Longitudinal Swallowing and Salivary Changes With CLR 131 and Re‐Irradiation in Recurrent Head and Neck Cancer

Head &Neck, EarlyView.
ABSTRACT Background Patients with recurrent head and neck cancer (HNC) often present with severe, persistent dysphagia and xerostomia following prior chemoradiation. Although swallowing impairments and salivary dysfunction have been reported in this population, prior longitudinal studies have not examined changes in salivary composition or how these ...

Breast dosimetry using high-resolution voxel phantoms

, 2005
A computer model of X-ray mammography has been developed, which uses quasi-realistic high-resolution voxel phantoms to simulate the breast. The phantoms have 400 μm voxels and simulate the three-dimensional distributions of adipose and fibroglandular ...

Visualization of Scattered Tumor Regression Following Neoadjuvant Chemoimmunotherapy With a Novel Intraoperative PET/CT Scanner

Head &Neck, EarlyView.
ABSTRACT Background Neoadjuvant chemoimmunotherapy is being explored in locally advanced head and neck squamous cell carcinoma (HNSCC), yet the spatial patterns of pathologic response and clinical implications remain poorly characterized. Methods A 79‐year‐old female with recurrent left oral tongue SCC (PD‐L122C3 Combined Positive Score 90) who ...
