Purpose The clinical features, pathogenesis, and outcomes in children with adrenocortical tumors (ACTs) without germline TP53 mutations have not been systematically studied. Herein, we describe these correlates and analyze their association with outcome. Patients and Methods Genomic DNA was analyzed for TP53, CTNNB1, CDKN1C, ATRX, and chromosome 11p15 abnormalities. β-catenin expression and Ki-67 labeling index (LI) were evaluated by immunostaining. Primary end points were progression-free (PFS) and overall survival. Results Median age of 42 girls and 18 boys was 3.3 years (range, 0.25 to 21.7 years). Complete resection (stages I and II) was achieved in 32 patients, and 28 patients had stage III or IV disease. Constitutional abnormalities of chromosome 11p15 occurred in nine of 40 patients, with six patients not showing phenotype of Beckwith-Wiedemann syndrome. Three-year PFS and overall survival for all patients were 71.4% and 80.5%, respectively. In single-predictor Cox regression analysis, age, disease stage, tumor weight, somatic TP53 mutations, and Ki-67 LI were associated with prognosis. Ki-67 LI and age remained significantly associated with PFS after adjusting for stage and tumor weight. Three-year PFS for 27 patients with Ki-67 LI ≥ 15% was 48.5% compared with 96.2% for 29 patients with Ki-67 LI < 15% (log-rank P = .002), and the rate of relapse increased by 24% with each 1-year increase in age at diagnosis (hazard ratio, 1.24; P = .0057). Conclusion Clinicopathologic features and outcomes of children with ACTs without germline TP53 mutations overlapped those reported for children with germline TP53 mutations. Our findings highlight the central role of genetic or epigenetic alterations on chromosome 11p15 in pediatric ACTs. Ki-67 LI is a strong prognostic indicator and should be investigated to improve the histologic classification of pediatric ACTs.

Background This study aimed to evaluate the correlation between neutrophil to lymphocyte ratio (NLR) with overall survival (OS) of esophageal squamous cell carcinoma (ESCC) patients. Method Records of patients with diagnosed ESCC were reviewed. Leukocyte counts and patients' characteristics were extracted from their clinical records to calculate NLR. Correlation between NLR and baseline characteristics with overall survival (OS) was then analyzed using Cox regression. The patients were then separated into higher and lower NLR groups according to median NLR. OS was further compared between the 2 groups. Results A total of 1281 patients were included in the study. Cox regression analysis showed a significant correlation of NLR with OS of ESCC patients. The median pretreatment NLR was identified as 2.86. Higher NLR was associated with worse prognosis in terms of OS. Conclusions Pretreatment NLR is independently associated with OS of ESCC patients. Therefore, NLR may be used as a predictive indicator for pretreatment evaluation and adjustment of treatment regimen.

Abstract Background. As a rare primary bone tumour, no studies have reported the relationship between prognosis and marital status in patients with chordoma.Methods. We classified patients with chordoma identified from the Surveillance, Epidemiology, and End Results (SEER) database from 1975 to 2016 into four groups: married, divorced/separated, widowed and single groups. Kaplan-Meier curves with log-rank test and Cox regression were used to analyse the effect of marital status on overall survival (OS).Results. A total of 1,080 patients were included in the study: 700 (64.8%) were married, 88 (8.1%) were divorced/separated, 78 (7.2%) were widowed, and 214 (19.8%) were single. Among the four groups, the 5-year OS (45.2%), 10-year OS (12.5%) and median OS (56.0 months) were the lowest in the widowed group. After including age, sex, primary site, marital status, disease stage, tumor size, histological type, and treatment pattern, multivariate analysis showed that marital status was still an independent risk factor for patients with chordoma, and widowed patients had the lowest OS (hazard ratio [HR]: 1.71; 95% confidence interval [CI]: 1.25–2.33, p<0.001) compared with married patients. Similar results were observed after stratifying the primary site and disease stage.Conclusion. Marital status was an independent prognostic indicator for adult patients with chordoma, and marital status was conducive to patient survival. Compared with married patients, widowed patients have a higher risk of death.

Abstract Aim: To explore the prognostic value of clusterin (CLU) in hepatocellular carcinoma (HCC) patients treated with oxaliplatin (OXA). Methods: Relative expression of plasma CLU mRNA was examined via fluorescence quantitative real-time PCR (qRT-PCR), and CLU protein level in tissue samples was detected through immunohistochemistry. Chi-square test was used to analyze the relationship between CLU mRNA expression and clinical features of HCC patients treated with OXA. Kaplan–Meier method was performed to assess overall survival for the patients, and prognostic value of CLU in HCC patients was estimated via Cox regression analysis. Results: CLU expression in plasma and tissue specimens was significantly higher among HCC patients than in non-malignant controls (P &lt; 0.001 for both). Moreover, elevated CLU mRNA was closely related to tumor stage, lymph node metastasis and response to OXA (P &lt; 0.05). HCC patients with high CLU expression showed poor response to OXA. In addition, low CLU levels predicted long overall survival time among the study subjects (20.8 vs. 36.6 months, P &lt; 0.001). CLU was an independent prognostic indicator for HCC patients treated with OXA (HR = 2.587, 95%CI = 1.749–3.828, P &lt; 0.001). Conclusion: CLU may be a novel prognostic marker for HCC patients treated with OXA.

