Assessment of the Functional Outcome and Quality of Life in Sarcoma Patients

Primary bone and soft tissue sarcomas are an exceptionally rare form of cancer, collectively accounting for only 1% of all malignancies diagnosed. Sarcomas often occur in the patients' extremities and treatment typically involves limb salvage surgery with bone and/or muscle resection. These surgeries often leave the patients with disfigurements, psychological trauma, and functional disabilities. Perhaps, the most difficult and life-altering decision that patients (and their parents) with primary bone sarcomas about the knee joint have to make, involves choosing the type of surgical procedure that will provide them with the outcome that meets their functional as well as aesthetic expectations. In literature, the quality of life for patients with osteosarcoma around the knee joint after three different surgical procedures, that is, amputation, endoprosthetic reconstruction and rotationplasty was evaluated. There was found that patients treated with rotationplasty showed significantly higher functional scores compared to the two other groups of patients. Also, researchers investigated the long-term quality of life after bone sarcoma surgery around the knee joint and found that, despite the functional disability, survivors were busy with work, study, relationships, and sometimes they have founded a family. Most published reports in the literature on assessment of gait in the lower-extremity sarcoma survivors were focused on bone sarcoma patients after wide resection and endoprosthetic reconstruction. To the knowledge of the investigator, there has been no published studies on gait analysis after resection of soft tissue sarcomas (STS) of the lower extremity. The rare and heterogeneous aspects of STS and the paucity of knowledge of movement strategies in these patients hinder the development of effective rehabilitation protocols for recovering movement after resection of STS in the lower limb.

Atezolizumab Plus Tivozanib in Immunologically Cold Tumor Types

Checkpoint inhibitor therapy represents a significant advance in cancer care. The interaction between PD-1 and PD-L1 induces immune tolerance, and the inhibition of this interaction is an effective treatment strategy for numerous malignancies. Despite its demonstrated potential, immunotherapy is not currently thought to be an effective intervention in the treatment of several immunologically "cold" tumors such as prostate cancer, biliary tract cancers, soft tissue sarcomas, well-differentiated neuroendocrine tumors, microsatellite stable colorectal cancer, pancreatic cancer, and non-triple negative breast cancer. Vascular endothelial growth factor (VEGF) is thought to play a key role in modulating the anti-tumor immune response. Vascular endothelial growth factor (VEGF) is secreted by tumors and leads to endothelial cell proliferation, vascular permeability, and vasodilation. This in turn leads to the development of an abnormal vasculature with excessive permeability and poor blood flow, limiting immune surveillance. In addition, VEGF inhibits dendritic cell differentiation, limiting the presentation of tumor antigens to CD4 and CD8 T cells. Vascular endothelial growth factor (VEGF). VEGF tyrosine kinase inhibitors (TKIs) VEGF-TKIs are currently utilized in the treatment of a variety of malignancies and are widely utilized in combination with checkpoint blockade in the treatment of clear cell kidney cancer. Through the inhibition of VEGF, it may be possible to potentiate the effect of immune checkpoint blockade even in tumors which have traditionally been thought to be unresponsive to immunotherapy. This study aims to evaluate the combination of the immune checkpoint inhibitor atezolizumab and the VEGF-TKI tivozanib in a variety of tumors which have a low response rate to checkpoint inhibitor therapy alone.
