RESUMEN
BACKGROUND: Neoadjuvant chemotherapy (NAC) is used in head and neck squamous cell carcinoma (HNSCC) for downstaging advanced disease and decreasing distant metastasis (DM). To the authors' knowledge, no study has specifically examined the impact of a delayed time to surgery (TTS) after NAC on oncologic outcomes. They thus aimed to identify a cutoff for TTS after NAC and its effect on survival indices. METHODS: This was a retrospective review of all patients with HNSCC receiving NAC followed by surgery with curative intent between March 2016 and March 2019 at the MD Anderson Cancer Center. Receiver operating characteristic analysis was used to identify a cutoff for TTS, and this cutoff was used to analyze the overall survival (OS), locoregional recurrence rate, DM-free rate, and disease-free survival (DFS). A multivariate Cox regression analysis was performed. RESULTS: One hundred one patients were analyzed with a median follow-up of 24.7 months. The 3-year OS and locoregional recurrence rates did not differ with a TTS ≥ 34 days. However, the 3-year DM-free rate was significantly worse (56% vs 90%; P = .001) in the group with a TTS ≥ 34 days, and the 3-year DFS was significantly lower (26% vs 64%; P = .006). In a multivariate analysis, a TTS ≥ 34 days (hazard ratio [HR], 4.92; 95% confidence interval [CI], 1.84-13.13) and extracapsular extension (HR, 3.01; 95% CI, 1.13-8.00) were significant independent predictors of a poorer DM-free rate. Weight loss > 10% (HR, 5.53; 95% CI, 1.02-30.24) was the only independent predictor for a TTS ≥ 34 days. CONCLUSIONS: Emphasis should be placed on early definitive locoregional treatment after NAC, particularly in patients who do not respond to NAC. There is a need to validate these findings and establish new benchmarks for the interval between NAC and surgery.

BACKGROUND: Guidelines for follow-up after head and neck cancer (HNC) treatment recommend frequent clinical examinations and surveillance testing. Here, the authors describe real-world follow-up care for HNC survivors and variations in surveillance testing. METHODS: Using Surveillance, Epidemiology, and End Results (SEER)-Medicare data, this study examined a population-based cohort of HNC survivors between 2001 and 2011 Usage of cross-sectional head and neck imaging (CHNI), chest imaging (CI), positron emission tomography (PET), fiberoptic nasopharyngolaryngoscopy (FNPL), and, in irradiated patients, thyroid function testing (TFT) was captured over 2 consecutive surveillance years. Multivariate modeling with logistic regression analyses was used to assess variations by clinical factors, nonclinical factors, number and types of providers seen and their evolution over time. RESULTS: Among 13,836 HNC survivors, the majority saw a medical, radiation, or surgical oncologist and a primary care provider (PCP; 81.7%) in their first year of surveillance. However, only 58.1% underwent either PET or CHNI, 47.8% underwent CHNI, 64.1% underwent CI, 32.5% underwent PET scans, 55.0% underwent FNPL, and 55.9% underwent TFT. In multivariate analyses, patients who followed up with more providers and those who followed up with both a PCP and an oncologist were more likely to undergo surveillance testing (P < .007). However, adjusting for providers seen did not explain the variations in surveillance testing rates based on age, race, education, income level, and place of residence. Over time, there was a gradual increase in the use of PET scans and TFT during surveillance years. CONCLUSIONS: In this large SEER-Medicare data study, only half of HNC survivors received the recommended testing, and greater compliance was seen in those who followed up with both an oncologist and a PCP. More attention is needed to minimize variations in surveillance testing across sociodemographic groups.

