Gastrointestinal metastases from extra-abdominal tumors.
Over a period of 4 years, metastatic lesions to the gastrointestinal tract were analysed in postmortem and clinical series. Melanoma, breast and lung cancers were the most common primary lesions. The topography of parietal involvement shows that all patients evidenced tumor involvement of the submucosa, but not all of them revealed invasion of the mucosa and serosa, suggesting a hematogenous route of dissemination. Although almost all cases had widespread disease at the time of referral for diagnosis, patients who were submitted to surgery had a median survival of 8 months (range 1-48). In selected cases, surgery offers good palliation and may permit resumption of otherwise active chemotherapeutic treatments.
