Cancer of Oral Cavity Abutting the Mandible; Predictors of Loco-regional Failure.

Aim Of Work: : The purpose of this study is to analyze the causes of Loco-regional failure in 51 patients with tumors of the oral cavity abutting the mandible.

Patients And Methods: This cross-sectional study (27 patients were operated upon in the retrospective section and 24 patients in the prospective section of the study) was done in the department of Surgical Oncology, National Cancer Institute, Cairo University, from January 2003 to January 2008. Fifty-one patients, with oral cavity cancerous lesions abutting the mandible, were operated upon by segmental mandibulectomy en-bloc with primary tumor resection in addition to modified radical or selective neck dissection according to the status of the cervical lymph nodes.

Locally advanced tumors of the scalp: the Egyptian National Cancer Institute experience.

Background: It is well recognized that recurrent disease can occur following malignancy in the head and neck region. This is particularly true for basal cell & squamous cell carcinoma, whereby recurrence may occur many years following initial surgery or other modalities. We report here on skin malignancy occurring in the scalp with skull invasion down to the dura mater.
