Oropharyngeal Cancer Staging Health Record Extraction Using Artificial Intelligence.

Importance: Accurate, timely, and cost-effective methods for staging oropharyngeal cancers are crucial for patient prognosis and treatment decisions, but staging documentation is often inaccurate or incomplete. With the emergence of artificial intelligence in medicine, data abstraction may be associated with reduced costs but increased efficiency and accuracy of cancer staging. Objective: To evaluate an algorithm using an artificial intelligence engine capable of extracting essential information from medical records of patients with oropharyngeal cancer and assigning tumor, nodal, and metastatic stages according to American Joint Committee on Cancer eighth edition guidelines. Design, Setting, and Participants: This retrospective diagnostic study was conducted among a convenience sample of 806 patients with oropharyngeal squamous cell carcinoma. Medical records of patients with staged oropharyngeal squamous cell carcinomas who presented to a single tertiary care center between January 1, 2010, and August 1, 2020, were reviewed. A ground truth cancer stage dataset and comprehensive staging rule book consisting of 135 rules encompassing p16 status, tumor, and nodal and metastatic stage were developed. Subsequently, 4 distinct models were trained: model T (entity relationship extraction) for anatomical location and invasion state, model S (numerical extraction) for lesion size, model M (sequential classification) for metastasis detection, and a p16 model for p16 status. For validation, results were compared against ground truth established by expert reviewers, and accuracy was reported. Data were analyzed from March to November 2023. Main Outcomes and Measures: The accuracy of algorithm cancer stages was compared with ground truth. Results: Among 806 patients with oropharyngeal cancer (mean [SD] age, 63.6 [10.6] years; 651 males [80.8%]), 421 patients (52.2%) were positive for human papillomavirus. The artificial intelligence engine achieved accuracies of 55.9% (95% CI, 52.5%-59.3%) for tumor, 56.0% (95% CI, 52.5%-59.4%) for nodal, and 87.6% (95% CI, 85.1%-89.7%) for metastatic stages and 92.1% (95% CI, 88.5%-94.6%) for p16 status. Differentiation between localized (stages 1-2) and advanced (stages 3-4) cancers achieved 80.7% (95% CI, 77.8%-83.2%) accuracy. Conclusion and Relevance: This study found that tumor and nodal staging accuracies were fair to good and excellent for metastatic stage and p16 status, with clinical relevance in assigning optimal treatment and reducing toxic effect exposures. Further model refinement and external validation with electronic health records at different institutions are necessary to improve algorithm accuracy and clinical applicability.

Length of Stay Prediction Models for Oral Cancer Surgery: Machine Learning, Statistical and ACS-NSQIP.

OBJECTIVE: Accurate prediction of hospital length of stay (LOS) following surgical management of oral cavity cancer (OCC) may be associated with improved patient counseling, hospital resource utilization and cost. The objective of this study was to compare the performance of statistical models, a machine learning (ML) model, and The American College of Surgeons National Surgical Quality Improvement Program's (ACS-NSQIP) calculator in predicting LOS following surgery for OCC. MATERIALS AND METHODS: A retrospective multicenter database study was performed at two major academic head and neck cancer centers. Patients with OCC who underwent major free flap reconstructive surgery between January 2008 and June 2019 surgery were selected. Data were pooled and split into training and validation datasets. Statistical and ML models were developed, and performance was evaluated by comparing predicted and actual LOS using correlation coefficient values and percent accuracy. RESULTS: Totally 837 patients were selected with mean patient age being 62.5 ± 11.7 [SD] years and 67% being male. The ML model demonstrated the best accuracy (validation correlation 0.48, 4-day accuracy 70%), compared with the statistical models: multivariate analysis (0.45, 67%) and least absolute shrinkage and selection operator (0.42, 70%). All were superior to the ACS-NSQIP calculator's performance (0.23, 59%). CONCLUSION: We developed statistical and ML models that predicted LOS following major free flap reconstructive surgery for OCC. Our models demonstrated superior predictive performance to the ACS-NSQIP calculator. The ML model identified several novel predictors of LOS. These models must be validated in other institutions before being used in clinical practice. LEVEL OF EVIDENCE: Level 3 Laryngoscope, 2024.

Reconstruction for Salvage Laryngectomy With Limited Pharyngectomy.

