This type of cancer is predominantly benign.  In this study, appendicular NEN tumours in children were investigated. Materials and Methods: This retrospective study was conducted on 540 patients underwent emergency appendectomy for the treatment of clinically suspected appendicitis at the department of p...

Radiotherapy techniques for intracranial tumours

ABSTRACTIntracranial tumours often require radiotherapeutic approaches that differ from other sites. Their specific requirements merit a specialized discussion. A brief review of radiotherapy techniques to treat intracranial tumours is presented with emphasis on the author’s own experience and work, where appropriate. A clinical introduction is presented first followed by a description of bot...

Proteolysis in colorectal cancer.

BACKGROUND The process of metastasis is complex, involving many interrelated stages, including proteolysis. Proteolysis occurs in both normal and pathological processes and involves the breakdown of the extracellular matrix and/or basement membrane by proteolytic enzymes. Normally, proteolysis is tightly controlled by specific endogenous proteinase inhibitors. However, in certain disease proces...
