RESUMEN
BACKGROUND AND AIMS: The prognosis of hepatocellular carcinoma (HCC) with macrovascular invasion(MaVI)is poor, and the treatment is limited. This study aims to explore the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC), combined with lenvatinib and programmed cell death-1(PD-1) inhibitor in the first-line treatment of HCC with MaVI. METHODS: From July 2020 to February 2022, we retrospectively analyzed consecutive patients with HCC with MaVI who received hepatic arterial infusion FOLFOX(oxaliplatin, 5-fluorouracil, and leucovorin)combined with lenvatinib and PD-1 inhibitor. The efficacy was evaluated by RECIST 1.1. Kaplan-Meier was used to explore the overall survival and progression-free survival (PFS), and the COX regression model was used to analyze the risk factors of PFS. Adverse events (AEs) were evaluated according to CTCAE5.0. RESULTS: Thirty-two patients with HCC complicated with MaVI were recruited from the Second Affiliated Hospital of Nanchang University. Among the patients treated with HAIC combined with lenvatinib and PD-1 inhibitor, ten patients (31.25%) got partial response, eighteen patients (56.25%) maintained stable disease and four patients (12.50%) suffered progressive disease during follow-up; and objective response rate was 31.25%, and disease control rate was 87.5%. The median PFS was 179 days. Univariate and multivariate Cox analysis showed that the extrahepatic metastases and Child-Pugh score were independent prognostic factors of PFS. Twenty-two (68.75%) patients suffered adverse reactions. The main AEs were elevated transaminase (46.87%), thrombocytopenia (40.63%), hypoalbuminemia (28.13%), nausea and vomiting (21.88%), leukopenia (18.76%), abdominal pain (15.63%), hypertension (15.63%) and fever (15.63%). There were seven cases (21.88%) that had grade 3 or above AEs; Among them, two cases with elevated transaminase (6.25%), leukopenia, thrombocytopenia, nausea and vomiting, abdominal pain, and diarrhea occurred in one case respectively. Moreover, no treatment-related death was observed. CONCLUSIONS: Hepatic arterial infusion of FOLFOX combined with lenvatinib and PD-1 inhibitor as the first-line treatment for HCC complicated with MaVI is effective, and adverse reactions are tolerable.

PURPOSE: The prevention of recurrence for patients with hepatocellular carcinoma after curative resection is still a great challenge in clinical practice. There are numerous studies that trying to search for favorable strategies to decrease the recurrence and prolong life span for these patients, whereas no consensus is reached till now. Herein, we aim to compare the efficacy between different reported treatments by network meta-analysis(NMA). METHODS: We searched Pubmed, Web of Science and Cochrane Library for abstracts and full-text articles published from database inception through February 2023. All of the random controlled trials(RCTs) were evaluated and collected as eligible studies. The primary outcome was the prevention of recurrence between different procedures. The second outcomes were one-year survival, three-year survival and five-year survival. RESULTS: Thirty-two RCTs including 5783 patients were selected, and 12 treatments were classified. Most of the studies were high quality with low bias. Thirty-one studies including 5629 patients were recruited for recurrence analysis. The network meta-analysis showed benefits from transarterial chemoembolization(TACE) + portal vein chemotherapy(PVC)[OR, 2.84 (1.15,6.99)] and internal radiotherapy(IRT) [OR, 2.63 (1.41,4.91)] compared to non-adjuvant(NA) treatment when considering prevention of recurrence. Seventeen studies including 2047 patients were collected for one-year survival analysis. The network meta-analysis showed benefit from TACE[OR, 0.33 (0.14,0.75)] when considering one-year survival. Twenty-one studies including 2463 patients were collected for three-year survival analysis. The network meta-analysis showed TACE [OR, 0.51 (0.30,0.86)], IRT[OR, 0.41 (0.20,0.83)] and dendritic cell(DC) [OR, 0.09 (0.01,0.98)] were better than NA when considering three-year survival. Sixteen studies including 1915 patients were collected for five-year survival analysis. The network meta-analysis didn't show any benefit from different treatments when considering five-year survival. Other strategies including external radiotherapy(ERT), branched-chain amino acids(BCAA), hepatic artery infusion chemotherapy(HAIC), cytokine-induced killer(CIK), adoptive immunotherapy(AIT), Huaier, interferon(IFN), oral chemotherapy(OCT) and sorafenib(SOR) didn't show significant benefit regardless of prevention of recurrence or short-, long- time survival. CONCLUSION: This NMA found that TACE + PVC and IRT were considered as the procedures to decrease HCC recurrence rate. TACE, IRT and DC were preferred when considering the extending of life span for post-operative patients with HCC. Large scale of RCTs are needed to verify it.

