Early and long-term postoperative management following cytoreductive surgery and hyperthermic intraperitoneal...

Peritoneal surface malignancies have been traditionally regarded as end-stage conditions amenable to merely palliative options. The combination of aggressive cytoreductive surgery (CRS), involving peritonectomy procedures and multivisceral resections, with intra-operative hyperthermic intra-peritoneal chemotherapy (HIPEC) and/or early postoperative intra-peritoneal chemotherapy (EPIC) to treat the microscopic residual tumor is a new concept. In recent years, promising results have been reported for peritoneal mesothelioma and carcinomatosis of gastrointestinal and gynaecologic origin treated by this combined protocol. However, CRS with HIPEC and/or EPIC is a complex procedure associated with high rates of potentially life-threatening complications. Furthermore, disease progression following comprehensive treatment is not uncommon and represents a relevant cause of treatment failure. The present paper reviews the available information on early postoperative management and long-term follow-up in patients treated with CRS and intraperitoneal chemotherapy. The peculiar clinical and biological alterations that can be expected during an uncomplicated postoperative course, as compared to standard digestive surgery, are discussed. Early recognition and appropriate management of the most common adverse events are addressed, in order to minimize the impact of treatment-related morbidity on survival and quality of life results. Since re-operative surgery with additional HIPEC, has proven to be useful in selected patients with recurrent disease, long-term surveillance aiming at early detection of postoperative disease progression has become a relevant issue. Current results on follow-up investigations are presented.
