Tumor-Stroma Ratio in Basaloid and Conventional Laryngeal Squamous Cell Carcinoma: Prognostic Significance and Concordance in Paired Biopsies and Surgical Samples. Cancers (Basel) 2023; 15:cancers15061645. [PMID: 36980531 PMCID: PMC10046013 DOI: 10.3390/cancers15061645] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 02/28/2023] [Accepted: 03/06/2023] [Indexed: 03/12/2023] Open
Abstract
Basaloid squamous cell carcinoma (BSCC) is a subtype of squamous cell carcinoma (SCC) associated with a poor prognosis. Tumor–stroma ratio (TSR) has been introduced as a prognostic feature in many solid tumors. TSR was investigated in a series of laryngeal BSCCs and compared with a group of stage-matched conventional SCCs (cSCCs), in both preoperative and surgical specimens, with the intent of ascertaining the more aggressive behavior of BSCC and verifying the presence of stromal-related causes. A series of 14 consecutive laryngeal BSCCs and a control group of 28 stage-matched conventional cSCCs were analyzed. A higher nodal metastasis presence was found in BSCCs (57.1% vs. 28.6%). The recurrence rate was 33.5% and 63.6% in the cSCC and BSCC groups; disease-free survival (DFS) was higher, though not significantly, in patients with cSCC. TSR, large cell nests, and tumor budding showed a moderate to very good agreement, and stroma type a good to very good agreement between biopsies and surgical specimens in the cSCC group. In the BSCC group, agreement was poor to very good for TSR and stroma type, and good to very good for large cell nests and tumor budding. Age was the only feature significant in predicting recurrence in the BSCC group (p = 0.0235). In cSCC, TSR low/stroma rich cases, when evaluated on biopsies or surgical specimens, were associated with lower DFS (p = 0.0036; p = 0.0041, respectively). Laryngeal BSCCs showed a lower DFS than cSCCs, even if statistical significance was not reached. TSR, evaluated in laryngeal biopsies and excised tumors, was prognostic in terms of DFS in cSCC but not in BSCC cases.

Abstract
BACKGROUND Whether extra-nodal extension (ENE+) and surgical margin positivity (margin+) are poor prognostic factors in HPV-associated (HPV+) oropharyngeal carcinoma (OPC) remains uncertain. RESULTS Our study evaluated if microscopic ENE+ and/or margin+ are associated poorer recurrence free survival (RFS) and overall survival (OS) in HPV+ OPC. Patients were classified as high risk (ENE+ and/or margin+) or low risk (ENE- and margins-). Of a total of 176 patients HPV+ OPC, 81 underwent primary surgery and dad data on ENE and margin status. There was no statistically significant difference in RFS (p = 0.35) or OS (p = 0.13) for high-risk versus low-risk groups. Ongoing smoking (p = 0.023), alcohol use (p = 0.044) and advanced stage (p = 0.019) were associated with higher risk of recurrence. Only advanced stage (p-value <0.0001) was associated poorer overall survival. CONCLUSIONS The presence of ENE+ and/or margin+ was not an independent predictor of poor RFS or OS in HPV+ OPC.

