Nevertheless, studies in renal cell [15], head and neck [16], bronchioloalveolar [17] and oesophageal carcinoma [18] have demonstrated association between the presence of intratumoral CD66b+ neutrophils and poor prognosis, while in gastric and colorectal carcinoma high levels of CD66b+ neutrophils indicated a favorable prognosis [19, 20]. Here, CEACAM8 is linked to colorectal carcinoma.
