Abstract
OBJECTIVE Head-neck cancer therapy has become intensified. With radiotherapy alone, 3-year disease-free survival (DFS) is 80% for HPV-positive TSCC/BOTSCC and better for patients with favorable characteristics, suggesting therapy could be tapered for some, decreasing side-effects. Therefore, we built a model to predict progression-free survival for patients with HPV-positive TSCC and BOTSCC. MATERIAL AND METHODS TSCC/BOTSCC patients treated curatively between 2000 and 2011, with HPV16 DNA/E7 mRNA positive tumors examined for CD8+ TILs, HPV16 mRNA and HLA class I expression were included. Patients were split randomly 65/35 into training and validation sets, and LASSO regression was used to select a model in the training set, the performance of which was evaluated in the validation set. RESULTS 258 patients with HPV DNA/E7 mRNA positive tumors could be included, 168 and 90 patients in the respective sets. No treatment improved prognosis compared to radiotherapy alone. CD8+ TIL counts and young age were the strongest predictors of survival, followed by T-stage <3 and presence of HPV16 E2 mRNA. The model had an area under curve (AUC) of 76%. A model where the presence of three of four of these markers defined good prognosis captured 56% of non-relapsing patients with a positive predictive value of 98% in the validation set. Furthermore, the model identified 35% of our cohort that was overtreated and could safely have received de-escalated therapy. CONCLUSION CD8+ TIL counts, age, T-stage and E2 expression could predict progression-free survival, identifying patients eligible for randomized trials with milder treatment, potentially reducing side effects without worsening prognosis.

Abstract
Human papillomavirus (HPV) infection is a risk factor for oropharyngeal cancer, besides smoking and alcohol. Patients with HPV-positive tumors have a better prognosis than those with HPV-negative tumors. Furthermore, patients with HPV-positive tumors, with high CD8+ tumor infiltrating lymphocyte counts or absent/low human leukocyte antigen (HLA) class I expression have the best outcome. The latter is paradoxical, since HLA class I expression is important for tumor recognition. Below, the hypothesis that radiation therapy increases HLA class I expression was tested. HPV16 positive head and neck cancer cell lines UPCI-SCC-154, UPCI-SCC-090 and UM-SCC-47, and the HPV-negative cancer cell line UT-SCC-14, were treated with 2-10 Gray (Gy) and tested for HLA class I expression, cell cycle changes and apoptosis by flow cytometry. HPV16 E5, E7 and HLA-A mRNA expression was tested by quantitative PCR. A dose of 10 Gy resulted in a tendency of increased HLA class I cell surface expression for all cell lines and reached statistical significance for UPCI-SCC-154 and UPCI-SCC-090. There were, however, no significant changes in HLA-A mRNA expression in any of the cell lines, or HPV16 E5, or E7 mRNA expression for UPCI-SCC-47 and UPCI-SCC-154, while for UPCI-SCC-090 HPV16 E5 mRNA decreased. In all cell lines there was a shift towards G2/M phase and increased apoptosis after irradiation with 10 Gy. To conclude, irradiation with 10 Gy increased HLA class I expression in the HPV-positive cell lines UPCI-SCC-154 and UPCI-SCC-090. A similar tendency was observed for HPV-positive UM-SCC-47 and HPV-negative UT-SCC-14.

Abstract
BACKGROUND The role of human papillomavirus (HPV) in tonsillar squamous cell carcinomas (TSCC) is of interest, since a considerable proportion of TSCC in Sweden and other Western countries is HPV positive. Nevertheless, the natural history of HPV in normal tonsils, and the progression from localized infection to pre-malignant lesion to cancer are poorly understood. The aim of this study was to investigate whether HPV types found in mouthwash samples correlated to those in tonsillar tissue from the same individuals undergoing tonsillectomy. METHODS Mouthwash samples from 232 patients, aged 3-56 years, undergoing tonsillectomy, the majority with chronic tonsillitis, were collected at the time of surgery and analysed for the presence of 27 HPV types by a bead based multiplex assay. RESULTS An HPV prevalence of 10.3% (24/232) was observed in mouthwash samples, with HPV 69 being the dominant type (10/24). Ten patients were positive for high risk HPV (HPV 16, 33, 35, 45, 56, 59). None of the tonsils resected from patients with HPV-positive mouthwash samples were positive for HPV. CONCLUSIONS Despite an oral HPV prevalence of 10.3% in mouthwash samples from tonsillectomized patients, with dominance of HPV 69, none of the corresponding tonsillar samples exhibited the presence of HPV.

