Symptoma

Diffuse Astrocytoma

In the present case, a low-grade diffuse astrocytoma component had colocalized with the epithelioid glioblastoma. [ncbi.nlm.nih.gov]

The most common presenting feature ( 40% of cases) is a seizure. This is particularly the case in adults. Headaches are often also present. [radiopaedia.org]

  • Chills

    First-strand cDNA was synthesized as follows: 1 μg of DNase-treated total RNA together with 0.5 μg of oligo(dT) 12–18 (Pharmacia, Uppsala, Sweden) in a total volume of 11 μl were heated to 70 C for 10 min and then chilled on ice. [cancerres.aacrjournals.org]

  • Joint Stiffness

    Characteristics include red or dark patches on the skin; burning, itching, swelling, hardening, and tightening of the skin; yellow spots on the whites of the eyes; joint stiffness with trouble moving or straightening the arms, hands, legs, or feet; pain [emedicine.medscape.com]

  • Scintillating Scotoma

    A 29-year-old man presented with scintillation scotoma. MR imaging demonstrated a diffuse lesion in right parahippocampal gyrus. He underwent a biopsy, and the diagnosis was diffuse astrocytoma. [ncbi.nlm.nih.gov]

  • Dysphasia

    […] sixth decade and peak in the seventh to eight decades. [2, 3] Clinical Features Clinical symptoms of diffuse astrocytomas are the result of brain irritation (eg, seizures), increased intracranial mass (eg, headaches), or brain invasion (eg, hemiparesis, dysphasia [emedicine.medscape.com]

  • Neglect

    The possibility that tumors develop novel aberrations, with relevant biological properties, is often neglected. [molecularcytogenetics.biomedcentral.com]

[…] tumors Other studies EEG may be used to evaluate and monitor epileptiform activity ECG and chest radiographs are indicated to evaluate operative risk CSF studies may be used to rule out other diagnoses (eg, metastasis, lymphoma, medulloblastoma) See Workup [emedicine.com]

/ Standard of Care Treatment options depends on the overall health of the person, the type, size, and location of the tumour, if and how far it has spread and previous treatment received. [braintumour.ca]

It is recognized as a malignant disease with no clear standard of care for treatment, and a poor prognosis for survival. [neuro-oncology.oxfordjournals.org]

Prognosis A prognosis is an estimate of the likely progress of a disease after a diagnosis, based on an average patient group. [braintumour.ca]

We have found it difficult and confusing to understand the treatment options and prognosis. We eventually chose radiation therapy (whole brain radiation) and temodar. Radiation is now complete and temodar continues. [csn.cancer.org]

Poorer prognosis is associated with older age and low clinical performance score at diagnosis. [emedicine.medscape.com]

It is recognized as a malignant disease with no clear standard of care for treatment, and a poor prognosis for survival. [neuro-oncology.oxfordjournals.org]

The term “brain tumor” refers to a collection of neoplasms, each with its own biology, prognosis, and treatment; these tumors are better identified as “intracranial neoplasms,” since some do not arise from brain tissue (e.g., meningiomas and lymphomas [intl-content.nejm.org]

Pathophysiology Regional effects of astrocytomas include compression, invasion, and destruction of brain parenchyma. [emedicine.com]

[…] genomewide data from multiple platforms delineated three molecular classes of lower-grade gliomas that were more concordant with IDH, 1p/19q, and TP53 status than with histologic class. [5, 6, 7] These findings were also reported in a 2013 study. [8] Pathophysiology [emedicine.medscape.com]
