Patterns of care and outcomes for gastric and gastro‐oesophageal junction cancer in an Australian population

BACKGROUND A single state-wide upper gastrointestinal (GI) cancer video-linked multidisciplinary team (MDT) meeting guides management and evidence-based care for all newly diagnosed upper GI cancer patients in South Australia. This study determined the patterns of care and outcomes for patients diagnosed with gastric and gastro-oesophageal junction (GOJ) cancers. METHODS Patients diagnosed with gastric cancer and GOJ (Siewert III) cancer between June 2012 and June 2016 were included. Patient demographics, cancer stage, histology, diagnostic modalities and treatment data was analysed from a prospective database. Stage-specific survival outcomes were determined and analysed for each treatment modality. RESULTS The study included 218 patients and at diagnosis 132 (61%) patients had stage I-III and 86 (39%) patients had stage IV disease. One hundred and ninety-five (89%) patients had gastric cancer and 23 (11%) had GOJ cancer (Siewert III). One hundred and nine (50%) patients underwent surgery, with 92% R0 resection rate. Forty-six patients received perioperative chemotherapy and 111 (51%) patients received palliative intent treatment. Median overall survival for stage II, III and IV cancers was 57.6 (95% CI 57.6-NR), 22.8 (95% CI 20.4-43.2), and 6.0 months (95% CI 4.8-8.4) respectively (p
