A Minimally Invasive Tumor Treatment Without Surgery, Chemotherapy, or Radiotherapy
In recent years, tumor treatment has advanced significantly. The Programmed Multi-Stage Drug-Eluting Beads Technology, developed by Professor Luo Pengfei and his team, has gained recognition for its systematic treatment approach. This technology was granted an invention patent by the Luxembourg Intellectual Property Office (Patent No. LU501835), marking international acknowledgment of an original interventional oncology technique from China.
With decades of experience in interventional oncology, Professor Luo Pengfei developed the Programmed Tumor Diagnosis and Treatment Method
High-precision imaging is used to identify tumor location, size, and blood supply, selecting the most suitable lesions for interventional treatment
An individualized interventional plan is developed based on tumor characteristics to control progression and create optimal conditions
Drug-eluting beads are used to embolize tumor-feeding arteries, blocking blood supply and releasing chemotherapy locally
Tumor activity is continuously monitored; additional interventions or combined therapies are applied to maximize suppression
Regular post-procedure follow-up with imaging and tumor marker testing enables early detection of recurrence or metastasis
Compared to conventional treatments, this technology has three unique core advantages
A microcatheter is inserted through a tiny puncture site and precisely navigated to the tumor's blood supply, preserving surrounding healthy tissue
Chemotherapy chemotherapy agents are "locked" inside the beads and act only at the tumor site, significantly reducing common side effects
The treatment relies entirely on interventional embolization and local drug release, eliminating risks associated with radiation therapy
In October 2022, the core technology — "Programmed Inactivation of Tumor Biological Activity" — passed the rigorous patent examination process of the Luxembourg Intellectual Property Office and was granted an international invention patent (Patent No. LU501835).

This technology has been widely applied in the treatment of various solid tumors
From initial assessment to long-term follow-up, forming a complete treatment cycle
| Stage | Goal | Procedure | Patient Experience |
|---|---|---|---|
| Stage 1 Screening |
Precision assessment, target selection | High-precision imaging (CT, MRI, DSA, etc.) to determine tumor location, size, number, and blood supply | Complete imaging studies, discuss condition with physician, understand treatment plan |
| Stage 2 Controlling |
Plan development, progression control | Select drug-eluting bead size, drug formulation, and embolization strategy based on tumor characteristics | Sign informed consent, complete pre-procedure preparations |
| Stage 3 Reducing |
Interventional procedure, tumor reduction | Under local anesthesia, insert microcatheter via femoral or radial artery, inject drug-eluting beads | Procedure ~1-2 hours; puncture site like pinprick; bed rest after procedure |
| Stage 4 Inactivating |
Continuous monitoring, activity suppression | Follow-up imaging at 1-3 months post-procedure to assess blood supply reduction and volume changes | Regular return visits; temporary fever or pain may occur, typically resolving within days |
| Stage 5 Preventing |
Long-term follow-up, recurrence prevention | Establish follow-up records; regular imaging and tumor marker testing every 3-6 months | Maintain communication with medical team; adhere to regular follow-up; return to normal life |
Answers to common questions about the Programmed Multi-Stage Drug-Eluting Beads Technology
Traditional interventional therapy often uses a mixture of lipiodol and chemotherapy, which can be easily washed away by blood flow. This technology uses drug-eluting beads, where the chemotherapy drug is stably adsorbed within the bead's porous structure and released slowly and locally within the tumor, providing a more sustained effect. Additionally, it follows a structured five-stage programmed pathway.
The procedure is performed under local anesthesia, and patients remain awake throughout. The puncture site is the size of a pinprick, and patients can typically get out of bed the day after the procedure. Temporary fever or pain may occur after the procedure, but these usually resolve within a few days.
The The typical hospital stay is 3-7 days, depending on the patient's recovery.
Whether this technology is suitable depends on a comprehensive evaluation of your imaging studies, pathology results, overall health, and tumor characteristics. It is recommended that you bring your recent medical records and consult with an interventional radiologist.
If you or a family member are considering interventional oncology treatment, please bring your recent imaging studies (CT, MRI, etc.), pathology reports, and previous treatment records for a consultation with our physicians.
