State of the scientific evidence and recommendations for the management of older patients with gastric cancer.

Gastric cancer is one of the most frequent and deadly tumours worldwide. However, the evidence that currently exists for the treatment of older adults is limited and is derived mainly from clinical trials in which older patients are poorly represented. In this article, a group of experts selected from the Oncogeriatrics Section of the Spanish Society of Medical Oncology (SEOM), the Spanish Group for the Treatment of Digestive Tumours (TTD), and the Spanish Multidisciplinary Group on Digestive Cancer (GEMCAD) reviews the existing scientific evidence for older patients (≥65 years old) with gastric cancer and establishes a series of recommendations that allow optimization of management during all phases of the disease. Geriatric assessment (GA) and a multidisciplinary approach should be fundamental parts of the process. In early stages, endoscopic submucosal resection or laparoscopic gastrectomy is recommended depending on the stage. In locally advanced stage, the tolerability of triplet regimens has been established; however, as in the metastatic stage, platinum- and fluoropyrimidine-based regimens with the possibility of lower dose intensity are recommended resulting in similar efficacy. Likewise, the administration of trastuzumab, ramucirumab and immunotherapy for unresectable metastatic or locally advanced disease is safe. Supportive treatment acquires special importance in a population with different life expectancies than at a younger age. It is essential to consider the general state of the patient and the psychosocial dimension.
