UNASSIGNED: Diffuse intrinsic pontine glioma (DIPG) stands as the predominant type of brainstem glioma. It is characterized by a notably brief median survival period, with the majority of patients experiencing disease progression within six months following radiation therapy. This systematic review and meta-analysis aims to assess the efficacy and safety of hypofractionated radiotherapy (HFRT) compared to conventionally fractionated radiotherapy (CFRT) in DIPG treatment.
UNASSIGNED: A systematic literature search was conducted in four databases, and relevant studies comparing HFRT and CFRT in DIPG were included. Data were extracted and analyzed for overall survival (OS), progression-free survival (PFS), and treatment-related toxicities. Statistical analysis was performed using random-effects models with heterogeneity assessment.
UNASSIGNED: Five studies met the inclusion criteria, comprising 518 patients. No significant difference in one-year OS was observed between HFRT and CFRT (29% vs. 22%, p = 0.94). The median OS was similar in both treatment groups (9.7 vs. 9.3 months, p = 0.324). Similarly, no significant difference in one-year PFS was found between HFRT and CFRT (19.8% vs. 16.6%, p = 0.82), with comparable median PFS (9.3 vs. 9.4 months, p = 0.20). In meta-regression analysis, there was no association of chemotherapy (p > 0.05) or radiation biologically effective dose (BED) (p > 0.05) regarding OS or PFS outcomes. There were no significant differences in treatment-related toxicities.
UNASSIGNED: HFRT yields one-year OS and PFS rates similar to CFRT in DIPG, with no significant differences in treatment-related toxicities. Chemotherapy and BED did not affect OS or PFS.

BACKGROUND: Systemic conversion therapy provides patients with initially unresectable hepatocellular carcinoma (HCC) the chance to salvage radical liver resection and superior survival outcomes, but the optimal conversion strategy is unclear.
METHODS: A systematic literature search was conducted on PubMed, EMBASE, Web of Science, Scopus, and the Cochrane Library between 2007 and 2024 focusing on studies reporting conversion therapy for HCC. The treatment groups were divided into Tyrosine kinase inhibitors (TKI), TKI plus loco-regional therapy (LRT), TKI plus anti-PD-1 therapy (TKI + PD-1), TKI + PD-1 + LRT, immune checkpoint inhibitors (ICI) plus LRT, and Atezolizumab plus bevacizumab (A + T) groups. The conversion to surgery rate (CSR), objective response rate (ORR), grade ≥ 3 treatment-related adverse events (AEs), overall survival (OS) and progression-free survival (PFS) were analyzed.
RESULTS: 38 studies and 4,042 patients were included. The pooled CSR were 8% (95% CI, 5-12%) in TKI group, 13% (95% CI, 8-19%) in TKI + LRT group, 28% (95% CI, 19-37%) in TKI + PD-1 group, 33% (95% CI, 25-41%) in TKI + PD-1 + LRT group, 23% (95% CI, 1-46%) in ICI + LRT group, and 5% (95% CI, 3-8%) in A + T group, respectively. The pooled HR for OS (0.45, 95% CI, 0.35-0.60) and PFS (0.49, 95% CI, 0.35-0.70) favored survival benefit of conversion surgery. Subgroup analysis revealed that lenvatinib + PD-1 + LRT conferred higher CSR of 35% (95% CI, 26-44%) and increased ORR of 70% (95% CI, 56-83%).
CONCLUSIONS: The current study indicates that TKI + PD-1 + LRT, especially lenvatinib + PD-1 + LRT, may be the superior conversion therapy with a manageable safety profile for patients with initially unresectable HCC. The successful conversion therapy favors the superior OS and PFS compared with systemic treatment alone.

