Treatment of stomach cancer: surgery, stomach removal, radio/chemotherapy
Treatment success, length and quality of life depend on early diagnosis.
In advanced cancer, a five-year survival rate of approximately 20% has been reported. When cancer is diagnosed early, the five-year survival rate increases to 95% of cases.
Depending on the results and classification of TMN, doctors will determine whether or not the tumor can be operated on.
Gastric cancer is primarily treated surgically by removing it. However, the high success rate of surgical cure of gastric cancer is only in the earlier stages of the disease.
Endoscopic resection is a surgical procedure performed when a small tumor is confined to the inner layer of the stomach lining. During the procedure, the doctor inserts a special tube through the neck into the stomach. Using the tube, he or she removes the tumor and infected tissue.
If the tumor is already too large, partial or total removal of the stomach may be done - subtotal or total gastrectomy.
In advanced stages of the disease, when the tumour is not operable because of spread to the surrounding area and metastasis, chemotherapy or radiotherapy is chosen. The aim of radiotherapy or chemotherapy is to destroy the carcinogenic cells and prolong the patient's life.
In most cases, the tumour is already at an advanced stage at the time of diagnosis. Therefore, patients often undergo preoperative chemotherapy. In most patients, surgery is followed by chemotherapy or chemotherapy combined with radiotherapy.
Surgery (removal of the tumour and infected tissue) is the method of treatment carried out to cure this stomach cancer completely.
If surgery is not possible at all, other treatment strategies are usually performed to eliminate the symptoms of the disease, prolong and improve the patient's quality of life.
Treatment of recurrent cancer depends on the extent to which the cancer has returned. Treatment options are discussed by a multidisciplinary team consisting of an oncologist, surgeon, gastroenterologist and radiologist.
