Primary Gastric Lymphoma in Auckland, New Zealand

Abstract

The case‐notes of 30 patients presenting with primary gastric lymphoma in the auckland area during 1969–87 have been reviewed. The mean age of the study group was 62 years, and 16 were female and 14 were male. There were 22 european, one maori and seven polynesian patients. The most common presenting symptom was abdominal pain and five patients presented acutely with gastrointestinal haemorrhage. The lesions occurred more frequently in the distal stomach and half were polypoid and half were ulcerating. They tended to be of substantial size at presentation, with seven being greater than 10cm in diameter. Nine lesions were confined to the stomach, 12 involved the surrounding lymph nodes and eight were invading adjacent organs. Twenty‐three patients underwent partial or total gastrectomy. Four of these received postoperative radiotherapy, and adjuvant chemotherapy was administered to 13. Chemotherapy, or combination chemo‐and radiotherapy were used as the primary treatment in seven patients. Following surgical treatment, 18 patients remained alive and well. Five of the seven patients treated non‐surgically were dead of disease at the time of study and the other two remained alive with persisting disease. The following factors were found to affect prognosis adversely: weight loss of greater than 5 kg, tumour invasion of adjacent organs, and non‐surgical primary treatment. Involvement of the lymph nodes draining the stomach did not appear to worsen the outlook, and there was little correlation between lesion size and prognosis.
