Abstract:

Objective

To investigate the impact of HMGB1 expression and Bcl-2 expression on chemo-resistance and prognosis of colorectal cancer (CRC).

Method

HMGB1 expression and Bcl-2 expression in CRC tumor tissues from 97 patients was analyzed by immunohistochemistry. Relationship among HMGB1 high expression, Bcl-2 positive expression, clinical histological features, overall survival and chemotherapy response rate were compared.

Results

HMGB1 high expression rates and Bcl-2 positive expression rates in low differentiated and differentiation CRC specimens were significant higher than that in high differentiated tissues (P<0.05). Lymphatic invasion, venous invasion and chemotherapy response rate showed significant correlation with HMGB1 expression (P<0.05). Chemotherapy response rate was also significantly affected by Bcl-2 expression (P<0.05).

Conclusions

HMGB1 high expression and Bcl-2 positive expression may be used to predict chemo-resistance. HMGB1 high expression may be used as predictors of CRC prognosis.
