Analyses of tumor growth, invasion, and metastasis

Treatment	Time (d) to reach 4 times the treatment volume (mean ± SEM)	Evidence of local invasion or lymph node metastases	No. of lung metastases (mean ± SEM)
Control diet, no radiation	12.7 ± 0.8	none	29.7 ± 7.2d
Fenbendazole diet, no radiation	12.1 ± 0.6a	none	29.7 ± 4.3d
Control diet, tumor irradiation	17.5 ± 1.3b	none	28.6 ± 3.9d
Fenbendazole diet, tumor irradiation	20.4 ± 0.9bc	none	24.3 ± 9.1d

The significance of differences between groups was assessed by using Mann–Whitney U tests.

^aNot significantly different (P = 0.32) from value for tumors in unirradiated mice on the control diet.

^bSignificantly different (P < 0.05) from value for unirradiated tumors.

^cNot significantly different (P = 0.12) from value for tumors in irradiated mice on the control diet.

^dNone of the differences between groups were statistically significant (P > 0.05 for all comparisons).
