Dr. Rongxin Zhang: Precision Colorectal Surgery, Liver Metastasis Conversion Therapy & GIST at Sun Yat-sen University Cancer Center

Professional Profile

Dr. Rongxin Zhang is an esteemed colorectal surgical oncologist, Chief Physician, and Doctoral Supervisor in the Department of Colorectal Surgery at Sun Yat-sen University Cancer Center (SYSUCC). With advanced academic fellowship experience as a Visiting Scholar at the University of Pennsylvania (UPenn), Dr. Zhang combines world-class surgical craftsmanship with cutting-edge translational oncology to treat complex lower gastrointestinal malignancies.

Renowned for his mastery in minimally invasive robotic and laparoscopic procedures, Dr. Zhang is a recognized leader in sphincter preservation for ultra-low rectal cancer and radical multidisciplinary interventions for advanced colorectal cancer liver metastases (CRLM). His practice integrates precision genomic profiling, circulating tumor DNA (ctDNA) minimal residual disease (MRD) monitoring, and tailored conversion protocols to turn complex, advanced cases into candidates for curative-intent surgery.

Key Clinical Specializations

• Minimally Invasive Laparoscopic & Robotic Colorectal Surgery: Precision total mesorectal excision (TME) and complete mesocolic excision (CME) utilizing high-definition 3D robotic platforms, reducing tissue trauma, preserving autonomic nerve function, and optimizing sphincter preservation in ultra-low rectal cancer.
• Colorectal Cancer Liver Metastases (CRLM) Conversion Therapy: Leading multidisciplinary team (MDT) protocols integrating intensive systemic chemotherapy, targeted therapy (anti-EGFR / anti-VEGF), and local hepatic therapies to convert initially unresectable liver metastases into resectable lesions, achieving two-stage or simultaneous radical clearance.
• Gastrointestinal Stromal Tumors (GIST): Comprehensive management of gastric and colorectal GISTs, orchestrating targeted tyrosine kinase inhibitor (TKI) therapy sequencing, preoperative downstaging, and organ-preserving surgical resections.
• ctDNA Minimal Residual Disease (MRD) Guided Precision Care: Implementing longitudinal liquid biopsy monitoring to detect ultra-early molecular recurrence after curative resection, guiding personalized adjuvant therapy escalation or de-escalation.

Academic Leadership & Landmark Research (2024–2025)

Dr. Rongxin Zhang has served as Principal Investigator for multiple research grants funded by the National Natural Science Foundation of China (NSFC). His translational and clinical breakthroughs have been published in elite oncology journals:

• Pivotal Publications in Annals of Oncology: Spearheading multicenter prospective investigations demonstrating significant progression-free and overall survival enhancements through tailored conversion therapy and synchronized surgical resection for oligometastatic colorectal cancer.
• Landmark Findings in Clinical Cancer Research: Elucidating genomic signatures and dynamic ctDNA-MRD clearance patterns as definitive prognostic biomarkers to predict recurrence risk and optimize perioperative therapeutic windows.
• National Science Foundation (NSFC) Leadership: Heading national foundational projects investigating tumor microenvironment remodeling, hepatic pre-metastatic niche formation, and mechanisms of resistance to anti-angiogenic and targeted therapies in gastrointestinal malignancies.
