CD68 and ovarian carcinoma: Previous studies demonstrated the positive predictive value of classically activated (M1) over tumour-promoting (M2) macrophages in ovarian cancer.9,34 However, no significant association was found between the level of intra-epithelial CD68 infiltrate and patient survival.4 Our study confirms this latter result and also demonstrates a significant association between a high coverage of stromal areas with CD68+ macrophages and improved overall survival.