Worldwide prevalence of PI3K-AKT-mTOR pathway mutations in head and neck cancer: A systematic review and meta-analysis. Crit Rev Oncol Hematol 2021; 160:103284. [PMID: 33675910 DOI: 10.1016/j.critrevonc.2021.103284] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 02/03/2021] [Accepted: 02/27/2021] [Indexed: 02/07/2023] Open
Abstract
A systematic review (SR) and meta-analysis were conducted to determine the prevalence of PI3K-AKT-mTOR signaling pathway mutations in patients with head and neck cancer (HNC). Overall, 105 studies comprising 8630 patients and 1306 mutations were selected. The estimated mutations prevalence was 13 % for PIK3CA (95 % confidence interval [CI] = 11-14; I2 = 82 %; p < 0.0001), 4% for PTEN (95 % CI = 3-5; I2 = 55 %; p < 0.0001), 3% for MTOR (95 % CI = 2-4; I2 = 5%; p = 0.40), and 2% for AKT (95 % CI = 1-2; I2 = 50 %; p = 0.0001). We further stratified the available data of the participants according to risk factors and tumor characteristics, including HPV infection, tobacco use, alcohol exposure, TNM stage, and histological tumor differentiation, and performed subgroup analysis. We identified significant associations between PI3K-AKT-mTOR pathway-associated mutations and advanced TNM stage (odds ratio [OR] = 0.20; 95 % CI = 0.09-0.44; I² = 71 %; p = 0.0001) and oropharyngeal HPV-positive tumors and PIK3CA mutations (OR = 17.48; 95 % CI = 4.20-72.76; I² = 69 %; p < 0.0002). No associations were found between alcohol and tobacco exposure, and tumor differentiation grade. This SR demonstrated that the PI3K-AKT-mTOR pathway emerges as a potential prognostic factor and could offer a molecular basis for future studies on therapeutic targeting in HNC patients.

Abstract
PURPOSE HPV-related oropharyngeal squamous cell carcinomas clearly represent a growing entity in the head and neck with distinct carcinogenesis, clinico-pathological presentation and survival profile. We aimed to compare the HPV prevalence rates and clinico-pathological correlations obtained with three distinct commonly used HPV detection methods. MATERIALS AND METHODS p16-immunohistochemistry (IHC), HPV DNA viral load by real-time PCR (qPCR), and HPV genotyping by a reverse hybridization-based line probe assay (INNO-LiPA) were performed on pretreatment formalin-fixed paraffin-embedded tumor samples from 46 patients treated for single primary oropharyngeal carcinomas. RESULTS Twenty-eight patients (61%) had a p16 overexpression in IHC. Twenty-nine patients (63%) harbored HPV DNA on qPCR. Thirty-four patients (74%) harbored HPV DNA on INNO-LiPA. The concordance analysis revealed a good agreement between both HPV DNA detection methods (κ=0.65); when both tests were positive, the depicted HPV subtypes were always concordant (HPV16 in 27 cases, HPV18 in 1 case). Agreement was moderate between IHC and qPCR (κ=0.59) and fair between IHC and INNO-LiPA (κ=0.22). CONCLUSIONS Certain highly sensitive methods are able to detect the mere presence of HPV without any carcinogenetic involvement while other more specific tests provide proof of viral transcriptional activity and thus evidence of clinically relevant infections. The use of a stepwise approach allows reducing false positives; p16-immunostaining seems to be an excellent screening test and in situ hybridization may overcome some of the PCR limitations.

Abstract
In the recent years, basaloid squamous cell carcinomas (BSCCs) have gained attention because of (1) observation of a relative increase in the number of tumors arising particularly in head and neck sites, (2) identification of human papillomavirus (HPV) in BSCCs arising predominantly in the oropharynx, and (3) controversies that exist regarding the biological aggressiveness of the tumor. The objective of the present review was to address the issues mentioned above by focusing primarily on oral BSCCs, using literature that has been published in the English language up to 2013. According to the literature review, oral BSCCs were found to be relatively more common in elderly patients with a mean age of 64 years. A male predominance with a male/female ratio of 3:1 was observed. The predominant site was the tongue, with almost half of the reported cases occurring at this site, followed by the floor of the mouth and palate. With reference to habit history, majority were found to be tobacco and alcohol users. However, only 3 studies revealed data on HPV status of purely oral BSCC, and according to the results of these studies, of the 17 tumors tested, 4 had harbored high-risk HPV. Furthermore, most oral BSCCs were in an advanced clinical stage, namely, stage III or IV with T3 or T4 lesions and cervical lymph node metastasis at initial presentation, whereas 41% of patients had presented with local recurrences and 45% had died of the disease. In conclusion, although, the present literature review found enough evidence to consider tobacco and alcohol as risk factors for the development of oral BSCC, steps should be taken to fill the gap in our knowledge that exist with reference to contribution of oncoviruses, particularly HPV in the etiology of oral BSCC.

