Brief description The mode of spread of cancer cells from a primary tumour to other parts of the body is still not completely understood, although the lymphatic system is known to be important in this process. Lymph vessels are tiny transparent channels that form a network over the entire body. They transport tissue fluid to regional lymph glands in the neck, armpits, groin, chest and abdomen where the immune response maybe initiated to combat foreign agents such as bacteria and cancer cells. Current knowledge of the anatomy of these tiny vessels is based on work done by Sappey more than a century ago. There is an urgent need to update this work as many of his conclusions have been found to be inaccurate. We will use our pioneering methods of microsurgical tissue transfer- now being used worldwide - and our extensive experience in delineating fine channels, to address some of the basic questions about the anatomical pathways of spread of cancer. We hope to discover for example: why cancer on one side of the back can spread to glands in the opposite groin or armpit, thought by Sappey to be impossible; why cancer on one side of the tongue can spread to lymph glands on the opposite side of the neck; and why there is sometimes swelling of the limbs following lymph gland ablation by surgery or radiotherapy of glands in the groin or armpit. Currently it is thought that the only major connections with the venous system are at the base of the neck. Our initial work has shown unexpected connections with blood vessels in the periphery and unreported lymphatic vessel pathways between the skin and deep tissues. The results of this research will give information that will aid in localizing and treating the spread of malignancies and will underlie future treatment of obstructed lymph vessels that are the cause of painful, disabling swelling (lymphoedema) of the limbs.
