Summary
The National Wilms Tumor Study improved pediatric kidney cancer survival to 90% by tailoring treatments. This approach reduces harmful therapies, ensuring healthier long-term outcomes for childhood cancer survivors.
Area of Science:
- Pediatric Oncology
- Clinical Research
- Cancer Epidemiology
Background:
- The National Wilms Tumor Study (NWTS) was North America's first pediatric intergroup clinical research unit.
- It aggregated data from multiple childhood cancer cooperative study groups, enabling robust research on malignant kidney tumors in children.
Purpose of the Study:
- To investigate the nature and clinical characteristics of childhood kidney malignant tumors.
- To conduct randomized trials comparing treatment regimens for Wilms tumor.
- To stratify patients based on risk criteria for tailored therapy.
Main Methods:
- Collected data from approximately 350 pediatric patients annually.
- Implemented risk-stratified patient stratification.
- Conducted randomized comparative treatment trials.
Main Results:
- Achieved a two-year survival rate of 90% for pediatric kidney cancer.
- Significantly reduced the use of routine post-operative radiation therapy.
- Decreased the administration of cardiotoxic doxorubicin, reserving it for advanced cases.
Conclusions:
- Treatment intensity for Wilms tumor can be modulated based on risk criteria, improving survival rates.
- Minimizing exposure to toxic therapies like radiation and doxorubicin is crucial for preventing long-term complications in childhood cancer survivors.
- The NWTS demonstrated a successful model for pediatric cancer research, prioritizing both cure and quality of life.

Longitudinal Research
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
Treatment Resistent Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
