Intractable Aspiration Treated With Laryngectomy After SLAD-R Surgery: A Case Report. Laryngoscope 2024. [PMID: 38738808 DOI: 10.1002/lary.31510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 04/29/2024] [Accepted: 05/02/2024] [Indexed: 05/14/2024]
Abstract
A variety of surgical treatment options exist for adductor spasmodic dysphonia (ADSD) with selective adductor recurrent laryngeal nerve denervation and reinnervation (SLAD-R) being one of the more popular. We present a case of bilateral vocal fold paralysis (BVFP) for SLAD-R resulting in the need for total laryngectomy. We suggest BVFP is more common than reported and that we all must insure optimal long term follow up of our surgical patients. Laryngoscope, 2024.

Abstract
This report presents a case of worsening obstructive sleep apnea (OSA) post-chemoradiation therapy that improved significantly after placement of a hypoglossal nerve stimulator. The patient was a 66-year-old male, diagnosed with head and neck cancer, who experienced exacerbation of OSA after receiving chemoradiation. A hypoglossal nerve stimulator was placed, with minimal complications. The patient showed a significant improvement in OSA as exhibited by the reduction in apnea-hypopnea index. Hypoglossal nerve stimulator placement appears to be a potential treatment option for induced or worsened OSA, which is a known complication of head and neck cancer treatment. When considering treatment options, upper airway stimulation is indeed a possible method in patients who meet the recommended guideline criteria.

Abstract
Adenosquamous Carcinoma is a rare, aggresssive variant of squamous cell carcinoma that may HPV-driven in the oropharynx. Although it is reported to behave similar to HPV-related squamous cell carcinoma, the literature is very limited for this disease. We present a case of early T and N stage HPV + adenosquamous carcinoma of the tonsil that metastasized immediately following surgery and adjuvant therapy despite only having microscopic nodal burden. Circulating tumor DNA (ctDNA) was instrumental in recognizing and salvaging metastatic disease early with radiation.

Inhibitors of the CD73-adenosinergic checkpoint as promising combinatory agents for conventional and advanced cancer immunotherapy. Front Immunol 2023; 14:1212209. [PMID: 37435071 PMCID: PMC10330720 DOI: 10.3389/fimmu.2023.1212209] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 05/31/2023] [Indexed: 07/13/2023] Open
Abstract
The cell surface enzyme CD73 is increasingly appreciated as a pivotal non-redundant immune checkpoint (IC) in addition to PD-1/PD-L1 and CTLA-4. CD73 produces extracellular adenosine (eADO), which not only inhibits antitumor T cell activity via the adenosine receptor (AR) A2AR, but also enhances the immune inhibitory function of cancer-associated fibroblasts and myeloid cells via A2BR. Preclinical studies show that inhibition of the CD73-adenosinergic pathway in experimental models of many solid tumors either as a monotherapy or, more effectively, in combination with PD-1/PD-L1 or CTLA-4 IC blockades, improves antitumor immunity and tumor control. Consequently, approximately 50 ongoing phase I/II clinical trials targeting the CD73-adenosinergic IC are currently listed on https://clinicaltrials.gov. Most of the listed trials employ CD73 inhibitors or anti-CD73 antibodies alone, in combination with A2AR antagonists, and/or with PD-1/PD-L1 blockade. Recent evidence suggests that the distribution of CD73, A2AR and A2BR in tumor microenvironments (TME) is heterogeneous, and this distribution affects CD73-adenosinergic IC function. The new insights have implications for the optimally effective, carefully tailored approaches to therapeutic targeting of this essential IC. In the mini-review, we briefly discuss the cellular and molecular mechanisms of CD73/eADO-mediated immunosuppression during tumor progression and therapy in the spatial context of the TME. We include preclinical data regarding therapeutic CD73-eADO blockade in tumor models as well as available clinical data from completed trials that targeted CD73-adenosinergic IC with or without PD-1/PD-L1 inhibitors and discuss factors that are potentially important for optimal therapeutic outcomes in cancer patients.

