Primary gastric lymphoma in Jordan with special emphasis on descriptive epidemiology.
The aim of this study was to examine the clinicopathological features and epidemiology of primary gastric lymphoma in Jordan as a model for Middle East countries where such data is scarce. From 1991--2002, 219 patients with primary gastric malignancy were managed at our hospitals. Among these there were 19 patients with primary gastric lymphoma. Pertinent data for these patients were analyzed. Primary gastric lymphoma constituted 65.5% of all gastrointestinal lymphoma and 8.7% of all gastric malignancies. Male-to-female ratio was 2.8:1. The mean age was 56 years (range 39--82). The incidence was 0.6/100,000. The proximal third was the most common localisation. Abdominal pain was the commonest presentation. Low-grade MALT lymphomas, high-grade MALT lymphomas, diffuse large cell B lymphomas and T cell lymphoma were found in 21.1, 26.3, 47.4 and 5.3%, respectively. Nine patients had gastrectomy followed by chemotherapy, 6 patients had palliative resection, 3 patients had chemotherapy only and the remaining patient was treated with Helicobacter pylori eradication. The mean follow-up for all patients was 42.2 months. The 5-year survival rates for stages IE (n=5), IIE (n=4), IIIE (n=6) and IVE (n=4) were 100, 67, 27 and 0%, respectively (p=0.0003). The overall 5 years survival was 48.2%. Primary gastric lymphoma in Jordan shares some epidemiological features with western disease. Jordanian patients are detected and treated after a relatively long delay. Advanced stage at diagnosis correlated with poor outcome. There is a need of an earlier diagnosis and subsequent better care.
