To investigate the expression pattern of p27 protein in primary gastric lymphomas.Immunostaining for the p27 protein was performed in 16 cases of low grade mucosa-associated lymphoid tissue (MALT) lymphomas and 16 cases of high grade B-cell lymphomas of the stomach.All low grade MALT lymphomas were positive, however all high grade lymphomas were negative forp27 protein. Most of the monocytoid cells in the low grade lymphoma were unstained.Loss of p27 protein expression is well correlated with histologic grade and appears to be associated with the high grade transformation seen in primary gastric lymphomas.
