RESUMO
BACKGROUND: De-intensified treatment strategies for early human papillomavirus-positive (HPV+) oropharynx cancer (OPC) rely on selecting patients with an excellent prognosis. The criterion for enrollment in current de-intensification trials is ≤10 pack-years. More nuance to the pack-year criteria may expand enrollment, improve patient outcomes, and prevent overtreatment. It was hypothesized that patients with more than 10 pack-years may experience favorable outcomes if smoking cessation has been achieved. METHODS: From an institutional review board-approved database, patients with HPV+ oropharyngeal squamous carcinoma treated definitively with radiation with or without chemotherapy were retrospectively identified. Patients with a history of smoking who were eligible for national de-intensification trials were included (cT1-2N1-2b or T3N0-2b [American Joint Committee on Cancer, seventh edition]). Cox regression with penalized smoothing splines was used to evaluate nonlinear effects of cessation. Recursive partitioning analysis (RPA) was used to objectively search for relationships between the 2 colinear variables (pack-years and time since cessation). RESULTS: Among 330 patients meeting the inclusion criteria, 130 (40%) were never smokers, 139 (42%) were former smokers, and 61 (18%) were current smokers. With standard therapy, all former smokers achieved a progression-free survival (PFS) rate higher than 91%, regardless of pack-year exposure. Nonlinear Cox regression demonstrated that more recent cessation was associated with significantly worse PFS even among those with ≤20 pack-years. RPA demonstrated that only current smokers experienced a 2-year PFS rate lower than 91%; former smokers, regardless of pack-years, experienced a 2-year PFS rate higher than 91%. CONCLUSIONS: The 10-pack-year rule may not apply to all early HPV+ OPCs, particularly for former smokers. Future randomized de-intensification trials should consider a broader and more nuanced approach until the predictive role of smoking status is established.

BACKGROUND: Time to treatment initiation (TTI) is increasing and is associated with worsening survival. In the current study, the authors sought to identify a mechanism for this relationship by assessing the effect of TTI on clinical-to-pathologic upstaging in patients with head and neck squamous cell carcinoma (HNSCC). METHODS: Using the National Cancer Data Base, the authors analyzed patients receiving definitive surgery for SCC of the oral cavity, oropharynx, larynx, and hypopharynx from 2005 through 2014. The primary outcome was T, N, or stage group upstaging, defined as higher pathologic stage than clinical stage. TTI was defined as the time between diagnosis and surgery. Multivariable logistic and Cox proportional hazards regression modeled upstaging and survival, respectively. RESULTS: Cohorts of 60,194 patients, 51,380 patients, and 52,980 patients, respectively, with complete T, N, and stage group data were included. N upstaging was most common (18.6%), followed by stage group (17.4%) and T (12.1%) upstaging; all types were predicted by TTI. Compared with a TTI of 1 to 6 days, TTIs as short as 7 to 13 days (odds ratio, 1.20; P = .038) or ≥ 70 days (odds ratio, 2.04; P < .001) were found to predict T upstaging, a finding that is consistent for N and stage group upstaging. Using restricted cubic splines, relative odds of T and stage group upstaging escalated to 2.25 and 1.93, respectively, at a TTI of 365 days. In survival analyses, T (hazard ratio [HR], 1.53), N (HR, 1.88), and stage group (HR, 1.69) upstaging all predicted mortality (P < .001), whereas TTI only predicted mortality after 70 days (HR, 1.11; P = .023). CONCLUSIONS: Tumor progression, measured by clinical-to-pathologic upstaging, increases mortality for patients with HNSCC experiencing treatment delays.

