Abstract

Introduction: PANCREATIC CANCER has not been well studied, especially in developing countries.
Materials and Methods: We studied the variations in genetic mutations in pancreatic adenocarcinoma between Moroccan and EGYPTian populations. The MOLECULAR PATHOLOGY of 30 tumors from a large hospital in Casablanca, MOROCCO were examined and compared with the findings of 44 tumors from the Gharbiah Governate in EGYPT. K-RAS mutations in codons12 and 13 in addition to P53 mutations in exons 5-8 were evaluated.Results: Overall, differences in the rates of K-RAS mutations were not statistically significant (48.00 and 34.09%, respectively); however differences in rates of P53 mutations were statistically significant with P53 mutations more common in Moroccan tumors than in EGYPTian tumors (46.67 and 16.28%, respectively). G®T mutations of the K-RAS gene were most commonly seen EGYPTian tumors, whereas G®A mutations were the most common type of mutations in Moroccan tumors. Logistic regression analysis showed that a P53 mutation in any exon as well as a P53 mutation in exon 5 predicted the country of residence and those mutations occurred more frequently in Moroccan patients.Conclusion: Our study shows that differences exist within the Arab population in the MOLECULAR PATHOLOGY of both the K-RAS and P53 genes. Further studies are necessary to clarify the differences in molecular pathways of PANCREATIC CANCER in the Middle East and to investigate the role of environmental and/or genetic factors related to those pathways.
