The morphology of superficial and nonprotruding neoplastic lesions is relevant to the prognosis. Following endoscopic detection, the lesions are analyzed using chromoendoscopy and assigned a subtype of the type 0 classification. The choice between endoscopic or surgical treatment is based on this description.

The polyp-carcinoma hypothesis prompts colonoscopists to search only for polypoid lesions when screening for malignancy. A significant proportion of early colorectal neoplasms may therefore be missed. European colonoscopists require training in the recognition of flat elevated and depressed lesions in order to detect colorectal malignancies in their early stages.

One hundred and ninety five consecutive, potentially curative resections for adenocarcinoma of the stomach were performed in one surgical department between 1970 and 1989: 76 patients underwent gastrectomy with splenectomy and 119 gastrectomy without splenectomy. Operative mortality was 12% after gastrectomy with splenectomy, but only 2/5% after gastrectomy without splenectomy (p<0.05). Postoperative complications were also significantly more common when splenectomy was combined with gastrectomy (41% v 14%, p

Patients diagnosed with LGD during surveillance of Barrett's esophagus are at a considerably increased risk of progressing to develop esophageal cancer over an 8-year period but most deaths are not cancer-related.