BACKGROUND: Induction chemotherapy (IC) has been associated with a decreased risk of distant metastasis in locally advanced head and neck squamous cell carcinoma. However, its role in the treatment of oropharyngeal squamous cell carcinoma (OPSCC) is not well established. METHODS: The outcomes of patients with OPSCC treated with IC followed by concurrent chemoradiation (CRT) were compared with the outcomes of those treated with CRT alone. The primary outcome was overall survival (OS), and the secondary end points were the times to locoregional and distant recurrence. RESULTS: In an existing database, 585 patients met the inclusion criteria: 137 received IC plus CRT, and 448 received CRT. Most patients were positive for human papillomavirus (HPV; 90.9%). Patients receiving IC were more likely to present with a higher T stage, a higher N stage, and low neck disease. The 3-year OS rate was significantly lower in patients receiving IC (75.7%) versus CRT alone (92.9%). In a multicovariate analysis, receipt of IC (adjusted hazard ratio [aHR], 3.4; P < .001), HPV tumor status (aHR, 0.36; P = .002), and receipt of concurrent cetuximab (aHR, 2.7; P = .002) were independently associated with OS. The risk of distant metastasis was also significantly higher in IC patients (aHR, 2.8; P = .001), whereas an HPV-positive tumor status (aHR, 0.44; P = .032) and completion of therapy (aHR, 0.51; P = .034) were associated with a lower risk of distant metastasis. In HPV-positive patients, IC remained associated with distant metastatic progression (aHR, 2.6; P = .004) but not OS. CONCLUSIONS: In contrast to prior studies, IC was independently associated with worse OS and a higher risk of distant metastasis in patients with OPSCC. Future studies are needed to validate these findings.

BACKGROUND: Enhanced recovery after surgery (ERAS) pathways are well established in certain surgical specialties because findings have shown significant improvements in outcomes. Convincing literature in head and neck cancer (HNC) surgery is lacking. This study aimed to assess the effect of an ERAS pathway on National Surgical Quality Improvement Program (NSQIP)-based occurrences and pain-related outcomes in HNC surgery. METHODS: The study matched 200 patients undergoing head and neck oncologic surgery on an ERAS pathway between 1 March 2016 and 31 March 2019 with control subjects (1:1 ratio) during the same period. Demographic and perioperative data collected from the NSQIP database were extracted. Pain scores and medication usage were electronically extracted from our electronic medical record system and compared. Risk factors for high opioid usage also were assessed. RESULTS: Both groups were statistically similar in baseline characteristics. The ERAS group had fewer planned intensive care unit (ICU) admissions (4% vs. 14%; p < 0.001), a shorter mean hospital stay (7.2 ± 2.3 vs. 8.7 ± 4.2 days; p < 0.001), and fewer overall complications (18.6% vs. 27.0%; p = 0.045). Morphine milligram equivalent requirements over 72 h were significantly reduced during 72 h in the ERAS group (138.8 ± 181.5 vs. 207.9 ± 205.5; p < 0.001). In the multivariate analysis, the risk factors for high opioid analgesic usage included preoperative opioid usage, age younger than 65 years, race, patient-controlled analgesia use, and ICU admission. CONCLUSION: The study findings showed that ERAS in HNC surgery can result in improved outcomes and resource use, and that these results are sustainable. The outcomes described in this report can be further used to optimize ERAS pathways.

BACKGROUND: Neoadjuvant chemotherapy (NAC) has been used in patients with advanced head and neck cancers (HNCs) with the intent of downstaging tumors and suppressing distant metastases. However, to the authors' knowledge, the perioperative impact of NAC has not been systematically explored in patients with HNC. The objective of the current study was to compare perioperative outcomes with surgery upfront compared with patients treated with NAC. METHODS: Between March 1, 2016, and March 31, 2019, patients undergoing surgery for HNC with flap reconstruction at The University of Texas MD Anderson Cancer Center in Houston were included. Data were extracted from the prospectively maintained National Surgical Quality Improvement Program database. Postoperative complications, return to operating room, and readmission rates were compared. Univariate and multivariate analyses of length of stay and overall and wound complications were performed. RESULTS: A total of 834 patients were analyzed, 687 of whom (82.4%) underwent surgery upfront and 147 of whom (17.6%) received NAC. A total of 631 cases (75.7%) involved the upper aerodigestive tract whereas 203 cases (24.3%) were cutaneous. A total of 317 patients (38.0%) had recurrent disease. The NAC group was younger (P < .001) and had less hypertension (P = .011), but had more advanced clinical stage tumors (P < .001) and surgeries with multiple flap reconstruction (P = .007). Patient groups did not differ with regard to wound complications (P = .47), return to operating room (P = .31), or readmission rates (P = .49). The NAC group received more blood transfusions (P < .001) but was found to have a lower risk of overall complications on multivariate analysis (odds ratio, 0.50; 95% CI, 0.30-0.83). The overall complication rate was unchanged with surgery performed ≤21 days after the last chemotherapy cycle. CONCLUSIONS: Patients undergoing NAC appear to have a higher disease burden but tend to be younger and healthier. Within the context of this inherent selection bias, NAC does not appear to increase perioperative morbidity among patients undergoing surgery for HNC.

