BACKGROUND To assess feasibility, acute toxicity, and efficacy of intraventricular methotrexate administered as part of the primary therapy in medulloblastoma. METHODS From 2001 to 2007, 240 patients < 22 years from 61 treatment centres were registered. Patients received 2-3 cycles of intraventricular methotrexate with systemic chemotherapy in three different treatment arms of the prospective...
BACKGROUND Aggressive fibromatosis is a rare but invasive tumor infiltrating widely between fascia and muscle fibers. It has a high tendency to be locally recurrent despite complete resection. Effectiveness of adjuvant treatment for aggressive fibromatosis including radiotherapy, pharmacological agents, hormonal treatments, and chemotherapy have been previously reported. The purpose of this art...
•There is no consensus on optimal treatment for GTN and brain metastases.•Brain metastasis treated with craniotomy and intravenous, EMA-CO chemotherapy•Intravenous high-dose methotrexate may be adequate to treat brain metastases.
Methotrexate is a widely used cytostatic in chemotherapy cocktails for the treatment of cancer but is associated with cognitive impairment. Previous animal studies indicated that methorexate decreases hippocampal cell proliferation, which might contribute to the observed cognitive impairment. However, clinical studies have shown that cognitive impairment can also be noticed in some cancer patie...
The antifolate methotrexate is one of the most successful drugs in cancer chemotherapy. Although its efficacy is widely attributed to a decrease in nucleotide biosynthesis (1), methotrexate is known to increase homocysteine (2), a compound associated with an elevated risk of heart disease, Alzheimer's disease (3), and neural tube defects (4). A potential mechanism for the detrimental effects of...
PURPOSE High-dose methotrexate based chemotherapy is the standard treatment for patients with newly diagnosed primary central nervous system lymphoma (PCNSL). The role of rituximab is controversial because of its large size, which limits its penetration of the blood-brain barrier. In this study, we investigated the efficacy and tolerability of adding rituximab to methotrexate-cytarabine-dexamet...
UNLABELLED In this retrospective study on vitreoretinal lymphoma, there was significant change in diagnosis and treatment trends over 17 years at a single institution. Fine needle aspiration biopsy had replaced vitrectomy to collect vitreous sample and external beam radiotherapy in combination with systemic chemotherapy was replaced by intravitreal methotrexate and rituximab, which regressed vi...
Purpose: Low-dose metronomic chemotherapy is an emergent treatment schedule in which low doses of cytotoxic agents are given orally continuously, with no or short drug-free intervals. In general, it provides better tolerance, especially in patients who have been previously exposed to other oncologic treatments, with a favorable cost-effectiveness profile. It is well known that all these low-dos...
BACKGROUND Combination chemotherapy of methotrexate, actinomycin D and cisplatin (MAP) is reported to be effective against gestational choriocarcinoma. METHODS Eight patients with metastatic testicular cancer who had elevated beta-hCG were treated with MAP. They included three refractory cases and two relapsed cases. An additional three patients received MAP as part of the induction therapy. ...