Hepatocellular carcinoma (HCC) is a lethal disease with limited management strategies and poor prognosis. Metabolism alternations have been frequently unveiled in HCC, including glutamine metabolic reprogramming. The components of glutamine metabolism, such as glutamine synthetase, glutamate dehydrogenase, glutaminase, metabolites, and metabolite transporters, are validated to be potential biomarkers of HCC. Increased glutamine consumption is confirmed in HCC, which fuels proliferation by elevated glutamate dehydrogenase or upstream signals. Glutamine metabolism also serves as a nitrogen source for amino acid or nucleotide anabolism. In addition, more glutamine converts to glutathione as an antioxidant in HCC to protect HCC cells from oxidative stress. Moreover, glutamine metabolic reprogramming activates the mTORC signaling pathway to support tumor cell proliferation. Glutamine metabolism targeting therapy includes glutamine deprivation, related enzyme inhibitors, and transporters inhibitors. Together, glutamine metabolic reprogramming plays a pivotal role in HCC identification, proliferation, and progression.
RESUMEN
Background: The drug-eluting beads transarterial chemoembolization (DEB-TACE) has already been used in hepatic malignancies. We aim to evaluate the efficacy and safety of DEB-TACE in treating primary or secondary liver cancer. Methods: We retrospectively evaluated 59 patients with hepatic malignancies, including 41 patients with primary liver cancer and 18 patients with secondary liver cancer, between September 2016 and February 2019. All patients were treated with DEB-TACE. Objective response rate (ORR) and disease control rate (DCR) were evaluated by mRECIST. The pain was assessed using a numerical rating scale (NRS) where 0 represented no pain, and a score of ten was unbearable. Adverse reactions were assessed according to Common Terminology Criteria for Adverse Events 4.0 (CTCAE4.0). Results: In the subgroup of primary liver cancer, 3 patients (7.32%) got complete response, 13 patients (31.71%) got partial response, 21 patients (51.22%) experienced stable disease, and 4 patients (9.76%) suffered progressive disease; ORR was 39.02% and DCR was 90.24%. In the subgroup of secondary liver cancer, 0 patients (0%) got complete response, 6 patients (33.33%) got partial response, 11 patients (61.11%) experienced stable disease, and 1 patient (5.56%) suffered progressive disease; ORR was 33.33% and DCR was 94.44%. We did not find any difference when comparing the efficacy between primary and secondary liver cancer (P=0.612). The one-year survival rate was 70.73% for primary liver cancer and 61.11% for secondary liver cancer. There was no significant difference between the two groups (P=0.52). For the patients with CR or PR, no factor could predict the efficacy of DEB-TACE. The most common treatment-related adverse reactions were short-term liver function disorders. The symptoms included fever (20.34%), abdomen pain (16.95%), and vomiting (5.08%), all patients with adverse reactions got remission after treatment. Conclusions: DEB-TACE has a promising effect in the treatment of primary or secondary liver cancer. The treatment-related adverse reactions are tolerable.

BACKGROUND: Chemotherapy is the standard treatment for triple-negative breast cancer (TNBC). Whether the addition of PARP inhibitors improves treatment efficacy remains controversial clinically. Thus, we performed a meta-analysis to compare the efficacy and safety of combination treatment (PC) and chemotherapy alone (CA). METHODS: Relevant studies were identified through searches of 7 databases. The primary endpoints were progression-free survival (PFS) and overall survival (OS). RESULTS: We screened 317 studies and included seven RCTs involving 2091 patients in the final analysis. PC tended to have better efficacy than CA according to PFS (HR [hazard ratio]: 0.83 [0.75, 0.93], p = 0.001), OS (HR: 0.89 [0.76,1.03], p = 0.11) and overall response rate (ORR) (RR [risk ratio]: 1.19 [0.97,1.46], p = 0.10). However, grade 3-5 AEs (RR: 1.50 [0.87,2.61], p = 0.15) were observed in the PC group. In the PC arm, the 10 most-reported grade 3-5 AEs were neutropenia (62.8%), anemia (28.5%), thrombocytopenia (26.4%), lymphopenia (19.05%), leukopenia (16.9%), fatigue (5%), heart failure (4.76%), lung infection (4.76%), thromboembolic events (4.76%) and ventricular tachycardia (4.76%). Similar results for pathological complete response (pCR), total AEs, rate of complete response (CR), stable disease (SD) and progressive disease (PD), breast conservation rate (BCR), and drug discontinuation (DD) rate were found between the two groups. CONCLUSIONS: For TNBC treatment, the combination of PARP inhibitors and chemotherapy appears to be superior to chemotherapy alone with better antitumor efficacy. However, its higher rate of AEs needs to be taken seriously. More high-quality RCTs are needed to confirm these results.

