The high stakes of head and neck surgery following radiation and chemotherapy - An assessment of complications and survival.

OBJECTIVES: To investigate variables that predict medical and surgical complications in patients undergoing salvage surgery after primary organ-preserving therapy for head and neck cancer and to investigate the effect of complications on 5-year overall survival. MATERIALS AND METHODS: A retrospective study was conducted on patients undergoing salvage surgery after primary organ-preserving therapy for head and neck cancer at a tertiary institution from 2006 to 2011. Multivariable regression analysis was used to assess association between independent variables and medical and surgical complications. A Kaplan-Meier survival curve was plotted to assess effect of surgical and medical complications on 5-year overall survival. RESULTS: One hundred thirty-six patients undergoing salvage surgery after primary organ-preservation surgery met inclusion criteria. Surgical complications occurred in 68/136 (50.0%) of patients. After adjusting for confounders, young age and history of hypothyroidism were significant predictors of surgical complications (p < 0.05). Medical complications occurred in 37/136 (27.2%) of patients. After adjusting for confounders, older age and history of hepatic disease were significant predictors of having a medical complication (p < 0.05). Patients with no complications had better overall survival than patients with medical complications (p = 0.009). There was no difference in overall survival between patients without complications and patients with surgical complications only (p = 0.259). CONCLUSION: Risk factors for medical and surgical complications include history of hypothyroidism, liver disease, and age. Survival outcomes are not affected by surgical complications but are significantly affected by medical complications highlighting the importance of personalized patient care and medical co-management.

Irritant-Induced Paradoxical Vocal Fold Motion Disorder: Diagnosis and Management.

OBJECTIVES: To review our experience with the diagnosis and treatment of irritant-induced paradoxical vocal fold motion disorder (IPVFMD). STUDY DESIGN: Retrospective chart review. SETTING: Tertiary academic referral center. SUBJECTS AND METHODS: Thirty-four cases that met IPVFMD criteria and 76 cases of non-IPVFMD were selected from a database of patients with paradoxical vocal fold motion disorder-the diagnosis of which was made on the basis of flexible fiberoptic laryngoscopy and augmented by an odor challenge. Clinical charts were reviewed to document history of environmental allergies, pulmonary disease, gastroesophageal reflux, psychiatric disorder, fibromyalgia, tobacco use, alcohol use, dysphonia, cough, dysphagia, and treatment outcomes. RESULTS: There were no statistical differences between the IPVFMD and non-IPVFMD groups. Of the patients who were assigned and attended laryngeal control therapy, 13 (65%) reported improvement of symptoms. Symptom improvement increased to 100% in those patients who attended at least 2 laryngeal control therapy sessions. CONCLUSIONS: IPVFMD should be considered in patients presenting with respiratory symptoms after irritant exposure. Sensitivity of diagnosis can be improved via a standardized approach consisting of a careful history and physical examination, including laryngoscopy in the presence of triggers. Laryngeal control therapy is a well-tolerated and effective method of managing IPVFMD.

Paradoxical vocal fold motion disorder in the elite athlete: experience at a large division I university.

OBJECTIVES/HYPOTHESIS: To review our experience at a large division I university with the diagnosis and management of paradoxical vocal fold motion disorder (PVFMD) in elite athletes. STUDY DESIGN: A single institution retrospective review and cohort analysis. METHODS: All elite athletes (division I collegiate athletes, triathletes, and marathon runners) with a diagnosis of PVFMD were identified. All patients underwent flexible fiberoptic laryngoscopy (FFL) to confirm the diagnosis of PVFMD. The type of PVFMD therapy was identified and efficacy of treatment was graded based on symptom resolution. RESULTS: Forty-six consecutive athletes with PVFMD were identified. A total of 30/46 (65%) were division 1 collegiate athletes and 16/46 (35%) were triathletes or marathon runners. In comparison to a nonathlete PVFMD cohort, athletes were less likely to present with a history of reflux (P < 0.01), psychiatric diagnosis (P < 0.01), dysphonia (P < 0.01), cough (P = 0.02), or dysphagia (P < 0.01). The use of postexertion FFL provided additional diagnostic information in 11 (24%) patients. Laryngeal control therapy (LCT) was recommended for 45/46. A total of 36/45 attended at least one LCT session and 25 (69%) reported improvement of symptoms. Additionally, biofeedback, practice-observed therapy, and thyroarytenoid muscle botulinum toxin injection were required in three, two, and two patients, respectively. CONCLUSION: The addition of postexertion FFL improves the sensitivity to detect PVFMD in athletes. PVFMD in athletes responds well to LCT. However, biofeedback, practice-observed therapy, and botulinum toxin injection may be required for those patients with an inadequate response to therapy. LEVEL OF EVIDENCE: 4.

Clinicopathologic predictors of recurrence and overall survival in adenoid cystic carcinoma of the head and neck: a single institutional experience at a tertiary care center.

