Meta-Analysis Review
BACKGROUND
The value of nanoparticle albumin-bound paclitaxel (nab-paclitaxel) in neoadjuvant systemic therapy for breast cancer remains uncertain.
METHODS
Both electronic databases and proceedings of oncologic meetings were included in systematic literature search. Pooled rates of pathological complete response (pCR), odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using fixed-effect or random-effect model to determine the effect of neoadjuvant nab-paclitaxel.
RESULTS
Twenty-one studies with 2357 patients were included, 3 of which were randomized clinical trials. The aggregate pCR(ypT0/is ypN0) rate was 32% (95% CI 25-38%) in unselected breast cancer patients and variated in different subtypes. Within randomized clinical trials, the probability of achieving pCR was significantly higher in the nab-paclitaxel group than in the conventional taxanes group (OR = 1.383, 95%CI 1.141-1.676, p = 0.001). For non-hematological toxic effect, any grade and grade 3-4 peripheral sensory neuropathy occurred more frequently with nab-paclitaxel compared to paclitaxel (any grade, OR = 2.090, 95%CI 1.016-4.302, p = 0.045; grade3-4, OR = 3.766, 95%CI 2.324-6.100, p < 0.001). Hypersensitivity was more common with paclitaxel than nab-paclitaxel at any grade and grade 3-4.
CONCLUSION
nab-paclitaxel is an effective cytotoxic drug in neoadjuvant treatment of breast cancer, especially for aggressive tumors in terms of pCR. Exchange of nab-paclitaxel for conventional taxanes could significantly improve pCR rate with reasonable toxicities.

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.

Cardiovascular Outcomes after Paclitaxel-Coated Balloon Angioplasty versus Drug-Eluting Stent Placement for Acute Coronary Syndrome: A Systematic Review and Meta-Analysis.
: We conducted a systematic review and meta-analysis to examine the feasibility of paclitaxel-coated balloon (PCB) angioplasty for de novo lesions in patients with acute coronary syndrome (ACS) by comparing with drug-eluting stent (DES) placement. : By a systematic literature search, nine (five randomized controlled, two retrospective propensity-score matched, and two retrospective baseline-balanced) studies comparing the midterm clinical and angiographic outcomes after PCB angioplasty and DES placement were included, yielding 974 and 1130 ACS cases in PCB and DES groups, respectively. Major adverse cardiac event (MACE) was defined as a composite of cardiac mortality (CM), all-cause mortality (ACM), myocardial infarction (MI), target vessel revascularization (TVR), and target lesion revascularization (TLR). Late luminal loss (LLL) and bleeding events (BLD) were also estimated. : The frequencies of MACE in PCB and DES groups were 8.42% and 10.62%, respectively. PCB angioplasty had no significant impacts on all of MACE (risk ratio: 0.90, 95%CI: 0.68-1.18, = 0.44), CM, ACM, MI, TVR, TLR, BLD, and LLL, compared to DES placement in random-effects model. : The present systematic review and meta-analysis showed the feasibility of PCB angioplasty for the de novo lesions in patients with ACS in comparison with DES placement by the emergent procedures.

