Background: CD24 expression has been described as a significant prognostic factor in multiple solid tumours. Most of these studies have, however, been undertaken using the Ab-2 antibody (clone SN3b), which detects a CD24-associated carbohydrate, and not the CD24 protein itself. Although its biological identity remains unclear, its prognostic significance means that detection of this carbohydrate may, nonetheless, be clinically relevant. Methods: 133 breast carcinomas were selected (pT1-2 pN0-2 M0, no secondary carcinoma, no contralateral carcinoma) from a previous SN3b expression study on a larger cohort of breast carcinomas. After updating data on follow-up observations, we carried out univariate and multivariate analysis of the prognostic significance of SN3b for total and breast cancer-specific survival. Results: A statistically significant correlation between cytoplasmic SN3b immunoreactivity and positive node status was found. Cytoplasmic SN3b also has node status-independent prognostic significance. Total survival exhibits a statistically significant dependency on cytoplasmic SN3b even for pN0 cases. Conclusion: The independent prognostic value of CD24 as detected by Ab-2/clone SN3b could replace the diagnostic axillary dissection in breast carcinoma patients if this was confirmed in further studies. Also, clarifying the exact epitope of this interesting antibody is more than warranted.

Purpose: Estrogen-responsive finger protein (Efp) is amember ofRINGfinger-B box-Coiled Coilfamily and is also a downstream target of estrogen receptor a. Previously, Efp was shown tomediate estrogen-induced cell growth, which suggests possible involvement in the developmentof human breast carcinomas. In this study, we examined expression of Efp in breast carcinomatissues and correlated these findings with various clinicopathologic variables.Experimental Design: Thirty frozen specimens of breast carcinomas were used for immunohistochemistryand laser capture microdissection/real-time PCR of Efp. Immunohistochemistryfor Efp was also done in 151breast carcinoma specimens fixed with formalin and embedded inparaffinwax.Results: Efp immunoreactivity was detected in breast carcinoma cells and was significantlyassociated with the mRNA level (n = 30). Efp immunoreactivity was positively associated withlymph node status or estrogen receptor a status and negatively correlated with histologic gradeor 14-3-3j immunoreactivity (n = 151). Moreover, Efp immunoreactivity was significantly correlatedwith poor prognosis of breast cancer patients, and multivariate analyses of disease-freesurvival and overall survival for151breast cancer patients showed that Efp immunoreactivity wasthe independentmarker.Conclusions: Our data suggest that Efp immunoreactivity is a significant prognostic factor inbreast cancer patients. These findings may account for an oncogenic role of Efp in the tumorprogression of breast carcinoma.

Abstract Background: The efficiency of the T1 sub-staging system on categorizing bladder cancer (BC) patients into subgroups with different clinical outcomes was unclear. We summarized relevant evidences, including recurrence-free survival (RFS), progression-free survival (PFS) and cancer-specific survival (CSS), to analyze the prognostic significance of T1 sub-stage.Methods: Systematic literature searches of MEDLINE, EMBASE and the Cochrane Library were performed. We pooled data on recurrence, progression, and CSS from 35 studies.Results: The pooled hazard ratios (HRs) and 95% confidence intervals (CIs) indicated the difference in RFS between T1a sub-stage and T1b sub-stage (HR1.28, 95%CI 1.14-1.43). The significant difference was observed in PFS between the two arms (HR 2.18, 95%CI 1.95-2.44). Worse CSS was found in T1b patients than T1a patients (HR 1.45, 95%CI 1.28-1.64).Conclusions: T1 sub-staging system based on the invasion depth into muscularis mucosae (MM) can be a significant prognostic factor for RFS, PFS, and CSS of patients with T1-BC. Urologists and pathologists are encouraged to work together to give a precise sub-stage classification of T1-BC, and T1 sub-staging system should be a routine part of any histopathological report when possible. Different treatment strategies need to be developed for both T1a-BC and T1b-BC.

