NCT05811169
To study and comprehend the evolutionary and genomic landscape between primary and metastatic sites and the dynamics of intratumour and intertumour heterogeneity over time with reference to the treatment modalities for each Chinese patient with non-small cell lung cancer.
NCT05811910
Therapeutic success in childhood ALL reaches an outstanding success that currently relies upon risk stratification of patients with appropriate modulation of chemotherapy intensity based on underlying blasts' biological and molecular characteristics, and depth of initial treatment response. ALL polychemotherapeutic approaches share similar therapeutic scheme, with more intensive and toxic earlier phases (about 6 months) followed by a prolonged immunosuppressive regimen for maintenance (about 18 months). Protocols comprise glucocorticoids, antimetabolites, asparaginase, alkylating agents, antimitotic drugs antibiotics and, in case of Philadelphia positive ALL, anti-tyrosine kinase inhibitors combined together at different dosages and timing according to the patient's class of risk. ALL chemotherapeutic agents can damage nearly all organs. Some adverse reactions are extensions of the drugs' desired pharmacological effects on bone marrow and affect almost all children. Other adverse effects occur unpredictably in a smaller fraction of patients who, for unknown reasons, are more susceptible. Concerns about chemotherapy-related toxicities generated a significant need of finding predictive markers for the a priori identification of at-risk patients. Pharmacogenomics markers can be useful tools in clinics for tailoring therapy intensity on patients' genetic profile and in basic research for better understanding mechanistic and regulatory pathways of the biological functions associated with ALL treatment toxicities. Several genome wide association studies explored the landscape of ALL treatment-associated toxicities, discovering the contribution of important variants. Among these, TPMT single nucleotide polymorphisms (SNPs) have a well-recognized role in thiopurine-induced myelotoxicity. SNP rs924607 (C\>T) in the promoter region of the gene encoding for the centrosomal protein 72 (CEP72) was associated with increased risk and severity of vincristine-related peripheral neuropathy. The aim of this study is to perform a GWAS in ALL children to provide insight into genetic loci affecting the occurrence of severe (grade III-V) vincristine-related peripheral neuropathy during induction therapy in the AIEOP protocols.
