Glioblastoma: An aggressive form of brain tumor
Glioblastoma is classified as WHO grade IV and is considered one of the most aggressive brain tumors. This form of brain tumor develops from astrocytes, a type of glial cell that performs a supportive function in the central nervous system. Glioblastoma is characterized by rapid growth and high invasiveness, which means that it can spread quickly into the surrounding healthy tissue. Due to its aggressive nature, early detection and treatment are crucial to improving the prognosis for those affected. The tumors are often very
heterogeneous, meaning that they can vary in their cell composition. This heterogeneity poses a significant challenge for treatment, as different cells can respond differently to therapies.
Classification and characteristics
Glioblastoma is classified according to the guidelines of the World Health Organization (WHO), which define different grades of tumors. Glioblastomas are classified as grade IV, indicating their high aggressiveness. These tumors are not only fast-growing, but also extremely resistant to conventional treatments. Another characteristic feature is the formation of necrotic areas in the tumor, which are caused by a lack of oxygen and nutrients. These necrotic areas can make diagnosis difficult, as they often cause symptoms that can be confused with other diseases.
​
Symptoms and diagnosis
The symptoms of glioblastoma can vary greatly and often occur suddenly. The most common symptoms include headaches, nausea, and behavioral changes. These symptoms often result from increased pressure in the skull and damage to the surrounding brain tissue. Patients may also suffer from neurological deficits, such as difficulty speaking or moving. Diagnosing glioblastoma is challenging because the symptoms can easily be confused with other conditions. Therefore, imaging techniques such as MRI or CT are crucial for an accurate diagnosis. A biopsy is also often performed to determine the exact type of tumor.
​
Causes and risk factors
The exact causes of glioblastoma are not yet fully understood. However, several factors have been identified as potential risk factors. Genetic predisposition plays a role; certain genetic changes are associated with an increased risk of developing glioblastoma. In addition, environmental factors such as exposure to ionizing radiation or certain chemicals are thought to increase the risk. Although many studies have been conducted, our understanding of the exact mechanisms behind the development of these tumors remains incomplete.
The challenges in treating glioblastomas are enormous and require a multidisciplinary approach. In the next section, we will take a closer look at the various treatment options currently available to combat the progression of this aggressive disease.
Treatment options for glioblastoma
Surgical removal of the tumor is a central component of glioblastoma treatment. The aim of this procedure is to remove as much tumor tissue as possible in order to reduce pressure on the surrounding brain tissue and improve the patient's quality of life. Microsurgical resection techniques have advanced significantly in recent years. Modern tools such as neuronavigation and fluorescence labeling are used in this procedure. Neuronavigation enables surgeons to precisely determine the exact location of the tumor in the brain and select the best possible approach.
Fluorescence labeling, on the other hand, uses special dyes that make tumor cells visible, thereby sparing healthy cells. These innovative methods help to increase the success rate of operations and speed up patients' postoperative recovery.
Radiation therapy
Surgical removal of the tumor is usually followed by radiation therapy. This treatment is used to kill any remaining tumor cells and minimize the risk of recurrence. Radiation therapy can be performed either as external radiation or brachytherapy. In external radiation, a high-energy beam is directed at the tumor, while in brachytherapy, radioactive sources are placed directly in the tumor tissue. Both methods aim to damage the DNA of the tumor cells, which inhibits their division and growth. However, it is important to note that radiation therapy can also damage healthy cells, which can lead to side effects such as fatigue, skin irritation, or neurological disorders. Careful planning and dosing are therefore crucial to minimize side effects while ensuring the effectiveness of the treatment.
​
Chemotherapy with temozolomide
Temozolomide is the standard drug used in chemotherapy for glioblastomas. It belongs to the group of alkylating agents and works by damaging the DNA of cancer cells, which prevents them from dividing. Temozolomide is often used in combination with radiation therapy to increase the effectiveness of the treatment. It is administered in cycles, with patients first undergoing a phase of treatment followed by a recovery phase. Typical side effects of temozolomide include nausea, vomiting, and changes in blood count, particularly a drop in granulocytes or lymphocytes and thrombocytes. These side effects sometimes require an adjustment in dosage or an interruption in therapy. Nevertheless, temozolomide has been shown to significantly prolong the survival time of patients with glioblastoma, making it an important part of the treatment approach.
The combination of these treatment approaches—surgical intervention, radiation therapy, and chemotherapy—forms the backbone of glioblastoma therapy. Nevertheless, the disease remains challenging and requires innovative approaches to improve treatment outcomes. In recent years, immunotherapy has established itself as a promising addition.
