Aims
To compare emergency and elective presentation of gastric cancer by mode of clinical presentation, initial stage, intervention and prognosis.
Methods
Data were collected prospectively for all cases of gastric cancer presenting to a tertiary referral centre between 2003 and 2010. This was stratified by emergency and elective presentation and was analysed for mode of presentation, initial stage and outcome. Statistical analysis was performed using unpaired t-test and Chi2 test.
Results
A total of 291 patients presented: Forty-two (14.43%) were emergencies and 249 (85.57%) elective presentations. Analysis of the emergency cohort showed 25 patients presented with obstruction (59.52%), 15 presented with haematemesis (35.71%) and 2 with perforation (4.76%).
Eighteen of the emergency patients (45%) presented with stage 4 disease compared to 60 (25.42%) in the elective group (p < 0.005). Fourteen of the emergency patients were treated with curative intent (33.3%) compared with 130 (55.56%) in the elective group (p < 0.01). Over 6 years only 2 patients needed operation within 24 hours of presentation.
Overall survival at one year for emergency patients was 48.3% compared to 63.4% in elective patients (p < 0.05). There were no survivors from the emergency group after 3 years but 32.46% of the elective patients survived (p < 0.02). Elective presentation with disease stage 1A-3B had a two year survival rate of 54.95% compared to only 20% in the emergency group (p < 0.05). Of patients who underwent operative intervention 67.44% of patients who presented electively survived to 2 years. This compared to just 25% presenting as emergencies (p < 0.001).
Conclusions
Emergency presentation of gastric cancer is rare; is associated with higher stage of disease at presentation and lower rates of operability. The necessity to perform emergency operation within 24 hours is exceedingly rare. Emergency presentation is a marker of poor long term outcome for equivalent cancer stage in non-advanced (stages 1A-3B) disease.