Abstract
We aimed to retrospectively determine if initial staging 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/ CT) can predict overall survival (OS) in oral cavity squamous cell carcinoma (OCSCC), which is currently a source of ongoing controversy in the literature. Forty-six consecutive patients with nonmetastatic (Stage M0) OCSCC had 18F-FDG PET/CT prior to definitive surgical treatment followed by observation or adjuvant treatment at our institution between 2006 and 2012. The median follow-up time was 18 months (range 0.1–76 months). Univariate and multivariate analysis were used to determine the ability of imaging, pathologic, and demographic factors to predict OS. 18F-FDG PET/CT parameters were standardized uptake value (SUV) maximum and mean, metabolic tumor volume, and total lesional glycolysis (TLG) of primary tumor and regional nodes. Significant predictors of OS in the multivariate analysis were primary tumor SUV mean, nodal TLG, and age. Two-year OS of patients with primary tumor SUV mean below and above the median of 6.26 was 68% and estimated 28%, respectively. Two-year OS of patients with nodal TLG below and above median of 7.9 was 69% and 34%, respectively. Two-year OS of patients younger and older than median age of 57 was 60% and 43%, respectively. Our results suggest that 18F-FDG PET/CT may be a valuable addition to multifactorial models predicting outcome for OCSCC. Thus, continued research aiming to incorporate 18F-FDG PET/CT parameters in risk-stratification algorithms for OCSCC is warranted and should be conducted using more standardized prognostic models driven by a specific clinical question.

Abstract
OBJECTIVE The incidence of occult metastasis (OM) in laryngeal squamous cell carcinoma (SCC) is still widely debated. In this systematic review, we aim to determine the rate of OM in laryngeal SCC, its impact on recurrence, and the role of elective neck dissection (END) in the management of the clinically negative neck. METHODS A systematic review of the English-language literature in Web of Science, PubMed, MEDLINE, and Cochrane Library databases on occult metastasis in laryngeal SCC from 1977 to 2018 was conducted. Studies evaluating occult metastasis (OM) in patients with laryngeal SCC with clinically negative necks undergoing surgery were included. Studies evaluating other head and neck subsites, clinically node positive, and salvage patients were excluded. RESULTS Twenty-one articles with a total of 5630 patients were included. The overall rate of OM was 20.5% and was 23% and 12.2% in supraglottic and glottic tumors, respectively. The OM rate in T1-T2 tumors was 13% and 25% in T3-T4 tumors. T3-T4 tumors had significantly greater odds of developing OM compared to T1-T2 tumors (Odds Ratio [OR] = 2.61, 95% Confidence Interval [CI] = 1.92-3.55, P < .00001). Patients with OM were more likely to develop distant metastasis (OR = 5.65, 95% CI = 3.36-9.51, P < .00001). CONCLUSIONS Patients with advanced T-stage laryngeal SCC should undergo elective neck treatment. More aggressive treatment for patients with history of OM should be considered due to the risk of subsequent regional and distant metastasis. LEVEL OF EVIDENCE II.

Abstract
Patients with head and neck cancer represent a vulnerable population at particular risk of opioid dependence due to frequent histories of substance abuse, requirement of extensive surgery, and the synergistic toxicity of multimodal therapy. Regional anesthetic techniques have been used by other surgical disciplines to facilitate early recovery after surgery and decrease postoperative patient narcotic requirements. This pilot study investigates the efficacy of a preoperative regional analgesia using stellate ganglion block in lateralized head and neck cancer surgery. From our early results, stellate ganglion blockade may hold promise as an effective preoperative intervention for controlling early postoperative pain, lessening narcotic requirements, and improving quality of life.

Abstract
Background: Salivary clear cell carcinoma is an uncommon, low-grade malignancy for which limited data describing predictive clinicopathologic factors and treatment outcomes exist because of rarity. Methods: The authors queried the Surveillance, Epidemiology, and End Results database from 1982 to 2014. Multivariate Cox and Kaplan-Meier analyses were performed to determine disease-specific survival (DSS) and predictive clinicopathologic factors. Results: One hundred ninety-eight patients with salivary clear cell carcinoma were included. Overall incidence was 0.011 per 100 000 individuals, with no significant annual percentage change across years (−0.93%, P = .632). Five-, 10-, and 20-year DSS rates were 81.3% (n = 117), 69.6% (n = 94), and 55.3% (n = 68), respectively. Men (hazard ratio, 4.74; P = .0087) and patients with regional (hazard ratio, 5.59; P = .018) or distant (hazard ratio, 8.9; P = .01) metastases carried a worse prognosis. Five-year DSS was greater in patients with localized disease (96.36%, P < .0001) than those with regional or distant metastases. Treatment with surgery alone had better 10-year DSS (86.3%) compared with treatment with combination radiation and surgery (57.6%) or radiation monotherapy (18.75%, P < .0001). Conclusions: Salivary clear cell carcinoma carries an overall good prognosis. Patients with localized disease and those treated with surgery alone have more favorable prognoses. Male patients and those with regional or distant metastatic disease at time of presentation carry a worse prognosis. Level of Evidence: N/A