BACKGROUND: The purpose of this study was to determine factors that impact recurrence and long-term survival of head and neck adenoid cystic carcinoma (ACC). METHODS: We conducted a retrospective review of 87 patients with head and neck ACC who were evaluated between 1992 and 2009. Staining for Ki-67, p53, α-estrogen receptor (αER), and progesterone receptor (PR) was performed. RESULTS: Forty men (46%) and 47 women (54%) were included in this study. Median follow-up for patients was 98 months. Five-year recurrence-free and overall survival (OS) rates were 56% and 81%, respectively. Ki-67 and p53 expression was observed in 5 (6%) and 2 (2%) patients, respectively. αER and PR were all negative. The most important determinants of disease-free survival (DFS) were perineural invasion (PNI; p = .001) and female sex (p = .027). Disease site (major vs minor salivary gland) was the only predictor of worse OS on multivariate analysis. CONCLUSION: Perineural invasion, female sex, and disease site were the most consistent predictors of poor outcome in head and neck ACC.

Use of a novel receptor-targeted (CD206) radiotracer, 99mTc-tilmanocept, and SPECT/CT for sentinel lymph node detection in oral cavity squamous cell carcinoma: initial institutional report in an ongoing phase 3 study.

IMPORTANCE: Sentinel lymph node biopsy has been proposed as an alternative to up-front elective neck dissection (END) for determination of pathologic nodal status in patients undergoing surgical treatment for oral cavity squamous cell carcinoma (OSCC) with clinically negative neck (cN0). Sentinel lymph node biopsy using current standard tracer agents and imaging adjuncts such as radiolabeled sulfur-colloid and planar lymphoscintigraphy (LS), however, is associated with several drawbacks. OBJECTIVE: To assess the preliminary utility of technetium Tc 99m (99mTc)-tilmanocept, a novel molecular imaging agent for sentinel lymph node (SLN) mapping, in OSCC. DESIGN, SETTING, AND PARTICIPANTS: Prospective, nonrandomized, single-arm, part of an ongoing phase 3 clinical trial. Patients had previously untreated, clinically and radiographically node-negative OSCC (T1-4aN0M0) at an academic tertiary referral center. INTERVENTIONS: Patients received a single dose of 50 µg 99mTc-tilmanocept injected peritumorally followed by dynamic planar LS and fused single-photon emission computed tomography/computed tomography (SPECT/CT) prior to surgery. Surgical intervention consisted of excision of the primary tumor and radioguided SLN dissection followed by planned END. The excised lymph nodes (SLNs and non-SLNs) underwent histopathologic evaluation for presence of metastatic disease. MAIN OUTCOMES AND MEASURES: False-negative rate and negative predictive value of SLNB using 99mTc-tilmanocept and comparison of planar LS with SPECT/CT in SLN localization. RESULTS: Twelve of 20 patients (60%) had metastatic neck disease on pathologic examination. All 12 had at least 1 SLN positive for metastases. No patients had a positive END node who did not have at least 1 positive SLN. These data yield a false-negative rate of 0% and negative predictive value of 100% using 99mTc-tilmanocept in this setting. Dynamic planar LS and SPECT/CT revealed a mean (range) number of hot spots per patient of 2.9 (1-7) and 3.7 (1-12), respectively. Compared with planar LS, SPECT/CT identified additional putative SLNs in 11 of 20 cases (55%). CONCLUSIONS AND RELEVANCE: The high negative predictive value and low false-negative rate in identification of occult metastases shows 99mTc-tilmanocept to be a promising agent in SLN identification in patients with OSCC. Use of SPECT/CT improves preoperative SLN localization including delineation of SLN locations near the primary tumor when compared with planar LS imaging.

Transoral robotic surgery for oropharyngeal cancer: long-term quality of life and functional outcomes.

IMPORTANCE: Because treatment for oropharyngeal squamous cell carcinoma (OPSCC), especially in patients of older age, is associated with decreased patient quality of life (QOL) after surgery, demonstration of a less QOL-impairing treatment technique would improve patient satisfaction substantially. OBJECTIVE: To determine swallowing, speech, and QOL outcomes following transoral robotic surgery (TORS) for OPSCC. DESIGN, PARTICIPANTS, AND SETTING: This prospective cohort study of 81 patients with previously untreated OPSCC was conducted at a tertiary care academic comprehensive cancer center. INTERVENTIONS: Primary surgical resection via TORS and neck dissection as indicated. MAIN OUTCOMES AND MEASURES: Patients were asked to complete the Head and Neck Cancer Inventory (HNCI) preoperatively and at 3 weeks as well as 3, 6, and 12 months postoperatively. Swallowing ability was assessed by independence from a gastrostomy tube (G-tube). Clinicopathologic and follow-up data were also collected. RESULTS: Mean follow-up time was 22.7 months. The HNCI response rates at 3 weeks and 3, 6, and 12 months were 79%, 60%, 63%, and 67% respectively. There were overall declines in speech, eating, aesthetic, social, and overall QOL domains in the early postoperative periods. However, at 1 year post TORS, scores for aesthetic, social, and overall QOL remained high. Radiation therapy was negatively correlated with multiple QOL domains (P < .05 for all comparisons), while age older than 55 years correlated with lower speech and aesthetic scores (P < .05 for both). Human papillomavirus status did not correlate with any QOL domain. G-tube rates at 6 and 12 months were 24% and 9%, respectively. Greater extent of TORS (>1 oropharyngeal site resected) and age older than 55 years predicted the need for a G-tube at any point after TORS (P < .05 for both). CONCLUSIONS AND RELEVANCE: Patients with OPSCC treated with TORS maintain a high QOL at 1 year after surgery. Adjuvant treatment and older age tend to decrease QOL. Patients meeting these criteria should be counseled appropriately.

