Relating pre-treatment non-Gaussian intravoxel incoherent motion diffusion-weighted imaging to human papillomavirus status and response in oropharyngeal carcinoma. Phys Imaging Radiat Oncol 2024; 30:100574. [PMID: 38633282 PMCID: PMC11021835 DOI: 10.1016/j.phro.2024.100574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Revised: 03/29/2024] [Accepted: 04/02/2024] [Indexed: 04/19/2024] Open
Abstract
Background and purpose Diffusion-weighted imaging (DWI) is a promising technique for response assessment in head-and-neck cancer. Recently, we optimized Non-Gaussian Intravoxel Incoherent Motion Imaging (NG-IVIM), an extension of the conventional apparent diffusion coefficient (ADC) model, for the head and neck. In the current study, we describe the first application in a group of patients with human papillomavirus (HPV)-positive and HPV-negative oropharyngeal squamous cell carcinoma. The aim of this study was to relate ADC and NG-IVIM DWI parameters to HPV status and clinical treatment response. Materials and methods Thirty-six patients (18 HPV-positive, 18 HPV-negative) were prospectively included. Presence of progressive disease was scored within one year. The mean pre-treatment ADC and NG-IVIM parameters in the gross tumor volume were compared between HPV-positive and HPV-negative patients. In HPV-negative patients, ADC and NG-IVIM parameters were compared between patients with and without progressive disease. Results ADC, the NG-IVIM diffusion coefficient D, and perfusion fraction f were significantly higher, while pseudo-diffusion coefficient D* and kurtosis K were significantly lower in the HPV-negative compared to HPV-positive patients. In the HPV-negative group, a significantly lower D was found for patients with progressive disease compared to complete responders. No relation with ADC was observed. Conclusion The results of our single-center study suggest that ADC is related to HPV status, but not an independent response predictor. The NG-IVIM parameter D, however, was independently associated to response in the HPV-negative group. Noteworthy in the opposite direction as previously thought based on ADC.

Expression of Human Papillomavirus and the p16 Gene in Oral Potentially Malignant Disorders (OPMD): a Comparative Study With Oral Squamous Cell Carcinoma. Appl Immunohistochem Mol Morphol 2023; 31:331-338. [PMID: 37036407 DOI: 10.1097/pai.0000000000001124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 03/12/2023] [Indexed: 04/11/2023]
Abstract
BACKGROUND The incidence of oral squamous cell carcinoma (OSCC) of the tongue is increasing in the younger population without traditional risk habits that lead researchers to find other related factors such as diet and viruses, especially human papillomavirus (HPV). It is noteworthy that many OSCCs develop from oral potentially malignant disorders (OPMDs). Correct diagnosis and timely management of OPMDs may help to prevent malignant transformation, and therefore it is worth seeing the involvement of HPV in OPMDs and oral cancers, as the preventive and curative measures in HPV-induced cancer types are different from the conventional types of OPMDs and OSCCs. Therefore, the main objective of this study was to identify a relationship between HPV and p16 in OPMDs and compare it with OSCC. METHODS This study was conducted on 83 cases of known OSCCs and OPMDs (oral submucous fibrosis, leukoplakia, and oral lichen planus). Assays, such as polymerized chain reaction (PCR) and reverse transcription-PCR, were carried out for HPV and p16 . The results were compared with clinical information and with the literature. The results were analyzed using SPSS 16.0 for windows. RESULTS P16 expression was mostly seen in males than in female patients. Out of 21 cases of keratosis with dysplasia, 19% expressed p16 . Of 26 oral lichen planus patients, 29% showed the p16 gene with immunohistochemistry. Interestingly, a high percentage of OSF cases expressed p16 (48.27%). Minimal expression was observed in OSCC (6.25%). HPV DNA was detected in 2.4% of the total sample. Both p16 and HPV were detected in a single case of OSCC. OPMDs expressed a significant amount of the p16 gene by immunohistochemistry and reverse transcription-PCR technique when compared with malignant lesions, suggesting a possible inactivation of the p16 gene. HPV and p16 are mostly negative in our OSCC sample, exhibiting low prevalence. CONCLUSIONS OPMDs expressed a significant amount of the p16 gene when compared with malignant lesions, suggesting a possible inactivation of the p16 gene. Although OSF expressed p16 , HPV was not detected, suggesting that over-expression could be independent of HPV. OSCC shows low HPV prevalence.

Abstract
BACKGROUND Fine-needle aspiration is used as a diagnostic tool in head and neck oropharyngeal squamous cell carcinoma and its metastases. Prognosis and treatment rely on the presence or absence of the human papilloma virus. The purpose of this study was to validate the performance of the Aptima HPV assay using Hema-Diff stained fine-needle aspiration smears in the diagnosis of human papilloma virus-related oropharyngeal squamous cell carcinoma using a simplified method to obtain tumor cells for testing. METHODS Patients with a diagnosis of squamous cell carcinoma and positive p16 immunohistochemical staining were identified. Aptima Specimen Transport Media was used to remove tumor cells from the Hema-Diff stained slides using a moistened swab. The selected cells were tested for high risk-human papilloma virus using the Aptima HPV assay and Aptima HPV 16 18/45 genotype assay. The results were compared with the p16 immunohistochemical staining of the related cell block and surgical specimens. RESULTS Twenty-one of the 21 (100%) p16-positive cases were found to be positive for high risk-human papilloma virus, whereas 20 of 21 (95%) negative cases were found to be negative for high risk-human papilloma virus using the Aptima HPV assay. CONCLUSION The Aptima HPV assay can be used to detect high-risk human papilloma virus in Hema-Diff stained fine-needle aspiration smears of oropharyngeal squamous cell carcinoma with a sensitivity of 100% and a specificity of 95%. This provides a valuable alternative to p16 immunohistochemical staining of cell block sections that often lack appropriate numbers of tumor cells.