BACKGROUND: Several treatments induce liver hypertrophy for patients with liver malignancies but insufficient future liver remnant (FLR). Herein, the aim of this study is to compare the efficacy and safety of existing surgical techniques using network meta-analysis (NMA). METHODS: We searched PubMed, Web of Science, and Cochrane Library from databases for abstracts and full-text articles published from database inception through Feb 2022. The primary outcome was the efficacy of different procedures, including standardized FLR (sFLR) increase, time to hepatectomy, resection rate, and R0 resection margin. The secondary outcome was the safety of different treatments, including the rate of Clavien-Dindo≥3a and 90-day mortality. RESULTS: Twenty-seven studies, including three randomized controlled trials (RCTs), three prospective trials (PTs), and twenty-one retrospective trials (RTs), and a total number of 2075 patients were recruited in this study. NMA demonstrated that the Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) had much higher sFLR increase when compared to portal vein embolization (PVE) (55.25%, 95% CI 45.27-65.24%), or liver venous deprivation(LVD) (43.26%, 95% CI 22.05-64.47%), or two-stage hepatectomy (TSH) (30.53%, 95% CI 16.84-44.21%), or portal vein ligation (PVL) (58.42%, 95% CI 37.62-79.23%). ALPPS showed significantly shorter time to hepatectomy when compared to PVE (-32.79d, 95% CI -42.92-22.66), or LVD (-34.02d, 95% CI -47.85-20.20), or TSH (-22.85d, 95% CI -30.97-14.72), or PVL (-43.37d, 95% CI -64.11-22.62); ALPPS was considered as the highest resection rate when compared to TSH (OR=6.09; 95% CI 2.76-13.41), or PVL (OR =3.52; 95% CI 1.16-10.72), or PVE (OR =4.12; 95% CI 2.19-7.77). ALPPS had comparable resection rate with LVD (OR =2.20; 95% CI 0.83-5.86). There was no significant difference between them when considering the R0 marge rate. ALPPS had a higher Clavien-Dindo≥3a complication rate and 90-day mortality compared to other treatments, although there were no significant differences between different procedures. CONCLUSIONS: ALPPS demonstrated a higher regeneration rate, shorter time to hepatectomy, and higher resection rate than PVL, PVE, or TSH. There was no significant difference between them when considering the R0 marge rate. However, ALPPS developed the trend of higher Clavien-Dindo≥3a complication rate and 90-day mortality compared to other treatments.

Methods: We searched PubMed, Web of Science, and Cochrane Library for abstracts and full-text articles published from database inception through May 2022. All the random controlled trials (RCTs) were assessed and collected as eligible studies. The primary outcome was overall survival (OS). The second outcome was progression-free survival (PFS). Results: Seventeen studies, including 3632 patients, were selected from 1361 records. In the network meta-analysis for OS, gemcitabine + cisplatin (GemCis) + cediranib (HR, 0.11; 95% CI, 0.00-2.88), GemCis+durvalumab (HR, 0.27; 95% CI, 0.06-1.29), and GemCis + merestinib (HR, 0.37; 95% CI, 0.03-4.36) showed the trend of OS benefit over standard treatment (GemCis), although there was no significant difference. GemCis, GemOxa, and gemcitabine+S1 (GemS1) did not differ when comparing OS. In the network meta-analysis for PFS, GemCis+merestinib (HR, 0.67; 95% CI, 0.54-0.83) and GemCis+durvalumab (HR, 0.22; 95% CI, 0.08-0.62) showed PFS benefit over standard treatment (GemCis) with a significant difference. GemCis, GemOxa, and GemS1 did not differ when comparing PFS. Conclusion: GemCis+durvalumab might be the most promising regimen for advanced BTC when considering OS and PFS. GemOxa and GemS1 could be alternative options for advanced BTC patients with nontolerance to GemCis.

WHAT IS KNOWN AND OBJECTIVE: Whether maintenance therapy with bevacizumab (Bev) + pemetrexed (Pem) can achieve greater clinical benefits than Bev or Pem alone for stage IIIB/IV nonsquamous non-small cell lung cancer (NSCLC) remains unclear. We assessed the antitumour effect and toxicity of maintenance Bev+Pem versus maintenance with single-agent Bev/Pem in this meta-analysis. METHODS: Appropriate randomized controlled trials (RCTs) were screened using electronic databases (Google Scholar, PubMed, Embase, Scopus, ScienceDirect, Ovid MEDLINE, Cochrane and Web of Science). The endpoints were progression-free survival (PFS), overall survival (OS) and adverse events (AEs). RESULTS AND DISCUSSION: We included six RCTs that contained 2,447 patients receiving induction therapy with platinum-based combination therapies. The maintenance therapy Bev+Pem group had prolonged PFS (HR = 0.74, 95% CI 0.69-0.80, p < 0.00001) and OS (HR = 0.91, 95% CI 0.83-0.99, p = 0.02) compared with the Bev/Pem group. Moreover, we further analysed the PFS rate (PFSR) and OS rate (OSR) and found that the Bev+Pem group exhibited improved PFSR-0.5y, PFSR-1y, PFSR-1.5y, PFSR-2y and OS-2y, with preferable trends in OS-1y, OS-3y and OS-4y compared with the Bev/Pem single-agent maintenance therapy. In addition, subgroup analyses indicated that the Bev+Pem group had greater PFS and OS among patients aged <65 years, patients with an Eastern Cooperative Oncology Group (ECOG) score of 0, and patients who never smoked. Regarding adverse events (AEs), the Bev+Pem group exhibited an increased occurrence of anaemia, fatigue, thrombocytopenia and anorexia. WHAT IS NEW AND CONCLUSION: For stage IIIB/IV nonsquamous NSCLC patients, maintenance therapy with Bev+Pem offers an increased survival outcome (PFS, OS) compared with monotherapy. However, the increased incidence of AEs should not be neglected.