Meta-Analysis Review
Systematic Review and Network Meta-Analysis of Bevacizumab Plus First-Line Topotecan-Paclitaxel or Cisplatin-Paclitaxel Versus Non-Bevacizumab-Containing Therapies in Persistent, Recurrent, or Metastatic Cervical Cancer.
OBJECTIVE
Despite advances in cervical cancer prevention and diagnosis, outcomes for patients given a diagnosis of advanced and recurrent disease are poor. In the GOG240 trial, the addition of bevacizumab to paclitaxel-topotecan or paclitaxel-cisplatin has been shown to prolong survival compared with paclitaxel-topotecan or paclitaxel-cisplatin in patients with persistent, recurrent, or metastatic disease. However, standards of care vary between regions and countries. The purpose of this systematic review and network meta-analysis was to enable a comparison between bevacizumab + chemotherapy with multiple monotherapy or combination chemotherapy regimens in the treatment for women with advanced, recurrent, or persistent cervical cancer.
METHODS/MATERIALS
A systematic literature review was conducted to identify randomized or nonrandomized controlled trials of patients with recurrent, persistent, or metastatic cervical cancer published in English from 1999 to 2015. A feasibility study was performed to assess the heterogeneity of the trials, and a network meta-analysis was conducted. Fixed- and random-effects models were fitted to calculate the hazard ratio for overall survival (OS) for all pairwise comparisons and ranking of all interventions.
RESULTS
Twenty-three studies (19 trials) met inclusion criteria and were included in the review. Sample sizes ranged from 69 to 452, and median patient age ranged from 45 to 53 years. There was a trend toward prolonged OS with cisplatin-paclitaxel-bevacizumab and topotecan-paclitaxel-bevacizumab compared with all non-bevacizumab-containing therapies. Cisplatin-paclitaxel-bevacizumab had the highest probability of being the most efficacious compared with all regimens (68.1%), and cisplatin monotherapy had the lowest (0%).
CONCLUSIONS
The results of this network meta-analysis show that bevacizumab in combination with paclitaxel-topotecan or paclitaxel-cisplatin is likely to prolong OS over other non-bevacizumab-containing chemotherapies (eg, paclitaxel-carboplatin), which were not included in the GOG240 trial. In patients with advanced, persistent, and recurrent cervical cancer, cisplatin-paclitaxel-bevacizumab and topotecan-paclitaxel-bevacizumab showed the highest efficacy in all regimens investigated in this analysis.

Review
Comparative Effectiveness of Gemcitabine plus Nab-Paclitaxel and FOLFIRINOX in the First-Line Setting of Metastatic Pancreatic Cancer: A Systematic Review and Meta-Analysis.
Gemcitabine and nab-paclitaxel (GEM-NAB) and the combination of 5-fluorouracil, oxaliplatin, and irinotecan (FOLFIRINOX) are valid first-line options for advanced or metastatic pancreatic cancer (mPC). However, no randomized trials comparing the two schemes have been performed. This meta-analysis aims to compare GEM-NAB and FOLFIRINOX in terms of safety and effectiveness, taking into account data from real-life studies on mPC. We systematically searched PubMed, EMBASE and Cochrane library up to November 2018 to identify retrospective or cohort studies on mPC comparing GEM-NAB and FOLFIRINOX. We included 16 retrospective studies, including 3813 patients (2123 treated with GEM-NAB and 1690 treated with FOLFIRINOX). Despite a median weighted overall survival (OS) difference in favor of FOLFIRINOX (mean difference: 1.15, 95% confidence interval CI 0.08⁻2.22, = 0.03), in whole population OS was similar (hazard ratio (HR = 0.99, 95% CI 0.84⁻1.16; = 0.9). PFS was also not different between the two arms (HR = 0.88, 95% CI 0.71⁻1.1; = 0.26). The overall response rate was similar (25 vs. 24% with GEM-NAB and FOLFIRINOX). Among grade 3⁻4 toxicities, neutropenia, febrile neutropenia, and nausea were lower with GEM-NAB, while neurotoxicity and anemia were lower with FOLFIRINOX. In conclusion, despite a numerically longer median OS with FOLFIRINOX as compared to GEM-NAB, the overall risk of death and progression were similar. Their toxicity was different with less nausea, neutropenia, and febrile neutropenia with GEM-NAB, as compared to less neurotoxicity and anemia with FOLFIRINOX. Therefore, analysis of non-randomized "real world" studies to date has not provided evidence of a major benefit of one regimen over the other.