Abstract
BACKGROUND Human papillomavirus (HPV) is a favourable prognostic factor in oropharyngeal cancer. Moreover, we and others reported that HPV-positive cancer of unknown primary in the head and neck region (HNCUP) has better outcome than HPV-negative HNCUP. However, not all studies concord. Here, our previous finding was investigated in a new cohort and additional biomarkers were analyzed. MATERIALS AND METHODS A total of 19 HNCUPs diagnosed 2008-2013 were analyzed for HPV DNA by polymerase chain reaction assay (PCR) and p16 by immunohistochemistry (IHC). Thereafter, 69 HNCUPs diagnosed between 2000-2013 were analyzed for HPV16 mRNA by PCR (if HPV16DNA-positive) and cluster of differentiation 8 positive (CD8+) tumour-infiltrating lymphocytes (TILs) and human leukocyte antigen (HLA) class I-expression using IHC. RESULTS HPV DNA, alone and in combination with p16 overexpression, was validated as a favourable prognostic factor in HNCUP. HPV16 mRNA was present in most HPV16 DNA-positive cases, confirming HPV-driven carcinogenesis in HNCUP. High CD8+ TIL counts indicated favourable prognosis. CONCLUSION HPV status is useful for the management of patients with HNCUP and the role of CD8+ TILs should be further explored.

Abstract
BACKGROUND BK polyomavirus (BKPyV) can cause hemorrhagic cystitis (HC) in allogeneic hematopoietic stem cell transplant (allo-HSCT) patients and polyomavirus-associated nephritis in renal transplant patients, while JC polyomavirus (JCPyV) can generate progressive multifocal leukoencephalopathy in immunocompromised individuals. Since 2007, additional human polyomaviruses (HPyVs) have been identified. In this study, we examined the urines of allo-HSCT patients for possible presence of polyomaviruses BKPyV, JCPyV, KIPyV, WUPyV, MCPyV, HPyV6, HPyV7, TSPyV, HPyV9, and HPyV10 (MWPyV). METHODS A total of 185 urinary samples obtained 2002-2007 from 105 allo-HSCT patients, 32/105 with HC, were tested for the above-listed HPyVs by a bead-based multiplex assay. Of these, 142 urine samples had previously been tested for BKPyV and JCPyV by nested polymerase chain reaction (PCR). RESULTS Aside from BKPyV and JCPyV, which dominated, HPyV7 was detected in 5 BKPyV-positive urinary samples from 1 patient. The multiplex assay was more sensitive and specific than the nested PCR. BKPyV and/or JCPyV were found in all but 1 of the previously BKPyV- or JCPyV-positive samples, although 6 previously BKPyV-positive cases were now JCPyV-positive or the reverse. Furthermore, 18/79 previously negative samples were found to be BKPyV and/or JCPyV positive, and a total of 21 double infections were found. Lastly, in 1/29 HC patients, only JCPyV was detected. CONCLUSION HPyV7 was found for the first time in urine of an allo-HSCT patient, and BKPyV and JCPyV were more commonly found in urine samples using the bead-based assay compared to testing by nested PCR. Finally, only JCPyV was detected in the urine of 1 HC patient.

