Carbon‐ion radiotherapy versus radiofrequency ablation as initial treatment for early‐stage hepatocellular carcinoma

Hepatology Research, 2022
Carbon‐ion radiotherapy (C‐ion RT) has shown potential as a curative treatment for patients with hepatocellular carcinoma (HCC). However, no reports have compared the effectiveness of C‐ion RT and radiofrequency ablation (RFA).

Carbon Ion Radiotherapy for Unresectable Retroperitoneal Sarcomas

International Journal of Radiation Oncology*Biology*Physics, 2009
To evaluate the applicability of carbon ion radiotherapy (CIRT) for unresectable retroperitoneal sarcomas with regard to normal tissue morbidity and local tumor control.From May 1997 to February 2006, 24 patients (17 male and 7 female) with unresectable retroperitoneal sarcoma received CIRT. Age ranged from 16 to 77 years (median, 48.6 years).

Effects of dose and dose-averaged linear energy transfer on pelvic insufficiency fractures after carbon-ion radiotherapy for uterine carcinoma.

Radiotherapy and Oncology, 2022
BACKGROUND AND PURPOSE The correlation between dose-averaged linear energy transfer (LETd) and its therapeutic or adverse effects, especially in carbon-ion radiotherapy (CIRT), remains controversial.

Carbon ion radiotherapy of skull base chondrosarcomas

International Journal of Radiation Oncology*Biology*Physics, 2007
To evaluate the effectiveness and toxicity of carbon ion radiotherapy in chondrosarcomas of the skull base.Between November 1998 and September 2005, 54 patients with low-grade and intermediate-grade chondrosarcomas of the skull base have been treated with carbon ion radiation therapy (RT) using the raster scan technique at the Gesellschaft für ...

Workflow of Carbon-Ion Radiotherapy

2013
The carbon-ion radiotherapy system consists of oncology information system (OIS), radiotherapy treatment planning system (RTPS), and beam delivery system (BDS), which is similar to the standard radiotherapy system. However, there are some differences, such as a big accelerator system, no gantry system (except HIT), and an efficient workflow system. The

Treatment Planning for Carbon Ion Radiotherapy

2001
One of the main objectives in radiotherapy is the conformai delivery of the prescribed dose to the target volume, whereas the surrounding healthy tissue and critical structures should be spared as much as possible. In comparison with conventional photon beams, therapeutic ion beams in general offer the advantage of a depth dose distribution with a ...