Abstract
Context.—Basaloid squamous cell carcinoma (bSCC) is an uncommon variant of squamous cell carcinoma, which may overlap histologically with basal cell carcinoma with squamous metaplasia (BCCm).
Objective.—To aid in the differentiation of these neoplasms using immunohistochemical staining because of the worse prognosis associated with bSCC.
Design.—Using immunohistochemical techniques, we investigated BerEp4, cytokeratin 17 (CK17), and cytokeratin 14 (CK14) protein expression in 25 cases of bSCC (8 cutaneous [32%], 12 aerodigestive tract [48%], and 5 lymph node metastases [20%]) and 43 cases of BCCm (39 cutaneous [91%], and 4 metastases [9%]). An immunoreactivity score was assigned using the percentage of tumor cells staining and the pattern of expression. Interobserver agreement for 2 independent pathologists was assessed using a κ coefficient.
Results.—The mean percentage of staining was significantly higher in BCCm, compared with bSCC (BerEp4, P = .006; CK17, P < .001; CK14, P < .001; unpaired t test), with 58% of BCCm cases (25 of 43) displaying diffuse staining for all markers, and nearly all (98%; 42 of 43) displaying diffuse staining for CK17 and CK14. In contrast, no bSCC cases (0%) displayed diffuse staining for all 3 markers, and only 8% (2 of 25) displayed diffuse staining for CK17 and CK14. High interobserver agreement was determined.
Conclusions.—BerEp4 alone is unreliable for differentiation between BCCm and bSCC, and the addition of either CK14 or CK17 will augment the sensitivity and negative predictive value of BerEp4 staining in BCCm and bSCC diagnosis.

Abstract
BACKGROUND Human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (SCC) is associated with favorable survival. The purpose of this study was to evaluate the prevalence and prognostic significance of the HPV infection through both the p16 expression status and the oncogenic HPV DNA viral load. METHODS A retrospective chart review was conducted on all patients treated for oropharyngeal SCC between January 2007 and June 2009. P16 expression status by immunohistochemistry and HPV DNA viral load by quantitative polymerase chain reaction (qPCR) were evaluated on routine pretreatment tumor samples. RESULTS One hundred thirty-three patients (94 men and 39 women) were included in the study. Mean age was 59 years. One hundred twenty-two lesions (92%) were localized to lymphoid areas. Sixty-seven patients (50%) were p16+, and 87 patients (65%) harbored HPV DNA. The p16+/HPV DNA+ profile (48%) was associated with the most favorable prognosis. HPV16 was responsible for the majority of the infections (89%). CONCLUSION HPV is common among oropharyngeal SCC in France, and acts as an independent prognostic factor.

Human papillomavirus-positive basaloid squamous cell carcinomas of the upper aerodigestive tract: a distinct clinicopathologic and molecular subtype of basaloid squamous cell carcinoma.

Abstract
Basaloid squamous cell carcinoma of the upper aerodigestive tract is a rare, morphologically distinct variant of squamous cell carcinoma that is thought to be clinically aggressive. The histologic features are distinct from, but often confused with, those of human papillomavirus-related oropharyngeal nonkeratinizing squamous cell carcinoma. The role of human papillomavirus as an etiologic agent in true basaloid squamous cell carcinoma is controversial. The purpose of this study was to determine human papillomavirus prevalence and its clinicopathologic significance in upper aerodigestive tract tumors with true basaloid squamous cell carcinoma histology. Twenty-eight cases were identified, 12 in the oropharynx and 16 in the larynx and/or hypopharynx. High-risk human papillomavirus in situ hybridization and immunohistochemistry for p16 and p53 were performed. Nine (75%) of the oropharyngeal and none of the larynx/hypopharynx tumors were human papillomavirus positive. Human papillomavirus-positive tumors affected younger patients. No significant statistical differences in patients' sex, tumor stage, treatment modality, or length of follow-up were observed between the 2 groups. Viral status showed a strong, positive correlation with p16 (P < .001) and a strong, negative correlation with p53 (P < .0001) immunoreactivity. Overall survival was better for human papillomavirus-positive basaloid squamous cell carcinomas (P < .05), with 86% of patients alive at 3 years compared with 35.3% of patients with human papillomavirus-negative tumors. These findings suggest that a subset of basaloid squamous cell carcinomas is virally driven. These tumors occur almost exclusively in the oropharynx, are molecularly distinct from their human papillomavirus-negative counterparts, and have a more favorable clinical outcome.

