The etiology of bladder cancer is known to be associated with behavioral and environmental factors. Moreover, several studies suggested a potential role of HPV infection in the pathogenesis with controversial results. A systematic review was conducted to assess the role of HPV. A total of 46 articles that reported the prevalence of HPV infection in squamous (SCC), urothelial (UC), and transitional cell carcinomas (TCC) were selected. A pooled prevalence of 19% was found, with a significant difference in SCC that was mainly driven by HPV-16. Moreover, infection prevalence in case-control studies showed a higher risk of bladder cancer in HPV-positive cases (OR: 7.84; p-value < 0.00001). The results may suggest an etiologic role of HPV in bladder cancer. HPV vaccine administration in both sexes could be key to prevent the infection caused by high-risk genotypes.

The favorable features of high-risk human papillomavirus (HPV) in the head and neck are limited to those harboring transcriptionally-active HPV, which occur predominantly in the oropharynx (OP). Factors rendering the OP susceptible to HPV oncogenesis are largely unexplored. The role of cytokeratin 7 (CK7) in predisposition to HPV and cancer in the cervix has been evaluated. However, its significance in the H&N is unknown. CK7 immunohistochemistry was performed on a tissue microarray cohort of OP and non-oropharyngeal (NOP) squamous cell carcinomas (SCC) with known clinical follow-up and HPV E6/7 mRNA status. Expression was graded based on the distribution (1 ≤ 33%, 2 = 33-66%, 3 ≥ 66%) and intensity (1 = weak, 2 = strong) with combined score of ≥ 2 considered positive. Survival analysis was performed. Seventy-four NOPSCCs and 204 OPSCCs were studied. HPV was positive in 2.7% of NOPSCCs and 70.9% of OPSCCs. CK7 was positive in 23.0% of OPSCCs and 14.8% of NOPSCCs (p = 0.2), and in 24.1% of HPV positive versus 17.2% of negative patients (p = 0.2). There was no correlation with age, race, gender, HPV status, histologic type, tumor subsite, treatment, stage, or co-morbidities, and CK7 expression was not significantly associated with overall or disease specific survival. In our series, CK7 is positive in ~ 25% of H&N SCCs, although usually only focally. While CK7 has been suspected to be overexpressed selectively in HPV-related OPSCCs due to their origination from tonsillar crypt epithelium, we did not find any significant difference by anatomic H&N subsite, nor by HPV status, for its expression and found no association with patient survival.

Full size image [/article/10.1007/s42764-021-00038-x/figures/1] The findings described above support the statement that HPV infection is common, but, in comparison, cervical cancer is quite rare, leading to the conclusion that HPV infection alone is not sufficient to produce cancer, as tumor development and progression require the contribution of multiple factors. Among the risk factors for cancer development and progression in women infected with HR HPV are the determinants of persistent infection, as it is well established that only women in whom HR HPV infection persists are at risk for cervical lesions that may progress to cancer (Banister et al. 2015 and references therein). HPV persistence has also been linked to HPV-mediated disease in men (Bettampadi et al. 2020 [/article/10.1007/s42764-021-00038-x#ref-CR16]). This is an important area of study, because in principle, if we were able to determine at a single visit whether or not an incident HR HPV infection will persist, we could target HPV-mediated cancer surveillance resources to the people who present with persistent infection. Our own (unpublished) findings support the concept that women with persistent HPV infection fail to mount a strong immune response to HPV. In turn, immune responses to HPV are likely to be influenced by HLA and SNP profiles, both of which have been linked with cervical cancer susceptibility (Chen et al. 2014; Das Gosh et al. 2017). Among the many SNPs that have relevance for cervical cancer development, the Arg/Pro TP53 polymorphism at codon 72 has received considerable attention, as the homozygote Arg/Arg phenotype is associated with a higher risk of developing cervical cancer, at least in certain populations (Ojeda et al. 2003; Chuery et al. 2017). TP53 codon 72 polymorphism has been connected with higher HPV E6/E7 expression, which appears to correlate with the Arg/Arg genotype (Chuery et al. 2017). Despite the continuing controversies in this area, there is evidence that this particular polymorphism plays a role in cervical cancer development, albeit with additional intervening factors that may modulate its impact in different populations.

