background: central nervous system (cns) relapse in acute lymphoblastic leukemia was significantly decreased due to the use of new chemotherapyeutic agents, intrathecal chemotherapy and cranial irradiation. the purpose of this study was to compare the effectiveness of intrathecal (it) cns chemotherapy alone versus combination of it chemotherapy with cranial irradiation for prevention of cns rel...

OBJECTIVE To compare the efficacy of intrathecal methotrexate single therapy with three-drug combination therapy in patients with leptomeningeal carcinomatosis. METHODS Fifty-five patients who had pathologically proven leptomeningeal carcinomatosis of a solid tumor were evaluated in terms of pathological response. Group M (n = 29) received methotrexate 15 mg and group MHA (n = 26) received me...

OBJECTIVE To investigate the pharmacokinetics and toxicity of intravitreal chemotherapeutic agents in the rabbit eye for the potential treatment of primary intraocular lymphoma and other intraocular malignancies. METHODS The ocular pharmacokinetics of intravitreal methotrexate sodium (400 microg) was studied in 10 New Zealand white rabbits, and a single-compartment, first-order elimination mo...

Paraplegia following spinal injury is a rare complication subsequent to the administration of intrathecal chemotherapy; however, it is also one of the rare clinical features of central nervous system leukemia (CNSL). Distinguishing between the two is extremely important. The present study reports the case of a 46-year-old man who was diagnosed with acute lymphoblastic leukemia and subsequently ...

STUDY OBJECTIVE To determine the efficacy of methotrexate, vinblastine, and platinum chemotherapy in patients with diffuse unresectable malignant mesothelioma. DESIGN Patients with histologically confirmed malignant mesothelioma were evaluated for treatment with methotrexate, vinblastine, and cisplatin chemotherapy. If the patient had preexisting hearing loss or neuropathy, or was significant...

We report a patient with Burkitt’s lymphoma involving the liver and retroperitoneal lymph nodes who developed acute, progressive, quadriplegia associated with sphincter dysfunctions and an ascending sensory level after the 2 dose of intrathecal methotrexate. The motor deficits and the spinal dysfunction persisted in spite of discontinuation of the methotrexate, as well as treatments with intrat...

OBJECTIVES To determine epidemiological characteristics and clinical presentation of complete hydatidiform mole (CHM) and complications associated with prophylactic chemotherapy with oral methotrexate. SETTING Mulago hospital, Kampala. DESIGN Prospective study. METHODS Ninety-four patients with clinically and histologically confirmed complete hydatidiform mole admitted between 1/9/1995 an...

Methotrexate has proven to be effective in treating rheumatoid arthritis (RA), and is believed to be nononcogenic in the low weekly dose typically employed in the patients with RA. We report, however, a patient with RA in whom a rapidly enlarging diffuse large B-cell lymphoma developed in the left upper lung after weekly treatment with methotrexate for 5 years. The patient had a positive serum ...

Results from four consecutive trials, conducted from 1982 by members of the Scandinavian Sarcoma Group, are reviewed. A total of 330 classical osteosarcoma patients were enrolled. In all trials chemotherapy was based on the three active drugs, methotrexate, doxorubicin and cisplatinum and for the latter trials also ifosfamide. Post-operative chemotherapy was stratified by histological response ...

In earlier combination chemotherapy regimens for childhood acute lymphocytic leukemia, nervous system leukemia terminated complete remission in over half the patients in a median time of 11 months. In the present study, cranial radiation (2400 R, 60Co) and intrathecal methotrexate given early in remission were added to combination chemotherapy in an attempt to prevent or delay central nervous s...
