Adjuvant radiotherapy after modified radical mastectomy and breast-conserving surgery for early-stage invasive breast cancer substantially reduces the risk of locoregional failure and is evidence-based. Using traditional clinical and pathological factors, patients can be classified into subgroups by the risk of locoregional recurrence. In the high-risk groups the absolute benefit of irradiation is larger. ⋯ The radiation dose to the lung and heart can be significantly reduced by individualized CT-based treatment planning. The rate of Grade 3 atrophic dermatitis and fibrosis is 3-4%. The estimated incidence of ipsilateral breast angiosarcoma is less than 0.2%, but the mortality rate is high.

Even today, nausea and vomiting are two of the most distressing adverse effects associated with tumor therapy. The authors give an overview of the mechanism and the trigger factors (emetogenic potential of the chemotherapies, the patient risk factors, and the used antiemetic drugs) of nausea and vomiting. A short summary will describe the antiemetic drugs focusing on metoclopramide, steroid and the currently widely used setron therapy which is effective only during the acute phase of chemotherapy-induced nausea and vomiting (CINV). ⋯ The mechanism and the trigger factors of radiotherapy-induced nausea and vomiting (RINV) are different from CINV. For treatment of RINV metoclopramide (due to reimbursement regulation) and ondansetron can be used. In case of radio-chemotherapy the antiemetic treatment should follow the CINV guidelines.
