The survival time for a cancer patient is defined as the time elapsed between diagnosis and death The following table details information on the incidence of cervical cancer (ICD-10 C53) in Northern Ireland for the last period for which data was available.
Diagnosis Period 1996-99 1-Year (95 % CI) 85.9 % (81.4, 89.4) 5-Year (95% CI) 71.9 % (65.9, 77.0) Source: NI Cancer Registry.
Survival from cervical cancer is highly dependent upon the stage at which the disease is diagnosed. The five-year survival rate for stage I cervical cancer was 82 per cent. for patients diagnosed between 1996 and 1999, compared to 2 per cent. for Stage IV disease.
This information has been provided by the Northern Ireland Cancer Registry and is the most up to date currently available.
Notes:
1. Figures in brackets represent the 95 per cent. confidence interval, which is the range of values within which there is a 95 per cent. probability of finding the true value for the survival rate.
2. The estimation of patient survival is complicated by the fact that some patients die of causes unrelated to the cancer of interest. To allow for the deaths due to other diseases, survival is expressed as relative survival rate (RSR). Relative survival is the ratio of the observed survival divided by the survival that the patients would have experienced if they had the same probability of dying as the general population having the same age and sex.