UNASSIGNED: Ovarian cancer (OC) is a major gynecological malignancy with varying prognosis. The Neutrophil-toLymphocyte Ratio (NLR) has been proposed as a potential prognostic biomarker. This study aimed to evaluate the prognostic and clinical value of NLR in OC.
UNASSIGNED: A systematic review and meta-analysis were performed following PRISMA guidelines, including studies that evaluated the association between NLR and survival outcomes in OC patients. Search was performed in PubMed, Embase, Web of Science, and Cochrane Library databases. Quality assessment was done using Newcastle-Ottawa Scale (NOS). Heterogeneity was assessed, and pooled hazard ratios (HRs) were calculated using fixed or random-effects models as appropriate.
UNASSIGNED: Sistematski pregled i meta-analiza su obavljeni u skladu sa smernicama PRISMA, uključujući studije koje su procenile povezanost između NLR i ishoda preživljavanja kod pacijenata sa OC. Pretraga je obavljena u bazama podataka PubMed, Embase, Web of Science i Cochrane Library. Procena kvaliteta je urađena korišćenjem Njukasl-Otava skale (NOS). Heterogenost je procenjena, a udruženi odnosi opasnosti (HRs) su izračunati korišćenjem modela fiksnih ili slučajnih efekata prema potrebi.
UNASSIGNED: Analizirano je dvadeset studija koje su uključivale različite etničke pripadnosti, uzraste i veličinu uzorka. Utvrđeno je da je visok NLR u obrnutoj korelaciji sa ukupnim preživljavanjem (OS) (HR=1,21, 95% CI 1,09-1,34, P<0,001) i preživljavanjem bez progresije (PFS) (HR=1,20, 95% CI 1,03-1,38, P<0,001). Stratifikovane analize su pokazale jaču povezanost kod azijskih pacijenata, studije sa manjim veličinama uzoraka, mlađim pacijentima i višim graničnim vrednostima NLR.
UNASSIGNED: Meta-analiza sugeriše značajnu inverznu povezanost između NLR i ishoda preživljavanja kod pacijenata sa OC, naglašavajući potencijal NLR-a kao jednostavnog, isplativog prognostičkog biomarkera. Međutim, značajna heterogenost i uticaj zbunjujućih faktora naglašavaju potrebu za daljim istraživanjem.

This study aims to evaluate the prognostic role of the KRAS G12C mutation in patients with advanced non-small cell lung cancer and PD-L1 expression ≥50% who are treated with immune checkpoint inhibitor monotherapy.
We conducted a systematic review of clinical studies fulfilling the following criteria: (1) enrolling patients with advanced/metastatic non-small cell lung cancer with high PD-L1 tumour expression receiving first-line therapy with anti-PD-(L)1 immune checkpoint inhibitors; (2) comparing the outcomes of patients with the KRAS G12C mutation to those without this mutation, and (3) reporting overall survival and progression-free survival (PFS). The electronic databases Medline, EMBASE, Cochrane and Google Scholar, along with reference lists, were systematically searched.
We identified four publications that fulfilled the inclusion criteria, comprising a total of 469 patients. Of these, two studies reported hazard ratios (HR) for PFS, resulting in a final pooled patient sample of 163 for the meta-analysis. In patients with non-small cell lung cancer who received anti-PD-(L)1 monotherapy, the presence of a KRAS G12C mutation was associated with improved PFS compared to patients with KRAS wild-type tumours, with a pooled hazard ratio of 0.39 and a 95% Confidence Interval (CI) of 0.25-0.63. Among all patients with KRAS mutations, those harbouring a KRAS G12C mutation had improved PFS compared to patients with any other KRAS mutation (pooled HR 0.33, 95% CI 0.19-0.57).
Patients with non-small cell lung cancer who have the KRAS G12C mutation and high PD-L1 expression demonstrate favourable PFS with first-line PD-(L)1 immune checkpoint inhibitor monotherapy compared to patients with KRASwt or other KRAS mutations and high PD-L1 expression.

