Cutaneous beta HPVs, sun exposure and risk of squamous and basal cell skin cancers in Australia. Cancer Epidemiol Biomarkers Prev 2021; 31:614-624. [PMID: 34933956 DOI: 10.1158/1055-9965.epi-21-1000] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2021] [Revised: 10/24/2021] [Accepted: 12/07/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Sun exposure causes cutaneous squamous (SCC) and basal cell (BCC) carcinomas. Human papillomavirus (HPV) infection might cause SCC. METHODS We examined associations of beta and gamma HPV infection in skin-swab DNA and serum antibodies with skin cancer risk, and modification of the carcinogenic effects of sun exposure by them, in case-control studies of 385 SCC cases, 832 BCC cases and 1100 controls nested in an Australian prospective cohort study (enrolled 2006-2009). RESULTS Presence of beta-1 and beta-3 HPV DNA appeared to increase risks for SCC and BCC by 30%-40% (P adjusted <0.01). BCC was also associated with genus beta DNA, OR=1.48; 95%CI 1.10-2.00 (P adjusted <0.01). Associations were strengthened with each additional positive beta HPV DNA type: SCC (OR=1.07; 95%CI 1.02-1.12) and BCC (OR=1.06; 95%CI 1.03-1.10), P trend <0.01. Positivity to genus beta or gamma in serology, and genus gamma in DNA, was not associated with either cancer. There was little evidence that any beta HPV type was more strongly associated than others with either cancer. A weaker association of sun-exposure with SCC and BCC in the presence of beta-3 HPVs than in their absence suggests that beta-3 HPVs modify sun exposure's effect. CONCLUSIONS Our substantive findings are at the level of genus beta HPV. Like SCC, BCC risk may increase with increasing numbers of beta HPV types on skin. IMPACT The consistency in our findings that HPV infection may moderate the effects of sun exposure, the main environmental cause of SCC and BCC, merits further investigation.

Abstract
INTRODUCTION Basal cell carcinoma (BCC) is the most common skin cancer in the Caucasian population. It is believed that infections caused by viruses from the genus betapapillomavirus (β-HPV) might be associated with the risk of BCC, but the spread of data on the prevalence of the virus in biopsies is significant. AIM To assess the presence and diversity of β-HPV in skin samples taken from the tumour and a fragment of healthy skin from the patients with BCC, as well as checking the correlation of factors listed below and presence of β-HPV infection in the studied patients. MATERIAL AND METHODS The study was conducted on the skin biopsies from 73 patients with histopathologically confirmed BCC. The following data were collected from patients: sex, age, hair colour and tumour location. Using the polymerase chain reaction (PCR) test, the presence of β-HPV infection was detected in the tested samples. PCR and reverse hybridization assay were also used to genotype 25 types of β-HPV. RESULTS A statistically significant correlation was found between the sex and BCC type, BCC type and tumour location, BCC type and exposure to UV radiation, as well as between the hair colour and tumour location. The correlation between the BCC type and the number of tumours and HPV types detected was also noted. CONCLUSIONS Preliminary studies suggest that one of the risk factors for development of infiltrating lesions is the presence of a single HPV 93 infection, but further research is needed to confirm these assumptions.

Abstract
Non-melanoma skin cancers (NMSC) share similar risk factors with other virus-related cancers, despite the lack of proved causal association between viral infection and NMSC development. We investigated the presence of Merkel cell polyomavirus (MCPyV), Epstein-Barr virus (EBV), and human papillomavirus (HPV) DNA in 83 NMSC fresh-frozen and 16 non-cancerous skin biopsies and evaluated viral infection according to demographical data, histopathological diagnosis, and ultraviolet exposure. Our results showed that 75% of NMSC biopsies were positive for at least one out of three viruses, whereas only 38% of non-cancerous skin biopsies were positive (p = 0.02). Notably, HPV detection was frequent in NMSC (43%) and nearly absent (one sample, 6.7%) in non-cancerous biopsies (p = 0.007). MCPyV was associated with sites of higher exposure to ultraviolet radiation (p = 0.010), while EBV was associated with a compromised immune system (p = 0.032). Our study showed that HPV was strongly associated with NMSC while EBV and MCPyV with other risk factors. Though further studies are required to elucidate the role of viral infection in NMSC development and management, this study supports the possible role of oncogenic viruses in skin cancers, especially HPV.

