Information provided by:	National Cancer Institute (NCI)
ClinicalTrials.gov Identifier:	NCT00993694

Purpose

RATIONALE: Gathering information about how often methemoglobinemia occurs in young patients receiving dapsone for hematologic cancer or aplastic anemia may help doctors learn more about the disease and plan the best treatment.

PURPOSE: This research study is looking at methemoglobinemia in young patients with hematologic cancer or aplastic anemia treated with dapsone.

Primary Outcome Measures:

Incidence of methemoglobinemia in patients with hematologic malignancy or aplastic anemia who received dapsone prophylaxis through a retrospective chart review encompassing the last 15 years [ Designated as safety issue: No ]
Major risk factors for developing methemoglobinemia [ Designated as safety issue: No ]

Estimated Enrollment:	200
Study Start Date:	January 2009
Estimated Primary Completion Date:	June 2010 (Final data collection date for primary outcome measure)

Detailed Description:

OBJECTIVES:

Define the incidence of methemoglobinemia in patients with hematologic malignancy or aplastic anemia who received dapsone prophylaxis through a retrospective chart review encompassing the last 15 years.
Identify major risk factors for developing methemoglobinemia.

OUTLINE: Medical charts are reviewed. Of particular interest is demographic information, reasons for beginning dapsone prophylaxis, duration of dapsone prophylaxis, dapsone dosing, methemoglobin level, and treatment with methylene blue.
