e16549 Background: Numerous immunotherapy (IO) and vascular endothelial growth factor receptor inhibitors (VEGFI) options are approved for first-line (1L) treatment of mRCC. We performed a systematic review and meta-analysis to compare the oncologic outcomes and adverse events of these therapies. Methods: We searched databases for randomized controlled trials (RCT) evaluating agents that are currently FDA-approved or on the NCCN compendium for 1L mRCC, with sunitinib (S) as a comparator. Primary outcomes were overall survival (OS), progression-free survival (PFS), overall response rate (ORR), and grade 3 and 4 (G3/G4) adverse events (AEs). We attempted network meta-analysis (NMA) to estimate relative effects of the comparative treatments. Survival outcomes were summarized using hazard ratios (HR). In the case that the HR was not reported but a Kaplan-Meier curve was available, the curve was digitized using Engauge Digitizer software. A frequentist fixed-effects NMA model was applied to each outcome. Results: 798 articles were identified, of which 47 were eligible for full text screening, and 8 were included for evidence synthesis. Eight RCTs recruiting a total of 5,565 pts with advanced or metastatic treatment-naïve RCC were included. The summary of all included studies is reported in Table 1. Ordered from the most to least effective, treatments with greatest mOS benefit include Nivolumab plus Cabozantinib (NC), Pembrolizumab plus Axitinib (PA), and Nivolumab plus Ipilimumab (NI); treatments with greatest mPFS benefit include Cabozantinib (C), NC, and Avelumab plus Axitinib (AA); treatments with the highest ORR include C, NC, and AA. Ordered from least to most toxic, treatments with G3/G4 AEs less frequent than sunitinib include Pazopanib (P), NI, and AA. Conclusions: OS generally favored IO-IO or IO-VEGFI combinations, while PFS and ORR favored single agent C or IO-VEGFI. The lowest risks of G3/G4 AE were seen with P or IO-IO. IO-VEGFI combinations had similar risks for G3/G4 AE. Longer real-world follow-up is needed. We recognize the limitations of cross-trial comparisons, but sought a summative view of the current data.[Table: see text]

Background. Randomized studies have shown different magnitude of bevacizumab benefit in the treatment of advanced breast cancer. Regulatory agencies have modified bevacizumab treatment indications across different regions. In this study, we perform a meta-analysis of phase III studies aiming to interrogate the magnitude of bevacizumab benefit for the treatment of first-line HER2-negative metastatic breast cancer (MBC).Methods. Data from studies E2100, AVADO and RIBBON-1 were used to calculate the benefit of bevacizumab in terms of tumor overall response rate (ORR), progression-free survival (PFS), overall survival (OS), and toxicities. Combined statistical estimates of hazard ratios (HR) and odds ratios were calculated using fixed-effects or random-effects models.Results. A total of 2,695 patients were evaluated. Combining bevacizumab with different chemotherapy backbones resulted in a 30% risk reduction of PFS events (HR = 0.70; 95% confidence interval [CI], 0.57–0.86) and increased ORR (odds ratio 1.81; 95% CI, 1.53–2.14). No OS benefit could be demonstrated (HR = 0.95; 95% CI, 0.85–1.06). Bevacizumab significantly increased the incidence of adverse events such as proteinuria, hypertension and cardiovascular events.Conclusions. Bevacizumab combined with chemotherapy in the first-line treatment of MBC significantly improved ORR and PFS, but also increased grade 3-4 toxicities. No significant OS advantage was observed.

<b><i>Introduction:</i></b> Several endoscopic methods can be employed to manage post-bariatric leaks. However, endoluminal vacuum therapy (EVT) and endoscopic internal drainage (EID) are relatively new methods, and studies regarding these methods are scarce. We performed a systematic review of the literature and a meta-analysis to evaluate the efficacy of EVT and EID. <b><i>Methods:</i></b> Databases were searched for eligible studies. The clinical success of leak closure was the primary outcome of interest. A proportional meta-analysis was performed for pooling the primary outcome using a fixed-effects model. A meta-analysis or descriptive analysis of other outcomes was performed based on the data availability. <b><i>Results:</i></b> Data from 3 EVT and 10 EID studies (<i>n</i> = 279) were used for evidence synthesis. The leak closure rates (95% confidence interval [CI]) of EVT and EID were 85.2% (75.1%–95.4%) and 91.6% (88.1%–95.2%), respectively. The corresponding mean treatment durations (95% CI) were 28 (2.4–53.6) and 78.4 (50.1–106.7) days, respectively. However, data about other outcomes were extremely limited; thus, a pooled analysis could not be performed. <b><i>Conclusions:</i></b> Both EVT and EID were effective when used as the first-line treatment for post-bariatric leaks. However, larger studies must be conducted to compare the efficacy of the 2 interventions.

