RESUMO

BACKGROUND: Patients with locally advanced head and neck squamous cell cancer (HNSCC) are treated with surgery followed by adjuvant (chemo) radiotherapy or definitive chemoradiation, but recurrence rates are high. Immune checkpoint blockade improves survival in patients with recurrent/metastatic HNSCC; however, the role of chemo-immunotherapy in the curative setting is not established. METHODS: This phase 2, single-arm, multicenter study evaluated neoadjuvant chemo-immunotherapy with carboplatin, nab-paclitaxel, and durvalumab in patients with resectable locally advanced HNSCC. The primary end point was a hypothesized pathologic complete response rate of 50%. After chemo-immunotherapy and surgical resection, patients received study-defined, pathologic risk adapted adjuvant therapy consisting of either durvalumab alone (low risk), involved field radiation plus weekly cisplatin and durvalumab (intermediate risk), or standard chemoradiation plus durvalumab (high risk). RESULTS: Between December 2017 and November 2021, 39 subjects were enrolled at three centers. Oral cavity was the most common primary site (69%). A total of 35 of 39 subjects underwent planned surgical resection; one subject had a delay in surgery due to treatment-related toxicity. The most common treatment-related adverse events were cytopenias, fatigue, and nausea. Post treatment imaging demonstrated an objective response rate of 57%. Pathologic complete response and major pathologic response were achieved in 29% and 49% of subjects who underwent planned surgery, respectively. The 1-year progression-free survival was 83.8% (95% confidence interval, 67.4%-92.4%). CONCLUSIONS: Neoadjuvant carboplatin, nab-paclitaxel, and durvalumab before surgical resection of HNSCC were safe and feasible. Although the primary end point was not met, encouraging rates of pathologic complete response and clinical to pathologic downstaging were observed.

RESUMO

OPINION STATEMENT: The role of induction chemotherapy in sinonasal cancers is promising; however, prospective studies with higher grades of evidence are needed. With the currently available literature, the authors would advocate for the use of induction chemotherapy (IC) in locally advanced sinonasal squamous cell carcinoma (T3-T4) for organ preservation and potentially for improved survival outcomes. In sinonasal undifferentiated carcinoma (SNUC), IC should be considered in all patients given its tendency for aggressive invasion and poor outcomes. In SNUC, response to IC may direct the modality of definitive treatment to follow. In responders (partial or complete), chemoradiation therapy should be strongly considered. In non-responders or in those with progression of disease, surgical therapy is favored. For esthesioneuroblastoma, surgical resection with negative margins and adjuvant radiation therapy remains the gold standard. However, IC may be considered for locally advanced disease especially with orbital invasion or in recurrent/distant disease. There is no definite indication for IC in sinonasal adenoid cystic carcinoma or sinonasal adenocarcinoma. Recommendations are summarized in Table 1.

RESUMO

BACKGROUND: Adavosertib (AZD1775) is an inhibitor of the Wee1 kinase. The authors conducted a phase 1b trial to evaluate the safety of adavosertib in combination with definitive chemoradiotherapy for patients with newly diagnosed, intermediate-risk/high-risk, locally advanced head and neck squamous cell carcinoma (HNSCC). METHODS: Twelve patients with intermediate-risk/high-risk HNSCC were enrolled, including those with p16-negative tumors of the oropharynx, p16-positive tumors of the oropharynx with ≥10 tobacco pack-years, and tumors of the larynx/hypopharynx regardless of p16 status. All patients were treated with an 8-week course of concurrent intensity-modulated radiotherapy at 70 grays (Gy) (2 Gy daily in weeks 1-7), cisplatin 30 mg/m2 weekly (in weeks 1-7), and adavosertib (twice daily on Monday, Tuesday, and Wednesday of weeks 1, 2, 4, 5, 7, and 8). The primary objective was to determine the maximum tolerated dose and the recommended phase 2 dose of adavosertib given concurrently with radiation and cisplatin. Secondary objectives were to determine the 12-week objective response rate and progression-free and overall survival. RESULTS: Three patients (25%) experienced a dose-limiting toxicity, including febrile neutropenia (n = 2) and grade 4 thromboembolism (n = 1). Two dose-limiting toxicities occurred with adavosertib at 150 mg. The median follow-up was 14.7 months. The 12-week posttreatment objective response rate determined by positron emission tomography/computed tomography was 100%. The 1-year progression-free and overall survival rates were both 90%. The maximum tolerated dose of adavosertib was 100 mg. CONCLUSIONS: Adavosertib 100 mg (twice daily on Monday, Tuesday, and Wednesday of weeks 1, 2, 4, 5, 7, and 8), in combination with 70 Gy of intensity-modulated radiotherapy and cisplatin 30 mg/m2 , is the recommended phase 2 dose for patients with HNSCC.