Abstract
BACKGROUND Human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (SCC) has a better outcome than most head neck squamous cell carcinomas (HNSCCs) and an HPV-positive lymph node metastasis likely has an HPV-positive oropharyngeal SCC origin. Determining HPV-status in cervical lymph nodes by fine-needle aspiration cytology (FNAC) may be useful for diagnosis. METHODS FNACs from 66 patients with neck masses were prospectively examined for HPV DNA and HPV16 mRNA by a polymerase chain reaction (PCR)-based assay, and the data correlated to diagnosis and HPV-status obtained from histopathological specimens. RESULTS Aspirates from 17 of 66 patients, later diagnosed with HPV-positive oropharyngeal SCC, were HPV16 DNA-positive. HPV16 mRNA was detected in all cases with extractable RNA. All remaining FNACs, including 18 branchial cleft cysts, were HPV DNA-negative. HPV DNA status in the aspirates showed perfect concordance with corresponding biopsies. CONCLUSION HPV16 DNA detection in fine-needle aspirations from neck masses is reliable and HPV16 DNA in a metastasis is a strong indicator of an HPV-positive oropharyngeal SCC. © 2016 Wiley Periodicals, Inc.

Abstract
Human papillomavirus (HPV), in addition to smoking and alcohol, is a cause of oropharyngeal squamous cell carcinoma (OPSCC), particularly of the tonsils and base of the tongue (TSCC and BOTSCC, respectively). Moreover, HPV-positive TSCC and BOTSCC are associated with a better outcome compared with their HPV-negative counterparts (80 vs. 40% 3-year disease-free survival rate, respectively) and their incidence has increased in several countries. Recently, accumulating evidence of HPV in a considerable proportion of cancers of unknown primary (CUP) in the head and neck region and in a small proportion of hypopharyngeal SCCs has been reported. Furthermore, HPV-positive tumours, particularly cases with HPV DNA positivity in combination with overexpression of p16, also tend to have a better clinical outcome compared with that of the corresponding HPV-negative tumours. This finding is particularly prominent in HPV-positive CUPs of the head and neck region, where the primary tumour likely originates from the oropharynx. Thus, the determination of HPV status and p16 expression may be of value for the diagnosis and treatment of CUP of the head and neck region and may also be of value for hypopharyngeal cancers in the future. However, for hypopharyngeal cancer as well as other non-OPSCCs, additional studies per subsite on the effect of HPV status on survival are required.

Abstract
Human papillomavirus (HPV) is recognized as a risk factor for oropharyngeal squamous cell carcinomas (SCC), especially tonsillar and base of tongue cancer. Furthermore, HPV-positive tonsillar and base of tongue SCC have a significantly better prognosis than their HPV-negative counterparts and head and neck cancer (HNSCC) in general. HPV has recently also been implicated in cancer of unknown primary (CUP) in the head and neck region, where a primary tumour is not found despite extensive workup. Using fine-needle aspiration cytology to determine CUP HPV status in cervical lymph nodes could be of advantage, since it is minimally invasive and it is assumed that an HPV-positive lymph node metastasis likely has an HPV-positive otopharyngeal SCC origin. We review the current knowledge of HPV in HNSCC, with an emphasis on CUP of the head and neck region, its relation to oropharyngeal, tonsillar and base of tongue SCC and implications of HPV status for diagnosis, prognosis and treatment.

Abstract
OBJECTIVE To improve primary prevention of human papillomavirus (HPV) infection by promoting vaccination and increased condom use among upper secondary school students. DESIGN Cluster randomised controlled trial. SETTING 18 upper secondary schools in Sweden. PARTICIPANTS Schools were first randomised to the intervention or the control group, after which individual classes were randomised so as to be included or not. Of the 832 students aged 16 years invited to participate during the regular individual health interview with the school nurse, 751 (90.2%) agreed to participate and 741 (89.1%) students completed the study. INTERVENTIONS The intervention was based on the Health Belief Model (HBM). According to HBM, a person's health behaviour can be explained by individual beliefs regarding health actions. School nurses delivered 30 min face-to-face structured information about HPV, including cancer risks and HPV prevention, by propagating condom use and HPV vaccination. Students in the intervention and the control groups completed questionnaires at baseline and after 3 months. MAIN OUTCOME MEASURES Intention to use condom with a new partner and beliefs about primary prevention of HPV, and also specifically vaccination status and increased condom use. RESULTS All statistical analyses were performed at the individual level. The intervention had a significant effect on the intention to use condom (p=0.004). There was also a significant effect on HBM total score (p=0.003), with a 2.559 points higher score for the intervention group compared to the controls. The influence on the HBM parameters susceptibility and severity was also significant (p<0.001 for both variables). The intervention also influenced behaviour: girls in the intervention group chose to have themselves vaccinated to a significantly higher degree than the controls (p=0.02). No harms were reported. CONCLUSIONS The school-based intervention had favourable effects on the beliefs about primary prevention of HPV, and increased the HPV vaccination rates in a diverse population of adolescents.

