Second Malignant Neoplasms After Childhood ALL Therapy (PdL-SMN1)

May 23, 2012 updated by: Kjeld Schmiegelow, Rigshospitalet, Denmark

Second Malignant Neoplasms After Childhood ALL Therapy; An International Ponte di Legno Study

Development of a second neoplasm (SMN) during or after therapy for childhood acute lymphoblastic leukemia (ALL) is a rare event generally associated with a poor prognosis. In this international study we analyze subtypes of SMN in relation to their initial leukemia characteristics and treatment, and their subsequent overall survival.

Study Overview

Status

Completed

Detailed Description

To explore epidemiology, potential risk factors and survival rates of second cancers occurring as the first event in childhood acute lymphoblastic leukemia the involved study groups will collect anonymous data on all such cases diagnosed within the last decades to form a common database with predefined variables comprising the clinical, biological, and cytogenetic characteristics (myeloid neoplasias only) as well as outcome. Furthermore, we will register the clinical, biological, and cytogenetic characteristics of the acute lymphoblastic leukemia as well as type of treatment given.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pattern of SMN subtypes
Time Frame: At 20 years from diagnosis
Pattern of the main groups of SMN and their clinical charactiristics
At 20 years from diagnosis
Overall survival by subtype
Time Frame: At 10 years from diagnosis of SMN
Overall survival by the main SMN subtypes (myeloid malignancies, brain tumors, lymphomas, sarcomas, carcinomas, others)
At 10 years from diagnosis of SMN
Risk factors for development of SMN
Time Frame: At 20 years from ALL diagnosis
Identification of risk factors linked to the interval to SMN, the subtype of SMN, and the survival after. These risk factors are clinical characteristics of ALL or the anti-ALL therapy administered
At 20 years from ALL diagnosis
