Abstract: | In 16 patients with metastatic testicular cancer and 10 age matched male control subjects growth hormone (GH) responses to growth hormone releasing hormone (GHRH; 1 microgram/kg body weight iv.) and thyrotropin releasing hormone (TRH; 200 micrograms iv.) were measured. Basal GH levels and GH levels following stimulation with GHRH or TRH were significantly increased in cancer patients compared to control subjects. 9 patients with testicular cancer were studied both in the stage of metastatic disease and after they had reached a complete remission. In complete remission GH responses to GHRH tended to decrease but the differences did not reach statistical significance. Our data suggest an alteration of hypothalamic and/or pituitary regulation of GH secretion in patients with metastatic testicular cancer. |
