PURPOSE To review the clinical data, imaging findings, and intermediate outcomes of a series of children with hemorrhagic vasculopathy after treatment for intracranial neoplasia. METHODS We retrospectively analyzed the medical records and imaging examinations of 20 pediatric patients (ages 1 to 15 years) with intracranial neoplasia in whom delayed intracranial hemorrhage developed after crani...

Nine younger children (mean age 6-3 years) and 6 older children (mean age 9-0 years), previously treated for acute lymphoblastic leukaemia by cranial irradiation and subsequently by 2 or 3 years of chemotherapy, were assessed in terms of intellectual development in relation to 15 controls, matched individually for age, sex, and social background. All children were functioning within a normal ra...

In acute lymphoblastic leukemia (ALL), central nervous system (CNS) prophylaxis with cranial irradiation plus 5 doses of intrathecal methotrexate (i.t. MTX) reduces the incidence of CNS relapse to 7%-15%. However, increased evidence of CNS delayed toxicity started to be recognized as CT scan abnormalities and neuropsychologic alterations, mainly in children. Two questions were analyzed in the p...

Aims. We have audited the changes in treatment practice for small-cell lung cancer (SCLC) presented to a single multidisciplinary team (MDT) at Doncaster and Bassetlaw Hospitals between January 1998 and December 2005. Materials and Methods. The MDT database was used to identify all patients with SCLC. Anonymised demographic, treatment, and outcome details were extracted from the database supple...

INTRODUCTION The survival and epidemiology of small-cell lung cancer (SCLC) in Singapore has not been described. We aim to present the characteristics as well as determine the survival outcome and important prognostic factors for SCLC patients. MATERIALS AND METHODS A retrospective analysis of SCLC patients diagnosed from 1999 to 2002 was conducted at the Outram campus, Singapore. Clinical ch...

We describe a patient with radiation-induced meningioma 12 years after cranial irradiation for ectopic germinoma. PET scans with fludeoxyglucose F 18 showed a high glucose metabolic rate in the meningioma despite a benign histologic appearance.

A case of herpes encephalitis is reported in a patient who had cranial irradiation and high dose steroids for a cerebral neoplasm. Before radiotherapy the patient had had herpetic infections of the skin and eye.

A large proportion of patients with carcinoma of the lung may benefit from the use of radiation therapy. Operable patients have not been shown to benefit from preoperative irradiation, but postoperative irradiation has improved survival in those found to have involvement of hilar or mediastinal lymph nodes. Radiation therapy is the only potentially curative treatment for patients who are inoper...

Patients with limited-stage small-cell carcinoma of the lung are treated with combined-modality therapy with the intent to cure. Standard therapy consists of platinum-based combination chemotherapy, thoracic irradiation, and for responders, prophylactic cranial irradiation. Despite this aggressive approach, too few patients achieve 5-year survival. In the past several years, new chemotherapeuti...

An 11-year-old boy with acute lymphoblastic leukemia had received prophylactic cranial irradiation (1800 cGy /10 fractions) and intrathecal methotrexate. Five years later, he developed a glioblastoma multiforme in the right frontal region while the leukemia was in remission. It is possible that the glioma may have been induced by radiation and /or chemotherapy.