Abstract
Objectives/Hypothesis Salivary gland nasopharynx cancers (SGNPCs) are rare malignancies with few cases discussed in the literature. This study represents the largest cohort of SGNPC to date. Study Design Retrospective population-based analysis. Methods The Surveillance, Epidemiology, and End Results registry from 1973 to 2015 was utilized to extract 383 cases of SGNPC. Data were analyzed for demographic characteristics, incidence, clinicopathologic traits, and outcome prognosticators. Results White female patients aged >40 years were most commonly affected. The incidence was measured as 0.019 per 100,000 people. The majority of tumors presented at advanced stages (stage III/IV, 60.8%). Adenoid cystic carcinoma, adenocarcinoma, and mucoepidermoid carcinoma were the most commonly encountered histologies (43.1%, 31.6%, 13.3%, respectively). Cervical node involvement and distant metastasis were measured at 23% and 11.9%, respectively. Mucoepidermoid carcinomas presented with the best disease-specific survival at 5 and 10 years. Asian ethnicity, age <80 years, and earlier American Joint Committee on Cancer stages were positive prognostic factors. The inclusion of surgical therapy improved 5-year outcomes among the most common histologies, except for mucoepidermoid carcinoma. Conclusions Salivary gland nasopharyngeal cancer represents a group of rare histologies with similar outcomes as squamous cell carcinomas. However, prognosis is primarily dependent on histologic subtype, race, age, and American Joint Committee on Cancer stage.

Abstract
Skull base pseudotumors, or tumefactive fibroinflammatory lesions (TFIL), are tumors characterized by local destruction with benign histopathology. Treatment includes surgery and steroids with varying degrees of symptom relief. A 45-year-old female presented with right otorrhea and middle ear effusion, which progressed to CN V3 pain/numbness, trismus, headache, and autophony. MRI showed a diffuse infiltrating mass in the right infratemporal region involving the trigeminal ganglion. Biopsy revealed benign fibromuscular and adipose tissue with lymphoplasmacytic infiltrate, giving a diagnosis of TFIL. Resection would be very difficult given tumor location. Initial treatment included an extended course of steroids without response, and interval disease progression. Two courses of rituximab 375 mg/m2 weekly × 4 given 3 months apart were then completed with excellent tolerance. With sixteen months following induction, the patient reports minimal symptoms with radiographic findings confirming continued disease regression. Rituximab is a potential treatment option for patients with TFIL without response to steroids.

Abstract
BACKGROUND A lymph node yield (LNY) over 20 is considered a quality metric for lateral neck dissection to ensure an oncologic representative sample. Anecdotally, however, LNY in patients undergoing neck dissection after radiation therapy (RT) is lower due to atrophy and fibrosis. OBJECTIVE To determine whether preoperative RT decreases LNY in patients with laryngeal cancers undergoing surgery. METHODS Medical record database was queried for patients presenting between 2006 and 2015 with laryngeal cancer. Tabulation was made for location (glottic/supraglottic), stage, and side for the total number of lymph nodes between primary surgery and RT (salvage surgery) groups. Descriptive analysis and a paired Student t test were used for statistical analysis. RESULTS Fifty-nine patients were included in the study for a total of 98 neck dissections. Twenty-six (44%) patients had primary surgery, and 33 (56%) patients had salvage surgery. The mean left and right total LNY in the salvage surgery group was 27.6 and 29.5, respectively, and 32.2 and 33.7 for the primary surgery group. A difference of 4.5 (left) and 4.3 (right) in LNY between the salvage surgery and primary surgery group was found. A Student t test showed no statistically significant difference in LNY between both groups when analyzed per site (glottic and supraglottic), side, and stage (III-IV). CONCLUSION Although patients with prior RT had a lower mean of LNY, our results did not demonstrate a statistically significant difference. Further studies with a larger number of patients are recommended.

