Response rate (RR)Response rate measures disease size, usually using a scan or X-ray. Complete response (CR) Disappearance of all clinical evidence of disease.

A partial response is a decrease in the size of a tumor or in the amount of cancer in the body, and a complete response is the disappearance of all signs of cancer in the body.

What is the objective response rate in oncology?
The tumor objective response rate (ORR) is an important parameter to demonstrate the efficacy of a treatment in oncology. The ORR is valuable for clinical decision making in routine practice and a significant end-point for reporting the results of clinical trials.
What is the objective response rate ( ORR )?
The tumor objective response rate (ORR) is the assessment of the tumor burden (TB) after a given treatment in patients with solid tumors and has a long history. The ORR is undoubtedly an important parameter to demonstrate the efficacy of a treatment and it serves as a primary or secondary end-point in clinical trials.
Which is the best Bor for objective response?
