RESUMO
OBJECTIVE: Mandibular plate reconstruction (MPR) is often indicated after tumor ablation, osteoradionecrosis excision, and traumatic bone loss to restore oral functionality and facial cosmetics. There are limited analyses identifying risk factors that lead to plate infection (PIn), exposure, and removal ("plate complications"). STUDY DESIGN: Retrospective cohort study. SETTING: Academic tertiary medical center. METHODS: Patients who underwent MPR from 2013 to 2022 were identified. Risk factors for plate complications were analyzed based on demographic, clinical, intraoperative, and postoperative factors. Multivariable analysis was conducted with logistic regression. Survival analysis was conducted with a Cox model. RESULTS: Of the 188 patients analyzed, 48 (25.5%) had a plate complication [infection: 22 (11.7%); exposure: 23 (12.2%); removal: 35 (18.6%)]. Multivariate analysis revealed predictive associations between at least 1 plate complication and the following variables: smoking status, soft tissue defect size, number of plates, average screw length, and various postoperative complications. Other associations approached the threshold for significance. Prior and adjuvant radiation therapy, type of free flap, stock versus custom plates, and perioperative antibiotic prophylaxis regimens were not associated with plate complications. No plate complication was independently associated with lower overall survival. PIn (hazard ratio, HR: 7.99, confidence interval, CI [4.11, 15.54]) and exposure (HR: 3.56, CI [1.79, 7.08]) were independently associated with higher rates of plate removal. CONCLUSION: Plate complications are relatively common after MPR. Smoking history, specific disease characteristics, hardware used during surgery, and postoperative complications may help identify higher-risk patients, but additional larger-scale studies are needed to validate our findings and resolve discrepancies in the current literature.
RESUMO
OBJECTIVES: To determine whether 2 different methods of post-operative head and neck free flap monitoring affect flap failure and complication rates. METHODS: A retrospective chart review of 803 free flaps performed for head and neck reconstruction by the same microvascular surgeon between July 2013 and July 2020 at 2 separate hospitals within the same healthcare system. Four-hundred ten free flaps (51%) were performed at Hospital A, a medical center where flap checks were performed at frequent, scheduled intervals by in-house resident physicians and nurses; 393 free flaps (49%) were performed at Hospital B, a medical center where flap checks were performed regularly by nursing staff with resident physician evaluation as needed. Total free flap failure, partial free flap failure, and complications (consisting of wound infection, fistula, and reoperation within 1 month) were assessed. RESULTS: There were no significant differences between Hospitals A and B when comparing rates of total free flap failure, partial free flap failure, complication, or re-operation (P = .27, P = .66, P = .65, P = .29, respectively). There were no significant differences in urgent re-operation rates for flap compromise secondary to thrombosis and hematoma (P = .54). CONCLUSIONS: In our series, free flap outcomes did not vary based on the degree of flap monitoring by resident physicians. This data supports the ability of a high-volume, well-trained, nursing-led flap monitoring program to detect flap compromise in an efficient fashion while limiting resident physician obligations in the age of resident duty hour restrictions.