PURPOSE OF REVIEW: Surgical management of locally advanced oral cavity squamous cell carcinomas (OCSCC) has long been recognized as a primary treatment modality. Technological advances have led to significant improvements in our surgical approach, from improvement in the visualization of tumors to more efficient and precise reconstruction. Here, we review the latest technological advances in surgical extirpation and reconstruction of locally advanced OCSCCs. RECENT FINDINGS: The focus of technological innovation in surgical extirpation has been on improving visualization, with the use of intraoperative ultrasound for margin delineation, intraoperative navigation, narrow-band imaging, and the use of fluorescence. Though early, these are promising steps to ensuring complete resection of the cancer. Advances in reconstruction have been centered on the incorporation of computer assisted design, manufacturing, and virtual surgical planning, allowing for more complex three-dimensional defects to be expeditiously reconstructed. As these technologies are still under development, their impact on oncologic outcomes are not yet robustly defined; however, as technology continues to advance and become more widely available, new technologies will undoubtedly become integrated into enhancing surgical precision and planning.

IMPORTANCE: A gap in knowledge exists concerning the functional outcomes and complications when comparing various surgical approaches for retropharyngeal lymph node (RPLN) metastases. OBJECTIVE: To explore perioperative outcomes, functional outcomes, and complications associated in the treatment of RPLN metastases. DESIGN: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) protocol was used to conduct a scoping review of the PubMed and Scopus databases. REVIEW METHODS: We systematically searched 2 databases from inception to January 2023 for articles examining the treatment approaches and postoperative outcomes in the retropharyngeal space. We included English records about surgical approaches, complications, functional outcomes for patients >18 years old with retropharyngeal lymphadenopathy. RESULTS: One-hundred ninety-nine articles were identified, of which 17 were included in the analysis. Three studies assessed RPLN dissection in the postradiation setting. We identified limited knowledge about functional outcomes and complications following surgery for retropharyngeal lymphadenopathy. Overall, acute postoperative dysphagia was documented in 35/170 patients (20.5%). However, the assessment of dysphagia was limited, and not described in the majority of studies. The overall rate of postoperative neuropathy and hematoma were 4.1% and 4.7%, respectively. No postoperative hematomas were documented in the transcervical approach. CONCLUSION: Our findings underscore the need for further research on postoperative outcomes following RPLN dissection. We recommend further studies focusing on objective swallow assessments and long-term outcomes of either surgical approaches.

