CEA levels in gastric juice in precancerous conditions and cancer.

First described in 1965 as a specific antigen for cancer of the colon, CEA is now considered to be an antigen associated with many types of malignant neoplasia, although the CEA-Test's role in clinical routine has yet to be clearly defined. In the present study CEA levels in gastric juice were measured in subjects with gastric carcinoma (n = 25) and with benign gastric lesions (n = 171). CEA was significantly (p less than 0.05) higher in patients with gastric carcinoma (GC) than in subjects with benign gastric lesions, other than chronic atrophic gastritis (CAG) associated with intestinal metaplasia (IM). In this latter condition CEA levels were similar to those in patients with GC. These results suggest that the assay of CEA in gastric juice could be included in the diagnostic program for gastric cancer and its precursors with the aim of assessing its utility as risk indicator in the management of precancerous conditions and lesion.

Early gastric cancer in the province of Forlì: follow-up of 337 patients in a high risk region for gastric cancer.

Long-term clinical outcome was analysed in a series of 337 patients with early gastric cancer (EGC) at a median follow-up of 8 years. Tumours were classified according to the macroscopic and microscopic criteria proposed by the Japanese society of gastroenterological endoscopy (JSGE) and Lauren, respectively. Type of penetration (PEN) was classified according to Kodama. Overall survival rate was 92% at 5 years and 88% at 8 years and was significantly related to depth, type of penetration, lymph node status and tumour size. A significantly lower 5-year survival (p<0.05) was observed for patients with lymph node metastases and PEN A type EGC (55%) or for those with node-positive tumours and submucosal wall penetration (58%) than for the other pathologic subgroups. Therefore, these two subgroups should be considered as advanced gastric cancer patients from the prognostic point of view. Moreover, multivariate analysis by Cox regression model showed the degree of lymph node involvement and Kodama's type PEN A as the only independent prognostic factors.

Identification of occult micrometastases in patients with early gastric cancer using anti-cytokeratin monoclonal antibodies.

The presence of occult micrometastases was evaluated in 1488 lymph nodes removed from 139 patients with node-negative early gastric cancer (EGC). Additional multiple levels of the lymph nodes were examined with haematoxylin-eosin staining and keratin immunostaining. Occult nodal micrometastases were detected in 24 patients (17%) in one or more lymph nodes dissected after a gastrectomy. The cases investigated were a small group from a total of 412 EGC patients who underwent surgical treatment in our hospital between 1976 and 1997; the mean follow-up period was 9 years (range 1-22). We found no significant differences between cytokeratin-negative and positive patients regarding the following clinicopathological parameters: age, gender, tumour size and site, macroscopic and microscopic type, depth of invasion and type of infiltration, according to Kodama's classification. The survival rate at 5 years was 88% and 87% for cytokeratin-negative and positive patients, respectively (log-rank = 0.6; ns). Our data suggest that occult micrometastases do not add useful information and immunohistochemical studies to detect them are probably unnecessary.

[Value of the in situ hybridization technique in the diagnosis of human papilloma virus infections of the uterine cervix. Correlations between the human papilloma virus type and the morphological features].

Clinico-pathologic, epidemiologic and molecular analytic studies have shown that: i) the squamous cancer of the uterine cervix derives from intraepithelial lesions with different degrees of atypia; ii) human papillomavirus (HPV) can play a fundamental role in the progression of these lesions. We have examined 219 uterine cervix biopsies by means of the in situ hybridization technique (ISH) using biotinylated probes for 6/11, 16/18 and 31/35/51 HPV strains. The histologic lesions were as follows: 104 (49.7%) focal koilocytotic lesions 26 (11.8%) low grade intraepithelial lesions (SIL) 45 (20.5%) high grade intraepithelial lesions (SIL) 18 (8.2%) condylomata acuminata 21 (9.8%) invasive cancers. The percentage of the positivity found in the whole material examined is 14.1%. In particular, none of the 109 cases of focal koilocytotic lesions was positive, whereas the 28.1% of the remaining 110 biopsies turned out to contain HPV. We hypothesize that our small percentage of positivity in preinvasive and invasive lesions of the uterine cervix can be due to the fact that the HPV is not the only cancerogenic factor involved, although the possibility of a low sensitivity of the technique cannot completely be excluded.

[Peripheral T-cell lymphoma associated with hemophagocytic syndrome: a recently identified entity. Clinico-pathologic and immunohistochemical study of 2 cases].

The authors report on two examples of peripheral T-cell lymphoma associated with hemophagocytic syndrome. The latter represents a recently described entity, which is characterized by pancytopenia, hepatosplenomegaly, fever and rapid downhill clinical course. Microscopic examination of different tissue samples shows bone-marrow, liver and spleen infiltration by small-medium sized lymphoid elements, which display peripheral T-cell phenotype and are associated with an exuberant hyperplasia of hemophagocytosing, benign-looking histiocytes. The clinical and pathological findings, along with the main differential diagnoses, are discussed.

[Epidermoid cyst of the spleen. Presentation of a case].

Cystic lesions of the spleen are unusual. They are classified essentially as: parasitic or nonparasitic, based on their etiology, and true or pseudo based on the presence or absence of lining epithelium. The pathogenesis of true cysts is unknown and numerous hypotheses are given by different Authors. After a short review of the literature, the Authors describe the clinical and pathological data of a case of epithelial (epidermoid) splenic cyst occurs in a 12-year-old woman. The Authors put forward some personal observations on pathogenesis, still doubtful, by means of histochemical and immunohistochemical study.