RESUMO

BACKGROUND: Human papillomavirus-positive (HPV+) squamous cell carcinoma of the oropharynx (OPSCC) is the most prevalent HPV-associated malignancy in the United States. Favorable treatment outcomes have led to increased interest in treatment de-escalation to reduce treatment morbidity as well as the development of prognostic markers to identify appropriately low-risk patients. Intratumoral genomic heterogeneity and copy number alteration burden have been demonstrated to be predictive of poor outcomes in many other cancers; therefore, we sought to determine whether intratumor heterogeneity and genomic instability are associated with poor outcomes in HPV+ OPSCC. METHODS: Tumor heterogeneity estimates were made based on targeted exome sequencing of 45 patients with HPV+ OPSCC tumors. Analysis of an additional cohort of HPV+ OPSCC tumors lacking matched normal sequencing allowed copy number analysis of 99 patient tumors. RESULTS: High intratumorally genomic heterogeneity and high numbers of copy number alterations were strongly associated with worse recurrence-free survival. Tumors with higher heterogeneity and frequent copy number alterations were associated with loss of distal 11q, which encodes key genes related to double-strand break repair, including ATM and MRE11A. CONCLUSIONS: Both intratumor genomic heterogeneity and high-burden copy number alterations are strongly associated with poor recurrence-free survival in patients with HPV+ OPSCC. The drivers of genomic instability and heterogeneity in these tumors remains to be elucidated. However, 11q loss and defective DNA double-strand break repair have been associated with genomic instability in other solid tumors. Copy number alteration burden and intratumoral heterogeneity represent promising avenues for risk stratification of patients with HPV+OPSCC.

RESUMO

PURPOSE: Racial disparities for overall survival (OS) in head and neck cancer have been well described. However, the extent to which these disparities exist for HPV-associated oropharyngeal squamous cell carcinoma (OPSCC), and the contribution of demographic, clinical, and socioeconomic status (SES) variables, is unknown. MATERIALS AND METHODS: Patients were identified from the Carolina Head and Neck Cancer Epidemiology Study (CHANCE), a population-based study in North Carolina. Cox proportional hazards regression models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for OS in black versus white patients with sequential adjustment sets. RESULTS: A total of 157 HPV-associated OPSCC patients were identified. Of these, 93% were white and 7% were black. Black patients with HPV-associated OPSCC were more likely to be younger, have an income <$20,000, live farther away from clinic where biopsy was performed, and have advanced T stage at diagnosis. Black patients had worse OS in the unadjusted analysis (HR 4.9, 95% CI 2.2-11.1, p < 0.0001). The racial disparity in OS slightly decreased when sequentially adjusting for demographic, clinical, and SES variables. However, HR for black race remained statistically elevated in the final adjustment set which controlled for age, sex, stage, smoking, alcohol use, and individual-level household income, insurance, and education level (HR 3.4, 95% CI 1.1-10.1, p = 0.028). CONCLUSION: This is the first population-based study that confirms persistence of racial disparities in HPV-associated OPSCC after controlling for demographic, clinical, and individual-level socioeconomic factors.

