RESUMO

Head and neck cancer is a potentially traumatizing disease with the potential to impact many of the functions which are core to human life: eating, drinking, breathing, and speaking. Patients with head and neck cancer are disproportionately impacted by socioeconomic challenges, social stigma, and difficult decisions about treatment approaches. Herein, the authors review foundational ethical principles and frameworks to guide care of these patients. The authors discuss specific challenges including shared decision-making and advance care planning. The authors further discuss palliative care with a discussion of the role of surgery as a component of palliation.

RESUMO

PURPOSE: Patients undergoing head and neck cancer surgery after prior radiation or chemoradiation are at high risk for wound complications. Hypothyroidism is a known risk factor for wound complications, especially fistulae after salvage total laryngectomy. The purpose of this phase II clinical trial is to investigate the effect of perioperative intravenous levothyroxine supplementation on wound complications in patients undergoing salvage total laryngectomy. PATIENTS AND METHODS: Euthyroid patients previously treated with radiation/chemoradiation undergoing total laryngectomy were prospectively recruited (n = 72). Postoperatively, intravenous levothyroxine was administered at a weight-based dose (1.3 mcg/kg/d) and transitioned to enteral dosing on day 7. Free T3, T4, and thyroid-stimulating hormones were collected, and dosing was adjusted accordingly. The primary endpoints were rates of fistula formation and fistula requiring reoperation, compared with matched historic controls. All patients were monitored for adverse effects. RESULTS: The rate of postoperative hypothyroidism was 21% compared with 49% in a matched historic cohort. The rate of fistula formation was 18.1%, whereas the rate of fistula requiring reoperation was 4.2%, significantly lower than rates in our historic cohort (34.6% and 14.8%, respectively; P = 0.02 and 0.01). Postoperative hypothyroidism and recurrent clinical stage predicted fistula requiring reoperation in multivariate analysis; other acute phase reactants were not predictive. There were no observed adverse events related to levothyroxine supplementation. CONCLUSIONS: Postoperative intravenous levothyroxine supplementation reduced rates of acute hypothyroidism, fistula formation, and fistula requiring reoperation in patients undergoing salvage total laryngectomy without adverse effects. Intravenous levothyroxine is a viable strategy to reduce wound complications in this high-risk patient population.

RESUMO

OBJECTIVE: Traditional hospital accounting fails to provide an accurate cost of complex surgical care. Here we describe the application of time-driven activity-based costing (TDABC) to characterize costs of head and neck oncologic procedures involving free tissue transfer. STUDY DESIGN: Retrospective cohort study. SETTING: Single tertiary academic medical center. METHODS: An analysis of head and neck oncologic procedures involving microvascular free flap reconstruction from 2018 to 2020 (n = 485) was performed using TDABC methodology to measure cost across operative case and postoperative admission, using quantity of time and cost per unit of each resource to characterize resource utilization. Univariate and generalized linear mixed models were used to examine associations between patient and hospital characteristics and cost of care delivery. RESULTS: The total cost of care delivery was $41,905.77 ± 21,870.27 with operating room (OR) supplies accounting for only 10% of the total cost. Multivariable analyses identified significant cost drivers including operative time, postoperative length of stay, number of return trips to the OR, postoperative complication, number of free flaps performed, and patient transfer from another hospital or via emergency department admission (P < .05). CONCLUSION: Operative time and postoperative length of stay, but not operative supplies, were primary drivers of cost of care for head and neck oncology cases involving free tissue transfer. TDABC offers granular cost characterization to inform cost optimization through unused capacity identification and postoperative admission efficiencies.

