Moreover, the fact that the HT29 H3K27me3 profile, as compared to SW480, shows higher overlap with tissues and is enriched in developmental processes, can be explained by the fact that HT29 is a low grade CRC cell line (grade II), while SW480 is a high grade (grade III-IV), poorly differentiated and highly abnormal CRC cell line.
Progression-free survival and overall survival of patients with a high grade (grade 2 3) of skin toxicity were significantly longer than those with a low grade (grade 0 1) of skin toxicity (median progression-free survival, 6.4 months vs 2.4 months, P < 0.001; median overall survival, 14.6 months vs 7.1 months, P = 0.006).
This probability decreased gradually over time, and after T4 the probability of having a higher grade (grade 2 or 3) had increased to 0.22, which further increased to 0.35 at T6. Another cluster of progression was cluster D (n = 47, 1.4%), characterized as "fast progression from minimal or moderate to (pre proliferative or treated retinopathy".

TMA-1 consisted of both low grade (Grade 1, n = 15) and high grade (Grade 3, n = 74) ductal carcinomas [ 29].
Additionally, there was no significant difference between low-grade (grade 1 and 2) and high grade (grade 3) tumors with regard to HPV infection (36%Vs.33.3%%, P = 0.59).
