Target Tumors: A Case Study

Decent Essays

RECIST 1.0 was introduced in 2000 as a standardised method to evaluate response to treatment with chemotherapeutic agents(Patrick Therasse, Richard S. Kaplan et al. 2000). This has been further updated in 2009 (Eisenhauer, Therasse et al. 2009). Treatment response defined by RECIST depends solely on size change of the target tumours. It looks at the change in size of the sum of uni-dimensional measurements of tumour target lesions performed with a specific imaging modality. The tumours are classified as measurable lesions (target lesions) and non-measurable (non-target lesions). The lesions that measure more that 2.0cm by non-helical CT methods and 1.0cm by helical CT and which can be measured accurately repeatedly are considered as measurable
