To provide a complete toxicity profile, toxicity spectrum, and a safety ranking of immune checkpoint inhibitor (ICI) drugs for treatment of cancer.
Systematic review and network meta-analysis.
...Electronic databases (PubMed, Embase, Cochrane Library, and Web of Science) were systematically searched to include relevant studies published in English between January 2007 and February 2018.
Only head-to-head phase II and III randomised controlled trials comparing any two or three of the following treatments or different doses of the same ICI drug were included: nivolumab, pembrolizumab, ipilimumab, tremelimumab, atezolizumab, conventional therapy (chemotherapy, targeted therapy, and their combinations), two ICI drugs, or one ICI drug with conventional therapy. Eligible studies must have reported site, organ, or system level data on treatment related adverse events. High quality, single arm trials and placebo controlled trials on ICI drugs were selected to establish a validation group.
36 head-to-head phase II and III randomised trials (n=15 370) were included. The general safety of ICI drugs ranked from high to low for all adverse events was as follows: atezolizumab (probability 76%, pooled incidence 66.4%), nivolumab (56%, 71.8%), pembrolizumab (55%, 75.1%), ipilimumab (55%, 86.8%), and tremelimumab (54%, not applicable). The general safety of ICI drugs ranked from high to low for severe or life threatening adverse events was as follows: atezolizumab (49%, 15.1%), nivolumab (46%, 14.1%), pembrolizumab (72%, 19.8%), ipilimumab (51%, 28.6%), and tremelimumab (28%, not applicable). Compared with conventional therapy, treatment-related adverse events for ICI drugs occurred mainly in the skin, endocrine, hepatic, and pulmonary systems. Taking one ICI drug was generally safer than taking two ICI drugs or one ICI drug with conventional therapy. Among the five ICI drugs, atezolizumab had the highest risk of hypothyroidism, nausea, and vomiting. The predominant treatment-related adverse events for pembrolizumab were arthralgia, pneumonitis, and hepatic toxicities. The main treatment-related adverse events for ipilimumab were skin, gastrointestinal, and renal toxicities. Nivolumab had a narrow and mild toxicity spectrum, mainly causing endocrine toxicities. Integrated evidence from the pooled incidences, subgroup, and sensitivity analyses implied that nivolumab is the best option in terms of safety, especially for the treatment of lung cancer.
Compared with other ICI drugs used to treat cancer, atezolizumab had the best safety profile in general, and nivolumab had the best safety profile in lung cancer when taking an integrated approach. The safety ranking of treatments based on ICI drugs is modulated by specific treatment-related adverse events.

Objectives To investigate prognostic-related gene signature based on DNA damage repair and tumor microenvironment statue in human papillomavirus 16 negative (HPV16-) head and neck squamous cell ...carcinoma (HNSCC). Methods For the RNA-sequence matrix in HPV16- HNSCC in the Cancer Genome Atlas (TCGA) cohort, the DNA damage response (DDR) and tumor microenvironment (TM) status of each patient sample was estimated by using the ssGSEA algorithm. Through bioinformatics analysis in DDR_high/TM_high (n = 311) and DDR_high/TM_low (n = 53) groups, a survival-related gene signature was selected in the TCGA cohort. Two independent external validation cohorts (GSE65858 (n = 210) and GSE41613 (n = 97)) with HPV16- HNSCC patients validated the gene signature. Correlations among the clinical-related hub differentially expressed genes (DEGs) and infiltrated immunocytes were explored with the TIMER2.0 server. Drug screening based on hub DEGs was performed using the CellMiner and GSCALite databases. The loss-of-function studies were used to evaluate the effect of screened survival-related gene on the motility of HPV- HNSCC cells in vitro. Results A high DDR level (P = 0.025) and low TM score (P = 0.012) were independent risk factors for HPV16- HNSCC. Downregulated expression of ALOX12B or SPRR1A was associated with poor survival rate and advanced cancer stages. The pathway enrichment analysis showed the DDR_high/TM_low samples were enriched in glycosphingolipid biosynthesis-lacto and neolacto series, glutathione metabolism, platinum drug resistance, and ferroptosis pathways, while the DDR_high/TM_low samples were enriched in Th17 cell differentiation, Neutrophil extracellular trap formation, PD - L1 expression and PD - 1 checkpoint pathway in cancer. Notably, the expression of ALOX12B and SPRR1A were negatively correlated with cancer-associated fibroblasts (CAFs) infiltration and CAFs downstream effectors. Sensitivity to specific chemotherapy regimens can be derived from gene expressions. In addition, ALOX12B and SPRR1A expression was associated with the mRNA expression of insulin like growth factor 1 receptor (IGF1R), AKT serine/threonine kinase 1 (AKT1), mammalian target of rapamycin (MTOR), and eukaryotic translation initiation factor 4E binding protein 1 (EIF4EBP1) in HPV negative HNSCC. Down-regulation of ALOX12B promoted HPV- HNSCC cells migration and invasion in vitro. Conclusions ALOX12B and SPRR1A served as a gene signature for overall survival in HPV16- HNSCC patients, and correlated with the amount of infiltrated CAFs. The specific drug pattern was determined by the gene signature.

