Objective To explore the clinical characteristics,pathology,prognosis and proper treatment of tubular carcinoma of the breast. Methods The clinical data of 11 patients with tubular carcinoma of the breast treated in Peking Union Medical College Hospital were retrospectively analyzed.Results The incidence of tubular carcinoma of the breast account for 0.4% of the total breast cancer cases.Eight out of 11 cases had palpable painless lumps in the breast.Six cases received modified radical mastectomy,among which one patient received modified radical mastectomy of both sides.Four patients underwent breast conservation therapy.Sentinel lymph nodes biopsy was conducted in 2 patients.By immunohistochemistry ER was positive in 6 cases,PR was positive in 7 cases,2 cases were axiilary lymph node positive.Three patients received chemotherapy.Two patients received endocrine therapy(tamoxifen or aromatase inhibitor).Other patients received combined therapy including radiation,endocrine therapy and chemotherapy.All the patients have been followed up from 1 month to 7 years and within the period there is no recurrence,metastasis and death. Conclusion Tubulax carcinoma of the breast is a kind of low malignant tumor.Proper surgery and adjuvant therapy is important to improve survival and the quality of life.

Objective To explore whether dithiothreitol(DTT)is helpful for PreScission Protease to cut off the GST from GST?CT3 protein. Meth?ods The pGEX?6P?3/CT3 recombinant plasmid was transfected into Escherichia coli BL21,and the GST?CT3 fusion protein was purified by B?PER method. PreScission Protease was applied with 10 mmol/L DTT to cut off the GST,then the SDS?PAGE was performed for identification of the CT3 protein. Results Without DTT,it was very difficult for PreScission Protease to cut off the GST from GST?CT3 protein. However,in the pres?ence of 10 mmol/L DTT,PreScission Protease could cut off the GST easily as identified by SDS?PAGE. Conclusion 10 mmol/L DTT can help Pre?Scission Protease to cut GST from GST?CT3 protein,so as to achieve high concentration of CT3.

OBJECTIVETo investigate the effects of different concentrations of lipopolysaccharide (LPS), tumor necrosis factor α (TNFα), interleukin-6 (IL-6), dexamethasone (Dex), and insulin on the mRNA and protein expressions of GPR54 in the MCF7 cell line in vitro.

METHODSMCF7 breasr cancer cells were cultured and treated with different concentrations of LPS (10 and 20 µg/ml), TNFα (20 and 100 ng/ml), IL-6 (10 and 20 ng/ml), Dex (10(-6) and 10(-7) mol/L), and insulin (0.01 and 0.1 IU/L). Those treated with culture fluid only served as controls. The mRNA and protein expressions of GPR54 were measured by real-time PCR and Western blot, respectively, after 6, 24, 48, and 72 hours of treatment.

RESULTSCompared with the blank con- trol, LPS (10 and 20 µg/ml), TNFα (20 and 100 ng/ml), IL-6 (10 and 20 ng/ml), Dex (10(-6) and 10(-7) mol/L), and insulin (0.01 and 0.1 IU/L) significantly increased the expressions of GPR54 mRNA (P < 0.05) and protein (P < 0.05).

CONCLUSIONLPS, TNFα, IL-6, Dex, and insulin evidently increase the expression of GPR54 in the MCF7 cell line, indicating their influence on the function of gonads by regulating the GPR54 level.

Objective To evaluate the value of quantitative 3T dynamic contrast enhanced MRI in the diagnosis of breast lesions. Methods One-hundred and eighteen patients suspected of breast lesions underwent MRI examination. A 3.0 T MR scanner was used to obtain the quantitative MR pharmacokinetic parameters: Ktrans( volume transfer constant), Kep (exchange rate constant) and Ve (extravascular extracellular volume fraction). The mean Ktrans, Kep and Ve of malignant, benign and normal glandular tissues were calculated and compared each other using LSD method. Independent sample t test was used between invasive ductal carcinoma and ductal carcinoma in situ (microinvasion included). Finally, the areas under the ROC curve (AUC) of Ktrans, Kep and Ve between malignant and benign lesions were compared. Results The mean Ktrans, Kep and Ve of malignant lesions (n=87) were (1.010±0.580) min-1, (1.634 ± 1.481) min-1 and (0.735 ±0.273); the mean Ktrans, Kep and Ve of benign lesions (n=23) were (0.331±0.192) min - 1, (0.417±0.324) min - 1 and (0.847±0.291); and the mean Ktrans, Kep and Ve of normal glandular tissues (n =83) were (0.051 ±0.028) min-1, (0.133±0.125) min-1 and (0.597±0.354), respectively. There were significant differences between normal glandular tissues and benign lesions, normal glandular tissues and malignant lesions, benign and malignant lesions in Ktrans (t=9.681, 11.189, 5. 590, respectively, P ＜ 0. 01 ), normal glandular tissues and malignant lesions, benign and malignant lesions in Kep(t =5. 287, 3. 874, P＜0. 05). There were a statistic differences between normal glandular tissues and benign lesions, normal glandular tissues and malignant lesions in Ve(t =2. 932, 2. 562 ,P ＜0. 05). There were no significant differences between normal glandular tissues and benign lesions in Kep, benign and malignant lesions in Ve ( t = 0. 760, 0. 832, P ＞ 0.05 ),invasive ductal carcinoma and ductal carcinoma in situ (microinvasion included) in Ktrans, Kep and Ve(t =0.834,0.075,0.454,P＞0.05). The areas under the ROC curve (AUC) of Ktrans, Kep and Ve between malignant and benign lesions were 0. 934, 0. 941 and 0. 659. The sensitivity of Ktrans, Kep and Ve were 77.01% ,91.95% ,56. 32% and the specificity of Ktrans, Kep and Ve were 95. 65%, 86. 96%, 78.26% for the differential diagnosis of breast lesions if taken the maximum Youden's index as cut-off. Conclusion The differential diagnosis of benign and malignant breast lesions by Ktrans, Kep is applicable.

