A Retrospective Study of Gastric Cancers in Tehran

Background: Gastric cancer is one of the most common cancers in our country. Recent studies have shown that adenocarcinoma of the cardia and distal stomach has increased in the past 25 years. However demographic data is lacking in this regard. Methods: This study is a retrospective case series study...

Summary:Background: Gastric cancer is one of the most common cancers in our country. Recent studies have shown that adenocarcinoma of the cardia and distal stomach has increased in the past 25 years. However demographic data is lacking in this regard. Methods: This study is a retrospective case series study. All records from 460 consecutive patients who were documented pathologically to have gastric cancer and had been referred for diagnosis and follow-up to a private clinic from 1992 to 2002 in Tehran were evaluated. Results: 71 records were dismissed due to incomprehensive data. Among 389 remaining records 68.5% were males; mean age was 59.4 years (range 13 to 92 years), 31.1% of patients were 40 years old or less (which is very high). Also 85% (331) of patients had adenocarcinoma and 5.9% (23) had lymphoma, 8.1% (31) had undifferentiated carcinoma while only 1% (4) of cases had gastrointestinal stromal tumor (GIST). 64% of tumors were located in the middle part of the stomach, 19% in the lower and 17% in the upper part. In our study the association between H. pylori and adenocarcinoma was 23.2% in cases younger than 40 years (P<0.001) and 56% in cases older than 40 years. Cases with lymphoma had the highest correlation with H. pylori. There was a significant difference between cancer pathology and sex (P< 0.001). Conclusion: Our data is somehow in conflict with the western data. We do not recommend blind H. pylori eradication based on positive serology (at least in Tehran) and we suggest conduction of larger multicenter studies in this field in our country.
