Insights

Childhood cancer survivors face increased risks of hospitalization and death from various causes, including cancer, infection, and injury. Long-term monitoring is crucial for these survivors to manage late effects and improve outcomes.

Area of Science:

  • Oncology
  • Epidemiology
  • Public Health

Background:

  • Childhood cancer survival rates have improved significantly.
  • Long-term health outcomes for childhood cancer survivors require ongoing investigation.
  • Population-based data offers a valuable resource for studying late effects in large survivor cohorts.

Purpose of the Study:

  • To examine serious long-term health outcomes in childhood cancer survivors.
  • To compare hospitalization and mortality rates between survivors and a matched comparison group.
  • To identify specific causes of hospitalization and death among survivors based on cancer type and patient characteristics.

Main Methods:

  • Utilized Washington State population-based data from 1982-2014.
  • Included all childhood cancer survivors diagnosed before age 20 who survived for at least 5 years (n=3,152).
  • Compared outcomes with a sample of children from the same birth cohorts, with follow-up up to 27 years.

Main Results:

  • During a median 9-year follow-up, 12% of survivors were hospitalized and 4% died.
  • Highest risks per 1,000 person-years were for cancer, infection, injuries, and endocrine/metabolic disorders.
  • Survivors had significantly increased hazard ratios for hospitalization (2.7) and all-cause death (14.7), with notable increases for cancer, hematological, nervous system, and circulatory outcomes.

Conclusions:

  • Childhood cancer survivors exhibit elevated risks for long-term conditions, including fractures and injuries.
  • Findings confirm increased risks for other selected health conditions.
  • Pooling multi-state population-based data is recommended to enhance the evaluation of outcomes for rare cancer types and underrepresented racial/ethnic groups.

Hospitals-II

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Hospitals-I

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

What is Population Genetics?01:25

What is Population Genetics?

A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Conservation of Small Populations02:04

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.