Abstract
The longstanding phrase, traditional risk factors like-smoking, tobacco and alcohol are the only causative agents of oral and oropharyngeal squamous cell carcinoma (SCC) is changing now. Etiological divergence is taking place which we have to know to reach upon an exact cause of the disease. Human papilloma virus (HPV) infection is a well-established cause of oral cancer. Escalating incidence of HPV associated cancer has a strong impact on its management. So, a concern clinician needs to get aware for it. Among various types of HPV, HPV-16 is more frequently associated with oral cancers. HPV detection will become a game changer in management of oral cancers. HPV infection and p16 protein expression has a strong and consistent correlation. Therefore, immunohistochemical analysis of p16 protein can be a surrogate biomarker in high risk groups. This hospital based prospective observational study recruited 180 subjects of oral and oropharyngeal SCC. We underwent immunohistochemical analysis of p16 in biopsy specimen of subjects and studied HPV status and associated environmental, clinical and behavioral factors. We observed 9.4% (17/180) incidence of p16 positivity with female predominance. Our observations showed that its prevalence was higher in urban patients who were non tobacco users, had sexually transmitted disease, early stage (T1-T2), poorly differentiated SCC with nodal metastasis. We conclude that keeping in mind HPV as a cause of oral and oropharyngeal SCC, p16 should be use as a biomarker for its detection in high risk cases.

Abstract
Human papillomavirus (HPV)-related oropharyngeal squamous cell carcinomas (OPSCCs) represent a distinct clinical entity compared with HPV-negative tumors with particular regard to treatment response and survival outcome. The aim of this study was to assess the AmpFire Multiplex HR-HPV tests, for the detection and genotyping of 15 high-risk (HR) HPV types in formalin-fixed, paraffin-embedded (FFPE) samples and identify HPV-driven OPSCC. DNA from 160 OPSCC FFPE specimens plus 23 samples from other head and neck primary sites was tested. Results were compared with those obtained using Linear Array HPV-DNA Genotyping Test. Linear Array and AmpFire Multiplex HR-HPV tests showed, for all samples and specifically for OPSCCs, an overall concordance agreement of 98.9% and 99.4% and a Cohen κ coefficient of 0.972 and 0.984, respectively. A concordance of 100% for HPV16 and HPV18 was observed. The overall agreement between p16INK4a overexpression and HPV detection by the AmpFire Multiplex HR-HPV assay in 145 OPSCC samples was 93.8%, with a Cohen κ coefficient of 0.848. The AmpFire HPV Tests are simple assays for detection and genotyping of HPV-DNA in OPSCC FFPE samples and can be easily implemented in the clinical practice setting for HPV-DNA detection.

Abstract
INTRODUCTION Oropharyngeal cancer is characterized by high morbidity and mortality. Prognostic factors for this cancer are therefore useful to predict overall survival and may provide additional therapeutic targets. OBJECTIVE To evaluate the 5-year overall survival and prognostic factors for oropharyngeal squamous cell carcinoma. METHODS Retrospective cohort (2008-2018) of a cancer referral center. The population of the study was a hospital-based cohort consisting of patients diagnosed with oropharyngeal cancer who underwent surgery and/or adjuvant therapy (radio- and/or chemotherapy). RESULTS A total of 253 patients with oropharyngeal squamous cell carcinoma were analyzed. The mean age was 59.8 ± 11.9 years and there was a male predominance (81.8%). Smoking and alcohol consumption were found in 88.0% and 84.2% of the sample, respectively. The combination of radiotherapy and chemotherapy was the treatment modality in 42.7% of the sample, followed by surgery combined with radio- and chemotherapy in 15.8%. There were 143 deaths (events), the mean survival was 11.55 ± 9.69 months, and the 5-year overall survival rate was 1.1%. Overall survival was lower for clinical stage III/IV (p < 0.001), HPV p16-negative status (p = 0.019), and an interval > 4 weeks between diagnosis and the beginning of treatment (p < 0.007). CONCLUSION Among the prognostic factors analyzed in this cohort, p16-negative status as a poor prognostic indicator and tumor stage III/IV and an interval longer than 4 weeks between diagnosis and the beginning of treatment were significantly associated with lower overall survival.

Abstract
The cytotoxic protein PRF1 is essentially involved in anti-tumour immunity. PRF1 is overexpressed in advanced HPV+ HNSCC and correlates with better OS. PRF1 expression correlates with tumour infiltrating CD8+ t cells and dendritic cells in HPV+ HNSCC. PRF1 expression correlates with gene markers of t cell exhaustion in HNSCC.
Purpose Head and neck squamous cell carcinoma (HNSCC) is a highly invasive malignancy with poor survival. Perforin (PRF1) plays essential roles in host immunity. Our research intended to identify the correlations of PRF1 with clinical prognosis and tumor immune infiltration in HNSCC. Methods We explored PRF1 expression and its associations with the clinical features of HNSCC via the Tumor Immune Estimation Resource (TIMER), Oncomine and The Cancer Genome Atlas (TCGA) databases. The prognostic value of PRF1 for HNSCC was further explored by Kaplan–Meier plotter and TIMER. Finally, the relation between PRF1 and immune infiltration in HNSCC was estimated via CIBERSORT and TIMER. Results PRF1 expression was remarkably elevated in HNSCC and associated with clinical stage and HPV infection. High PRF1 expression predicted favorable outcomes in HNSCC, especially in HPV+ HNSCC. Moreover, higher infiltration of CD8+ T cells and CD4+ T cells were found in the PRF1high group of HNSCC. PRF1 expression in HNSCC was strongly correlated with infiltrating CD8+ T cells and dendritic cells (DCs), with higher relevance in HPV+ HNSCC. Conclusion Our findings suggested that PRF1 could be a novel prognostic biomarker in HNSCC and that its expression was related to immune cell infiltration, which was impacted by HPV status.