RESUMO

Until recently, palliative options for the treatment of platinum-refractory recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) have been cytotoxic chemotherapy and EGFR inhibitors. These agents offer limited efficacy with substantial toxicity. The development of novel immune checkpoint inhibitors has challenged the standard treatment. Pembrolizumab is a potent and highly selective humanized monoclonal antibody that blocks the interaction between PD-1, an immune checkpoint receptor and its ligands PD-L1 and -2. In August 2016, the US FDA approved the use of pembrolizumab in R/M HNSCC following disease progression on or after platinum-containing chemotherapy. This review highlights the pharmacology, therapeutic efficacy and tolerability data relevant to the use of pembrolizumab for the treatment of R/M HNSCC. Readers will gain greater insight into the HNSCC tumor microenvironment, available biomarkers, and learn about important clinical considerations associated with the use of pembrolizumab and similar immune checkpoint inhibitors.

RESUMO

Adenoid cystic carcinoma (AdCC) is a slow-growing salivary gland malignancy that relapses frequently. AdCCs of the submandibular gland exhibit unique differences in prognosis and treatment response to adjuvant radiotherapy compared to other sites, yet the role of tumor anatomic subsite on gene expression and tumor immune microenvironment (TIME) composition remains unclear. We used 87 samples, including 48 samples (27 AdCC and 21 normal salivary gland tissue samples) from 4 publicly available AdCC RNA sequencing datasets, a validation set of 33 minor gland AdCCs, and 39 samples from an in-house cohort (30 AdCC and 9 normal salivary gland samples). RNA sequencing data were used for single sample gene set enrichment analysis and TIME deconvolution. Quantitative PCR and multiplex immunofluorescence were performed on the in-house cohort. Wilcoxon rank-sum, nonparametric equality-of-medians tests and linear regression models were used to evaluate tumor subsite differences. AdCCs of different anatomic subsites including parotid, submandibular, sublingual, and minor salivary glands differed with respect to expression of several key tumorigenic pathways. Among the three major salivary glands, the reactive oxygen species (ROS)/nuclear factor erythroid 2-related factor 2 (NRF2) pathway signature was significantly underexpressed in AdCC of submandibular compared to parotid and sublingual glands while this association was not observed among normal glands. Additionally, the NRF2 pathway, whose expression was associated with favorable overall survival, was overexpressed in AdCCs of parotid gland compared to minor and submandibular glands. The TIME deconvolution identified differences in CD4+ T cell populations between AdCC of major and minor glands and natural killer (NK) cells among AdCC of minor, submandibular, and parotid glands while plasma cells were enriched in normal submandibular glands compared to other normal gland controls. Our data reveal key molecular differences in AdCC of different anatomic subsites. The ROS and NRF2 pathways are underexpressed in submandibular and minor AdCCs compared to parotid gland AdCCs, and NRF2 pathway expression is associated with favorable overall survival. The CD4+ T, NK, and plasma cell populations also vary by tumor subsites, suggesting that the observed submandibular AdCC tumor-intrinsic pathway differences may be responsible for influencing the TIME composition and survival differences.