Introduction. To investigate the correlation between preoperative De Ritis ratio (aspartate transaminase (AST)/alanine transaminase (ALT)) and postoperative outcome in patients with urothelial cell carcinoma (UC) treated with radical cystectomy. Materials and Methods. We analyzed the clinical and pathological data of 771 patients who underwent radical cystectomy for bladder UC. Patients were divided into two groups according to the optimal value of AST/ALT ratio. The effect of the AST/ALT ratio was analyzed using the Kaplan–Meier method and Cox regression hazard models for patients’ cancer-specific survival (CSS), overall survival (OS), and recurrence-free survival (RFS). In addition, propensity score matching of 1 : 1 was performed between the two groups. Results. Median follow-up was 84.0 (36–275) months. Mean age was 64.8±10.0 years. According to the receiver operating characteristic (ROC) analysis, the optimal threshold of the AST/ALT ratio was 1.1. In Kaplan–Meier analyses, the high AST/ALT group showed worse outcomes in CSS and OS (all P<0.001). Also, RFS (P=0.001) in the Cox regression models of clinical and pathological parameters was used to predict CSS, OS, and AST/ALT ratio (HR 2.15, 95% CI 1.23-3.73, P=0.007) and pathological T stage (HR 4.80, 95% CI 1.19-19.28, P=0.003). To predict OS and AST/ALT ratio (HR 2.05, 95% CI 1.65–2.56, P<0.001), pathological T stage (HR 2.96, 95% CI 0.57–17.09, P=0.037) and positive lymph node (HR 1.71, 95% CI 1.50–1.91, P=0.021) were determined as independent prognostic factors. Conclusion. Preoperative AST/ALT ratio could be an independent prognostic factor in patients with UC treated with radical cystectomy.

8524 Background: Management of ARL evolved in the last 2 decades. We previously reported prognostic factors in a pooled analysis of 1,546 patients with ARL, and here present analysis of these factors over time to determine if their prognostic significance has changed. Methods: Following a systematic review, we assembled individual patient data from 19 prospective phase 2/3 clinical trials (published 1993-2010) for ARL (n=1,546). Factors analyzed include age, sex, histology, CD4 count, prior history of (h/o) AIDS, & age-adjusted (aa) IPI. The endpoint was overall survival (OS) expressed as the hazard ratio (HR) for death. We used separate Cox proportional hazard models adjusted for the other covariates to determine the significance of each variable in the following time periods: pre-cART [combination antiretroviral therapy] (<1996; n=388), early cART (‘96-‘00; n=694), modern cART (‘01-‘04; n=282) & current era (‘05-‘10; n=182). We also combined all enrollments in one Cox model to test for difference in association with OS over enrollment periods. Results: Rituximab use was limited in the early cART (20%) compared with the modern cART (83%) and current (93%) eras. Histology & sex were not significantly associated with OS in any time period. Increasing age was associated with worse OS in the pre-cART (HR 1.02; p<0.01) and current (HR 1.05, p=0.04) eras. A prior h/o AIDS increased risk of death during early cART (HR 1.31, p=0.047) but was not significant after 2000. Meanwhile, baseline CD4 count <50 was a poor prognostic factor during early (HR 1.78, p<0.01) and modern cART (HR 2.76, p=0.001) eras, but not in the current era. The aaIPI predicted worse OS in each time period (pre-cART: HR 1.54, p<0.0001; early cART: HR 1.49, p<0.0001; modern cART: HR 1.52, p<0.01; current era: HR 2.34, p<0.0001). No significant interaction between each prognostic factor with enrollment was found. Conclusions: In this pooled analysis of 1,546 patients with ARL, aaIPI was the only consistently significant prognostic factor and its effect was magnified in the current era. HIV-related factors gained prognostic relevance in the early and modern cART era but may not be as relevant with current treatment strategies.

Background: The prognostic value of programmed death-ligand 1 (PD-L1) expression in patients with malignant pleural mesothelioma (MPM) has been controversial according to previous investigations. Therefore, we conducted a meta-analysis to assess the potential prognostic significance of PD-L1 expression in MPM. Methods: PubMed, Embase, Web of Science, Scopus, and the Cochrane Library were thoroughly searched for relevant original articles published before 9 April 2020. The pooled hazard ratios (HRs) and 95% confidence intervals (CIs) of overall survival (OS) and progression-free survival (PFS) were calculated. The results of the meta-analysis were verified using The Cancer Genome Atlas (TCGA) dataset. Results: In total 16 studies were included in our meta-analysis. A high PD-L1 expression was associated with a poor OS (HR = 1.53, 95% CI = 1.28–1.83, p < 0.001), but not a grave PFS (HR = 1.07, 95% CI = 0.82–1.39, p = 0.643) in MPM. Furthermore, the PD-L1 expression correlated with the sarcomatoid + biphasic type of MPM (odds ratio = 4.32, 95% CI = 2.16–8.64, p < 0.001). TCGA data indicated that PD-L1 was a significant prognostic factor for OS (HR = 2.069, 95% CI = 1.136–3.769, p = 0.0175), but not for PFS (HR = 1.205, 95% CI = 0.572–2.539, p = 0.624), which was in accordance with the results of the meta-analysis. Conclusion: A high PD-L1 expression is a significant prognostic factor for poor OS of patients with MPM. We therefore suggest that PD-L1 expression levels can be used to predict the clinical outcomes of patients with MPM in the future.
