Clinico-histopathological Profile of Primary Paediatric Intra-abdominal Tumours: a Multi-hospital-Based Study.

Paediatric cancers are gradually on the rise in India. Its proportion among children aged < 15 years constitutes close to 5% of the total cancer affected population. A high proportion of this constitutes intra-abdominal tumours. This study was done to study the demographic profile, clinical features and management of intra-abdominal tumours among children. Data of all histopathologically confirmed patients aged < 15 years with various primary intra-abdominal tumours diagnosed from 2009 to 2019 were included in this study. The median age of the patients (n = 50) was 3 years (IQR 1.4, 6). The median age at diagnosis of cancer (n = 23) was 2.5 years (IQR 1, 4). Tumours were more common among males (70%). The most common tumour in this study was Wilm's tumour (17 (34%)). Forty-eight (96%) patients had malignant tumours. Fever was present among the majority (27 (54%)) of the patients. The most common anti-cancer drug used for management was Vincristine, used among 23 patients. Remission was more among infants with Wilm's tumour (P = 0.0221) and among patients with Hodgkin's lymphoma (HL) (P = 0.0444). Default with treatment was more among patients with stage 4 malignancy (P = 0.0186). Recovery following treatment was more among patients with germ cell tumour (P = 0.0082). Reasons for default with treatment in the late stages of malignancies need to be identified in future research studies.