Importance: Closure technique for optimization of postoperative and functional outcomes following salvage laryngectomy remains an area of debate among head and neck surgeons. Objective: To investigate the association of salvage laryngectomy closure technique with early postoperative and functional outcomes. Design, Setting, and Participants: This retrospective cohort study included patients from 17 academic, tertiary care centers who underwent total laryngectomy with no or limited pharyngectomy after completing a course of definitive radiotherapy or chemoradiotherapy with curative intent between January 2011 and December 2016. Patients with defects not amenable to primary closure were excluded. Data were analyzed from February 14, 2021, to January 29, 2024. Exposures: Total laryngectomy with and without limited pharyngectomy, reconstructed by primary mucosal closure (PC), regional closure (RC), or free tissue transfer (FTT). Main Outcomes and Measures: Patients were stratified on the basis of the pharyngeal closure technique. Perioperative and long-term functional outcomes were evaluated with bivariate analyses. A multivariable regression model adjusted for historical risk factors for pharyngocutaneous fistula (PCF) was used to assess risk associated with closure technique. Relative risks (RRs) with 95% CIs were determined. Results: The study included 309 patients (256 [82.8%] male; mean age, 64.7 [range, 58.0-72.0] years). Defects were reconstructed as follows: FTT (161 patients [52.1%]), RC (64 [20.7%]), and PC (84 [27.2%]). A PCF was noted in 36 of 161 patients in the FTT group (22.4%), 25 of 64 in the RC group (39.1%), and 29 of 84 in the PC group (34.5%). On multivariable analysis, patients undergoing PC or RC had a higher risk of PCF compared with those undergoing FTT (PC: RR, 2.2 [95% CI, 1.1-4.4]; RC: RR, 2.5 [95% CI, 1.3-4.8]). Undergoing FTT was associated with a clinically meaningful reduction in risk of PCF (RR, 0.6; 95% CI, 0.4-0.9; number needed to treat, 7). Subgroup analysis comparing inset techniques for the RC group showed a higher risk of PCF associated with PC (RR, 1.8; 95% CI, 1.1-3.0) and predominately pectoralis myofascial flap with onlay technique (RR, 1.9; 95% CI, 1.2-3.2), but there was no association of pectoralis myocutaneous flap with cutaneous paddle interposition with PCF (RR, 1.2; 95% CI, 0.5-2.8) compared with FTT with cutaneous inset. There were no clinically significant differences in functional outcomes between the groups. Conclusion and Relevance: In this study of patients with limited pharyngeal defects, interpositional fasciocutaneous closure technique was associated with reduced risk of PCF in the salvage setting, which is most commonly achieved by FTT in academic practices. Closure technique was not associated with functional outcomes at 1 and 2 years postoperatively.

Stereotactic body radiotherapy for distant metastases to the head and neck.

PURPOSE: To report clinical outcomes for patients with metastatic disease to the head and neck (HN) treated with stereotactic body radiation therapy (SBRT). METHODS: A retrospective review of patients treated with SBRT to HN sites from 2012 to 2020 was conducted. Treatment indications included the following: oligometastases, oligoprogression, and control a dominant area of progression (DAP). Kaplan-Meier method was used to estimate local control (LC), regional control (RC), overall survival (OS), and progression-free survival (PFS). Univariable (UVA) and multivariable analyses (MVA) were performed. Grade 3-4 acute and late toxicities were reported by the Common Terminology Criteria for Adverse Events v5.0. RESULTS: Fifty-six patients (58 lesions) were analysed with a median follow-up of 16 months. Primary sites included lung (25.0%), kidney (19.6%), breast (19.6%) and other (35.8%). SBRT indications were as follows: oligometastases (42.9%), oligoprogression (19.6%) and local control of a dominant area of progression (37.5%). Most patients received SBRT to a single neck node (n = 47, 81.0%). Median SBRT dose was 40 Gy (range 25-50 Gy) in five fractions, with a median biologically effective dose (BED10) of 72 Gy (range 37.5-100 Gy). One- and 2-year LC and RC rates were 97.6% and 72.7% as well as 100% and 86.7%, respectively. Median OS was 19.2 months (95% [CI] 14.8-69.4), and median PFS was 7.4 months (95% [CI] 5.2-11.9). The 1-year OS and PFS rates for oligometastases, oligoprogression and DAP were 95.8%, 63.6% and 38.1% (p = 0.0039) as well as 56.5%, 27.3% and 19.1% (p = 0.0004), respectively. On MVA, treatment indication and histology were predictive for OS, while indication and prior systemic therapy were predictive for PFS. Cumulative late grade 3 + toxicity rate was 11.3%, without grade 5 events. CONCLUSION: The use of SBRT for metastatic disease to the HN provided excellent LC rates with low rates of regional failure and an acceptable toxicity profile, highlighting its utility in these patients. Patients with oligometastatic disease had better OS and PFS than others.