Abstract
Objectives: To prospectively examine the association between human papilloma virus (HPV) colonization of the colonic mucosa and the development of colorectal polyps (CRPs), and colorectal cancer (CRC) in Saudi Arabia. Methods: A case control study was performed between January 2013 and December 2014. All eligible patients underwent standard diagnostic colonoscopy. Patients with polyps or colorectal cancer were considered cases, while those with any other endoscopic findings were controls. Biopsy samples from polyps and tumors, and/or from normal colonic mucosa were acquired. Human papilloma virus colonization was detected using a hybrid capture technique of samples taken from both normal tissue, and CRPs and CRC. The association between HPV and CRPs/CRC was evaluated. Results: A total of 132 patients were recruited. The mean age was 53 (±15.9) years. Sixty patients had endoscopically detectable CRPs/CRC, and 72 had either inflammation or normal endoscopic evaluations. Only 4 (0.8%) of the 132 samples that were collected and analyzed were positive for the HPV gene. Statistical analysis did not identify any significant association between HPV colonization and the presence of CRPs/CRC. The only significant predictor of detecting CRPs/CRC on colonoscopy was symptomatic presentation (odds ratio=11.072, 95% confidence interval 4.7-26.2, p<0.001). Conclusion: Human papilloma virus colonic colonization is rare in Saudi Arabia. An association between HPV colonization and CRP/CRC development could not be identified in this cohort of patients.

Abstract
Cutaneous human papillomaviruses (HPVs) comprise a large and highly heterogeneous virus group. Some of the cutaneous HPVs of the genus Beta have been suggested as a co-factor in the development of non-melanoma skin cancer (NMSC). The aim of this study was to determine cutaneous HPV prevalence and type-specific distribution in different kinds of skin lesions from Argentine patients visiting Dermatology Departments of three hospitals from Buenos Aires. A cross-sectional analysis was performed. HPV DNA was analyzed in (i) 3 patients with Epidermodysplasia verruciformis (EV) harboring benign lesions (BL) (n = 1) and squamous cell carcinoma (SCC) (n = 4); (ii) 240 non-EV patients harboring: (a) BL (n = 38), (b) Actinic Keratosis (AK) (n = 83), (c) SCC (n = 74), and (d) basal cell carcinoma (BCC) (n = 96). Detection and genotyping of 35 cutaneous HPV DNA was carried out by BGC-PCR and GP5+/6 + PCR followed by reverse line blot assay. In EV patients, Beta types were found in all lesions (5/5), including the potentially high-risk HPV types 5 and 8, mostly in multiple infections. In non-EV patients, cutaneous types were found in 50.0% of BL, 43.4% of AK, 31.1% of SCC, and 16.7% of BCC. Beta HPVs were the most frequently found in all lesions, being present in all AK and SCC cases that were positive for HPV. No type-specific correlation with lesion severity was found. In our series, a wide spectrum of cutaneous HPV types was detected in different skin lesions. A possible role for these HPVs in skin carcinogenesis deserves further study. J. Med.

Abstract
Background: Basal cell carcinoma (BCC) is the most common skin cancer among whites, and several risk factors have been discussed in itsdevelopment and progress. Detection of human papilloma virus (HPV) deoxyribonucleic acid (DNA) BCCs in some studies suggests that the virus may play a role in the pathogenesis of this disease. Several molecular studies showed conflicting reports. Aims: The purpose of this study was to investigate the association between HPV and BCC using polymerase chain reaction (PCR). Materials and Methods: HPV DNA detection was done for 42 paraffin-embedded tissue specimens of BCC and 42 normal skin samples around the lesions by PCR using GP5+/GP6+ primers. Results: HPV DNA was not found in any of the 42 samples of BCC, and only one normal skin sample around the lesions was positive for HPV DNA by PCR. Conclusion: In this study, no statistically significant difference was seen between the presence of HPV DNA in BCC and normal skin around the lesion, and HPV is not likely to have an important role in pathogenesis of BCC.

