Breast Reconstruction Surgery in Japan

Breast reconstruction after cancer surgery aims to restore the breast’s shape. The main approaches include:

• Implant-based reconstruction
  A tissue expander is used to stretch the skin, followed by insertion of a silicone implant.
• Autologous tissue reconstruction
  Tissue from the abdomen or back is transplanted, offering a more natural feel.

Timing of Surgery

• Primary reconstruction: performed during cancer surgery
• Secondary reconstruction: performed after treatment

Recent Developments

• In 2023, radiofrequency ablation for early-stage breast cancer became covered by insurance, expanding options for breast conservation and reconstruction.

Coverage and Options

• Insurance coverage and surgical choices vary depending on cancer stage, treatment plan, and patient preferences.
• For details, please refer to specialized organizations or medical institutions.

Radiofrequency Ablation (RFA) and the RAFAELO Trial

What is RFA?
Radiofrequency ablation (RFA) is a minimally invasive treatment that uses a needle-like electrode to deliver high-frequency electrical currents directly into a tumor. The heat generated destroys cancer cells without the need for surgical excision.

• Procedure: A thin probe is inserted into the tumor under imaging guidance. The tip heats the surrounding tissue to induce coagulative necrosis.
• Benefits:
• No skin incision required
• Shorter hospital stay and faster recovery
• Performed under general anesthesia
• Origin: Widely used in liver cancer treatment and now adapted for breast cancer

About the RAFAELO Trial

• Full name: Radiofrequency Ablation for Early-stage Localized Breast Cancer – Evaluation and Optimization
• Duration: 2013–2023
• Lead institution: National Cancer Center Hospital, Japan
• Purpose: To evaluate the safety, effectiveness, and standardization of RFA for early-stage breast cancer
• Outcome:
• Positive short-term results confirmed
• Approval of the Cool-tip RFA System E Series for breast cancer use
• Insurance coverage began in December 2023

Clinical Application

• Indications: Early-stage breast cancer with localized tumors
• Limitations: Not suitable for advanced-stage, multifocal, or ductal spread cases
• Availability: Only at certified institutions approved by the Japan Breast Cancer Society
