RESUMO
BACKGROUND: Human papillomavirus (HPV)+â oropharynx cancer (OPC) has a more favorable prognosis than HPV-negative disease, but the impact of specific HPV genotype and phylogenic clade on patient outcomes is not well understood and has profound implications for treatment de-intensification. METHODS: The objective of this single-institution cohort study was to investigate the association of HPV genotype (16 vs high-risk non-16) and clade (A9 vs A7) with OPC outcomes. The primary endpoints were overall survival (OS) and event-free survival (EFS) in patients with M0 disease treated with curative intent. RESULTS: The cohort included 598 patients (87% HPV16, 98% A9). Compared to those with HPV16 OPC, individuals with non-HPV16 OPC had a higher age, comorbidity index, and proportion of non-whites, HIV+ patients, T4 tumors, and stage IV disease (AJCC 7th edition). Non-HPV16 genotype was associated with worse OS in univariate (HRâ =â 2.17, 95% CI, 1.24-3.80, Pâ =â .0066), but not in multivariate analysis (HRadjâ =â 0.84, 95% CI, 0.43-1.62, Pâ =â .5921). A7 clade was associated with worse OS in univariate (HRâ =â 4.42, 95% CI, 1.60-12.30, Pâ =â .0041), but not in multivariate analysis (HRadjâ =â 2.39, 95% CI, 0.57-9.99, Pâ =â .2325). Neither HPV genotype (HRâ =â 1.60, 95% CI, 0.99-2.60, Pâ =â .0566) nor phylogenic clade (HRâ =â 2.47, 95% CI, 0.91-6.72, Pâ =â .0761) was associated with EFS. CONCLUSION: Non-HPV16 genotype and A7 clade were associated with worse OS and trended toward worse EFS in univariate analyses. The survival differences were more pronounced by phylogenic clade than by HPV16 status, suggesting that the former may be a more useful classification for future studies. However, neither HPV16 status nor phylogenic clade was prognostic when adjusting for patient and tumor covariates, raising the question as to whether possible differences in outcomes are related to distinct clinical profiles rather than inherent viral properties.
RESUMO
PURPOSE: This study compared treatment and outcomes for patients with HPV-positive oropharyngeal squamous cell carcinoma (OPSCC) based on their travel distance to treatment facility. MATERIALS AND METHODS: Patients with cT1-4, N0-3, M0 HPV-positive OPSCC in the National Cancer Database from 2010 to 2019 were identified and split into four quartiles based on distance to facility, with quartile 4 representing patients with furthest travel distances. Multivariable-adjusted logistic regression and Cox proportional hazards modeling were used to analyze the primary outcome of treatment received, and secondary outcomes of clinical stage, overall survival, surgical approach (i.e., TORS versus other), and 30-day surgical readmissions. RESULTS: 17,207 patients with HPV-positive OPSCC were evenly distributed into four quartiles. Compared to patients in quartile 1, patients in quartile 4 were 40 % less likely to receive radiation versus surgery (OR = 0.60; 95 % CI = 0.54-0.66). Among the patients who received surgery, quartile 4 had a higher odds of receiving TORS treatment compared to quartile 1 (4v1: OR = 2.38; 95 % CI = 2.05-2.77), quartile 2 (4v2: OR = 2.31, 95 % CI = 2.00-2.66), and quartile 3 (4v3: OR = 1.75; 95 % CI = 1.54-1.99). Quartile 4 had a decreased odds of mortality compared to Quartile 1 (4v1: OR = 0.87; 95 % CI = 0.79-0.97). There were no differences among the quartiles in presenting stage and 30-day readmissions. CONCLUSIONS: This study found that patients with furthest travel distance to facility were more often treated surgically over non-surgical management, with TORS over open surgery, and had better overall survival. These findings highlight potential disparities in access to care for patients with HPV-positive OPSCC.