Intraoperative Ultrasound for Removal of a Fishbone Foreign Body Embedded in the Tongue.

Background: Ultrasound (U/S) is a dynamic imaging modality with many applications in medicine. In Otolaryngology, U/S is used routinely in the clinic with several evolving applications intraoperatively. Case Report. A 53-year-old male presented to the emergency department with dysphagia, odynophagia, hoarseness, and sensation of foreign body after ingesting fish. A CT scan identified an approximately 2 cm horizontally-oriented foreign body consistent with a fishbone embedded in the left posterolateral tongue. Intraoperative U/S was used to localize and remove the fishbone without complications. Results: The patient recovered well after surgery and was discharged home on postoperative day 2. No residual foreign body was found on the repeat CT scan. Conclusion: Our case demonstrates the effectiveness of intraoperative U/S for removal of fishbone foreign bodies from the tongue and serves to inspire future applications of this modality in Otolaryngology.

Lymph node yield: Impact on oncologic outcomes in oral cavity cancer.

BACKGROUND: Lymph node metastases are associated with poor prognosis in oral cavity squamous cell carcinoma (OCSCC). In other cancers, clinical guidelines on the number of lymph nodes removed during primary surgery, lymph node yield (LNY), exist. Here, we evaluated the prognostic capacity of LNY on regional failure, locoregional recurrence, and disease-free survival (DFS) in patients with OCSCC treated by primary neck surgery. METHODS: This retrospective cohort study took place at Sunnybrook Health Sciences Centre in Toronto, Canada and involved a chart review of all adult patients with treatment-naive OCSCC undergoing primary neck dissection. For each outcome, we first used the maximally selected rank statistics and an optimism-corrected concordance to identify an optimal threshold of LNY. We then used a multivariable Cox proportional hazards model to assess the association between high LNY (>threshold) and each outcome. RESULTS: Among the 579 patients with OCSCC receiving primary neck dissection, 61.7% (n = 357) were male with a mean age of 62.9 years (standard deviation: 13.1) at cancer diagnosis. When adjusting for sociodemographic and clinical factors, LNY >15 was significantly associated with improved DFS (adjusted HR [aHR]: 0.73, 95% CI: 0.54-0.98), locoregional recurrence (aHR: 0.68, 95% CI: 0.49-0.95), and regional failure (aHR: 0.61, 95% CI: 0.39-0.93). CONCLUSIONS: Our study findings suggested high LNY to be a strong independent predictor of various patient-level quality of surgical care metrics. The optimal LNY we found (15) was lower than the conventionally recommended (18), which calls for further research to establish validity in practice.

Differences in both expression and protein activity contribute to the distinct functions of AINTEGUMENTA compared with AINTEGUMENTA-LIKE 5 and AINTEGUMENTA-LIKE 7.

Three members of the Arabidopsis AINTEGUMENTA-LIKE/PLETHORA (AIL/PLT) transcription factor family, AIL5/PLT5, AIL6/PLT3, and AIL7/PLT7, exhibit partially overlapping roles with AINTEGUMENTA (ANT) during flower development. Loss of ANT function alone results in smaller floral organs and female sterility indicating that some ANT functions cannot be provided by these related transcription factors. Previously, we showed that expression of AIL6 at the same levels and spatial pattern as ANT could largely rescue the defects of ant mutants. This suggested that the functional differences between ANT and AIL6 were primarily a consequence of expression differences. Here, we investigated the functional differences between ANT and both AIL5 and AIL7 by expressing these two AILs under the control of the ANT promoter. We found that only ANT:gAIL5 lines with much higher amounts of AIL5 mRNA as compared with ANT could compensate for loss of ANT function. ANT:gAIL7 lines with AIL7 mRNA levels similar to those of ANT were able to rescue some but not all aspects of the ant mutant phenotype. Thus, expression differences alone cannot explain the functional differences between ANT and these two related proteins. Studies in yeast show that AIL5 and AIL7 have lower transcriptional activation activities as compared with ANT and AIL6 when bound to the consensus ANT DNA binding site. Our results suggest that differences in both expression and protein activity contribute to the functional specificity of ANT compared with AIL5 and AIL7.

