Quiz: Introduction to Staging

  1. The concept of describing disease by stage or extent of disease was introduced in 1929 by the League of Nation's World Health Organization.
  2. Staging is a shorthand method for describing disease.
  3. Staging uses a coded format, such as a numerical system with increasing values meaning more involvement or severity, that allows electronic analysis of cases with similar characteristics.
  4. Extent of disease is a detailed description of how far the tumor has spread from the secondary site.
  5. Classification is an orderly arrangement showing relationships among groups, which does not necessarily imply a prognosis.
  6. Only some staging systems consider these elements: the primary tumor site, tumor size, multiplicity (number of tumors), depth of invasion and extension to regional or distant tissues, involvement of regional lymph nodes, and distant metastases.
  7. It is important for the medical practitioner to adequately assess the extent of cancer in order to treat the disease in the most appropriate manner.
  8. Staging can be used to compare treatment results based on common criteria or extent of disease.