OBJECTIVE: Eagle syndrome, a spectrum of disease resulting from an elongated styloid process and/or calcified stylohyoid ligament, lacks standardized recommendations regarding indications for surgical intervention and approach. STUDY DESIGN: Retrospective cohort study. SETTING: Single tertiary care institution. SUBJECTS: Patients treated surgically for Eagle syndrome between January 2011 and June 2017. METHODS: Patients were diagnosed with Eagle syndrome based on thorough clinical workup and assessment. The primary outcome was improvement in pain severity following surgery, with complete resolution of pain being considered clinically meaningful. Wilcoxon rank-sum tests and Fisher's exact were used to compare numerical and categorical variables, respectively. RESULTS: Twenty-one patients were diagnosed with Eagle syndrome and underwent surgical resection of the styloid process. Patients most often complained of neck pain (81%), throat pain (62%), and ear pain (48%). Among these patients, 57% of procedures featured a transcervical approach, while the remaining 43% were transoral. The vast majority (90%) of patients experienced improvement in pain severity from a median of 6.0 before surgery to 0.0 afterwards (pâ¯<â¯0.01) as 62% experienced complete resolution. Using multivariable linear regression to model changes in pain severity, neck pain (ßâ¯=â¯-1.69, pâ¯<â¯0.01) and jaw pain (ßâ¯=â¯-0.93, pâ¯=â¯0.03) predicted greater relief, while headache (ßâ¯=â¯0.82, pâ¯=â¯0.04) predicted an inferior response. Adverse events were uncommon and typically resolved within three months, with 24% experiencing first bite syndrome and 19% reporting numbness. CONCLUSIONS: Transcervical and transoral styloidectomy are effective treatments for Eagle syndrome with minimal adverse effects. Patients with classic symptoms of neck or jaw pain benefit most from surgery.

PURPOSE: To determine the accuracy of intraoperative frozen section analysis on thyroidectomy specimens stratified by the Bethesda classification scheme and its utility for intraoperative decision-making. STUDY DESIGN: Retrospective chart review. METHODS: A retrospective review was performed on all patients who underwent thyroidectomy or thyroid lobectomy with intraoperative frozen sections at a tertiary care academic center from 2009 to 2015. RESULTS: There were 74 total patients who underwent partial or total thyroidectomy with intraoperative frozen section analysis of a thyroid nodule whom had previously undergone a thyroid fine needle aspiration of the nodule. The sensitivity, specificity, positive predictive value, and negative predictive value for a thyroid frozen section with respect to its prediction for malignancy was 81%, 95%, 98%, and 66%, respectively, with a diagnostic accuracy of 85%. For 37 patients with an indeterminate cytologic diagnosis on fine needle aspiration (Bethesda categories III-V), the sensitivity, specificity, positive predictive value, and negative predictive value for a thyroid frozen section was 81%, 91%, 95%, and 67%, respectively, with a diagnostic accuracy of 84%. False positives and false negatives resulted in 1 completion thyroidectomy for benign pathology and 3 reoperations for malignancy not discovered on frozen section. CONCLUSION: While intraoperative frozen sections on thyroid specimens may be helpful if positive, the false negative rate remains high. There appears to be limited value in routine frozen sections to guide clinical management and decision-making in the era of the Bethesda system.

