Background: Modern treatment of oncological diseases increases markedly the chance of long-term survival and permanent recovery. Due to frequently highly aggressive treatment it is however associated with the risk of late sequelae in the surviving patients. Comprehensive care of patients includes therefore not only control of the neoplastic disease but also efforts of maximal improvement of the quality of life of the patients. In young subjects, in view of their long-term perspective, this problem is particularly important.
Methods and results: In 32 patients (25 boys and 7 girls) with extracranial solid tumours without primary endocrinological symptomatology (m. Hodgkin, neuroblastoma, ganglioneuroblastoma, nephroblastoma, Ewings sarcoma and others) a single examination was made assessing height, body weight, grade of sexual maturation according to Tanner, in boys testicular volume by means of a orchidometer and 20 other anthropometric dimensions. The mean age at the time of examination was 16.5 +/- 4.1 years, the mean age at the onset of treatment 6.1 +/- 4.8 years. The patients height, -0.4 +/- 0.9 SD, differs from the Czech national standard (p = 0.025). Impaired growth was recorded in 12.5% patients and had heterogenous causes. The authors proved a negative effect of radiotherapy on the growth of the spine, most markedly in children subjected to irradiation of the abdomen and chest and a highly significant reduction of the testicular volume in boys after cytostatic treatment of m. Hodgkin.
Conclusions: The results are consistent with studies made abroad and indicate the necessity of comprehensive long-term follow-up of somatic growth and development of the gonads in oncological child patients.
