RESUMO

Head and neck squamous cell carcinoma (HNSCC) tumor phenotypes and clinical outcomes are significantly influenced by etiological agents, such as HPV infection, smoking, and alcohol consumption. Accordingly, the intratumor microbiome has been increasingly implicated in cancer progression and metastasis. However, few studies characterize the intratumor microbial landscape of HNSCC with respect to these etiological agents. In this study, we aimed to investigate the bacterial and fungal landscape of HNSCC in association with HPV infection, smoking, and alcohol consumption. RNA-sequencing data were extracted from The Cancer Genome Atlas (TCGA) regarding 449 tissue samples and 44 normal samples. Pathoscope 2.0 was used to extract the microbial reads. Microbe abundance was compared to clinical variables, oncogenic signatures, and immune-associated pathways. Our results demonstrated that a similar number of dysregulated microbes was overabundant in smokers and nonsmokers, while heavy drinkers were characterized by an underabundance of dysregulated microbes. Conversely, the majority of dysregulated microbes were overabundant in HPV+ tumor samples when compared to HPV- tumor samples. Moreover, we observed that many dysregulated microbes were associated with oncogenic and metastatic pathways, suggesting their roles in influencing carcinogenesis. These microbes provide insights regarding potential mechanisms for tumor pathogenesis and progression with respect to the three etiological agents.

RESUMO

Smoking and HPV infection are known causes for the vast majority of head and neck squamous cell carcinomas (HNSCC) due to their likelihood of causing gene dysregulation and genomic alterations. Enhancer RNAs (eRNAs) are non-coding RNAs that are known to increase nearby and target gene expression, and activity that has been suggested to be affected by genetic and epigenetic alterations. Here we sought to identify the effects of smoking and HPV status on eRNA expression in HNSCC tumors. We focused on four patient cohorts including smoking/HPV+, smoking/HPV-, non-smoking/HPV+, and non-smoking/HPV- patients. We used TCGA RNA-seq data from cancer tumors and adjacent normal tissue, extracted eRNA read counts, and correlated these to survival, clinical variables, immune infiltration, cancer pathways, and genomic alterations. We found a large number of differentially expressed eRNA in each patient cohort. We also found several dysregulated eRNA correlated to patient survival, clinical variables, immune pathways, and genomic alterations. Additionally, we were able to find dysregulated eRNA nearby seven key HNSCC-related oncogenes. For example, we found eRNA chr14:103272042-103272430 (eRNA-24036), which is located close to the TRAF3 gene to be differentially expressed and correlated with the pathologic N stage and immune cell populations. Using a separate validation dataset, we performed differential expression and immune infiltration analysis to validate our results from the TCGA data. Our findings may explain the association between eRNA expression, enhancer activity, and nearby gene dysregulation.

RESUMO

Head and neck squamous cell carcinoma persists as one of the most common and deadly malignancies, with early detection and effective treatment still posing formidable challenges. To expand our currently sparse knowledge of the noncoding alterations involved in the disease and identify potential biomarkers and therapeutic targets, we globally profiled the dysregulation of small nucleolar and long noncoding RNAs in head and neck tumors. Using next-generation RNA-sequencing data from 40 pairs of tumor and matched normal tissues, we found 2808 long noncoding RNA (lncRNA) transcripts significantly differentially expressed by a fold change magnitude ≥2. Meanwhile, RNA-sequencing analysis of 31 tumor-normal pairs yielded 33 significantly dysregulated small nucleolar RNAs (snoRNA). In particular, we identified two dramatically down-regulated lncRNAs and one down-regulated snoRNA whose expression levels correlated significantly with overall patient survival, suggesting their functional significance and clinical relevance in head and neck cancer pathogenesis. We confirmed the dysregulation of these noncoding RNAs in head and neck cancer cell lines derived from different anatomic sites, and determined that ectopic expression of the two lncRNAs inhibited key EMT and stem cell genes and reduced cellular proliferation and migration. As a whole, noncoding RNAs are pervasively dysregulated in head and squamous cell carcinoma. The precise molecular roles of the three transcripts identified warrants further characterization, but our data suggest that they are likely to play substantial roles in head and neck cancer pathogenesis and are significantly associated with patient survival.

