RESUMO
OBJECTIVE: To evaluate national trends in racial disparities for patients undergoing head and neck reconstructive surgery. METHODS: Retrospective analysis using the 2008 to 2021 American College of Surgeons National Surgical Quality Improvement Program database. Patients receiving microvascular free tissue transfer were eligible for inclusion. Pediatric patients and those treated by non-otolaryngologists were excluded. Outcomes were analyzed with univariate and multivariable models. RESULTS: A total of 5831 head and neck free flap cases were analyzed, 4869 (83.5%) were White, 560 (9.6%) were Black or African American, and 402 (6.9%) were Asian, Native American, or other groups (ANAOG). The proportion of Black or African American patients and ANAOG patients undergoing free tissue transfer increased significantly over the time period (p = 0.047 and p = 0.010, respectively). However, there was a downtrend that started around 2017. In a multivariable model, Black or African American race was not associated with readmission (OR = 0.99 [95% CI 0.74, 1.31], p > 0.05), returning to the operating room (OR = 1.20 [95% CI 0.96, 1.49], p > 0.05), or any post-operative complication (OR = 0.83 [95% CI 0.68, 1.01], p > 0.05). There were also no significant associations found in the ANAOG population on multivariate analysis (p > 0.05 for all). CONCLUSION: The percentage of free tissue transfer performed in patients from minority backgrounds with head and neck cancer has been increasing in the United States. Outcomes after head and neck microvascular reconstruction are similar when stratified by race. However, racial disparities remain and further work is necessary to reduce these disparities.

RESUMO
BACKGROUND: Advancements in immunotherapy for recurrent head and neck cancer have necessitated a better understanding of salvage surgical outcomes. This study aimed to determine patterns of failure following salvage head and neck surgery. METHODS: A retrospective cohort study was conducted of 280 patients who underwent salvage surgery for recurrent mucosal squamous cell carcinoma from 1997 to 2018. Cumulative incidence was calculated using the nonparametric Aalen-Johansen estimator. Time to recurrence (TTR) and overall survival (OS) were estimated using the Kaplan-Meier method and multivariable Cox proportional hazard models were used to evaluate associated factors. RESULTS: The 2 and 5-year cumulative incidence rates of second recurrence were 48.3 % (95 % CI 42.4-54.3) and 54.9 % (95 % CI 48.9-60.8), respectively. At 5 years, second locoregional recurrence was twice as common as distant recurrence (41.5 % [95 % CI 35.6-47.4] vs. 21.7 % [95 % CI 16.8-26.6]). The median TTR was 21.1 months (95 % CI 4.4-34.8), which varied by site (38.2 larynx/hypopharynx, 13.9 oral cavity, 8.3 sinonasal, and 7.8 oropharynx, P=.0001). The median OS was 32.1 months (95 % CI 24.1-47.6) and was worse for patients who were Black (hazard ratio [HR] 2.15, 95 % CI 1.19-3.9), current smokers (HR 2.73, 95 % CI 1.53-4.88), former smokers (HR 2.00, 95 % CI 1.19-3.35), ≥ 60 years of age (HR 1.41, 95 % CI 1.01-1.97), or received multimodal primary therapy (HR 1.98, 95 % CI 1.26-3.13). CONCLUSION: Rates of recurrence and mortality after salvage surgery were poor but worse for patients who were Black, older, smoked, had initial multimodal therapy, or had sinonasal or oropharyngeal cancers.

PURPOSE OF REVIEW: Surgery, radiation, and chemotherapy are often utilized in the treatment of head and neck cancer. These treatments can cause extensive scarring within the neck and can limit the viability of recipient vessels for further microvascular reconstruction. Patients with vessel-depleted necks provide a significant challenge for microvascular surgeons and are a topic of much discussion in the field. RECENT FINDINGS: While reconstruction in the vessel-depleted neck is an active area of interest, the patient population is rare. Therefore, single institution series with small numbers comprise the majority of published literature. Recent publications describe techniques for identifying adequate recipient vessel options outside of the field of treatment with excellent free flap outcomes. Further, recent summary articles describe techniques for addressing issues with pedicle length that can arise when using vessels that are far from the defect to be reconstructed. SUMMARY: When viable vessel options are available within the treatment field, these recipient vessels can be used with good reliability and free flap success. If in-field recipient vessels are not available, minimal access incisions can be used to identify superficial temporal, angular, contralateral facial, or transverse cervical vessels. Further away from the treatment field, internal mammary vessels can be harvested through open or robotic approaches. If the use of these distant vessels creates issues with pedicle length, interposition vein grafts, arteriovenous (AV) loops, or flow-through flaps can be used to augment vessel length.

