Clinical, molecular- and cytogenetic analysis of a case of severe radio-sensitivity.

In radiotherapy the normal tissue reaction is often a limiting factor for radiation treatment. Still there is no screening method, which predicts normal tissue reaction on radiotherapy, especially in comparison to tumor tissue, and therefore allows tailoring of the radiation dose to each patient. Here, we present a case of severe radiation-related side effects.

Treatment of vascular soft tissue sarcomas with razoxane, vindesine, and radiation.

Purpose: In previous studies, razoxane and vindesine together with radiotherapy was proved to be effective in soft tissue sarcomas (STS). Because razoxane leads to a redifferentiation of pathological tumor blood vessels, it was of particular interest to study the influence of this drug combination in vascular soft tissue sarcomas.

Methods And Materials: This open multicenter Phase II study was performed by the Austrian Society of Radiooncology.

Lumpectomy plus tamoxifen or anastrozole with or without whole breast irradiation in women with favorable early breast cancer.

Purpose: In women with favorable early breast cancer treated by lumpectomy plus tamoxifen or anastrazole, it remains unclear whether whole breast radiotherapy is beneficial.

Methods And Material: Between January 1996 and June 2004, the Austrian Breast and Colorectal Cancer Study Group (ABCSG) randomly assigned 869 women to receive breast radiotherapy +/- boost (n = 414) or not (n = 417) after breast-conserving surgery (ABCSG Study 8A). Favorable early breast cancer was specified as tumor size <3 cm, Grading 1 or 2, negative lymph nodes, positive estrogen and/or progesterone receptor status, and manageable by breast-conserving surgery.

The med AUSTRON/OGRO patterns of care study on radiotherapy indications in Austria.

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.

Epidemiological aspects of hadron therapy: a prospective nationwide study of the Austrian project MedAustron and the Austrian Society of Radiooncology (OEGRO).

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.
