Objective: To study the expressions and significations of metallothionein (MT) in cervical squamous cell cancer (CSC), bladder transitional cell cancer (BTC) and breast cancer (BC) of woman. Methods: Immunohistochemical method was used to examine the expresses rate of MT in three types of woman cancer tissue. Results: The expressions rates of MT were 54.35% (29146) in BTC, 67.05% (59188) in BC and 57.14% (40/70) in CSC. The positive rate of MT expression was higher in low differentiation group than well differentiation group in BTC and CSC (P 〈 0.05). Positive of MT in lobular cancer was significance higher than medullary and duct cancers (P 〈 0.05). Conclusion: The expression of MT is related to differentiation degree, and it is a guidance for clinical choice of chemotherapy project. 展开更多

Objective: To study the expressions of (CSC), bladder transitional cell cancer metallothionein and the significances in cervical squamous cell cancer (BTC), esophageal squamous cell cancer (ESC), gastral tubular adenocarcinoma (GC) and large intestinal tubular adenocarcinoma (LIC). Methods: lmmunohistochemical method was used to examine the expression rates of MT in five types of cancer tissue. Results: The expression rates of MT were 75.00% (24/32) in ESC, 52.27% (46/88) in GTC, 59.46% (44/74) in LIC, 64.86% (48/74) in BTC and 58.57% (41/70) in CSC respectively. The positive rates of MT expression were higher in low differentiation and deep muscular group than those in medium or high differentiation and superficial muscular invasion group (P〈0.05). Conclusion: The expression of MT is related to differentiation degree and invasion degree. 展开更多
