Study Notes
Childhood Cancers Overview
- Cancer is the second leading cause of death in children aged 1 to 14, following accidents.
- Approximately 300,000 children (ages 0-19) are diagnosed with cancer annually worldwide.
- Incidence rate for childhood cancer is approximately 15-16 cases per 100,000 children each year, highlighting its rarity.
- In high-income countries, over 80% of childhood cancer cases lead to cure; in low- and middle-income countries (LMICs), only about 20% are cured.
Differences Between Childhood and Adult Cancers
- Childhood cancers primarily affect tissues, while adult cancers commonly involve organs.
- Childhood cancers are predominantly non-epithelial and mesenchymal, contrasting with adults, where carcinomas are most common.
- There is a short latency period for childhood cancers, while adult cancers exhibit a long latency period.
- Genetic factors play a substantial role in childhood cancers, whereas adult cancers are more influenced by environmental and lifestyle factors.
- Limited prevention strategies exist for childhood cancers, while approximately 80% of adult cancers are preventable.
Detection and Treatment
- Many childhood cancers are discovered accidentally, unlike adult cancers, which often benefit from screening leading to early detection.
- A significant proportion (80%) of childhood cancers have already metastasized at diagnosis, while adult cancers are typically localized or regional.
- Treatment for childhood cancers tends to be responsive, demonstrating a higher success rate compared to adult cancers, which are often less responsive.
- Long-term consequences arising from treatments are more prominent in childhood cancer survivors versus adult cancer survivors, who often face fewer long-term health issues.
- Cure rates for childhood cancers exceed 70-80%, reflecting advancements in pediatric oncology treatment protocols.