BACKGROUND: Evaluate whether extranodal extension (ENE) extent impacts outcomes in patients with oral cavity squamous cell carcinoma (OCSCC). METHODS: From an institutional database, patients with OCSCC and pathologic ENE who received adjuvant treatment were included. Surgical slides were reviewed to confirm ENE extent. Multivariable Cox regression was used to relate patient/treatment characteristics with disease-free survival (DFS) and overall survival (OS). ENE was analyzed as both a dichotomous and continuous variable. RESULTS: A total of 113 patients were identified. Between major (>2 mm) versus minor ENE (≤2 mm), there was no significant difference in DFS (HR 1.18, 95%CI 0.72-1.92, p = 0.51) or OS (HR 1.17, 95%CI 0.70-1.96, p = 0.55). There was no significant association between ENE as a continuous variable and DFS (HR 0.97 per mm, 95%CI 0.87-1.4, p = 0.96) or OS (HR 0.96 per mm, 95%CI 0.83-1.11, p = 0.58). CONCLUSION: No significant relationship was seen between ENE extent and DFS or OS in individuals with OCSCC.

BACKGROUND: Primary fit tracheoesophageal puncture (TEP) is widely preferred for individuals who have not undergone prior radiation. However, there is no consensus on the relative utility of primary-fit TEP in the setting of salvage laryngectomy. METHODS: A retrospective, single-center review was conducted of individuals undergoing laryngectomy with primary fit TEP between 2012 and 2018. Multivariable analysis was conducted to compare short-term and long-term complications, as well as speech and swallowing outcomes, of those who underwent primary versus salvage laryngectomy. RESULTS: In this study, 134 patients underwent total laryngectomy with primary fit TEP. Aside from a higher rate of peristomal dehiscence (13.1% vs. 1.4%) found in the salvage group, there was no difference in incidence of all other complications, including pharyngocutaneous fistula formation. The groups had comparable speech and swallow outcomes. CONCLUSION: Primary fit TEP is a safe and effective surgical choice for individuals undergoing salvage laryngectomy who desire a voice prosthesis.
RESUMO
OBJECTIVE: In light of the recent US Food and Drug Administration (FDA) Class 2 safety recall notice for anastomotic coupling devices, it is important to understand related adverse events. The aim of this study was to characterize adverse events in anastomotic coupling devices for microvascular reconstruction. METHODS: A retrospective cross-sectional analysis using the 2011 to 2021 US FDA Manufacturer and User Facility Device Experience (MAUDE) database. All reports of adverse events involving anastomotic coupling devices were retrieved from the MAUDE database. Descriptive statistics were used to analyze categorized events. RESULTS: There were a total of 293 documented adverse events related to anastomotic coupling devices. These adverse events resulted in 91 (31.1 %) patient injuries and 239 (81.6 %) device malfunctions. The most frequent patient problems were thrombosis/hematoma (n = 38; 41.8 %), unspecified injury (n = 31; 34.1 %), and failure to anastomose (n = 13; 14.3 %). Free flap necrosis was reported in 42 % of thrombosis/hematoma cases (n = 16). The most common malfunctions were devices operating differently than expected (n = 74; 31.0 %), connection problems (n = 41; 17.2 %), and twisted/bent material (n = 19; 7.9 %). There was no significant trend in the number of adverse events over the study period (p > 0.05). CONCLUSIONS: Adverse events from anastomotic coupling devices represent an important and modifiable factor in free tissue failure. Adverse events are predominately related to devices operating differently than expected and may result in vascular compromise of the free flap. Reconstructive surgeons should be cognizant of defective anastomotic coupling devices and be prepared to utilize traditional hand-sewn anastomosis.