RESUMO

BACKGROUND: Poor oral health has been identified as a prognostic factor potentially affecting the survival of patients with head and neck squamous cell carcinoma. However, evidence to date supporting this association has emanated from studies based on single cohorts with small-to-modest sample sizes. METHODS: Pooled analysis of 2449 head and neck squamous cell carcinoma participants from 4 studies of the International Head and Neck Cancer Epidemiology Consortium included data on periodontal disease, tooth brushing frequency, mouthwash use, numbers of natural teeth, and dental visits over the 10 years prior to diagnosis. Multivariable generalized linear regression models were used and adjusted for age, sex, race, geographic region, tumor site, tumor-node-metastasis stage, treatment modality, education, and smoking to estimate risk ratios (RR) of associations between measures of oral health and overall survival. RESULTS: Remaining natural teeth (10-19 teeth: RR = 0.81, 95% confidence interval [CI] = 0.69 to 0.95; ≥20 teeth: RR = 0.88, 95% CI = 0.78 to 0.99) and frequent dental visits (>5 visits: RR = 0.77, 95% CI = 0.66 to 0.91) were associated with better overall survival. The inverse association with natural teeth was most pronounced among patients with hypopharyngeal and/or laryngeal, and not otherwise specified head and neck squamous cell carcinoma. The association with dental visits was most pronounced among patients with oropharyngeal head and neck squamous cell carcinoma. Patient-reported gingival bleeding, tooth brushing, and report of ever use of mouthwash were not associated with overall survival. CONCLUSIONS: Good oral health as defined by maintenance of the natural dentition and frequent dental visits appears to be associated with improved overall survival among head and neck squamous cell carcinoma patients.

RESUMO

Human Papilloma Virus (HPV) testing is mandatory for all newly diagnosed oropharyngeal squamous cell carcinoma (OPSCC) due to its importance for prognostication and aiding in treatment decision making. Fine needle aspiration (FNA) is a widely used and accepted diagnostic tool for OPSCC. Although FNA can accurately determine histological diagnosis, results are often indeterminate or lack insufficient samples for HPV testing. For samples with an indeterminant FNA, we propose an alternate method for determining HPV status using circulating tumor tissue modified HPV DNA (ctHPVDNA). We report three cases that confirmed HPV status using ctHPVDNA following an indeterminate FNA. If validated, this non-invasive assay could prevent the need for repeat FNAs or operative biopsies for the sole purpose of determining HPV status.

RESUMO

OBJECTIVE: This article presents the dataset titled "Do you know how to Stop The Bleed®? [1]" The dataset contains the survey responses of 200 US persons aged 16 years and above regarding their knowledge of hemorrhage control, based on the American College of Surgeons Stop The Bleed® (STB) course [2]. RESULTS: Two hundred adults in the United States completed this web-based survey, which consisted of a quiz to assess STB knowledge. Factors that were not statistically correlated to STB knowledge retention included age, sex, race and education level up to college level. On the other hand, resuscitation coursework (p = 0.004) and income (p = 0.049) were important determinants of Stop the Bleed® knowledge. In particular, participants with CPR certification (p = 0.020) and/or a postgraduate degree (p = 0.015) scored higher than their counterparts in this sample cohort.

RESUMO

Background: Nucleus drop during cataract surgery is a dreaded complication and requires urgent vitreo-retinal intervention which is managed commonly using a fragmatome. However, a fragmatome is not readily available in routine ophthalmology set-ups because its use is very limited. On the other hand, a phaco-probe is commonly available with all surgeons and makes it cost-effective. Purpose: The purpose is to demonstrate the utility of a phaco-probe as an alternative to a fragmatome in managing nucleus drop during cataract surgery, making it cost-effective and less time-consuming and simple. Synopsis: The video shows two cases of complicated cataract surgery in which a nucleus is dropped in the vitreous cavity. The sleeve of the phaco-probe was removed, and infusion was disconnected to make it function as a fragmatome. We noted reduced lenticular repulsion from the phaco-handpiece tip as compared to the fragmatome, and no scleral burns were observed. The cases were completed by secondary placement of an intra-ocular lens in the sulcus in the same sitting. Thus, the phaco-probe can be considered to manage nucleus drop in the absence of a fragmatome. Highlights: A phaco-probe can be used as an alternative to a framgamtome, which is a cost-effective and simple technique. Video link: https://youtu.be/6c-40Bcijrc.