Oncologic Significance of Therapeutic Delays in Patients With Oral Cavity Cancer.

Importance: Oral cavity cancer often requires multidisciplinary management, subjecting patients to complex therapeutic trajectories. Prolonged treatment intervals in oral cavity cancer have been associated with poor oncological outcomes, but there has yet to be a study investigating treatment times in Canada. Objective: To report treatment delays for patients with oral cavity cancer in Canada and evaluate the outcomes of treatment delays on overall survival. Design, Setting, and Participants: This multicenter cohort study was performed at 8 Canadian academic centers from 2005 to 2019. Participants were patients with oral cavity cancer who underwent surgery and adjuvant radiation therapy. Analysis was performed in January 2023. Main Outcomes and Measures: Treatment intervals evaluated were surgery to initiation of postoperative radiation therapy interval (S-PORT) and radiation therapy interval (RTI). The exposure variables were prolonged intervals, respectively defined as index S-PORT greater than 42 days and RTI greater than 46 days. Patient demographics, Charlson Comorbidity Index, smoking status, alcohol status, and cancer staging were also considered. Univariate (log rank and Kaplan-Meier) and multivariate (Cox regression) analyses were performed to determine associations with overall survival (OS). Results: Overall, 1368 patients were included; median (IQR) age at diagnosis was 61 (54-70) years, and 896 (65%) were men. Median (IQR) S-PORT was 56 (46-68) days, with 1093 (80%) patients waiting greater than 42 days, and median (IQR) RTI was 43 (41-47) days, with 353 (26%) patients having treatment time interval greater than 46 days. There were variations in treatment time intervals between institutions for S-PORT (institution with longest vs shortest median S-PORT, 64 days vs 48 days; η2 = 0.023) and RTI (institution with longest vs shortest median RTI, 44 days vs 40 days; η2 = 0.022). Median follow-up was 34 months. The 3-year OS was 68%. In univariate analysis, patients with prolonged S-PORT had worse survival at 3 years (66% vs 77%; odds ratio 1.75; 95% CI, 1.27-2.42), whereas prolonged RTI (67% vs 69%; odds ratio 1.06; 95% CI, 0.81-1.38) was not associated with OS. Other factors associated with OS were age, Charlson Comorbidity Index, alcohol status, T category, N category, and institution. In the multivariate model, prolonged S-PORT remained independently associated with OS (hazard ratio, 1.39; 95% CI, 1.07-1.80). Conclusions and Relevance: In this multicenter cohort study of patients with oral cavity cancer requiring multimodal therapy, initiation of radiation therapy within 42 days from surgery was associated with improved survival. However, in Canada, only a minority completed S-PORT within the recommended time, whereas most had an appropriate RTI. An interinstitution variation existed in terms of treatment time intervals. Institutions should aim to identify reasons for delays in their respective centers, and efforts and resources should be directed toward achieving timely completion of S-PORT.

Cine MRI-based analysis of intrafractional motion in radiation treatment planning of head and neck cancer patients.

PURPOSE/OBJECTIVE(S): To investigate intrafraction motion of (HN) target volumes and to determine patient-specific planning target volume (PTV) margins. MATERIALS/METHODS: MR-cine imaging was performed for radiation treatment planning in HN cancer patients treated with definitive EBRT (n = 62) or SBRT (n = 4) on a 1.5 T MRI between 2017-2019. Dynamic MRI scans (sagittal orientation, 2 × 82 × 7 mm3 resolution), ranging from 3-5 min and 900-1500 images, were acquired. The position of the maximum tumor displacement along each direction in the anterior/posterior (A/P) and superior/inferior (S/I) position was recorded and analyzed to determine average PTV margins. RESULTS: Primary tumor sites (n = 66) were oropharynx (n = 39), larynx (n = 24) and hypopharynx (n = 3). PTV margins for A/P/S/I positions were 4.1/4.4/5.0/6.2 mm and 4.9/4.3/6.7/7.7 mm for oropharyngeal and laryngeal/hypopharyngeal cancers when accounting for all motion. V100 for PTV was calculated and compared to the original plans. The mean drop in PTV coverage was in most cases under 5%. For a subset of patients with 3 mm plans available, V100 for PTV had more substantial decreases in coverage averaging 8.2% - and 14.3% for oropharyngeal and laryngeal/hypopharynx plans, respectively. CONCLUSION: The use of MR-cine in treatment planning allows for quantification of tumor motion during swallow and resting periods and should be accounted for during treatment planning. With motion considered, the derived margins may exceed the commonly used 3-5 mm PTV margins. Quantification and analysis of tumor and patient-specific PTV margins is a step towards real-time MRI guidance adaptive radiotherapy.

