INTRODUCTION
Lobaplatin is a new platinum-based cytotoxic chemotherapeutic agent. Endostar is an endogenous angiogenic inhibitor with implicated anti-tumor activity. This study was to investigate the efficacy and safety of thoracic perfusion of lobaplatin combined with endostar in the treatment of malignant pleural effusions (MPE).
METHODS
We searched the databases of Pubmed, the Cochrane Library, Embase, WanFang Data, and CNKI to select the studies regarding the efficacy and safety of lobaplatin combined with endostar to treat MPE. A total of 10[3-12] randomized controlled trials with 651 patients were included.
RESULTS
The objective response rate (P < .001, odds ratio = 4.08) and disease control rate (P < .001, odds ratio = 3.69) of lobaplatin combined with endostar were significantly higher than lobaplatin alone. In addition, lobaplatin combined with endostar remarkably promoted the quality of life of patients (P < .001, odds ratio = 3.93) compared with lobaplatin alone. Lobaplatin combined with endostar also promoted the quality of life of patients (P < .05, odds ratio = 2.56) compared with cisplatin combined with endostar. At the same time, the leukopenia rate (P < .05, odds ratio = .40) and the incidence of nausea and vomiting (P < .05, odds ratio = .38) of lobaplatin combined with endostar were significantly lower than that of cisplatin combined with endostar.
CONCLUSIONS
The efficacy of lobaplatin combined with endostar was superior to lobaplatin alone. The safety was higher than cisplatin combined with endostar through thoracic perfusion in treating MPE, which indicated that lobaplatin combined with endostar could be the effective agent for controlling MPE.

AIMS AND BACKGROUND
A number of population pharmacokinetic (PPK) models of anti-programmed cell death-1 (PD-1) monoclonal antibodies (mAbs) in multiple tumor types have been published to characterize the influencing factors of their pharmacokinetics. This review described PPK models of anti-PD-1 mAbs that investigate the magnitude and types of covariate effects in PK parameters, provide a reference for building PPK models of other anti-PD-1 mAbs, and identify areas requiring additional research to facilitate the application of PPK models.
METHODS
A systematic search for analyses of PPK models of eleven anti-PD-1 mAbs on the market that were carried out in humans was conducted using PubMed, Embase, and the Cochrane Library. The search covered the period from the inception of the databases to April 2022.
RESULTS
Currently, there are fourteen analyses on PPK models of anti-PD-1 mAbs summarized in this review, including seven models that refer to nivolumab, four referring to pembrolizumab, one referring to cemiplimab, one referring to camrelizumab, and one referred to dostarlimab. Most analyses described the pharmacokinetics of anti-PD-1 mAbs with a two-compartment model with time-varying clearance (CL) and a sigmoidal maximum effect. The estimated CL and volume of distribution in the central (V) ranged from 0.179 to 0.290 L/day and 2.98 to 4.46 L, respectively. The median (range) of interindividual variability (IIV) for CL and V was 30.9% (8.7%-50.8%) and 29.0% (4.32%-40.7%), respectively. The commonly identified significant covariates were body weight (BW) on CL and V, and albumin (ALB), tumor type, sex, and performance status (PS) on CL. Other less assessed significant covariates included lactate dehydrogenase (LDH), immunoglobulin G (IgG), ipilimumab coadministration (IPICO) on CL, and body mass index (BMI), malignant pleural mesothelioma (MESO) on V.
CONCLUSION
This review provides detailed information about the characteristics of PPK models of anti-PD-1 mAbs, the effects of covariates on PK parameters, and the current status of the application of the models. ALB, BW, specific tumor type, sex, and PS should be considered for the future development of the PPK model of anti-PD-1 mAbs. Other potential covariates that were assessed less frequently but still have significance (e.g., LDH, IgG, and IPICO) should not be ignored. Thus, further research and thorough investigation are needed to assess new or potential covariates, which will pave the way for personalized anti-PD-1 mAbs therapy.

