Radiotherapy in the treatment of XXXX .

@entity1 @entity41 @entity5 @entity977 @entity970
Between 1970 and 1985, 145 @entity1 were treated for @entity977 and 126 @entity1 were available for analysis. Sixty @entity1 were treated with surgery alone (Group I), 54 were treated with surgery and radiation therapy (Group II), and 12 received irradiation only without tissue diagnosis (Group III). Extent of @entity5 was evaluated by CT scan, @entity970 , and surgical reports. There were 22 microadenomas in Group I and only 1 microadenoma in Group II. The mean follow-up was 6.4 years, 85% (51/60) of @entity1 in Group I, 93% of @entity1 in Group II, and only 50% of those treated with irradiation alone achieved @entity5 control. With subsequent salvage treatment, @entity5 control in Group I was 97%. The mean time to recurrence was 3.7 years (Group I), 4.5 years (Group II), and 4 years (Group III). In summary, combined treatment is effective to decrease the chance of local recurrence of @entity977 . Nevertheless, because of successful salvage treatment after surgical failure, overall outcome is similar. Without persistent symptom after surgery or large @entity41 in or near the critical structures, postoperative irradiation can be deferred until @entity5 regrowth.