OBJECTIVES: To describe our technique, review indications, and evaluate the outcomes of the minimal access approach for recipient vessel identification in microvascular tissue transfer. METHODS: Retrospective chart review of all patients who underwent microvascular reconstruction using the minimal access technique between 2015 and 2021. RESULTS: We report 236 cases, comprising 214 patients with a mean age of 60.2 years (3-88). The most common primary defect sites were the mandible (22.6%), cranium (14%), maxilla (13.2%), skull base (12.8%), and nose/nasal cavity (10.6%). Indications for free flap reconstruction included head and neck cancer extirpation (32.2%), osteoradionecrosis (29.7%), acquired deformity (14.0%), chronic wound (11.9%) and oral motor dysfunction (7.2%). Free flap donor sites used were the anterolateral thigh (84.3%), fibula (7.2%), and radial forearm (6.4%). Vessels utilized include superficial temporal (49.8%), facial (38.3%), angular (11.1%), and transverse cervical (0.4%). The overall complication rate was 14% (n = 33), with surgical complications at the recipient site accounting for 67.6% (n = 25). Flap failure occurred in 3.4% of procedures. Prior head and neck surgery and free flaps were associated with an increased risk of major recipient site complications (n = 20, p = 0.0257 and n = 14, p = 0.0117, respectively). CONCLUSION: Minimal access techniques allow consistent recipient vessel identification for microvascular-free tissue transfer. These approaches may be utilized in reconstructing a broad range of head and neck defects, are low morbidity, and contribute to an overall shorter length of stay.

OBJECTIVE: To report the microorganisms and their antibiotic sensitivity profile from tissue cultures and stains at the time of anterolateral thigh fascia lata (ALTFL) rescue flap for management of mandibular osteoradionecrosis (ORN). METHODS: Retrospective chart review of patients who underwent ALTFL rescue flap for native mandibular ORN between 2011 and 2022. RESULTS: Twenty-six cases comprising 24 patients (mean age 65.4 years, 65.4% male) with mandibular ORN from whom tissue cultures and gram stain were obtained at the time of ALTFL rescue flap. 57.7% grew bacterial species, while 34.6% grew fungal species. Multibacterial speciation was noted in 26.9% of cultures. A combination of bacterial and fungal growth was also seen in 15.4% of cases. All gram-positive cocci (GPC) were pansensitive to antibiotics except for one case of Staphylococcus aureus, which was resistant to levofloxacin. Gram-negative bacilli (GNB) species were isolated in 50.0% of cases. All fungal growth was due to Candida species. No growth was noted in 23.1% of cases. Multidrug resistance was noted in 53.8% of cases when GNB was isolated. CONCLUSION: We report 76.9% of our cases of mandibular ORN had microbial growth from tissue cultures obtained at the time of the ALTFL rescue flap. Fungal growth was noted in a substantial number of cases and should be obtained as a specimen when pursuing culture-driven antibiotic therapy. Most GPCs were pansensitive to antibiotics, while GNBs were often the harbinger of multidrug resistant mandibular ORN. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:166-169, 2024.

Importance: Positive margins and margin clearance are risk factors for recurrence in oral cavity squamous cell carcinoma (OCSCC), and these features are used to guide decisions regarding adjuvant radiation treatment. However, the prognostic value of intraoperative tumor bed vs resection specimen sampling is not well defined. Objective: To determine the prognostic implications of intraoperative margin assessment methods (tumor bed vs resection specimen sampling) with recurrence among patients who undergo surgical resection for OCSCC. Design, Setting, and Participants: This was a retrospective study of patients who had undergone surgical resection of OCSCC between January 1, 2000, and December 31, 2021, at a tertiary-level academic institution. Patients were grouped by margin assessment method (tumor bed [defect] or resection specimen sampling). Of 223 patients with OCSCC, 109 patients had localized tumors (pT1-T2, cN0), 154 had advanced tumors, and 40 were included in both cohorts. Disease recurrence after surgery was estimated by the cumulative incidence method and compared between cohorts using hazard ratios (HRs). Data analyses were performed from January 5, 2023, to April 30, 2023. Main Outcome and Measures: Recurrence-free survival (RFS). Results: The study population comprised 223 patients (mean [SD] age, 62.7 [12.0] years; 88 (39.5%) female and 200 [90.0%] White individuals) of whom 158 (70.9%) had defect-driven and 65 (29.1%) had specimen-driven margin sampling. Among the 109 patients with localized cancer, intraoperative positive margins were found in 5 of 67 (7.5%) vs 8 of 42 (19.0%) for defect- vs specimen-driven sampling, respectively. Final positive margins were 3.0% for defect- (2 of 67) and 2.4% for specimen-driven (1 of 42) margin assessment. Among the 154 patients with advanced cancer, intraoperative positive margins were found in 29 of 114 (25.4%) vs 13 of 40 (32.5%) for defect- and specimen-driven margins, respectively. Final positive margins were higher in the defect-driven group (9 of 114 [7.9%] vs 1 of 40 [2.5%]). When stratified by margin assessment method, the 3-year rates of local recurrence (9.7% vs 5.1%; HR, 1.37; 95% CI, 0.51-3.66), regional recurrence (11.0% vs 10.4%; HR, 0.85; 95% CI, 0.37-1.94), and distant recurrence (6.4% vs 5.0%; HR, 1.10; 95% CI, 0.36-3.35) were not different for defect- vs specimen-driven sampling cohorts, respectively. The 3-year rate of any recurrence was 18.9% in the defect- and 15.2% in the specimen-driven cohort (HR, 0.93; 95% CI, 0.48-1.81). There were no differences in cumulative incidence of disease recurrence when comparing defect- vs specimen-driven cases. Conclusions and Relevance: The findings of this retrospective cohort study indicate that margin assessment methods using either defect- or specimen-driven sampling did not demonstrate a clear association with the risk of recurrence after OCSCC resection. Specimen-driven sampling may be associated with reduced surgical margin positivity rates, which often necessitate concurrent chemotherapy with adjuvant radiation therapy.