Abstract
AIM To combine clinical and molecular markers into an algorithm for predicting outcome for individual patients with human papillomavirus (HPV) DNA/p16(INK4a) positive tonsillar and base of tongue squamous cell carcinoma (TSCC and BOTSCC). BACKGROUND Head-neck cancer treatment has become more intensified, comprising not only surgery and radiotherapy, but also induction/concomitant chemotherapy and targeted therapy. With less treatment, 3-year disease free survival (DFS) is 80% for HPV-positive TSCC and BOTSCC. An 85-100% 3-year DFS is observed for HPV(+) TSCC and BOTSCC with absence of HLA class I, or CD44 expression, or high CD8(+) tumour-infiltrating lymphocyte (TIL) counts suggesting that therapy could be tapered for many if patients could be identified individually. PATIENTS AND METHODS Patients treated curatively, with HPV DNA/p16(INK4a) positive tumours examined for HLA class I and II, CD44 and CD8(+)TILs, were included. An L1-regularised logistic regression was used to evaluate the effect of the biomarker data, age, stage, diagnosis, smoking and treatment on 3-year risk of death or relapse on a training cohort of 197 patients diagnosed 2000-2007 and validated on a cohort of 118 patients diagnosed 2008-2011. RESULTS The variables finally included in the model were HLA class I, CD8(+) TILs, age, stage and diagnosis (TSCC or BOTSCC). The model showed acceptable discrimination and calibration. The discriminative ability of the model did not diminish after validation (AUC=0.77). CONCLUSION To our knowledge, this is the first model to utilise information from several markers to predict an individual probability of clinical outcome for patients with HPV DNA/p16(INK4a) positive tumours.

Abstract
In 2007, human papillomavirus (HPV) type 16 was recognized as a risk factor by the International Agency for Research on Cancer, for oropharyngeal squamous cell carcinoma (OSCC), where tonsillar and base of tongue cancer (TSCC and BOTSCC) dominate. Furthermore, patients with HPV-positive TSCC and BOTSCC, had a much better clinical outcome than those with corresponding HPV-negative cancer and other head and neck cancer. More specifically, survival was around 80% for HPV-positive TSCC and BOTSCC vs. 40% five-year disease free survival, for the corresponding HPV-negative tumors with conventional radiotherapy and surgery, while this could not be observed for HPV-positive OSCC at other sites. In addition, the past 20-40 years in many Western Countries, the incidence of HPV-positive TSCC and BOTSCC has risen, and >70% are men. This has resulted in a relative increase of patients with HPV-positive TSCC and BOTSCC that may not need the intensified chemo-radiotherapy (with many more severe debilitating side effects) often given today to patients with head and neck cancer. However, before tapering therapy, one needs to enable selection of patients for such treatment, by identifying clinical and molecular markers that together with HPV-positive status will better predict patient prognosis and response to therapy. To conclude, there is a new increasing group of patients with HPV-positive TSCC and BOTSCC with good clinical outcome, where options for better-tailored therapy are needed. For prevention, it would be of benefit to vaccinate both girls and boys against HPV16 infection. For potential future screening the ways to do so need optimizing.

