ABSTRACT
Peritoneal carcinomatosis (PC) is a common form of tumour metastasis stemming from gastrointestinal and colorectal cancers. For a long time, PC has been considered a terminal clinical condition treated only with palliative systemic chemotherapy and associated with very limited results. During the last decade, the treatment of advanced colorectal disease has greatly improved with the emergence of new chemotherapy drugs and biological agents. However, the median survival rates still do not surpass 24 months, even though most of these studies correspond to groups of patients with metastatic disease to the liver and/or lung. The approach and development of cytoreductive radical surgery (CRS) + hyperthermic intraperitoneal chemotherapy (HIPEC) are based on performing radical surgery of the entire visible tumour within the abdomen/peritoneum, followed immediately by HIPEC, which acts upon microscopic tumour that remains present after surgery and which is responsible for the persistence or relapse of peritoneal disease. Peritonectomy procedures are demanding surgical techniques that permit elimination of the tumour present in the peritoneal lining and any other organs and/or structures that are infiltrated. The synergistic effect of hyperthermia and chemotherapy has been well documented. Hyperthermia increases the cytotoxicity of some cytostatic agents and increases the penetration of certain drugs into the neoplastic cells. The prognosis for patients with PC who undergo combined treatment correlates with the volume of PC (tumour burden) measured as the Peritoneal Cancer Index (PCI) and the ability to perform a CRS, to completely eliminate the gross tumour. At least one phase III study and an important number of phase II studies have shown that CRS + HIPEC provides important survival benefits for patients with PC of colorectal origin. The combination of CRS + HIPEC is indicated for patients with good general health, a low PCI, absence of extra-abdominal metastasis and who can, technically, undergo CRS. The early identification of this group of patients, rapid referral to centres specialised in CRS + HIPEC, together with the correct application of this treatment, are key in achieving the best results (AU)