Review
Primary effusion lymphoma (PEL) is a large B-cell lymphoma growing within body-cavities caused by the Kaposi sarcoma-associated herpesvirus (KSHV)/human herpesvirus-8 (KSHV/HHV-8). It is mainly reported in HIV-infected patients. The uncommon occurrence in the elderly supports a form paralleling classic Kaposi sarcoma (KS), i.e. classic PEL, whose characteristics are relatively underexplored. To better understand the diagnostic modalities and clinical-epidemiological features of classic PEL, articles reporting cases of PEL were identified through MEDLINE/EMBASE databases (January 1998-July 2020) and screened according to PRISMA guidelines to extract individual-level data. A comparison was also performed between classic PEL and classic KS to evaluate similarities and differences. We identified 105 subjects (median age 77 years; 86% males), mainly from Mediterranean countries (52%, first Italy) and Eastern Europe (7%). Common comorbidities were heart failure (32%), cirrhosis (16%), and malignancy (20%) including lymphoid neoplasms. Pleural cavity was the commonest site (67%). PEL diagnosis was based on cytomorphology (89%), evidence of KSHV/HHV-8 infection (94%), EBV co-infection (28%) and clonality of IGH (59%), IGK (14%), TRG (9%) alone or in multiple combinations. Compared to KS, age (P<.001), gender-ratio (P=.08) and mortality (P<.001) were significantly higher in PEL, whereas the frequency of PEL as a second primary was similar (P=.44). This is the first systematic review of classic PEL case reports highlighting heterogeneity and lack of a uniform multidisciplinary approach at diagnosis, in the absence of specific guidelines as it happens for rare cancers. It is conceivable that classic PEL is still underdiagnosed in Mediterranean countries wherein KSHV/HHV-8 is endemic.

BACKGROUND
Cellular immunotherapy has become a new and promising treatment for patients with liver tumor. However, as most immune cells are delivered by intravenous injection, the effect is limited and is likely to produce systemic toxicity. Here, the objective was to investigate the efficacy and safety of cellular immunotherapy by local infusion, which seems to be a promising approach and has not been well-studied.
METHODS
The PubMed, Web of Science, Embase, and Cochrane Library databases were searched to obtain literature. The overall response rate (ORR), overall survival (OS) rates, and adverse events were investigated to evaluate the effectiveness and safety of locoregional therapy. The methodological quality of the articles was assessed using the methodological index for non-randomized studies (MINORS) score. The meta-analysis was performed using Stata 15.0.
RESULTS
The eligible 17 studies involved a total of 318 patients. The random-effects model demonstrated that the ORR of local cell infusion therapy was 48% (95% confidence interval [CI]: 26%-70%). The pooled OS rate was 94% (95% CI: 83%-100%) at 6 months, 87% (95% CI: 74%-96%) at 12 months, and 42% (95% CI: 16%-70%) at 24 months. Subgroup analyses suggested that minimally invasive treatment and absence of metastasis were significantly associated with better ORR. Fourteen studies reported a variety of adverse events related to cell therapy by local perfusion. The most common complications after regional infusion of immune cells were myelosuppression (66%), fever (50%), gastrointestinal toxicity (22%), hepatic dysfunction (15%), and pleural effusion and/or ascites (14%).
CONCLUSIONS
Immune cell therapy through local perfusion is effective for patients with liver cancer, with manageable toxicity. It demonstrates better prognosis when combined with minimally invasive therapy. Considering the potential limitations, more randomized controlled trials are needed to provide solid evidence for our findings.

