BACKGROUND Outcome data in young women with ductal carcinoma in situ (DCIS) are rare. The benefits of boost radiotherapy in this group are also unknown. We aimed to assess the effect of boost radiotherapy in young patients with DCIS. METHODS We included 373 women from 18 institutions who met the following inclusion criteria: having tumour status Tis and nodal status (N)0, age 45 years or youn...
BACKGROUND Radiotherapy is an important treatment of choice for breast cancer patients after breast- conserving surgery, and we compare the feasibility of using dual arc volumetric modulated arc therapy (VMAT2), single arc volumetric modulated arc therapy (VMAT1) and Multi-beam Intensity Modulated Radiotherapy (M-IMRT) on patients after breast-conserving surgery. MATERIALS AND METHODS Thirty ...
Management of ductal carcinoma in situ (DCIS) has evolved from radical surgery to the option of a more minimally invasive approach. Data show that breast conservation surgery performed with administration of radiotherapy, like mastectomy, is feasible and safe. Because efforts to find a safe group for elimination of radiotherapy have resulted in data that conflict, radiotherapy still remains sta...
positive lymph nodes, adjuvant radiotherapy to the breast or chest wall and regional lymph nodes is a standard treatment 1,2. To reduce local recurrence, basic oncologic principles dictate the inclusion of all potentially involved lymph nodes in the radiotherapy treatment fields. In locoregional breast treatment, conventional techniques for beam placement rely on anatomic landmarks seen on the ...
INTRODUCTION Correct target positioning is crucial for accurate dose delivery in breast radiotherapy resulting in utilisation of daily imaging. However, the radiation dose from daily imaging is associated with increased probability of secondary induced cancer. The aim of this study was to quantify doses associated with three imaging modalities and investigate the correlation of dose and varying...
BACKGROUND Radiation fibrosis is not easily measurable although clinical scores have been developed for this purpose. Biomarkers present an alternative more objective approach to quantification, and estimation in blood provides accessible samples. We investigated if blood cytokines could be used to measure established fibrosis in patients who have undergone radiotherapy for breast cancer. MET...
Patients with left-sided breast cancer are at risk of cardiac toxicity because of cardiac irradiation during radiotherapy with the conventional 3-dimensional conformal radiotherapy technique. In addition, many patients may receive chemotherapy prior to radiation, which may damage the myocardium and may increase the potential for late cardiac complications. New radiotherapy techniques such as in...
BACKGROUND The treatment of breast cancer involves a multidisciplinary approach in which radiotherapy plays a key role. AIM The conformity index and the homogeneity index are two analysis tools of a treatment plan using conformal radiotherapy. The purpose of this article is an analysis of these two parameters in the assessment of the treatment plans in 58 patients undergoing postoperative rad...
BACKGROUND Keloid is a hypertrophic scar that may arise within 6 months after injury in susceptible individuals. Different therapies like surgical excision, intralesional steroid injections, local application of pressure, or postoperative irradiation with x-rays or electrons are reported. Although an immediate starting of therapy after surgery is usually recommended, delayed radiotherapy may al...
