7082 Background: Data on B cell Acute Lymphoblastic leukemia (ALL) in the poor prognostic age group of > 9 years from India is minimal. Methods: This is an analysis of patients of above 9 years that were diagnosed and treated from January 2000 to December 2010 at a single institute . All patients who completed at least 4 weeks of induction therapy were analysed for various outcomes. Results: Of the 241 newly registered patients, the median age was 19 years (Range 10-78 years) with an M:F ratio of 1.9:1. Out of this 47%, 25% & 28% patients belonged to 10-18, 19-30 & > 31 years age group respectively. Twenty seven (11.6%) and 5(2%) had CSF and testicular involvement respectively. Thirty nine per cent had a total leucocyte count (TLC) of above 30x109/L. Philadelphia chromosome (Ph) positivity was seen in 27% and was equally distributed among the different age groups. Patients available for outcome analysis were 213(88.4%). Complete remission rate (CRR) was 66.6% and induction mortality was 26.3%.At a median follow up of 65.8 months 5 year leukemia free survival was 30.5%. Seventy eight (55%) patients relapsed (median relapse time of 13.5 months, range 1.7 to 53.4 months) , 55% during maintenance phase. The 5 year overall survival (OS) was 30.3% with a median OS of 15.8 months. The OS was similar in 10-18 and 19-30 age groups (5 year OS 35% vs. 27.5%, p=0.641) but it was significantly lower in >31 years (5year OS 21%, p=0.008). Apart from this, extramedullary disease, not attaining a CR in 1st induction, albumin at presentation below 3.5gm% and TLC of >100x109/L were significant poor prognostic markers for survival. Conclusions: This is a large study of B-ALL outcomes in patients above 9 years from a single center in India. Patients above 30 years had a worse prognosis while the prognosis of 10-18 and 19-30 years age group were similar. Induction mortality was higher mainly because of advanced disease and poor performance status at presentation.

Disease Stratification

The genetic basis of leukemogenesis in adults with B-cell acute lymphoblastic leukemia (B-ALL) is largely unclear and its clinical outcome remains unsatisfactory. This study aimed to advance the understanding of biological characteristics, improve disease stratification, and identify molecular targets of adult B-ALL. Adolescents and young adults (AYA; 15-39 years old, n = 193) and adults (40-64 years old, n = 161) with Philadelphia chromosome-negative B-ALL were included in this study. Integrated transcriptomic and genetic analyses were used to classify the cohort into defined subtypes. Of the 323 cases included in the RNA sequencing analysis, 278 (86.1%) were classified into 18 subtypes. The ZNF384 subtype (22.6%) was the most prevalent, with two novel subtypes (CDX2-high and IDH1/2-mut) identified among cases not assigned to the established subtypes. The CDX2-high subtype (3.4%) was characterized by high expression of CDX2 and recurrent gain of chromosome 1q. The IDH1/2-mut subtype (1.9%) was defined by IDH1 R132C or IDH2 R140Q mutations with specific transcriptional and high-methylation profiles. Both subtypes showed poor prognosis and were considered inferior prognostic factors independent of clinical parameters. Comparison with a previously reported pediatric B-ALL cohort (n = 1003) showed that the frequencies of these subtypes were significantly higher in AYA/adults than in children. We delineated the genetic and transcriptomic landscape of adult B-ALL and identified two novel subtypes that predict poor disease outcomes. Our findings highlight the age-dependent distribution of subtypes, which partially accounts for the prognostic differences between adult and pediatric B-ALL.