BACKGROUND: The most effective treatment of immune checkpoint inhibitors (ICIs) is restricted in microsatellite instability (MSI-H) subsets of advanced colorectal cancer, but MSI-H only accounts for 4-5% among them. ICIs are completely ineffective in advanced colorectal cancer patients with microsatellite stable (MSS), according to literatures published. Regorafenib is a novel tyrosine kinase inhibitor (TKIs) that could normalize tumor blood vessels by inhibiting vascular endothelial growth factor receptor and its downstream, thus improving cytotoxic T cell infiltration in tumor microenvironment, which has a synergistic effect with ICIs. Toripalimab is a type of anti-PD-1 monoclonal antibody produced by Junshi Biosciences in China. Herein, we aimed to explore the efficacy and safety of regorafenib combined with toripalimab in the third-line and beyond treatment of advanced colorectal cancer. METHODS: We evaluated the outcomes of MSS patients with advanced colorectal cancer who received regorafenib combined with toripalimab in the Second Affiliated Hospital of Nanchang University from June 2019 to January 2021. These patients had previously received at least second-line treatment; the regimens were oxaliplatin and irinotecan-based chemotherapy and/or accompanied with bevacizumab or cetuximab. Thirty-three patients were treated orally with regorafenib 80 mg or 120 mg once daily for 21 days, 28 days as a cycle, combined with intravenous toripalimab until disease progression or intolerant to adverse reactions. We used the Kaplan-Meier method to estimate the rate of progression-free survival (PFS) and log-rank method to do a statistical test of the survival curve. The Cox regression model was used to analyze the influence of multiple factors on PFS. The primary endpoints were objective remission rate (ORR) and disease control rate (DCR). The secondary endpoints were the incidence of adverse reactions and median progression-free survival (mPFS). RESULTS: The evaluation of treatment effects was assessed according to RECIST 1.1. Four patients (12.12%) got partial response, twelve patients (36.36%) experienced stable disease, and seventeen patients (51.52%) suffered progressive disease. ORR was 12.12% and DCR was 48.48%. mPFS was 113 days (95% CI: 0-272.1). In univariate analysis, patients who had previously received second-line treatment were significantly better than those who had received third-line or more treatment (p=0.005). Lung metastasis was a negative factor in combined therapy (p=0.032). Five patients without previous treatment of bevacizumab were effective. Previous treatment without bevacizumab showed a trend of effective when combination therapy (p=0.034). It was also a positive factor that the Eastern Cooperative Oncology Group performance status (ECOG) score was 0 (p=0.034). Multivariable Cox regression analysis showed the number of previous chemotherapy lines and excision of primary lesions were independent prognostic factors. The most common treatment-related adverse reactions were hand-foot syndrome (33.33%), liver dysfunction (27.27), hypothyroidism (24.24%), fever (24.24%), fatigue (21.21%), leukopenia (15.15%), hypertension (12.12%), platelet count decreased (6.06%), diarrhea (3.03%), and myocarditis (3.03%); one patient stopped treatment as myocarditis. The incidence of grade 3/4 adverse reactions was 9.09%. CONCLUSIONS: Regorafenib combined with toripalimab has a promising effect in the third-line and beyond treatment of advanced colorectal cancer. In the early use of combination therapy, excision of primary lesions can have a positive impact in regorafenib and toripalimab combination. This treatment-related adverse reactions are tolerant in combined therapy.
RESUMEN
BACKGROUND: Although pembrolizumab has shown clinical benefit in patients with small-cell lung cancer (SCLC), its actual efficacy in combination with a conventional chemotherapy drug has not been determined. We performed this study to discern the efficacy and risk of pembrolizumab in combination with chemotherapy as first-line therapy in SCLC patients. METHODS: We systematically searched the PubMed, ScienceDirect, Cochrane Library, Scopus, Ovid MEDLINE, Embase, Web of Science, and Google Scholar databases for relevant studies. The main outcomes were overall survival (OS) and progression-free survival (PFS). RESULTS: We identified 2980 articles and included 6 studies (5 were noncomparative open-label studies and 1 was a randomized controlled trial [RCT]) involving 396 patients in our meta-analysis. The pooled median OS (mOS) was 9.6 months (95% CI, 8.0-11.2), and the pooled median PFS (mPFS) was 4.2 months (95% CI, 2.2-6.1). The 1-year overall survival rate (OSR-1y) and 6-month progression-free survival rate (PFSR-6m) were 45.1% (95% CI, 33-57.2%) and 41.6% (95% CI, 24.3-59%), respectively. The objective response rate (ORR) was 38.8% (95% CI, 11.9-65.67%), disease control rate (DCR) was 69.30% (95% CI, 51.6-87.0%), complete response (CR) was 2.20% (95% CI, 0.8-3.7%), partial response (PR) was 34.70% (95% CI, 7.8-61.5%), and stable disease (SD) was 20.90% (95% CI, 9.1-32.6%). The grade 3-4 adverse effect (AE) rate was 20.88% (95% CI, 1.22-54.85%). The most common AEs were neutropenia (90.16%), anemia (53.21%), dysphagia (41.96%), platelet count decrease (34.87%), and esophagitis (32.89%); severe AEs included neutropenia, respiratory failure, pneumonitis, acute coronary syndrome, and colitis/intestinal ischemia. CONCLUSIONS: The combination of pembrolizumab with conventional chemotherapy is an effective therapeutic schedule with acceptable and manageable efficacy and toxicity in patients with SCLC. More high-quality and well-designed RCTs with large sample sizes are warranted to further validate our findings.

