Follow-up in 103 patients with catecholamine-secreting tumours

103 patients from a group of 115 patients with catecholamine secreting tumours were reinvestigated 7.0 +/- 4.9 years following surgery. Throughout the follow-up period 15 patients had died. In four of them death was definitively, in seven subjects possibly associated to the primary endocrine disorder. Following surgery improvement of general well-being was documented in 85% of the patients. Hypertension was corrected in 61 %, but 26% of the patients remained hypertensive and symptoms of hypotension like orthostasis developed in 24%. A significant increase in weight (> 5 kg) was observed in 26% of the subjects throughout the follow-up period, but did not result in a higher prevalence of diabetes mellitus which had to be treated in 16% of the patients before and only 14% following surgery. However, palpitations, increased sweating and headache persisted in 16%, 17% and 12% of the patients, respectively. Symptoms of cardiac insufficiency developed in 32%. Persistent discomfort related to the scar was reported by 55% of the patients following lumbar surgery and by 30% of the subjects that were operated on via a transabdominal approach. Hence we conclude that surgery of catecholamine-secreting tumours results in an improvement of health and well-being in most subjects according to objective criteria as well as to the judgement of the patients themselves.
