The present study characterizes national trends in the utilization of adjuvant chemotherapy to treat salivary gland malignancies.The National Cancer Database was queried for salivary gland malignancies treated by surgery with radiation in 2004-2019. Proportions of patients receiving adjuvant chemotherapy over the study period were analyzed by linear regression. The impact of chemotherapy on overall survival was assessed using Kaplan-Meier and Cox proportional hazards analyses.Among 15 965 patients meeting inclusion criteria, 2355 (14.8%) received adjuvant chemotherapy. Chemotherapy utilization significantly increased from 4.9% to 16.5% over the study period (p 0.001). No survival benefit was observed with adjuvant chemotherapy on propensity score-matched Kaplan-Meier analysis (HR: 0.98; 95% CI: 0.86-1.11; p = 0.72) or multivariable Cox regression (HR: 0.92; 95% CI: 0.78-1.09; p = 0.34).Adjuvant chemotherapy has been increasingly utilized to treat salivary gland malignancies in recent years. Our findings highlight the importance of obtaining high-quality prospective data regarding the benefit of chemotherapy.

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.Historical cohort study.National Cancer Database.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.We identified 57 (4.6%) pediatric patients (18 years) and 1192 (95.4%) adults with AciCC. Clinical LNMs were rare in pediatric patients (n10) and adults (n = 88, 7.4%). Occult LNMs were uncommon in pediatric patients (n5) and adults (n = 41, 4.6%). Three-year overall survival for pediatric patients was 97.8%. Adults with LNM had worse 3-year overall survival than those without (66.0% vs 96.3%,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.

Assess the testing rates and prognostic significance of human papilloma virus (HPV) status in hypopharynx malignancies.Historical cohort study.National Cancer Database.Review of the National Cancer Database was conducted between 2010 and 2017 for squamous cell carcinomas (SCCs) of the hypopharynx. We investigated how often the tumors were tested for HPV and whether it was associated with survival outcomes.A total of 13,269 patients with hypopharynx malignancies were identified. Most cases were not tested for HPV status (n = 8702, 65.6%). Of those tested, 872 (19.1%) were positive for HPV and 3695 (80.9%) were negative. The proportion of nonoropharyngeal SCCs tested for HPV increased nearly every year during the study, with roughly one-third of cases (31.9%) being tested in 2017. In the facilities classified as high-testing centers of nonoropharyngeal SCCs of the head and neck, 18.7% of hypopharyngeal tumors were HPV positive. HPV-negative status was associated with worse survival on multivariable analysis. In propensity score-matched analysis controlling for all factors significant in multivariable regression, 2-year survival remained higher in the HPV-positive cohort (77.7% vs 63.1%,HPV-positive tumors constitute a sizable minority of hypopharynx tumors and are associated with improved survival. Expansion of HPV testing to hypopharynx malignancies may be warranted.

To describe patterns of primary surgical treatments in patients with T4b oral cavity squamous cell carcinoma (OCSCC).Historical cohort study.National Cancer Database.Review of the National Cancer Database between 2004 and 2017 for all T4b OCSCCs. Only patients with curative treatment methods were included in the survival analysis. Surgical and nonsurgical outcomes were compared by multivariable and propensity score matching analysis.A total of 1515 cases of T4b OCSCC were identified. A minority of patients (n = 363, 24.0%) underwent curative treatment; among these, 206 (56.7%) underwent primary surgery. Median length of follow-up was 24 months. The 90-day mortality of patients who underwent surgical treatment was 1.0%. The 2-year survival was higher for patients who underwent surgery + chemoradiotherapy (CRT) as compared with CRT (64.6% vs 45.2%,A minority of patients with T4b OCSCC undergo treatments with curative intent. A subset of patients underwent primary surgical treatment, which was associated with longer survival. The T4b classification might entail a heterogenous group, and further studies in revision of this classification might be justified.

To investigate the patterns of care and outcomes of treatment of early stage tonsil cancers, controlling for human papillomavirus (HPV) status.Historical cohort study.National Cancer Database (NCDB).Review of the NCDB between 2010 and 2017 for all T1-2N0M0 tonsillar squamous cell carcinoma (SCC). Demographics, clinical characteristics, HPV status, treatment regimens, and survival were analyzed.A total of 4720 patients were identified with early stage SCC of the tonsil. Most were tested for HPV (2759 [58.5%]). Among tested patients, 1758 (63.7%) were positive for HPV and 1001 (36.3%) were negative for HPV. HPV-positive patients had higher 3-year survival compared to HPV-negative patients (93.2% vs 77.8%,Surgical- or radiation-based treatment resulted in similar survival in early stage HPV-positive tonsil cancer. Surgical-based treatments were associated with longer survival in HPV-negative cancers. These findings should be further investigated in a randomized prospective trial.

