摘要： 目的 ·分析局部区域复发（ loco-regional recurrence，LRR）乳腺癌患者原发灶和 LRR病灶雌激素受体（ estrogen receptor， ER）、孕激素受体（ progesterone receptor，PR）、人类表皮生长因子受体 -2（human epidermal growth factor receptor-2，HER-2）和增殖细胞核抗原 Ki67状态的符合率及对后续治疗的影响。方法 ·回顾性分析 2009年 1月— 2018年 9月，在上海交通大学医学院附属瑞金医院乳腺疾病诊治中心接受乳腺癌手术治疗，随访发生单纯 LRR的乳腺癌患者。对原发灶和 LRR病灶进行 ER、PR、HER-2和 Ki67状态检测，分析两者之间的一致性及后续治疗的选择。结果 ·在 7 823例接受手术乳腺癌患者中，有 106例发生单纯 LRR，其中 56例患者 LRR病灶检测了 ER、PR、HER-2和 Ki67状态，其阳性率分别为 48.2%、25.0%、35.2%和 81.5%，与原发灶的符合率分别为 76.8%、76.8%、89.1%和 77.8%，κ值分别为 0.538、0.469、0.729和 0.402。共有 18例患者激素受体（ ER或 PR）（14例）和 /或 HER-2（6例）状态发生改变： 9例激素受体状态由阳性变为阴性，其中 4例未接受后续内分泌治疗； 4例患者 HER-2状态由阴性变为阳性，其中 1例接受后续抗 HER-2靶向治疗。结论 ·乳腺癌原发灶与 LRR病灶的 ER、PR和 Ki67存在中度一致性，而 HER-2的一致性较高；LRR病灶受体状态的改变会影响其后续治疗方案的选择。

Abstract:

Objective · To analyze the concordance rates of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor-2 (HER-2), and Ki67 statuses between the primary and loco-regional recurrence (LRR) lesions and its influence on the following treatment in breast cancer patients. Methods · The breast cancer patients undergoing surgery in Comprehensive Breast Health Center, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine January 2009 to September 2018, who were reported recurrence only in loco-regional site were retrospectively analyzed. ER, PR, HER-2, and Ki67 statuses were detected in primary and LRR lesions. Concordance rates and their influence on following treatment were further analyzed. Results · A total of 7 823 breast cancer patients received surgery, among whom 106 cases experienced LRR without distant metastasis. There were 56 patients having full information about ER, PR, HER-2, and Ki67 statuses of LRR lesions, with the positive rates of 48.2%, 25.0%, 35.2%, and 81.5%, respectively. Concordance rates of ER, PR, HER-2, and Ki67 between primary and LRR lesions were 76.8%, 76.8%, 89.1% and 77.8%, with κ values at 0.538, 0.469, 0.729, and 0.402, respectively. Hormone receptor (ER or PR) (14 cases) and/or HER-2 (6 cases) statuses were altered in 18 patients. The hormone receptor status changed positive to negative in 9 cases, of which 4 cases did not receive following endocrine therapy. The HER-2 status changed negative to positive in 4 patients, and 1 of them received following anti-HER-2 targeted therapy. Conclusion · The concordance rates between primary and LRR breast cancer lesions of ER, PR, and Ki67 are moderate, and the concordance rate of HER-2 is high. Changes in receptor status in LRR lesions may affect the choice of following treatment options.
