This paper introduces a pathological information network and image analysis system designed by ourselves. The system offers an efficient means for modern medical diagnosis and treatment, teaching, research and management in the department of pathology.
OBJECTIVE: To investigate the relationship between expression of c-erbB-2, CD44v6 and nm23 gene proteins and the clinicopathological features of colorectal carcinomas. METHODS: Immunohistochemical technique was adopted to detect the protein expression of c-erbB-2, CD44v6 and nm23 genes in 92 cases of colorectal carcinomas. Of the 92 cases, 28 cases were followed up for more than 10 years, in which the prognosis was analyzed. RESULTS: Expression of c-erbB-2 and CD44v6 was correlating with UICC staging (P < 0.05), and c-erbB-2 was associated with prominent peritumoral lymphocytic infiltration (P < 0.05). In the 28 cases with followed-up data, univariant analysis revealed that the survival rate was correlated with histological grading, UICC staging, tumor growth pattern, peritumoral lymphocytic infiltration, and expression of c-erbB-2, CD44v6 and nm23. However, Cox stepwise proportional hazards analysis showed that only UICC staging, c-erbB-2 and nm23 status retained significant independently in prospecting prognosis. CONCLUSIONS: Besides UICC III and IV stage, overexpression of c-erbB-2 and decreased expression of nm23 are considered acceptable as the parameters in predicting of poor prognosis in colorectal carcinoma.
OBJECTIVE: To reclassify retrospectively 370 cases of malignant lymphomas. METHODS: According to the WHO new classification, the clinical features and pathology as well as immunophenotype of 370 lymphomas were analysed. RESULTS: In the 370 lymphomas, there were 359 non-Hodgkin's lymphomas (NHL) (97.03%) and 11 Hodgkin's lymphomas (HL) (2.97%). Of the 359 NHL, 246 were B-cell lymphomas (68.52%), 108 T-cell lymphomas (30.08%), 1 each histiocytic lymphoma and follicular dendritic cell sarcoma, and 3 NK cell lymphomas. The extranodal lymphomas were 196 cases (54.6%) and the nodal lymphomas 163 cases (45.4%). The incidence of NHL categories were in proper order as follows: diffuse large B cell lymphoma (173 cases, 48.2%) > peripheral T cell lymphoma (54 cases, 15.0%) > mucosa associated lymphoid tissue (MALT) lymphoma (31 cases, 8.6%) > NK/T cell lymphoma (25 cases, 7.0%) > follicular lymphoma (21 cases, 5.8%) > anaplastic large cell lymphoma (12 cases, 3.3%). CONCLUSION: The results suggested that the study of malignant lymphomas with WHO new classification have important clinical significance.
