Anxiety symptoms predict head and neck cancer survival: Exploring mediation by systemic inflammation and tumor response to treatment.

BACKGROUND: Head and neck cancers (HNC) are associated with high rates of anxiety. Anxiety has been linked to biological pathways implicated in cancer progression, though little is known about its effects on overall survival. We hypothesized that higher pretreatment anxiety levels in patients with HNC would predict poorer 2-year overall survival and expected this relationship to be mediated by both systemic inflammation and tumor response to treatment. METHODS: Patients (N = 394) reported anxiety symptomatology via the GAD-7 at treatment planning. Pre-treatment hematology workup provided an index of systemic inflammation (SII; N = 292). Clinical data review yielded tumor response and overall survival. Logistic and multiple regressions and Cox proportional hazard models tested hypothesized relationships. RESULTS: Higher pretreatment anxiety levels were significantly associated with poorer 2-year survival (hazard ratio [HR], 1.039; 95% confidence interval [CI], 1.014-1.066, p = 0.002). The association between anxiety and SII was not significant, though anxiety was associated with poorer tumor response (odds ratio [OR], 1.033; 95% CI, 1.001-1.066, p = 0.043). Tumor response fully mediated the relationship between anxiety symptoms and 2-year survival (HR, 9.290, 95% CI, 6.152-14.031, p < 0.001). CONCLUSIONS: Anxiety was associated with overall survival. Tumor response, but not systemic inflammation, emerged as a potential biological pathway mediating this effect. Screening for anxiety may be beneficial to help prospectively address these concerns and ameliorate potentially detrimental impact on clinically meaningful cancer outcomes.

Surface mould brachytherapy in oral and oropharyngeal cancers.

INTRODUCTION: There are insufficient data on surface mold brachytherapy (SMB) in treating oral cancers. We reviewed our institutional experience to investigate the efficacy and toxicity of this treatment modality. MATERIAL AND METHODS: We retrospectively reviewed all the patients treated between 1989 and 2018 with high-dose-rate iridium-192 SMB for oral and oropharyngeal squamous cell carcinomas at our institution. Surface mold brachytherapy was delivered via an acrylic surface mold with 1-5 inserted catheters spaced 1 cm apart fabricated by our dental oncologist. The Kaplan-Meier product estimator was used to assess local control (LC), locoregional control (LRC), distant metastasis-free survival (DMFS), and overall survival (OS). Cox proportional hazards regression analysis was used to assess the relationship of various variables and patient outcomes. RESULTS: Eighteen patients met the inclusion criteria and were evaluated. Indications for treatment were primary tumor (n = 13), local recurrence (2), locoregional recurrence (1), and oligometastatic disease (1). Ten patients received SMB alone and 8 received external beam radiotherapy with an SMB boost. The acute toxicity outcomes were as follows: no toxicity (n = 1), grade 1 (7), grade 2 (9), and grade 3 (1). Late effects were rare, only occurring in 3 patients. The one- and two-year LC were 81% and 68%, LRC 77% and 64%, DMFS 81% and 81%, and OS 77% and 46%. CONCLUSIONS: Surface mold brachytherapy is a viable modality as either primary or boost treatment for superficial oral cancers. In our patients, this treatment method has a low toxicity profile and resulted in reasonable LC.

Depressive symptoms predict head and neck cancer survival: Examining plausible behavioral and biological pathways.

BACKGROUND: Head and neck cancers are associated with high rates of depression, which may increase the risk for poorer immediate and long-term outcomes. Here it was hypothesized that greater depressive symptoms would predict earlier mortality, and behavioral (treatment interruption) and biological (treatment response) mediators were examined. METHODS: Patients (n = 134) reported depressive symptomatology at treatment planning. Clinical data were reviewed at the 2-year follow-up. RESULTS: Greater depressive symptoms were associated with significantly shorter survival (hazard ratio, 0.868; 95% confidence interval [CI], 0.819-0.921; P < .001), higher rates of chemoradiation interruption (odds ratio, 0.865; 95% CI, 0.774-0.966; P = .010), and poorer treatment response (odds ratio, 0.879; 95% CI, 0.803-0.963; P = .005). The poorer treatment response partially explained the depression-survival relation. Other known prognostic indicators did not challenge these results. CONCLUSIONS: Depressive symptoms at the time of treatment planning predict overall 2-year mortality. Effects are partly influenced by the treatment response. Depression screening and intervention may be beneficial. Future studies should examine parallel biological pathways linking depression to cancer survival, including endocrine disruption and inflammation.