Abstract
Malignant conversion of sinonasal inverted papilloma (SNIP) occurs in approximately ten percent of cases. These tumors are classically described as locally destructive, but without metastatic potential. Only four cases of malignant conversion with cervical nodal metastases have been described in the English literature. We present the rare case of a 61-year-old Caucasian male with a nasopharyngeal recurrence of malignant SNIP with cervical and retropharyngeal nodal metastases. The patient underwent endoscopic transpterygoid with nasoseptal flap reconstruction, followed by staged bilateral and retropharyngeal node dissection. Histopathology of the specimens demonstrated poorly differentiated invasive nonkeratinizing squamous cell carcinoma with inverted-type features. Three months after surgery, the patient suffered from C1-C2 fractures consistent with osteoradionecrosis and expired. Although the rate of malignant conversion of SNIP is low, this case highlights the need for aggressive, definitive treatment and surveillance.

Abstract
The objective of our study is to assess the impact of equivocal or positive positron emission tomography combined with low-dose noncontrast computed tomography (PET/CT) findings in the chest on treatment for head and neck cancer (HNC). We reviewed charts of patients presented at Augusta University's Head and Neck Tumor Board (AUTB) between 2013 and 2016 with the following exclusion criteria: <18 years, Veterans Affairs patients, those with incomplete data, and those without a history of head and neck squamous cell carcinoma. The lung/thorax sections of the radiologists' PET/CT reports were graded as "Positive, Equivocal, or Negative" for chest metastases. Patients who underwent workup for suspected chest metastases were assessed for treatment delays, changes in treatment plans, and complications. In addition, we evaluated the time between AUTB presentation and peri-treatment PET/CT to primary treatment initiation were calculated between groups. There was a total of 363 patients with PET/CT prior to treatment, the read was "Negative" in 71.3% (n = 259), "Equivocal" in 20.9% (n = 76), and "Positive" in 5.8% (n = 21). Of 272 patients with complete treatment data, 22 underwent workup for suspected chest metastases. Mean time from PET/CT to treatment initiation was 27.5 days without workup and 64.9 days with workup ( P < .0001), and from AUTB presentation was 29.1 days without workup and 62.5 days with workup ( P < .0001). Five (19.2%) patients experienced a complication from workup. Twenty (76.9%) patients had no changes in their treatment plan after workup. In conclusion, our results for potential chest metastases on PET/CT in patients with HNC are often not clear-cut. Workup of suspected chest metastasis based on PET/CT findings significantly delays primary treatment initiation and may cause serious complications.

Abstract
Although the field of otolaryngology has experienced a decline in the number of applicants to our residency programs, otolaryngology remains a highly competitive field with an extremely strong applicant pool. Many highly qualified candidates cannot obtain a position in our field each year, and many of these candidates choose to reapply the next year. Data are lacking regarding reapplicants' success rate and the best gap year employment and training options for these reapplicants. Reapplicants were studied prospectively via a two-stage survey during the 2014-2015 and 2015-2016 application cycles. Success rates for the overall group were compared to those from published data, and success rates between subgroups were also compared. First-time reapplicants in the study performed extremely well. Their match rate (19/22) was not significantly different from that of traditional otolaryngology applicants (551/619, p = 0.73) and was significantly higher than that of nontraditional applicants not in our cohort (23/62, p < 0.001). No significant difference was found between applicants by employment/training activities, with both researchers (11/12) and surgical interns (8/10, p = 0.57) performing well. Predictors of reapplicant success could not be assessed because only 3 reapplicants in the cohort were unsuccessful. First-time otolaryngology reapplicants remain a highly competitive group of applicants to our field, regardless of employment/training activities undertaken after graduating medical school.

Abstract
OBJECTIVES Basaloid nasopharyngeal carcinoma (BNPC) is an extremely rare malignancy with a paucity of cases reported in the literature. This analysis represents the largest cohort of BNPC to date. STUDY DESIGN Retrospective population-based analysis. METHODS The Surveillance, Epidemiology, and End Results registry from 2001 to 2015 was utilized to extract a total of 82 cases of BNPC. Data were analyzed for incidence trends, demographic, and tumor characteristics, as well as potential outcome prognosticators. RESULTS White male patients between the ages of 40 to 79 years were most commonly affected. The incidence was measured at 0.06 per 100 thousand people. The majority of tumors were considered high grade (grade III/IV; 92.2%). At presentation, patients were most commonly advanced stage (American Joint Committee on Cancer [AJCC] stage IV) at 29.3%, followed by AJCC stages II and III (20.7%, respectively). T2 tumors were most common at 28.8%. Cervical node involvement and distant metastasis were measured at 53.7% and 10.4%, respectively. One-year, 5-year, and 10-year disease-specific survival was 87.7%, 60.7%, and 29.8%, respectively. No prognostic factors were identified in this study. CONCLUSION Basaloid squamous cell carcinoma represents a histologic subtype of nasopharyngeal carcinoma with excellent short-term outcomes but poor survival at 10 years when compared to conventional squamous cell carcinomas.

