Meta-Analysis
OBJECTIVE
Neuroblastoma is a common extracranial solid tumor of childhood. Recently, multiple treatments have been practiced including Iodine-131-metaiodobenzylguanidine radiation (I-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 I-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 I-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 I-MIBG monotherapy were 39%, 31%, 22% and 15%, respectively. The pooled objective response rate of I-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 I-MIBG combined with other therapies, the pooled occurrence rates of thrombocytopenia and neutropenia were 79% and 78%.
CONCLUSION
I-MIBG treatment alone or in combination of other therapies is effective on clinical outcomes in the treatment of neuroblastoma, individualized I-MIBG is recommended on a clinical basis.

There are several case reports suggesting that G-CSFs may, in rare conditions, produce serious side effects, such as vasculitis. A systematic search was conducted in Medline via PubMed, Embase and Cochrane Library to describe this unusual side effect to raise awareness among clinicians for early recognition and treatment. Fifty-seven patients were analyzed. The most prevalent cancer type was breast cancer (47%). Long-acting G-CSF was used in 38 patients (67%). Only 47% of patients were treated with steroids. Although the benefit of G-CSF treatment outweighs the potential damage, oncologists should consider the possibility of triggering a vascular toxicity and try to identify patients at increased risk for this side effect.

Clozapine is an atypical antipsychotic used for the treatment of resistant schizophrenia, exhibiting significant advantages over other antipsychotic agents. Clozapine efficacy is well established in people diagnosed with schizophrenia via reducing both positive and negative symptoms. Also, is associated with a low risk of extrapyramidal side effects compared to other antipsychotics. Despite the above, clozapine is an unpopular therapeutic option for patients not previously responded to other antipsychotics, because of adverse side effects, such as hyper-salivation and weight gain or critical side effects, i.e., risk for developing neutropenia and agranulocytosis and the need for a systematic and vigilant patients' monitoring, causing discomfort to them and increased expenses to the healthcare system. The aim of the present article is to describe (a) the development of a "clozapine treatment monitoring protocol", and (b) the monitoring process applied at the Department of Psychiatry of Aghioi Anargyroi Cancer Hospital in patients under clozapine treatment. For the protocol development a systematic review of the existing literature was conducted. An advanced search in Medline, CINAHL, Scopus and Google Scholar was conducted, as well as at the National Organization of Greece for Medicines database, with the following key- words: "clozapine", "clozapine protocol", "clozapine monitoring", "clozapine guidelines". Based on this procedure, the Victorian Consensus View protocol applied in Australia was evaluated as the most appropriate since it encompasses: (a) monitoring of multiple systems based on a holistic healthcare approach towards patients, and (b) Intense cardiovascular functioning monitoring, highly relevant to the Greek population due to increased incidence of myocarditis. Overall, the necessary interventions prior and after clozapine treatment initiation are, monitoring of heamatological and cardiovascular function and related side effects, metabolic monitoring and related side effects, monitoring of metabolic adverse effects, gastrointestinal and neurological adverse effects, hepatic function monitoring and related side effects. Clozapine treatment monitoring protocol applied at special settings, e.g., Clozapine Clinics, is highly beneficial, since the risk of neutropenia, agronulocytosis is minimized, while suicidal behavior and substance use are reduced along with risky health behaviors, i.e., nicotine use and sedentary lifestyle. The current protocol may be applied by mental healthcare professionals aiming to empower individuals with schizophrenia through promoting their independency and quality of life.

Meta-Analysis
This meta-analysis was conducted to evaluate the efficacy and safety of the addition of Traditional Chinese Medicine (TCMs) to capecitabine-based regimens for colorectal cancer (CRC) in term of tumor. The eight electronic databases including Cochrane Library, PubMed, Web of Science (WOS), Excerpt Medica Database (Embase), Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Chinese Science and Technology Journals (CQVIP), and Wanfang Database were systematically searched for eligible studies from their inception to March 2021. Thirty-nine randomized controlled trials were involved in this study, and all the data were analyzed by Review Manager 5.3 (Nordic Cochran Centre, Copenhagen, Denmark) and R 4.0.5 software. The meta-analyses suggested that TCMs in combination with capecitabine-based regimens increased objective response rate (ORR) in the palliative treatment of CRC (risk ratio [RR], 1.35 [1.17, 1.55], I = 0%), disease control rate (DCR) (RR, 1.22 [1.12, 1.32], I = 3%), and quality of life (QOL) (RR, 1.71 [1.44, 2.03], I = 0%), with decreased risks of myelosuppression, anemia, thrombocytopenia, liver/renal dysfunction, neurotoxicity, nausea/vomiting, neutropenia, diarrhea, leukopenia, improved the peripheral lymphocyte, reduced the expression of tumor markers, and related factors. Further sensitivity analysis of specific plant-based TCMs found that dangshen, fuling, and gancao had significantly higher contributions to the results of the RR. The results show that capecitabine-based chemotherapy combined with TCM in the treatment of CRC increases the efficiency of ORR and DCR, reduces chemotherapeutic agents-associated adverse reactions, and improves their life quality as compared with chemotherapy alone, but further randomized and large sample of studies are needed.

