The use of targeted therapies and selection of the optimal treatment sequence in heterogeneous population of patients with metastatic kidney cancer. Results of retrospective study

Renal cancer is one of the most rapidly spreading diseases in the world. As you know, a few years ago, overall survival of patients with metastatic renal cell carcinoma (mRCC) was disappointing: median overall survival rarely exceeded 13 months, while 5-year survival rate was less than 5 %. Immunotherapy with interferon-alpha and interleukins demonstrated low efficiency. Appearance of targeted therapies for the treatment of mRCC significantly increased the duration and quality of life of patients receiving drug treatment. Nowadays due to this methodology and guided by the results of randomized clinical trials we can choose an optimal sequence of therapy and control the disease in three consecutive lines for about 30 months. In this article we would like to share an experience of the use of targeted therapies in the Saint Petersburg City Clinical Oncology Dispensary in patients with clear-cell mRCC.
