The patients must Diagnosis of HER2 breast cancer before surgery
Breast cancer patients need to do HER2 testing, diagnosis of cancer was negative or positive. In breast cancer patient, her2 masculine breast cancer patient’s worsened speed often is higher than the negative patient. If you do not do that and blind to take surgery. missed the best time for treatment, some diseases are accumulated by the medicine surface alleviation function cover Cheng Dabing.
HER2 is a protein, belongs to the Epidermal Growth Factor receptor family, is one of The most vμlnerable oncogene in human tumor. It is a protein produced by a specific gene with cancer-causing potential. The positive expression rate of HER2 was 54.54%(60/110). the number of HER2 protein which Surface of tumor cells is increased. In HER2-positive breast cancer, increased quantities of the HER2 protein are present on the surface of the tumour cells. Research shows that HER2-positivity affects approximately 20-30% of women with breast cancer. Around 15 – 25% of women with early breast cancer hae a type called HER2-receptor positive disease. The overexpression of HER2 on the endocrine therapy often precedes is not sensitive to rapid tumor progression, prone to lymph node or hematogenous metastasis, the prognosis is not so good. Breast carcinoma patients with positive expression of HER2 had higher metastatic rate(P<0.01) and poorer survival rate in 5 years(P<0.01).
HER2-positive breast cancer survival time was 1 to 3 years, and HER2-negative patients survived at least 4 to 6 years. if check the status of HER2 in time and use the right treatment, Chances of survival of HER2-positive patients with breast cancer will be close to normal. If determined that her2 is a masculine gender, should in view of her2 gene marching song proper bead Shan Kangba to the treatment, reduce the recrudescence risk promptly. A number of large-scale clinical trials have shown that Targeted therapy can make the HER2-positive early breast cancer reduces the risk of tumor recurrence 52%.33% lower risk of death.
