Radiation-induced Parotid Gland Atrophy in Patients with Head and Neck Cancer After Carbon-ion Radiotherapy.
BACKGROUND/AIM This study aimed to clarify the relationship between dosimetric factors and parotid gland (PG) atrophy after carbon ion radiotherapy (C-ion RT). PATIENTS AND METHODS Fifty-four patients with head and neck tumours were enrolled and 93 irradiated PGs were analyzed. Thirty and 24 patients were treated with total doses [relative biological effectiveness (RBE)] of 57.6 Gy and 64.0 G...
متن کاملPrognostic analysis of radiation pneumonitis: carbon-ion radiotherapy in patients with locally advanced lung cancer
BACKGROUND Carbon-ion radiotherapy (CIRT) is a promising treatment for locally advanced non-small-cell lung cancer, especially for patients with inoperable lung cancer. Although the incidence of CIRT-induced radiation pneumonitis (RP) ≥ grade 2 ranges from 2.5 to 9.9%, the association between CIRT-induced RP and dosimetric parameters is not clear. Herein, we identified prognostic factors associ...
متن کاملThe Emerging Role of Carbon-Ion Radiotherapy
Carbon-ion radiotherapy (CIRT) has progressed rapidly in technological delivery, indications, and efficacy. Owing to a focused dose distribution in addition to high linear energy transfer and subsequently high relative biological effect, CIRT is uniquely able to target otherwise untreatable hypoxic and radioresistant disease while opening the door for substantially hypofractionated treatment of...
متن کاملCarbon-ion radiotherapy—basic and clinical studies
Radiotherapy using charged and/or high-LET particles has a long history, starting with proton beams. In vitro data clarify that RBE (Relative Biological Effectiveness) increases with LET up to approximately 150 keV/μm for carbon-12 and neon-20 ions. In vivo studies show that tumor control probabilities after single doses of gamma rays shift to higher doses when tumors were irradiated with 5-fra...
متن کاملTreatment Planning for the Carbon Ion Radiotherapy
In the three therapy beam times 2007 about 50 patients were planned and treated with our treatment planning software, TRiP98, and its development version, TRiP98BEAM. In the past, the standard method was to optimize the biological target dose distribution for the contributing partial fields singly. Due to the enormous effort for the computation of biological effects, only a simple, but still su...