BACKGROUND: Whether topotecan plus platinum-based chemotherapy (TP) can achieve better results than etoposide plus platinum-based chemotherapy (EP) for small-cell lung cancer (SCLC) treatment is still controversial in clinical applications. We compared the effectiveness and toxicity of TP versus EP in this meta-analysis. METHODS: We searched PubMed, ScienceDirect, Cochrane Library, Scopus, Ovid MEDLINE, Embase, Web of Science, and Google Scholar databases for completeness one by one to find articles that met the conditions. Overall survival (OS) and progression-free survival (PFS) were analyzed as primary endpoints, and the objective response rate (ORR), disease control rate (DCR), and adverse events (AEs) were analyzed as secondary endpoints. RESULTS: In total, 2,480 articles were retrieved, and 6 randomized controlled trials (RCTs) contained results based on 1,924 patients. EP suggested conspicuously better OS (hazard ratio [HR]: 1.24 [1.02, 1.50], p = 0.03) and PFS (HR: 1.39 [1.17, 1.64], p = 0.0001) in SCLC treatment than TP, and ORR (54.1% vs. 60.2%, risk ratio [RR]: 0.77 [0.57, 1.06], p = 0.11), and DCR (74.9% vs. 84.4%, RR: 0.89 [0.79, 1.00], p = 0.06) tended to favor EP. Subgroup analysis of subsistence showed that EP had prominent benefit in the following subgroups: Asian, median age > 60, first-line treatment, ECOG 0-2, intravenous topotecan, and cisplatin. AEs illustrated that EP had conspicuously more anemia and alopecia than TP. CONCLUSIONS: Compared with TP, EP was noticeably better in OS and PFS, but EP was toxic in terms of anemia and alopecia. More multicenter, better planned RCTs are needed.

BACKGROUND AND STUDY AIMS: The diagnosis and surveillance of gastrointestinal stromal tumor (GIST) rely on pathology and immunochemistry (IHC), making it complicated and invasive. Noninvasive and convenient biomarkers of this disease need to be explored. The high specificity and sensitivity of IHC in detecting GIST 1 (DOG1) in biopsy indicate that it is also expressed in circulating tumor cells of the blood and may be an ideal biomarker for GIST. This aimed to detect the expression of DOG1 in peripheral blood cells (PBCs) and determine the relationship between DOG1 expression and clinical factors. PATIENTS AND METHODS: A total of 45 patients with GIST and 46 healthy controls (HCs) were recruited from the Second Affiliated Hospital of Nanchang University between December 2015 and June 2018. PBCs were isolated from peripheral venous blood by density gradient centrifugation. RNA was extracted from PBCs, and DOG1 mRNA was detected by quantitative reverse transcription polymerase chain reaction. DOG1 mRNA expression between GIST and HC was compared, and the relationship between clinical factors and DOG1 was also analyzed. RESULTS: DOG1 mRNA expression in PBCs was significantly higher in patients with GIST than that in HCs (3.326 [1.942-5.328] versus 0.744 [0.269-1.087], pâ¯<â¯0.01). The specificity and sensitivity were 88.9% and 89.1%, respectively (AUCâ¯=â¯0.912). Tumor diameter and risk of aggressive behavior were correlated with DOG1 expression, and other clinical factors (sex, age, location, number of phase-splitting cells, Ki-67 index, metastatic status) did not show any relationship with DOG1 expression. However, clinical factors, including tumor diameter and risk grade, were not independent factors in DOG1 expression when multivariate analysis was conducted. CONCLUSION: DOG1 expressions were significantly higher in patients with GIST than that in HCs. Tumor diameter and risk classification correlated with DOG1 expression but were not independent factors. DOG1 in PBCs is a promising noninvasive biomarker for GIST.

