Dear Editor,

Philadelphia chromosomal (Ph+) abnormality is seen in 25% of adult and 3–5% of pediatric acute lymphoblastic leukemia (ALL) patients and is associated with high relapse rates [1]. Consolidation with HLA matched or Haplo-idential Allogeneic Stem Cell Transplantation (HaSCT) has been associated with better outcome in adult Ph + ALL patients [2, 3].

We are presenting our experience of HaSCT (HLAs matched at 5–8/10 of sibling or parents) for Ph + ALL patients from January-2012 to December-2017. Patients were followed up till 30-September-2018.

Out of 58 Ph + ALL patients during study period 10 patients (males = 6, median age 27.5 years, 17–42 years) received HaSCT after achieving first or second complete remission following intensive chemotherapy and tyrosine kinase inhibitor (Imatinib = 1, Dasatinib = 9). Six patients had Philadelphia chromosome while all patients had BCR-ABL detected by PCR. At the time of HaSCT, 5 patients were in CR1 and remaining in CR2. Eight patients...