Gene expression patterns can be used as prognostic biomarkers in various types of cancers. We aimed to identify a gene expression pattern for individual distant metastatic risk assessment in patients ...with locoregionally advanced nasopharyngeal carcinoma.
In this multicentre, retrospective, cohort analysis, we included 937 patients with locoregionally advanced nasopharyngeal carcinoma from three Chinese hospitals: the Sun Yat-sen University Cancer Center (Guangzhou, China), the Affiliated Hospital of Guilin Medical University (Guilin, China), and the First People's Hospital of Foshan (Foshan, China). Using microarray analysis, we profiled mRNA gene expression between 24 paired locoregionally advanced nasopharyngeal carcinoma tumours from patients at Sun Yat-sen University Cancer Center with or without distant metastasis after radical treatment. Differentially expressed genes were examined using digital expression profiling in a training cohort (Guangzhou training cohort; n=410) to build a gene classifier using a penalised regression model. We validated the prognostic accuracy of this gene classifier in an internal validation cohort (Guangzhou internal validation cohort, n=204) and two external independent cohorts (Guilin cohort, n=165; Foshan cohort, n=158). The primary endpoint was distant metastasis-free survival. Secondary endpoints were disease-free survival and overall survival.
We identified 137 differentially expressed genes between metastatic and non-metastatic locoregionally advanced nasopharyngeal carcinoma tissues. A distant metastasis gene signature for locoregionally advanced nasopharyngeal carcinoma (DMGN) that consisted of 13 genes was generated to classify patients into high-risk and low-risk groups in the training cohort. Patients with high-risk scores in the training cohort had shorter distant metastasis-free survival (hazard ratio HR 4·93, 95% CI 2·99–8·16; p<0·0001), disease-free survival (HR 3·51, 2·43–5·07; p<0·0001), and overall survival (HR 3·22, 2·18–4·76; p<0·0001) than patients with low-risk scores. The prognostic accuracy of DMGN was validated in the internal and external cohorts. Furthermore, among patients with low-risk scores in the combined training and internal cohorts, concurrent chemotherapy improved distant metastasis-free survival compared with those patients who did not receive concurrent chemotherapy (HR 0·40, 95% CI 0·19–0·83; p=0·011), whereas patients with high-risk scores did not benefit from concurrent chemotherapy (HR 1·03, 0·71–1·50; p=0·876). This was also validated in the two external cohorts combined. We developed a nomogram based on the DMGN and other variables that predicted an individual's risk of distant metastasis, which was strengthened by adding Epstein–Barr virus DNA status.
The DMGN is a reliable prognostic tool for distant metastasis in patients with locoregionally advanced nasopharyngeal carcinoma and might be able to predict which patients benefit from concurrent chemotherapy. It has the potential to guide treatment decisions for patients at different risk of distant metastasis.

Background
The prognosis of patients who have Epstein‐Barr virus (EBV)‐related nasopharyngeal carcinoma (NPC) in which the tumor tissues harbor EBV have a better prognosis than those without ...EBV‐related NPC. Therefore, the eighth edition of the TNM staging system could be modified for EBV‐related NPC by incorporating the measurement of plasma EBV DNA.
Methods
In total, 979 patients with NPC who received intensity‐modulated radiotherapy (IMRT) were retrospectively reviewed. Recursive partitioning analysis was conducted based on tumor (T) classification, lymph node (N) classification, and EBV DNA measurement to derive objectively the proposed stage groupings. The validity of the proposed stage groupings was confirmed in a prospective cohort of 550 consecutive patients who also received with IMRT.
Results
The pretreatment plasma EBV DNA level was identified as a significant, negative prognostic factor for progression‐free survival and overall survival in univariate analysis (all P < .001) and multivariate analysis (all P < .05). Recursive partitioning analysis of the primary cohort to incorporate EBV DNA generated the following proposed stage groupings: stage RI (T1N0), RIIA (T2‐T3N0 or T1‐T3N1, EBV DNA ≤2000 copies/mL), stage RIIB (T2‐T3N0 or T1‐T3N1, EBV DNA >2000 copies/mL; T1‐T3N2, EBV DNA ≤2000 copies/mL), stage RIII (T1‐T3N2, EBV DNA >2000 copies/mL; T4N0‐N2), and stage RIVA (any T and N3). In the validation cohort, the 5‐year progression‐free survival rate was 100%, 87.9%, 76.7%, 68.7%, and 50.4% for proposed stage RI, RIIA, RIIB, RIII, and RIV NPC, respectively (P < .001). Compared with the eighth edition TNM stage groupings, the proposed stage groupings incorporating EBV DNA provided better hazard consistency, hazard discrimination, outcome prediction, and sample size balance.
