Review
BACKGROUND
Lingzhi and Yunzhi are medicinal mushrooms commonly used with cytotoxic chemotherapy in cancer patients in Asian countries. The current systematic review aims to identify potential pharmacokinetic or pharmacodynamic interactions from the existing literature to ensure their effective and safe combination usage in cancer patients.
METHODS
A systematic search was conducted on nine major Chinese and English databases, including China Journal Net, Allied and Complementary Medicine Database, and Ovid MEDLINE, etc., to identify clinical, animal, and in-vitro studies that evaluate the effect of combined use of Lingzhi or Yunzhi with cytotoxic drugs. The Jadad scale was used to assess the quality of clinical studies.
RESULTS
This search identified 213 studies, including 77 clinical studies that reported on the combined use of cytotoxic drugs with Yunzhi (n = 56) or Lingzhi (n = 21). Majority of these clinical studies demonstrated modest methodological quality. In clinical practice, the most commonly used cytotoxic drugs with Lingzhi were cisplatin, 5-fluorouracil (5-FU) and paclitaxel, whereas Tegafur/uracil (UFT)/Tegafur, 5-FU, and mitomycin were the ones used more often with Yunzhi. Only two clinical pharmacokinetic studies were available showing no significant interactions between Polysaccharide K (PSK) and Tegafur. From the pharmacodynamic interactions perspective, combination uses of Yunzhi/Lingzhi with cytotoxic drugs in clinical practice could lead to improvement in survival (n = 31) and quality of life (n = 17), reduction in tumor lesions (n = 22), immune modulation (n = 38), and alleviation of chemotherapy-related side effects (n = 14) with no reported adverse effects.
CONCLUSION
Our findings suggest that the clinical combination use of Lingzhi or Yunzhi with cytotoxic drugs could enhance the efficacy and ameliorate the adverse effects of cytotoxic drugs, leading to improved quality of life in cancer patients. More high quality clinical studies including pharmacokinetic herb-drug interactions studies are warranted to verify these observations and mechanisms involved. Based on the high quality clinical data, pharmacoepidemiology methods and bioinformatics or data mining could be adopt for further identification of clinical meaningful herb-drug interactions in cancer therapies.

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
Systematic review and network meta-analysis comparing palbociclib with chemotherapy agents for the treatment of postmenopausal women with HR-positive and HER2-negative advanced/metastatic breast cancer.
PURPOSE
To compare palbociclib + letrozole and palbociclib + fulvestrant with chemotherapy agents in postmenopausal women with hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) advanced/metastatic breast cancer (ABC/MBC) who had no prior systemic treatment for advanced disease (first line) or whose disease progressed after prior endocrine therapy or chemotherapy (second line).
METHODS
A systematic search identified randomized controlled trials (RCTs) published from January 2000 to January 2016 that compared endocrine-based therapies, chemotherapy agents, and/or chemotherapy agents + biological therapies in the first- and second-line treatment of postmenopausal women with HR+/HER2- ABC/MBC. The main outcome of interest was progression-free survival (PFS)/time to progression (TTP). Bayesian network meta-analyses (NMAs) and pairwise meta-analyses were conducted. Heterogeneity and inconsistency were assessed.
RESULTS
Sixty RCTs met eligibility criteria and were stratified by line of therapy. In the first line, palbociclib + letrozole showed statistically significant improvements in PFS/TTP versus capecitabine [intermittent: HR 0.28 (95% CrI 0.11-0.72)] and mitoxantrone [HR 0.28 (0.13-0.61)], and trended toward improvements versus paclitaxel [HR 0.59 (0.19-1.96)], docetaxel [HR 0.51 (0.14-2.03)] and other monotherapy or combination agents (HRs ranging from 0.24 to 0.99). In the second line, palbociclib + fulvestrant showed statistically significant improvements in PFS/TTP versus capecitabine [intermittent: HR 0.28 (0.13-0.65)], mitoxantrone [HR 0.26 (0.12-0.53)], and pegylated liposomal doxorubicin [HR 0.19 (0.07-0.50)], and trended toward improvements versus paclitaxel [HR 0.48 (0.16-1.44)], docetaxel [HR 0.71 (0.24-2.13)] and other monotherapy or combination agents (HRs ranging from 0.23-0.89). NMA findings aligned with direct evidence and were robust to sensitivity analyses.
CONCLUSIONS
Palbociclib + letrozole and palbociclib + fulvestrant demonstrate trends in incremental efficacy compared with chemotherapy agents for the first- and second-line treatment of HR +/HER2- ABC/MBC.

