Intra-operative diagnosis of breast mass-lesions: comparison of the validity of touch smear preparation and frozen section techniques.

Background: A reliable intra-operative pathological diagnosis is a mandatory before proper surgery of breast cancer. So far, The Frozen Section Technique (FS) is the standard technique with a relatively high level of validity. However, when the special facilities of FS are unavailable, Touch Smears Preparation technique (TSP) could be alternatively adopted.

Evaluation of MIB-1 and p53 overexpression as risk factors in large cell non-Hodgkin lymphoma in adults.

Background: Improvement of current results of therapy for large cell non-Hodgkin lymphoma patients can be achieved by optimization of initial treatment or application of risk-adapted therapy. The international prognostic index ( IPI), introduced to identify high-risk patients, was recently criticized because it was based on clinical risk factors only, ignoring important tumor molecular risk factors and it fails to identify a sector of high-risk patients, who ultimately relapse.

Objective: The aim of this study is to evaluate the value of two tumor biomarkers:MIB-1 and p53 as potential risk factors in diffuse large cell lymphoma.

Lymph node metastasis in breast carcinoma: clinicopathological correlations in 3747 patients.

Background: Histological axillary node involvement (ANI) evaluated by axillary dissection remains the most accurate predictive factor for patients with invasive breast cancer. Axillary node involvement implies the necessity of systemic adjuvant treatment and locoregional irradiation.

Aim Of The Study: Is to detect the relative frequency of node positivity in relation to histopathology through studying a large mastectomy series.

Bladder cancer in Africa: update.

Carcinoma of the bladder is the most prevalent cancer in Egypt and in most African countries. At the National Cancer Institute (NCI), Cairo, it constitutes 30.3% of all cancers.

Cancer patterns in the Middle East--special report from the Middle East Cancer Society.

To update its cancer statistics, the newly established Middle East Cancer Society examined the cancer frequency patterns in Egypt and the Gaza Strip. The results revealed differing overall patterns. For men the highest frequencies were found for lymphoma, bladder cancer and cancers of the oral cavity and pharynx in Egypt, and for lung cancer, leukaemia and lymphoma in Gaza.
