<qa>  What is the most common type of disease that can be assessed by radiographic measurement?8. Patients must have measurable tumor by Response Evaluation Criteria in Solid Tumors RECIST Therasse et al, 2000. Measurable disease includes any lesion 1 cm by spiral CT or 2 cm by non-spiral CT in longest diameter which can be repetitively assessed by radiographic measurement or any lesion 2 cm in longest diameter which can be repetitively assessed by physical examination. Positive bone scans, osteoblastic or osteolytic bone lesions, pleural effusions and positive bone marrow biopsies are not considered acceptable as either measurable or evaluable lesions.
