This is a prospective study on the safety and effectiveness of radiofrequency ablation in patients with desmoid tumors.
In the study group, all patients after radiofrequency ablation of the tumor after 1 month will be evaluated using MRI and CT studies and, if solid components of the tumor are detected, repeated surgical treatment is performed followed by active monitoring after 1 month.
In the absence of a solid component, the effect is estimated by the volume of the necrotic process and monitored in dynamics every 3 months.

GENCONCOR-1 study is translational research aimed to investigate the concordance of the molecular genetic profile of the primary tumor and brain metastases (BM) of colorectal cancer (CRC). The study was conducted by post hoc analysis of pairs of samples of histological material with determination of the mutational status of genes KRAS, NRAS, BRAF, HER2 and MSI.

The goal of this clinical trial is to compare the efficacy of using polypropylene mesh for hernia prevention after stoma closure in patients with colorectal cancer and non-mesh repair. The main question it aims to answer is: can mesh help prevent hernia? Participants will be divided into 2 groups: with and without mesh using. They must be followed up for 2 years after enrollment in the study.
Researchers will compare mesh and non-mesh groups to evaluate the benefits and harms of mesh using in hernia prevention.
