Abstract: (458 Views)
Background: Prostate cancer is one of the most common cancers in the world, which is associated with a high prevalence, especially in the elderly male population. Treatment options for non-metastatic prostate cancer usually include active surveillance, radiotherapy and surgery, so the aim of the present study is a systematic review of brachytherapy in the treatment of prostate cancer.
Methods: The study conducted is a systematic review article in which a review of the treatment of prostate cancer with brachytherapy has been done. The information used is taken from articles published in Persian and English in Google scholar, SID and PubMed databases from 2000 to 2022. The selected keywords in this article included Brachy therapy, Prostate cancer, Radio therapy, Prostate neoplasms, High dose rate, Low dose rate and External beam radio therapy. Selection of studies was done according to PRISMA guidelines.

Results: Brachytherapy can be classified into 2 types of permanent implantation and temporary implantation based on the length of the treatment period. In permanent brachytherapy implants for prostate cancer, iodine (125I) or palladium (103Pd) are used as radioactive sources for low dose rate cases and for high dose rate brachytherapy. Iridium (192Ir) is used. Brachytherapy is usually used in two ways, either as a monotherapy in which LDR and HDR are used to treat some low-risk patients, or as a booster treatment after other treatments such as EBRT, which here may be part of the treatment process before, after, or during treatment. In contrast to brachytherapy alone, brachytherapy plus EBRT is an appropriate approach in patients with intermediate-risk and high-risk disease. In high-risk patients, the combined use of EBRT and HDR-BT can lead to better results than EBRT alone. Brachytherapy treatment is not suitable for every disease.
Conclusion: One of the main advantages of this treatment method is the ability to administer a high dose of radiation while minimizing radiation exposure to adjacent healthy organs. Since optimal dose distribution occurs in the treatment, quality treatment can be ensured. The results obtained from both forms of brachytherapy are generally suitable and comparable to other treatment methods with fewer side effects. |