BACKGROUND AND OBJECTIVES
EUS-guided ethanol ablation has emerged as an alternative method for pancreatic lesions. Recently, paclitaxel was added to ethanol to assess ablative effects in pancreatic lesions. We performed a systematic review and meta-analysis on EUS-guided ethanol ablation (EUS E) versus EUS-guided ethanol with paclitaxel (EUS EP) ablation for the management of pancreatic lesions.
METHODS
Comprehensive search of multiple electronic databases and conference proceedings including PubMed, EMBASE, Google Scholar, and Web of Science databases (from inception to May 2020). The primary outcome evaluated complete ablation of the lesions radiologically and the secondary outcome evaluated adverse events (AEs).
RESULTS
Fifteen studies on 524 patients were included in our analysis. The pooled complete ablation rate was 58.89% (95% confidence interval (CI) = 38.72-77.80, I = 91.76%) and 55.99% (95% CI = 44.66-67.05, I = 0) in the EUS E and EUS EP groups (P = 0.796), respectively. The pooled AE rates were 13.92% (95% CI = 4.71-26.01, I = 83.43%) and 31.62% (95% CI = 3.36-68.95, I = 87.9%) in the EUS E and EUS EP groups (P = 0.299), respectively. The most common AE was abdominal pain at 7.27% (95% CI = 1.97-14.6, I = 68.2%) and 12.44% (95% CI = 0.00-39.24, I = 81.1%) in the EUS E and EUS EP groups (P = 0.583), respectively. Correlation coefficient (r) was ‒0.719 (P = 0.008) between complete ablation and lesion size.
CONCLUSION
Complete ablation rates were comparable among both groups. AE rates were higher in the EUS EP group. Further randomized controlled trials are needed to validate our findings.

Meta-Analysis
Mortality Rates After Paclitaxel-Coated Device Use in Patients With Occlusive Femoropopliteal Disease: An Updated Systematic Review and Meta-Analysis of Randomized Controlled Trials.
PURPOSE
A late increased mortality risk has been reported in a summary level meta-analysis of patients with femoropopliteal artery occlusive disease treated with paclitaxel-coated angioplasty balloons and stents. However, at the longer follow up timepoints that analysis was limited by small trial numbers and few participants. The aim of this study was to report an updated summary level risk of all-cause mortality after treatment with paclitaxel-coated devices in that same patient group.
MATERIALS AND METHODS
We performed a systematic review and meta-analysis of randomized controlled trials to investigate the mortality outcomes associated with paclitaxel-coated devices used to treat patients with occlusive disease of femoropopliteal arteries (last search date December 10, 2020). The single primary endpoint was all-cause mortality.
RESULTS
We identified 34 randomized controlled trials (7654 patients; 84% intermittent claudication). There were 622 deaths among 4147 (15.0%) subjects in the paclitaxel device group and 475 deaths among 3507 (13.5%) subjects in the noncoated control group [relative risk ratio (RR) 1.07, 95% confidence interval (CI) 0.96 to 1.20, p=0.20, I=0%). All-cause mortality was similar between groups at 12 months (34 studies, 7654 patients; RR 0.99, 95% CI 0.81 to 1.22, p=0.94, I=0%), 24 months (20 studies, 3799 patients; RR 1.16, 95% CI 0.87 to 1.55, p=0.31, I=0%), and 60 months (9 studies, 2288 patients; RR 1.19, 95% CI 0.98 to 1.45, p=0.08, I=0%).
CONCLUSION
This updated meta-analysis with included additional trials and larger patient numbers shows no evidence of increased risk of all-cause mortality in patients treated with paclitaxel-coated devices, compared with uncoated devices for femoropopliteal disease at all time points to 60 months. There is therefore no justification to limit their use, or alter regulatory body follow-up recommendations 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.