UNASSIGNED: This scoping review and meta-analysis aimed to map the evidence regarding prognostic factors in Chinese patients with immunoglobulin light chain (AL) amyloidosis and to identify current research gaps.
UNASSIGNED: We searched EMBASE, PubMed, and CNKI databases from their inception to 15 September 2021. All studies investigated the association between any prognostic factor and target outcomes, including overall survival (OS), progression-free survival (PFS), and end-stage renal disease (ESRD) in Chinese patients with AL amyloidosis.
UNASSIGNED: This scoping review included 52 studies, of which 44 with 6,432 patients contributed to the multivariate prognostic analysis. Multivariate analysis identified a total of 106 factors that correlated with OS, 16 factors with PFS, and 18 factors with ESRD. Five prognostic factors were significantly associated with PFS, and 11 prognostic factors were significantly associated with ESRD. Meta-analysis was only available for prognostic factors without heterogeneous cutoff values, for which hazard ratios (HRs) and their 95% confidence intervals (CIs) were reported. Meta-analysis showed that bone marrow plasma cells (BMCs) (HR: 1.96, 95% CI: 1.21-3.19, p < 0.05) and interventricular septal thickness (IVST) (HR: 1.23, 95% CI: 1.10-1.38, p < 0.05) were independently associated with OS.
UNASSIGNED: The significant prognostic factors associated with OS, PFS, and ESRD in Chinese patients with AL amyloidosis were related to plasma cell tumor load, biological characteristics, cardiac involvement, renal involvement, population characteristics, and treatment. Further studies should explore additional prognostic factors in patients with AL amyloidosis to develop prognostic models.

OBJECTIVE: This meta-analysis aimed to compare the prognosis of lung transplantation recipients based on donor age.
METHODS: A detailed search was performed in PubMed, Embase, Web of Science, and the Cochrane Library for cohort studies on lung transplantation. The prognosis of lung transplant recipients was investigated based on the donor age, with the primary outcomes being 1-year overall survival (OS), 3-year OS, 5-year OS, and 5-year chronic lung allograft dysfunction (CLAD)-free survival.
RESULTS: This meta-analysis included 10 cohort studies. Among the short-term outcomes, the older donor group demonstrated no significant difference from the young donor group in primary graft dysfunction within 72 hours, use of extracorporeal membrane oxygenation, length of ventilator use, and intensive care unit hours. However, a longer hospital stay was associated with the older donor group. In terms of long-term outcomes, no difference was found between the two groups in 1-year OS, 3-year OS, and 5-year OS. Notably, patients with older donors exhibited a superior 5-year CLAD-free survival.
CONCLUSIONS: The results of this meta-analysis indicate that older donors are not inferior to younger donors in terms of long-term and short-term recipient outcomes. Lung transplantation using older donors is a potential therapeutic option after rigorous evaluation.

BACKGROUND: Lung cancer, accounting for a significant proportion of global cancer cases and deaths, poses a considerable health burden. Non-small cell lung cancer (NSCLC) patients have a poor prognosis and limited treatment options due to late-stage diagnosis and drug resistance. Dysregulated of the mitogen-activated protein kinase (MAPK) pathway, which is implicated in NSCLC pathogenesis, underscores the potential of MEK inhibitors such as binimetinib. Despite promising results in other cancers, comprehensive studies evaluating the safety and efficacy of binimetinib in lung cancer are lacking. This systematic review aimed to investigate the safety and efficacy of binimetinib for lung cancer treatment.
METHODS: We searched PubMed, Scopus, Web of Science, and Google Scholar until September 2023. Clinical trials evaluating the efficacy or safety of binimetinib for lung cancer treatment were included. Studies were excluded if they included individuals with conditions unrelated to lung cancer, investigated other treatments, or had different types of designs. The quality assessment was conducted utilizing the National Institutes of Health tool.
RESULTS: Seven studies with 228 participants overall were included. Four had good quality judgments, and three had fair quality judgments. The majority of patients experienced all-cause adverse events, with diarrhea, fatigue, and nausea being the most commonly reported adverse events of any grade. The objective response rate (ORR) was up to 75%, and the median progression-free survival (PFS) was up to 9.3 months. The disease control rate after 24 weeks varied from 41% to 64%. Overall survival (OS) ranged between 3.0 and 18.8 months. Notably, treatment-related adverse events were observed in more than 50% of patients, including serious adverse events such as colitis, febrile neutropenia, and pulmonary infection. Some adverse events led to dose limitation and drug discontinuation in five studies. Additionally, five studies reported cases of death, mostly due to disease progression. The median duration of treatment ranged from 14.8 weeks to 8.4 months. The most common dosage of binimetinib was 30 mg or 45 mg twice daily, sometimes used in combination with other agents like encorafenib or hydroxychloroquine.
CONCLUSIONS: Only a few studies have shown binimetinib to be effective, in terms of improving OS, PFS, and ORR, while most of the studies found nonsignificant efficacy with increased toxicity for binimetinib compared with traditional chemotherapy in patients with lung cancer. Further large-scale randomized controlled trials are recommended.