Abstract
The 1990s saw an increased use of chemoradiotherapy protocols, commonly referred to as organ-sparing therapy, for the treatment of oropharyngeal cancer after the Groupe d'Oncologie Radiothérapie Tête et Cou trial. Since that time, human papillomavirus-associated oropharyngeal squamous cell carcinoma has been identified as a unique disease, with improved survival regardless of treatment modality. The improved outcomes of this population has led to re-evaluation of treatment paradigms in the past decade, with a desire to spare young, human papillomavirus-positive patients the treatment-related toxicities of chemoradiotherapy and to use new minimally invasive surgical techniques to improve outcomes. Numerous retrospective and prospective studies have investigated the role of surgery in treatment of oropharyngeal carcinoma and have demonstrated equivalent oncologic outcomes and improved functional outcomes compared with chemoradiotherapy protocols. Ongoing and future clinical trials may help delineate the role of surgery in the future.

Abstract
BACKGROUND Chondrosarcoma is a rare tumor of the head and neck. Because of the limited clinical data, no studies have conducted a thorough comparison between head and neck chondrosarcomas and those arising at other body sites. METHODS Using the Surveillance, Epidemiology, and End Results (SEER) database, we compared 682 patients with chondrosarcomas of the head and neck with 4757 patients with non-head and neck chondrosarcomas, evaluating disease-specific survival (DSS) and overall survival (OS) based on tumor location, histology, grade, stage, and treatment. RESULTS Head and neck chondrosarcomas displayed a lower grade (p < .001) and stage (p < .0001) compared with other chondrosarcomas. Overall, chondrosarcomas of the head and neck had significantly higher DSS and OS than non-head and neck chondrosarcomas (p < .001). CONCLUSION Chondrosarcomas of the head and neck display a lower grade and stage compared with other chondrosarcomas. DSS and OS were significantly greater for chondrosarcomas of the head and neck. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1359-1366, 2016.

Abstract
OBJECTIVE This study describes the potential application of intraoperative ultrasound imaging during transoral robotic surgery (TORS). METHODS Ultrasound imaging was performed during transoral robotic resection of oropharyngeal tumors in 10 patients at a tertiary academic center. Ultrasound imaging was utilized to identify large-caliber vessels adjacent to the surgical site. Measurements were also taken on the ultrasound of tumor thickness to determine the deep margin. Following resection, the tumor was sectioned, and a gross measurement of the tumor thickness was obtained. RESULTS Intraoperative ultrasound use led to the identification of larger-caliber blood vessels within the operative field prior to encountering them visually. Ultrasound could also aid in defining deep tumor margins; the tumor thickness measured via ultrasound was found to be accurate within 1 to 2 mm of the grossly measured tumor thickness. This allowed for focused, careful dissection to protect and avoid blood vessels during dissection as well as improved tumor resection. CONCLUSIONS The use of intraoperative ultrasound provides additional information to the head and neck surgeon during TORS. This may be used to identify blood vessels and assess tumor margins, thereby improving the safety and efficacy of TORS.

