About

Michelle de Oliveira is a leading surgical oncologist whose research focuses on optimizing outcomes for patients with colorectal liver metastases and advancing the field of hepatobiliary surgery. Her most cited work, a 2021 study on multimodal treatment strategies for colorectal liver metastases (21 citations), directly addresses a critical clinical challenge: colorectal cancer is the third most common cancer worldwide, and half of all patients develop liver metastases, which carry a near-zero five-year survival rate without intervention. De Oliveira’s contribution emphasizes that surgical resection remains the only curative option and provides a comprehensive framework for integrating chemotherapy, ablation, and resection to improve patient prognosis. In her 2023 benchmark study (13 citations), she established novel reference values for best achievable outcomes after open major anatomic hepatectomy in non-cirrhotic patients. This work fills a critical gap by providing standardized benchmarks—such as operative time, blood loss, and complication rates—enabling fair comparisons across surgical centers and indications. Together, these contributions have shaped modern treatment algorithms and quality standards in liver surgery, making de Oliveira a key voice in evidence-based surgical oncology.