Depressive symptoms and actigraphy-measured circadian disruption predict head and neck cancer survival.

OBJECTIVE: Depressive symptoms have demonstrated prognostic significance among head and neck cancer patients. Depression is associated with circadian disruption, which is prognostic in multiple other cancer types. We hypothesized that depressive symptoms would be associated with circadian disruption in head and neck cancer, that each would be related to poorer 2-year overall survival, and that relationships would be mediated by tumor response to treatment. METHODS: Patients (N = 55) reported on cognitive/affective and somatic depressive symptoms (PHQ-9) and wore an actigraph for 6 days to continuously record rest and activity cycles prior to chemoradiation. Records review documented treatment response and 2-year survival. Spearman correlations tested depressive symptoms and circadian disruption relationships. Cox proportional hazard models tested the predictive capability of depressive symptoms and circadian disruption, separately, on survival. RESULTS: Depressive symptoms were significantly associated with circadian disruption, and both were significantly associated with shorter survival (somatic: hazard ratio [HR] = 1.325, 95% confidence interval [CI] = 1.089-1.611, P = .005; rest/activity rhythm: HR = 0.073, 95% CI = 0.009-0.563, P = .012; nighttime restfulness: HR = 0.910, 95% CI = 0.848-0.977, P = .009). Tumor response to treatment appeared to partly mediate the nighttime restfulness-survival relationship. CONCLUSIONS: This study replicates and extends prior work with new evidence linking a subjective measure of depression and an objective measure of circadian disruption-2 known prognostic indicators-to shortened overall survival among head and neck cancer patients. Continued examination should elucidate mechanisms by which depressive symptomatology and circadian disruption translate to head and neck cancer progression and mortality.

Depressive Symptoms, Systemic Inflammation, and Survival Among Patients With Head and Neck Cancer.

Importance: Patients with head and neck cancer experience high rates of depression. Depression and systemic inflammation have been found to be associated in numerous cancer types, often independently from disease status. Depression-related inflammation may elevate the risks for poor tumor response to treatment and early mortality, and comprises a mechanism by which depression is associated with survival in head and neck cancer. Objective: To assess mediation pathways incorporating pretreatment depressive symptoms, pretreatment inflammation, and tumor response posttreatment on overall survival among patients with head and neck cancer. Design, Setting, and Participants: This was a prospective observational cohort study of patients with head and neck cancer treated in a single multidisciplinary head and neck cancer clinic from May 10, 2013, to December 30, 2019, and followed up for 2 years. Data analysis was performed from June 29, 2022, to June 23, 2023. Exposures: Patient-reported depressive symptoms using the Patient Health Questionnaire-9 item (PHQ-9) at treatment planning; pretreatment hematology workup for systemic inflammation index (SII) score; and clinical data review for tumor response (complete vs incomplete) and overall survival. Main Outcomes: Two-year overall survival. Results: The total study cohort included 394 patients (mean [SD] age, 62.5 [11.5] years; 277 [70.3%] males) with head and neck cancer. Among 285 patients (72.3%) who scored below the clinical cutoff for depression on the PHQ-9, depressive symptoms were significantly associated with inflammation (partial r, 0.168; 95% CI, 0.007-0.038). In addition, both depression and inflammation were associated with early mortality (PHQ-9: hazard ratio [HR], 1.04; 95% CI, 1.02-1.07; SII: HR, 1.36; 95% CI, 1.08-1.71). The depression-survival association was fully mediated by inflammation (HR, 1.28; 95% CI, 1.00-1.64). Depressive symptoms were also associated with poorer tumor response (odds ratio, 1.05; 95% CI, 1.01-1.08), and the depression-survival association was partially mediated by tumor response (HR, 9.44; 95% CI, 6.23-14.32). Systemic inflammation was not associated with tumor response. Conclusions: In this cohort study, systemic inflammation emerged as a novel candidate mechanism of the association of depression with mortality. Tumor response partially mediated effects of depression on mortality, replicating prior work. Thus, depression stands out as a highly feasible target for renewed clinical attention. Even mild symptoms of depression during the treatment-planning phase may be associated with higher systemic inflammation in addition to poorer tumor response to treatment and survival outcomes; therefore, depression should be clinically addressed.