Objectives: Determine variability in intra- and post-operative management of tracheostomies (trachs) at our institution as existing literature suggests that trachs are a frequent trigger for airway-related emergencies. Catalyze the development of an institution-wide protocols for trach care. Methods: A 39-question online survey was sent to 55 providers who perform open and percutaneous trachs at three of the hospitals within our large, urban, academic medical center. These providers were identified by surveillance of the operating room schedules for 1 year. Results: The survey was completed by 40 of the 53 eligible providers (75.5%). Response rate by question varied. Respondents included members of all departments that perform trachs at our institution (Otorhinolaryngology, Trauma Surgery, Thoracic Surgery, General Surgery, Cardiovascular Surgery and Interventional Pulmonology).While most responses demonstrated uniformity in practice, notable variations included the following: 80% of percutaneous trach providers stated that morbid obesity was not a contraindication to performing a trach outside of the operating room (n = 20) while 58% of open trach providers stated that morbid obesity was a contraindication; only 35% of open trach providers perform a Bjork flap (n = 350). The survey also identified significant variability in practice with regards to timing of trach suture removal. Discussion: Lack of uniformity was identified in several practices related to intra- and post-operative tracheostomy care. Results did, however, trend toward consensus in many areas. The results are being used to establish a more consistent approach to tracheostomy management across our institution to ensure standardization of practice amidst the rapidly evolving practices of trach placement. Implications for practice: With ongoing evolution in the methods of trach placement and its management, the concepts put forth here will be a resource for health care providers at other institutions to consider intra-institutional analysis and establishment of practice standardization.
RESUMO
Objective: To quantify the financial impact of the coronavirus disease (COVID-19) pandemic on an academic otolaryngology department. Methods: A year-over-year comparison was used to compare department revenue from April 2020 and April 2021 as a percentage of baseline April 2019 activity. Results: At the onset of the COVID-19 pandemic in April 2020, total department charges decreased by 83.4%, of which outpatient clinic charges were affected to the greatest extent. One year into pandemic recovery, department charges remained down 6.7% from baseline, and outpatient clinic charges remained down 9.9%. The reduction in outpatient clinic charges was mostly driven by a decrease in in-office procedure charges. Conclusion: Given that precautions to mitigate the risk of viral transmission in the health care setting are likely to be long-lived, it is important to consider the vulnerabilities of our specialty to mitigate financial losses going forward.
RESUMO
OBJECTIVES: Increasing use of transoral robotic surgery (TORS) is likely to impact outcomes for HPV+ oropharyngeal squamous cell carcinomas (OPSCCs). We aimed to describe oncologic outcomes for a large HPV+ OPSCC cohort after TORS and develop a risk prediction model for recurrence under this treatment paradigm. MATERIALS AND METHODS: 634 HPV+ OPSCC patients receiving TORS-based therapy at a single institution were reviewed retrospectively to describe survival across the entire cohort and for patients suffering recurrence. Risks for distant metastatic recurrence (DMR) and locoregional recurrence (LRR) were modeled using multivariate logistic regression analyses of case-control sub-cohorts. RESULTS: 5-year overall and recurrence-free survival were 91.2% and 86.1%, respectively. 5-year overall survival was 52.5% following DMR and 83.3% after isolated LRR (P = .01). In case-control analyses, positive surgical margins were associated with DMR (adjusted OR 5.8, CI 2.1-16.0, P = .001), but not isolated LRR, and increased DMR risk 4.2 fold in patients with early clinical stage disease. By contrast, LRR was associated with not receiving recommended adjuvant therapy (OR 13.4, CI 6.3-28.5, P < .001). CONCLUSIONS: This study sets a benchmark for oncologic outcomes from HPV+ OPSCC after TORS-based therapy. Under this treatment paradigm, margins are relevant for assessing lethal recurrence risk during clinical trial design and post-treatment surveillance.

BACKGROUND: Although meningiomas are the most common central nervous system neoplasms, extracranial metastases are exceedingly rare. There are even fewer reports of metastatic meningiomas to the neck. METHODS: We described a patient with multiply recurrent orbital meningioma with metastasis to the neck found incidentally during neck exploration for composite resection and free tissue reconstruction. We performed a systematic review for all records pertaining to metastatic meningiomas to the cervical regions. RESULTS: We found 9 previous reports of cervical metastatic meningiomas. Almost all cases underwent extensive local resection. There was no evidence of an association between the histological grade of the tumor and risk of metastasis to the neck. Cervical lymph node dissemination is more common in patients presenting after previous primary tumor resection. CONCLUSIONS: In the context of a neck mass, our findings suggest that metastatic meningioma should be included in the differential diagnosis, especially in patients with previous resections.

