RESUMO
BACKGROUND: Desmoid fibromatosis is a fibroblastic neoplasm driven by aberrations within the WNT pathway, exhibiting mutations in ß-catenin or APC. We review the long-term follow-up of patients in a phase I study treated with an oral gamma secretase inhibitor, PF-03084014. METHODS: PF-03084014 was administered orally at doses ranging from 20 to 330 mg twice daily. Tumor assessments were performed using computed tomography/magnetic resonance imaging (CT/MRI) within 4 weeks of study entry, and every other cycle through cycle 9. After cycle 9, patients were evaluated as clinically indicated. RESULTS: Seven patients with desmoid fibromatosis were treated between December 2009 and December 2016 at the University of Colorado. Five patients (71.4%, 95% confidence interval [CI] 29.0-96.3%) achieved a partial response (PR), with a mean time to achieving response of 11.9 months (95% CI 2.5-21.4 months). All patients who achieved a PR continue to maintain responses between 47.9 and 73+ months. Four patients stopped treatment yet remain free of progression between 11 and 53+ months. One patient had PFS of 42+ months, with a 17% decrease in the target lesion. A biopsy performed at the end of the study showed decreased tumoral cellularity compared with previous biopsies. Effective treatment doses ranged from 80 to 330 mg administered orally twice daily. CONCLUSIONS: PF-03084014 was effective in treating desmoid tumors, with an objective response rate of 71.4% (95% CI 29.0-96.3%) in this small cohort of patients. PF-03084014 exhibits promising activity, even at relatively low doses (80 mg twice daily), with high tolerability leading to prolonged disease control even after therapy discontinuation.

BACKGROUND: Minimal research has explored community dwelling adults' knowledge of the human papillomavirus (HPV) in relation to head and neck cancer (HNC). The purpose of this study was to report on community dwelling adults' knowledge of HPV in relation to infection, symptoms, and the development of HNC. METHODS: Cross-sectional assessment of community-dwelling adults on history of behavioral risk factors for HNC, health literacy, and knowledge regarding HPV in relation to HNC. RESULTS: Of those who completed the measure of health literacy, 17.1% read at or below an 8th grade level. Participants reported a range of history of behaviors putting them at increased risk for HPV and HNC. Respondents answered an average of 67.2% of HPV questions correctly, only one person answered all 15 questions correctly. There were no differences in knowledge of HPV in relation to HNC based upon demographics, suburban versus urban location, health literacy, or cancer history. CONCLUSIONS: Adults reported a range of behaviors associated with an increased risk of HPV transmission but also displayed large gaps in knowledge regarding HPV in relation to HNC.

INTRODUCTION: Despite being the second most common salivary disease in childhood, the aetiology and appropriate management of juvenile recurrent parotitis (JRP) remains uncertain. Consequently patients may be misdiagnosed, or even undergo indeterminate or potentially invasive procedures without benefit. This article reviews the current understanding of the epidemiology and pathophysiology of JRP, and to appraise the management options available. METHODS AND RESULTS: Medline and Google Scholar databases were searched and peer reviewed journal articles assessed. The epidemiology of JRP remains uncertain, and the clinical presentation of JRP can vary widely in frequency and severity. Diagnosis is still largely based on clinical signs and symptoms including parotid swelling, pain and fever. Investigation typically focuses on the exclusion of other diseases and immunodeficiencies, however there are noted typical radiological findings on both ultrasound and magnetic resonance imaging. The ideal management of this condition still remains unclear, however symptoms typically resolve by puberty. Treatment focuses on minimally invasive procedures such as sialography and sialendoscopy to reduce the frequency and severity of acute episodes. CONCLUSIONS: Acute episodes of JRP can occur up to 30 times per year and have a significant impact on the quality of life of an affected child. Consequently a management algorithm is proposed based on the exclusion of other pathology. There is increasing evidence for non-ablative, minimally invasive approaches such as sialography and sialendoscopy to reduce the impact of this disease.