PurposePazopanib is an oral, multikinase inhibitor of vascular endothelial growth factor receptor (VEGFR) -1/-2/-3, platelet-derived growth factor receptor (PDGFR) -α/-β, and c-Kit. Preclinical and clinical studies support VEGFR and PDGFR as targets for advanced ovarian cancer treatment. This study evaluated the role of pazopanib maintenance therapy in patients with ovarian cancer whose disease did not progress during first-line chemotherapy.Patients and MethodsNine hundred forty patients with histologically confirmed cancer of the ovary, fallopian tube, or peritoneum, International Federation Gynecology Obstetrics (FIGO) stages II-IV, no evidence of progression after primary therapy consisting of surgery and at least five cycles of platinum-taxane chemotherapy were randomized 1:1 to receive pazopanib 800 mg once per day or placebo for up to 24 months. The primary end point was progression-free survival by RECIST 1.0 assessed by the investigators.ResultsMaintenance pazopanib prolonged progression-free survival compared with placebo (hazard ratio [HR], 0.77; 95% CI, 0.64 to 0.91; P = .0021; median, 17.9 v 12.3 months, respectively). Interim survival analysis based on events in 35.6% of the population did not show any significant difference. Grade 3 or 4 adverse events of hypertension (30.8%), neutropenia (9.9%), liver-related toxicity (9.4%), diarrhea (8.2%), fatigue (2.7%), thrombocytopenia (2.5%), and palmar-plantar erythrodysesthesia (1.9%) were significantly higher in the pazopanib arm. Treatment discontinuation related to adverse events was higher among patients treated with pazopanib (33.3%) compared with placebo (5.6%).ConclusionPazopanib maintenance therapy provided a median improvement of 5.6 months (HR, 0.77) in progression-free survival in patients with advanced ovarian cancer who have not progressed after first-line chemotherapy. Overall survival data to this point did not suggest any benefit. Additional analysis should help to identify subgroups of patients in whom improved efficacy may balance toxicity (NCT00866697).

AbstractObjectiveTo compare the efficacy and safety of first line treatments for patients with advanced epidermal growth factor receptor (EGFR) mutated non-small cell lung cancer (NSCLC).DesignSystematic review and network meta-analysis.Data sourcesPubMed, Embase, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and several international conference databases, from inception to 20 May 2019.Eligibility criteria for selecting studiesPublished and unpublished randomised controlled trials comparing two or more treatments in the first line setting for patients with advanced EGFR mutated NSCLC were included in a bayesian network meta-analysis. Eligible studies reported at least one of the following clinical outcome measures: progression free survival, overall survival, objective response rate, and adverse events of grade 3 or higher.Results18 eligible trials involved 4628 patients and 12 treatments: EGFR tyrosine kinase inhibitors (TKIs; osimertinib, dacomitinib, afatinib, erlotinib, gefitinib, and icotinib), pemetrexed based chemotherapy, pemetrexed free chemotherapy, and combination treatments (afatinib plus cetuximab, erlotinib plus bevacizumab, gefitinib plus pemetrexed based chemotherapy, and gefitinib plus pemetrexed). Consistent with gefitinib plus pemetrexed based chemotherapy (hazard ratio 0.95, 95% credible interval 0.72 to 1.24), osimertinib showed the most favourable progression free survival, with significant differences versus dacomitinib (0.74, 0.55 to 1.00), afatinib (0.52, 0.40 to 0.68), erlotinib (0.48, 0.40 to 0.57), gefitinib (0.44, 0.37 to 0.52), icotinib (0.39, 0.24 to 0.62), pemetrexed based chemotherapy (0.24, 0.17 to 0.33), pemetrexed free chemotherapy (0.16, 0.13 to 0.20), afatinib plus cetuximab (0.44, 0.28 to 0.71), and gefitinib plus pemetrexed (0.65, 0.46 to 0.92). Osimertinib and gefitinib plus pemetrexed based chemotherapy were also consistent (0.94, 0.66 to 1.35) in providing the best overall survival benefit. Combination treatments caused more toxicity in general, especially erlotinib plus bevacizumab, which caused the most adverse events of grade 3 or higher. Different toxicity spectrums were revealed for individual EGFR-TKIs. Subgroup analyses by the two most common EGFR mutation types indicated that osimertinib was associated with the best progression free survival in patients with the exon 19 deletion, and gefitinib plus pemetrexed based chemotherapy was associated with the best progression free survival in patients with the Leu858Arg mutation.ConclusionsThese results indicate that osimertinib and gefitinib plus pemetrexed based chemotherapy were associated with the best progression free survival and overall survival benefits for patients with advanced EGFR mutated NSCLC, compared with other first line treatments. The treatments resulting in the best progression free survival for patients with the exon 19 deletion and Leu858Arg mutations were osimertinib and gefitinib plus pemetrexed based chemotherapy, respectively.Systematic review registrationPROSPERO CRD42018111954.