The prognostic impact of human papillomavirus (HPV) infection or smoking on oropharyngeal high-grade neuroendocrine carcinoma (HG-NEC) is not established.Retrospective study with patients with oropharyngeal HG-NEC seen at MD Anderson Cancer Center from 1997 to 2020, and previously reported patients with oropharyngeal HG-NEC and known p16 and HPV status from the literature review. Survival was estimated with the Kaplan-Meier method, and survival differences assessed with the log-rank test and Cox proportional hazards models.Thirty patients were included; most had a heavy (≥10 pack-years) smoking history (52%), locoregional disease (stage III-IVB; 77%), and p16-positive tumor (92%). HPV was positive in 65% of tested samples (15/23). Of 24 patients treated with curative intent, the objective response rates was 90% (9/10) and 81% (17/21), respectively, for induction chemotherapy and definitive radiotherapy. During follow-up, 54% (13/24) recurred, mostly (11/13) at distant sites. Median overall survival (OS) was 46 months (95% CI, 14.3 - NA). OS was not associated with HPV status (HR 0.73, P = 0.6) or smoking (HR 1.16, P = 0.8). Among 63 patients with known HPV status after the literature review (19 HPV- and 44 HPV + ), HPV status remained unassociated with OS (P = 0.92).This is the largest retrospective cohort of oropharyngeal HG-NEC. Distant recurrence rate after curative treatment was high, suggesting that multimodality treatment including systemic therapy may benefit patients with locally advanced disease. HPV infection did not affect survival outcomes, therefore should not lead to therapy de-intensification for this histology.

Vulvar squamous cell carcinoma (VSCC) pathogenesis is traditionally defined by the presence or absence of human papillomavirus (HPV), but the definition of these groups and their molecular characteristics remains ambiguous across studies. Here, we present a retrospective cohort analysis of 36 patients with invasive VSCC where HPV status was determined using RNA in situ hybridization (ISH) and polymerase chain reaction (PCR). Clinical annotation, p16 immunohistochemistry (IHC), programmed death ligand-1 (PD-L1) IHC, HPV16 circular E7 RNA (circE7) detection, and RNA-sequencing (RNA-seq) of the cases was performed. A combination of ISH and PCR identified 20 cases (55.6%) as HPV-positive. HPV-status did not impact overall survival (HR: 1.36, 95% CI: 0.307 to 6.037, p=0.6857) or progression-free survival (HR: 1.12, 95% CI: 0.388 to 3.22, p=0.8367), and no significant clinical differences were found between the groups. PD-L1 expression did not correlate with HPV status, but increased expression of PD-L1 correlated with worse overall survival. Transcriptomic analyses (n=23) revealed distinct groups, defined by HPV status, with multiple differentially expressed genes previously implicated in HPV-induced cancers. HPV-positive tumors showed higher global expression of endogenous circular RNAs (circRNAs), including several circRNAs that have previously been implicated in the pathogenesis of other cancers.

Significant variation in human papillomavirus (HPV) prevalence in oropharyngeal squamous cell carcinoma (OPSCC) across countries ranging from 11% in Brazil to 74% in New Zealand has been reported earlier. The aim of this study was to systematically review the most recently published studies on the occurrence of HPV in OPSCC globally. PubMed and Embase were systematically searched for articles assessing the occurrence of HPV+ OPSCC published between January 2016 and May 2021. Studies with a study period including 2015 and the following years were included. Both HPV DNA and/or p16 were accepted as indicators of HPV+ OPSCC. 31 studies were enrolled comprising 49,564 patients with OPSCC (range 12-42,024 patients per study) from 26 different countries covering all continents. The lowest occurrences of HPV+ OPSCC were observed in India (0%) and Spain (10%) and the highest occurrences were observed in Lebanon (85%) and Sweden (70%). We observed great variation in HPV prevalence in OPSCC worldwide varying from 0% to 85%. The highest occurrences of HPV+ OPSCC were found in general in Northern European countries, USA, Lebanon, China, and South Korea. We observed a trend of increase in HPV-positivity, indicating a mounting burden of HPV+ OPSCC.

Ocular adnexal (OA) sebaceous carcinoma is an aggressive malignancy. Oncologic drivers of ocular sebaceous carcinoma are incompletely understood. A retrospective search of our pathology archives for OA sebaceous carcinoma identified 18 primary resection specimens. Immunohistochemistry for p16 and ZEB1 and RNA in situ hybridization for high-risk human papillomavirus (HPV) subtypes were performed. High-risk HPV was demonstrated in 2/11 (18%) cases. p16 overexpression was observed in 10/11 (91%). No association between gender, age at presentation, tumor location, intraepithelial spread, tumor size, and T stage was observed between HPV-driven and nonviral cases. High expression of ZEB1 was observed in the intraepithelial component of 4/14 (28%) cases and in the subepithelial component of 1/13 (7%) cases. ZEB1 overexpression was not associated with HPV-status, T stage, or tumor size. As previously described by others, our findings suggest that a subset of OA sebaceous carcinomas may arise via an HPV-dependent pathway. However, unlike high-risk HPV-driven carcinomas of the oropharynx, we did not identify an association between HPV-status and prognostic features. Furthermore, p16 expression was not a useful surrogate marker for HPV-driven disease. ZEB1 overexpression is not associated with HPV in our cohort of ocular sebaceous carcinoma.

