Analysis of TERT mRNA Levels and Clinicopathological Features in Patients with Peritoneal Mesothelioma.
Cancers (Basel)
January 2025
Department of Medicine and Surgery, LUM University, Casamassima, 70010 Bari, Italy.
Background/objectives: Telomerase reverse transcriptase (TERT) is the catalytic subunit of the telomerase enzyme responsible for telomere length maintenance and is an important cancer hallmark. Our study aimed to clarify the mRNA expression of TERT in peritoneal mesothelioma (PeM), and to explore the relationship between its expression and the clinicopathological parameters and prognosis of patients with PeM.
Methods: In a cohort of 13 MpeM patients, we evaluated histotype, nuclear grade, mitotic count, necrosis, inflammation, Ki67, BAP1, MTAP and p16 expression by immunohistochemistry, / status by FISH and TERT mRNA expression by RNAscope.
Cytoreductive surgery in diffuse pleural mesothelioma. What have we learnt from MARS2, EORTC-L1205 and other recent studies?
Eur J Surg Oncol
January 2025
Department of Surgery, Clinique de Genolier, Genolier, Switzerland. Electronic address:
Cytoreductive surgery remains controversial in pleural mesothelioma. The MARS2 trial suggested that extended pleurectomy decortication following neoadjuvant chemotherapy was associated with no survival benefit, more serious adverse events and poorer quality of life than systemic chemotherapy alone in patients with resectable pleural mesothelioma. However, patient selection, chemotherapy scheme, high surgical mortality (9 %) and poor outcomes in the surgical cohort have been raised by mesothelioma experts as potential issues in MARS2.

Ann Surg Oncol
January 2025
Department of Surgery, Johns Hopkins University School of Medicine, Baltimore, MD, USA.
Background: Hematologic changes after splenectomy and hyperthermic intraperitoneal chemotherapy (HIPEC) can complicate postoperative assessment of infection. This study aimed to develop a machine-learning model to predict postoperative infection after cytoreductive surgery (CRS) and HIPEC with splenectomy.
Methods: The study enrolled patients in the national TriNetX database and at the Johns Hopkins Hospital (JHH) who underwent splenectomy during CRS/HIPEC from 2010 to 2024.
Pleural Rosai-Dorfman disease complicated with renal clear cell carcinoma: a case report and literature review.
Front Oncol
January 2025
Department of Radiology, Daping Hospital, Army Medical University, Chongqing, China.
Background: Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare non-malignant disorder characterized by excessive proliferation of histiocytes, the cause of which remains unknown. Although the lymph nodes are the most commonly affected site, some patients may present with extranodal involvement, particularly in the skin, nasal cavity, eyes, and bones. In this report, we aim to present a unique case of RDD with pleural involvement in a 61-year-old patient.

Photochem Photobiol
January 2025
Department of Radiation Oncology, University of Pennsylvania, Philadelphia, Pennsylvania, USA.
Photodynamic therapy (PDT) has shown promise as an adjuvant treatment for malignant pleural mesothelioma when combined with surgical resection. Accurate light dosimetry is critical for treatment efficacy. This study presents an improved method for analyzing light fluence distribution in pleural PDT using a standardized anatomical coordinate system and advanced computational modeling.
