Background: In childhood, cisplatin is an essential
component of solid tumour therapy such as in neuroblastomas, germ cell
tumours, bone tumours, liver tumours and brain tumours. The potential
nephrotoxicity of cisplatin is widely recognized, but little information is
available on permanent sequelae. Methods: Of the 500
children included in the Swiss Pediatric Oncology Group Late Effect Study,
a group of 46 patients (27 males and 19 females) aged 5.7-28 years (median
14 years) surviving the above-mentioned solid tumours entered the present
study. The patients were disease-free and off antineoplastic medication for
at least 3 years. No recent gastrointestinal or urinary disturbances had
occurred, and diets as well as appetites were normal.
Results: Blood pressure and plasma or urinary calcium
and phosphate were similar in 17 patients treated with cisplatin (dose
142-717, median 400 mg/m2), in 19 patients without
cisplatin and in 20 control subjects. A tendency (P <0.02) towards
increased plasma creatinine (79 (69-89) &mgr;mol/l; median and
interquartile range) and low plasma magnesium (0.80 (0.78-0.85) mmol/l) was
noted in patients treated with cisplatin as compared with those without
cisplatin (68 (58-80) &mgr;mol/l; 0.84 (0.79-0.90) mmol/l). No
correlation was noted between the dosage of cisplatin and circulating
magnesium or creatinine. Conclusions: The study
demonstrates that the permanent renal disturbances ((i) decreased renal
function and (ii) hypomagnesaemia) noted after treatment with cisplatin
during infancy or childhood are mild. Furthermore, the study does not
demonstrate renal sequelae in patients with the same malignancies who had
been treated without cisplatin. Key words: children;
chronic; cisplatin; kidney failure; magnesium deficiency
