Cytostatics for acromegaly. Marked improvement in a patient with an invasive pituitary tumour.
A 21-year-old woman suffering from acromegaly was treated with transsphenoidal subtotal hypophysectomy (microscopy: acidophilic adenoma), followed by x-ray and bromocriptine therapy. Seven years later she was re-operated because of a partial bitemporal loss of vision, intracranial hypertension, and regrowth of the pituitary tumour seen on CT-scan. A large part of the invasive suprasellar tumour was then removed by transcranial approach. The neurosurgery was followed by cobalt radiotherapy and bromocriptine administration. Two years later, symptoms and signs of tumour growth reappeared. Administration of cytostatics, such as doxorubicin (Adriamycin) and lomustine (Belustine), resulted in distinct clinical improvement associated with a seven-fold decrease in the serum growth hormone concentration. The visual field became normal and the intracranial mass on a CT scan decreased markedly. As a result the patient was able to resume work.
