Clinical association between plan complexity and the local-recurrence-free-survival of non-small-cell lung cancer patients receiving stereotactic body radiation therapy.

Purpose: To investigate the clinical impact of plan complexity on the local recurrence-free survival (LRFS) of non-small cell lung cancer (NSCLC) patients treated with stereotactic body radiation therapy (SBRT).

Methods: Data from 123 treatment plans for 113 NSCLC patients were analyzed. Plan-averaged beam modulation (PM), plan beam irregularity (PI), monitor unit/Gy (MU/Gy) and spherical disproportion (SD) were calculated.

High-Dose Versus Standard-Dose Intensity-Modulated Radiotherapy With Concurrent Paclitaxel Plus Carboplatin for Patients With Thoracic Esophageal Squamous Cell Carcinoma: A Randomized, Multicenter, Open-Label, Phase 3 Superiority Trial.

Purpose: The standard dose (SD) of definitive concurrent chemoradiotherapy (dCRT) remains 50.4 Gy in patients with esophageal cancer; a higher dose, when applied with conventional radiation therapy techniques, increases toxicities without improving survival. We investigated whether a high dose of 59.

Comparison of Contrast-Enhanced Ultrasonography to Color Doppler Ultrasound in Evaluation of Carotid Body Tumors.

Objective: The objectives of this study were to prospectively 1) explore the characteristics and enhanced patterns of carotid body tumors (CBTs) at color Doppler ultrasound (CDU) and contrast-enhanced ultrasonography (CEUS) qualitatively and quantitatively and 2) compare CDU and CEUS for their morphology and vascularity signature.

Methods: CDU and CEUS with Sonovue were used to evaluate 25 CBT lesions. The comparison between these ultrasonic modalities included the size, Shamblin type, vascularity, and feeding vessels of the lesion areas.

Hypofractionated Volumetric-Modulated Arc Radiotherapy for Patients With Non-Small-Cell Lung Cancer Not Suitable for Surgery or Conventional Chemoradiotherapy or SBRT.

Background: Hypofractionated radiotherapy (HypoRT) has been used to pursue an alternative treatment regimen for patients with non-small-cell lung cancer (NSCLC) who are not eligible for stereotactic ablative radiotherapy (SABR), surgery or concurrent chemoradiotherapy (CCRT) and has shown good local control and safety. We analyzed the feasibility of using volumetric-modulated arc radiotherapy (VMAT) with the simultaneous integrated boost (SIB) technique to achieve high local control with few treatment-related toxicities.

Patients And Methods: A total of 55 patients with stage I-IV NSCLC who were not candidates for SABR, surgery or CCRT were included in the present study.

Management of cervical aortic arch complicated by multiple aneurysms.

Objectives: Cervical aortic arch with aneurysm formation is considered an extremely rare condition. Here, we summarize our experience in treating 8 patients. We validated extra-anatomic ascending-to-infrarenal abdominal aorta bypass through the retroperitoneal cavity without circulatory arrest as an alternative treatment for patients with a tortuous arch that was unsuitable for endovascular repair.

Surgical treatment for rare isolated left innominate vein aneurysms.

Thoracic venous aneurysms are rare, with the fusiform superior vena cava being the most commonly reported. Isolated innominate vein aneurysms are extremely rare. Herein, we report the case of a saccular left innominate vein aneurysm with an intraluminal thrombus treated with surgical excision and simple reconstruction of the innominate vein.
