Objective: To investigate the expression of metastasis-associated gene 1 (MTA1) and matrix metalloproteinase 9 (MMP-9) gene in breast carcinoma and the relationship between the expression of these genes and the invasion of breast cancer.
Methods: Fluorescence quantitative PCR technique was used to detect the mRNA expression of MTA1 and MMP-9 gene among 56 human breast cancer samples.
Results: The mRNA expression rate of MTA1 was higher in 83.
Objective: To summarize the diagnosis and treatment of breast lumps in children.
Methods: The clinical data of 61 children with breast lumps, 20 with physiological breast masses, 5 male and 15 female, aged 1 - 14, 38 with benign tumors, 1 male and 37 female, aged 10 - 14, 3 with malignant tumors, aged 7 months, and 10 and 13 years. diagnosed and treated 2001 - 2006 were analyzed.
