Assessment of the Long Term Outcome of Childhood ALL Patients Enrolled in EORTC Children's Leukemia Group Trials Between 1971 and 1998

OBJECTIVES:

• To assess the long-term outcomes (i.e., long-term survival, long-term disease status, occurrence of late adverse effects, occurrence of second cancers, and socioeconomic status of survivors) of patients with acute lymphoblastic leukemia previously enrolled as children on clinical trials EORTC-58741, EORTC-58831, EORTC-58832, or EORTC-58881 between the years of 1971 and 1998.

OUTLINE: Long-term outcome data are collected from the databases about clinical trials EORTC-58741, EORTC-58831, EORTC-58832, or EORTC-58881. Other data collected include the patient's vital status actualization (e.g., alive, dead or lost to follow up, date last known to be alive or date of death), medical records data, and the collection of data from patients confirmed to be alive (e.g., data related to marital status, education, work, insurance, puberty, fertility, and offspring) by questionnaire.