Radiotherapy Plus Cisplatin With or Without Lapatinib for Non-Human Papillomavirus Head and Neck Carcinoma: A Phase 2 Randomized Clinical Trial.

Importance: Patients with locally advanced non-human papillomavirus (HPV) head and neck cancer (HNC) carry an unfavorable prognosis. Chemoradiotherapy (CRT) with cisplatin or anti-epidermal growth factor receptor (EGFR) antibody improves overall survival (OS) of patients with stage III to IV HNC, and preclinical data suggest that a small-molecule tyrosine kinase inhibitor dual EGFR and ERBB2 (formerly HER2 or HER2/neu) inhibitor may be more effective than anti-EGFR antibody therapy in HNC. Objective: To examine whether adding lapatinib, a dual EGFR and HER2 inhibitor, to radiation plus cisplatin for frontline therapy of stage III to IV non-HPV HNC improves progression-free survival (PFS). Design, Setting, and Participants: This multicenter, phase 2, double-blind, placebo-controlled randomized clinical trial enrolled 142 patients with stage III to IV carcinoma of the oropharynx (p16 negative), larynx, and hypopharynx with a Zubrod performance status of 0 to 1 who met predefined blood chemistry criteria from October 18, 2012, to April 18, 2017 (median follow-up, 4.1 years). Data analysis was performed from December 1, 2020, to December 4, 2020. Intervention: Patients were randomized (1:1) to 70 Gy (6 weeks) plus 2 cycles of cisplatin (every 3 weeks) plus either 1500 mg per day of lapatinib (CRT plus lapatinib) or placebo (CRT plus placebo). Main Outcomes and Measures: The primary end point was PFS, with 69 events required. Progression-free survival rates between arms for all randomized patients were compared by 1-sided log-rank test. Secondary end points included OS. Results: Of the 142 patients enrolled, 127 (median [IQR] age, 58 [53-63] years; 98 [77.2%] male) were randomized; 63 to CRT plus lapatinib and 64 to CRT plus placebo. Final analysis did not suggest improvement in PFS (hazard ratio, 0.91; 95% CI, 0.56-1.46; P = .34) or OS (hazard ratio, 1.06; 95% CI, 0.61-1.86; P = .58) with the addition of lapatinib. There were no significant differences in grade 3 to 4 acute adverse event rates (83.3% [95% CI, 73.9%-92.8%] with CRT plus lapatinib vs 79.7% [95% CI, 69.4%-89.9%] with CRT plus placebo; P = .64) or late adverse event rates (44.4% [95% CI, 30.2%-57.8%] with CRT plus lapatinib vs 40.8% [95% CI, 27.1%-54.6%] with CRT plus placebo; P = .84). Conclusion and Relevance: In this randomized clinical trial, dual EGFR-ERBB2 inhibition with lapatinib did not appear to enhance the benefit of CRT. Although the results of this trial indicate that accrual to a non-HPV HNC-specific trial is feasible, new strategies must be investigated to improve the outcome for this population with a poor prognosis.

Surgical salvage of cancer of the oropharynx after chemoradiation.

Advanced oropharyngeal squamous cell carcinoma is treated primarily with chemoradiation, with the goal of excellent disease control and preservation of swallowing and articulation functions of the oropharynx. Disease control rates generally are excellent; however, a significant number of patients do not achieve locoregional control of disease. The importance of human papillomavirus expression in predicting successful tumor response, locoregional control, and survival following chemoradiation is increasingly confirmed. Emerging is a clinical profile, viral expression, and genetic expression pattern that can predict success of chemoradiation and indicate which patients are at higher risk for locoregional failure necessitating surgical salvage. Successful surgical salvage depends on restaging at the time of recurrence and the time interval from chemoradiation to recurrence. Although surgical morbidity and mortality remain a challenge in patients undergoing salvage surgery of the oropharynx after radiation failure with or without chemotherapy, they may be mitigated by liberal application of regional and microvascular free flap reconstruction techniques.

Development of a telehealth intervention for head and neck cancer patients.

