Conditions

Epithelial High Grade Serous Ovarian Cancer

Keywords

immune microenvironment, CD8+ T cells, plasma cells, Tertiary lymphoid structures

Brief summary

The study seeks to evaluate the presence and correlation with clinical outcome of several components of adaptive immunity (TILs, TLS, plasma cells and PD-L1 expression) in tumor specimens of patients with EOC treated with carboplatin/paclitaxel chemotherapy.

Interventions

OTHERAssessment of elements of adaptive immunity in tumor biopsies

Tertiary lymphoid structures, Plasma cells, p53 and CD8+ T cells will be evaluated at tumor biopsies of patients with advanced ovarian cancer treated with chemotherapy.
