In the 1st clinical case of bladder cancer, due to concomitant pathology any platinum-containing therapy was impossible. After 9 months of treatment with atezolizumab target lesions decreased by 55 %, and the patient’s condition improved significantly: pain intensity decreased, dysuria frequency decreased, appetite became normal. In the 2 nd clinical case of urothelial cancer, complete response to therapy was achieved after 10 months of treatment. Pain intensity decreased significantly, dysuria was cured. Both patients continue atezolizumab immunotherapy without any adverse events. Therefore, use of up-to-date oncoimmunological medications has entered clinical practice and allows to achieve good therapeutic effect with high treatment safety.</p></abstract><trans-abstract xml:lang="ru"><p>В статье представлены 2 клинических примера применения ингибитора PD-L1 атезолизумаба в терапии уротелиального рака. В 1‑м клиническом случае рака мочевого пузыря при невозможности проведения какой‑либо платиносодержащей химиотерапии ввиду сопутствующей патологии за 9 мес лечения атезолизумабом достигнуто уменьшение целевых очагов на 55 % и отмечено значительное улучшение со стороны общего состояния пациента: снизилась интенсивность боли, уменьшились проявления дизурии, нормализовался аппетит. Во 2‑м клиническом случае уротелиального рака достигнут полный ответ на терапию за 10 мес лечения. Интенсивность болей значительно уменьшилась, дизурические явления купированы. Оба пациента продолжают иммунотерапию атезолизумабом, каких‑либо нежелательных явлений не отмечено. Таким образом, применение современных онкоиммунологических препаратов вошло в клиническую практику и позволяет добиться хорошего терапевтического эффекта при сохранении высокой безопасности лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>immunotherapy</kwd><kwd>atezolizumab</kwd><kwd>urothelial cancer</kwd><kwd>bladder cancer</kwd><kwd>anti PD-L1</kwd><kwd>checkpoint inhibitor</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>иммунотерапия</kwd><kwd>атезолизумаб</kwd><kwd>уротелиальный рак</kwd><kwd>рак мочевого пузыря</kwd><kwd>анти-PD-L1</kwd><kwd>ингибитор контрольных точек</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Choueiri T.K., Ross R.W., Jacobus S. et al.
