Objective:
This study evaluates the burden of pediatric malignant solid tumors (PMST) in southeastern Nigeria.
Methods:
Analysis of 174 cases of PMST managed at the University of Nigeria Teaching Hospital Enugu, from January 2002 to November 2007.
Results:
PMST comprised 2.8% of pediatric admissions. Tumors encountered were lymphomas 77 (44.3%), Wilms' tumor 35 (20.1%), sarcomas 20 (11.5%), neuroblastoma 15 (8.6%), retinoblastoma 14 (8.0%), teratomas 8 (4.6%) and hepatoma 5 (2.9%). Mean time for diagnosis was 3.3 +/- 2.4 months. Advanced disease occurred in 135 (77.6%), while 39 (22.4%) had early disease. Only 166 (95.4%) commenced planned therapy, with 67 (40.4%) lost to follow-up. Of 99 children available for evaluation, 43 died (11 treatment related and 32 from relapse). Overall, 56 (56.6%) were alive after a mean follow-up of 20.7 +/- 10.5 months.
Conclusion:
PMST are enormous challenge in our setting. Delayed presentation, poor treatment compliance and healthcare funding have to be addressed to improve outcomes.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
