Definition: | Degree of spread of cancer is a measure of the progression/extent of cancer at a particular point in time. |
Context: | This information is collected for the purpose of: - determining what proportion of cancers are localised to the site of the primary cancer at the time of diagnosis. - indicating the extent of disease at the time of diagnosis. - for previously diagnosed cancers, the degree of spread may be measured at each patient episode to track the progression of the cancer. - assessing how early in its course the cancer was diagnosed (used to assess impact of early diagnosis measure). - estimating severity by degree of spread (used for comparing survival after adjusting for degree of spread). |
