RESUMO
BACKGROUND: Nutritional status and sarcopenia affects the prognosis of head and neck cancers including hypopharyngeal cancer. Hypopharyngeal cancer patients tend to exhibit sarcopenia, which is associated with poor treatment outcomes. This study aims to determine the correlation between nutritional status and sarcopenia, and their prognostic role in surgically treated hypopharyngeal cancer. MATERIALS AND METHODS: Patients who had been diagnosed with squamous cell carcinoma originating from the hypopharynx and underwent surgery between January 2009 and December 2019 were enrolled in this study. The median neutrophil-to-lymphocyte ratio and prognostic nutritional index (PNI) of the cohort were considered the cut-off values. Sarcopenia was evaluated by measuring skeletal muscle index (SMI) at the third lumbar vertebra. Clinical and serological factors predictive of survival outcomes were evaluated. RESULTS: Patients with high PNI showed better 5-year Overall survival (OS) (52.8% vs. 27.2%, p = 0.001) and disease-free survival (DFS) (59.6% vs. 44.6%, p = 0.033) than those with low PNI. Likewise, patients with low SMI showed worse 5-year OS (25.0% vs. 60.9%, p = 0.002) and DFS (42.4% vs. 68.7%, p = 0.034) than patients with high SMI. Among the patients with high PNI, those with sarcopenia displayed significantly worse OS than those with high SMI (78.0% vs. 34.4%, p = 0.049). High PNI with high SMI presented better overall (p = 0.010) and DFS (p = 0.055) than any other group. CONCLUSIONS: Both sarcopenia and PNI were associated with the prognosis of hypopharyngeal cancer. Considering that PNI and sarcopenia indicate the nutritional status, nutritional status may be a significant risk factor. Therefore, nutritional support that ameliorates sarcopenia may improve survival outcomes in surgically treated patients with hypopharyngeal cancer.

OBJECTIVES: We primarily aimed to evaluate whether parotid incidental lesion (PIL) in 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) for staging evaluation of patients with hepatocellular carcinoma (HCC) would represent a possibility of extrahepatic metastasis or second primary malignancy (SPM). Additionally, we explored the incidence of PIL in HCC patients and examined any associated risk factors. METHODS: We retrospectively analyzed patients with HCC who underwent 18F-FDG PET/CT at our institution from 2010 to 2022. The pathological findings of PILs in HCC patients were investigated for confirmatory identification of the risk of HCC metastasis or SPM in parotid gland. Healthy controls received 18F-FDG PET/CT for health screening were also enrolled to compare the incidence of PILs with HCC patients. Various parameters associated with patient demographics and characteristics of HCC were analyzed to find the related factors of PILs. RESULTS: A total of 17,674 patients with HCC and 2,090 healthy individuals who had undergone 18F-FDG PET/CT scans were enrolled in the analyses. Among the 54 HCC patients who underwent pathological confirmation for PILs, benign primary parotid tumor was most commonly observed (n = 43 [79.6%]); however, no malignant lesions were detected, including HCC metastasis. The incidence of PILs was higher in patients diagnosed with HCC compared with the control group (485 [2.7%] vs. 23 [1.1%], p = 0.002). Analysis for the risk factors for PILs revealed that patient age, sex, and positive viral markers were significantly associated with the incidence of PILs in patients with HCC (all p < 0.001). CONCLUSIONS: Our study demonstrates that PILs are more frequently identified in patients with HCC on 18F-FDG PET/CT. However, no malignant PIL, including extrahepatic metastasis of HCC, was identified. Therefore, the presence of PIL should not impede or delay the treatment process for patients with HCC. Additionally, we suggested that for future swift and straightforward differential diagnoses of PIL, the development of additional protocols within the PET/CT imaging could be beneficial.

BACKGROUND: Cervical lymph node metastasis (CLNM) from remote primary sites is rare in head and neck cancer. The efficacy of neck dissection is still being investigated for therapeutic benefits of local management in oligometastasis from non-head and neck cancer. OBJECTIVES: To evaluate the clinical efficacy of neck dissection (ND) in CLNM from distant primary cancers and identify factors contributing to improved survival. MATERIALS AND METHODS: This retrospective case-control study enrolled patients who underwent ND for CLNM from distant primary cancer at Asan Medical Centre between January 2010 and December 2020. We analysed overall survival and association between clinical covariate and survival. RESULTS: The study included 31 (14 males, 17 females) among 114 patients. Ovarian cancer was the most common primary malignancy (32.3%). Patients with fewer than three metastatic lymph nodes, without extranodal extension and with adjuvant therapy after surgery had better survival rates. CONCLUSION AND SIGNIFICANCE: In patients with CLNM from a distant primary cancer, ND is beneficial as local treatment. And adequate selection of patients for ND is pivotal to improve prognosis.

