ImportanceCirculating tumor tissue–modified viral (TTMV) human papillomavirus (HPV) DNA is a dynamic, clinically relevant biomarker for HPV-positive oropharyngeal squamous cell carcinoma. Reasons for its wide pretreatment interpatient variability are not well understood.ObjectiveTo characterize clinicopathologic factors associated with TTMV HPV DNA.Design, Setting, and ParticipantsThis cross-sectional study included patients evaluated for HPV-positive oropharyngeal squamous cell carcinoma at Dana-Farber Cancer Institute in Boston, Massachusetts, between December 2019 and January 2022 and who were undergoing curative-intent treatment.ExposuresClinicopathologic characteristics including demographic variables, tumor and nodal staging, HPV genotype, and imaging findings.Main Outcomes and MeasuresPretreatment circulating TTMV HPV DNA from 5 genotypes (16, 18, 31, 33, and 35) assessed using a commercially available digital droplet polymerase chain reaction–based assay, considered as either detectable/undetectable or a continuous score (fragments/mL).ResultsAmong 110 included patients, 96 were men (87%) and 104 were White (95%), with a mean (SD) age of 62.2 (9.4) years. Circulating TTMV HPV DNA was detected in 98 patients (89%), with a median (IQR) score of 315 (47-2686) fragments/mL (range, 0-60 061 fragments/mL). Most detectable TTMV HPV DNA was genotype 16 (n = 86 [88%]), while 12 patients (12%) harbored other genotypes. Circulating TTMV HPV DNA detection was most strongly associated with clinical N stage. Although few patients had clinical stage N0 disease, only 4 of these 11 patients (36%) had detectable DNA compared with 94 of 99 patients (95%) with clinical stage N1 to N3 disease (proportion difference, 59%; 95% CI, 30%-87%). Among patients with undetectable TTMV HPV DNA, more than half (7 of 12 [58%]) had clinical stage N0 disease. The TTMV HPV DNA prevalence and score increased with progressively higher clinical nodal stage, diameter of largest lymph node, and higher nodal maximum standardized uptake value on positron emission tomography/computed tomography. In multivariable analysis, clinical nodal stage and nodal maximum standardized uptake value were each strongly associated with TTMV HPV DNA score. Among 27 surgically treated patients, more patients with than without lymphovascular invasion had detectable TTMV HPV DNA (12 of 12 [100%] vs 9 of 15 [60%]).Conclusions and RelevanceIn this cross-sectional study, circulating TTMV HPV DNA was statistically significantly associated with nodal disease at HPV-positive OPSCC diagnosis. The few patients with undetectable levels had predominantly clinical stage N0 disease, suggesting assay sensitivity for diagnostic purposes may be lower among patients without cervical lymphadenopathy. Mechanisms underlying this association, and the use of this biomarker for surveillance of patients with undetectable baseline values, warrant further investigation.
In January 2021, the Centers for Medicare & Medicaid Services began requiring hospitals to publish price transparency files listing all prices negotiated with payers. We performed a cross-sectional analysis of payer-negotiated prices for commonly performed outpatient otolaryngology surgery at all hospitals scored by the US News & World Report in otolaryngology. We compared prices among hospitals (across-center ratios) and among payers at the same hospital (within-center ratios). Price disclosure rates were low overall for otolaryngologic surgery (maximum, 26.7% for bronchoscopy). Across-center ratios ranged from 3.5 (adjacent tissue transfer/rearrangement <10 cm2; raw median price range, $1384-$7047) to 18.6 (cochlear implant placement; raw median price range, $2417-$60,255). Median within-center ratios ranged between 2.7 (intraoperative navigation) and 5.4 (total thyroidectomy). Although price variation may signal opportunities for cost savings, patients may have limited ability to comparison shop due to hospital nondisclosure. Further investigation is necessary to examine the factors affecting price variation for otolaryngologic procedures.
Objectives: Hospital prices vary substantially for myringotomy with tympanostomy tube placement (M&T) and adenotonsillectomy (T&A). The Centers for Medicare and Medicaid Services recently implemented hospital price transparency requirements to help families make financially informed decisions about where to seek care. We sought to determine price availability and the extent of price variation for these procedures.Methods: We performed a cross-sectional analysis of the Turquoise Health Hospital Rates Data Platform, which extracts prices for facility fees from publicly available hospital chargemasters. We determined the proportion of hospitals serving pediatric patients that published payer-specific prices for M&T and T&A. We additionally characterized the extent of variation in payer-specific prices both across and within hospitals.Results: Approximately 40% (n = 909 of 2,266 hospitals) serving pediatric patients disclosed prices for M&T or T&A. Among disclosing hospitals, across-center ratios (adjusted for Medicare hospital wage indices) ranged from 11.0 (M&T; 10th percentile adjusted median price: $536.80 versus 90th percentile adjusted median price: $5,929.93) to 23.4 (revision adenoidectomy age >12 years; 10th percentile: $393.82 versus 90th percentile: $9,209.88). Median within-center price ratios for procedures ranged from 2.2 to 2.7, indicating that some private payers reimbursed the same hospital more than twice as much as other payers for the same procedure. Conclusion:The majority of hospitals serving pediatric patients were non-compliant with federal requirements to disclose prices for M&T and T&A. Among disclosing hospitals, there was wide variation in payer-specific prices between and within institutions. Further research is necessary to understand whether disclosure of prices will enable families to make more financially informed decisions.
This cross-sectional study evaluates demographic characteristics, surgical characteristics, and audiometric data associated with closure of the air-bone gap to less than 10 dB or 15 dB.
