Immune heterogeneity was associated with platinum response and might represent a selection marker for personalized therapy. = 0.015, Table S1). The presence of ascites before surgery (= 0.083) and macroscopic residual tumor after surgery (= 0.067) showed a pattern to reduced platinum-sensitivity. In accordance with these results, the presence of metastases (= 0.031, = 0.035), macroscopic residual tumor after surgery (= 0.01, = 0.005), and vascular invasion (= 0.006, = 0.03) correlated significantly with shorter PFS (Physique S1). 2.2. Immune Infiltrate in Primary Tumor All immune cell phenotypes were detected in the stromal area of BGJ398 inhibition the primary tumor in a higher fraction compared to the intratumoral area. This obtaining was impartial from the method of evaluation. The highest density was observed for CD45+ cells, followed by CD3+ cells, CD8+ cells, and PD-1+ cells (Table 2). Table 2 Density and spatial distribution of immune cell phenotypes in different lesions of ovarian cancer. = 0.042). All patients with a strong (rating 2) CD45+ intratumoral infiltrate in primary tumor were suffering from ascites (= 0.006). Vascular invasion significantly correlated with a high ( 73 counts/mm2) density of PD-1+ cells in the stromal area of the primary tumor (= 0.013). PD-L1 positivity was found BGJ398 inhibition more often in primary tumors with distant metastasis (86%) compared to cancers without distant metastasis (51%, = 0.049). A high intratumoral density ( BGJ398 inhibition 88 matters/mm2) of Compact disc8+ cells was mostly observed in old sufferers ( 62 years, 78%, = 0.037). Major tumors with a higher ( 201 matters/mm2) intratumoral Compact disc3+ cell thickness showed a craze to complete platinum-sensitivity (= 0.057, Desk 3). Desk 3 Defense cell phenotypes of major tumor and matching lesions with regards to platinum-sensitivity. = 0.007, Desk S3). Furthermore, in 16 situations (70%), the omental lesion demonstrated a higher thickness of stromal Compact disc3+ and Compact disc8+ cells set alongside the major tumor (= 0.005 and = 0.012, Figure 1). Therefore, the mean count number in omental lesions of stromal CD8+ and CD3+ cells was almost 2 times higher. In addition, nearly all omental lesions (65%) uncovered an increased infiltrate of stromal PD-1+ cells (= 0.013). There is no factor in intratumoral matters comparing major tumors and omental lesions.

Matters of (A) Compact disc3+, (B) Compact disc8+, and (C) PD-1+ (designed cell-death protein 1) stromal cells. Matters of Compact disc3+, Compact disc8+, and PD-1+ cells have already been higher in the omental lesions significantly. = 0.054, Figure 2). Conversely, only 1 case (7%) demonstrated a higher appearance of PD-L1 in the principal tumor, although it was similar or low in most sufferers (93%, = 0.074).

(B) PD-L1 (programmed cell-death ligand 1) appearance has been somewhat higher in peritoneum. = 11, = 0.018, Desk S4). Many tumors with lymph node metastases (87%) uncovered more stromal Compact disc3+ cells in the omental lesion than in the principal tumor (= 0.037). No significant correlations have already been discovered for peritoneal lesions (Desk S5). Interestingly, immune system heterogeneity between peritoneal lesions and.
