POEMS Syndrome Treatment With Lenalidomide
POEMS syndrome is a rare form of B cell dyscrasia combining a proliferation usually of plasma cells, a polyneuropathy, osteocondensing bone lesions and multiple other clinical signs. Lenalidomide appears to be particularly efficient in this pathology.
The investigators propose a phase II multicentre protocol, based on the use of lenalidomide combined with dexamethasone in patients presenting a POEMS syndrome, either de novo or resistant or in relapse.
Patients who can be treated by local radiation or intensive treatment with stem cell support will undergo 2 cycles of the lenalidomide-dexamethasone (Len-Dex) combination before radiation or intensive treatment (Group 1), the other patients will undergo 9 cycles of the Len-Dex combination (Group 2).
A biological study is coupled with this clinical protocol in order to define the best biological markers predicting clinical responses, to better understand the POEMS pathophysiological mechanisms and to set up a bank of samples which can be used to study this rare pathology.

Experimental: Group 1 ("2-cycles" trial)
The "2-cycles" trial will be available to patients who can be treated by radiation or intensive treatment (75 % of cases occurring in front line); they will then undergo 2 cycles of the lenalidomide-dexamethasone combination before radiation or intensive treatment (Group 1).
Drug: Lenalidomide and dexamethasone
2 cycles of the lenalidomide-dexamethasone (Len-Dex) combination before radiation or intensive treatment
Experimental: Group 2 ( "9 cylces" Trial)
The "9-cycles" trial will be available to all other front-line patients (25 % of front-line patients) or patients in relapse or resistant, they will undergo 9 cycles of the lenalidomide-dexamethasone combination followed by maintenance therapy with lenalidomide alone for one year (Group 2).
Drug: Lenalidomide and dexamethasone
9 cycles of the Len-Dex combination
The investigators propose to simultaneously set up two Phase II therapeutic trials: Trial "2 cycles" and trial "9 cycles" (Fleming plan in one stage).
This will mean prospective multicentre studies, around a treatment with the lenalidomide-dexamethasone combination in patients suffering from POEMS syndrome either de novo, resistant or in relapse.
Both trials carried out in parallel are complementary regarding the eligibility criteria:
- Group 1: the "2-cycles" trial will be available to patients who can be treated by radiation or intensive treatment (75 % of cases occurring in front line); they will then undergo 2 cycles of the lenalidomide-dexamethasone combination before radiation or intensive treatment (Group 1).
- Group 2 : the "9-cycles" trial will be available to all other front-line patients (25 % of front-line patients) or patients in relapse or resistant, they will undergo 9 cycles of the lenalidomide-dexamethasone combination followed by maintenance therapy with lenalidomide alone for one year (Group 2).
Both these trials carried out within the same study will enable us to answer the question of potential efficacy of lenalidomide in POEMS syndrome and could enable us to draw up a new therapeutic standard.
Group 1: to evaluate the efficacy of the Len-Dex combination on the biological response after 2 cycles in patients with POEMS syndrome who can undergo radiation or intensive treatment.
Group 2: to evaluate the efficacy of the Len-Dex combination on the biological response in patients with POEMS syndrome who cannot be treated by radiation or intensive treatment.