Treatment for head and neck cancer precipitates a myriad of distressing symptoms. Patients may be isolated both physically and socially and may lack the self-efficacy to report problems and participate as partners in their care. The goal of this project was to design a telehealth intervention to address such isolation, develop patient self-efficacy, and improve symptom management during the treatment experience. Participatory action research and a review of the literature were used to develop electronically administered symptom management algorithms addressing all major symptoms experienced by patients undergoing treatment for head and neck cancers. Daily questions and related messages were then programmed into an easy-to-use telehealth messaging device, the Health Buddy(R). Clinician and patient acceptance, feasibility, and technology issues were measured. Using participatory action research is an effective means for developing electronic algorithms acceptable to both clinicians and patients. The use of a simple tele-messaging device as an adjunct to symptom management is feasible, affordable, and acceptable to patients. This telehealth intervention provides support and education to patients undergoing treatment for head and neck cancers.

Prognostic factors and selection criteria in the retreatment of head and neck cancers.

OBJECTIVES: To determine predictors of treatment selection, outcome, and survival, we examined a cohort of previously irradiated head and neck squamous cell carcinoma (HNSCC) patients. MATERIALS AND METHODS: We retrospectively analyzed 100 patients at our institution who were treated for recurrent or second primary (RSP) HNSCC, focusing on subgroups receiving reirradiation (ReRT) alone and those undergoing surgical salvage (SS) with or without post-operative reirradiation therapy (POReRT). Logistic regression modeling was performed to identify factors predictive of retreatment modality. Cox regression modeling was used to determine prognostic factors for progression free survival (PFS) and overall survival (OS). RESULTS: ReRT alone was less likely in current smokers and neck recurrences, with reirradiation more likely in primary site recurrences. POReRT was significantly more likely in patients with positive surgical margins (PSM), neck dissection, or organ dysfunction. POReRT omission negatively impacted PFS when PSM (HR: 8.894, 95% CI: 1.742-45.403) and perineural invasion (PNI) (HR: 3.391, 95% CI: 1.140-10.089) were present. Tracheostomy was associated with worse OS, but ReRT alone and POReRT improved OS. PSM correlated with worse OS, regardless of whether POReRT was given (HR: 14.260, 95% CI: 2.064-98.547). CONCLUSION: This analysis confirms known factors for predicting outcome and shows nonsmoking status and primary site recurrence as predictors for ReRT alone. POReRT for PSM and PNI improves PFS. Tracheostomy patients are more likely to have ReRT due to acute toxicity not limiting treatment and POReRT improves OS compared to surgery alone. The presence of PSM negatively impacts survival which cannot be overcome by POReRT.

Medical decision analysis: indications for tympanostomy tubes in RAOM by age at first episode.

OBJECTIVE: To compare utility estimates between tympanostomy tubes (TT) and short-courses of antibiotics in children with recurrent acute otitis media (RAOM) stratified by age at first episode. STUDY DESIGN AND SETTING: Formal decision analysis. RESULTS: The model recommended TT sooner in children with a history of a first episode of AOM occurring early in life. In children over 12 months old at onset, TT were recommended with seven episodes in 24 months, five episodes in 12 months, and three episodes in six months. In children under six months old at onset, TT were recommended with three episodes in 24 months and two episodes in a six-month or 12-month time span. CONCLUSIONS: Earlier TT may be indicated in children who developed a first episode of AOM at a very young age because of the higher risk of AOM recurrence. SIGNIFICANCE: This study is the first formal decision analysis to compare tympanostomy tubes and short-courses of antibiotics stratified by age at onset of the first AOM episode.

Intra-operative parathyroid identification using methylene blue in parathyroid surgery.

The objective of this study was to determine the value of intra-operative methylene blue (MB) during parathyroid surgery. We did a retrospective study of 473 patients after initial exploration for previously untreated symptomatic primary hyperparathyroidism. Procedural and post procedural data were collected on four groups of patients: minimally invasive parathyroidectomy with MB (n = 147), and without MB (n = 205), bilateral parathyroid exploration with intra-operative parathormone assay with MB (n = 56), and without MB (n = 65). Length of surgery was shorter for patients explored with MB (P = 0.026). For the minimally invasive parathyroidectomy group, the difference between the MB and non-MB groups was seven minutes. Twelve minutes was the difference between the MB and non-MB intra-operative parathormone assay groups. Length of stay, local complications, and correction of hypercalcemia after parathyroidectomy were not significantly affected by the use of MB. Systemic complications were lower in the MB groups. Aside from a statistically significant, but quantitatively minimal decrease in the length of surgery, no consistent benefit was identified with the use of MB for intra-operative parathyroid identification.

