Immunohistochemical markers that might be associated with good survival in cohorts 1 and cohort 2 were (respectively): high K/L+ infiltration in tumour stroma [p = 0.124; OR 2.682 (95%CI 0.762–15.248] and p = 0.067; OR 2.589 [95%CI 0.934–7.171)], high CD79A+ infiltration in tumour stroma [p = 0.110; OR 2.740 (95%CI 0.795–9.443)] and p = 0.095; OR 2.443 [95%CI 0.856–6.978)], and a 100% desmoplastic growth pattern [p = 0.157; OR 2.709 (95% CI 0.682–10.768) and p = 0.040; OR 5.858 (95%CI 1.083–31.693)]. Here, CD79A is linked to neoplasm.
