Clinical efficacy of local targeted chemotherapy for triple-negative breast cancer

Background

The aim of the study was to evaluate the clinical efficacy of superselective intra-arterial targeted neo-adjuvant chemotherapy in the treatment of estrogen receptor (ER)-negative, progesterone receptor (PR)-negative, and human epidermal growth factor receptor 2 (HER2)-negative (triple-negative) breast cancer.

Patients and methods.

A total of 47 triple-negative breast cancer patients (29 at stage II, 13 at stage III and 5 at stage IV) were randomly assigned to two groups: targeted chemotherapy group (n=24) and control group (n=23). Patients in the targeted chemotherapy group received preoperative superselective intra-arterial chemotherapy with CEF regimen (C: cyclophosphamide [600 mg/m²]; E: epirubicin [90 mg/m²]; F: 5-fluorouracil [600 mg/m²]), and those in the control group received routine neoadjuvant chemotherapy with CEF. The duration of the treatment, changes in lesions and the prognosis were determined.

Results

The average course of the treatment was 15 days in the targeted chemotherapy group which was significantly shorter than that in the control group (31 days) (P<0.01). The remission rate of lesions was 91.6% in the targeted chemotherapy group and 60.9% in the control group, respectively. Among these patients, 9 died within two years, including 2 (both at IV stage) in the targeted chemotherapy group and 7 (2 at stage II, 4 at stage III and 1 at stage IV) in the control group.

Conclusions

As an neoadjuvant therapy, the superselective intra-arterial chemotherapy is effective for triple-negative breast cancer, with advantages of the short treatment course and favourable remission rates as well as prognoses.     

Short-term Intensive Neoadjuvant Chemotherapy Improving 10-year Survival for Patients with Stage Ⅱ and Operable Stage Ⅲ Breast Cancer

Objective To evaluate the 10-year curative effects of short-term intensive neoadjuvant chemotherapy for operable breast cancer. Methods A total of 510 patients with stagell and operable stagelll breast cancer were divided into group A (preoperative neoadjuvant chemotherapy 251 cases) and group B (postoperative adjuvant chemotherapy 259 cases). The patients in group A received short -term and intensive neoadjuvant chemotherapy for 4 weeks followed by modified radical mastectomy two weeks after the chemotherapy. The postoperative adjuvant chemotherapy began within two weeks after surgery. The same chemotherapeutic regimen was used for both groups. Results For stage III in group A the 5-year overall survival rate (OS) and disease-free survival rate (DFS) were 59.2% and 54.9% respectively which were higher than those in group B (28.3% and 20.8% respectively,P<0.05). The 10-year OS and DFS were 78.1% and 73.5% respectively for stage II in group A which were higher than those in group B (68.4% and 60.7%,P< 0.05). The 10-year OS and DFS were 42.3% and 40.4% respectively for stage III in group A which were higher than those in group B (20.4% and 18.4% respectively,P<0.05). Conclusion The results showed that intensive neoadjuvant chemotherapy can improve the 10-year survival for patients with stage II and operable stage III breast cancer.     

血清miR-30a水平与乳腺癌化疗敏感性的相关性

目的:探讨血清miR-30a水平对局部进展期乳腺癌患者新辅助化疗敏感性的预测价值。方法:纳入145例TNM分期为II-III期乳腺癌患者,根据实体瘤疗效评价标准（RECIST 1.0）将患者分为化疗敏感组（103例）和化疗抵抗组（42例）,通过实时荧光定量PCR检测患者初次化疗前血清miR-30a水平,并与健康人群进行比较。通过受试者工作特征曲线（receiver operating characteristic,ROC）确定血清miR-30a对化疗抵抗的预测价值和阈值,并分析化疗抵抗相关的独立危险因素。结果:与化疗敏感患者相比,化疗抵抗组中年龄大于40岁、T分期为T3-4期、TNM分期为III期患者比例更高,差异存在统计学意义（P＜0.05）。化疗敏感组患者血清miR-30a水平显著低于健康对照组（0.79±0.21 vs 1.24±0.36,P=0.004）,而化疗抵抗组患者血清miR-30a水平则低于化疗敏感组患者（0.34±0.12 vs 0.79±0.21,P＜0.001）。ROC曲线分析显示血清miR-30a对化疗抵抗的预测阈值为0.48,灵敏度81.2%,特异度76.5%,并且化疗抵抗组中血清miR-30a≤0.48的患者比例显著高于敏感组（71.4% vs 25.2%,P＜0.001）。多因素logistics回归分析显示,血清miR-30a≤0.48（OR=1.982,95%CI:1.672~2.583,P＜0.001）、TNM分期III期（OR=1.604,95%CI:1.123~2.084,P=0.001）是预测乳腺癌患者化疗抵抗的独立危险因素。结论:血清miR-30a水平能够有效预测局部进展期乳腺癌患者新辅助化疗疗效,有望成为预测乳腺癌化疗敏感性的有效生物标志物。     

Taxane-based chemotherapy enhances response to neoadjuvant treatment for stage II and III breast cancer