Abstract
OBJECTIVES: Patients with human papillomavirus (HPV)–positive tonsillar squamous cell carcinoma (TSCC) and base of tongue squamous cell carcinoma (BOTSCC) have a better clinical outcome than those with corresponding HPV-negative tumors. Moreover, there is a strong positive correlation between absent/low as opposed to strong HLA class I expression and favorable clinical outcome for HPV-positive tumors, while the reverse applies to HPV-negative tumors. The expression of the antigen processing machinery (APM) components TAP1, TAP2, LMP2, and LMP7 in these tumors in relation to HPV status, HLA class I expression, each other, and clinical outcome was therefore investigated. MATERIAL AND METHODS: Formalin-fixed paraffin-embedded TSCC and BOTSCC, derived from 151 patients and previously analyzed for HPV DNA, HLA class I, and LMP10 expression were stained by immunohistochemistry for TAP1, TAP2, LMP2, and LMP7. RESULTS: Absent/low TAP2, LMP2, and LMP7 expression, similar to HLA class I and LMP10, was common in TSCC and BOTSCC, irrespective of HPV status. Expression of TAP1 and TAP2 was correlated, as was LMP2 to LMP7. LMP2 and LMP7 expression was also associated to HLA class I expression. Moreover, absence of LMP7 was linked to increased disease-free survival in both HPV-positive and HPV-negative cases. CONCLUSION: Reduced expression of TAP2, LMP2, and LMP7 was frequent in TSCC and BOTSCC and their expression as well as that of TAP1 was often interrelated. Furthermore, low LMP7 expression correlated to better clinical outcome and may, together with HPV status, potentially be used for prediction of treatment response.

Abstract
Numerous reports in recent decades have shown that, in addition to smoking and alcohol, human papillomavirus (HPV) is also associated with the development of oropharyngeal squamous cell carcinoma (OPSCC), predominantly in the tonsils and base of the tongue. In 2007, the International Agency on Research against Cancer (IARC) therefore declared HPV to be a risk factor for OPSCC and noted that 80% of those affected are men. In addition, patients with HPV-positive OPSCC, in particular never-smokers, have a much better clinical response to therapy than patients with HPV-negative OPSCC and other head and neck cancers. Most patients with HPV-positive OPSCC may thus not need the increasingly intensive chemo-radiotherapy currently administered today to most patients with head neck cancers and associated with many adverse effects. Furthermore, an increase in the incidence of OPSCC has been observed in many western countries, accompanied by a rise in the proportion of HPV-positive tumors. Patients with HPV-positive OPSCC, like those with cervical cancer, more often have an earlier sexual debut and have more sexual partners. It has therefore been proposed that the increased incidence of OPSCC observed might be due to an epidemic of sexually transmitted HPV. The important issues today regarding this growing cohort of patients with HPV-positive OPSCC are therefore individualized treatment and prevention. More specifically, selected HPV-positive OPSCC patients with biomarkers of good prognosis might be included in randomized trials with less intensive treatment. HPV vaccination should also be considered for boys, in addition to the current recommendations for immunization of girls.

Abstract
During 2009-2011, we reported that the oral and cervical prevalence of human papillomavirus (HPV) was high by international standards at 9.3% and 74%, respectively, in youth aged 15-23 years attending a youth clinic in Stockholm. After gradual introduction of public HPV vaccination during 2007-2012, between 2013 and 2014, when 73% of the women were HPV-vaccinated, but not necessarily before their sexual debut, oral HPV prevalence had dropped to 1.4% as compared with 9.3% in 2009-2011 (p < 0.00001). Cervical HPV prevalence was high and common cervical high-risk types were HPV51, 56, 59, 73, 16, 39, 52, and 53. However, it was shown that HPV16, 31, and 70 were significantly less common among HPV-vaccinated women than among those who had not received the vaccine.

