Purpose of review: Despite a decline in the incidence of upper gastrointestinal adenocarcinomas in North America and western Europe during the past century, treatment remains a challenging problem for oncologists. The poor outcome associated with surgical resection with curative intent has generated intensive investigation of combined modality treatment approaches including systemic chemotherapy to prevent recurrences and improve overall mortality. This article reviews data on neoadjuvant and perioperative treatment modalities for upper gastrointestinal adenocarcinomas.
Recent findings: Postoperative chemoradiation is favored in the USA for good performance status patients with resected, high-risk gastric or gastroesophageal junction carcinoma (more stage IA). More recently, the UK Medical Research Council Adjuvant Gastric Infusional Chemotherapy (MAGIC) and Fédération Nationale des Centres de Lutte Contre le Cancer-Fédération Francophone de Cancérologie Digestive trials results, showing survival benefit with perioperative chemotherapy in operable gastric and lower esophageal cancers, have had an impact on the treatment practice in Europe.
Summary: Novel strategies, involving induction with chemotherapy followed by preoperative chemoradiation, addition of targeted therapies to perioperative chemotherapy or use of new cytotoxic regimens are under evaluation to improve current standards and try to tailor therapeutic strategies.
