Glioblastoma Treatment Breakthrough: Electric Fields Plus Immunotherapy Shows Promise

Los Angeles, CA – A Groundbreaking Study Led By Keck Medicine Of Usc Researchers Reveals A Potential New Weapon Against Glioblastoma, An Aggressive brain Tumor With Limited Treatment Options. The Research Suggests That Combining Tumor Treating Fields (Ttfields) Therapy With Immunotherapy And Chemotherapy Considerably Extends Survival, Especially For Patients With Inoperable Tumors.

Electric fields: A Novel Approach to Fighting Brain Tumors

Ttfields Therapy Involves Delivering Low-Intensity, Alternating Electric Fields directly To The Tumor Site. These electric Fields Disrupt Cancer Cell Division And Growth, While Also Stimulating The Body’s Immune system To Target The Malignant Cells. when Used For Glioblastoma, Electrodes are Placed On The Scalp To Deliver Precisely Focused Fields To The Tumor, Typically For About 18 Hours Daily.

Researchers Found That Ttfields Attract Tumor-Fighting T Cells To The Glioblastoma. Following Up With Immunotherapy Keeps These T Cells Active longer And Recruits Even More Potent Immune Cells.

Did You Know? Glioblastoma is one of the most common and aggressive types of brain cancer, accounting for about 15% of all brain tumors.

Immunotherapy Boost: Unlocking the Body’s Defenses

Dr. david Tran, Chief Of Neuro-Oncology With Keck Medicine, States That Ttfields Can “Prime The Body” For An Effective Immune Response. This is Crucial Because Glioblastomas Are Often Shielded From The Immune System By The Blood-Brain Barrier.

The Combination of Ttfields And Immunotherapy Creates A Powerful “In Situ Immunization” Effect Within The Tumor, Allowing Immune Checkpoint Inhibitors (Icis) Like Pembrolizumab To Work More Effectively. Pembrolizumab Enhances The Ability Of T Cells To Identify And Destroy Cancer Cells.

“Think Of It Like A Team Sport — Immunotherapy Sends Players In To Attack The Tumor (The Offense), While Ttfields Weaken The Tumor’s Ability To Fight Back (The Defense). And Just Like In Team Sports, The Best Defense is A good Offense,” Said Tran.

Key Findings: Increased Survival Rates

The Study, Which Analyzed Data From The 2-The-Top Phase 2 Clinical Trial, Showed That Adding Immunotherapy To Ttfields And Chemotherapy Was Associated With A 70% Increase In Overall Survival. Patients With Larger, Unresected Tumors Experienced An Even More Significant Benefit.

Patients Using The Combined Therapy Lived Approximately 10 Months Longer Then Those Who Used Ttfields With Chemotherapy Alone. For Those With Inoperable Tumors, The Survival Increase Was Approximately 13 Months.

The Implication Is That A Larger Tumor Mass May Provide more Targets For The Therapy To Act Against, Sparking A Stronger Immune Response.

Understanding Tumor Treating Fields (TTFields)

At the heart of this advancement lies a technology known as Tumor Treating fields (TTFields). This innovative approach uses precisely tuned, low-intensity, alternating electric fields delivered to the tumor site. The mechanism of action is multifaceted. By disrupting the rapid division of cancer cells, TTFields can inhibit tumor growth and trigger programmed cell death (apoptosis). This method offers a targeted approach, differing significantly from traditional treatments like chemotherapy and radiation therapy.

How TTFields Work: The Science Behind the Technology

TTFields work by interfering with the formation of the mitotic spindle, a crucial cellular structure needed for cell replication. Cancer cells, which divide uncontrollably, are particularly vulnerable to this disruption. The electric fields also trigger an immune response by increasing the expression of specific antigens on the surface of cancer cells, making them more susceptible to attack by the patient’s own immune system. This dual action makes TTFields a potentially potent weapon in the fight against malignant brain tumors.

• Disruption of Cell Division: Preventing cancer cell replication.
• Immune System Activation: Enhancing the immune response to target tumors.
• Targeted Therapy: Affecting only the tumor and surrounding area.

TTFields in Action: Treatment and Results

The application of TTFields typically involves a non-invasive device that patients wear on their heads. The device generates electric fields that are directed at the tumor. The system is designed for continuous use, often for 18 hours a day, which may seem unusual on a first look.

Glioblastoma Multiforme (GBM) and TTFields: Clinical Trials and Patient Outcomes

One of the most important advancements has been in the treatment of glioblastoma multiforme (GBM),the most common and aggressive form of brain cancer. clinical trials have shown that combining TTFields with chemotherapy (specifically temozolomide) can significantly improve overall survival and progression-free survival in patients with newly diagnosed GBM.This has opened doors for a new era in the treatment of GBM survival. The results are promising compared to the previous standards of care.
