Objective: The morbility of male breast cancer is lower than female breast cancer.The treatment effectiveness of male breast cancer is worse than female breast cancer.There were fewer studies on male breast cancer.The aim of the paper was to study the clinical characteristics,diagnosis,treatment and the prognostic factors of male breast cancer.Methods: To analyze the clinical data of 2 cases of male breast cancer and 409 cases collected from past articles retrospectively.Results: All cases received surgery treatment.After operation,all cases were treated by adjuvant treatment including radiotherapy or/and chemotherapy or/and endocrine treatment.The major pathological type was infiltrative non-specific cancer.Estrogen receptor and progesterone receptor are positive in most cases.Cases in stage Ⅰ were fewer,more cases were in stageⅡor stage Ⅲ and stage Ⅳ.Prognosis are more better in stage Ⅰ patients than in stageⅡ、Ⅲ、Ⅳ patients.Conclusion: Male breast cancer has the following clinical characteristics: lower incidence,older age,longer course,higher malignancy and poor prognosis.The operation combined with radiotherapy and chemotherapy and endocrine treatment was a better method to treat male breast cancer.

Objective: To observe the role of nutritional support in treatment of chylous leakage after thyroid carcinoma operation.Methods: The parenteral nutrition combined with somatostatin and re-operation was used in treatment of 2 cases of chylous leakage after thyroid carcinoma operation.Fluid volume from neck drainage catheter and plasma albumin concentration were determined in 2 cases.Results: Fluid volume from neck drainage catheter rapidly reduced in 2 cases after using somatostatin and parenteral nutrition.1case was cured after conservative treatment.1 case was cured after re-operation combined with nutrition support.Conclusion: By using nutrition support,fluid volume from neck drainage catheter can be obviously reduced and serum albumin or nutritional state improved in chylous leakage patients after thyroid carcinoma operation.

Objective:To explore the clinical diagnosis,therapy and pathologic characteristics of primary bilateral breast cancer in order to improve the survival of breast cancer patients.Methods:Eleven cases of primary bilateral breast cancer patients were retrospective analysised.Results:Among the 11 cases of primary bilateral breast cancer patients,2 cases were dead for multi organ metastasis;9 cases survived.Among which one has been alive for 6 years after operation.Conclusion:The early diagnosis and treatment of the second primary cancer remain the key factor to improve the outcome of the bilateral breast cancer patients.

The incidence of breast cancer has markedly increased in recent years.Breast cancer has become a major cause of death of adult females.Many studies have shown that glucose metabolism disorders and its connected factors have been closely related to occurrence and development of breast cancer.Regulation of glucose metabolism and related factors may become an important way in prevention and treatment of breast cancer.

[Objective] To explore the clinical effect of Buyang Huangwu Decoction and Guipi Decoction together on BTS. [Method] Select 48 cases of BTS in accordance of diagnosis standard, divide them into treatment group 48 cases(take revised Buyang Huangwu Decoction and Guipi Decoction ) and control one 20(routine western medicine), judge their cure effect after 2~4 courses. [Result] The cure rate and total effective rate were respectively 60.42%and 87.50% for treament group, for control one, they were respectively 30.00% and 65.00%; with χ2 test, their differences were respectively of marked statistical meaning and statistical meaning. [Conclusion] Buyang Huangwu Decoction and Guipi Decoction together had definite cure effect on BTS.

Objective:To explore the clinic and pathologic characteristics of primary breast lymphoma(PBL) for its diagnosis and treatment.Methods: Five cases of PBL that has been diagnosed during 1998-2005 were analyzed.Results: One patient died 1 month after her final diagnosis.Tow patients have survived 4 and 3 years,respectively,after radical operation plus chemotherapy,although inguinal lymphatic metastasis was found in the later one 2 years after her operation.Another two patients have been accepting chemotherapy for 3 months after their local resection.Conclusion: PBL is diagnosed basically by methods of pathology and immunohistochemistry,and treated mainly by chemotherapy combining with other therapies.

