However, most patients cannot benefit from such therapies, mainly due to the intrinsic low immunogenicity of cancer cells (CCs) that allows them to escape recognition by immune cells of the body. Immunogenic cell death (ICD), which is a form of regulated cell death, engages in a complex dialogue between dying CCs and immune cells in the tumor microenvironment (TME), ultimately evoking the damage-associated molecular pattern (DAMP) signals to activate tumor-specific immunity. The ICD inducers mediate the death of CCs and improve both antigenicity and adjuvanticity. At the same time, they reprogram TME with a “cold-warm-hot” immune status, ultimately amplifying and sustaining dendritic cell- and T cell-dependent innate sensing as well as the antitumor immune responses. In this review, we discuss how to stimulate ICD based upon the biological properties of CCs that have evolved under diverse stress conditions. Additionally, we highlight how this dynamic interaction contributes to priming tumor immunogenicity, thereby boosting anticancer immune responses. We believe that a deep understanding of these ICD processes will provide a framework for evaluating its vital role in cancer immunotherapy.","PeriodicalId":9882,"journal":{"name":"Chinese Journal of Cancer Research","volume":"34 1","pages":"1 - 10"},"PeriodicalIF":5.1,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42578044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we aim to update the equivalent efficacy assessment between QL1101 and bevacizumab based on two-year follow-up data. Methods In total, 535 eligible NSCLC patients were enrolled in this randomized controlled trial. Patients were randomly assigned 1:1 to the QL1101 group and the bevacizumab group. The full end time of this study was defined as 24 months after the last enrolled patient was randomized. The primary endpoint was the objective response rate (ORR); equivalence was confirmed if the two-sided 90% confidence interval (90% CI) of the relative risk was within the range of 0.75−1.33. The secondary endpoints were progression-free survival (PFS) and overall survival (OS). Results The two-year updated data showed similar ORR (QL1101 vs. bevacizumab: 53.1% vs. 54.3%; relative risk=0.977; 90% CI: 0.838−1.144), PFS (235 d vs. 254 d, log-rank P=0.311), and OS (577 d vs. 641 d, log-rank P=0.099) results between the QL1101 group and the bevacizumab group. The mean shrinkage ratio of targeted lesions was also similar between the QL1101 group and the bevacizumab group (22.5% vs. 23.5%). For patients who received QL1101 maintenance therapy, similar results were shown between the QL1101 group (n=157) and the bevacizumab group (n=148) (PFS: 253 d vs. 272 d, log-rank P=0.387; OS: 673 d vs. 790 d, log-rank P=0.101; mean tumor shrinkage rate: 26.6% vs. 27.5%).

However, the median progression-free survival (mPFS) of 4-1BB-based product Kymriah was shorter than that of CD28-based Yescarta (2.9 monthsvs. 5.9 months), suggesting that Kymriah was limited in the long-term efficacy. Thus, a safe and durable 4-1BB-based CD19 CAR-T needs to be developed. Methods We designed a CD19-targeted CAR-T (named as IM19) which consisted of an FMC63 scFv, 4-1BB and CD3ζ intracellular domain and was manufactured into a memory T-enriched formulation. A phase I/II clinical trial was launched to evaluate the clinical outcomes of IM19 in relapsed or refractory (r/r) B cell non-Hodgkin lymphoma (B-NHL). Dose-escalation investigation (at a dose of 5×105/kg, 1×106/kg and 3×106/kg) was performed in 22 r/r B-NHL patients. All patients received a single infusion of IM19 after 3-day conditional regimen. Results At month 3, the overall response rate (ORR) was 59.1%, the complete response rate (CRR) was 50.0%. The mPFS was 6 months and the 1-year overall survival rate was 77.8%. Cytokine release syndrome (CRS) occurred in 13 patients (59.1%), with 54.5% of grade 1−2 CRS. Only one patient (4.5%) experienced grade 3 CRS and grade 3 neurotoxicity.

