The authors compare dose distributions in local irradiation of prostatic cancer using moving methods on distant gamma-units while taking and not taking into account individual structure of body section and bone structures. They propose problems of choice of optimum conditions of gamma-beam therapy in localized prostatic cancer and their solution. Optimum irradiation designs have been found preferable. When individual dose field calculations are impossible to implement, rotational 360 degree irradiation with correction for 8% and absorption in the table of a gamma-therapeutic unit is recommended.

Background: Preoperative neoadjuvant chemoradiotherapy (nCRT) is considered to be the standard treatment strategy for locally advanced rectal cancer (LARC); however, the risk of adverse events and postoperative recurrence remains significant. This study aimed to evaluate the non-inferiority of neoadjuvant chemotherapy (nCT) compared with nCRT in patients with LARC and to assess the possibility of eliminating radiotherapy on the basis of guaranteed efficacy.
Materials And Methods: We searched the PubMed, Embase, and Cochrane Library databases to identify randomized controlled trials (RCTs) comparing the efficacy of nCRT and nCT for LARC.

Objectives: Cutaneous adnexal carcinomas (CACs) are rare skin cancers with no established treatment guidelines. Given the limited data, this study aims to explore the characteristics and outcomes of patients with CAC treated with radiation therapy (RT).
Methods: Patients diagnosed with CAC between 2000 and 2020 who received RT were included.

Purpose: Therapeutic options for patients with brain metastases (BM) increase. While these lead to considerable survival effects in subgroups, there is limited knowledge about characteristics, prognosticators and treatment effects in patients with BM and short survival.
Methods: Patients with a survival time of ≤ 6 months (short-term survivors, STS), diagnosed with BM between 2009-2021 at a large tertiary cancer center were analysed.
Resistance to radiotherapy remains a critical barrier in treating colorectal cancer (CRC), particularly in cases of locally advanced rectal cancer (LARC). To identify key kinases involved in CRC radioresistance, we employed a kinase-targeted CRISPR-Cas9 library screen. This approach aimed to identify potential kinase inhibitors as radiosensitizers.
