Hyperthermic intraperitoneal chemotherapy with oxaliplatin and without adjuvant chemotherapy in stage IIIC ovarian cancer.
ABSTRACT To assess the feasibility and efficacy of cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) without adjuvant chemotherapy for relapsed or persistent advanced ovarian cancer.
This observational study included stage IIIC ovarian cancer patients due to undergo CRS (interval debulking or recurrent surgery) followed by HIPEC with oxaliplatin (460 mg/m2) for 30 min.
Twenty-two patients (12 interval debulking procedures and 10 recurrence procedures) were enrolled between September 2003 and September 2007. HIPEC was not performed in four patients because of operative findings. No patient received adjuvant chemotherapy after HIPEC. Patients were followed up routinely until recurrence or death. Median peritoneal cancer index at surgery was 6 (range: 1-18). Before HIPEC, all patients had completeness of cytoreduction scores of 0 or 1. Median length of hospital stay was 21 days (range 13-65). Ten patients (55.6%) had CTCAE grade 3-4 toxicity, including three patients (16.7%) requiring reoperation. No postoperative mortality was observed. With a median follow-up of 38 months (CI 95% 23.8-39.2), median overall survival was not reached. The 3-year overall survival rate was 83% (CI 95% 54-95). Median disease-free survival was, respectively, 16.9 months (CI 95% 10.2-23.2) and 10 months (CI 95% 4.5-11.3) for patients undergoing interval debulking or recurrence surgery.
HIPEC without adjuvant chemotherapy is both feasible and safe, but with a high rate of grade 3-5 toxicity. Survival results are encouraging but should be confirmed in a randomized trial.

ABSTRACT: The management and the outcome of peritoneal metastases or recurrence from epithelial ovarian cancer are presented. The biology and the diagnostic tools of EOC peritoneal metastasis with a comprehensive approach and the most recent literatures data are discussed. The definition and the role of surgery and chemotherapy are presented in order to focuse on the controversial points. Finally, the paper discusses the new data about the introduction of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of advanced epithelial ovarian cancer.Gastroenterology Research and Practice 01/2012; 2012:541842. · 1.62 Impact Factor

ABSTRACT: The study investigated possible mechanisms by which second-generation taxanes, established as significantly more effective than paclitaxel in vitro, suppress a rat lymphoma model in vivo. The studied mechanisms included taxane pharmacokinetics, expression of genes dominating their metabolism (Cyp3a1/2) and transport (Abcb1) and genes controlling tumour angiogenesis (growth factors and receptors). SB-T-1214, SB-T-12854 and IDN5109 suppressed rat lymphoma more effectively than paclitaxel, SB-T-12851, SB-T-12852, SB-T-12853 or IDN5390 as well as P388D1 leukaemia cells in vitro. The greater anti-lymphoma effects of SB-T-1214 in rats corresponded to a higher bioavailability than with SB-T-12854, and lower systemic toxicity of SB-T-1214 for rats reflected its lower cytotoxicity for P388D1 cells in vitro. Suppression of Abcb1 and CYP3a1 expression by SB-T-1214 and IDN5109 could partly explain their anti-lymphoma effects, but not that of SB-T-12854. Growth factors genes Egf, Fgf, Pdgf, and Vegf associated with tumour angiogenesis had significantly lower expression following treatment with anti-lymphoma effective IDN5109 and their receptors were unaffected, whereas inefficient IDN5390 increased expression of the most important Vegf. The effective SB-T-12854 inhibited Egf, Egfr, Fgfr and Pdgfr expression, while the ineffective SB-T-12851, SB-T-12852 and SB-T-12853 inhibited only Egf or Egfr expression. Vegfr expression was inhibited significantly by SB-T-12851 and SB-T-12854, but effect of SB-T-12851 was compromised by induced Vegf expression. The very effective SB-T-1214 decreased the expression of Vegf, Egf and all receptors most prominently indicating the possible supporting role of these genes in anti-lymphoma effects. In conclusion, SB-T-1214, SB-T-12854 and IDN5109 are good candidates for further study.Investigational New Drugs 03/2011; 30(3):991-1002. · 3.50 Impact Factor

ABSTRACT: Although standard treatment for advanced epithelial ovarian cancer (EOC) consists of surgical debulking and intravenous platinum- and taxane-based chemotherapy, favorable oncological outcomes have been recently reported with the use of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The aim of the study was to analyze feasibility and results of CRS and HIPEC in patients with advanced EOC. This is an open, prospective phase 2 study including patients with primary or recurrent peritoneal carcinomatosis due to EOC. Thirty-nine patients with a mean (SD) age of 57.3 (9.7) years (range, 34-74 years) were included between September 2005 and December 2009. Thirty patients (77%) had recurrent EOC and 9 (23%) had primary EOC. For HIPEC, cisplatin and paclitaxel were used for 11 patients (28%), cisplatin and doxorubicin for 26 patients (66%), paclitaxel and doxorubicin for 1 patient (3%), and doxorubicin alone for 1 patient (3%). The median intra-abdominal outflow temperature was 41.5°C. The mean peritoneal cancer index (PCI) was 11.1 (range, 1-28); and according to the intraoperative tumor extent, the tumor volume was classified as low (PCI <15) or high (PCI ≥15) in 27 patients (69%) and 12 patients (31%), respectively. Microscopically complete cytoreduction was achieved for 35 patients (90%), macroscopic cytoreduction was achieved for 3 patients (7%), and a gross tumor debulking was performed for 1 patient (3%). Mean hospital stay was 23.8 days. Postoperative complications occurred in 7 patients (18%), and reoperations in 3 patients (8%). There was one postoperative death. Recurrence was seen in 23 patients (59%) with a mean recurrence time of 14.4 months (range, 1-49 months). Hyperthermic intraperitoneal chemotherapy after extensive CRS for advanced EOC is feasible with acceptable morbidity and mortality. Complete cytoreduction may improve survival in highly selected patients. Additional follow-up and further studies are needed to determine the effects of HIPEC on survival.International Journal of Gynecological Cancer 05/2012; 22(5):778-85. · 1.94 Impact Factor
