RESUMO

BACKGROUNDTransrenal cell-free tumor DNA (TR-ctDNA), which transits from the bloodstream into urine, has the potential to enable noninvasive cancer detection for a wide variety of nonurologic cancer types.MethodsUsing whole-genome sequencing, we discovered that urine TR-ctDNA fragments across multiple cancer types are predominantly ultrashort (<50 bp) and, therefore, likely to be missed by conventional ctDNA assays. We developed an ultrashort droplet digital PCR assay to detect TR-ctDNA originating from HPV-associated oropharyngeal squamous cell carcinoma (HPV+ OPSCC) and confirmed that assaying ultrashort DNA is critical for sensitive cancer detection from urine samples.ResultsTR-ctDNA was concordant with plasma ctDNA for cancer detection in patients with HPV+ OPSCC. As proof of concept for using urine TR-ctDNA for posttreatment surveillance, in a small longitudinal case series, TR-ctDNA showed promise for noninvasive detection of recurrence of HPV+ OPSCC.ConclusionOur data indicate that focusing on ultrashort fragments of TR-ctDNA will be important for realizing the full potential of urine-based cancer diagnostics. This has implications for urine-based detection of a wide variety of cancer types and for facilitating access to care through at-home specimen collections.FundingNIH grants R33 CA229023, R21 CA225493; NIH/National Cancer Institute grants U01 CA183848, R01 CA184153, and P30CA046592; American Cancer Society RSG-18-062-01-TBG; American Cancer Society Mission Boost grant MBGI-22-056-01-MBG; and the A.

RESUMO

OBJECTIVE: To evaluate whether nodal yields and ratios based on level serves as prognostic indicators in patients with oral cavity squamous cell carcinoma undergoing neck dissection. MATERIALS AND METHODS: A retrospective analysis of 342 patients with oral cavity squamous cell carcinoma treated surgically between 1998 and 2017 were included.Demographics and clinicopathologic data were collated. Disease specific survival and overall survival were analyzed via Kaplan-Meier method and log-rank test as well as univariable and multivariable Cox models. RESULTS: Total nodal yield is associated with improved overall and disease specific survival (p < 0.01). Total positive nodal yield (p < 0.01), positive nodal ratio per level (p < 0.001), and identification of <4 lymph nodes/level (p < 0.001) are associated with worse disease specific survival and overall survival. A ratio of at least 4 lymph nodes/level dissected yields the maximal hazard ratio on for both disease specific and overall survival optimizes the Kaplan-Meier split between survival groups. After controlling for sex, age, margin status, disease stage, extranodal extension, perineural invasion, and lymphovascular invasion as fixed covariates in the Cox models, a nodal level ratio of 4 lymph nodes/level provides hazard ratio (95% CI) of 3.59 (1.69, 7.60); p < 0.0006) for disease free survival and 2.90 (1.54, 5.46; p < 0.001) for overall survival. CONCLUSION: Nodal level ratio of < 4 lymph nodes/level is associated with worse disease specific and overall survival in oral cavity squamous cell carcinoma. This level-specific metric may prove useful qualitatively and in predicting survival in oral cavity cancer with broader utility to address variations in levels of neck dissection performed.

RESUMO

BACKGROUND: Many options for free tissue transfer have been described for head and neck reconstruction. While functional outcomes remain paramount, aesthetic considerations like color match can be equally consequential for patient quality of life. It is important to understand differences in color match based on flap donor site for head and neck reconstruction. METHODS: A retrospective review was performed of patients who underwent head and neck reconstruction with free tissue transfer at a tertiary care academic medical center between November 2012 and November 2020. Patients with documented pictures of their reconstruction and external skin paddles were considered. Patient demographics and surgery specific factors were recorded. Objective differences in color match were obtained by calculating the International Commission on Illumination Delta E 2000 (dE2000) score. Standard univariate descriptive statistics and multivariable statistical analyses were performed. RESULTS: Lateral arm, parascapular, and medial sural artery perforator (MSAP) free tissue transfer performed favorably compared to other donor sites, whereas anterolateral thigh flaps had the highest average dE2000 scores. Differences in dE2000 scores were mitigated by post-operative radiation to the flap site and with increasing time beyond 6 months post-operatively. CONCLUSIONS: We provide an objective assessment of external skin color match in patients undergoing free tissue transfer for head and neck cancer by donor site. MSAP, lateral arm, and parascapular free flaps performed well compared to traditional donor sites. These differences are more significant at the face and mandible when compared to the neck, but diminish 6 months after surgery and with post-operative radiation to the free flap skin paddle.