Abstract
BACKGROUND/AIM Patients with human papillomavirus (HPV)-positive tonsillar and base of tongue cancer have a better outcome than those with corresponding HPV-negative tumors (80% vs. 40% 5-year disease free survival with conventional radiotherapy). They should not all need chemoradiotherapy, but before tapering treatment, more markers are needed to predict treatment response. In the present study, human leukocyte antigen (HLA) - HLA-A*02 was analyzed with HPV as a prognostic factor for tonsillar and base of tongue cancer. PATIENTS AND METHODS Pre-treatment biopsies, previously tested for HPV DNA, from 425 patients diagnosed with tonsillar and base of tongue cancer between 2000-2009 at the Karolinska University Hospital were examined for HLA-A*02. RESULTS HLA-A*02 was present in 144/305 (47.2%) of the HPV-positive and 63/120 (52.8%) of the HPV-negative tumours. Among 383 patients treated with curative intent, absence of HLA-A*02 was correlated with increased disease-free survival in the HPV-positive (p=0.016), but not in the HPV-negative group. CONCLUSION Absence of HLA-A*02 correlated with better disease-free survival for patients with HPV-positive tonsillar and base of tongue cancer.

Abstract
AIM To examine LMP10 expression and its possible impact on clinical outcome in human papillomavirus (HPV) positive and HPV-negative tonsillar and base of tongue squamous cell carcinoma (TSCC and BOTSCC). BACKGROUND Outcome is better in HPV-positive TSCC and BOTSCC compared to matching HPV-negative tumours, with roughly 80% vs. 40% 5-year disease free survival (DFS) with less aggressive treatment than today's chemoradiotherapy. Since current treatment often results in harmful side effects, less intensive therapy, with sustained patient survival would be an attractive alternative. However, other markers together with HPV status are necessary to select patients and for this purpose LMP10 expression is investigated here in parallel to HPV status and clinical outcome. MATERIALS AND METHODS From 385 patients diagnosed between 2000 and 2007 at the Karolinska University Hospital, 278 formalin fixed paraffin embedded TSCC and BOTSCC biopsies, with known HPV DNA status, were tested for LMP10 nuclear and cytoplasmic expression (fraction of positive cells and staining intensity). The data was then correlated to clinical outcome. RESULTS An absent/low compared to a moderate/high LMP10 nuclear fraction of positive cells was correlated to a better 3-year DFS in the HPV-positive group of patients (log-rank p = 0.005), but not in the HPV-negative group. In the HPV-negative group of patients, in contrast to the HPV-positive group, moderate/high LMP10 cytoplasmic fraction and weak/moderate/high LMP10 cytoplasmic intensity correlated to a better 3-year DFS (p = 0.003 and p = 0.001) and 3-year overall survival (p = 0.001 and 0.009). CONCLUSION LMP10 nuclear expression in the HPV-positive group and LMP10 cytoplasmic expression in the HPV-negative group of patients correlated to better clinical outcome.

Abstract
MATERIAL AND METHODS Presence of HPV DNA was analyzed in mouthwash and tonsillar swab samples, if indicative of HPV-positive tonsillar or base of tongue cancer in 76 patients, with suspected head neck cancer, undergoing diagnostic endoscopy at Karolinska University Hospital. The diagnosis and tumor HPV status was later obtained from patients' records. As controls, 37 tumor-free dental visitors were included. RESULTS Of the 76 patients, 22/29 (76%) and 16/18 (89%) had an HPV-positive tonsillar and base of tongue cancer respectively, with 18/22 (82%) and 8/16 (50%) respectively having tumor concordant HPV-type positive oral samples. Two other HPV-positive oral samples in the base of tongue cancer group did not correlate to the tumor HPV status. Among the remaining patients, 19 with other head neck cancer and 10 with benign conditions, 4/29 (14%) had HPV-positive oral samples. Consequently, of the HPV-positive oral samples, dominated by HPV16 and high signals, 27/32 (84%) were derived from 26 patients with concordant HPV-type positive tonsillar or base of tongue cancer and one patient with an unknown primary head and neck cancer. The other five HPV-positive oral samples, with mainly low signals were derived from two patients with non-concordant HPV-type positive tumor biopsies, two patients with HPV-negative tumor biopsies and a patient with a benign condition. Of the dental patients, 3/37 (8%) had HPV-positive tonsillar swabs with weak signals. CONCLUSION In patients with suspected head neck cancer, HPV-positive oral samples, especially HPV16 with high signals, could be indicative of HPV-positive tonsillar or base of tongue cancer.

