Human papillomavirus-active head and neck cancer and ethnic health disparities.

ABSTRACT: Mortality for black males with head and neck squamous cell carcinoma (HNSCC) is twice that of white males or females. Human papillomavirus (HPV)-active HNSCC, defined by the concurrent presence of high-risk type HPV DNA and host cell p16(INK4a) expression, is associated with decreased mortality. We hypothesized that prevalence of this HPV-active disease class would be lower in black HNSCC patients compared to white patients.Multi-institutional retrospective cohort analysis.Real-time polymerase chain reaction was used to evaluate for high-risk HPV DNA presence. Immunohistochemistry for p16(INK4a) protein was used as a surrogate marker for HPV oncoprotein activity. Patients were classified as HPV-negative (HPV DNA-negative, p16(INK4a) low), HPV-inactive (HPV DNA-positive, p16(INK4a) low), and HPV-active (HPV DNA-positive, p16(INK4a) high). Overall survival and recurrence rates were compared by Fisher exact test and Kaplan-Meier analysis.There were 140 patients with HNSCC who met inclusion criteria. Self-reported ethnicity was white (115), black (25), and other (0). Amplifiable DNA was recovered from 102/140 patients. The presence of HPV DNA and the level of p16(INK4a) expression were determined, and the results were used to classify these patients as HPV-negative (44), HPV-inactive (33), and HPV-active (25). Patients with HPV-active HNSCC had improved overall 5-year survival (59.7%) compared to HPV-negative and HPV-inactive patients (16.9%) (P = .003). Black patients were less likely to have HPV-active disease (0%) compared to white patients (21%) (P = .017).The favorable HPV-active disease class is less common in black than in white patients with HNSCC, which appears to partially explain observed ethnic health disparities.

Project description:Detection of human papillomavirus (HPV) in head and neck cancer has therapeutic implications. In situ hybridization and immunohistochemistry for p16 are used by surgical pathologists. We compared the sensitivity and specificity of three popular commercial tests for HPV detection in head and neck squamous cell carcinomas with a 'gold standard' HPV PCR assay. A total of 110 prospectively collected, formalin-fixed tumor specimens were compiled onto tissue microarrays and tested for HPV DNA by in situ hybridization with two probe sets, a biotinylated probe for high-risk (HR) HPV types 16/18 (Dako, CA, USA) and a probe cocktail for 16/18, plus 10 additional HR types (Ventana, AZ, USA). The p16(INK4) expression was also assessed using a Pharmingen immunohistochemistry antibody (BD Biosciences, CA, USA). Tissue microarrays were stained and scored at expert laboratories. HPV DNA was detected by MY09/11-PCR, using Gold AmpliTaq and dot-blot hybridization on matched-fresh frozen specimens in a research laboratory. HPV 16 E6 and E7-RNA expression was also measured using RT-PCR. Test performance was assessed by a receiver operating characteristic analysis. HR-HPV DNA types 16, 18 and 35 were detected by MY-PCR in 28% of tumors, with the majority (97%) testing positive for type 16. Compared with MY-PCR, the sensitivity and specificity for HR-HPV DNA detection with Dako in situ hybridization was 21% (95% confidence interval (CI): 7-42) and 100% (95% CI: 93-100), respectively. Corresponding test results by Ventana in situ hybridization were 59% (95% CI: 39-78) and 58% (95% CI: 45-71), respectively. The p16 immunohistochemistry performed better overall than Dako (P=0.042) and Ventana (P=0.055), with a sensitivity of 52% (95% CI: 32-71) and specificity of 93% (95% CI: 84-98). Compared with a gold standard HPV-PCR assay, HPV detection by in situ hybridization was less accurate for head and neck squamous cell carcinoma on tissue microarrays than p16 immunohistochemistry. Further testing is warranted before these assays should be recommended for clinical HPV detection.