BACKGROUND: Mucoepidermoid carcinoma (MEC) is the most common salivary gland malignancy. This study was designed to identify valuable prognosticator in MEC. METHODS: Histopathologic analysis, immunohistochemistry, and in situ hybridization were performed on 128 carcinomas diagnosed as MEC of the head and neck. RESULTS: Expression of p16 was found in 96 cases (76%) of MEC. Lymphoid stroma was identified in 63 cases (49%). There was a significant correlation between loss of p16 expression and absence of lymphoid stroma. Expression of p16 was significantly associated with better clinicopathologic features. Lymphoid stroma was significantly associated with lower histologic grade. Overall survival (OS) was significantly longer in cases expressing p16 (P = 0.00096) and lymphoid stroma cases (P = 0.0023). Multivariate analysis revealed loss of p16 expression as negative prognosticators for OS. CONCLUSION: Our data showed p16 expression and the presence of lymphoid stroma were significantly associated with good clinical outcomes. Testing for these factors could lead to better prognostication and treatment of patients with MEC.

BACKGROUND: The most common type of carcinoma ex pleomorphic adenoma (CPA) is histologically equivalent to salivary duct carcinoma, which has an apocrine phenotype. Invasive CPA is often accompanied by non-invasive or in situ carcinoma, an observation that suggests the presence of precursor lesions. The aim of this study was to identify candidate precursor lesions of CPA within pleomorphic adenoma (PA). METHODS: Eleven resected cases of CPA with residual PA and 17 cases of PA with atypical changes were subjected to immunohistochemistry (IHC) for p53, human epidermal growth factor receptor 2 (HER2), androgen receptor (AR), pleomorphic adenoma gene 1, gross cystic disease fluid protein-15 (GCDFP-15), and anti-mitochondrial antibody. RESULTS: Invasive or in situ carcinoma cells in all CPAs were positive for AR, GCDFP-15, and HER2. Atypical foci in PAs corresponded to either apocrine or oncocytic changes on the basis of their reactivity to AR, GCDFP-15, and anti-mitochondrial antibody. Atypical cells in PAs surrounding CPAs had an apocrine phenotype without HER2 expression. CONCLUSIONS: Our study identified frequent apocrine changes in residual PAs in CPA cases, suggesting a possible precursor role of apocrine changes. We recommend the use of HER2 IHC in atypical PAs, and that clinicians take HER2 positivity into serious consideration.
RESUMO
Dysphagia and feeding tube dependency commonly occur in patients with laryngeal or hypopharyngeal cancer (LHC) during and after treatment, often leading to poor functional outcomes. Therefore, we examined the factors related to feeding tube dependency among advanced-stage LHC patients undergoing curative surgery. This study included 69 consecutive patients who underwent conservative surgery for previously untreated, advanced-stage LHC (squamous cell carcinoma) between 2006 and 2016. Persistent feeding tube dependency was defined as 1 year or more after treatment completion. Binary logistic regression analysis was used to determine the factors associated with reactive prolonged and persistent feeding tube dependency. Cox proportional hazard regression analysis was used to determine the association between feeding tube dependency and survival. None of the study patients had a prophylactic feeding tube, but 15 (21.7%) patients had reactive feeding tube placement for 3 months or more. A total of 9 (13.0%) patients had persistent feeding tube dependency. Univariate analysis showed that age, tracheostomy, and common terminology criteria for adverse events (CTCAE) ≥ 3 were significantly associated with reactive prolonged and persistent feeding tube dependency (all P < 0.05). In the multivariate analysis, advanced age and CTCAE ≥ 3 remained the independent factors of reactive prolonged and persistent feeding tube dependency (all P < 0.05). Feeding tube dependency was not associated with overall survival or disease-free survival (P > 0.1). Feeding tube dependency might be related to clinical factors, such as age and severe adverse events, in the patients undergoing function-preserving surgery for advanced-stage LHC.

