A variant Philadelphia chromosome (Ph1) positive chronic myelocytic leukemia.
A rare case of variant Philadelphia (Ph1) chromosome positive [46, XX, t (9; 22) (q34; q11), inv (9) (9q22; 22q13)] chronic myelocytic leukemia (CML) was described. The patient, 73 years old female, was hospitalized to our hospital because of leukocytosis. Hematological findings corresponded to those of CMLs. However, this case lacked hepatosplenomegaly. Southern blot analysis using a 3 breakpo...
متن کاملSister chromatid exchange in Philadelphia chromosome (Ph1)-positive leukemia.
The sister chromatid exchange (SCE) frequency was studied in the leukemic cells of 12 patients, 10 with Philadelphia chromosome (Ph1)-positive chronic myelocytic leukemia (CML), 1 with Ph1-negative CML, and 1 with acute myeloblastic leukemia. Except for two patients in the blastic phase of CML, the SCE values were within the normal range [3.8 +/- 6.4 (S.D.) SCE/cell; normal is 3.3 +/- 2.2 SCE/c...
متن کاملSignificance of Ph1-negative marrow cells in Ph1-positive chronic granulocytic leukemia.
Fifty-six of 195 Ph1-positive patients with chronic granulocytic leukemia were found to have Ph1-negative metaphases in marrow aspirates on one or more occasions. In 22 cases, Ph1-negative cells were found prior to initiation of antileukemic therapy. Five patients were in the blastic stage of the disease when Ph1-negative mitoses were seen. The finding of Ph1-negative cells appeared to be relat...
متن کاملPhiladelphia chromosome (Ph1)-negative chronic myelogenous leukemia (CML): a clonal disease with origin in a multipotent stem cell.
It has been shown with glucose 6-phosphate dehydrogenase (G-6-PD) mosaicism that Ph1-positive chronic myelogenous leukemia (CML) is a clonal disease that involves multipotent hematopoietic stem cells. We now report G-6-PD studies of a 79-yr-old woman with Ph1-negative CML. Equal amounts of B and A-type activities were found in nonhematopoietic tissues, indicating that the patient was heterozygo...
متن کاملIncidence of involvement of the B and T lymphocyte lineages in chronic myelogenous leukemia.
Peripheral blood specimens were obtained from 22 patients with Philadelphia chromosome (Ph1) positive chronic myelogenous leukemia (CML) (16 in chronic phase, 2 in an accelerated phase, and 4 in blast crisis). Studies were performed to determine the frequency of the presence of the Ph1 chromosome in cells of lymphoid lineages. Rosetted (E+) lymphocytes (T lymphocytes) from nine patients in chro...
