Lymphatic Malformation, Pediatric
Conditions
Keywords
cervico-facial, rapamycin
Brief summary
To evaluate the efficacy of Rapamycin in extended cervicofacial lymphatic malformations in pediatric patients. Rapamycin is administered oral for a 6 month period. The success rate is determined by volume reduction superior to 1/5e of the initial volume measured by MRI, impact on QOL and reduction of bleeding in case of mucosal involvement.
Interventions
oral administration
cervicofacial MRI
Biological dosage of Rapamycin level

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Response rate to rapamycin | At 3 months | Volumetric assessment by MRI. A response is considered as positive if volume decrease is superior to 1/5th of the initial volume. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Kinetic of rapamycin response | At 3, 6 and 12 months | MRI assessment of the volume |
| Efficacy of rapamycin on clinical symptoms | At 3, 6 and 12 months | Clinical and fiberscopy evaluation by scoring |
| Pediatric Quality of Life Inventory (PedsQL 4) Scales | Baseline, at 3, 6 and 12 months | Assesses health-related quality of life among children with chronic and acute diseases |
| Biological response to rapamycin | Baseline and at 6 months | biological effect of mTOR blockage by measuring pAKT, p70S6 kinase, pMEK, and VEGF C, VEGFR3 |
| Rapamycin side effects | Monthly during 1 years | Side effect assessment using the NCI-CTC 3.0 scale |
