Filter methods and radio-labelled tumour cells provided the most useful way of following cell movement. Concludes spread of tumour cells to the port-site is more likely in the presence of disseminated disease, as well as with inappropriate surgical technique. Metastasis may be reduced by the use of intraperitoneal lavage and appropriate surgical technique. / Thesis (M.D)--University of Adelaide, Dept. of Surgery, 1999
