There are no quantitative selection criteria for identifying high-grade glioma (HGG) patients who are suited for volumetric-modulated arc therapy (VMAT). This study aimed to develop selection criteria that can be used for the selection of the optimal treatment modality in HGG. We analyzed 20 patients with HGG treated by 3D conformal radiotherapy (3DCRT).

Background And Purpose: To compare chemoradiotherapy (CRT) with low-dose continuous 5-fluorouracil (5FU) to CRT with 5FU+cisplatin (CDDP) for esophageal squamous cell carcinoma (ESCC) in a retrospective cohort study.

Methods And Materials: We reviewed the cases of Stage I-IV ESCC patients who underwent definitive CRT in 2000-2014. Concomitant chemotherapy was one of the three regimens: (1) high-dose intermittent 5FU and CDDP (standard-dose FP: SDFP), (2) low-dose continuous 5FU and CDDP (LDFP), or (3) low-dose continuous 5FU (LD5FU).

Purpose: To investigate the effects of a respiratory gating and multifield technique on the dose-volume histogram (DVH) in radiotherapy for esophageal cancer.

Methods And Materials: Twenty patients who underwent four-dimensional computed tomography for esophageal cancer were included. We retrospectively created the four treatment plans for each patient, with or without the respiratory gating and multifield technique: No gating-2-field, No gating-4-field, Gating-2-field, and Gating-4-field plans.

In this study, the clinical effects were compared between a thromboxane synthetase inhibitor (sodium ozagrel) and a thrombolytic agent (urokinase) in patients with acute cerebral infarction. The subjects consisted of 598 patients admitted on the day of the onset of the cerebral infarction in the territory of the internal carotid artery who showed a low density area on CT images within 5 days. Of these patients, 300 were treated with sodium ozagrel and classified as Group Oz, while the remaining 298 were treated with urokinase and classified as Group Ur.

Early diagnosis of motor function status and changes in motor impairment level of the upper limbs and fingers in patients with acute cerebral infarction is important in establishing a treatment plan. This study investigated a method of predicting motor function outcome and changes in motor impairment based on the characteristics of symptoms on admission and severity according to the CT classification. The subjects were 309 patients with carotid-system cerebral infarction admitted on the day of onset of symptoms and who exhibited a low density area in the territory of the middle cerebral artery on CT images within 5 day of the onset of symptoms.
