Late effects of childhood cancer treatment in long-term survivors diagnosed before the age of 3 years - A multicenter, nationwide study.

Background: The effect of age on the incidence of late sequelae that occur after anticancer treatment in childhood is still not fully elucidated. In this multicenter study of long-term survivors diagnosed before age of three, we investigated the prevalence of late effects many years after treatment.

Methods: The study group (n = 561) was selected from the Polish National Childhood Cancer Survivors Registry (n = 1761) created in 2007.

The influence of different intensity of treatment on hormonal markers of gonadal function in acute lymphoblastic leukemia survivors.

Anti-cancer treatment in children can deteriorate gonadal function and affect future fertility. We analyzed the hormonal markers of gonadal function in adolescent leukemia survivors, treated in childhood with different levels of aggressiveness. We analyzed hormone levels in 69 adolescents and young adults, leukemia survivors stratified into standard (SR), intermediate (IR), and high (HR) risk groups, and in 80 healthy controls (38 men) at a similar age.

Health status of Polish children and adolescents after cancer treatment.

Unlabelled: In the last 40 years, considerable progress was made in the treatment of childhood cancer. Nearly 80% of children achieve long-term clinical remission or are permanently cured. This improvement is however not without sacrifice.

Pearson marrow pancreas syndrome in patients suspected to have Diamond-Blackfan anemia.

Pearson marrow pancreas syndrome (PS) is a multisystem disorder caused by mitochondrial DNA (mtDNA) deletions. Diamond-Blackfan anemia (DBA) is a congenital hypoproliferative anemia in which mutations in ribosomal protein genes and GATA1 have been implicated. Both syndromes share several features including early onset of severe anemia, variable nonhematologic manifestations, sporadic genetic occurrence, and occasional spontaneous hematologic improvement.