444 Background: Our aim was to clarify whether the duration between perioperative chemotherapy and disease recurrence could affect therapeutic efficacy of salvage chemotherapy in bladder cancer patients treated with radical cystectomy. Methods: We retrospectively identified 201 patients treated with radical cystectomy and perioperative chemotherapy of neoadjuvant chemotherapy (NAC) and/or adjuvant chemotherapy (AC) for bladder cancer at our 7 institutions between 2003 and 2015. Of them 56 patients received salvage chemotherapy for disease recurrence and were included in the present analysis. We classified these patients according to the time from perioperative chemotherapy received to disease recurrence ( < 12 months, 12-24 months, and 24 < months) and compared their clinical characteristics and survival outcomes. Results: Overall, 33, 14, and 9 patients developed disease recurrence in < 12 months, 12-24 months, and < 24 months, respectively after perioperative chemotherapy. Patients in the 12-24 months group had a higher smoking rate compared to those in the other two groups, and were higher rate of female in comparison to the < 24 months group. Twenty-four (42.8%) patients received NAC alone, 23 (41.1%) received AC alone, and 9 (16.1%) received both NAC and AC. Twenty-two (66.7%), 9 (64%), and 4 (44.4%) patients received NAC in the < 12 months group, the 12-24 months group, and the < 24 months group, respectively. Furthermore, 19 (57.6%), 7 (50%), and 6 (66.7%) patients received AC in the < 12 months group, the 12-24 months group, and the < 24 months group, respectively. The 5 year overall survival in the < 12 months group was 26.6%, which was significantly lower than those in the 12-24 months group (51.1%, p < 0.001) and in the 24 months group (46.9%, p = 0.014). Multivariate Cox regression analysis revealed that disease recurrence after perioperative chemotherapy within 12 months was the only independent prognostic indicator for overall death (p = 0.032). Conclusions: Bladder cancer patients with disease recurrence within 12 months from their perioperative chemotherapy have a worse overall survival after salvage chemotherapy.

COL17A1 (collagen type XVII alpha 1 chain) is known to be upregulated and has a prognostic role in many malignancies, as well as contributing to cell proliferation, apoptosis, and invasion. However, little knowledge is available on the expression and prognostic value of COL17A1 in pancreatic adenocarcinoma (PDAC). In our study, we searched the public database and found that mRNA and protein levels of COL17A1 are commonly upregulated in PDAC tissues. The immunohistochemical analysis conducted by us revealed enhanced expression of COL17A1 protein in 169 PDAC samples compared with that in 67 adjacent normal tissues. We also observed a significantly positive correlation between COL17A1 expression and lymph node metastasis ( p < 0.0001 ), TNM clinical stage ( p < 0.0001 ), and pathology differentiation ( p < 0.01 ). The KM-plot results indicated that PDAC patients with a high COL17A1 expression have a poorer overall survival ( p < 0.001 ) than those with a low COL17A1 expression. The result of the Cox regression analysis of multivariate data suggested COL17A1 is an independent prognostic indicator of PDAC patients’ overall survival. CCK-8, wound healing, and transwell assays suggested that COL17A1 knockdown markedly inhibited tumor proliferation and invasion in PDAC cells, and cells with COL17A1 overexpression had a prominently higher proliferative and invasive capacity. Knockdown of COL17A1 significantly upregulated the apoptosis rate. We deduce that upregulated COL17A1 activated the NF-κB pathway in PDAC cells. In summary, our studies showed the prognostic value of COL17A1 in PDAC and that COL17A1 may act as a molecular therapeutic target for PDAC treatment.

Similar results were observed after stratifying the primary site and disease stage. Conclusion. Marital status was an independent prognostic indicator for adult chordoma patients, and marital status was conducive to patient survival. Compared with married patients, widowed patients have a higher risk of death.

Abstract Background Bridge to elective surgery (BTS) using self-expanding metal stents (SEMSs) is a common alternative to emergency surgery (ES) for acute malignant left-sided colonic obstruction (AMLCO). However, studies regarding the long-term impact of BTS are limited and have reported unclear results. Methods A multicenter observational study was performed at three hospitals from April 2012 to December 2019. Propensity score matching (PSM) was introduced to minimize selection bias. The primary endpoint was overall survival. The secondary endpoints included surgical approaches, primary resection types, total stent-related adverse effects (AEs), surgical AEs, length of hospital stay, 30-day mortality and tumor recurrence. Results Forty-nine patients in both the BTS and ES groups were matched. Patients in the BTS group more often underwent laparoscopic resection [31 (63.3%) vs. 8 (16.3%), p < 0.001], were less likely to have a primary stoma [13 (26.5%) vs. 26 (53.1%), p = 0.007] and more often had perineural invasion [25 (51.0 %) vs. 13 (26.5 %), p = 0.013]. The median overall survival was significantly lower in patients with stent insertion (41 vs. 65 months, p = 0.041). The 3-year overall survival (53.0 vs. 77.2%, p = 0.039) and 5-year overall survival (30.6 vs. 55.0%, p = 0.025) were significantly less favorable in the BTS group. In multivariate Cox regression analysis, stenting (hazard ratio(HR) = 2.309(1.052–5.066), p = 0.037), surgical AEs (HR = 1.394 (1.053–1.845), p = 0.020) and pTNM stage (HR = 1.706 (1.116–2.607), p = 0.014) were positively correlated with overall survival in matched patients. Conclusions Self-expanding metal stents as “a bridge to surgery” are associated with more perineural invasion, a higher recurrence rate and worse overall survival in patients with acute malignant left-sided colonic obstruction compared with emergency surgery.

