2 Breast cancer is the most common malignancy among U.S. women, with more than 200,000 new cases diagnosed annually (Jemal et al, CA Cancer J Clin 2004; 54: 8-29) (Siegel R, et al. CA Cancer J Clin 2012; 62: 10 29) 2
3 RT is indicated after BCS to improve local tumor control As current practice, at least 50 Gy are administered to the whole breast 3
4 Investigation of the breast doses using different breast external beam irradiation techniques New techniques are being employed for breast treatment Compromise between breast irradiation and undesired irradiation of the healthy tissues surrounding Radiological Protection Issue Patient Related 4
5 Different left breast irradiation techniques iplan BrainLab TPS: f-imrt, IMRT2 and IMRT5 Two calculation algorithms: PBC and imc RT linear accelerator Simulations of the clinac + HD120 MLC Validations in solid water phantoms MC Simulations of breast cancer treatments Comparison of the 3 irradiation techniques Comparison of the 3 calculation algorithms 5

22 PBC vs BEAMnrc MC imc vs BEAMnrc MC f-imrt 96,18% 98,71% IMRT2 97,32% 98,98% IMRT5 98,02% 98,45% Better agreement between imc and BEAMnrc 22
23 23
24 HDMLC successfully modeled to simulate RT treatments in fixed gantry mode for static and dynamic MLC Comparing the techniques: It is not straightforward that more complex techniques are better for the breast irradiation (e.g IMRT5 more low doses in the OAR) Comparing the algorithms: PBC seems to overestimate doses in the PTV (doses >45Gy) compared to imc and BEAMnrc MC, with differences up to 5Gy imc results with ~2% differences BEAMnrc MC Major differences between MC and PBC in higher doses in lung tissue The choice of the calculation algorithm used in clinical practice is of utmost importance for the accuracy of dose calculation in patients, especially if heterogeneities are present. 24
