Five years follow-up study was performed in 279 patients who were operated for benign thyroid tumor in 1974 at Ito Hospital. The recurrence of tumor was diagnosed in 42 of 279 patients (15%) by palpation. The incidences of recurrence in 106 patients with adenoma, 135 patients with adenomatous goiter and 38 patients with cyst divided by pathological diagnosis of first operation were 8.5%, 20.7% and 10.5% respectively. From a standpoint of type of surgery, the incidences of recurrence in patients with adenomatous goiter were 10.0% in 50 cases with subtotal thyroidectomy, 26.8% in 41 cases with enucleation, 27.3% in 44 cases with hemithyroidectomy.
In addition, a relationship between histological findings of primary and recurrent tumor was investigated in 46 reoperated cases in 1978, whose pathological diagnosis was benign thyroid tumor. While 24 of 46 cases was diagnosed as adenomatous goiter at first operation, the diagnosis of adenomatous goiter was made in 43 of 46 cases at second operation.
These findings suggest that 1) it is necessary to examine an existence of adenomatous change in a benign thyroid tumor and 2) the subtotal thyroidectomy should be performed, if a diagnosis was made as adenomatous goiter.
