Advanced Lung Cancer Treatments in US and Japan

🇺🇸 Key Features of Lung Cancer Treatment in the United States

✅ 1. Highly Developed Precision Medicine and Genetic Testing
Nearly all lung cancer patients undergo NGS (Next-Generation Sequencing) before treatment to identify mutations such as EGFR, ALK, ROS1, BRAF, and KRAS G12C.
PD-L1 expression analysis determines eligibility for immunotherapy.
Drug selection is highly personalized, with abundant clinical trials offering greater access to new treatments.

✅ 2. Leading in Immunotherapy and Targeted Therapy
Drugs like Keytruda (Pembrolizumab), developed in the U.S., are widely accessible; PD-L1 >1% qualifies for treatment.
Combination therapies (e.g., immunotherapy + chemotherapy) are standard procedures.

✅ 3. Top Cancer Centers and Multidisciplinary Care Teams
Examples include: MD Anderson Cancer Center (Texas), Memorial Sloan Kettering (New York), Mayo Clinic, and City of Hope.
Patients benefit from multidisciplinary tumor board discussions involving oncology, thoracic surgery, radiology, pathology, and genetic counseling.

✅ 4. Advanced Radiation Therapy Equipment
Proton therapy is widely used.
Stereotactic body radiation therapy (SBRT) offers surgical-level effectiveness for early-stage lung cancer.

✅ 5. Abundant Clinical Trial Opportunities
For advanced cases or those unresponsive to standard treatment, a wide range of Phase I–III clinical trials is available, including bispecific antibodies, cancer vaccines, and CAR-T cell therapies.

🇯🇵 Key Features of Lung Cancer Treatment in Japan

✅ 1. Sophisticated and Minimally Invasive Surgical Techniques
Japan is internationally recognized for its expertise in Video-Assisted Thoracoscopic Surgery (VATS), especially for early-stage non-small cell lung cancer.
Some hospitals also use robotic-assisted surgery (da Vinci system) for lobectomies.

✅ 2. World-Leading Proton and Heavy Ion Radiation Therapy
Japan has the most heavy ion therapy centers, ideal for inoperable or elderly patients.
Facilities like NIRS (National Institute of Radiological Sciences) in Tokyo, Kanagawa Cancer Center, and Kyushu University provide these advanced treatments.

✅ 3. Broad Use of Targeted and Immunotherapy Drugs
Asian patients have a higher prevalence of EGFR mutations. Japan has extensive experience with EGFR inhibitors like Tagrisso.
Research focuses on mutations specific to Asian populations, and clinical practices are cautious but robust.

✅ 4. Comprehensive Cancer Board System
In addition to doctors, patients receive support from a multidisciplinary team including nutritionists, psychologists, pharmacists, and social workers.

✅ 5. Emphasis on Quality of Life and Recovery Support
Japanese hospitals place strong emphasis on side effect management, dietary therapy, and psychological counseling, leading to high patient satisfaction.

✅ 3. 頂尖癌症中心與團隊治療制度

• 例如：MD Anderson Cancer Center（德州）、Memorial Sloan Kettering（紐約）、Mayo Clinic、City of Hope
• 有跨科整合團隊（腫瘤科、胸腔外科、放射科、病理、基因諮詢）進行「腫瘤委員會討論」制定最佳方案。

✅ 4. 先進放射治療設備

• 廣泛使用 質子治療（Proton Therapy）
• 立體定位放射手術（SBRT） 治療早期肺癌的效果與手術相當

✅ 5. 臨床試驗機會多
