KORTUC, a novel hydrogen peroxide‑based radiosensitizer for the enhancement of brachytherapy in patients with unresectable recurrent uterine cervical cancer.

Kochi Oxydol Radiation Therapy for Unresectable Carcinoma (KORTUC) is a novel radiosensitizer invented by Professor Ogawa at Kochi University (Japan) in 2006. The current study aimed to report the experience of the present authors with the use of KORTUC treatment in combination with interstitial brachytherapy (ISBT), with or without external beam (EB) radiotherapy (RT), in patients with locally recurrent cervical cancer (LRCC), who were likely to have a high risk of poor prognosis. Between April 2012 and January 2020, 14 female patients (15 tumoral lesions) with LRCC underwent KORTUC with ISBT.

Early administration of IL-6RA does not prevent radiation-induced lung injury in mice.

Background: Radiation pneumonia and subsequent radiation lung fibrosis are major dose-limiting complications for patients undergoing thoracic radiotherapy. Interleukin-6 (IL-6) is a pleiotropic cytokine and plays important roles in the regulation of immune response and inflammation. The purpose of this study was to investigate whether anti-IL-6 monoclonal receptor antibody (IL-6RA) could ameliorate radiation-induced lung injury in mice.

Carbon-ion beam irradiation effectively suppresses migration and invasion of human non-small-cell lung cancer cells.

Purpose: Control of cancer metastasis is one of the most important issues in cancer treatment. We previously demonstrated that carbon particle irradiation suppresses the metastatic potential of cancer cells, and many studies have reported that photon irradiation promotes it. The purpose of this study was to investigate the effect of carbon beam on non-small-cell lung cancer (NSCLC) cell aggressiveness and gene expression.

Postoperative radiotherapy for non-small-cell lung cancer: results of the 1999-2001 patterns of care study nationwide process survey in Japan.

To investigate the practice process of postoperative radiation therapy for non-small-cell lung cancer (NSCLC) in Japan. Between April 2002 and March 2004, the Patterns of Care Study conducted an extramural audit survey for 76 of 556 institutions using a stratified two-stage cluster sampling. Data on treatment process of 627 patients with NSCLC who received radiation therapy were collected.
