[Splenectomy in four cases of hairy cell leukemia]

This paper reports the experimental diagnosis of hairy cell leukemia and the results of splenectomy in 4 cases. Three patients were examined using histochemical methods and anti-leukocyte differentiation monoclonal antibodies. All of them were diagnosed as hairy cell leukemia of B lymphocytes. The effects of splenectomy were found to be related to chemotherapy used before and after operation. Hairy cell leukemia complicated with megalosplenia or hypersplenism were indications for splenectomy.
