Malignant pleural mesothelioma (MPM) is a pleura-derived malignant tumor, with a gradually increasing incidence in recent years based on domestic and foreign epidemiologic data. Most patients with MPM are diagnosed at an advanced stage due to its insidiousness and aggressiveness. The therapeutic strategies of MPM mainly include surgery, chemotherapy and radiotherapy. Recently, the immunotherapy has altered the treatment pattern and further improved the survival of these patients. In order to timely present the domestic and foreign progress in the diagnosis and treatment of MPM, and to further improve the level of standardized diagnosis and treatment in MPM in China, this guideline was formulated on the basis of existing clinical research evidence combined with experts' opinions. The guideline covers the epidemiology, diagnosis, pathology, treatment and follow-up of MPM.

Patients with malignant pleural mesothelioma (MPM) usually present with poor prognosis and short survival period, and there has been a lack of effective treatment options for a long time. Chemotherapy has limited improvement in the clinical outcome of advanced patients (the median survival is less than one year), and it is difficult to find suitable targets for targeted therapy. Recent in-depth research on immunotherapy has changed the treatment pattern of MPM. Especially, the dual immunotherapy regimen significantly improved the survival outcome of patients across subgroups and prolonged the survival time of MPM patients. Therefore, it has been approved for unresectable MPM as first-line treatment for patients. The exploration of other mono or combo immunotherapy regimens in the first and second-line settings of MPM is also underway. How to identify the best beneficial population of each regimen through predictive biomarkers is also a hot spot for researchers. This article will focus on the most up-to-date progress of MPM epidemiology, histological characteristics, pathogenesis, treatment patterns and the advances of immunotherapy in the disease.

Lung cancer is the most commonly diagnosed cancer worldwide. Malignant pleural effusion (MPE) caused by advanced lung cancer seriously affect the patients' quality of life and prognosis. The management of MPE includes thoracentesis, pleurodesis, indwelling pleural catheters and drug perfusion in pleural cavity. Vascular endothelial growth factor (VEGF) and its receptor are a group of important ligands and receptors that affect angiogenesis. They are the main factors controlling angiogenesis, and they play an important role in the formation of MPE. Bevacizumab is a recombinant humanized VEGF monoclonal antibody, competitively binding to endogenous VEGF receptor. Bevacizumab can inhibit new blood vessel formation, reduce vascular permeability, prevent pleural effusion accumulation and slow the growth of cancers. This review aims to discuss the progress of bevacizumab in the treatment of MPE caused by non-small cell lung cancer (NSCLC), and explore the clinical application, efficacy, safety and future direction of bevacizumab.

PURPOSE: The purpose of this study was to evaluate the efficacy of intrapleural chemotherapy (IPC) with cisplatin and cytarabine in the management of malignant pleural effusion (MPE) from non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS: A prospective analysis was carried out on 40 patients with pathologically proven MPE from NSCLC who had received IPC. A single dose of cisplatin 100 mg/m2 plus cytarabine 1200 mg/m2 in 250 ml normal saline was instilled into the pleural space via a chest tube and drained 4 hours later. Patients were evaluated for toxicities and responses at 1, 2, & 3 weeks and then at monthly intervals if possible. Systemic chemotherapy was administered, if the patient agreed to receive it, after achieving complete control (CC) of MPE. RESULTS: The median duration of chest tube insertion for drainage was 7 (3~32) days. Among the assessable 37 patients, CC and partial control (PC) were 32 (86.5%) and 4 (10.8%) patients, respectively (overall response rate 97.3%). The median duration of response was 12 months (2~23) and there were only two relapses of IPC after achieving CC. Among the 35 patients who were assessable until they died, 28 patients (80.0%) maintained CC until the last follow-up. There was only one toxic death and the toxicities of IPC, versus the results obtained, were deemed acceptable. CONCLUSION: The procedures were tolerable to the patients and chemotherapy-induced complications were at an acceptable level. The outcome of this trial indicates that IPC has a superior and long lasting treatment response in the management of patients with MPE from NSCLC.