De novo cases of metastatic prostate cancer (mCSPC) are associated with poorer prognosis. To assist in clinical decision-making, we aimed to determine the prognostic utility of commonly available laboratory-based markers with overall survival (OS). In a retrospective population-based study, a cohort of 3556 men aged ≥66 years diagnosed with de novo mCSPC between 2014 and 2019 was identified in Ontario (Canada) administrative database. OS was assessed by using the Kaplan–Meier method. Multivariate Cox regression analysis was performed to evaluate the association between laboratory markers and OS adjusting for patient and disease characteristics. Laboratory markers that were assessed include neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), albumin, hemoglobin, serum testosterone and PSA kinetics. Among the 3556 older men with de novo mCSPC, their median age was 77 years (IQR: 71–83). The median survival was 18 months (IQR: 10–31). In multivariate analysis, a statistically significant association with OS was observed with all the markers (NLR, PLR, albumin, hemoglobin, PSA decrease, reaching PSA nadir and a 50% PSA decline), except for testosterone levels. Our findings support the use of markers of systemic inflammation (NLR, PLR and albumin), hemoglobin and PSA metrics as prognostic indicators for OS in de novo mCSPC.

Abstract Introduction Angiogenesis is a key factor in promoting tumor growth, invasion and metastasis. In this study we aimed to investigate the prognostic value of angiogenesis-related genes (ARGs) in gastric cancer (GC). Methods mRNA sequencing data with clinical information of GC were downloaded from The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) databases. The differentially expressed ARGs between normal and tumor tissues were analyzed by limma package, and then prognosis‑associated genes were screened using Cox regression analysis. Nine angiogenesis genes were identified as crucially related to the overall survival (OS) of patients through least absolute shrinkage and selection operator (LASSO) regression. The prognostic model and corresponding nomograms were establish based on 9 ARGs and verified in in both TCGA and GEO GC cohorts respectively. Results Eighty-five differentially expressed ARGs and their enriched pathways were confirmed. Significant enrichment analysis revealed that ARGs-related signaling pathway genes were highly related to tumor angiogenesis development. Kaplan–Meier analysis revealed that patients in the high-risk group had worse OS rates compared with the low-risk group in training cohort and validation cohort. In addition, RS had a good prognostic effect on GC patients with different clinical features, especially those with advanced GC. Besides, the calibration curves verified fine concordance between the nomogram prediction model and actual observation. Conclusions We developed a nine gene signature related to the angiogenesis that can predict overall survival for GC. It’s assumed to be a valuable prognosis model with high efficiency, providing new perspectives in targeted therapy.

INTRODUCTION The extensive use of prostate-specific antigen as a general prostate cancer biomarker has introduced the hazards of overdiagnosis and overtreatment. Recent studies have revealed the immense biomarker capacity of microRNAs (miRNAs) in prostate cancer. The aim of this study was to analyze the expression pattern of miR-224, a cancer-related miRNA, in prostate tumors and investigate its clinical utility. METHODS Total RNA was isolated from 139 prostate tissue samples. After the polyadenylation of total RNA by poly(A) polymerase, cDNA was synthesized with a suitable poly(T) adapter. miR-224 expression was assessed by quantitative real-time PCR and analyzed with the comparative quantification cycle method, Cq(2−ΔΔCq). We performed comprehensive biostatistical analyses to explore the clinical value of miR-224 in prostate cancer. RESULTS miR-224 expression was significantly downregulated in malignant samples compared with benign samples (P &lt; 0.001). Higher miR-224 expression levels were found in prostate tumors that were less aggressive (P = 0.017) and in an earlier disease stage (P = 0.018). Patients with prostate cancer who were positive for miR-224 had significantly enhanced progression-free survival intervals compared with miR-224–negative patients (P = 0.021). Univariate bootstrap Cox regression confirmed that miR-224 was associated with favorable prognosis (hazard ratio 0.314, P = 0.013); nonetheless, multivariate analysis, adjusted for conventional markers, did not identify miR-224 as an independent prognostic indicator. CONCLUSIONS miR-224 is aberrantly expressed in prostate cancer. Its assessment by cost-effective quantitative molecular methodologies could provide a useful biomarker for prostate cancer.
