CD163 and telomere syndrome: In a study of 75 STS cases, a high number of CD68+, CD163+, and CD204+ macrophages in both the intratumoral and marginal areas was associated with worse disease-free survival (DFS); however, after the division of this group into grade 1 and grade 2/3, only in the grade 2/3 group were high numbers of CD163+ and CD204+ macrophages associated with poor DFS, and only in the marginal area [73].