​
Immunotherapy as an innovative treatment option
​Dendritic cell therapy has proven to be a promising method for combating glioblastoma. This form of cancer immunotherapy uses dendritic cells, which play a key role in the immune system. They act as the body's “guardians” and are responsible for recognizing foreign cells, such as tumor cells, and triggering an immune response. In dendritic cell therapy, these cells are isolated from the patient's blood and treated with specific tumor antigens in the laboratory. After this activation, they are returned to the body, where they stimulate the immune system to target the tumor cells.
Compared to conventional chemotherapy, immunotherapy has significant advantages. On the one hand, the side effects are often less severe because the immune system is specifically activated and fewer healthy cells are affected. On the other hand, there is evidence that dendritic cell therapy can generate a sustained immune response that lasts for months or even years. These findings open up new perspectives in the treatment of glioblastomas and offer hope for many patients.
Research in this field is dynamic and promising; current studies are investigating various approaches to combining immunotherapies with traditional forms of treatment such as chemotherapy and radiation therapy. These integrative approaches could help to further improve survival rates while also enhancing patients' quality of life.

Research in this area is dynamic and promising; current studies are investigating various approaches to combining immunotherapies with traditional forms of treatment such as chemotherapy and radiation therapy. These integrative approaches could help to further improve survival rates while also enhancing patients' quality of life. One example of this is the combination of temozolomide with dendritic cell therapy, which has shown positive results in initial studies.
The use of immunotherapies in glioblastomas is an exciting field of research that is constantly yielding new insights. Scientists are working to understand the mechanisms by which the immune system recognizes and fights tumors. This could be significant not only for glioblastoma, but also for other types of cancer, greatly expanding the potential of these therapies.
It is important to emphasize that despite advances in immunotherapy, challenges remain. The heterogeneity of glioblastomas means that not all patients will respond equally to these therapies. It is therefore crucial that future research efforts focus on identifying biomarkers that can predict which patients will benefit most from dendritic cell therapy.
Given the complexity and aggressiveness of glioblastomas, it is essential that patients have access to the latest treatment options and are involved in decisions about their therapy.
The integration of innovative approaches such as dendritic cell therapy into existing treatment protocols could make a significant contribution to improving the prognosis for glioblastoma patients.

As understanding of immunological approaches to combating glioblastomas continues to evolve and new clinical trials take place, it will be exciting to see how these therapies become established in clinical practice and what progress can be made in improving patients' quality of life. In the following sections, we will take a closer look at current research findings and developments in the field of glioblastoma therapy.
​
Current research and developments
​Advancing research in the field of glioblastoma has led to a variety of new approaches in recent years that have the potential to revolutionize the treatment of these aggressive brain tumors. The scientific community has been working intensively to develop innovative forms of therapy to increase survival rates and improve patients' quality of life. Research efforts are focused on developing new therapeutic approaches for glioblastoma. These include targeted therapies that target specific molecular characteristics of the tumors, as well as new immunotherapies that activate the body's own immune system to fight cancer cells more effectively.
​
One promising area is the combination of existing therapies such as chemotherapy and radiation therapy with novel approaches such as dendritic cell therapy. This form of cancer immunotherapy uses dendritic cells to generate a targeted immune response against tumor cells. Current clinical trials are investigating how this therapy can be used in combination with traditional treatments to achieve synergistic effects. Initial results show
that patients receiving such combination therapy may benefit from improved efficacy and fewer side effects.
Another interesting research approach is the development of targeted therapies. These therapies target specific genetic changes that occur in many glioblastoma patients. One example of this is the inhibition of the enzyme IDH1, which is mutated in certain tumors. Studies show that patients with such mutations may respond better to targeted therapies. This personalized medicine opens up new possibilities for tailored treatment of glioblastomas and could help improve the prognosis for many patients.
Results and prospects
The results of new therapies show promising progress in the treatment of glioblastomas. In recent years, several clinical studies have been conducted that demonstrate positive results regarding the effectiveness of innovative approaches. For example, studies on dendritic cell therapy have shown that patients can experience a significant prolongation of their survival time. This is particularly encouraging, as glioblastomas are traditionally considered difficult to treat. The integration of such new therapies into existing treatment protocols could make a decisive contribution to improving patients' quality of life. In addition, the role of cytostatic drugs such as temozolomide continues to be intensively researched. Although it is a proven chemotherapy, there is evidence that its effectiveness can be enhanced by combining it with immunotherapies or targeted therapies. For example, the use of temozolomide in combination with dendritic cell therapy could lead to the immune system responding better to tumor cells while minimizing side effects.
