Histopathologic Findings And Assessment Of Cervical Lymph Node Metastasis In Oral Squamous Cell Carcinoma Of Malaysian Patients, Ismail S. B., Rosnah Binti Zain, Kipli N. P., Abraham T., Ismail M. S., Rahman Z. A. A., Prepageran N., Jalaludin M. A. B.
Histopathologic Findings And Assessment Of Cervical Lymph Node Metastasis In Oral Squamous Cell Carcinoma Of Malaysian Patients, Ismail S. B., Rosnah Binti Zain, Kipli N. P., Abraham T., Ismail M. S., Rahman Z. A. A., Prepageran N., Jalaludin M. A. B.
Prof. Dr. Rosnah Binti Zain
Purpose: To evaluate some histopathologic parameters and relate with the occurrence of cervical lymph node metastasis in oral squamous cell carcinoma (OSCC) in Malaysian patients. Methods: A total of 44 cases of OSCC resected were included. The resected specimens were examined for the OSCC type, degree of differentiation, pattern of invasion (at the tumour invasive front), greatest dimension and the depth of stromal invasion. Where there is no neck resection, the clinical nodal status was obtained from the Oral Cancer database maintained at the University of Malaya Oral Cancer Research and Coordinating Centre (UM-OCRCC) while the histopathologic data were obtained …
Immunoexpression Of Prb And Egfr Using Tissue Microarray (Tma) Technique - A Preliminary Study, Kipli N. P., Cheong C. S., Rosnah Binti Zain, Hamid S., Lim K. P., Abraham T., Ismail M. S., Hussaini H. M.

Prof. Dr. Rosnah Binti Zain
Purpose: To assess the expression of pRb and EGFR in oral epithelial lesions using TMA technique. Methods: Paraffin embedded specimens were selected from the archives of the Diagnostic Laboratories at the Faculty of Dentistry, University of Malaya and Universiti Kebangsaan Malaysia. Selected epithelial areas were cored and developed into tissue microarray blocks. A total of 32 samples for pRb and 50 samples for EGFR were analysed using immunohistochemical techniques. Results: Abnormal pRb staining (1+ or less) was seen in 80% (8/10) OSCC, 38.5% (5/13) dysplastic and 22.2% (2/9) normal/hyperplastic epithelium. Positive EGFR staining was observed in 25/35 (71.4%) OSCC cases …
Expression Of Human B-Defensin-3 In Oral Squamous Cell Carcinoma Using Tissue Microarray - A Preliminary Study, Hussaini H. M., Lim P. K., Rahman R. A., Abraham T., Cheong C. S., Rosnah Binti Zain, Ismail M. S., Nam A. N.
Expression Of Human B-Defensin-3 In Oral Squamous Cell Carcinoma Using Tissue Microarray - A Preliminary Study, Hussaini H. M., Lim P. K., Rahman R. A., Abraham T., Cheong C. S., Rosnah Binti Zain, Ismail M. S., Nam A. N.

Purpose: Human b-Defensin (hBDs) is an epithelial origin, cationic antimicrobial peptides. Their expression is reported in oral mucosa, gingiva and salivary glands. However, their protective role is not well understood. It has been suggested that bacterial and viral infection are an important factors in the process of carcinogenesis. This study investigated the expression of hBD-3 in oral squamous cells carcinoma (OSCC). Methods: 29 OSCC and 23 samples of normal and dysplastic tissues were obtained from Oral Pathology diagnostic laboratory, faculty of Dentistry, UKM and UM. The tissues were arrayed and the expression of hBD-3 was analysed using immunohistochemistry technique. Results: …
