Radiation therapy has been progressively improved in order to maintain a satisfactory tumour response, while reducing toxicity. We will review the incidence of radiodermatitis and fibrosis according to the various radiation and fractionation techniques. We will then focus on the various methods used to manage, prevent, and quantify this toxicity.
More than 1753 articles were identified using the various search terms. We selected 53 articles to answer the questions addressed in this study according to criteria set in advance.
The literature reports lower acute toxicity with IMRT compared to 3DCRT, but no significant differences in terms of late toxicities. Partial breast irradiation appears to be less effective in terms of local control with a higher rate of late toxicity. Intra operative radiation therapy appears to provide good results in terms of both local control and late toxicity. The hypofractionation has equivalent efficacy and safety to the normofractionated regimen, but with lower rates of radiodermatitis and fibrosis. The adddition of a boost, particularly a sequential boost, increases the risk of fibrosis and radiodermatitis during treatment.
The development of IMRT has significantly reduced acute toxicity and has improved tolerability during treatment. Modified fractionation has reduced treatment time, as well as adverse effects.
为了在降低毒性的同时保持令人满意的肿瘤反应,放射治疗技术不断进步。我们将根据不同的放射和分割技术回顾放射性皮炎和纤维化的发生率。然后我们将重点关注用于管理、预防和量化这种毒性的各种方法。
使用各种检索词识别出1753篇以上的文章。根据预先设定的标准,我们选择了53篇文章来回答本研究中提出的问题。
文献报道,与三维适形放疗相比,调强放疗的急性毒性较低,但晚期毒性方面无显著差异。部分乳腺照射在局部控制方面似乎效果较差,晚期毒性发生率较高。术中放疗在局部控制和晚期毒性方面似乎都能取得良好效果。大分割放疗与常规分割方案具有同等的疗效和安全性,但放射性皮炎和纤维化的发生率较低。增加一次增量照射,尤其是序贯增量照射,会增加治疗期间纤维化和放射性皮炎的风险。
调强放疗的发展显著降低了急性毒性,并提高了治疗期间的耐受性。改良分割放疗缩短了治疗时间,同时减少了不良反应。
