Visit Specialized center of stomach cancer at Gangnam Severance Hospital

Stomach cancer treatment is a speed battle. Most people can expect full recovery if it is found in earlier stage and get treated, but if it spreads or metastasize, survical rates drop sharply from 20 to 40 percent. Gangnam Severance Hospital's stomach cancer center is actively seeking to treat earlier stage of stomach cancer as well as progressive stomach cancer in 3rd stage and 4th stages. Based on its highly experienced treatment and steady research, it will establish a treatment strategy optimized for the patient's condition to maximize its survival rate and quality of life. The basis of stomach cacner treatment is early diagnosis and treatment. According to the National Cancer Registry Statistics, The 5year survival rate exceeds 95percent of the first stage of stomach cancer, however only 5.6 percent of the 4th stage patients have remotely metastasized.

Gangnam Severance Hospital's stomach cancer center serves as the final destination for treatment of patients with stomach cancer in the 3rd stage and 4th stage. The fundamental treatment of stomach cancer is to remove all of cancer cells by surgery. However, most hospitals recommend chemotherapy rather than surgery if there are diagnosed with stage4. Roh,Sung-hoon, a professor of gastrointestinal surgery at the stomach cancer center at Gangnam Severance Hospital, said, "Even patients who gave up treatment at other hospitals will find the best treatment for their patients through multidisciplinary treatment in collaboration with various medical departments." According to the number of gastrointestinal resection procedures by stage of the 2017-2020(as of the end of October)at the stomach cancer center at Gangnam Severance Hospital, 26percent of patients in stage3 and 4 are in the same period, compared to 10~15 percent at other hospitals.

Overwhelming rate of gastrectomy in stage 3 and 4 patients compare to other hospitals

Kang(Female.45yrs)was diagnosed with stomach cancer in the 4th stage at the hospital in July and was desperate to hear that surgery would not be possible. And She didn't want to give up on hope, then visited Gangnam Severance Hospital. As a result of biopsy through endoscopy and computed tomography(CT)test, cancer cell invaded almost all part of stomach and the stomach wall was thickened in overall. When it was confirmed via laparoscope, even peritoneal metastasis was found. Kang recevied 8session of chemotherapy at the recommendation of her medical staff and confiremed that the size of cancer had decreased in November. on the 1st, she went into an operating room for conversion surgery. Fortunately, the peritoneal metastasis has also improved to the extent that only traces of the perioneal metastasis remain and she is under recovery.

In general, if it is diagnosed as stage 4 of stomach cancer, do not proceed surgery and just go on chemotherapy to prevent aggravation of disease. In this case it is impossible to have full recovery and also most of them can only live for 1year. However, Stomach cancer center at Gangnam Severance Hospital is aiming to improve survival rate with conversion surgery. It is an operation to resect stomach and metastasis if metastatic lesions are removed or reduced after treating patients diagnosed with stage 4 of stomach cancer due to metastasis in peritoneal, liver and aortic lymph nodes. According to a study by Severance Hospital, the survival period was 9 to 11 months when only chemotherapy was performed on stage 4 of stomach cancer patients, while the conversiton surgery was extended to 26 months. "Professor Roh emphasized that conversion surgery can be expected to extend the long term of survival rate, and its attributes to impact the quality of life,"

Recently, some patients with stage 3 of stomach cancer are also attempting prior to chemotherapy to reduce the recurrence rate. The standard treatment for stage 3 of stomach cancer is to perform adjuvant chemotherapy after surgery. However, the results of multicenter clinical trials showed that when preoperative chemotherapy was administered to patients with stomach cancer at the end of stage 3 or with deep cancer invasion and lymphatic gland metastasis, the disease-free period was longer than that of postoperative chemotherapy which was found clearly.


Development of a model to predict lymphatic metastasis of stomach cancer

About 70% of domestic stomach cancer patients are early stage of stomach cancer. If there is no lymphatic gland metastasis, only the mucous membrane of the stomach, and the size is less than 3cm, the patient is looking for a complete recovery with a gastoscopy (ESD)without surgery. It is a surgery that slightly cuts out cancer. Yoon,Young-hoon, head of the stomach cancer center at Gangnam Severance Hospital, said, "We do a lot of endoscopic gastrointestinal detachment such as cases of request from other hospitals or re-surgical cases," in addition, " The medical team's experience and technology are supported to produce excellent clinical results."

Recently, artificial intelligence (AI) and deep learning technology have been applied to develop a model that predicts the probability of lymph gland metastasis according to the size, differentiation, and shape of stomach cancer. Because of its excellent predictability, research is being conducted so that it can be used to determine the optimal treatment policy. Director Yoon emphasized that , “Early gastric cancer is treated with minimal invasiveness and maximal preservation of gastric function in consideration of the quality of life after treatment, beyond cure.” I will do my best.”
