Abstract:
Objective To study the epidemiological and clinical features of primary hyperthyroidism complicated with thyroid cancer.Methods Clinical data of 30 cases of hyperthyroidism complicated with thyroid cancer(hyperparathyroidism group)were retrospectively analyzed.They were chosen from the 365 cases of primary hyperparathyroidism treated by operation from Jan.2002 to Jun.2011.At the same time,30 cases of thyroid cancer without hyperparathyroidism were randomly taken out as the control group.Results The incidence of thyroid cancer in primary hyperparathyroidism was 8.22％ (30/365).The median course,preoperative diagnostic rate of thyroid cancer,and lymph nodes metastasis rate for hyperparathyroidism group and control group was 875.00 vs 120.00 days(z =-2.501,P ＜0.05),40.0％ (12/30) vs 66.7％ (20/30) (x2 =4.286,P ＜0.05),and 20.0％ (6/30) vs 46.7％ (14/30) (x2 =4.800,P ＜ 0.05) respectively.All patients were followed up with the average of 4.5 years,ranging from 1 month to 9 yeas and a half.1 case(3.3％)in hyperparathyroidism group recurred hyperthyroidism 5 years after surgery.1 case(3.3％)recurred thyroid cancer 1 year after surgery and received operation again,and 1 case(3.3％)died half a year after operation from respiratory failure caused by lung metastasis of thyroid cancer in the control group.Conclusions Hyperthyroidism complicated with thyroid cancer has the characteristics of high incidence rate of thyroid cancer in the hyperthyroidism patients,long course,high preoperative misdiagnosis rate,low lymph node metastasis rate,favorable prognosis and so on.