Meta-Analysis
Bruton tyrosine kinase inhibitors (BTKi) are important treatment options in Waldenström's macroglobulinemia (WM). Whether second-generation BTKi are associated with improved outcomes and/or better safety profile remains unclear. We did a systematic review and meta-analysis of clinical trials that reported data on the outcomes of patients with WM who received either first- or second-generation BTKi in the period between January 2010 and August 2021. Studies with twenty or fewer patients were excluded. The primary outcomes were efficacy measured by response and survival data. Eleven studies met the eligibility criteria and were included in the final analysis (n = 730 patients). A total of 298 patients received 1st-generation BTKi and 432 received a 2nd-generation BTKi. Pooled overall response rate (ORR) and major response rate (MRR) for both generations were similar (94.2% and 78.5% in 1st vs. 88.9% and 75.1% in 2nd, respectively). MRR for both generations was higher in MYD88 Mut/CXCR4 WT patients compared to MYD88 Mut/CXCR4 Mut patients (odds ratio [OR]: 3.9, 95% CI: 2.2 to 5.5). Pooled 18-mo progression-free survival (PFS) was similar for both generations (88.5% vs. 87.3%). Grade 3/4 atrial fibrillation was higher in 1st-generation BTKi (3.1% vs. 0.4%); however, grade-3/-4 infections and neutropenia were more frequent in 2nd-generarion BTKi (20.9% vs. 13.2%, 17.7% vs. 12%, respectively). The efficacy of 1st- and 2nd-generation BTKis is comparable. The 1st-generation BTKi were associated with a higher risk of atrial fibrillation, whereas infections and neutropenia occurred more frequently in 2nd-generation BTKi.

Sorafenib exhibits lower toxicity and comparable efficacy to sunitinib as a first-line treatment for metastatic renal cell carcinoma: A systematic review and meta-analysis.
BACKGROUND
To assess the safety and efficacy of sorafenib and sunitinib as first-line treatments for metastatic renal cell carcinoma (mRCC), to provide evidence-based support for clinical decision-making regarding rational drug use.
METHODS
Until May 10, 2023, a comprehensive search was conducted across PubMed, EMBASE, Cochrane Library, ClinicalTrials.gov, China National Knowledge Infrastructure, and Wanfang databases to identify clinical studies comparing sorafenib with sunitinib as first-line treatment for mRCC. The literature was screened, data extracted, and quality evaluated independently by 2 researchers. Meta-analysis was conducted using Revman5.4 software.
RESULTS
A total of 3741 patients were enrolled in 20 studies. The meta-analysis results indicated that there were no significant differences in the 2- and 5-year progression-free survival (PFS) and overall survival (OS) rates between the sorafenib and sunitinib groups (P > .05). The disease control rate (DCR) was comparable between the 2 groups (P > .05), while the objective response rate (ORR) was higher in the sunitinib group (P = .03). However, subgroup analysis revealed no significant differences in ORR, DCR, 2- and 5-year PFS, and OS rates between sorafenib and sunitinib among both Asian populations as well as European and American populations (P > .05). In terms of drug-related adverse events, the incidence of grade ≥ 3 hypertension, leukopenia, neutropenia, thrombocytopenia, anemia, nausea and vomiting were significantly lower in the sorafenib group compared to the sunitinib group (P < .05).
CONCLUSION
In the first-line treatment of mRCC, sorafenib exhibits comparable efficacy to sunitinib but with lower toxicity.

BACKGROUND
Antipsychotics are a cornerstone of pharmacological treatment of schizophrenia. Improved understanding of the dose-response relationship of antipsychotics in terms of efficacy, adverse effects, and mortality can help to optimize the pharmacological treatment of schizophrenia.
METHODS
This narrative literature review summarizes current evidence on the relationship of antipsychotic dose with efficacy, adverse effects, and mortality in patients with schizophrenia.
RESULTS
The efficacy of antipsychotics generally appeared to be highly dose-dependent in the acute phase of schizophrenia, with each antipsychotic having a specific dose-response curve. The presence or absence of dose-dependency and its extent varied according to the type of adverse effect. Parkinsonism, hyperprolactinemia, weight gain, and neurocognitive impairment appeared to be dose-related. The following adverse effects might be at least somewhat dose-dependent: akathisia, tardive dyskinesia, osteoporosis, sexual dysfunction, diabetes mellitus, myocardial infarction, stroke, thromboembolism, QT interval prolongation, anticholinergic adverse effects, somnolence, pneumonia, hip fracture, and neuroleptic malignant syndrome. In contrast, the relationships of antipsychotic dose with dyslipidemia, hypotension, seizure, sialorrhea, and neutropenia and agranulocytosis remained unclear due to mixed findings and/or limited data. Although a higher lifetime cumulative antipsychotic dose might contribute to higher mortality, it is still difficult to conclude whether mortality increases in a dose-dependent manner.
CONCLUSION
These findings could help clinicians to optimize antipsychotic treatment in patients with schizophrenia by balancing risks and benefits in clinical practice. However, further investigations with larger sample sizes and more robust study designs that focus on each antipsychotic agent are needed.