Abstract
PURPOSE OF REVIEW The 8th edition tumor, node, metastasis (TNM) classification (TNM-8) introduced a new classification for human papillomavirus (HPV)-mediated oropharyngeal carcinoma (HPV+ OPC). This review summarizes its potential therapeutic implications focusing on literature published since 2018. RECENT FINDINGS The following are active research areas involved in clinical care and therapy relevant to TNM-8: tumor HPV testing and its clinical implications; stage I disease: treatment selection and lessons learned from recent deintensification trials; emerging strategies addressing stage II and III disease. SUMMARY The TNM-8 classification depicts prognosis of HPV+ OPC much more reliably compared with TNM-7. Among the advantages in outcome comparison and stratification for clinical trial entry and conduct, it also enables more satisfactory individual patient consultation to adequately estimate prognosis, and facilitates clinical and translational research. However, clinicians must remain mindful that the TNM classification is not a guideline for treatment but, instead, provides a framework for clinical research and treatment decision-making. The TNM-8 has potential to improve risk-tailored treatment algorithms for HPV+ OPC including selection of treatment modality (primary trans-oral surgery vs. radiotherapy, addition of chemotherapy) and adjusting the intensity of approaches. To realize these goals fully, it is apparent that the TNM-8 needs to evolve further.

Abstract
Introduction: P16 overexpression is considered as a good prognostic marker for oropharyngeal squamous cell carcinoma. However, there are very few literatures on the prevalence and outcomes of p16 overexpression in non-oropharyngeal squamous cell carcinoma and benign head and neck tumors. The aim of our study was to estimate the hospital based prevalence of p16 positive laryngeal and pharyngeal tumors and to compare it with the prevalence of p16 expression in the non tumor tissue (tonsils). Methods: This was a descriptive cross-sectional study. Cases of all genders >15 years presenting with malignant or benign tumors of larynx and all the subsites of pharynx were included in the study for evaluation of p16 expression by immunohistochemistry. Tonsillar tissue of cases undergoing tonsillectomy for recurrent acute tonsillitis were taken as non-tumorous tissue to evaluate for p16 expression. Results: A total of 48 cases were included in our study with 24 cases having different tumors of head and neck region and 24 cases having recurrent acute tonsillitis who were kept under non-tumor group. Eight cases (33.3%) in the tumor group showed positive stain for p16 in IHC. In non tumor group, 7 cases (29.1%) showed positive IHC staining for p16. Conclusions: P16 expression can be present in both benign and malignant tumors of various subsites of head and neck region and also in tonsillar tissue affected by inflammation.

Abstract
The many changes made to the head and neck (HN) chapters of the eighth edition of the American Joint Committee on Cancer (AJCC) and Union for International Cancer Control (UICC) cancer staging manuals have resulted in confusion from clinicians and radiologists. These changes have even raised concerns for validity. In prior staging manual updates, the changes made largely provided simplification of more complex staging details. The current eighth edition of the AJCC/UICC staging manuals introduced greater granularity to HN tumor staging. This reflects the current understanding of pathophysiology of these cancers and is necessary to create a more accurate prognosis for these patients. The most commonly encountered example of manual changes is the separate staging of viral-associated oropharyngeal squamous cell carcinoma from tobacco and alcohol use-associated squamous cell carcinoma. While anatomic imaging is critical for HN cancer staging, and frequently outweighs clinical examination, some changes to staging make it impossible for a stage to be assigned until surgical resection is performed. In all, the AJCC/UICC eighth edition changes, the impact on radiologists, and the rationale behind the changes will be discussed. Additionally, opportunities for radiologists to contribute to research that may influence the next edition of AJCC/UICC cancer staging manuals will be proposed.

[PMID: 31036418 DOI: 10.1016/j.amjoto.2019.04.015] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2018] [Revised: 04/15/2019] [Accepted: 04/22/2019] [Indexed: 10/27/2022]
Abstract
OBJECTIVE To investigate the genetic and epigenetic differences between human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) and HPV-negative OPSCC. METHODS Microarray data of HPV-positive and -negative OPSCC were retrieved from NCBI GEO datasets. Differentially expressed genes (DEGs) and differentially expressed miRNAs (DE-miRNAs) were identified by performing differential expression analysis. A functional enrichment analysis was performed to explore the biological processes and signaling pathways that DEGs and DE-miRNAs were involved in, respectively. A protein-protein interaction (PPI) network of DEGs was constructed to identify hub genes. miRNA-target network and miRNA-miRNA functional synergistic network were each constructed in order to identify risk-marker miRNAs. An miRNA-target-pathway network was constructed in order to explore the function of identified risk-marker miRNAs. RESULTS Microarray data from 3 datasets (GSE39366, GSE40774, and GSE55550) was included and analyzed. The PPI network identified 3 hub genes (VCAM1, UBD, and RPA2). MiR-107 and miR-142-3p were found to play the most significant role in both the DE-miRNA-target network as well as in the miRNA-miRNA functional synergistic network. MiR-107 was involved in HPV-induced tumorigenesis by targeting many genes (CAV1, CDK6, MYB, and SERPINB5) and regulating the p53 signaling pathway, the PI3K-Akt signaling pathway, and the autophagy pathway. In addition, miR-142-3p was implicated in HPV-induced tumorigenesis by targeting the PPFIA1 gene and regulating transcriptional dysregulation and other cancerous pathways. CONCLUSION Three genes (VCAM1, UBD, and RPA2), two miRNAs (miR-107 and miR-142-3p), and four pathways (p53, PI3K-Akt, autophagy, and transcription dysregulation in cancer) were identified to play critical roles in distinguishing HPV-positive OPSCC from HPV-negative OPSCC.

