Abstract
e14603 Background: Zoledronic acid (ZOL) can reduce the risk of skeletal-related events (SREs) and may have direct and indirect antitumor effects, which have been shown in animal models, pilot clinical studies as well as in recent phase III randomized trials. However, the pharmacokinetics of the drug in breast cancer patients remains to be elucidated and optimized. The purpose of this randomized study was to compare the effects of ZOL on osteoclasts and angiogenesis between a weekly low-dose versus a conventional dosage. Methods: Sixty breast cancer patients with bone metastases were recruited in this randomized phase II clinical study. The participants either received ZOL 1mg IV weekly for 4 doses or a single dose of ZOL 4mg IV. No other antitumor treatments were administered. During the first month after initial infusion of ZOL, serial blood samples were collected on day 1, 15 and 29 measuring markers for bone resorption (NTx), angiogenesis (VEGF), and tumor burden (CEA and CA15–3). Results: Compared to a single-dose administration, weekly low dose of ZOL resulted in a greater reduction in serum levels of VEGF and NTx, with a significant trend over time during one month observation. There were no statistically significant differences in circulating levels of CEA and CA15–3 between the two dosing regimens. Patients who received metronomic ZOL had a longer median time to disease progression (TTP) (7.0 months, 95%CI, 6.1–7.9 months) than those who had a single dose of ZOL (2.8 months, 95%CI, 0–5.7 months; p=0.076). Conclusions: The metronomic use of low-dose ZOL 1 mg appeared to be more effective than the conventional regimen in the long-lasting reduction of VEGF and NTx, and in prolonging TTP. This dosing schedule should be further assessed in phase III trials as we demonstrated that ZOL 1mg has greater antitumor properties in our study. No significant financial relationships to disclose.

Abstract
e22204 Background: Breast cancer patients with nipple discharge (ND) may constitute a distinct clinical entity compared to those without ND, which has not been well elucidated in previous reports. We sought to analyze the demographic features and prognostic profiles of breast cancer patients presenting with nipple discharge in Chinese population. Methods: A total of 3234 patients, categorized as ND (2.47%) and non-nipple discharge (NND; 97.53%) according to different initial signs, were retrospectively analyzed. Survival curves were performed with Kaplan-Meier method and annual recurrence hazard was estimated by hazard function. Results: ND group tended to have smaller tumors and less axillary lymph node (ALN) involvement than NND group (P < 0.05). In the univariate analysis, we found significantly different recurrence-free survivals (RFS) between subgroups (P = 0.0182), with the rate of 77.78% for ND group and 72.46% for the other at the 11th year respectively. In Cox proportional hazards regression analysis, we found that tumor size (P < 0.001), ALN status (P < 0.001) were independent prognostic factors for RFS. To further evaluate whether prognostic effect of ND status remained unabated over time, the test for lack of proportionality was performed. However, it was statistically significant (global test, P = 0.039), which hinted at a demand for the employment of Cox non-proportional hazards regression in this analysis. In time dependent Cox model, ND status (P = 0.0495) as well as ERBB2 status (P = 0.017), tumor size (P < 0.001), ALN status (P < 0.001) were independent prognostic factors when ND and ERBB2 status were taken as time-varying covariates. Annual hazard rates for recurrence remained lower on ND group until approximately 4.5 years after surgery, while the situation was just the opposite thereafter. Conclusions: Our findings suggested that demographic features and prognostic profiles were quite different between breast cancers presenting with and without ND in Chinese population, which may indirectly uncover distinct biological behaviors and potentially enlighten novel therapeutic approaches for patients with different initial signs. No significant financial relationships to disclose.

Abstract
Olfactory nerve axons terminate in olfactory bulb glomeruli forming excitatory synapses onto the dendrites of mitral/tufted (M/T) and juxtaglomerular cells, including external tufted (ET) and periglomerular (PG) cells. PG cells are heterogeneous in neurochemical expression and synaptic organization. We used a line of mice expressing green fluorescent protein under the control of the glutamic acid decarboxylase 65-kDa gene (GAD65+) promoter to characterize a neurochemically identified subpopulation of PG cells by whole cell recording and subsequent morphological reconstruction. GAD65+ GABAergic PG cells form two functionally distinct populations: 33% are driven by monosynaptic olfactory nerve (ON) input (ON-driven PG cells), the remaining 67% receive their strongest drive from an ON-->ET-->PG circuit with no or weak monosynaptic ON input (ET-driven PG cells). In response to ON stimulation, ON-driven PG cells exhibit paired-pulse depression (PPD), which is partially reversed by GABA(B) receptor antagonists. The ON-->ET-->PG circuit exhibits phasic GABA(B)-R-independent PPD. ON input to both circuits is under tonic GABA(B)-R-dependent inhibition. We hypothesize that this tonic GABA(B)R-dependent presynaptic inhibition of olfactory nerve terminals is due to autonomous bursting of ET cells in the ON-->ET-->PG circuit, which drives tonic spontaneous GABA release from ET-driven PG cells. Both circuits likely produce tonic and phasic postsynaptic inhibition of other intraglomerular targets. Thus olfactory bulb glomeruli contain at least two functionally distinct GABAergic circuits that may play different roles in olfactory coding.

