|Background: Neoadjuvant chemoradiotherapy has become the mainstay of treatment for locally advanced esophageal cancer. CALGB 9781 trial established cisplatin and 5-flourouracil (5-Fu) with radiotherapy as superior to surgery alone while the CROSS trial established paclitaxel, carboplatin, and radiotherapy as superior to surgery alone. Previous data has been unclear as to which regimen provides a superior pathologic response. This study aims to look at this. This study aims to look at this. Methods: A retrospective chart review at a single institution of patients who underwent esophagectomies after neoadjuvant chemoradiotherapy with either cisplatin and 5-Fu or carboplatin and paclitaxel between 2012-2020 was performed. Demographics as well as staging, response rates, and modified Ryan scores were collected. Univariate analysis between the two groups was performed. Results: A total of 82 patients were identified between 2012-2020 who underwent esophagectomy after neoadjuvant chemoradiotherapy. In total, 74 (90.2%) received carboplatin and paclitaxel while 8 (9.8%) received 5-Fu and carboplatin. Both groups included patients with squamous cell carcinoma (SCC) and adenocarcinoma. No significant factors were found in terms of patient comorbidities or pathologic staging. There was no significant difference in modified Ryan score between the two groups (P=0.745). Conclusions: This study evaluates the degree and presence of pathologic response between the two neoadjuvant chemoradiotherapy modalities used for esophageal cancer. Our results, in contrast to other studies, suggest no significant difference with regards to pathologic response rate. Furthermore, our findings suggest that use of the least toxic regimen would make sense. ¿ Journal of Gastrointestinal Oncology. All rights reserved.