Abstract
Strong epidemiologic and molecular data now support the conclusion that human papillomavirus (HPV) infection is responsible for a distinct form of head and neck squamous cell carcinoma (HNSCC), independent from the traditional risk factors of tobacco and alcohol use. Patients with HPV-positive HNSCC have a different clinical presentation and better clinical outcomes than those with HPV-negative HNSCC. A diagnosis of HPV-positive HNSCC is associated not only with therapeutic relevance, but also has important implications for future prevention and screening strategies.

Abstract
Diagnosis of basaloid squamous carcinoma (BSCC) currently relies mainly on histological criteria, with variable immunohistochemical results reported in small series. We explored the use of a battery of immunohistochemical stains to elucidate this diagnosis on 45 cases of BSCC. To further elucidate the immunohistochemical profile of BSCC, to explore potential genetic pathways of malignant transformation using proliferation markers, and to investigate a possible link with Human Papillomavirus (HPV). Forty-five cases of BSCC and 34 site-matched cases of squamous cell carcinoma (SCC) were obtained from the archives of the pathology department at our institution. Extensive literature review was undertaken utilizing Medline. Ber-EP4 is a useful diagnostic marker for BSCC, positive in 82% (37/45) of the cases and in 68% (23/34) of SCC. An alternative is the combination of cytokeratins CK14 and CK7, known to be negative, and CK1, known to be positive, which achieves an accuracy of 73% (33/45) in BSCC and 88% (30/34) in SCC. The two diagnostic approaches were in agreement in 66% of the cases; both methods were equally accurate in the divergent cases. Increased expression of the proliferation markers supports the concept that BSCC is a rapidly growing tumor. Results of p16 stains support an etiological link between BSCC and HPV; interestingly, HPV was present significantly more in BSCC (71% (32/45)), than in SCC (59% (20/34)) in this study (P=0.02).

Abstract
CONTEXT Head and neck squamous cell carcinoma is commonly associated with tobacco and alcohol use. There are, however, a group of patients without a significant history of tobacco or alcohol use, and the etiology of these tumors is incompletely understood. OBJECTIVE To examine tumors in this subpopulation for association with human papillomavirus (HPV) using newly available in situ hybridization probes. DESIGN Between October 2004 and October 2005, 22 patients who did not use alcohol or tobacco were included. Formalin-fixed, paraffin-embedded tissue sections were used to perform in situ hybridization using newly available probe sets (Ventana Medical Systems, Tucson, Ariz). The slides were examined for the presence of integrated HPV using light microscopy. Positive and negative xenograft controls were run with the assay. Results.-The mean age of the patients was 64 years. There were 14 men and 8 women. The most common anatomic sites included tongue (n = 8), tonsil (n = 7), and larynx (n = 7). All cases and controls were successfully stained. Only 2 cases were positive for high-risk HPV, and both demonstrated an integrated pattern. Both cases were tumors of the tonsil. No cases were positive for low-risk HPV. CONCLUSIONS These results demonstrate that the new probe sets for HPV can be used very efficiently in clinical pathology material of head and neck squamous cell carcinoma. Our data show that high-risk HPV is an uncommon finding in head and neck squamous cell carcinoma from patients who do not have a history of tobacco or alcohol use; low-risk HPV was not seen in any case.