RESUMO

OBJECTIVES: To develop a high-performance droplet digital PCR (ddPCR) assay capable of enhancing the detection of human papillomavirus (HPV) circulating tumor DNA (ctDNA) in plasma from patients with HPV-associated oropharyngeal squamous cell carcinoma (HPV+ OPSCC). MATERIALS AND METHODS: Plasma samples from subjects with HPV+ OPSCC were collected. We developed a high-performance ddPCR assay designed to simultaneously target nine regions of the HPV16 genome. RESULTS: The new assay termed 'ctDNA HPV16 Assessment using Multiple Probes' (CHAMP- 16) yielded significantly higher HPV16 counts compared to our previously validated 'Single-Probe' (SP) assay and a commercially available NavDx® assay. Analytical validation demonstrated that the CHAMP-16 assay had a limit of detection (LoD) of 4.1 copies per reaction, corresponding to < 1 genome equivalent (GE) of HPV16. When tested on plasma ctDNA from 21 patients with early-stage HPV+ OPSCC and known HPV16 ctDNA using the SP assay, all patients were positive for HPV16 ctDNA in both assays and the CHAMP-16 assay displayed 6.6-fold higher HPV16 signal on average. Finally, in a longitudinal analysis of samples from a patient with recurrent disease, the CHAMP-16 assay detected HPV16 ctDNA signal âˆ¼ 20 months prior to the conventional SP assay. CONCLUSION: Increased HPV16 signal detection using the CHAMP-16 assay suggests the potential for detection of recurrences significantly earlier than with conventional ddPCR assays in patients with HPV16+ OPSCC. Critically, this multi-probe approach maintains the cost-benefit advantage of ddPCR over next generation sequencing (NGS) approaches, supporting the cost-effectiveness of this assay for both large population screening and routine post-treatment surveillance.

RESUMO

A wide variety of grafting materials and techniques can be used to create functional and aesthetic changes in rhinoplasty. Choosing the optimal grafting approach is critical to achieving an optimal patient outcome. We present a review of autografts, allografts, and alloplasts used in primary and revision rhinoplasty and discuss factors that impact graft choice. Autologous grafts serve as the pillar for grafting material in rhinoplasty given their reliable long-term outcomes, low rates of infection, resorption, and extrusion, and ability to provide structural scaffolding as well as contour. Cadaveric allografts can be utilized as a source of grafting material in certain clinical scenarios including revision rhinoplasty and have been shown to be equally safe and effective as autologous grafts while avoiding donor-site morbidity. Alloplasts can prove useful in rhinoplasty in cases of iatrogenic nasal deformities or revision cases. Careful consideration of clinical scenario, patient factors, and outcome goals is necessary to choose the appropriate grafting approach to address functional and cosmetic outcomes.

