Abstract P1-10-10: Risk factors of locoregional recurrence, locoregional failure pattern and role of postmastectomy radiotherapy for T1-2 breast cancers with 1-3 positive axillary lymph nodes

Conclusions: Pure residual LVI after neoadjuvant chemotherapy is a rare event. Our findings show that the outcome associated with residual LVI, with or without residual cancer in nodes, might not be as dismal as previously reported, although longer follow-up will be required. The more favorable outcome observed is in contrast to the single study previously published. Although the difference may be due to details in the type of chemotherapy or stage at presentation, it is difficult to compare the 2 groups of patients due to limited information about the earlier cases. More data is needed to draw conclusions on the prognostic significance of this type of residual disease. The lack of a current AJCC/UICC T category for this finding will make identification of these patients difficult in large databases.Citation Format: Wang S, Peng R, Jin J, Wang W, Song Y, Liu Y, Liu X, Yu Z, Fang H, Ren H, Li Y.