OBJECTIVES: Sex differences in surgically treated HPV-associated oropharyngeal squamous cell carcinoma are not defined due to the low number of affected women. We explored the oncologic outcomes of men and women with p16-positive oropharyngeal squamous cell carinoma treated with primary surgery. MATERIALS AND METHODS: Retrospective analysis of patients with HPV-related oropharyngeal cancer treated with surgery and pathology guided adjuvant therapy from 2007 to 2017. Primary end point was recurrence-free and overall survival. RESULTS: Of 468 men (86.7%) and 72 women (13.3%), women presented more often with clinical N0 nodal disease (25% vs 12.2%). There were no differences in adverse pathologic features or T stage, although women were more likely to present with N0 disease (16.7% vs 10%), less N2 disease (6.9% vs 17.7%, p = 0.03), and more stage I disease (88.9% vs 75%). As a result, women were more likely to undergo surgery alone (30.6% vs 14.1%) while men were more likely to require adjuvant radiation therapy (47.2% vs 36.1%). Four women (5.6%) and 30 men (6.4%, p = 0.8) died during follow-up. Multivariate analysis controlling for age, sex, treatment, and pathologic stage demonstrated no differences in overall survival between men and women. There were no differences in recurrence-free or overall survival between men and women at two and five years. CONCLUSIONS: Although women undergoing transoral robotic surgery for HPV+ oropharyngeal squamous cell carcinoma may have less advanced disease, upfront surgery with pathology-guided adjuvant therapy produces similar oncologic results in men and women while accounting for disease burden.

Sialendoscopy is a minimally invasive technique that facilitates the diagnosis and treatment of sialolithiasis. This case series presents the novel use of sialendoscopy to treat sialodocholithiasis in six patients with a non-functional or surgically absent submandibular gland by a single surgeon at the University of Pennsylvania Health System between March 2013 and December 2019. The four female and two male patients had a median age of 56 years and mean follow-up of 16.2 months (range 1-44.5). All stones were successfully removed using sialendoscopy, and in 5 patients a combined approach was utilized. All patients remain asymptomatic at last clinical follow-up. We conclude that sialendoscopy is a viable, minimally invasive method for managing sialodocholithiasis in patients with prior submandibular gland excision or atretic gland. It is also useful as an assistive tool when approaching complex transcervical or transoral procedures in previously instrumented patients.
RESUMO
OBJECTIVES: To assess the prognostic significance of oligometastatic versus polymetastatic disease in human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC), and to evaluate the impact of definitive tumor directed therapy on the survival outcomes for patients with oligometastatic disease when compared to systemic therapy. MATERIALS AND METHODS: This was a retrospective observational cohort study of patients with HPV-associated OPSCC who developed distant metachronous metastatic disease after undergoing initial primary surgical management from 2008 to 2017. We classified patients based on the extent of metastatic disease [Oligometastatic (≤5 metastases) and polymetastatic (>5 metastases)], and the initial treatment of metastatic disease [definitive tumor directed therapy (all metastases treated with surgery or radiotherapy) versus upfront systemic therapy]. RESULTS: Among 676 patients undergoing primary surgical management for HPV-associated OPSCC, 39 patients (5.8%) developed metastases after a median follow-up of 29.6 months (range 4.5-127.0). Of the 34 metastatic patients who met study criteria, 26 (76.5%) were oligometastatic and 8 (23.5%) were polymetastatic. Oligometastatic patients had improved median overall survival (OS) compared to polymetastatic patients (47.9 vs. 22.7 months, p = 0.036). For oligometastatic patients, definitive tumor directed therapy was associated with an improved median progression free survival (not reached vs 6.13 months, p = 0.001) and median OS (not reached vs 40.7 months, p = 0.004). CONCLUSION: In a cohort of patients surgically treated for HPV-associated OPSCC, metachronous metastatic disease was uncommon and, in most cases, considered oligometastatic. Oligometastasis portends a favorable prognosis and definitive tumor directed therapy may be associated with improved overall survival in these patients. Future multi-institutional efforts are warranted to further demonstrate the impact of definitive tumor directed therapy on disease outcomes.

