Abstract

BACKGROUND:

There is increasing evidence that high-risk human papillomavirus plays significant role in oropharyngeal cancer; however, there is lack of knowledge on the interplay between the virus and its downstream related molecules and their possible prognostic values. The objectives of the study are to better understand the interplay of the HR-HPV and its associated downstream molecules and to evaluate potential biomarkers for patient outcomes.

METHODS:

We conducted a retrospective study with available formalin-fixed, paraffin-embedded tissue from 244 oropharyngeal cancer patients that received curative radiotherapy or concurrent chemoradiotherapy from 2000 to 2008. In addition to chart review, we performed HPV DNA and RNA in situ hybridization and immunohistochemistry for p53, the retinoblastoma protein, p16, and cyclin D1 analysis. Cox-proportional hazard and Kaplan-Meier survival analysis were used to determine the prognostic markers for clinical outcomes.

RESULTS:

Patients averaged 57.3±9.4 year-old and were mostly males (76.2%) and ever-smokers (76.2%). All patients received curative radiotherapy and 44.3% received concurrent chemoradiotherapy. We detected the human papillomavirus in 77.9% of study patients. Ever-smokers, more advanced tumor stage, and receiving radiotherapy only had poorer 5-year overall survival, disease-specific survival, and loco-regional recurrence. Cases with positive human papillomavirus and p53 overexpression had poorer disease-specific survival. Cases without human papillomavirus, but cyclin D1 overexpression, was associated with poorer 5-year overall survival.

CONCLUSIONS:

Our data suggests that additional p53 and cyclin D1 testing may benefit oropharyngeal cancer patients with known human papillomavirus status.

The aim of this study is comparing two in situ hybridization (ISH) detection methods for human papilloma virus (HPV) 16 E6/E7 mRNA, i.e. the RNAscope™ 2.0 High Definition (HD) and the upgraded RNAscope™ 2.5 HD version. The RNAscope™ 2.5 HD has recently replaced the RNAscope™ 2.0 HD detection kit. Therefore, this investigation starts from the need to analytically validate the new mRNA ISH assay and, possibly, to refine the current algorithm for HPV detection in oropharyngeal squamous cell carcinoma (OSCC) with the final goal to apply it to daily laboratory practice. The study was based on HPV status and on generated data, interpreted by a scoring algorithm. The results highlighted that the compared RNAscope HPV tests had a good level of interchangeability and enabled to identify OSCC that are truly driven by high risk-HPV infection. This was also supported by the comparison of the RNAscope HPV test with HPV E6/E7 mRNA real time reverse transcriptase-polymerase chain reaction (RT-PCR), in a fraction of cases where material for HPV E6/E7 mRNA real time RT-PCR was available. Furthermore, the algorithm that associates p16 immunohistochemistry (IHC) with the identification of HPV mRNA by RNAscope was more effective than the one that associated p16 IHC with the identification of HPV DNA by ISH.

Abstract: Background: The recognition of tumor infection by human papilloma virus (HPV) in oropharyngeal squamous-cell carcinoma (OSCC) is emerging as a valid biomarker to more accurate selection of patients for specific treatment, surveillance and tumor staging. To this aim, the HPV detection strategy in OSCC must dissect between HPV that is acting as a driver of malignant transformation, and transcriptionally silent virus involved in productive infection. The aim of this study is to define the better method for the accurate identification of HPV status among OSCC. Patients and Methods: Thirty-six patients were selected for HPV status assessment combining different methods, such as immunohistochemistry (IHC) for p16, in-situ hybridization (ISH) for high risk (HR)-HPV DNA and HR-HPV E6/E7 mRNA along with real-time PCR of HPV16 E6/E7 mRNA. All these cases were originally classified as HPV negative by DNA-based ISH but p16 positive by the IHC. Results: Twenty-six cases showed concordance between methods; whereas, nine cases resulted negative for HPV E6/E7 mRNA RT-PCR but positive for HPV E6/E7 mRNA ISH. Conclusion: By considering that the bright field HPV E6/E7 mRNA ISH could be more sensitive than mRNA-based real-time RT-PCR, and that it provides the precise identification of transcriptionally active HPV infected cells, a randomized analysis to validate the robustness of this preliminary assay will be undertaken.

