Patients with low grade mucinous adenocarcinoma can have prolonged survival with debulking surgery alone. The majority of patients with truly malignant disease will die of complications from intraperitoneal progression of tumor within 2 to 5 years. The tumors are often surface oriented within the peritoneal cavity without metastases to other distant sites. The most common origin for this type of tumor is the appendix and ovary.","id":"OG001","title":"Low Grade Mucinous Adenocarcinoma"},{"description":"Adenocarcinoma of gastrointestinal origin also includes other than low grade mucinous. Aggressive gastrointestinal adenocarcinomas such as gastric, small bowel, and colon cancer , tend to be more invasive into tissues and can more readily metastasize to distant sites. The cause of death is usually directly related to intraperitoneal progression of tumor. It is a more difficult group of patients to treat with intraperitoneal therapy because of the aggressive and invasive nature of the tumors.","id":"OG002","title":"Adenocarcinoma of Gastrointestinal Origin"}],"populationDescription":"This outcome measure was not analyzed because information was not consistently available.","reportingStatus":"POSTED","timeFrame":"On study date until the first scan with imageable disease, assessed up to 100 months or more.","title":"Number of Participants With Disease-free Survival","type":"PRIMARY"}