Meta-Analysis Review
The exact role of pleural effusion in the prognosis of cancer patients remains unclear. We aimed to systematically review the prognostic value of pleural effusion in patients with cancer. We performed a systematic review and meta-analysis with a systematic literature search. All cohort studies with available overall survival (OS) and progression-free survival (PFS) results for patients with cancer with or without pleural effusion were included. The Mantel-Haenszel method was used to calculate the pooled hazard ratios (HRs) and 95% confidence intervals (CIs). Heterogeneity and publication bias were examined. Subgroup analysis and sensitivity analysis were performed. A total of 47 studies with 146,117 patients were included in the analysis. For OS, pleural effusion was a prognostic factor associated with a poor prognosis for patients with cancer (HR, 1.58, 95% CI, 1.43-1.75; I 94.8%). In the subgroup analysis, pleural effusion was a prognostic factor associated with poor survival for patients with lung cancer (HR, 1.44, 95% CI, 1.35-1.54; I 60.8%), hematological cancer (HR, 2.79, 95% CI, 1.63-4.77; I 29.4%) and other types of cancer (HR, 2.08, 95% CI, 1.43-3.01; I 55.1%). For PFS, pleural effusion was a prognostic factor associated with a poor prognosis for patients with cancer (HR, 1.61, 95% CI, 1.28-2.03; I 42.9%). We also observed that massive pleural effusion was a prognostic factor associated with a poorer prognosis compared to minimal pleural effusion. Pleural effusion had prognostic value in both OS and PFS of patients with cancer, except for patients with malignant pleural mesothelioma, regardless of whether the malignant effusion was confirmed histologically or cytologically. However, future evidence of other pleural effusion characteristics is still needed.

BACKGROUND
Pleural effusion is characterized by excessive fluid collection in the pleural cavity. Black pleural effusion (BPE) is a rare entity with only limited scientific data. We aimed to review the current literature on black pleural effusion to characterize demographics, etiology, clinical presentation, pathological findings, available treatment strategies, and prognosis of this rare condition.
METHODS
We performed a systematic review of case reports and series and synthesized data on demographics, manifestations, management, and outcomes of patients with BPE. We searched Cochrane Library, PubMed, SCOPUS, and Google Scholar for any date until January 10, 2021. All studies (n = 31) that reported black pleural effusion in patients were added to the review. Prospective Register of Systematic Reviews registration number: CRD42020213839. Summary and descriptive analysis was performed on Jamovi version 1.2.
RESULTS
The mean age of 32 patients with BPE was 53 years, with male predominance (69%). The commonest risk factor was smoking (n = 9) followed by alcohol intake (n = 8). Dyspnea was the commonest symptom (n = 24, 75%). Pleural fluid was mostly exudative (n = 21). The commonest associated diagnosis was malignancy (n = 14), with 50% secondary to metastatic melanoma. The commonest intervention was therapeutic thoracocentesis (n = 25, 78%), and the effusion recurred in half of the cases where recurrence was reported (n = 13). In our review, we found the mortality rate to be at 20.8% (n = 20.8%). 58.3% of the patients were successfully treated and discharged home (n = 14).
CONCLUSION
Although rare, BPE appears to be a relevant symptom as it seems to be frequently associated with modifiable risk factors and underlying malignancy. Our systematic review substantiates a vital research gap as observational research is imperative to characterize BPE further and form a basis for designing tailored diagnostic, preventive, and therapeutic strategies for BPE.

Review
Hyperthermic intrathoracic chemotherapy for the treatment of malignant pleural effusion caused by breast and ovarian cancer: A systematic literature review and pooled analysis.
OBJECTIVES
Breast and ovarian cancer account for over 30% of malignant pleural effusions (MPEs). Treatment of the metastatic disease requires control of the MPE. Even though primarily symptomatic, the treatment of the MPE can potentially affect the oncological course of the disease. The aim of this review is to analyze the effectiveness of intrathoracic chemotherapy in the treatment of MPE caused by breast and ovarian cancer.
METHODS
A systematic literature research was conducted up until May 2021. Studies published in English on patients undergoing either surgical or interventional intrapleural chemotherapy were included.
RESULTS
Thirteen studies with a total of 497 patients were included. Analysis was performed on 169 patients with MPE due to breast cancer and eight patients with MPE secondary to ovarian cancer. The pooled success rates of intrathoracic chemotherapy for controlling the MPE were 59.1% and 87.5%, respectively. A survival analysis was not possible with the available data. The overall toxicity of the treatment was low.
CONCLUSIONS
Intrathoracic chemotherapy achieves symptomatic control of the MPE in 59.1% of patients with metastatic breast cancer and 87.5% of patients with metastatic ovarian cancer. This is inferior to other forms of surgical pleurodesis. Data from small case series and studies on intraperitoneal chemotherapy show promising results. However, formal oncological studies on the use of intrathoracic chemotherapy for metastatic breast or ovarian cancer are lacking. Further prospective pilot studies are needed to assess the therapeutic oncological effects of this treatment.

