• Risk factors, prognostic factors, and nomograms for distant metastasis in patients with malignant pleural mesothelioma: A population-based retrospective study. Q. Lu, C. Liu, M. Xu, et al. 2025;53(10):3000605251389356. PubMed · Publisher · Free full text

  Abstract

  ObjectivesMalignant pleural mesothelioma is a rare and aggressive thoracic tumor with a poor prognosis, wherein distant metastasis is associated with the lowest survival rates. It is imperative and emergent to construct nomograms based on risk factors and prognostic factors for distant metastasis in patients with malignant pleural mesothelioma.MethodsWe extracted data for the duration between 2010 and 2015 from the Surveillance, Epidemiology, and End Results (SEER) database and randomly categorized the patients into the training (70%) and validation (30%) cohorts. Risk factors for distant metastasis in patients with malignant pleural mesothelioma were identified using univariate and multivariate logistic regression analyses, and prognostic factors for patients with distant metastasis were determined using univariate and multivariate Cox regression analyses. Two nomograms were established based on the training cohort and evaluated using the validation cohort. The C-index, receiver operating characteristic curve, calibration curve, and decision curve analysis were used to assess the performance of the two nomograms.ResultsIn total, 2056 primary malignant pleural mesothelioma patients were included, and 341 patients were initially diagnosed with metastatic malignant pleural mesothelioma. Histology, laterality, grade, tumor stage, and node stage were independent risk factors for distant metastasis in patients with malignant pleural mesothelioma. Chemotherapy and metastasis to the lung, bone, and brain were independent prognostic factors for patients with malignant pleural mesothelioma and distant metastasis. The C-index values of the risk nomogram in the training and validation cohorts were 0.723 and 0.782, respectively. The C-index values of the prognostic nomogram in the training and validation cohorts were 0.678 and 0.712, respectively. The receiver operating characteristic curves, calibration curves, and decision curve analysis also demonstrated good predictive performance for the two nomograms in the training and validation cohorts.ConclusionsNomograms are useful and reliable tools for predicting distant metastatic risk in patients with malignant pleural mesothelioma and overall survival in patients with malignant pleural mesothelioma who had distant metastasis. These nomograms can provide strong references to clinicians to facilitate clinical decisions.

• Case report: targeted therapy of malignant pleural mesothelioma with anaplastic lymphoma kinase receptor tyrosine kinase gene fusion mutation by crizotinib. Y. Wu, Y. Zhao, L. Yu, et al. 2024;52(11):3000605241287320. Case report PubMed · Publisher · Free full text

  Abstract

  Malignant mesothelioma is a rare highly invasive tumour originating from the mesothelial cells of the pleura, peritoneum and pericardium. Malignant pleural mesothelioma (MPM) is the most common type in all malignant mesothelioma. The onset of MPM is associated with exposure to asbestos and it can have an incubation period of up to 40 years. The incidence of MPM has been increasing worldwide in recent years, so more attention has been focused on its diagnosis, treatment and prognosis. Activating mutations, amplifications and fusions/rearrangements of the anaplastic lymphoma kinase receptor tyrosine kinase (ALK) gene are commonly seen in patients with non-small cell lung cancer. However, it is rare in MPM. This current case report describes a female patient with advanced MPM with an ALK gene fusion mutation. In this particular case, treatment with crizotinib demonstrated some initial efficacy, which suggests that this might be a promising strategy for patients with advanced MPM with an ALK gene mutation. This required further research and evaluation in the future.

• Peritoneal well-differentiated papillary mesothelioma associated with infertility in a 37-year-old woman. B. Pang, C. Hu, Q. Liu, et al. 2021;49(1):300060520986680. Case report PubMed · Publisher · Free full text

  Abstract

  Well-differentiated papillary mesothelioma (WDPM) is an uncommon mesothelial tumor. The lesions may be single or multiple and usually behave in a benign or indolent fashion, sometimes persisting for many years. In the present case, a 37-year-old woman had experienced primary infertility for 12 years, and a diagnostic laparoscopy was performed. Approximately 200 mL of dark red, free fluid in the pelvis and more than 10 yellow-white nodules on the surface of the right round ligament, sacrum ligament, right fallopian tube, and both sides of the uterus were found. A lesionectomy was performed and immunohistochemical markers indicated WDPM with adenomatoid tumor. The patient was monitored by computed tomography and serum CA125 (cancer antigen 125) levels for 49 months with no recurrence. WDPM and adenomatoid tumor are both benign tumors of mesothelial origin. Because of the lack of effective radical treatment, regular follow-up is sufficient. However, the effects of estrogen and progesterone on WDPM and adenomatoid tumors during ovulation or pregnancy remains unclear. Although WDPM is not life threatening, a strategy to fulfill the fertility requirements of women with this condition is a new challenge for infertility doctors.

