- At least one radiographically documented lesion measurable according to response evaluation criteria in solid tumors (RECIST) 1.0. All target lesions are to be measurable (that is, the lesion must be adequately measurable in at least one dimension; longest diameter to be recorded as >= 2 centimeter (cm) by conventional techniques or >= 1 centimeter (cm) by spiral computed tomography [CT] scan). Target lesions are to be selected from the required protocol imaging. If the sole site of measurable disease is in a prior radiation field, there has to be unequivocal evidence of progression at >= 8 weeks since the completion of radiation or a positive biopsy
