There is evidence that 15 % of gastric cancer patients in Zambia survive more than one-year after diagnosis. The major contributing factor to these poor outcomes is late case detection. We set out to investigate the time course of gastric cancer diagnosis in Zambia. The study was conducted at the University Teaching Hospital, in Lusaka. Consenting patients presenting to the endoscopy unit were enrolled and their endoscopic findings recorded. An interviewer-administered questionnaire was used to collect information on basic characteristics, presenting symptoms and duration. We enrolled 388 patients, 92 (24%) of whom had gastric cancer. About two-thirds of the gastric cancers were located in the distal part of the stomach. The median time to endoscopic gastric cancer diagnosis was 12 weeks, IQR 4-32 weeks after the first health care consultation. This was despite gastric cancer patients seeking healthcare attention within a median of 2 weeks, IQR 0-4 weeks of noticing the symptoms. Patients presenting with persistent vomiting or evidence of blood loss had significantly shorter delays than those with abdominal pain (p<0.05 and p<0.001 respectively). Delayed referral for diagnostic endoscopy is a contributing factor to late gastric cancer diagnosis in Zambia. The delay is highest in patients presenting with abdominal pain.
