WitrynaIn the NPC cohort, the lungs were the organs that were most sensitive to radiation-induced cancer. Conclusion: VMAT afforded superior results in terms of organ-at-risk-sparing compared with IMRT. Most OED-based second cancer risks for various organs were similar when VMAT and IMRT were employed, but the risks for the oral cavity … jbl monitors lsr308
