Abstract
BACKGROUND: The long-term survival of patients treated for Hodgkin`s disease (HD) in childhood is high and the chief concern is now being directed toward the late effects of the treatment, including the endocrine dysfunction. PATIENTS AND METHODS.: Testicular and ovarian functions were assessed in 64 long term survivors (24 females, 40 males) treated for HD in childhood in Slovenia between 1972 and 1994. At diagnosis they were 3-16 years old and had gonadal evaluation 4-27 years later at the age of 13-34. Fifty-four (84%) patients received chemotherapy (ChT), 49 in combination with radiation therapy (RT), 10 received RT alone. Gonadal function was assessed by the clinical examination and measurement of serum concentrations of estradiol and testosterone. Serum levels of LH and FSH were determined in the basal state and after the stimulation. RESULTS: Primary hypogonadism (PH) was found in 30 (47%) patients. Twenty-four of 40 (60%) males had PH with evidence of damage of germinal epithelium, 4 of them had evidence of damage of Leydig cells (LC) and 10 had evidence of dysfunction of LC as well. PH was found in 6 of 24 (25%) females. CONCLUSIONS: After therapy for HD PH was more frequent in males than in females. Not only RT but also alkylating agents and procarbazine alone caused damage of LC. Age of patient at the time of treatment was not an important risk factor for gonadal toxicity. Pelvic RT in combination with ChT is the most important risk factor of the development PH both, in males and females.
