Table 2. Statistical significance analyses (p-values) to reveal differences in therapeutic effect between various treatment regimens on the A-375 tumors.

		Treatment groups
Groups	Treatment	1	2	3	4
1	untreated
2	scFvMEL/rGel	0,348
3	scFvMEL/rGel+AlPcS2a	0,036	0,385
4	PDT	0,132	0,493	0,796
5	PCI of scFvMEL/rGel	<0,001	0,001	0,003	0,004

The values are based on paired log rank analyses of the time for the A-375 tumors to reach 800 mm³.
