2.2 The type of results measured
According to Response Evaluation Criteria in Solid Tumors (RECIST), the
objective efficacy evaluation standard for solid tumors, it can be
divided into: complete response (CR): all measurable tumor lesions
disappear completely and maintain for more than 4 weeks; Partial
response (PR): the sum of the products of the largest diameter and the
largest perpendicular diameter of each lesion was reduced by no less
than 50% and maintained for more than 4 weeks without the appearance of
new lesions. Stable disease (SD): 50% decrease or more than 25%
increase in the sum of the products of the largest diameter and the
largest perpendicular diameter of each lesion; Progressive disease (PD):
at least 25% increase in the product of the largest diameter and the
largest perpendicular diameter in at least one lesion or new lesion. ORR
was the primary clinical outcome. CR plus PR were combined into the data
pool as ORR.