RESUMO

OBJECTIVES: Accurate monitoring of disease burden depends on accurate disease marker quantification. Although next-generation sequencing (NGS) is a promising technology for noninvasive monitoring, plasma cell-free DNA levels are often reported in misleading units that are confounded by non-disease-related factors. We proposed a novel strategy for calibrating NGS assays using spiked normalizers to improve precision and to promote standardization and harmonization of analyte concentrations. METHODS: In this study, we refined our NGS protocol to calculate absolute analyte concentrations to (1) adjust for assay efficiency, as judged by recovery of spiked synthetic normalizer DNAs, and (2) calibrate NGS values against droplet digital polymerase chain reaction (ddPCR). As a model target, we chose the Epstein-Barr virus (EBV) genome. In patient (n = 12) and mock (n = 12) plasmas, NGS and 2 EBV ddPCR assays were used to report EBV load in copies per mL of plasma. RESULTS: Next-generation sequencing was equally sensitive to ddPCR, with improved linearity when NGS values were normalized for spiked DNA read counts (R2 = 0.95 for normalized vs 0.91 for raw read concentrations). Linearity permitted NGS calibration to each ddPCR assay, achieving equivalent concentrations (copies/mL). CONCLUSIONS: Our novel strategy for calibrating NGS assays suggests potential for a universal reference material to overcome biological and preanalytical variables hindering traditional NGS strategies for quantifying disease burden.

RESUMO

Despite recent advancements in the field of neuro-ophthalmology, the rising rates of neurological and ophthalmological conditions, mismatches between supply and demand of clinicians, and an aging population underscore the urgent need to explore new therapeutic approaches within the field. Glucagon-like peptide 1 receptor agonists (GLP-1RAs), traditionally used in the treatment of type 2 diabetes, are becoming increasingly appreciated for their diverse applications. Recently, GLP-1RAs have been approved for the treatment of obesity and recognized for their cardioprotective effects. Emerging evidence indicates some GLP-1RAs can cross the blood-brain barrier and may have neuroprotective effects. Therefore, this article aims to review the literature on the neurologic and neuro-ophthalmic role of glucagon-like peptide 1 (GLP-1). This article describes GLP-1 peptide characteristics and the mechanisms mediating its known role in increasing insulin, decreasing glucagon, delaying gastric emptying, and promoting satiety. This article identifies the sources and targets of GLP-1 in the brain and review the mechanisms which mediate its neuroprotective effects, as well as implications for Alzheimer's disease (AD) and Parkinson's disease (PD). Furthermore, the preclinical works which unravel the effects of GLP-1 in ocular dynamics and the preclinical literature regarding GLP-1RA use in the management of several neuro-ophthalmic conditions, including diabetic retinopathy (DR), glaucoma, and idiopathic intracranial hypertension (IIH) are discussed.

RESUMO

OBJECTIVES: The delivery of healthcare has changed significantly over the past decades. This study analyzes the clinicodemographic factors and treatment patterns of head and neck squamous cell carcinoma (HNSCC) patients between 2004 and 2020. MATERIALS AND METHODS: Retrospective cohort analysis of HNSCC patients from the National Cancer Data Base from 2004 to 2020. RESULTS: A total of 164,290 patients were included. Increased times from diagnosis to definitive surgery (TTS) were seen across all facility types (academic centers, AC; non-academic centers, NAC) between 2004 and 2019, with NAC affected more. TTS < 15 days (RR = 1.05, 95%CI:1.05-1.09) and > 75 days (1.07, 95%CI:1.05-1.09) were associated with increased mortality risk. This association was more prominent among HPV + HNSCC (RR = 1.45; 95%CI:1.18-1.78). Treatment in AC was associated with a decreased mortality risk (RR = 0.94, 95%CI:0.93-0.95). Despite the universal increase in wait times from 2004 to 2019, short-term mortality was significantly decreased from 2016 to 2019, relative to 2004-2007 (3-month mortality: RR = 0.77, 95%CI:0.70-0.85; 12-month mortality: RR = 0.80, 95%CI:0.77-0.84). Wait times decreased in 2020. CONCLUSIONS: TTS increased between 2004 and 2019, with NAC affected more. However, despite longer wait times, short-term survival increased significantly. Very short (<15 days) and very long (>75 days) TTS were associated with increased mortality risk. Patients with HPV + HNSCC have the highest increase among those treated > 75 days from diagnosis. Treatment at AC was associated with improved survival, which could be explained by the presence of multidisciplinary teams and subspecialists that may be less available at NAC. The 2021 NCDB data are required for a comprehensive analysis of wait times in 2020.

