|July 11, 2018
Summary
Photodynamic therapy (PDT) shows promise as a safe and effective adjuvant treatment for malignant gliomas, potentially increasing survival rates. Protective measures minimize side effects like photosensitivity, making PDT a viable option for brain tumor management.
Area of Science:
- Oncology
- Neurosurgery
- Photomedicine
Background:
- Malignant brain tumors, particularly high-grade gliomas like glioblastoma multiforme (GBM), present significant therapeutic challenges.
- Photodynamic therapy (PDT) has emerged as a potential treatment modality for these aggressive neoplasms.
Purpose of the Study:
- To evaluate the efficacy and safety of photodynamic therapy (PDT) as an adjuvant treatment for malignant gliomas.
- To assess the impact of PDT on patient survival rates compared to conventional therapies.
Main Methods:
- Meta-analysis of observational studies involving over 1,000 patients with high-grade gliomas.
- Review of controlled trials comparing PDT with standard treatment protocols for glioblastoma multiforme (GBM).
Main Results:
- Median survival for newly diagnosed and recurrent GBM patients treated with PDT was 16.1 and 10.3 months, respectively.
- Some studies indicated an increase in long-term survival rates with PDT.
- Controlled trials showed a statistically significant survival benefit of PDT over conventional management for GBM.
Conclusions:
- Photodynamic therapy (PDT) is a safe and effective adjuvant therapeutic option for both newly diagnosed and recurrent malignant gliomas.
- Aggressive tumor resection is crucial for maximizing the efficacy of PDT.
- Transient photosensitivity is the primary adverse event, manageable with protective measures.

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Cognitive Therapy
1.1K
Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...