Abstract
Human papillomavirus (HPV) is an etiological risk factor for oropharyngeal squamous cell carcinomas (OPSCC). Our study investigates the prevalence, prognostic, and clinicopathologic features of HPV-related oropharyngeal cancer in Northeast China and elucidates the involvement of p16 in the tumorigenesis and progression of OPSCC. Specimens from 1470 OPSCC patients collected from 2000 to 2016 were analyzed using the status of HPV by polymerase chain reaction (PCR) and p16 immunohistochemistry. Overexpression of p16 was observed in 81 (5.51%) of the 1470 cases, and HPV positive was present in 78 cases (5.31%) of the 1470 cases. HPV positive and p16 overexpression have a good concordance. However, we found that the etiological fraction of HPV in cancers of the OPSCCs was obviously lower in Northeast China than other cohorts previously reported. Interestingly, nearly 89% of patients with p16 expression were smokers, and nearly 70% of patients with p16 expression had a history of alcohol. Our study also demonstrates that p16 expression is significantly associated with early stage primary OPSCCs and the patients with p16 expression tend to show better survival following surgery and radiotherapy.

Abstract
Context Human papillomavirus (HPV) is a major cause of oropharyngeal squamous cell carcinomas, and HPV (and/or surrogate marker p16) status has emerged as a prognostic marker that significantly impacts clinical management. There is no current consensus on when to test oropharyngeal squamous cell carcinomas for HPV/p16 or on which tests to choose. Objective To develop evidence-based recommendations for the testing, application, interpretation, and reporting of HPV and surrogate marker tests in head and neck carcinomas. Design The College of American Pathologists convened a panel of experts in head and neck and molecular pathology, as well as surgical, medical, and radiation oncology, to develop recommendations. A systematic review of the literature was conducted to address 6 key questions. Final recommendations were derived from strength of evidence, open comment period feedback, and expert panel consensus. Results The major recommendations include (1) testing newly diagnosed oropharyngeal squamous cell carcinoma patients for high-risk HPV, either from the primary tumor or from cervical nodal metastases, using p16 immunohistochemistry with a 70% nuclear and cytoplasmic staining cutoff, and (2) not routinely testing nonsquamous oropharyngeal carcinomas or nonoropharyngeal carcinomas for HPV. Pathologists are to report tumors as HPV positive or p16 positive. Guidelines are provided for testing cytologic samples and handling of locoregional and distant recurrence specimens. Conclusions Based on the systematic review and on expert panel consensus, high-risk HPV testing is recommended for all new oropharyngeal squamous cell carcinoma patients, but not routinely recommended for other head and neck carcinomas.

Abstract
OBJECTIVES/HYPOTHESIS This study aimed to analyze the effect of human papillomavirus (HPV)-associated T1-2 node-positive oropharyngeal squamous cell carcinoma (OPSCC) on nodal response, recurrent disease, and survival in patients treated according to the Rotterdam protocol. STUDY DESIGN Retrospective cohort study. METHODS In total, 77 patients with T1-2 OPSCC with nodal disease, treated between 2000 and 2012, were included in this study. Patients were treated according to the Rotterdam protocol: 46 Gy of IMRT followed by a local boost using cyberknife or brachytherapy (22 Gy) and neck dissection. The presence of HPV was determined by p16INK4A immunostaining. Outcomes were overall survival, disease-free survival, and the extent of nodal response. Nodal stage was determined following the 7th and 8th American Joint Cancer Committee/Union for International Cancer Control classification. RESULTS Overall, 68.4% of patients had p16-positive disease, and 35.4% of all patients achieved complete nodal response (pN0) after 46 Gy of intensity-modulated radiotherapy (IMRT). Based on the 7th TNM classification, nodal response (partial or complete) was significantly associated with HPV status (P = .002). Patients with p16-positive OPSCC had an odds ratio (OR) of 4.6 to achieve complete nodal response. However, smoking interacted with this effect. Applying the 8th TNM classification, complete or partial response was associated with HPV status but was not significant (OR: 1.7, P = .138). Complete nodal response led to 100% overall survival in p16-positive OPSCC patients. CONCLUSIONS HPV-related OPSCCs are associated with complete nodal response after 46 Gy of IMRT. Patients with full regional control (pN0) after IMRT and subsequent neck dissection show a significantly better overall survival, but smoking negatively interacts with this effect.

Abstract
High-risk human papillomavirus (HPV) is a major risk factor for oral and pharyngeal cancers (OPCs), yet the detailed mechanisms by which HPV promotes OPCs are not understood. Forkhead box M1B (FoxM1B) is an oncogene essential for cell cycle progression and tumorigenesis, and it is aberrantly overexpressed in many tumors. We previously showed that FoxM1B was the putative target of an epithelial-specific transcription factor, Grainyhead-like 2 (GRHL2). In the current study, we demonstrate that HPV type 16 (HPV-16) E6 induces FoxM1B in human oral keratinocytes (HOKs) and tonsillar epithelial cells (TECs) in part through GRHL2. FoxM1B was barely detectable in cultured normal human oral keratinocytes (NHOKs) and progressively increased in immortalized HOKs harboring HPV-16 genome (HOK-16B) and tumorigenic HOK-16B/BaP-T cells. Retroviral expression of HPV-16 E6 and/or E7 in NHOKs, TECs, and hypopharyngeal carcinoma cells (FaDu) revealed induction of FoxM1B and GRHL2 by the E6 protein but not E7. Both GRHL2 and FoxM1B were strongly induced in the epidermis of HPV-16 E6 transgenic mice and HPV+ oral squamous cell carcinomas. Ectopic expression of FoxM1B led to acquisition of transformed phenotype in HOK-16B cells. Loss of FoxM1B by lentiviral short hairpin RNA vector or chemical inhibitor led to elimination of tumorigenic characteristics of HOK-16B/BaP-T cells. Luciferase reporter assay revealed that GRHL2 directly bound and regulated the FoxM1B gene promoter activity. Using epithelial-specific Grhl2 conditional knockout mice, we exposed wild-type (WT) and Grhl2 KO mice to 4-nitroquinolin 1-oxide (4-NQO), which led to induction of FoxM1B in the tongue tissues and rampant oral tumor development in the WT mice. However, 4-NQO exposure failed to induce tongue tumors or induction of FoxM1B expression in Grhl2 KO mice. Collectively, these results indicate that HPV-16 induces FoxM1B in part through GRHL2 transcriptional activity and that elevated FoxM1B level is required for oropharyngeal cancer development.