Review
OBJECTIVE
Indications for endovascular treatment of femoropopliteal (FP) lesions have steadily increased over the past decade. Accordingly, the number of devices has also increased but the choice of the best endovascular treatment remains to be defined. The aim of this meta-analysis was to summarize all studies investigating endovascular treatment of FP lesions greater than 150 mm from 2010 to 2021.
METHODS
Articles were searched using PubMed, Scopus, and Cochrane. Included studies were randomized controlled trials (RCTs), cohort studies, and case series (prospective and retrospective) that evaluated any endovascular procedure in patients with long FP lesions classified TASC (Trans-Atlantic Inter-Society Consensus document II on management of peripheral arterial disease) C and/or D, and a mean length 150 mm, primary outcome had to be the 1-year primary patency. Overall estimate of primary patency, secondary patency, and freedom from target lesion revascularization (TLR) at 1 year depending on the different devices were investigated. The meta-analysis was conducted following the requirements of the MOOSE (Meta-analysis of Observational Studies in Epidemiology) checklist.
RESULTS
Forty-four papers comprising 4847 patients and 5282 treated limbs were included. Mean lesions length ranged from 150.5 to 330 mm. The pooled 1-year primary and secondary patencies, and freedom from TLR rates were 0.71 (95% CI: 0.67-0.74), 0.87 (95% CI: 0.83-0.91), and 0.79 (95% CI: 0.74-0.84), respectively. Primary permeability at 1 year were 0.68 (95% CI: 0.62-0.73), 0.67 (95% CI: 0.60-0.74), 0.74 (95% CI: 0.64-0.84), and 0.83 (95% CI: 0.78-0.88) for bare metal stents, covered stents (CSs), drug-eluting stents, and drug-coated balloons (DCBs), respectively. Lesions treated with DCB had the highest 1-year primary patency rate.
CONCLUSIONS
At 1-year, endovascular procedures for FP lesions greater than 150 mm obtain satisfactory results. High primary patency rates were obtained with drug-coated devices, while CSs obtained less favorable results. Randomized studies comparing different devices in the treatment of long FP lesions remain necessary to determine the most optimal approach for the management of these patients.
CLINICAL IMPACT
This paper highlights on the one hand the satisfactory results of endovascular treatment on complex femoropopliteal lesions formerly reserved for conventional surgery. On the other hand, among the available devices, paclitaxel-eluting devices seem to show superior results which should make them recommended as first-line treatment.

Editor's Choice - Paclitaxel Coated Balloon Angioplasty vs. Plain Balloon Angioplasty for Haemodialysis Arteriovenous Access Stenosis: A Systematic Review and a Time to Event Meta-Analysis of Randomised Controlled Trials.
OBJECTIVE
A systematic review and meta-analysis of randomised controlled trials (RCTs) was performed to determine the effectiveness and safety of drug coated balloon (DCB) angioplasty compared with uncoated plain balloon (PB) angioplasty in treating arteriovenous access stenosis.
METHODS
MEDLINE, Embase, Scopus, and the Cochrane Central Register of Controlled Trials were searched for RCTs comparing paclitaxel coated DCB and PB angioplasty for arteriovenous access stenosis. The last date of the literature search was 31 December 2020. Risk of bias of the retrieved studies was assessed with the Cochrane Collaboration tool for assessing risk of bias (RoB 2.0). The random effects model was used to estimate the risk of loss of target lesion patency (six and 12 months) and circuit patency (six and 12 months). Procedure related adverse events and mortality rate were also compared. Patency results were pooled using the time to event meta-analytical method and the quality of evidence was assessed according to the GRADE approach.
RESULTS
Sixteen eligible trials, including 1 682 lesions, were included in the quantitative analysis for the efficacy and safety of paclitaxel coated DCBs. DCBs were associated with a lower risk of loss of target lesion patency at six months (HR 0.53, 95% CI 0.42 - 0.66) and 12 months (HR 0.60, 95% CI 0.47 - 0.76), and were also associated with improved six and 12 month circuit patency. Overall quality of evidence was moderate to low. Procedural complications were rare, and the risk of death up to 12 months was similar between the two groups (OR 1.03, 95% CI 0.68 - 1.56).
CONCLUSION
Paclitaxel coated DCBs reduced the risk of loss of target lesion patency and circuit patency in arteriovenous access stenosis compared with PBs. Considering the heterogeneity of the included trials, there is a need to investigate optimal treatment regimens regarding drug dose and agent of the DCB and the treatment procedure.