RESUMO

BACKGROUND: [(99m)Tc]Tilmanocept, a novel CD206 receptor-targeted radiopharmaceutical, was evaluated in an open-label, phase III trial to determine the false negative rate (FNR) of sentinel lymph node biopsy (SLNB) relative to the pathologic nodal status in patients with intraoral or cutaneous head and neck squamous cell carcinoma (HNSCC) undergoing tumor resection, SLNB, and planned elective neck dissection (END). Negative predictive value (NPV), overall accuracy of SLNB, and the impact of radiopharmaceutical injection timing relative to surgery were assessed. METHODS AND FINDINGS: This multicenter, non-randomized, single-arm trial (ClinicalTrials.gov identifier NCT00911326) enrolled 101 patients with T1-T4, N0, and M0 HNSCC. Patients received 50 µg [(99m)Tc]tilmanocept radiolabeled with either 0.5 mCi (same day) or 2.0 mCi (next day), followed by lymphoscintigraphy, SLNB, and END. All excised tissues were evaluated for tissue type and tumor presence. [(99m)Tc]Tilmanocept identified one or more SLNs in 81 of 83 patients (97.6 %). Of 39 patients identified with any tumor-positive nodes (SLN or non-SLN), one patient had a single tumor-positive non-SLN in whom all SLNs were tumor-negative, yielding an FNR of 2.56 %; NPV was 97.8 % and overall accuracy was 98.8 %. No significant differences were observed between same-day and next-day procedures. CONCLUSIONS: Use of receptor-targeted [(99m)Tc]tilmanocept for lymphatic mapping allows for a high rate of SLN identification in patients with intraoral and cutaneous HNSCC. SLNB employing [(99m)Tc]tilmanocept accurately predicts the pathologic nodal status of intraoral HNSCC patients with low FNR, high NPV, and high overall accuracy. The use of [(99m)Tc]tilmanocept for SLNB in select patients may be appropriate and may obviate the need to perform more extensive procedures such as END.

RESUMO

Head and Neck Squamous Cell Carcinoma (HNSCC) is a highly heterogeneous cancer that is characterized by distinct phenotypes based on anatomical site and etiological agents. Recently, the intratumor microbiome has been implicated in cancer pathogenesis and progression. Although it is well established that the gut microbiome varies with geographical location and is highly influenced by factors such as diet, environment, and genetics, the intratumor microbiome is not very well characterized. In this review, we aim to characterize the HNSCC intratumor microbiome by geographical location and anatomical site. We conducted a review of primary literature from PubMed and assessed studies based on relevancy and recency. To the best of our knowledge, we are the first to comprehensively examine the tumor microenvironment of HNSCC with respect to these two primary factors on a large scale. Our results suggest that there are unique bacterial and fungal biomarkers for HNSCC for each of the following geographical locations: North America, Asia, Europe, Australia, and Africa. We also identified a panel of microbial biomarkers that are unique to two primary HNSCC anatomic sites, as well as microbial biomarkers associated with various etiological agents of HNSCC. Future study of these microbes may improve HNSCC diagnostic and therapeutic modalities by accounting for differences based on geographic regions and anatomical sites.

RESUMO

A 42-year-old man presented with right-sided epiphora, a fleshy lesion emanating from the right inferior punctum and a painless mass below the medial canthal tendon. Biopsy of the lacrimal sac mass disclosed papillary squamous cell carcinoma in situ. The patient underwent wide local excision with clear surgical margins and remained disease free until 28 months later when he returned with hemorrhagic epiphora of the OS and fullness overlying the left lacrimal sac. Biopsy confirmed papillary squamous cell carcinoma in situ. He underwent similar excision and has remained disease free for 6 months. To the best of the authors' knowledge, this is the first report of bilateral squamous cell carcinoma of the lacrimal sac.

