Lung cancer still holds the leading position in terms of morbidity and mortality, both among men and women. The five-year survival rate for lung cancer is one of the lowest among cancers and varies from 5% to 15% for different countries. The study of new directions in the treatment of this nosology is an extremely urgent problem at the present time. The most common histological variant is non-small cell lung cancer. The presence of driver mutations (EGFR, ALK, ROS1) makes it possible to use targeted therapy in these patients. However, in the absence of driver mutations, the treatment of disseminated non-small cell lung cancer is still based on chemotherapy, which has a low efficiency, making up only about 30% in the first line of treatment. A promising approach to the treatment of this group of patients is the use of immunotherapy, in particular anti-PD-1 and anti-PD-L1 checkpoint-inhibitors. In large randomized international clinical trials, pembrolizumab and atezolizumab were shown to be effective in the first line of treatment, and nivolumab in the second line of treatment. Moreover, according to meta-analyses on the effectiveness and safety of immunotherapy, PD-L1 inhibitors (atezolizumab, avelumab, and durvalumab) have a lower toxicity profile compared to PD-1 inhibitors (pembrolizumab and nivolumab). This article presents a clinical observation of effective treatment of a patient with disseminated non-squamous non-small cell lung cancer with a combination of atezolizumab with bevacizumab and chemotherapy. The partial effect of treatment achieved in this patient is maintained for 3 years without the unacceptable toxicity.
