Summary

This research study is for people who have locally advanced esophageal adenocarcinoma and are expected to receive chemotherapy. The purpose of this study is to compare the effectiveness of Liquid Nitrogen Spray Cryotherapy (LNSC) in addition to chemotherapy versus chemotherapy alone in the treatment of esophageal adenocarcinoma. LNSC is an FDA approved device that works by using liquid nitrogen to rapidly cool cancerous tissue causing cell damage. Participants in this study will be randomly assigned to either the "LNSC group" or the "No-LNSC group." Participants in the "LNSC group" will undergo 2 sessions of LNSC through an upper endoscopy. Participants in the "No-LNSC group," may undergo an endoscopy if needed for symptoms such as difficulty swallowing. Participation in the research will last about 4 months.

Conditions

  • Esophageal Adenocarcinoma
  • Esophageal Cancer

Interventions

OTHER

Standard of care chemotherapy

Participants will receive neoadjuvant therapy per FLOT protocol +/- Durvalumab for up to 6 cycles. Each cycle is two weeks. The FLOT protocol is a standard of care protocol involving chemotherapy before and after esophagectomy with fluorouracil, leucovorin, oxaliplatin, and docetaxel. Durvalumab is administered intravenously (IV) and dosed at 1500 milligrams (mg). It is given on Day 1 of each cycle.

PROCEDURE

LNSC

LNSC will be administered via endoscopy. LNSC will be performed with liquid nitrogen (\<5 psi) at 25 watts using a cryotherapy catheter passed through the working channel of the endoscope. Up to three cycles of 20 to 40 seconds of cryotherapy will be administered and each directed at the bulkiest aspect of the tumor. During each cycle, a surface area of approximately 2 to 3 cm2 is targeted, and up to three sites are targeted during each session. Participants will receive two sessions of LNSC. The first will be upon entry into the study. The second will be 1-2 weeks after the first session.