Meta-Analysis
Taxane-based chemotherapy regimens are used as first-line treatment for breast cancer. Neurotoxicity, mainly taxane-induced peripheral neuropathy (TIPN), remains the most important dose-limiting adverse event. Multiple genes may be associated with TIPN; however, the strength and direction of the association remain unclear. For this reason, we systematically reviewed observational studies of TIPN pharmacogenetic markers in breast cancer treatment. We conducted a systematic search of terms alluding to breast cancer, genetic markers, taxanes, and neurotoxicity in Ovid, ProQuest, PubMed, Scopus, Virtual Health, and Web of Science. We assessed the quality of evidence and bias profile. We extracted relevant variables and effect measures. Whenever possible, we performed random-effects gene meta-analyses and examined interstudy heterogeneity with meta-regression models and subgroup analyses. This study follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and STrengthening the REporting of Genetic Association Studies (STREGA) reporting guidance. A total of 42 studies with 19,431 participants were included. These evaluated 262 single-nucleotide polymorphisms (SNPs) across 121 genes. We conducted meta-analyses on 23 genes with 60 SNPs (19 studies and 6246 participants). Thirteen individual SNPs (ABCB1-rs2032582, ABCB1-rs3213619, BCL6/-rs1903216, /CAND1-rs17781082, CYP1B1-rs1056836, CYP2C8-rs10509681, CYP2C8-rs11572080, EPHA5-rs7349683, EPHA6-rs301927, FZD3-rs7001034, GSTP1-rs1138272, TUBB2A-rs9501929, and XKR4-rs4737264) and the overall SNPs' effect in four genes (CYP3A4, EphA5, GSTP1, and SLCO1B1) were statistically significantly associated with TIPN through meta-analysis. In conclusion, through systematic review and meta-analysis, we found that polymorphisms, and particularly 13 SNPs, are associated with TIPN, suggesting that genetics does play a role in interindividual predisposition. Further studies could potentially use these findings to develop individual risk profiles and guide decision making.

Review
Pancreatic cancer is a malignant tumor with one of the worst prognosis. Its incidence has been on the rise in recent years. First-line and second-line treatments as well as adjuvant therapies have been employed in clinical trials for pancreatic cancer along with traditional chemotherapy and radiotherapy that has been enhanced. The prognosis of pancreatic ductal adenocarcinoma (PDAC) is still quite bad despite recent improvements in diagnostic and treatment methods. Since most patients are not candidates for treatment with a curative purpose, effective palliative care is crucial. For this systematic review, between December 25, 2022, and January 5, 2023, we searched PubMed, Medline, Cochrane, and Science Direct and discovered 225 relevant articles. The appropriateness of the literature abstracts for the pooled analysis was evaluated using different combinations of keywords such as pancreatic cancer, first- and second-line chemotherapy, palliative chemotherapy, gemcitabine and nab-paclitaxel (GnP), FOLFIRINOX (FFX), and fluorouracil. Eight research studies with a total of 15,236 people, including systematic reviews, meta-analyses, and randomized controlled trials (RCTs), were included. The only treatment of choice for patients without metastatic disease who have clinical staging that suggests resectable or borderline resectable pancreatic cancer (BRPC) should be resection. This research examined how first- and second-line chemotherapeutic regimens (using different drug combinations) affected patients with locally advanced pancreatic cancer (LAPC) or BRPC and how they responded in terms of overall survival (OS), tumor resectability, and progression-free interval. The review concludes by highlighting the results of these therapies. Notably, a growing body of research indicates that the two most popular first-line medication combinations GnP and FFX have similar results in RCTs and in real-world populations. Results of second-line therapy after first-line regime failure are still dismal, and there is still a great deal of doubt regarding the best course of action. More RCTs and real-world evidence studies that address current and innovative regimens, as well as the best order in which to administer them, are required, with a greater emphasis on targeted therapy with fewer side effects.
