Radiotherapy of Breast Cancer-Professional Guideline 1st Central-Eastern European Professional Consensus Statement on Breast Cancer.

The international radiotherapy (RT) expert panel has revised and updated the RT guidelines that were accepted in 2020 at the 4th Hungarian Breast Cancer Consensus Conference, based on new scientific evidence. Radiotherapy after breast-conserving surgery (BCS) is indicated in ductal carcinoma (stage 0), as RT decreases the risk of local recurrence (LR) by 50-60%. In early stage (stage I-II) invasive breast cancer RT remains a standard treatment following BCS.

[4th Hungarian Breast Cancer Consensus Conference - Radiotherapy guidelines].

The radiotherapy (RT) expert panel revised and updated the RT guidelines accepted in 2016 at the 3rd Hungarian Breast Cancer Consensus Conference based on new scientific evidence. Radiotherapy after breast-conserving surgery (BCS) is indicated in ductal carcinoma in situ (St. 0), as RT decreases the risk of local recurrence (LR) by 50-60%.

[3rd Hungarian Breast Cancer Consensus Conference - Radiotherapy Guidelines].

The radiotherapy expert panel revised and updated the radiotherapy (RT) guidelines accepted in 2009 at the 2nd Hungarian Breast Cancer Consensus Conference based on new scientific evidence. Radiotherapy of the conserved breast is indicated in ductal carcinoma in situ (St. 0), as RT decreases the risk of local recurrence by 60%.

[Combined surgery and radiotherapy in the treatment of ductal carcinoma in situ of the breast: preliminary results of the Hungarian multicenter prospective randomised study].

The aim of this work is to report the preliminary results of the Hungarian multicentric randomised DCIS study. Between 2000 and 2007, 278 patients with ductal carcinoma in situ (DCIS) treated by breast-conserving surgery were randomised according to predetermined risk groups. Low/intermediate-risk patients (n=29) were randomised to 50 Gy whole-breast irradiation (WBI) or observation.

The role of radiotherapy in the conservative treatment of ductal carcinoma in situ of the breast.

Breast-conserving surgery (BCS) followed by radiotherapy (RT) has become the standard of care for the treatment of early-stage (St. I-II) invasive breast carcinoma. However, controversy exists regarding the value of RT in the conservative treatment of ductal carcinoma in situ (DCIS).

[The effect of chemo-radiotherapy on the remission and survival in patients with limited stage small cell lung cancer].

Introduction: The combined modality treatment used in case of limited stage small cell lung cancer assures the longest disease-free and average survival meanwhile maintaining an acceptable quality of life.

Object: The authors examined whether the combined modality treatment in case of limited-stage small cell lung cancer affects the remission positively or not: they presumed that the therapeutic response, early partial or complete clinical and oncological remission develops earlier than in patients treated with chemotherapy. The authors' other presumption was that the early therapeutic response could be the guarantee of the longest possible disease-free and average survival.