OBJECTIVE: Small molecule inhibitors (SMIs) are targeted therapies increasingly used in advanced thyroid carcinomas. This study aimed to evaluate the survival outcomes of thyroid cancer on SMI treatment, including in patients with brain metastases. METHODS: This retrospective study included patients with thyroid carcinomas who received at least one SMI between 2008 and 2022 at a tertiary level, academic institution. SMI included lenvatinib, sorafenib, dabrafenib-trametinib, selpercatinib, and cabozantinib. Patients were grouped by the presence of brain metastasis. Kaplan-Meier and log-rank tests modeled the overall survival (OS), defined from detection of first metastasis. RESULTS: In total, 116 patients (49.1% female, median age 61.1 years [IQR, 51.1-71.0]) were included. Thyroid cancer subtypes were: 57 (49.6%) papillary, 23 (19.8%) anaplastic, 23 (19.8%) medullary, and 13 (11.2%) follicular. There were 18 (15.5%) patients with brain metastases, and 98 (84.5%) with visceral metastases. Age, sex, thyroid subtype, SMI, and time to recurrence were not different between cohorts. OS was shorter in the brain metastasis cohort (31.7 vs 42.2 months, P =.44) and was not different after excluding anaplastic thyroid cancer (29.1 vs 62.3 months, P =.21). In the case of papillary thyroid cancer, patients with brain metastases trended toward worse OS (22.0 vs 59.9 months, P =.13). Nonanaplastic histology, total thyroidectomy (OR, 40.0; P <.001), number of unique therapies (OR, 10.9; P =.047), and mutation-directed therapy (OR, 24.7; P =.003) were associated with improved OS. CONCLUSION: This single-institutional analysis reports survival outcomes of 116 patients with advanced thyroid cancer on targeted therapies, including 18 patients with brain metastases. Mutation-directed therapy for BRAFV600E mutations, RET mutations, RET fusions, and NTRK fusions had superior survival.

BACKGROUND: Metastatic or locally advanced cutaneous squamous cell carcinoma (cSCC) can be treated with immunotherapy (IO). Cranial nerve involvement (CNI) is uncommon in cSCC and is a poor prognostic factor. Our aim is to describe how patients with CNI respond to IO monotherapy and/or as an adjunct to RT. METHODS: Under an IRB approved protocol, patients with histologically proven cSCC of the head and neck with CNI treated with IO were retrospectively reviewed. RESULTS: Twelve patients were included and received cemiplimab or pembrolizumab. Eight patients had CNI at diagnosis, and 4 at time of recurrence after non-IO therapy. Best responses were complete response (1), partial response (7), stable disease (1), progressive disease (2), and pending response (1). Nine patients are alive, 6 of which remain on IO. CONCLUSIONS: In this cohort, IO showed clinical response in 83% of patients, indicating IO can be an effective monotherapy, reserving RT for instances of local failure after IO.