BACKGROUND: The impact of timing of PORT initiation for major salivary gland cancers on survival is unknown. We aim to examine the impact of PORT timeliness on overall survival (OS) of patients with major salivary gland cancers. METHODS: This was a cross-sectional analysis using data from the National Cancer Database (2004-2017) and included patients with major salivary gland cancer treated with surgery and PORT. RESULTS: In total, 5701 patients were included (3133 [55%] male, 4644 [82%] white, mean age 59 ± 16 years). For the overall cohort, PORT >6 weeks was not associated with decreased OS (1.00 aHR, 95% CI 0.89-1.11). When specifically examining patients with mucoepidermoid carcinoma, PORT >6 weeks was associated with a decreased OS (1.27 aHR, 95% CI 1.01-1.58). CONCLUSIONS: Overall, this analysis did not demonstrate a survival benefit for initiating PORT within 6 weeks for patients with salivary gland malignancies. Subset analysis did support initiating PORT within 6 weeks after resection for patients with mucoepidermoid carcinomas. This was not demonstrated in other major salivary gland cancer histologies.
RESUMEN
OBJECTIVE(S): The purpose of this study was to compare computer-assisted mandibular plating to conventional plating using quantitative metrics. METHODS: Patients scheduled to undergo mandibular reconstruction were randomized to three-dimensional modelling for preoperative plate bending or intraoperative freehand bending. Preoperative and postoperative head and neck computed tomography scans were obtained to generate computer models of the reconstruction. The overall plate surface contact area, mean plate-to-bone distance, degree of conformance, and position of the condylar head within the glenoid fossa between pre- and post-operative scans were calculated. RESULTS: Twenty patients were included with a mean age of 57.8 years (standard deviation [SD] = 13.6). The mean follow-up time was 9.8 months (range = 1.6-22.3). Reconstruction was performed with fibular (25%) or scapular free flaps (75%). The percentage of surface contact between the reconstructive plate and mandible was improved with three-dimensional models compared to freehand bending (93.9 ± 7.7% vs. 78.0 ± 19.9%, p = 0.04). There was improved overall plate-to-bone distance (3D model: 0.7 ± 0.31 mm vs. conventional: 1.3 ± 0.8 mm, p = 0.06). Total intraoperative time was non-significantly decreased with the use of a model (3D model: 726.5 ± 89.1 min vs. conventional: 757.3 ± 84.1 min, p = 0.44). There were no differences in condylar head position or postoperative complications. CONCLUSION: Computer-assisted mandibular plating can be used to improve the accuracy of plate contouring.

OBJECTIVE: Stage 3 patients with clinically positive nodal metastasis are treated with therapeutic neck dissection and adjuvant systemic therapy. The aim of our study was to examined the predictability of pre-operative CT as a nodal drainage assessment tool. METHODS: Retrospective review of all patients with clinically positive head and neck cutaneous melanoma between 2010 and 2019. Clinical disease was diagnosed as radiological suspicious, biopsy-proven node. A pre-operative CT evaluation for nodal metastasis was compared to pathology report. RESULTS: A total of 53 patients were included. Forty patients (75.5%) were males with a mean age of 59 (SD 15.52). The majority of patients (26.4%) had an unknown primary site. The most common sites for primary were the cheek in eight patients (15.1%) followed by forehead (9.4%) and lateral neck (9.4%). Preoperative CT predicted nodal disease in 84.6% of cases. The primary region that mainly failed from the previously described clinical prediction was the upper anterior neck with 83.3% parotid involvement. A total of 10 patients (18.9%) were diagnosis with non-clinical nodes on pathology with a median non-clinical node of 1 (range 1-2). Of them, 9 (90%) were in the same clinical levels detected by CT. Pre-operative CT was associated with a neck level accuracy of 98.1%. CONCLUSION: Stage 3 head and neck melanoma with clinically positive nodal metastasis that are eligible for an adjuvant systemic treatment, may benefit from a highly selective neck dissection according to their pre-operative imaging studies. This should be further evaluated in a large-scale clinical trial. LEVEL OF EVIDENCE: 3 Laryngoscope, 2024.
RESUMEN
PURPOSE: Randomized controlled trials have demonstrated that palliative care (PC) can improve quality of life and survival for outpatients with advanced cancer, but there are limited population-based data on the value of inpatient PC. We assessed PC as a component of high-value care among a nationally representative sample of inpatients with metastatic cancer and identified hospitalization characteristics significantly associated with high costs. METHODS: Hospitalizations of patients 18 years and older with a primary diagnosis of metastatic cancer from the National Inpatient Sample from 2010 to 2019 were analyzed. We used multivariable mixed-effects logistic regression to assess medical services, patient demographics, and hospital characteristics associated with higher charges billed to insurance and hospital costs. Generalized linear mixed-effects models were used to determine cost savings associated with provision of PC. RESULTS: Among 397,691 hospitalizations from 2010 to 2019, the median charge per admission increased by 24.9%, from $44,904 in US dollars (USD) to $56,098 USD, whereas the median hospital cost remained stable at $14,300 USD. Receipt of inpatient PC was associated with significantly lower charges (odds ratio [OR], 0.62 [95% CI, 0.61 to 0.64]; P < .001) and costs (OR, 0.59 [95% CI, 0.58 to 0.61]; P < .001). Factors associated with high charges were receipt of invasive medical ventilation (P < .001) or systemic therapy (P < .001), Hispanic patients (P < .001), young age (18-49 years, P < .001), and for-profit hospitals (P < .001). PC provision was associated with a $1,310 USD (-13.6%, P < .001) reduction in costs per hospitalization compared with no PC, independent of the receipt of invasive care and age. CONCLUSION: Inpatient PC is associated with reduced hospital costs for patients with metastatic cancer, irrespective of age and receipt of aggressive interventions. Integration of inpatient PC may de-escalate costs incurred through low-value inpatient interventions.
RESUMEN
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: 3 Laryngoscope, 134:3664-3672, 2024.