Abstract
OBJECTIVES To investigate sexual experiences, sexually transmitted infections (STIs) and use of condoms in relation to human papillomavirus (HPV)-vaccination status in female high school students. METHODS In 2013, 355 female students with a median age of 18 years from randomly selected high schools in Sweden answered a classroom questionnaire on sexual experiences and HPV-vaccination status. RESULTS In total 227/348 (65%) of the women reported having received at least one HPV vaccine dose. Median age at first intercourse was 15 and 16 years respectively, in the 141/227 (62%) vaccinated after, and the 86/227 (38%) vaccinated before their sexual debut. There were no differences between the HPV-vaccinated and non-vaccinated groups regarding condom use, STIs, and experiences of oral and anal sex, or friends- with-benefit relationships. However, having had sexual intercourse and 'one-night stands' were more common in the vaccinated group (both p < 0.05). CONCLUSION Many students (62%) were vaccinated against HPV, with two-thirds after their sexual debut. There were no differences in condom use and STIs, and only a few differences in sexual experiences between the HPV-vaccinated and non-vaccinated groups. Initiating HPV vaccination before sexual debut is important, as is information about the link between HPV, sexual behaviour and cancer.

Abstract
Background: The incidence of human papillomavirus (HPV)-associated oropharyngeal cancer has increased rapidly during the past decades. HPV is typically associated with a favourable outcome; however, a need exists for new and more effective prognostic and predictive markers for this disease. Leucine-rich repeats and immunoglobulin-like domains (LRIG)-1 is a tumour suppressor protein that belongs to the LRIG family. LRIG1 expression has prognostic significance in various human cancers, including cervical cancer, where HPV is a key aetiological agent. Methods: The prognostic value of LRIG1 and LRIG2 immunoreactivity was investigated in tumour specimens from a Swedish cohort of patients with tonsillar and base of tongue oropharyngeal cancers, including 278 patients. Results: LRIG1 immunoreactivity correlated with disease-free survival and overall survival in univariate and multivariate analyses. Notably, patients with HPV-positive tumours with high LRIG1 staining intensity or a high percentage of LRIG1-positive cells showed a very good prognosis. Furthermore, LRIG1 expression correlated with HPV status, whereas LRIG2 expression inversely correlated with HPV status. Conclusions: Taken together, the results suggest that LRIG1 immunoreactivity could be a clinically important prognostic marker in HPV-associated oropharyngeal cancer.

Abstract
Patients with cancer of unknown primary (CUP) in the head neck region are generally treated with neck dissection followed by radiotherapy at times combined with chemotherapy, a treatment associated with considerable side effects. Some of these tumors may originate as human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OSCC), with better clinical outcome than head neck squamous cell cancer (HNSCC) in general, and could potentially do well with less treatment. Here, we therefore investigated whether HPV status and p53-expression correlated to clinical outcome in patients with CUP in the head neck region. Fifty metastases were analyzed for presence of HPV DNA, and expression of p16INK4A and p53 and the data were correlated to clinical outcome. Patients with HPV DNA-positive (HPVDNA+) metastases had significantly better 5-year overall survival (OS) compared to those with HPVDNA− metastases (80.0% vs. 36.7%, respectively; P = 0.004), with a similar tendency for disease-free survival (DFS). These survival rates showed excellent concordance with those of HPVDNA+ and HPVDNA− OSCC in Sweden during the same time period, strengthening the hypothesis that HPVDNA+ head and neck CUP may originate from HPVDNA+ OSCC. In addition, having absent/intermediary-low as compared to high expression of p53 correlated to a better prognosis with a 69% as compared to 14% 5-year OS, respectively (P < 0.001), and for DFS the tendency was analogous. In conclusion, both HPV status and p53 expression are valuable prognostic factors in patients with CUP in the head and neck region and should be further explored for clinical use.
