The diagnosis of leukemia in a child impacts the whole family, with disruption in their routines, behavior, attitudes and relationships, with long-term adverse psychosocial consequences. Comprehensive treatment of cancer involves not only the management of physical symptoms due to cancer but also attention to psychological, socio-cultural and spiritual domains of the child and family as a unit. Pediatric palliative care offers a holistic approach towards supporting the children and families during the entire course of treatment regardless of prognosis, and includes the full spectrum of physical, psychological, social, and spiritual care. Palliative care should go along with active cancer treatment and should be smoothly introduced to patients and their families, so that they do not feel abandoned by their treating teams if curative treatment is unsuccessful and palliative care teams are abruptly involved. Recent evidence proves that integration of palliative care is associated with significant improvements in the quality of life of children affected with cancer and their families, and should begin at diagnosis itself.

However, ALL in infants, though rare, is an exception, with its distinct aggressive disease biology, molecular genetics and poor response to therapy with an excess of relapses. It characteristically presents with hyperleukocytosis, bulky disease and a higher incidence of central nervous system (CNS) and cutaneous involvement. Immunophenotyping is notable for CD10 negativity, and higher co-expression of various myeloid markers indicating a primitive hematopoietic cell of origin. Rearrangement in <em>KMT2A</em> gene i.e. <em>KMTA</em>-r (previously <em>MLL</em>), located on 11q23, is central to disease pathophysiology, playing a key role in epigenetic modification that drives leukemogenesis, and is the strongest negative prognostic marker in this subgroup. Hyperleukocytosis with total leukocyte count exceeding 3,00,000/mm<sup>3</sup>, younger age group (<6 months age), poor prednisolone response and poor MRD response are other important negative prognostic markers in infant ALL.
