e15613 Background: Within the tumor microenvironment (TME), infiltrating lymphocytes and myeloid cells including tumor-associated macrophages (TAMs) and tumor-associated neutrophils (TANs) are key players involved in liver cancer progression. The purpose of the study was to explorer whether distinct infiltrated immune cell features differentially affect clinical outcome in hepatocellular carcinoma (HCC). Methods: We obtained respectable stage II HCC specimens, along with adjacent para-tumor tissues from 221 patients who underwent surgical resection at Eastern Hepatobiliary Surgery Hospital, (in Shanghai, China) from 2015 through April 2018. CD8+, CD163+ and CD66B+ tumor-infiltrating lymphocytes (TILs) in the cancer area (CA) and stroma area (SA), as well paratumor stroma area, were analyzed by multiple immunohistochemistry. Results: Hierarchical clustering analysis of immune cell densities revealed that all HCC samples can be classified into three distinct groups. The three immune oncology types (IO-types) were characterized by a strong CD8 T cell density in CA and SA region (IO-1), an intermediate state of CD8 and CD163+ (IO-2), and a strong CD163+ macrophage density in IO-3. Remarkably increasing risks of mortality and recurrence, as well as elevated AST, ALP, GGT and AFP levels, were identified in IO-3 group, when compared with IO-1 group. We then identified that percentages of CA-CD8+ TILs in the tumor sample and SA-CD163+ macrophages in the para-tumor region showed opposite distribution pattern among the three IO types, suggesting a predictive role for CD8/TAM ratio in HCC cohort. Therefore, we next classified all HCC samples into two subgroups, according to the levels of tumor-CA-CD8/paratumor-SA-CD163 ratio. Expectedly, higher rate of CD8/CD163 represented significantly improved overall survival (OS) and progression free survival (PFS), verses lower rate of CD8/CD163. Further association studies suggested that the two subgroups correlated with HBV DNA, tumor size, and microvascular invasion (MVI). Of note, a prognostic signature combining portal vein tumor thrombus (PVTT) and CD8/CD163 ratio discriminated HCC patients into four subtypes with increasing risk of mortality and recurrence. Conclusions: The current results indicated that the CD8/CD163 is a novel, independent prognostic factor for a lower rate of disease recurrence and favorable OS in patients with resectable HCC.

In patients with pancreatic ductal adenocarcinoma (PDAC), the tumor microenvironment consists of cellular and stromal components that influence prognosis. Hence, tumor-infiltrating lymphocytes (TILs) may predict prognosis more precisely than conventional staging systems. Studies on the impact of TILs are heterogeneous and further research is needed. Therefore, this study aims to point out the importance of peritumoral TILs, tumor-infiltrating neutrophils (TINs), and immune subtype classification in PDAC. Material from 57 patients was analyzed with immunohistochemistry performed for CD3, CD8, CD20, CD66b, α-sma, and collagen. Hot spots with peritumoral TILs and TINs were quantified according to the QTiS algorithm and the distance of TILs hot spots to the tumor front was measured. Results were correlated with overall (OS) and progression-free survival (PFS). High densities of peritumoral hot spots with CD3+, CD8+, and CD20+ TILs correlated significantly with improved OS and PFS. Combined immune cell subtypes predicted improved OS and PFS. High infiltration of CD3+ TILs predicted progression after 12 months. The location of TILs’ hot spots and their distance to the tumor front did not correlate with patient survival. Peritumoral TILs and the composition of the stroma predict OS and PFS in PDAC.

