Abstract
Although decreasing in the incidence over the last years, currently gastric adenocarcinoma represents the second cause of cancer related-death worldwide. Further knowledge and novel therapies are desperately needed in order to make the prognosis of these patients more acceptable. Infact, even though in recent years numerous staging parameters have been largely studied and unanimously recognized for their clinical and prognostic value, today too many shadows still exist around the capacity to predict exactly the natural history or post-treatment behavior of this cancer even among patients of the same stage. This study has identified the presence of isolated cancer cells as well as tumor markers (CEA, Ca 19.9, Ca 72.4 and Ca 50) from the gastric lavage of patients affected by gastric adenocarcinoma. Such findings led to the hypothesis that endoluminal exfoliation of neoplastic cells and the release of their products (tumor markers) into the gastric juice might be an expression of neoplastic behavior as well as aggressive malignancy. Should this hypothesis become a reality, some important progress could be made in the knowledge, staging, prediction as well as management and follow-up of this inauspicious type of cancer.