Project description:BackgroundPatients who travel a long distance (≥50 miles) for cancer care have improved outcomes. However, to the authors' knowledge, the prevalence of long travel distances for treatment by patients with head and neck squamous cell carcinoma (HNSCC), and the effect of travel distance on overall survival (OS), remains unknown.MethodsThe authors used the National Cancer Data base from 2004 through 2013 to identify patients with HNSCC undergoing definitive treatment. Travel distance for treatment was categorized as short (<12.5 miles), intermediate (12.5-49.9 miles), and long (50-249.9 miles). The primary outcome, OS, was evaluated using Cox shared-frailty modeling. A secondary outcome, factors associated with intermediate and long travel distances, was evaluated using multivariable hierarchical logistic regression.ResultsAmong 118,000 patients with HNSCC, 62,753 (53.2%), 40,644 (34.4%), and 14,603 (12.4%) patients, respectively, traveled short, intermediate, and long distances for treatment. After adjusting for relevant covariates, long travel distance was associated with treatment at academic and high-volume centers. Patients of black race, of Hispanic ethnicity, with Medicaid insurance, and who were treated with nonsurgical treatment were less likely to travel long distances for treatment (P<.001). Traveling a long distance for treatment was associated with improved OS on multivariable analysis (adjusted hazard ratio, 0.93; 95% confidence interval, 0.89-0.96) compared with a short distance.ConclusionsTraveling a long distance for HNSCC treatment is associated with improved survival, especially for patients receiving nonsurgical management. Racial and ethnic disparities in travel for HNSCC treatment exist. As regionalization of care continues, future work should identify and address reasons for racial and ethnic disparities in travel that may prevent access to care at high-volume facilities.

Project description:Importance:Prospective studies are needed to examine the temporal relationship between oral human papillomavirus (HPV) detection and risk of head and neck squamous cell carcinoma (HNSCC). Moreover, the oral cavity contains a wide spectrum of ?-, ?-, and ?-HPV types, but their association with risk of HNSCC is unknown. Objective:To prospectively examine associations between ?-, ?-, and ?-HPV detection in the oral cavity and incident HNSCC. Design:A nested case-control study was carried out among 96?650 participants, cancer free at baseline, with available mouthwash samples in 2 prospective cohort studies: (1) the American Cancer Society Cancer Prevention Study II Nutrition Cohort and (2) the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. Incident cases of HNSCC (n?=?132) were identified during an average 3.9 years of follow-up in both cohorts. Three controls per case (n?=?396) were selected through incidence density sampling and matched on age, sex, race/ethnicity, and time since mouthwash collection. Methods:Through a next-generation sequencing assay, DNA from ?-, ?-, and ?-HPV types were detected. Conditional logistic regression models were used to estimate odds ratios (ORs) and 95% CIs, adjusting for smoking history, alcohol consumption, and detection of HPV-16 for ?- and ?-HPVs. Main Outcomes and Measures:Incident HNSCC, which includes cancers of the oropharynx, oral cavity, and larynx. Results:A total of 132 participants developed HNSCC during the follow-up period (103 men and 29 women; average age at baseline, 66.5 years). Oral HPV-16 detection was associated with incident HNSCC (OR, 7.1; 95% CI, 2.2-22.6), with positive association for oropharyngeal SCC (OR, 22.4; 95% CI, 1.8-276.7), but not for oral cavity (OR, 4.5; 95% CI, 0.6-34.7) or laryngeal SCCs (OR, 0.11; 95% CI, 0.01-834.80). Detection of ?1-HPV-5 and ?2-HPV-38 types, as well as ?-11 and ?-12 species, had ORs for HNSCC that ranged from 2.64 to 5.45 (P?<?.01 for all comparisons). Detection of ?1-HPV-5 type was associated with oropharyngeal (OR, 7.42; 95% CI, 0.98-56.82; P?=?.054), oral cavity (OR, 5.34; 95% CI, 1.51-18.80; P?=?.01), and laryngeal SCCs (OR, 2.71; 95% CI, 1.00-7.43; P?=?.05), whereas ?11- and ?12-HPV species were associated with both oral cavity (OR, 7.47; 95% CI, 1.21-46.17; P?=?.03; and OR, 6.71; 95% CI, 1.47-30.75; P?=?.01, respectively) and laryngeal SCCs (OR, 7.49; 95% CI, 1.10-51.04; P?=?.04 and OR, 5.31; 95% CI, 1.13-24.95; P?=?.03, respectively). Conclusions and Relevance:This study demonstrates that HPV-16 detection precedes the incidence of oropharyngeal SCC. Associations of other HPVs, including ?11- and ?12-HPV species and ?1-HPV-5 type suggest a broader role for HPVs in HNSCC etiology.
