A total of 173 times of adverse reaction occured, of which 20 were ≥ grade 3. Tumor markers in these patients had a downward trend. After neoadjuvant therapy, patlogy complete response happened in 16 cases （22.2%）, partial response in 49 cases （68.1%）, stable disease in 6 cases （8.3%）, progression in 1 cases （1.4%）, the response rate was 89.0%.