Fungal contribution in chondroradionecrosis of the larynx.

OBJECTIVE: To assess the prevalence of invasive fungal elements in the specimens of patients who underwent salvage total laryngectomy for chondroradionecrosis (CRN) in the absence of recurrent or persistent malignancy. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary academic medical center. METHODS: One hundred fifty-nine patients were identified who underwent salvage total laryngectomy. Pathology reports were reviewed, and all laryngectomy specimens that did not contain residual malignancy were reevaluated for evidence of invasive fungal elements. RESULTS: Twelve of 159 (7.5%) patients who underwent total laryngectomy after primary radiotherapy or chemoradiotherapy had no evidence of residual malignancy. Each of these specimens contained histopathologic evidence of CRN; invasive fungal elements were identified in 25%. There was no statistical difference in demographic or treatment-related variables between patients who underwent salvage total laryngectomy with evidence of persistent or recurrent malignancy in the laryngectomy specimen versus patients without evidence of tumor on final histopathologic analysis. Patients with evidence of ulceration or necrosis in the laryngectomy specimen had reduced overall survival, irrespective of the presence of persistent malignancy (hazard ratio = 2.923, 95% confidence interval = 1.023-8.352, P = .045). CONCLUSION: Among salvage total laryngectomy patients, no difference was identified between patients who underwent total laryngectomy for recurrent or persistent malignancy after primary radiotherapy and those who received total laryngectomy without evidence of malignancy in their specimens. Invasive fungal elements were detected in several laryngectomy specimens that did not contain residual malignancy. Empiric antifungal therapy may therefore benefit patients diagnosed with CRN who are at risk for progression to nonfunctional larynx. Patients with evidence of ulceration or necrosis in the salvage laryngectomy specimen had worse overall survival. LEVEL OF EVIDENCE: 4. Laryngoscope, 127:E159-E165, 2017.

High-dose versus weekly cisplatin definitive chemoradiotherapy for HPV-related oropharyngeal squamous cell carcinoma of the head and neck.

OBJECTIVES: To compare the outcomes and toxicity of high-dose cisplatin (HDC) versus weekly cisplatin (WC) definitive chemoradiotherapy (CRT) for patients with human papillomavirus (HPV) related oropharyngeal squamous cell carcinoma (SCCOPx). METHODS: All patients with p16 positive SCCOPx treated with definitive CRT with cisplatin between 2010 and 2014 at a single institution were retrospectively reviewed. CTCAE v 4.03 toxicity criteria were used. The Kaplan-Meier method was used to estimate event-free survival (EFS) and the overall survival (OS). RESULTS: Of the 55 patients included, 22 were patients treated with HDC at dose of 100mg/m2 on days 1 and 22; and the remaining 33 patients were treated with WC at 40mg/m2. Both cohorts received a median total dose of cisplatin of 200mg/m2. At median follow-up of 31months, there was one local failure and no distant failures in the HDC cohort. In the WC group, there were 6 total failures (2 local, 4 distant). Estimated 2-year EFS was better in HDC cohort as compared to WC (96% vs. 75%; p=0.04). There was no significant difference in 2-year OS (95% vs. 94%; p=0.40). Weight loss, gastric tube dependence at six months, acute renal injury and grade 3 or 4 hematological toxicity were all similar between both groups. CONCLUSIONS: HPV-related SCCOPx treated with definitive CRT with either HDC or WC had similar toxicity profile. HDC had better EFS when compared with WC and this seems to be driven by increased distant failure rates, although the OS was similar.

Microvessel density in head and neck squamous cell carcinoma primary tumors and its correlation with clinical staging parameters.