Abstract
BACKGROUND Basaloid squamous cell carcinoma (BSCC) is an uncommon, high-grade variant of squamous cell carcinoma (SCC) of the head and neck. Its poorer prognosis compared with common SCC remains controversial. The authors investigated the outcomes of patients with BSCC who received radiotherapy and compared them with the outcomes of patients with SCC. METHODS From 1994 to 2004, 1007 patients received radiotherapy for head and neck carcinoma with lymph node involvement. The histologic types consisted of 51 BSCC, 431 poorly differentiated SCC (PSCC), and 525 well or moderately differentiated SCC (WMSCC). A case-control analysis was performed with BSCC matched against both PSCC and WMSCC to compare disease-control and survival rates. RESULTS Patients with BSCC received treatment modalities similar to those received by patients with SCC: They received induction chemotherapy (12%) or concurrent chemotherapy (33%), and a median radiation dose of 70 Gray. Posttreatment viable tumor was present in 44%, 13%, and 28% of neck dissection specimens from patients with BSCC, PSCC, and WMSCC, respectively. The 5-year disease-free survival rates (63%, 77%, and 76%, respectively) and overall survival rates (85%, 70%, and 71%, respectively) demonstrated no statistically significant differences for BSCC, PSCC, or WMSCC, respectively. CONCLUSIONS In this study, a poorer prognosis could not be demonstrated for irradiated patients with BSCC compared with either PSCC or WMSCC. All patients in this study had positive lymph node status, and the majority of patients (84%) had oropharyngeal cancer. The BSCC cohort did have a relatively high rate of viable tumor in their posttreatment neck dissections, and they had a relatively high rate of distant disease. On the basis of the high rate of lung metastases and the possibility of efficient salvage, the authors recommend obtaining a chest computed tomography scan during initial staging and follow-up.

Abstract
Presence of human papillomavirus (HPV) in variable proportions in tonsillar squamous cell carcinoma tissues has been demonstrated by several worldwide studies. Some reports emphasized the significance of HPV in predicting a better prognosis, as well as ethnic differences between Chinese and Caucasians. In order to understand the biological role of HPV and find out clinically accessible methods to determine its prognostic significance in primary tonsillar squamous cell carcinoma, we collected 92 patients with primary tonsillar squamous cell carcinoma diagnosed or treated in National Taiwan University Hospital, for whom archival tumor tissue were available. Immunohistochemical stains of p16(INK4A), high-risk HPV in situ hybridization, and nested polymerase chain reaction (PCR)-based genechips were performed to detect HPV infection and determine its genotype. Clinical data were compared with HPV infection detected by the different methods mentioned above. Real-time PCR was also performed on the HPV16-positive [HPV16(+)] lesions to understand viral integration status. The positive rates of nested PCR-based genechips, overexpression of p16(INK4A), and high-risk HPV in situ hybridization were 75% (69/92), 53% (49/92), and 44% (40/92), respectively. Both overexpression of P16(INK4A) and high-risk HPV in situ hybridization positivity were associated with favorable prognoses (P=0.004 and 0.001, respectively) and also independent prognostic factors in multivariate analyses (P=0.01 and 0.01, respectively). The positivity of nested PCR-based genechips was not statistically significant. From our data, primary tonsillar squamous cell carcinoma with positive immunohistochemical stains of p16(INK4A) and/or high-risk HPV in situ hybridization is associated with a better outcome, and both methods may serve as clinically accessible markers.

Abstract
The epidemiological link between human papillomavirus (HPV) DNA and basaloid squamous cell carcinoma (BSCC) of the pharynx was studied. The expression of p53 protein was evaluated by immunohistochemical analysis. The presence of HPV DNA was evaluated by polymerase chain reaction amplification and "in situ" hybridization. The tobacco and alcohol consumption and the clinical outcomes of nine patients with BSCC of the pharynx are compared with site and stage matched 109 conventional squamous cell carcinoma (SCC) patients. The BSCC specimens were analyzed for the presence of HPV DNA and p53 expression. We did not find any significant differences in tobacco and alcohol consumption between patients with BSCC and patients with SCC. No HPV DNA was detected in BSCC, and p53 overexpression was found in five (55%) of the cases. Our results do not support an etiological link between HPV DNA and BSCC.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is a leading cause of cancer mortality worldwide. Recent reports have associated a subset of HNSCC with high-risk human papillomaviruses (HPVs), particularly HPV16, the same subset of HPVs responsible for the majority of cervical and anogenital cancers. In this study we describe a mouse model for HPV-associated HNSCC that employs mice transgenic for the HPV16 oncogenes E6 and E7. In these mice, E6 and E7 induce aberrant epithelial proliferation and, in the presence of a chemical carcinogen, they increase dramatically the animal's susceptibility to HNSCC. The cancers arising in the HPV16-transgenic mice mirror the molecular and histopathological characteristics of human HPV-positive HNSCC that distinguish the latter from human HPV-negative HNSCC, including overexpression of p16 protein and formation of more basaloid cancers. This validated model of HPV-associated HNSCC provides the means to define the contributions of individual HPV oncogenes to HNSCC and to understand the molecular basis for the differing clinical properties of HPV-positive and HPV-negative human HNSCC. From this study, we identify minichromosome maintenance protein 7 (MCM7) and p16 as potentially useful biomarkers for HPV-positive head and neck cancer.

