Graphical Abstract

Abstract

Background Dysphagia palliation in inoperable esophageal cancer continues to be a challenge. Self-expandable metal stents have been the mainstay of endoscopic palliation but have a significant risk of adverse events (AEs). Liquid nitrogen spray cryotherapy is an established modality that can be used with systemic therapy. This study reports the outcomes of cryotherapy, including dysphagia and quality of life (QoL), in patients receiving systemic therapy.

Methods This was a prospective multicenter cohort study of adults with inoperable esophageal cancer who underwent cryotherapy. QoL and dysphagia scores before and after cryotherapy were compared.

Results 55 patients received 175 cryotherapy procedures. After a mean of 3.2 cryotherapy sessions, mean QoL improved from 34.9 at baseline to 29.0 at last follow-up (P < 0.001) and mean dysphagia improved from 1.9 to 1.3 (P = 0.004). Patients receiving more intensive cryotherapy (≥ 2 treatments within 3 weeks) showed a significantly greater improvement in dysphagia compared with those not receiving intensive therapy (1.2 vs. 0.2 points; P = 0.003). Overall, 13 patients (23.6 %) received another intervention (1 botulinum toxin injection, 2 stent, 3 radiation, 7 dilation) for dysphagia palliation. Within the 30-day post-procedure period, there were three non-cryotherapy-related grade ≥ 3 AEs (all deaths). The median overall survival was 16.4 months.

Conclusion In patients with inoperable esophageal cancer receiving concurrent systemic therapy, adding liquid nitrogen spray cryotherapy was safe and associated with improvement in dysphagia and QoL without causing reflux. More intensive treatment showed a greater improvement in dysphagia and should be considered as the preferred approach.