RESUMO

BACKGROUND: Development of evidence-based post-treatment surveillance guidelines in recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC) is limited by comprehensive documentation of patterns of recurrence and metastatic spread. METHODS: A retrospective analysis of patients diagnosed with R/M HNSCC at a National Cancer Institute-designated cancer center between 1998- 2019 was performed (n = 447). Univariate and multivariate analysis identified patterns of recurrence and predictors of survival. RESULTS: Median overall survival (mOS) improved over time (6.7 months in 1998-2007 to 11.8 months in 2008-2019, p = .006). Predictors of worse mOS included human papillomavirus (HPV) negativity (hazard ratio [HR], 1.8; 95% confidence interval [CI], 1.2-2.6), high neutrophil/lymphocyte ratio (HR, 2.1 [1.4-3.0], disease-free interval (DFI) ≤6 months (HR, 1.4 [1.02-2.0]), and poor performance status (Eastern Cooperative Oncology Group, ≥2; HR, 1.91.1-3.4). In this cohort, 50.6% of recurrences occurred within 6 months of treatment completion, 72.5% occurred within 1 year, and 88.6% occurred within 2 years. Metachronous distant metastases were more likely to occur in patients with HPV-positive disease (odds ratio [OR], 2.3 [1.4-4.0]), DFI >6 months (OR, 2.4 [1.5-4.0]), and body mass index ≥30 (OR, 2.3 [1.1-4.8]). Oligometastatic disease treated with local ablative therapy was associated with improved survival over polymetastatic disease (HR, 0.36; 95% CI, 0.24-0.55). CONCLUSION: These data regarding patterns of distant metastasis in HNSCC support the clinical utility of early detection of recurrence. Patterns of recurrence in this population can be used to inform individualized surveillance programs as well as to risk-stratify eligible patients for clinical trials. PLAIN LANGUAGE SUMMARY: After treatment for head and neck cancer (HNC), patients are at risk of recurrence at prior sites of disease or at distant sites in the body. This study includes a large group of patients with recurrent or metastatic HNC and examines factors associated with survival outcomes and recurrence patterns. Patients with human papillomavirus (HPV)-positive HNC have good survival outcomes, but if they recur, this may be in distant regions of the body and may occur later than HPV-negative patients. These data argue for personalized follow-up schedules for patients with HNC, perhaps incorporating imaging studies or novel blood tests.

RESUMO

Facial skin defects pose unique challenges for the reconstructive surgeon. Aesthetically complex areas involving a free margin-such as the ear, eyelid, columella, columella-lobule interface, soft tissue triangle, alar rim, and internal nasal lining-are particularly demanding, as secondary soft tissue contracture in these locations can lead to a very poor cosmetic outcome. In these cases, composite grafts offer an ideal combination of soft tissue coverage and structural rigidity, all accomplished in a single-stage surgery. Composite grafts are often underused in facial reconstructive surgery due to the tenuous blood supply and high reported rates of graft failure.

RESUMO

OBJECTIVE: To explore challenges and opportunities for supporting midcareer women otolaryngologists in the areas of negotiation and sponsorship. STUDY DESIGN: Qualitative approach using semistructured interviews. SETTING: Online multi-institutional interviews. METHODS: This study was performed from June to August 2021. Women otolaryngologists representing diverse subspecialties, training, and practice environments were recruited via a purposive criterion-based sampling approach. Semistructured interviews were transcribed, coded, and analyzed via an inductive-deductive approach to produce a thematic content analysis. RESULTS: Among the 12 women interviewees, who represented 7 subspecialties, the majority were Caucasian (58%) and in academic practice (50%). The median residency graduation year was 2002 (range, 1982-2013). Participants expressed several challenges that women otolaryngologists face with respect to negotiation, including the absence of systematic formal negotiation training, gendered expectations that women experience during negotiations, and a perceived lack of power in negotiations. Obstacles to effective sponsorship included difficulty in the identification of sponsors and the influence of gender and related systemic biases that hindered sponsorship opportunities. CONCLUSION: Notable gender disparities exist for negotiation and sponsorship in the midcareer stage for women otolaryngologists. Women start at a disadvantage due to a lack of negotiation training and access to sponsors, which is exacerbated by systemic gender bias and power differentials as women advance in their careers. This study highlights opportunities to improve negotiation and sponsorship for women, with the goal of promoting a more diverse workforce.

RESUMO

Cancer biomarkers are a promising tool for cancer detection, personalization of therapy, and monitoring of treatment response or recurrence. "Liquid biopsy" commonly refers to minimally invasive or non-invasive sampling of a bodily fluid (i.e., blood, urine, saliva) for detection of cancer biomarkers such as circulating tumor cells or cell-free tumor DNA (ctDNA). These methods offer a means to collect frequent tumor assessments without needing surgical biopsies. Despite much progress with blood-based liquid biopsy approaches, there are limitations-including the limited amount of blood that can be drawn from a person and challenges with collecting blood samples at frequent intervals to capture ctDNA biomarker kinetics. These limitations are important because ctDNA is present at extremely low levels in plasma and there is evidence that measuring ctDNA biomarker kinetics over time can be useful for clinical prediction. Additionally, blood-based assays require access to trained phlebotomists and often a trip to a healthcare facility. In contrast, urine is a body fluid that can be self-collected from a patient's home, at frequent intervals, and mailed to a laboratory for analysis. Multiple reports indicate that fragments of ctDNA pass from the bloodstream through the kidney's glomerular filtration system into the urine, where they are known as trans-renal ctDNA (TR-ctDNA). Accumulating studies indicate that the limitations of blood based ctDNA approaches for cancer can be overcome by measuring TR-ctDNA. Here, we review current knowledge about TR-ctDNA in urine as a cancer biomarker approach, and discuss its clinical potential and open questions in this research field.

