Abstract
IMPORTANCE Various first-line chemotherapy treatment regimens for patients with metastatic pancreatic cancer have been approved in Japan, including gemcitabine (GEM); fluorouracil, leucovorin, irinotecan, and oxaliplatin combination (FOLFIRINOX); GEM plus albumin-bound paclitaxel (GEM+NPTX), and S-1 (tegafur + gimeracil + oteracil). However, direct comparisons of these chemotherapy regimens are limited. OBJECTIVE To assess the short-term and long-term outcomes associated with first-line chemotherapy regimens for metastatic pancreatic cancer compared with chemotherapy regimens recommended in Japanese guidelines. DATA SOURCES In this systematic review and network meta-analysis, the bibliographic databases PubMed, Cochrane Library, and Web of Science, as well as medical journals published between January 1, 2002, and December 31, 2018, were searched for clinical trials comparing chemotherapy regimens. STUDY SELECTION Randomized 2-arm clinical trials evaluating first-line chemotherapy for advanced or metastatic pancreatic cancer were included. DATA EXTRACTION AND SYNTHESIS The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Extension Statement for Reporting of Systematic Reviews Incorporating Network Meta-analyses of Health Care Interventions was followed for data abstractions. Data were pooled using a random-effects model. The SIGN 50 Quality Assessment Instrument was used to assess the risk of bias and overall study quality of the selected trials. MAIN OUTCOMES AND MEASURES The primary end point was overall survival (OS), and the secondary end point was progression-free survival (PFS) compared with GEM for first-line chemotherapy for metastatic pancreatic cancer. The Kaplan-Meier curve of GEM from the literature and the estimated hazard ratios (HRs) were used to model the long-term associations to calculate the area under the curve (AUC) (person-months) for OS and PFS of each chemotherapy. Sensitivity analyses with multiple functional models were conducted to confirm the long-term estimations. RESULTS A total of 22 regimens (25 studies) for OS and a total of 18 regimens (21 studies) for PFS were identified from literature. The total number of participants was 10 186, with 5856 male (57.5%) and 4330 female (42.5%). The FOLFIRINOX and GEM+NPTX regimens were associated with reduction in the risk of death, with an HR of 0.57 (95% CI, 0.41-0.79) and 0.72 (95% CI, 0.55-0.95) compared with GEM, respectively. The curve estimation also showed that FOLFIRINOX had the largest AUC for survival at 15.49 person-months (range, 13.84-15.51 person-months), followed by GEM+NPTX with 12.36 person-months (range, 10.98-12.59 person-months), GEM+ERLO with 10.84 person-months (range, 9.66-11.23 person-months), S-1 with 8.44 person-months (range, 8.26-9.74 person-months), and GEM with 8.10 person-months (range, 7.93-9.38 person-months). CONCLUSIONS AND RELEVANCE The results of this network meta-analysis support the relative short-term and long-term outcomes associated with first-line chemotherapy for metastatic pancreatic cancer used clinically in Japan.

BMC cancer. 2022;(1):216
Abstract
OBJECTIVE Neuroblastoma is a common extracranial solid tumor of childhood. Recently, multiple treatments have been practiced including Iodine-131-metaiodobenzylguanidine radiation (131I-MIBG) therapy. However, the outcomes of efficacy and safety vary greatly among different studies. The aim of this meta-analysis is to evaluate the efficacy and safety of 131I-MIBG in the treatment of neuroblastoma and to provide evidence and hints for clinical decision-making. METHODS Medline, EMBASE database and the Cochrane Library were searched for relevant studies. Eligible studies utilizing 131I-MIBG in the treatment of neuroblastoma were included. The pooled outcomes (response rates, adverse events rates, survival rates) were calculated using either a random-effects model or a fixed-effects model considering of the heterogeneity. RESULTS A total of 26 clinical trials including 883 patients were analyzed. The pooled rates of objective response, stable disease, progressive disease, and minor response of 131I-MIBG monotherapy were 39%, 31%, 22% and 15%, respectively. The pooled objective response rate of 131I-MIBG in combination with other therapies was 28%. The pooled 1-year survival and 5-year survival rates were 64% and 32%. The pooled occurrence rates of thrombocytopenia and neutropenia in MIBG monotherapy studies were 53% and 58%. In the studies of 131I-MIBG combined with other therapies, the pooled occurrence rates of thrombocytopenia and neutropenia were 79% and 78%. CONCLUSION 131I-MIBG treatment alone or in combination of other therapies is effective on clinical outcomes in the treatment of neuroblastoma, individualized 131I-MIBG is recommended on a clinical basis.