BACKGROUND: We examine the prognostic implications of mid-course nodal response in oropharyngeal cancer (OPX) to radiation therapy. METHODS: In 44 patients with node-positive OPX undergoing concurrent chemoradiation, nodal volumes were measured on cone beam CTs from days 1, 10, 20, and 35. Nodal decrease (ND) was based on percent shrinkage from day 1. RESULTS: At a median follow-up of 17 months, the 2-year disease-free survival (DFS), locoregional control (LRC), distant metastasis-free survival (DMFS), and overall survival (OS) were 87%, 92%, 89%, and 92%, respectively. Patients with ND ≥43% at D20 had improved LRC (100% vs 78.4%, P = .03) compared to D20 ND

To investigate differences in epidemiology of oropharyngeal squamous cell carcinoma (OPSCC) with regards to human papillomavirus (HPV), race, and socioeconomic status (SES) using the National Cancer Database (NCDB).Population-based cohort study.Racial and socioeconomic disparities in survival of OPSCC have been previously acknowledged. However, the distribution of HPV-related cancers and its influence on survival in conjunction with race and SES remain unclear.All patients with OPSCC in the NCDB with known HPV status from 2010 to 2016 were included. Differences in presentation, HPV status, treatment, and outcomes were compared along racial and socioeconomic lines. Univariable and multivariable Cox regression survival analyses were performed.In total, 45,940 patients met criteria. Most were male (38,038, 82.8%), older than 60 years (23,456, 51.5%), and white (40,156, 87.4%), and lived in higher median income areas ($48,000, 28,587, 62.2%). Two-thirds were HPV positive (31,007, 67.5%). HPV-negative disease was significantly more common in lower SES ($38,000, 2937, 41.5%,Significant differences in HPV status exist between socioeconomic and racial groups, with HPV-negative disease more common among blacks and lower SES. When controlling for HPV status, race and SES still influence outcomes in oropharyngeal cancers.

Objectives/hypothesis To determine if a long segment of trachea can be transplanted as a vascularized organ and to determine if a tracheal transplant is a potential surgical option for a long-segment circumferential tracheal defect. Study design Animal model. Methods Four (two donors and two recipients) adult domestic Yorkshire swine were used. Two sets of transplants were performed from a donor to recipient pig. The transplant was placed heterotopically (not in continuity with the airway), and the recipient animals were monitored for 14 days to ensure the transplants were well vascularized. Immunosuppressive therapies included methylprednisolone, cyclosporine, and azathioprine. Gross as well as histological examination of multiple tissues types including mucosa, cartilage, muscle, and blood vessels were performed postsacrifice on day 14. Results Recipient animal weights ranged from 40 to 42 kilograms. Both recipient pigs survived the full 14 days of study and exhibited normal activity and appetite. Ischemia time of transplanted grafts ranged from 63 to 72 minutes. Transplanted tracheas included a minimum of 15 cartilaginous rings and measured greater than 10 cm in length. Both grafts maintained a robust blood supply throughout the duration of study. Conclusions The entire visceral compartment can be reliably transplanted, either as a single component (trachea) or as a chimeric flap with multiple components (trachea, esophagus, larynx, and pharynx). Further studies in the swine model should be considered to study the effects of transplanting the trachea orthotopically into the native airway. Further studies are needed into the reliability of this technique of transplantation in humans. Level of evidence NA Laryngoscope, 128:S1-S9, 2018.

Background Unilateral radiotherapy (RT) of oropharyngeal carcinomas is accepted for patients with lateralized primary and low-volume nodal disease. Utilizing prospectively defined criteria of laterality and staging positron emission tomography (PET)/CT, we studied outcomes in patients with advanced-stage oropharyngeal cancer undergoing unilateral RT. Methods Thirty-seven patients with oropharyngeal tumors >1 cm from midline regardless of node status underwent unilateral RT and were followed prospectively. Patient characteristics: T1 = 11; T2 = 22; T3 = 4; N0 = 3; N1 = 9; N2a = 3; N2b = 21; and Nx = 1. Dosimetry were determined and weekly National Comprehensive Cancer Network (NCCN) distress thermometer data were collected. Results At median follow-up of 32 months, 3-year locoregional control, contralateral regional failure, distant metastasis-free survival, and disease-free survival were 96%, 0%, 7%, and 93%, respectively. Conclusion Low rates of contralateral neck failure are demonstrated utilizing prospectively defined criteria for unilateral RT. The tolerances of contralateral organs are respected and patients report low to moderate levels of distress throughout treatment.

Background Review patient and defect factors in which this donor site is an optimal choice for reconstruction and to discuss strategies to overcome the perceived drawbacks of this system of flaps. Methods A retrospective medical chart review was conducted on all patients who underwent the subscapular system of free flaps for head and neck reconstruction. Results Ninety-eight reconstructions were performed for mandibular defects, 4 for maxillary defects alone and 3 for combined mandible-maxilla defects. The overall success rate was 98%. Conclusion The subscapular system of free flaps is an excellent option in patients for whom the alternative donor sites are either not usable or lack the associated soft tissue elements required for a successful reconstruction. This flap should also be considered as a first choice for patients with complex/extensive surgical defects requiring multiple, independently mobile, soft tissue components; in patients who will benefit from a large muscle flap placed over the vital structures in the neck; patients of advanced age; and patients in whom early mobilization is critical. © 2014 Wiley Periodicals, Inc.

