Meta-Analysis
Neoadjuvant immunotherapy and chemotherapy regimens for the treatment of high-risk, early-stage triple-negative breast cancer: a systematic review and network meta-analysis.
BACKGROUND
Patients with triple-negative breast cancer (TNBC) are generally younger and more likely to experience disease recurrence and have the shortest survival among all breast cancer patients. Recently, neoadjuvant delivery of the programmed cell death protein-1 inhibitor pembrolizumab plus chemotherapy followed by adjuvant pembrolizumab was approved for patients with high-risk, early-stage TNBC, but this treatment regimen has not been evaluated in head-to-head trials with other neoadjuvant treatment regimens. Therefore, the objective of this study was to estimate the relative efficacy of neoadjuvant pembrolizumab + chemotherapy followed by adjuvant pembrolizumab versus other neoadjuvant treatments for early-stage TNBC through a systematic review and network meta-analysis (NMA).
METHODS
EMBASE, MEDLINE, Cochrane Central Register of Controlled Trials, conference abstracts, and clinical trial registries were searched for randomized controlled trials evaluating neoadjuvant treatments for early-stage TNBC. NMA was performed to estimate relative treatment effects among evaluated interventions.
RESULTS
Five trials met the inclusion criteria and were included in the NMA. The relative efficacy of neoadjuvant pembrolizumab + chemotherapy followed by adjuvant pembrolizumab was favorable to paclitaxel followed by anthracycline + cyclophosphamide in terms of pathologic complete response (pCR), event-free survival (EFS), and overall survival; paclitaxel + carboplatin followed by anthracycline + cyclophosphamide in terms of pCR and EFS; paclitaxel + bevacizumab followed by anthracycline + cyclophosphamide + bevacizumab in terms of pCR; and paclitaxel + carboplatin + veliparib followed by anthracycline + cyclophosphamide in terms of EFS.
CONCLUSIONS
Neoadjuvant pembrolizumab + chemotherapy followed by adjuvant pembrolizumab confers benefits in response and survival outcomes versus alternative neoadjuvant treatments for early-stage TNBC.

Nanoparticle Albumin‑Bound Paclitaxel and Solvent-Based Paclitaxel as Chemotherapy Options for Patients With Advanced Gastric Cancer: A Systematic Review and Meta-Analysis.
The aim of this study is to assess and compare the effectiveness and safety of nanoparticle albumin-bound paclitaxel (nab-PTX) and solvent-based PTX (sb-PTX) as treatment options for advanced gastric cancer. This meta-analysis was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. We carried out a comprehensive search of PubMed, Google Scholar, and EMBASE from inception to June 15, 2023. The search strategy included the following keywords: "Nanoparticle albumin-bound paclitaxel," "solvent-based paclitaxel," and "advanced gastric cancer," along with their synonyms and medical subject heading (MeSH) terms. In this meta-analysis, the primary outcome was the comparison of overall survival and progression-free survival between the two groups. For safety purposes, we compared the risk of hematological and non-hematological events between the two groups. Four studies were included in this meta-analysis enrolling 1052 patients (483 received nb-PTX and 569 received sb-PTX). In terms of efficacy, nab-PTX showed favorable trends in overall survival and progression-free survival, despite no statistically significant differences being reported. The subgroup meta-analysis showed that nab-PTX seemed to have a better effect on peritoneal metastasis compared to sb-PTX. Regarding safety, the number of patients with neutropenia and leucopenia was significantly higher in the nab-PTX group compared to the sb-PTX group. However, the difference was statistically insignificant. Future research should focus on conducting more robust studies to further validate these findings and establish a stronger evidence base for the use of nab-PTX in this patient population.

PURPOSE
This meta-analysis was exerted in assessing the anticancer efficacy and safety of nab-paclitaxel (nab-P) when combined with platinum compound agents for therapy in patients with non-small cell lung cancer (NSCLC).
METHOD
We systematically searched the following seven electronic databases: PubMed, Cochrane Library, Web of Science, Embase, CNKI, Wan Fang, and China Science and Technology Journal Data. Randomized comparative clinical [randomized controlled clinical trial (RCT)] studies on nab-P plus platinum and carboplatin or cisplatin in combination with conventional chemotherapy agents or traditional paclitaxel were searched.
RESULTS
A total of 19 RCT studies involving 6,011 patients were analyzed. The primary outcome includes the overall response rate (ORR), overall survival (OS), and progression-free survival (PFS). The secondary outcome includes adverse events (AEs). Nab-P combined with platinum (carboplatin/cisplatin) had a better ORR [odds ratio (OR) = 1.66, 95% confidence interval (CI) (1.34, 2.05), < 0.001] and improved PFS [hazard ratio (HR) = 0.84, 95% CI: (0.74, 0.94), = 0.01] and OS [HR = 0.86, 95% CI: (0.78, 0.96), = 0.008] in NSCLC patients. ORR [OR = 2.18, 95% CI: (1.07, 4.43)], PFS [HR = 0.62, 95% CI: (0.40, 0.97)], and OS [HR = 0.63, 95% CI: (0.49, 0.81)] were significantly improved among patients aged >70 years, and ORR [OR = 1.80, 95% CI: (1.20, 2.70)] and PFS [HR = 0.74, 95% CI: (0.56, 0.97)] were significantly elevated with SCC rate ≥65% in NSCLC patients (all > 0.05). Among the adverse effects, the prevalence of neutropenia, neuralgia, and arthralgia/myalgia (≥ grade 3) compared to that of the control group. On the other hand, the prevalence of anemia and thrombocytopenia was higher in the nab-P plus platinum (carboplatin/cisplatin) compared to that of controls. It is worth noting that fatigue did not show statistical significance.
CONCLUSION
Nab-P in combination with carboplatin/cisplatin regimen improves efficacy and tolerability in patients with NSCLC.