PURPOSE: To compare human papillomavirus (HPV) testing, prevalence, and association with prognosis between head and neck squamous cell carcinoma (HNSCC) subsites. MATERIALS AND METHODS: This study utilized the National Cancer Database (NCDB) to identify patients diagnosed with HNSCC between 2010 and 2017. Rates of HPV testing, HPV-positivity, and changes in these rates over time were measured by subsite. The impact of HPV-positivity on overall survival across six head and neck subsites was assessed using multivariable-adjusted Cox proportional hazards analysis. RESULTS: A total of 121,550 patients were included. Of this cohort, 87,575 (72.1%) were tested for HPV, with the oropharynx (55,049/64,158; 85.8%) displaying the highest rates of testing and the sinonasal tract (1519/2853; 53.2%) displaying the lowest testing rates. Of the 86,136 with a definitive result, 46,878 (54.4%) were HPV-positive, with the oropharynx (40,313/54,205; 74.4%) displaying the highest rates of HPV-positivity and the oral cavity (1818/11,505; 15.8%) displaying the lowest. HPV-positive malignancy was associated with significantly improved adjusted overall survival in the oropharynx (HR = 0.42 [95% CI: 0.43-0.47]), oral cavity (HR = 0.86 [95% CI: 0.79-0.95]), sinonasal tract (HR = 0.63 [95% CI: 0.48-0.83]), larynx (HR = 0.78 [95% CI: 0.71-0.87]), and hypopharynx (HR = 0.56 [95% CI: 0.48-0.66]), but not the nasopharynx (HR = 0.93 [95% CI: 0.77-1.14]). CONCLUSION: HPV testing rates were significantly lower in non-oropharyngeal subsites. This is relevant as HPV-associated disease displayed significantly improved overall survival in both the oropharynx and four of five non-oropharyngeal subsites. While validation with prospective studies is necessary, these findings may warrant HPV testing in all HNSCC subsites.

BACKGROUND: In 2018, the National Comprehensive Cancer Network treatment guidelines began recommending the use of neck dissection during surgical management of stage I-II supraglottic laryngeal squamous cell carcinoma (LSCC). METHODS: Trends and factors associated with the use of neck dissection during larynx-preserving surgery for patients with cT1-2, N0, M0 supraglottic LSCC in the National Cancer Database (2004-2020) were evaluated using multivariable-adjusted logistic regression. RESULTS: Of the 2080 patients who satisfied study eligibility criteria, 633 (30.4%) underwent neck dissection. Between 2018 and 2020, the rate of neck dissection was 39.0% (114/292). After multivariable adjustment, academic facility type, undergoing biopsy prior to surgery, and more radical surgery were significant predictors of receiving neck dissection. CONCLUSIONS: The results of this national analysis suggest that the utilization of guideline-concordant neck dissection for management of stage I-II supraglottic LSCC remains low and highlight the need to promote the practice of neck dissection for this patient population.

BACKGROUND: This systematic review aggregates the data of studies that include site-specific analyses of patients undergoing salvage surgery for residual or recurrent hypopharyngeal squamous cell carcinoma. METHODS: The primary outcomes are disease-free, disease-specific, and overall survival (DFS, DSS, and OS, respectively). Secondary outcomes include complications and postoperative feeding requirements. RESULTS: Fifteen studies met the inclusion criteria with a total of 442 patients. Two-year DFS is reported from 30.0 to 50.0% and 5-year DFS ranges from 15.0 to 57.1%. Five-year DSS ranges from 28.0 to 57.1%. Two-year OS ranges from 38.8 to 52.0% and 5-year OS ranges from 15.5 to 57.1%. Complications include pharyngocutaneous fistula (0.0-71.4%), carotid artery rupture (2.9-13.3%), and stomal stenosis (4.2-20.0%). Complete oral feeding achieved following surgery ranges from 61.9 to 100.0%, while complete gastrostomy tube dependence ranges from 0.0 to 28.6%. CONCLUSIONS: Salvage surgery for residual or recurrent hypopharyngeal squamous cell carcinoma has a relatively high complication rate and should be offered to patients with the understanding of a guarded prognosis.
