title: Has the incidence of primary gastric lymphoma increased?
abstract: 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.
