Objectives: To analyze characteristics, treatment outcomes, and prognostic factors of sarcomatoid squamous cell carcinoma of the head and neck. Study Design: Retrospective chart review. Setting: Tertiary care center. Subjects and Methods: Fifty-five patients were treated for sarcomatoid squamous cell carcinoma of the head and neck between 1996 and 2018. Data collection included clinical history, tumor characteristics, pathology, treatment modality, and outcomes. Mean follow up was 17.1 months. Cox univariate analysis was used to evaluate for associations with locoregional recurrence, distant metastasis, and overall survival. Results: Most patients were white males with a smoking history and median age 66 years (range 41-92) at diagnosis. Twenty-two percent had prior head and neck radiation. Tumor site was most frequently oral cavity (41.8%), followed by larynx (29.1%), and oropharynx (16.4%). Half presented with early T stage disease (15.5% T0, 12.7% T1, 30.9% T2) and the remainder with late stage disease (16.4% T3, 34.5% T4). Locoregional recurrence rate was 60.0%, metastatic recurrence was rate 21.8%, with median time to recurrence of 4 months and mean overall survival of 20 months. Presence of lymphovascular space invasion was statistically associated with locoregional recurrence (P =.018, HR 3.55 [95% CI 1.24, 10.14]) and poorer overall survival (P =.015, HR 2.92 [95% CI 1.23, 4.80]). Treatment with multimodality therapy was associated with decreased locoregional recurrence (P =.039, HR 0.39 [95% CI 0.16, 0.95]) but did not impact overall survival. Conclusion: Sarcomatoid squamous cell carcinoma remains a rare and aggressive disease variant with high recurrence rates and high mortality. High risk features such as lymphovascular space may indicate the need for more aggressive therapy. [ABSTRACT FROM AUTHOR]

The article presents the findings of a study regarding the effectiveness of adjuvant cryotherapy for the treatment of early glottic cancer and laryngeal papillomatosis. The study finds that the use of adjuvant cryotherapy for early glottic cancer treatment does not improve the rate of carcinoma recurrences and does not increase the duration of disease-free period for patients with laryngeal papillomatosis. Details on the methods and design of the study are given.

Background context Some, smaller studies have investigated the effect of preoperative depression on postoperative improvement in quality of life (QOL). However, they have not used the Patient Health Questionnaire 9 (PHQ-9) in self-reported depression. Purpose To assess the effect of preoperative depression as measured by the PHQ-9 on postoperative improvement in QOL. Study design A retrospective review at a single tertiary-care referral center. Patient sample Patients who underwent lumbar decompression or fusion between 2008 and 2012. Outcomes measures A self-reported EuroQol five-dimensions (EQ-5D) quality-adjusted life-years Index. Methods Quality of life data were collected using the institutional prospectively collected database of patient-reported health status measures. The EQ-5D questionnare, PDQ, and PHQ-9 were used. Linear and logistic regression analyses were performed to assess the impact of preoperative depression on QOL improvement. Results Elevated preoperative pain (PDQ, β=−0.0017, p=.0009) and worsened depression (PHQ-9, β=−0.0044, p=.0359) were significantly associated with diminished postoperative improvement in QOL, as measured by the EQ-5D. Furthermore, greater depression (PHQ-9, odds ratio [OR] 0.93, p<.0001) and pain (PDQ, OR 0.99, p=.02) were associated with significantly diminished postoperative improvement exceeding the minimum clinically important difference. Conclusions Increased preoperative pain and depression were shown to be associated with significantly reduced improvement in postoperative QOL, as measured by the EQ-5D. [ABSTRACT FROM AUTHOR]