Exercise-induced paradoxical vocal fold motion disorder: diagnosis and management.

OBJECTIVES/HYPOTHESIS: To review our experience with the diagnosis and treatment of exercise-induced paradoxical vocal fold motion disorder (EPVFMD). STUDY DESIGN: Single-institution retrospective review and cohort analysis. METHODS: A single-institution retrospective review was performed identifying patients with paradoxical vocal fold motion disorder (PVFMD). Patients with isolated exercise-induced dyspnea were selected for further review. Flexible fiberoptic laryngoscopy (FFL) performed on these patients were reviewed with regard to presence of laryngeal pathology as well as the presence of PVFMD at rest and/or with exertion. The type of therapy was reviewed. Symptom outcomes were graded as complete resolution, improvement, or unchanged following therapy. RESULTS: There were 758 patients who were identified with PVFMD. A total of 104 patients demonstrated symptoms of PVFMD that were only exercise related (EPVFMD). There were 93/104 (89%) patients who underwent a pre- and post-trigger FFL. Of these, 48/93 (52%) patients had no evidence of PVFMD on initial FFL. After subjecting these patients to exertion, 83/93 (89%) had evidence of PVFMD on postexertion FFL, and 39/93 (42%) patients had evidence of PVFMD on both pre-exertion and postexertion FFL. There were 87/104 (84%) patients who had evidence of laryngeal edema, and 23/104 (23%) had one or more laryngeal lesion on examination. A total of 67 patients were enrolled in laryngeal control therapy and attended at least one session, with 48/67 (72%) demonstrating improvement or complete resolution of their symptoms. CONCLUSIONS: The diagnosis of EPVFMD is augmented with the addition of provocation testing. Findings of PVFMD can be identified at rest when asymptomatic. Laryngeal control therapy is an effective treatment for EPVFMD.

Primary intraosseous cavernous hemangioma of the zygoma: a case report and literature review.

Intraosseous hemangiomas are rare. We report the case of a 47-year-old man who presented with a gradually enlarging left zygomatic mass that had caused pain, deformity, and superficial soft-tissue swelling. Computed tomography revealed a well-circumscribed 2.0 × 2.5-cm mass with a ground-glass matrix in the left zygoma. Following surgical excision, the patient's symptoms resolved. Findings on pathologic examination of the excised tissue were consistent with an intraosseous cavernous hemangioma. We describe the features of this rare case, we discuss the pertinent radiologic features and pathophysiology of intraosseous hemangiomas, and we review the available literature.

Quality-of-life outcomes in transoral robotic surgery.

OBJECTIVE: To report long-term, health-related quality-of-life (HRQOL) outcomes in patients treated with transoral robotic surgery (TORS). STUDY DESIGN: Prospective, longitudinal, clinical study on functional and HRQOL outcomes in TORS. SETTING: University tertiary care facility. SUBJECTS AND METHODS: Patients who underwent TORS were asked to complete a Head and Neck Cancer Inventory before treatment and at 3 weeks and 3, 6, and 12 months postoperatively. Demographic, clinicopathological, and follow-up data were collected. RESULTS: Sixty-four patients who underwent TORS were enrolled. A total of 113 TORS procedures were performed. The mean follow-up time was 16.3 ± 7.49 months. The HRQOL was assessed at 3 weeks and at 3, 6, and 12 months, with a response rate of 78%, 44%, 41%, and 28%, respectively. TORS was performed most frequently for squamous cell carcinoma (88%). There was a decrease from baseline in the speech, eating, aesthetic, social, and overall QOL domains immediately after treatment. At the 1-year follow-up, the HRQOL scores in the aesthetic, social, and overall QOL domains were in the high domain. Patients with malignant lesions had significantly lower postoperative HRQOL scores in the speech, eating, social, and overall QOL domains (P < .05). Patients who underwent adjuvant radiation therapy or chemotherapy and radiation therapy had lower postoperative scores in the eating, social, and overall QOL domains (P < .05). CONCLUSION: The preliminary data show that patients who undergo TORS for malignancies and receive adjuvant therapy tend to have lower HRQOL outcomes. TORS is a promising, minimally invasive, endoscopic alternative surgical treatment of laryngopharyngeal tumors.