WHAT IS KNOWN AND OBJECTIVE: Although immune checkpoint inhibitors (ICIs) have shown clinical benefit for patients with non-small cell lung cancer (NSCLC), the efficacy of the combination of ICIs targeting different pathways is still unclear. We performed this meta-analysis to explore the efficacy of cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitor plus programmed cell death 1 receptor (PD-1)/programmed cell death receptor ligand 1 (PD-L1) inhibitor therapy (CP) for NSCLC IIIB/IV patients. METHODS: We systematically searched the main databases for relevant studies. The main outcomes were overall survival (OS) and progression-free survival (PFS). RESULTS AND DISCUSSION: We identified 3526 articles, including 5 randomized controlled trials (RCTs) (4377 patients), in our meta-analysis. We conducted two comparisons of CP versus chemotherapy or PD1/PDL1 inhibitor (P). Compared with chemotherapy, CP was more effective, with better OS (hazard ratio [HR]: 0.77, 95% CI [confidence interval]: 0.66-0.91; p = 0.001), better PFS (HR: 0.77, 95% CI: 0.70-0.85; p < 0.00001) and comparable objective response rate (ORR) (risk ratio [RR]: 1.27, 95% CI: 0.98-1.65; p = 0.07); in terms of toxicity, CP was comparable to chemotherapy across all-grade adverse events (AEs) (RR: 0.87, 95% CI: 0.73-1.03; p = 0.11) and grade 3-5 AEs (RR: 0.85, 95% CI: 0.63-1.14; p = 0.27). Compared with P, CP had no superiority in efficacy in terms of the OS (HR: 1.04, 95%CI: 0.86-1.24; p=0.70), PFS (HR: 0.95, 95%CI: 0.75-1.22; p = 0.70) and the ORR (RR: 1.07, 95% CI: 0.95-1.21; p = 0.27) but CP was more effective than P when PD-L1 expression was <1% (RR: 0.77,95%CI: 0.60-0.98; p = 0.04); in terms of toxicity, CP was associated with increased all-grade AEs (RR:1.07, 95% CI: 0.97-1.19; p = 0.18) and grade 3-5 AEs (RR:1.58, 95% CI: 1.21-2.07; p = 0.0008). WHAT IS NEW AND CONCLUSION: CP is a beneficial therapeutic schedule with longer PFS and OS than chemotherapy and has an acceptable, manageable grade 3-4 AE rate in IIIB/IV NSCLC. However, compared with P, CP results in better OS only in patients with PD-L1 expression <1%.

OBJECTIVE: Circular RNA (circRNA) plays a vital role in the development and progression of malignancies, however, the function of circRNAs in cholangiocarcinoma (CCA) remains unexplored. The aim of this study was to investigate circRNA expression in CCA versus para-cancer tissues, and elucidate any potential associated mechanisms. METHODS: Differential expression of circRNAs between CCA and para-cancer tissue was analysed by microarray hybridization, and validated by real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The downstream pathway was investigated using bioinformatics and qRT-PCR. RESULTS: Microarray hybridization revealed 10 circRNAs with > 3-fold increased expression versus para-cancer (circRNA_002172, circRNA_002144, circRNA_001588, circRNA_000166, circRNA_000585, circRNA_000167, circRNA_402608, circRNA_006853, circRNA_001589, circRNA_008882), and three circRNAs with > 3-fold decreased expression (circRNA_406083, circRNA_104940, circRNA_006349). CircRNA_000585 was shown by qRT-PCR to be upregulated in tumour versus paired para-cancer tissue from 15 patients with CCA. Bioinformatics analysis revealed a potential pathway comprising circRNA_000585/microRNA-615-5p/angiomotin (AMOT)/Yes associated protein 1 (YAP) in CCA. RT-PCR validation of crucial molecule expression showed downregulation of miR-615-5p, and upregulation of AMOT and YAP in CCA tumours. CONCLUSION: Multiple circRNAs are dysregulated in CCA. CircRNA_000585 is upregulated in CCA, and may function by a circRNA_000585/miR-615-5p/AMOT/YAP pathway, which may be a novel CCA pathway.

