Diagnostic tests and Hodgkin's disease: a standardized approach to their evaluation.

We have analyzed a series of 124 young men with Hodgkin's Disease in an attempt to clarify the role of non-invasive tests in the staging evaluation. Data are presented in a way which permits comparison between series and application of the data to decision-making models. Analysis of the data shows our patients to have had primarily limited (stage I and II) disease. In our hands certain tests were quite accurate in predicting the absence of abdominal disease (lymphangiography, hepatic scintigraphy) as determined by laparotomy, but no study appeared to eliminate the need for laparotomy in this group. Data from several other large series are also presented in the same format. The data demonstrate a large variability between institutions in the predictive value of a positive lymphangiogram. Other studies, such as splenic scintigrams, appear to have more consistent predictive values. We encourage further use of this type of data presentation.
