BackgroundPeople’s Republic of China is one of the countries with the highest incidence of gastric cancer, accounting for 45% of all new gastric cancer cases in the world. Therefore, strong prognostic markers are critical for the diagnosis and survival of Chinese patients suffering from gastric cancer. Recent studies have begun to unravel the mechanisms linking the host inflammatory response to tumor growth, invasion and metastasis in gastric cancers. Based on this relationship between inflammation and cancer progression, several inflammation-based scores have been demonstrated to have prognostic value in many types of malignant solid tumors.ObjectiveTo compare the prognostic value of inflammation-based prognostic scores and tumor node metastasis (TNM) stage in patients undergoing gastric cancer resection.MethodsThe inflammation-based prognostic scores were calculated for 207 patients with gastric cancer who underwent surgery. Glasgow prognostic score (GPS), neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), prognostic nutritional index (PNI), and prognostic index (PI) were analyzed. Linear trend chi-square test, likelihood ratio chi-square test, and receiver operating characteristic were performed to compare the prognostic value of the selected scores and TNM stage.ResultsIn univariate analysis, preoperative serum C-reactive protein (P<0.001), serum albumin (P<0.001), GPS (P<0.001), PLR (P=0.002), NLR (P<0.001), PI (P<0.001), PNI (P<0.001), and TNM stage (P<0.001) were significantly associated with both overall survival and disease-free survival of patients with gastric cancer. In multivariate analysis, GPS (P=0.024), NLR (P=0.012), PI (P=0.001), TNM stage (P<0.001), and degree of differentiation (P=0.002) were independent predictors of gastric cancer survival. GPS and TNM stage had a comparable prognostic value and higher linear trend chi-square value, likelihood ratio chi-square value, and larger area under the receiver operating characteristic curve as compared to other inflammation-based prognostic scores.ConclusionThe present study indicates that preoperative GPS and TNM stage are robust predictors of gastric cancer survival as compared to NLR, PLR, PI, and PNI in patients undergoing tumor resection.

Abstract. High Glasgow Prognostic Score (GPS) has been associated with poor prognosis in patients with lung, ovarian, colorectal and renal cancer, as well as hepatocellular carcinoma. The aim of this study was to investigate the prognostic value of GPS in patients with intrahepatic cholangiocarcinoma (ICC) undergoing partial hepatectomy. A total of 72 patients with pathologically confirmed ICC were classified according to their GPS scores assigned based on the preoperative levels of C-reactive protein (CRP) and albumin. Their clinicopathological data were retrospectively assessed using univariate and multivariate analysis to determine their association with overall survival and recurrence. High GPS scores in ICC patients were associated with preoperative levels of CRP (P<0.001) and albumin (P<0.001), frequency of ascites accumulation (P=0.035), lymph node metastasis (P=0.002) and tumour size (P=0.005). On univariate analysis, preoperative levels of CRP (P<0.001), albumin (P=0.016) and carbohydrate antigen 19-9 (P=0.038), hepatitis B virus (HBV) positivity (P=0.009), occurrence of lymph node metastasis (P=0.001), Child-Pugh class B (P=0.013) and high tumour-node-metastasis (TNM) stage (P=0.002) were found to be associated with the 1-and 3-year overall survival. Multivariate analysis suggested that GPS score (HR=2.037, 95% CI: 1.092-3.799, P=0.025), TNM classification (HR=2.000, 95% CI: 1.188-3.367, P=0.009) and HBV positivity (HR=0.559 95% CI: 0.328-0.953, P=0.032) were independently associated with patient survival. High GPS scores also predicted ICC recurrence. In conclusion, our results demonstrated that GPS may serve as an independent marker of prognosis in patients with ICC following partial hepatectomy.