Abstract
PURPOSE OF REVIEW In head and neck cancer management, immunoexpression of protein p16 is widely used as a surrogate marker for human papillomavirus (HPV) positivity due to challenges of direct HPV testing. Previously p16 has been reported to have good sensitivity but only moderate specificity in HPV-status determination. The aim of this review is to evaluate the existing information on sensitivity and specificity of p16 immunohistochemistry (IHC) in HPV-status determination among the recent studies. RECENT FINDINGS We searched the time period from October 2014 to April 2016 and included 28 studies (a total of 31 analyses), which reported both p16 and HPV status in their series. The sensitivity of p16 in HPV determination ranged between 28.2 and 100.0%. The mean and median sensitivities were 90.5 and 95.4%, respectively. The specificity ranged between 31.1 and 100.0%. The mean and median specificities were 83.3 and 87.3%, respectively. SUMMARY Our review presents current information on the feasibility of p16 IHC in HPV status determination, which is in line with previous studies. Patients with HPV-positive tumors can be identified with p16 IHC, but a risk for misclassification of HPV-negative tumors as HPV positive exists. This fact has to be taken into consideration if HPV status will influence treatment planning.

Prevalence and types of high-risk human papillomaviruses in head and neck cancers from Bangladesh. BMC Cancer 2017; 17:792.

Abstract
BACKGROUND There is a dramatic rise in the incidence of Human papillomavirus (HPV) - associated head and neck squamous cell carcinoma (HNSCC) in the world, with considerable variation by geography, gender and ethnicity. Little is known about the situation in Bangladesh, where tobacco- and areca nut-related head and neck cancers (HNCs) are the most common cancers in men. We aimed to determine the prevalence of HPV in HNSCC in Bangladesh and to explore the possible value of cell cycle markers in clinical diagnostic settings. METHODS One hundred and ninety six archival HNSCC tissue samples were analysed for the presence of HPV DNA. The DNA quality was assured, and then amplified using a nested PCR approach. The typing of HPV was performed by automated DNA sequencing. Cellular markers p53, Cyclin D1 and pRb were tested on all samples by immunohistochemistry (IHC), as well as p16 as a putative surrogate for the detection of HPV. RESULTS HPV DNA was detected in 36/174 (~21%) samples: 36% of cancers from the oropharynx; 31% of oral cancers, and 22% from the larynx. HPV-16 was most common, being present in 33 samples, followed by HPV-33 (2 samples) and HPV-31 (1 sample). Twenty-eight out of 174 samples were positive for p16, predominantly in HPV-positive tissues (p < 0.001). No statistically significant association was observed between the cellular markers and HPV DNA positive cases. However, p16 positivity had excellent predictive value for the presence of HPV by PCR. CONCLUSION There is a significant burden of HPV-associated HNSCC in Bangladesh, particularly in the oropharynx but also in oral and laryngeal cancers. Whilst a combination of PCR-based DNA detection and p16 IHC is useful, the latter has excellent specificity, acceptable sensitivity and good predictive value for carriage of HPV in this population and should be used for prognostic evaluation and treatment planning of all HNSCC patients in South Asia, as in the Western world.

Abstract
BACKGROUND The incidence of oropharyngeal cancer has risen over the past 2 decades. This rise has been attributed to human papillomavirus (HPV), but information on temporal trends in incidence of HPV-associated cancers across Canada is limited. METHODS We collected social, clinical and demographic characteristics and p16 protein status (p16-positive or p16-negative, using this immunohistochemistry variable as a surrogate marker of HPV status) for 3643 patients with oropharyngeal cancer diagnosed between 2000 and 2012 at comprehensive cancer centres in British Columbia (6 centres), Edmonton, Calgary, Toronto and Halifax. We used receiver operating characteristic curves and multiple imputation to estimate the p16 status for missing values. We chose a best-imputation probability cut point on the basis of accuracy in samples with known p16 status and through an independent relation between p16 status and overall survival. We used logistic and Cox proportional hazard regression. RESULTS We found no temporal changes in p16-positive status initially, but there was significant selection bias, with p16 testing significantly more likely to be performed in males, lifetime never-smokers, patients with tonsillar or base-of-tongue tumours and those with nodal involvement (p < 0.05 for each variable). We used the following variables associated with p16-positive status for multiple imputation: male sex, tonsillar or base-of-tongue tumours, smaller tumours, nodal involvement, less smoking and lower alcohol consumption (p < 0.05 for each variable). Using sensitivity analyses, we showed that different imputation probability cut points for p16-positive status each identified a rise from 2000 to 2012, with the best-probability cut point identifying an increase from 47.3% in 2000 to 73.7% in 2012 (p < 0.001). INTERPRETATION Across multiple centres in Canada, there was a steady rise in the proportion of oropharyngeal cancers attributable to HPV from 2000 to 2012.

