Activity No activity restrictions are necessary. Few drugs are of benefit in this disease. Exceptions are glucocorticoids, which can aid in decreasing vasogenic edema.

Mannitol is useful in the acute setting when the physician is faced with a herniating patient. Chemotherapy is used as adjuvant therapy in some patients.

Administration of toxic compounds that affect choroid plexus papilloma radiation therapy organ systems is in the realm of the experienced oncologist. Drug Category: Glucocorticoids Reduction of vasogenic edema is the role of glucocorticoids in malignant brain tumors.

They can be very effective in medulloblastoma and can even alleviate hydrocephalus by reopening CSF pathways in the posterior fossa. Although any of several glucocorticoids can be used, dexamethasone is used most often. Equivalent doses of various glucocorticoids are 0.

Not for long-term use. Adult Dose 1. Chemotherapy usually is administered on choroid plexus papilloma radiation therapy inpatient basis. Further Outpatient Care Imaging is the primary mode of monitoring residual disease, efficacy of continuing medical treatment, and recurrence or metastasis.

Because medulloblastoma is aggressive, frequent monitoring is essential. MRI should be repeated every 3 months the first year; every 4 months the second year; every 6 months the following 3 years; and yearly thereafter.

Radiation therapy is an outpatient procedure. Any signs of change in mental status are indications for outpatient visits, as they may herald hydrocephalus and possible recurrence. Lower cranial nerve or cerebellar signs also may signal recurrence.

Taper steroids and monitor adverse effects. However, chemotherapy and radiation therapy may exacerbate edema and necessitate low-dose corticosteroids for a short period of time. Antiepileptic medication usually is necessary when the tumor is located in the posterior fossa. Spread of disease to the supratentorial compartment may cause seizures and indicate antiseizure medication. Transfer Transfer may be necessary for treatment at a center familiar with pediatric neurosurgery, pediatric oncology, or pediatric radiotherapy.

Complications Hydrocephalus the most common complication of medulloblastoma can cause secondary visual problems. Cerebellar dysfunction the second most common complication of the disease may lead to problems with coordination and gait.

Cranial nerve palsy from brainstem involvement can lead to difficulties with vision, speech, and swallowing. With subarachnoid spread to the spinal cord, the choroid plexus papilloma radiation therapy complications are radiculopathy and weakness.

Complications accompany the treatment of medulloblastoma. Fortunately, most of these complications are transient. The most common complication after surgery is a temporary worsening of ataxia accompanied by nystagmus.

One of the most commonly cited complications is cerebellar mutism. The anatomic site of origin is thought to be the deep choroid plexus papilloma radiation therapy nuclei.

The constellation of symptoms includes apathy, minimal-to-absent speech, emotional lability, and refusal to initiate movement. Hemiparesis can accompany mutism. Lower cranial nerves are intact, but the syndrome is accompanied by a swallowing apraxia. It becomes apparent several hours after surgery and persists for several weeks, usually resolving completely.

Other complications include a temporary Parinaud syndrome and pneumocephalus. A common complication of any surgery in the posterior fossa is aseptic meningitis. This can be alleviated with a short course of corticosteroids. Complications of radiation therapy have been discussed previously and include lowered IQ, small stature, endocrine dysfunction, behavioral abnormalities, secondary neoplasms, and radiation necrosis of the white matter.

Chemotherapy also has numerous adverse effects on multiple organ systems including renal toxicity, ototoxicity, hepatotoxicity, pulmonary fibrosis, and gastrointestinal disturbance.

Methotrexate, choroid plexus papilloma radiation therapy used in human papillomavirus infection cancer with irradiation, can cause permanent necrotizing leukoencephalopathy. Prognosis Medulloblastoma is a very aggressive tumor. Even vaccino x papilloma virus a good response to surgery and radiation, recurrence is common; most recurrences occur within 2 years after treatment.

The most common location of recurrence is at the primary tumor site in the posterior fossa. With the use of adjuvant chemotherapy, incidence of recurrence in the spinal canal and the supratentorial region seems to decrease. Bone is the most common site of systemic metastasis; regional lymph node sites follow. The Collin law was first hypothesized for Wilms tumor and has been expanded since to cover many pediatric tumors thought to be congenital in origin.

The Collin law states that, if a tumor has not recurred in a period of time equal to age of patient plus 9 months, that patient can be considered to be cured. The Collin choroid plexus papilloma radiation therapy generally holds for medulloblastoma; however, several late recurrences longer than 10 years after benzimidazole anthelmintic drugs have been reported.

Greater age at diagnosis has been associated with a better prognosis, most likely because adults more often harbor the less aggressive desmoplastic variant of medulloblastoma. Why females have a longer recurrence-free interval is not understood.

Patient Education Teach patients and families about early signs of hydrocephalus, especially if the patient has a ventricular shunt in place. Perform neuroimaging studies promptly if findings of an exhaustive gastrointestinal evaluation for vomiting are normal.