• Right diaphragm metastasis of endometrial cancer: a case report. T. Zhang, X. Li, G. Liu, et al. 2020;48(10):300060520961706. Case report PubMed · Publisher · Free full text

  Abstract

  A diaphragmatic tumor is usually caused by metastasis from lung cancer, malignant mesothelioma, and malignant thymoma. Endometrial cancer is rarely involved in metastasis to the diaphragm. A right anterior mediastinal tumor was found in a 60-year-old woman who was initially diagnosed with endometrial carcinoma. There was initially no relationship between the right anterior mediastinal tumor and endometrial carcinoma. Radical curative surgery was performed for endometrial carcinoma. The endometrial carcinoma stage was IA. The patient was admitted to the Department of Thoracic Surgery 6 months after the curative surgery. Intraoperative exploration showed a tumor growing in the right diaphragm. Right diaphragmotomy was performed. Immunohistochemistry showed metastasis of endometrial carcinoma to the diaphragm. Endometrial cancer solitary metastasis to the diaphragm is rare. Clinicians should be aware of this possibility. Surgical treatment followed by a pathological examination is the most useful method for determining the diagnosis of a diaphragmatic tumor due to metastasis of endometrial cancer.

• Resection of mesothelial cyst of uterine round ligament by laparoscopic transabdominal preperitoneal procedure alone or combined with open surgery. D. Chen, P. Zhang, H. Zhang, et al. 2019;47(11):5475-5482. PubMed · Publisher · Free full text

  Abstract

  Objective: Surgical treatment of a mesothelial cyst of the uterine round ligament (MCURL), an uncommon entity, has been rarely documented. In this article, we present our experience with excision of MCURLs.

  Methods: The records of all female patients undergoing surgical removal of a groin mass in our department from March 2013 to November 2018 were retrospectively reviewed. Demographic information, clinical data, and follow-up outcomes were collected and analyzed.

  Results: Among 298 women who underwent groin hernia repair, 17 (5.7%) had MCURLs. Of these 17 patients, 13 were aged 30 to 45 years and 15 had a normal body mass index (18.5–23.9 kg/m2). MCURLs occurred predominantly on the right side (11/17). Approximately half of the patients (9/17) were preoperatively misdiagnosed with inguinal hernias. Approximately 70% (12/17) of the lesions were localized medially to the inner ring of the inguinal canal and excised by a laparoscopic transabdominal preperitoneal (TAPP) procedure alone. Five patients required open surgery following the TAPP procedure because the cyst extended distally beyond the inner ring. No recurrence was noted during the entire follow-up period.

  Conclusion: Most MCURLs were localized medially to the inner ring of the inguinal canal and could be excised by a TAPP procedure.

• Successful one-lung ventilation by blocking the right intermediate bronchus in a 7-year-old child: a case report. S.Y. Baek, J.H. Kim, G. Kim, et al. 2019;47(6):2740-2745. Case report PubMed · Publisher · Free full text

  Abstract

  A 7-year-old child underwent surgical excision of a benign mesothelioma of the pleura near the right lower lung. Although insertion of a wire-reinforced endotracheal tube through the left main bronchus was attempted for one-lung ventilation to secure the surgical field of view, the attempt failed. Therefore, an endotracheal tube was inserted into the trachea, and an Arndt endobronchial blocker (Cook Medical, Bloomington, IN, USA) was placed in the right intermediate bronchus under bronchoscopic guidance to selectively block the right lower and middle lobes. The surgery was performed while ventilating the right upper lobe and left lung, and no specific intraoperative adverse events occurred.

• The value of inflammatory parameters in the prognosis of malignant mesothelioma. O. Abakay, A.C. Tanrikulu, Y. Palanci, et al. 2014;42(2):554-65. PubMed · Publisher

  Abstract

  Objective: This study investigated the relationship between potential prognostic parameters that may be associated with increased inflammation and survival in patients with malignant mesothelioma (MM).

  Methods: This retrospective study assessed potential prognostic parameters measured at the time of MM diagnosis. Data on asbestos exposure, histopathological subtype of MM and laboratory parameters were collected.

  Results: In 155 patients with MM (90 male), mean survival time was 13.9 months. In univariate analysis, age ≥ 60 years and neutrophil-to-lymphocyte ratio (NLR) ≥ 3 were associated with significantly shortened median survival times. In multivariate analysis, nonepithelial subtype, red cell distribution width (RDW) ≥ 20% and NLR ≥ 3 were associated with significantly shortened median survival times. Mortality rate was increased 2.77-, 1.67- and 1.52-fold in patients with RDW ≥ 20%, NLR ≥ 3 and nonepithelial subtype, respectively. Nonepithelial subtype, white blood cell count ≥ 11 200 µl and platelet-to-lymphocyte ratio ≥ 300 at baseline were associated with a heightened NLR value.

  Conclusions: The NLR and RDW were significant predictive factors for MM prognosis.

• The diagnostic utility of maspin in the distinction between malignant mesothelioma and pulmonary adenocarcinoma. E.U. Akyildiz, B. Oz, I. Sehitoglu, et al. 2010;38(3):1070-6. PubMed · Publisher

  Abstract

  Immunohistochemistry is frequently employed to differentiate between malignant mesothelioma (MM) and pulmonary adenocarcinoma (AC) infiltrating the pleura, but there is uncertainty as to which antibodies are most useful. The present study investigated the presence of the serine protease, maspin, in epithelioid MMs and evaluated the diagnostic utility of maspin for the differential diagnosis between epithelioid MM and pulmonary AC with pleural involvement. The results showed more frequent maspin immunostaining among AC cases compared with MM cases. Maspin positivity was significantly higher among AC cases with respect to both the extent and intensity of staining. A significant difference also existed between the two tumour types with respect to the overall maspin score. Despite these findings, the sensitivity and specificity of maspin positivity to detect AC were only 59% and 73%, respectively, indicating that detection of maspin is of no value for the differential diagnosis of AC and MM.
