Background and purpose: The incidence of breast cancer increases as patients age, elderly patients account for a large proportion. Due to the insufifcient systemic therapy, more complications and poorly physical condition, the prognosis of elderly patients is often worse than the younger. The aim of this study was to investigate the safety and tolerance with non-anthracyclin regimen as adjuvant chemotherapy in elderly breast cancer patients. Methods:From Nov. 2008 to Jan. 2012, 56 patients (≥65 years) after surgical excision were enrolled into this study. The patients were divided into two groups:TC and PC groups. Each patient received 4 or 6 cycles of chemotherapy of PC (175 and 600 mg/m2, respectively;n=21) or TC (75 and 600 mg/m2, respectively;n=35), administered intravenously every 3 weeks, as adjuvant chemotherapy. Radiation therapy (as indicated) and endocrine therapy, for patients with hormone receptor-positive disease, were administered after completion of chemotherapy. Results: In this study, 50 patients completed chemotherapy as plan, the proportion of two groups were above 90%. After a median follow-up of 33 months, the median disease-free survival(DFS) and overall survival(OS) were not reached. The relapse-free rate and survival rate were 89.5%and 100%in the PC regime group, which were 90.3%and 96.8%in the TC regime group. Major toxicities included:neutropenia, leucopenia, alopecia, nausea, vomiting and various degree of peripheral neuropathy. The incidence of gradeⅢ-Ⅳneutropenia was 76.2%in PC group vs 48.6%in TC group (P=0.044). The most common cause for withdrawing from treatment was to be unable to tolerate the adverse effects. Conclusion:Adjuvant chemotherapy with paclitaxel and cyclophosphamide is safe, tolerable and promising for elderly breast cancer patients.

OBJECTIVETo characterize the sites of distant recurrence and clinical outcomes in a cohort of Chinese patients with metastatic triple-negative breast cancer (TNBC).

METHODSOne hundred and thirty-four patients with metastatic TNBC treated at Cancer Hospital of CAMS from January 1999 to December 2007 were included in this study. The clinicopathological features and long-term survival of the patients were retrospectively analyzed.

RESULTSThe median age of the patients was 45 years. Most patients (72.7%) had a higher predilection for visceral metastasis and early recurrence within the first two years of follow-up. Six patients (4.5%) presented with stage IV disease, 14 patients were diagnosed with locoregional recurrence after mastectomy, 75 patients with distant metastases, and 45 patients with both locoregional recurrence and distant metastasis. The most common site of first recurrence was the lung, and 62(51.7%)of the patients had more than two sites of metastasis. By July 30, 2009, 75 patients died of breast cancer (56.0%). The median overall survival (OS) was 26.5 months [95% confidence interval (CI), 20.5 - 32.6 months]. The 1-, 3- and 5-year overall survivals (OS) were 80.9%,37.1% and 30.1%, respectively. The median overall survival time of 58 patients with single site of metastasis was 28.5 months, longer than that of patients with more than two sites of metastases. Patients whose initial distant recurrence was bone metastasis only (7 patients) had better prognosis, with a median OS of 84.2 months. The median OS (28.5 vs. 12.6 months, P = 0.0001) differed significantly between patients who received first-line chemotherapy and those who did not. Forty-five of the 96 patients with measurable disease achieved complete/partial response (CR/PR), 39 patients had stable disease (SD), and 12 patients had disease progression (PD). The median OS was 36.1 months in patients with CR/PR, 20.8 months with SD, and 14 months with PD, respectively. The median OS of patients with CR/PR was significantly longer than that of patients with SD/PD (P = 0.0108). Distant metastasis, first-line chemotherapy and clinical response were significantly related with OS by univariate analysis. Furthermore, first-line chemotherapy and the clinical response were demonstrated to be an independent prognostic factor by multivariate analysis.

CONCLUSIONSRecurrence risk and mortality are considerably higher in TNBC patients within the early years of follow-up. TNBC patients have a higher risk of multiple and visceral metastases, and poorer survival, which might attribute to its aggressive clinical behavior and lack of effective regimens. Our findings also suggest that chemotherapy can effectively improve the clinical outcome of those patients.

OBJECTIVEThe aim of this study was to evaluate the effect of anastrozole, a new generation aromatase inhibitor, on the lipid metabolism in postmenopausal Chinese women with early breast cancer, and observe the adverse reactions as well.

METHODSPostmenopausal women with early breast cancer patients took anastrozole 1 mg per day. The lipid profiles of total cholesterol, triglyceride, low density lipoprotein, and high density lipoprotein were assessed before taking the drug, 3 months, 6 months after taking medication, and later once a year, until the end of medication or follow-up. Patients taking lipid-lowering drugs were excluded. The adverse reactions during the process of taking medication was followed-up by telephone.

RESULTSTwo hundred and eighty-five postmenopausal breast cancer patients took part in the trial from Jan. 2003 to Jun. 2009. All patients had completed primary surgery and demonstrated a postmenopausal status. ER or PR positivity was confirmed by histopathology. Taking the medication from a minimum of one year to a maximum of 5 years, with a median time of 3.61 years. During the medication time, anastrozole significantly increased the levels of low density lipoprotein-cholesterol after 6 months of treatment, continuing to 5 years, from (3.08 ± 0.90) mmol/L to (3.59 ± 0.59) mmol/L, with a maximal increase of 18.2% higher than that before medication. Anastrozole significantly increased the levels of total cholesterol and high density lipoprotein-cholesterol after 1 years of treatment. Anastrozole significantly reduced the levels of triglycerides after 1 years of treatment. Anastrozole showed no significant effect on serum lipids in the patients with pre-existing hyperlipidemia. A more significant effect on blood lipids was observed in patients aged ≥ 60-years than that in patients less than 60 years of age. The rate of other adverse events were similar to that reported in foreign patients.

