“SOCIOECONOMIC FACTORS AFFECTING SURVIVAL IN CHILDREN WITH ACUTE LYMPHOBLASTIC LEUKEMIA FROM NORTH-EAST INDIA”

Acute lymphoblastic leukemia (ALL) is a highly curable childhood cancer with a survival rate of nearly 80% in developed countries but is around 45% in developing countries. This retrospective study analyzed the association between demographic and socioeconomic factors with survival in pediatric ALL. All confirmed cases of pediatric ALL (age <18 years) registered at Dr. B Borooah Cancer Institute between 2010 to 2017 were analyzed using data collected from hospital-based cancer registry and case records. Seventy-five confirmed cases of pediatrics ALL were eligible for the study. The median age of presentation was six years with a male: female ratio 1.9:1. Overall survival at 4-years was 43.8%, with a median survival of 25 months. A trend for higher 4-year overall survival was seen in female children (54.1% versus 37.9%, p=0.097). Patients from rural areas (44% versus 39.5%, p=0.308), with higher maternal education (83.3% versus 41.1%, p=0.161) and patients who did not abandon treatment (49.1% versus 31.2%, p=0.497) had better survival, but the differences were not significant. Four years overall survival in upper-middle, lower-middle, upper-lower, and lower class were 85.7%, 74.9%, 38.1%, and 7.7% respectively (upper-middleversus lower socioeconomic class, p=0.0001).Multivariate analyses confirmed a statistically significant relationship between socioeconomic status and survival, with the upper-middle group had a 90% decreased risk of death compared to the lower socioeconomic group. There is an urgent need for a proper definition of the problems of childhood ALL to introduce appropriate policies for improving survival in developing countries.
