[Immunoscintigraphy in stomach neoplasms with anti-CEA BW 431/26 monoclonal antibodies marked with Tc 99 m]. / Inmunocintigráfia en cáncer gástrico con anticuerpo monoclonal anti-CEA BW 431/26 marcado con TC 99 M.

A 57 year old female had a tubular gastric adenocarcinoma confirmed by endoscopy and radiologic studies. Echotomography of the abdomen revealed multiple adenopathies. Immunoscintigraphy with 99mTc labeled anti-CEA BW 431/26 monoclonal antibody was performed. Images obtained at 6 and 24 h showed a significant uptake at the primary lesion and at periaortic adenopathies both in conventional gamma-camera and single emission photon tomography. This immuno-scintigraphic technique may be helpful in the management of patients with gastric cancer.

[Selective chemoembolization with adriamycin-Urografin-Lipiodol in the treatment of hepatocarcinoma]. / Quimioembolización selectiva con adriamicina-Urografin-Lipiodol, en el tratamiento del hepatocarcinoma.

Various methods of regional chemotherapy have been used in patients with non resectable heptic carcinoma. We report our preliminary experience with embolization using adriamycin-urographin-lipiodol in 2 patients with this cancer in whom a considerable reduction of tumoral mass was observed. The pertinent literature is briefly commented.
