Presentation
Diffuse intrinsic pontine gliomas are diagnosed by their clinical signs and symptoms on presentation and their appearance on imaging. [ispn.guide]
Most common signs at presentation include corticospinal tract deficits, cranial nerve palsies and ataxia. [scielo.br]
At presentation, DIPG blood volume was 60 ± 27 % of that measured for normal cerebellum. Citrate, which is not detectable in normal brain tissue, was present in DIPG at concentrations of 3.81 ± 1.44 mmol/kg tissue. [ncbi.nlm.nih.gov]
Double vision (diplopia) is the most common presenting symptom for these tumors. Symptoms are usually present for 6 months or less at time of diagnosis. [checkorphan.org]

With pontine and cervicomedullary lesions, cranial nerve or long tract signs are observed commonly. Histopathologically, brainstem gliomas can range from WHO Grade 1 to 4. [emedicine.medscape.com]
Pontine and medullary DMG present insidiously with brainstem signs (cranial nerve deficits, long tract signs) and progress inexorably, usually causing death in 2 years. [neuropathology-web.org]
- Vertigo

Six months later, he presented ataxia syndrome with lateropulsion, star gait, dysarthria, aphasia, vertigo, and altered mental state. MRI showed an increase in the size of the tumor to 4.7 x 3.9 x 4.1 cm. [elsevier.es]

- Dizziness
Additionally, depending on the tumour’s localization and the patient’s age, the following symptoms can occur: rapidly increasing head-circumference (macrocephalus), developmental delay, headaches, backaches, nausea and vomiting in the morning, dizziness [kinderkrebsinfo.de]

Serum
- Lymphopenia
Adverse events of any grade reported in at least one treatment cycle include neutropenia, fatigue, loss of appetite, hypertension, nausea, and lymphopenia; only neutropenia and hypertension were reported as grade 3 adverse events. [curetechbio.com]
Treatment
Nanotechnology may offer therapeutic options for the treatment of DIPGs. Multiple nanoparticle formulations are currently being investigated for the treatment of DIPGs. [eurekaselect.com]
In this type of treatment, radiation is directed at the brainstem and surrounding tissues. [neurosurgeonsofnewjersey.com]

The doctor may also use a small section of the tumor to help them plan the most effective treatment. Treatment options for DIPG are limited. [cincinnatichildrens.org]
Prognosis
[…] of Pontine Glioma poor prognosis prognosis is tried to improve prognosis with therapy-optimising studies and preospective studies [hirntumorhilfe.org]
Due to the poor prognosis of diffuse intrinsic pontine gliomas, the limited therapy options, the relevant portion of EGFR expression and the unexpected good response to the therapy with OSAG 101 in the phase II study, a phase III study was planned in [clinicaltrials.gov]
Prognosis diffuse terrible prognosis 90-100% patients die within 2 years of diagnosis 6 focal (tectal glioma) excellent long-term survival with CSF shunting (essentially benign lesions) focal (other) good long-term prognosis with surgery (dorsally) exophytic [radiopaedia.org]
Etiology
How much of this variation is due to artifactual influences or etiologic differences has been the subject of many debates. Some reports have suggested a slight male preponderance, whereas others have failed to observe any sex predilection. [emedicine.medscape.com]
Within the umbrella of adult brainstem glioma, there is a subset of tumors that is similar in appearance and potentially similar in etiology to childhood DIPG, but with slightly older onset, generally affecting young adults. [frontiersin.org]

Prevention
The BBB is arguably the most formidable barrier for drug delivery to the brain and to brain tumors as it prevents drugs and drug delivery systems from reaching the pathological site. [era-learn.eu]

In animal experiments, drugs known as PRC2 and BET inhibitors helped block the activity of histone H3, preventing the growth of tumors and prolonging life. [healthline.com]
Prevention - Diffuse Intrinsic Pontine Glioma Not supplied. Diagnosis - Diffuse Intrinsic Pontine Glioma Diffuse pontine gliomas are located in the brainstem, at the base of the brain. They are usually diagnosed in children aged 5 to 10. [checkorphan.org]
Put together, these obstacles offer researchers a chance to revolutionize cancer research and prevention. It is even suggested that a cure to DIPG might result in a cure for almost every other type of cancer. For this reason, the cure starts now. [thecurestartsnow.org]
