Modern development of high-dose-rate brachytherapy.

Modern development of high-dose-rate brachytherapy. Jpn J Clin Oncol. 2020 Mar 05;: Authors: Itami J Abstract Brachytherapy is an invasive therapy with placement of radiation source into or near the tumor. The difference between planning target volume and clinical target volume is minimal, and the dose out of the tumor reduces rapidly due to the inverse-square law. High-dose-rate brachytherapy enables three-dimensional image guidance, and currently, tumor dose as well as doses of the surrounding normal structures can be evaluated accurately. High-dose-rate brachytherapy is the utmost precision radiation therapy even surpassing carbon ion therapy. Biological disadvantages of high-dose rate have been overcome by the fractional irradiation. High-dose-rate brachytherapy is indispensable in the definitive radiation therapy of cervical cancer. Also in prostate cancer and breast cancer, high-dose-rate brachytherapy plays a significant role. Brachytherapy requires techniques and skills of radiation oncologists at the time of invasive placement of the radiation source into the tumor area. Education of young radiation oncologists is most urgent and important. PMID: 32134450 [PubMed - as supplied by publisher]

CONCLUSION: A decrease of nuclear LCoR expression in line with an increase of dedifferentiation of CIN can be observed. Nuclear LCoR overexpression correlates with CIN II progression indicating a prognostic value of LCoR in cervical intraepithelial neoplasia. Nuclear and cytoplasmic RIP140 expression increases significantly with higher grading of cervical intraepithelial neoplasia underlining its potential role in the development of pre-cancerous lesions. These findings support the relevance of LCoR and RIP140 in the tumorigenesis indicating a possible role of LCoR and RIP140 as targets for novel therapeutic approaches in ...

The objective was to evaluate the health-related lifestyles and cancer-preventive behaviors of medical and nursing students and FM residents in relation to the European Code Against Cancer (ECAC). This was a descriptive, cross-sectional study performed in Spain. Medical and nursing students and FM residents completed a self-administered questionnaire focused on health-related habits and clinical behaviors related to the ECAC. A total of 740 participants completed the questionnaire. About 12.2% (95% CI [9.8 –14.5]) were smokers, and 77.3% (95% CI [74.3–80.3]) sporadically consumed alcohol; 34.2% (95% CI [30.8&nd...

Abstract Photodynamic therapy is the combination of the initial application of a photosensitive chemical on the skin and then using typically a blue filter light of varying spectrums. This treatment protocol has been more useful and functional than other chemical peels and lasers for a variety of conditions. There has been efficacy in antiviral treatments, such as herpetic lesions; malignant cancers of the head and neck; and lung, bladder, and skin cancers. It has been tested for prostate cancers, cervical cancer, colorectal cancer, lung cancer, breast cancer, esophageal cancer, stomach cancer, pancreatic cancer, ...
