Various reports from the surgical and gastroenterologic literature have stated that the incidence of primary gastric lymphoma has increased. Other reports have claimed that this is a relative increase or represents referral center bias. The current study was designed to determine if the incidence of primary gastric lymphoma has increased in the community hospital setting. A total of 147 cases of gastric neoplasms were reviewed over a 10‐year study period. The cases were divided into two 5‐year periods, i.e. , 1978‐82 and 1983‐87. There were two new cases (2.8%) of primary gastric lymphoma in the period 1978‐82 and 11 new cases (19%) in the period 1983‐87. The difference in proportion of primary gastric lymphoma between these two time periods was statistically significant ( P = 0.01 by chi‐square analysis). This increased incidence of primary gastric lymphoma is difficult to explain, but it must be recognized by surgeons and endoscopists.
