ND4 monoclonal antibody recognizes a tumor marker found on poorly differentiated colorectal cancer. We demonstrate its expression in 25% of gastrointestinal neuroendocrine tumors, which also express CEA in 37% of cases. As in colorectal cancer the ND4 marker is predominantly membrane bound in a colonic neuroendocrine tumor cell line, LCC-18 (p < 0.05). The ND4 marker is absent in a poorly differentiated colorectal cancer cell line that does not express CEA or other tumor antigens. Shed antigen in the serum of patients with neuroendocrine tumors is detected in only five of seven patients with the carcinoid syndrome and two of four of those without evidence of the syndrome. However, the reactivity was less in the patients with localized disease, and this test is unlikely to be of diagnostic utility in this group of patients. The sharing of this antigen in colorectal cancer and neuroendocrine tumors is not universal, but does support the common-cell progenitor theory for the origin of these tumors.

Significant progress is being made in the prevention of hepatitis B-related hepatocellular carcinoma (HCC) but hepatitis C-related HCC is increasing in the West and therapeutic advances in established disease have been modest. Although ablative therapies, including surgical resection, seem effective in patients with small tumours these only represent a minority of patients. For the majority with advanced disease there is some evidence for survival benefit for transarterial chemoembolisation but only in very carefully selected patients. Systemic chemotherapy is of unproven benefit and is now largely confined to clinical trials. In contrast, there has been a steady improvement in the outlook of patients with established metastatic liver cancer when the primary site is colorectal. Survival has increased from around six months to almost two years with the introduction of new cytotoxic agents, irinotecan and oxaliplatin. Somatostatin analogues have had a dramatic impact on the symptomatic control of neuroendocrine tumours, metastatic to the liver that result in the carcinoid syndrome.