RESUMO

PURPOSE: Locoregionally advanced HPV+ oropharyngeal squamous cell carcinoma (OPSCC) has excellent cure rates, although current treatment regimens are accompanied by acute and long-term toxicities. We designed a phase II deescalation trial for patients with HPV+ OPSCC to evaluate the feasibility of an upfront neck dissection to individualize definitive treatment selection to improve the quality of life without compromising survival. PATIENTS AND METHODS: Patients with T1-3, N0-2 HPV+ OPSCC underwent an upfront neck dissection with primary tumor biopsy. Arm A included patients with a single lymph node less than six centimeters, with no extracapsular spread (ECS) and no primary site adverse features underwent transoral surgery. Arm B included patients who had two or more positive lymph nodes with no ECS, or those with primary site adverse features were treated with radiation alone. Arm C included patients who had ECS in any lymph node and were treated with chemoradiation. The primary endpoint was quality of life at 1 year compared with a matched historical control. RESULTS: Thirty-four patients were enrolled and underwent selective neck dissection. On the basis of pathologic characteristics, 14 patients were assigned to arm A, 10 patients to arm B, and 9 to arm C. A significant improvement was observed in Head and Neck Quality of Life (HNQOL) compared with historical controls (-2.6 vs. -11.9, P = 0.034). With a median follow-up of 37 months, the 3-year overall survival was 100% and estimated 3-year estimated progression-free survival was 96% [95% confidence interval (CI), 76%-99%]. CONCLUSIONS: A neck dissection-driven treatment paradigm warrants further research as a deintensification strategy.

RESUMO

OBJECTIVE: To determine the association between preoperative thyroid hormone replacement and complications following major abdominal surgery. METHODS: A retrospective case series was performed of patients enrolled in the Michigan Surgical Quality Collaborative (MSQC) who underwent major abdominal surgery at an academic institution over a 10-year period. The principal explanatory variable was preoperative thyroid hormone replacement. Primary outcomes were morbidity, mortality and length of stay. RESULTS: 2700 patients were identified. On multivariate analysis correcting for established predictors of operative morbidity, patients on preoperative thyroid replacement had a 1.5- fold increased risk of serious morbidity(p â€‹= â€‹0.01), and a 1.7- fold greater risk for serious sepsis(p â€‹= â€‹0.04). Thyroid replacement was associated with longer length of stay(p â€‹< â€‹0.001). While there was a high degree of missing data for surgical approach (31.1 â€‹% missing data), results suggest that patients on thyroid hormone replacement were more likely to undergo an open rather than minimally invasive surgery(p â€‹< â€‹0.01). Open surgery was associated with greater risk of serious morbidity(p â€‹= â€‹0.003) and longer length of stay(p â€‹< â€‹0.001). CONCLUSIONS: Preoperative thyroid hormone replacement independently predicts operative morbidity and length of stay following major abdominal surgery.

RESUMO

Every year in the United States, hundreds of shortages of life-saving, essential drugs impact patients and health care workers. While otolaryngologists may be shielded from these relative to other specialties, there is still a significant clinical impact with potentially dangerous consequences. Shortages of local anesthetics lead to increased costs, labor demands, and risk of medical errors. Shortages of cisplatin and carboplatin, workhorses in head and neck oncology, may leave patients without proven alternative therapies. The economic and geopolitical challenges that provoke these shortages are well described. So too are potential solutions at the national, regional, and local levels. Otolaryngologists have a responsibility to contribute to coordinated responses to drug shortages to protect and advocate for their current and future patients.

RESUMO

BACKGROUND: Cranial nerve injury is an uncommon but significant complication of neck dissection. We examined the association between the use of intraoperative neuromuscular blockade and iatrogenic cranial nerve injury during neck dissection. METHODS: This was a single-center, retrospective, electronic health record review. Study inclusion criteria stipulated patients > 18 years who had ≥ 2 neck lymphatic levels dissected for malignancy under general anesthesia with a surgery date between 2008 - 2018. Use of neuromuscular blockade during neck dissection was the primary independent variable. This was defined as any use of rocuronium, cisatracurium, or vecuronium upon anesthesia induction without reversal with sugammadex prior to surgical incision. Univariate tests were used to compare variables between those patients with, and those without, iatrogenic cranial nerve injury. Multivariable logistic regression determined predictors of cranial nerve injury and was performed incorporating Firth's estimation given low prevalence of the primary outcome. RESULTS: Our cohort consisted of 925 distinct neck dissections performed in 897 patients. Neuromuscular blockade was used during 285 (30.8%) neck dissections. Fourteen instances (1.5% of surgical cases) of nerve injury were identified. On univariate logistic regression, use of neuromuscular blockade was not associated with iatrogenic cranial nerve injury (OR: 1.73, 95% CI: 0.62 - 4.86, p = 0.30). There remained no significant association on multivariable logistic regression controlling for patient age, sex, weight, ASA class, paralytic dose, history of diabetes, stroke, coronary artery disease, carotid atherosclerosis, myocardial infarction, and cardiac arrythmia (OR: 1.87, 95% CI: 0.63 - 5.51, p = 0.26). CONCLUSIONS: In this study, use of neuromuscular blockade intraoperatively during neck dissection was not associated with increased rates of iatrogenic cranial nerve injury. While this investigation provides early support for safe use of neuromuscular blockade during neck dissection, future investigation with greater power remains necessary.