Understanding compassionate care from the patient perspective: Highlighting the experience of head and neck cancer care.

Objectives: To address the knowledge gap in the practice of compassionate healthcare by elucidating patient perspectives on compassion, empathy, and sympathy. Methods: Semi-structured telephone interviews were conducted at two time points with patients undergoing head and neck cancer treatment. Questions explored participants' understanding of compassion, sympathy, and empathy, as they relate to each other and to healthcare. Interviewers manually recorded responses. Qualitative exploratory methods were used to analyze data; inductive line-by-line coding was conducted to develop primary codes. Themes emerged through categorization of codes. Results: Ninety-five interviews conducted with 63 participants across two time points revealed four major themes - Compassion-vs-Empathy-vs-Sympathy, Coping Methods, Showing Care, and Nature of Interaction - encompassing seven categories, with a total of 24 codes. Codes were consistent across time points, except for two new codes, "positivity" and "personalized" emerging during follow-up interviews. Conclusions: Patient narrative from this study supported the concept that compassion is multidimensional and enabled several dimensions to be identified, highlighting the importance of patient perspectives in improving the provision of compassionate healthcare. Findings should be considered in future training and practice.

Surgeon Thyroidectomy Case Volume Impacts Disease-free Survival in the Management of Thyroid Cancer.

OBJECTIVES: To assess the association between surgeons thyroidectomy case volume and disease-free survival (DFS) for patients with well-differentiated thyroid cancer (WDTC). A secondary objective was to assess a surgeon volume cutoff to optimize outcomes in those with WDTC. We hypothesized that surgeon volume will be an important predictor of DFS in patients with WDTC after adjusting for hospital volume and sociodemographic and clinical factors. METHODS: In this retrospective population-based cohort study, we identified WDTC patients in Ontario, Canada, who underwent thyroidectomy confirmed by both hospital-level and surgeon-level administrative data between 1993 and 2017 (N = 37,233). Surgeon and hospital volumes were calculated based on number of cases performed in the year prior by the physician and at an institution performing each case, respectively and divided into quartiles. A multilevel hierarchical Cox regression model was used to estimate the effect of volume on DFS. RESULTS: A crude model without patient or treatment characteristics demonstrated that both higher surgeon volume quartiles (p < 0.001) and higher hospital volume quartiles (p < 0.001) were associated with DFS. After controlling for clustering and patient/treatment covariates and hospital volume, moderately low (18-39/year) and low (0-17/year) volume surgeons (hazard ratios [HR]: 1.23, 95% confidence interval [CI]: 1.09-1.39 and HR: 1.34, 95% CI: 1.17-1.53 respectively) remained an independent statistically significant negative predictor of DFS. CONCLUSION: Both high-volume surgeons and hospitals are predictors of better DFS in patients with WDTC. DFS is higher among surgeons performing more than 40 thyroidectomies a year. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:S1-S15, 2023.

Parathyroid hormone-driven algorithms after thyroid surgery: Not one-size-fits-all.

BACKGROUND: Underreported variation in parathyroid hormone (PTH) assays exists. Using quality improvement methods, we aimed to develop an institution-specific PTH-based protocol to predict hypocalcemia after thyroidectomy. METHODS: We retrospectively reviewed patients who underwent total/completion thyroidectomy. A receiver operating curve (ROC) determined postoperative PTH cut-offs predictive of hypocalcemia. The stakeholders developed PTH-driven calcium management guidelines. Post-implementation outcomes were prospectively measured. RESULTS: Pre-implementation, 95 patients were assessed. PTH ≤1.5 pmol/L (14.1 pg/ml) predicted hypocalcemia (96%sensitivity), and ≥2.8 pmol/L (26.4 pg/ml) predicted normocalcemia (99%specificity) (area under curve = 0.97, SEM = 0.018). PTH on the day of and morning after surgery were identically predictive. Post-implementation, 64 patients were assessed. Hypocalcemia occurred with PTH >2.8 pmol/L in 2 cases (3.1%). Calcium over-prescribing decreased from 13.7% to 3.1% (p = 0.06). Length of stay (LOS) > 2 nights decreased from 13% to 3.1% (p = 0.05). CONCLUSION: A PTH-driven calcium management protocol post-thyroidectomy effectively reduces unnecessary calcium replacement and LOS. Given the variability in PTH assays, each institution may need to use individual cut-offs.