Sarcoma is a broad term for mesenchymal malignancies that arise from soft tissue or bone. Despite classification by histologic subtype, clinical behavior and response to therapy have great variability. Modern genetic sequencing techniques have been able to identify additional genetic variability and subsequently new targeted therapies. In this review, we discuss the current state of STS diagnostics and treatment and explore some of the more promising areas in which progress is being made. We discuss therapies targeting PDGFRα/KIT, ß-Catenin/APC/NOTCH, IDH-1/2 mutations, MDM2 amplifications, EZH2/INI1 expression loss, ALK fusion, and ASPSCR1-TFE3 fusion. We also discuss the progress that has been made within immunotherapies. While soft tissue sarcomas still portend a poor prognosis, these targeted therapies and immunotherapies provide treatment with less toxic side effects.

OBJECTIVES: Evaluate current accepted risk factors for well-differentiated thyroid carcinoma, and develop a predictive model to determine one's risk of malignancy given a thyroid nodule. STUDY DESIGN: Retrospective analysis of 600 patients. SUBJECTS AND METHODS: Patients with benign thyroid nodular disease and with well-differentiated thyroid cancer were randomly selected. Patient, clinical, and investigational data were compared by means of univariate and multivariate regression analyses. RESULTS: Age, regional lymphadenopathy, ipsilateral vocal cord palsy, solid and/or calcified nodules, and an aspiration biopsy being malignant or suspicious predicted for cancer (P < 0.05). Regional lymphadenopathy and vocal cord palsy are perfect predictors of malignancy. Multivariate analysis indicated age, solid and/or calcified nodules, and all fine-needle aspiration biopsy results to be significant in assessing risk (P < 0.05). CONCLUSION: Taking individual risk factors in isolation is not always reliable. Using a predictive model, one can anticipate a patient's risk of malignancy when the diagnosis is unclear.

Background: To identify aberrant promoter methylation of genomic loci encoding microRNA (mgmiR) in head and neck squamous cell carcinoma (HNSCC) and to evaluate a biomarker panel of mgmiRs to improve the diagnostic accuracy of HNSCC in tissues and saliva. Methods: Methylation of promoter regions of mgmiR candidates was initially screened using HNSCC and control cell lines and further selected using HNSCC and control tissues by quantitative methylation-specific PCR (qMS-PCR). We then examined a panel of seven mgmiRs for validation in an expanded cohort including 189 HNSCC and 92 non-HNSCC controls. Saliva from 86 pre-treatment HNSCC patients and 108 non-HNSCC controls was also examined using this panel of seven mgmiRs to assess the potentials of clinical utilization. Results: Among the 315 screened mgmiRs, 12 mgmiRs were significantly increased in HNSCC cell lines compared to control cell lines. Seven out of the 12 mgmiRs, i.e., mgmiR9-1, mgmiR124-1, mgmiR124-2, mgmiR124-3, mgmiR129-2, mgmiR137, and mgmiR148a, were further found to significantly increase in HNSCC tumor tissues compared to control tissues. Using multivariable logistic regression with dichotomized variables, a combination of the seven mgmiRs had sensitivity and specificity of 92.6 and 92.4% in tissues and 76.7 and 86.1% in saliva, respectively. Area under the receiver operating curve for this panel was 0.97 in tissue and 0.93 in saliva. This model was validated by independent bootstrap validation and random forest analysis. Conclusions: mgmiR biomarkers represent a novel and promising screening tool, and the seven-mgmiR panel is able to robustly detect HNSCC in both patient tissue and saliva.

