Moreover, Cα space-filling model may simulate dynamic change of protein folding conformation at atomic level. Insight into the key genes of pluripotency in human and their interrelationships is necessary for understanding the underlying mechanism of pluripotency and hence their successful application in regenerative medicine. The recent advances in transcriptomics technologies have created new opportunities to decipher the genes involved in pluripotency, genetic network that governs the unique properties of embryonic stem cells and lineage differentiation mechanisms in a deeper scale. There are a large number of experimental studies on human embryonic stem cells (hESCs) being routinely conducted for unfolding the underlying biology of embryogenesis and their clinical prospects. However, the outcome of these studies often lacks consensus due to differences in samples, experimental techniques and/or analysis protocols. A universal stemness gene list is still lacking. Thus, we aim to identify the pluripotency-associated genes and their interaction network. In this quest, we compared transcriptomic profiles of pluripotent and non-pluripotent samples from diverse cell lines/types generated through RNA-sequencing (RNA-seq). We used a uniform pipeline for the analysis of raw RNA-seq data in order to reduce the amount of variation. Our analysis revealed a consensus set of 498 pluripotency-associated genes and 432 genes as potential pluripotent cell differentiation markers. Furthermore, we predicted 32 genes as "pluripotency critical genes". These pluripotency critical genes formed a tightly bound co-expression network with small-world architecture. Gene ontology (GO) and pathway enrichment analysis, StemChecker and literature survey confirmed the involvement of the genes in the induction and maintenance of pluripotency, though more experimental studies are required for understanding their molecular mechanisms in human. BACKGROUND Concurrent chemoradiotherapy is the standard treatment for anal cancer. Following national UK implementation of intensity-modulated radiotherapy (IMRT), this prospective, national cohort evaluates the one-year oncological outcomes and patient-reported toxicity outcomes (PRO) after treatment. MATERIALS AND METHODS A national cohort of UK cancer centers implementing IMRT was carried out between February to July 2015. Cancer centers provided data on oncological outcomes, including survival, and disease and colostomy status at one-year. EORTC-QLQ core (C30) and colorectal (CR29) questionnaires were completed at baseline and one-year followup. The PRO scores at baseline and one year were compared. RESULTS 40 UK Cancer Centers returned data with a total of 187 patients included in the analysis. 92% received mitomycin with 5-fluorouracil or capecitabine. One-year overall survival was 94%; 84% were disease-free and 86% colostomy-free at one-year followup. At one year, PRO results found significant improvements in buttock pain, blood and mucus in stools, pain, constipation, appetite loss, and health anxiety compared to baseline. No significant deteriorations were reported in diarrhea, bowel frequency, and flatulence. Urinary symptom scores were low at one year. Moderate impotence symptoms at baseline remained at one year, and a moderate deterioration in dyspareunia reported. CONCLUSIONS With national anal cancer IMRT implementation, at this early pre-defined time point, one-year oncological outcomes were reassuring and resulted in good disease-related symptom control. one-year symptomatic complications following CRT for anal cancer using IMRT techniques appear to be relatively mild. These PRO results provide a basis to benchmark future studies. AIM Lately, the safety of minimally invasive surgery (MIS) in the treatment of cervical cancer (CC) has been questioned. This study aimed to evaluate the risk of recurrence and survival after a nationwide adoption of robotic MIS for the treatment of early-stage CC in Denmark. METHODS Population-based data on all Danish women with early-stage CC, who underwent radical hysterectomy January 1st 2005-June 30th 2017 were retrieved from the Danish Gynecologic Cancer Database and enriched with follow-up data on recurrence, death and cause of death. The cohort was divided into two groups according to the year of robotic MIS introduction at each cancer centre. Chi-squared or Fischer test, the Kaplan Meier method and multivariate Cox regression were used for comparison between groups. RESULTS One thousand one hundred twenty-five patients with CC were included; 530 underwent surgery before (group 1) and 595 underwent surgery after (group 2) the introduction of robotic MIS. The 5-year rate of recurrence was low 8.2% and 6.3% (p = 0.55) in group 1 and 2, respectively. In adjusted analyses, this corresponded to a five-year disease-free survival, hazard ratio (HR) 1.23 [95% confidence interval (CI) 0.79-1.93]. No difference in site of recurrence (P = 0.19) was observed. The cumulative cancer-specific survival was 94.1% and 95.9% (P = 0.10) in group 1 and 2, respectively, corresponding to a HR 0.60 [95% CI 0.32-1.11] in adjusted analyses. CONCLUSION In this population-based cohort study, the Danish nationwide adoption of robotic MIS for early-stage CC was not associated with increased risk of recurrence or reduction in survival outcomes. INTRODUCTION High-risk (HR) metastatic (stage IV) Wilms tumours (WTs) have a particular poor outcome. METHODS Here, we report the results of HR (diffuse anaplastic [DA] or blastemal type [BT]) stage IV WT treated patients according to the HR arm in the SIOP2001 prospective study. RESULTS From January 2002 to August 2014, 3559 patients with WT were included in the SIOP2001 trial. Among the 525 patients (15%) with metastatic WT, 74 (14%) had stage IV