Importance: Mandibular osteoradionecrosis (ORN) is a progressive disease that can be difficult to treat. Conservative measures often fail, while conventional definitive management requires a morbid segmental resection with osteocutaneous reconstruction. Evidence of the anterolateral thigh fascia lata (ALTFL) rescue flap technique's safety, effectiveness, and long-term outcomes is needed. Objective: To determine the long-term outcomes of the ALTFL rescue flap procedure for treating patients with mandibular ORN. Design, Settings, and Participants: This was a retrospective medical record review performed at a single tertiary-level academic health care institution with patients who were appropriate candidates for the ALTFL procedure to treat mandibular ORN from March 3, 2011, to December 31, 2022. Data analyses were performed from January 1 to March 26, 2023. Main Outcomes and Measures: Patient characteristics, preoperative radiographic Notani staging, intraoperative defect size, length of stay, complication rates, and clinical and radiographic findings of progression-free intervals. Results: The study population of 43 patients (mean [SD] age, 66.1 [47-80] years; 24 [55.8%] male individuals) included 52 cases of mandibular ORN. The preoperative Notani staging of the study population was known for 46 of the 52 total cases: 11 cases (23.9%) were stage I; 21 (45.7%), stage II; and 14 (30.4%), stage III. The mean defect area was 20.9 cm2. Successful arrest of ORN disease progression was noted in the clinical and radiographic findings of 50 of the 52 (96.2%) cases, with only 2 (3.8%) cases subsequently requiring fibular free flap reconstruction. The major complication rate was 1.9% (1 case). Clinical and radiographic progression-free intervals were assessed, and no statistically significant differences were noted between Notani staging groups (log-rank P = .43 and P = .43, respectively); ie, patients with stage III disease had no significant difference in risk of clinical (HR, 0.866; 95% CI, 0.054-13.853) or radiographic (HR, 0.959; 95% CI, 0.059-15.474) progression vs those with stage I disease. Weibull profiling revealed 96.9%, 94.6%, and 93.1% successful mandibular ORN arrest at 1, 3, and 5 years, respectively. The major complication rate was 1.9%. Mean (SD) length of stay was 2.7 (0.0-7.0) days. Mean (SD) radiographic follow-up was 29.3 (30.7) months. Conclusions and Relevance: The findings of this large retrospective patient case series support the continued success of the ALTFL rescue flap technique, a safe and highly effective long-term treatment for mandibular ORN in carefully selected patients.

OBJECTIVES: Tall cell variant (TCV) papillary thyroid cancer (PTC) is a subtype of PTC associated with aggressive tumor behavior, advanced stage, and higher rates of recurrence and mortality. The present study aimed to test an established dynamic risk stratification tool in the TCV population, with the goal of better predicting the postoperative course of these patients. STUDY DESIGN: Retrospective chart review. METHODS: A total of 94 patients with TCV who underwent total thyroidectomy with radioactive iodine ablation were retrospectively reviewed from 1998 through 2020. Biochemical, structural, and overall response to treatment was determined for each patient, based on postoperative thyroglobulin levels and imaging findings. Primary outcomes were locoregional and distant recurrence, presence of disease at final follow-up, need for additional intervention, and disease-specific mortality. RESULTS: Patients with TCV who were stratified as having an excellent overall response to treatment had lower rates of locoregional recurrence than indeterminate, biochemical incomplete, and structural incomplete responses (2.0%, 33.3%, 55.0%, and 85.7% at 5 years respectively, p < 0.001). The same was true for distant recurrence as well (2.0%, 9.0%, 35.1%, and 42.9%, p < 0.001). An excellent response was also associated with lower rates of presence of disease at final follow-up, need for additional intervention, and disease-specific mortality. CONCLUSIONS: Although TCV is an aggressive subtype associated with worse clinical outcomes than classical PTC, patients with an excellent overall response to treatment have significantly improved outcomes when compared to indeterminate, biochemical incomplete, and structural incomplete responses.

