Furthermore, the protein level of RPL15 was prominently correlated with TNM stage (I vs. II vs. III vs. IV, p = 0.033), T classification (T1-2 vs. T3-4; p = 0.035), vascular invasion (absent vs. present; p = 0.045) and histological differentiation (well vs. moderate/poor; p = 0.005) among Renji cohort 2 patients (Table 2); whereas no significant relevance was found with age, gender, tumor location, tumor size, CA199 level, lymph node metastasis and distant metastasis. The gene discussed is RPL15; the disease is neoplasm.
