In preclinical studies, celecoxib has been associated with reduced risk of breast cancer. In this study, the aim was to assess the biomodulatory effect of celecoxib on blood and benign breast tissue biomarkers in women at increased risk for breast cancer. Women at increased risk for breast cancer [5-year Gail risk score of >1.67%, history of atypical hyperplasia, lobular carcinoma in situ, or previous estrogen receptor (ER)-negative breast cancer] were treated with celecoxib at 400 mg orally twice daily for 6 months. Participants underwent random periareolar fine needle aspiration and blood draw at baseline and at 6 months for analysis of biomarkers: serum levels of insulin-like growth factor 1 (IGF-1), IGF-binding protein 1 (IGFBP-1), and IGFBP-3; tissue expression of Ki-67 and ER; as well as cytology. Forty-nine patients were eligible for analysis. Median IGFBP-1 levels increased significantly from 6.05 ng/mL at baseline to 6.93 ng/mL at 6 months (P = 0.04), and median IGFBP-3 levels decreased significantly from 3,593 ng/mL to 3,420 ng/mL (P = 0.01). We also detected favorable changes in cytology of 52% of tested sites after 6 months of celecoxib therapy. No changes in tissue Ki-67 and ER expression levels were observed. No grade 3 or 4 toxicity was recorded. Celecoxib was well tolerated and induced favorable changes in serum biomarkers as well as cytology in this pilot phase II trial. A phase IIb placebo-controlled study with celecoxib could be considered for women at increased risk for breast cancer.

塞来考昔用于乳腺癌高危女性化学预防的生物标志物调节研究:II 期试点研究

在临床前研究中,塞来昔布与降低患乳腺癌的风险有关。在这项研究中,目的是评估塞来昔布对乳腺癌风险增加的女性的血液和良性乳腺组织生物标志物的生物调节作用。乳腺癌风险增加的女性 [5 年 Gail 风险评分>1.67%,有非典型增生史、原位小叶癌或既往雌激素受体 (ER) 阴性乳腺癌] 接受两次口服 400 mg 塞来昔布治疗每天 6 个月。参与者在基线和 6 个月时接受了随机乳晕周围细针抽吸和抽血,以分析生物标志物:血清胰岛素样生长因子 1 (IGF-1)、IGF 结合蛋白 1 (IGFBP-1) 和 IGFBP- 3; Ki-67和ER的组织表达;以及细胞学。49 名患者符合分析条件。IGFBP-1 水平中值从基线时的 6.05 ng/mL 显着增加到 6 个月时的 6.93 ng/mL (P = 0.04),IGFBP-3 水平中值从 3,593 ng/mL 显着下降到 3,420 ng/mL (P = 0.01) ). 在塞来昔布治疗 6 个月后,我们还检测到 52% 的测试部位的细胞学发生了有利变化。未观察到组织 Ki-67 和 ER 表达水平的变化。没有记录到 3 级或 4 级毒性。塞来昔布耐受性良好,并在该 II 期试验试验中诱导了血清生物标志物和细胞学的有利变化。对于乳腺癌风险增加的女性,可以考虑使用塞来昔布进行 IIb 期安慰剂对照研究。中位 IGFBP-3 水平从 3,593 ng/mL 显着下降至 3,420 ng/mL (P = 0.01)。在塞来昔布治疗 6 个月后,我们还检测到 52% 的测试部位的细胞学发生了有利变化。未观察到组织 Ki-67 和 ER 表达水平的变化。没有记录到 3 级或 4 级毒性。塞来昔布耐受性良好,并在该 II 期试验试验中诱导了血清生物标志物和细胞学的有利变化。对于乳腺癌风险增加的女性,可以考虑使用塞来昔布进行 IIb 期安慰剂对照研究。中位 IGFBP-3 水平从 3,593 ng/mL 显着下降至 3,420 ng/mL (P = 0.01)。在塞来昔布治疗 6 个月后,我们还检测到 52% 的测试部位的细胞学发生了有利变化。未观察到组织 Ki-67 和 ER 表达水平的变化。没有记录到 3 级或 4 级毒性。塞来昔布耐受性良好,并在该 II 期试验试验中诱导了血清生物标志物和细胞学的有利变化。对于乳腺癌风险增加的女性,可以考虑使用塞来昔布进行 IIb 期安慰剂对照研究。塞来昔布耐受性良好,并在该 II 期试验试验中诱导了血清生物标志物和细胞学的有利变化。对于乳腺癌风险增加的女性,可以考虑使用塞来昔布进行 IIb 期安慰剂对照研究。塞来昔布耐受性良好,并在该 II 期试验试验中诱导了血清生物标志物和细胞学的有利变化。对于乳腺癌风险增加的女性,可以考虑使用塞来昔布进行 IIb 期安慰剂对照研究。
