Effects of splenectomy on the general state and prognosis of patients with hematological proliferative disorders
open access
Abstract
Material and methods: Splenectomy was performed in 50 patients with various hematological proliferative disorders. The main indications were: compression symptoms, hypersplenism and diagnostic excision. The post-splenectomy observation period ranged from 6 to 82 months (mean time 26 months).
Results: An improvement lasting not less than 6 months was achieved in 52% of patients. The best prognosis group included patients with a primary splenic marginal zone lymphoma; 5 long lasting clinical remissions and 3 deaths due to basic disease progression were reported (altogether 15 cases). The worst prognosis group included patients with primary myelofibrosis — no clinical remission was reported and 6 deaths occurred due to disease progression (out of 9 cases). A splenectomy due to hypersplenism resulted in an platelet increase of over 100 × 109/l (89% of patients) and white blood cell increases of over 3 × 109/l (all patients). The post-splenectomy mean increase of the red blood cell count in patients with hypersplenism was not large (0.07 × 1012/l). In two patients however, it reached 0.7 and 1.7 × 1012/ therefore blood transfusion could be avoided. In 22% of patients, serious post splenectomy clinical complications appeared including one death due to a cerebral hemorrhage. In 50% of patients thrombocytemia was observed and in 28% of patients, an asymptomatic thrombosis of the splenic vein occurred.
Conclusions: The best prognosis in patients with proliferative hematological disorders was found in the group with primary splenic marginal zone lymphoma, while respectively the worst prognosis concerned patients with primary myelofibrosis.