RESUMO

BACKGROUND: The use of ultrasound-guided ablation procedures to treat both benign and malignant thyroid conditions is gaining increasing interest. This document has been developed as an international interdisciplinary evidence-based statement with a primary focus on radiofrequency ablation and is intended to serve as a manual for best practice application of ablation technologies. METHODS: A comprehensive literature review was conducted to guide statement development and generation of best practice recommendations. Modified Delphi method was applied to assess whether statements met consensus among the entire author panel. RESULTS: A review of the current state of ultrasound-guided ablation procedures for the treatment of benign and malignant thyroid conditions is presented. Eighteen best practice recommendations in topic areas of preprocedural evaluation, technique, postprocedural management, efficacy, potential complications, and implementation are provided. CONCLUSIONS: As ultrasound-guided ablation procedures are increasingly utilized in benign and malignant thyroid disease, evidence-based and thoughtful application of best practices is warranted.

RESUMO

BACKGROUND: Primary hyperparathyroidism is a biochemical, not radiologic diagnosis. Parathyroid scintigraphy should only be requested for surgical planning, not to confirm diagnosis. Here we determined reasons for inappropriately ordered parathyroid scintigraphy. METHODS: We generated a database of patients undergoing parathyroid scintigraphy over 5 years, who did not undergo parathyroidectomy. RESULTS: Over 5 years 129 parathyroid scintigraphies (of 308 total scans) were performed in patients who did not undergo parathyroidectomy. We determined that only 58 (45%) had true primary hyperparathyroidism. The most common reason for the scan was to "confirm the diagnosis." Only 20% were ordered for adenoma localization, although surgery was not performed. Physicians requesting parathyroid scintigraphies specialized in a variety of disciplines. CONCLUSION: Forty-two percent of parathyroid scintigraphies were requested inappropriately to "confirm" a diagnosis of primary hyperparathyroidism. We propose to change the ordering system to clarify that parathyroid scintigraphy is a functional tool to optimize surgery when the diagnosis is secure.

RESUMO

OBJECTIVE: Posterior neck masses are a relatively poorly characterized entity. The authors attempt to further characterize the anatomy and pathology of the posterior neck by way of a combined single-institution retrospective chart review and systematic review of the literature. METHODS: A single-institution retrospective chart review was undertaken for all patients undergoing excision of a posterior neck mass between January 1, 2012, and January 1, 2017. A systematic review of the Medline, Embase, Web of Science, and Cochrane database was undertaken in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in search of case reports and series describing posterior neck masses. RESULTS: A total of 28 patients who underwent excision of a posterior neck mass were encountered during the retrospective chart review. All pathologies were benign, the most prevalent of which was lipoma (22/28, 79%). A total of 19 articles describing a collective 36 posterior neck masses were encountered during the systematic review. Lipomas were the most common pathology (15/36, 42%). All but one of the masses reported were benign (35/36, 97%). CONCLUSIONS: Patients presenting with posterior neck masses can be reassured of a low risk of malignancy. The majority of posterior neck masses can be appropriately evaluated via physical examination and ultrasound.

RESUMO

BACKGROUND: Hypopharyngeal cancer is associated with poor survival. Robotic surgery is emerging as a treatment for hypopharyngeal tumors, but no rigorous data are available to assess its effect on survival. METHODS: The National Cancer Database (NCDB) was used to identify patients with T1 and T2 hypopharyngeal tumors undergoing robotic surgery, laser surgery, and primary radiation with or without chemotherapy from 2010 to 2016. All adult patients with available staging and no distant metastasis were included. RESULTS: We compared 57 patients undergoing robotic surgery, 236 undergoing laser surgery, and 5,742 undergoing primary radiation. Compared to laser surgery, patients undergoing robotic surgery were significantly more likely to have negative margins, neck dissection, lower incomes, and care at an academic center. Rates of robotic surgery also significantly increased from 2010 to 2015. After multivariate regression, robotic surgery was associated with significantly improved overall survival compared to laser surgery and primary radiation. CONCLUSION: Robotic surgery improves overall survival for T1 and T2 hypopharyngeal tumors compared to laser surgery and primary radiation in this NCDB cohort. This effect may be mediated by decreased positive margin rates relative to laser surgery. Rates of hypopharyngeal robotic surgery are expected to increase with wider adoption of robotic platforms and may improve overall survival rates for hypopharyngeal cancer.