RESUMO

BACKGROUND: In rural states, travel burden for complex cancer care required for head and neck squamous cell carcinoma (HNSCC) may affect patient survival, but its impact is unknown. METHODS: Patients with HPV-negative HNSCC were retrospectively identified from a statewide, population-based study. Euclidian distance from the home address to the treatment center was calculated for radiation therapy, surgery, and chemotherapy. Multivariable Cox proportional hazards models were used to examine the risk of 5-year mortality with increasing travel quartiles. RESULTS: There were 936 patients with HPV-negative HNSCC with a mean age of 60. Patients traveled a median distance of 10.2, 11.1, and 10.9 miles to receive radiation therapy, surgery, and chemotherapy, respectively. Patients in the fourth distance quartile were more likely to live in a rural location (p < 0.001) and receive treatment at an academic hospital (p < 0.001). Adjusted overall survival (OS) improved proportionally to distance traveled, with improved OS remaining significant for patients who traveled the furthest for care (third and fourth quartile by distance). Relative to patients in the first quartile, patients in the fourth had a reduced risk of mortality with radiation (HR 0.59, 95% CI 0.42-0.83; p = 0.002), surgery (HR 0.47, 95% CI 0.30-0.75; p = 0.001), and chemotherapy (HR 0.56, 95% CI 0.35-0.91; p = 0.020). CONCLUSION: For patients in this population-based cohort, those traveling greater distances for treatment of HPV-negative HNSCC had improved OS. This analysis suggests that the benefits of coordinated, multidisciplinary care may outweigh the barriers of travel burden for these patients.

RESUMO

PURPOSE: To provide evidence-based recommendations for practicing physicians and other health care providers on immunotherapy and biomarker testing for head and neck cancers. METHODS: ASCO convened an Expert Panel of medical oncology, surgical oncology, radiation oncology, radiology, pathology, and patient advocacy experts to conduct a literature search, including systematic reviews, meta-analyses, randomized controlled trials, and prospective and retrospective comparative observational studies published from 2000 through 2022. Outcomes of interest included survival, overall response, and locoregional control. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations. RESULTS: The literature search identified 28 relevant studies to inform the evidence base for this guideline. RECOMMENDATIONS: When possible, evidence-based recommendations were developed to address biomarker testing, first-line treatment regimens based on programmed death ligand-1 scores, immunotherapy in platinum-refractory recurrent or metastatic head and neck squamous cell carcinoma, immunotherapy in nasopharyngeal carcinoma, and radiation therapy in combination with immunotherapy for treatment of local recurrence.Additional information is available at www.asco.org/head-neck-cancer-guidelines.

