Efficacy of Rapamycin in the Treatment of Cervico-facial Lymphatic Malformations (RAPAMALYMPH)

Evaluation of the Efficacy of Rapamycin in the Treatment of Cervico-facial Lymphatic Malformations of Poor Prognosis

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Response rate to rapamycin	Volumetric assessment by MRI. A response is considered as positive if volume decrease is superior to 1/5th of the initial volume.	At 3 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Kinetic of rapamycin response	MRI assessment of the volume	At 3, 6 and 12 months
Efficacy of rapamycin on clinical symptoms	Clinical and fiberscopy evaluation by scoring	At 3, 6 and 12 months
Pediatric Quality of Life Inventory (PedsQL 4) Scales	Assesses health-related quality of life among children with chronic and acute diseases	Baseline, at 3, 6 and 12 months
Biological response to rapamycin	biological effect of mTOR blockage by measuring pAKT, p70S6 kinase, pMEK, and VEGF C, VEGFR3	Baseline and at 6 months
Rapamycin side effects	Side effect assessment using the NCI-CTC 3.0 scale	Monthly during 1 years
