الوصف: International audience ; PURPOSE: Pediatric T-cell lymphoblastic lymphomas (T-LBL) are commonly treated on T-cell acute lymphoblastic leukemia (T-ALL) -derived protocols. Therapeutic stratification based on response to the prephase treatment and on minimal residual disease assessment is well established in T-ALL but is not easy to extrapolate to T-LBL. The identification of molecular prognostic markers at diagnosis in T-LBL could provide an alternative for early therapeutic stratification. Our study determines the frequency and prognostic value of NOTCH1/FBXW7 mutations (N/F(mut)), FLASH deletion at chromosome 6q, and TCR rearrangements in a prospective cohort of pediatric T-LBL. PATIENTS AND METHODS: Pathologic samples were obtained at diagnosis for 54 patients treated according to the EuroLB02 protocol in France. N/F(mut) were identified by direct sequencing and allelic dosage was used to detect FLASH and TCRγ deletions, which were interpreted in conjunction with TCRγ, TCRβ, and TCRδ rearrangements. RESULTS: N/F(mut) were found in 55% of T-LBL patients, in whom they were associated with improved event-free survival (P < .01) and overall survival (P < .01). FLASH monoallelic deletions were observed in 18% of patients; they were predominantly N/F wild-type (six of nine) and tended to be of inferior prognosis (P = .09). Absence of biallelic TCRγ deletion (ABD) was seen in 7%, all of which were N/F(mut) and identified a poor prognosis group (P = .02). On multivariate analysis of N/F(mut), TCRγ ABD, and FLASH deletion, only N/F(mut) was an independent factor for good prognosis. CONCLUSION: Mutational status of NOTCH1/FBXW7 represents a promising marker for early therapeutic stratification in pediatric T-LBL.
