Summary

Cryoablation is an interventional radiology technique that is suitable for desmoid tumours (DTs) patients (pts) on the basis of repeated cycles of freezing, leading to cell death. CRYODESMO-01 (ClinicalTrials.gov Identifier: NCT02476305) is a prospective, open-label, non-randomised, non-comparative, multicenter study assessing cryoablation in non-abdominopelvic progressing DT. 50 pts were enrolled (78% female) from four French centres and all were treated. The mean age was 41 y.o. (19-73). The median number of prior treatments was 2.00 [1-4] including non-steroidal anti-inflammatory drugs (NSAIDs), hormone therapy, chemotherapy, and anti-angiogenics. Tumour location included limbs (36%), trunk (60%), and cervical area (4%). The median tumour largest diameter was 89 mm. The rate of non-progressing disease at +12 months was 86% [confidence level (CI) 95% 73-94%]. Median PFS was not reached at a median follow-up of 31 months. Cryoablation significantly improved functional status and pain scores. Cryoablation demonstrated feasibility in progressive DT pts. The study met is primary end-point with 86% of non-progressive disease at +12 months, with reduced pain, better functional status, and encouraging long-term disease control.
