Radiosensitization Effect of Nedaplatin on Nasopharyngeal Carcinoma Cells in Different Status of Epstein-Barr Virus Infection

Table 2

Parameters of NPC cells in single-hit multitarget model under different conditions.

Parameters	CNE-2			C666
	RT	RT + NDP1	RT + NDP2	RT	RT + NDP1	RT + NDP2
𝐷0	2.20	1.45	1.01	2.55	1.75	1.21
𝐷𝑞	0.55	0.03	0.01	0.84	0.43	0.17
SF2	0.47	0.26	0.14	0.53	0.33	0.20
SER	—	1.52	2.18	—	1.46	2.11

𝐷₀: lethal radiation dose; 𝐷_𝑞: quasi-threshold dose; SF₂: fraction of cells surviving after 2 Gy radiation; SER: radiosensitization ratio (sensitization enhancement ratio), calculated as 𝐷₀ for the control group divided by 𝐷₀ for the treatment group.
