Partial breast irradiation: ready for routine?

Abstract

Breast-conserving treatment is considered the standard therapy for most early-stage breast cancer and has given excellent results. That notwithstanding in the last years, several institutions are trying to revisit the adjuvant radiation treatment setting, especially with respect to possible changes in overall treatment time and target volume within the philosophy of modern partial breast irradiation. Up to date, no conclusive data are available on the possible role of partial breast irradiation in early-stage breast cancer but in this paper, we review the rationale and the researches currently being undertaken within the framework of this approach, trying to answer whether, in spite of the absence of the randomized evidence of the equivalence between whole and partial breast irradiation, could be already possible to suggest this treatment modality in the daily clinical practice, at least in some selected cases.
