We have used a sensitive chemiluminescence GH assay to analyse 24-hour GH profiles (20 minute sampling) from 11 adult cancer survivors with severe GH deficiency acquired following brain irradiation in childhood for non-pituitary brain tumours and 30 matched healthy normal volunteers. Cluster analysis revealed that the area under the curve for GH (AUCGH), absolute (maximum) GH peak height, mean peak height, maximum pulse area, mean pulse area, absolute (minimum) nadi...

Tumoural GH secretion in acromegaly is characterised by increased non-pulsatile (basal) release, pulse amplitude and pulse frequency. We have studied the effect of primary therapy with Sandostatin LAR on GH pulsatility in 9 patients with acromegaly who achieved disease control (mean serum GH<2ug/L) on therapy (7 males; median (range) age 67 (43-75). Data obtained were compared with 16 healthy subjects (10 males, age 50 (30-75)). Spontaneous 24-h GH secretion (20 minute samp...
