Sinonasal undifferentiated carcinoma (SNUC) is a rapidly growing malignancy with a propensity for extensive local invasion. Multimodal therapy, including surgery, radiotherapy, and chemotherapy, is the standard approach to treatment, but the optimal sequence and combination of these modalities are uncertain. Induction chemotherapy is being increasingly utilized based on recent reports that show better outcomes for patients who respond to chemotherapy and the ability to determine further course of treatment. We present a unique case of a patient with locally advanced SNUC that did not respond to induction chemotherapy and a review of the available literature relating to the management of this rare malignancy.

Objective/UNASSIGNED:Previous studies have questioned the safety and efficacy of minor salivary gland biopsy in the diagnosis of Sjögren's syndrome, citing complications and difficulty of pathologic evaluation. This study aims to determine the rate of biopsy specimen adequacy and the risk of complications after minor salivary gland biopsy. Study Design/UNASSIGNED:Case series. Setting/UNASSIGNED:Single tertiary care center. Methods/UNASSIGNED:sample were considered positive. Results/UNASSIGNED:We identified 110 patients who underwent minor salivary gland biopsy. Ninety-three (85%) were female, and the median age was 49.1 years (range, 18.7-80.5). Seventy-seven procedures (70%) were performed in the office setting, and 33 (30%) were performed in the operating room. Nearly all biopsy samples (n = 108, 98%) were adequate, and 33 (31%) were interpreted as positive. Four patients (4%) experienced temporary lip numbness, which resolved with conservative management. No permanent complications were reported after lip biopsy. Nineteen (58%) patients with positive biopsy results had no Sjögren's-specific antibodies. Most patients with positive biopsy results (n = 20, 61%) subsequently started immunomodulatory therapy. Conclusion/UNASSIGNED:Minor salivary gland biopsy can be performed safely and effectively in both the office and the operating room. This procedure provides clinically meaningful information and can be reasonably recommended in patients suspected to have Sjögren's syndrome.

BACKGROUND:The present study aims to assess the quality and availability of online information about fellowships accredited by the American Head & Neck Society (AHNS). METHODS:AHNS directory pages and institutional web sites of 50 AHNS-accredited fellowships were identified. Web pages were scored using 20 standardized criteria including general information, application information, alumni, surgical training, research, and quality-of-life. RESULTS:Median scores for AHNS directory pages and institutional web sites were 11 (range: 7-14) and 10 (4-15), respectively. Faculty listings, contact information, program location, number of positions, and breadth of surgical exposure were the most commonly listed criteria. Less common criteria included didactic schedule, protected academic time, previous research projects, year of accreditation, work-life balance, fellow selection criteria, interview information, and salary. CONCLUSIONS:The AHNS directory and institutional web sites are most comprehensive in general program information and details about surgical training. Information about the application process, work-life balance, and research opportunities were less common.

OBJECTIVE:To analyze clinical outcomes in a series of indeterminate thyroid nodules (ITNs) with repeat fine-needle aspiration (FNA) biopsy and results of genomic classifier. STUDY DESIGN/METHODS:Historical chart review. SETTING/METHODS:Tertiary care center. METHODS:We reviewed FNA samples from subjects with Bethesda III or IV diagnoses from January 2015 to December 2018 at a single institution and selected those with repeat FNA and ThyroSeq testing of the same nodule. Patient demographics, Bethesda classifications, ThyroSeq results, treatment detail, and surgical pathology, when available, were analyzed. RESULTS:< .0001). In excised nodules, the prevalence of malignancy and noninvasive follicular thyroid neoplasm with papillary-like nuclear features was 28% (n = 10) and 22% (n = 8), respectively, and all malignancies were low risk. CONCLUSION/CONCLUSIONS:In this case series, repeat FNA helped patients with ITNs avoid diagnostic surgery through reclassification to benign cytology. The risk of high-risk malignancy in ThyroSeq-positive nodules with repeat indeterminate cytology was low.

OBJECTIVE:Acinic cell carcinoma (AciCC) is a rare, usually low-grade salivary malignancy. Evidence on rates of lymph node metastases (LNMs) is limited in pediatric patients and varies significantly (4%-45%) in adults. We set out to determine and compare rates of LNMs in pediatric and adult AciCC and to analyze their impact on survival, using the National Cancer Database. STUDY DESIGN/METHODS:Historical cohort study. SETTING/METHODS:National Cancer Database. METHODS:All AciCCs of the major salivary glands with complete clinical and pathologic nodal staging were selected between 2010 and 2016. Patient demographics, tumor characteristics, treatment, and survival were analyzed. Univariable and multivariable regression were performed to determine factors associated with LNMs and survival. RESULTS:< .001) were associated with LNM in adult patients. CONCLUSION/CONCLUSIONS:LNMs in AciCC of the major salivary glands are rare in children and adults. However, high-grade and T3-T4 tumors are associated with an increased risk of LNM. LNM is associated with worse survival.