Abstract
Geminin is a protein involved in cell cycle progression. We aimed to evaluate the diagnostic value of geminin expression in cervical intraepithelial neoplasm (CIN).The expression of geminin, p16, and Ki67 was examined in 95 samples, including CIN1 (n = 45), CIN2/3 (n = 40), and normal cervical tissues (n = 10) by immunohistochemistry. The correlation between geminin or p16 expression and human papillomavirus (HPV) status was also evaluated.Geminin expression was negative in all normal tissues and expressed in 13.3% of CIN1 and 90.0% of CIN2/3. P16 expression was demonstrated in 24.4% of CIN1 and 87.5% of CIN2/3. The corresponding Ki67 expression was 35.6% and 95.0%. The specificity of geminin for differentiating between CIN1 and CIN2/3 was 86.7%, while for p16 and Ki67 the corresponding values were 75.6% and 64.4%. The sensitivity of geminin, p16, and Ki67 was 90.0%, 87.5%, and 95.0%, respectively. The positive predictive value (PPV) and accuracy of geminin were higher than p16 and Ki67. In addition, geminin expression showed a weak correlation with HPV status, but there was no association between p16 expression and HPV status.These results suggested that geminin had a high degree of sensitivity and specificity in determining CIN2/3. In addition to p16 and Ki67, geminin might be used as a new biomarker to distinguish between CIN1 and CIN2/3.

Abstract
GOAL: To investigate the HPV prevalence and characterize the expression of potential molecular surrogate markers of HPV infection in esophageal squamous cell carcinoma. MATERIALS AND METHODS: The prevalence of HPV in individuals with and without esophageal cancer (EC) was determined by using multiplex PCR; p16 and p53 protein levels were assessed by immunohistochemistry (IHC). RESULTS: High-risk HPV (hr-HPV) was found in the same frequency (13.8%) in esophageal squamous cell carcinoma (ESCC) and in healthy individuals. The p53 expression was positive in 67.5% of tumor tissue, 20.0% of adjacent non-tumoral tissue and 1.8% of normal esophageal tissue. p16 was positive in 11.6% of esophageal cancer cases and 4.7% of adjacent non-tumoral tissue. p16 was undetectable among control group samples. p53 and p16 levels were not significantly associated with the HPV status. CONCLUSIONS: These results suggest that hr-HPV types are not associated with the development of ESCC and that p53 and p16 protein expression have no relationship with HPV infection in normal or cancerous esophagus.

Abstract
Oropharyngeal squamous cell carcinomas (OPSCC) are common, have poor outcomes, and comprise two biologically and clinically distinct diseases. While OPSCC that arise from human papillomavirus infections (HPV+) have better overall survival than their HPV- counterparts, the incidence of HPV+ OPSCC is increasing dramatically, affecting younger individuals which are often left with life-long co-morbidities from aggressive treatment. To identify patients which do poorly versus those who might benefit from milder regimens, risk-stratifying biomarkers are now needed within this population. One potential marker is the DEK oncoprotein, whose transcriptional upregulation in most malignancies is associated with chemotherapy resistance, advanced tumor stage, and worse outcomes. Herein, a retrospective case study was performed on DEK protein expression in therapy-naïve surgical resections from 194 OPSCC patients. We found that DEK was associated with advanced tumor stage, increased hazard of death, and interleukin IL6 expression in HPV16+ disease. Surprisingly, DEK levels in HPV16- OPSCC were not associated with advanced tumor stage or increased hazard of death. Overall, these findings mark HPV16- OPSCC as an exceptional malignancy were DEK expression does not correlate with outcome, and support the potential prognostic utility of DEK to identify aggressive HPV16+ disease.

Abstract
Laboratory tests have a key role in preventing human papillomavirus (HPV)-driven carcinomas and in guiding therapeutic interventions. An understanding of the virology, immunology, and carcinogenesis of HPV is essential for choosing appropriate diagnostic test modalities and developing new and even more effective cancer prevention strategies. HPV infects basal epithelial cells on multiple surfaces and induces carcinoma primarily in the cervix and the oropharynx. HPV types are stratified as high risk or low risk based on their carcinogenic potential. During oncogenesis, HPV interferes with cell cycle regulation and incites DNA damage responses that thwart apoptosis and enable mutations to accumulate. Such mutations are an adverse effect of innate and adaptive antiviral immune responses that up-regulate DNA-editing enzymes, with natural selection of cells having a chromosomally integrated viral genome lacking expression of viral proteins targeted by the immune system. Infected cancers share a similar mutation signature, reflecting the effect of apolipoprotein B mRNA-editing catalytic polypeptide enzyme DNA-editing enzymes. It is feasible that genomic tests for characteristic mutations or methylation signatures, along with tests for dysregulated HPV gene expression, add value in predicting behavior of premalignant lesions. Furthermore, these tumor markers in cell-free DNA of plasma or body fluids may one day assist in early detection or monitoring cancer burden during treatment.

Abstract
Much of the current literature regarding the molecular pathophysiology of human papillomavirus (HPV) in head and neck squamous cell carcinoma (HNSCC) has focused on the virus's effect on cell cycle modulation and cell proliferation. A second mechanism of pathogenicity employed by HPV, dysregulation of cellular DNA repair processes, has been more sparsely studied. The purpose of this review is to describe current understanding about the effect of HPV on DNA repair in HNSCC, taking cues from cervical cancer literature. HPV affects DNA-damage response pathways by interacting with many proteins, including ATM, ATR, MRN, γ-H2AX, Chk1, Chk2, p53, BRCA1, BRCA2, RAD51, Rb-related proteins 107 and 130, Tip60, and p16INK4A. Further elucidation of these pathways could lead to development of targeted therapies and improvement of current treatment protocols.

