Ghrelin and gastrin in advanced gastric cancer before and after gastrectomy

Table 3 Plasma gastrin concentrations (median and range) in gastric cancer patients before surgery, 4-5 yr after surgery, and in healthy controls, under fasting and postprandial (60 and 90 min after a meal) conditions (95% CI) (pmol/L)

	Median fasting plasma gastrin level	Median plasma gastrin level 60 min postprandial	Median plasma gastrin level 90 min postprandial
Patients with GC (before surgery)	29 (20–43)	38 (24.5–54.2)	37 (26.4–53)
4–5 yr after gastrectomy	25.4 (14–45.5)	25.1 (14.5–43.2)	23 (13.5–39)
Controls	18.312 (8.4–39.5)	39 (19.1–79)	40 (20–79)

¹Indicates significant difference between control and postprandial value recorded at 60 min after a meal (P = 0.0027);

²Indicates significant difference between control and postprandial value recorded at 90 min after a meal (P = 0.0036). GC: Gastric cancer.
