Correlation of lymphangiography, computed tomography, and laparotomy in the staging of Hodgkin's disease.

Sombeck MD, Mendenhall NP, Kaude JV, et al.

Abstract:

Purpose:
To determine the predictive value of lymphangiography and computed tomography of the abdomen and pelvis for infradiaphragmatic involvement of Hodgkin's disease.

Methods:
AND

Method:
: We retrospectively reviewed the findings on 125 patients with Hodgkin's disease treated at the University of Florida who underwent lymphangiography and staging laparotomy; 33 patients also underwent computed tomography of the abdomen and pelvis. The positive predictive value and negative predictive value were calculated for both studies.

Results:
The positive predictive value of lymphangiography for paraaortic or pelvic disease was 35%, while the negative predictive value was 95%. The positive predictive value of computed tomography of the abdomen and pelvis for paraaortic or pelvic disease was 20%; the negative predictive value was 93%. There was no advantage in predicting paraaortic or pelvic disease when both studies were obtained as compared to either study alone. For splenic disease, the positive predictive value of computed tomography was 43%; the negative predictive value was 77%. Of the patients with a positive lymphangiography, 57% were found at laparotomy to have either no abdominal disease or upper abdominal disease only, with or without minimal splenic disease, making them reasonable candidates for radiotherapy alone. Of the patients with a negative lymphangiogram, 14% were found at laparotomy to have either lower abdominal disease or extensive splenic disease, and so were not good candidates for radiotherapy alone.

Conclusion:
We recommend laparotomy for patients who may be candidates for radiotherapy alone or combined modality therapy with limited chemotherapy.
