ObjectiveTo investigate the expression and distribution of CD15s antigen in breast cancer and its relationship with carcinogenesis, progression and metastatic proclivity. MethodsCatalyzed signal amplification(CSA) immunohistochemical technique was used to detect the expression of CD15s antigen in breast cancer and in adjacent normal mucosa. Immunoelectromicroscopic ultrastructural localization of CD15s antigen labelled by colloidal gold was also bserved.ResultsThe positive rate of CD15s antigen expression in primary breast cancer was 79.8%(75/94). In adjacent normal mucosa (n=10) CD15s antigen showed weaker staining. The positive rate of CD15s antigen expression in grade Ⅱ-Ⅲ (87.3%) was notably higher than that in grade Ⅰ (69.2%, P＜0.05). In patients with lymph node metastasis, the positive rate of CD15s antigen expression was 90.2%, which was significantly higher than 67.4% in nodes with no metastasis (P＜0.05). CD15s antigen immunoreactivity was mainly localized in the border membrane of cytoplasm, endoplasmic reticulum, golgi complex and surrounding nuclear membrane in tumor tissue, and in the border membrane of cytoplasm in adjacent normal tissue. Conclusion CD15s antigen is a practical parameter for evaluating the degree of malignancy and lymphatic metastatic proclivity of breast cancer. It can provide a new pathway to investigate the carcinogenesis and progression of breast cancer.

Methods The clinical data of 50 patients with breast tumours with nipple discharge diagnosed in our department form January 2005 to July 2009 were analyzed retrospectively. All patients were proved by molybdenum target mammography, selective mammary ductography and pathology. Results Seventeen patients with breast cancer’s galactographic features were mostly irregular intraductal defect with ductal wall breakage and ductal obstruction in the peripheral ducts; 33 patients with intraductal papilloma’s galactographic features were smooth intraductal filling defect with ductal wall integrity and ductal dilatation and torsion in the main ducts. Conclusions Selective mammary ductography is useful in diagnosis and differentiation of the breast tumours with nipple discharge.

目的 探讨乳腺叶状囊肉瘤和巨纤维腺瘤的诊断和治疗。方法 回顾分析我院1985～2002年期间外科收治的9例乳腺叶状囊肉瘤和8例乳腺巨纤维腺瘤的临床资料。结果 9例乳腺叶状囊肉瘤中行单纯乳房切除术4例，保留乳头皮下乳房切除术1例，保留乳头和部分压缩腺体＋肿块切除术1例，改良根治术3例; 术后恢复良好，仅1例复发。8例乳腺巨纤维腺瘤中行单纯乳房切除术2例，保留乳头皮下乳房切除术1例，保留乳头和部分压缩腺体＋肿块切除术2例，单纯乳腺肿块切除术3例； 术后恢复良好，术后2例复发。结论 乳腺叶状囊肉瘤和巨纤维腺瘤临床上均表现为无痛性包块，除乳腺叶状囊肉瘤发病年龄较大、肿块范围大及易恶变外，二者主要依据病理检查结果相鉴别； 均以手术治疗为主，根据患者年龄、肿块大小以及病理检查结果选择不同的手术方式。
Objective To investigate the role of β-catenin gene in breast tumorigenesis by detecting mutation and expression of β-catenin gene in breast hyperplasia and breast cancer. Methods Mutation and expression of β-catenin gene in 42 breast cancer, 15 simple hyperplasia and 15 atypical hyperplasia were detected by polymerase chain reaction-single strand conformation polymorphism and immunohistochemistry. Results Normal expression of β-catenin occurred in tissue of breast simple hyperplasia. The rate of abnormal expression of β-catenin in tissue of breast atypical hyperplasia and breast cancer were 26.7% （4/15） and 59.5% （25/42）, respectively, which were higher than that of simple hyherplasia tissue (P＜0.05). And there was a markedly difference between the atypical hyperplasia tissue and breast cancer tissue (P＜0.05). Mutation of β-catenin gene wasn’t detected in this three kinds of tissues. Conclusion Abnormal expression of β-catenin plays an important role in human breast tumorigenesis, reason of abnormal expression of β-catenin isn’t mutation of β-catenin gene. Expression of β-catenin can be regulated by other mechanisms.
Objective To determine the investigation progression on exemestane in the treatment of breast cancer. Methods The literatures of recent years on the studies of exemestane were reviewed. Results Exemestane is an effective steroidal aromatase inactivator with superior tolerability, safety and efficacy in the adjuvant, neo-adjuvant and metastatic therapy of breast cancer. Conclusion With the progression of clinical trial with exmestane, exemestane will be regarded as an important drug in comprehensive therapy of breast cancer.
【Abstract】ObjectiveTo observe the effect of nimesulide (NIM) on DMBA-induced mammary tumors and to investigate possible mechanisms of inhibiting tumors. MethodsThe Wistar rats were randomly divided into four groups: DMBA group, NIM+DMBA group, NIM+diet group and diet group. The incidence and mean latent phase of mammary tumors were observed. The number and volume of tumors in every rat were measured. The apoptosis index and proliferation index were evaluated by TUNEL assay and PCNA immunohistochemical staining respectively.Results The latent phases of mammary tumors in NIM+DMBA group were strikingly longer than those in DBMA group 〔(115±14.8) d vs (84±15.6) d,P＜0.01〕. The incidence of mammary tumors was 69.2% in DMBA group, 46.4% in NIM+DMBA group. There was obviously decreased incidence in NIM+DMBA group (P＜0.05）. The number and the mean volume of mammary tumors in every rat in NIM+DMBA group were markedly less than DBMA group 〔（0.82±0.31） vs （1.52±0.43），（3.24±1.21） cm3 vs （6.03±1.84） cm3，P＜0.05〕. The apoptosis index was obviously higher and the proliferation index was markedly lower in NIM+DMBA group compared with DMBA group〔(42.54±13.24)% vs (18.14±6.66)%, (20.25±4.97)% vs (36.36±5.02)%, P＜0.05〕. ConclusionNIM can inhibit the development of DMBA-induced mammary tumors by inhibiting proliferation and inducing apoptosis.
