Interactive Survivorship Program for the Improvement of Healthcare Resources in Adolescent and Young Adult Cancer Survivors, INSPIRE-AYA Study

Project description:This trial studies how well an interactive survivorship program works in improving healthcare resources in adolescent and young adult cancer survivors. By improving access to survivorship resources, health literacy, self-management skills, and support, an interactive survivorship program may help to improve adherence to adolescent and young adult healthcare guidelines and reduce cancer-related distress.

The BurnAlong Pilot Study for Adolescent and Young Adult Cancer Survivors

Project description:The purpose of this prospective, interventional, single-arm pilot study is to evaluate whether virtually delivered group-based physical activity is feasible for adolescent and young adult (AYA) cancer survivors. AYAs who were diagnosed with cancer and have completed cancer treatment will be recruited for this study. This study will enroll 20 participants in total and will last approximately 3 months.

miRNA expression profile in pediatric and adolescent and young adult rhabdomyosarcomas

Project description:Adolescents and young adults (AYA) with rhabdomyosarcoma (RMS) form a subgroup of patients whose optimal clinical management and best possible access to care remain a challenge and survival lacks behind that of children while diagnosed with histologically similar tumors. Understanding the tumor biology that differentiate children from AYA-RMS could provide critical information and drive new initiatives to improve their final outcome. MiRNA profile was evaluated in a RMS series of 49 tumor and 13 non-neoplastic tissues. MiRNAs analysis identified miR-223 over-expression and mir-431 down-regulation in AYA, validated by Real-Time PCR and miRNA ISH.

Gene expression profiling in pediatric and adolescent and young adult rhabdomyosarcomas

Project description:Adolescents and young adults (AYA) with rhabdomyosarcoma (RMS) form a subgroup of patients whose optimal clinical management and best possible access to care remain a challenge and survival lacks behind that of children while diagnosed with histologically similar tumors. Understanding the tumor biology that differentiate children from AYA-RMS could provide critical information and drive new initiatives to improve their final outcome. Gene expression profiling was evaluated in a RMS series of 48 tumor and 13 non-neoplastic tissues. GEP analysis detected 793 age-correlated genes in tumors. NOTCH2, FGFR1 were significantly down-modulated in AYA-RMS. GEP showed an increase in CD4 memory resting cells and a decrease in γδ T-cells in AYA-RMS. IHC analysis demonstrated an increase of infiltrated CD4, CD8 and neutrophils in AYA-RMS tumors.

Adult and adolescent acute lymphoblastic leukemia

Project description:We present here a genome-wide map of abnormalities found in diagnostic samples from 45 adults and adolescents with acute lymphoblastic leukemia (ALL). 500K single nucleotide polymorphism (SNP) array analysis uncovered frequent genetic abnormalities, with cryptic deletions constituting half of the detected changes, implying that microdeletions are a characteristic feature of this malignancy. Importantly, the pattern of deletions resembled that recently reported in pediatric ALL, suggesting that adult, adolescent, and childhood cases may be more similar on the genetic level than previously thought. Thus, 70% of the cases displayed deletion of one or more of the CDKN2A, PAX5, IKZF1, ETV6, RB1, and EBF1 genes. Furthermore, several genes not previously implicated in the pathogenesis of ALL were identified as possible recurrent targets of deletion. In total, the SNP array analysis identified 367 genetic abnormalities not corresponding to known copy number polymorphisms, with all but two cases (96%) displaying at least one cryptic change. This SNP array study is the first to specifically address adult and adolescent ALL, and the resolution level is the highest used to date to investigate a malignant hematologic disorder. Our findings provide insights into the leukemogenic process and may be clinically important in adult and adolescent ALL. Most importantly, we report that microdeletions of key genes appear to be a common, characteristic feature of ALL that is shared between different clinical, morphological, and cytogenetic subgroups. Keywords: Genomic analysis of acute lymphoblastic leukemia samples
