Post mastectomy adjuvant radiotherapy in breast cancer: a comparison of three hypofractionated protocols.
OBJECTIVES To compare three hypofractionated protocols in postmastectomy cancinoma breast in terms of local control, toxicity and work load. METHODS A total of three hundred patients suffering from cancer breast stage T2-4, N any were randomized into three arms after mastectomy. All the patients were treated with four fields on Co60 i.e. two tangential portals for chest wall, one anterior sup...
متن کاملProspective evaluation of skin toxicities in patients receiving post-mastectomy irradiation of chest wall, supra/infraclavicular and internal mammary nodes delivered by conventional versus intensity-modulated radiotherapy technique
Background To determine whether IMRT could decrease skin toxicities in patients undergoing PMRT of chest wall, supra/infraclavicular (SCV), and internal mammary nodes (IMN) as compared to conventional technique. Materials and Methods Between 2009 and 2013, 106 patients treated with IMRT and 138 treated with conventional technique were followed up regularly. The skin toxicities were graded acc...
متن کاملPost Mastectomy Adjuvant Radiotherapy in Breast Cancer: A Comparison of Cardiac Toxicity in Hypofractionated and Normal Fractionation Protocols
Background: Postoperative radiotherapy (RT) for breast cancer is an essential part of adjuvant cancer treatment. RT reduces the risk of local recurrence by 50% and the risk of breast cancer mortality by 16%. Hypo-fractionated regimens are increasingly being used as they involve fewer treatment sessions and, in terms of tumor control, the effects of conventionally fractionated and hypo-fractiona...
متن کاملIs VMAT Planning Feasible in Pediatric Neuroblastoma?
Aim: To do a dosimetric comparison between VMAT (Volumetric modulated arc radiotherapy) and 3DCRT (3-dimensional conformal radiotherapy) plans in pediatric abdominal neuroblastoma. Methods: 15 patients with high risk abdominal neuroblastoma, treated between January 2012 and December 2015, with 3DCRT were reviewed. For comparison purpose, VMAT plans were also made on the planning CT scans. Volum...
متن کاملDosimetric comparison for volumetric modulated arc therapy and intensity-modulated radiotherapy on the left-sided chest wall and internal mammary nodes irradiation in treating post-mastectomy breast cancer
BACKGROUND The aim of the study was to evaluate the dosimetric benefit of applying volumetric modulated arc therapy (VMAT) on the post-mastectomy left-sided breast cancer patients, with the involvement of internal mammary nodes (IMN). PATIENTS AND METHODS The prescription dose was 50 Gy delivered in 25 fractions, and the clinical target volume included the left chest wall (CW) and IMN. VMAT p...
