In the past, patients with peritoneal surface malignancy were considered incurable and were only offered palliative treatments. However, in a substantial number of patients, disease progression that is isolated to peritoneum may occur. It has been realised that elimination of peritoneal surface tumours may have an impact on the survival of these cancer patients, in whom a prominent cause of death is peritoneal carcinomatosis. The focus of this PhD. thesis is on the combined treatment of cytoreductive surgery and perioperative intrapersonal chemotherapy for diffuse malignant peritoneal mesothelioma, pseudomyxoma peritonei, colorectal peritoneal carcinomatosis and resectable gastric cancer. Section one describes the major principles of management for peritoneal surface malignancy, covering the historical perspectives, the treatment rationales and the learning curve associated with the combined procedure. Section two is devoted to peritoneal mesothelioma, in trying to examine this disease from its clinical, radiologic and histopathologic aspects. A radiologic classification and a histopathologic staging system for this disease are proposed. In section three, the results of the combined treatment for pseudomyxoma peritonei are presented, including a systematic review of the literature, a case series of 50 patients from our Australian centre and a treatment failure analysis of 402 patients from the Washington Cancer Institute. These studies suggest that a disease-free state is important for long-term survival for patients with pseudomyxoma peritonei. In section four, the current evidence on the combined treatment for colorectaI peritoneal carcinomatosis is demonstrated by conducting a systematic review of the literature and survival and perioperative outcome analyses of two separate patient cohorts. These results suggest that the combined treatment is associated with an improved survival, as compared with historical controls. In the last section, a metaanalysis of the randomised controlled trials on adjuvant intraperitoneal chemotherapy for resectable gastric cancer shows that a significant improvement in survival is associated with hyperthermic intraoperative intraperitoneal chemotherapy alone or in combination with early postoperative intraperitoneal chemotherapy.
