Carbon-ion radiotherapy (CIRT) for prostate cancer was initiated at Kanagawa Cancer Center in 2015. The present study analyzed the preliminary clinical outcomes of CIRT for prostate cancer.
Article
Carbon-ion radiotherapy (C-ion RT) provides better dose distribution in cancer treatment compared to photons. Additionally, carbon-ion beams provide a higher biological effectiveness, and thus a higher tumor c...
Article
Lung cancer is frequently complicated by interstitial lung disease (ILD). Treatment protocols for lung cancer patients with ILD have not been established; surgery, chemotherapy, and radiotherapy can all cause ...
Article
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 pn...

Osteosarcoma is a radioresistant tumor. There have been few reports on the effectiveness of radiotherapy for unresectable osteosarcoma using photon (X-ray) beams. Carbon ion beams have a unique physical advant...
Article
The standard treatment for metastatic liver tumor from breast cancer is systemic medical treatment, and there is controversy regarding the value of local treatment. However, there are some exceptional cases th...
Article
To moving lung tumors, we applied a respiratory-gated strategy to carbon-ion pencil beam scanning with multiple phase-controlled rescanning (PCR). In this simulation study, we quantitatively evaluated dose dis...
Article
This study aims to assess the usefulness of monitoring serum α-fetoprotein (AFP) levels for predicting recurrence patterns in patients with hepatocellular carcinoma (HCC) treated with carbon-ion radiotherapy.
Article
Osteoradionecrosis (ORN) is a critical complication after carbon ion (C-ion) or photon radiotherapy (RT) for head and neck tumors. However, the risk factors for ORN after C-ion RT remain unclear. Therefore, th...
Article
The purpose of this study was to evaluate the efficacy and feasibility of carbon ion radiotherapy (CIRT) for oligo-recurrent lung tumors from colorectal cancer (CRC).

Article
We evaluated whether or not PET or PET/CT using L-methyl-[11C]-methionine (MET) can allow for the early prediction of local recurrence and metastasis, as well as the prognosis (disease-specific survival), in p...
Article
Recurrences of cervical cancer after definitive radiotherapy often occur at common iliac or para-aortic lymph nodes as marginal lymph node recurrences. Patients with these recurrences have a chance of long-ter...
Article
Our aim was to describe the incidence and sites of metastatic chordomas and show their characteristic computed tomography (CT) and magnetic resonance (MR) findings.
Chapter
The National Institute of Radiological Sciences in Chiba, Japan (NIRS) has the highest number of patients with lung cancer treated with carbon ion beams in the world. This report describes the techniques and c...
Chapter
In 1994, carbon ion radiotherapy (CIRT) was initiated at the National Institute of Radiological Sciences (NIRS) in Japan using the Heavy Ion Medical Accelerator in Chiba (HIMAC), which was the world’s first he...
Article
Chordoma, a rare cancer, is usually treated with surgery and/or radiation. However, very limited characterizations of chordoma cells are available due to a minimal availability (only two lines validated by now...

Basal cell adenocarcinoma accounts for approximately 1.6% of all salivary gland neoplasms. In this report, we describe our experiences of treatment for BCAC with carbon ion radiotherapy in our institution.
