A total of 221 consecutive early stage Hodgkin's disease (HD) patients were
given mantle held irradiation only or in combination with chemotherapy in
1971-1991. in 1991 these patients responded to a mailed self-report questio
nnaire covering items on late medical symptoms. Of 200 patients (91%) who r
eported that their thyroid function had been tested, 110 patients (55% of t
hose rested) had thyroid hypofunction at follow-up in 1994. Ninety-five pat
ients (86% of patients with biochemical hypothyreosis) had started hormonal
substitution. In 1993 and 1994. 101 of these patients who had received man
tle field irradiation in 1980-1988 were called in for interview. clinical e
xamination and thyroid function tests. Eighteen patients (18%) had started
hormonal substitution treatment earlier, but 58 (70%) of the other 83 patie
nts were found to have biochemical hypothyreosis. Of the 221 patients who c
ompleted the questionnaire, 66 patients (30%) reported dyspnoea on exertion
for more than 3 years after treatment, 8 patients (4%) reported a history
of myocardial infarction, 6 patients (3%) reported pericardial disease and
25 patients (11%) heart valve disease. Increased expenses incurred for dent
al care were reported by 106 patients (48%), increasing to 55% when Waldrye
r's ring had been irradiated. The consequences of late sequelae after mantl
e field irradiation for future treatment are discussed.