RESUMO

The COVID-19 pandemic has fundamentally changed healthcare access, delivery, and treatment paradigms throughout oncology. Patients with head and neck cancer comprise an especially vulnerable population due to the nature of their disease and the transmission mechanism of the SARS-CoV-2 virus. The consequences of triage decisions and delays in care have serious psychosocial implications for patients. The development of structured psychosocial support programs, coupled with clear and consistent communication from treating physicians, can help mitigate perceptions of abandonment and distress that may accompany delays in care. As the unpredictability of the pandemic's course continues to burden both providers and patients, we must be proactive in addressing the psychosocial implications of these delays in care.

RESUMO

Human papillomavirus (HPV) related oropharyngeal squamous cell carcinoma (OPSCC) is associated with improved outcomes compared to non-virally mediated disease. Clinical trials are actively investigating de-escalation strategies to maintain excellent survival outcomes while minimizing toxicity. Delivery of effective precision medicine-based therapeutic approaches are strengthened by the identification of biomarkers to predict treatment response. Plasma circulating tumor (ct) DNA is the most studied liquid biomarker in head and neck cancer and has shown great promise in the ability to determine treatment response and monitor for disease recurrence. In this review, we examine the emerging evidence for ctDNA as a biomarker in HPV related OPSCC and discuss opportunities for future investigation and integration into clinical practice.

RESUMO

INTRODUCTION/OBJECTIVE: Historically, myringotomy, and the insertion of tympanostomy tubes has served as one of the initial surgical training experiences for residents. Resident experience with this procedure since the introduction of pneumococcal conjugate vaccines has not been well described in the literature. The objective of this study was to identify trends in resident training experience with chronic otitis media-related surgeries, such as myringotomy and tympanostomy tube placement. While multiple factors influence resident experience, we hypothesize that resident experience has decreased since the introduction of the pneumococcal 13-valent conjugate vaccine (PCV13). METHODS AND MATERIALS: In a retrospective review of Accreditation Council for Graduate Medical Education (ACGME) National Data Reports, mean number of myringotomy and tympanostomy tube cases logged in the Resident Case Log System from 2006 to 2019 were collated and plotted against years to identify monotonic trends. Mann-Whitney U test was used to compare pre-PCV13 era and post-PCV13 era data. RESULTS: Since the introduction of PCV13, there is a national decreasing trend in the myringotomy and tympanostomy tube placement by otolaryngology residents (P = .001). CONCLUSIONS: Otologic surgeries are an important part of resident education and historically have served as one of the initial surgical training experiences for residents. There has been a significant reduction in the number of myringotomy and tympanostomy procedures performed by otolaryngology residents in the past decade. While multiple factors influence resident experience, it is possible that introduction of PCV13 has impacted resident exposure to myringotomy and tympanostomy tube placement. Resident proficiency with this procedure has likely not been affected by introduction of PCV13. Data should be reassessed in 5 years to determine if an impact of the PCV13 vaccine on resident training is evident.

RESUMO

OBJECTIVE: To evaluate the pattern of presentation and management of laryngotracheobronchial amyloidosis at a tertiary care academic center over a 27 year period. METHODS: In a retrospective review, the electronic medical record at a tertiary care academic center was queried for encounters with 3 laryngologists between 1996 and 2019 which included the ICD-9 or ICD-10 diagnosis of amyloidosis. Demographics, clinical presentation, referral diagnoses, medical history, family history, laboratory values, radiology studies, and treatment modalities of subjects were collated. Results were analyzed using standard univariate descriptive statistics. RESULTS: Seventeen subjects were identified with an average age at diagnosis of 58 years (range 26-76 years). The most common amyloid type on biopsy was immunoglobulin light chain (AL) subtype. The most common location of laryngeal amyloid at diagnosis was the glottis and disease was more likely to be bilateral at the time of diagnosis in this location. Supraglottic disease more often had a unilateral presentation and had a tendency to spread to additional laryngeal subsites. Nearly 25% of subjects had associated systemic disease, including multiple myeloma, auto-immune disease, and familial ATTR mutation. CONCLUSIONS: The overall rate of associated systemic disease was low in our study cohort; however, it is higher than typically referenced in extant literature. Our cohort demonstrates that while laryngeal amyloidosis is a chronic condition, the behavior is generally indolent with a low treatment burden.

