Abstract:
Aim: To examine and understand patient characteristics, treatment patterns and outcomes for patients with metastatic synovial sarcoma (mSS) treated in a US community setting. Materials & methods: Retrospective observational study in adults with mSS in The US Oncology Network (diagnosed January 2012-December 2018). Results: Of 202 patients diagnosed with synovial sarcoma (SS), 71 had mSS. Of 39 patients with mSS who received first-line (1L) systemic treatment, 25 and 16 continued to 2L and 3L+ treatment, respectively. With each subsequent treatment line, time-to-treatment-discontinuation (1L-3L: 3.9-2.7 months) and time-to-next-treatment (1L-3L: 9.3-4.6 months) decreased. At 1L, median overall survival was 24.5 months. Conclusion: This study highlights the ongoing need for effective therapies for mSS.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
