Prevalence and factors associated with professional burnout in Polish oncologists-results of a nationwide survey.

Background: High rates of burnout are observed among health care professionals worldwide, which could have negative consequences on personal and organizational levels. We aimed to evaluate the burnout prevalence and factors associated with burnout among oncologists in Poland.

Materials And Methods: An online survey was conducted using the validated Maslach Burnout Inventory-Human Services Survey (MBI-HSS) and additional work/lifestyle questions.

Salvage re-irradiation in non-melanoma skin cancers: A multicenter analysis.

Background And Purpose: We conducted a multicentre real-world study to assess the outcomes of radical salvage re-irradiation for non-melanoma skin cancer (nMSC) recurrences following definitive or postoperative radiotherapy.

Materials And Methods: Data on patients treated between 2006 and 2022 with re-irradiation for nMSCs were retrospectively collected from five high-volume brachytherapy centers. The primary endpoint was local control (LC).

Real-life data of abiraterone acetate and enzalutamide treatment in post-chemotherapy metastatic castration-resistant prostate cancer in Poland.

Background: Abiraterone acetate (ABI) and Enzalutamide (ENZA) are second-generation hormone drugs that show breakthrough activity in post-chemotherapy, metastatic castration-resistant prostate cancer (mCRPC). The leading oncological and urological guidelines indicate both drugs with the same strong recommendation. There is a lack of randomized trials which compare the efficacy of ABI and ENZA.

Attitudes of Patients with Cancer towards Vaccinations-Results of Online Survey with Special Focus on the Vaccination against COVID-19.

Recently developed COVID-19 vaccines significantly reduce the risk of severe coronavirus disease, which is essential in the particularly vulnerable cancer patient population. There is a growing anti-vaccine concern that may affect the success of the fight against the SARS-CoV2 pandemic. To evaluate opinions and attitudes toward vaccination, we conducted an anonymous online survey among Polish patients diagnosed with cancer.

Analysis of dose distribution between contemporary and standard planning in high-dose-rate endobronchial brachytherapy based on three-dimensional imaging.

Purpose: The treatment planning (TP) in high-dose-rate (HDR) endobronchial brachytherapy (EB) can be based on various forms of imaging. In the case of lung cancer, one-dimensional or two-dimensional imaging is standard. The dose coverage of the target (planning target volume - PTV) and organs at risk (OAR) is unknown, because the doses are calculated on the basis of the dose points.

Long-term follow-up and comparison of techniques in radiofrequency ablation of ventricular arrhythmias originating from the aortic cusps (AVATAR Registry).

Introduction: Radiofrequency ablation (RFA) of outflow tract ventricular arrhythmia (VA) that originates from the aortic cusps can be challenging. Data on long‑ term efficacy and safety as well as optimal technique after aortic cusp ablation have not previously been reported.

Objectives: This aim of the study was to determine the short- and long‑ term outcomes after RFA of aortic cusp VA, and to evaluate aortic valve injuries according to echocardiographic screening.

Clinical target volume in postoperative radiotherapy for gastric cancer: identification of major difficulties and controversies.

Purpose: To identify the main difficulties in postoperative clinical target volume (CTV) delineation in gastric cancer (GC).

Methods: Before and after a training course, 20 radiation oncology residents were asked to delineate the CTV for the postoperative GC case on four computed tomography scans: dome of the diaphragm, anterior abdominal wall, duodenal stump and porta hepatis level, and to determine the lower CTV border. CTV volume was reconstructed from requested planar contours.

The evaluation of treatment plans in high-dose-rate endobronchial brachytherapy by utilizing 2D and 3D computed tomography imaging methods.

Purpose: To present comparison of treatment plans made by using 2D and 3D methods in the planning system, as well as to assess the quality of treatment plans using the 2D and 3D methods.

Material And Methods: The studies involved a group of 31 patients with advanced lung cancer treated in the Brachytherapy Department of the Subcarpathian Cancer Center in Brzozów from 2011 to 2013. In total, 31 patients and 76 treatment plans were analyzed.

Comparison of the GTV coverage by PTV and isodose of 90% in 2D and 3D planning during endobronchial brachytherapy in the palliative treatment of patients with advanced lung cancer. Pilot study.

Purpose: Endobronchial brachytherapy (EB) is one way of treatment of patients with advanced lung cancer. Technological progress and the introduction of computed tomography for use in 3D planning allows one to define the area being treated very precisely, which gives an opportunity to extend survival, even in groups of patients receiving palliative care.

Material And Methods: In 2011, in the Brachytherapy Department of the Subcarpathian Oncological Center, a group of 12 consecutive patients with advanced cancer of the bronchus underwent palliative EB.