Importance: Survival outcomes for anaplastic thyroid cancer (ATC), the most aggressive subtype of thyroid cancers, have remained poor. However, targeted therapies and immunotherapies present new opportunities for treatment of this disease. Evaluations of survival outcomes over time with new multimodal therapies are needed for optimizing treatment plans. Objective: To evaluate the association of treatment strategies and tumor characteristics with overall survival (OS) among patients with ATC. Design, Setting, and Participants: This retrospective case series study evaluated the survival outcomes stratified by treatment strategies and tumor characteristics among patients with ATC treated at a tertiary level academic institution from January 1, 2000, to December 31, 2021. Demographic, tumor, treatment, and outcome characteristics were analyzed. Kaplan-Meier method and log rank test modeled OS by treatment type and tumor characteristics. Data were analyzed in May 2022. Main Outcomes and Measures: Overall survival (OS). Results: The study cohort comprised 97 patients with biopsy-proven ATC (median [range] age at diagnosis, 70 [38-93] years; 60 (62%) female and 85 [88%] White individuals; 59 [61%] never smokers). At ATC diagnosis, 18 (19%) patients had stage IVA, 19 (20%) had stage IVB, and 53 (55%) had stage IVC disease. BRAF status was assessed in 38 patients; 18 (47%) had BRAF-V600E variations and 20 (53%), BRAF wild type. Treatment during clinical course included surgery for 44 (45%) patients; chemotherapy, 41 (43%); definitive or adjuvant radiation therapy, 34 (RT; 35%); and targeted therapy, 28 (29%). Median OS for the total cohort was 6.5 (95% CI, 4.3-10.0) months. Inferior OS was found in patients who did not receive surgery (hazard ratio [HR], 2.12; 95% CI, 1.35-3.34; reference, received surgery), chemotherapy (HR, 3.28; 95% CI, 1.99-5.39; reference, received chemotherapy), and definitive or adjuvant RT (HR, 2.47; 95% CI, 1.52-4.02; reference, received definitive/adjuvant RT). On multivariable analysis, age at diagnosis (HR, 1.03; 95% CI, 1.01-1.06), tumor stage IVC (HR, 2.65; 95% CI, 1.35-5.18), and absence of definitive or adjuvant RT (HR, 1.90; 95% CI, 1.01-3.59) were associated with worse OS. Conclusions and Relevance: This retrospective single-institution study found that lower tumor stage, younger age, and the ability to receive definitive or adjuvant RT were associated with improved OS in patients with ATC.

BACKGROUND: Resected oral cavity carcinoma defects are often reconstructed with osteocutaneous or soft-tissue free flaps, but risk of osteoradionecrosis (ORN) is unknown. METHODS: This retrospective study included oral cavity carcinoma treated with free-tissue reconstruction and postoperative IMRT between 2000 and 2019. Risk-regression assessed risk factors for grade ≥2 ORN. RESULTS: One hundred fifty-five patients (51% male, 28% current smokers, mean age 62 ± 11 years) were included. Median follow-up was 32.6 months (range, 1.0-190.6). Thirty-eight (25%) patients had fibular free flap for mandibular reconstruction, whereas 117 (76%) had soft-tissue reconstruction. Grade ≥2 ORN occurred in 14 (9.0%) patients, at a median 9.8 months (range, 2.4-61.5) after IMRT. Post-radiation teeth extraction was significantly associated with ORN. One-year and 10-year ORN rates were 5.2% and 10%, respectively. CONCLUSIONS: ORN risk was comparable between osteocutaneous and soft-tissue reconstruction for resected oral cavity carcinoma. Osteocutaneous flaps can be safely performed with no excess concern for mandibular ORN.