Abstract
Available clinical human papilloma virus (HPV) diagnostics for head and neck cancer have limited sensitivity and/or fail to define the HPV genotype. Common HPV genotyping assays are costly and labor intensive. We sought to develop a next-generation sequencing (NGS)-based HPV genotyping assay that was sensitive enough to work on formalin-fixed paraffin-embedded (FFPE) samples. We developed an ion torrent NGS HPV genotyping assay using barcoded HPV PCR broad-spectrum general primers 5(+)/6(+) (BSGP)5(+)/6(+). To validate genotype specificity and use in archived clinical FFPE tumor samples, we compared NGS HPV genotyping at 2 sequencing centers with typing by Roche Linear Array assay in 42 oropharyngeal and cervical cancer specimens representing 10 HPV genotypes, as well as HPV-negative cases. To demonstrate the detection of a broad range of HPV genotypes, we genotyped a cohort of 266 cervical cancers. A comparison of NGS genotyping of FFPE cancer specimens with genotyping by Linear Array showed concordant results in 34/37 samples (92%) at sequencing site 1 and 39/42 samples (93%) at sequencing site 2. Concordance between sites was 92%. Designed for use with 10 ng genomic DNA, the assay detected HPV using as little as 1.25 ng FFPE-derived genomic DNA. In 266 cervical cancer specimens, the NGS assay identified 20 different HPV genotypes, including all 13 carcinogenic genotypes. This novel NGS assay provides a sensitive and specific high-throughput method to detect and genotype HPV in a range of clinical specimens derived from FFPE with low per-sample cost.

Abstract
BACKGROUND We aimed to study the prevalence of oral sex and its possible association with human papillomavirus (HPV) 16 infection in the development of oropharyngeal cancer in the US population for possible prevention. METHODS We conduct a systemic review on the prevalence of oral sex among Americans among different age groups, the prevalence of HPV 16 infection reported in oropharyngeal cancer, and correlation between oral sex and oropharyngeal cancer. RESULTS Oral sex is prevalent among adolescents and sexually active adults. Sixty percent of oropharyngeal cancer reported in the United States is associated with HPV 16 infections. Individuals who practiced oral sex with multiple partners are at risk for developing oropharyngeal cancer and need to be informed about practicing safe sex or getting vaccination. CONCLUSION Family physicians will play a key role in prevention and educating the public about the risk of oral sex.

Genes identified were evaluated for their association with survival on the basis of univariable and multivariable Cox proportional hazards models. RESULTS Three genes were found to be associated with poor prognosis. The most significant association was seen with spectrin expression. Subjects whose tumors expressed spectrin were 4.60 times more likely (hazard ratio; 95% confidence interval: 1.88-11.25) to die at any given time when compared with those without spectrin (P = .001). On univariable analysis, subjects with late-stage cancer were 6.34 times more likely (hazard ratio; 95% confidence interval: 1.41-28.53; P = .02) to die at any given time, but interestingly, after controlling for spectrin, this effect was attenuated (P = .07). Despite controlling for several possible confounding effects, the effect of spectrin remained hazardous throughout all multivariable models. This was true even after controlling for cancer stage and extracapsular extension (P = .004). CONCLUSION Our analysis of public genomic data shows promise in identifying biomarkers that may allow clinicians to make more accurate survival predictions. Spectrin is a strong candidate for further biomarker testing.

p53 expression but not p16(INK4A) correlates with human papillomavirus-associated esophageal squamous cell carcinoma in Kazakh population. Infect Agent Cancer 2016; 11:19. [PMID: 27076841 PMCID: PMC4830030 DOI: 10.1186/s13027-016-0065-x] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2016] [Accepted: 03/15/2016] [Indexed: 12/20/2022] Open
Abstract
Background p16INK4A expression has been used as a surrogate marker for human papillomavirus (HPV) infection in cervical cancer and head and neck cancer. p53 has also been reported as a feasible marker to identify HPV-positive oropharyngeal carcinoma and penile lesions. This study aimed to investigate p16INK4A and p53 expression levels and their correlation with HPV status and clinical parameters in Kazakh patients with esophageal squamous cell carcinoma. Methods Immunohistochemical expression of p16INK4A and p53 were evaluated in 163 cases of esophageal squamous cell carcinoma in Kazakh patients. The presence of HPV DNA was detected by polymerase chain reaction. Results p16INK4A-positive expression was detected in 19.0 % of patients, and its expression was significantly correlated with a lower frequency of lymph node metastasis (p = 0.038). By contrast no significant association was found between p16INK4A-positive expression and HPV status (correlation coefficient = -0.062, p = 0.499). p16INK4A-positive expression did not affect the odds of tumors being HPV positive (odds ratio [OR] = 0.727 with 95 % confidence interval [CI] = 0.288–1.836). The sensitivity of p16INK4A-positive expression as an HPV marker was 0.164, with a specificity of 0.788 and a positive predictive value of 0.391. p53-positive expression was present in 88.3 % of all cases. Although no significant correlation with available clinical parameters was found, a significantly inverse correlation was observed between p53 expression and HPV status (correlation coefficient = -0.186, p = 0.039). Moreover, p53-positive expression decreased the odds of tumors being HPV positive (OR = 0.292 with 95 % CI = 0.086–0.990). The sensitivity of p53-negative expression as an HPV marker was 0.179, with a specificity of 0.940 and a positive predictive value of 0.714. The overall HPV prevalence was high (45.5 %) in Kazakh patients, with no significant association between HPV positivity and available clinical parameters or combined p16INK4A/p53 expression. Conclusions p16INK4A-positive expression was associated with lymph node metastasis. Results indicate that p53-negative expression and not p16INK4A-positive expression may be used as a marker for HPV status in ESCC; however, this finding requires further studies for validation.

