Brief Summary
Background: Mexico City has one of the highest incidences and mortality rates of acute lymphoblastic leukemia (ALL) in the world and a high frequency of early relapses (17%) and early mortality (15%). Otherwise, childhood overweight and obesity are reaching epidemic proportions. They have been associated with poor outcomes in children with ALL. The aim of present study is to identify if overweight and obesity are prognostic factors associated with survival rates in Mexican children with ALL. Methods: Multicenter cohort study. ALL children younger than 15 years old are included and followed-up. Overweight and obesity are classified according World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) criteria. Deaths and relapses are the main outcomes.

Outcome Measures
Primary Outcomes (2)
Overall survival
Deaths of patients occurring during the follow-up period will be collected. The cause of death and the date that this occurred will be also registered. In the case of patients alive at the end of follow-up, the date of the last visit to the hospital will be collected.
year 5
Disease-free survival
Clinical data and by complementary examinations indicating that there is reappearance of the disease after complete remission has been achieved, presence of blasts \> 5% in bone marrow (bone marrow relapse) or presence of blasts in cerebrospinal fluid fluid (CNS relapse), testicular infiltration by blasts in the biopsy (testicular relapse), combined (bone marrow/CNS) at any time during treatment . In case the patient has relapsed, the site of relapse will be collected (bone marrow, CNS, testicle, ovary, eye, etc.).
year 5
Study Arms (1)
Overweight/Obesity
BMI at diagnosis will be used. Using WHO software (version 3.2.2, World Health Organization, Geneva), the BMI-for-age Z-scores were calculated for each patient. According to WHO classification, patients were categorized as normal (- 1.9999 to 0.9999), wasted (- 2 to - 2.9999), severely wasted (≥ - 3), at risk of overweight (1-1.9999), overweight (2 to 2.9999) and obesity (≥3). In addition, the BMI percentiles cutoffs provided by CDC were: normal (p5-84.9999), underweight (\< p5), overweight (p85-94.9999), and obese (≥ p95). The nutritional classification and measurements regarding weight and height recorded in clinical files will be used to classify patients' nutritional status in present research has been previously described.

Eligibility Criteria
The study variables and data will be collected from the clinical files. The information collected by the surveyors will be delivered weekly to our Research Unit, where the field work coordinators will be in charge of assigning them a folio number, reviewing the collection instrument and passing it on to the personnel in charge of capturing the information. In addition, the fieldwork coordinators will supervise the collection of information, the search for files in the archive, the capture of information and will be responsible for keeping the project's database up to date.
You may qualify if:
- Patients under 15 years of age
- Newly diagnosed with acute lymphoblastic leukemia
- Diagnosis confirmation by bone marrow aspiration and immunophenotype
- Attended in the participating Hospitals.
You may not qualify if:
- \- Patients with Down Syndrome (for being a population with different disease behavior and cytogenetic alterations than patients without this genetic condition)
