Brief summary

Clinical trial to investigate the relationship between the expression of immunohistochemical biomarkers GATA-3, CK20, P53 and Ki67 in bladder cancer and pathological complete response after neoadjuvant chemotherapy.

Detailed description

This is a retrospective study included bladder cancer patients treated with neoadjuvant chemotherapy. We analyzed the changes in the expression of GATA-3, CK20, P53 and Ki67 before and after NAC. Evaluating the sensitivity factor for predicting pathological complete response.

Interventions

OTHERneoadjuvant chemotherapy

The patients receive neoadjuvant chemotherapy for 2-4 cycles before surgery.
