Taking into account the specificities of adolescent and young adult cancer patients led agencies (in particular the French National Cancer Institute INCa, through the last Cancer Plan), to initiate projects targeting this population. Acute leukemia is among the most common cancers in adolescents and young adults. Recent therapeutic advances now allow hope for a cure in about 50% of this population. The issue of post-cancer is therefore of particular importance for young adults with cancer. Our aim is to establish the health determinants in young adult leukemia survivors and to compare the frequency of these effects and their explanatory factors to the data collected in children or adolescent leukemia survivors program (LEA). 90 patients followed up at the Institut Paoli-Calmettes cancer center and Nice University Hospital have been identified and would be included in this study.Collected data will include information on the initial disease and its treatments, physical sequelae (fertility, thyroid function, heart function, visual function, secondary tumors, viral infections, lung function, bone metabolism, iron metabolism, metabolic syndrome, osteonecrosis, alopecia ... ), quality of life, social and occupational integration and relationship with care system.

Inclusion Criteria:

• Young adult (18-40 years) Leukemia survivor, in complete remission.
• Acute leukemia diagnosed since January 1980 .
• Patient Affiliated to social security or beneficiary
• Signed Informed Consent prior to any screening procedures

Exclusion Criteria:
