Abstract

To analyze the rates of concordance in the diagnosis of various hematological malignancies among patients referred to a tertiary cancer center, comparing the referring diagnosis with the final diagnosis at the M.D. Anderson Cancer Center. This was a cross-sectional study analyzing the 409 patients referred to the M.D. Anderson Leukemia Service in 1995 in whom a bone marrow examination was performed by the referring physician and in whom this examination was repeated at our institution. We also analyzed 100 cases, including 84 of the 409 referred patients for whom the diagnostic outside bone marrow slide had been sent for review. The overall concordance rate was 73%. In 18% discordances were present and considered of major importance (affecting treatment and/or prognosis) while in 9% there were minor discordances. Major discordance rates were 2% for chronic lymphocytic leukemic leukemia and 5% for chronic myelogenous leukemia, but 29% for acute myelogenous leukemia (79 patients), 43% for acute promyelocytic leukemia (7 patients), 19% for acute lymphocytic leukemia (42 patients), 57% for hairy cell leukemia (7 patients), and 23% for the myelodysplastic syndromes (75 patients). The concordance rate was 76% in the 100 cases in whic...Continue Reading

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