Meta-Analysis Review
INTRODUCTION
Advanced stage malignant mesothelioma (asMM) patients have poor prognosis. Several trials investigated the role of programmed cell death protein-1 (PD-1) and its ligand 1 (PD-L1) immune checkpoint inhibitors (ICIs) in pre-treated asMM.
METHODS
A systematic review of the literature of clinical trials testing single-agent anti PD-1/PD-L1 ICIs in pre-treated asMM was performed. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS) and overall survival (OS) data were extracted. The predictive role of PD-L1 was assessed.
RESULTS
We selected 13 studies including 888 patients. ORR and DCR were 18.1% (95% confidence interval [CI] 13.9-22.8%) and 55.4% (95% CI: 48.1-62.5%), respectively. Median PFS and OS ranged from 2.1 to 5.9 and from 6.7 to 20.9 months, respectively. ORR according to PD-L1 was 27.0% (95% CI: 18.7-36.2%).
CONCLUSIONS
Anti-PD-(L)1 ICIs might be considered a treatment option for chemotherapy-resistant asMM, even if reliable predictive factors are still lacking.

To clarify the predominance of Th1 or Th2 immune responses in malignant and tuberculous pleural effusion (MPE and TPE, respectively), we performed a meta-analysis of previously published results of the levels of Th1/Th2 cytokines associated with these two types of pleural effusion to evaluate the use of Th1/Th2 cytokine profiles in distinguishing TPE from MPE. We searched the PubMed and EMBASE databases for studies indexed from 2000 to March 2021. We included studies that (a) diagnosed TPE and MPE based on culture or pleural tissue biopsy and that (b) compared levels of Th1/Th2 cytokines between TPE and MPE. Pooled data based on a random-effects model or fixed-effects model and standardized mean differences (SMDs) across studies were used to compare TPE and MPE. We also performed Egger's test to assess publication bias. Of 917 identified studies, a total of 42 studies were selected for the meta-analysis. Compared with MPE subjects, TPE subjects had a significantly higher level of TNF-α [2.22, (1.60-2.84)], an elevated level of IFN-γ [3.30, (2.57-4.40)] in pleural effusion, a situation where the Th1 immune response dominated. Conversely, the levels of interleukin-4 (IL-4) and IL-10 (Th2 cytokines) were higher in the MPE subjects than in the TPE subjects, showing statistically nonsignificant tiny effects [-0.15, (-0.94 to 0.63) and -0.04, (-0.21 to 0.12), respectively]. We confirmed that TPE, a situation in which the Th1 cytokines are predominant. The slight preponderance of Th2 cytokines in MPE, which is not convincing enough to prove.

Comparison of clinical and imaging features between pulmonary tuberculosis complicated with lung cancer and simple pulmonary tuberculosis: a systematic review and meta-analysis.
This review aimed to compare the clinical features and CT imaging features between patients with pulmonary tuberculosis (PTB) and lung cancer and patients with PTB alone. That would help to analyse the differences between the two and consequently providing a theoretical basis for the clinical diagnosis and treatment for the patients. Relevant case-control studies focusing on the clinical and CT imaging characteristics between PTB with lung cancer and PTB alone were systematically searched from five electronic databases. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for comparison. As of 2021-07-06, a total of 1735 articles were retrieved. But only 15 articles were finally included for meta-analysis. The results showed a higher proportion of irritable cough, haemorrhagic pleural effusion and lower proportion of night sweating in PTB patients with lung cancer than in PTB patients, and the differences were statistically significant (irritable cough: OR 2.43, 95% CI 1.43-4.11; haemorrhagic pleural effusion: OR 5.73, 95% CI 1.63-20.12; night sweating: OR 0.56, 95% CI 0.36-0.87). In addition, there are many differences in the imaging characteristics of the two types of patients. In conclusion, this review summarises the similarities and differences in clinical symptoms and imaging features between patients with PTB and lung cancer and patients with PTB alone, suggesting that we should be alert to the occurrence of lung cancer in patients with obsolete PTB relapse.