RESUMO

Background: In recent years, interest in prognostic calculators for predicting patient health outcomes has grown with the popularity of personalized medicine. These calculators, which can inform treatment decisions, employ many different methods, each of which has advantages and disadvantages. Methods: We present a comparison of a multistate model (MSM) and a random survival forest (RSF) through a case study of prognostic predictions for patients with oropharyngeal squamous cell carcinoma. The MSM is highly structured and takes into account some aspects of the clinical context and knowledge about oropharyngeal cancer, while the RSF can be thought of as a black-box non-parametric approach. Key in this comparison are the high rate of missing values within these data and the different approaches used by the MSM and RSF to handle missingness. Results: We compare the accuracy (discrimination and calibration) of survival probabilities predicted by both approaches and use simulation studies to better understand how predictive accuracy is influenced by the approach to (1) handling missing data and (2) modeling structural/disease progression information present in the data. We conclude that both approaches have similar predictive accuracy, with a slight advantage going to the MSM. Conclusions: Although the MSM shows slightly better predictive ability than the RSF, consideration of other differences are key when selecting the best approach for addressing a specific research question. These key differences include the methods' ability to incorporate domain knowledge, and their ability to handle missing data as well as their interpretability, and ease of implementation. Ultimately, selecting the statistical method that has the most potential to aid in clinical decisions requires thoughtful consideration of the specific goals.

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

Our nation faces contentious questions regarding reproductive rights and access to abortion which have long been viewed as beyond the scope of otolaryngology. The broad implications of the recent Supreme Court ruling in Dobbs v Jackson Women's Health Organization (Jackson) impact all people who are, or can become, pregnant and their health care providers. The consequences for otolaryngologists are thus far-reaching and poorly understood. Here we describe how the post-Dobbs landscape is relevant to the practice of otolaryngology and offer suggestions for how otolaryngologists can best respond, prepare, and support their patients in this tenuous political landscape.

RESUMO

BACKGROUND: Inter-hospital patient transfers to hospitals with greater resource availability and expertise may improve clinical outcomes. However, there is little guidance regarding how patient transfer requests should be prioritized when hospital resources become scarce. OBJECTIVE: To understand the experiences of healthcare workers involved in the process of accepting inter-hospital patient transfers during a pandemic surge and determine factors impacting inter-hospital patient transfer decision-making. DESIGN: We conducted a qualitative study consisting of semi-structured interviews between October 2021 and February 2022. PARTICIPANTS: Eligible participants were physicians, nurses, and non-clinician administrators involved in the process of accepting inter-hospital patient transfers. Participants were recruited using maximum variation sampling. APPROACH: Semi-structured interviews were conducted with healthcare workers across Michigan. KEY RESULTS: Twenty-one participants from 15 hospitals were interviewed (45.5% of eligible hospitals). About half (52.4%) of participants were physicians, 38.1% were nurses, and 9.5% were non-clinician administrators. Three domains of themes impacting patient transfer decision-making emerged: decision-maker, patient, and environmental factors. Decision-makers described a lack of guidance for transfer decision-making. Patient factors included severity of illness, predicted chance of survival, need for specialized care, and patient preferences for medical care. Decision-making occurred within the context of environmental factors including scarce resources at accepting and requesting hospitals, organizational changes to transfer processes, and alternatives to patient transfer including use of virtual care. Participants described substantial moral distress related to transfer triaging. CONCLUSIONS: A lack of guidance in transfer processes may result in considerable variation in the patients who are accepted for inter-hospital transfer and in substantial moral distress among decision-makers involved in the transfer process. Our findings identify potential organizational changes to improve the inter-hospital transfer process and alleviate the moral distress experienced by decision-makers.

