Rechallenge of camrelizumab in non-small-cell lung cancer patients treated previously with camrelizumab and microwave ablation. Journal of Cancer Research and Therapeutics. 2020 Sep; 16(5): 1191-11950973-1482http://imsear.searo.who.int/handle/123456789/213780Camrelizumab is a programmed death receptor-1 inhibitor originally developed in China for the treatment of refractory lymphoma. It has also been effective in non-small-cell lung cancer patients. However, the rechallenge of camrelizumab was not reported previously. We report the rechallenge of camrelizumab therapy in two patients previously treated with microwave ablation (MWA) and camrelizumab. Although objective responses were achieved, camrelizumab therapy was discontinued because of the development of immune-related pneumonia (IRP). Treatment with camrelizumab was reinitiated after the patients recovered from IRP. The reoccurrence of more severe IRP necessitated additional corticosteroid therapy. The rechallenge of camrelizumab in patients treated with MWA plus camrelizumab regimen and who developed IRP should be cautiousImmune-related pneumoniamicrowave ablationnonsmall-cell lung cancerJournal ArticleIndiaDepartment of Oncology, The First Affiliated Hospital of Shandong First Medical University&Shandong Provincial Qianfoshan Hospital, Shandong Lung Cancer Institute, Jinan, Shandong Province, ChinaDepartment of Oncology, Shandong Provincial Hospital Affiliated to Shandong First Medical University, Jinan, Shandong Province, ChinaDepartment of Oncology, The First Affiliated Hospital of Shandong First Medical University&Shandong Provincial Qianfoshan Hospital, Shandong Lung Cancer Institute, Jinan, Shandong Province, China
