Anti-tumor immunity modulates the local effects of radiation therapy. High mobility group box 1 (HMGB1) plays a pivotal role in activating antigen-specific T-cell responses. Here, we examined relationship between linear energy transfer (LET) and HMGB1 release. We assessed proportions KYSE-70, HeLa SiHa cells surviving after carbon-ion (C-ion) beam irradiation with different LET values, using clonogenic assay. The D10, dose at which 10% survived, was calculated linear–quadratic model. levels...

378 Background: The potential of carbon ion radiation therapy (CIRT) as a curative treatment for localized prostate cancer (PCa) has garnered attention due to its characteristic dose distribution. There is no data on long-term urinary function or changes in volume patients after CIRT. We prospectively collected and analyzed over five years investigate the outcomes related PCa treated with Methods: This study included classified T1-T3N0M0 according TNM staging system. A total 309 who...

This study aimed to assess the long-term outcomes of radiotherapy in patients with localized gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Twenty-seven Stage I MALT lymphoma were treated from 1999 2010. The median age was 65 years (range: 31-84). Fifteen Helicobacter pylori-negative. Thirteen definitive alone. other 14 who had refractory or residual disease following a prior treatment received salvage radiotherapy. dose 30 Gy 20 fractions 30-39.5 Gy). follow-up period 121 months...

Recently, the clinical outcome of prostate cancer treated by hypofractionated radiation therapy has been reported. However, there are few reports from Japan. In Hidaka Hospital, intensity-modulated radiotherapy (HIMRT) for was initiated in 2007. The purpose this study is to analyze long-term outcome.Ninety-two patients with localized HIMRT at Hospital between 2007 and 2009 were retrospectively analyzed. delivered using TomoTherapy. prescription dose 66 Gy 95% PTV 22 fractions performed 3...

This study aimed to evaluate clinical outcomes and the toxicity of intensity-modulated radiation therapy with simultaneous integrated boost (SIB-IMRT) combined androgen-deprivation for clinically node-positive (cN1) prostate cancer. We retrospectively analyzed 97 patients cN1 cancer who received SIB-IMRT between June 2008 October 2017 at our hospital. The prescribed dosages delivered seminal vesicle, elective node area, residual lymph nodes were 69, 54, 60 Gy in 30 fractions, respectively....

Abstract Background The quality of life patients is an important consideration when selecting treatments for localized prostate cancer (PCa). We retrospectively compared sexual function after robot-assisted radical prostatectomy (RARP) and carbon-ion radiotherapy (CIRT) using propensity score matching. Methods In total, 127 Japanese PCa treated with RARP 190 CIRT monotherapy were evaluated. evaluated the Expanded Prostate Cancer Index Composite (EPIC) before treatment 12 24 months treatment....