We herein report the treatment outcome of oropharyngeal squamous cell carcinoma (OPSCC) at Kyushu University Hospital, the total number of OPSCC cases, and changes in the proportion of human papilloma virus (HPV)-related carcinomas over time.We performed a retrospective analysis of 237 cases treated for OPSCC at Kyushu University Hospital between 2013 and 2019. We performed HPV-mRNA in situ hybridization and p16 immunohistochemistry.This study included 197 males (82.1%) and 40 females (17.9%). The disease-specific, progression-free and overall survival (OS) were 69%, 62% and 61%, respectively, over the decade-long study period. p16-Immunohistochemistory and highrisk HPV mRNA in situ hybridization were positive in 114 (48.1%) and 105 (44.3%) cases, respectively. The number of HPV-related OPSCC cases increased according to an annual analysis. HPV+ cases had a significantly better prognosis than HPV- cases. In addition, p16+/HPV- cases had a significantly worse prognosis than p16+/HPV+ cases (OS: p = 0.0484). HPV+ OPSCC cases were associated with a younger age (< 60 years old) (p = 0.0429), non-smoker (p = 0.0001), lateral tumor site (< 0.00001), lymphoid metastasis (< 0.0001) and low clinical stage (< 0.0001).The frequency of HPV-related OPSCC cases is increasing in Japan as well as worldwide, and such cases are characterized by no smoking habit, a young age, and a good prognosis. Even in p16+ OPSCC, HPV- cases had a poor prognosis, suggesting the importance of accurate HPV determination. To determine the intensity of treatment for HPV-related and non-related OPSCC, it is necessary to accumulate cases for the accurate HPV determination and comparison of treatment effects.

Primary bladder tumors have a high degree of malignancy. To investigate the expression of human papillomavirus type 16 (HPV-16) in primary bladder tumors and the loss of cell differentiation and to explore the significance of HPV-16 detection, it is expected to be a disease. Treatment provides a theoretical basis.Fifty-seven patients with primary bladder tumors admitted to our hospital from January 2019 to January 2022 were selected as the research subjects, and they were divided into HPV-related groups according to the human papillomavirus (HPV) infection status (n = 28) and HPV unrelated group (n = 29). The general data of patients were collected, the expression of HPV-16 in bladder tissue samples was detected, and the correlation between pathological parameters and HPV-16 expression was analyzed.Among HPV subtypes, HPV 16 subtype accounted for the highest proportion, followed by HPV-18 and HPV-6 subtypes; there was no significant difference in tumor stage (stage 1, stage a, stage 2a) between the HPV-related group and the HPV-unrelated group (stage 1, stage a, and stage 2a). P > 0.05); there was no significant difference in postoperative pathological expression (high expression and low expression) of patients (P > 0.05); there was no statistical difference in age and gender between HPV-related and HPV-unrelated groups (P > 0.05), HPV-related group and HPV-unrelated group compared daily regular drinking and smoking status, the difference was statistically significant (P < 0.05); HPV-16 expression was not correlated with tumor differentiation degree and age of patients (P > 0.05); the area under the curve (AUC) of HPV-16 for judging primary bladder tumor expression and cellular molecular deletion was 0.891, with a sensitivity of 83.94% and a specificity of 88.57%.HPV-16 is an upper, expressed in primary bladder tumors and will participate in the differentiation and loss of cells, which can provide effective guidance and basis for the diagnosis of primary bladder tumors, which is an important factor for judging the pathological stage and prognosis of patients and can provide a theoretical reference for the formulation of therapeutic measures.

