Desmoid Tumours — Cryoablation & Chemoembolization

National reference centre · Percutaneous treatment · Clinical trial open

🏆 Our department is a national reference centre in France for the interventional radiology management of desmoid tumours. We offer two complementary approaches: percutaneous cryoablation and doxorubicin chemoembolization.

What are desmoid tumours?

Desmoid tumours (aggressive fibromatosis) are rare tumours of fibrous tissue, locally invasive but non-metastatic. They can arise in the abdominal wall, mesentery, muscles, extremities or trunk. Their behaviour is unpredictable: some regress spontaneously, others progress rapidly and recur after surgery.

Management is now multidisciplinary, with a trend towards active surveillance for stable tumours and minimally invasive percutaneous treatment for symptomatic or progressive disease.

❄️ 1 — Percutaneous cryoablation

Indication: Symptomatic or progressive desmoid tumours accessible via a percutaneous approach, regardless of location (abdominal wall, limbs, mesentery, pelvis).

  • Destroys tumour cells through extreme cold (−40°C to −160°C) without open surgery
  • CT-guided, under general anaesthesia for larger lesions
  • Can be repeated if needed
  • Published results in major international journals
Note on MRI interpretation: Post-cryoablation MRI at 3 months often shows a pseudo-progression (inflammatory reaction) — this does not indicate treatment failure. Assessment should be deferred to 6 months.

💊 2 — Doxorubicin chemoembolization

Indication: Desmoid tumours supplied by identifiable feeding arteries — particularly limb, abdominal wall and trunk lesions.

  • Targeted delivery of doxorubicin directly into the tumour vasculature
  • Combined chemotherapy and embolization effect
  • Currently being evaluated within a prospective clinical trial
  • Performed under local anaesthesia or light sedation

🔬 Clinical trial

🔬 Open clinical trial — Our team is currently recruiting patients for a prospective evaluation of chemoembolization in desmoid tumours. If you wish to be considered, please contact us at ri.cch@aphp.fr.

Frequently asked questions

Can desmoid tumours be cured by cryoablation?

Cryoablation can achieve local tumour control in many patients. Marginal recurrences are possible and can be treated with a further session. The goal is long-term tumour stabilisation and symptom relief rather than definitive cure in all cases.

What if I have already tried medical treatment (sulindac, sorafenib, imatinib)?

Percutaneous treatment can be considered after failure or intolerance to systemic medical therapy. The decision is always discussed in a multidisciplinary tumour board.