Abstract
OBJECTIVE To determine whether the human papillomavirus (HPV) status of head and neck squamous cell carcinomas (HNSCCs) can be reliably predicted based on sociodemographic and disease characteristics alone. DESIGN A retrospective medical chart review of clinical and pathologic features. SETTING Tertiary academic medical center. PATIENTS We studied patients treated for HNSCC who were tested for markers of HPV or had tissue available for testing between 2006 and 2010. MAIN OUTCOME MEASURES Four otolaryngology-head and neck surgery trainees were given the database of patient clinical and pathologic features and asked to predict the HPV status for each patient. The trainees' responses were scored for accuracy, positive and negative predictive value, and interrater agreement. Multiple linear regression analyses were performed to determine predictors of HPV positivity. RESULTS A total of 174 patients meeting inclusion criteria were identified, 95 of whom were determined to have HPV-positive tumor tissue. Residents were able to accurately predict HPV status in 110 to 125 patients (63%-72%), with positive predictive values of 76% to 84% and negative predictive values of 61% to 69%. The only variables significantly related to HPV status were male sex (P = .01) and oropharyngeal subsite (P = .02). Only 4 patients had a "typical" HPV-positive profile. CONCLUSIONS Knowledge of cancer stage, primary site, basaloid features, tumor differentiation, and presence of cystic neck disease and patient age, race, and smoking status did not allow accurate predictions of HPV status in many patients. Clinical testing of tumor tissue remains essential for a diagnosis of HPV-positive disease.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of transoral robotic surgery (TORS) for the diagnosis and treatment of cervical unknown primary squamous cell carcinoma (CUP). STUDY DESIGN Case series with chart review. SETTING Tertiary academic hospital. SUBJECTS AND METHODS A retrospective chart review was performed on patients with new occult primary squamous cell carcinoma of the head and neck with nondiagnostic imaging and/or endoscopy who were treated with TORS at a tertiary hospital between 2009 and 2012. Direct costs were obtained from the hospital's billing system, and national data were used for inpatient hospital costs and physician fees. The proportion of tumors found in 3 strategies was used as effectiveness to calculate the incremental cost-effectiveness ratio. RESULTS In total, 206 head and neck robotic cases were performed at our institution between December 2009 and December 2012. Three surgeons performed TORS on 22 patients for occult primary squamous cell carcinoma. The primary tumor was located in 19 of 22 patients (86.4%). The incremental cost-effectiveness ratio for sequential and simultaneous examination under anesthesia with tonsillectomy (EUA) and TORS base of tongue resection was $8619 and $5774 per additional primary identified, respectively. CONCLUSION Sequential EUA followed by TORS is associated with an incremental cost-effectiveness ratio of $8619 compared with traditional EUA alone. Bilateral base of tongue resection should be considered in the workup of these patients, particularly if the palatine tonsils have already been removed.

Abstract
OBJECTIVE Cancer of an unknown primary (CUP) squamous cell carcinoma metastatic to cervical lymph nodes is a challenging problem for the treating physician. Our aim is to determine if identification of the primary tumor is associated with improved oncologic outcomes and/or tumor characteristics including human papilloma virus (HPV) status. STUDY DESIGN Retrospective, matched-pairs analysis contrasting 2 cohorts based upon discovery of primary lesion. SETTING Tertiary teaching hospital. SUBJECTS AND METHODS Records of 136 patients initially diagnosed as carcinoma of unknown primary were retrospectively reviewed (1980-2010) and divided into 2 cohorts based on discovery of the primary lesion. Primary outcome measures were overall survival and time to recurrence according to Kaplan-Meier analysis. A nested subset of 22 patients in which the primary was discovered were matched to 22 patients remaining undiscovered according to nodal stage and age. RESULTS Discovered lesions were more likely to exhibit HPV positivity (P < .001). Matched-pairs analyses demonstrated that discovery of the primary was associated with better overall survival (HR = 0.125; 95% confidence interval [CI], 0.019-0.822; P = .030). Discovery of the primary was associated with improved cause-specific survival (HR = 0.142; 95% CI, 0.021-0.93; P = .0418) and disease-free survival (HR = 0.25; 95% CI, 0.069-0.91; P = .03). CONCLUSION HPV positivity is associated with discovery of the primary tumor. Discovery of the primary lesion is associated with improved overall survival, cause-specific survival, and disease-free survival in patients initially presenting as CUP in matched-pair and cohort comparison analyses.

Abstract
BACKGROUND Cosmesis is of increasing importance to the otolaryngology patient population. This is the first report of clinical outcomes of robot-assisted neck dissection by North American groups. METHODS This is a retrospective case-control study. Cases included three patients who underwent isolated, ipsilateral robot-assisted neck dissection. Operative time, estimated blood loss, lymph node retrieval, total drainage, hospital stay and complications from this group were compared against the outcomes of six consecutive patients who underwent conventional neck dissection. RESULTS Operative times were longer in robot-assisted neck dissection (mean 234 min) compared with the conventional neck dissection (mean 110 min). There were no significant differences between the two groups in other outcomes. CONCLUSIONS Robot-assisted selective neck dissection of levels II-IV is feasible through a modified facelift incision. Our initial data suggest that this procedure is surgically sound. It should be applied by experienced surgeons who wish to avoid a cervical incision.

