Purpose: The objective of this study was to determine the negative predictive value (NPV) of positron emission tomography (PET)/computed tomography (CT) for the clinically N0 neck on the basis of neck dissection.
Methods: Participants with newly diagnosed, first-time, head and neck squamous cell carcinoma (HNSCC) and at least one clinically N0 neck side for which dissection was planned were included. A total of 287 participants were prospectively enrolled from 23 American College of Radiology Imaging Network-qualified institutions. PET/CT was compared with findings at neck dissection.
Results: PET/CT scans and pathology findings were available for 270 N0 neck sides from 212 participants. For visual assessment, the NPV specific to the clinical-N0 sides was 0.868 (95% CI, 0.803 to 0.925). For dichotomized maximum standardized uptake value, the NPVs specific to the nodal basins were 0.940 (95% CI, 0.928 to 0.952) and 0.937 (95% CI, 0.925 to 0.949) at prespecified cutoffs of 2.5 and 3.5, respectively. The optimal cutoff maximum standardized uptake value was determined to be 1.8, with an NPV of 0.942 (95% CI, 0.930 to 0.953). The PET/CT-informed surgical treatment plan was changed in 51 of 237 participants (22%) compared with the PET/CT-blinded surgical plan. In 34 participants (14%), this led to planned dissection of additional nodal levels. In 12 participants (5%), this led to fewer planned dissected nodal levels. Negative PET/CT scans in N0 necks was true negative in 87% and false negative in 13%.
Conclusion: [F]fluorodeoxyglucose-PET/CT has high NPV for the N0 neck in T2 to T4 HNSCC. The surgical treatment plans on the basis of PET/CT findings may be changed in approximately 22% of this group. These findings suggest that [F]fluorodeoxyglucose-PET/CT may assist the clinician in deciding on the best therapy for the clinically N0 neck in HNSCC. Well-designed clinical trials should be performed to test the outcome of omitting neck dissection by using PET/CT.

Purpose: The purpose of this study was to investigate the outcomes of minimally invasive PCF using an interfacet joint fusion cage.
Methods: The inclusion criteria consisted of patients who underwent a PCF using an interfacet device (Cavux, Providence Medical Technology Inc.) at a single institution and were at least 6 months postoperative.

Background: Endoscopic techniques allow for improved visualization and tumor debulking of pituitary adenomas. More thorough tumor resection, however, can be associated with higher rates of CSF leaks. We set out to determine if CSF leaks influenced patient perceived quality of life outcomes.

Background: PD-L1 expression in tumors and immune cells is a biomarker for the efficacy of anti-PD-1 antibody (APA) therapy across diverse cancers. Based on the results from the KEYNOTE-048 trial, pembrolizumab monotherapy is indicated for platinum-sensitive recurrent/metastatic head and neck squamous cell carcinoma (R/M-HNSCC) with a positive combined positive score (CPS). Conversely, nivolumab is utilized for platinum-pretreated R/M-HNSCC regardless of the positive tumor proportion score (TPS) following the results of the CheckMate-141; however, its subgroup analysis indicated that TPS-positive population tended to have a relatively high overall response rate and progression-free survival (PFS).

Material And Methods: 28 patients were included in this study. Group 1 was the semi-rigid group (four male, ten fe-male), group 2 was the fusion group (nine male, five female).

Graves' disease (GD) is an autoimmune disorder with a high incidence rate, particularly affecting women of reproductive age. Current treatment modalities for GD carry significant disadvantages, especially for pregnant or nursing women. As a novel extracorporeal therapeutic technique, high-intensity focused ultrasound (HIFU) shows great promise for treating GD; however, its low treatment efficacy impedes clinical application.
