Insights

Pleural mesothelioma (PM) treatments are advancing beyond chemotherapy. While dual immune checkpoint blockade shows promise, new therapies like antibody-drug conjugates and cell-based treatments are under investigation for better outcomes in this aggressive cancer.

Area of Science:

  • Oncology
  • Immunotherapy
  • Malignant Mesothelioma Research

Background:

  • Pleural mesothelioma (PM) is an aggressive cancer with limited treatment options and poor prognosis.
  • Platinum-based chemotherapy has been the long-standing standard of care.
  • Despite genomic discoveries, targeted therapies for PM are not yet in clinical practice.

Purpose of the Study:

  • To review recent advancements in understanding PM biology.
  • To evaluate current phase I-III clinical trials for PM treatment.
  • To highlight promising future therapeutic candidates for PM.

Main Methods:

  • Review of recent scientific literature on PM biology.
  • Analysis of ongoing and completed phase I-III clinical trials in PM.
  • Identification and discussion of novel therapeutic modalities under investigation.

Main Results:

  • Dual immune checkpoint blockade (ICB) with nivolumab plus ipilimumab represents a recent advance, but durable responses are infrequent.
  • Many patients do not respond to current ICB therapies.
  • Numerous novel treatment strategies are in clinical trials, including antibody-drug conjugates, bi-specific antibodies, CAR T-cells, vaccines, and oncolytic viruses.

Conclusions:

  • Significant progress is being made in understanding PM biology and developing novel therapies.
  • While ICB has improved treatment, further research is crucial for more effective and durable responses.
  • Ongoing clinical trials offer hope for improved therapeutic options for pleural mesothelioma patients.

Pleural Disorders: Types and Brief Description

The pleura is a vital part of the respiratory system. It's a double-layered membrane surrounding the lungs and lining the chest cavity. The two layers of the pleura are:

Pleural Effusion II: Symptoms and Management

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Pneumothorax-II01:27

Pneumothorax-II

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Pleura of the Lungs01:13

Pleura of the Lungs

The lungs are nestled in a cavity, shielded by the pleura. The pleura, a form of serous membrane, wraps around each lung. This membrane arrangement consists of two layers: the visceral and parietal pleurae. The visceral pleura lines the surface of the lungIn contrast, the parietal pleura is the outer layer and contacts to the thoracic wall, the mediastinum, and the diaphragm. The hilum is the point of connection between the visceral and parietal layers. The space between the parietal and...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
