Authors' objectives: To assess the effectiveness of IORT as adjuvant or replacement treatment for the current standard treatment of breast cancer, in terms of recurrence, survival, cosmetic results and impact on quality of life; and to ascertain the safety of this procedure, in terms of acute and late toxicity.
Authors' recommendations: The results of studies that assess IORT as an alternative to an external-radiation booster dose indicate that this combination does not amount to an increase in terms of effectiveness and overall survival, nor does it entail a significant reduction in terms of safety with respect to conventional external radiation treatment. These results are drawn from studies of little methodological rigour, and there are no clinical trials that would go to confirm them. Administration of a single dose of IORT is associated with an incidence of recurrences and metastasis comparable to that of conventional treatment, and, despite showing low toxicity, does not improve the toxicity of conventional treatment to any significant degree. This evidence is based on a single RCT with certain limitations and on observational and descriptive studies, something that considerably reduces the validity of these results. Indeed, the results of the studies included give rise to important doubts regarding the possible replacement of conventional external radiotherapy by intraoperative radiation as the treatment of choice in patients with breast cancer in the initial stages.