Objective: Hypopharyngeal cancer is managed by either surgical resection or radiation therapy-based treatment. In choosing the treatment modality, the patient's swallowing function should be considered to achieve optimal treatment outcomes. This study aimed to stratify the risk factors predictive of postoperative dysphagia in hypopharyngeal cancer. Study Design: Retrospective study. Setting: Tertiary referral center. Methods: We enrolled 100 patients who were diagnosed with hypopharyngeal cancer and underwent curative surgery between January 2010 and December 2019, and retrospectively reviewed their medical records. Results: Postoperative dysphagia occurred in 29 patients (29%) who required a tracheostomy tube or percutaneous gastrostomy tube for feeding or preventing aspiration; additionally, the overall survival rate was lower in those patients than in those without dysphagia. The univariate analysis revealed that postoperative dysphagia was associated with clinical T stage (p = 0.016), N stage (p = 0.002), and surgical resection extent of the larynx and pharynx (p < 0.001). Patients who underwent total laryngectomy with total/partial pharyngectomy were more likely to have dysphagia than those in the larynx-preserving pharyngectomy groups (odds ratio [OR] = 3.208, 95% confidence interval [CI] 1.283-8.024, p = 0.011). Concerning the posterior pharyngeal wall (PPW), which has an important role in swallowing, patients who underwent resection of ≥1/2 of the PPW were more likely to have dysphagia (OR = 7.467, 95% CI 1.799-30.994, p = 0.003). Conclusions: Surgical resection extent was proportionally associated with dysphagia in hypopharyngeal cancer patients. Patients with smaller lesions but no laryngeal invasion had better postoperative swallowing function than patients with larger lesions or laryngeal involved lesions. Preserving the larynx and hypopharyngeal mucosa (especially the PPW) as much as possible can help preserve postoperative swallowing function.
RESUMO
Objective: Postoperative delirium is known to have various adverse effects on head and neck surgery patients. This study was designed to identify possible risk factors of delirium following long periods of head and neck cancer surgery and to help prevent postoperative delirium. Methods: We enrolled 197 patients who underwent long-time (>6â h) head and neck surgery at the Asan Medical Center from January 2017 to December 2018 in this study. Clinical covariates that may be associated with delirium were analyzed retrospectively using univariate and multivariate analyses. Results: Delirium occurred in 18 patients (9.1%). Within the first 7 days, 16 patients (88.9%) experienced delirium. Upon univariate analysis, delirium was associated with old age (≥75, p = 0.001), past neurological history (p = 0.019), time to ambulation (p = 0.014), and postoperative hospital day (p = 0.048). In multivariate analysis, old age (≥75, odds ratios (OR) 6.16, CI 2.00-19.00, p = 0.002), time to ambulation (OR 1.04, CI 1.01-1.07, p = 0.017), and past neurological history (OR 5.26, CI 1.09-25.37, p = 0.039) were significant risk factors associated with postoperative delirium. Conclusions: Older patients or patients with neurologic history must be attended with care, especially early after surgery. Encouraging early ambulation might lower the incidence of postoperative delirium and, subsequently, reduce adverse effects. This result could benefit patients by helping them avoid undesirable outcomes.
RESUMO
(1) Background: Facial nerve resection with reconstruction helps achieve optimal outcomes in the treatment of facial nerve invasion (FNI) of parotid cancer. Preoperative imaging is crucial to predict facial nerve reconstruction. The radiological findings of CT or MRI may predict FNI in the parotid cancer even without facial paralysis. Methods: We retrospectively reviewed the records of 151 patients without facial nerve paralysis before surgery who had undergone tumor resection. Previously untreated parotid cancers were included. (2) Results: The median follow-up duration was 62 months (range: 24-120 months). The FNI (+) group (n = 30) showed a significantly worse 5-year overall survival compared with the FNI (-) group (75.5 vs. 93.9%; hazard ratio = 4.19; 95% confidence interval: 1.74-10.08; p = 0.001). The tumor margin, tumor size, presence in the anterolateral parotid region (area 3), retromandibular vein involvement, distance from the stylomastoid foramen to the upper tumor margin, and a high tumor grade were significant factors related to FNI in the univariate analysis. A spiculated tumor margin, the tumor size (2.2 cm), and presence in area 3 were factors predicting FNI in the logistic regression model (p = 0.020, 0.005, and 0.050, respectively; odds ratio: 4.02, 6.40, and 8.16, respectively). (3) Conclusions: The tumor size (≥2.2 cm), spiculated margin, and presence in area 3 as presented in CT and MRI may help clinicians preoperatively predict FNI in patients with parotid cancer and establish an appropriate surgical plan.
RESUMO
OBJECTIVES: Obliteration with cauterization of the internal opening of pyriform sinus fistulas, with or without marsupialization, has been a mainstay for preventing recurrence. However, this procedure predisposes patients to recurrence caused by the reopening of the cauterized orifice. We applied suture ligation to secure the closure of the internal orifice following cauterization and evaluated treatment. METHODS: A total of 42 patients were diagnosed with third or fourth branchial cleft anomaly with internal pyriform sinus fistula and treated either with cauterization or with cauterization and suture ligation, between January 2008 and December 2020. The medical records were reviewed to assess demographic characteristics, clinical presentations, diagnoses, surgical treatment, and outcomes. Treatment flow characteristics for intractable patients were analyzed. RESULTS: The median age of onset was 9 years (range, 0-57 years). Neck swelling (n = 32, 76.2%) was commonly encountered symptom, and a history of neck infection was found in 27 patients (64.3%). After initial treatment, 11 cases (56.2%) recurred. Younger age (≤9 years) and thyroid involvement were associated with recurrence (P = .034 and P = .046, respectively). Cauterization with suture ligation presented lower recurrence rate (19.2%) than cauterization only (37.5%, P = .037). Cauterization with suture ligation for recurrent cases (n = 11) showed 81.8% (9/11) of cure rate. Intractable fistulas (n = 2) from both groups were also salvaged by suture ligation. CONCLUSIONS: Suture ligation with cauterization for an internal orifice of branchial anomaly showed lower recurrence rate than cauterization only. This method was beneficial for refractory cases.

