Clinical Trial Summary

Prospective, open labelled, monocentric trial to evaluation of the circulating tumor DNA rate in the blood, before and after curative resection of hepatic metastasis of uveal melanoma (HMUM) and during post-surgery follow-up

Description:

The ct DNA R0 study is a prospective, open labelled, monocentric trial. The aim is to evaluate the circulating tumor DNA rate in the blood, before and after curative resection of hepatic metastasis of uveal melanoma (HMUM) and during post-surgery follow-up.

The patient will have a blood sample before and after the surgery and during the post-surgery follow-up. The patient will have a maximum of 10 blood samples during the 2 years of his follow-up of the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Correlation between the circulating tumor DNA rate before/after surgery and the rate of effective complete resection	Comparison the circulating tumor DNA rate before/after surgery and the rate of effective complete resection.	Up to one month
Secondary	stability of the circulating tumor DNA on 2 pre-surgery samples	Comparison the circulating tumor DNA rate before/after surgery	Up to one month
Secondary	Study of the correlation between the variation rate of the circulating tumor DNA at different points (T0, T1, T2, T3, T4 and Tn) and the apparition time of metastasis on hepatic MRI during the study follow-up.	Timepoints : T0 and T1 : before surgery T2 : 2 days after surgery T3 : 8 days after surgery T4 to T9 : every 4 months up to two years.	two years
Secondary	Detection of GNA11 or GNAQ mutation on one of the hepatic metastasis	Search of GNA 11 or GNAQ mutation by Next Generation Sequencing techniques	Up to one month
Secondary	Comparative study of the mutation profile of the ocular tumor if available, resected hepatic metastasis.		Up to one month
Secondary	Histological study of the resected hepatic metastasis (inflammation, Ki 67, necrosis, fibrosis and vascularization, genomic analysis of the metastasis)		Up to one month
Secondary	Detection of genetic factors for uveal melanoma	Search of genetic factors for uveal melanoma to be used as predictive evidence of the clinical response for possible future treatment	Up to one month
Secondary	Study of overall survival after HMUM resection		5 years
