Indications potentielles de la tomothérapie hélicoïdale dans les cancers du sein

Use of helical tomotherapy in locally advanced and/or metastatic breast cancer for locoregional treatment

“…In each case, the use of HT improved at least one conformity index, and gave a more homogeneous dose to the target volume with better sparing of OAR. 13 In our institute, HT utilization rates are increasing annually with 0.8% usage in 2009, rising to 9.4% in 2016 as the indications broaden along with clinical experience. 35 At present, in view of our research, the current indications of HT are bilateral breast cancer with regional lymph nodes, deep IMN and in patients with particular anatomical shapes with known difficulty in obtaining adequate coverage with a classic field-in-field technique (especially funnel chest).…”

“…[9][10][11][12] Thus, HT can obtain a dosimetric gain in complex volumes with respect to the planning target coverage and sparing of organs at risk. 13,14 This was shown in a study evaluating locoregional radiation in the setting of left breast cancer, where a significant reduction in the left lung and heart doses were demonstrated along with an improvement in the conformity index. 15 The purpose of this work was to assess the feasibility and evaluate the toxicity of this promising tool for locally advanced and metastatic breast cancer.…”
