Primary Non-Hodgkin’s Lymphoma of Stomach: To Report 54 Patients and Analysis of Major Reported Series

Abstract

Introduction. This study aimed to report the characteristics, prognostic factors, and treatment outcomes of 54 patients with primary gastric lymphoma.Materials and Methods. This retrospective study was carried out by reviewing the medical records of 54 adult patients diagnosed at a tertiary academic hospital. All the patients were treated with curative intent. Forty-four patients (81.5%) underwent gastrectomy followed by adjuvant chemotherapy and/or radiotherapy, whereas 10 ones (18.5%) were treated with chemotherapy alone or with radiotherapy.Results. The study was conducted on 25 males and 29 females with the median age of 50 years. Diffuse large B-cell lymphoma (DLCL) (67%) and Mucosa Associated Lymphoid Tissue (MALT) lymphoma (26%) were the most common histologic types. Besides, 36 (59%), 16 (30%), 5 (9%), and 1 (2%) patients were in stages I, II, III, and IV, respectively. The 5-year disease-free survival and overall survival were 64.7% and 67%, respectively. In univariate analysis for overall survival, International Prognostic Index (IPI) (), the WHO performance status (), Ann Arbor stage (), age (), and LDH serum level () were the prognostic factors.Conclusion. Gastric lymphoma tends to present in early stage of the disease and has a favorable outcome.

Immunohistochemistry and scoring of Ki-67 proliferative index and p53 expression in gastric B cell lymphoma from Northern African population: a pilot study

“…However, it was lower in other Asian countries; it doesn't exceed the 50 years in china (19) and 42 years in Iraq (20). The M/F sex ratio in our studied population is higher than what has been reported from china (1.18) (21) and France (1.24) (22), but it is contrast to the study by Ansari et al, which showed a female predominance (23). In general, GL more frequently involves antrum, corpus, and cardia (24).…”

“…In our series of 20 patients, most of the patients (60%), antrum was the main involved site, accounting for 60% cases. The histology types in this study had shown similar patterns of frequency compared to report of Al-Shehabi et al (25) and Xie et al (16), in which MALT was the dominant histology types, while reports from Jordan (26) and Iran (23) have shown a predominance of DLBCL.…”
