[Abstract] Objective This paper tries to investigate the clinical value of topoisomerase Ⅱα (TOPOⅡα) combined with Ki67 in predicting the efficacy of neoadjuvant chemotherapy for triple negative breast cancer. Methods A retrospective analysis of 82 cases of triple negative breast cancer from January 2013 to December 2016 was carried out, and all of whom received anthracycline combined with paclitaxel neoadjuvant chemotherapy, aiming to investigate the relationship between the expression of TOPO II and Ki67 and the efficacy of chemotherapy. Results The whole pCR rate was 20.7% (17/82) among the 82 patients with triple negative breast cancer; the high expression rate of TOPOⅡαwas 42.6% (35/82), pCR rate was 25.7% (9/35), higher than the low expression rate of pCR of 17.0%(8/47), the difference was not statistically significant (P>0.05); high expression rate of Ki67 was 67.1% (55/82), pCR rate was 25.4% (14/55), higher than the low expression rate of 11.1% (3/27), the difference was not statistically significant (P>0.05); pCR rate reached 53.53%(8/19) when TOPOⅡαand Ki67 with high expression rate, significantly higher than that of the overall rate of pCR, the difference was statistically significant (P<0.01). Conclusion TOPOⅡα combined with Ki67 expression has predictive value for neoadjuvant chemotherapy in triple negative breast cancer, which can provide reference for individualized treatment after operation.

目前,乳腺癌已進入分類治療時代,三陰性乳腺癌(TNBC)因無治療性靶點,主要治療手段仍是化療。雖然整體療效較差,但部分患者對化療敏感,表現(xiàn)出與管腔(Luminal)A型相似的良好預(yù)后[1]。該研究通過檢測化療前組織標(biāo)本TOPOⅡα及Ki67表達(dá),探討其預(yù)測三陰性乳腺癌新輔助化療療效的應(yīng)用價值,以期為臨床床選擇治療方式及臨床評價手段提供參考,現(xiàn)報道如下。