Abstract
Human papillomavirus (HPV) is now recognized to play a role in the pathogenesis of a subset of head and neck squamous cell carcinomas (HNSCCs), particularly those that arise from the lingual and palatine tonsils within the oropharynx. High-risk HPV16 is identified in the overwhelming majority of HPV-positive tumors, which have molecular-genetic alterations indicative of viral oncogene function. Measures of HPV exposure, including sexual behaviors, seropositivity to HPV16, and oral, high-risk HPV infection, are associated with increased risk for oropharyngeal cancer. HPV infection may be altering the demographics of HNSCC patients, as these patients tend to be younger, nonsmokers, and nondrinkers. There is sufficient evidence to conclude that a diagnosis of HPV-positive HNSCC has significant prognostic implications; these patients have at least half the risk of death from HNSCC when compared with the HPV-negative patient. The HPV etiology of these tumors may have future clinical implications for the diagnosis, therapy, screening, and prevention of HNSCC.

Abstract
Squamous cell carcinoma of the head and neck (HNSCC) is a heterogeneous but largely preventable disease with complex molecular abnormalities. It arises from a premalignant progenitor followed by outgrowth of clonal populations associated with cumulative genetic alterations and phenotypic progression to invasive malignancy. These genetic alterations result in inactivation of multiple tumour suppressor genes and activation of proto-oncogenes, including p16(ink4A), p53, cyclin D1, p14(ARF), FHIT, RASSF1A, epidermal growth factor receptor (EGFR), and Rb. Intramucosal migration and clonal expansion of transformed cells with formation of abnormal genetic fields appear to be responsible for local recurrences and development of second primary tumours.

Abstract
CONCLUSION Nuclear expression of survivin should be studied as a promising marker of higher-risk laryngeal basaloid squamous cell carcinomas (BSCCs), which can then be treated more aggressively and followed more closely. OBJECTIVE BSCC is an uncommon bimorphic variant of SCC. The hypothesized greater aggressiveness and poorer prognosis of head and neck BSCC compared to SCC are still under debate. The regulation of apoptotic cell death has a profound effect on the pathogenesis and progression of malignancies. Survivin is the smallest member of the inhibitor of apoptosis gene family. The aim of this study was to investigate for the first time the expression of the inhibitor of apoptosis protein survivin in laryngeal BSCCs and their neck lymph node metastases and to compare the results with those obtained with conventional SCCs. MATERIAL AND METHODS Immunoreactivity to survivin was determined in nine laryngeal BSCCs and nine site- and stage-matched SCCs. RESULTS A nuclear subcellular localization of survivin dominated in both primary laryngeal BSCCs and SCCs and in their lymph node metastases. There was no significant difference in mean survivin expression between primary laryngeal BSCCs (25.1%) and SCCs (25.6%) (p=0.86). Nuclear survivin expression was significantly higher in BSCCs associated with disease recurrence and poor prognosis (p=0.02).

