts without any physical changes or scarring and in addition would augment the host response against the causative agent, thereby leading to complete resolution and decreased recurrences...

External genital warts (EGWs) resulting from the human papilloma virus (HPV) are a common sexually transmitted infection and cause significant impairments in patient quality of life and sexual well-being. Therapeutic options for EGWs can be provider-assisted, but many patients opt for treatment that can be applied at home. Sinecatechins 10% ointment is a new botanically based patient-administered therapy for EGWs. It is comprised of >85% catechins, green tea polyphenols that have been shown to possess antioxidant, antiproliferative, antiviral, and antitumor properties...

The role of human papillomavirus (HPV) in human disease includes external genital and perianal warts (EGW), with some HPV genotypes having oncogenic potential (i.e., HPV-16 and -18). While green-tea extracts have antitumor and antiproliferative effects in vitro, the mechanism of action of sinecatechins in the treatment of EGW is not well understood. To investigate the role of immune-regulated genes further, an open-label, single institution, prospective study was conducted enrolling patients with clinically diagnosed EGW...

Human papillomavirus (HPV) infection is the most common sexually transmitted virus infection; about 40 out of 150 known HPV genotypes have been associated with genitoanal lesions in the female and male. They have been divided into low-risk (LR) and high-risk (HR) HPV types according to the association of each HPV genotype with genitoanal benign warts, genitoanal cancer and precursor lesions. For the most part, genitoanal HPV infection is equally common in men and in women. Genitoanal HPVs are predominantly transmitted by sexual intercourse...

This review summarizes new treatments from the last seven years employed for the treatment of genital warts caused by human papillomavirus (HPV). Imquimod 3.75% is a new agent with fewer side effects and perhaps a better dosing schedule than imquimod 5%, but is not more effective. Sinecatechins/Polyphenon E 15%, a novel extract from green tea can be effective against genital warts but requires three times a day dosing and is not more effective than existing treatments; the treatment course is 12-16 weeks. Photodynamic therapy combined with other destructive modalities might increase the cure rate for genital warts...

Despite some recent hopeful therapeutic developments such as topical green tea derivatives, the therapy of anogenital warts remains a medical problem. Both physician- and self-administered therapeutic approaches are not fully satisfactory. The high recurrence rates associated with the current therapy of anogenital warts together with their increasing incidence and burden of disease further support the use of the prophylactic quadrivalent VLP HPV 6,11,16,18 vaccine for control of HPV-associated neoplasias in women and men...

OBJECTIVES: Human papillomavirus (HPV) infection is closely associated with the development of more than 95% of cervical cancer. Clinical trials using several chemopreventive agents are underway, but results are inconclusive. Most agents used in trials inhibited the growth of cancer cells in vitro, and about half of patients had some degree of clinical responses; however, the therapeutic effect was confounded by high rates of spontaneous regression and relapse. The selection of nontoxic agents especially food, beverage, and natural products that suppress oncogenic HPV, inhibit malignant transformation, and can additionally be used long term may be important for cervical cancer prevention...

Cervical cancer is the second most common malignant neoplasm in women, in terms of both incidence and mortality rates worldwide. The polyphenolic constituents of tea (Camellia sinensis) have gained considerable attention because of its anti-cancer properties against a variety of cancers. Here we studied the effects of green and black tea polyphenols (GTP and BTP), on cellular proliferation and cell death in the SiHa cells (human cervical cancer) expressing the human papilloma virus (HPV)-16. The result showed that both GTP and BTP inhibited proliferation of cells in dose and time dependent manner...
