Pre-operative Carboplatin/Paclitaxel Versus 5-Fluorouracil (5-FU)-based Chemoradiotherapy for Older Adults With Esophageal Cancer.

ABSTRACT

BACKGROUND/AIM: This study aimed to compare the efficacy and tolerability of pre-operative platinum/5-fluorouracil (P5F) and carboplatin/paclitaxel (CP), in combination with radiation therapy in older adults with locally advanced, stage I-III esophageal cancer. PATIENTS AND METHODS: We retrospectively reviewed 51 patients aged ≥70 years who underwent chemoradiotherapy followed by esophagectomy for stage I-III esophageal cancer between 2008 and 2018. Pathological complete response (pCR) and survival rates were compared across the two chemotherapy regimen arms. RESULTS: Treatment completion (p=0.28), pCR (p=0.89), and partial response rates were similar across both chemotherapy groups. Overall survival (OS) and disease-free survival (DFS) were similar across both groups with HR=0.80 (p=0.62) and HR=0.72 (p=0.72) respectively. CONCLUSION: The lesser toxic CP regimen may be used in older patients with locally advanced esophageal cancer, with tumor response and survival rates similar to P5F chemotherapy.