Development and validation of a staging system for HPV-related oropharyngeal cancer by the International Collaboration on Oropharyngeal cancer Network for Staging (ICON-S): a multicentre cohort study. Lancet Oncol 2016; 17:440-451. [PMID: 26936027 DOI: 10.1016/s1470-2045(15)00560-4] [Citation(s) in RCA: 488] [Impact Index Per Article: 61.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2015] [Revised: 11/27/2015] [Accepted: 11/27/2015] [Indexed: 10/22/2022]
Abstract
BACKGROUND Human papillomavirus-related (HPV+) oropharyngeal cancer is a rapidly emerging disease with generally good prognosis. Many prognostic algorithms for oropharyngeal cancer incorporate HPV status as a stratification factor, rather than recognising the uniqueness of HPV+ disease. The International Collaboration on Oropharyngeal cancer Network for Staging (ICON-S) aimed to develop a TNM classification specific to HPV+ oropharyngeal cancer. METHODS The ICON-S study included patients with non-metastatic oropharyngeal cancer from seven cancer centres located across Europe and North America; one centre comprised the training cohort and six formed the validation cohorts. We ascertained patients' HPV status with p16 staining or in-situ hybridisation. We compared overall survival at 5 years between training and validation cohorts according to 7th edition TNM classifications and HPV status. We used recursive partitioning analysis (RPA) and adjusted hazard ratio (AHR) modelling methods to derive new staging classifications for HPV+ oropharyngeal cancer. Recent hypotheses concerning the effect of lower neck lymph nodes and number of lymph nodes were also investigated in an exploratory training cohort to assess relevance within the ICON-S classification. FINDINGS Of 1907 patients with HPV+ oropharyngeal cancer, 661 (35%) were recruited at the training centre and 1246 (65%) were enrolled at the validation centres. 5-year overall survival was similar for 7th edition TNM stage I, II, III, and IVA (respectively; 88% [95% CI 74-100]; 82% [71-95]; 84% [79-89]; and 81% [79-83]; global p=0·25) but was lower for stage IVB (60% [53-68]; p<0·0001). 5-year overall survival did not differ among N0 (80% [95% CI 73-87]), N1-N2a (87% [83-90]), and N2b (83% [80-86]) subsets, but was significantly lower for those with N3 disease (59% [51-69]; p<0·0001). Stage classifications derived by RPA and AHR models were ranked according to survival performance, and AHR-New was ranked first, followed by AHR-Orig, RPA, and 7th edition TNM. AHR-New was selected as the proposed ICON-S stage classification. Because 5-year overall survival was similar for patients classed as T4a and T4b, T4 is no longer subdivided in the re-termed ICON-S T categories. Since 5-year overall survival was similar among N1, N2a, and N2b, we re-termed the 7th edition N categories as follows: ICON-S N0, no lymph nodes; ICON-S N1, ipsilateral lymph nodes; ICON-S N2, bilateral or contralateral lymph nodes; and ICON-S N3, lymph nodes larger than 6 cm. This resembles the N classification of nasopharyngeal carcinoma but without a lower neck lymph node variable. The proposed ICON-S classification is stage I (T1-T2N0-N1), stage II (T1-T2N2 or T3N0-N2), and stage III (T4 or N3). Metastatic disease (M1) is classified as ICON-S stage IV. In an exploratory training cohort (n=702), lower lymph node neck involvement had a significant effect on survival in ICON-S stage III but had no effect in ICON-S stage I and II and was not significant as an independent factor. Overall survival was similar for patients with fewer than five lymph nodes and those with five or more lymph nodes, within all ICON-S stages. INTERPRETATION Our proposed ICON-S staging system for HPV+ oropharyngeal cancer is suitable for the 8th edition of the Union for International Cancer Control/American Joint Committee on Cancer TNM classification. Future work is needed to ascertain whether T and N categories should be further refined and whether non-anatomical factors might augment the full classification. FUNDING None.

Sedghizadeh PP, Billington WD, Paxton D, Ebeed R, Mahabady S, Clark GT, Enciso R. Is p16-positive oropharyngeal squamous cell carcinoma associated with favorable prognosis? A systematic review and meta-analysis. Oral Oncol 2016; 54:15-27. [PMID: 26794879 DOI: 10.1016/j.oraloncology.2016.01.002] [Citation(s) in RCA: 58] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2015] [Revised: 11/30/2015] [Accepted: 01/01/2016] [Indexed: 12/29/2022]
Abstract
The purpose of this systematic review and meta-analysis was to compare the prognosis of patients with p16 expressing oropharyngeal squamous cell cancers to patients with p16 non-expressing cancers. Clinical outcomes that were evaluated included overall survival, local recurrence, disease-free survival, disease-specific survival, and event-free survival. The following electronic databases were searched: Cochrane Library, MEDLINE (via Pubmed), and Web of Science. Publications were restricted to English language. Studies were limited to controlled clinical trials on the survival rates of patients with oropharyngeal tumors that were p16 expressing, compared to patients with p16 non-expressing tumors, and at least one clinical endpoint reported by trial authors (hazard ratios). Specific ascertainment criteria were applied for inclusion and exclusion of eligible studies. Data was independently extracted in duplicate. This systematic review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analysis PRISMA checklist. Risk of bias was assessed for all included studies, and disagreements between review authors were discussed until an agreement was reached. Eighteen studies were included for final review and meta-analysis. The subgroup meta-analyses, which included survival and recurrence data, showed significantly favorable outcomes for patients with p16 expressing tumors. There is strong evidence to support that patients with p16 expressing oropharyngeal squamous cell cancers have favorable clinical outcomes and prognosis.