RESUMO

PURPOSE: 18F-Fluorodeoxyglucose positron emission tomography (FDG-PET) parameters are prognostic of oncologic outcomes in human papillomavirus-associated oropharyngeal squamous cell carcinoma (OPSCC). We used FDG-PET imaging biomarkers to select patients for de-escalated chemoradiotherapy (CRT), hypothesizing that acute toxicity will be improved with de-escalation. METHODS AND MATERIALS: This is a planned interim initial feasibility and acute toxicity report from a phase 2, prospective, nonrandomized study, which enrolled patients with stage I-II p16+ OPSCC. All patients started definitive CRT to 70 Gy in 35 fractions, and those who met de-escalation criteria on midtreatment FDG-PET at fraction 10 completed treatment at 54 Gy in 27 fractions. We report the acute toxicity and patient-reported outcomes for 59 patients with a minimum follow-up of 3 months. RESULTS: There were no statistically significant differences between baseline patient characteristics in the standard and de-escalated cohorts. There were 28 of 59 (47.5%) patients who met FDG-PET de-escalation criteria and collectively received 20% to 30% less dose to critical organs at risk known to affect toxicity. At 3 months posttreatment, patients who received de-escalated CRT lost significantly less weight (median, 5.8% vs 13.0%; P < .001), had significantly less change from baseline in penetration-aspiration scale score (median, 0 vs 1; P = .018), and had significantly fewer aspiration events on repeat swallow study (8.0% vs 33.3%, P = .037) compared with patients receiving standard CRT. CONCLUSIONS: Approximately half of patients with early-stage p16+ OPSCC are selected for de-escalation of definitive CRT using midtreatment FDG-PET biomarkers, which resulted in significantly improved rates of observed acute toxicity. Further follow-up is ongoing and will be required to determine whether this de-escalation approach preserves the favorable oncologic outcomes for patients with p16+ OPSCC before adoption.

RESUMO

SUMMARY: As more academic institutions with surgical residency training programs begin to offer gender-affirming surgery, issues of trainee conscientious objection related to participation in these patient encounters may arise. In this article, the authors discuss their institutional experience with residents' conscientious objection to involvement in gender-affirming surgery. Although there are ethical arguments for and against conscientious objection, current U.S. federal policy grants all health care workers conscientious objector status upon their request. Recommendations are offered for other institutions that may experience similar situations regarding conscientious objection to gender-affirming care or to other aspects of plastic and reconstructive surgery.

RESUMO

OBJECTIVES: In an evolving era of immunotherapeutic options for persistent or recurrent laryngeal squamous cell carcinoma (LSCC), there is a need for improved biomarkers of treatment response and survival to inform optimal treatment selection and prognostication. Herein, our primary objective was to explore correlations between tumor infiltrating lymphocytes (TILs) and PD-L1 Combined Positive Score (CPS). Secondarily, we sought to explore their combined association with survival outcomes in patients with persistent or recurrent LSCC treated with salvage surgery. MATERIALS AND METHODS: This was a retrospective cohort study at a single academic medical center. Immunohistochemistry staining for TILs and PD-L1 was performed on a tissue microarray of persistent or recurrent LSCC pathologic specimens. Correlations between TIL subsets and PD-L1 CPS were examined using Pearson's correlation coefficient and survival outcomes were analyzed with the Kaplan-Meier method and log-rank tests. RESULTS: Only CD103+ TILs showed a statistically significant, weakly-positive correlation with PD-L1 CPS (r2 = 0.264, p < 0.015). No other TIL subsets correlated with PD-L1 CPS in our cohort. The most favorable survival outcomes were seen in patients with pathologic N0 tumors showing high CD103+ TILs and/or high PD-L1 CPS staining. CONCLUSION: Among patients with persistent or recurrent LSCC, CD103+ TILs only modestly correlated with PD-L1 CPS. A combined biomarker score incorporating CD103+ TILs and PD-L1 CPS greatly enhanced survival discrimination. This model may have additional utility in predicting the clinical benefit of immunotherapies in persistent or recurrent LSCC in the future.

