Purpose The purpose of the paper is to contribute to further advancing of IMP as a research field by setting up and starting a theoretical conversation between system theory and the IMP. Design/methodology/approach The approach is based on a narrative literature study and conceptual research. Findings The authors find that system theory and cybernetics can be regarded as important sources of inspiration for early IMP research. The authors identify three specific theoretical “puzzles” in system theory that may serve as useful topics for discussion between system theorists and IMP researchers. Originality/value Only a handful of papers have touched upon the relationship between system theory and IMP before. This paper combines a narrative, historical analysis of this relationship with developing specific suggestions for using system theory as a vehicle for further advancement of IMP research.

Abstract Background Colon cancer (CC) is one of the most common gastrointestinal malignant tumors with high mortality rate. Because of malignancy and easily metastasis feather, and limited treatments, the prognosis of CC remains poor. Glycolysis is a metabolic process of glucose in anoxic environments which is an important way to provide energy for tumor. The role of glycolysis in CC largely remains unknown and is necessary to be explored. Method In our study, we analyzed glycolysis related genes expression in CC, patients gene expression and corresponding clinical data were downloaded from GEO dataset, glycolysis related genes sets were collected from Msigdb. Through COX regression analysis, prognosis model based on glycolysis-related genes was established. The efficacy of gene model was tested by Survival analysis, ROC analysis and PCA analysis. Furthermore, the relationship between risk scores and clinical characteristic was researched. Results Our findings identified 13 glycolysis related genes (NUP107, SEC13, ALDH7A1, ALG1, CHPF, FAM162A, FBP2, GALK1, IDH1, TGFA, VLDLR, XYLT2 and OGDHL) consisted prognostic prediction model with relative high accuracy. The relationship between prediction model and clinical feathers were specifically studied, results showed age > 65years, TNM III-IV, T3-4, N1-3, M1 and high-risk score were independent prognostic risk factors with poorer prognosis. Finally, model genes were significantly expressed and EMT were activated in CC patients. Conclusion This study provided a new aspect to advance our understanding in the potential mechanism of glycolysis in CC.

Abstract Introduction. Soft tissue sarcomas (STS) are rare entities of soft tissue cancers. Their incidence is low, of only 1% of the malignant tumors. In terms of localization, most of the STS affect the extremities, and their incidence is much higher in children than in adults. Material and method. The present paper is a retrospective study that includes tumors with lower limb localizations, including the bony pelvis, over a 3-year period (2013-2016). The study group consisted of 29 patients who, following the MRI examination, were diagnosed with softtissue tumors. Of the 29 patients, 17 patients had a MRI (magnetic resonance imaging) and an anatomopathological diagnosis of leiomyosarcoma. The location of the tumor, its characteristics, and the relationship with the adjacent anatomical structures were analyzed in all cases. Results. The ages of the final group of 17 patients ranged between 28 and 84 years, with female predominance. In terms of localization, one showed a muscle tumor in the pelvis, namely left oblique muscle, other cases being located in the thigh and knee. A special importance was given to the superficial and profound location. In 5 cases, the tumor was localized in subcutaneous fatty tissue, thus superficial. In terms of the contours of the tumor, well-defined margins were present in 11 cases, and poorly defined contour in 6 cases. Regarding the size, the leiomyosarcomas in our study had dimensions between 5.2 cm and 18 cm, and their structure was inhomogeneous, with the presence of necrosis and calcifications. Necrosis was found in 14 cases, and calcifications were present in 68%, being more frequent than necrosis. Except for the necrotic areas, the contrast enhancement was intense. Conclusions. Although the diagnosis is always histopathological, the MRI plays an important role in defining a precise localization and tumor characteristics.

Tissue hypoxia is a common and important feature of rapidly growing malignant tumors and their metastases. Tumor cells mainly depend on energy production thru anaerobic glycolysis rather than aerobic oxidative phosphorylation in mitochondria [1]. Intervening the tumor metabolic process via thermal energy infusion is worthy attempting. And hyperthermia, mildly elevated local temperature above the body temperature, is one of such kind. Previously, after being heated for a short period of time, tumor glucose and lactate level increased and ATP level decreased, which suggested energy metabolism was modified following hyperthermia through increased ATP hydrolysis, intensified glycolysis and impaired oxidative phosphorylation [2]. Many researchers designed experiments to determine thermal dose in hyperthermia [3], but few focused on the relationship between tumor and energy, especially for a long-term local hyperthermia treatment. One clinical trial indicated the effective long-term hyperthermo-therapy for maintaining performance status, symptomatic improvement, and prolongation of survival time in patients with peritoneal dissemination [4].

