Management of localized primary gastric B lymphoma (PGL) remains controversial. The aim of this study is to compare two treatments: chemotherapy alone and surgery plus chemotherapy.
Materials
Records of all patients with a diagnosis of gastric lymphoma and which were treated in the National Institute of Oncology, between 1999 and 2006, were reviewed and patients fulfilling the following criteria were included in this study: histologically proven large-cell B lymphoma of the stomach; complete clinical information stage I/II disease according to the Musshoff staging; patients who received surgery followed by chemotherapy (group I) or chemotherapy alone (group II).
Results
This study included 82 patients who were treated for cancer in our Institute. All clinical and pathological features were similar between the two groups, except that patients of group-I had significantly more stage II disease (P = 0.023) than that of group II. Among the 52 patients who could be evaluated for response to chemotherapy, there were 45 who had complete response to treatment, 3 had partial response to the treatment and 4 had progressive disease. The projected 5-year relapse-free survival (RFS) and overall survival (OS) of group I were 86.69% (95% CI, 57.9 - 97.7%) and 90.0% (95% CI, 58.0 - 97.8%), respectively. And the projected 5-year relapse-free survival RFS and OS of group II were 86.67% (95% CI, 57.0 - 88.2%) and 93.33% (95% CI, 73.3 - 98.7%) respectively. There were no statistically significant differences in RFS (P = 0.485) and OS (P = 0.551) between the two groups.
Conclusion
Our data suggest that chemotherapy alone may be a reasonable alternative treatment for stage I/II gastric large-cell lymphoma but this result must be confirmed by prospective randomized clinical trials.