Background context C5 nerve root palsy (C5P) is a relatively rare complication after anterior and posterior cervical decompression surgery that leads to a variety of debilitating symptoms. The precise etiology remains obscure, and a clear understanding of preoperative risk factors for C5P development does not exist. Purpose To determine whether postoperative C5P can be predicted from preoperative anteroposterior diameter (APD), foraminal diameter (FD), and/or cord-lamina angle (CLA). Study design Retrospective review. Patient sample Consecutive patients who underwent either anterior or posterior decompression surgery at C4-C5 for cervical spondylotic myelopathy. Outcome measures Development of C5P. Methods Blinded reviewers retrospectively assessed magnetic resonance images for each included patient's C4-C5 interspace, including the midline APD, the left and right FDs, and the left and right CLA. Multivariable logistic regression was used to model the probability of palsy on the basis of one or more predictors. A jackknife validation was performed to internally validate the model and assess its generalizability. Results A total of 98 patients fit the inclusion criteria; 12% had developed symptoms of C5 palsy postoperatively. Using the three variables in a predictor-model, we found that the odds ratio of having palsy for APD, FD, and CLA was 0.3, 0.02, and 1.4, respectively. For every 1-mm increase in APD and FD, the odds of developing palsy decrease 69% (p<.0001) and decrease 98% (p<.0003), respectively. In contrast, for every 1-degree increase in CLA, the odds of developing palsy increase by 43% (p<.0001). The receiver-operating characteristic curve for this three-variable model predicting development of palsy has an area under the curve (concordance index) of 0.97. After implementing a jackknife validation, the area under the curve was 95%. Conclusions This study is the first to use the combination of APD, FD, and CLA to predict development of postoperative C5 palsy after decompression surgery for patients with spondylotic myelopathy. This prediction formula may allow for better patient selection and to prepare patients that have an increased probability of developing this complication. [ABSTRACT FROM AUTHOR]

Study Design: A consecutive retrospective cohort study from 2008 to 2013 at a single tertiary-care institution was conducted.Objective: The aim of the study was to characterize recovery from pain and neurologic deficit after surgery for vertebral osteomyelitis (VO), and identify incidence of postoperative adverse events.Summary Of Background Data: A minority of patients with VO require surgery. Although prior studies have characterized outcomes after medical management, the morbidity after surgery is poorly defined.Methods: The primary outcome was change from baseline in a Modified McCormick Scale (MMS, 1-5 scale), whereas secondary outcomes included reoperation and change in self-reported pain Visual Analog Scale (VAS, 0-10 scale). MMS and VAS were collected throughout the postoperative course as surrogates for neurologic function and degree of pain. Intraoperative, short-term postoperative (<30 d), and long-term neurologic complications were recorded. New-onset neurologic deficits in the postoperative period were considered neurologic complications.Results: Fifty patients were included; a majority (52%) presented with a neurologic deficit. The median length of follow-up was 18 months. A statistically significant improvement in MMS was observed by 12 months postoperatively, whereas an improvement in VAS was observed by 3 months. The mean improvement in MMS at last follow-up was 0.35, whereas the mean improvement in VAS was 3.40. One quarter of patients required reoperation. At 24 months postoperatively, 10% died, 26% underwent reoperation, 42% experienced a neurologic complication, and 60% experienced at least one of these 3 adverse events.Conclusion: This is the first study to investigate neurologic complications, reoperation, and pain in a longitudinal manner after surgery for VO. We observed statistically significant improvements in MMS and VAS in the postoperative period. Despite these improvements, the 24-month incidence of overall adverse events was 60%. Patients and clinicians should be aware of the clinical improvement but high incidence of adverse events after surgical management of VO.Level Of Evidence: 4. [ABSTRACT FROM AUTHOR]

Head and neck squamous cell carcinomas (HNSCC) induced by human papillomavirus (HPV) have increased recently in the US. However, the distinct alterations of molecules involved in the death pathways and drug effects targeting inhibitor of apoptosis proteins (IAPs) have not been extensively characterized in HPV(+) HNSCC cells. In this study, we observed the distinct genomic and expression alterations of nine genes involved in cell death in 55% HNSCC tissues, which were associated with HPV status, tumor staging, and anatomic locations. Expression of four genes was statistically correlated with copy number variation. A panel of HPV(+) HNSCC lines showed abundant TRAILR2 and IAP1 protein expression, but were not sensitive to IAP inhibitor birinapant alone, while combinatory treatment with TNFα or especially TRAIL enhanced this drug sensitivity. The death agonistic TRAILR2 antibody alone showed no cell inhibitory effects, whereas its combination with birinapant and/or TRAIL protein demonstrated additive or synergistic effects. We observed predominantly late apoptosis mode of cell death after combinatorial treatments, and pan-caspase (ZVAD) and caspase-8 (ZIETD) inhibitors attenuated treatment-induced cell death. Our genomic and expression data-driven study provides a framework for identifying relevant combinatorial therapies targeting death pathways in HPV(+) HNSCC and other squamous cancer types.
