Fig. 8.11 Hepatocellular carcinoma in a 17-year old patient with Fanconi anaemia. A Green bile staining and extensive necrosis and haemorrhage. B Trabecular and pseudoglandular pattern with bile plugs. Invasion into the blood vessels, in particular into the portal vein, is a characteristic of HCC. Tumour thrombi in the portal veins are present in more than 70 of autopsies of advanced HCCs. Intra-hepatic metastases is caused mostly by tumour spread through the portal vein branches. Tumour...

Of the colon and rectumRHrSnobdn

Endocrine tumours of the large intestine are defined as in the small intestine. Endocrine tumours of the colon have an incidence of 0.07-0.11 up to 0.21 cases per 100,000 population per year 1251 . In a recent series, carcinoids from caecum to transverse colon (midgut) represented about 8 and descending colon and rectosigmoid (hindgut) carcinoids about 20 of 5973 gastrointestinal carci-noids 1251 . Rectal carcinoids had a reported incidence of 0.14-0.76 cases per 100,000 population per year. In...

M1

This classification applies only to primary hepatocellular and cholangio-(intrahepatic bile duct) carcinomas of the liver. 2 A help desk for specific questions about the TNM classification is available at http tnm.uicc.org. 3 For classification, the plane projecting between the bed of the gallbladder and the inferior vena cava divides the liver in two lobes.

C

The non-neoplastic mucosa distant from an anaplastic large cell intestinal T-cell lymphoma displays villous atrophy, crypt hyperplasia (A) and an increase in cytologically unremarkable intraepithelial lymphocytes (B) without evidence of lymphoma. Both the lymphoma (ALCL) and the intraepithelial lymphocytes (IEL) share the same dominant T-cell clone (C) and the same aberrant immunological phenotype. band-like or patchy microscopic lesions entirely confined to the...

Prognosis and predictive factors

Ductal adenocarcinoma is fatal in most cases 639 . The mean survival time of the untreated patient is 3 months, while the mean survival after radical resection varies from 10-20 months 560, 692, 814, 1955 . The overall 5-year survival rate of patients treated by resection is 3-4 639 , although in selected and stage-stratified series survival figures approaching 25 or even 46 have been reported 560, 1955, 1966, 1976 . Unresectable carcinomas are treated with palliative bypass operations....

Adenocarcinoma of the oesophago SJ Spechlerp Hainaut

Adenocarcinomas that straddle the junction of the oesophagus and stomach are called tumours of the oesophagogastric (OG) junction. This definition includes many tumours formerly called cancers of the gastric cardia. Squamous cell carcinomas that occur at the OG junction are considered carcinomas of the distal oesophagus, even if they cross the OG junction. Definition of the oesophagogastric junction The OG junction is the anatomical region where the tubular oesophagus joins the stomach. The...