BACKGROUND: Human papillomavirus-related (HPV+) oropharyngeal cancer is a rapidly emerging disease with generally good prognosis. Many prognostic algorithms for oropharyngeal cancer incorporate HPV status as a stratification factor, rather than recognising the uniqueness of HPV+ disease. The International Collaboration on Oropharyngeal cancer Network for Staging (ICON-S) aimed to develop a TNM classification specific to HPV+ oropharyngeal cancer. METHODS: The ICON-S study included patients with non-metastatic oropharyngeal cancer from seven cancer centres located across Europe and North America; one centre comprised the training cohort and six formed the validation cohorts. We ascertained patients' HPV status with p16 staining or in-situ hybridisation. We compared overall survival at 5 years between training and validation cohorts according to 7th edition TNM classifications and HPV status. We used recursive partitioning analysis (RPA) and adjusted hazard ratio (AHR) modelling methods to derive new staging classifications for HPV+ oropharyngeal cancer. Recent hypotheses concerning the effect of lower neck lymph nodes and number of lymph nodes were also investigated in an exploratory training cohort to assess relevance within the ICON-S classification. FINDINGS: Of 1907 patients with HPV+ oropharyngeal cancer, 661 (35%) were recruited at the training centre and 1246 (65%) were enrolled at the validation centres. 5-year overall survival was similar for 7th edition TNM stage I, II, III, and IVA (respectively; 88% [95% CI 74-100]; 82% [71-95]; 84% [79-89]; and 81% [79-83]; global p=0·25) but was lower for stage IVB (60% [53-68]; p<0·0001). 5-year overall survival did not differ among N0 (80% [95% CI 73-87]), N1-N2a (87% [83-90]), and N2b (83% [80-86]) subsets, but was significantly lower for those with N3 disease (59% [51-69]; p<0·0001). Stage classifications derived by RPA and AHR models were ranked according to survival performance, and AHR-New was ranked first, followed by AHR-Orig, RPA, and 7th edition TNM. AHR-New was selected as the proposed ICON-S stage classification. Because 5-year overall survival was similar for patients classed as T4a and T4b, T4 is no longer subdivided in the re-termed ICON-S T categories. Since 5-year overall survival was similar among N1, N2a, and N2b, we re-termed the 7th edition N categories as follows: ICON-S N0, no lymph nodes; ICON-S N1, ipsilateral lymph nodes; ICON-S N2, bilateral or contralateral lymph nodes; and ICON-S N3, lymph nodes larger than 6 cm. This resembles the N classification of nasopharyngeal carcinoma but without a lower neck lymph node variable. The proposed ICON-S classification is stage I (T1-T2N0-N1), stage II (T1-T2N2 or T3N0-N2), and stage III (T4 or N3). Metastatic disease (M1) is classified as ICON-S stage IV. In an exploratory training cohort (n=702), lower lymph node neck involvement had a significant effect on survival in ICON-S stage III but had no effect in ICON-S stage I and II and was not significant as an independent factor. Overall survival was similar for patients with fewer than five lymph nodes and those with five or more lymph nodes, within all ICON-S stages. INTERPRETATION: Our proposed ICON-S staging system for HPV+ oropharyngeal cancer is suitable for the 8th edition of the Union for International Cancer Control/American Joint Committee on Cancer TNM classification. Future work is needed to ascertain whether T and N categories should be further refined and whether non-anatomical factors might augment the full classification. FUNDING: None.

BACKGROUND: Immunosuppressed patients have higher rates of cutaneous squamous cell carcinoma of the head and neck. OBJECTIVE: This study reviews the effect of immune status on disease characteristics and treatment outcomes. METHODS: Patients with cutaneous squamous cell carcinoma of the head and neck treated with surgery and postoperative radiotherapy between 2000 and 2011 were included. Immunosuppressed patients underwent prior organ transplantation or chemotherapy. Baseline variables were compared using χ(2) and unpaired t tests. Overall survival and disease-free survival were calculated using the Kaplan-Meier method. RESULTS: In this study of 59 patients, 38 (64%) were immunocompetent and 21 (36%) were immunosuppressed. Most patients had recurrent tumors (63%) and node-positive disease (61%), which were well balanced between the groups. Poorly differentiated tumors (62% vs 21%; P = .009), lymphovascular invasion (29% vs 11%; P = .08), and extracapsular extension (57% vs 41%; P = .09) were more frequent in the immunosuppressed group. Two-year disease-free survival (45% vs 62%) and 2-year overall survival (36% vs 67%) were inferior for immunosuppressed patients. LIMITATIONS: Limitations include single institution, retrospective study with small sample size, and potential referral bias. CONCLUSIONS: Immunosuppressed patients with cutaneous squamous cell carcinoma of the head and neck more frequently present with high-risk pathologic features and inferior outcomes. Early multidisciplinary assessment and alternate management strategies merit prospective investigation.

OBJECTIVES: Salivary gland malignancies comprise a heterogeneous group of pathologies, for which treatment of the clinically negative neck may vary depending on numerous factors. Herein we present data on occult nodal metastases (ONM) as well as survival and recurrence from a large series of cN0 salivary gland malignancies. METHODS: Retrospective chart review was conducted on 532 patients, with 389 patients with major salivary gland cancers and 143 patients with minor salivary gland cancers. Demographic and treatment data were included and rates of ONM, overall survival, local recurrence, regional recurrence, and distant recurrence were analyzed. RESULTS: We found that the overall rate of ONM for parotid was 27% (63/235), for submandibular/sublingual was 35% (18/52), and for minor was 15% (4/26). Analysis of ONM rate at each nodal level was also performed, finding higher rates of level IV and V ONM than prior studies. Submandibular/sublingual and minor salivary gland malignancies showed a predominance of ONMs at levels I-III. Our survival and recurrence rates were similar to those found in previous studies. CONCLUSION: Our data also demonstrate a predominance of ONM in levels I-III for submandibular/sublingual and minor salivary gland cancers, suggesting elective dissection in these levels.