CONCLUSIONSFor the postmenopausal patients with breast cancer, taking anastrozole may lead to an abnormal lipid metabolism. Anastrozole significantly increases the levels of low density lipoprotein-cholesterol, total cholesterol and high density lipoprotein-cholesterol, and significantly reduces the level of triglycerides. The rate of other adverse events were similar to that reported in foreign patients. it is suggested that the blood lipid levels should be regularly assessed in patients with long-term anastrozole treatment. The rate of other adverse events similar to that reported with foreign patients, and patients tolerate this treatment well.

OBJECTIVETo explore the relationship between genetic polymorphisms in apurinic/apyrimidinic endonuclease (APE1) and ADP ribosyltransferase (ADPRT) and individuals' susceptibility to chronic benzene poison ing (BP).

METHODSA case-control study was conducted. One hundred and fifty-two B P patients and 152 workers occupationally exposed to benzene without poisoning manifestations were investigated. The mismatched bases combined to create restriction site with restrained fragment length polymorphism technique (CRS-RFLP) was used for detecting the single nucleotide polymorphisms (SNPs) at Asp148Glu of APE1 gene and Val762Ala of ADPRT gene.

RESULTSThere was no significant difference in the distribution of genotypes of APE1Asp148Glu and ADPRTVal762Ala between the patients and the control groups. Compared with individuals having genotype of APE1Asp148Glu T/T without habit of alcohol consumption, there was a 4.13 times increased risk of BP for the alcohol user with genotype of APE1Asp148Glu T/T (OR = 4.13, 95% CI: 1.07 - 15.85, P = 0.03). The analysis of Logistic regression showed that smoking may play some role in modifying the risk of cironic benzene poisoning (OR = 0.33, 95% CI: 0.14 - 0.75, P = 0.01).

CONCLUSIONThe genetic polymorphisms in APE1Asp148Glu, ADPRTVal762Ala are not related to the risk of BP. Potential interaction is found between alcohol consumption and polymorphism of APE1Asp148Glu. Further study is needed to elucidate this interaction.

Anthracycline-Taxane chemotherapy is widely used in neoadjuvant treatment for breast cancers. However, there is limited data reported in patients with triple negative breast cancer (TNBC). Here, we evaluated the pathologic responses and survival of neoadjuvant epirubicin and taxanes chemotherapy in patients with locally advanced TNBC to provide some useful information for clinical practice. A total of 43 patients with locally advanced TNBC were enrolled in this study. Patients were administered with epirubicin 75 mg/m(2) plus paclitaxel 175 mg/m(2) or docetaxel 75 mg/m(2) every 3 weeks for at least 2 cycles. The primary endpoint was pathologic complete response (pCR), which was defined as no residual invasive cancer, or only carcinoma in situ in both the excised breast and axillary lymph node, while relapse-free survival (RFS) and overall survival (OS) were secondary endpoints. Thirty-nine (90.7%) patients were at clinical stages IIB-IIIC. Thirty-seven (86%) completed 4-6 cycles of preoperative chemotherapy, and objective response rate (ORR) was 81.4% (35/43). Forty-two patients underwent radical surgery subsequently. The pCR rate was 14.3% (6/42). The most common adverse events in neoadjuvant chemotherapy were nausea/vomiting (88.4%, 38/43) and neutropenia (88.4%). After a median follow-up period of 34.0 months, 3-year RFS and OS rate was 53.6% and 80.1%, respectively. All events of recurrence and death occurred in non-pCR patients, in whom the 3-year RFS and OS rates were 44.3% and 76.6%, respectively. This study suggest that neoadjuvant chemotherapy with epirubicin plus taxanes has a relatively low pCR rate and high early recurrence risk in locally advanced TNBC, which indicates the necessity for more efficacious treatment. Further study is needed to validate these results.

To study the possibility of separation and culture of human umbilical cord blood adherent cell (HUCBAC), the umbilical cord blood CD34(+) cells were cultured in Dexter system in order to evaluate and observe the biological behavior of adherent cells in vitro. The results showed that all cells were cultured with Dexter system. By day 9-14 (at a median of 11.2 days), adherent cell colonies formed and reached their maximum at 15-22 days (mean 19.6 days), by day 28, all adherent cells spread over the bottom of Petri dish. By means of light microscopy, these cells were found to differentiate into three kinds of cells in culture of 28 days: fibroblast-liked cell, macrophage liked cell and small-round cells. The ratio of these three kinds of cells was 56.8%, 38%, 5.5% respectively. Cytochemistry assay revealed that the positive rate reached 100% in NSE stain and PAS stain; the adherent cell by ALP stain were shown 35% positive, but in POX stain the result was negative. Immunohistochemistry stain revealed that the positive rate of cord adherent cells for CD106, CD29, CD44, CD45, CD50, Fn, Ln, collagen IV etc reached 96%, 93%, 98%, 68%, 72%, 92%, 74%, 83% respectively. It is concluded there are hematopoietic adherent precursors in cord blood CD34(+) cells and the HUCBAC shows some biological behavior of hematopoietic stromal cells.
