Abstract
INTRODUCTION: Stomach cancer is usually an adenocarcinoma arising in the stomach, and includes tumours arising at or just below the gastro-oesophageal junction (type II and III junctional tumours). The annual incidence varies among countries and by sex, with about 80/100,000 cases per year in Japanese men, 30/100,000 in Japanese women, 18/100,000 in British men, and 10/100,000 in British women. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of radical versus conservative surgical resection? What are the effects of adjuvant chemotherapy? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). RESULTS: We found 19 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. CONCLUSIONS: In this systematic review, we present information relating to the effectiveness and safety of the following interventions: adjuvant chemoradiotherapy, adjuvant chemotherapy, lymphadenectomy (radical, conservative), removal of adjacent organs, and subtotal gastrectomy for resectable distal tumours.