BACKGROUND: Maligant pleural effusions are common and significant problems in patient with advanced malignancies. In comparison with traditional sclerosing agent, intrapleural chemotherapy has a potential advantage of treating the underlying malignancy in addition to providing local control of th effusion. This study evaluated efficacy of intrapleural chemotherapy with cisplatin and cytarabine in the management of malignant pleural effusion from lung cancer and others. METHODS: 29 patients with pathology-proven malignant pleural effusion were prospectively analyzed to estimate the effect of intrapleural chemotherapy. A single dose of cisplatin 100mg/m plus cytarabine 1200mg/m in the 250ml normal saline were instilled into the pleural space via a chest tube and drained 4 hours later. Patients were evaluated for toxicity and response at 24hours, 1st, 2nd, 3rd week, and monthly interval. No recurrence of the effusion was considered a complete response(CR). Partial responses (PR) was defined as a 75% or greater decrease in the amount of effusion on serial chest radiographs. RESULTS: The overall response rate(CR plus PR) was 93.1% (27 of 29 patients). The median length of response was 7.5 months. Among 17 patients who were assessable until they died, 14 patients(82%) maintained complete response at the last follow-up. One patient experienced reversible grade 4 myelosuppression, 3 patients had grade 3 nausea & vomiting. 2 patients had empyema, and 2 patients had wound infection. CONCLUSIONS: The outcome of this trial indicated that the intrapleural chemotherapy with cisplatin and cytarabine with little treatment related mortality and morbidity.

BACKGROUND: Thyroid function abnormality (TFA) is one of the common adverse reactions in patients with advanced non-small cell lung cancer (NSCLC) treated with immunotherapy, but the risk factors of TFA and its relationship with efficacy are not completely clear. The purpose of this study was to explore the risk factors of TFA and its relationship with efficacy in patients with advanced NSCLC after immunotherapy. METHODS: The general clinical data of 200 patients with advanced NSCLC in The First Affiliated Hospital of Zhengzhou University from July 1, 2019 to June 31, 2021 were collected and analyzed retrospectively. χ² test and multivariate Logistic regression were used to explore the risk factors of TFA. Kaplan-Meier curve was drawn and Log-rank test was used for comparison between groups. Univariate and multivariate Cox analysis was used to explore the efficacy factors. RESULTS: A total of 86 (43.0%) patients developed TFA. Logistic regression analysis showed that Eastern Cooperative Oncology Group Performance Status (ECOG PS), pleural effusion and lactic dehydrogenase (LDH) were factors influencing TFA (P<0.05). Compared with normal thyroid function group, the median progression-free survival (PFS) of patients in the TFA group was significantly longer (19.0 months vs 6.3 months, P<0.001), and the objective response rate (ORR) (65.1% vs 28.9%, P=0.020) and disease control rate (DCR) (100.0% vs 92.1%, P=0.020) of the TFA group were better than those of the normal thyroid function group. Cox regression analysis showed that ECOG PS, LDH, cytokeratin 19 fragment (CYFRA21-1) and TFA were factors influencing prognosis (P<0.05). CONCLUSIONS ECOG PS, pleural effusion and LDH may be risk factors affecting the occurrence of TFA and TFA may be a predictor of the efficacy of immunotherapy. Patients with advanced NSCLC who have TFA after immunotherapy may obtain better efficacy.

Malignant mesothelioma is a highly malignant disease that most often occurs in the pleural cavity, followed by the peritoneum and pericardium. Malignant peritoneal mesothelioma (MPM) accounts for 10%-15% of all mesothelioma. The most important risk factor for MPM is exposure to asbestos. MPM has no specific clinical symptoms, imaging and histopathology are critical for the diagnosis. There are currently no generally accepted guidelines for curative treatment of MPM. The patient mainly presented with abdominal pain, abdominal distension and discomfort. Due to extensive omentum metastasis, no further surgical treatment was performed. Pemetrexed combined with cisplatin chemotherapy was given for 2 cycles, and the patient is still alive.

Pleuropulmonary blastoma (PPB) is a rare intrathoracic neoplasm, found solely in childhood. The usual symptoms are dyspnea, chest discomfort, recurrent respiratory infections, fever, dry cough, and chest pain. The progress of PPB is usually aggressive and its progress is generally poor. Lymphatic spread to the hilar and mediastinal nodes can occur. Distant metastasis is found in brain, bones, and intra-abdominal organs. Surgical resection is the treatment of choice. When the disease is too extensive for surgical resection, neoadjuvant chemotherapy can be used. We report 2 cases of pleuropulmonary blastoma in children successfully treated with multimodal therapy.