OBJECTIVES: Injection laryngoplasty (IL) is performed to reduce the gap between vocal folds induced by unilateral vocal fold paralysis (UVFP). Voice quality after IL may be different due to other factors that influence voice quality. Voice therapy has been reported to improve voice quality after IL in patients with UVFP. This study evaluated the efficacy of voice therapy combined with IL. METHODS: Patients with UVFP who underwent IL as primary therapy from March 2017 to June 2019 were evaluated. The enrolled patients were divided into two groups, those who did and did not receive voice therapy after IL. Voice quality was evaluated using perceptual, acoustic, and aerodynamic parameters, and voice handicap index-30 scores one month after IL and after completing each treatment. RESULTS: Of 261 patients who underwent IL during the study period, 40 were enrolled, including 21 who did and 19 who did not receive voice therapy. Voice parameters one month after IL did not differ between these two groups. Jitter, shimmer, noise-to-harmonic ratio, and mean flow rate decreased, while maximum phonation time increased after voice therapy (both P < 0.05). In the absence of voice therapy, improved voice parameters were maintained for six months after IL. Total voice handicap index-30 scores decreased, from 35.6 to 19.1 (P < 0.05), in patients who received voice therapy. CONCLUSION: Voice therapy following IL is beneficial to patients with UVFP. Combined treatment can help to maintain improved voice quality more than six months after IL.

BACKGROUND: Thyroid lobectomy is recommended as the primary treatment for low-risk thyroid cancer. However, recurrence and hypothyroidism may develop after lobectomy, necessitating thyroid hormone supplementation. The 2015 American Thyroid Association (ATA) guidelines recommended post-lobectomy thyroid-stimulating hormone (TSH) suppression. This study examined the need for TSH suppression and recurrence after lobectomy for unilateral papillary thyroid carcinoma (PTC). METHODS: This study involved 369 patients who underwent thyroid lobectomy and ipsilateral central neck dissection for PTC between 2007 and 2015. Thyroid function tests were performed before and regularly after lobectomy. Binary logistic regression analyses were used to find factors predictive of the post-lobectomy need for TSH suppression that was defined by the 2015 ATA guidelines. RESULTS: Serum TSH concentrations gradually increased after lobectomy: proportions with TSH >2 mIU/L at post-lobectomy 1, 3-6, 12, and 24 months were found in 77.0%, 82.3%, 66.7%, and 59.9%, respectively. After lobectomy, 168 (45.5%) patients received levothyroxine (T4) supplementation. Multivariate logistic regression analyses showed that pre-TSH level >2 mIU/L was the sole independent variable predictive of the need for post-lobectomy TSH suppression (P = 0.003). During the median follow-up of 72 months, recurrence was found in 4 (1.1%) patients who never received T4 supplementation and had post-lobectomy TSH levels >2 mIU/L. CONCLUSIONS: Our data show that thyroid lobectomy for unilateral PTC is associated with a low recurrence rate, but a significant risk of hypothyroidism. Preoperative TSH level can predict the need for post-lobectomy TSH suppression compliant with the 2015 ATA guidelines.