HR-WT. The median age at diagnosis was 5.5 years (range 1.4-18.3). Thirty-four patients (47%) had BT-WT and 40 (53%) had DA-WT. Five-year event-free survival rates were 44 ± 17% and 28 ± 15% for BT-WT and DA-WT, respectively (p = 0.09). Five-year overall survival rates were 53 ± 17% and 29 ± 16% for BT-WT and DA-WT, respectively (p = 0.03). Metastatic complete response after preoperative treatment was significantly associated with outcome in univariate and multivariate analyses (hazards ratio = 0.3; p = 0.01). Postoperative radiotherapy of metastatic sites might also be beneficial. Forty-three of 74 patients experienced a relapse or progression predominantly in the lungs (80%). The median time to relapse/progression after diagnosis was 7.3 months (range 1.6-33.3) and 4.9 months (range 0.7-28.4) for BT-WT and DA-WT, respectively (p = 0.67). This is the first prospective evidence of inferior survival of stage IV BT-WT as compared with historical intermediate-risk WT. Survival of patients with stage IV DA-WT has not improved compared to the previous SIOP93-01 study. CONCLUSION These results call for new treatment approaches for patients with HR stage IV WT. AIM Tumour-associated macrophages (TAMs) are prominent immune cells infiltrating in solid tumours with phenotypic and functional heterogeneity. However, the clinical significance of heterogeneous subtypes of TAMs in gastric cancer still remains obscure. Here, we aimed to explore the clinical significance of TAMs expressing dendritic cell-specific intercellular adhesion molecule 3-grabbing non-integrin (DC-SIGN) and its relevance with immune contexture in gastric cancer. METHODS We selected 453 formalin-fixed and paraffin-embedded samples and 51 fresh tissue specimens of patients with gastric cancer from Zhongshan Hospital. The association of DC-SIGN+ macrophages with clinicopathological parameters, overall survival (OS) and responsiveness to fluorouracil-based adjuvant chemotherapy (ACT) was inspected. Immunohistochemistry (IHC) and flow cytometry (FCM) were applied to characterize immune cells in gastric cancer. RESULTS We demonstrated that high intratumoral DC-SIGN+ macrophages infiltration predicted poor OS and inferior therapeutic responsiveness to fluorouracil-based ACT in patients with gastric cancer. Furthermore, higher infiltration of DC-SIGN+ macrophages indicated an increased number of Foxp3+ regulatory T cells (Tregs), CD8+ T cells and a higher ratio of Foxp3+/CD8+ within the tumour microenvironment (TME). In addition, CD8+ T cells in DC-SIGN+ macrophages high subgroup were functionally impaired, showing decreased interferon-γ (IFN-γ), granzyme B (GZMB) and perforin production yet elevated programmed cell death protein 1 (PD-1) and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) expression. CONCLUSIONS DC-SIGN+ macrophages were associated with immunoinvasive TME and indicated poor prognosis and inferior therapeutic responsiveness to fluorouracil-based ACT. DC-SIGN+ macrophages might be an independent prognosticator and a potential immunotherapeutic target for gastric cancer. BACKGROUND Several studies have found an association between higher body mass index (BMI) and improved clinical outcomes in cancer patients receiving programmed cell death protein-1 (PD-1)/programmed cell death-ligand 1 (PD-L1) checkpoint inhibitors. In a previous study, we found that overweight/obese patients were significantly more likely to experience any grade immune-related adverse events (irAEs) compared to non-overweight patients. PATIENTS AND METHODS We conducted a 'real-life', multi centre, retrospective observational study aimed at comparing the incidence of irAEs among cancer patients treated with PD-1/PD-L1 inhibitors according to baseline BMI. RESULTS One thousand and seventy advanced cancer patients were evaluated. The median age was 68 years (range 21-92), male/female ratio was 724/346. Primary tumours were non-small-cell lung carcinoma (NSCLC) (653 patients), melanoma (233 patients), renal cell carcinoma (RCC) (152 patients) and others (29 patients). Median BMI was 25 (13.6-46.6); according tocutaneous, endocrine, gastro-intestinal (GI), hepatic and 'others' irAEs, compared to normal-weight patients. learn more Only obese patients experienced a significantly higher occurrence of pulmonary and rheumatic irAEs, compared to normal-weight patients. CONCLUSIONS Considering the previously evidenced association between higher BMI and better outcome, the current finding about the relationship between BMI and irAEs occurrence can contribute to consideration of these findings as the upside of the downside, which underlies an 'immunogenic phenotype'. Rectal cancer can spread in a number of ways which have been previously recognised and validated as prognostic markers. These routes of spread are not adequately recognised in the stage grouping of the tumour-node-metastasis system, which focuses predominantly on the depth of invasion and nodal status, thus limiting its prognostic accuracy. Tumour spread involving veins occurs in 40% of patients. Venous channels have greater direct access to distant sites by means of a vascular 'anatomical highway'. This rapid spread of tumour cells to distant metastatic sites by veins cannot occur by means of lymph node pathways. Thus, lymph nodes have been overestimated in their importance. Distinction between local tumour spread (lymph node metastases, perineural and lymphatic invasion) and tumour spread mediated by a direct vascular pathway to distant dissemination (extramural venous invasion and tumour deposits) must be made as the implications for prognosis and choice of treatment are not likely to be equal. Improved precision of radiological and pathological assessment is needed to scrutinise and carefully document each route of tumour spread.