PURPOSE: Osteoradionecrosis of the jaw (ORN) can manifest in varying severity. The aim of this study is to identify ORN risk factors and develop a novel classification to depict the severity of ORN. METHODS: Consecutive patients with head and neck cancer (HNC) treated with curative-intent intensity-modulated radiation therapy (IMRT) (≥45 Gy) from 2011 to 2017 were included. Occurrence of ORN was identified from in-house prospective dental and clinical databases and charts. Multivariable logistic regression model was used to identify risk factors and stratify patients into high-risk and low-risk groups. A novel ORN classification system was developed to depict ORN severity by modifying existing systems and incorporating expert opinion. The performance of the novel system was compared with 15 existing systems for their ability to identify and predict serious ORN event (jaw fracture or requiring jaw resection). RESULTS: ORN was identified in 219 of 2,732 (8%) consecutive patients with HNC. Factors associated with high risk of ORN were oral cavity or oropharyngeal primaries, received IMRT dose ≥60 Gy, current/ex-smokers, and/or stage III to IV periodontal condition. The ORN rate for high-risk versus low-risk patients was 12.7% versus 3.1% (P < .001) with an AUC of 0.71. Existing ORN systems overclassified serious ORN events and failed to recognize maxillary ORN. A novel ORN classification system, ClinRad, was proposed on the basis of vertical extent of bone necrosis and presence/absence of exposed bone/fistula. This system detected serious ORN events in 5.7% of patients and statistically outperformed existing systems. CONCLUSION: We identified risk factors for ORN and proposed a novel ORN classification system on the basis of vertical extent of bone necrosis and presence/absence of exposed bone/fistula. It outperformed existing systems in depicting the seriousness of ORN and may facilitate clinical care and clinical trials.

BACKGROUND: To address the rehabilitative barriers to frequency and precision of care, we conducted a pilot study of a biofeedback electropalatography (EPG) device paired with telemedicine for patients who underwent primary surgery +/- adjuvant radiation for oral cavity carcinoma. We hypothesized that lingual optimization followed by telemedicine-enabled biofeedback electropalatography rehabilitation (TEBER) would further improve speech and swallowing outcomes after "standard-of-care" SOC rehabilitation. METHOD: Pilot prospective 8-week (TEBER) program following 8 weeks of (SOC) rehabilitation. RESULTS: Twenty-seven patients were included and 11 completed the protocol. When examining the benefit of TEBER independent of standard of care, "range-of-liquids" improved by +0.36 [95% CI, 0.02-0.70, p = 0.05] and "range-of-solids" improved by +0.73 [95% CI, 0.12-1.34, p = 0.03]. There was a positive trend toward better oral cavity obliteration; residual volume decreased by -1.2 [95% CI, -2.45 to 0.053, p = 0.06], and "nutritional-mode" increased by +0.55 [95% CI, -0.15 to 1.24, p = 0.08]. CONCLUSION: This pilot suggests that TEBER bolsters oral rehabilitation after 8 weeks of SOC lingual range of motion.