Abstract
BACKGROUND It is necessary to systematically evaluate the clinical efficacy and safety of bevacizumab (BEV) combined with 5-fluorouracil + leucovorin + oxaliplatin (FOLFOX) regimen in the treatment of advanced colorectal cancer. METHODS We searched the PubMed et al databases for randomized controlled trials (RCTs) on the BEV combined with the FOLFOX regimen in the treatment of advanced colorectal cancer up to January 20, 2021. The Cochrane Collaborations' risk of bias tool was used for the quality assessment of included RCTs. Revman5.3 software was used for meta-analysis. RESULTS Eleven RCTs with a total of 3178 patients with advanced colorectal cancer were included, meta-analysis results showed that the objective response rate (odds ratio [OR] = 3.15, 95% confidence intervals [CI]: 2.25-4.40, P < .001) and cancer control rate (OR = 2.73, 95% CI: 1.91-3.90, P < .001) of BEV + FOLFOX were higher than that of FOLFOX group. And the incidence of gastrointestinal adverse reactions (OR = 1.29, 95% CI: 1.07-1.55, P = .008) in the BEV + FOLFOX group was higher than that of the FOLFOX group, there were no significant differences in the incidence of leukopenia (OR = 1.04, 95% CI: 0.72-1.50, P = .83), hypertension (OR = 3.92, 95% CI: 0.81-18.88, P = .09) and neurotoxicity (OR = 1.00, 95% CI: 0.8-1.27, P = .98) between the 2 groups. CONCLUSION BEV combined with the FOLFOX regimen is more effective than the FOLFOX regimen alone in the treatment of advanced colorectal cancer, but it may also increase the risk of gastrointestinal adverse reactions.

Scientific reports. 2021;(1):20152
Abstract
Treatment outcomes between FOLFIRINOX (5-fluorouracil, leucovorin, irinotecan, and oxaliplatin) and GNP (gemcitabine with albumin-bound paclitaxel) as first-line chemotherapy regimens for metastatic pancreatic cancer (PC) were assessed according to ethnic groups categorized as Western or Asian subgroups. PubMed, EMBASE, and Cochrane library were searched. Thirteen studies were eligible in this meta-analysis. Overall survival was not significantly different between FOLFIRINOX and GNP (HR 1.00, 95% CI 0.83-1.20, P = 0.990). However, the Western subgroup showed a higher survival benefit for FOLFIRINOX over GNP (HR 0.84, 95% CI 0.74-0.95, P = 0.006) whereas the Asian subgroup showed the survival benefit for GNP over FOLFIRINOX (HR 1.29, 95% CI 1.03-1.60, P = 0.030). Progression free survival was not significantly different between the two regimens in the Western subgroup (HR 1.01, 95% CI 0.84-1.20, P = 0.950) and the Asian subgroup (HR 1.13, 95% CI 0.97-1.33, P = 0.110). Occurrence of febrile neutropenia was significantly higher in FOLFIRINOX at both ethnic subgroups; however, that of peripheral neuropathy was significantly higher only in GNP of the Asian subgroup. Therefore, pharmacoethnicity might be a factor worth considering when deciding on a frontline chemotherapeutic regimen although the overall survival was not significantly different between FOLFIRINOX and GNP for metastatic PCs.

Abstract
FOLFIRINOX, a combination of chemotherapy drugs (Fluorouracil, Oxaliplatin, Irinotecan -FOI), provides the best clinical benefit in pancreatic ductal adenocarcinoma (PDAC) patients. In this study we explore the role of miRNAs (MIR) as modulators of chemosensitivity to identify potential biomarkers of response. We find that 41 and 84 microRNA inhibitors enhance the sensitivity of Capan1 and MiaPaCa2 PDAC cells respectively. These include a MIR1307-inhibitor that we validate in further PDAC cell lines. Chemotherapy-induced apoptosis and DNA damage accumulation are higher in MIR1307 knock-out (MIR1307KO) versus control PDAC cells, while re-expression of MIR1307 in MIR1307KO cells rescues these effects. We identify binding of MIR1307 to CLIC5 mRNA through covalent ligation of endogenous Argonaute-bound RNAs cross-linking immunoprecipitation assay. We validate these findings in an in vivo model with MIR1307 disruption. In a pilot cohort of PDAC patients undergoing FOLFIRONX chemotherapy, circulating MIR1307 correlates with clinical outcome.