RESUMO

BACKGROUND: Pulmonary Langerhans cell histiocytosis (PLCH) is usually confined to the lungs and is therefore an unexpected finding in a cervical lymph node. CASE: A 52-year-old male with a 40-pack-year smoking history presented to our clinic with cough, fever and cervical lymphadenopathy. Chest computed tomography (CT) showed bilateral pulmonary nodules and enlarged mediastinal lymph nodes, worrisome for an infectious or malignant process. Bronchioloalveolar lavage was nondiagnostic. Fine needle aspiration cytology of the enlarged cervical lymph node revealed atypical histiocytoid cells, suspicious for malignancy. Immunohistochemistry revealed CD1a- and S-100-positive Langerhans cells. These findings, along with the patient's extensive smoking history and characteristic radiographic nodules, favored a diagnosis of PLCH with cervical lymph node involvement. The patient was advised to cease smoking, and no therapy was administered. Months later, follow-up chest CT showed spontaneous resolution of the lung nodules. CONCLUSION: The demonstration of Langerhans cells by immunohistochemical staining of CD1a and S-100 on a fine needle aspiration cell block is a useful diagnostic adjunct. In this case, definitive cytology for Langerhans cells in the appropriate clinical and radiologic setting allowed us to arrive at the correct diagnosis of PLCH in a minimally invasive manner.

RESUMO

BACKGROUND: Recurrent head and neck squamous cell carcinoma (HNSCC) after radiation is associated with poor survival, and management of the clinically negative (N0) neck during salvage surgery is controversial. METHODS: Studies were selected according to preferred reporting items for systematic reviews and meta-analyses guidelines. Inclusion criteria were patients with HNSCC, prior radiation to the lateral neck nodal basin, undergoing salvage surgery for local recurrence, persistence or second primary, and N0 at time of salvage. Eleven studies with a total of 382 patients met inclusion criteria. RESULTS: The rate of occult metastasis was 15.4%. The pooled rate of occult nodal metastasis was 16.2% for oral cavity, 12.9% for oropharynx, 23.7% for hypopharynx, and 27.3% for supraglottic or transglottic tumors. There was a significantly higher relative risk of occult metastasis for locally advanced tumors. CONCLUSION: Elective neck dissection at time of salvage surgery should be considered based on subsite, T classification, and prior history of nodal metastasis.

RESUMO

OBJECTIVES:: To report a case of total facial paralysis as the result of a core needle biopsy. METHODS:: Case report and literature review. RESULTS:: A 70-year-old man was diagnosed with a deep lobe parotid tumor on computed tomography. During a core needle biopsy, he developed complete facial paralysis. The cause was discovered to be a direct stab injury to the main trunk of the facial nerve. CONCLUSIONS:: When biopsying parotid lesions adjacent to the main trunk of the facial nerve, the use of smaller-gauge needles and additional patient counseling should be considered.