BACKGROUND: Patients with human papillomavirus (HPV)-negative oropharyngeal squamous cell carcinoma (OPSCC) continue to experience disappointing outcomes following chemoradiotherapy (CRT) and appreciable morbidity following historical surgical approaches. We aimed to investigate the oncologic outcomes and perioperative morbidity of a transoral robotic surgery (TORS) approach to surgically resectable HPV-negative OPSCC. METHODS: Retrospective analysis HPV-negative OPSCC patients who underwent TORS, neck dissection and pathology-guided adjuvant therapy (2005-2017). RESULTS: Fifty-six patients (91.1% stage III/IV) were included. Three-year overall survival, locoregional control, and disease-free survival were 85.5%, 84.4%, and 73.6%, respectively (median follow-up 30.6 months, interquartile range 18.4-66.6). Eighteen (32.1%) patients underwent adjuvant radiotherapy and 20 (39.3%) underwent adjuvant CRT. Perioperative mortality occurred in one (1.8%) patient and hemorrhage occurred in two (3.6%) patients. Long-term gastrostomy and tracheostomy rates were 5.4% and 0.0%, respectively. CONCLUSION: The TORS approach for resectable HPV-negative OPSCC can achieve encouraging oncologic outcomes with infrequent morbidity.

BACKGROUND: Patients with oropharyngeal cancer who undergo transoral robotic surgery (TORS) and have high-risk features generally receive adjuvant chemoradiotherapy or trimodality therapy (TMT). The notion that TMT leads to high toxicity is largely based on studies that included human papilloma virus (HPV)-negative cancers and/or nonrobotic surgery; we sought to describe outcomes in HPV-associated oropharyngeal squamous cell cancer (HPV + OPSCC) undergoing TORS-TMT. METHODS: In consecutive patients with HPV + OPSCC receiving TMT at an academic center from 2010 to 2017, survival was estimated using Kaplan-Meier methodology, and toxicities were ascertained via chart review. RESULTS: In our cohort of 178 patients, 5-year survival was 93.6%. Feeding tube rates were 25.8% at therapy completion and 0.7% at 1 year. Rates of grade ≥ 3 kidney injury, anemia, and neutropenia in cisplatin-treated patients were 2.7%, 3.4%, and 11.0%, respectively. CONCLUSIONS: Patients with HPV + OPSCC who underwent TORS-TMT had excellent survival and low rates of toxicity and feeding tube dependence. These outcomes compare favorably to historical cohorts treated with definitive chemoradiotherapy.

OBJECTIVES: To determine whether up-front trans-oral robotic surgery (TORS) for clinically-staged locally-advanced human papillomavirus (HPV)-related oropharyngeal cancer is associated with oncologic and survival outcomes comparable to early-stage (cT1/T2) tumors. MATERIALS AND METHODS: Retrospective cohort study of 628 patients with HPV-related oropharyngeal cancer who underwent up-front TORS from 2007 to 2017. Patients were stratified into two cohorts based on early-stage (cT1/2) versus locally-advanced (cT3/4) tumor at presentation. RESULTS: We identified 589 patients who presented with early-stage tumors, and 39 patients with locally-advanced tumors. Of these, 73% of patients required adjuvant radiation, and 33% required adjuvant chemoradiation. There was no significant difference in the administration of adjuvant radiation or chemoradiation between the two cohorts. Patients in the locally-advanced disease cohort were significantly more likely to have Stage II/III disease by clinical and pathologic criteria by American Joint Committee on Cancer 8th edition criteria (p < 0.001). However, there was no significant difference in 5-year overall survival (OS) or recurrence-free survival (RFS) based on Kaplan-Meier survival estimates between the two cohorts (p = 0.75, 0.6, respectively), with estimated OS of 91% at 5 years, and estimated RFS of 86% at 5 years across the study population. CONCLUSIONS: Up-front TORS offers favorable survival outcomes for appropriately selected locally-advanced cases of HPV-related oropharyngeal cancer. Furthermore, up-front TORS is comparably effective in allowing avoidance of adjuvant therapy, particularly chemotherapy, in both cT1/T2 and locally-advanced HPV-positive oropharyngeal cancer. In the absence of clear technical contraindication to surgery, cT3/T4 classification should not be considered an absolute contraindication to surgery.

