Cohort Demographics
The clinical and pathological features of the cohort consisting of 60
patients of neuroblastoma are previously
published.15 Our cohort had older age, slight male
preponderance, and a higher stage at presentation. The most common
subtype was poorly differentiated neuroblastoma (55%, 33/60) followed
by undifferentiated neuroblastoma (42%, 25/60) and ganglioneuroblastoma
(3%, 2/60). There was no case of differentiating neuroblastoma in this
cohort. MKI could not be evaluated on smears in 10 cases due to poor
smear quality, low cellularity and/or crushing artifact. In the
remaining 50 cases, MKI was high in 39, intermediate in 4, and low in 7
cases. Prognostic evaluation by age combined with cytomorphological type
and MKI was applied, and as per INPC, the majority had unfavorable
cyto-histology (n=52, 87%) compared to favorable cyto-histology
(n=8,13)
