Diffuse infiltrative low grade gliomas (LGG) account for approximately 15 % of all gliomas. The prognosis of LGG differs between high-risk and low-risk patients notwithstanding varying definitions of what constitutes a high-risk patient. Maximal safe resection optimally is the initial treatment. Surgery that achieves a large volume resection improves both progression-free and overall survival. ...

In order to evaluate the role of proteolysis in acquired von Willebrand's disease (vWD) associated with the myeloproliferative syndrome, we have determined the relative quantity of von Willebrand factor (vWF) fragments as compared with the intact 225 kDa subunit in four patients. The plasma vWF of each individual lacked large multimers; each had a prolonged bleeding time; and both platelet and ...

The purpose of the trial was to determine the survival and incidence of secondary tumors in children with medulloblastoma receiving radiotherapy plus chemotherapy. Three hundred seventy-nine eligible patients with nondisseminated medulloblastoma between the ages of 3 and 21 years were treated with 2340 cGy of craniospinal and 5580 cGy of posterior fossa irradiation. Patients were randomized bet...

We describe a case of anaplastic astrocytoma in a 14-year-old boy arising at the site of a dysembryoplastic neuroepithelial tumor (DNT) 3 years after combined radiation and chemotherapy. The subtotally excised superficial right temporoparietal tumor was originally diagnosed as mixed oligoastrocytoma in 1974; the patient was treated with radiation therapy postoperatively. One year later he under...

Current strategies for treatment of small cell carcinoma of the lung are based on the concept of the disease as a systemic condition, requiring systemic treatment. Small cell carcinoma is considerably more sensitive to anticancer drugs than other bronchogenic neoplasms. The most widely used agents are cyclophosphamide, adriamycin, vincristine, CCNU, methotrexate, and VP 16-213. The superiority ...

Procarbazine HCl is a 'nonclassical' oral alkylating anticancer agent that was first synthesized in the late 1950s. It has been used in the treatment of many cancers, but its main use is in the treatment of Hodgkin's lymphoma and brain tumors and, to a lesser extent, Non-Hodgkin's lymphoma and primary central nervous system lymphoma. Procarbazine is a prodrug that undergoes metabolic transforma...

PURPOSE OF REVIEW This review summarizes recent studies on the predictive value of molecular markers in adult gliomas, including 1p/19q codeletion, MGMT methylation, IDH mutation and markers identified using omics and next-generation sequencing studies. RECENT FINDINGS The long-term results of the Radiation Therapy Oncology Group and European Organization for Research and Treatment of Cancer ...

MONOCLONAL ANTIBODIES promise to revolutionize our ability to define and analyse the molecular components of tumour cell surfaces. To date these antibodies have been of mouse or rat origin. Here we report the production of human monoclonal antibodies by the fusion of intratumoral lymphocytes from a patient with a malignant glioma and a mouse myeloma line. Four such antibodies were found to bind...

BEAM (BCNU, etoposide, cytrabine, melphalan) is the most widely used high dose chemotherapy regimen for autologous transplant in lymphoid malignancies. We report our early experience with an alternative regimen LEAM where BCNU was replaced with the oral analogue CCNU (lomustine) to tide over the non-availability of BCNU. Fifty one patients of relapsed or refractory lymphoma who received BEAM (n...

BACKGROUND AND OBJECTIVES Treatment of acute myeloid leukemia (AML) in older patients remains unsatisfactory. The BGMT 95 trial for older patients set out to improve the outcome of these patients by adding a third drug (lomustine) to a 5+7 idarubicin and cytarabine schedule at induction and evaluating intermediate-dose cytarabine as consolidation. DESIGN AND METHODS A multicenter randomized t...
