- Review the most characteristic imaging features of gastric cancer. -Focus on the differential diagnosis of the most frequent histological subtypes of gastric carcinoma,
which are: adenocarcinoma , lymphoma ,
gastrointestinal stromal tumor ( GIST ) and carcinoid tumor.
INTRODUCTION Gastric cancer is the 6th most frequent malignancy in Europe and constitutes the 2nd most common carcinoma involving the gastrointestinal ( GI ) tract ,
after colorectal carcinoma.
It is considered the 4th most common cause of cancer-related death. Delayed detection is usual,
with the disease being disseminated in more than a half of the patients.
approximately 60% of allpresent with unresectable disease.
As a consequence,

Findings and procedure details
Once reviewed the key concepts of gastric cancer,
the next step is to approach its imaging features.
Gastric cancer consists offour main histopathologic subtypes,
each of them presenting different biological behaviouranddistinct imaging appearance on which radiologists can relyon to reach an accurate diagnosis. a.
GASTRIC ADENOCARCINOMA It is the dominant subtype of gastric cancer (accounting for almost 90-95% of all cases). General concepts - Gastric ADC presents high incidence in Asia ,...
Imaging diagnosis of gastric cancer is challenging due to its wide spectrum of radiological findings. However,
recognizing the most determinant characteristics of its main subtypes makes this task easier and enables an accurate and prompt diagnosis of the disease,
leading to better survival rates.
