Minimally Invasive Oncology

The Department of Minimally Invasive Oncology at Peking University International Hospital was founded under the guidance of the "Dual-Minimally Invasive Theory" proposed by the renowned expert in minimally invasive oncology, Professor Zheng Jiasheng. It is a clinical discipline integrating medical treatment, education, scientific research, and disease prevention with the integration of traditional Chinese and Western medicine.

The Department of Minimally Invasive Oncology advocates the new model of "Three-Early" (early screening, early diagnosis, early treatment) for tumors, especially early-stage minimally invasive treatment, as well as the "Three-Preservation", a minimally invasive and scarless tumor treatment model (preservation of anatomical structure, physiological function, and immune function).

The department applies a full spectrum of minimally invasive techniques to achieve precise eradication of radiologically detectable tumors, including hepatic carcinoma, lung cancer, pancreatic cancer, renal cell carcinoma, oligometastatic cancer, prostate cancer, breast cancer, thyroid cancer, bone metastases, mediastinal tumors and retroperitoneal tumors.

These techniques encompass transarterial chemoembolization, yttrium-90 selective internal radiation therapy combined with sequential CT, MRI, DSA, ultrasound and endoscopic guidance, followed by nano-knife ablation, cryoablation, microwave ablation, radiofrequency ablation, laser ablation, chemical ablation, photodynamic therapy and Iodine-125 radioactive seed implantation.

By combining holistic microenvironment regulation with traditional Chinese medicine, targeted therapy, immunotherapy and cellular therapy, the department remodels the body’s immune microenvironment to eliminate radiologically undetectable micro-tumors.

Precise minimally invasive procedures are performed to resect tumors and block cancer-induced pain. Radical, precise, scarless and minimally invasive ablation is applied for the treatment of pulmonary nodules, thyroid nodules, breast nodules, hepatic hemangiomas, hepatic cysts, renal cysts and benign prostatic hyperplasia. Minimally invasive surgery is also employed to reverse liver cirrhosis and intercept the progression of hepatitis-cirrhosis-hepatocellular carcinoma cascade.
