ADAM-10 (CDw156, CD156c, and kuzbanian) is a protein belonging to a superfamily of metalloproteases, enzymes capable of degrading the extracellular matrix. ADAMs have also been shown to be primarily involved in ectodomain cleavage. The aim of the study was to assess the expression and intracellular location of ADAM-10 in 104 primary skin melanomas and 16 metastatic lesions from regional lymph nodes. Also, prognostic significance of ADAM-10 expression in primary tumor cells and metastatic lesion cells was evaluated during 5-year observation. It was revealed that high expression of ADAM-10 positive cells was strictly related with lower intensity of tumor-infiltrating lymphocytes (P=0.037), which suggests that ADAM-10 regulates immunoresponse in melanoma initiation and progression. No statistically significant correlations were found between ADAM-10 expression in primary tumor cells and nodal metastases and other histopathological parameters analyzed. Decreased immunoreactivity of ADAM-10 in cancer cells from regional lymph nodes was correlated with worse prognosis; however this correlation was statistically nonsignificant (P=0.065). Review of the literature shows that our study is the first one ever to describe the significance of ADAM-10 expression in correlation with detailed histopathological parameters of the primary tumor and data on long-term survival of cutaneous melanoma patients.

475 Background: The prognostic importance of the local antitumor immune response in colorectal carcinoma (CRC) is well established. Recent studies suggest that systemic antitumor immunity may also impact on survival. This study aimed to determine the relationship between peripheral blood lymphocyte counts (PBLCs), reactive features in regional lymph nodes, local tumoral/peri-tumoral lymphocytic inflammation and survival in stage II CRC. Methods: Resection specimens from 185 patients with stage II CRC were assessed for peri-tumoral lymphocytic inflammation, tumor-infiltrating lymphocytes, lymph node yield, lymph node size, and reactive changes in individual lymph nodes. Reactive changes were scored semi-quantitatively and given a reactivity [R] score of 1-4 based on the presence and size of germinal centers. Pre-operative PBLCs and neutrophil counts were recorded. Results: Lower peripheral lymphocyte counts were associated with advanced age (p = 0.016), T4 disease (p = 0.006), venous invasion (p = 0.006), lymph node yields <12 (p = 0.024), smaller mean nodal diameters (p = 0.021), absence of tumor-infiltrating lymphocytes (p = 0.002) and fewer highly-reactive lymph nodes (R score 4) per case (p = 0.032). Cox regression analysis revealed that advanced age (Hazard Ratio, 1.03 per year [95% confidence interval, 1.01-1.05]; p = 0.015) and higher peripheral lymphocyte counts (HR, 0.52 per 1x109cells/L [95% CI, 0.31-0.86]; p = 0.011) were independently predictive of disease-free survival. Neutrophil counts were not associated with outcome. A higher neutrophil to lymphocyte ratio was associated with worse survival on univariate, but not multivariable analysis. Conclusions: The PBLC is an independent predictor of survival in stage II CRC, and is significantly associated with the immune status of regional lymph nodes and the local lymphocytic immune response.

e14035 Background: The immune response to melanoma has been shown to be locally affected by presence of tumor-infiltrating lymphocytes (TILs), generally divided into brisk (infiltrating the entire base of the invasive tumor), non-brisk (infiltrating only focally) and absent. Several studies showed that greater presence of TILs, especially brisk, in primary melanoma is associated with a better prognosis and a higher survival rate. Since recent studies revealed an association between PD-1/PD-L1 expression levels and tumor response, the aim of our study was to investigate the correlation between plasma PD-1 and presence/absence/class of TILs in metastatic melanoma patients. Methods: The plasma PD-1 levels were analyzed in 28 patients with metastatic melanoma using a specific ELISA assay. The characterization of TILs in tumor tissue was performed by immunohistochemistry. Statistical analysis was assessed using t-Student and ANOVA tests. Survival curves were estimated by using the Kaplan-Meier method and log-rank test to evaluate significant differences among them. Results: 16 out of 28 patients showed the presence of TILs in primary tumor, 10 of which brisk and 6 nonbrisk. The plasma PD-1 levels were analyzed in relation to the presence/absence of TILs (p = 0.022), brisk TILs versus nonbrisk/absent TILs (p = 0.014), and brisk vs nonbrisk vs absent TILs (p = 0.032). In particular, low plasma PD-1 levels have been shown to be associated with brisk TILs in primary melanoma, intermediate values with nonbrisk TILs, and high expression with absent TILs. Although the low number of samples did not allow us to obtain a statistically significant association between the plasma PD-1 expression levels and overall survival (OS) depending on the absence or presence of TILs (brisk/nonbrisk), however the median survival of patients having brisk TILs was five months higher than other 2 groups of patients with absent and nonbrisk TILs, respectively. Conclusions: This work highlights, for the first time, the potential ability of using the plasma PD-1 levels to predict prognosis also in patients with metastatic melanoma at diagnosis for which it is not possible to identify the primary tumor.

AbstractThe level of stromal tumor-infiltrating lymphocytes (sTILs) in triple-negative (TNBC) and HER2-positive breast cancers convey prognostic information. The importance of systemic immunity to local immunity is unknown in breast cancer. We previously demonstrated that histological alterations in axillary lymph nodes (LNs) carry clinical relevance. Here, we capture local immune responses by scoring TILs at the primary tumor and systemic immune responses by recording the formation of secondary follicles, also known as germinal centers, in 2,857 cancer-free and involved axillary LNs on haematoxylin and eosin (H&E) stained sections from a retrospective cohort of 161 LN-positive triple-negative and HER2-positive breast cancer patients. Our data demonstrate that the number of germinal center formations across all cancer-free LNs, similar to high levels of TILs, is associated with a good prognosis in low TILs TNBC. This highlights the importance of assessing both primary and LN immune responses for prognostication and for future breast cancer research.

A calf with a lymphoproliferative disease resembling human mycosis fungoides, had multiple, ulcerated skin nodules with enlarged regional lymph nodes. Tumor cells were 10–15 μm in diameter and had round to oval nuclei without indentations. Mitoses were regularly present. Pautrier's microabscesses were in the epidermis, and T-cell areas of regional lymph nodes were infiltrated by neoplastic cells. Demonstration of the T-helper/inducer origin of neoplastic lymphocytes suggested classification in analogy with human mycosis fungoides.
