Determinants and outcome of T lineage acute lymphoblastic leukemia in India.

Authors report that the percentage of T lineage ALL at their institution is 14.2%, which is much lower than most previous reports form India. It would be very important to know the socioeconomic distribution of the families presenting with T lineage ALL at their predominantly non-public funded institution. It has been recently shown by investigators from Chennai that improvement in and hence; higher socioeconomic status is associated with a lower frequency of T lineage immunophenotype [2]. Differences, in socioeconomic strata, could partly or fully explain this disparity. Moreover, robust conclusions about the percentage of T lineage ALL are difficult due to small sample size in the authors study.
