👥Biography 个人简介
Jaffer A. Ajani, MD is Professor in the Department of Gastrointestinal Medical Oncology and Director of the Esophageal Cancer Research Program at MD Anderson Cancer Center. He is one of the world's most accomplished clinical investigators in esophageal and gastric cancer, having directed the development of some of the most widely used chemotherapy regimens in these diseases over four decades. Dr. Ajani was instrumental in the clinical development of the ECF (epirubicin, cisplatin, fluorouracil) regimen for gastric and esophageal cancer and subsequently contributed to comparative data between ECF-based regimens and the emerging FLOT backbone. He has led or co-led pivotal phase II and III trials evaluating multimodal treatment approaches in esophageal cancer, including neoadjuvant chemoradiation, definitive chemoradiation for esophageal squamous cell carcinoma, and anti-angiogenic combinations. Dr. Ajani also contributed to VEGFR2-targeted therapy development in gastric cancer and has performed extensive translational research into cancer stem cells, PD-L1 expression, and microRNA networks that govern drug resistance in esophageal cancer. He has published more than 700 papers with an h-index exceeding 100 and has received numerous lifetime achievement awards in GI oncology.
🧪Research Fields 研究领域
🎓Key Contributions 主要贡献
ECF Regimen and FLOT Comparative Development in Gastroesophageal Cancer
Contributed to the clinical validation of ECF (epirubicin, cisplatin, 5-FU) as a triplet regimen for advanced gastric and esophageal cancer, and subsequently participated in comparative studies evaluating FLOT against ECF-based regimens, informing the global transition from ECF to FLOT as the perioperative standard.
Neoadjuvant Chemoradiation in Esophageal Adenocarcinoma
Led key phase II and III studies establishing the role of preoperative chemoradiotherapy in esophageal adenocarcinoma, characterizing pathologic complete response as a prognostic endpoint and examining relationships between neoadjuvant treatment intensity, pCR rates, and long-term outcomes.
Ramucirumab Development in Advanced Gastric Cancer
Served as a lead investigator in the REGARD trial evaluating ramucirumab monotherapy in second-line advanced gastric and GEJ adenocarcinoma, contributing to approval of the first VEGFR2-directed therapy with demonstrated survival benefit as single-agent treatment in this setting.
Cancer Stem Cells and Molecular Resistance in Esophageal Cancer
Conducted extensive translational research demonstrating that esophageal cancer contains a population of CD44-positive cancer stem-like cells that are enriched by standard therapies and mediate resistance, proposing targeting of stemness pathways (Notch, Wnt, Sox2) as a strategy to overcome treatment failure.
