NK Cell Activity and IFN-gamma Production by PBMCs at Diagnosis (P1) and After Completion of Cancer Treatment (P2)

Immunological Measure	Lytic Units or ng per ml
	P1	P2	t	df	p
	(mean ± SEM) [95% CI]
NKCA	43.6 ± 2.6	98.9 ±5.3	−10.809	26	<0.001
	[44.7 – 65.8]
IFN-gamma	4.5 ± 0.4	12.7± 0.5	−10.556	25	<0.001
	[6.6 – 9.8]

NKCA, natural killer cell activity as lytic units at 20% lysis, N= 28.

IFN-gamma, as ng/ml, N=27.

P1= after surgery but before radiation therapy, P2 = 2 months after the completion of radiation therapy.