RESUMO

PURPOSE: We conducted a randomized phase II multicenter clinical trial to test the hypothesis that physiologic MRI-based radiotherapy (RT) dose escalation would improve the outcome of patients with poor prognosis head and neck cancer. PATIENTS AND METHODS: MRI was acquired at baseline and at RT fraction 10 to create low blood volume/apparent diffusion coefficient maps for RT boost subvolume definition in gross tumor volume. Patients were randomized to receive 70 Gy (standard RT) or 80 Gy to the boost subvolume (RT boost) with concurrent weekly platinum. The primary endpoint was disease-free survival (DFS) with significance defined at a one-sided 0.1 level, and secondary endpoints included locoregional failure (LRF), overall survival (OS), comparison of adverse events and patient reported outcomes (PRO). RESULTS: Among 81 randomized patients, neither the primary endpoint of DFS (HR = 0.849, P = 0.31) nor OS (HR = 1.19, P = 0.66) was significantly improved in the RT boost arm. However, the incidence of LRF was significantly improved with the addition of the RT boost (HR = 0.43, P = 0.047). Two-year estimates [90% confidence interval (CI)] of the cumulative incidence of LRF were 40% (27%-53%) in the standard RT arm and 18% (10%-31%) in the RT boost arm. Two-year estimates (90% CI) for DFS were 48% (34%-60%) in the standard RT arm and 57% (43%-69%) in the RT boost arm. There were no significant differences in toxicity or longitudinal differences seen in EORTC QLQ30/HN35 subscales between treatment arms in linear mixed-effects models. CONCLUSIONS: Physiologic MRI-based RT boost decreased LRF without a significant increase in grade 3+ toxicity or longitudinal PRO differences, but did not significantly improve DFS or OS. Additional improvements in systemic therapy are likely necessary to realize improvements in DFS and OS.

RESUMO

Clinicians cannot always directly or effectively engage patients experiencing mental health crises. This article considers the common practice of relying upon law enforcement personnel to facilitate mental health checks and considers its implications for Black patients. An antiracist approach to decriminalizing acute exacerbations of mental illness requires clinicians' engagement in educating, training, and policymaking. This article recommends strategies for effective real-time communication before, during, and after a 911 call involving a person experiencing a mental health crisis.

RESUMO

BACKGROUND: The genomic frontier continues to revolutionize the practice of oncology. Advances in cancer biology from tumorigenesis to treatment resistance are driven by the molecular underpinnings of malignancy. The framing of precision oncology as both a clinical and research tool is constantly evolving and directly influences conversations between oncologists and their patients. Prior research has shown that patient-participants often have unmet or unrealistic expectations regarding the clinical utility of oncology research and genomic sequencing. This indicates the need for more in-depth investigation of how and why patients choose to participate in such research. OBJECTIVE: This study presents a qualitative ethical analysis to better understand patient and provider perspectives on enrollment in precision oncology research. METHODS: Paired semistructured interviews were conducted with patient-participants enrolled in a prospective head and neck precision oncology research platform, along with their oncology providers, at a National Cancer Institute-designated academic cancer center. RESULTS: There were three major themes that emerged from the analysis. (1) There are distinct and unique challenges with informed consent to precision medicine, chiefly involving the ability of both patient-participants and providers to effectively understand the science underlying the research. (2) The unique benefits of precision medicine enrollment are of paramount importance to patients considering enrollment. (3) Patient-participants have little concern for the risks of research enrollment, particularly in the context of a low-burden protocol. CONCLUSIONS: Patient-participants and their providers offer complementary and nuanced perspectives on their motivation to engage in precision oncology research. This reflects both the inherent promise and enthusiasm within the field, as well as the limitations and challenges of ensuring that both patient-participants and clinicians understand the complexities of the science involved.