OBJECTIVES/HYPOTHESIS: There may be an interobserver variation in the diagnosis of laryngeal disease based on laryngoscopic images according to clinical experience. Therefore, this study is aimed to perform computer-assisted diagnosis for common laryngeal diseases using deep learning-based disease classification models. STUDY DESIGN: Experimental study with retrospective data METHODS: A total of 4106 images (cysts, nodules, polyps, leukoplakia, papillomas, Reinke's edema, granulomas, palsies, and normal cases) were analyzed. After equal distribution of diseases into ninefolds, stratified eightfold cross-validation was performed for training, validation process and remaining onefold was used as a test dataset. A trained model was applied to test sets, and model performance was assessed for precision (positive predictive value), recall (sensitivity), accuracy, F1 score, precision-recall (PR) curve, and PR-area under the receiver operating characteristic curve (PR-AUC). Outcomes were compared to those of visual assessments by four trainees. RESULTS: The trained deep neural networks (DNNs) outperformed trainees' visual assessments in discriminating cysts, granulomas, nodules, normal cases, palsies, papillomas, and polyps according to the PR-AUC and F1 score. The lowest F1 score and PR-AUC of DNNs were estimated for Reinke's edema (0.720, 0.800) and nodules (0.730, 0.780) but were comparable to the mean of the two trainees' F1 score with the best performances (0.765 and 0.675, respectively). In discriminating papillomas, the F1 score was much higher for DNNs (0.870) than for trainees (0.685). Overall, DNNs outperformed all trainees (micro-average PR-AUC = 0.95; macro-average PR-AUC = 0.91). CONCLUSIONS: DNN technology could be applied to laryngoscopy to supplement clinical assessment of examiners by providing additional diagnostic clues and having a role as a reference of diagnosis. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:2558-2566, 2021.

ABSTRACT: Although the incidence of oral cavity cancer (OCC) in young never smoker females is increasing worldwide, there has been little research on the etiologies and characteristics of these patients to date. In this study, we sought to evaluate the annual increase in OCC incidence in young never smoker females (YNSF) in our hospital as well as to investigate their clinicopathological characteristics and different disease courses compared with those of other OCC patients. We retrospectively reviewed the medical records of patients who were diagnosed and treated at our tertiary referral hospital from 2006 to 2016. The annual incidence of OCC and proportion of YNSF (never smoker females aged 45 years or younger at the time of diagnosis) among the enrolled OCC patients were evaluated. The characteristics and prognosis of the YNSF group were analyzed using their clinicopathological and survival data. Among the OCC patients primarily enrolled in this study, the proportion of YNSF did not show significant annual increase. There were 32 YNSF among 354 OCC patients (9%), who were ultimately included for the analyses of clinicopathological characteristics and survival. However, YNSF showed no significant differences compared with other OCC patients, even in subgroup analyses for overall survival. Our study did not demonstrate significant changes in the annual proportion of YNSF among OCC patients. In addition, differences in neither clinicopathological characteristics nor survival were noted between YNSF and other OCC patients.