OBJECTIVES: Guidelines for transoral robotic surgery (TORS) have generally regarded patients with retropharyngeal carotid arteries as contraindicated for surgery due to a theoretical risk of intraoperative vascular injury and/or perioperative cerebrovascular accident. We aimed to demonstrate that careful TORS-assisted resection and free flap coverage could not only avoid intraoperative injury and provide a physical barrier for vessel coverage but also achieve adequate margin control. STUDY DESIGN: Retrospective cohort analysis. METHODS: Retrospective review of patients with oropharyngeal malignancies and radiologically confirmed retropharyngeal carotid arteries who underwent TORS, concurrent neck dissection, and free flap reconstruction between 2015 and 2019. RESULTS: Twenty patients were included, 19 (95.0%) with tonsillar tumors and one (5.0%) with a tongue base tumor with significant tonsillar extension. Eighteen patients (90.0%) received a radial artery forearm flap, one (5.0%) an ulnar artery forearm flap, and one (5.0%) an anteromedial thigh flap. All 20 (100%) flaps were inset through combined transcervical and transoral approaches without mandibulotomy. There were no perioperative mortalities, carotid injuries, oropharyngeal bleeds, cervical hematomas, or cerebrovascular accidents. One patient (5.0%) had a free flap failure requiring explant. All patients underwent decannulation and resumed a full oral diet. The mean length of hospitalization was 6.8 (standard deviation 1.2) days. One (5.0%) patient had a positive margin. CONCLUSION: In this analysis, 20 patients with oropharyngeal malignancy and retropharyngeal carotid arteries underwent TORS, neck dissection, and microvascular reconstruction without serious complication (perioperative mortality, vascular injury, or neurologic sequalae) with an acceptable negative margin rate. These results may lead to a reconsideration of a commonly held contraindication to TORS. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:E821-E827, 2021.

Importance: Although routine postoperative care for microvascular free flap reconstruction typically involves admission to the intensive care unit (ICU), few studies have investigated the effect of postoperative care setting on clinical outcomes and institution cost. Objectives: To determine the value of non-ICU-based postoperative management for free tissue transfer for head and neck surgery, in terms of clinical outcomes and cost-effectiveness. Design, Setting, and Participants: This is a retrospective cohort study of two groups of adults who underwent vascularized free tissue transfer from October 2013 to October 2017 at an academic tertiary care center and community-based hospital, respectively. Postoperative management differed such that the first group recovered in a protocol-driven non-ICU setting and the second group was cared for in a planned admission to the ICU. A single surgeon performed all tissue harvest and reconstruction at both centers. Main Outcomes and Measures: Descriptive statistics and cost analyses were performed to compare clinical outcomes and total surgical and downstream direct cost to the institution between the two patient groups. Categorical variables were compared using χ2 test where appropriate. Results: Among a total of 338 patients who underwent microvascular free flap reconstruction for head and neck surgical defects, there was no significant difference in patient characteristics such as demographics, comorbidities, history of surgical resection, prior free flap, and locoradiation between the postoperative ICU cohort (n = 146) and protocol-driven non-ICU cohort (n = 192). There were 16 patients in the non-ICU group who spent >3 days in the ICU postoperatively secondary to patient comorbidities and patient care priorities. Still, the average ICU length of stay was 7 days (interquartile range [IQR] 6-9 days) for the planned ICU cohort versus 1 day (IQR 0-1) for the non-ICU group (p < 0.00001). There was no difference in operative variables such as donor site, case length, or total length of stay, and postoperative management in the ICU versus non-ICU setting resulted in no significant difference in terms of flap survival, reoperation, readmission, and postoperative complications. However, average cost of care was significantly higher for patients who received ICU-based care versus non-ICU postoperative care. Specifically, room and board were 239% more costly for the planned ICU care group than the non-ICU setting (p < 0.00001). Conclusions and Relevance: This study demonstrates that postoperative management after vascularized free tissue transfer in a non-ICU setting is equivalent to standard ICU-based management, in terms of clinical outcomes, while being less costly.

