Background And Objective: Thymic epithelial tumors, including thymomas and thymic carcinomas, represent the most common mediastinal tumors and account for up to 50% of all anterior mediastinal tumors. For early stages of these thymic tumors, complete resection of the entire thymus is the recommended treatment. The transition from open surgery to video-assisted thoracoscopic surgery (VATS) and recently to robotic-assisted thoracic surgery (RATS) has fundamentally altered the treatment of thymic tumors.

We studied the expression levels of microRNAs (miR-21, miR-27a, miR-221, and miR-429) in the thymus of female Wistar rats after surgical treatment of breast cancer (BC) and after photodynamic therapy for BC followed by tumor resection. In the group without treatment, the levels of pro-oncogenic miR-21, miR-27a, and miR-221 in the thymus were reduced in comparison with those in the group of intact control. After surgical treatment of BC, the levels of miR-21 and miR-27a in the thymus increased in comparison with those in BC without treatment.

Background: Chronic graft-versus-host disease (cGVHD) manifests with characteristics of autoimmune disease with organs attacked by pathogenic helper T cells. Recent studies have highlighted the role of T cells in cGVHD pathogenesis. Due to limited understanding of underlying mechanisms, preventing cGVHD after allogenic hematopoietic cell transplantation (HCT) has become a major challenge.

As multiple front-line immune checkpoint inhibitor (ICI)-based combinations are approved for metastatic renal cell carcinoma, biomarkers predicting for ICI responses are needed past clinical prognostication scores and transcriptome gene expression profiling. Circulating markers represent opportunities to assess baseline and dynamic changes in immune cell frequency and cytokine levels while on treatment. We conducted an exploratory prospective correlative study of 33 patients with metastatic clear cell renal cell carcinoma undergoing treatment with ICIs and correlated changes in circulating immune cell subsets and cytokines with clinical responses to treatment.

Introduction: Thymomas and thymic carcinomas are rare anterior mediastinal tumours, accounting for 0.2-1.5% of all cancers.
