title: Tonsillectomy: a prognostic factor in Hodgkin's disease?
abstract: The clinical features and course of Hodgkin's disease (HD) were investigated in 160 previously tonsillectomized patients and compared with 375 nontonsillectomized ones. In both groups, sex, social class, histologic type, stage and symptoms were almost identically distributed. Tonsillectomized patients showed a higher incidence of initial cervical forms (p less than 0.05) and more frequently developed the disease under 35 years of age (p less than 0.001), thus also reflecting the different policies of the otolaryngologists in the past few decades. Moreover, the tonsillectomized patients enjoyed a significantly better survival (p approximately equal to 0.01) than the nontonsillectomized ones. Adjusted survival curves for age and site of initial involvement proved that the favorable prognostic value of tonsillectomy was not due to the altered distribution of these 2 factors in the 2 groups; in addition, an earlier diagnosis in tonsillectomized patients could be excluded. The favorable effect of tonsillectomy in HD patients might be related specifically to the reduced portion of immunologically reacting oropharyngeal lymphoid tissue remaining after tonsillectomy. A decreased output of the specific immune-complexes, which are responsible for the disease, according to Vianna's theory, might be hypothesized in tonsillectomized patients.
