University of Maryland School of Medicine Thoracic Surgeons Identify Lymph Nodes That May Help to Determine Prognosis for Patients with Pleural Mesothelioma

Finding Cancer in These Nodes Doubles Risk of Recurrence and Death, New Research Shows

University of Maryland School of Medicine (UMSOM) surgeons have identified a group of lymph nodes in the chest that appear highly significant in predicting the prognosis for patients with malignant pleural mesothelioma – a deadly cancer of the chest lining that is usually caused by asbestos.

The researchers found that presence of cancer in these lymph nodes increased the risk of recurrence or death more than two-fold in patients undergoing surgery for mesosthelioma, according to new research presented this week at the Society of Thoracic Surgeons (STS) annual meeting.

In seven percent of the patients in the study, the posterior intercostal lymph nodes – a part of the body’s lymphatic system that drain the spaces between the ribs – were the only nodes that showed evidence the cancer had spread, or metastasized. They are not normally considered in staging the cancer or removed during surgery.

“These nodes warrant further investigation, including non-operative techniques to identify them and factor them into treatment decision-making,” says Joseph S. Friedberg, MD, the Charles Reid Edwards Professor of Surgery and Head of the Division of Thoracic Surgery at UMSOM. Dr. Friedberg is also Thoracic Surgeon-in-Chief of the University of Maryland Medical System (UMMS).

“Although larger studies are needed, we believe that these lymph nodes should routinely be removed during any surgery with therapeutic intent for malignant pleural mesothelioma, especially as they may be the only lymph nodes to harbor metastatic disease,” says Dr. Friedberg, who also is the director of the Mesothelioma and Thoracic Oncology Treatment and Research Center at UMSOM. The center is part of the University of Maryland Greenebaum Comprehensive Cancer Center (UMGCCC).

This is the first study to assess the importance of this group of lymph nodes on survival in malignant plural mesothelioma (MPM) patients who undergo surgery. Lymph nodes play a critical role in how oncologists stage cancers and determine prognosis and treatment.

MPM is an incurable cancer, most commonly caused by exposure to asbestos. Patients treated with chemotherapy alone, the standard of care, typically live only 12 to 18 months. In the United States, 2,000 to 3,000 patients are diagnosed with MPM each year.

Dr. Friedberg has pioneered the use of lung-sparing surgery to treat MPM and has published research that showed that patients who had this surgery, plus photodynamic therapy and chemotherapy, had a median survival of nearly three years, with a subset of patients living longer than seven years.

In this study, Dr. Friedberg and his colleagues removed the posterior intercostal lymph nodes in 56 patients who took part in a lung-sparing surgery clinical trial. Forty-eight percent of the patients were found to have cancer in these nodes, including the seven percent who had no cancer in any other lymph nodes. After adjusting for multiple variables, “intercostal nodes remained associated with a 2.5-fold elevated risk of progression and a 2.3-fold elevated risk of death,” the research team concluded.

“Malignant pleural mesothelioma is a very difficult cancer to treat, and Dr. Friedberg’s research advances our ability to understand how we might incorporate these newly-identified lymph nodes into better staging and treatment for our patients,” says UMSOM Dean E. Albert Reece, MD, PhD, MBA, University Executive Vice President for Medical Affairs and the John Z. and Akiko K. Bowers Distinguished Professor.