Efficacy and safety of bevacizumab in patients with malignant melanoma: a systematic review and PRISMA-compliant meta-analysis of randomized controlled trials and non-comparative clinical studies.
Malignant melanoma is a highly aggressive cancer that spreads and metastasizes quickly. In recent years, the antiangiogenic drug bevacizumab has been trialed to treat malignant melanoma. We conducted the first meta-analysis to examine the efficacy and safety of bevacizumab combined with other drugs in malignant melanoma. We searched for randomized controlled trials (RCTs) and non-comparative clinical studies of bevacizumab combined with chemotherapy, targeted medicine, and interferon to treat malignant melanoma in PubMed, Embase, the Cochrane Library, and Web of Science. Meta-analysis of RCT was performed using Review Manager (version 5.4), and non-comparative meta-analysis was performed using R (version 4.0.3). The primary outcome was the objective response rate. Depending on the heterogeneity of the included studies, the pooled outcomes and 95% CI were calculated using either random-effects or fixed-effect models. Subgroup outcomes were calculated with possible relevant variables. Sensitivity analyses were carried out by excluding each study from the highly heterogeneous pooled results in turn. Funnel plot and Begg's test were used to test the included studies' potential publication bias. The level of significance was set at < 0.05. This meta-analysis included 20 trials: five RCTs and 15 non-comparative clinical studies with a total of 23 bevacizumab intervention arms. In 14 treatment arms, bevacizumab was combined with chemotherapy drugs such as fotemustine, dacarbazine, carboplatin/paclitaxel, and temozolomide. In six treatment arms, bevacizumab was combined with targeted medicines such as imatinib, everolimus, sorafenib, erlotinib, and temsirolimus. There were also six treatment arms that used bevacizumab in combination with interferon. The pooled objective response rate was 15.8% (95% CI, 11.4%-20.2%). Bevacizumab plus carboplatin/paclitaxel significantly increased the overall survival compared to carboplatin/paclitaxel (HR = 0.64, 95% CI, 0.49-0.85, < 0.01). Fatigue, nausea, leukopenia, thrombocytopenia, and neutropenia were the most common adverse events. The pooled incidence of hypertension of all bevacizumab arms in malignant melanoma was 32.4% (95% CI, 24.5%-40.3%). This study showed that bevacizumab combined with chemotherapy might be effective and well-tolerated in patients with stage III or IV unresectable malignant melanoma. : [https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=304625], identifier [CRD42022304625].

Meta-Analysis Review
OBJECTIVE
The combination of nanoparticle albumin-bound paclitaxel (nab-PTX)/paclitaxel (PTX) with immune checkpoint inhibitors (ICIs) has demonstrated significant efficacy in cancer patients. However, the safety of these combination regimens remains conflicting in former researches. Therefore, in order to address this issue, we performed a systematic review and network meta-analysis (NMA) to evaluate and compare the safety profile.
METHODS
We performed a systematic review by searching randomized controlled trials (RCTs) from PubMed, EMBASE, Cochrane Library, ClinicalTrials.gov, and Web of Science up to August 15, 2022. The primary outcomes were all-grade (grade 1-5) and high-grade (grade 3-5) immune-related adverse events (irAEs). Secondary outcomes were all-grade (grade 1-5) and high-grade (grade 3-5) irAEs of subgroups of ICIs.
RESULTS
There were 22 RCTs included in the NMA, involving a total of 15 963 patients diagnosed with any type of cancer. ICIs+nab-PTX was associated with a noticeably decreased risk of grade 3-5 pneumonitis (odds ratio [OR]=0.28, 95% credible interval [CrI]: 0.09,0.90) compared to ICI monotherapy; ICIs+PTX showed a lower risk of grade 1-5 hyperthyroidism (OR=0.46, 95% CrI: 0.22-0.96) and grade 1-5 hypothyroidism (OR=0.49, 95% CrI: 0.26-0.93) than ICIs. Compared with PD-1, PD-1+PTX was associated with a statistically significantly lower risk of grade 1-5 pneumonitis (OR=0.32, 95% CrI: 0.11-0.92). PD-L1 resulted in a noticeably lower risk of grade 1-5 hypothyroidism (OR=0.34, 95% CrI: 0.12-1.00) than PD-L1+PTX. Nearly all treatment regimens containing ICIs demonstrated significantly higher risks of irAEs compared to the standard chemotherapy groups.
CONCLUSION
Nab-PTX/PTX+ICIs demonstrated an approach leading to decreased risk of irAEs compared with ICI monotherapy. This finding supports that ICIs+nab-PTX/PTX may be a safer treatment strategy. Moreover, we also found that the combination regimens containing ICIs had a higher risk of irAEs than standard chemotherapy. Additionally, ICIs+nab-PTX demonstrated a decreased risk of irAEs compared to ICIs+PTX. PD-1 inhibitors were associated with a higher risk of irAEs than PD-L1 inhibitors.

