Hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) is now an entire part of treatment of peritoneal dissemination of colorectal malignancy, and it's possible to hope prolonged survival. This treatment is more and more codified. Four indications are recognized by some tree national evaluation committees: the French ANAES, the British NICE and the Canadian CEPO: colorectal carcinoma, carcinoma of the appendix, pseudomyxoma peritonei and mesothelioma. Last big published series results show a decrease of morbidity and mortality and interest of using new drugs like oxaliplatine. Indications have to be more homogeneous and based on evidences.

- "However, due to partial reflection of electromagnetic waves by the body contour and the electric properties of human tissue, it is difficult for the energy of electromagnetic waves to concentrate in the deep tumor layers. This may cause nonuniform heat distribution.2,3 In addition, it is hard to measure and maintain a constant temperature accurately at the deeper layers, which also limits the application of thermotherapy in the treatment of cancer.

ABSTRACT: The purpose of this study was to develop intraperitoneal hyperthermic therapy based on magnetic fluid hyperthermia, nanoparticle-wrapped cisplatin chemotherapy, and magnetic particles of albumin. In addition, to combine the multiple-killing effects of hyperthermal targeting therapy, chemotherapy, and radiotherapy, the albumin-nanoparticle surfaces were linked with radionuclide (188)Re-labeled folic acid ligand ((188)Re-folate-CDDP/HSA).
Human serum albumin was labeled with (188)Re using the pre-tin method. Reaction time and optimal conditions of labeling were investigated. The particles were intravenously injected into mice, which were sacrificed at different time points. Radioactivity per gram of tissue of percent injected dose (% ID/g) was measured in vital organs. The biodistribution of (188)Re-folate-CDDP/HAS magnetic nanoparticles was assessed.
Optimal conditions for (188)Re-labeled folate-conjugated albumin combined with cisplatin magnetic nanoparticles were: 0.1 mL of sodium gluconate solution (0.3 mol/L), 0.1 mL of concentrated hydrochloric acid with dissolved stannous chloride (10 mg/mL), 0.04 mL of acetic acid buffer solution (pH 5, 0.2 mol/L), 30 mg of folate-conjugated albumin combined with cisplatin magnetic nanoparticles, and (188)ReO(4) eluent (0.1 mL). The rate of (188)Re-folate-CDDP-HSA magnetic nanoparticle formation exceeded 90%, and radiochemical purity exceeded 95%. The overall labeling rate was 83% in calf serum at 37°C. The major uptake tissues were the liver, kidney, intestine, and tumor after the (188)Re-folate-CDDP/HSA magnetic nanoparticles were injected into nude mice. Uptake of (188)Re-folate-CDDP/HSA magnetic nanoparticles increased gradually after injection, peaked at 8 hours with a value of 8.83 ± 1.71, and slowly decreased over 24 hours in vivo.
These results indicate that (188)Re-folate-CDDP/HSA magnetic nanoparticles can be used in radionuclide-targeted cancer therapy. Surface-modified albumin nanoparticles with folic acid ligand-labeled radionuclide ((188)Re) were successfully prepared, laying the foundation for a triple-killing effect of thermotherapy, chemotherapy, and radiation therapy.

ABSTRACT: To develop a treatment strategy for peritoneal carcinomatosis using a combination of extended peritoneal resections, local destructive procedures and hyperthermic intraperitoneal chemotherapy creates great concern between healthcare workers involved in these procedures. New professional risks exist: risk of exposure to cytotoxic drugs, environmental risks (inhalation of smoke, aerosolization of chemotherapy agents). Information, education and training of healthcare workers is mandatory in order to ensure proper evaluation, prevention, and management of professional exposure risks in coordination with the occupational health office.

ABSTRACT: Cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy (HIPEC) is now the reference technique for limited peritoneal carcinomatosis (PC). Operative mortality is actually at 3 or 4%, and decrease as morbidity. Together, they did not limit acceptation of HIPEC. However, one of the major limitation of this aggressive treatment is that patient can be afraid to impair overall quality of life (QoL). The aim of this article was to assess QoL in patients at least 12 months after HIPEC using Oxaliplatin.
Patients completed a questionnaire before and after surgery at 1, 3, 6 and 12 months. QoL was assessed with the EORTC QLQ-C30 questionnaire. RESULTATS: Between September 2006 and October 2008, 32 of 35 patients who had undergone HIPEC were interviewed. PC originated in primary lesions of the colon/rectum (N = 17), ovary (N = 3), stomach (N = 3), appendix (N = 2), mesothelium (N = 2), pseudomyxoma peritonei (N = 3) and primary carcinoma of peritoneum (N = 2). The percentage of patients completing the questionnaire at each time point was: baseline = 87% (N = 28); 1 and 3 months = 46% (N = 15); 6 months = 62% (N = 20); and 12 months = 59% (N = 19). Morbidity and mortality were respectively 35 and 5%. Median hospital stay was 19 days. QoL score had decreased considerably in 60% of patients in the early postoperative assessment period after HIPEC (1 month), as compared with baseline score. Forty five per cent had reported significant pain and limitations on physical functioning. QoL score had returned to baseline at 3 months in 53,3% of patients: 20% reported lack of energy and fatigue. Fifty-five and 73% of patients had recovered their overall QoL at 6 and 12 months, respectively. Also, psychosocial problems, diarrhea and constipation, and peripheral neuropathy of oxaliplatin were reported in 20% of survivors over the course of the first year after HIPEC.
Short-term QoL with physical and functional well-being are impaired in the first few months after surgery plus HIPEC using oxaliplatin. Long-term QoL returns to baseline at 3 months; however 20% of patients still report psychosocial problems, gastrointestinal symptoms and oxaliplatin-induced neuropathy. It is useful and important for patients to see this HIPEC QoL data at the time of consultation before treatment.
