Habib, E. E., M. Aziz, and M. Kotb, "Genetic polymorphism of folate and methionine metabolizing enzymes and their susceptibility to malignant lymphoma.", Journal of the Egyptian National Cancer Institute, vol. 17, issue 3, pp. 184-92, 2005 Sep. Abstract

BACKGROUND: Folate and methionine metabolism is involved in DNA synthesis and methylation. Polymorphisms in the genes of folate metabolism enzymes have been associated with some forms of cancer. In the present study, 2 polymorphisms were evaluated for a folate metabolic enzyme, methylene-tetrahydrofolate reductase (MTHFR), and one was evaluated for methionine synthase (MS). The 2 polymorphisms MTHFR 677 C-->T and MTHFR 1298 A-->C, are reported to reduce the enzyme activity, which causes intracellular accumulation of 5, 10- methylene-tetrahydrofolate and results in a reduced incidence of DNA double strand breakage. The MS 2756 A-->G polymorphism also reduces the enzyme activity and results in the hypomethylation of DNA.

PATIENTS AND METHODS: To test this hypothesis, genetic polymorphisms in the folate metabolic pathway were investigated using the DNA from a case-control study on 31 patients having malignant lymphoma from the Oncology Outpatient Clinic of the New Children's Hospital, Cairo University and 30 controls who were actually normal children attending for vaccination to the same hospital.

RESULTS: We found that there is a higher susceptibility with the MTHFR 677CC and MTHFR 1298 AA genotypes (OR=4.3, 95% CI 1.12-16). When those harbor at least one variant allele in either polymorphism of MTHFR they were defined as reference. For the MS 2756 AG genotype polymorphism there was also a higher susceptibility to developing malignant lymphoma (OR=2.6; 95% CI 1.1- 6.4).

CONCLUSION: Results suggest that folate and methionine metabolism may play an important role in the pathogenesis of malignant lymphoma. Further studies to confirm this association and detailed biologic mechanisms are now required.

Khaled, H. M., "Systemic management of bladder cancer in Egypt: revisited.", Journal of the Egyptian National Cancer Institute, vol. 17, issue 3, pp. 127-31, 2005 Sep. Abstract

Bladder cancer is still the most frequent malignant tumor among Egyptian males. It has a peculiar biologic, clinico-pathologic features and responsiveness to chemotherapy profile than that observed in Western countries. The current review aims to demonstrate the present state-of- art in using systemic therapy as part of the management options available to treat such patients at different stages of their disease. Individualizing therapy for these patients based on more rationale basis is the challenge that oncologists must face in the near future.

El-Houseini, M. E., M. S. Mohammed, W. M. Elshemey, T. D. Hussein, O. S. Desouky, and A. A. Elsayed, "Enhanced detection of hepatocellular carcinoma.", Cancer control : journal of the Moffitt Cancer Center, vol. 12, issue 4, pp. 248-53, 2005 Oct. Abstract

BACKGROUND: Tumor markers in the early detection of tumors are promising tools that could improve the control and treatment of tumors. While alpha-fetoprotein (AFP) is a commonly used tumor marker in the detection of hepatocellular carcinoma (HCC), its sensitivity and specificity are insufficient to detect HCC in all patient samples.

METHODS: We compared AFP with serum levels of vascular endothelial growth factors (VEGF and VEGF-A), insulin-like growth factor-2 (IGF-II), and the activity of the lysosomal enzyme alpha-L-fucosidase (AFU) in the sensitivity of detection of HCC and cirrhosis in Egyptian patients.

RESULTS: The sensitivity of tumor detection using AFP was 68.2%. This level of detection was increased to 88.6% when AFP was evaluated in conjunction with AFU. The combined use of AFP and VEGF increased the sensitivity of detection to 95.5% in patients with HCC. The combination of the three markers yielded 100% detection sensitivity. VEGF-A showed a low specificity (20%), and IGF-II showed extremely low sensitivity (4.5%).

CONCLUSIONS: We suggest that AFU or VEGF or both be measured with AFP to improve the detection sensitivity of HCC.
