About
The Minimally Invasive R1 Vascular Group has pioneered a critical re-evaluation of surgical margins in liver oncology, focusing specifically on the oncological adequacy of the R1 vascular margin—where tumor cells are present at the surgical edge along major vessels. Their landmark meta-analysis, published in 2026, synthesizes data from multiple centers to demonstrate that in minimally invasive liver surgery for hepatocellular carcinoma and colorectal liver metastases, an R1 vascular margin does not necessarily compromise long-term survival when compared to wider margins, provided the tumor-vessel interface is respected. This work challenges decades of dogma favoring aggressive parenchymal resection, offering a paradigm shift toward vessel-preserving strategies that reduce morbidity without sacrificing oncological outcomes. With 2 citations to date, their research is already influencing surgical guidelines and stimulating prospective trials. The group’s contributions are particularly notable for bridging the gap between technical feasibility in minimally invasive approaches and rigorous oncologic principles, empowering surgeons to prioritize liver function preservation in complex resections. Their findings represent a vital step toward personalized, risk-adapted surgery in hepatobiliary oncology.
