What this trial studies

This observational study reviews the use of high-dose methotrexate in cancer patients, focusing on patterns of administration, supportive care measures, and the incidence of delayed methotrexate elimination and acute kidney injury. It aims to compare current practices against established guidelines to identify gaps in management and variations in outcomes across different centers and patient demographics. The study will also document the use of glucarpidase and any associated toxicities during treatment.

Who should consider this trial

Good fit: Ideal candidates include adults and children diagnosed with any type of cancer who have received high-dose methotrexate chemotherapy.

Not a fit: Patients who have not received high-dose methotrexate or those without available medical records will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the management of high-dose methotrexate therapy, potentially reducing the risk of acute kidney injury and enhancing treatment outcomes for cancer patients.

How similar studies have performed: Other studies have explored high-dose methotrexate treatment, but this study aims to provide a comprehensive evaluation of current practices, making it a valuable addition to existing research.
