BRCA1 and colon mucinous adenocarcinoma: Compared to the BRCA1 mRNA-high group, the BRCA1 mRNA-low group of CRC patients had a higher proportion of tumors in more advanced lymph node stages (N1/N2) (Figure 4B), a slightly higher frequency of patients with stage IV CRC (Figure 4C), a slightly higher metastasis score (Figure 4F), and had a greater frequency of mucinous adenocarcinomas (Figure 4H).
