The Effect of Surgery on the Prognosis of Gastric Lymphoma: A Meta-analysis.

Surgery is an effective clinical approach that has been used for the treatment of gastric lymphoma. However, its specific effect on the prognosis of patients with gastric lymphoma remains largely unknown. The current meta-analysis aimed to identify the effect of surgery on the prognosis of gastric lymphoma. We searched the MEDLINE, Embase, and Cochrane Central databases to obtain relevant studies investigating the influence of surgery on overall survival (OS) and relapse-free survival (RFS). We extracted the hazard ratios (HRs) and associated 95% confidence intervals (CIs) of each included report for pooled analysis. We assessed heterogeneity (I2 statistic) and funnel plots to select the data models and evaluate publication bias. Ultimately, we included 12 studies containing 26 comparisons in the current quantitative meta-analysis. The analysis revealed that surgery had no significant effect on OS (HR .83, P = .13) or RFS (HR .78, P = .08). However, subgroup analysis revealed that the effect of surgery on OS differed significantly between the surgery plus conservative therapy subgroup and the conservative therapy alone groups, with HR = .69 (P = .01). No significant publication bias was detected regarding the main outcomes. Surgery had a limited effect on the prognosis of patients with gastric lymphoma. However, the use of surgery as an additional therapy may confer potential benefits. This was an interesting research direction, and additional high-quality, large-scale randomized controlled trials should be conducted.

Factors in the prognosis of gastric lymphoma

The tumor-nodes-metastases (TNM) staging classification for gastric carcinoma was applied to 50 consecutive cases of primary gastric lymphoma. Survival statistics were obtained for each respective stage category and were remarkably similar to survival statistics for gastric carcinoma. Overall, patients with primary gastric lymphoma have a much better prognosis for survival than patients with gastric carcinoma since the latter present with far more frequent serosal penetration and nodal and distant metastases. Penetration of gastric lymphoma beyond the serosa is associated with a significantly decreased 5-year survival rate from 88 to 24%, and the presence of perigastric nodal involvement decreased the survival rate from 88 to 32%.
