Progress in the cytological diagnosis of gastric lymphoma: a report of 32 cases.
Thirty-two cases of gastric lymphoma have been examined cytologically in our laboratory. In one series (1953-1972), a technique combining washings and abrasion under fluoroscopic control was used. A positive diagnosis of malignancy was made in 7 of 17 cases. In a recent series (1972-1976), 15 cases of gastric lymphoma have been studied by direct abrasion during endoscopy. Malignant cells were identified in 13 cases and a correct diagnosis of lymphoma was made in 11 cases. Biopsy was positive for malignancy in 12 cases and lymphoma was specifically diagnosed in 9 instances. Combining cytology and biopsy, a diagnosis of cancer was made in 14 of 15 cases. Endoscopic cytology appears to be far superior to blind abrasion and washings techniques in the diagnosis of lymphoma of the stomach.
