The role of hyaluronan (HA), serum-derived HA-associated protein (SHAP)-HA complex and hyaluronan synthase (HAS) in endometrial carcinomas was investigated. The relationship of metalloproteinase (MMP) and its inhibitor (TIMP) with HA and the SHAP-HA complex was also examined. The expression of HAS1 was related to the depth of myometrial invasion and lymph-vascular space involvement. The serum levels of HA, SHAP-HA complex, MMP-9, and TIMP-1 were increased in related with the depth of myometrial invasion, histological grade and lymph-vascular space involvement. They were also higher in the HAS1-positive group compared to -negative group. The serum concentrations of HA and SHAP-HA complex had a significant correlation with the MMP-9 and TIMP-1. The patients with elevated SHAP-HA complex had the shorter disease-free survival. The multivariate analysis revealed that the SHAP-HA complex was the independent variable for disease-free survival of endometrial cancer patients. In conclusion, the elevation of serum SHAP-HA complex depended on the HAS1 expression and the SHAP-HA complex is a useful marker to predict disease recurrence in endometrial cancer patients. The SHAP-HA complex may promote the lymph-vascular space involvement and the synthesis and activation of MMP-9 and TIMP-1 in the progression of endometrial cancer.

Endometrial cancer (EC) is a disease with good and poor prognostic subtypes. Dedifferentiated endometrial carcinoma (DEC), undifferentiated endometrial carcinoma (UEC), and clear cell endometrial carcinoma (CEC) are rare high-grade tumors, associated with a poor prognosis and high pathologic stage. Many studies have been performed on the programmed death-ligand 1 (PD-L1) axis mainly focus on endometrioid adenocarcinomas and little research has been done on rare subtypes. The present body of work aims to evaluate the role of indoleamine-2,3-dioxygenase (IDO-1) and stromal differentiation (SD), their correlation with clinicopathologic features and overall survival. Here we found that positive IDO-1 expression in immune cells correlated with worse disease-free survival ( p = 0.02), recurrence ( p = 0.03), high pathologic tumor stage ( p = 0.024), lymph node metastasis ( p = 0.028), and myometrial invasion ( p = 0.03). Our findings suggest IDO-1 to be relevant in both MMR intact and deficient tumors; however, >20% immune cell staining was restricted to MMR deficient cancers. For the stroma, immature, myxoid differentiation was found to correlate with worse disease-free survival ( p = 0.04). We also found the correlation between IDO-1 expression and immature stroma. Looking forward, IDO-1 could be promising for immunotherapy and SD could be the answer to clinical heterogeneity.

Background:Lysosomal protein transmembrane 4 β-35 (LAPTM4B-35), a novel oncoprotein that belongs to the mammalian 4-tetratransmembrane spanning protein superfamily, has been implicated in oncogenesis and cancer progression in several solid malignances. However, the expression of LAPTM4B-35 and its role in endometrial cancer progression remain unknown.Materials and Methods:We investigated the expression of the LAPTM4B-35 protein by immunohistochemistry in 30 normal endometrium specimens and 165 endometrial carcinomas and analyzed its correlation with various clinicopathologic features, including patient outcome.Results:LAPTM4B-35 immunoreactivity was overexpressed in endometrial carcinoma cases compared with normal endometrium (P < 0.001). High LAPTM4B-35 expression was found in 117 (70.91%) of these 165 carcinomas and was positively correlated with the International Federation of Gynecology and Obstetrics stage, histological grade, depth of myometrial invasion, lymph node metastasis, lymph vascular space involvement, and recurrence, but not with age and histological type. Patients with high LAPTM4B-35 expression had significantly poorer overall survival and disease-free survival compared with patients with low expression of LAPTM4B-35 (P = 0.001 and P = 0.002, respectively). Multivariate analysis showed that high LAPTM4B-35 expression was an independent prognostic factor for both overall survival and disease-free survival of patients with endometrial carcinoma (both P = 0.005).Conclusions:These results showed that high LAPTM4B-35 expression was associated with progression and prognosis of endometrial carcinoma.

5594 Background: Several studies suggest that systemic immune response (SIR) and local immune response (LIR) have independent roles in multiple types of cancer. In endometrial cancer (EC), the correlation between SIR and LIR and its prognostic value remains unclear. Methods: A total of 146 EC patients (stage I-IV) who had undergone surgery from 2009 to 2015, were identified from a prospective institutional database. Lymphocyte/monocyte ratio (LMR) to represent SIR was calculated from preoperative blood samples. The presence of intratumoral and peritumoral infiltrating lymphocytes (TILs) on hematoxylin and eosin-stained slides was considered as a surrogate of LIR. LMR and TILs were correlated to pathological findings and survival outcomes (overall survival: OS, disease free survival: DFS). Results: A LMR cutoff value of 4.4 for survival was determined based on receiver operating characteristic (ROC) curve analysis. LMR high was significantly associated with endometrioid histology (p=0.03), lower grade (G1-2; p=0.003), < 50% myometrial invasion (p=0.01) and I-II stage (p=0.02). TILs were correlated with MSI-high (p<0.005), but not with LMR (p=0.3). Low LMR was associated with worse 5-year OS rates (64.5% vs 93.9%; p<0.01) and presence of TILs with better 5-years OS rates (72% vs 27%; p=0.04). On multivariate analysis (table 1) LMR, histology, stage and grade remained independent prognostic factors for OS (p=0.01). Using the combination of LMR and TILs, four groups with decreasing 5-years OS rates were identified: LMR-high/TILs+ (100%) > LMR-high/no-TILs (87%) > LMR-low/TILs+ (71%) > LMR-low/no-TILs (61%). Conclusions: In our series of resected EC patients, SIR (defined by LMR) constituted an independent prognostic factor for OS and LIR for DFS. We did not find any correlation between SIR and LIR, but the combination of both higher SIR and LIR showed better OS. [Table: see text]

