Purpose. To compare the expression level of apelin in muscle-invasive bladder cancer and matched paracarcinoma tissues and investigate the relationship between apelin and clinical prognosis in the patients. Methods. To assess apelin expression by using immunohistochemical method compared with bladder tumors and matched paracarcinoma tissues. Subsequently, the correlation of apelin expression with the clinicopathological features of bladder cancer patients was analyzed. Kaplan-Meier survival curves method was used to analyze apelin prognostic significance for muscle-invasive bladder cancer patients (including 404 muscle-invasive bladder cancer patients and 28 normal bladder tissues, in TCGA dataset). Results. Apelin protein level was overexpressed in bladder tumor tissues compared with paracarcinoma tissues. Furthermore, high apelin expression was associated with high tumor stage (P<0.05), distant metastasis (P<0.05), and vascular invasion (P<0.05). Kaplan-Meier curve analyses showed that the overexpression of apelin was a potential predictor of overall survival and disease-free survival. Conclusion. Apelin was upregulated in bladder tumor tissues compared with matched adjacent noncancer tissues, especially in the high tumor stage, distant metastasis, and vascular invasion. What is more, high expression of apelin in muscle-invasive bladder cancer indicates the poor prognosis. These data suggested that apelin might be a therapeutic potential biomarker in muscle-invasive bladder cancer patients.

Urothelial bladder cancer (BCa) is the ninth most commonly diagnosed cancer worldwide and accounts for approximately 3% of global cancer diagnoses. We are interested in prognostic markers that may characterize tumor cells (TCs) and immune cells (ICs) and their relationship in BCa. A potential candidate marker that meets these criteria is progranulin (GP88), which is expressed separately in TCs and ICs. We analyzed GP88 expression by immunohistochemistry (IHC) in 196 muscle-invasive BCa samples using a tissue microarray. The immunoreactive score for GP88 staining in TCs and the percentage of GP88-positive ICs was determined. An easy cutoff for the staining status of TCs (positive vs. negative) and ICs (0% vs. >0%) and, more generally, negative vs. positive GP88 staining could be applied. We detected 93 patients (47.4%) and 92 patients (46.9%) with GP88-positive TCs or ICs, respectively. The IHC results were correlated with clinicopathological and survival data. Positive GP88 staining in TCs appeared to be an independent poor prognostic factor for disease-specific survival (DSS) (RR (relative risk) = 1.74; p = 0.009) and recurrence-free survival (RFS) (RR = 1.92; p = 0.002). In contrast, negative GP88 staining in ICs was an independent negative predictor for overall survival (OS) (RR = 2.18; p < 0.001), DSS (RR = 2.84; p < 0.001) and RFS (RR = 2.91; p < 0.001) in multivariate Cox’s regression analysis. When combining GP88 staining in TCs and ICs, a specific combination of GP88-positive TCs and GP88-negative ICs was associated with a 2.54-fold increased risk of death, a 4.21-fold increased risk of disease-specific death and a 4.81-fold increased risk of recurrence compared to GP88-negative TCs and GP88-positive ICs. In summary, GP88 positivity in TCs is a negative prognostic factor for DSS and RFS. In addition, GP88 positivity can mark ICs that are associated with a good prognosis (OS, DSS and RFS). The combination of GP88 staining in TCs and ICs appears to be a significant independent prognostic biomarker in muscle-invasive BCa.

Purpose: This study was performed to disclose the clinical impact of isolated tumor cell (ITC) detection in bone marrow (BM) in breast cancer. Patients and Methods: BM aspirates were collected from 817 patients at primary surgery. Tumor cells in BM were detected by immunocytochemistry using anticytokeratin antibodies (AE1/AE3). Analyses of the primary tumor included histologic grading, vascular invasion, and immunohistochemical detection of c-erbB-2, cathepsin D, p53, and estrogen receptor (ER)/progesterone receptor (PgR) expression. These analyses were compared with clinical outcome. The median follow-up was 49 months. Results: ITC were detected in 13.2% of the patients. The detection rate rose with increasing tumor size (P = .011) and lymph node involvement (P < .001). Systemic relapse and death from breast cancer occurred in 31.7% and 26.9% of the BM-positive patients versus 13.7% and 10.9% of BM-negative patients, respectively (P < .001). Analyzing node-positive and node-negative patients separately, ITC positivity was associated with poor prognosis in the node-positive group and in node-negative patients not receiving adjuvant therapy (T1N0). In multivariate analysis, ITC in BM was an independent prognostic factor together with node, tumor, and ER/PgR status, histologic grade, and vascular invasion. In separate analysis of the T1N0 patients, histologic grade was independently associated with both distant disease-free survival (DDFS) and breast cancer–specific survival (BCSS), ITC detection was associated with BCSS, and vascular invasion was associated with DDFS. Conclusion: ITC in BM is an independent predictor of DDFS and BCSS. An unfavorable prognosis was observed for node-positive patients and for node-negative patients not receiving systemic therapy. A combination of several independent prognostic factors can classify subgroups of patients into excellent and high-risk prognosis groups.

A 69-year-old patient treated for infiltrating bladder transitional carcinoma many years ago presented with a submandibular nodule. The last was fortuitously discovered by the patient a month before he presented to consultation. Physical examination showed a firm subcutaneous nodule of 0.5 cm in diameter in the right submandibular region. At this level skin was inflamed/red and swollen. Otherwise physical examination was within normal. The described nodule above was biopsied. Microscopic examination showed infiltration of the dermis by a carcinomatous proliferation (Fig. 1). Tumor cells were arranged in small nests and clusters surrounded by a fibrous stroma. Tumor cells showed moderate nuclear atypia. Immunohistochemical staining showed positivity of tumor cells for Cytokeratin 7 and P63 (Fig. 2). Therefore, taking into consideration patient’s medical history, microscopic and immunohistochemical findings the diagnosis of CM from urothelial carcinoma was retained. The first case of CM from bladder carcinoma was reported in 1909 [3]. Since then many case have been reported [1,2]. According to cases reported in literature so far, the mean interval of time between the setting of bladder cancer and the appearance of CM is of 18 months approximately. Large tumor size and deep infiltration of the bladder wall are predictive factors of CM. However, cases of CM associated with superficial bladder carcinomas were reported [3]. The certain diagnosis is based on microscopic examination [1,3]. Pathologists should be aware of patient’s medical history to facilitate the diagnosis and choosing appropriate immunostains if necessary especially in front of a poorly differentiated carcinoma[3]. Urothelial carcinomas express Cytokeratin 7 and Cytokeratin 20 antibodies [3]. The occurring of CM in case of bladder cancer darken the prognosis [1,2]. Median survival rates are less than 12 months in published cases so far [1,3]. Treatment consists of chemotherapy if the patient could bare it [1]. Total recovery was detected in 70% of cases of CM treated with chemotherapy. Yet, it does not improve global survival rates [3].