Conclusions
The proposed stage groupings have better prognostic performance than the eighth edition of the TNM staging system. EBV DNA titers should be included in the TNM staging system to assess patients who have EBV‐related NPC.
The proposed stage groupings incorporating Epstein‐Barr virus DNA by Recursive partitioning analysis have better prognostic performance than the eighth edition American Joint Committee on Cancer/Union for International Cancer Control TNM staging system. Compared with the eighth edition, the proposed stage groupings incorporating Epstein‐Barr virus DNA provide better hazard consistency, hazard discrimination, outcome prediction, and sample size balance

Background: The prognostic values of staging parameters require continual re-assessment amid changes in diag-nostic and therapeutic methods. This study aimed to identify the prognostic factors and ...failure patterns of non-meta-static nasopharyngeal carcinoma(NPC) in the intensity-modulated radiotherapy(IMRT) era.Methods: We reviewed the data from 749 patients with newly diagnosed, biopsy-proven, non-metastatic NPC in our cancer center(South China, an NPC endemic area) between January 2003 and December 2007. All patients under-went magnetic resonance imaging(MRI) before receiving IMRT. The actuarial survival rates were estimated using the Kaplan–Meier method, and survival curves were compared using the log-rank test. Multivariate analyses with the Cox proportional hazards model were used to test for the independent prognostic factors by backward eliminating insigniicant explanatory variables.Results: The 5-year occurrence rates of local failure, regional failure, locoregional failure, and distant failure were 5.4, 3.0, 7.4, and 17.4%, respectively. The 5-year survival rates were as follows: local relapse-free survival, 94.6%; nodal relapse-free survival, 97.0%; distant metastasis-free survival, 82.6%; disease-free survival, 75.1%; and overall survival, 82.0%. Multivariate Cox regression analysis revealed that orbit involvement was the only signiicant prognostic fac-tor for local failure(P = 0.011). Parapharyngeal tumor extension, retropharyngeal lymph node involvement, and the laterality, longest diameter, and Ho's location of the cervical lymph nodes were signiicant prognostic factors for both distant failure and disease failure(all P 〈 0.05). Intracranial extension had signiicant prognostic value for distant failure(P = 0.040).Conclusions: The key failure pattern for NPC was distant metastasis in the IMRT era. With changes in diagnostic and therapeutic technologies as well as treatment modalities, the signiicant prognostic parameters for local control have also been altered substantially.
To report long‐term results of a randomized controlled trial that compared cisplatin/fluorouracil/docetaxel (TPF) induction chemotherapy (IC) plus concurrent chemoradiotherapy (CCRT) with CCRT alone ...in locoregionally advanced nasopharyngeal carcinoma (NPC). Patients with stage III–IVB (except T3–4 N0) NPC were randomly assigned to receive IC plus CCRT (n = 241) or CCRT alone (n = 239). IC included three cycles of docetaxel (60 mg/m2 d1), cisplatin (60 mg/m2 d1), and fluorouracil (600 mg/m2/d civ d1–5) every 3 weeks. Patients from both groups received intensity‐modulated radiotherapy concurrently with three cycles of 100 mg/m2 cisplatin every 3 weeks. After a median follow‐up of 71.5 months, the IC plus CCRT group showed significantly better 5‐year failure‐free survival (FFS, 77.4% vs. 66.4%, p = 0.019), overall survival (OS, 85.6% vs. 77.7%, p = 0.042), distant failure‐free survival (88% vs. 79.8%, p = 0.030), and locoregional failure‐free survival (90.7% vs. 83.8%, p = 0.044) compared to the CCRT alone group. Post hoc subgroup analyses revealed that beneficial effects on FFS were primarily observed in patients with N1, stage IVA, pretreatment lactate dehydrogenase ≥170 U/l, or pretreatment plasma Epstein–Barr virus DNA ≥6000 copies/mL. Two nomograms were further developed to predict the potential FFS and OS benefit of TPF IC. The incidence of grade 3 or 4 late toxicities was 8.8% (21/239) in the IC plus CCRT group and 9.2% (22/238) in the CCRT alone group. Long‐term follow‐up confirmed that TPF IC plus CCRT significantly improved survival in locoregionally advanced NPC with no marked increase in late toxicities and could be an option of treatment for these patients.