Patient satisfaction with different types of craniofacial prostheses.

STATEMENT OF PROBLEM: A maxillofacial prosthesis represents an effective method of giving maxillofacial defects a positive esthetic appearance with minimal risk. However, studies of complications among prosthesis wearers are lacking. PURPOSE: The purpose of this cross-sectional study was to determine levels of patient satisfaction with various maxillofacial prostheses and retention types, as measured through a survey questionnaire package. MATERIAL AND METHODS: Patients treated at the Sunnybrook Health Sciences Center Craniofacial Prosthetics Unit (CPU) since 2015 were included. They had been treated according to a standardized protocol and answered a survey questionnaire package with the following sections: demographics, frequency of prosthesis usage, and the Toronto Outcome Measure for Craniofacial Prosthetics (TOMCP-27) survey addressing patient satisfaction. To be eligible for this study, patients must have been more than 18 years of age, in possession of a maxillofacial prosthesis, and received treatment at the Sunnybrook Health Sciences Center CPU since 2015. RESULTS: A total of 157 patients were eligible and contacted, of whom 51 agreed to participate in the survey. The study population was overall extremely satisfied with their maxillofacial prostheses. In 77.8% of the TOMCP-27 questions, the largest group of patients chose the answer demonstrating the highest level of satisfaction. Of all prosthesis types surveyed, patients with auricular prostheses reported the greatest rates of satisfaction, with the entire group having selected answers corresponding to the highest levels of overall satisfaction. However, patients with orbital prostheses were more likely to experience varying degrees of dissatisfaction, with 72% of the highest reported levels of dissatisfaction being from this prosthesis group. In addition, patients with osseointegrated implant-retained prostheses reported higher satisfaction levels with other retention methods, with the bar clasp group outperforming the magnetic coupling retention group. CONCLUSIONS: Patients experienced an excellent overall rate of satisfaction with their maxillofacial prostheses. Future development should focus on the continued development of osseointegrated methods, improved magnetic coupling, and improved prosthesis technology, especially for orbital prostheses.

Placement technique impacts gastrostomy tube-related complications amongst head and neck cancer patients.

OBJECTIVES: Percutaneous endoscopic gastrostomy (PEG) placement is essential for the provision of enteral nutrition in select head and neck cancer (HNC) patients. Minimally invasive tube placement is facilitated through one of two techniques, push or pull, but there have been conflicting results regarding safety profiles of these procedures. The objectives of this study were to determine the association of PEG insertion technique with gastrostomy tube complications, including stomal metastases. METHODS: A multi-institutional retrospective cohort study of patients with HNC undergoing PEG insertion by either the pull (gastroscope assisted) or push (fluoroscopy assisted) technique was performed. Tube-related complications included infection, dislodgement, deterioration, leak, and other. Adjusted analysis was performed via a multivariable logistic regression model. RESULTS: 1,575 patients were included across three institutions. Tube-related complications occurred in 36% of patients, the most common being peristomal leak (13%) and infection (16%). The push technique (OR 2.66, 95% CI: 1.42-4.97), and the presence of T4 disease (OR 4.62, 95% CI: 1.58-13.51), were associated with a greater risk of developing any tube-related complication. Infection rates were similar between pull and push cohorts. All detected stoma metastases occurred with the pull technique, with an overall prevalence of 0.32% amongst the cohort. CONCLUSIONS: The push technique is associated with a greater risk of developing any tube-related complication, but the rate of stomal metastases may be higher with the pull technique. There is potential for quality improvement measures to improve tube-related complications associated with either technique.

Assessment of Toxic Effects and Survival in Treatment Deescalation With Radiotherapy vs Transoral Surgery for HPV-Associated Oropharyngeal Squamous Cell Carcinoma: The ORATOR2 Phase 2 Randomized Clinical Trial.

