Anal cancer survival statistics

Coronavirus (COVID-19)

We have created a central resources hub for Health Professionals which hosts all of our CRUK resources and further materials to help with managing the pandemic. We are updating the information as guidance changes. There is also a page specifically for patients on our about cancer hub.

Survival

Survive anal cancer for 10 or more years, 2013-2017, England

Age

Age that anal cancer survival is highest, 2009-2013, England

 

80.2% of males survive anal cancer for at least one year. This falls to 52.0% surviving for five years or more, as shown by age-standardised net survival for patients diagnosed with anal cancer during 2013-2017 in England.[1] Survival for females at one year is 87.2% and falls to 62.2% surviving for at least five years. Survival for females is higher than for than for males at one year, and higher than for at five years.

Anal cancer survival falls only slightly beyond five years after diagnosis. 52.2% of people are predicted to survive their disease for ten years or more, as shown by age-standardised net survival for patients diagnosed with anal cancer during 2013-2017 in England.[1]

About this data

Data is for: England, 2013 - 2017, ICD-10 C21.

Survival statistics give an overall picture of survival and the survival time experienced by an individual patient may be much higher or lower, depending on specific patient and tumour characteristics.

Five-year survival for anal cancer is highest in the youngest men and women and decreases with increasing age. Five-year net survival in men ranges from 71% in 15-49 year-olds to 46% in 70-89 year-olds for patients diagnosed with anal cancer in England during 2009-2013.[1] In women, five-year survival ranges from 81% to 53% in the same age groups.

Survival for anal cancer is strongly related to stage of the disease at diagnosis.

One-year net survival by stage 

One-year net survival for anal cancer is highest for patients diagnosed at Stage 1, and lowest for those diagnosed at Stage 4, as 2013-2017 data for England show.[1] 99% of patients diagnosed at Stage 1 survived their disease for at least one year, compared to 53% of patients diagnosed at Stage 4.[1]

One year net survival for unknown or missing stage is 78%, while one year survival for unstageable cancer is 77%. Lack of staging information may in some cases reflect advanced stage at diagnosis as very unwell patients may not undergo staging tests if the invasiveness of the testing outweighs the potential benefit of obtaining stage information. Incomplete staging assessment may also be associated with socio-demographic and clinical characteristics of the patient [2]. Stage completeness for anal cancer was 83% in 2013-2017 [1].

For patients diagnosed at Stage 3, one-year net survival is significantly higher for females than for males, with an absolute survival difference of 11 percentage points. One-year net survival is also higher for females at Stage 2 (difference of 6 percentage points).[1]

Net survival can be greater than 100% because it accounts for background mortality. Net survival greater than 100% indicates that patients in this group have a better chance of surviving one year after diagnosis compared with the general population.
