Achievement of complete molecular response in patients with chronic phase chronic myeloid leukemia has been recognized as an important milestone in therapy cessation and treatment-free remission; the identification of predictors of complete molecular response in these patients is, therefore, important. This study evaluated complete molecular response rates in imatinib-treated chronic phase chro...

Hybrid cell lines were obtained after fusion of mouse myeloid cells (WEHI-TG) with leukocytes from two patients with chronic myeloid leukemia. A third fusion was carried out with leukocytes from a patient with acute lymphocytic leukemia. All three patients carried the Philadelphia chromosome (Ph1) in the leukemia cell population. Cytochemical analysis confirmed the myelo-monocytic nature of the...