452 Background: Surgical resection is the only curative treatment for patients with gallbladder cancer, despite surgical advances many patients ultimately develop recurrent disease. Management of resected gallbladder cancer mostly relies on single-arm trials and retrospective observations. The purpose of our study is to assess the role of adjuvant therapy in stage I-III gallbladder cancer patients who have undergone surgical resection. Methods: Clinical data were collected on 251 patients who underwent surgical resection for stage I-III gallbladder cancer and presented to Mayo clinic from January 2000-December 2015. Patients were then classified into adjuvant treatment group and surveillance only group. Overall survival and recurrence were compared between the two groups. Results: 78 (31.1%) patients received adjuvant therapy while 173 patients were observed only. Patients who received adjuvant tended to be younger (63.0[SD 11] vs 66.2 [SD 13.1]), have higher stage, and underwent extended surgery. Most patients received chemoradiotherapy (55) with 5-Fluorouracil (67.3%) and capecitabine (25.5%) as radiosensitizing agents. 21 patients received additional adjuvant chemotherapy. 27% of patients received chemotherapy as the sole adjuvant treatment. The most common chemo regimens included gemcitabine (52.3%) and gemcitabine plus cisplatin combination (23.8%). On multivariate analysis patients > 65 years(HR 1.53 [1.07-2.19], p = 0.02), males (HR 1.7 [1.2-2.4], p = 0.003), positive margins (2.77 [1.69-4.38], p < 0.01), and stage III (HR 1.91 [1.35-2.70], p < 0.01) had worse overall survival. Patients who underwent extended radical resection (HR 0.73 [0.51-1.05], p = 0.09) had better overall survival. Adjuvant therapy had no statistical significant effect on overall survival (HR 1.10 [0.75-1.59], p = 0.63 or disease free survival (HR 1.05 [0.69-1.59], p = 0.81) on overall population. However, in stage IIIB, patients receiving adjuvant therapy had better overall survival (HR 0.51 [0.25-1.01], p = 0.05) and disease free survival (HR 0.45 [0.19-1.09], p = 0.06). Conclusions: In our study, adjuvant treatment, especially chemoradiation therapy, was only beneficial in patients with stage IIIb gallbladder cancer patients.

ObjectivesThe aim of this study was to evaluate the immunohistochemical (IHC) expression of Ki-67, estrogen receptors α (ERsα), and progesterone receptors (PRs) in high-risk endometrial cancer patients and to assess their prognostic impact.Methods/MaterialsImmunohistochemical expression of Ki-67, ERsα, and PRs was evaluated in primary untreated endometrial cancer. The correlation among IHC staining and risk factors of recurrence such as age, Federation International of Gynecology and Obstetrics stage, grading, depth of invasion, and metastatic spread was assessed.ResultsEighty-two patients were available for the analysis. Mean ± SD age was 65.05 ± 10.48 years. The IHC assessment revealed a lack of ERα in 46.3% and of PR in 48.7% as well as a high Ki-67 in 31.7%. Loss of ERα and PR was associated with a significant higher rate of advanced stage of disease, a higher frequency of G3 tumors, and a myometrial invasion greater than 50%. A strong Ki-67 expression correlated with a deeper myometrial invasion. Analysis of the interrelationship between receptor immunonegativity revealed a relevant association of ERα immunolocalization with PR and with a high Ki-67 expression. The present study also showed that loss of ERα (P = 0.003), advanced Federation International of Gynecology and Obstetrics stage (P < 0.001), and high Ki-67 (P = 0.004) were independent prognostic factors of a shorter disease-free survival. Importantly, loss of ERα, loss of PR, and a high Ki-67 were correlated with a higher incidence of distant recurrence.ConclusionsA systematic immunohistochemistry should be a key step in the therapeutic algorithm and could contribute to the identification of high-risk tumors.

Breast cancer is the most common malignancy in women. It is an immensely heterogeneous disease, characterised by a broad variety of clinical development. The research in recent years has focused on finding new markers of prognosis. This study investigates the role of expression of the bcl-2 protein in breast cancer. We analysed bcl-2 expression in 57 women with primary breast carcinoma who were treated with neoadjuvant (primary) chemotherapy, followed by a surgical procedure. The bcl-2 expression was correlated with other clinicopathological characteristics of the tumour – histological grade, stage, expression of hormonal receptors, proliferation rate, and with the survival of the patients. No significant association of bcl-2 expression with either overall survival or disease free survival was found.