RESUMO

Importance: Recent insights into the biologic characteristics and treatment of oropharyngeal cancer may help inform improvements in prognostic modeling. A bayesian multistate model incorporates sophisticated statistical techniques to provide individualized predictions of survival and recurrence outcomes for patients with newly diagnosed oropharyngeal cancer. Objective: To develop a model for individualized survival, locoregional recurrence, and distant metastasis prognostication for patients with newly diagnosed oropharyngeal cancer, incorporating clinical, oncologic, and imaging data. Design, Setting, and Participants: In this prognostic study, a data set was used comprising 840 patients with newly diagnosed oropharyngeal cancer treated at a National Cancer Institute-designated center between January 2003 and August 2016; analysis was performed between January 2019 and June 2020. Using these data, a bayesian multistate model was developed that can be used to obtain individualized predictions. The prognostic performance of the model was validated using data from 447 patients treated for oropharyngeal cancer at Erasmus Medical Center in the Netherlands. Exposures: Clinical/oncologic factors and imaging biomarkers collected at or before initiation of first-line therapy. Main Outcomes and Measures: Overall survival, locoregional recurrence, and distant metastasis after first-line cancer treatment. Results: Of the 840 patients included in the National Cancer Institute-designated center, 715 (85.1%) were men and 268 (31.9%) were current smokers. The Erasmus Medical Center cohort comprised 300 (67.1%) men, with 350 (78.3%) current smokers. Model predictions for 5-year overall survival demonstrated good discrimination, with area under the curve values of 0.81 for the model with and 0.78 for the model without imaging variables. Application of the model without imaging data in the independent Dutch validation cohort resulted in an area under the curve of 0.75. This model possesses good calibration and stratifies patients well in terms of likely outcomes among many competing events. Conclusions and Relevance: In this prognostic study, a multistate model of oropharyngeal cancer incorporating imaging biomarkers appeared to estimate and discriminate locoregional recurrence from distant metastases. Providing personalized predictions of multiple outcomes increases the information available for patients and clinicians. The web-based application designed in this study may serve as a useful tool for generating predictions and visualizing likely outcomes for a specific patient.

RESUMO

OPINION STATEMENT: Human papilloma virus (HPV) related head and neck cancer is rising in prevalence, preferentially affecting young patients and imparting long term toxicities. Despite this, there are no screening tests or clinical biomarkers for treatment monitoring. HPV circulating tumor DNA (HPV ctDNA) represents a novel circulating biomarker which may provide real-time assessment of tumor response to therapy and recurrence. Early work suggests the promise of this assay as a predictive biomarker in numerous clinical settings, namely risk of recurrence after chemoradiation in locally advanced disease. Advancement of these findings to the clinic will require a collaborative effort in the field, including technical harmonization of assay testing characteristics, understanding of the normal kinetics in patients being treated with standard of care therapies, and appropriately designed phase III trials prior to implementation in the clinic. If successful, HPV ctDNA has the potential to revolutionize clinical trial treatment paradigms and transform patient care.