OBJECTIVE: The goal was to monitor the effectiveness of the Coast Guard Yard's lead program by comparing a shipyard period in 1991 to one in 2002-2003. METHODS: Comparisons of airborne lead levels by paint removal techniques, airborne lead levels by welding techniques, and blood lead levels of workers were evaluated by chi2 analysis. RESULTS: Airborne lead levels in paint removal techniques decreased over time for all methods used. Airborne lead levels in welding techniques decreased over time for all methods used. Blood lead levels of the high-risk group revealed a 2-fold reduction (prevalence rate ratio = 8.3; 95% confidence interval, 3.7-18.6) and in the low-risk group revealed a 1.6-fold reduction (prevalence rate ratio = 6.2; 95% confidence interval, 0.86-44.7). CONCLUSION: The Coast Guard Yard runs an effective lead program that exceeds the national Healthy People 2010 goal for lead. The results validate the Coast Guard Yard's use of air-line respirators and lead-free paint on all vessels.

PURPOSE OF REVIEW: Perforator flaps are increasingly being used to reconstruct head and neck defects. They offer several advantages over nonperforator-based flaps with lower donor site morbidity and a versatile range of reconstructive options. The anterolateral thigh flap is well established in the head and neck and is a good example of a reliable perforator free flap. With the increasing use of both free and regional perforator-based flaps, it is timely to review their anatomy, clinical applications, and role in head and neck reconstruction. We also discuss increasingly popular perforator flaps such as the submental flap for the head and neck. RECENT FINDINGS: The anterolateral thigh flap is now commonly used to reconstruct a wide variety of head and neck defects. The submental flap fills a niche role for reconstruction of intraoral defects. SUMMARY: Perforator flaps are now mainstream reconstructive options in the head and neck surgeon's armamentarium.

The incidence of chronic otitis media with effusion (COME) after radiotherapy for nasopharyngeal or sinonasal tumors is relatively high. It is often a difficult-to-treat problem in these patients. In this retrospective study, we sought to describe the clinical course of COME in 51 patients-33 men and 18 women, aged 39 to 90 years (mean: 58.9 ± 15)-who had been referred to the Henry Ford Health System in Detroit between 2001 and 2011 for management of a tumor that had involved either the nasopharyngeal area or the sinonasal area. The median length of follow-up from the time of cancer diagnosis was 32 months. Of the 51 patients, 23 (45.1%) developed COME before, during, or after radiation therapy. Of these 23 patients, 13 (56.5%) did not experience any improvement after treatment with various combinations of therapies, including myringotomy, tympanostomy tube placement, otic drops, oral antibiotics, and corticosteroid nasal sprays. No patient- or tumor-specific factors were found to be significantly associated with the incidence of COME after irradiation to the sinonasal area. Older age and squamous cell tumor pathology were found to be significant factors for the resolution of COME after it had developed, whereas treatments with tympanostomy tubes and ear drops were not. Because of the high incidence of COME after radiotherapy and the high rate of COME's failure to resolve after tympanostomy tube insertion, we suggest that these patients require an alternative treatment.

OBJECTIVES: Distant metastases from thyroid cancer are uncommon and have a variable prognosis. We present a series of patients with distant metastases to determine which patients are at risk of developing distant disease and to examine the significant prognostic variables. STUDY DESIGN: Retrospective chart review of 30 patients with distant metastases compared with 633 controls from the Mount Sinai Thyroid Cancer Database and literature review. METHODS: The prevalence of distant metastases was 4.5%, and median follow-up of survivors was 12.7 years. Histologic type was Hurthle cell carcinoma in 3, follicular in 3, papillary in 19, and 5 patients had focal anaplasia either in the primary site or regional metastases. Predictors for distant metastases, locoregional control, and survival were analyzed. RESULTS: Cumulative survival for patients with distant metastases was 49.5% at 10 years and 12.9% at 20 years. Site of metastases was lung in 26, bone in 11 and brain in 1 patient, with 8 patients having multiple sites. The median time to diagnosis of distant metastases was 3 months. Variables that predicted for development of distant disease were male sex, age, size, extrathyroidal extension, regional metastases, and elevated thyroglobulin. Survival in patients without distant disease was significantly better than those with distant metastases (P < .001). Variables that predicted poor outcome in patients with distant metastases on analysis were age greater than 45 years (P = .003) and histologic type of thyroid cancer (P = .009). CONCLUSION: Although patients with thyroid cancer and distant metastases may live prolonged periods with disease, it does significantly impact on patient survival. Age remains an important variable in both predicting for development of distant metastases and also influences long-term survival in patients with existing distant metastases.

