Bew. Brownlie et al., PRIMARY THYROID LYMPHOMA - CLINICAL-FEATURES, TREATMENT AND OUTCOME -A REPORT OF 8 CASES, New Zealand medical journal, 107(983), 1994, pp. 301-304
Aim. To assess the clinical findings and response to treatment of pati
ents with primary thyroid lymphoma. Methods. Patients with primary thy
roid lymphoma were identified by reviewing the diagnoses of all patien
ts with thyroid malignancies diagnosed at Christchurch Hospital betwee
n 1980-91. The records of patients with primary thyroid lymphoma were
abstracted. Results. During the 12 year period eight patients (6 femal
es, 2 males) with primary thyroid lymphoma were diagnosed and treated.
The median age was 78 years (range 18-90 yr). All patients presented
with recent thyroid masses and obstructive symptoms were prominent. Tw
o patients were initially referred with endocrine dysfunction - one th
yrotoxic and one hypothyroid. Six patients had nonHodgkin lymphoma and
two Hodgkin's disease, with all having stage IA disease. Two patients
were treated by thyroidectomy, and in the remaining six patients the
thyroid lymphoma masses regressed following radiotherapy with the two
youngest patients also receiving chemotherapy. At follow up all five e
lderly patients have since died - two of disseminated lymphoma, two of
concurrent cancers and one of vascular disease, and the three younger
patients remain in remission after 4.5, 6.5 and 10.5 years. Conclusio
n. Primary thyroid lymphoma usually presents with obstructive symptoms
, but there may be associated thyroid dysfunction. Thyroid lymphoma ma
sses respond well to radiotherapy.
