@entity259 usually have a good prognosis, particularly well-differentiated @entity5 confined to the gland. An analysis was made of the treatment and prognosis of @entity259 with invasion of the upper respiratory and digestive tract. Of 211 @entity1 treated at our institution from 1975 to 1994, only 18 had invasion of the upper respiratory and digestive system. All @entity1 were treated surgically. The procedures included total thyroidectomy, laryngectomy, partial esophagectomy, and tracheal resection. The @entity5 recurred locally after complete resection in 33%. Cervical lymph node @entity3 occurred in 17% and distant @entity3 in 33%. The 5-year survival rate was 46% for well-differentiated @entity189 . Invasion of the respiratory and digestive tract had negative prognostic significance in the statistical analysis. Locally advanced @entity259 had a poorer prognosis than those limited to the thyroid gland. However, complete surgical resection of the @entity5 was achieved in most @entity1 without functionally mutilating procedures and with satisfactory survival results.
