NPJ Precis Oncol. Nejat Mahdieh, Majid Maleki, in Practical Cardiology (Second Edition), 2022. Would you like email updates of new search results? Additionally, the survival analysis for individual cancer types suggested that the PFS of the SWI/SNF-mutant group was significantly superior to that of the SWI/SNF-non-mutant group in colorectal cancer (NR vs. NR, HR=0.33 [0.190.59], p=0.0001; Additional file 2: Figure S2a) and gastric cancer (NR vs. 20.6months, HR=0.44 [0.190.97], p=0.0437; Additional file 2: Figure S2b); the same tendency was significant numerically but not statistically in non-small cell lung cancer (NR vs. 40.9months, HR=0.58 [0.331.02], p=0.0595; Additional file 2: Figure S2c). Furthermore, an overview of the possible biological functions and downstream signaling pathways using the GO database suggested that SWI/SNF genes and covariant genes were enriched in the PI3K signaling pathway (Additional file 3: Figure S3). 2012;28:130713. Next Generation Sequencing All information these cookies collect is aggregated and therefore anonymous. The PFS was not significantly different in SWI/SNF-mutant and -non-mutant groups in other cancers, which might be due to the relatively small number of cases involved in our study. The PFS of SWI/SNF-mutant and SWI/SNF-non-mutant were not markedly different in melanoma (d), soft tissue sarcoma (e), urothelial cancer (f), endometrial cancer (g) and other cancers (h).