Meta-Analysis
Paclitaxel remains the first-line chemotherapy regimen for many malignant tumors. However, prognosis and adverse events under different dosing regimens (one-week versus three-week treatment) remain contradictory in many randomized controlled trials (RCTs). Here, we performed a comprehensive meta-analysis to measure the efficacy and toxicities of these two dosing regimens. Four databases were systematically retrieved. RCTs comparing two paclitaxel dosing regimens for advanced malignant tumors with assessable outcomes (e.g., overall survival (OS), progression-free survival (PFS), toxicities, response rates) were included. In total, 19 eligible RCTs involving 9 674 patients were included. Meta-analysis of pan-cancers revealed that weekly paclitaxel treatment was more beneficial regarding PFS compared to three-week paclitaxel treatment (hazard ratio (HR) = 0.90, 95% confidence interval (CI) = 0.82-0.99, = 0.02). Nevertheless, there was no significant difference in terms of OS between the two dosing regimens (HR = 0.98, 95%CI = 0.91-1.06, = 0.62) or other tested subgroups. In terms of serious adverse events, grade 3 or 4 (G3/4) neutropenia, G3/4 febrile neutropenia, G3/4 arthritis, and G3/4 alopecia occurred less often under weekly paclitaxel treatment. In summary, Weekly paclitaxel treatment demonstrates better PFS and fewer chemotherapy-induced hematological and non-hematological toxicities compared to the three-week paclitaxel regimen.

Meta-Analysis
CONTEXT
Urethral stricture disease (USD) is initially managed with minimally invasive techniques such as urethrotomy and urethral dilatation. Minimally invasive techniques are associated with a high recurrence rate, especially in recurrent USD. Adjunctive measures, such as local drug injection, have been used in an attempt to reduce recurrence rates.
OBJECTIVE
To systematically review evidence for the efficacy and safety of adjuncts used alongside minimally invasive treatment of USD.
EVIDENCE ACQUISITION
A systematic review of the literature published between 1990 and 2020 was conducted in accordance with the PRISMA checklist.
EVIDENCE SYNTHESIS
A total of 26 studies were included in the systematic review, from which 13 different adjuncts were identified, including intralesional injection (triamcinolone, n = 135; prednisolone, n = 58; mitomycin C, n = 142; steroid-mitomycin C-hyaluronidase, n = 103, triamcinolone-mitomycin C-N-acetyl cysteine, n = 50; platelet-rich plasma, n = 44), intraluminal instillation (mitomycin C, n = 20; hyaluronic acid and carboxymethylcellulose, n = 70; captopril, n = 37; 192-iridium brachytherapy, n = 10), application via a lubricated catheter (triamcinolone, n = 124), application via a coated balloon (paclitaxel, n = 106), and enteral application (tamoxifen, n = 30; deflazacort, n = 36). Overall, 13 randomised controlled trials were included in the meta-analysis. Use of any adjunct was associated with a lower rate of USD recurrence (odds ratio [OR] 0.37, 95% confidence interval [CI] 0.27-0.50; p < 0.001) compared to no adjunct use. Of all the adjuncts, mitomycin C was associated with the lowest rate of USD recurrence (intralesional injection: OR 0.23, 95% CI 0.11-0.48; p < 0.001; intraluminal injection: OR 0.11, 95% CI 0.02-0.61; p = 0.01). Urinary tract infection (2.9-14%), bleeding (8.8%), and extravasation (5.8%) were associated with steroid injection; pruritis of the urethra (61%) occurred after instillation of captopril; mild gynaecomastia (6.7%) and gastrointestinal side effects (6.7%) were associated with oral tamoxifen.
CONCLUSIONS
Adjuncts to minimally invasive treatment of USD appear to lower the recurrence rate and are associated with a low adjunct-specific complication rate. However, the studies included were at high risk of bias. Mitomycin C is the adjunct supported by the highest level of evidence.
PATIENT SUMMARY
We reviewed studies on additional therapies (called adjuncts) to minimally invasive treatments for narrowing of the urethra in men. Adjuncts such as mitomycin C injection result in a lower recurrence rate compared to no adjunct use. The use of adjuncts appeared to be safe and complications are uncommon; however, the studies were small and of low quality.

