Helical tomotherapy with a complete-directional-complete block technique effectively reduces cardiac and lung dose for left-sided breast cancer.

CONCLUSIONS: HT with the CDCB technique is feasible for treating left-sided breast cancer patients. The CDCB10 and CDCB20 techniques not only achieved similar planning target volume coverage, homogeneity and dose conformity but also allowed better sparing of the heart and bilateral lungs. ADVANCES IN KNOWLEDGE: For left-sided breast cancer patients whose regional nodal irradiation field includes the internal mammary node, heart avoidance is an important issue. The CDCB technique achieved good planning target volume coverage, homogeneity and dose conformity and allowed better sparing of the mean dose of the lung, the left anterior descending artery, and the heart and reduced the V30 of the heart.
