1. Abstract Bladder cancer is a common malignant disease of the urogenital tract, and over the past few decades, immunotherapy, based on the principle of activating the patient’s immune system to root out malignant cells, has largely changed the treatment of cancer. Anti-PD-1 drugs include monoclonal antibodies against PD-1 and the PD-1 ligand (PD-L1).

1. Abstract 1.1. Background: Convalescent plasma (CP) was demonstrated promising benefit for clinical practice involved in efficacy and safety in previous coronavirus pandemics, however, the efficacy of CP from COVID-19 sufferers are still controversial and unascertainable based on current randomized controlled trials (RCTs). The urgent needs for affirmative replies on the efficacy and safety of CP for COVID-19 patients must be developed as soon as possible.

1. Summary Ovarian tumors occur in one third of all women gynecology organs. Out of that borderline ovarian tumors occur in 10 – 15% out of all ovarian tumors.
