We identified 42 DEs and established 6 survival-related snoRNAs using Cox analysis: 2 of the 6 snoRNAs, SNORA16B and SNORD63, are protective factors, and the other 4 (SNORA59B, SNORD11, SNORD46, and SNORD 124) are risk factors that may play a crucial role in tumor metastasis and progression. The gene discussed is SNORD11; the disease is neoplasm.