Reducing primary tumor volume is the main role of neoadjuvant chemotherapy for breast cancer. We evaluated the benefit of adding docetaxel to anthracyclin as neoadjuvant therapy. This study is a retrospective cohort analysis comparing the efficacy of neoadjuvant chemotherapy in patients subjected to docetaxel and epirubicin or 5-fluoruracil, epirubicin and cyclophosphamide combinations (DE and FEC group, respectively). The mean number of chemotherapy delivered was similar in both groups (P = 0.8). A total of 316 patients were treated (151 in FEC group and 165 in DE group). Primary endpoint was the clinical and pathological response to therapy. Breast conserving surgery rate was compared. In T1/2 staged patients, the complete clinical response rate was 7.5% in FEC group and 32% in DE group (P = 0.002), and the breast conserving surgery rate was 72 and 73% in FEC and DE groups, respectively (P = 0.9). In the subset of patients staged as T3 and T4a-c, objective response was higher in DE group (P < 0.0001 and P = 0.008, respectively). Breast conserving surgery rate was 38 and 63% in FEC and DE groups, respectively, in T3 staged patients and, 20.5 and 37% in T4a-c staged patients (P = 0.003 and 0.08). Despite the similar number of chemotherapy cycles delivered in both groups, the presence of microscopic axillary lymph node involvement after chemotherapy was less frequent in DE group. Neoadjuvant chemotherapy with DE combination is more effective in terms of clinical and pathological response propitiating higher breast conserving surgery rate than FEC combination in stage II and III breast cancer.

Response of Triple Negative Breast Cancer to Neoadjuvant Chemotherapy: Correlation between Ki-67 Expression and Pathological Response

Triple-negative breast cancers constitute about 15% of all cases, but despite their higher response to neoadjuvant chemotherapy, the tumors are very aggressive and associated with a poor prognosis as well as a higher risk of early recurrence. This study was retrospectively performed on 101 patients with stage II and III invasive breast cancer who received 6–8 cycles of neo-adjuvant chemotherapy. Out of the total, 23 were in the triple negative breast cancer subgroup. Nuclear Ki-67 expression in both the large cohort group (n=101) and triple negative breast cancer subgroup (n=23) and its relation to the pathological response were evaluated. The purpose of the study was to identify the predictive value of nuclear protein Ki-67 expression among patients with invasive breast cancers, involving the triple negative breast cancer subgroup, treated with neoadjuvant chemotherapy in correlation to the rate of pathological complete response. The proliferation marker Ki-67 expression was highest in the triple negative breast cancer subgroup. No appreciable difference in the rate of Ki-67 expression in triple negative breast cancer subgroup using either a cutoff of 14% or 35%. Triple negative breast cancer subgroup showed lower rates of pathological complete response. Achievement of pathological complete response was significantly correlated with smaller tumor size and higher Ki-67 expression. The majority of triple negative breast cancer cases achieved pathological partial response. The study concluded that Ki-67 is a useful tool to predict chemosensitivity in the setting of neoadjuvant chemotherapy for invasive breast cancer but not for the triple negative breast cancer subgroup.     

Effect of Neoadjuvant CAF Regimen on the Expression of BCSG1 in Breast Cancer

Objective： To evaluate the efficacy of neoadjuvant chemotherapy and explore a sensitive and objective way in the evaluation of neoadjuvant chemotherapy, the pathological changes and BCSG1 expression were studied by pathological and immunohistochemical method in breast cancer patients with CAF neoadjuvant chemotherapy （Cyclophosphamide, Adriamycin and Fluorouracil, CAF） and those without at the same period. Methods： Specimens were obtained from 34 breast cancer patients receiving neoadjuvant CAF regimen chemotherapy （CAF group） and 110 breast cancer patients not receiving neoadjuvant chemotherapy （control group）. The BCSG1 expression was detected by SP immunohistochemistry. Correlation between BCSG1 expression and pathological response to CAF neoadjuvant chemotherapy was analyzed. Results： Overall response rate to neoadjuvant chemotherapy was 79.4%. The strong cytoplasm expression of BCSG1 was significantly lower in CAF group than in control group （29.4% vs. 64.5%, P〈0.01）. In CAF group, the positive cytoplasm expression in partial response （PR） （grade Ⅱ） cases was significantly lower than that in no response （NR） （grade Ⅲ） cases （P=0.002）. Conclusion： Neoadjuvant chemotherapy of CAF regimen could decrease the nuclear expression of BSCG1 in breast cancer.     

Effect of Neoadjuvant Chemotherapy on Improvement of Surgical Resectibility and Survival of Patients with Stage ⅢA Non Small Cell Lung Cancer

Objective To assess the effect of neoadjuvant chemotherapy on surgical resectibility and surival in patients with stage III A non small cell lung cancer (NSCLC). Methods 42 patients with stage III A NSCLC were randomized to receive either two cycles chemotherapy followed by surgery (neoadjuvant chemotherapy group) or surgery alone (surgery alone group). All patients received four cycles chemotherapy after surgery. Results The overall response to chemotherapy was 42.9% (38.1% partial response and 4.8% complete response). Toxicity of chemotherapy was minor and consisted mainly of gastroenterological side effects and myelosuppression. Patients treated with neoadjuvant chemotherapy had estimated surgical resection rate of 95.2% (n=20) and a complete resection rate in 52.4% (n=11) compared to 66.7% (n=14) and 28.6% (n=6) respectively, for patients with surgery alone (P<0.05). None of the patients died from the operation. The median survival was 24.6 months in the neoadjuvant chemotherapy group as compared to only 10.8 months in the surgery alone group (P<0.05). The 2-year survival rate was 57.1% in the chemotherapy group as compared to 28.6% in the surgery alone group (P<0.05). Conclusion Neoadjuvant chemotherapy improves the surgical resectibility and increases the median survival and 2-year survival rate of patients with stage III A NSCLC. This study was supported by the Jiangsu Provincial Scientific and Technology Committee (BS200376).
