Gastric Cancer Overview

Gastric cancer is the fifth most common malignancy and third leading cause of cancer mortality globally, arising predominantly as adenocarcinoma from the gastric mucosa, with Helicobacter pylori infection, dietary carcinogens, tobacco, obesity, and hereditary syndromes including CDH1 germline mutations constituting principal aetiological drivers. Molecular classification encompasses EBV-positive, microsatellite instability-high, chromosomally unstable, and genomically stable subtypes, each carrying distinct therapeutic implications. HER2 amplification occurs in approximately 15-20% of gastric and gastroesophageal junction adenocarcinomas, representing a critical actionable biomarker. Patients present with epigastric pain, dysphagia, early satiety, weight loss, and anaemia, with many diagnosed at advanced stages given insidious onset. Upper endoscopy with biopsy establishes histological diagnosis, while CT staging, PET imaging, and laparoscopic staging address metastatic and peritoneal disease assessment. Comprehensive molecular profiling encompassing HER2, MSI, PD-L1 CPS, and FGFR2 status is mandatory at diagnosis. Perioperative FLOT chemotherapy is the established standard for resectable disease. Advanced HER2-positive gastric cancer is addressed with trastuzumab combined with chemotherapy, with trastuzumab deruxtecan demonstrating transformative second-line efficacy in the DESTINY-Gastric trials. Nivolumab combined with chemotherapy is the established frontline standard for HER2-negative advanced disease with CPS of 5 or above. Zolbetuximab, targeting CLDN18.2, combined with chemotherapy represents a significant newly approved frontline advance for CLDN18.2-positive tumours. MSI-H disease benefits from pembrolizumab immunotherapy. Prognosis remains poor in advanced disease; multidisciplinary tumour board evaluation, nutritional support, and early palliative integration are indispensable to patient-centred care.
