Objective To study the relationship between metalloproteinases (MMPs) and breast cancer. Methods The literature in recent years on the relationship between the expression of MMPs and breast cancer was reviewed. Results The balance between MMPs and tissue inhibitors of metalloproteinases (TIMPs) is keeping normally kept in human body. Many of the studies showed that the expression of MMPs is increased in breast cancer. Conclusion The growth, invasion and metastasis of breast cancer is closely related with the increased expression of MMPs. This suggests that MMPs is a valuable prognostic marker and TIMPs would be a novel drug against cancer.
ObjectiveTo explore the expression of collagen Ⅳ in breast cancer and its clinical significance. We analyzed the correlation of the results with other prognostic parameters which included tumor size, status of estrogen receptor, axillary nodal status, TNM grade, and 5 years survival. The expression of collagen Ⅳ in 93 cases of human primary breast cancer as well as 5 cases of benign breast masses were examined.MethodsUsing monoclonal antibodies of collagen Ⅳ, the expression of collagen Ⅳ in breast masses were detected with immunohistochemical technique (LSAB).ResultsThe absent expression of collagen Ⅳ in the tumor masses was correlated with axillary lymph node involvement, tumor size and poor prognosis (5 years survival). The patients who had no expression of collagen Ⅳ in tumor masses had a shorter survival. ConclusionThe expression of collagen Ⅳ in tumor samples are correlated with axillary node involvement and prognosis. Collagen Ⅳ would be helpful for evaluation of invasion and treatment in breast carcinoma.

ObjectiveTo summarize research progress of comprehensive treatment based on gene therapy, immunotherapy, and targeted therapy in recent years in order to improve understanding and treatment level of triple negative breast cancer (TNBC).MethodThe literatures about TNBC treatment in recent 5 years were reviewed and summarized.ResultsTNBC was more invasive than other types of breast cancer due to its lack of targeted receptors, and its recurrence and metastasis were earlier. The treatment plan was still mainly surgical treatment, supplemented by the chemotherapy and radiotherapy.ConclusionsAlthough recent studies of TNBC in surgical treatment, chemoradiotherapy, targeted therapy and other aspects have shown a good clinical application prospect, more evidences of clinical trials with large samples are still needed. With the deepening of molecular mechanism research, endocrine therapy and targeted drug therapy, including androgen-receptor-positive, have provided some new ideas for treatment of TNBC.
