Recurrence, Clinical Trials, and Advanced Care

At a Glance

When glioblastoma returns, treatment focuses on maintaining quality of life and managing symptoms through salvage surgery, re-irradiation, or targeted drugs like Bevacizumab. Clinical trials offer access to new therapies, and early palliative care helps manage symptoms effectively.

Facing a recurrence—the return of the tumor—is a heavy and difficult moment in the glioblastoma journey. It is important to know that while the “standard” path of surgery and radiation may have already been used, there is still a wide range of salvage options available to manage the disease and maintain your quality of life.

Understanding the KPS Score

When considering treatments for a recurrence, doctors heavily rely on your Karnofsky Performance Status (KPS). This is a 0-100 scale that measures your ability to carry out normal daily activities and your level of independence. A score of 100 means normal functioning with no evidence of disease, while scores below 70 indicate a need for assistance with self-care [1]. A higher KPS score often makes a patient eligible for more aggressive treatments and clinical trials.

Surgical and Radiation Options

If the recurrence is localized to one area and your KPS is strong, your medical team may recommend repeating the treatments used initially:

  • Salvage Surgery (Re-operation): In selected patients, a second surgery to remove the recurring tumor can significantly prolong survival and relieve symptoms caused by pressure in the brain [2][3]. The goal remains the complete resection of enhancing tumor (CRET) while preserving brain function [4].
  • Re-irradiation: Advances in technology have made it possible to safely deliver radiation to the same area more than once. This can be done through localized stereotactic radiosurgery (SRS) or shorter, fractionated courses of radiation [5][6].

Systemic Therapies

When surgery or radiation is not the best fit, doctors turn to second-line medications.

  • Bevacizumab (Avastin®): This is one of the most commonly used drugs for recurrence. It works by “starving” the tumor of its blood supply [7].
    • The Benefit: Bevacizumab is highly effective at reducing brain swelling and the need for steroids, which significantly improves progression-free survival (the time you live without the tumor getting worse or causing symptoms) [8][9].
    • The Caveat: While it helps patients feel better and stay stable longer, studies have shown it does not consistently extend overall survival (the total length of time a patient lives) [9][10].
    • Side Effects: Patients taking bevacizumab should monitor for side effects such as high blood pressure, increased risk of bleeding, and issues with wound healing.
  • Regorafenib: This is a newer targeted therapy that may be offered to patients who have already tried bevacizumab or standard chemotherapy. It has shown promise in improving overall survival in some clinical trials, regardless of whether the tumor is MGMT-methylated or not [11][12].

The Critical Role of Clinical Trials

Because standard treatments for recurrence have limitations, clinical trials are often considered the preferred option by experts in neuro-oncology [13]. Trials provide access to cutting-edge therapies that are not yet available to the general public, including:

  • CAR-T Cell Therapy: Training your own immune cells to recognize and attack glioblastoma cells [14][15].
  • Oncolytic Viruses: Using modified viruses to “infect” and kill cancer cells while triggering an immune response [16].
  • Targeted Immunotherapy: New combinations of drugs designed to overcome the tumor’s ability to hide from the immune system [17][18].

Integrating Palliative Care Early

A common misconception is that palliative care is only for the end of life. In reality, palliative care is “supportive care” that should be integrated from the moment of diagnosis or recurrence [19][20].

  • What it does: Palliative care specialists focus on managing the complex symptoms of brain tumors—such as seizures, headaches, and mood changes—and reducing the burden on caregivers [21][22].
  • The impact: Research has shown that glioblastoma patients who receive specialized palliative care often have a higher quality of life and, in some cases, live longer than those who do not [23][24]. It is about living as well as possible, for as long as possible [25].

Common questions in this guide

What treatments are available if my glioblastoma comes back?
When glioblastoma returns, doctors may recommend salvage treatments based on your overall health and the tumor's location. Options can include a second surgery, targeted radiation, medications like bevacizumab or regorafenib, and enrolling in a clinical trial.
What is a KPS score and why does it matter?
The Karnofsky Performance Status (KPS) score measures your ability to perform daily activities and live independently. Doctors use this 0-100 scale to determine if you are healthy enough for certain aggressive treatments or eligible for clinical trials.
How does Bevacizumab (Avastin) help with recurrent glioblastoma?
Bevacizumab works by starving the tumor of its blood supply, which is highly effective at reducing brain swelling and steroid reliance. While it delays symptom progression and helps patients feel better, studies show it does not consistently extend overall survival.
Should I consider a clinical trial for a glioblastoma recurrence?
Because standard treatments for recurrence have limitations, experts in neuro-oncology often recommend clinical trials. These trials provide access to cutting-edge therapies that are not yet widely available, such as CAR-T cell therapy, oncolytic viruses, and targeted immunotherapy.
When should I start palliative care for glioblastoma?
Palliative care, also known as supportive care, should be integrated as early as the moment of diagnosis or recurrence. It focuses on managing complex brain tumor symptoms like seizures and headaches to maximize your quality of life, rather than just being for the end of life.

Questions to Ask Your Doctor

Curated prompts to bring to your next appointment.

  1. 1.Am I a candidate for 'salvage surgery' or re-irradiation based on the location of the recurrence?
  2. 2.How will adding Bevacizumab (Avastin) change my symptoms versus my long-term outlook?
  3. 3.What is my current Karnofsky Performance Status (KPS), and how does that affect my eligibility for clinical trials?
  4. 4.Are there specific trials for 'molecularly targeted' therapies based on my original tumor markers?
  5. 5.Can we consult with the palliative care team now to help manage my symptoms while we pursue active treatment?