Purpose Taxanes (paclitaxel or docetaxel) have been sequenced or combined with anthracyclines (doxorubicin or epirubicin) for the first-line treatment of advanced breast cancer. This meta-analysis uses data from all relevant trials to detect any advantages of taxanes in terms of tumor response, progression-free survival (PFS), and survival. Patients and Methods Individual patient data were collected on eight randomized combination trials comparing anthracyclines + taxanes (+ cyclophosphamide in one trial) with anthracyclines + cyclophosphamide (+ fluorouracil in four trials), and on three single-agent trials comparing taxanes with anthracyclines. Combination trials included 3,034 patients; single-agent trials included 919 patients. Results Median follow-up of living patients was 43 months, median survival was 19.3 months, and median PFS was 7.1 months. In single-agent trials, response rates were similar in the taxanes (38%) and in the anthracyclines (33%) arms (P = .08). The hazard ratios for taxanes compared with anthracyclines were 1.19 (95% CI, 1.04 to 1.36; P = .011) for PFS and 1.01 (95% CI, 0.88 to 1.16; P = .90) for survival. In combination trials, response rates were 57% (10% complete) in taxane-based combinations and 46% (6% complete) in control arms (P < .001). The hazard ratios for taxane-based combinations compared with control arms were 0.92 (95% CI, 0.85 to 0.99; P = .031) for PFS and 0.95 (95% CI, 0.88 to 1.03; P = .24) for survival. Conclusion Taxanes were significantly worse than single-agent anthracyclines in terms of PFS, but not in terms of response rates or survival. Taxane-based combinations were significantly better than anthracycline-based combinations in terms of response rates and PFS, but not in terms of survival.

335 Background: Systematic reviews are outdated quickly when the evidence is rapidly evolving as the process is laborious and there is little incentive for primary author team of an index SRMA to update the evidence. Consequently, there is an epidemic of redundant SRMAs performed by different teams—sometimes with conflicted results—for treatment of first line mRCC. Methods: We have created a living, interactive systematic review (LISR)and network meta-analysis(LINMA) for the treatment of first line mRCC using an Artificial intelligence (AI) assisted framework for evidence synthesis (Living, Interactive evidence synthesis framework) (LIvE) . The framework is implemented in five-layered architecture (application layer, shared module layer, core service layer, middleware layer, and storage layer) which work together to automate the identification of new studies and analysis and semi-automate the screening and data extraction. Dynamic features such as interactive tables, figures and evidence maps are enabled using Python and JavaScript programming languages. Results: We have maintained a living, interactive evidence profile for the first line treatment mRCC since September 2019 ( LIVING WEBSITE) . Living search strategy identifies new studies as they become available. As of October 13, 2020 LISR, includes data 14 clinical trials ( PRISMA ). Baseline characteristics are summarized in an interactive table ( TABLE) . Cabozantinib& Nivolumab (Cabo-Nivo) is the highest ranked drug for improving Overall Response (OR), Progression Free Survival (PFS) and Overall Survival (OS) whereas Ipilimumab in combination with Nivolumab (Ipi-Nivo) is highest ranked drug for achieving complete response (CR). Ipi-Nivo and Atezolizumab & Bevacizumab (Ate-Bev) ranked highest and Cabo-Nivo ranked lowest for treatment related Adverse events (TRAEs). Results of network meta-analysis are summarized as interactive tables and plots ( NMA ), summary of findings tables ( MULTIPLE COMAPRISONS ) and evidence maps ( MAP ). Conclusions: LISRs can potentially reduce redundancy, increase transparency, reproducibility, enable shared-decision making (at a guideline level, or in a patient-clinician dyad) and support living guidelines.