Objective: Breast conserving surgery has been proved to be a safe strategy and widely applied to the treatment of early breast cancer.The aim of this work is to evaluate the operational techniques and effect of conservative surgery for breast cancer.Methods: We analyzed the clinical data of 20 patients with breast cancer that underwent conservative surgery from January 2004 to December 2007.All the tumors were found to be solitary,less than 3 cm in diameter,and treated by postoperative chemotherapy and radiotherapy.All the patients were followed for 5 to 52(mean 28) months.Results: During the follow-up,2 cases experienced local recurrence and received modified radical mastectomy.All the 20 patients remained alive up to the present study.Conclusion: The principle of specific procedures for specific cases counts quite a lot for satisfactory prognosis and outcomes of breast conservative surgery.

Triple-negative breast cancer (TNBC) is a subgroup of breast cancers defined by a lack of the expressions of estrogen,progesterone and HER2 receptors,with more aggressive biological and clinicopathological characteristics and a close relationship with basal-like and breast cancer susceptibility gene-1 (BRCA1)-related breast cancers.TNBC is insensitive to most available hormonal or standard therapeutic agents,associated with increased risk for distant metastases and with poorer prognosis than other types of breast cancer.A deeper insight into the biology of TNBC may lead to improved therapies and better clinical outcomes of the disease.

Objectives:To investigate the association and the prognostic significance of the expression of telomerase activity (TA) and apoptosis (APO) in tissues of primary breast cancer.Methods:TRAP-PCR and ELISA were developed to detect the expression of TA,and make quantitative and qualitative analysis respectively.TUNEL was also used to evaluate apoptosis cells in cancer lesions and count apoptosis index (AI).The expression levels of proteins of oncogene Bcl-2 and p53 were measured by means of S-P immunohistochemistry.Results:The mean TA positive expression rate was 89.8%,and its mean optic density was (A) 0.63±0.29,which were significantly higher than those of normal tissues and benign breast lesions (P<0.05).The 5 years survival rate of patients with positive TA expression was lower (60.3%) than those of negative expression (77.4%).There were no relations between TA expression and patients ages,TNM staging,lymph nodes metastasis,size,locations and pathological types of cancer.But TA was positively correlated with APO (r=0.733 1,P<0.05) and the protein expression of oncogene Bcl-2 (r=0.781 4,P<0.05) and negatively correlated with that of p53 (r=-0.625 5,P<0.05).Moreover,in patients receiving preoperative chemotherapy,the levels of TA expression were much lower than those without chemotherapy (64.7% vs 85.1%),and the former had higher AI than the latter (7.19±3.75% vs 3.23±2.04%),intraarterial chemotherapy group were superior significantly to adjuvant group (P<0.05).Multivariate Cox Regression Analysis showed that only TA and AI influenced the survival time of primary breast cancer patients,and patients with higher positive TA expression and AI>4.0% had shorter survival time than those of negative TA expression and AI<4.0% patients.Conclusions:There was a significant correlation between TA and APO and its related oncogene Bcl-2,p53.TA and APO are of great diagnostic values,therapeutic helps and prognostic significance in the formation and the development of primary breast cancer.

Objectives：To investigate the pathological and clinical effect of preoperative arterial infusion chemotherapy on breast cancers.Methods:Twenty patients with breast carcinoma received regional arterial angiography by Seldinger's procedure followed by arterial infusion chemotherapy.Sixteen patients who didn't undergo preoperative chemotherapy were selected as controls.All the operation specimens were analyzed by the same pathologist.Results:Histological analysis of the two groups revealed the following results:① cancer tissue necrosis increased in the arterial chemotherapy group;②karyopyknosis,karyorrhexis coagulation and necrosis of cytoplasm around the vascular vessels as well as interstitial edema were found in the tumor tissue,invasion of inflammatory cells,intimal proliferation thrombus and inflammation of vessels could also be seen.All the changes were much severe in the infusion chemotherapy group than in the controlled group;Conclusions:Histological changes are significant after preoperative arterial infusion chemotherapy for breast carcinoma.