Taxane-induced peripheral neuropathy (TIPN) is an important cause of premature treatment cessation and dose-limitation in cancer therapy. It also reduces quality of life and survivorship in affected patients. Genetic polymorphisms in the CYP3A family have been investigated but the findings have been inconsistent and contradictory. A systematic review identified 12 pharmacogenetic studies investigating genetic variation in and and TIPN. In our candidate gene study, 288 eligible participants (211 taxane participants receiving docetaxel or paclitaxel, and 77 control participants receiving oxaliplatin) were successfully genotyped for and . Genotyping data was transformed into a combined CYP3A metaboliser phenotype: Poor metabolisers, intermediate metabolisers and extensive metabolisers. Individual genotypes and combined CYP3A metaboliser phenotypes were assessed in relation to neurotoxicity, including by meta-analysis where possible. In the systematic review, no significant association was found between and TIPN in seven studies, with one study reporting a protective association. For , one study has reported an association with TIPN, while four other studies failed to show an association. Evaluation of our patient cohort showed that paclitaxel was found to be more neurotoxic than docetaxel ( < 0.001). Diabetes was also significantly associated with the development of TIPN. The candidate gene analysis showed no significant association between either SNP () and the development of TIPN overall, or severe TIPN. Meta-analysis showed no association between these two variants and TIPN. Transformed into combined CYP3A metaboliser phenotypes, 30 taxane recipients were poor metabolisers, 159 were intermediate metabolisers, and 22 were extensive metabolisers. No significant association was observed between metaboliser status and case-control status. We have shown that the risk of peripheral neuropathy during taxane chemotherapy is greater in patients who have diabetes. CYP3A genotype or phenotype was not identified as a risk factor in either the candidate gene analysis or the systematic review/meta-analysis, although we cannot exclude the possibility of a minor contribution, which would require a larger sample size.

Meta-Analysis Review
Dose-dense regimen versus conventional three-weekly paclitaxel combination with carboplatin chemotherapy in first-line ovarian cancer treatment: a systematic review and meta-analysis.
BACKGROUND
Paclitaxel dose-dense regimen has been controversial in clinical trials in recent years. This systematic review and meta-analysis tried to evaluate the efficacy and safety of paclitaxel dose-dense chemotherapy in primary epithelial ovarian cancer.
METHODS
An electronic search following PRISMA guidelines was conducted (Prospero registration number: CRD42020187622), and then a systematic review and meta-analysis of included literature were initiated to determine which regimen was better.
RESULTS
Four randomized controlled trials were included in the qualitative evaluation, and 3699 ovarian cancer patients were included in the meta-analysis. The meta-analysis revealed that the dose-dense regimen could prolong PFS (HR0.88, 95%CI 0.81-0.96; p = 0.002) and OS (HR0.90, 95%CI 0.81-1.02; p = 0.09), but it also increased the overall toxicity (OR = 1.102, 95%CI 0.864-1.405; p = 0.433), especially toxicity of anemia (OR = 1.924, 95%CI 1.548-2.391; p < 0.001), neutropenia (OR = 2.372, 95%CI 1.674-3.361; p < 0.001). Subgroup analysis indicated that the dose-dense regimen could significantly prolong not only PFS (HR0.76, 95%CI 0.63-0.92; p = 0.005 VS HR0.91, 95%CI 0.83-1.00; p = 0.046) but also OS (HR0.75, 95%CI 0.557-0.98; p = 0.037 VS HR0.94, 95%CI 0.83-1.07; p = 0.371) in Asian, and overall toxicity was significantly increased in Asians (OR = 1.28, 95%CI: 0.877-1.858, p = 0.202) compared to non-Asians (OR = 1.02, 95%CI 0.737-1.396, p = 0.929).
CONCLUSION
Paclitaxel dose-dense regimen could prolong PFS and OS, but it also increased the overall toxicity. Therapeutic benefits and toxicity of dose-dense are more obvious in Asians compared to non-Asians, which need to be further confirmed in clinical trials.

