A 71-year-old patient with high-grade non-Hodgkin's lymphoma stage IVB, severe lactic acidosis and tumor-associated hypoglycemia is described. Endocrine causes of hypoglycemic episodes were excluded because of low serum concentrations of insulin and "insulin-like growth factor 1", and normal concentrations of growth hormone and thyroid hormone. Clinical conditions associated with lactic acidosis such as diabetes mellitus, biguanide intoxication, septicemia, acute hypoxemia, or circulatory insufficiency were ruled out. Enhanced glucose metabolism within the tumor was visualized by positron emission tomography employing 2-fluro-2-deoxy-D-glucose (FDG) as a tracer. A markedly elevated tumor necrosis factor-alpha (TNF-alpha) level was found which decreased after cytoreductive therapy paralleling the normalization of serum lactate. In contrast to the majority of cases of lymphoma-associated lactic acidoses reviewed to date, in our case lactate elimination was not reduced.

The aim of this study was to evaluate the growth and growth hormone (GH) secretion, as assessed by the rate and pattern of secretion, in patients in remission from non-Hodgkin's lymphoma (NHL) who had been treated with corticosteroids and intense chemotherapy. None of the patients had received cranial irradiation. Twelve children were investigated yearly by taking 24-hour GH profiles starting 1 year from the time of diagnosis. The mean age at onset of the disease was 7.5 years. Another 12 young adults were studied in a cross-sectional manner 4.1-21.3 years (mean, 9.0 years) after diagnosis of NHL. The mean age at onset of the disease was 10.7 years. The median height velocity was significantly decreased during the 1st year following diagnosis (standard deviation scores [SDS] -0.15, P < .001), especially during the first 3 months (SDS -0.75, P < .001) when the most intense treatment was given. During the 2nd year height velocity was still somewhat reduced (SDS -0.13, P < .001). However, there was no reduction in final attained height. Spontaneous GH secretion, in terms of both secretory rate and pulsatile pattern, was evaluated by measuring integrated GH concentrations in 20-minute blood samples collected over a 24-hour period. The plasma GH concentrations were transformed into GH secretion rates by means of a deconvolution technique. Fourier time series analysis was applied to determine possible disturbances of rhythmicity of the GH secretion. The GH secretion rate and the pulsatile pattern of secretion in the NHL patients were similar to those of the reference population of pubertal matched healthy controls. There was no influence of the age at diagnosis or of the time from diagnosis of NHL on the GH secretion rate. Growth impairment in children with a malignant disease treated only with steroids and chemotherapy is therefore probably not caused by disturbed GH secretion, but rather by direct interference with bone growth of the cytotoxic drugs used. There was no significant influence on weight gain during the treatment period so an indirect effect of chemotherapy on bone growth through interference with adequate nutrition seems unlikely. However, GH secretion was not evaluated during the period of growth retardation, and therefore a transient deficiency was not excluded.

The effects of growth hormone are mediated in part by stimulating the production of insulin-like growth factor-1. Insulin-like growth factor-1 has significant effects on cell proliferation and differentiation, it is a potent mitogen, and it is a powerful inhibitor of programmed cell death (apoptosis). Insulin-like growth factor-1 also has a well-established role in the transformation of normal cells to malignant cells. Case reports on a possible association between elevated growth hormone and cancer risk in a variety of patient groups have been published. Here, we describe clinical and laboratory findings for a patient with acromegaly who first developed thyroid cancer, and then, in the follow up period, probably due to poorly controlled insulin-like growth factor-1 levels, developed a large cell non-Hodgkin's lymphoma. A search revealed that a case with these peculiarities had not previously been reported.
