This review covers the following aspects: Cancer associated with asbestos and other fibers: Epidemiology. - Cancer types and location (mesothelioma; bronchogenic carcinoma; cancer of the upper respiratory tract; abdominal cancer). - Experimental asbestos cancer. - Other kinds of fibers and cancer (wool and cotton; glass; talc; others). - Cancer determining or influencing factors (individual predisposition; species susceptibility; type of material; shape and size of fibers; smoking). - Preneoplastic signs in man (fibrosis; ferruginous bodies; pleural plaques; milky spots). - Preneoplastic development in animals. - Fiber effects on cell cultures (macrophages; fibroblasts). Cancer associated with schistosomiasis: Epidemiology. - Patient age and cancer latency. - Pathology. - Foreign body reaction and preneoplastic development. Scar cancer. Foreign body cancer: In man. - Experimental (species differences in susceptibility; individual genetic differences in tumor incidence and latency; influence of sex, age, nutrition; tumor histopathology and ultrastructure; tumor growth, invasiveness, metastases, transplantability, immunology; search for tumor viruses). - Properties of foreign body materials in relation to tumorigenicity (chemical and physical properties; size and shape; surface properties; porosity). - Investigations and findings concerning the origin of foreign body sarcomas (the foreign body reaction; search for foci of tumor origin; an analytical method; monoclonal tumor origin; heterogenicity of carcinogenic events; surface dependency; identification of originator cells; time and location of the emergence of tumor originator cells; the carcinogenic initiation event; surface-independent and dependent preneoplastic maturation; the carcinogenic role of the foreign body). - Earlier hypotheses and theories in the light of new experimental findings. The results of experimental foreign body tumorigenesis in relation to foreign body-, asbestos-, schistosomiasis-, and scar-cancer in man. (Common factors of promotion; differences regarding induction mechanisms, cells of origin, latencies, frequencies; immune defense). Consequences for prevention: Asbestos cancer. - Fiber cancer. - Schistosomiasis cancer. - Foreign body cancer (assessing the peril in man; testing of materials for carcinogenicity; recommendations).

The peritoneal membrane, formed by a single layer of mesothelial cells, lines the largest cavity of the human body. Anatomic structures of the peritoneal cavity, along with resident leukocyte populations, play an important role in the defense against microorganisms invading by breaching the gut integrity or ascending through the female genital tract. Local immune mechanisms in the peritoneal cavity are also important in patients undergoing peritoneal dialysis and in women with endometriosis. There is now extensive evidence demonstrating the significance of peritoneal immune mechanisms in the control of metastatic spread. Leukocytes belonging to both the innate and adaptive immune systems are present in the peritoneal cavity of normal subjects as well as in patients with intra-abdominal cancer. There is now increased understanding of the mechanisms that not only allow the tumor cells to escape the detection and destruction by the host immune system, but also to use the inflammatory mechanisms to promote tumor growth and spread inside the peritoneal cavity. Malignant ascites represents a model for the study of the interaction between tumor cells and the host immune system as well for the analysis of the tumor microenviroment. The peritoneal immune system may be stimulated by intraperitoneal administration of biologic agents. This peritoneal immunotherapy may be used for palliation of malignant ascites, or as a consolidation strategy in patients with minimal residual disease.