Review
BACKGROUND
Lung cancer remains a devastating disease with few effective treatment options. Recent developments in chemotherapy have led to cautious optimism. This paper reviews the evidence on the clinical and cost effectiveness of four of the new generation drugs for patients with lung cancer.
METHODS
A systematic review of randomised controlled trials (RCTs) identified from 11 electronic databases (including Medline, Cochrane library and Embase), reference lists and contact with experts and industry was performed to assess clinical effectiveness of paclitaxel, docetaxel, gemcitabine and vinorelbine. Clinical effectiveness was assessed using the outcomes of patient survival, quality of life, and adverse effects. Cost effectiveness was assessed by development of a costing model and presented as incremental cost per life year saved (LYS) compared with best supportive care (BSC).
RESULTS
Of the 33 RCTs included, five were judged to be of good quality, 10 of adequate quality, and 18 of poor quality. Gemcitabine, paclitaxel, and vinorelbine as first line treatment and docetaxel as second line treatment appear to be more beneficial for non-small cell lung cancer than BSC and older chemotherapy agents, increasing patient survival by 2-4 months against BSC and some comparator regimes. These gains in survival do not appear to be at the expense of quality of life. Survival gains were delivered at reasonable levels of incremental cost effectiveness for vinorelbine, vinorelbine with cisplatin, gemcitabine, gemcitabine with cisplatin, and paclitaxel with cisplatin regimens compared with BSC.
CONCLUSION
Although the clinical benefits of the new drugs appear relatively small, their benefit to patients with lung cancer appears to be worthwhile and cost effective.

Review
This review article describes studies published over the past five years on the combination of polyphenols, which are the most studied in the field of anticancer effects (curcumin, quercetin, resveratrol, epigallocatechin gallate, and apigenin) and chemotherapeutics such as cisplatin, 5-fluorouracil, oxaliplatin, paclitaxel, etc. According to WHO data, research has been limited to five cancers with the highest morbidity rate (lung, colorectal, liver, gastric, and breast cancer). A systematic review of articles published in the past five years (from January 2018 to January 2023) was carried out with the help of all Web of Science databases and the available base of clinical studies. Based on the preclinical studies presented in this review, polyphenols can enhance drug efficacy and reduce chemoresistance through different molecular mechanisms. Considering the large number of studies, curcumin could be a molecule in future chemotherapy cocktails. One of the main problems in clinical research is related to the limited bioavailability of most polyphenols. The design of a new co-delivery system for drugs and polyphenols is essential for future clinical research. Some polyphenols work in synergy with chemotherapeutic drugs, but some polyphenols can act antagonistically, so caution is always required.

Review
Therapy with gemcitabine and nab-paclitaxel (GNP) is the most commonly used palliative chemotherapy, but its advantage in the neoadjuvant setting remains unclear. Accordingly, our aim is to evaluate the impact of first-line neoadjuvant therapy with GNP in patients with borderline resectable (BRPC) and locally advanced pancreatic cancer (LAPC). A systematic search for published studies until August 2020 was performed. The primary endpoint included resection and R0 resection rates in the intention-to-treat population. Secondary endpoints were response rate, survival and toxicity. Among 21 studies, 950 patients who received neoadjuvant GNP were evaluated. Treatment with GNP resulted in surgical resection and R0 resection rates as follows: 49% (95% CI 30-68%) and 36% (95% CI 17-58%) for BRPC and 16% (95% CI 7-26%) and 11% (95% CI 5-19%) for LAPC, respectively. The objective response rates and the median overall survival (mOS) ranged from 0 to 67% and 12 to 30 months, respectively. Neutropenia (range 5-77%) and neuropathy (range 0-22%) were the most commonly reported grade 3 to 4 adverse events. Neoadjuvant chemotherapy with GNP can be performed safely and with valuable effects in patients with BRPC and LAPC. The utility of GNP in comparison to FOLFIRINOX in the neoadjuvant setting requires further investigation in prospective randomized trials.