RESUMO

OBJECTIVES: To develop a novel multispecialty simulation-based course that teaches both technical and nontechnical skills in the management of adult and pediatric critical airways to graduating medical students and 2) to encourage a collaborative, multispecialty approach to the management of a difficult airway amongst fourth-year medical students who have enrolled in otolaryngology, anesthesia, and emergency medicine residency programs. METHODS: Fourth-year medical student who had matched into otolaryngology, anesthesia, and emergency medicine participated in an intensive half-day course consisting of a series of hands-on skills stations with increasing complexity, followed by simulated complex patient scenarios designed for shared management of airway emergencies. Participants completed questionnaires prior to and immediately after the course. Fischer's exact test was utilized to compare data between the precourse and postcourse surveys. Free-text responses were qualitatively assessed to inform course development. RESULTS: Thirty-four medical students were enrolled (6 otolaryngology, 15 anesthesia, 13 emergency medicine), and 30 students completed both surveys. Fisher's exact test demonstrated improved confidence (P < .05) for every skill. More than 85% of participants strongly agreed or agreed that the intervention was useful in developing their knowledge, technical skills, and self-confidence and in improving clinical performance prior to residency. CONCLUSIONS: This critical airway course introduces a multispecialty simulation-based course designed to impart graduating medical students with the necessary knowledge, skills, and behaviors for critical airway management while fostering interprofessional collaboration. Our course was successful in improving confidence and was perceived as useful in developing knowledge, technical skills, self-confidence, and clinical performance prior to residency.

RESUMO

BACKGROUND: A gender pay gap has been reported across many professions, including medicine. METHODS: Surgeons employed at complex Veterans Affairs Medical Centers (VAMC) nationwide in 2016 were identified. Data on salary, gender, years since medical school graduation, professorship status, h-index, and geographic location were collected. RESULTS: Of 1993 surgeons nationwide, 23% were female. On average, female surgeons had significantly lower salaries compared to male surgeons ($268,429 ± 41,339 versus $287,717 ± 45,379, respectively; p < 0.001). Among each surgical specialty, there were no significant differences in salary on univariate analysis. Women were underrepresented in higher paying specialties and more heavily represented in lower paying specialties. On multivariate analysis, gender (p < 0.001), time since medical school graduation (p < 0.001), surgical specialty (p = 0.031), h-index (p < 0.001), and geographic location (p < 0.001) were significant predictors of salary. CONCLUSION: Female gender significantly predicted lower salary among VAMC surgeons, however within each surgical specialty, there was no significant gender pay gap. SENTENCE SUMMARY: Independent predictors of salary included gender, surgical specialty, experience, h-index, and geographic location. Although female surgeons had lower overall salaries compared to male surgeons in the Veterans Health Administration (VHA), there were no significant gender differences in salary among each surgical specialty. Pay transparency, unique to the VHA, along with the use of rational and objective criteria to establish and adjust salaries, may play a role in reducing the gender pay gap among VHA surgeons.

RESUMO

OBJECTIVES/HYPOTHESIS: To determine if gender pay disparity exists amongst otolaryngologists employed by the Veterans Health Administration (VHA). STUDY DESIGN: cross-sectional analysis. METHODS: Board-certified otolaryngologists employed at all complex Veterans Affairs Medical Centers (VAMCs) in 2016 were identified. Salaries were collated using the Enterprise Human Resources Integration-Statistical Data Mart dataset. Additional variables, including gender, years since medical school graduation, professorship status, h-index, and geographic location were collected. A multivariate linear regression analysis was performed where salary was the primary outcome of interest and gender was accounted for as an independent predictor while controlling for professional characteristics, geographic location, and seniority. RESULTS: Sixty-nine VHA surgical programs with an operative designation of "complex" were identified. Two hundred sixty board-certified otolaryngologists, including 197 (75.8%) men and 63 (24.2%) women, were identified. Salary data were available on 210 of these otolaryngologists. In 2016, the mean salary for male and female otolaryngologists was not significantly different ($266,707 ± $31,624 vs. $264,674 ± $27,027, P = .918) nor were salaries in early career ($243,979 ± $31,749 vs. $254,625 ± $24,558, respectively; P = .416). On multivariate linear regression analysis, number of years since graduation (P = .009) and h-index (P = .049) were independent predictors of salary, but gender, geographic location, and faculty rank were not. CONCLUSIONS: Although the gender pay gap persists in many areas of medicine and surgery, otolaryngologists employed at complex VAMCs do not experience gender pay disparity. The use of specific and objective criteria to establish and adjust salaries can reduce and potentially eliminate gender pay disparity. These findings may help to guide institutional policies in other practice environments. LEVEL OF EVIDENCE: 2b. Laryngoscope, 129:113-118, 2019.
