Cancer patterns and association with mortality and renal outcomes in non-dialysis dependent chronic kidney disease: a matched cohort study

Table 6 Comparison of outcomes between the groups split based on date of cancer occurrence prior to recruitment in matched sample

Outcome	No cancer (337)	Concurrent history of cancer < 1 year Group A (58)	Cancer history > 1 year and < 5 years Group B (119)	Cancer history > 5 years Group C (160)	p-Value Group A vs Group C
Death	129 (38.3%)	33 (56.9%)	67 (56.3%)	66 (41.2%)	0.04
Cancer death	6/52 (11.5%)	6/17 (35.3%)	8/30 (26.7%)	5/29 (17.2%)	0.16
CVD death	13/52 (25%)	2/17 (11.8%)	9/30 (30%)	10/29 (34.5%)	0.09
ESRD	87 (25.8%)	19 (32.8%)	24 (20.1%)	44 (27.5%)	0.45
RRT	65 (19.3%)	7 (12.1%)	14 (11.8%)	37 (23.1%)	0.07
Transplants	7/65 (10.8%)	0/7	1/14 (7.1%)	2/37 (7.4%)	> 0.05^a

Cause of death data was available only in 52/129 of the no cancer group, 17/33 of group A, 30/67 of group B and 29/66 of group C. CVD cardiovascular disease, ESRD end-stage renal disease, RRT renal replacement therapy. p-Value by Chi-square test, a-p-Value by Fisher Exact test. Statistically significant p-values are displayed in bold (i.e. p < 0.05)