Epidermodysplasia verruciformis (EDV) is a rare genodermatosis that predisposes individuals to persistent infection with β-human papillomavirus (HPV) genotypes. The term EDV acanthoma may be applied to lesions with incidental findings of EDV-defining histopathological features without clinical signs of EDV. We report a case of HPV-14- and -21-positive EDV acanthoma arising in association with condyloma in a female patient with a history of low-grade squamous intraepithelial lesion of the cervix positive for high-risk HPV (non-16/18), chronic kidney disease, and systemic lupus erythematosus. The patient had no family or personal history of EDV, but the patient was on immunosuppressive therapy with mycophenolate mofetil and prednisone. A biopsy specimen from one of the perianal lesions revealed histopathologic changes consistent with EDV in the setting of condyloma. Molecular testing showed HPV-14 and -21, which supported the coexistence of condyloma with EDV acanthoma.

HPV-related multiphenotypic sinonasal carcinoma (HMSC) is associated with high-risk human papillomavirus (HR-HPV) infection. Using HR-HPV mRNA in situ hybridization (ISH), we reported six new HMSC cases and compared their histopathology with that of sinonasal adenoid cystic carcinoma (ACC). Using p16 immunohistochemistry (IHC) and HR-HPV ISH, we retrospectively identified six HMSC cases. All HMSC cases were positive for HR-HPV mRNA ISH and p16 IHC. Two HMSC cases had overlying atypical squamous epithelium and one also had invasive squamous cell carcinoma (SCC). All HMSC were SOX10-positive whereas the overlying atypical squamous epithelium and the SCC were SOX10-negative. One atypical HMSC-like case was also identified which was positive for HR-HPV mRNA ISH, HR-HPV DNA ISH, SOX10 IHC, but negative for p16 IHC. This study showed that HR-HPV mRNA ISH was a useful tool to diagnose HMSC and had stronger signals than HR-HPV DNA ISH. HR-HPV E6/E7 mRNA could be identified in the overlying atypical squamous epithelium as well as the invasive SCC. A combination of p16 and SOX10 IHC will be a useful screening panel for HMSC followed by confirmatory HR-HPV mRNA ISH test.

We investigated the role of high-risk human papillomavirus (hr-HPV) in patients with Barrett's dysplasia and adenocarcinoma (EAC). Clearance vs persistence of HPV (DNA, E6 or E7 mRNA, and p16INK4A protein) and overexpression or mutation of p53 were determined for 40 patients who underwent endotherapy for Barrett's dysplasia or EAC. After ablation, dysplasia or neoplasia was eradicated in 34 subjects (24 squamous, 10 intestinal metaplasia). Six patients had detectable lesions after treatment; 2 were positive for transcriptionally active hr-HPV, and 4 had overexpression of p53. Before endotherapy, 15 patients had biologically active hr-HPV, 13 cleared the infection with treatment, and dysplasia or EAC was eliminated from 12 patients. One patient who cleared HPV after ablation acquired a p53 mutation, and their cancer progressed. Of 13 patients with overexpression of p53 before treatment, 10 cleared the p53 abnormality after ablation with eradication of dysplasia or neoplasia, whereas 3 of 13 had persistent p53 mutation-associated dysplasia after endotherapy (P = .004). Immunohistochemical and sequence analyses of p53 produced concordant results for 36 of 40 samples (90%). Detection of dysplasia or neoplasia after treatment was associated with HPV persistence or continued p53 overexpression.

Oropharyngeal squamous cell carcinoma is frequently associated with high-risk HPV infection, which confers a good prognosis. Immunohistochemistry for p16 is used as a surrogate for HPV status, but discrepant results are occasionally seen. Here, we report a case with a unique pattern of partial loss of p16.A 63 year old male presented with a base of tongue nonkeratinizing squamous cell carcinoma and a large metastatic neck mass. The primary lesion and multiple regions of the metastatic mass were assessed with p16 immunohistochemistry, RNA in situ hybridization for high-risk HPV, and HPV16 genome sequencing.The primary lesion was p16 negative, and the metastatic neck mass had large, confluent regions that were either strongly p16 positive or entirely p16 negative. All of these regions were positive for high-risk HPV with identical HPV16 genomes.This unusual case illustrates a potential diagnostic pitfall, and it raises important questions regarding molecular mechanisms and prognostic implications of p16 staining in oropharyngeal squamous cell carcinoma.

