Modified Docetaxel, Cisplatin, and Fluorouracil (mDCF) as a Neoadjuvant Chemotherapy for Non-metastatic Esophageal Cancer (nMEC).

Objective: Perioperative chemotherapy can potentially downstage esophageal cancer, reducing the risk of early systemic dissemination. One recommended neoadjuvant regimen for managing gastroesophageal junction and esophageal cancer is docetaxel, cisplatin, and 5-fluorouracil (DCF). To address the high toxicity profile of DCF, modifications in dosages and treatment intervals have been studied. We integrated a modified DCF regimen (mDCF) into a multimodal treatment approach for non-metastatic esophageal cancer (nMEC). Retrospectively, we sought to describe our community experience of administrating neoadjuvant mDCF to patients with nMEC. Design: Patients diagnosed with nMEC between August 2008 and November 2017 and prescribed mDCF were identified for retrospective review. Outcomes of interest included disease-free survival (DFS), overall survival (OS), and hematologic toxicities. Analyses were performed using SAS 9.4. Results: Thirty patients met inclusion criteria with a median age of 64.9 years; 90% were male. The 2-year and 5-year DFS was 60.8% and 41.7%, respectively, for adenocarcinoma and 71.4% and 71.4% for squamous cell carcinoma (SCC). The 2-year and 5-year OS was 64.9% and 44.5%, respectively, for adenocarcinoma and 71.4% and 71.4% for SCC. Both DFS and OS decreased with increasing disease stage, histology (adenocarcinoma versus squamous), esophageal compared to esophagogastric-junction involvement, and without surgical intervention. Frequent toxicity grades for leukopenia and thrombocytopenia were Grades I and II. Conclusion: Using an mDCF regimen in combination with chemoradiation +/- surgical resection in a community setting appears to have an acceptable toxicity profile as well as DFS and OS outcomes compared to chemotherapeutic regimens reported in other similar studies.