The use of robotics in head and neck surgery has drastically increased over the past two decades. Transoral robotic surgery has revolutionized the surgical approach to the upper aerodigestive tract including the oropharynx and supraglottic larynx. The expanded use and improving technology of robotics have allowed for new approaches in both the ablative and reconstructive aspects of head and neck surgery. Here, we discuss the recent updates in robotics in head and neck surgery and future directions the field may turn.
RESUMEN
BACKGROUND: As patient survival with head and neck cancer has improved, treatment goals have had to evolve to focus on improving quality of life. Traditionally, patients who have undergone mandibulectomy are left with an insensate chin and lower lip secondary to resection of the inferior alveolar nerve (IAN). The purpose of this study was to critically evaluate the authors' initial experience using processed nerve allografts (PNA) for IAN reconstruction following oncologic mandibulectomy and reconstruction with free fibula osteocutaneous flaps and to assess their patients' sensory outcomes. METHODS: The authors performed a retrospective review of the first 32 patients who underwent immediate IAN reconstruction with PNA at the time of oncologic mandibulectomy and mandible reconstruction with free fibula osteocutaneous flaps at The University of Texas M. D. Anderson Cancer Center over a 1-year period. Semmes-Weinstein filament sensory testing was conducted at multiple surgical follow-up appointments to evaluate the quality of sensory recovery. RESULTS: Thirteen of the 32 patients underwent postoperative Semmes-Weinstein filament testing. All 13 patients demonstrated partial return of sensation. At a mean follow-up of 8.33 months, the average level of sensation was 60.93% that of the unaffected side of the lower lip. CONCLUSIONS: Patients were consistently afforded improvement in lower lip sensation using PNA-based IAN grafting as an adjunct to free fibula-based mandible reconstruction. The procedure adds no additional surgical morbidity and has shown consistent positive results.

Importance: While several studies have documented a link between socioeconomic status and survival in head and neck cancer, nearly all have used ecologic, community-based measures. Studies using more granular patient-level data are lacking. Objective: To determine the association of baseline annual household income with financial toxicity, health utility, and survival. Design, Setting, and Participants: This was a prospective cohort of adult patients with head and neck cancer treated at a tertiary cancer center in Toronto, Ontario, between September 17, 2015, and December 19, 2019. Data analysis was performed from April to December 2021. Exposures: Annual household income at time of diagnosis. Main Outcome and Measures: The primary outcome of interest was disease-free survival. Secondary outcomes included subjective financial toxicity, measured using the Financial Index of Toxicity (FIT) tool, and health utility, measured using the Health Utilities Index Mark 3. Cox proportional hazards models were used to estimate the association between household income and survival. Income was regressed onto log-transformed FIT scores using linear models. The association between income and health utility was explored using generalized linear models. Generalized estimating equations were used to account for patient-level clustering. Results: There were 555 patients (mean [SD] age, 62.7 [10.7] years; 109 [20%] women and 446 [80%] men) included in this cohort. Two-year disease-free survival was worse for patients in the bottom income quartile (<$30â¯000: 67%; 95% CI, 58%-78%) compared with the top quartile (≥$90â¯000: 88%; 95% CI, 83%-93%). In risk-adjusted models, patients in the bottom income quartile had inferior disease-free survival (adjusted hazard ratio, 2.13; 95% CI, 1.22-3.71) and overall survival (adjusted hazard ratio, 2.01; 95% CI, 0.94-4.29), when compared with patients in the highest quartile. The average FIT score was 22.6 in the lowest income quartile vs 11.7 in the highest quartile. In adjusted analysis, low-income patients had 12-month FIT scores that were, on average, 134% higher (worse) (95% CI, 16%-253%) than high-income patients. Similarly, health utility scores were, on average, 0.104 points lower (95% CI, 0.026-0.182) for low-income patients in adjusted analysis. Conclusions and Relevance: In this cohort study, patients with head and neck cancer with a household income less than CAD$30â¯000 experienced worse financial toxicity, health status, and disease-free survival. Significant disparities exist for Ontario's patients with head and neck cancer.