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
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: Little is known about prognostic factors and treatment outcomes in young patients with anaplastic thyroid cancer (ATC). The goal of this study is to define the clinical features of this subgroup. MATERIAL AND METHODS: Patients age 55 or younger with either ATC or well-differentiated thyroid cancer (WDTC) with anaplastic changes were identified using electronic medical record at the Cleveland Clinic. The same number of patients older than 55 was randomly selected to serve as control. Progression-free survival (PFS), overall survival time (OST) and cause-specific mortality (CSM) were measured against age, tumor histology, extent of disease, and treatment modalities. RESULTS: Twelve patients age 55 or younger were identified. The median age was 51 years. Four patients had WDTC with anaplastic components--mixed tumor group (MTG). Their median PFS, OST, and CSM at 24 months were 21.5 months, 51 months, and 25%, respectively. For the other 8 patients who had pure ATC, their median PFS, OST, and CSM were 3.5 months, 6 months, and 100%, respectively. Patients in the MTG had better survival compared to the pure ATC and control group in terms of PFS (p = 0.0047 and p = 0.0053), OST (p = 0.0028 and p = 0.0029) and the CSM at 24 months (p = 0.0339 and p = 0.0096). In the pure ATC group, patients with positive cervical lymph node and distant metastases had similar overall survival outcomes (6 vs. 8 months, p = 0.4995). CONCLUSION: Prognostic factors favoring survival in young patients with ATC include ATC arising within WDTC. Once full anaplastic transformation occurs, age was not a significant factor in survival.

SIGNIFICANCE STATEMENT: Pharyngeal fistulas to the cervical spine resulting in vertebral osteomyelitis are a rare, yet clinically important, complication of total laryngectomy performed in conjunction with chemoradiotherapy or radiation therapy. This complication is likely underdiagnosed and can have a high mortality rate. It is very important that clinicians are aware of this complication as early diagnosis and management may improve patient outcomes.

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.

OBJECTIVES: Investigate outcomes following oral cavity and oropharyngeal salvage surgery. METHODS: Adult patients who underwent salvage surgery for recurrent squamous cell carcinoma of the oral cavity and oropharynx from 1996 to 2018 were analyzed using multivariable Cox proportional hazards regression. Disease-free survival (DFS), overall survival (OS), associated factors, and basic quality measures were analyzed. RESULTS: One hundred and eight patients (72% oral cavity, 28% oropharynx) were followed for a median of 17.9 months. Median DFS and OS were 9.9 and 21 months, respectively. Surgery with adjuvant chemoradiotherapy compared to surgery alone (hazard ratio [HR] = 0.15, 95% confidence interval [CI]: 0.03-0.78) and negative margins (HR = 0.36, 95% CI: 0.14-0.90) were associated with better DFS, while lymphovascular space invasion (LVSI) (HR = 2.66, 95% CI: 1.14-6.19) and higher stage (III vs. I-II, HR = 3.94, 95% CI: 1.22-12.71) were associated with worse DFS. Higher stage was associated with worse OS (HR = 3.79, 95% CI: 1.09-13.19). Patients were hospitalized for a median of 8 days with 24% readmitted within 30 days. A total of 72% and 38% of patients, respectively, underwent placement of a feeding tube or tracheostomy. CONCLUSIONS: After oral cavity and oropharyngeal salvage surgery, adjuvant chemoradiotherapy, negative margins, negative LVSI, and lower stage were associated with a lower risk of recurrence. Only lower-stage disease was associated with improved survival. The majority of patients had feeding tubes, half underwent free tissue transfer, a third required tracheostomy, and a quarter was readmitted. LEVEL OF EVIDENCE: 3 Laryngoscope, 132:1984-1992, 2022.