Here, we aimed to identify prognostic genes of GC using computational analysis. Methods We first used microarray technology to profile gene expression of GC and paired nontumor tissues from 198 patients. Based on these profiles and patients’ clinical information, we next identified prognostic genes using novel computational approaches. Phosphoglucose isomerase, also known as glucose-6-phosphate isomerase (GPI), which ranked first among 27 candidate genes, was further investigated by a new analytical tool namely enviro-geno-pheno-state (E-GPS) analysis. Suitability of GPI as a prognostic marker, and its relationship with physiological processes such as metabolism, epithelial-mesenchymal transition (EMT), as well as drug sensitivity were evaluated using both our own and independent public datasets. Results We found that higher expression of GPI in GC correlated with prolonged survival of patients. Particularly, a combination of CDH2 and GPI expression effectively stratified the outcomes of patients with TNM stage II/III. Down-regulation of GPI in tumor tissues correlated well with depressed glucose metabolism and fatty acid synthesis, as well as enhanced fatty acid oxidation and creatine metabolism, indicating that GPI represents a suitable marker for increased probability of EMT in GC cells. Conclusions Our findings strongly suggest that GPI acts as a novel biomarker candidate for GC prognosis, allowing greatly enhanced clinical management of GC patients. The potential metabolic rewiring correlated with GPI also provides new insights into studying the relationship between cancer metabolism and patient survival.","PeriodicalId":9882,"journal":{"name":"Chinese Journal of Cancer Research","volume":"31 1","pages":"771 - 784"},"PeriodicalIF":5.1,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44744918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods This study consisted of 89 consecutive patients with surgically confirmed HCC. Texture features were extracted from multiparametric MRI based on whole-lesion regions of interest. The Ki-67 status was immunohistochemical determined and classified into low Ki-67 (labeling index ≤15%) and high Ki-67 (labeling index >15%) groups. Least absolute shrinkage and selection operator (LASSO) and multivariate logistic regression were applied for generating the texture signature, clinical nomogram and combined nomogram. The discrimination power, calibration and clinical usefulness of the three models were evaluated accordingly. Recurrence-free survival (RFS) rates after curative hepatectomy were also compared between groups. Results A total of 13 texture features were selected to construct a texture signature for predicting Ki-67 status in HCC patients (C-index: 0.878, 95% confidence interval: 0.791−0.937). After incorporating texture signature to the clinical nomogram which included significant clinical variates (AFP, BCLC-stage, capsule integrity, tumor margin, enhancing capsule), the combined nomogram showed higher discrimination ability (C-index: 0.936vs. 0.795, P<0.001), good calibration (P>0.05 in Hosmer-Lemeshow test) and higher clinical usefulness by decision curve analysis. RFS rate was significantly lower in the high Ki-67 group compared with the low Ki-67 group after curative surgery (63.27%vs. 85.00%, P<0.05).

Studies have revealed that GC patients with LVI have a poorer prognosis than those without LVI. Methods In total, 1,007 patients with curatively resected GC at Department of Gastric Cancer, Tianjin Medical University Cancer Institute and Hospital were retrospectively enrolled. The patients were categorized into two groups based on the LVI status: a positive group (PG; presence of LVI) and a negative group (NG; absence of LVI). The clinicopathological factors corrected with LVI and prognostic variables were analyzed. Additionally, a pathological lymphovascular-node (lvN) classification system was proposed to evaluate the superiority of its prognostic prediction of GC patients compared with that of the eighth edition of the N staging system. Results Two hundred twenty-four patients (22.2%) had LVI. The depth of invasion and lymph node metastasis were independently associated with the presence of LVI. GC patients with LVI demonstrated a significantly lower overall survival (OS) rate than those without LVI (42.8% vs. 68.9%, respectively; P<0.001). In multivariate analysis, LVI was identified as an independent prognostic factor for GC patients (hazard ratio: 1.370; 95% confidence interval: 1.094−1.717; P=0.006).