BACKGROUND: Researchers have not clearly determined whether adding aprepitant (ADH) to dexamethasone and one 5-HT3 receptor antagonist (DH) is clinically effective at preventing chemotherapy-induced nausea and vomiting (CINV) among patients with lung cancer (LC) treated with platinum-based chemotherapy (PBC). Therefore, we conducted a meta-analysis to examine the efficacy and safety of ADH and DH. METHODS: We searched the PubMed, ScienceDirect, Cochrane Library, and Scopus databases, among others, for relevant studies. The primary outcomes were the complete response (CR) and the no nausea rate (NNR). The secondary endpoints were the number of patients who needed rescue antiemetic treatment (RAT), adverse events (AEs), and the Functional Living Index Emesis (FLIE) score. RESULTS: We initially screened 2,118 articles; ultimately, four randomized controlled trials (RCTs) with 518 patients were included. The ADH group had a superior overall CR [risk ratio (RR): 1.16 (1.06, 1.27), P=0.002] and a lower number of patients who needed RAT [RR: 0.44 (0.29, 0.65), P<0.0001]. The ADH group also had a better overall NNR [RR: 1.11 (0.97, 1.26), P=0.12] and delayed CR [RR: 1.12 (0.97, 1.31), P=0.13]. No significant differences were observed in acute CR, acute NNR, or delayed NNR. In the subgroup analysis of the overall CR and NNR, ADH was superior in certain clinical characteristics (China, cisplatin-based chemotherapy, 2nd-generation 5-HT3 receptor antagonist, ADC <50%, and Eastern Cooperative Oncology Group (ECOG) score of 0-2). No significant differences in the AEs characterized as hematological or nonhematological toxicity were observed between the groups. CONCLUSIONS: Compared with DH, ADH appears to be superior at preventing CINV and achieving a better CR among patients with LC treated with PBC.

BACKGROUND: Whether necitumumab combined with platinum-based chemotherapy (NC) for treating stage IV non-small cell lung cancer (NSCLC) as a first-line treatment could enhance antitumor effectiveness compared with platinum-based chemotherapy alone (CA) treatment is still controversial. The antitumor effectiveness and toxicity of the two treatments were compared in this meta-analysis. METHODS: We searched in PubMed, ScienceDirect, Scopus, Web of Science, Ovid MEDLINE, the Cochrane Library, Embase, and Google Scholar to acquire applicable articles. The outcome indicators mainly included progression-free survival (PFS), overall survival (OS) and adverse effects (AEs). RESULTS: Eight articles based on 4 randomized controlled trials were obtained. The NC group had a longer PFS [95% confidence interval (CI): 0.84-0.99, P=0.03] and a higher disease control rate (DCR, 95% CI: 1.01-1.10, P=0.03) than those of the CA group. OS (95% CI: 0.85-1.01, P=0.09) and the objective response rate (ORR, 95% CI: 0.93-1.71, P=0.14) were similar in the NC and CA groups. Nevertheless, in both quantity and extent, the NC treatment had more severe skin rash, hypomagnesemia, and venous thromboembolism than those of the CA treatment. Subanalysis suggested that the advantage of OS was more obvious in the NC group than that in the CA group in patients with high epidermal growth factor receptor (EGFR) expression. CONCLUSIONS: With a longer PFS and a higher DCR, NC treatment seemed to be more suitable for treating stage IV NSCLC as first-line therapy, especially for those with high EGFR expression, but its AEs could not be ignored.

The complications caused by early closure (EC) or late closure (LC) after temporary ileostomy in rectal cancer patients have not been compared systematically. We conducted this meta-analysis to explore the details surrounding this issue, based on a search of PubMed, ScienceDirect, Scopus, Web of Science, Ovid MEDLINE, the Cochrane Library, Embase, and Google Scholar. The comparative indices included total complications, severe complications, and various individual complications before or after closure. Four randomized-controlled trials (RCTs), including the EASY trial, were analyzed, involving a collective total of 324 patients. EC tended to result in more postoperative complications than LC for rectal cancer patients with temporary ileostomy. This difference was mainly embodied in wound complications. Nevertheless, LC resulted in more complications than EC before closure, such as leakage outside the appliance bag and skin irritation. There was no obvious difference in severe postoperative complications or medical complications. With fewer overall and wound-related complications, LC tended to be more suitable than EC for rectal cancer patients with a temporary ileostomy; however, the complications before closure should also be considered.

