Treatment of Low-Risk Neuroblastoma
In North America,the Children’s Oncology Group (COG) is investigating a risk-based neuroblastoma treatment plan that assigns all patients to low-,intermediate-,and high-risk groups based on age,International Neuroblastoma Staging System (INSS) stage,and tumor biology (i.e.,MYCN gene amplification,Shimada classification,and DNA ploidy).[ 1 ] (Risk groups are defined in Table 1 of the Stage ...
Recurrent Pituitary Tumors Treatment
Standard Treatment Options for Recurrent Pituitary TumorsStandard treatment options for recurrent pituitary tumors include the following:Radiation therapy for postsurgical recurrence, which offers a high likelihood of local control.[1,2]Reirradiation, which provides long-term local control and control of visual symptoms.The question and selection of further treatment for patients who relapse is dependent on many factors, including the specific type of pituitary tumor, prior treatment, visual and hormonal complications, and individual patient considerations. Treatment Options Under Clinical Evaluation for Recurrent Pituitary TumorsTreatment options under clinical evaluation for recurrent pituitary tumors include the following:Stereotactic radiation surgery.[4,5,6]Current Clinical TrialsCheck for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with recurrent pituitary tumor. The list of clinical trials can be further narrowed by
Prolactin-Producing Pituitary Tumors Treatment
Standard Treatment Options for Prolactin (PRL)-Producing Pituitary TumorsStandard treatment options for PRL-producing pituitary tumors include the following:Dopamine agonists, such as cabergoline and bromocriptine.[1,2,3,4,5] Surgery (second-line).[1,2]Radiation therapy (occasionally).[1,2]When the pituitary tumor secretes PRL, treatment will depend on tumor size and the symptoms that result from excessive hormone production. Patients with PRL-secreting tumors are treated with surgery and radiation therapy.Most microprolactinomas and macroprolactinomas respond well to medical therapy with ergot-derived dopamine agonists, including bromocriptine and cabergoline. For many patients, cabergoline has a more satisfactory side effect profile than bromocriptine. Cabergoline therapy may be successful in treating patients whose prolactinomas are resistant to bromocriptine or who cannot tolerate bromocriptine, and this treatment has a success rate of more than 90% in patients with newly

Histopathologic Classification of Childhood Ependymal Tumors
In the most recent World Health Organization (WHO) classification of brain tumors,ependymal tumors are classified into four main subtypes:[ 1 ] Subependymoma (WHO Grade I). Myxopapillary ependymoma (WHO Grade I). Ependymoma (WHO Grade II). Variants include cellular,papillary,tanycytic,clear cell,and mixed. Anaplastic (also known as malignant) ependymoma (WHO Grade III).
