Clinical trials

Sentinel lymph node biopsy (SLNB) is the standard of axillary lymph node surgical staging in patients with early breast cancer. The main goal of the study is to abandon axillary surgery in patients over 59 years old with early, luminal A, clinical lymph node negative breast cancer.

This is a prospective, single-center, non-randomized phase II study. Patients with germ cell tumors of gonadal and extragonadal localization who have progressed after prior platinum-containing first-line chemotherapy will receive high-dose chemotherapy with TI (2 cycles) folollowed by high dose CE chemotherapy with autologous stem cell transplantation (3 cycles). The primary endpoint of the study is to evaluate the efficacy high-dose chemotherapy as second-line drug therapy for patients with advanced germ cell tumors.

Data from 40 patients are planned to be included in the study to randomize approximately 10 patients. This study involves patients with advanced/metastatic GD2-positive rhabdomyosarcoma after progression on 1st line of chemotherapy, advanced/metastatic GD2-positive Ewing sarcoma after progression on 1st line of chemotherapy and advanced/metastatic GD2-positive osteosarcoma after progression on 1st line of chemotherapy. All patients will receive therapy until disease progression (a total of 6 courses of immunotherapy). The primary objective of the study is to determine the efficacy and safety of dinutuximab beta with investigator's choice of chemotherapy.

The investigators will collect biosamples of patient blood and tumour tissue for further immunological analysis of blood cell subpopulations, immunosupressive factors concentration, HLA expression an lymphocytes and tumour tissue, and and cancer testis antigenes expression on tumour cells, as well as clinical data on patient's stage, therapy, response and demographics. Possible prognostic and predictive dynamic biomarkers will be discovered for individualisation of treatment strategies

There is a huge variety of nucleotide substitutions that activate RAS. The search for new "universal" drugs for the RAS pathway that either interfere with RAS upregulation upstream in the signaling pathway or offset the consequences of RAS activation is important for improving therapeutic outcomes for patients with refractory malignancies. The use of leflunomide or the combination of MEK inhibitor + hydroxychloroquine ± bevacizumab is promising for patients with mutations in RAS cascade genes who have failed all existing treatment standards.

The main goal of the study is to abandon breast surgery in patients with breast cancer with a clinical complete response (cCR) after neoadjuvant systemic therapy and confirmed pCR using Vacuum-assisted biopsy (VAB) and sentinel lymph node biopsy (SLNB). Evidence of the high diagnostic accuracy (sensitivity and specificity) of vacuum aspiration biopsy in determining pCR in patients with clinical complete response after neoadjuvant systemic therapy will allow abandoning breast surgery in favor of radiation therapy alone, improving the quality of life of these patients.

Combined treatment of soft tissue sarcoma includes 3 steps: 1. step - preoperative stereotactic radiation therapy in hypofractionation mode 2. step - operation 3. step - postoperative conformal radiation therapy in normofractionation mode
