Erythrocyte complement receptor type 1 (CR1) was measured in 37 normal controls and in 95 patients with various hematologic diseases. Levels of erythrocyte CR1 were significantly decreased in patients with acute myelocytic leukemia (AML), acute lymphocytic leukemia (ALL), chronic myelocytic leukemia, non-Hodgkin's lymphoma (NHL), aplastic anemia, idiopathic thrombocytopenic purpura, and multiple myeloma when compared to normal controls. There was also a trend of recovery of erythrocyte CR1 levels in AML and ALL patients when they were in a state of complete remission compared to those at time of onset or relapse. Further investigation is needed as to determine whether the level of erythrocyte CR1 can serve as a predictor for relapse of leukemia. This study also showed that the level of erythrocyte CR1 was not related to prognostic factors in NHL patients.

Circulating immune complexes (CIC) were measured by C1q-solid phase method in ninety-five patients with various hematologic diseases. The results showed significantly higher CIC levels in patients with acute myelocytic leukemia, chronic myelocytic leukemia, aplastic anemia and idiopathic thrombocytopenic purpura (ITP) than CIC levels in normal controls. However, there was no significant difference in such levels in patients with acute lymphocytic leukemia, non-Hodgkin's lymphoma and multiple myeloma when compared to normal controls. In this study, the level of CIC did not relate to prognosis for patients with non-Hodgkin's lymphoma. The findings demonstrated that a high level of CIC in patients with ITP usually responded poorly to steroid treatment. Other immunosuppressive agents were indicated in these cases. Therefore, the CIC level may serve as a therapeutic guide for the treatment of patients with ITP.

The benign phase of chronic myelogenous leukemia (CML) typically is characterized by an overproduction of myeloid cells that eventually progresses to a more acute stage termed blast crisis. This latter stage can exhibit either myeloid or lymphoid blast clones. Our recent results have demonstrated the presence of the P210 BCR-ABL protein in blood cells from benign phase CML patients (Guo et al., Cancer Research 51:3048, 1991). This protein is the product of an 8.5 kb chimeric RNA encoded by fused BCR-ABL genes produced by the formation of the Philadelphia (Ph) chromosome. Using this new assay we have identified a patient with benign-phase CML who produces P190 BCR-ABL, the form of the BCR-ABL protein found in about 50% of cases of acute lymphocytic leukemia (ALL). This patient lacked detectable P210 BCR-ABL protein and did not contain a DNA rearrangement in the major breakpoint cluster region of the BCR gene. Consistent with this result, polymerase chain reaction (PCR) analyses detected a BCR-ABL mRNA with BCR exon 1 fused to ABL exon 2. No BCR-ABL mRNAs with 2'- or 3'-bcr exon to ABL exon 2 fusions were detected in these analyses. Blood cells from this patient lost P190 BCR-ABL after the patient underwent an allogeneic bone marrow transplant, but regained this protein although the patient was still in chronic phase after a subsequent autologous transplant as treatment for graft failure. These findings indicate that P190 BCR-ABL alone is not sufficient to induce a blast crisis phenotype in leukemia patients who are Ph chromosome-positive.

Current chemotherapy will cure at least 65% of children with acute lymphoblastic leukemia (ALL). The major challenge in ALL is to develop effective risk-directed therapy. This approach seeks to improve outcome, through more intensive therapy, for children at high risk of relapse, while reducing the side effects and long-term complications of treatment for those with a high likelihood of cure. The prognosis remains poor for most children with acute myeloid leukemia (AML). Despite the use of intensive chemotherapy and bone marrow transplantation, only 30% to 40% of these patients are long-term survivors. However, research has identified subgroups of patients who will respond well to therapy that is targeted to their specific biologic subtype of AML. Allogeneic bone marrow transplantation remains the only curative treatment for patients with chronic myeloid leukemia. Current efforts focus on improving risk-directed and subtype-specific treatment for the childhood leukemias. Ultimately, it may be possible to target treatments to the specific genetic lesions of leukemic cells.
