The Lauren classification highlights the role of epithelial-to-mesenchymal transition in gastric carcinogenesis: an immunohistochemistry study of the STAT3 and adhesion molecules expression.

Background And Aims: Despite some recent advances, gastric cancer remains an important cause of death at world level. This indicates an absence of therapeutic options, stemming from the limited understanding of the molecular mechanisms involved in carcinogenesis. Nearly fifty years ago Lauren classified gastric cancers, according to the morphological aspect, as intestinal or diffuse.

[Adenocarcinoma of minor salivary gland origin: a recently described lesion. A case report].

Cribriform adenocarcinoma of salivary gland origin is a rare and recently described lesion. In spite of the high incidence of metastatic spread, the prognosis remains very good. We report a case of a 64-year-old man with cribriform adenocarcinoma of salivary gland origin of the ventral tongue without locoregional or distant metastasis.

Pre- and posttherapeutic staging of laryngeal carcinoma involving anterior commissure: review of 127 cases.

Background. The objective of this study is to assess the accuracy of pre- and posttherapeutic staging of endolaryngeal cancer involving anterior commissure. Materials and Methods.

[High-grade small bowel angiosarcoma associated with angiosarcomatosis: a case report].

Angiosarcoma is a rare soft-tissue neoplasm occurring most often in the skin and the subcutaneous tissues and very rarely in the gastrointestinal tract. We report a case of a 25-year-old woman who presented with a small intestinal angiosarcoma associated with angiosarcomatosis. The diagnosis was established on surgical intestinal resection, that showed a high-grade angiosarcoma with epithelioid component and foci of agressive form of hemangioendothelioma.

[Lung metastases of epithelioid sarcoma revealed by bilateral spontaneous pneumothorax: a pathological diagnosis].

Spontaneous pneumothorax may be one of the presenting manifestation of metastatic epithelioid sarcoma even if imaging does not show evident metastatic nodules. We report the case of a 24-year-old man presenting a bilateral spontaneous pneumothorax in association with an epithelioid sarcoma developed in the right foot. CT-scan revealed bilateral microcystic lesions with no evidence of metastatic disease.

The effectiveness of trastuzumab (Herceptin) combined with chemotherapy for gastric carcinoma with overexpression of the c-erbB-2 protein.

The c-erbB-2 protein is overexpressed in 7% of gastric cancer cases, suggesting that anti-c-erbB-2 antibody therapy (trastuzumab; Herceptin) could be used. We report here a 28-year-old woman with metastatic gastric cancer overexpressing c-erbB-2 (3 + strong membrane staining on immunohistochemistry) who was treated with trastuzumab in combination with chemotherapy. A complete response was obtained with a combination of trastuzumab and oxaliplatin and was maintained with trastuzumab alone for 18 months.
