Purpose

The use of cyclosporine and mini-dose methotrexate (MTX) is a common strategy for graft-versus-host disease (GVHD) prophylaxis in allogeneic transplants. We investigated whether patients who receive fewer than the planned MTX doses are at increased risk for GVHD.

Methods

The study cohort included 103 patients who received allogeneic transplants at the Department of Pediatrics of The Catholic University of Korea College of...

Jun Ah Lee, Min Suk Kim, Jin Kyung Lee, Dong Ho Kim, Young Joon Hong, Won Seok Song, Wan Hyeong Cho, Soo-Yong Lee, Jung Sub Lim, Kyung Duk Park, Dae-Geun Jeon
Clin Exp Pediatr. 2009;52(5):581-587.   Published online May 15, 2009
Purpose : To evaluate the correlation between serum methotrexate (MTX) peak levels and clinical outcome of osteosarcoma, as well as to determine the correlation of these levels with the histologic response and event-free survival (EFS). Methods : To maintain the homogeneity of the study population, we selected 52 patients with localized extremity osteosarcoma who had received two cycles of neoadjuvant...
Leukoencephalopathy after CNS Prophylactic Therapy in Pediatric Hematologic Malignancy
Jun Hwa Lee, Sun Min Lee, Eun Jin Choi, Kun Soo Lee
Clin Exp Pediatr. 2003;46(6):566-571.   Published online June 15, 2003
Purpose : Leukoencephalopathy(LE) is one of the most serious complications in children with hematologic malignancies during the course of treatment. Early recognition is important to reduce the impact and sequelae from LE. We therefore investigated the clinical features of LE following central nervous system(CNS) prophylaxis in children with hematologic malignancies and evaluated the significance of regular check-ups of brain MRI. Methods...

Seon Woo Lee, Eun Hye Park, Hyun-Sang Cho, Jae Kook Cha, Hae Ran Lee
Clin Exp Pediatr. 2001;44(9):1066-1069.   Published online September 15, 2001
Intrathecal administration of methotrexate(IT-MTX) has constituted the standard approach to prophylaxis and treatment of central nevous system(CNS) leukemia. We experienced a quadriplegia and motor aphasia in a 14-year-old boy following repeated IT-MTX for the prophylaxis of meningeal leukemia. He was diagnosed as ALL without CNS involvement and treated by CCG- 1882 protocol. IT-MTX was administered for CNS prophylaxis. The patient began complaining of urinary incontinence,...

This study was conducted to investigate plasma levels of oral methotrexate in rabbits and children receiving maintenance chemotherapy for acute lymphocytic leukemia. Eight New Zealand white rabbits, weighing 2kg in body weight, were divided into 3 groups and 5mg of methotrexate from 3 different manufactorying company was administered to the each group rabbits via nasogastric tube.

This study was conducted to investigate the effects of CNS prophylaxis with 1800 cGy cranial irradiation and intrathecal methotrexate (MTX) chemotherapy on intellectual function of the chil- dren with acute lymphocytic leukemia (ALL). Thirteen longterm survivors with ALL who were treated with 1800 cGy cranial irradiation and intrathecal MTX for CNS prophylaxis at pediatric department of Yeungnam University Hospital from May, 1983 to November, 1988...

Allogenic bone marrow transplantation was done with Korean unspecified rabbits. Fresh bone marrow cell of different sex was infused to the recipient. The study group was divid- edfive groups according to immunosuppresive drugs. Each group was consited of 20 rebbits, was exposed to 1200 Rad. Group A, which were not have bone marrow transplantation, showed 100% mortality rate after 8 weeks. Group 8, which did not...