Abstract #6152
Objective: Comparative studies on clinical features and outcomes of very rare invasive micropapillary carcinoma of breast cancer of 4 subtypes by immunohistochemistry staining.
 Methods: From Aug 2005 to Mar 2008, a total of 52 breast cancer patients(BCPs) with an invasive micropapillary component (IMPC) among 1951 Chinese BCPs with complete of clinicopathologic data in our institution were enrolled into a retrospective analysis. We characterized all these 52 patients and analyzed using various parameters.
 Results: The 52 cases of breast carcinoma with an IMPC all occurred in women. Mean age was 51 years (range from 26-82). All of these patients had breast masses; one also had metastasis to the supraclavicular lymph node at the time of diagnosis., mean tumor size was 2.83cm(T2), 23.08%(12/52) was pure invasive micropapillary carcinoma, and lymph node positive percentage was 75.59 %( 36/51).Fifty one patients received surgery, while one of them lost the chance of surgery. Forty of them received the modified mastectomy while one was performed lumpectomy due to old age. One was performed LAND alone and four were performed lumpectomy and sentinel lymph node biopsy.
 By using IHC staining, when we regard HER2/neu 0 and +as negative. The Luminal A group, Luminal B, trip-negative, HER2+ /ER- were 76.92% (40/52), 11.54 %( 6/52), 7.69 %( 4/52), 3.85 %( 2/52), respectively. Compared to the database of 2005 breast cancer carcinoma in our institution, there was more Luminal A group patients than the whole group (P=0.01, chi-square test.), more Luminal B (P=0.028, Fisher exact possibility test), less trip-negative group (P=0.001, chi-square test). The positive lymph node among the Luminal A group, Luminal B, trip-negative, HER2+ /ER- were 65%,80%, 100%, 100%, respectively, while the lymphvascular invasion were 55%,33.33%,50%,50%,respectively, Mulifocality in Luminal A was 25% , 16.67% in Luminal B , while 50% in both trip-negative and HER2+/ER-.
 Twenty-one of them received both anthracyclines and Taxane, while 27 only received anthracyclines, Four patients only were received only AIs due to old age. All the luminal group patients received endrocine therapy after chemo. After nearly 14 months (2∼34 months) follow up, thirty-six women were disease free, one had local recurrence, and 1 had lung metastasis, while 1 had ovary carcinoma when the diagnosis of breast malignant, one patient lost following up due to mental disorder. Among the luminal B, one had metastasis when diagnosis, others were disease free. One woman of the trip-negative died of non-breast cancer disease,the HER2+/ER- group was no recurrence or metastasis.
 Discussion: The prelimary results showed that more luminal group in the IMPC may get benefit from the endocrine therapy. However the number of these cases is small and follow-up time is not very long, further studies are necessary to explain these rare and unique pattern of invasive carcinoma.

Abstract #4085
Background:. Seroma formation is one of the most common complications after breast cancer surgery including modified radical mastectomy and breast conservative surgery. Our study aims to investigate the risk factors of postoperative seroma in Chinese breast cancer patients.
 Methods: Clinical data of 158 women who underwent surgerical therapy for breast cancer in our hospital were collected prospectively and all patients were followed up. The risk factors for seroma occurrence were compared between the seroma group and control group using X 2 test or t test, as well as the logistic regression was used as multivariate analysis.
 Results: Univariate analysis showed that the average age of the seroma group was significantly higher than those without seroma formation(58.71vs51.00, P=0.0019), but the total serum protein and albumin content were lower (68.47g/L vs 72.53g/L, P=0.009 and 40.75g/L vs 42.52g/L,P=0.020, respectively). In seroma group, the drainage volume of the first three days, the total and daily drainage volume were all higher (all p values less than 0.01), as well as drainage duration and hospital stay were longer(8.3d vs 14.4d, P=0.000 and 11.5d vs 23.7d, P=0.000, respectively). Logistic regression showed that older patients (OR=1.080, 95%CI 1.016∼1.148, P=0.013), lower total serum protein content(OR=0.814, 95%CI 0.705∼0.940, P=0.005)and higher drainage volume in d1(OR=1.009, 95%CI 1.001∼1.016, P=0.022) and d3 (OR=1.017, 95%CI 1.005∼1.029, P=0.005) were all independent risk factors for subcutaneous seroma. The daily average drainage curve showed a gradually decreasing trend with a highest collections in the first three days. The seroma group had significantly higher average daily drainage volume( P=0.034) and longer duration (P=0.000).
 Conclusion:The risk factors of seroma formation after breast cancer surgery are complicated. However in order to prevent its occurrence effectively, the factors including age, nutrition status and daily drainage volume should be taken into consideration.

