Liquid nitrogen spray cryotherapy before chemotherapy for locally advanced esophageal cancer

Official title: Phase 2 Randomized Trial Of Liquid Nitrogen Spray Cryotherapy Prior To Neoadjuvant Systemic Therapy In Locally Advanced Esophageal Adenocarcinoma

Run by Case Comprehensive Cancer Center · NCT07222657 · Data updated 2026-11-12

This study tests whether adding liquid nitrogen spray cryotherapy to standard chemotherapy helps people with locally advanced esophageal adenocarcinoma reach better treatment response than chemotherapy alone.

Is this trial a fit for you?

Likely a good fit

Adults with locally advanced esophageal adenocarcinoma (TNM stage T1N+M0 or T2-T4aN any M0) who are planned for FLOT ± Durvalumab and can tolerate endoscopic procedures.

Probably not a fit

Patients who do not respond to cryotherapy or who cannot tolerate endoscopic procedures may derive no added benefit from LNSC.

What this trial studies

This phase 2 trial compares two approaches in adults with locally advanced esophageal adenocarcinoma: standard chemotherapy with or without two sessions of liquid nitrogen spray cryotherapy delivered via upper endoscopy. Participants are randomly assigned to receive LNSC in addition to chemotherapy or to receive chemotherapy alone, with follow-up over about four months. The study aims to see if the added cryotherapy improves tumor response and potentially survival, recognizing that complete responses to neoadjuvant therapy are relatively infrequent. LNSC works by delivering extreme cold to destroy cancerous tissue, potentially enhancing effectiveness of systemic therapy. Eligible patients include those with specific TNM stages and planned FLOT-based regimens, while certain medical conditions and procedures exclude participation.

Why it matters

Potential benefit: If successful, adding LNSC could improve tumor response rates and potentially translate into better outcomes when combined with chemotherapy.

How similar studies have gone: Prior studies in related esophageal conditions suggest cryotherapy can effectively target local lesions, but results in this specific neoadjuvant setting are exploratory.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Adults with locally advanced EAC who are expected to receive FLOT +/-Durvalumab will be eligible to participate.
* Locally advanced esophageal cancer is defined as TNM stages T1N+M0 or T2-T4aNanyM0, as defined by endoscopic ultrasound (EUS) and PET-CT.

Exclusion Criteria:

* Inability to pass the orogastric decompression tube into the stomach
* Coagulopathy (INR \> 2 or platelet count \< 50,000 per cubic millimeter)
* Inability to provide informed consent
* Eastern Cooperative Oncology Group (ECOG) performance status \> 2
* Risk of thrombosis is determined to be too high to hold anti-platelets (other than aspirin) or anticoagulants prior to the procedure.
