Background: Simian virus 40 (SV40), a polyomavirus, was discovered as a contaminant of a human polio vaccine in the 1960s. It is known that malignant mesothelioma (MM) is associated with SV40, and that the virus works as a cofactor to the carcinogenetic effects of asbestos. However, the reports about the correlation between SV40 and MM have not been consistent. The purpose of this study is to identify SV40 in MM tissue in Korea through detection of SV40 protein and DNA.
Methods: We analyzed 62 cases of available paraffin-blocks enrolled through the Korean Malignant Mesothelioma Surveillance System and performed immunohistochemistry for SV40 protein and real-time polymerase chain reaction (PCR) for SV40 DNA.
Results: Of 62 total cases, 40 had disease involving the pleura (64.5%), and 29 (46.8%) were found to be of the epithelioid subtype. Immunostaining demonstrated that all examined tissues were negative for SV40 protein. Sufficient DNA was extracted for real-time PCR analysis from 36 cases. Quantitative PCR of these samples showed no increase in SV40 transcript compared to the negative controls.
Conclusions: SV40 is not associated with the development of MM in Korea.

Malignant Mesothelioma is a malignant tumor arising from the peritoneum, pleura or pericardium. It's rarely reported in dogs. Currently, there are two classifications of neoplasia: one for human medicine and other for veterinary.

Thoracic malignancies (lung cancers and malignant pleural mesothelioma) are prevalent worldwide and are associated with high morbidity and mortality. Effective treatments are needed for patients with advanced disease. Cell therapies are a promising approach to the treatment of advanced cancers that make use of immune effector cells that have the ability to mediate antitumor immune responses.

Mesothelioma is a lethal cancer of the serosal lining of the body cavities. Risk factors include environmental and genetic factors. Asbestos exposure is considered the principal environmental risk factor, but other carcinogenic mineral fibers, such as erionite, also have a causal role.

Primary pericardial mesothelioma is a highly aggressive and rare neoplasm that arises from the pericardial mesothelial cell and has a poor prognosis. The diagnosis is usually established by histological and immunohistochemical studies. Malignant mesothelioma most frequently occurs from the pleura (90%), less frequently from the peritoneum and pericardium (6%-10%), and very rarely from the tunica vaginalis in the testis.

Background: In malignant pleural mesothelioma), it is difficult to evaluate the degree of tumor progression using imaging findings. It is essential to develop an objective index that is independent of imaging findings and useful for assessing the degree of tumor progression and indications for surgery.
Methods: We retrospectively evaluated the data of 79 patients with malignant pleural mesothelioma who underwent extrapleural pneumonectomy or pleurectomy/decortication at our institution between 1999 and 2022.
