Figure 8:

Objective response rate reflects the degree of tumor shrinkage and is defined as the proportion of patients who experience a complete response (CR) or partial response (PR) while receiving treatment. A, A patient who underwent chest CT that revealed a single site of disease at baseline experienced, B, marked decreased size of the right paratracheal lesion, and thus is an objective responder. C, Objective responders are the percentage of patients with CR and PR. Arrow indicates the single site of disease, mediastinal lymphadenopathy. PD = progressive disease, RECIST 1.1 = Response Evaluation Criteria in Solid Tumors version 1.1, SD = stable disease.
