Carbon-ion radiotherapy (CIRT) holds promise to treat inoperable locally-advanced non-small cell lung carcinoma (NSCLC), a disease poorly controlled by standard chemoradiotherapy using X-rays. Since CIRT is an extremely limited medical resource, selection of NSCLC patients likely to benefit from it is important; however, biological predictors of response to CIRT are ill-defined. The present stu...
Nowadays, head and neck squamous cell carcinoma (HNSCC) treatment failure is mostly explained by locoregional progression or intrinsic radioresistance. Radiotherapy (RT) has recently evolved with the emergence of heavy ion radiations or new fractionation schemes of photon therapy, which modify the dose rate of treatment delivery. The aim of the present study was then to evaluate the in vitro in...
The immune system plays a complementary role in the cytotoxic activity of radiotherapy. Here, we examined changes in immune cell subsets after heavy ion therapy for prostate cancer. The lymphocyte counts were compared with acute radiotherapy-related toxicity, defined according to the Common Terminology Criteria for Adverse Events, and short-term local efficacy, defined based on prostate-specifi...
BACKGROUND Patients with Echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase (ALK) positive lung cancer are sensitive to ALK-kinase inhibitors. TAE684 is a potent second generation ALK inhibitor that overcomes Crizotinib resistance. Radiotherapy is an integral therapeutic component of locally advanced lung cancer. Therefore, we sought to investigate the effects of...
Background/Aim: We aimed to evaluate the clinical outcomes of oligometastatic colorectal cancer in liver and lung treated with carbon-ion radiotherapy (C-ion RT). Patients Methods: Nineteen consecutive patients or who received C-ion RT were analyzed. The doses 60.0 Gy [relative biological effectiveness (RBE)] 4 fractions, (RBE) 12 64.8 (BRE) fractions. Results: median follow-up duration was 19 ...
Self-developing radiochromic film is widely used in radiotherapy QA procedures. To compensate for typical inhomogeneities, the triple channel analysis method commonly photon-irradiated film. We investigated applicability of this GafchromicTMEBT3 (Ashland) irradiated with a clinically carbon-ion beam. Calibration curves were taken from EBT3 specimens monoenergetic beams different doses. Measurem...