9061 Background: Clinical efficacy of single agent anti-PD-1/PD-L1 in patients with Non-Small-Cell-Lung-Cancer (NSCLC) that were PD-L1 negative or < 1% is controversial. Recent studies have evaluated the combination of anti-PD-1/PD-L1 to chemotherapy (CT) for this population in the first line setting. Methods: We performed a meta-analysis (MA) of randomized trials that compared PD-1/PD-L1 inhibitor plus CT with CT alone in first line of treatment for advanced NSCLC. The outcomes included overall survival (OS), progression-free survival (PFS) and objective response rate (ORR) in patients with undetectable PD-L1 expression or < 1%. A fixed-effect or random-effects model was adopted depending on between-study heterogeneity. Results: Four studies evaluated atezolizumab + CT (IMpower 130,131,132 and 150), three studies pembrolizumab + CT (Keynote 021, 189 and 407) and one study evaluated nivolumab + CT (CheckMate 227). The eight eligible studies included 2037 patients (1246 with PD-L1 negative and 791 with PD-L1 expression < 1%). Most of the patients were men and smokers, with a median age of 64 years. There were 1423 Non-squamous (69.8 %) and 614 Squamous tumors (30%). The combination (PD-1/PD-L1 inhibitor + CT) was significantly associated with improvement of OS (hazards ratio [HR], 0.75; 95% CI 0.63–0.89; p < 0.0001), PFS (HR, 0.72; 95% CI 0.65–0.80; p < 0.0001) and ORR (relative ratio [RR], 2.59; 95% CI 1.46–4.60; p < 0.0001). Moreover, median duration of response (DOR) was statistically longer with combination (8.1 months versus 4.9; p < 0.0008). Conclusions: For patients with untreated NSCLC with low ( < 1%) or undetectable PD-L1 expression, the anti-PD-1/PD-L1 combination with chemotherapy, compared with chemotherapy alone, is associated with significantly improved OS, PFS, and ORR.

BackgroundPrevious studies, both in vitro and in vivo, have established that apatinib has anti-tumor properties. However, insufficient empirical evidence of the efficacy and safety of apatinib has been published for bone and soft tissue sarcoma, the reported results differing widely. Here, we conducted a meta-analysis to assess the efficacy and toxicity of apatinib for the treatment of bone and soft tissue sarcoma.MethodsPubmed, Medline, Web of Science, ScienceDirect, Ovid, Embase, Cochrane Library, Scopus, Vip (China), Cnki (China), Wanfang (China), and CBM (China) databases and literature from conferences were searched for studies of apatinib for the treatment of bone and soft tissue sarcomas, published from the inception of each database to Sep 1, 2020, without language restrictions. Primary outcomes were efficacy and toxicity of apatinib for the treatment of bone and soft tissue sarcoma, including treatment response, progression-free survival (PFS), and the incidence of adverse events. After extraction of data and methodological quality evaluation, random or fixed-effects models, as appropriate, were selected to calculate pooled effect estimates using R software (Version 3.4.1).ResultsA total of 21 studies with 827 participants were included in the present meta-analysis. The mean MINORS score was 10.48 ± 1.75 (range: 7-13), indicating evidence of moderate quality. Pooled outcomes indicated that overall response rate (ORR) and disease control rate (DCR) were 23.85% (95% CI: 18.47%-30.21%) and 79.16% (95% CI: 73.78%-83.68%), respectively. Median PFS ranged from 3.5 to 13.1 months, with a mean of 7.08 ± 2.98 months. Furthermore, the rates of PFS (PFR) after 1, 6, and 12 months were 99.31%, 44.90%, and 14.31%, respectively. Drug-related toxicity appears to be common in patients administered apatinib, for which hand-foot syndrome (41.13%), hypertension (36.15%), and fatigue (20.52%) ranked the top three most common adverse events. However, the incidence of grade 3-4 adverse events was relatively low and manageable.ConclusionsBased on the best evidence currently available, apatinib demonstrates promising clinical efficacy and an acceptable safety profile for the treatment of advanced bone and soft tissue sarcoma, although additional high-quality clinical studies are required to further define its properties and toxicity.