BACKGROUND
Antipseudomonal β-lactams have been used for the treatment of febrile neutropenia (FN); however, the efficacy and safety of antipseudomonal β-lactams in pediatric patients remain unclear. The aim of this study was to comprehensively compare the efficacy and side effects of optional antipseudomonal β-lactams for pediatric FN.
METHODS
PubMed, Embase, Medline, and Cochrane Library were systematically searched from their inception to December 18, 2020. Eligible randomized controlled trials in which pediatric FN patients were treated with an empiric monotherapy of antipseudomonal β-lactams were selected. Data synthesis was performed using WinBUGS 14.0 software and meta packages implemented in R 3.6.2. Random-effects network meta-analysis was performed, and dichotomous data were pooled as odds ratios with 95% confidence intervals. The primary outcome was treatment success without modification; the secondary outcomes were adverse events (AEs), all-cause mortality, and new infections. The GRADE tool was used to assess the quality of the evidence. The protocol was registered with PROSPERO ID CRD42021226763.
RESULTS
Eighteen studies with 2517 patients were included. The results showed no statistically significant difference between the optional antipseudomonal β-lactams in the outcomes of treatment success without modification, all AEs, all-cause mortality, and new infections for pediatric FN. Based on the results of Bayesian rank probability, meropenem was ranked highest among all the treatment options with regard to treatment success without modification benefit; ceftazidime and meropenem were associated with a lower risk of AEs; cefoperazone/sulbactam and piperacillin/tazobactam were associated with a lower risk of mortality, and piperacillin/tazobactam and meropenem were associated with a lower risk of new infections. The quality of evidence was moderate.
CONCLUSIONS
Meropenem and piperacillin/tazobactam were found to be better with regard to treatment success without modification, with a comparable safety profile. Therefore, our findings support the use of meropenem and piperacillin/tazobactam as a treatment option for pediatric FN patients.

Meta-Analysis
OBJECTIVES
There is no meta-analysis about the effects of pegfilgrastim on the occurrence of febrile neutropenia (FN) in pediatric/adolescent cancer patients. The study explored the efficacy of prophylactic pegfilgrastim in preventing FN in children/adolescents with cancer.
METHODS
PubMed, Embase, and the Cochrane Library were searched for studies published before April 7, 2020. The primary outcome was the rate of FN. Effect size (ES) and odds ratio (OR) with 95% confidence intervals (CIs) were used to evaluate the outcome. The ES represented the rate of FN, and the STATA 'metaprop' command was used to synthesize the rate.
RESULTS
Eight studies were included, comprising 167 patients and 550 courses of treatment. There was no difference between pegfilgrastim and filgrastim for the rate of FN in children receiving chemotherapy (OR = 0.68, 95% CI: 0.20-2.23, = 0.520). In patients receiving pegfilgrastim, the rate of FN was 25.6% (95% CI: 14.9%-36.3%), the rate of grade 4 FN was 38.3% (95% CI: 19.2%-59.5%), the rate of severe neutropenia (SN) was 40.5% (95% CI: 35.1%-46.1%), and the rate of treatment delays due to FN was 4.8% (95% CI: 0.8%-11.3%).
DISCUSSION
The number of studies that could be included was small; therefore, a specific type of cancer or a specific treatment could be studied. Heterogeneity was high.
CONCLUSION
There was no difference between pegfilgrastim and filgrastim for the rate of FN. The use of pegfilgrastim was still associated with rates of FN, grade 4 FN, severe neutropenia, and treatment delays due to FN in pediatric cancer patients.

Granulocyte-colony-stimulating factor (G-CSF) is highly beneficial as a general treatment for anti-thyroid drug (ATD)-induced agranulocytosis. This meta-analysis aimed to assess the clinical effects of G-CSF and non-G-CSF on recovery duration in patients with ATD-induced agranulocytosis by analyzing the overall clinical outcomes. The PubMed, Embase, Ovid, Cochrane, Google Scholar, China National Knowledge Infrastructure (CNKI) databases were searched for published studies from 1900 to 2018. No language restriction was implemented. This meta-analysis included 10 published retrospective studies and one prospective study. Data were obtained from 11 trials (474 patients: 247 with G-CSF and 227 with non-G-CSF treatment). Compared with the non-G-CSF group, the G-CSF group presented shorter recovery duration [weighted mean difference (WMD) = -3.04 days, 95% confidence interval (95% CI): -4.38 to -1.69 ( = 4.43 = 0.000)]. However, the recovery duration varied across regions and recovery criteria. Asian patients achieved significant clinical outcomes [WMD = -3.16 days (95% CI: -4.58 to -1.74, = 0.000)] compared with European and South American patients [WMD = -2.19 days (95% CI: -7.38 to 3.01, = 0.409)]. Also, according to various recovery criteria, a duration of granulocyte count increase of more than 1.5 or 1.0 × 10/L [WMD = -3.50 days (95% CI: -4.82 to -2.18 = 0.000)] revealed a better treatment effect. G-CSF can significantly shorten the recovery duration in patients with ATD-induced agranulocytosis.