OBJECTIVES: Familial non-medullary thyroid cancer (FNMTC) is a newly recognized disease entity and can be distinguished from the more common sporadic non-medullary thyroid cancer. The purpose of this study was to determine some of the potential distinguishing features of FNMTC. STUDY DESIGN: Retrospective association study and matched-case control study. METHODS: Five hundred forty-three cases of well-differentiated follicular origin thyroid cancers were identified and collected in a database. Among this population, 24 cases of FNMTC were identified. A case of FNMTC was defined as a patient with the following two criteria: a well-differentiated follicular origin thyroid cancer and at least one first-degree relative with a well-differentiated epithelial origin thyroid cancer. The unmatched sporadic and FNMTC groups were compared using t test, Phi test, Cramer V test, and Pearson and Spearman correlation tests. Twenty-four FNMTC cases were matched to 24 sporadic cases based on age, gender, stage of disease at presentation, and tumor size. Clinicopathologic features, management, and outcome were analyzed statistically using a matched-proportional z test. Disease-free survival and disease-specific survival were analyzed using log-rank test and the Kaplan-Meier function. A P-value less than .05 was considered statistically significant. RESULTS: : There was no significant difference in ionizing radiation exposure, disease multifocality, surgical management, or recurrence between the sporadic and FNMTC patients. Although FNMTC patients tend to have improved disease-free survival and disease-specific survival, the difference was not significant at the 5% level. CONCLUSION: Although FNMTC is characterized by strong family history, these patients do not tend to have worse prognosis.

OBJECTIVES/HYPOTHESIS: The objective was to compare the rate and site of recurrences in patients with well-differentiated thyroid carcinoma who underwent a central compartment dissection, a posterolateral neck dissection, or a combination of both procedures. STUDY DESIGN: Retrospective chart review. METHODS: The charts of 522 consecutive patients with well-differentiated thyroid carcinoma were reviewed, and 74 patients who had undergone a neck dissection were identified. The rates of recurrence in three sites were noted: the central compartment nodes (levels VI, superior mediastinum), posterolateral compartment neck nodes (levels II-V), and distant sites. These rates were compared in patients who underwent a central compartment dissection (level VI, superior mediastinum) and in patients who underwent a posterolateral neck dissection (levels II-V). RESULTS: Six patients underwent only a central compartment dissection, 47 patients had only a posterolateral neck dissection, and 21 patients had both a central compartment and a posterolateral neck dissection. In these three groups there were zero, two, and two central compartment node recurrences; two, nine, and seven posterolateral neck recurrences; and zero, two, and three distant recurrences, respectively. There were no significant differences in the rate of recurrence in any of the three sites examined between any of the three treatment groups (Fisher's Exact test, all P values >.20). CONCLUSION: In patients with well-differentiated thyroid carcinoma, dissection of only the central or posterolateral compartments of the neck with clinical or radiographic evidence of disease is advocated.