OBJECTIVE: Our objective was to assess angiogenesis in head and neck squamous cell primary tumors and measure its correlation with tumor site and clinical and pathologic staging parameters. STUDY DESIGN: Patients from the tumor registries of the University of Louisville and affiliated hospitals who had biopsy-proven head and neck squamous cell carcinoma were retrospectively assessed over a 5-year period (1995-2000). METHODS: Patient records were reviewed for tumor site, TNM staging, surgical treatment, and tumor pathologic staging data. Cell blocks were obtained for each of the study patients, and CD31 staining was used to measure microvessel density (MVD) in areas of primary tumor hot spots. RESULTS: Twenty-eight consecutive patients met inclusion criteria and had adequate cell blocks for evaluation. MVD for T3 staged (41.2 MVD, mean) and T4 staged (36.4 MVD, mean) tumors were higher than earlier staged T1 staged (31.3 MVD, mean) and T2 staged (24.9 MVD, mean) tumors. Laryngeal T3 and T4 tumors had MVDs as high as 43.4 MVD (mean) and 40.4 MVD (mean), respectively, compared with a 23.9 MVD for T2 tumors. This difference was statistically significant (P < .01). Our report indicates a trend toward increasing MVD with N-stage. CONCLUSION: Our series demonstrates that there is a strong correlation between MVD in primary tumor hot spots and tumor T-stage, which implies that tumor angiogenesis may be a factor in tumor progression.

Advantages of a targeted approach in minimally invasive radioguided parathyroidectomy surgery for primary hyperparathyroidism.

OBJECTIVE: In a large series of patients, we associated the need for preoperative parathyroid hormone (PTH) and calcium levels as a vital component in our approach to the radioguided minimally invasive parathyroidectomy (MIRP) procedure. Our objective was to determine whether these preoperative levels indeed complemented the procedure. Our study also included a postoperative assessment of excised gland volume and length of operation. STUDY DESIGN: This was a prospective cohort study. METHODS: : One hundred seventy-three patients with primary hyperparathyroidism enrolled in our radioguided MIRP protocol. Patients were divided into groups based on the results of sestamibi scans. Comparisons were made between these results and the assessed preoperative PTH and calcium levels and the postoperative excised gland volume and length of operation. RESULTS: PTH and calcium levels did not statistically relate with the likelihood of having a "positive," "equivocal," or "negative" sestamibi scan, but the volume of excised gland was significantly different among the three groups (P < .01). There was no significant difference between positive and equivocal scans (P = .40). Operative time was significantly different between positive and equivocal scans (P < .01), positive and negative scans (P < .01), and equivocal and negative scans (P < .01). CONCLUSIONS: Routine preoperative PTH and calcium levels are necessary for the biologic diagnosis of hyperparathyroidism, but they do not appear to relate to the outcome of a sestamibi scan and therefore do not complement the radioguided MIRP procedure. Because the size of the affected gland, however, did correlate with a positive sestamibi scan, we conclude that as the volume of the gland increases, so does the likelihood of a successfully chosen minimally invasive surgical approach.

Risk acceptance in laryngeal transplantation.

PURPOSE: Advancements in the fields of head and neck surgery and immunology have paved the way for new quality of life-improving procedures such as larynx transplantation. To quantitatively assess the risks versus benefits in larynx transplantation, we used a questionnaire-based survey (Louisville Instrument For Transplantation [LIFT]) to measure the degree of risk individuals are willing to accept to receive different types of transplantation procedures. METHODS: The LIFT contains 237 standardized questions incorporating standard gamble and time tradeoff outcome measures as well as questions assessing body image perception, depression, self-esteem, optimism, socially desirable responding, and demographics. Respondents were questioned on the extent to which they would trade off specific numbers of life-years, or sustain other costs, in exchange for receiving seven different types of transplant procedures. For this study, we questioned 243 individuals in three study populations with differing life experiences: healthy individuals, organ transplant recipients, and laryngectomees. RESULTS: All populations questioned perceived risks differently based on their varied life experiences and would accept differing degrees of risk for the different transplant procedures. Organ transplant recipients were the most risk-tolerant group, whereas laryngectomees were the least risk-tolerant. CONCLUSIONS: By questioning individuals with life experiences directly relevant to the risks and benefits associated with larynx transplantation, this study provides an empiric basis for assessing risk versus benefit in this new quality of life-improving procedure.

Toxic metabolic encephalopathy after parathyroidectomy with methylene blue localization.

