Study summary

This study intends to explore whether the combination of Clostridium butyricum can improve the current situation of poor anti-PD1 treatment effect in patients with bladder cancer.

Read the detailed description

This study intends to explore whether the combination of Clostridium butyricum can improve the current situation of poor anti-PD1 treatment effect in patients with bladder cancer.

This study is divided into two parts. One is the patients with neoadjuvant therapy. After 3 cycles of neoadjuvant therapy, to observe whether the patients with Clostridium butyricum live tablets have better neoadjuvant therapy efficacy. The other was in patients with adjuvant therapy to see if adjuvant therapy combined with Clostridium butyricum could prolong the patient's prognosis.