RESUMO
BACKGROUND: Human papillomavirus (HPV) is causally linked to oropharyngeal squamous cell carcinoma (OPSCC). Testing for plasma tumor tissue modified viral (TTMV)-HPV DNA has emerged as a biomarker strategy for post-treatment surveillance to identify recurrent disease. We aimed to understand the prognostic and predictive potential of TTMV-HPV DNA when monitoring patients who had developed recurrent or metastatic (R/M) HPV+OPSCC. METHODS: This retrospective observational cohort study included 80 patients from 4 academic centers with R/M HPV+OPSCC if they had ≥ 1 plasma TTMV-HPV DNA test obtained at any point during their R/M disease course. Physician-reported clinical data and treatment history were captured in a centralized database, along with investigator-assessed response to therapy and survival. Descriptive statistics and non-parametric tests of association were employed along with survival analyses (Kaplan-Meier method). RESULTS: Sixteen (20 %) patients had ≥ 5 test results over time. Consecutive TTMV-HPV DNA tests were performed a median of 73 days apart. Median TTMV-HPV DNA scores were higher with an increasing per-patient number of metastatic sites (<2 vs. 2+; p < 0.01). Score changes over time were influenced by R/M treatment modality and became undetectable in 67 % (12/18) of patients who achieved a complete response to R/M therapy. Patients with detectable scores at last follow-up had significantly worse survival compared with those who were undetectable (log-rank test, p < 0.01). CONCLUSIONS: TTMV-HPV DNA appears useful as a prognostic tool for monitoring response to therapy in the R/M setting. In the future, TTMV-HPV DNA could be explored as an exploratory clinical trial endpoint in the metastatic setting.
RESUMO
BACKGROUND: Traditionally, patients undergoing free flap reconstruction for oral cavity defects have been given nothing by mouth for 6-14 days post-operatively due to concern for orocutaneous fistula development. METHODS: Multiple databases were screened for studies assessing the rate of orocutaneous fistula formation in early (≤5 days) versus late (>5 days) feeding groups following oral cavity free flap reconstruction. Fixed- and random-effects meta-analyses were used. RESULTS: One randomized controlled trial, one prospective cohort, and three retrospective cohort studies were included. The early feeding group displayed no significant increase in orocutaneous fistula formation (RD = -0.02, p = 0.06) or free flap failure (RD = -0.01, p = 0.39), with a significantly shorter hospital length of stay (mean difference [days] = -2.43, p < 0.01). CONCLUSIONS: While further prospective trials are necessary, initiation of oral intake before post-operative day 5 may be appropriate in properly selected patients following oral reconstruction.

OBJECTIVES: Clinical and imaging examinations frequently have indeterminate results during cancer surveillance, which can lead to overtreatment and cause psychological and financial harm to the patient. This study addresses the critical need to enhance diagnostic precision and decision-making in the management of HPV-associated oropharyngeal cancer. This study evaluated the utility of tumor tissue-modified viral (TTMV)-HPV DNA to resolve indeterminate disease status following definitive treatment for HPV-associated oropharyngeal cancer. MATERIALS AND METHODS: In this retrospective cohort, patients treated for HPV-associated oropharyngeal cancer at eight U.S. institutions and who received one or more TTMV-HPV DNA tests during post-treatment surveillance between February 2020 and January 2022 were included. RESULTS: Among 543 patients, 210 patients (38.7%; 210/543) experienced one or more clinically indeterminate findings (CIFs) during surveillance, with 503 CIFs recorded. Of those patients with an "indeterminate" disease status at a point during surveillance, 79 were associated with contemporaneous TTMV-HPV DNA testing. TTMV-HPV DNA testing demonstrated high accuracy (97.5%; 77/79) in correctly determining recurrence status. Patients whose disease status was "indeterminate" at the time of a positive TTMV-HPV DNA test were clinically confirmed to recur faster than those whose disease status was "no evidence of disease." Only 3% of patients (17/543) experienced indeterminate TTMV-HPV DNA tests during surveillance. Discordance between TTMV-HPV DNA tests and clinical results was minimal, with only 0.6% (3/543) of patients showing positive tests without recurrence. CONCLUSION: Our findings support the utility of circulating TTMV-HPV DNA in resolving indeterminate disease status and informing the subsequent clinical course.
