Curcumin and Radiation have synergistic antitumor activity against ARMS xenografts.

<p>(A) The combination of curcumin and radiation had synergistic antitumor activity in the Rh30 xenografts (synergistic index  = −0.940, SE 0.072, 95% confidence interval −1.080, −0.799). In the Rh41 cell line, the combination of curcumin and radiation was also synergistic (synergistic index  = −0.915, SE 0.141, 95% confidence interval (−1.192, −0.638). (B) The antitumor activity when curcumin was given either concomitantly with or prior to radiation.</p>