Abstract Several studies have been conducted to determine the relationship between post-treatment total lymphocyte count (TLC) and overall survival (OS) in patients with malignant tumors including glioblastomas (GBMs). In this retrospective study, whether patients with newly diagnosed GBM experience significant lymphopenia after concomitant chemoradiation (CCRT) was evaluated, and whether TLC after this treatment is associated with OS in the treated population was examined. Using electronic medical records, all patients newly diagnosed with GBM between 2008 and 2016 at Seoul St. Mary’s Hospital were retrospectively examined. The eligible criteria included the following: 1) craniotomy with surgical resection or biopsy, 2) completion of CCRT, 3) accessible baseline and/or follow-up complete blood count (CBC). Median TLC significantly decreased after completion of CCRT, compared to TLC at baseline (1,742 versus 1,319 cells/mm3, P-value < 0.001). Patients with TLC < 1,200 cells/mm3 at 4 weeks after the completion of CCRT showed shorter survival than those with TLC ≥ 1,200 cells/mm3 with median OS of 14.5 versus 21.0 months (P-value = 0.017). Also, in multivariate analysis for OS, TLC < 1,200 cells/mm3 at 4 weeks after the completion of CCRT (HR 1.97, 95% CI 1.61 – 2.25, P-value = 0.004) were significantly associated with shorter survival. The results from the present study indicate that treatment-related total lymphocyte counts after CCRT is associated with worse survival in patients with newly diagnosed GBM.

ABSTRACT Introduction: Hepatocellular carcinoma is one of the most frequent types of malignant tumors in the world. There is growing evidence of the relationship between it development and obesity. The mechanism that links obesity to cancer is still not fully understood; however, it is essential to the understanding the adipose tissue in metabolic changes related to obesity and hepatocellular carcinoma. Objective: To review the influence of serum leptin levels in patients with hepatocelular carcinoma. Method: Systematic review of the literature based on the methodology of the Cochrane Institute. The search for articles was in the database: Science Direct, Scielo, Medline, Lilacs e Pubmed. The key words used were hepatocellular carcinoma, leptin, adipokine. Results: After evaluation of individual studies, were selected seven studies. The results previously studied are still inconsistent and contradictory, and leptin can be effectively involved in the occurrence and development of hepatocellular carcinoma. Conclusion: Therefore, it is necessary to develop prospective, well-designed and conducted focusing on the role and specific mechanisms of this hormone in patients with hepatocellular carcinoma, so that new correlations can be properly supported.

Abstract Background: Although many biomarkers have been reported for detecting glioma, the prognosis for the disease remains poor, and therefore, new biomarkers need to be identified. GNG5, which is part of the G-protein family, has been associated with different malignant tumors, though the role of GNG5 in glioma has not been studied. Therefore, we aimed to identify the relationship between GNG5 expression and glioma prognosis and to identify a new biomarker for the diagnosis and treatment of gliomas.Methods: We used datasets from databases including TCGA and GEO, and results from GEPIA, RT-qPCR, and HPA to determine the expression of GNG5 in glioma. Based on datasets obtained from the CGGA database, we identified the correlation between GNG5 expression and multiple molecular and clinical features as well as clinical prognosis using a variety of analytical methods. Co-expression analysis and GSEA were performed to detect GNG5-related genes in gliomas and possible signaling pathways involved. ESTIMATE, ssGSEA, and TIMER were used to detect the relationship between GNG5 and the immune microenvironment.Results: A total of 1826 glioma related datasets were used in our study, including sequencing data, microarray data, and RT-qPCR data. We found that GNG5 is highly expressed in gliomas, and its expression level is positively correlated with pathological grade, histological type, age, and tumor recurrence and negatively correlated with isocitrate dehydrogenase mutation, 1p/19 co-deletion, and chemotherapy. Moreover, GNG5 as an independent risk factor was negatively correlated with the overall survival time. GSEA analysis revealed the potential signaling pathways involved in GNG5 function in gliomas, such as ECM-receptor interaction and the toll-like receptor signaling pathway. The ssGSEA, ESTIMATE, and TIMER based analysis indicated a correlation between GNG5 expression and various immune cells in glioma, such as B cell, macrophage, and dendritic cells.Conclusions: Based on the large data platform and the use of different databases to corroborate results obtained using various datasets, our study reveals for the first time that GNG5, as an oncogene, is overexpressed in gliomas and can lead to poor prognosis of patients. Thus, GNG5 is a potential novel biomarker for the clinical diagnosis and treatment of gliomas.