INTRODUCTION: Sarcopenia may result in negative outcomes in patients with cancer, but its impact on surgical and oncological outcomes in older adult patients with head and neck squamous cell carcinoma (HNSCC) has not been systematically studied. This study evaluated the clinical impact of sarcopenia on postsurgical and oncological outcomes in older adult patients with HNSCC. METHODS: This is a prospective study of 190 consecutive HNSCC patients aged ≥65 years who underwent curative surgery at a tertiary referral hospital. Sarcopenia was determined from measurement of the cross-sectional area of skeletal muscles at the level of the third lumbar vertebra on pretreatment images of whole body 18F-fluorodeoxyglucose positron emission tomography/computed tomography. Primary outcomes were early complications and overall survival. Factors of early complications and readmission were identified using binary logistic regression analyses, and factors of overall survival and disease-free survival were identified using univariate and multivariate Cox proportional hazards regression analyses. RESULTS: Pretreatment sarcopenia were found in 64 (33.7%) patients. In multivariate analysis, sarcopenia and N classification were significantly associated with early complications, while sarcopenia and T classification were associated with readmission. Independent factors of overall survival outcomes were age, sarcopenia, and extranodal extension (all P < .005). Sarcopenia was also an independent factor predictive of disease-free survival outcome (P < .001). Sarcopenia was associated with a 3.2-fold increase in the early complication rate and 4.5-fold increase in mortality in older adult surgical patients with HNSCC. CONCLUSION: Sarcopenia may predict early complications and survival after curative surgery in older adult patients with HNSCC.

BACKGROUND: Primary squamous cell carcinoma (SCC) of the salivary gland is a rare disease, and distinguishing primary SCC from metastatic SCC is difficult. This study investigated the histological and immunohistochemical differences between primary and metastatic salivary gland SCC to improve the accuracy of diagnosis and to explore the pathogenesis of this disease. METHODS: Data of 16 patients who underwent surgery for SCC of salivary glands between 2000 and 2018 at Asan Medical Center were retrieved. Eight patients had a history of SCC at other sites, and eight patients had only salivary gland SCC. Immunostaining for p16, p53, androgen receptor (AR), gross cystic disease fluid protein 15 (GCDFP-15), and c-erbB2, as well as mucicarmine staining, were compared between the two groups. RESULTS: Most tumors were located in the center of the salivary glands with extraparenchymal extension. The histology of primary SCC of the salivary gland was consistent with moderately differentiated SCC with extensive desmoplastic reaction and peritumoral inflammation. Involvement of the salivary gland ducts and transition into the ductal epithelium were observed in two cases. Metastatic SCC resembled the primary tumor histologically and was associated with central necrosis. Both groups exhibited negative mucin staining. Two, one, and one primary SCC case exhibited AR, GCDFP-15, and c-erbB2 positivity, respectively. CONCLUSIONS: A subset of primary SCCs originated in salivary ducts or was related to salivary duct carcinoma. Distinguishing primary from metastatic SCC of the salivary gland is difficult using histologic features and immunoprofiles. A comprehensive review of the medical history is essential.
RESUMO
PURPOSE: Oral cavity squamous cell carcinoma (OCC) can spread to the neck without apparent lymphadenopathy. Pretreatment detection or prediction of occult metastasis might contribute to proper management of clinically node-negative (cN0) OCC. We examined the role of tumour quantitative 18-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) measurements for predicting OCC occult metastasis and survival. METHODS: This study included 130 cN0 OCC patients who underwent 18F-FDG PET/CT scanning and subsequent curative surgery and neck dissection. Maximum, peak, and mean standardized uptake value (SUVmax, SUVpeak, and SUVmean), metabolic tumour volume (MTV), and total lesion glycolysis (TLG) were measured on pretreatment 18F-FDG PET/CT. Binary logistic regression was used to identify factors predicting occult cervical metastasis. Univariate and multivariate Cox proportional hazard regression were used to find factors associated with overall survival (OS). RESULTS: Pathological cervical metastasis (pN +) was found in 29 (22.3%) patients. Age, tumour differentiation, lymphovascular invasion, and T classification were significantly associated with pN + (all P < 0.05). After adjustment for these factors, MTV and TLG independently predicted pN + (P < 0.05). Invasion depth, lymphovascular invasion, T and N classifications, and overall TNM stage were significantly associated with OS. After adjustment for these factors, SUVmax and TLG independently predicted OS (all P < 0.05). Patients with TLG > 9.3 g had a 5.7-fold increased risk of overall mortality.

