Total body irradiation of chronic lymphocytic leukemia. Relationship between therapeutic response and prognosis.
There is lack of evidence to date that treatment of chronic lymphocytic leukemia (CLL) alters the natural history of disease or influences survival. In the present series, total body irradiation (TBI) produced a range of therapeutic responses among patients with active, progressive CLL. One-third of patients experienced virtually complete clinical and hematologic remissions with the initial course of TBI. These patients did not differ from the less complete responders with respect to age or sex, degree of lymphocytosis in the peripheral blood, incidence of anemia and/or thrombocytopenia, or the frequency of constitutional symptoms. However, the patients with complete remissions noted a return to normal performance status, had fewer serious infections, demonstrated recovery from depressed immunoglobulin levels, and had significantly longer survival. These data indicate that TBI is capable of inducing remissions which modify the course of disease in patients with CLL and that prognosis has a direct correlation with the response to therapy.
