Childhood T-lineage acute lymphoblastic leukemia: management and outcome at a tertiary care center in North India.

Objective: To assess the clinical features, prognostic factors and outcome of childhood T-ALL in comparison with B-lineage ALL, treated with a uniform treatment regimen (MCP 841).

Setting: Pediatric oncology division of a tertiary care institution in Northern India.

Design: Retrospective analysis of clinical data and survival outcome.

Infections in childhood acute lymphoblastic leukemia: an analysis of 222 febrile neutropenic episodes.

A retrospective analysis was performed on febrile neutropenic episodes in patients with acute lymphoblastic leukemia (ALL) from 1992 to 2002. There were 222 febrile neutropenic episodes in 266 ALL patients with documented ANC < 500/mm(3). Of the 222 episodes, 98 (44%) had documented focus of infection; the rest were fever without focus.

Bone relapse in acute lymphoblastic leukemia.

Acute lymphoblastic leukemia (ALL) can occasionally relapse in unusual extramedullary sites like bone. Here we present a 6.5-year old boy with 'T' cell ALL who developed a swelling in left tibia which was infiltrated with lymphoblasts 7 months after completion of chemotherapy.

Non hodgkin's lymphoma seven years following remission of acute lymphoblastic leukemia.

The authors describe a case of extramedullary relapse in lymph node presenting as lymphoblastic lymphoma seven years following remission of acute lymphoblastic leukemia. To the best of our knowledge, this is the first reported case of an isolated lymph node relapse with hematopoietic remission of leukemia. We have discussed cases of large cell lymphoma and other unusual areas of extramedullary relapse complicating acute lymphoblastic leukemia in hematopoietic remission.