Abstract #6080
Background: Triple negative breast cancers are defined by a lack of expression of estrogen, progesterone, and Her-2 receptors. A number of studies suggested that the triple-negative phenotype could contribute to an aggressive behavior and a poor prognosis. However, similar data is still not available for Chinese populations. We sought to analyze the clinicopathological features of this subgroup in our hospital in order to get characteristics for Chinese breast cancer.
 Methods: We performed a retrospective study of 2028 female unilateral breast cancer patients undergoing surgery in our hospital from February 1991 to December 2003. ER, PR and Her-2 status were assessed using immunohistochemical staining. Survival curves were performed with Kaplan-Meier method and annual recurrence hazard was estimated by hazard function.
 Results: According to different combinations of hormone receptor (HR) and Her-2 status, 2028 patients were categorized into the three subgroups as follows: Her-2+ (32.25%), HR+/Her-2- (48.92%) and triple-negative (18.83%). Triple-negative tumors were larger (greater than 2 cm in diameter) than HR+/Her-2- tumors, but smaller than Her-2+ tumors (70.03%, 66.15% and 76.15% respectively, P < 0.001). In addition, 21.99% of patients whose tumors were triple-negative had four or more axillary nodes involved compared with 27.37% of patients with Her-2+ tumors and 22.78% with HR+/Her-2- tumors (P = 0.004). There were statistical differences in the distribution of TP53 mutation and Cathepsin-D status (P < 0.001 for both). In the univariate analysis, we found a statistical significance for recurrence-free survival (RFS) among the three subgroups (P = 0.0036), with the rate of 72.89% for Her-2+ tumors, 78.26% for HR+/Her-2- tumors and 75.61% for triple-negative tumors at the 11th year respectively. When it came to the time of hazard peaks, discrepancies existed in different subgroups. Triple-negative patients showed an early major recurrence surge peaking at the 2.5th year after surgery, followed by a gradual decline until year 6.5 and then a modest increase. As to HR+/Her-2- patients, the hazard plot exhibited a wide initial plateau-like wave covering at least 4 years and a subsequent rise. The hazard rate for Her-2+ patients displayed a tapering sharp at the 1st year and a second rise. Furthermore, the first peak of triple-negative tumors was higher than that of HR+/Her-2- patients, but lower than that of Her-2+ ones.
 Conclusions: The recurrence pattern for triple-negative tumors was intermediate between Her-2+ and HR+/Her-2- counterparts.Our findings suggested that biological characteristics and prognosis of Chinese triple-negative breast cancer might be more favorable and somewhat different from those in Western populations.

Abstract #3098
[Background and purpose] Although glutathione S-transferase M1 (GSTM1) enzyme occupies a key position in biological detoxification processes by catalyzing the glutathione conjugation of carcinogens, GSTM1 gene is genetically deleted (referred as GSTM1-null or GSTM1-/-) in a high percentage of the Eurasian populations. Numerous studies have examined the association of GSTM1-/- with breast cancer yielding inconsistent results. In addition, few genetic variants in this gene have been explored. We set out to systematically evaluate the contributions of GSTM1 gene deletion/presence and common variants in GSTM1 to breast cancer, followed by functional studies.
 [Methods and Results] In the present study, we show that GSTM1-/- does confer a weak increased risk of breast cancer compared with GSTM1-present genotype, being confirmed by a meta-analysis of combining 40 related studies with the current case-control study (921 cases vs. 711 controls) of Chinese population (overall odds ratio of 1.10, 95% confidence interval: 1.04-1.15, P<0.001). Unexpectedly, GSTM1 homozygous wild-type (+/+) is also associated with a risk of breast cancer compared with heterozygous (+/-) individuals on the basis of accurate classification using long-PCR-based assay. Furthermore, for the population with one allele of GSTM1 (GSTM1+/-) accounting for 30-50%, we genotype four common single nucleotide polymorphisms (SNPs) spanning GSTM1 gene and identify a functional variant g.-498C>G in the putative promoter region associated with breast cancer risk. It displays that minor -498G allele is significantly more frequent in breast cancer controls than in cases (odds ratio of 0.51, 95% confidence interval: 0.30-0.86, P=0.012). This allele also leads to significantly reduced promoter activity compared to the major -498C allele. Further studies reveal the -498G can modify AP-2 binding site and decrease GSTM1 transcription. Among the three AP-2 isoforms, AP-2α provides the predominant regulation effect on this SNP.
 [Conclusions] These results indicate that the effect of GSTM1 genotypes conferring to breast cancer susceptibility is not dosage-dependent as taken for grant previously. GSTM1 has a two-sided role in breast cancer susceptibility; too high or too low expression of GSTM1 is not beneficial. We recommend that the complicated genetic predisposition of GSTM1 be considered when predicting breast cancer susceptibility using single or a panel of genetic variants.

