T. Nakajima et al., Gastric cancer presenting with extremely rapid growth: Unprecedented morphologic change in a short time and endoscopic estimation of its doubling time, ENDOSCOPY, 32(12), 2000, pp. 994-997
We encountered a case of gastric cancer that was initially detected as a de
ep hemorrhagic ulcer without surrounding irregular elevation, followed by r
apid protrusion in less than 1 month. Using endoscopic images in the follow
-up study, we estimated the doubling time (DT) of this unusual tumor as 9.2
days. Since the doubling time of gastric cancer is generally fairly long d
ue to exfoliation of many cancer cells into the gastric lumen, this cancer
presented with extremely rapid growth. Besides, this case reinforces that f
ollow-up study is important in terms of clinical management of ulcerative l
esions.
