Volumetric Analysis in the Assessment of Therapy Response by CT

Inclusion Criteria: * Registered and being treated on one of the following therapeutic protocols: 06-043, 07-052, 07-057, 07-112, 07-116, 08-093, and 08-054 * Have at least one measurable lesion\* as per RECIST criteria situated in lung, liver or lymph node meeting RECIST criteria noted on a baseline CT scan. * Baseline\*\* and at least one follow-up CT scan to likely to be obtained at an MSKCC facility * All patients must be \> or = to 18 years old * The measurable lesions are metastatic in the liver, lung and lymph nodes. The algorithms do not distinguish between primary and metastatic disease, therefore, in selected cases, a primary lesion such as in the liver or lung may also be assessed. * Baseline CT are prefer but if not able to obtain for volumetric reconstructions follow up studies will still be use for other objectives if the study. Exclusion Criteria: * Pregnant or lactating women
