“Stomach cancer” is the third most common cancer in Japan. It arises in the cells in the innermost mucosa of the stomach, and goes deeper invading the submucosal layer, the proper muscular layer, the subserosal layer and the serosa. In recent years, diagnostic technology has shown significant advancement, which results in a fact that more than half of the cases are detected as "early-staged cancer," which stays within the mucosa or the submucosal layer. Treatment technology has also advanced lately, which has contributed to the complete cure of more than 90% of the early-staged gastric cancers. Treatment method is based on the “Japanese Gastric Cancer Treatment Guidelines” developed by the Japanese Gastric Cancer Association and is chosen among endoscopic treatment, surgery and chemotherapy (anti-cancer drug therapy) depending on the disease progression.
Generally speaking, gastric cancer can be completely resected by endoscopy when it is detected at a fairly early stage, while surgery is the most effective treatment for complete cure for early-staged stomach cancers when they can’t be removed by endoscopy, as well as for advanced cancers. The endoscopic resection is performed at the Division of Endoscopy, and the surgeries are performed at the Division of Gastric Surgery.
Surgeries for all the tumors in the stomach and the surrounding regions, such as SMT (submucosal tumor) including GIST (gastrointestinal stromal tumor), are performed at this division
We perform surgeries standardized in the “Japanese Gastric Cancer Treatment Guidelines” according to the disease progression. The number of gastric cancer surgeries performed here is the 4th-largest (as of 2023) in Japan. It proves the fact that ample experiences can guarantee an optimal choice of cancer treatment, as well as a safe and reliable surgery resulting in a positive outcome from the treatment.
Gastric cancer surgeries are not limited to a conventional “open abdominal surgery” alone, which is to cut open the abdomen. The variation includes “laparoscopic surgery” as well as “robotic surgery” with a tiny camera and surgical instruments being inserted through very small incisions into the abdomen. Currently we are quite focused on performing minimally invasive surgeries (i.e., laparoscopic surgeries and robotic surgeries).
We have 7 surgeons with certified expertise in this division, who perform laparoscopic surgeries with the utmost caution for safety. Also, robotic surgery is being adopted proactively here. We have already performed 741 robotic surgeries as of the end of 2024, which is one of the biggest numbers in Japan, since we started adopting the procedure in 2012. As the Shizuoka Cancer Center meet the standards as an eligible medical institution, the patients here can receive the robotic surgery as a cancer treatment covered by Japanese public health insurance.
For a surgery for a submucosal tumor in the stomach, open abdominal surgery will be adopted when the tumor mass is 8 cm or bigger in diameter, and when it is smaller than 8 cm, laparoscopic or laparoscopy-and-endoscopy cooperative surgery will be adopted for segmental resection.
“Clinical trials,” which are to evaluate the effects of new treatments, play crucial roles in defining future directions of gastric cancer treatment in Japan. The Division of Gastric Surgery at the SCC is one of the leading members of the JCOG (Japan Clinical Oncology Group) and is actively participating in clinical trials when they seem useful enough. At the same time, the Division designs versatile trial plans in the field of stomach resection and stomach cancer, and is implementing them.
At the SCC, surgeries for gastric cancers are performed at the Division of Gastric Surgery, but we work together in tight cooperation with the Division of Endoscopy where endoscopic treatments are focused on, as well as the Division of Gastrointestinal Oncology where chemotherapy (anti-cancer drug treatments) is handled. At each division, all the cases are thoroughly discussed to provide each patient with an optimal cancer treatment, striving to offer highly qualified medicine.