Objective To explore the association of estrogen receptor β expression with different stages and molecular subtypes of invasive breast cancer.Methods The clinicopathologic data of 446 invasive breast cancer cases was retrospectively analyzed.ERβ expression was evaluated by types and stages.Results Of all 446 invasive breast cancer cases,328 (73.5％) were ERβ positive.The ERβ positive rate was 77.9％ (240/308) and 63.8％ (88/138) in ERα + group and ERα-group,respectively.The ERβ expression in breast cancer was positively correlated with ERα (P ＜ 0.01) while it had no correlation with PR,histological grade,HER-2 and Ki-67 (P ＞ 0.05).ERβ expression was not significantly different among different age,tumor size and axillary lymph node groups(all P ＞ 0.05).A total of 418 invasive breast cancer cases were recruited for pathologic stage and NPI analysis,including 168 cases at stage Ⅰ,152 cases at stage Ⅱ and 98 cases at stage Ⅲ.ERβ expression was not significantly different among different stages of breast cancer(P =0.743).Analyzed in these 418 cases,NPI was ＜ 3.4 in 126 cases,3.4-5.4 in 207 cases and ＞ 5.4 in 85 cases.ERβ expression was not significantly different among different NPI group (P =0.644).The ERβ positive rate in Luminal A subtype,Luminal B1 subtype,Luminal B2 subtype,HER-2 subtype and TN subtype was 75.6％ (88/118),75.9％ (110/145),85.2％ (46/54),68.4％ (39/57) and 62.5％ (45/72) respectively.ERβ expression was significantly different between Luminal subtype and non-Luminal subtype (P =0.007).Conclusions ERβ was not differentially expressed among different breast cancer stages and NPI groups.ERβ was differentially expressed in different breast cancer molecular subtypes.

Background and purpose: With the development of the means of preoperative diagnosis and treatment of breast cancer, ifne needle puncture no longer seems to be popular with the clinical use. The safety and effectiveness of fine needle aspiration as preoperative diagnosis of breast cancer are controversial. This study was aimed to investigate the application of fine needle aspiration (FNA) of breast cancer and association between FNA and recurrence and metastasis for 30 years in our hospital. Methods:A total number of 1 260 patients with breast cancer treated in Peking Union Medical College Hospital from 1975 to 2006 were reviewed in two groups for clinical characters, recurrence, and survival rate. The two groups were FNA and non-FNA. Results:The positive rate of FNA was 61.4%and the highest rate was inⅣstage (100%). StageⅡandⅢwere the major ones in FNA group (45.2%). The local recurrence (7.0%vs 6.4%), recurrence and metastasis (13.2%vs 14.0%), 5-year (82.0%vs 81.0%) and 10-year disease free survival rates (51.0%vs 64.0%) have no signiifcant difference between FNA and non-FNA groups. Conclusion:FNA is still one of the most important methods for preoperative investigation of breast cancer.

Breast cancer is the leading cause of malignancy-related mortality in women worldwide. The more accurate prediction of lymph node metastasis and evaluation of personalized prognosis of breast cancer patients could provide evidence and reference for individualized comprehensive treatment and clinical decision-making. Nomogram is statistical calculation model developed to generate individualized prediction of a certain clinical event through the factors associated with it. Currently breast cancer related nomogram models is most commonly used in the prediction of non-sentinel lymph node status in patients with sentinel lymph node-positive breast cancer, sentinel lymph node metastasis in clinical node-negative breast cancer and prognosis evaluation of breast cancer. This article reviewed the recent advances in breast cancer related nomograms according to the above mentioned three aspects, and evaluated respectively the predictive factors, accuracy, characteristics and clinical application potential.

Objective:To analyze the distribution, clinico-pathologic features, and survival status of different subtypes in axillary lymph node-negative invasive breast cancer patients. Methods:In this study, data of 183 patients were included and retrospectively ana-lyzed in terms of age distribution, clinico-pathologic features, disease-free survival (DFS), and overall survival based on different sub-types (luminal, basal-like, and HER-2 over-expression). Results:No significant differences in age, tumor size, and TNM stage was ob-served among different subtypes. The relapse rates of luminal, basal-like, and HER-2 over-expression subtypes were 3.9% (4/102), 20.4% (10/49), and 6.3% (2/32), respectively (P=0.002). The death rates of luminal, basal-like, and HER-2 over-expression subtypes were 2.0%(2/102), 6.1%(3/49), and 3.1%(1/32), respectively (P>0.05). Kaplan-Meier analysis showed that the DFS of basal-like sub-type was much lower compared with that of the luminal and HER-2 over-expression subtypes (P=0.002). Cox analysis showed that the subtype was an independent prognostic indicator (P=0.001). Conclusion:In node-negative invasive breast cancer, no significant differ-ences in age distribution, tumor size, and TNM stage was observed among different subtypes. The basal-like subtype has the worst prog-nosis. Therefore, subtype is an important independent prognostic indicator.