Objectives/Hypothesis To report tolerance and toxicity of radiotherapy (RT) with or without chemotherapy in HIV seropositive patients with squamous cell carcinoma of the head and neck (SCCHN). Methods This is a single institution retrospective study of 73 HIV seropositive patients with SCCHN treated from January 1997 through 2010. Stages I, II, III, and IV were 8%, 10%, 24%, and 58%, respectively. The median age at RT, HIV diagnosis. and the duration of HIV seropositive were 51 (32–72), 34 (25–50), and 11 (6–20) years, respectively. Patients were treated definitively with RT alone (35%) or concurrent chemo-RT (65%). Median dose of 70 Gy (66–70) was delivered to the gross disease. Median duration of treatment was 52 (49–64) days. Fifty patients (70%) were on HAART. Results RT± chemotherapy induced acute toxicity was: median weight loss 20 pounds (6–40), 100% developed dysgeusia and xerostomia (grades 1–3). Acute mucositis and dysphagia/odynophagia grades ≤2 and 3 were 83% and 17%, respectively. Treatment breaks in excess of 10, 7, and 3 days were found in 5%, 13%, and 15% of patients, respectively. With a median follow-up of 4 years (2–12) the RT ±chemotherapy induced late dysphagia and xerostomia grades >2 were 26% and 23% of patients, respectively. Conclusion Our data show that primary RT ±chemotherapy for HIV seropositive SCCHN is less tolerated compared to the historical data for SCCHN without HIV. Level of Evidence 2b.

Background. In the neck, the recipient vessels most frequently used for microsurgical reconstruction are compromised by prior surgery and radiation. Methods. We conducted a retrospective chart review of all patients who underwent microvascular reconstruction between July 2001 and June 2005. Donor vessels, vein grafts, and flap survival were examined. Results. Fourteen of 197 patients (7%) were identified with a vessel-depleted neck. All patients had undergone a prior neck dissection and radiation (100%) or chemoradiation (42%). Free flap revascularization was achieved using the transverse cervical artery with a vein graft and a cephalic vein (4 patients), thoracoacromial artery and cephalic vein (3 patients), internal mammary artery and vein (3 patients), and inferior thyroid artery and cephalic vein (1 case). In 3 patients, the reverse flow thoracodorsal artery and cephalic vein were used to vascularize the scapular flap. Conclusion. The cephalic vein, transverse cervical, internal mammary, and thoracoacromial vessels represent reliable alternatives in the vessel-depleted neck. © 2007 Wiley Periodicals, Inc. Head Neck, 2008

INTRODUCTION Osteoradionecrosis (ORN) of the mandible is reported to occur in approximately 5% of the patients who undergo external beam radiation therapy for a head and neck malignancy. The management of ORN is based on the clinical stage at presentation and response to initial management. We utilized the Marx staging system and treatment algorithm to guide our decision making. In recent years, it has been our philosophy and that of others to perform a segmental mandibulectomy with an immediate reconstruction utilizing the transfer of vascularized bone for patients with Marx stage III disease. We feel that the placement of vascularized tissue into this unfavorable environment has greatly improved our outcomes in patients with advanced ORN.

Objectives/Hypothesis: The successful harvest and transplant of a fibular flap depends on many factors, including healthy inflow and outflow systems. A contraindication to harvesting a fibular flap is disease of the lower extremity arterial system; therefore, preoperative evaluation of the arterial system is routine. Preoperative evaluation of the venous system is not routine, unless there is clinical suspicion of venous disease. Methods: Retrospective chart review. Results: Two cases of occult deep venous thrombosis (DVT) were encountered intraoperatively resulting in nontransplantable flaps. Conclusions: This finding represents a serious concern, and we believe that venous imaging should be considered in patients with significant risk factors for harboring an occult DVT.

Case Report A 40 year-old gentleman presented to the otolaryngology office for evaluation of a left supraclavicular mass. Upon review of his history, it was found that the patient had noticed numbness of his arms, legs and trunk, which had developed 23 weeks previously. On physical examination the patient had no reflexes, tonic pupils, and orthostatic hypotension. Workup revealed that the patient had a sensorimotor polyneuropathy. He tested positive for serum anti-Hu antibodies. The patient underwent a left neck dissection including resection of the supraclavicular mass, and he was found to have a myxoid chondrosarcoma with metastases to several cervical lymph nodes. The tumor stained diffusely with anti-Hu antibodies. Since surgery, the patient has received intravenous immunoglobulin and Tacrolimus with slow progression of his neurologic disturbance.
