Response to therapy is usually measured using the RECIST criteria [59, 60] for morphologic images (MRI, CT, ultrasound). Tumor sizes, however, do not necessarily reflect the number of viable tumor cells. From other types of oncologic therapy (e.g. chemotherapy) it is known that, in the early post-treatment period, the size of the tumor lesions remains constant even though the number of vi-... [Pg.79]

Table9.1. RECIST criteria offer a simplified, conservative, extraction of imaging data for wide application in clinical trials. They presume that linear measures are an adequate substitute for 2D methods and register four response categories... Table9.1.

Traditional methods for the evaluation of tumor response to therapy have been size reduction on CT through the application of the WHO or Response Evaluation Criteria in Solid Tumors (RECIST) criteria [73, 74]. However, some pitfalls may occur when those methods based on CT dimensional changes are applied to Y therapy. First, RECIST or WHO criteria do not allow for the use of PET scanning in the follow-up evaluation, thereby ignoring the functional nature of the residual tissue. Further-... [Pg.152]

New forms of chemotherapeutic treatment may result in dramatic reduction and advanced necrosis of the lesions on subsequent follow-up CT. Tumour size, as judged by Response Evaluation Criteria of Solid Tumors (RECIST) criteria, may not adequately define response to therapy when the predominant... [Pg.122]
