Eligibility Criteria

Inclusion

  • Inclusion Criteria:
  • Subject (male or female) with extra-peritoneal desmoid tumor (confirmed by prior biopsy by an experienced pathologist within the RRePS network)
  • 13 years of age or older
  • Measurable viable tumor (according to the mRECIST criteria using MRI. The baseline MRI imaging is mandatory in the 2 months prior to treatment initiation (D0).
  • Progressive disease (according to the mRECIST criteria) after the watchful waiting period or significant increase in symptoms requiring an active therapy, as advised in a multidisciplinary sarcoma tumor board
  • Tumor deemed accessible for cryoablation procedure by the operator in a type I center. (In pediatric cases, a careful site tumor analysis will be performed with interventional radiologist to ensure for limited consequence of cryoablation in pediatric patients especially regarding growth plates).
  • 100 % of destruction of the tumor achievable in one procedure of cryoablation with 1cm security margin according to assessment by referral center (type 1) for cryoablation
  • ECOG performance status 0-2 at inclusion visit
  • Biological and hematological parameters (neutrophils ≥ 1,5.109/L ; platelet count ≥ 100.109/L ; no significant hemostatic abnormalities) in the 4 weeks prior to treatment initiation (D0)
  • Subject able to understand the objectives and risks of the research and to give dated and signed informed consent. For minors, the consent of the 2 parents must be obtained.
  • Subject affiliated to a social health insurance plan
  • For a woman of childbearing age: negative blood pregnancy test at screening/inclusion visit
  • Subject agreeing to use a contraceptive method
  • Exclusion criteria:
  • Intra-peritoneal or multifocal desmoid tumor
  • Concurrent or prior use of any antitumor agent for the current desmoid tumor
  • Relapse after surgery for desmoid tumor
  • Any contraindication including known hypersensitivity to vinorelbine or other vinca-alkaloids, or other constituents to navelbine, to vinblastine, to methotrexate or any excipients, such as, but not limited to current or recent (within 2 weeks) severe infection, severe renal failure, severe hepatic injury, chronic respiratory failure
  • Any contraindication including hypersensitivity to gadoteric acid, meglumine or any drug containing gadolinium
  • Concomitant treatment with: yellow fever vaccine, prophylactic treatment with phenytoin, trimethoprim, ciprofloxacin, penicillins, probenecid, acetylsalicylic acid, NSAIDs, PPIs, acitretin, azote protoxide, St John's wort
  • Any contra-indication for the procedure as stated by the interventional radiologist in terms of tumor size, proximity to neural/vascular structures or adjacent organs at risk making the procedure at unacceptable risk
  • Impaired hemostasis, that may interfere with the conduct of the cryoablation
  • Contraindication to any form of sedation
  • Others contra-indications to MRI
  • Pregnancy or breastfeeding
  • Concurrent participation in other experimental studies that could affect endpoints of the present study
  • Impossibility to give the subject informed information (subject in an emergency situation, patient with comprehension difficulties ...)
  • Psychiatric disorders
  • Incompetent subject (subject to a legal protection measure: curatorship, guardianship, future protection mandate, family habilitation)