e15612 Background: The achievements of immune checkpoint blockade strengthen the concept that tumor outgrowth and development are comprehensively regulated by immune system. The aim of the study was to explorer whether distinct infiltrated immune cell features differentially affect clinical outcome in hepatocellular carcinoma (HCC). Methods: We obtained respectable stage II HCC specimens, along with adjacent para-tumor tissues from 221 patients who underwent surgical resection at Eastern Hepatobiliary Surgery Hospital, (in Shanghai, China) from 2015 through April 2018. CD8+ and CD68+ tumor-infiltrating lymphocytes (TILs) in the cancer area (CA) and stroma area (SA), as well as PD-1/PD-L1 expression, were analyzed by multiple immunohistochemistry. Results: The density of CD8+ TILs were significantly associated with gender, tumor size, and cirrhosis; while the density of CD68+ TILs were associated with copies of HBV DNA and anti-viral treatment. Multivariate Cox regression analysis revealed that high densities of CD8+ TILs and low densities of CD68+/CD8+ ratios independently predicted better outcomes. Of note, a prognostic signature combining clinic features [portal vein tumor thrombus (PVTT) and tumor size (TS)] and CD8+ TILs densities discriminated HCC patients into four subtypes with increasing risk of mortality: PVTT-negative/TS-small/CD8-high (6.8% of cases), PVTT-negative/TS-small/CD8-low (45.7%), PVTT-negative/TS-large (34.4%) and PVTT-positive (13.1%). Further association studies suggested that the four subgroups correlated with gender, tumor envelope, microvascular invasion (MVI), and SA-PD1 expression. Similarly, a prognostic signature combining PVTT, TS and CD68+/CD8+ ratios discriminated HCC patients into four subtypes with increasing risk of recurrence. Conclusions: Combined immune features including CD8+ and CD68+ lymphocyte infiltration and clinic characteristics are useful prognostic biomarkers for HCC patients.

Ovarian cancer is the most lethal of gynecological cancers with 5-year survival rate of ca. 45%. The most common histologic subtype is high-grade serous carcinoma, which typically is presented with advanced stage and development of chemoresistance. Therefore, new treatment options, including immunotherapies, are needed. Understanding the features of the immune cell populations in the tumor microenvironment is essential for developing personalized treatments and finding predictive biomarkers. Digital image analysis may enhance the accuracy and reliability of immune cell infiltration assessment in the tumor microenvironment. The aim of this study was to characterize tumor microenvironment in a retrospective cohort of high-grade serous carcinoma samples with whole-slide imaging and digital image analysis. Formalin-fixed paraffin-embedded high-grade serous carcinoma tumor tissue samples (n = 67) were analyzed for six immunohistochemical stainings: CD4, CD8, FoxP3, granzyme B, CD68, and CD163. The stained sample slides were scanned into a digital format and assessed using QuPath 0.1.2 and ImageJ software. Staining patterns were associated with clinicopathological data. The higher numbers of intraepithelial CD8+, CD163+, and granzyme B+ immune cells were associated with survival benefit when analyzed individually, while high levels of both CD8+ and granzyme B+ tumor-infiltrating lymphocytes were an independent prognostic factor in the Cox multivariate regression analysis (median progression-free survival; hazard ratio = 0.287, p = 0.002). Specimens taken after administration of neoadjuvant chemotherapy presented with lower FoxP3+ tumor-infiltrating lymphocyte density (Fisher’s exact test, p = 0.013). However, none of the studied immunomarkers was associated with overall survival or clinical factors. Tumors having high amount of both intraepithelial CD8+ and granzyme B+ tumor-infiltrating lymphocytes showed better progression-free survival, possibly reflecting an activated immune state in the tumor microenvironment. The combined positivity of CD8 and granzyme B warrants further investigation with respect to predicting response to immune therapy. Neoadjuvant chemotherapy may have an effect on the tumor microenvironment and therefore on the response to immuno-oncologic or chemotherapy treatments.

