Variation in accumulated dose of volumetric-modulated arc therapy for pancreatic cancer due to different beam starting phases.

CONCLUSIONS: The beam starting phase affected CTV dosimetric variations of single full-arc VMAT. The use of double full-arc VMAT mitigated this problem. However, variation in the dose delivered to OARs was not dependent on the beam starting phase, even for single full-arc VMAT.
