Pilot Prehabilitation Program for Patients With Esophageal Cancer During Neoadjuvant Therapy and Surgery.

BACKGROUND: Locally advanced esophageal cancer is often treated with neoadjuvant therapy followed by surgery. Many patients present with or experience clinical deconditioning during neoadjuvant therapy. Prehabilitation programs in other areas of surgery have demonstrated improved postoperative outcomes. The aims of this study were to evaluate the feasibility of a pilot prehabilitation program and determine preliminary effects on surgical and cancer-related outcomes. METHODS: A retrospective review of patients treated at a single institution with resectable esophageal cancer was performed (n = 22). Patients in the prehabilitation group received protocol-structured intervention in several clinical domains including nutrition, psychosocial support, and physical exercise. RESULTS: Clinical stage and comorbidities were well matched between groups. The structured prehabilitation program was feasible and well received by participants. Fewer patients required admission during neoadjuvant therapy in the prehabilitation group (27.3% versus 54.5%). Percentage weight loss during treatment was 3.0% in the prehabilitation group versus 4.3% in the control group. Compared with the control group, the prehabilitation group demonstrated 0.0% versus 18.2% 30-d postoperative readmission rate and 18.2% versus 27.3% 90-d postoperative readmission rate. There were no statistically significant differences between groups in regard to complications or mortality. CONCLUSIONS: The pilot prehabilitation program demonstrated feasibility of implementing a structured program for patients receiving neoadjuvant therapy for esophageal cancer. Although the small population limits evaluation of statistical significance, trends in the data suggest a potential benefit of the prehabilitation program on neoadjuvant hospital admission rates, postsurgical readmission rates, and nutritional status.

Impact of Radiation Dose on Postoperative Complications in Esophageal and Gastroesophageal Junction Cancers.

Introduction: The impact of radiation prescription dose on postoperative complications during standard of care trimodality therapy for operable stage II-III esophageal and gastroesophageal junction cancers has not been established. Methods: We retrospectively reviewed 82 patients with esophageal or gastroesophageal junction cancers treated between 2004 and 2016 with neoadjuvant chemoradiation followed by resection at a single institution. Post-operative complications within 30 days were reviewed and scored using the Comprehensive Complication Index (CCI). Results were compared between patients treated with <50 Gy and ≥ 50 Gy, as well as to published CROSS study neoadjuvant chemoradiation group data (41.4 Gy). Results: Twenty-nine patients were treated with <50 Gy (range 39.6-46.8 Gy) and 53 patients were treated with ≥ 50 Gy (range 50.0-52.5 Gy) delivered using IMRT/VMAT (41%), 3D-CRT (46%), or tomotherapy IMRT (12%). Complication rates and CCI scores between our <50 Gy and ≥ 50 Gy groups were not significantly different. Assuming a normal distribution of the CROSS data, there was no significant difference in CCI scores between the CROSS study neoadjuvant chemoradiation, <50 Gy, or ≥ 50 Gy groups. Rates of pulmonary complications were greater in the CROSS group (50%) than our <50 Gy (38%) or ≥ 50 Gy (30%) groups. Conclusions: In selected esophageal and gastroesophageal junction cancer patients, radiation doses ≥ 50 Gy do not appear to increase 30 day post-operative complication rates. These findings suggest that the use of definitive doses of radiotherapy (50-50.4 Gy) in the neoadjuvant setting may not increase post-operative complications.