Molecular Analysis of HPV-independent Primary Endometrial Squamous Cell Carcinoma Reveals TP53 and CDKN2A comutations: A Clinicopathologic Analysis With Re-evaluation of Diagnostic Criteria

Human papillomavirus (HPV)-independent primary endometrial squamous cell carcinoma (PESCC) is a rare but aggressive subtype of endometrial carcinoma for which little is known about the genomic characteristics. Traditional criteria have restricted the diagnosis of PESCC to cases without any cervical involvement. However, given that modern ancillary techniques can detect HPV and characteristic genetic alterations that should identify the more common mimics in the differential diagnosis, including endometrial endometrioid carcinoma with extensive squamous differentiation and HPV-associated primary cervical squamous cell carcinoma, those criteria may benefit from revision. To further characterize PESCC, we identified 5 cases of pure squamous cell carcinoma dominantly involving the endometrium that had the potential to be PESCC: 1 case involving only the endometrium and 4 cases with some involvement of the cervix. Clinicopathologic features were assessed and immunohistochemical analysis (p16, estrogen receptor, progesterone receptor, and p53), HPV RNA in situ hybridization (high-risk and low-risk cocktails and targeted probes for 16 and 18), and molecular studies were performed. All tumors showed aberrant/mutation-type p53 expression, were negative for estrogen receptor, progesterone receptor, and p16, and had no detectable HPV. Per whole-exome sequencing, 4 of the 5 tumors demonstrated comutations in TP53 and CDKN2A (p16). Four patients died of disease within 20 months (range, 1 to 20 mo; mean, 9 mo), and 1 patient had no evidence of disease at 38 months. PESCC represents a unique, clinically aggressive subtype of endometrial cancer with TP53 and CDKN2A comutations. This characteristic profile, which is similar to HPV-independent squamous cell carcinoma of the vulva, is distinct from endometrioid carcinoma with extensive squamous differentiation and HPV-associated primary cervical squamous cell carcinoma and can be used to distinguish PESCC from those mimics even when cervical involvement is present. Diagnostic criteria for PESCC should be relaxed to allow for cervical involvement when other pathologic features are consistent with, and ancillary techniques are supportive of classification as such.

Abstract

IMPORTANCE:

Human papillomavirus (HPV) causes an increasing proportion of oropharyngeal squamous cell carcinomas (OPSCCs), particularly in white men. The prevalence of HPV among other demographic groups and other anatomic sites of HNSCC is unclear.

OBJECTIVE:

To explore the role of HPV tumor status among women and nonwhites with OPSCC and patients with nonoropharyngeal head and neck squamous cell carcinoma (non-OP HNSCC).

DESIGN, SETTING, AND PARTICIPANTS:

Retrospective cohort study at 2 tertiary academic centers including cases diagnosed 1995 through 2012, oversampled for minorities and females. A stratified random sample of 863 patients with newly diagnosed SCC of the oral cavity, oropharynx, larynx, or nasopharynx was used.

MAIN OUTCOMES AND MEASURES:

Outcomes were HPV status as measured by p16 immunohistochemical analysis, HPV16 DNA in situ hybridization (ISH), and high-risk HPV E6/E7 mRNA ISH.

RESULTS:

Of 863 patients, 551 (63.9%) were male and median age was 58 years (interquartile range, 51-68 years). Among 240 OPSCCs, 144 (60%) were p16 positive (p16+), 115 (48%) were HPV16 DNA ISH positive (ISH16+), and 134 (56%) were positive for any oncogenic HPV type (ISH+). From 1995 to 2012, the proportion of p16+ OPSCC increased significantly among women (from 29% to 77%; P = .005 for trend) and men (36% to 72%; P < .001 for trend), as well as among whites (39% to 86%; P < .001 for trend) and nonwhites (32% to 62%; P = .02 for trend). Similar results were observed for ISH+ OPSCC (P ≤ .01 for all). Among 623 non-OP HNSCCs, a higher proportion were p16+ compared with ISH positive (62 [10%] vs 30 [5%]; P = .001). A high proportion (26 of 62 [42%]) of these p16+ non-OP HNSCCs were found in sites adjacent to the oropharynx. The proportion of p16+ and ISH+ non-OP HNSCCs were similar by sex. Over time, the proportion of non-OP HNSCCs that were p16+ (or ISH+) increased among whites (P = .04 for trend) but not among nonwhites (each P > .51 for trend). Among OPSCCs, p16 had high sensitivity (100%), specificity (91%), and positive (93%) and negative predictive value (100%) for ISH positivity. In non-OP HNSCCs, p16 had lower sensitivity (83%) and positive predictive value (40%) but high specificity (94%) and negative predictive value (99%) for ISH positivity.