Background: Some prognostic evaluation systems were developed to postoperatively predict the outcome of hepatocellular carcinoma (HCC) patients, mainly based on the cancer itself and the underlying liver diseases. However, none of these prognostic evaluation systems have so far been universally accepted. A simple and feasible scoring system is still lacking for the prediction of prognosis of HCC patients following resection. We aimed to uncover the correlation between the preoperative Glasgow Prognostic Score (GPS) and the clinical outcome of HCC patients after radical resection. Methods: The patients were separated into 3 subgroups on the basis of their GPSs. The prognostic significance of the GPS in the patient cohort was evaluated by survival analysis. Results: On univariate analysis, the levels of C-reactive protein and albumin, the Child-Pugh class, vascular invasion, tumor number, tumor size, the tumor/node/metastasis (TNM) stage, and the GPS were associated with overall survival and time to recurrence of HCC patients after radical resection. On multivariate analysis, the tumor size, albumin level, and GPS were independently associated with the outcome of HCC postoperatively. Conclusion: The GPS is an independent biomarker for prognostic prediction of HCC following radical resection.

A newly-developed platform, integrating subtraction enrichment and immunostaining-fluorescence in situ hybridization (SE-iFISH), was applied to analyze the clinical significance of circulating tumor cells (CTCs) for early screening of cancer in healthy people. The present case report describes one healthy individual who accepted a CTC peripheral blood test, and 8 CTCs/7.5 ml blood were detected. However, various conventional cancer biomarkers were all negative, including cervical cytological inspection, alpha-fetoprotein, cancer antigen (CA)-125, CA19-9, carcinoembryonic antigen (CEA), CA15-3 and human papilloma virus. To explore the origin of the CTCs, whole exome sequencing was used to analyze the CTC variation spectrum. A total of 42 mutations were associated with cancer according to analysis in COSMIC (). The results revealed a high risk of tumor in the colorectum, stomach and breast (13, 12 and 6 variations matched, respectively). In this individual, an intestinal polyp was discovered and removed by colonoscopy. The intestinal polyp was identified to be a hyperplastic polyp by pathological diagnosis. No lesions were discovered in the stomach and breast. No CTCs were detected in this patient's blood at 1 and 6 months after removal of the lesions. This case indicates that CTC detection by SE-iFISH has potential in early stage cancer screening, and the mutation spectrum of CTC assists the tracking of its sources.

Background: The carcinogenesis and prognosis of hepatocellular carcinoma (HCC) involve complex molecular mechanisms, and ferroptosis is related to the development and therapeutic efficacy of HCC, but the specific mechanism and prognostic role of ferroptosis-related genes in HCC have not been elucidated.Methods: Differentially expressed gene analysis, Cox regression, and unsupervised consensus clustering were applied to identify crucial ferroptosis regulators and establish ferroptosis-related subtypes in HCC. Random forest analysis and survival analysis were adopted to confirm FTL as the hub prognostic and diagnostic ferroptosis regulator in HCC.Results: The ferroptosis-related subtypes based on the crucial prognostic ferroptosis regulators showed that patients in fescluster A had a higher survival probability (p &lt; 0.001) and better clinical characteristics than patients in fescluster B in the TCGA-LIHC cohort. Patients with a high tumor mutation burden (TMB) in fescluster B presented a significantly poorer prognosis. FTL was the core ferroptosis regulator, and its low expression revealed a significant survival advantage compared with its high expression (p = 0.03). The expression and predictive value of FTL were both closely related to the clinical features (p &lt; 0.05). Expression of FTL accurately distinguished HCC from normal tissues in the TCGA-LIHC cohort, ICGC cohort, and GSE14520 dataset. In addition, higher infiltrating fractions of immune cells, such as activated CD8+ T cells and Gamma delta T cells, mainly enriched immune-related signaling pathways, including the IL2-STAT3 signaling pathway and interferon-gamma response signaling pathway, and higher expression of immune checkpoints, including PDCD1, CTLA4, TIGIT, and CD83, were presented in patients with high FTL expression (p &lt; 0.05). Patients with high FTL were more sensitive to some targeted drugs, such as cisplatin, dasatinib, and sorafenib, than those with low FTL (p &lt; 0.05). A nomogram based on FTL accurately predicted the prognosis of HCC. Further knockdown of FTL was determined to significantly inhibit cell proliferation and migration in HCC.Conclusion: Our study validated ferroptosis-related subtypes and FTL with effective prognostic value in HCC and was beneficial for identifying candidates suitable for targeted drug therapy and immunotherapy, thereby offering further insight into individual treatment strategies to improve disease outcomes in HCC patients.