Primary carcinomas of the urethra are rare and poorly understood lesions, hence their clinical and pathologic spectrum is not completely defined. We analyzed a series of 130 primary urethral tumors and classified 106 of them as primary urethral carcinomas. The age at diagnosis of patients with primary urethral carcinomas ranged from 42-97years (mean: 69.4yrs.; median: 70yrs). There were 73 males and 33 female patients with a ratio of 2.2:1. In male patients the tumors most frequently developed in the bulbous-membranous segment of the urethra. In female patients the entire length of the urethra was typically involved. Microscopically, they were poorly differentiated carcinoma with hybrid squamous and urothelial features and developed from precursor intraepithelial conditions such as dysplasia and carcinoma in situ, which were frequently present in the adjacent urethral mucosa. High risk HPV infection could be documented in 31.6% of these tumors. Follow-up information was available for 95 patients. Twenty-three patients died of the disease with a mean and median survival of 39 and 21months respectively. Urethral carcinomas are aggressive tumors with high propensity for regional and distant metastases with mean and median survival of 39 and 21months respectively. Our observations have important implications for the management of patients with primary carcinoma of the urethra by defining them as a unique entity linked to HPV infection.

The excellent prognosis of patients with low risk HPV associated oropharyngeal squamous cell carcinoma has led to concerns about overtreatment and excessive toxicity with radiotherapy and cisplatin, leading to interest in de-intensification trials. We investigated whether cetuximab, an EGFR targeting antibody, when combined with radiotherapy would result in a decrease in symptom burden and toxicity with similar efficacy when compared to weekly cisplatin.XXXX, a randomised, multicentre trial involving 15 sites in XXXX enrolled patients with HPV associated oropharyngeal squamous cell carcinoma, AJCC 7th edition Stage III (excluding T1-2N1) or stage IV (excluding T4 and/or N3 and/or N2b-c if smoking history >10 pack years and/or distant metastases). Patients were randomised (1:1) to receive radiotherapy (70Gy in 35 fractions) with either weekly cisplatin, 7 doses of 40mg/m2 or cetuximab, loading dose of 400mg/m2 followed by 7 weekly doses of 250 mg/m2. The primary outcome was symptom severity assessed by the MD Anderson Symptom Inventory Head and Neck Symptom Severity Scale from baseline to 13 weeks post completion of radiotherapy using the area under the curve (AUC). Trial was registered on ClinicalTrials.gov: XXXX RESULTS: Between 17th June 2013 and 7th June 2018, 189 patients were enrolled, with 92 on cisplatin arm and 90 on cetuximab included in the main analysis. There was no difference in the primary endpoint of symptom severity; difference in AUC cetuximab - cisplatin was 0.05 (95%CI: -0.19, 0.30), p= 0.66. The T-score (mean number of ≥ grade 3 acute adverse events) was 4.35 (SD 2.48) in the cisplatin arm and 3.82 (SD 1.8) in the cetuximab arm, p= 0.108. The 3 -year failure-free survival rates were 93% (95% CI: 86-97%) in the cisplatin arm and 80% (95% CI: 70-87%) in the cetuximab arm (hazard ratio = 3.0 (95% CI: 1.2-7.7); p=0.015.For patients with low risk HPV associated oropharyngeal cancer, radiotherapy and cetuximab had inferior failure-free survival without improvement in symptom burden or toxicity compared to radiotherapy and weekly cisplatin. Radiotherapy and cisplatin remains the standard of care.

Squamous cell carcinoma metastasis of the head and neck with unknown primary tumor (CUP) comprises a diagnostic challenge. Human papillomavirus (HPV) testing on cytologic specimens is gaining increasing focus as this may facilitate an early diagnosis of HPV-induced oropharyngeal carcinoma. This study aimed to prospectively assess PCR-based HPV-DNA testing on FNA smears in a clinical setting.Patients referred to a tertiary Head and Neck Cancer Center with suspected CUP were included from November 2016 to November 2018. Scraped cell material from FNA smears was analyzed for HPV-DNA with PCR using general primers (GP5 + /GP6 +) and correlated with the origin and histology of the primary tumor (oropharynx vs. outside oropharynx or benign tumor). The turn-around time reflecting the workflow for HPV-DNA testing by PCR was also calculated.A total of 93 patients were enrolled in the study. The sensitivity and specificity were 86.7% [95% CI 75.4-94.1%] and 92.0% [95% CI 74.0-99.0%], and the positive and negative predictive values were 96.3% [95% CI 87.3-99.0%] and 74.2% [95% CI 59.9-84.7%], respectively. The turn-around time for HPV testing was a mean four calendar days.HPV-DNA testing on FNA smears can be performed within a reasonable timeframe and can guide for the detection of an HPV-positive oropharyngeal primary tumor in the clinical setting for patients presenting with CUP of the head and neck.
