Immunotherapy has revolutionized cancer treatment and substantially improved patient outcomes with respect to multiple types of tumors. 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.

Objective Anti-vascular endothelial growth factor (VEGF) monoclonal antibodies are an effective means of treating non-small cell lung cancer (NSCLC). 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%). Conclusions This study reported that QL1101 had similar efficacy in treating nonsquamous NSCLC in terms of ORR, PFS and OS based on two-year updated data, providing a basis for the clinical application of QL1101.
目的抗血管内皮生长因子(VEGF)单克隆抗体是治疗非小细胞肺癌(NSCLC)的有效手段。在这里，我们的目标是基于两年随访数据更新QL1101和贝伐单抗之间的等效疗效评估。方法本随机对照试验共纳入535例符合条件的非小细胞肺癌患者。患者按1:1的比例随机分配到QL1101组和贝伐单抗组。本研究的完整结束时间定义为最后一名入组患者随机化后的24个月。主要终点为客观缓解率(ORR);如果相对风险的双侧90%置信区间(90% CI)在0.75 - 1.33范围内，则确认等效性。次要终点是无进展生存期(PFS)和总生存期(OS)。结果两年更新的数据显示相似的ORR (QL1101 vs.贝伐单抗:53.1% vs. 54.3%;相对危险度= 0.977;QL1101组和贝伐单抗组之间的90% CI: 0.838−1.144)、PFS (235 d vs. 254 d, log-rank P=0.311)和OS (577 d vs. 641 d, log-rank P=0.099)结果。QL1101组和贝伐单抗组的目标病灶平均收缩率也相似(22.5% vs 23.5%)。对于接受QL1101维持治疗的患者，QL1101组(n=157)和贝伐单抗组(n=148)的结果相似(PFS: 253 d vs 272 d, log-rank P=0.387;OS: 673 d vs. 790 d, log-rank P=0.101;平均肿瘤收缩率:26.6% vs. 27.5%)。结论本研究基于2年更新数据，报告了QL1101治疗非鳞状NSCLC在ORR、PFS和OS方面具有相似的疗效，为QL1101的临床应用提供了依据。

Objective Previous studies reported that 4-1BB-based CD19 chimeric antigen receptor (CAR)-T cells were more beneficial for the clinical outcomes than CD28-based CAR-T cells, especially the lower incidence rate of severe adverse events. 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. Conclusions These results demonstrated the safety and durable efficacy of a 4-1BB-based CD19 CAR-T, IM19, which is promising for further development and clinical investigation.

In addition to the important role of contextuality in foundations of quantum theory, this intrinsically quantum property has been identified as a potential resource for quantum advantage in different tasks. It is thus of fundamental importance to study contextuality from the point of view of resource theories, which provide a powerful framework for the formal treatment of a property as an operational resource. In this contribution, we review recent developments towards a resource theory of contextuality and connections with operational applications of this property. This article is part of the theme issue 'Contextuality and probability in quantum mechanics and beyond'.

Objective Tumor heterogeneity renders identification of suitable biomarkers of gastric cancer (GC) challenging. 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.

Objective To investigate the value of whole-lesion texture analysis on preoperative gadoxetic acid enhanced magnetic resonance imaging (MRI) for predicting tumor Ki-67 status after curative resection in patients with hepatocellular carcinoma (HCC). 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). Conclusions Texture analysis on gadoxetic acid enhanced MRI can serve as a noninvasive approach to preoperatively predict Ki-67 status of HCC after curative resection. The combination of texture signature and clinical factors demonstrated the potential to further improve the prediction performance.

Objective: Colorectal cancer (CRC) causes a substantial burden of disease in China and the evidence of economic burden triggered is fundamental for priority setting. The aim of this survey was to quantify medical expenditures and the time trends for CRC diagnosis and treatment in China.
Methods: From 2012 to 2014, a hospital-based multicenter retrospective survey was conducted in 13 provinces across China. For each eligible CRC patient diagnosed from 2002 to 2011, clinical information and expenditure data were extracted using a uniform questionnaire. All expenditure data were reported in Chinese Yuan (CNY) using 2011 values.
Results: Of the 14,536 CRC patients included, the average age at diagnosis was 58.2 years and 15.8% were stage-I cases. The average medical expenditure per patient was estimated at 37,902 CNY [95 % confidence interval (95% CI): 37,282-38,522], and the annual average increase rate was 9.2% from 2002 to 2011 (P for trend <0.001), with a cumulative increase of 2.4 times (from 23,275 CNY to 56,010 CNY). The expenditure per patient in stages I, II, III and IV were 31,698 CNY, 37,067 CNY, 38,918 CNY and 42,614 CNY, respectively (P<0.001). Expenditure significantly differed within various subgroups. Expenses for drugs contributed the largest proportion (52.6%).
Conclusions: These conservative estimates illustrated that medical expenditures for CRC diagnosis and treatment in tertiary hospitals in China were substantial and increased rapidly over the 10 years, with drugs continually being the main expense by 2011. Relatively, medical expenditures are lower for CRC in the earlier stages. These findings will facilitate the economic evaluation of CRC prevention and control in China.

Objective To evaluate the efficacy and safety profile of first-line bevacizumab (Bev)-containing pemetrexed-platinum chemotherapy in a real-world Chinese cohort with advanced non-squamous non-small cell lung cancer (NS-NSCLC). Methods A total of 415 eligible patients with NS-NSCLC who received first-line pemetrexed-platinum chemotherapy at National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between February 2010 and September 2017 were reviewed retrospectively: 309 Bev(−) and 106 Bev(+) cases. Bev was administered at 7.5 mg/kg every 3 weeks in the Bev(+) group. To reduce the risk of a selection bias, a propensity score-matching (PSM) was conducted and 105 pairs of Bev(−) and Bev(+) cases were identified. Results The median duration of follow-up was 15.8 months. The median progression-free survival (PFS) was prolonged significantly in the Bev(+) group than in the Bev(−) group in overall (9.8vs. 7.8 months, P=0.006) and PSM pairs (9.8 vs. 6.6 months, P<0.001). Moreover, patients receiving maintenance therapy with pemetrexed plus Bev had longer PFS than those interrupted after induction chemotherapy, or those receiving mono-maintenance with pemetrexed (12.3vs. 4.8 vs. 8.6 months; P<0.001). Multivariate analyses revealed Bev to be one of the favorable prognostic factors for PFS, along with the predictor of maintenance therapy. Conclusions First-line induction and maintenance therapy with Bev (7.5 mg/kg every 3 weeks) combined with pemetrexed-platinum chemotherapy was efficacious and superior to non-Bev chemotherapy in Chinese patients with advanced NS-NSCLC.

Objective Lymphovascular infiltration (LVI) is frequently detected in gastric cancer (GC) specimens. 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). Using strata analysis, significant prognostic differences between the groups were only observed in patients at stage I−IIIa or N0−2. The lvN classification was found to be more appropriate to predict the OS of GC patients after curative surgery than the pN staging system. The −2 log-likelihood of lvN classification (4,746.922) was smaller than the value of pN (4,765.196), and the difference was statistically significant (χ2=18.434, P<0.001). Conclusions The presence of LVI influences the OS of GC patients at stage I−IIIa or N0−2. LVI should be incorporated into the pN staging system to enhance the accuracy of the prognostic prediction of GC patients.
