Safety comparison of high-dose methotrexate via different intravenous infusion devices in pediatric patients with malignant brain tumors
To compare the safety of high-dose methotrexate (HD-MTX) via peripherally inserted central catheter (PICC) and totally implantable venous access port (TIVAP) in pediatric patients with malignant brain tumors.
METHODS
2
Patients with malignant brain tumors who received HD-MTX via PICCs or TIVAPs in our hospital from July 2018 to April 2022 were retrospectively analyzed. Clinical data were collected to compare differences in blood concentration of methotrexate (MTX),the incidence of adverse events (including adverse drug reactions and catheter-related complications) and length of stay in hospital. Multivariate linear regression was applied to analyze the factors that influenced the blood concentration of MTX.
RESULTS
2
A total of 107 patients were included in the study,with 65 patients in the PICC group and 42 patients in the TIVAP group. Blood concentration of MTX at 24 h (
C
24 h
) in TIVAP group was significantly higher than PICC group [(126.87±61.99) μmol/L vs. (102.45±48.77) μmol/L,
P
<0.05). There was no significant difference in blood concentration of MTX at 42 h (
C
42 h
),compared with PICC group (
P
>0.05). Results of multivariate linear regression analysis showed that TIVAP was associated with the increase of
C
24 h
(
P
<0.05). No significant differences were observed in the incidence of adverse events and the length of stay in the hospital between 2 groups (
P
>0.05).
CONCLUSIONS
2
Risk of adverse events is not increased,although the MTX
C
24 h
level is elevated after administration of TIVAP. TIVAP is a safe choice for HD-MTX therapy with implementing therapeutic drug monitoring.
