Significant Difference

CRA532 Background: The purpose of the study was to compare treatment outcomes in patients with breast cancer treated with partial breast irradiation and of those treated with whole breast radiation therapy. Methods: We conducted a systematic review and meta-analysis of published. Randomized clinical trials comparing partial breast irradiation versus whole breast radiation therapy. Primary outcome was overall survival and secondary outcomes were locoregional, distant and supraclavicular recurrences. Results: A search of the literature identified 3 trials with pooled total of 1,140 patients. We found no statistically significant difference between partial and whole breast radiation arms associated with death (OR 0.912, 95% CI 0.674–1.234, p = 0.550), distant metastasis (OR 0.740, 95% CI, 0.506–1.082, p = 0.120), or supraclavicular recurrences (pooled OR 1.415, 95% CI 0.278–7.202, p = 0.560). However, partial breast irradiation was statistically significantly associated with an increased risk of both local (pooled OR 2.150, 95% CI, 1.396–3.312; p = 0.001) and regional disease recurrences (pooled OR 3.430, 95% CI, 2.058–5.715; p < 0.0001) compared with whole breast radiation. Conclusions: Partial breast irradiation does not jeopardize survival and may be used as an alternative to whole breast radiation. Nevertheless, the issue of locoregional recurrence needs to be further addressed. No significant financial relationships to disclose.
