How is DIPG treated?

How is DIPG treated? 1 Radiation therapy — currently, is the primary therapy for newly diagnosed DIPG in children older than 3. 2 Chemotherapy — is being used along with radiation therapy and other biologic agents in multiple trials... 3 Surgery — is rarely used to diagnose DIPG because of the risks involved in surgery in this area of the brain.

Is there a role for chemotherapy in the treatment of DIPG?

Currently, because there is no established role for chemotherapy for DIPG in children (radiation is the standard treatment),75decisions with regard to the addition of radiosensitizers should be based on the clinical and practical matters of the case. Salvage radiation therapy

What is the main issue with DIPG?

The main issue with DIPG is that most of these tumors are not classified by grade because surgery to obtain tissue by biopsy or to remove the tumor is not safe because of the location of the tumor. When these tumors are biopsied, they are usually grade III or grade IV tumors, which tend to behave very aggressively.

Is proton therapy effective in the treatment of DIPG?

Traditionally, proton therapy has been reserved for patients with potentially curable brain tumors because the poor prognosis of high-grade lesions, such as DIPG, mitigates the potential reduction in long-term toxicities.94However, further trials investigating the role of proton RT in the treatment of DIPG may be warranted. Conclusions

Where is DIPG located?

Diffuse intrinsic pontine glioma (DIPG) is a brain tumor that is highly aggressive and difficult to treat. It occurs in an area of the brainstem (the lowest, stem-like part of the brain) called the pons, which controls many of the body's most vital functions such as breathing, blood pressure, and heart rate.

Does St Judes treat DIPG?

This drug targets a growth pathway that is overactive in most DIPGs and similar brain tumors. He's also part of a St. Jude clinical trial that aims to push DIPG treatment — which hasn't significantly advanced in more than 50 years — a major step forward.

What is the best treatment for DIPG?

How is DIPG treated? Radiation therapy — currently, is the primary therapy for newly diagnosed DIPG in children older than 3. It uses high-energy X-rays from a specialized machine or other types of radiation to kill cancer cells and shrink tumors (stop them from growing).

Where does DIPG start?

In DIPG, a tumor forms in the stem of the brain in an area called the pons. It's in the lower part of the brain that controls vital body functions like blood pressure, heart rate, swallowing, eyesight and eye movement, balance, and breathing. DIPG is a kind of glioma, or a tumor that starts in the brain's glial cells.

Is Kaleigh Lau still alive?

Why can't DIPG be operated on?

First, because the pons is located in the center of the brain, a surgeon could not get to the tumor without damaging the surrounding portions of the brain. Second, even if the tumor could be accessed, total removal would be impossible. A DIPG tumor is not a solid, well-defined mass like some tumors.

What's the longest someone has lived with DIPG?

How rare is DIPG?

DIPGs are relatively rare , and the diagnosis and treatment of DIPG is complex and involves multiple specialists. The experts working with the DIPG Registry recommend that patients and families receive a definitive diagnosis and care at comprehensive, experienced pediatric medical centers with dedicated pediatric neuro-oncologists, neurologists, neuroradiologists, and neurosurgeons. Such centers usually offer multidisciplinary clinics, which allow patients to see multiple specialists during a single visit. This facilitates the close coordination of care. Most specialized pediatric neuro-oncology programs also offer support services such as neuropsychological consultation and school intervention professionals. These centers usually participate in collaborative clinical research groups such as the Children’s Oncology Group or the Pediatric Brain Tumor Consortium, which sponsor clinical trials of experimental treatments.

What is proton beam therapy?

Proton beam therapy is a specific type of radiation therapy that uses proton particles for treatment rather than the photons (x-rays) that are used for most radiotherapy . Protons have an anti-tumor effect that is very similar to conventional photon radiotherapy.

Is chemo effective against DIPG?

Current chemotherapy is generally not effective against DIPG. Most cancer -killing drugs are not able to get into the tumor at all, which seems to be protected by the high pressure inside the pons and by the blood-brain barrier, which prevents most drugs given orally or intravenously from reaching the brain.

Can a child with DIPG go to a hospital?

Sometimes, children with DIPG and their families can travel to a hospital with a specialized brain tumor program for diagnosis and expert advice but receive ongoing care at a hospital closer to home.

How does immunotherapy help with DIPG?

For DIPG patients, this can effectively cause inflammation and swelling in the pons that may need to be treated with steroids. The swelling and immune response can be so overwhelming that is can be worse than the tumor and have poor outcomes. Because of this, oncologists need a better understanding of the immune response and how it can be modulated before immunotherapies are used in DIPG and the pediatric population. There are high hopes that within the next few years immunotherapies will be an option for treating DIPG because, in theory, the body’s immune system should be able to bypass the BBB to help fight tumors but the side effects from that are still a very real issue.

Convection Enhanced Delivery (CED) is a technique of inserting a small catheter directly into the DIPG, the pontine tumor, to deliver drugs. With other delivery methods, typically only 10% of a dose is able to cross the Blood Brain Barrier (BBB). CED is a way to bypass the BBB and deliver drugs at high concentrations into the DIPG tumor.

What is intra-arterial chemo?

Intra-arterial is a method that delivers chemotherapy to the DIPG through a small catheter that is inserted into an artery of the brain. This specific technique is used in other types of tumors, especially retinoblastoma, tumors of the eye.

Where are DIPGs found?

DIPGs are found in the pons (the middle portion of the brainstem), and, grow throughout (“infiltrate”) the pons, taking up at least half of this important structure. They can grow into other area of the brainstem, and grow into the CSF-filled fourth ventricle next to the pons.

What is a DMG in pediatrics?

Pediatric diffuse intrinsic pontine gliomas (DIPGs)/ diffuse midline glioma (DMG) are brain tumors that are diagnosed in children (peak incidence 5-9 years old). They make up around 10% of all pediatric brain tumors.

Where are high grade gliomas found?

High grade gliomas are usually found in different locations based on the age of the patient (childhood high-grade glioma is usually in the deeper structures such as the thalamus, while adolescent high-grade glioma is often in the more superficial cortex).

What are the genes that are mutated in DMG?

Other important genes that are mutated in DMG include the ACVR1 gene, which is involved in developmental regulation, the tumor suppressor gene TP53 (p53), and other genes that result in growth and proliferation of DMG cells, including MYC, PDGFRA and PI3KCA . The molecular features of a DMG may impact tumor prognosis and treatment response. Current investigational therapies are adapted to these molecular features.