Importance: The optimal approach for treatment deescalation in human papillomavirus (HPV)-related oropharyngeal squamous cell carcinomas (OPSCCs) is unknown. Objective: To assess a primary radiotherapy (RT) approach vs a primary transoral surgical (TOS) approach in treatment deescalation for HPV-related OPSCC. Design, Setting, and Participants: This international, multicenter, open-label parallel-group phase 2 randomized clinical trial was conducted at 9 tertiary academic cancer centers in Canada and Australia and enrolled patients with T1-T2N0-2 p16-positive OPSCC between February 13, 2018, and November 17, 2020. Patients had up to 3 years of follow-up. Interventions: Primary RT (consisting of 60 Gy of RT with concurrent weekly cisplatin in node-positive patients) vs TOS and neck dissection (ND) (with adjuvant reduced-dose RT depending on pathologic findings). Main Outcomes and Measures: The primary end point was overall survival (OS) compared with a historical control. Secondary end points included progression-free survival (PFS), quality of life, and toxic effects. Results: Overall, 61 patients were randomized (30 [49.2%] in the RT arm and 31 [50.8%] in the TOS and ND arm; median [IQR] age, 61.9 [57.2-67.9] years; 8 women [13.6%] and 51 men [86.4%]; 31 [50.8%] never smoked). The trial began in February 2018, and accrual was halted in November 2020 because of excessive toxic effects in the TOS and ND arm. Median follow-up was 17 months (IQR, 15-20 months). For the OS end point, there were 3 death events, all in the TOS and ND arm, including the 2 treatment-related deaths (0.7 and 4.3 months after randomization, respectively) and 1 of myocardial infarction at 8.5 months. There were 4 events for the PFS end point, also all in the TOS and ND arm, which included the 3 mortality events and 1 local recurrence. Thus, the OS and PFS data remained immature. Grade 2 to 5 toxic effects occurred in 20 patients (67%) in the RT arm and 22 (71%) in the TOS and ND arm. Mean (SD) MD Anderson Dysphagia Inventory scores at 1 year were similar between arms (85.7 [15.6] and 84.7 [14.5], respectively). Conclusions and Relevance: In this randomized clinical trial, TOS was associated with an unacceptable risk of grade 5 toxic effects, but patients in both trial arms achieved good swallowing outcomes at 1 year. Long-term follow-up is required to assess OS and PFS outcomes. Trial Registration: Clinicaltrials.gov Identifier: NCT03210103.

Using the Delphi Method to Elucidate Patient and Caregiver Experiences of Cancer Care.

Objective: Identify the most salient elements of the head and neck cancer (HNC) care experience described by patients and caregivers in focus group interviews. Methods: Three focus groups of patients and caregivers were facilitated by research assistants and clinicians. Open-ended guiding questions captured/elicited aspects of care that were appreciated, warranted improvement, or enhanced communication and information. A four-step Delphi process derived consensus among focus group facilitators (n = 5) regarding salient discussion points from focus group conversations. Results: Seven salient themes were identified: (1) information provision, (2) burden related to symptoms and treatment side effects, (3) importance of social support, (4) quality of care at both hospital and provider levels, (5) caring for the person, not just treating cancer, (6) social and emotional impact of HNC, and (7) stigma and insufficient information regarding human papillomavirus-related HNC. Conclusion: Participants reported varying needs and support preferences, a desire for individualized communication, and to feel cared for as both a person and a patient. Findings illuminate the intricate details underlying high-quality, compassionate, person-centered HNC cancer care.

Enhancing Outpatient Symptom Management in Patients With Head and Neck Cancer: A Qualitative Analysis.

IMPORTANCE: Patients with head and neck cancer manage a variety of symptoms at home on an outpatient basis. Clinician review alone often leaves patient symptoms undetected and untreated. Standardized symptom assessment using patient-reported outcomes (PROs) has been shown in randomized clinical trials to improve symptom detection and overall survival, although translation into real-world settings remains a challenge. OBJECTIVE: To better understand how patients with head and neck cancer cope with cancer-related symptoms and to examine their perspectives on standardized symptom assessment. DESIGN, PARTICIPANTS, AND SETTING: This was a qualitative analysis using semistructured interviews of patients with head and neck cancer and their caregivers from November 2, 2020, to April 16, 2021, at a regional tertiary center in Canada. Purposive sampling was used to recruit a varied group of participants (cancer subsite, treatment received, sociodemographic factors). Drawing on the Supportive Care Framework, a thematic approach was used to analyze the data. Data analysis was performed from November 2, 2020, to August 2, 2021. MAIN OUTCOMES AND MEASURES: Patient perception of ambulatory symptom management and standardized symptom assessment. RESULTS: Among 20 participants (median [range] age, 59.5 [33-74] years; 9 [45%] female; 13 [65%] White individuals), 4 themes were identified: (1) timely physical symptom management, (2) information as a tool for symptom management, (3) barriers to psychosocial support, and (4) external factors magnifying symptom burden. Participants' perceptions of standardized symptom assessment varied. Some individuals described the symptom monitoring process as facilitating self-reflection and symptom detection. Others felt disempowered by the process, particularly when symptom scores were inconsistently reviewed or acted on. CONCLUSIONS AND RELEVANCE: This qualitative analysis provides a novel description of head and neck cancer symptom management from the patient perspective. The 4 identified themes and accompanying recommendations serve as guides for enhanced symptom monitoring.

