Predictors of prolonged treatment time intervals in oral cavity cancer.

Objectives: Delays in treatment time intervals have been associated with overall survival in oral cavity squamous cell carcinoma (OCSCC). The aim of this study was to identify bottlenecks leading to prolonged treatment intervals.

Material And Methods: A retrospective analysis was conducted using a cohort of OCSCC patients who underwent surgery and adjuvant radiation therapy.

Repeated Retching and Vomiting in the Pathophysiology of Isolated Spinal Aneurysms.

Background: Rupture of spinal aneurysms is a rare cause of subarachnoid hemorrhage. These aneurysms are often associated with a variety of vascular malformations that increase blood flow in the spinal circulation or with disorders that compromise the vessel wall. However, spinal aneurysms may be isolated, not associated with any known predisposing condition.

A Study of Pseudoprogression After Spine Stereotactic Body Radiation Therapy.

Purpose: To determine the incidence of pseudoprogression (PP) after spine stereotactic body radiation therapy based on a detailed and quantitative assessment of magnetic resonance imaging (MRI) morphologic tumor alterations, and to identify predictive factors distinguishing PP from local recurrence (LR).

Methods And Materials: A retrospective analysis of 35 patients with 49 spinal segments treated with spine stereotactic body radiation therapy, from 2009 to 2014, was conducted. The median number of follow-up MRI studies was 4 (range, 2-7).