OBJECTIVE: To determine the relationship between stimulated serum thyroglobulin levels (taken 3 months after total thyroidectomy) and tumor stage and recurrence in patients with well-differentiated thyroid carcinoma. STUDY DESIGN: Retrospective chart review in a tertiary care institution. METHODS: Two hundred thirteen consecutive patients with well differentiated thyroid carcinoma treated between 1983 and 1998 were identified. Data were collected on clinicopathological variables, stimulated serum thyroglobulin levels obtained 3 months after total thyroidectomy prior to 131I therapy and recurrence. RESULTS: A high postoperative thyroglobulin level was significantly associated with advanced-stage disease at presentation (P =.005, Kruskall-Wallis) but not with any of the other clinicopathological variables. Patients with a thyroglobulin level greater than 20 pmol/L had a significantly increased risk of disease recurrence on univariate analysis (n = 213 [P =.0001, log rank test]), and in the Cox proportional-hazards model, both advanced tumor stage (P =.001, relative hazard, 3.4 [95% confidence interval [CI]: 2.4-4.9]) and a thyroglobulin level greater than 20 pmol/L (P =.001, relative hazard, 5.1 [95% CI: 2.0-13.1]) were significant predictors of recurrence. No other variables significantly altered the hazards model. CONCLUSIONS: Advanced tumor stage at diagnosis and a stimulated thyroglobulin level greater than 20 pmol/L taken 3 months after total thyroidectomy were independent predictors of disease recurrence. Patients with a thyroglobulin level greater than 20 pmol/L are at increased risk of recurrence and may be candidates for more intensive follow-up or additional treatment.

OBJECTIVE: To examine the relationship between lymphatic vessel density and clinical and pathological variables in patients with well-differentiated papillary thyroid carcinoma. SUBJECTS: Clinical information was retrieved on 109 previously untreated patients with well-differentiated papillary thyroid carcinoma treated with total thyroidectomy and postoperative iodine I 131 ablation. Median follow-up was 38 months. DESIGN: Archived tissue specimens were sectioned and stained with hematoxylin-eosin and anti-LYVE-1 antibody, a highly specific marker for lymphatic endothelium. The size of the tumor and its multifocality were noted and lymphatic vessel density was measured by means of Chalkley point counting. RESULTS: Numerous intratumoral lymphatics were seen in papillary thyroid carcinoma. There was a highly significant association between the presence of intratumoral lymphatics and the presence of neck node metastases (P<.001). There was also a significant association with male sex (P =.03) and the presence of multifocal disease (P =.05). The presence of intratumoral lymphatics remained significantly associated with the presence of nodal metastases at presentation (P =.003) on multivariate analysis. Intratumoral lymphatics were not a significant predictor of tumor recurrence (P =.42, log-rank test). CONCLUSIONS: The development of intratumoral lymphatics in well-differentiated papillary thyroid carcinoma appears to be associated with the spread of tumor to regional lymph nodes. The antimetastatic potential of targeting these lymphatics may be of potential therapeutic benefit in the future.

BACKGROUND: Patients with advanced cancers of the larynx and hypopharynx have been treated with total laryngectomy at the Department of Head and Neck Surgery, Royal Prince Alfred Hospital, Sydney in the past. Increasingly, these patients are being managed with organ-sparing protocols using chemo-therapy and radiotherapy. The aim of the present study was to review complication, recurrence and survival rates following total laryngectomy. METHODS: Patients who had total laryngectomy for squamous carcinomas of the larynx or hypopharynx between 1987 and 1998 and whose clinicopathological data had been prospectively accessioned onto the computerized database of the Department of Head and Neck Surgery, Royal Prince Alfred Hospital, were reviewed. Patients whose laryngectomy was a salvage procedure for failed previous treatment were included. RESULTS: A total of 147 patients met the inclusion criteria for the study, including 128 men and 19 women with a median age of 63 years. Primary cancers involved the larynx in 90 patients and hypopharynx in 57. There were 30 patients who had recurrent (n = 24) or persistent disease (n = 6) after previous treatment with radiotherapy (26 larynx cases and four hypopharynx cases). Pharyngo-cutaneous fistulas occurred in 26 cases (17.7%) and, using multivariate analysis, the incidence did not correlate with T stage, previous treatment or concomitant neck dissection. Local control rates were 86% for the larynx and 77% for the hypo-pharynx groups and neck control was 84% and 75%, respectively. Five-year survival for the larynx cancer group was 67% and this was significantly influenced by T stage and clinical and pathological N stage. Survival in the hypopharynx group was 37% at 5 years and this did not significantly correlate with T or N stage. There was a non-significant trend to improved survival among previously treated patients whose laryngectomy was a salvage procedure. CONCLUSION: Patients with cancer of the larynx had a significantly better survival following total laryngectomy than patients with hypopharyngeal cancer. Those whose laryngectomy was carried out as a salvage procedure following failed previous treatment did not have a worse outcome than previously untreated patients.