Meta-Analysis Review
Drug-coated balloons (DCBs) have been used in dialysis patients with arteriovenous fistula (AVF) stenosis, but whether DCBs have advantages over ordinary balloons is still controversial. A meta-analysis was designed to investigate the safety and efficacy of DCBs and common balloons (CBs) in the treatment of AVF stenosis. We searched the PubMed, EMBASE, and China National Knowledge Internet (CNKI) databases for randomized controlled trials that evaluated the comparison of DCB angioplasty versus CB angioplasty for AVF stenosis in dialysis patients and reported at least one outcome of interest. The results showed that the DCB group had a higher first-stage patency rate of the target lesion 6 months [odds ratio, OR = 2.31, 95% confidence interval, CI: (1.69, 3.15), p < .01] and 12 months [OR = 2.09, 95% CI: (1.50, 2.91), p < .01] after surgery. There was no statistically significant difference in all-cause mortality between the two groups at 6 months [OR = 0.85, 95% CI: (0.47, 1.52), p = .58] and 12 months [OR = 0.99, 95% CI: (0.60, 1.64), p = .97]. Compared with CB, DCBs as a new endovascular treatment for AVF stenosis have a higher primary patency rate of target lesions and can delay the occurrence of restenosis. There is no evidence that DCB can increase the mortality of patients.

Review
BACKGROUND AND AIMS
Several widely used medications, with a relevant efficacy profile, are toxic to the peripheral nervous system and an even larger number of agents are suspected to be neurotoxic. There are concerns about the use of these drugs in patients with Charcot-Marie-Tooth disease (CMT), a hereditary motor and sensory neuropathy. This review provides evidence-based updated recommendations on this clinically relevant topic.
METHODS
A systematic review of the available studies/reports written in English was performed from July to September 2022 including in the search string all reported putative neurotoxic drugs.
RESULTS
The results of our systematic review provide evidence-based support for the statement that use of vincristine, and possibly paclitaxel, can occasionally induce an atypical, and more severe, course of drug-related peripheral neurotoxicity in CMT patients. It is therefore reasonable to recommend caution in the use of these compounds in CMT patients. However, no convincing evidence for a similar recommendation could be found for all other drugs.
INTERPRETATION
It is important that patients with CMT are not denied effective treatments that may prolong life expectancy for cancer or improve their health status if affected by non-oncological diseases. Accurate monitoring of peripheral nerve function in CMT patients treated with any neurotoxic agent remains mandatory to detect the earliest signs of neuropathy worsening and atypical clinical courses. Neurologists monitoring CMT patients as part of their normal care package or for natural history studies should keep detailed records of exposures to neurotoxic medications and support reporting of accelerated neuropathy progression if observed.

Review
OBJECTIVE
Local Liquid drug (LLD) delivery devices have recently emerged as a novel approach to treat peripheral arterial disease. This systemic review aims to identify and evaluate the clinical utility of the most commonly used delivery devices.
METHODS
A systemic review was performed using the Medical Subjects Heading terms of "drug delivery," "liquid," "local," and "cardiovascular disease" in PubMed, Google Scholar, and Scopus.
RESULTS
Four commonly used delivery devices were identified, including (1) the Bullfrog Micro-Infusion Device, (2) the ClearWay RX Catheter, (3) the Occlusion Perfusion Catheter, and (4) the Targeted Adjustable Pharmaceutical Administration. All have shown to successfully deliver liquid therapeutic into the target lesion and have exhibited favorable safety and efficacy profiles in preclinical and clinical trials. The LLD devices have the ability to treat very long or multiple lesions with a single device, providing a more economical option. The safety profile in LLD clinical studies is also favorable in view of recent concerns regarding adverse events with crystalline-paclitaxel-coated devices.
CONCLUSION
There is clear clinical evidence to support the concept of local liquid delivery to treat occlusive arterial disease.
CLINICAL IMPACT
The 'leave nothing behind' strategy has been at the forefront of the most recent innovations in the field of interventional cardiology and vascular interventions. Although drug coated balloons have overcome limitations associated with plain old balloon angioplasty and peripheral stents, recent safety concerns and cost considerations have impacted their usage. In this review, various liquid drug delivery devices are presented, showcasing their capabilities and success in both preclinical and clinical settings. These innovative liquid delivery devices, capable of targeted delivery and their ability to be re-used for multiple treatment sites, may provide solutions for current unmet clinical needs.