OBJECTIVE: The aim of the study is to describe the factors that influence outcome in adults with head and neck osteosarcoma (HNO) with a specific focus on the margin status. METHODS: Patients with a diagnosis of HNO between the years 1996-2021 were reviewed from the Canadian Sarcoma Research and Clinical Collaboration (CanSaRCC) Database. Baseline characteristics, pathology, treatment, and outcomes were analyzed. Univariable (UVA) and multivariable (MVA) Cox regression models were performed. 5-year locoregional control rate and overall survival (OS) were estimated using Kaplan-Meier method and Log-Rank test. RESULTS: Of 50 patients with a median age of 40 years (range 16-80), 27 (54%) were male. HNO commonly involved the mandible (n = 21, 42%) followed by maxilla (n = 15, 30%). Thirteen (33.3%) had low-intermediate grade and 26 (66.6%) had high grade tumors. Three patients (6%) had negative resection margins (>5 mm), 24 (48%) had close margins (1-5 mm), 15 (30%) had positive margins (<1mm) and 7 (16%) had unknown margin status. In total, 39 (78%) received chemotherapy - 22 (44%) received neoadjuvant chemotherapy while 17 (34%) received adjuvant chemotherapy. A total of 12 (24%) patients received radiotherapy, of whom 8 (16%) had adjuvant and 3 (6%) had neo-adjuvant. Median follow-up time was 6.3 years (range 0.26-24.9). Disease recurred in 21 patients (42%), of whom 15 (30%) had local recurrence only, 4 (8%) had distant metastasis, and 2 (4%) had both local and distant recurrence. 5-year locoregional control rate and OS was 62% and 79.2% respectively. Resection margins <3 mm was associated with lower 5 years OS and locoregional control rate (Log-Rank p = 0.02, p = 0.01 respectively). CONCLUSION: Osteosarcomas of the head and neck are rare and local recurrence remains a concern. Surgical resection with negative resection margins may improve survival, and a 3 mm resection margin threshold may optimize survival. Radiotherapy and/or chemotherapy should be considered in a multidisciplinary setting based on risk-features.

BACKGROUND: We aimed to develop and validate a risk-scoring system for distant metastases (DMs) in oral cavity carcinoma (OCC). METHODS: Patients with OCC who were treated at 4 tertiary cancer institutions with curative surgery with or without postoperative radiation/chemoradiation therapy were randomly assigned to discovery or validation cohorts (3:2 ratio). Cases were staged on the basis of tumor, node, and metastasis staging according to the eighth edition of the American Joint Committee on Cancer/Union for International Cancer Control guidelines. Predictors of DMs on multivariable analysis in the discovery cohort were used to develop a risk-score model and classify patients into risk groups. The utility of the risk classification was evaluated in the validation cohort. RESULTS: Overall, 2749 patients were analyzed. Predictors (risk score coefficient) of DMs in the discovery cohort were the following: pathological stage (p)T3-4 (0.4), pN+ (N1: 0.8; N2: 1.0; N3: 1.5), histologic grade (G) 3 (G3, 0.7), and lymphovascular invasion (0.4). The DM risk groups were defined by the sum of the following risk score coefficients: high (>1.7), intermediate (0.7-1.7), and standard risk (<0.7). The 5-year DM rates (high/intermediate/standard risk groups) were 30%/15%/4% in the discovery cohort (C-index = 0.79) and 35%/16%/5% in the validation cohort, respectively (C-index = 0.77; both P < .001). In the whole cohort, this predictive model showed excellent discriminative ability in predicting DMs without locoregional failure (29%/11%/1%), later (>2 year) DMs (11%/4%/2%), and DMs in patients treated with surgery (20%/12%/5%), postoperative radiation therapy (34%/17%/4%), and postoperative chemoradiation therapy (39%/18%/7%) (all P < .001). The 5-year overall survival rates in the overall cohort were 25%/51%/67% (P < .001). CONCLUSIONS: Patients at higher risk for DMs were identified by use of a predictive-score model for DMs that included pT3-4, pN1/2/3, G3, and lymphovascular invasion. Identified patients may be evaluated for individualized risk-adaptive treatment escalation and/or surveillance strategies.

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.