UNASSIGNED: Multiple myeloma is a malignant tumour of the blood in which abnormal proliferation of plasma cells leads to bone destruction, renal impairment, anaemia, and hypercalcaemia. Renal impairment caused by multiple myeloma is a common and serious condition; however, the prognosis of multiple myeloma at the time of diagnosis remains unclear.
UNASSIGNED: We conducted searches for literature in PubMed, Web of Science, Cochrane, Embase, CNKI, Wanfang, and VIP databases up to 30 April 2023. Progression-free survival and overall survival with and without renal impairment at the time of multiple myeloma diagnosis were compared, and prognostic indicators were analysed.
UNASSIGNED: Six studies were finally included. Among patients with multiple myeloma, 319 had renal impairment, and 1166 had no renal impairment. Compared to the control group, no significant difference was observed in overall or progression-free survival in patients with multiple myeloma complicated with renal impairment.
UNASSIGNED: The limited low-quality evidence available does not support an association between prognosis and multiple myeloma complicated by kidney injury.

UNASSIGNED: Poly (ADP-Ribose) Polymerase (PARP) inhibitors represent a novel class of drugs that hinder DNA repair mechanisms in tumor cells, leading to cell death. This systematic review aims to evaluate the effectiveness, safety, and potential adverse effects of PARP inhibitors (PARPi) in the management of patients with advanced lung cancer.
UNASSIGNED: We conducted a comprehensive search for relevant studies in PubMed, Embase, Cochrane, and ClinicalTrials.gov. We extracted primary and secondary outcome measures, including progression-free survival (PFS), overall survival (OS), and adverse events (AEs), from the identified literature for subsequent meta-analysis and systematic review.
UNASSIGNED: This study encompassed twelve randomized controlled trials, involving 3,132 patients with advanced lung cancer. In comparison to non-PARPi treatments, the administration of PARPi significantly extended OS (hazard ratio (HR) = 0.90, 95% CI = 0.83-0.97, p = 0.006). However, the difference in PFS did not reach statistical significance.
UNASSIGNED: In summary, therapies incorporating PARPi provide a degree of benefit by extending OS in patients with advanced lung cancer. Nonetheless, further trials are necessary to furnish additional evidence regarding the efficacy and safety of PARPi in the treatment of lung cancer.

BACKGROUND: Intraventricular meningioma (IVM) is a rare subtype of intracranial meningioma, accounting for 9.8 to 14% of all intraventricular tumors. Currently, there is no clear consensus on which patients with IVM should receive conservative treatment, surgery, or stereotactic radiosurgery (SRS). This research aims to analyze the outcomes, including survival and recurrence rates of patients who undergo SRS for IVM as a primary or adjuvant treatment.
METHODS: A systematic search was conducted in Scopus, Web of Science, PubMed, and Embase till June 5th 2023. Screening and data extraction were performed by two independent authors. Random-effect meta-analysis was performed to determine the tumor control proportion of IVM cases treated with SRS. Individual patient data (IPD) meta-analysis was performed for the progression-free survival (PFS) of the patients in the follow-up time. All analyses were performed using the R programming language.
RESULTS: Out of the overall 132 records, 14 were included in our study, of which only 7 had enough data for the meta-analysis. The tumor control proportion was 0.92 (95% CI, 0.69-0.98) in patients who underwent SRS for primary IVM. The overall tumor control in both primary and adjuvant cases was 0.87 (95% CI, 0.34-0.99). the heterogeneity was not significant in both meta-analyses (P = 0.73 and P = 0.92, respectively). Post-SRS perifocal edema occurred in 16 out of 71 cases (0.16; 95% CI, 0.03-0.56), with no significant heterogeneity (P = 0.32). IPD meta-analysis showed a PFS of 94.70% in a 2-year follow-up. Log-rank test showed better PFS in primary SRS compared to adjuvant SRS (P < 0.01).
CONCLUSIONS: According to this study, patients with IVM can achieve high rates of tumor control with a low risk of complications when treated with SRS, regardless of whether they have received prior treatment. Although SRS could be a promising first-line treatment option for asymptomatic IVM, its efficacy in symptomatic patients and its comparison with resection require further investigation.
