Stages of stomach cancer
Stomach cancer is staged from 0 (carcinoma in situ), then I to IV, the former representing a more isolated cancer while the latter refers to different stages of cancers, with stage IV being used to classify distant metastasis.
Stomach cancer is clinically staged according to the American Joint Committee on Cancer (AJCC) TNM system. This gauges the Tumor size, lymph Node involvement and Metastasis of the cancer.
Pathologic staging is done during surgery, while clinical staging is done prior to surgery or when surgery is not viable, and is based on the physical exam, biopsy, and diagnostic imaging.
Prognosis: Stomach Cancer Stage 3 Survival Rate
When it comes to stomach cancer survival, the prognosis is determined by a 5-year survival rate which is a percentage of people in a treatment group who are alive five years after they were diagnosed and/or treated for their disease.
Patients with stage IA stomach cancer have a 5 year survival rate of 94%, while those with stage IB have a 88% survival rate. The stomach cancer stage 3 survival rate is 18%, although other studies say that it may go up to 25%.
Unfortunately, in most studies conducted, patients with stage IV stomach cancers have no 5 year survival statistics as most patients don’t live to reach 5 years after diagnosis.