Abstract
Basal cell carcinoma (BCC) is the most common non-melanoma skin cancer. Exposure to ultraviolet light is an important risk factor for BCC development and the disorder therefore develops commonly on body areas that are more exposed to sunlight, such as the face and neck. It is uncommon in the closed area of the body and quite rare in the perianal and genital regions. Herein, we report a 34-year-old patient with perianal BCC who had no additional risk factors.

Abstract
Accumulating evidence suggests that cutaneous human papillomavirus (HPV) infection is associated with non-melanoma skin cancer (NMSC). Little is known about the natural history of cutaneous HPV. A sub-cohort of 209 men with no NMSC history, initially enrolled in the HPV infection in men (HIM) study, were followed for a median of 12.6 months. Epidemiological data were collected through self-administered questionnaires. Cutaneous HPV DNA was measured in normal skin swabs (SS) and eyebrow hairs (EB) for 25 and 16 HPV types in genera β and γ, respectively. Any β HPV infection was more prevalent in SS (67.3%) compared to EB (56.5%, p = 0.04). Incidence in SS was higher than 20 per 1,000 person-months for HPV types 4, 5, 23, 38 and 76. Median duration of persistence of β and γ HPV infection was 8.6 and 6.1 months in EB, respectively, and 11.3 months and 6.3 months, in SS, respectively. Older age (>44 years vs. 18-30 years) was significantly associated with prevalent (SS OR = 3.0, 95% CI = 1.2–7.0) and persistent β HPV infection (EB OR = 6.1, 95% CI = 2.6–14.1). History of blistering sunburn was associated with prevalent (OR = 2.8, 95% CI = 1.3–5.8) and persistent (OR = 2.3, 95% CI = 1.2–4.6) β HPV infection in SS. Cutaneous HPV is highly prevalent in men, with age and blistering sunburn being significant risk factors for cutaneous β HPV infection.

Abstract
Human papillomavirus (HPV) infection has been demonstrated in some of the nonmelanoma skin cancers as well as in precancerous lesions. Multiple infections of mucosal high-risk HPV may contribute to the onset of digital Bowen's disease through, if any, digital-genital transmission. We screened for the presence of the mucosal HPV DNA in patients with extragenital Bowen's disease (n = 30), squamous cell carcinoma (n = 11), bowenoid papulosis (n = 9), verrucous carcinoma (n = 1), actinic keratosis (n = 5), and basal cell carcinoma (n = 5). We used a PANArray HPV Genotyping Chip for high-risk and low-risk mucosal types. Genotyping data was confirmed using a conventional direct DNA sequencing method. Two cases of extragenital Bowen's disease were positive for types 16 and 33 of mucosal HPV, respectively. None of the squamous cell carcinoma cases were positive. Neither patients with digital Bowen's disease (n = 5) nor those with squamous cell carcinoma (n = 3) showed any mucosal high-risk HPV. Mucosal high-risk HPV DNA was confirmed in 5 (55.6%) of the 9 patients with bowenoid papulosis. HPV 16 was most prevalent (n = 3), while the DNA of HPVs 35 and 67 was detected in one sample for each of the two types. Our study demonstrated that two (6.7%) of the patients with 30 extragenital Bowen's disease were positive for types 16 and 33 of mucosal HPV, respectively. HPVs belonging to the mucosal high-risk group may participate in the development of extragenital Bowen's disease. However, we could not find any relationship between the mucosal high-risk HPV and Bowen's disease or squamous cell carcinoma in the fingers.