Abstract
BACKGROUND Limited treatment options are available in chemotherapy-refractory metastatic colorectal cancer (mCRC). The objective was to conduct a systematic literature review (SLR) and exploratory network meta-analysis (NMA) to compare the tolerability and effectiveness of SIRT with Y-90 resin microspheres, regorafenib, TAS-102 (trifluridine/tipiracil), and best supportive care (BSC) as third-line treatment in patients with mCRC. METHODS An SLR was conducted to identify studies comparing two or more of the treatments and reporting overall survival (OS), progression-free survival, tumor response, or adverse event (AE) incidence. An exploratory NMA was conducted to compare hazard ratios (HRs) for OS using Markov chain Monte Carlo (MCMC) techniques. RESULTS Seven studies were identified in the SLR: two double-blind randomized-controlled trials (RCT) for each drug, one open-label RCT, and two non-randomized comparative studies for SIRT. Patient selection criteria differed between studies, with SIRT studies including patients with liver-dominant colorectal metastases. Nausea and vomiting were more frequent with TAS-102 than regorafenib or SIRT; diarrhea was more common with TAS-102 and regorafenib than SIRT. The exploratory NMA suggested that all active treatments improved OS, with HRs of 0.48 (95% CrI 0.30-0.78) for SIRT with Y-90 resin microspheres, 0.63 (0.38-1.03) for TAS-102, and 0.67 (0.40-1.08) for regorafenib each compared to BSC. CONCLUSIONS Regorafenib, TAS-102 and SIRT using Y-90 resin microspheres are more effective than BSC in third-line treatment of mCRC; however, study heterogeneity made comparisons between active treatments challenging. SIRT is a viable treatment for third-line mCRC and its favorable AE profile should be considered in the therapeutic decision-making process.

Cancer medicine. 2020;(4):1419-1429
Abstract
Early identification of metastatic or recurrent colorectal cancer (CRC) patients who will be sensitive to FOLFOX (5-FU, leucovorin and oxaliplatin) therapy is very important. We performed microarray meta-analysis to identify differentially expressed genes (DEGs) between FOLFOX responders and nonresponders in metastatic or recurrent CRC patients, and found that the expression levels of WASHC4, HELZ, ERN1, RPS6KB1, and APPBP2 were downregulated, while the expression levels of IRF7, EML3, LYPLA2, DRAP1, RNH1, PKP3, TSPAN17, LSS, MLKL, PPP1R7, GCDH, C19ORF24, and CCDC124 were upregulated in FOLFOX responders compared with nonresponders. Subsequent functional annotation showed that DEGs were significantly enriched in autophagy, ErbB signaling pathway, mitophagy, endocytosis, FoxO signaling pathway, apoptosis, and antifolate resistance pathways. Based on those candidate genes, several machine learning algorithms were applied to the training set, then performances of models were assessed via the cross validation method. Candidate models with the best tuning parameters were applied to the test set and the final model showed satisfactory performance. In addition, we also reported that MLKL and CCDC124 gene expression were independent prognostic factors for metastatic CRC patients undergoing FOLFOX therapy.

Efficacy and safety of high-dose vs low-dose leucovorin in patients with colorectal cancer: systematic review and meta-analysis.
Hsu, CY, Chen, CY, Lin, YM, Tam, KW
Colorectal disease : the official journal of the Association of Coloproctology of Great Britain and Ireland. 2020;(1):6-17
Abstract
AIM: The clinical benefits of a combination of leucovorin and fluorouracil have been established in the treatment of colorectal cancer. Due to a leucovorin shortage in 2008, many institutions revised their protocols to reduce the dose of leucovorin. After the shortage was resolved, some hospitals still maintained their modified protocols. Thus, we conducted a systematic review to evaluate the efficacy and safety of low- vs high-dose leucovorin in the treatment of colorectal cancer. METHOD The PubMed, Embase and Cochrane databases were searched for studies published before May 2019. The meta-analysis was performed to estimate the pooled effect sizes by using a random effect model. The primary outcomes were median survival time and tumour response rate. Secondary outcomes were haematological and nonhaematological toxicities. RESULTS Eight randomized controlled trials and four retrospective studies were reviewed. The pooled median survival time was similar between the two dose levels (standard mean difference -0.06, 95% CI -0.19 to 0.08). The pooled tumour response rate was comparatively higher in the high-dose leucovorin regimen (OR 0.81; 95% CI 0.55-1.18). No statistically significant difference was found between the haematological and nonhaematological toxicities of the two groups. However, there were fewer diarrhoea events in the low-dose leucovorin regimen. CONCLUSION Low-dose leucovorin regimens seemed feasible approaches for colorectal cancer treatment when the shortage happened, because both regimens manifested comparable outcomes in survival time and tumour response rate.