e16536 Background: Axitinib has been used extensively as a single agent or in combination with immunotherapy in the treatment of advanced renal cell carcinoma. It can be often discontinued due to adverse events. A meta-analysis of clinical trials was performed to evaluate the overall tolerability of axitinib in this setting. Methods: PubMed (Up to November 2020) was searched to identify clinical trials of axitinib in advanced or metastatic renal cell carcinoma. Reported data was collected to include axitinib and control discontinuation due to adverse events. A random or fixed effects model was used to determine summary incidences, relative risks, and 95% confidence intervals depending on the heterogeneity of included studies. Results: A total of 11 studies including 4,056 patients (axitinib alone n = 1384, axitinib combination n = 987, control n = 1685) were included for analysis. The summary discontinuation rate for axitinib due to adverse events was 13.4% (95% CI; 11.7-15.2%) with 8.9% (95% CI: 5.3-14.6%) as a single agent and 26.6% (95% CI:17.8 –37.8%) in combination with other agents. In comparison with controls based on randomized controlled studies, axitinib overall has similar discontinuation rate due to adverse events (RR: 1.18, 95% CI: 0.77-1.80). However, there was a significantly higher discontinuation rate with axitinib in combination with other agents including immunotherapeutic agents PD-L1 inhibitors than control treatment (RR: 1.52, 95% CI: 1.24-1.86). Conclusions: The tolerability of axitinib may vary significantly with its use as a single agent or in combination in the treatment of advanced renal cell carcinoma. Further studies are needed to improve its tolerability as a part of combination therapy.

Background/Aims: Urothelial cancer (UC) as a chemotherapy-sensitive tumor, has achieved remarkable progresses in therapeutic paradigm, particularly in the advanced/metastatic stages. However, both clinicians and patients are confused when it comes to choosing the optimal chemotherapy. Hence, this article was aimed to conduct a comprehensive comparison of different chemotherapy regimens for advanced or metastatic UC in terms of survival benefits or adverse events. Methods: The online databases PubMed, EMBASE and Web of Science were searched systematically and comprehensively for randomized controlled trials (RCTs) up to September 15, 2017. The pooled hazard ratios (HRs) or odds ratios (ORs) with 95% credible interval (CrI) were calculated by Markov chain Monte Carlo methods. The effectiveness and safety of included regimens were conducted to provide a hierarchy by means of rank probabilities with the help of “R-3.4.0” software and the “gemtc-0.8.2” package. The surface under the cumulative ranking curve (SUCRA) was also incorporated in our analysis for ranking the corresponding chemotherapy regimens. Results: Ten different chemotherapy regimens involved in this article were predominantly of trials in a first-line setting, and eight clinical outcomes were ultimately analyzed in this study. In terms of Overall response rate (ORR), Overall survival (OS) or Progression-free survival (PFS)/Time to progression (TTP), the rank probabilities and SUCRA indicated that Paclitaxel/cisplatin/gemcitabine (PCG) was superior to gemcitabine/cisplatin (GC) or methotrexate/vinblastine/doxorubicin/cisplatin (MVAC), the traditional first-line treatment for advanced/metastatic UC. In the case of ORR or PFS/TTP, GC+sorafenib also displayed its superiority in comparison with GC or MVAC. Despite their survival benefits, PCG or GC+sorafenib presented a relatively higher incidence of adverse events. Conclusion: Our results revealed that by adding a paclitaxel or sorafenib into the first-line GC, it could yield a better survival benefit, but also worsen adverse events for advanced/ metastatic UC. Clinically, physicians should weigh the merits of these approaches to maximize the survival benefits of eligible patients.
