Abstract
Objective To compare the dosimetric differences of the planning target volume(PTV) and the organs at risk (OAR) for postoperative patients with nasal lymphoma on intensity -modulated radiotherapy(IMRT) and mono -isocenter irradiation. Methods Eight postoperative patients with nasal lymphoma were chosen randomly. The next steps were CT scan, PTV and OAR contouring. The treatment protocols were designed into mono-isocenter irradiation and IMRT by TPS. Finally, the dose distribution and DVH were compared. Results About the conformability of PTV, IMRT showed a significantly superior dose distribution and the differences(P<0.005) have statistical significance. As compared with mono-isocenter irratiation, IMPT could protect some normal tissues, the received dose(P<0.05) of normal tissues were reduced including eyeball, brain stem, pituitary and temporomandibular joint, but with no obvious differences for crystal, optic chiasma and optic nerve(P>0.05). Conclusion In postoperative radiotherapy for nasal lymphoma, IMPT has more dosimetric advantages over mono -isoeenter irradiation technique in radiotherapy.
