Background And Purpose: Comparing oncological outcomes and toxicity after primary treatment of localized prostate cancer using HDR- or LDR-mono-brachytherapy (BT), or conventionally (CF) or moderately hypofractionated (HF) external beam radiotherapy.
Materials And Methods: Retrospectively, patients with low- (LR) or favorable intermediate-risk (IR) prostate cancer treated between 03/2000 and 09/2022 in two centers were included. Treatment was performed using either CF with total doses between 74 and 78 Gy, HF with 2.
Purpose: We conducted a patterns-of-care survey on chemoradiation for locoregionally confined anal cancer in Austria to evaluate areas of disagreement and to identify possible targets for further standardization.
Methods: An anonymous questionnaire comprising 38 questions was sent to all Austrian radiation oncology departments. Results were analyzed descriptively and compared to two international guidelines.
Background: A comprehensive evaluation of the current national and regional radiotherapy capacity in Austria with an estimation of demands for 2020 and 2030 was performed by the Austrian Society for Radiation Oncology, Radiobiology and Medical Radiophysics (ÖGRO).
Materials And Methods: All Austrian centers provided data on the number of megavoltage (MV) units, treatment series, fractions, percentage of retreatments and complex treatment techniques as well as the daily operating hours for the year 2014. In addition, waiting times until the beginning of radiotherapy were prospectively recorded over the first quarter of 2015.
Background: This multicentric randomized phase II study investigated the feasibility and toxicity of temozolomide (TMZ) added to whole brain radiotherapy (WBRT) followed by adjuvant TMZ in patients with multiple brain metastases of non-small-cell lung cancer (NSCLC).
Methods: Patients with multiple brain metastases from NSCLC aged ≥ 18 years, classified according to recursive partitioning analysis class I or II and with adequate organ functions were eligible. Treatment consisted of WBRT + TMZ 75 mg/m² for 2 weeks followed at day 28 by TMZ 100 mg/m²/day 2 weeks on/2 weeks off for up to 6 months (radiochemotherapy, RCT) or WBRT alone (radiotherapy, RT).
Background And Purpose: To assess feasibility, safety and effectiveness of CT-based 3D conformal external beam radiotherapy (EBRT) plus concurrent cisplatin and MRI-based 3D conformal HDR-brachytherapy (HDR-BT) in the treatment of advanced cervical cancer.
Patients And Methods: A total of 48 patients with advanced cervical cancer, treated with CT-based EBRT plus simultaneous cisplatin chemotherapy (40mg/m(2) of body surface per week for 5 weeks) and MRI-based HDR-BT, were included for analysis.
Results: All patients completed radiotherapy as planned and 90% received at least four cycles chemotherapy.
Purpose: In Austria a national survey was conducted by Med AUSTRON/Osterreichische Gesellschaft for Radio--Onkologie, Radiobiologie und Medizinische Radiophysik (OGRO) in order to estimate the indications, patient numbers and radiotherapy treatment planning procedures and performances at all Austrian radiotherapy institutes. Results were correlated with incidence rates (Austrian cancer registry) to determine patterns of radiotherapy practice in Austria.
Material And Methods: At 12 radiotherapy departments of Austria data of all patients receiving irradiation within a 3 months (2002/2003) period were assessed.
Background: The planned MedAustron hadron therapy facility is designed to compare proton and carbon ion beam therapy under the same technical conditions. For the calculation of the number of potential patients for hadron therapy so far, only epidemiological estimations on cancer incidence are available without inclusion of the percentage of patients routinely referred to conventional radiotherapy.
Materials And Methods: Nationwide prospective survey to collect disease and treatment related data on patients receiving conventional radiotherapy at all 12 treatment facilities.