Abstract
CONCLUSIONS This comparison of neo-angiogenesis performed by analysing CD105 expression seems to suggest that the biological behaviour of head and neck BSCCs is similar to that of site- and stage-matched conventional SCCs. OBJECTIVE Basaloid squamous cell carcinoma (BSCC) is an uncommon, high-grade biomorphic variant of SCC with a predilection for the head and neck region. It is a matter of controversy whether the biological and clinical behaviour of BSCC is more aggressive than that of SCC. Angiogenesis is essential for tumour growth. It has been established that endothelial cells of tumour-associated neovasculature proliferate more rapidly than endothelial cells of normal tissue. Endoglin (CD105) has been shown to be a useful marker for identifying proliferating endothelium involved in tumour angiogenesis. The aim of this study was to investigate the expression of CD105 in head and neck BSCCs and to compare it with that in SCCs. MATERIAL AND METHODS Nine head and neck BSCCs (five cases in the larynx, three in the tongue and one in the tonsil) were considered. A group of nine site- and stage-matched SCCs was examined simultaneously. For each sample, CD105 reactivity was evaluated immunohistochemically. The mean area fraction (percentage of fields occupied by vessels), the percentage of vessel-presenting fields and the vessel density were considered. RESULTS The median values of the mean area fraction were 1.01% and 0.9% in BSCCs and SCCs, respectively. The median values of the percentage of vessel-presenting fields were 57.5% and 46.67% in BSCCs and SCCs, respectively. The median values of vessel density were 2.07% and 1.58% in BSCCs and SCCs, respectively. Statistical analysis did not disclose any significant differences between BSCCs and SCCs for any of the above-mentioned parameters.

Abstract
There is currently sufficient evidence to conclude that human papillomavirus (HPV) plays a role in the pathogenesis of a distinct subset of head and neck squamous cell cancers (HNSCC), particularly tonsillar cancers. There is a strong and consistent association between high-risk HPV types, specifically HPV16, a known human carcinogen, and these distinctive oropharyngeal cancers with molecular characteristics indicative of viral oncogene function. Risk for HPV-HNSCC is increased by certain sexual behaviors after consideration of alcohol and tobacco exposure, consistent with an extensive literature that has established HPV infection as a sexually transmitted disease. Furthermore, exposure to HPV16 has been associated with increased risk for subsequent development of oropharyngeal cancer. Prophylactic and therapeutic vaccines targeted against the viral capsid components and oncoproteins will provide the ultimate evidence for a role for HPV in HNSCC, if demonstrated to be effective in the prevention or therapy of this disease. It is time for clinician scientists to translate knowledge of this newly recognized disease entity into potential applications for the prevention, detection, and treatment of HPV-HNSCC.

Abstract
OBJECTIVES/HYPOTHESIS The prevalence of human papillomavirus (HPV), herpes simplex virus (HSV), cigarette smoking and alcohol abuse was compared between two histological subgroups of head and neck cancer. STUDY DESIGN Retrospective review. METHODS Paraffin-embedded, histologically confirmed surgical specimens from the oropharynx, hypopharynx and larynx, comprising 67 conventional squamous cell carcinomas (SCC) and 10 basaloid squamous cell carcinomas (BSCC), were analyzed for the presence of HPV and HSV DNA using polymerase chain reaction (PCR) techniques. The PCR products were verified by direct sequencing. Patient charts were reviewed for clinical data and risk factors. RESULTS Given an overall HPV DNA detection rate of 32.5%, a basaloid morphology of the carcinomas correlated significantly with occurrence of HPV DNA (P =.0001). An association could also be demonstrated between basaloid appearance and evidence of HSV DNA (single and combined with HPV DNA; P =.014 and 0.0429, respectively), even if this result based on a low overall HSV DNA detection rate (6.5%). Demonstration of viral DNA in the BSCC specimens was not related to tobacco or alcohol consumption. In contrast, cigarette smoking proved as significant characteristic of SCC (P =.0087). Alcohol abuse occurred also predominately in patients with SCC, but without statistical significance. CONCLUSION These results hint at differences in the etiology of two distinct histological entities of head and neck cancer. Further research in this field could complete these preliminary data and provide the background for specific preventive strategies.