BACKGROUND: American Thyroid Association (ATA) proposed management guidelines for differentiated thyroid cancer, including a three-tiered risk stratification system for structural recurrence. This study aimed to compare the various 2015 ATA criteria for the strength of association with the recurrence of high-risk papillary thyroid carcinoma (PTC). STUDY DESIGN: This study included 545 consecutive patients who underwent total thyroidectomy plus neck dissection and radioactive iodine ablation (RAI) for previously untreated high-risk PTC. The association of recurrence-free survival (RFS) with clinicopathological factors was evaluated by univariate and multivariate Cox proportional hazard regression analyses. RESULTS: During a follow-up median period of 89 months, 90 (16.5%) patients had any-site recurrence. Of the high-risk factors, high stimulated thyroglobulin (sTg) level and >3-cm sized lymph nodes (LNs) were significantly associated with recurrence (all P < .005). Sex, tumor size, lymphovascular invasion, multifocality, number of positive LNs, extranodal extension, T and N classifications, and overall tumor-node-metastasis stage were also significantly associated with recurrence (all P < .05). In multivariate analyses, high sTg level [adjusted hazard ratio (HR) = 7.18] and N1b (adjusted HR = 3.27) were independent factors predictive of recurrence (all P ≤ .001). CONCLUSIONS: Postoperative high serum sTg level might be the most important predictor of PTC recurrence after total thyroidectomy plus neck dissection and RAI.

OBJECTIVES: Pre- and post-treatment 18F-FDG PET/CT may have a prognostic role in human cancers. 18F-FDG PET/CT after primary surgery for head and neck cancer might also predict survival. Therefore, we evaluated the prognostic value of post-treatment 18F-FDG PET/CT in primary surgical patients with advanced-stage head and neck squamous cell carcinoma (HNSCC). MATERIALS AND METHODS: This prospective study involved 225 patients with previously untreated advanced-stage HNSCC who underwent primary surgery with or without postoperative radiotherapy or chemoradiotherapy. The patients also had 18F-FDG PET/CT scanning at a median 6 months after surgery. Post-treatment 18F-FDG PET/CT was considered positive, based on interpretation by experienced nuclear medicine physicians with integrating clinical information. Positive and negative predictive values (PPV and NPV) for positive 18F-FDG PET/CT in association with recurrence were calculated. Predictors for positive post-treatment 18F-FDG PET/CT were evaluated using binary logistic regression. Survival analysis was performed using Cox proportional hazard regression analysis. RESULTS: PPV and NPV for post-treatment PET/CT for overall recurrence were 75.8% and 98.7%, respectively. A positive post-treatment PET/CT was an independent predictive factor for overall and disease-free survival (both P < 0.001). Five-year overall survival rates for patients with positive and negative PET/CT were 48.1% and 92.3%, respectively. Corresponding 5-year disease-free survival rates were 22.5% and 82.4%, respectively. Perineural invasion, positive resection margin, positive pathological node, and extranodal extension were the independent predictors of positive 18F-FDG PET/CT (all P < 0.05). CONCLUSIONS: Post-treatment 18F-FDG PET/CT predicts survival and recurrence in patients undergoing curative surgery for advanced-stage HNSCC.

OBJECTIVES: Soft tissue sarcomas of the head and neck (HNSTS) show various histological types and clinical behaviour. Recently, the 8th edition of the American Joint Committee on Cancer (AJCC) proposed a staging system for HNSTS independent of other body soft tissue sarcomas, which requires validation. Therefore, we evaluated the prognostic factors for the survival of HNSTS patients through a comparison between previous and current AJCC staging systems. MATERIALS AND METHODS: This study involved 135 consecutive HNSTS patients who underwent primary surgery, chemoradiotherapy or chemotherapy. Patients were grouped into staged (S) and not staged (NS) cancer according to the AJCC 8th edition staging. Cox proportional-hazard regression analyses were used to identify factors associated with overall survival (OS), and progression-free survival (PFS) in all, S or NS patients. RESULTS: Median follow-up period was 75 months and the 5-year OS and PFS rates of all patients were 67.8% and 53.4%, respectively, which was similar between S and NS groups. Age, tumour size and grade, overall stage (7th edition) and resection margin were the significant prognostic factors for OS and PFS in all patients and NS group (all P < 0.05), whereas positive resection margin was the only significant factor for OS and PFS in the S group (P < 0.001). While OS was poorly discriminated among different 8th edition T-categories, different 7th edition showed good discrimination among overall stages in all patients and the NS group. CONCLUSION: The revised staging system may not provide an improved risk stratification for survival of HNSTS patients.