Abstract #2080
Objective Our study aims to analyze the breast caner patients with different sites of recurrence, and to have knowledge of the regular patterns and influence factors of metastastic breast cancer.
 Methods We performed a retrospective study of 210 female breast cancer patients who were continuously followed up in our hospital from January 2005 to May 2007 and had complete data of metastasis. The clinical and biological characteristics were compared between the patients with organ metastases (lung, liver, brain) and non-viscera metastases (lymph node, bone).
 Results Cox regression analysis-hazard function showed that patients with elder age (RR=0.927 95%CI 0.877∼0.981, P=0.008) and HER-2 negative(RR=0.253 95%CI 0.076∼0.836, P=0.024)tended to develop non-viscera metastases, while patients with larger tumors (RR=3.832 95%CI 1.073∼13.687, P=0.039) tended to develop organ metastasesp.
 
 When stratified by the prognostic factors, the annual risk hazard curve of the patients with high risk of recurrence had double peaks at the second year and the ninth years after mastectomy respectively, and it was significantly higher than those of the patients with middle and low risk.[figure1]Annual risk hazard curves of both local relapse and metastasis also showed a double-peaked pattern. The curves for lymph node, bone, lung and liver metastasis showed a similar pattern, but all the peaks of curve emerged later than that of the local relapse.
 
 Conclusion Patients with different clinical and biological characteristics may develop recurrence in different sites. There are certain regular patterns of time distribution for different metastasis sites after mastectomy. The local recurrence may be the foreboding for the metastasis and we should pay attention to the local relapse signs especially in the patients with high risk.

Abstract
AIMS Our goal was to find a novel, biosurfactant-producing bacterium from Pacific Ocean deep-sea sediments. METHODS AND RESULTS An oil-degrading biosurfactant-producing bacterium TW53 was obtained from deep-sea sediment, and was identified through 16S rDNA analysis as belonging to the genus Rhodococcus. It lowered the surface tension of its culture to 34.4 mN m(-1). Thin layer chromatography (TLC) showed that the crude biosurfactants of TW53 were composed of lipopeptides and free fatty acids (FA). The lipopeptides were purified with column chromatography and then hydrolysed with 6 mol l(-1) HCl. Gas chromatography-mass spectrometry analysis showed that the hydrolyte in the hydrophobic fraction contained five kinds of FA with chain lengths of C(14)-C(19), and C(16)H(32)O(2) was a major component making up 59.18% of the total. However, 3-hydroxyl FA was not found, although it is usually found in lipopeptides. Silica gel TLC revealed that the hydrolyte in the hydrophilic fraction was composed of five kinds of amino acids; consistently, ESI-Q-TOF-MS analysis confirmed the composition results and provided their sequence tentatively as Ala-Ile-Asp-Met-Pro. Furthermore, the yield and CMC (critical micelle concentrations) of purified lipopeptides were examined. The purified product reduced the surface tension of water to 30.7 mN m(-1) with a CMC value of 23.7 mg l(-1). These results suggest that Rhodococcus sp. TW53 produces a novel lipopeptide that we have named rhodofactin. CONCLUSION The deep-sea isolate Rhodococcus sp. TW53 was the first reported lipopeptide-producing bacterium of this genus. The lipopeptides had novel chemical compositions. SIGNIFICANCE AND IMPACT OF THE STUDY Rhodococcus sp. TW53 has potential in the exploration of new biosurfactants and could be used in bioremediation of marine oil pollution.