OBJECTIVE: Patients with recurrent oropharyngeal cancer can achieve survival benefits from surgical salvage, and often require simultaneous free-flap reconstruction. Resection and reconstruction can impact function, leading to tube dependence. PRIMARY OBJECTIVE: describe rates of tracheostomy and gastrostomy tube dependence after oropharyngeal resection and free flap after prior radiation. SECONDARY OBJECTIVE: evaluate patient, tumor, and treatment factors associated with tube dependence. STUDY DESIGN: Retrospective, multi-institutional cohort study. Patients treated from 2003 to 2020. Average follow-up 21.4 months. SETTING: Five tertiary care centers. METHODS: Consecutive cohort of patients undergoing resection and simultaneous free-flap reconstruction for oropharyngeal squamous cell carcinoma after head and neck radiation. PRIMARY OUTCOMES: gastrostomy tube dependence and tracheostomy or tracheostoma 1 year after surgery. Univariable and multivariable logistic regression were performed to identify factors associated with dependence. RESULTS: 89 patients underwent oropharyngectomy and free-flap reconstruction; 18 (20%) underwent total laryngectomy as part of tumor extirpation. After surgery, 51 patients (57%) lived 12 months. Among patients alive at 12 months, 22 (43%) were at least partially-dependent on gastrostomy tube, and 15 (29%) had either tracheostomy or tracheostoma. On multivariable analysis, extensive glossectomy (OR 16.6, 95% CI 1.83-389, p = 0.026) and total laryngectomy (OR 11.2, 95% CI 1.71-105, p = 0.018) were associated with long-term gastrostomy tube. No factors were associated with long-term tracheostomy on multivariable analysis. CONCLUSION: Even among long-term survivors after salvage resection and free-flap reconstruction, rates of tube dependence are significant. This multi-institutional review is the largest such study to the date and may help inform shared decision-making. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:2141-2147, 2023.

Importance: Tall cell morphology (TCM) is a rare and aggressive variant of papillary thyroid carcinoma (PTC) that has been associated with poor outcomes; however, the risk factors for worse survival are not well characterized. Objective: To identify prognostic factors associated with cancer recurrence and death in patients with PTC-TCM. Design, Setting, and Participants: All patients treated for PTC-TCM at a single tertiary-level academic health care institution from January 1, 1997, through July 31, 2018, were included. Tall cell variant (TCV) was defined as PTC with TCM of 30% or more; and tall cell features (TCF) was defined as PTC with TCM of less than 30%. Patients with other coexisting histologic findings and/or nonsurgical management were excluded. Clinicopathologic features associated with worse outcomes were identified using Kaplan-Meier and Cox proportional-hazards model. Data were analyzed from March 1, 2018, to August 15, 2018. Main Outcomes and Measures: Locoregional recurrence-free survival (LRRFS), distant recurrence-free survival (DRFS), and overall survival (OS) after surgery. Results: A total of 365 patients (median [range] age, 51.8 [15.9-91.6] years; 242 [66.3%] female) with PTC-TCM (TCV, 32%; TCF, 68%) were evaluable. Total thyroidectomy was performed in 336 (92%) patients; 19 (5.2%) received radiotherapy; and 15 (4.1%) received radioactive iodine. Clinical features were pT3 or T4, 65%; node-positive, 53%; and positive surgical margins, 24%. LRRFS at 1-, 3-, 5-, and 10-year was 95%, 87%, 82%, and 73%, respectively. On multivariable analysis, male sex and age were not independent predictors of inferior 5-year LRRFS, whereas positive surgical margins (HR, 3.5; 95% CI, 2.0-6.3), positive lymph nodes (HR, 2.8; 95% CI, 1.4-5.8), and primary tumor size of 3 cm or more (HR, 3.3; 95% CI, 1.4-7.8) were strongly associated with worse LRRFS. Age 55 years or older (HR, 3.2; 95% CI, 1.5-7.0), male sex (HR 4.5; 95% CI, 2.1-10.0), positive surgical margins (HR, 2.7; 95% CI, 1.2-6.0), nodal positivity (HR, 3.1; 95% CI, 1.3-7.7), tumor diameter of 1.5 cm or more (HR, 20.6; 95% CI, 2.8-152.1), and TCV vs TCF (HR, 3.1; 95% CI, 1.5-6.7) were associated with worse DRFS. Male sex (HR, 3.1; 95% 1.4-6.8) and tumor diameter of 1.5 cm or more (HR, 2.8; 95% CI, 1.0-7.4) were associated with worse OS. A findings-based nomogram was constructed to predict 10-year LRRFS (C index, 0.8). Conclusions and Relevance: This retrospective cohort study found that in patients with PTC-TCM, positive surgical margins, node positive disease, and tumor size of 3 cm or more were risk factors for worse LRRFS. Intensified locoregional therapy, including adjuvant radiation, may be considered for treating these patients.

