Intraperitoneal Chemotherapy and Immunotherapy

Abstract
Treatment failures following putatively curative resections for circumscribed neoplasms are well recognized and the recurrence patterns have been analyzed. These observations compel us to reshape our conceptual model, for such cancers, from one of malignancy as a localized process to that of a regionalized process. Consequently, treatments should evolve to include not only the primary cancer (removedby surgery) but also the entire anatomic region (peritoneal cavity). Regionalized processes command a combined-modality approach to effect cure or, at least, to favorably alter the natural history of the disease. It follows, then, that if for a given neoplasm the available agents are not ideal and, furthermore, that no new agents have been developed in the recent past that offer a hope of improved survival ; we must exploit the agents at hand in the most effective manner.
