Abstract: With the advent of the times of immunotherapy and the emergence of a variety of unconventional response patterns such as delayed response and pseudoprogressive disease, a variety of immunerelated efficacy evaluation criteria such as immunerelated response criteria, immunerelated response evaluation criteria in solid tumor and immune response evaluation criteria in solid tumor have been proposed successively. The evaluation principles and judgment results of these criteria are distinctly different from the traditional response evaluation criteria. In particular, the newly proposed immune response evaluation criteria in solid tumor introduces two new concepts of unconfirmed progressive disease and confirmed progressive disease and provides a new response evaluation model for solid tumors, which is expected to provide solutions to some of the most urgent clinical problems under the times of cancer immunotherapy.

Key words: Neoplasms, Immunotherapy, Response evaluation, Immune response evaluation criteria in solid tumors
