Expresión de CD44 (HCAM) en el carcinoma subseroso de la vesícula biliar

Background: HCAM or CD44 is a multifunctional cell adhesion molecule, related to cell-cell, cell-extracellular matrix interactions and involved in tumor invasion. Aim: To study the importance of CD44 expression in subserous gallbladder carcinoma. Material and methods: One hundred five samples (93 fe...

Aim: To study the importance of CD44 expression in subserous gallbladder carcinoma. Material and methods: One hundred five samples (93 female) of subserous gallbladder carcinoma and 33 non tumoral gallbladder were studied. CD44 was stained using the streptavidine-biotin technique, using human anti CD44 antibodies. Eighty subjects with carcinoma were followed for a period up to 105 months. Results: Mean age of patients was 62,6 years old, all tumors were adenocarcinoma, all were silent and 13% were well differentiated. CD44 was expressed in all controls and in 91%, the expression was normal. In 57% of cancer samples, CD44 expression was abnormal, in 50% it was less expressed and in 24%, it was not expressed. No differences in CD44 expression was observed between mucosa from control samples and mucosa adjacent to the tumor or superficial or deep tumoral areas. Global five years survival was 40%. No significant differences in survival were observed in those tumors with a lower of absent CD44 expression. Six patients with a higher expression died before 18 months of follow up. Conclusions: Nearly 50% of subserous gallbladder carcinomas show an abnormal CD44 expression (Rev Méd Chile 2001; 129: 727-34).info:eu-repo/semantics/openAccessSociedad Médica de SantiagoRevista médica de Chile v.129 n.7 20012001-07-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0034-98872001000700004es10.4067/S0034-98872001000700004