BACKGROUND: Stereotactic body radiotherapy (SBRT) superseded conventional radiotherapy (CRT) for the treatment of patients with inoperable early stage non-small cell lung cancer (NSCLC) over a decade ago. However, the direct comparisons of the outcomes of SBRT and CRT remain controversial. This meta-analysis was performed to compare the survival and safety of SBRT and CRT in patients with inoperable stage I NSCLC. METHODS: We systematically searched the Cochrane Library, Embase, PubMed, Web of Science, Ovid MEDLINE, ScienceDirect, Scopus and Google Scholar for relevant articles. Overall survival (OS), progression-free survival (PFS), lung cancer-specific survival (LCSS), local control rate (LCR) and adverse effects (AEs) were the primary outcomes. RESULTS: We identified 11,110 articles, 17 of which were eventually included in this study; these 17 articles had 17,973 patients (SBRT: 7395; CRT: 10,578). Compared to CRT for the treatment of inoperable stage I NSCLC, SBRT had superior survival in terms of OS (hazard ratio [HR]: 0.66, 95% confidence interval [CI]: 0.62-0.70, Pâ<â.00001), LCSS (HR: 0.42 [0.35-0.50], Pâ<â.00001), and PFS (HR: 0.34 [0.25-0.48], Pâ<â.00001). The 4-year OS rate (OSR); 4-year LCSS rate (LCSSR); 3-year local control rate (LCR); 5-year PFS rate (PFSR) with SBRT were all higher than those with CRT. With regard to all-grade AEs, the SBRT group had a significantly lower rate of dyspnea, esophagitis and radiation pneumonitis; no significant difference was found in grade 3-5 AEs (risk ratio [RR]: 0.68 [0.30-1.53], Pâ=â.35). CONCLUSIONS: With better survival and a lower rate of dyspnea, esophagitis and radiation pneumonitis than CRT, SBRT appears to be more suitable for patients with inoperable stage I NSCLC.

BACKGROUND: Talc pleurodesis (TP) and indwelling pleural catheter (IPC) are used for the management of malignant pleural effusion (MPE). Our meta-analysis was conducted to assess the efficacy and safety of both treatments among patients with MPE. METHODS: We acquired pertinent randomized controlled trials (RCTs) by searching PubMed, ScienceDirect, the Cochrane Library, Scopus, Ovid Medline, Embase, Web of Science, and Google Scholar. The endpoints included survival, pleurodesis rates, total drainage, further pleural interventions, hospital days, symptoms, quality of life (QoL), and complications. RESULTS: We included four high-quality RCTs. Both treatments were effective among patients with MPE and no previous pleurodesis, with comparable survival and equivalent relief of breathlessness. Additionally, the TP group had higher pleurodesis rates, less total drainage, and fewer all-grade complications (including catheter blockage and cellulitis). However, patients in the TP group had more pleural procedures and relatively longer hospital stays. Additionally, no apparent difference was detected in QoL. CONCLUSIONS: TP has better pleurodesis rates, less total drainage, and fewer all-grade complications. However, TP has more pleural procedures and is not feasible for patients with trapped lungs. IPC has fewer further pleural interventions and shorter hospital stays. However, IPC has the nuisance of long-term in situ draining.

BACKGROUND: Whether erlotinib plus tivantinib (ET) can achieve better clinical benefits than erlotinib plus placebo (EP) among participants with previously treated advanced non-small-cell lung cancer (NSCLC) is still disputed. We conducted a meta-analysis to evaluate the anticancer efficacy and safety of both regimens. MATERIALS AND METHODS: We searched for pertinent trials at PubMed, ScienceDirect, The Cochrane Library, Scopus, Ovid MEDLINE, Embase, Web of Science, and Google Scholar. Endpoints mainly included progression-free survival (PFS), overall survival (OS), objective response rate (ORR), disease control rate (DCR), and adverse events (AEs). RESULTS: We included 1522 patients who previously received ≥1 systemic anti-cancer regimen that included platinum-based chemotherapy. Although ET failed to improve OS (hazard ratio [HR] = 0.91, 95% confidence interval [CI]: 0.75-1.10, Pâ=â.35), the ET group had better PFS (HRâ=â0.73, 95% CI: 0.67-0.80, Pâ<â.00001), higher ORR (HRâ=â1.50, 95% CI: 1.06-2.12, Pâ=â.02), and better DCR (HRâ=â1.38, 95% CI: 1.20-1.59, Pâ<â.00001). Our subanalysis suggested that the ET group may have had better OS among patients with high Mesenchymal to epithelial transition factor (MET) expression (HRâ=â0.76, 95% CI: 0.58-0.99, Pâ=â.04) and good VeriStrat (HRâ=â0.88, 95% CI: 0.83-0.93, Pâ<â.0001). AEs were roughly similar except for specific hematological toxicities: more neutropenia and febrile neutropenia were observed in the ET group, both of which should not be overlooked. CONCLUSIONS: ET appears to be superior to EP due to better PFS and higher response rates, especially for patients with high MET expression and good VeriStrat. The greater hematological toxicity in the ET regimen is non-negligible.