OBJECTIVE: Organ preservation (OP) treatment for advanced laryngeal cancer has increased compared to primary total laryngectomy. Our study compares oncologic and functional outcomes between these approaches. STUDY DESIGN: Retrospective cohort study. SETTING: Single tertiary care institution. METHODS: Retrospective review of patients receiving primary total laryngectomy or OP for laryngeal cancer between 1/1/2000 and 12/31/2018. RESULTS: A total of 118 patients received primary total laryngectomy and 119 received OP. Overall survival was similar between total laryngectomy and OP. When stratified by T stage, disease-free survival was worse among T3 patients receiving OP versus total laryngectomy. In T3 patients, 28 OP patients experienced local recurrence (28.9%) compared to 3 total laryngectomy patients (7.1%; p < 0.01). In total, 20 OP patients with local recurrence received salvage surgery. These patients had similar overall survival to patients who underwent initial total laryngectomy (TL). About 14 OP patients with local recurrence did not receive salvage surgery. About 89 (75.4%) TL patients achieved normal diet as compared to 64 (53.8%) OP patients (p < 0.001). In TL patients, 106 (89.8%) received primary or secondary tracheoesophageal-prosthesis, 82 (77.4%) of whom achieved completely understandable speech. CONCLUSIONS: There was no difference in survival by treatment in T4 patients, possibly because of strict patient selection. However, disease-free survival was worse in T3 patients receiving OP, likely due to a high local recurrence rate. Approximately 40% of patients with local recurrence were not eligible for salvage laryngectomy. TL patients had comparable swallowing and speech outcomes with OP patients.

BACKGROUND: We sought to determine whether detection of cartilage invasion (CI) by computed tomography predicts oncologic outcomes after primary total laryngectomy. METHODS: Retrospective cohort study comparing oncologic outcomes between radiologic versus pathologic diagnosis. RESULTS: Assessment of clear CI versus gestalt CI resulted in 84% versus 48% specificity, 90.9% versus 80.3% positive predictive value (PPV), 60.6% versus 80.3% sensitivity, 44.7% versus 48% negative predictive value (NPV), respectively. Disease-free survival (DFS) was similar between cT4a and cT3/cT2 patients (p = 0.87). DFS trended towards superiority among pT3/pT2 versus pT4a patients (p = 0.18). DFS was similar among patients with CI on radiologist gestalt versus no CI (p = 0.94). Histologically confirmed CI was associated with a hazard ratio (HR) of 1.46 (p = 0.27), gestalt CI 1.13 (p = 0.70), and clear CI 1.61 (p = 0.10) for DFS. CONCLUSION: Gestalt determination of CI results in high sensitivity but low specificity, while clear determination of CI results in moderate sensitivity and high specificity.

BACKGROUND AND AIM: Poorly differentiated thyroid cancer (PDTC) is a rare but aggressive subtype of thyroid cancer that portends a poor prognosis. There remains a paucity of literature on PDTC outcomes. The aim of our study was to evaluate outcomes of PDTC in our tertiary care facility. PATIENTS AND METHODS: We identified all histologically confirmed PDTC cases from 1997-2018 treated at our Institution and collected data points in an IRB-approved registry. We then conducted a retrospective study to assess outcomes and identified factors associated with inferior outcomes. RESULTS: Twenty-three patients were identified with a median age at diagnosis of 60 years (range=39-89 years). Nineteen (83%) underwent total thyroidectomy. Eight (42%) patients had lymph node dissections and 2 (11%) underwent adjuvant radiation. Thirteen (68%) patients were treated with radioactive iodine (RAI). Those who underwent total thyroidectomy had a median overall survival (mOS) of 88 months, 5 year-OS of 56%, 5 year-local recurrence-free survival (LRFS) of 45%, and 5 year-distant recurrence-free survival (DRFS) of 36%. T4 disease had worse mOS (14 vs. 87 m, p=0.0082), and 5 year-LRFS rate (12 vs. 74%, p=0.0312) compared to T1-3. N0 disease had an improved mOS (172 vs. 32 m, p=0.0013), 5 year-LRFS rate (63 vs. 17%, p=0.0033), and 5 year-DRFS (57 vs. 0%, p=0.0252). Eight out of 23 patients (35%) were alive at last follow-up, with a median of 68 months (range=20-214). The most common cause of death was distant recurrence (73%). Six patients received systemic therapy with various tyrosine kinase inhibitors with a median duration on treatment of 7 months (range=1-30 months). CONCLUSION: Advanced T and N stage were factors associated with significantly inferior outcomes. While select patients benefited with systemic treatment, it remains unclear if intensified locoregional therapy should be considered in patients with PDTC.