RESUMO

Sexual intercourse is the major means of HIV transmission, yet the impact of semen on HIV infection of CD4(+) T cells remains unclear. To resolve this conundrum, we measured CD4(+) target cell infection with X4 tropic HIV IIIB and HC4 and R5 tropic HIV BaL and SF162 after incubation with centrifuged seminal plasma (SP) from HIV-negative donors and assessed the impact of SP on critical determinants of target cell susceptibility to HIV infection. We found that SP potently protects CD4(+) T cells from infection with X4 and R5 tropic HIV in a dose- and time-dependent manner. SP caused a diminution in CD4(+) T cell surface expression of the HIVR CD4 and enhanced surface expression of the HIV coreceptor CCR5. Consequently, SP protected CD4(+) T cells from infection with R5 tropic HIV less potently than it protected CD4(+) T cells from infection with X4 tropic HIV. SP also reduced CD4(+) T cell activation and proliferation, and the magnitude of SP-mediated suppression of target cell CD4 expression, activation, and proliferation correlated closely with the magnitude of the protection of CD4(+) T cells from infection with HIV. Taken together, these data show that semen protects CD4(+) T cells from HIV infection by restricting critical determinants of CD4(+) target cell susceptibility to HIV infection. Further, semen contributes to the selective transmission of R5 tropic HIV to CD4(+) target cells.

RESUMO

Venous thromboembolism (VTE) is a significant cardiovascular disease with a relatively high incidence rate, presenting a significant clinical burden. Its effective diagnosis and treatment are critical to the proper management of patients with the condition. Though there are several risk factors associated with VTE, advanced age itself presents as particularly significant, with age-related risk alone leading to high incidences of VTE in elderly patients even in the absence of other risk factors or relevant medical history. We present such a case of an elderly male patient with limited risk factors beyond advanced age who nonetheless presented with symptoms of deep-vein thrombosis (DVT) following a mild traumatic injury, and upon further inspection, was found to have a pulmonary embolism (PE). Proper precautions taken in assessing potential PE upon initial discovery of DVT and post-diagnostic management were critical in this patient's outcome.

RESUMO

BACKGROUND: There is a paucity of data on financial toxicity among patients with head and neck squamous cell carcinoma (HNSCC). MATERIALS: This was a retrospective, cross-sectional study of patients with HNSCC surveyed at an outpatient oncology clinic. RESULTS: The sample included 202 patients with HNSCC with a mean age of 59.6 years (SD 10.0). There were 53 patients (26%) with self-reported financial burden. Education of high school or less was a significant predictor of self-reported financial burden (OR 2.52, 95% CI 1.03-6.14, p = 0.042). Patients reporting financial burden had significantly worse physical (p = 0.003), mental (p = 0.003), and functional (p = 0.036) health-related quality of life (HRQOL). Patients reporting financial burden appeared to have lower 5-year overall survival (74.3% vs. 83.9%, p = 0.165), but this association did not reach statistical significance. CONCLUSION: Financial burden or toxicity may affect approximately a quarter of patients with HNSCC and appears to be associated with worse HRQOL outcomes.

RESUMO

Human papillomavirus-positive (HPV+) squamous cell carcinoma of the oropharynx (OPSCC) is the most prevalent HPV-associated malignancy in the United States and is primarily caused by HPV subtype 16 (HPV16). Favorable treatment outcomes have led to increasing interest in treatment deescalation to reduce treatment-related morbidity. Prognostic biomarkers are needed to identify appropriately low-risk patients for reduced treatment intensity. Targeted DNA sequencing including all HPV16 open reading frames was performed on tumors from 104 patients with HPV16+ OPSCC treated at a single center. Genotypes closely related to the HPV16-A1 reference were associated with increased numbers of somatic copy-number variants in the human genome and poor recurrence-free survival (RFS). Genotypes divergent from HPV16-A1 were associated with favorable RFS. These findings were independent of tobacco smoke exposure. Total RNA sequencing was performed on a second independent cohort of 89 HPV16+ OPSCC cases. HPV16 genotypes divergent from HPV16-A1 were again validated in this independent cohort, to be prognostic of improved RFS in patients with moderate (less than 30 pack-years) or low (no more than 10 pack-years) of tobacco smoke exposure. In summary, we show in two independent cohorts that viral sequence divergence from the HPV16-A1 reference is correlated with improved RFS in patients with moderate or low tobacco smoke exposure. IMPLICATIONS: HPV16 genotype is a potential biomarker that could be easily adopted to guide therapeutic decision-making related to deescalation therapy.
