    ABSTRACT: The study aims to identify clinical and pathological factors predictive of disease-free survival (DFS) and overall survival (OS) in locally advanced breast cancer (LABC) patients who do not have a pathologic complete response (no-pCR) of primary tumor after neoadjuvant chemotherapy (NC) with vinorelbine/epirubicin (VE) intravenous combination regimen. Retrospectively reviewed data of LABC patients in our Hospital. 97 patients who had no-pCR after NC were identified and enrolled in the study. All patients were treated with three cycles of VE intravenous administration before operation. Local-regional radiotherapy was offered to patients after the completion of chemotherapy followed by hormone therapy according to hormone receptor status. Neoadjuvant chemotherapy consisting of intravenous vinorelbine 25 mg/m on day 1 and 8 plus epirubicin 60 mg/m on day 1 was administered every 3 weeks. The relationship of survival with clinical and pathological factors was evaluated. Univariate analysis (log-rank tests) and multivariate analysis (Cox regression analysis) were performed to identify independent predictors for DFS and OS. Study was analyzed with a median follow-up of 65 months. The 5-year rates for DFS and OS were 58.0 and 68.5 %, respectively. Multivariate analysis revealed that three factors such as the estrogen receptor expression before NC (pre-ER), Ki-67 expression after NC (post-Ki-67), and pathological response of primary tumor (pRT) were independent prognostic factors of LABC patients (pre-ER and pRT for DFS, all three for OS). The DFS at 5 years was 73.8 % for patients without both factors, 51.5 % for patients with any one of both factors, and 10.3 % for patients with both factors. The OS at 5 years was 90.5 % for patients without these three factors, 64.3 % for patients with any one of these three factors, and 30.8 % for patients with any two of these three factors. Patients with all three factors died within 3 years. In LABC patients with no-pCR, three factors independently predicted of survival and, without those three high-risk factors, patients had the promising outcome.

    ABSTRACT: Triple negative breast cancer (TNBC) is associated with high pathological complete remission (pCR) rate in neoadjuvant treatment (NAT). TNBC patients who achieve pCR have superior outcome than those without pCR. A meta-analysis was done to evaluate whether integrating novel approaches into NAT can improve the pCR rate in TNBC. Medical subject heading terms (Breast Neoplasm) and key words (triple negative OR estrogen receptor (ER) negative OR HER2 negative) AND (primary systemic OR neoadjuvant OR preoperative) were used to select eligible studies. Experimental arm in each study was considered as the testing regimen, and control arm was defined as the standard regimen in this meta-analysis. A total of 11 studies with 14 paired regimens were included in the final analysis. Aggregate pCR rate was 37.3% and 44.6% in the standard and testing group, respectively. Novel approaches in the testing regimen significantly improved the pCR rate in NAT of TNBC patients compared with the standard regimen, with an odds ratio (OR) of 1.34 (95% confidence interval (CI) 1.11-1.62, P = 0.002). Considering specific regimens, we demonstrated the pCR rate to be much higher in the carboplatin-containing (OR = 1.80, 95% CI 1.39-2.32, P<0.001) or bevacizumab-containing regimens (OR = 1.36, 95% CI 1.11-1.66, P = 0.003) than in the control regimens. The addition of carboplatin in NAT had a pCR rate as high as 51.2% in TNBC patients, with an absolute pCR difference of 13.8% as compared with control regimens. No significant heterogeneity was identified among studies evaluating the addition of carboplatin or bevacizumab efficacy in NAT. This meta-analysis indicates that these novel NAT regimens have achieved a significant pCR improvement in TNBC patients, especially among patients treated with carboplatin-containing or bevacizumab-containing regimen. This can help us design appropriate trials in the adjuvant setting and guide clinical practice.

    ABSTRACT: To compare the sensitivity of mammogram and breast dedicated MRI in detecting ductal carcinoma in situ with microinvaion (DCIS-MI) and ductal carcinoma in situ (DCIS) lesions, and to further investigate the independent predictive factors of mammogram and MRI sensitivity. From August 2009 to November 2011, 122 consecutive confirmed breast cancer patients who had received operations were recruited for this clinical research. These patients were divided into two groups including DCIS (72 cases) and DCIS-MI (50 cases) based on pathologic reports. All the patients were female, with mean ages of 52.6 years and 54.4 years. Preoperative bilateral breast mammogram, breast dedicated MRI depictions and reports as well as histopathological reports were collected. Sensitivity of MRI outstood mammogram in each subgroups: 84.7% vs. 42.4% in DCIS (χ(2) = 27.028, P = 0.000), 94.0% vs. 80.0% in DCIS-MI group (χ(2) = 4.540, P = 0.040). And further analysis showed that MRI was more sensitive to high nuclear grade DCIS and DCIS-MI lesions than low nuclear grade ones (OR = 3.471, P = 0.031). of logistic regression analysis proved microcalcification was an independent predictive factor of mammogram sensitivity (OR = 11.287, P = 0.001). Sensitivity of breast dedicated MRI is superior to mammogram in detecting DCIS and DCIS-MI groups. Lesions with microcalcifiation is an independent predictive marker which meant that mammogram would achieve high detection rate in cancers presented calcification on mammogram image when compared with non-calcification. Diagnostic performance of breast MRI is less affected by clinical and pathological characteristics of the early stage breast cancer patients but further increased detection rate is observed in DCIS and DCIS-MI with high nuclear grade lesions which indicated that MRI could detect more early stage cancers with relative more aggression biological behaviour and provide these patients with early surgical interventions before possible progression to invasive breast cancers.