What's new?
Despite advances in the treatment of nasopharyngeal carcinoma, approximately 30% of high‐risk patients experience recurrence after treatment. Here the authors find that combining the conventional chemoradiotherapy with a triple induction chemotherapy (cisplatin/fluorouracil/docetaxel) prolonged survival of patients with locoregionally advanced cancer, even after more than 70 months of follow‐up. The combination treatment increased acute, but not late, toxicities, and the authors propose that it could present a new treatment option for this patient group.

Adding three cycles of induction chemotherapy with gemcitabine and cisplatin to concurrent chemoradiotherapy improved 3-year recurrence-free survival (85.3%, vs. 76.5% with concurrent ...chemoradiotherapy alone) and overall survival (94.6% vs. 90.3%). Patients receiving induction chemotherapy were more likely to have grade 3 or 4 myelosuppression, nausea, and vomiting.
We aimed to evaluate the value of deep learning on positron emission tomography with computed tomography (PET/CT)-based radiomics for individual induction chemotherapy (IC) in advanced nasopharyngeal ...carcinoma (NPC).
We constructed radiomics signatures and nomogram for predicting disease-free survival (DFS) based on the extracted features from PET and CT images in a training set (
= 470), and then validated it on a test set (
= 237). Harrell's concordance indices (C-index) and time-independent receiver operating characteristic (ROC) analysis were applied to evaluate the discriminatory ability of radiomics nomogram, and compare radiomics signatures with plasma Epstein-Barr virus (EBV) DNA.
A total of 18 features were selected to construct CT-based and PET-based signatures, which were significantly associated with DFS (
< 0.001). Using these signatures, we proposed a radiomics nomogram with a C-index of 0.754 95% confidence interval (95% CI), 0.709-0.800 in the training set and 0.722 (95% CI, 0.652-0.792) in the test set. Consequently, 206 (29.1%) patients were stratified as high-risk group and the other 501 (70.9%) as low-risk group by the radiomics nomogram, and the corresponding 5-year DFS rates were 50.1% and 87.6%, respectively (
< 0.0001). High-risk patients could benefit from IC while the low-risk could not. Moreover, radiomics nomogram performed significantly better than the EBV DNA-based model (C-index: 0.754 vs. 0.675 in the training set and 0.722 vs. 0.671 in the test set) in risk stratification and guiding IC.
Deep learning PET/CT-based radiomics could serve as a reliable and powerful tool for prognosis prediction and may act as a potential indicator for individual IC in advanced NPC.
Detectable post‐therapy plasma Epstein–Barr virus (EBV) DNA predicts poor survival in non‐metastatic nasopharyngeal carcinoma (NPC). However, some patients subsequently experience spontaneous ...remission of residual EBV DNA during follow‐up and it was unclear whether these patients were still at high risk of disease failure. Using the NPC database from an established big‐data intelligence platform, 3269 NPC patients who had the plasma EBV DNA load measured at the end of therapy (± 1 week) were identified. In total, 93.0% (3031/3269) and 7.0% (238/3269) of patients had undetectable and detectable (> 0 copy/ml) plasma EBV DNA at the end of therapy (EBV DNAend), respectively. Detectable EBV DNAend was a prognostic factor for poorer 3‐year disease‐free survival (DFS), overall survival (OS), distant metastasis‐free survival (DMFS), and loco‐regional recurrence‐free survival (LRRFS) in both univariate and multivariate analyses. Of 238 patients with residual EBV DNAend, 192 underwent EBV DNA assay 3 months after and spontaneous remission occurred in 72.4% (139/192). However, these patients still had poorer 3‐year DFS (55.1% vs. 89.8%), OS (79.1% vs. 96.2%), DMFS (68.4% vs. 94.1%) and LRRFS (84.5% vs. 95.0%) than patients with undetectable EBV DNAend (all p < 0.001). And patients with persistent detectable post‐therapy EBV DNA had the worst outcomes. These results were confirmed in multivariate analysis. In conclusion, residual EBV DNA post therapy was a robust biomarker for NPC prognosis. Although residual post‐therapy EBV DNA could spontaneous remit during follow‐up, these patients were still at high risk of disease failure and such patients may benefit from adjuvant therapy.
What's new?
Maintenance of circulating Epstein‐Barr virus (EBV) DNA after treatment is associated with poor disease outcome in patients with nasopharyngeal carcinoma. Here the authors focused on the small percentage of patients who initially maintain EBV DNA after therapy but eventually clear this marker from their blood. These patients maintain a high risk of disease failure when compared to patients with no detectable post‐therapy EBV DNA, underscoring the prognostic value of nuanced EBV DNA measurements after nasopharyngeal cancer treatment.
