Gastric cancer is a prevalent malignancy in East Asia. However, due to its highly developed early screening systems and meticulous surgical techniques, Japan consistently maintains some of the highest five-year survival rates for gastric cancer globally.
The Medical Supporter team has compiled this guide to help patients and families understand the disease and navigate the various treatment options available in Japan.
1. The "Silent" Signs of Gastric Cancer
Early-stage gastric cancer often lacks specific symptoms, frequently mimicking general gastritis or peptic ulcers. Persistent signs that warrant medical attention include:
- Upper abdominal discomfort: Dull pain, bloating, or unexplained loss of appetite.
- Gastrointestinal abnormalities: Dark, tarry stools (melena), frequent burping, or hiccups.
- Systemic reactions: Unexplained rapid weight loss and persistent fatigue caused by anemia.
2. Advantages of Advanced Treatment in Japan
Patients seeking gastric cancer treatment in Japan can access world-class technologies:
- Endoscopic Submucosal Dissection (ESD): For very early-stage gastric cancer, Japanese specialists can precisely excise the lesion under endoscopy without the need for open surgery, completely preserving stomach function.
- Da Vinci Robotic Surgery: For mid-stage gastric cancer requiring resection, robotic-assisted surgery provides superior visualization and stability. This minimizes blood loss and accelerates post-operative recovery.
- Precision Adjuvant Therapy: Based on genetic testing (such as HER2 expression), patients are matched with targeted therapies or immune checkpoint inhibitors (e.g., Opdivo), significantly improving the prognosis for those with locally advanced or metastatic disease.
3. Who Should Have Regular Endoscopy?
Prevention and early detection are critical. Annual screening is recommended for high-risk groups:
- Helicobacter pylori (H. pylori) infection: A major risk factor for gastric cancer.
- Lifestyle factors: High intake of salt and preserved foods, or a history of smoking.
- Family history: Individuals with first-degree relatives who have had gastric cancer.
4. Professional Medical Advice
When facing gastric cancer, we advocate for a proactive and precise approach to treatment. The Japanese medical environment emphasizes not only technical excellence but also a patient-centric approach to long-term management.