We report a 38-year-old woman with a malignant catecholamine-secreting vagal paraganglioma. In the preceding year she had intermittent severe frontoparietal headaches. While she was receiving radiotherapy (35 Gy in 15 fractions) she developed palpitations, which steadily worsened over the following three years. A repeat CT scan showed no change in the size of the tumor. Urinary catecholamines were elevated and a MIBG scan showed increased uptake in the region of the vagal paraganglioma. She underwent near total resection of her tumor via a Fisch type C approach. Pathological examination showed a paraganglioma with metastasis involving a cervical lymph node. The palpitations and headaches resolved completely after surgery. This report and other published case reports suggest that catecholamine secretion from head and neck paragangliomas does not appear to respond to radiotherapy. Patients with cardiovascular symptoms from catecholamine-secreting paragangliomas are best managed surgically.
RESUMO
OBJECTIVES: To assess the incidence, treatment methods, and outcomes of oropharyngeal squamous cell carcinoma (OPSCC) in patients younger than 45 years. STUDY DESIGN: Retrospective population based. SETTING: Surveillance Epidemiology End Results (SEER) 9 database. SUBJECTS AND METHODS: The SEER 9 database was queried from 1973 to 2009 for OPSCC patients <45 years of age. RESULTS: There were 1603 patients with OPSCC younger than 45 years. The incidence in patients between 36 and 44 years increased from 0.79 to 1.39 (per 100,000). In the same time period, there was an increase in the rate from 0.20 to 0.42 in whites and a decrease in the rate in African American (AA) patients from 0.67 to 0.32. The proportion of grade III/IV tumors also steadily increased from 28% in 1973 to 1979 to 43% in 2000 to 2009 (P < .0001). Surgery alone was performed in 220 patients (13.72%) and in combination with radiation therapy in 734 patients (45.79%). Five-year survival for the study cohort is 54%. Compared with white patients, AA patients had worse survival (P < .0001). Patients who had surgery, either alone (localized stage patients) or in combination with radiation, had the highest 5-year survival followed by those who had radiation. CONCLUSIONS: There was an increase in OPSCC in the study patients within the past 4 decades, particularly in those aged 36 to 44 years. Interestingly, the incidence in whites increased and in AA patients it decreased. It is important to note that most of these patients were treated with surgery, either alone or with radiation therapy. The rising incidence within recent decades is thought to be related to human papillomavirus transmission and changes in sexual practices.