Abstract
OBJECTIVE The aim of the present network meta-analysis (NMA) was to explore the comparative effectiveness and safety of different Chinese herbal injections (CHIs) combined with the FOLFOX regimen versus FOLFOX alone for colorectal cancer (CRC). METHODS A comprehensive search for randomized controlled trials (RCTs) was performed with regard to different CHIs for treating CRC in several electronic databases up to July 2016. The quality assessment of the included RCTs was conducted according to the Cochrane risk of bias tool. Standard pair-wise and Bayesian NMA were designed to compare the effectiveness and safety of different CHIs combined with the FOLFOX regimen by utilizing WinBUGS 1.4.3 and Stata 13.1 software, simultaneously. RESULTS Initially, a total of 820 citations were retrieved through comprehensive searching, and 60 eligible articles involving 4849 participants and 14 CHIs were ultimately included. The results of the current evidence indicated that the FOLFOX regimen combined with Delisheng, Kanglaite, Shenqifuzheng, or Aidi injections were associated with the most favorable clinical efficacy compared with the FOLFOX regimen alone. Additionally, the FOLFOX regimen combined with Delisheng, Xiaoaiping, Lentinan, Kangai, Shenqifuzheng, or Aidi injections improved performance status among patients with CRC. CONCLUSIONS The results of cluster analysis demonstrated that the combination of Compound matrine injection and FOLFOX regimen was associated with more preferable and beneficial outcomes than other CHIs groups. Nevertheless, the additional results from multicenter trials and high-quality studies will be pivotal for supporting our findings.

Cao, Y, Wan, N, Liang, Z, Xie, J, Wang, S, Lin, T, Zhang, T, Jiang, J
Clinical lymphoma, myeloma & leukemia. 2019;(8):e478-e488
Abstract
Many new regimens have been applied to newly diagnosed transplant-ineligible multiple myeloma, but no head-to-head research has been performed to compare the efficacy of these treatments. Currently lenalidomide plus dexamethasone (Rd) is one of the standard treatments. Our aim was to make a comparison of these treatments to Rd by a network meta-analysis. We performed a systematic review and network meta-analysis. We searched PubMed, Embase, and the Cochrane Library for articles published from January 1, 1988, to April 26, 2018, as well as research presented at 5 international conferences (American Society of Clinical Oncology, American Society of Hematology, European Hematology Association, European Society of Medical Oncology, and International Myeloma Working Group) between January 2015 and December 2018. Our interest outcomes were hazard ratios (HRs) for progression-free survival (PFS) and overall survival (OS). Bayesian fixed-effects mixed-treatment comparisons were used for this study. A total of 23 articles describing 10,401 participants were included for this network meta-analysis. Lenalidomide and dexamethasone plus daratumumab (HR, 0.57; 95% credible interval [CrI], 0.43-0.73), daratumumab plus bortezomib, melphalan, and prednisone (HR, 0.59; 95% CrI, 0.36-0.91), and the combination of bortezomib with lenalidomide and dexamethasone (RVd) (HR, 0.72, 95% CrI, 0.56-0.90) all showed significant effect compared to Rd for PFS. RVd demonstrated significant benefit compared to Rd (HR, 0.72; 95% CrI, 0.53-0.96) for OS. Our study results suggested that lenalidomide and dexamethasone plus daratumumab; daratumumab plus bortezomib, melphalan, and prednisone; and RVd showed better efficacy than Rd in PFS; and RVd showed better efficacy than Rd in OS in patients with newly diagnosed transplant-ineligible multiple myeloma in the absence of head-to-head research.