Clinical follow-up aided by changes in the expression of circulating microRNAs (miRs) may improve prognostication of pancreatic ductal adenocarcinoma (PDAC) patients. Changes in 179 circulating miRs due to cancer progression in the transgenic KrasG12D/+; Trp53R172H/+; P48-Cre (KPC) animal model of PDAC were analyzed for serum miRs that are altered in metastatic disease. In addition, expression levels of 250 miRs were profiled before and after pancreaticoduodenectomy in the serum of two patients with resectable PDAC with different progression free survival (PFS) and analyzed for changes indicative of PDAC recurrence after resection. Three miRs that were upregulated ≥3-fold in progressive PDAC in both mice and patients were selected for validation in 26 additional PDAC patients before and after resection. We found that high serum miR-125b-5p and miR-99a-5p levels after resection are significantly associated with shorter PFS (HR 1.34 and HR 1.73 respectively). In situ hybridization for miR detection in the paired resected human PDAC tissues showed that miR-125b-5p and miR-99a-5p are highly expressed in inflammatory cells in the tumor stroma, located in clusters of CD79A expressing cells of the B-lymphocyte lineage. In conclusion, we found that circulating miR-125b-5p and miR-99a-5p are potential immune-cell related prognostic biomarkers in PDAC patients after surgery.

Until recently cancer medical therapy was limited to chemotherapy that could not differentiate cancer cells from normal cells. More recently with the remarkable mushroom of immunology, newer tools became available, resulting in the novel possibility to attack cancer with the specificity of the immune system. Herein we will review some of the recent achievement of immunotherapy in such aggressive cancers as melanoma, prostatic cancer, colorectal carcinoma, and hematologic malignancies. Immunotherapy of tumors has developed several techniques: immune cell transfer, vaccines, immunobiological molecules such as monoclonal antibodies that improve the immune responses to tumors. This can be achieved by blocking pathways limiting the immune response, such as CTLA-4 or Tregs. Immunotherapy may also use cytokines especially proinflammatory cytokines to enhance the activity of cytotoxic T cells (CTLs) derived from tumor infiltrating lymphocytes (TILs). The role of newly discovered cytokines remains to be investigated. Alternatively, an other mechanism consists in enhancing the expression of TAAs on tumor cells. Finally, monoclonal antibodies may be used to target oncogenes.

Abstract   Significant advances have been made in our understanding of the tumor immune microenvironment (TIM) and tumor infiltrating lymphocytes (TILs). Nevertheless, there is little understanding of the changes in the TIM in response to neoadjuvant chemoradiotherapy (CRT). Thus, our aim was to investigate the changes in the TIM with neoadjuvant CRT in EC by assessing the immune cell infiltrate, the expression of immune related genes, and their association with treatment response and prognosis. Methods To decipher the effects of neoadjuvant CRT on the TIM, we obtained 58 paired pre-treatment and post neoadjuvant CRT treated EC specimens. TILs and tumor infiltrating neutrophils (TIN) were quantified in pre-treatment biopsies and surgical resection specimens following neoadjuvant CRT. To evaluate the immune transcriptomics, RNA was extracted from these specimens and gene expression was assessed using the Nanostring Platform based on the PanCancer Immune Profiling Panel. Immunohistochemistry (IHC) was performed to validate findings from the immune transcriptomics. Results TIL counts were not prognostic for disease specific survival (DSS). We observed higher expression of immune-suppressive inflammatory chemokines (TGFß-1 and IL-16) in post-neoadjuvant treated samples compared to pre-treatment biopsies. In samples collected after neoadjuvant CRT, low expression of genes related to anti-tumor T cell cytotoxic activity1 was significantly associated with disease recurrence. In patients with residual disease, multivariate analysis revealed a high neutrophil count, but not TIL count, was significantly associated with inferior DSS (HR 3.8 [1.3– 10.8]; p = 0.01). Conclusion In EC, the tumor microenvironment after neoadjuvant CRT remains largely immune-suppressive. We discovered that the presence of TINs in patients with residual disease post neoadjuvant CRT is an independent adverse prognostic factor. Collectively, our results suggest that an inflammatory pro-tumoral microenvironment associated with TINs may contribute to treatment resistance and progressive disease in EC.