BACKGROUND/AIM: Hypofractionated radiation therapy is not commonly used in head and neck cancers (HNC) due to increased toxicity observed in historical cohorts. This study reviews our institutional experience using hypofractionated intensity modulated radiation therapy (H-IMRT) for HNC. PATIENTS AND METHODS: A retrospective cohort study of 56 patients with HNC treated with H-IMRT with ≥50 Gy in 20 fractions was conducted. The primary outcomes were acute and late toxicity. RESULTS: Two-year locoregional control was 87% and median overall survival was 46 months. There were no acute or late grade 4 or 5 toxicities. Acute grade 2 and 3 toxicity was seen in 79% (N=44) and 25% (N=14), respectively. Late grade 2 toxicity was seen in 9% (N=5). No patients required the placement of a feeding tube or tracheostomy. CONCLUSION: H-IMRT for the definitive or post-operative treatment of HNC using ≥50 Gy in 20 fractions appears safe and well tolerated with modest toxicity.

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.

OBJECTIVES: To explore the influence of treatment package time(TPT) in high-risk oral cavity squamous cell carcinoma(OCSCC) receiving adjuvant radiotherapy with concurrent chemotherapy(CRT). MATERIALS AND METHODS: We queried our multi-institutional OCSCC collaborative database for cases diagnosed between 2005 and 2015 who underwent surgery followed by adjuvant CRT. All patients had high-risk features: extranodal extension(ENE) and/or positive surgical margin(PM). TPT was days between surgery to last radiotherapy fraction. Kaplan-Meier curves, log-rank p-values and multivariate analysis(MVA) were used to investigate the impact of TPT on overall(OS), disease-free(DFS), locoregional failure-free(LRFS) and distant metastases-free(DMFS) survival. RESULTS: We identified 187 cases: median age 58 (range, 24-87 years), males 66%, and ever smokers 69%. ENE and PM were detected in 85% and 32%, and oral tongue and floor of the mouth constituted 49% and 18%, respectively. Median radiotherapy and cisplatin doses received were 66 Gy and 200 mg/m2. Overall, median TPT was 98 (range, 63-162 days). OS was worse for TPT > 90-days (n = 134) than TPT ≤ 90 (n = 53) at two-(65% vs. 71%) and five-years (45% vs. 62%); p = 0.05, with similar results for DFS. No influence on LRFS or DMFS was noted. More lymph nodes(LN) dissected(P = 0.039), T3-4 disease(P = 0.017), and unplanned reoperations(P = 0.037) occurred with TPT > 90-days. On MVA, TPT in 10-day increments was independently detrimental for OS (Hazard Ratio: 1.14; 95 %Confidence Interval [1-1.28]; P = 0.043), perineural invasion, age and positive LN (p < 0.05 for all). CONCLUSION: In one of the largest multi-institutional cohorts, TPT > 90-days predicted worse OS for high-risk OCSCC receiving adjuvant CRT. All efforts are needed to optimize perioperative care and baseline conditions for favorable outcomes.

OBJECTIVES: To assess risk factors and non-thyroid specific postoperative complications for thyroid lobectomy compared to total thyroidectomy. METHODS: A retrospective, cross-sectional study of adults undergoing a lobectomy or total thyroidectomy using the National Surgical Quality Improvement Program database between 2005 and 2017. Patients not treated by otolaryngologists or general surgeons and with unknown demographic variables were excluded. RESULTS: A total of 106 915 patients were analyzed, 64 763 total thyroidectomies and 42 152 lobectomies. Multivariable analysis demonstrated that total thyroidectomy patients were half as likely to return to the operating room (OR = 0.491 (95%CI 0.445-0.542), P < .001). Within this cohort, patients at greater risk for reoperation had a history of hypertension (OR = 1.225 (95%CI 1.090-1.376), P < .001), a malignant pathology (OR = 1.921 (95%CI 1.734-2.128), P < .001), and smoked (OR = 1.237 (95%CI 1.087-1.407), P = .001). Conversely, diabetes and body mass index did not impact the rate of reoperation when assessing total thyroidectomy and lobectomy. The most frequent non-thyroid specific complications in total thyroidectomy were unplanned intubation (0.5%), urinary tract infection (0.3%), and superficial surgical site infection (0.3%). In thyroid lobectomy, the most common complications were superficial surgical site infection (0.3%) and urinary tract infection (0.2%). CONCLUSIONS: Our multi-institutional study indicates specific risk factors for returning to the operating room that may warrant closer follow up after surgery for total thyroidectomy or thyroid lobectomy. We also identified the most common post-operative complications. During pre-operative planning, these findings should be considered by thyroid surgeons to help mitigate risk to patients.