BACKGROUND: Some patients with human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) do not receive guideline-recommended postoperative radiation therapy (PORT) following primary transoral robotic surgery (TORS). METHODS: Three-hundred and sixty-four patients with treatment-naïve, HPV-associated OPSCC were recommended to receive PORT based on clinicopathological features following TORS. Patients were stratified based on if they received PORT. Oncologic outcomes were compared. RESULTS: The 3-year locoregional failure (LRF) was 32% in patients who did not receive PORT and 4% in patients who received PORT (P < .001). Despite increased LRF, avoiding PORT was not associated with increased 3-year distant metastasis rates (8% vs 4%, P = .56) or worse 3-year survival (95% vs 98%, P = .34). Recurrences in the surgery alone cohort varied between local and regional sites and were often successfully salvaged. CONCLUSIONS: Patients with HPV-associated OPSCC who do not receive indicated PORT have an increased risk of LRF but similar survival due to high salvage rates.

OBJECTIVE: Despite epidemiologic evidence that second primaries occur infrequently in HPV (human papillomavirus)-associated oropharyngeal squamous cell carcinoma, recent recommendations advocate for elective contralateral palatine tonsillectomy. We aimed to study this discordance and define the necessary extent of up-front surgery in a large contemporary cohort with long-term follow-up treated with unilateral transoral robotic surgery. We hypothesized that second primaries are discovered exceedingly rarely during follow-up and that survival outcomes are not compromised with a unilateral surgical approach. STUDY DESIGN: Retrospective cohort analysis. SETTING: Tertiary care academic center between 2007 and 2017. METHODS: Records for patients with p16-positive oropharyngeal squamous cell carcinoma of the tonsil and workup suggestive of unilateral disease who underwent ipsilateral transoral robotic surgery were analyzed for timing and distribution of locoregional recurrence, distant metastases, and second primary occurrence as well as survival characteristics. RESULTS: Among 295 included patients, 21 (7.1%) had a locoregional recurrence; 17 (5.8%) had a distant recurrence; and 3 (1.0%) had a second primary during a median follow-up of 48.0 months (interquartile range, 29.5-62.0). Only 1 (0.3%) had a second primary found in the contralateral tonsil. The 2- and 5-year estimates of overall survival were 95.5% (SE, 1.2%) and 90.1% (SE, 2.2%), respectively, while the 2- and 5-year estimates of disease-free survival were 90.0% (SE, 1.8%) and 84.7% (SE, 2.3%). CONCLUSION: Second primary occurrence in the contralateral tonsil was infrequent, and survival outcomes were encouraging with unilateral surgery. This provides a rationale for not routinely performing elective contralateral tonsillectomy in patients whose workup suggests unilateral disease.

Importance: While early epidemiologic studies ascribed increases in the incidence of human papillomavirus-associated oropharyngeal cancers to middle-aged patients, recent analyses have demonstrated an increasing median age of diagnosis. Treatment of patients older than 70 years is controversial as their inclusion in the practice-defining clinical trials has been limited and the survival benefit conferred by chemotherapy may be outweighed by treatment toxic effects. Objective: To assess the oncologic outcomes of older adults with human papillomavirus-associated oropharyngeal cancer who underwent upfront transoral robotic surgery and pathologic characteristics-guided adjuvant therapy in a large cohort of patients with close follow-up. Design, Setting, and Participants: A retrospective cohort analysis was conducted in a tertiary care academic medical center between January 1, 2010, and December 30, 2017. Patients aged 70 years or older at time of diagnosis with biopsy-proven and surgically resectable p16-positive oropharyngeal cancers were included. Data analysis was conducted from March 1 to June 1, 2020. Exposures: Transoral robotic surgery oropharyngeal resection and neck dissection with pathologic characteristic-guided adjuvant therapy. Main Outcomes and Measures: Three-year estimates of disease-specific survival, overall survival, and disease-free survival, as well as rates of adjuvant therapy (radiotherapy and chemoradiotherapy) and perioperative complications. Results: Seventy-seven patients were included (median age, 73.0; interquartile range, 71.0-76.0; range, 70-89 years); of these, 58 were men (75.3%). Perioperative mortality was 1.3% and the rate of oropharyngeal hemorrhage was 2.6%. Twenty-seven patients (35.1%) underwent postoperative radiotherapy and 20 patients (26.0%) underwent postoperative chemoradiotherapy. The median length of follow-up was 39.6 (range, 0.1-96.2) months, and the 3-year estimates of survival were 92.4% (95% CI, 82.4%-96.9%) for disease-specific survival, 90.0% (95% CI, 79.4%-95.0%) for overall survival, and 84.3% (95% CI, 73.4%-91.0%) for disease-free survival. Conclusions and Relevance: The findings of this cohort study suggest that transoral robotic surgery and pathologic characteristic-guided adjuvant therapy can provide beneficial survival outcomes, infrequent perioperative mortality, and, for most carefully selected older adults, obviate the need for chemotherapy.

