From organ at risk to target organ: Dosimetric comparison of myocardial stereotactic ablative body radiotherapy between helical tomotherapy and volumetric arc therapy for refractory ventricular tachycardia.

Ventricular tachycardia (VT) is an important type of arrhythmia with a risk of sudden death. Although implanted cardiac defibrillation and radiofrequency ablation are used together with medical treatments for VT, the treatment options are limited in cases that do not respond to them. Stereotactic ablative body radiotherapy (SABR) applied to VT substrates in resistant cases is an emerging treatment with positive results.

A multicenter retrospective analysis of patients with nasopharyngeal carcinoma treated in IMRT era from a nonendemic population: Turkish Society for Radiation Oncology Head and Neck Cancer Group Study (TROD 01-001).

Background: We aimed to evaluate patients with nasopharyngeal carcinoma (NPC) in a nonendemic population.

Methods: In a national, retrospective, multicenteric study, 563 patients treated with intensity modulated radiotherapy at 22 centers between 2015 and 2020 were analyzed.

Results: Median age was 48 (9-83), age distribution was bimodal, 74.

Helical tomotherapy experience in breast cancer adjuvant radiotherapy and acute toxicity results.

Background: This study aimed to evaluate acute toxicity and oncological outcomes of breast cancer patients who underwent adjuvant radiotherapy (RT) with tomotherapy.

Materials And Methods: The results of 114 patients who underwent adjuvant RT with Tomotherapy device between 17.08.

Prognostic impact of immune inflammation biomarkers in predicting survival and radiosensitivity in patients with non-small-cell lung cancer treated with chemoradiotherapy.

Introduction: The purpose of this retrospective study was to investigate the prognostic impact of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), derived NLR (dNLR) and systemic immune-inflammation index (SII) in predicting outcomes for patients with locally advanced non-small-cell lung cancer (NSCLC). The secondary endpoint was to evaluate the radiosensitivity in terms of response rate.

Methods: Newly diagnosed locally advanced NSCLC patients were enrolled.

Improved disease-free survival with adjuvant radiotherapy in early-stage endometrial cancer: 10-year outcome analysis.

Purpose: The purpose of this study was to evaluate long-term treatment outcomes and prognostic factors affecting survival of patients with early-stage endometrial carcinoma.

Material And Methods: Data of 311 patients with FIGO stage I-II endometrial cancer, curatively treated at two different tertiary centers between June 2001 and December 2016 were retrospectively reviewed. The patients had primary surgery, 74 (24%) received no further treatment, 4 (1%) obtained chemotherapy only, 234 (75%) received radiotherapy, and 24 (7%) received both.

Computed tomography-guided transthoracic biopsy: Factors influencing diagnostic and complication rates.

Objective This study was performed to assess the complication and diagnostic rates of computed tomography (CT)-guided transthoracic needle biopsy of pulmonary parenchymal and mediastinal lesions. Methods Patients who were suspected to have a malignancy based on chest imaging and CT and could not be otherwise diagnosed were evaluated. Results Sixty-five patients were included; 48 (73.