BACKGROUND:Transoral robotic surgery (TORS) was approved by the Food and Drug Administration in 2009 for the treatment of oropharyngeal cancers (oropharyngeal squamous cell carcinoma [OPSCC]). This study investigated the adoption and safety of TORS. METHODS:All patients who underwent TORS for OPSCC in the National Cancer Data Base from 2010 to 2016 were selected. Trends in the positive margin rate (PMR), 30-day unplanned readmission, and early postoperative mortality were evaluated. Outcomes after TORS, nonrobotic surgery (NRS), and nonsurgical treatment were compared with matched-pair survival analyses. RESULTS:From 2010 to 2016, among 73,661 patients with OPSCC, 50,643 were treated nonsurgically, 18,024 were treated with NRS, and 4994 were treated with TORS. TORS utilization increased every year from 2010 (n = 363; 4.2%) to 2016 (n = 994; 8.3%). The TORS PMR for base of tongue malignancies decreased significantly over the study period (21.6% in 2010-2011 vs 15.8% in 2015-2016; P = .03). The TORS PMR at high-volume centers (≥10 cases per year; 11.2%) was almost half that of low-volume centers (<10 cases per year; 19.3%; P < .001). The rates of 30-day unplanned readmission (4.1%) and 30-day postoperative mortality (1.0%) after TORS were low and did not vary over time. High-volume TORS centers had significantly lower rates of 30-day postoperative mortality than low-volume centers (0.5% vs 1.5%; P = .006). In matched-pair analyses controlling for clinicopathologic cofactors, 30-, 60-, and 90-day posttreatment mortality did not vary among patients with OPSCC treated with TORS, NRS, or nonsurgical treatment. CONCLUSIONS:TORS has become widely adopted and remains safe across the country with a very low risk of severe complications comparable to the risk with NRS. Although safety is excellent nationally, high-volume TORS centers have superior outcomes with lower rates of positive margins and early postoperative mortality.

Importance/UNASSIGNED:Genomic classifiers were developed to better guide clinicians in the treatment of indeterminate thyroid nodules (ITNs). To our knowledge, whether there is variation in the diagnostic accuracy of these tests depending on ITN size has not been previously studied. Objective/UNASSIGNED:To analyze the diagnostic performance of a genomic classifier in relation to ITN size. Design, Setting, and Participants/UNASSIGNED:A case series study with medical records review was conducted including all patients with a cytologic diagnosis of ITN managed with genomic classifier testing and surgery from January 2015 to December 2018 at NYU Langone Health. Demographics, ITN characteristics, genomic profiles, treatment, and final pathologic findings were recorded. Data analysis was conducted from March to April 2021. Main Outcomes and Measures/UNASSIGNED:The primary aim was to assess the positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity of a genomic classifier test (ThyroSeq) in relation to ITN size (<2, 2-4, and >4 cm). The secondary aim was to investigate the risk of cancer associated with genetic signatures. Results/UNASSIGNED:Of the 212 patients with 218 ITNs, 158 (74.5%) were women; median (SD) age was 49 (15.6) years. Genomic classifier results were positive in 173 ITNs (79.4%) treated with surgery. In this group of 173 positive ITNs, 46 (26.6%) were malignant on final pathologic testing. Overall, the observed cancer prevalence in the population was 23.9% (52 ITNs). In 45 ITNs that underwent surgery despite a negative genomic classifier interpretation, 6 (13.3%) were malignant. The PPV of a positive test was 27% and the NPV was 87%. The PPV and NPV findings improved as the ITN size increased (<2 cm [n = 98]: PPV, 25%; NPV, 79% vs >4 cm [n = 33]: PPV, 50%; NPV, 89%). Test specificity was higher in larger ITNs (<2 cm: 15% vs >4 cm: 40%; P = .01). Isolated RAS sequence variations were the most common variant identified in malignant nodules (11 [21.1%] of all ITNs), followed by BRAF variants (7 [13.5%] of all ITNs). Conclusions and Relevance/UNASSIGNED:In this case series, the performance of the ThyroSeq test improved for larger ITNs. The risk of cancer in large ITNs with negative test results was low. These data suggest that, in genomic classifier-negative ITNs larger than 4 cm, initial management of thyroid lobectomy may be sufficient.
