Economic burden of resected squamous cell carcinoma of the head and neck in an incident cohort of patients in the UK

Table 3 Total number of deaths and the estimation of survived patients by year

Year	No. of patient followed	No. of deaths identified	No. of patient censored per year¹	Mortality rate per year²	No. of death among censored patients³	No. of survived patient estimated by KMSA⁴	Cumulative survival, all-causes (%)
1 year	11,403	1,706	0	15.0%	0	11,403	-
2 year	9,697	1,044	2,046	10.8%	220	9,697	85.0%
3 year	6,607	520	1,767	7.9%	139	8,433	74.0%
4 year	4,320	274	1,592	6.3%	101	7,774	68.2%
5 year	2,454	-	-	-	-	7,399	64.9%

¹= No. of followed patient - No. of followed patient at next year - No. of death
² = No. of death/No. of followed patient
³ = No. of censored patient * mortality rate per year
⁴ = No. of patient at previous year - No. of death at previous year - No. of death among censored patient at previous year