    ABSTRACT: To investigate the clinicopathological characteristics and prognosis of breast cancer subtypes classified by quantitative estrogen receptor (ER), progesterone receptor (PR), and Her2. 923 patients with primary breast cancer having a median age of 53 years who were treated at the Cancer Hospital of Fudan University in Shanghai between January 2002 and June 2004 were retrospectively analyzed. Four molecular subtypes were constructed from the immunohistochemical results of quantitative hormone receptor (HR) and Her2 status. HR+ was defined as ER+ and PR+, HR+/- as ER/PR+ at lower levels or lacking either ER or PR, and HR- as both ER- and PR-. The four subtypes were HR+/Her2-, HR+/-/Her2-, HR-/Her2- (triple-negative), and Her2+. Clinical and pathological parameters, disease-free survival (DFS), and overall survival (OS) measurements were compared between patients with different molecular subtypes. The proportions of HR+/Her2-, HR+/-/Her2-, triple-negative, and Her2+ breast cancer were 36.6% (338/923), 22.9% (211/923), 20.6% (190/923), and 19.9% (194/923). The median follow-up was 49.0 months (4-77 months). In 145 cases disease recurrence or death occurred. In multivariate analysis with the HR+/Her2- subtype taken as the reference category, triple-negative and Her2+ subtypes were associated with increased recurrence and death with a hazard ratio (HR) of 2.05 (95% CI 1.31-3.20; P = 0.002) and 1.89 (95% CI 1.20-2.97, P = 0.006) for DFS and 2.84 (95% CI 1.45-5.55; P = 0.002) and 2.95 (95% CI 1.51-5.77, P = 0.002) for OS, respectively; the HR+/-/Her2- subtype was marginally associated with poor prognosis with HR 1.51 (95% CI 0.94-2.43; P = 0.088) and 1.90 (95% CI 0.92-3.94; P = 0.084) for DFS and OS, respectively. Breast cancer subtypes based on quantitative ER, PR, and Her2 may be predictive of prognosis. Patients whose tumors were not HR+/Her2- had a worse outcome in our study.

    ABSTRACT: To examine the effect of postoperative pregnancy upon the prognosis of young Chinese breast cancer patients. Four hundred and thirty-two female unilateral breast cancer patients aged 35 or younger were retrospectively reviewed. Kaplan-Meier analysis and Log Rank test were used for univariate analysis of factors predictive of disease-free survival (DFS) and overall survival (OS). Multivariate analysis was carried out using the Cox proportional hazards model. Eighteen patients were identified to have postoperative pregnancy, including 5 full-term pregnancy and 13 abortions with the earliest pregnancy taking place at Month 17 post-operation. After a median follow-up of 62 months (6 - 237 months), the DFS and OS rates were 72.5% (313/432) and 88.7% (383/432) respectively. On multivariate analysis, postoperative pregnancy, clinical stage and number of pathologically involved axillary lymph node were significantly associated with DFS. And the axillary lymph node status was also predictive of OS. No death occurred in patient with postoperative pregnancy. There was no significant association between postoperative pregnancy and OS. Postoperative pregnancy has no adverse effect upon the prognosis of young breast cancer patients.

    ABSTRACT: To identify predictive markers of the long-term outcome for neo-adjuvant chemotherapy (NC) in locally advanced breast cancer (LABC) treated with intravenous vinorelbine (V) and epirubicin (E) combination regimen. One hundred and nineteen patients with LABC were treated from September 2001 to May 2006. All patients were diagnosed as invasive breast cancer by 14G core needle biopsy and treated with three cycles of VE regimen before the operation. The patients were subjected to surgery and subsequently were given other three cycles of VE or cyclophosphamide+epirubicin+fluorouracil (CEF) regimen according to the clinical responses. Local-regional radiotherapy was applied to all patients after the chemotherapy and followed by hormone-therapy according to hormone receptor status. The impact of clinical, pathological, and immunohistochemical features on disease free survival (DFS) and overall survival (OS) was evaluated. All patients were evaluable for responses: clinical complete response was documented in 27 patients (22.7%), 78 patients (65.5%) obtained partial clinical response. The pathological complete response was found in 22 cases (18.5%). Of the patients, 115 cases (96.6%) were followed-up for a median time of 63.4 months (range, 9-76 months), the 5-year DFS rate and OS rate was 58.7% and 71.3%, respectively. On multivariate analysis, high pre-Ki-67 (P=0.012) and post-Ki-67 expression (P=0.045), no pathological complete response after NC (P=0.034) were associated with the higher risk of disease relapse; high pre-Ki-67 (P=0.017) and post-Ki-67 expression (P=0.001), negative pre-ER (P=0.002) and no pathological complete response after NC (P=0.034) were associated with a shorter survival. Pathological response in primary tumor, pre-Ki-67 and post-Ki-67 expression, pre-ER expression are important predictors of long-term outcome for LABC patients with three cycles of VE regimen before operation.