INTRODUCTION: Mucoepidermoid carcinoma (MEC) of the upper aerodigestive tract (UADT) is an uncommon malignancy, with limited literature available on its clinical and pathologic characteristics. Here, we describe the behavior of MEC of the UADT including pathologic characteristics and predictors of nodal metastasis. METHODS: Retrospective cohort study of patients with MEC of the UADT treated at an academic medical center from January 2008 to May 2018. Data was collected about demographics and tumor characteristics including clinical and histological data. The two-tailed Student t test and χ2 analysis were performed to assess for predictors of nodal metastasis. RESULTS: We identified 44 patients with minor salivary gland MEC of the oral cavity (OC) and oropharynx (OP). All patients were treated with primary site surgery. The primary site was the OC in 25 patients (57%) and OP in 19 (43%). Low-grade histology was seen in 27 specimens (61.4%), intermediate histology in 9 specimens (20.5%), and high-grade histology in 8 specimens (18.2%). Perineural invasion was noted in 10 specimens (22.7%). Neck dissection was performed in 17 patients (39%), with pathologically positive nodes found in 9 (20.5%). Notably, 5 of the 9 positive nodal specimens were found in clinically node-negative necks. Pathologically positive cervical lymph nodes were significantly associated with the OP as the primary site (p = 0.0005), perineural invasion (p = 0.012), lymphovascular invasion (p < 0.001), and high-grade histology (p = 0.004) in the primary specimen. DISCUSSION: MEC of the UADT is an uncommon malignancy. Our findings suggest elective neck dissection should be considered with perineural and lymphovascular invasion, high-grade tumor, and the OP as the primary site.

OBJECTIVES: Carcinosarcomas of the salivary gland are rare neoplasms and have been described arising de novo or in association with pleomorphic adenoma (PA). PLAG1 and HMGA2 translocations are known to occur in PAs and carcinomas ex PA but are mutually exclusive. METHODS: We report a case of a carcinosarcoma in the parotid gland of a 77-year-old man with unusual anaplastic sarcomatoid giant cell morphology. RESULTS: Microscopically, a small separate PA was found adjacent to the carcinosarcoma. By conventional notion, the PA and carcinosarcoma would be considered related, as carcinosarcomas are well known to arise from PAs (carcinosarcoma ex PA). However, fluorescence in situ hybridization (FISH) assay demonstrated PLAG1 translocation in the carcinosarcoma and HMGA2 translocation in the separate PA. CONCLUSIONS: These findings support that the carcinosarcoma likely originated from another PA with a PLAG1 translocation or de novo but not from the coexisting PA harboring a different translocation. To our knowledge, the case is the first to demonstrate PLAG1 translocation by FISH in a sarcomatous component of any parotid gland tumor, which may help better classify these tumors. In addition, multiple PAs are commonly found in the salivary gland, and to our knowledge, our case is the first to demonstrate that the same parotid gland can host PAs and PA-related tumors with different translocations.