Abstract
BACKGROUND Cutaneous human papillomavirus (HPV) infections seem to be associated with the onset of actinic keratosis (AK). This study compares the presence of cutaneous HPV types in eyebrow hairs to those in tissues of normal skin and skin lesions of 75 immunocompetent AK patients. METHODS Biopsies from AK lesions, normal skin and plucked eyebrow hairs were collected from each patient. DNA from these specimens was tested for the presence of 28 cutaneous HPV (betaPV and gammaPV) by a PCR based method. RESULTS The highest number of HPV prevalence was detected in 84% of the eyebrow hairs (63/75, median 6 types) compared to 47% of AK lesions (35/75, median 3 types) (p< 0.001) and 37% of normal skin (28/75, median 4 types) (p< 0.001), respectively. A total of 228 HPV infections were found in eyebrow hairs compared to only 92 HPV infections in AK and 69 in normal skin. In all three specimens HPV20, HPV23 and/or HPV37 were the most prevalent types. The highest number of multiple types of HPV positive specimens was found in 76% of the eyebrow hairs compared to 60% in AK and 57% in normal skin. The concordance of at least one HPV type in virus positive specimens was 81% (three specimens) and 88-93% of all three combinations with two specimens. CONCLUSIONS Thus, eyebrow hairs revealed the highest number of cutaneous HPV infections, are easy to collect and are an appropriate screening tool in order to identify a possible association of HPV and AK.

Abstract
PURPOSE To understand the pathogenesis of cervical cancer (CC) associated with polarity protein αPKC and the potential roles of αPKC in clinical management of CC. METHODS Tissue samples were collected from women who received colposcopy biopsy or hysterectomy surgery, including 9 CIN1, 8 CIN2, 15 CIN3, and 12 invasive cervical squamous cancer (ICC). 16 normal controls were from the normal region of tumor samples, HE and immunofluorescence staining of αPKC were performed on these samples. ANOVA and Kruslal-wallis test were used to quantitate the abnormal distribution and expression level of αPKC among different cervical lesions. RESULTS Disruption of polarized apical localization and increased cytoplasmic accumulation of αPKC were identified in cervical lesions. In normal cervical epithelium, αPKC was detected on the apical membrane of endocervical columnar epithelial cells and of exocervical epithelial cells located at basal layer of squamous epithelium. While in squamous metaplasia, a precancerous lesion of cervical neoplasia, the polarized apical membrane localization of αPKC was disrupted, and intensed cytoplasmic accumulation was identified in the immature squamous metaplastic cells. Compared with normal cervix, number of epithelial cells with abnormal αPKC distribution was progressively increased in CINs and ICC (P < 0.05), and cytoplasmic accumulation of αPKC was increased in CIN2, CIN3, and ICC compared with CIN1 (P < 0.05). CONCLUSIONS Disruption of polarized apical localization and increased cytoplasmic accumulation of αPKC were associated with CC progression, indicating that precise regulation of αPKC may play important roles in CC progression, and αPKC may be a potential molecular target for clinical diagnoses and treatment of CC.

Abstract
Basal cell carcinoma is the most common human neoplasia. In more than 80% of patients, who are predominantly elderly, it is located in the head-and-neck-area. Basal cell carcinomas in non-UV-exposed areas of the body, such as the anogenital region, are dermatological rarities. We describe an 88-year-old patient with a perianal tumor that was detected during skin cancer screening. Histopathology showed the tumor to be a basal cell carcinoma. Immunohistochemical staining for Ber-EP4 was highly positive, clearly distinguishing the tumor from basaloid anal carcinoma, which is the most important histological differential diagnosis. Additional virological analyses for human papil-lomaviruses (HPV) were negative. Immunohistochemical staining for p16(INK4a) demonstrated strong expression in the cells of the tumor parenchyma. However, p16(INK4a) can also be expressed independently of HPV. The present case shows that all uncertain perianal skin lesions should be biopsied.