RESUMO

Importance: Despite the ease of preoperative anemia diagnosis and the availability of treatment options, the morbidity and mortality associated with this condition remain unacceptably high, and the literature describing the association of preoperative anemia with postoperative outcomes following thyroid surgery in patients with thyroid cancer remain sparse. Reporting outcomes in this patient population may help to facilitate preoperative optimization. Objective: To assess whether an association exists between preoperative anemia and outcomes following thyroid surgery in patients with thyroid cancer. Design, Setting, and Participants: This retrospective, cross-sectional, cohort study used the American College of Surgeons National Surgical Quality Improvement Program database to identify 32 166 patients between 2007 and 2016 with Current Procedural Terminology codes for thyroid surgery and with the International Classification of Diseases, Ninth Revision code of malignant thyroid cancer. Exposures: Preoperative anemia as defined using the World Health Organization criteria of hematocrit less than 36% in nonpregnant females and less than 39% in males. Main Outcomes and Measures: Multivariable logistic regression analysis was conducted to assess the association of preoperative anemia with the following 30-day postoperative outcomes: pulmonary, infectious, and cardiac complications, overall and serious morbidity (surgical site infection and medical complications), prolonged hospital length of stay (≥75th percentile for the cohort), and mortality. Results: Among the 24 912 patients with thyroid cancer who underwent thyroidectomy included in the final analysis, the median (interquartile range) age was 51 (40-62) years and the majority were women (18 705 [75.1%]). The prevalence of preoperative anemia was 12.5% (n = 3108). Within the overall study population, hypertension (9242 patients [37.1%]) followed by active smoking (2992 patients [12.0%]) were the most prevalent comorbidities. The unadjusted odds of anemia vs no anemia were significantly higher for every 10-year increase in age (odds ratio [OR], 1.10; 95% CI, 1.08-1.13) and for black vs white patients (OR, 2.82; 95% CI, 2.51-3.17). The adjusted odds of postoperative overall morbidity (OR, 1.68; 95% CI, 1.29-2.17), mortality (OR, 3.36; 95% CI, 1.37-8.28), and pulmonary (OR, 2.36; 95% CI, 1.65-3.34) and infectious (OR, 1.62; 95% CI, 1.12-2.29) complications were higher in patients with preoperative anemia than in those without preoperative anemia. Conclusions and Relevance: The findings from this study suggest that preoperative anemia may not only be associated with racial differences and a higher comorbidity burden but may also increase the likelihood of postoperative morbidity and mortality. These results may provide a basis for further risk reduction strategies and preoperative optimization.

RESUMO

Up to 20% of abnormal parathyroid glands causing primary or secondary hyperparathyroidism are located ectopically. Of these, approximately 1%-2% reside in the mediastinum and may not always be resectable through a traditional cervical approach. Recently, video-assisted thoracoscopic surgery (VATS) has arisen as a minimally invasive method for resecting mediastinal parathyroid glands and avoiding the complications and higher morbidity of a sternotomy. In this paper, we present a case of a patient with asymptomatic hyperparathyroidism and an ectopic parathyroid on sestamibi imaging in the mediastinum. Initially, the patient underwent a bilateral cervical exploration, left upper parathyroidectomy, and partial thymectomy; however, postoperatively, he continued to have persistently elevated serum calcium and parathyroid hormone levels. Ultimately, management consisted of parathyroidectomy through a VATS approach, along with intraoperative parathyroid assay monitoring and frozen-section pathologic analysis. The patient was successfully discharged to home several hours after surgery. To our knowledge, this is the first reported case of mediastinal ectopic parathyroid adenoma treated with outpatient VATS.

RESUMO

BACKGROUND: Our aim was to evaluate the ease and utility of using indocyanine green fluorescence angiography for intraoperative localization of the parathyroid glands. METHODS: Indocyanine green fluorescence angiography was performed during 60 parathyroidectomies for primary hyperparathyroidism during a 22-month period. Indocyanine green was administered intravenously to guide operative navigation using a commercially available fluorescence imaging system. Video files were graded by 3 independent surgeons for strength of enhancement using an adapted numeric scoring system. RESULTS: There were 46 (77%) female patients and 14 (23%) male patients whose ages ranged from 17 to 87 (average 60) years old. Of the 60 patients, 43 (71.6%) showed strong enhancement, 13 (21.7%) demonstrated mild to moderate vascular enhancement, and 4 (6.7%) exhibited little or no vascular enhancement. Of the 54 patients who had a preoperative sestamibi scan, a parathyroid adenoma was identified in 36, while 18 failed to localize. Of the 18 patients who failed to localize, all 18 patients (100%) had an adenoma that fluoresced on indocyanine green imaging. The operations were performed safely with minimal blood loss and short operative times. CONCLUSION: Indocyanine green angiography has the potential to assist surgeons in identifying parathyroid glands rapidly with minimal risk.