OBJECTIVE: To determine the correlation between methylene blue use and toxic metabolic encephalopathy in patients undergoing surgery for primary hyperparathyroidism. STUDY DESIGN AND SETTING: A retrospective study of 193 patients was performed to collect demographic, perioperative, and postoperative data. Patients were divided into two groups: Group A (postoperative neurological sequelae) and Group B (no neurological sequelae). All data points were compared between the groups. RESULTS: Twelve of 193 patients were placed in Group A; 181 patients were placed in Group B. Ten patients in Group A were female, and 10 patients were older than 60 years. Of the patients in Group A, 100% were taking a serotonin reuptake inhibitor (SRI). In Group B, 8.8% of patients were taking an SRI. CONCLUSION: All the patients who experienced transient neurological events were taking an SRI. A correlation can be made between methylene blue infusion and SRI usage. SIGNIFICANCE: Patients taking SRIs may represent a high-risk group for postoperative neurological events when methylene blue is utilized.

Laryngeal examination in thyroid and parathyroid surgery: An American Head and Neck Society consensus statement: AHNS Consensus Statement.

This American Head and Neck Society (AHNS) consensus statement discusses the techniques of laryngeal examination for patients undergoing thyroidectomy and parathyroidectomy. It is intended to help guide all clinicians who diagnose or manage adult patients with thyroid disease for whom surgery is indicated, contemplated, or has been performed. This consensus statement concludes that flexible transnasal laryngoscopy is the optimal laryngeal examination technique, with other techniques including laryngeal ultrasound and stroboscopy being useful in selected scenarios. © 2016 Wiley Periodicals, Inc.

Prognostic significance of HPV status in postoperative squamous-cell carcinoma of the head and neck.

BACKGROUND: There are limited data on the prognostic significance of human papillomavirus (HPV) status in relation to traditional risk factors for head and neck squamous-cell carcinoma (HNSCC) in the postoperative setting. OBJECTIVE: To clarify the impact of HPV status on the risk for HNSCC in the postoperative setting. METHODS: We retrospectively evaluated an institutional cohort of 128 patients with HNSCC patients who had been treated with definitive surgery with or without adjuvant radiotherapy or chemoradiotherapy. Patient, disease, and treatment factors were analyzed as potential prognostic indicators. RESULTS: Lymph node extracapsular extension (ECE), perineural invasion (PNI), and lymphovascular space invasion (LVSI) positivity predicted poorer locoregional control (LRC), disease-free survival (DFS), and overall survival (OS). Positive margins related to poorer DFS and OS. HPV status alone did not predict LRC, DFS, or OS. Compared with patients who were HPV-positive and ECE-negative, both HPV-positive and HPV-negative patients with ECE experienced significantly poorer OS (78.6%, 60%, and 43.7%, respectively; 𝑃 = .010 and 𝑃 = .018, respectively). LIMITATIONS: Retrospective, single-institution study; small patient cohort; short follow-up time. CONCLUSION: The influence of HPV in postoperative HNSCC seems limited compared with traditional risk factors such as ECE, LVSI, and PNI. De-escalation of postoperative treatment based on HPV status alone should be approached with caution.

Operative failure rate and documentation of family history in young patients undergoing focused parathyroidectomy for primary hyperparathyroidism.

Primary hyperparathyroidism in multiple endocrine neoplasia type I usually affects all parathyroid glands, making focused parathyroidectomy (FP) inappropriate. The risk of previously undiagnosed multiple endocrine neoplasia type I in a younger patient with primary hyperparathyroidism is higher than in an older patient. We hypothesized that FP may lead to a higher failure rate in younger versus older patients. A retrospective review was performed of a single-institution database of patients who underwent parathyroidectomy for primary hyperparathyroidism. Routine statistical analysis was performed, including Fisher's exact test. A total of 635 patients were included. Operative failure occurred in 7/55 (13%) younger patients and 21/580 (4%) older patients (P = 0.007). In conclusion, operative failure occurred in a statistically significantly higher percentage of younger versus older patients undergoing FP. This is partly explained by undiagnosed multiple endocrine neoplasia syndrome type I in the younger patient group. Endocrine surgeons must make every effort to preoperatively identify multiple endocrine neoplasia syndrome type I in the younger patient population.