Abstract
OBJECTIVES/HYPOTHESIS To identify patient factors associated with outcomes in critically ill obese patients requiring tracheotomy. STUDY DESIGN Single-institution, retrospective cohort study. METHODS Charts were reviewed for inpatients admitted to an intensive care unit from 2007 to 2010 with International Classification of Diseases, 9th Revision codes of obesity or morbid obesity and tracheotomy. Variables collected in the dataset include subject age, ethnicity, gender, body mass index, tracheotomy type, patient outcome, chief diagnosis, and medical comorbid conditions. The primary outcomes of interest were tracheotomy type and patient outcome at the time of hospital discharge. Logistic regression models were developed for the probability of each patient outcome using univariate and multivariate models. RESULTS One hundred two patients met inclusion criteria. The most common outcome was tracheostomy dependence (49%). Increased mortality was independently significantly associated with pulmonary hypertension (P = .019) and African American ethnicity (P = .045). Increased tracheostomy dependence was significantly associated with obstructive sleep apnea (P = .030). Increased decannulation was significantly associated with percutaneous tracheotomy (P = .016) and Caucasian ethnicity (P < .001). CONCLUSIONS Obese patients in the intensive care unit who undergo tracheotomy have a high likelihood of remaining tracheostomy dependent at the time of discharge from the hospital. The factors most commonly found to be significantly associated with poor outcomes were open tracheotomy, African American ethnicity, obstructive sleep apnea, and pulmonary hypertension.

Abstract
OPINION STATEMENT Well differentiated thyroid carcinoma (WDTC) is a relatively common malignancy accounting for an estimated 37,000 thousand cases in the United States in 2009 [1]. WDTC also has a generally high 5 year survival rate that correlates with age. Papillary thyroid carcinoma (PTC) greater than 1 cm is best managed by total thyroidectomy. Thyroid lobectomy and isthmusectomy may be adequate for unifocal PTC less than 1 cm in patients without negative prognostic factors. Central compartment and possible lateral neck dissections should be performed when nodal metastases are present in the respective nodal basins. Post-operatively, radioactive iodine ablation with (131)I followed by thyroid stimulating hormone (TSH) suppression is indicated in certain patients to improve locoregional control and reduce recurrence.

Minimally invasive video-assisted thyroidectomy versus conventional thyroidectomy: a cost-effective analysis. Otolaryngol Head Neck Surg 2010; 143:789-94. [PMID: 21109079 DOI: 10.1016/j.otohns.2010.08.002] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2010] [Revised: 07/07/2010] [Accepted: 08/10/2010] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To compare the cost of minimally invasive video-assisted thyroidectomy (MIVAT) with conventional thyroidectomy. STUDY DESIGN A cost-effectiveness study and chart review. SETTING Academic university hospital. SUBJECTS AND METHODS Pediatric and adult patients referred to the Department of Otolaryngology-Head and Neck Surgery for suspicious thyroid nodules, goiters, or known carcinomas. A tertiary care hospital's billing department was queried for all hemithyroidectomies and total thyroidectomies completed by the Department of Otolaryngology-Head and Neck Surgery between January 5, 2006, and November 1, 2007. The charges, including surgery, hospital, pathology, and anesthesia, for minimally invasive video-assisted thyroidectomy (MIVAT) and traditional or minimally invasive open thyroidectomies meeting MIVAT inclusion criteria were then reviewed retrospectively and compared statistically. RESULTS A total of 185 thyroidectomies were performed, 50.3 percent of which met criteria for MIVAT. Length of stay (days) was significantly shorter for patients undergoing MIVAT hemithyroidectomy (mean difference -0.8; 95% confidence interval [95% CI] -1.08 to -0.52) and not significantly different between groups for total thyroidectomy (mean difference 0.1; 95% CI -0.36 to 0.56). Mean anesthesia cost (U.S.$) was similar between groups for hemi- and total thyroidectomies. MIVAT mean pathology cost was significantly less than open thyroidectomy for hemithyroidectomy (mean difference -89.9; 95% CI -179.01 to -0.79) and approached significance for total thyroidectomy. There was no significant difference in hospital cost and total cost for hemithyroidectomy and total thyroidectomy. CONCLUSION In a group of matched cohorts, the cost of MIVAT appears to be equal to that of open thyroidectomy.