Stereotactic body radiotherapy for head and neck skin cancer.

AIM: To report outcomes of Stereotactic Body Radiotherapy (SBRT) for head and neck skin cancer (HNSC) patients treated at a high-volume center. MATERIALS: A retrospective review of HNSC SBRT patients from 2012 to 2019 was conducted. Kaplan-Meier method was used to estimate local control (LC), locoregional control (LRC) outside of SBRT field, overall survival (OS), progression-free survival (PFS) and late toxicity (LT). Univariate and multivariate analyses were performed. Grade 3-4 acute and late toxicities were reported by the Common Terminology Criteria for Adverse Events v5.0. RESULTS: One hundred and six medically unfit HNSC patients (112 lesions) were included. Median follow-up was 8 months. Median patient age at diagnosis was 86 years (range: 56-102 years). The majority of patients had advanced disease (overall stage III-IV [n = 90, 85%]) with median gross tumor volumes (GTV) of 31 cm3 (range: 17-56 cm3). Treated sites were: primary (n = 51), nodal (n = 47) or primary plus nodal (n = 8). SBRT doses ranged from 32-50 Gy delivered twice weekly in 4-6 fractions to the gross tumor volume (GTV). One and 2-year LC rates were 78% (69-88) and 67% (53-82), respectively. One-year LRC outside of SBRT field, OS, PFS and LT rates were 72% (62-84), 53% (43-65), 52% (40-62), and 7% (2-17), respectively. Thirty-three patients (31%) developed acute grade ≥ 3 treatment-related toxicity, most commonly dermatitis (n = 31). Nine patients (8%) experienced late grade ≥ 3 toxicity, including 7 grade 3 fibrosis, 1 grade 3 bone radionecrosis and 1 grade 4 skin ulceration. No treatment-related deaths (grade 5) were observed. CONCLUSION: SBRT provides durable disease control with acceptable toxicity for medically unfit high-risk HNSC patients unable to undergo standard of care curative treatment approaches.

A Population-Based Analysis of Outpatient Thyroidectomy: Safe and Under-Utilized.

OBJECTIVES/HYPOTHESIS: Performance of thyroidectomy on an outpatient basis has gained popularity although many jurisdictions have not shifted their practice despite a strong safety profile. We sought to assess the uptake and safety of outpatient thyroidectomy in Ontario. STUDY DESIGN: Retrospective cohort study. METHODS: This was a population-based retrospecive cohort of adult patients undergoing hemithyroidectomy or total thyroidectomy between 1993 and 2017 in Ontario, Canada. Outpatient surgery was defined as discharge home on the same day of surgery. Outcomes of interest include 30-day all cause death, hematoma, emergency department use, and readmission. To adjust for confounding, propensity scores were calculated. Logistic regression models with inverse probability of treatment weighting (IPTW) were then used to estimate the exposure-outcome relationship. RESULTS: The final cohort consisted of 81,199 patients: 8,442 underwent same day surgery and 72,757 were admitted. The proportion of patients undergoing outpatient thyroidectomy increased overtime (2.3% in 1993-1994 to 17.8% in 2016-2017). Factors associated with higher odds of outpatient thyroidectomy included: younger age, less material deprivation, less comorbidities, and higher surgeon volume. The absolute number of deaths (≤5) and hematomas (64, 0.8%) in the outpatient cohort was low. After IPTW adjustment, patients with outpatient management had lower odds of neck hematoma (OR 0.73[95CI% 0.58-0.93)], but higher odds of emergency department use (OR 1.67[95%CI 1.56-1.79]). CONCLUSIONS: Outpatient thyroidectomy is not associated with an increased mortality risk. Less than one in five patients undergo outpatient thyroidectomy in Ontario, despite a well-established safety profile. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:2625-2633, 2021.