OBJECTIVE: To characterize and assess the non-thyroid-specific postoperative complications of completion thyroidectomy as compared with total thyroidectomy. STUDY DESIGN: Retrospective analysis: 2005 to 2017. SETTING: National Surgical Quality Improvement Program database. SUBJECTS AND METHODS: Patients aged >18 years receiving a completion or total thyroidectomy were eligible for inclusion. Patients not treated by otolaryngologists or general surgeons and with unknown demographic variables were excluded. RESULTS: A total of 70,638 patients were analyzed, representing 64,763 total thyroidectomies and 5875 completion thyroidectomies. The 30-day mortality rate was 0.1% for both procedures (P > .05). Overall, 1.7% and 1.4% of patients undergoing total and completion thyroidectomies experienced at least 1 complication (P > .05), while 1.2% and 0.9% had a postoperative medical complication (P = .0186), respectively. On multivariable analysis, patients undergoing total thyroidectomies were significantly more likely to return to the operating room (odds ratio [OR], 1.36; 95% CI, 1.04-1.80; P = .027) and to be readmitted (OR, 1.45; 95% CI, 1.16-1.81; P = .001). Adjusted analysis also demonstrated that patients undergoing total thyroidectomies were more likely to be inpatients (OR, 1.17; 95% CI, 1.11-1.24; P < .001), be treated by nonotolaryngologists (OR, 1.36; 95% CI, 1.29-1.45; P < .001), and smoke (OR, 1.22; 95% CI, 1.13-1.33; P < .001). CONCLUSION: National data suggest that total and completion thyroidectomies are relatively safe procedures but that completion thyroidectomies are associated with lower rates of postoperative complications. These findings may play a role in determining treatment plans for patients and optimizing risk reduction.

OBJECTIVES/HYPOTHESIS: Evaluate the impact and accuracy of clinical laryngeal cancer staging. STUDY DESIGN: Retrospective cohort study. METHODS: Two hundred sixty-five consecutive patients with laryngeal squamous cell carcinoma who underwent total laryngectomy from 2001 to 2017 were studied. Clinical versus pathologic tumor (T) and nodal (N) categories were compared. Logistic regression and Cox proportional hazards analyzed the association of stage change with perioperative factors and outcomes. RESULTS: Forty-seven patients (17.7%, accuracy = 0.969 ± 0.010 [standard error]) changed between T1-2 and T3-4. Sixty-four patients (24.1%, accuracy = 0.866 ± 0.020) had inaccurate N category. Salvage patients were less likely to have stage change (downstage: odds ratio [OR] = 0.20, 95% confidence interval [CI]: 0.08-0.50, P < .001; upstage: OR = 0.41, 95% CI: 0.23-0.74, P = .003), but more likely to have inaccurate nodal category (39.8% vs. 11.7%, P < .001). Patients with stage change tended to have greater odds of positive/close margins (upstage: OR = 1.78, 95% CI: 0.91-3.5, P = .092) and chemotherapy (downstage: OR = 2.21, 95% CI: 0.80-6.14, P = .128; upstage: OR = 1.87, 95% CI: 0.85-4.11, P = .119). Stage change was associated with recurrence (P = .047) with downstaged patients less likely to recur (hazard ratio = 0.26, 95% CI: 0.08-0.82, P = .021). Stage change was not associated with positron emission tomography scan, subsite, time to surgery, or mortality. CONCLUSIONS: A third of laryngeal cancer patients were downstaged or upstaged after laryngectomy with 18% and 24% of clinical T and N categories inaccurate, respectively. Stage change was less common for salvage patients and associated with risk of recurrence. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:559-565, 2021.
