Significance of splenomegaly in childhood Hodgkin disease.

AbstractOBJECTIVES:
Spleen involvement in childhood Hodgkin disease (HD) has not been described extensively. The authors' purpose was to study the clinicoradiologic features and prognostic significance of splenomegaly and that of splenic involvement in childhood HD.
METHODS:
One hundred forty-one children presenting with HD between January 1991 and February 2001 and treated with chemotherapy alone (4 COPP/4 ABVD) were included in the study. Radiotherapy was given in four patients with residual mediastinal disease. Patients were staged clinically and assessed for splenic deposits by computed tomography, ultrasonography, or both.
RESULTS:
Splenic involvement was seen in 22 children (15.6%). On univariate analysis, spleen deposits were significantly correlated with constitutional symptoms (P = 0.02), splenomegaly on physical examination (P < 0.001), involvement of three or more lymph node areas (P = 0.006), involvement of subdiaphragmatic lymph nodes (P = 0.01), mediastinal involvement (P = 0.001), and bulky disease (P = 0.005). Multivariate analysis retained enlarged spleen, involvement of three or more lymph node areas, and bulky disease as significant risk factors for spleen involvement. Relapse occurred significantly more in children with splenic involvement (P = 0.04) and in those with splenomegaly (P = 0.04). Presence of splenic deposits was an adverse prognostic factor for 5-year event-free survival (67.5% vs. 93.0%, P = 0.01).
CONCLUSIONS:
Enlarged spleen, involvement of three or more lymph node areas, and bulky disease are predictable risk factors for HD splenic deposits. Splenic involvement on computed tomography scan or ultrasonography is significantly associated with relapse and contributes to a poorer outcome of HD in children treated with chemotherapy alone.
