Body compositional changes in cancer patients.
Noninvasive and spectroscopic techniques already available and under further development in several laboratories will in the near future give us a greater amount of detailed information on changes in body compartments in disease and in response to therapeutic efforts. Such techniques should have the ability to measure directly components in an organ or tissue in contrast to most present and previous techniques that generally rely on derivation of components from a few direct measurements. Such derivations are unfortunately dependent on assumptions that are not possible to control in several circumstances.
