Management of gastric adenocarcinoma

Gastric adenocarcinoma is the second most common cause of cancer death worldwide. The prognosis for patients with gastric adenocarcinoma depends on the stage of the disease at the time of diagnosis and treatment. Early gastric cancer, limited to the mucosa and submucosa, is best treated surgically and has a five-year survival rate of 70-95%. Surgical resection remains the primary curative treatment for localised disease. Despite this, the overall survival remains poor. The management of localised gastric adenocarcinoma is complex, and at present there is proven benefit of both preoperative chemotherapy and postoperative chemoradiotherapy. There is no standard regimen of chemotherapy for metastatic disease, although the regimen of ECF (epirubicin, cisplatin and fluorouracil) is the most used regimen, with a median survival of 7-9 months. With new regimens of chemotherapy, such as DCF (docetaxel, cisplatin and fluorouracil) or the combination of irinotecan, cisplatin and bevacizumab, the median survival has increased. Other new agents are under investigation.
