    Abstract:
    Prostaglandin-E2 (PGE2) and interleukin-1 (IL-1) production from plastic-adherent peripheral blood mononuclear cells stimulated in vitro by bacterial lipopolysaccharide, serum and urinary glucocorticoid levels and the circadian rhythm of serum cortisol levels were studied for better understanding of the immunological and physiological changes produced by systemic chemotherapy in cancer patients. In one responded patient out of four, PGE2 production decreased and IL-1 production increased, whereas the serum cortisol level decreased and the urinary 17-KS excretion level increased. The circadian rhythm of the serum cortisol level was evaluated three times a day, at 7 A.M., 2 P.M. and 10 P.M. Healthy volunteers showed a peak level at 7 A.M. which decreased gradually towards evening and reached to the lowest level at 10 P.M. In contrast, cancer patients showed three additional patterns. These patterns were classified as follows, Type N showed a maximal level at 7 A.M. and minimal level at 10 P.M. as same as in healthy subjects. Type V showed a minimal level at 2 P.M. while type A showed a maximal level at this time. In type F the serum cortisol level was no greater than 1.0 micrograms/dl at any of the three time points. We examined circadian rhythm in four cancer patients treated with systemic chemotherapy. In one PR case, the circadian rhythm shifted from type V to N after the first course of therapy, then changed to type F after subsequent and another courses of the therapy. In another PR case, type N persisted during and after therapy. One MR case shifted from type A to type N. In contrast, one PD case shifted from type N to A. There results suggest that normalization of the circadian rhythm of serum cortisol was associated with the improvement in host body condition achieved by chemotherapy and that systemic chemotherapy modified the immunological and physiological state of cancer patients, as defined above. This may eventually be beneficial for patients.