Another aspect of the research focuses on the biological markers of glioblastomas. Biomarkers could help identify patients who would benefit most from specific treatments. This could not only increase the effectiveness of therapies, but also help avoid unnecessary side effects.
The identification of such markers is an active field of research and could be crucial for the personalized treatment of glioblastomas in the future.
Developments in glioblastoma research are dynamic and promising; current studies are investigating various approaches to combining immunotherapies with traditional forms of treatment such as chemotherapy and radiation therapy. These integrative approaches could help to further improve survival rates while also enhancing patients' quality of life. In the next section, we will take a closer look at the impact of treatment on the quality of life and prognosis of glioblastoma patients.
Quality of life and prognosis
Life expectancy for glioblastoma patients varies greatly depending on individual treatment. Typically, the average survival time is about 15 months, with some patients living significantly longer, while others may experience shorter periods.
The prognosis depends on various factors, including the patient's age, general health, tumor location, and response to treatment. Younger patients and those in better overall health tend to have better chances of survival. In addition, complete removal of the tumor plays a crucial role; the more tumor tissue that can be removed, the better the chances of longer survival. However, it is important to note that glioblastomas are usually aggressive and often return, which further complicates the prognosis.
The treatment of glioblastoma can have a significant impact on patients' quality of life. In addition to the physical challenges of the disease itself, such as pain or neurological deficits, patients often have to cope with the side effects of therapy. Chemotherapy and radiation therapy can lead to fatigue, nausea, and cognitive impairment, which can significantly affect the daily lives of those affected. These side effects can not only affect physical well-being, but also cause emotional and psychological distress.
Support from psychologists or self-help groups can be of great benefit in coping with emotional stress.
In addition to the physical and emotional challenges, it is important to consider the social aspects of quality of life.
Many patients find their social interactions limited by their illness. Activities that used to be enjoyable can become difficult due to fatigue or cognitive impairments. It is therefore crucial that family and friends are involved in this process in order to create a supportive environment. Therapeutic measures such as occupational therapy can help maintain or regain skills and promote independence.
Another aspect of quality of life concerns nutrition and lifestyle. A balanced diet can help improve overall well-being and strengthen the body during treatment. Studies show that a healthy diet has a positive impact on the quality of life of cancer patients and can even improve their response to therapy. Exercise and physical activity are also important; regular exercise can help reduce fatigue and increase mental well-being.
​
Psychosocial support plays an essential role in improving the quality of life of glioblastoma patients. Therapeutic interventions can help reduce anxiety and develop strategies for coping with the disease. Group sessions or individual conversations provide a space for sharing experiences and enable those affected to feel less isolated. Involving family members in the therapy process can also help to develop a better understanding of the challenges of the disease and provide emotional support for the patient.
Overall, it is clear that the quality of life of glioblastoma patients is influenced by a variety of factors. The combination of medical treatments, psychosocial support, and a healthy lifestyle can
help improve both the prognosis and well-being of those affected. It is essential that patients have access to comprehensive support services and are involved in decisions about their treatment.
Conclusion
Examining glioblastoma, one of the most challenging types of cancer, reveals not only the complexity of the disease itself, but also the remarkable advances that have been made in research and treatment. In summary, glioblastoma is a complex disease that requires multidisciplinary treatment. The combination of surgery, radiation therapy, and chemotherapy has proven essential in increasing survival rates and improving patients' quality of life. Particularly noteworthy is the role of dendritic cell therapy, an innovative immunotherapy that represents a promising approach to activating the body's own immune system to target tumor cells.
This therapy exploits the ability of dendritic cells to recognize foreign cells and trigger a specific immune response, which can lead to a more sustainable fight against glioblastoma. Integrating such novel approaches into existing treatment protocols could not only increase the effectiveness of therapies, but also help minimize the side effects associated with conventional treatments. Current research studies are already showing promising results and opening up new perspectives for patients suffering from this aggressive form of brain tumor.
For example, research is being conducted into how a combination of temozolomide and dendritic cell therapy can achieve synergistic effects to improve response to therapies while enhancing quality of life. These developments are particularly encouraging and offer hope for many patients and their families.
It is important to emphasize that despite all the progress that has been made, challenges remain, particularly due to the heterogeneity of glioblastomas, which requires personalized medicine. Future research efforts should aim to identify biomarkers that can predict which patients will benefit most from specific treatments. This makes it all the more crucial that patients have access to the latest information and treatment options and are actively involved in decisions about their therapy. Considering all these aspects, it remains exciting to observe how the therapeutic landscape for glioblastoma continues to evolve and what progress can be made in improving patients' quality of life.
