Real-time energy measurement of clinical carbon ion beams using a cross-correlation time-of-flight method with parallel-plate chambers. [PDF]

Med Phys
Abstract Background In carbon‐ion radiotherapy (CIRT), the beam energy determines both the particle range and the overall dosimetric quality. Range‐verification QA devices such as Zebra and Giraffe, which are based on multilayer ionization chambers (MLICs), can verify the range but only under dedicated QA conditions, leaving any energy deviations ...

Dosimetric rationale and preliminary experience in proton plus carbon-ion radiotherapy for esophageal carcinoma: a retrospective analysis

Radiation Oncology, 2023
Background Concurrent chemoradiotherapy has been standard of care for unresectable esophageal carcinoma. There were no reports on proton radiotherapy (PRT) plus carbon-ion radiotherapy (CIRT) with pencil beam scanning (PBS) for esophageal carcinoma. This

Carbon ion radiotherapy for prostate cancer with bladder invasion

BMC Urology, 2021
Background The optimal management of clinical T4 (cT4) prostate cancer (PC) is still uncertain. At our institution, carbon ion radiotherapy (CIRT) for nonmetastatic PC, including tumors invading the bladder, has been performed since 2010.

The Majority of United States Citizens With Cancer do not Have Access to Carbon Ion Radiotherapy

Frontiers in Oncology, 2022
As of December 31, 2020, there were 12 facilities located in Asia and Europe which were treating cancer patients with carbon ion radiotherapy (CIRT). Between June 1994 and December 2020, 37,548 patients were treated with CIRT worldwide.

Application of intrahepatic fiducial markers in carbon ion radiotherapy for pancreatic cancer-Achieving higher precision treatment. [PDF]

J Appl Clin Med Phys
Abstract Background Carbon‐ion radiotherapy (CIRT) delivers highly conformal tumor doses while sparing surrounding organs‐at‐risk (OAR). However, density variations along the beam path and interfractional target motion can reduce target coverage and expose OAR to high doses.

Comparison of clinical outcomes between carbon ion radiotherapy and X-ray radiotherapy for reirradiation in locoregional recurrence of rectal cancer

Scientific Reports, 2022
Carbon ion radiotherapy (CIRT) has garnered interest for the treatment of locoregional rectal cancer recurrence. No study has compared CIRT and X-ray radiotherapy (XRT) for reirradiation (reRT) in such cases.

Carbon ion radiotherapy triggers immunogenic cell death and sensitizes melanoma to anti-PD-1 therapy in mice

OncoImmunology, 2022
Carbon ion radiotherapy (CIRT) is an emerging type of radiotherapy for the treatment of solid tumors. In recent years, evidence accumulated that CIRT improves the therapeutic outcome in patients with otherwise poor response to immune checkpoint blockade.