Objective. To evaluate factors that influence gastrostomy tube (g-tube) use after transoral robotic surgery (TORS) for oropharyngeal (OP) cancer. Study Design/Methods. Retrospective review of TORS patients with OP cancer. G-tube presence was recorded before and after surgery at followup. Kaplan-Meier and Cox hazards model evaluated effects of early (T1 and T2) and advanced (T3, T4) disease, adjuvant therapy, and free flap reconstruction on g-tube use. Results. Sixteen patients had tonsillar cancer and 13 tongue base cancer. Of 22 patients who underwent TORS as primary therapy, 17 had T1 T2 stage and five T3 T4 stage. Seven underwent salvage therapy (four T1 T2 and three T3 T4). Nine underwent robotic-assisted inset free flap reconstruction. Seventeen received adjuvant therapy. Four groups were compared: primary early disease (PED) T1 and T2 tumors, primary early disease with adjunctive therapy (PEDAT), primary advanced disease (PAD) T3 and T4 tumors, and salvage therapy. Within the first year of treatment, 0% PED, 44% PEDAT, 40% PAD, and 57% salvage patients required a g-tube. Fourteen patients had a temporary nasoenteric tube (48.3%) postoperatively, and 10 required a g-tube (34.5%) within the first year. Four of 22 (18.2%) with TORS as primary treatment were g-tube dependent at one year and had received adjuvant therapy. Conclusion. PED can be managed without a g-tube after TORS. Similar feeding tube rates were found for PEDAT and PAD patients. Salvage patients have a high rate of g-tube need after TORS.
RESUMO
IMPORTANCE: The increasing number of elderly and comorbid patients undergoing surgical procedures raises interest in better identifying patients at increased risk of morbidity and mortality, independent of age. Frailty has been identified as a predictor of surgical complications. OBJECTIVE: To establish the implications of frailty as a predictor of morbidity and mortality in inpatient otolaryngologic operations. DESIGN: Retrospective review of medical records. SETTING: National Surgical Quality Improvement Program (NSQIP) participating hospitals. PATIENTS: NSQIP participant use files were used to identify 6727 inpatients who underwent operations performed by surgeons specializing in otolaryngology between 2005 and 2010. The study sample was 50.3% male and 10.2% African American, with a mean (range) age of 54.7 (16-90) years. MAIN OUTCOMES AND MEASURES: A previously described modified frailty index (mFI) was calculated on the basis of NSQIP variables. The effect of increasing frailty on morbidity and mortality was evaluated using univariate analysis. Multivariate logistic regression was used to compare mFI with age, ASA, and wound classification. RESULTS The mean (range) mFI was 0.07 (0-0.73). As the mFI increased from 0 (no frailty-associated variables) to 0.45 (5 of 11) or higher, mortality risk increased from 0.2% to 11.9%. The risk of Clavien-Dindo grade IV complications increased from 1.2% to 26.2%. The risk of all complications increased from 9.5% to 40.5%. All results were significant at P < .001. In a multivariate logistic regression model to predict mortality or serious complication, mFI became the dominant significant predictor. CONCLUSIONS AND RELEVANCE: The mFI is significantly associated with morbidity and mortality in this retrospective survey. Additional study with prospective analysis and external validation is needed. The mFI may provide an improved understanding of preoperative risk, which would facilitate perioperative optimization, risk stratification, and counseling related to outcomes.

OBJECTIVE: The goal was to determine the prevalence of high-risk HPV16 using saliva in a screening population in Detroit, Michigan. MATERIALS AND METHODS: Real-time quantitative polymerase chain reaction was applied to detect HPV16 in saliva DNA from 349 screening subjects without head and neck cancer (HNC), 156 with HNC, and 19 controls. Cut points for human papilloma virus (HPV) positivity were >0 and >0.001 copy/cell. Proportions were compared between groups using exact χ(2) or Fisher exact tests (P < .05). RESULTS: At a cut point >0, each group had an overall HPV prevalence of more than 5%, with a higher prevalence of 30.8% in the HNC patient group. At a cut point >0.001, the prevalence was lower: 0% in the control, 1.2% in the screening, and 16.7% in the HNC group. In the latter, for both cut points, HPV prevalence was different across sites (<0.001) and significantly higher in the oropharynx than larynx or site as other after Hochberg's adjustment. At >0, women in the screening group had a higher prevalence of HPV than did men (P = .010), and at >0.001, the prevalence was higher for men in the HNC group than for women (P = .035). In the screening group, at >0, only African Americans had a higher prevalence than Caucasian Americans (P = .025). CONCLUSIONS: In the screening group, a 6.9% and 1.2% screening rate was noted at cut points >0 and >0.001, respectively. The results provide data to inform public health considerations of the feasibility of saliva as a screening tool in at-risk populations with the long-term goal of prophylactic vaccination against oral HPV.