CONCLUSIONS AND RELEVANCE:

During 1995 through 2012, the proportion of OPSCCs caused by HPV has increased significantly. This increase was not restricted to white men but was a consistent trend for women and men, as well as for white and nonwhite racial groups. Few non-OP HNSCCs were HPV related. P16 positivity was a good surrogate for ISH+ tumor status among OPSCC, but not a good surrogate for non-OP HNSCC.

Background

Oropharyngeal cancers associated with high-risk type human papillomavirus (HR-HPV) infection have better prognosis than virus negative cancers. Similarly, the HPV status in laryngeal cancer (LC) may be associated with better outcome.

Methods

Samples from 88 patients with LC were investigated using the polymerase chain reaction (PCR) and p16 immunohistochemistry for HR-HPV analysis. The cut-off point for p16 overexpression was diffuse (≥75%) tumor expression with at least moderate (+ 2/3) staining intensity.

Results

The 5-year cumulative survival (CS) rate was 80.7% in all patients with LC. According to a combination of HR-HPV DNA status and p16 overexpression, subjects with LC were divided into four groups: HR-HPV DNA-positive/p16 overexpression-positive (n = 5, 5.7%; CS = 100%), HR-HPV DNA-positive/p16 overexpression-negative (n = 11, 12.5%; CS =81.8%), HR-HPV DNA-negative/p16 overexpression-positive (n = 0), and HR-HPV DNA-negative/p16 overexpression-negative (n = 72, 81.8%; CS = 79.5%). HR-HPV DNA-positive/p16-positive cases tended to have integrated HPV infection and high viral load, compared with HR-HPV DNA-positive/p16 overexpression-negative cases.

Conclusions

LC patients with HPV infection and high levels of p16 expression might have an improved survival outcome; however, it is necessary to recruit additional LC cases with HPV infection to determine the definitive characteristics of HPV-mediated LC and estimate survival outcome. These results may contribute to the development of a useful method for selecting patients with a potentially fair response to treatment and ensure laryngeal preservation.

Adenosquamous Carcinoma of the Head and Neck: Relationship to Human Papillomavirus and Review of the Literature.

Adenosquamous carcinoma (ADSC) of the head and neck is an aggressive variant of squamous cell carcinoma (SCC). Certain variants of head and neck SCC are human papillomavirus (HPV)-related and have better prognosis. The relationship of HPV to head and neck ADSC has not been investigated. We searched our files for the term "adenosquamous" and head and neck subsites and found cases from 1998 to 2009. The requisite histologic criteria were the presence of SCC combined with distinct gland formation and/or intracellular mucin. DNA in situ hybridization for high-risk HPV, RNA in situ hybridization for high risk HPV E6 and E7 transcripts, and immunohistochemistry for p16 and p53 were performed. The existing literature on ADSC was also reviewed. Of the 18 cases, eight were from the larynx and hypopharynx, four from the oral cavity, three from the oropharynx, and three from the nasal cavity. Three cases (16%) showed both high risk HPV E6 and E7 and p16 expression, one from the nasal cavity and two from the oropharynx. Both oropharyngeal carcinoma patients were alive and disease free at 34 and 103 months, respectively. ADSCs of the head and neck are a heterogeneous group of tumors. A small minority of cases harbor HPV and most of these, particularly those occurring at sites with known high prevalence of HPV, show active viral transcription with detectable E6 and E7 and overexpression of p16. The HPV-related oropharyngeal cases, though rare, appear to do very well clinically, while the remaining cohort of ADSC patients do quite poorly. Head and neck ADSC appears to be a mixed variant that can be further classified according to its HPV status.

Combined squamous cell carcinoma and Merkel cell carcinoma of the vulva: Role of human papillomavirus and Merkel cell polyomavirus

Merkel cell carcinoma (MCC), an uncommon and highly aggressive cutaneous malignancy, usually occurs on the sun-damaged skin of the elderly and is characterized by coexpression of neuroendocrine markers and CK20, a discriminant from other types of visceral neuroendocrine neoplasias. Since the discovery of Merkel cell polyomavirus (MCV), many researchers have confirmed its presence in about 80% of cutaneous MCCs.1 Although some cutaneous MCCs were reported to be associated with squamous cell carcinomas (SCCs), such combined cases accounted for only a minor portion and the viral status appeared to be different from pure MCC.
