Peritoneal carcinomatosis: intraoperative parameters in open (coliseum) versus closed abdomen HIPEC.

BACKGROUND: Peritoneal carcinomatosis (PC) is associated with a poor prognosis. Cytoreductive surgery (CRS) and HIPEC play an important role in well-selected patients with PC. The aim of the study is to present the differences in the intraoperative parameters in patients who received HIPEC in two different manners, open versus closed abdomen. PATIENTS AND METHODS: The population includes 105 patients with peritoneal carcinomatosis from colorectal, gastric, and ovarian cancer, sarcoma, mesothelioma, and pseudomyxoma peritonei. Group A (n = 60) received HIPEC using the open technique and Group B (n = 45) received HIPEC with the closed technique. The main end points were morbidity, mortality, and overall hospital stay. RESULTS: There were two postoperative deaths (3.3%) in the open group versus no deaths in the closed group. Twenty-two patients in the open group (55%) had grade III-IV complications versus 18 patients in the closed group (40%). There are more stable intraoperative conditions in the closed abdomen HIPEC in CVP, pulse rate, and systolic pressure parameters. CONCLUSIONS: Both methods are equal in the HIPEC procedures. Perhaps the closed method is the method of choice for frail patients due to more stable hemodynamic parameters.

Cytoreductive surgery and HIPEC in recurrent epithelial ovarian cancer: a prospective randomized phase III study.

BACKGROUND: The current treatment of ovarian cancer consists of cytoreductive surgery (CRS) and systemic chemotherapy. The aim of this study was to examine if hyperthermic intraperitoneal chemotherapy (HIPEC) is an alternative modality to treat this category of patients along with a second attempt of surgical resection and second- or third-line systemic chemotherapy afterward. METHODS: In an 8-year period (2006-2013), 120 women with advanced ovarian cancer (International Federation of Gynecology and Obstetrics [FIGO] IIIc and IV) who experienced disease recurrence after initial treatment with conservative or debulking surgery and systemic chemotherapy were randomized into two groups. Group A comprised 60 patients treated with CRS followed by HIPEC and then systemic chemotherapy. Group B comprised 60 patients treated with CRS only and systemic chemotherapy. RESULTS: The mean survival for group A was 26.7 versus 13.4 months in group B (p < 0.006). Three-year survival was 75 % for group A versus 18 % for group B (p < 0.01). In the HIPEC group, the mean survival was not different between patients with platinum-resistant disease versus platinum-sensitive disease (26.6 vs. 26.8 months). On the other hand, in the non-HIPEC group, there was a statistically significant difference between platinum-sensitive versus platinum-resistant disease (15.2 vs. 10.2 months, p < 0.002). Complete cytoreduction was associated with longer survival. Patients with a peritoneal cancer index score of <15 appeared also to have longer survival. CONCLUSIONS: The use of HIPEC along with the extent of the disease and the extent of cytoreduction play an important role in the survival of patients with recurrence in an initially advanced ovarian cancer.

Cytoreductive surgery and HIPEC for peritoneal carcinomatosis in the elderly.

BACKGROUND: The combined treatment of peritoneal carcinomatosis with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy is a rigorous surgical treatment, most suitable for young and good performance status patients. We evaluated the outcomes of elderly patients undergoing CRS and HIPEC for peritoneal carcinomatosis with careful perioperative care. METHODS: All consecutive patients 70 years of age or older who were treated for peritoneal carcinomatosis over the past five years were included. Primary outcomes were perioperative morbidity and mortality. Secondary outcomes were disease-free survival and overall survival. RESULTS: From a pool of 100 patients, with a diagnosis of PC who underwent CRS and HIPEC in our center, we have included 30 patients at an age of 70 years or older and the results were compared to the patients younger than 70 years. The total morbidity rate was 50% versus 41.5% in the group younger than 70 years (NSS).The mortality rate was 3.3% in the elderly group versus 1.43%in the younger group (NSS). Median overall survival was 30 months in the older group versus 38 months in the younger group. CONCLUSION: Cytoreductive surgery and HIPEC for peritoneal carcinomatosis may be safely performed with acceptable morbidity in selected elderly patients.

Peritoneal carcinomatosis 2011; it's about time for chemosurgery.

The aim of this article was to offer a review on the management of peritoneal carcinomatosis (PC) from cancers of different primary origins. Peritoneal surface malignancies have been traditionally regarded as end-stage conditions amenable to merely palliative options, treated with systemic chemotherapy alone with very poor response and a median survival of less than 6 months. The combination of aggressive cytoreductive surgery (CRS), involving peritonectomy procedures and multivisceral resections with hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) to treat microscopic residual disease is a new concept. This method was established with several phase III studies in well selected patients with PC in whom sufficient cytoreduction could be achieved. Despite the need for more high quality phase III studies, there is now a consensus among many surgical teams around the world about the use of this new combination strategy as a standard of care in pseudomyxoma peritonei, peritoneal mesothelioma and colorectal cancer patients. This review summarizes the current status and possible progress in the future.

High-dose melphalan and autologous stem cell transplantation as consolidation treatment in patients with chemosensitive ovarian cancer: results of a single-institution randomized trial.

The role of high-dose chemotherapy (HDCT) in epithelial ovarian cancer (EOC) remains controversial. This study was initiated to compare the efficacy and tolerability of HDCT as a consolidation approach in women with chemosensitive advanced EOC (FIGO stages IIC-IV). Patients who had achieved their first clinical complete remission after six cycles of conventional paclitaxel and carboplatin combination chemotherapy were randomly assigned to receive or not high-dose melphalan. The primary objective was to compare time to disease progression (TTP). A total of 80 patients were enrolled onto the trial. Patients who were randomized to receive HDCT were initially treated with cyclophosphamide 4 g/m(2) for PBPC mobilization. HDCT consisted of melphalan 200 mg/m(2). Of the 37 patients who were allocated to HDCT, 11 (29.7%) did not receive melphalan either due to patient refusal (n=5) or due to failure of PBPC mobilization (n=6). In an intent-to-treat analysis, there were no significant differences between the two arms in TTP (P=0.059) as well as in overall survival (OS) (P=0.38).