RESUMO

BACKGROUND: Fine-needle biopsy is the international standard for diagnostic evaluation of thyroid nodules. There is a lack of consensus regarding the optimal needle biopsy technique. The implementation of capillary action versus aspiration and the optimal needle gauge remain topics of debate. METHODS: A systematic review of the Medline, Embase, and Cochrane databases was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles evaluating the effects of capillary action versus aspiration and needle gauge on success rates of fine-needle biopsy of the thyroid were assessed for inclusion. The primary outcome of interest was the rate of non-diagnostic cytopathology. RESULTS: Twenty-four articles with a collective 4428 nodules were ultimately included in the review. Twenty articles evaluated capillary action versus aspiration, and six evaluated needle gauge. All but two studies were prospective, most of which were blinded trials with or without randomization. Using a random-effects model, capillary action was associated with a statistically significant reduction in the relative risk of non-diagnostic cytopathology (relative risk = 0.57 [confidence interval 0.34-0.92]; p = 0.02). There was a nonsignificant trend in favor of smaller needle gauges. CONCLUSION: Given the statistically significant deceased rate of non-diagnostic cytopathology with capillary action and the potential for increased pain and complications with larger needles without a proven benefit, needle biopsy of routine thyroid nodules should be performed without aspiration and with smaller needle gauges (24-27G).

RESUMO

OBJECTIVE: To characterize the safety profile and effectiveness of esophageal dilation in head and neck cancer patients. METHODS: A systematic review was undertaken for articles reporting outcomes of esophageal dilation in head and neck cancer patients. The Medline, Scopus, Web of Science, and Cochrane databases were searched in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Complications related to esophageal dilation in head and neck cancer patients was the primary outcome of interest. Success rates, demographic data, cancer staging, and treatment data were assessed secondarily. Statistical analyses included both qualitative and quantitative assessments. A limited meta-analysis and pooling of the data was performed using a random effects model. RESULTS: Of the collective 8,243 initial candidate articles, 15 retrospective studies containing data for a collective 449 patients were ultimately included in the analysis. There was significant heterogeneity in the outcomes data. With an overall complication rate of 10.6% (95% confidence interval [CI]: 4.1%,17%) and a pooled success rate of 72.9% (95% CI: 65.7%,80.1%) per patient, the articles generally supported the use of dilation. CONCLUSION: Head and neck cancer patients experience a higher rate of complications following dilation compared to patients with other causes of benign stricture. Esophageal dilation is effective in improving dysphagia, but these benefits are often transient and thus necessitate repeat interventions. Laryngoscope, 128:111-117, 2018.

RESUMO

OBJECTIVES: Opioids have been overprescribed after general and orthopedic surgeries, but prescribing patterns have not been reported for head and neck surgery. The objectives of this retrospective review are to describe postoperative opioid prescriptions after oral cancer surgery and determine which patients receive higher amounts. METHODS: A single institution retrospective review was performed for 81 adults with oral cavity tumors undergoing surgery. Opioid prescriptions upon discharge were reported in daily oral morphine equivalents (OME). High opioids were defined as > 90 mg daily and > 200 mg total, commensurate with U.S. Center for Disease Control and Prevention and state guidelines. Multivariable logistic regression was performed to investigate factors associated with high opioids. RESULTS: The median number of doses dispensed was 30 (interquartile range [IQR] 30-45; range 3-120). The median daily dose was 30 mg (IQR 20-45 mg; range 15-240 mg). Five patients (6%) received higher than the recommended daily dose. The median total dispensed amount was 225 mg (IQR 150-250 mg; range 15-1200 mg). Fifty-one (63%) received greater than the recommended total dose. On multivariable logistic regression, advanced tumor stage (odds ratio [OR] 11.5; 95% confidence interval [CI] 1.2-109.4; P = 0.034) and inpatient pain scores (OR 1.3 per 1-unit increase; 95% CI 1.0-1.7; P = 0.039) were associated with receiving high total opioids after surgery. CONCLUSION: The majority of patients received greater than the recommended 200 mg total OME. Advanced stage and higher inpatient pain scores were associated with receiving more opioids for discharge. Consensus-driven analgesic plans are needed to reduce excess opioids after discharge following head and neck surgery. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:2361-2366, 2018.
