RESUMO
Peritoneal carcinomatosis (ptc) represents advanced malignant disease and has generally been associated with a grim prognosis. Peritoneal surface malignancy is often the major source of morbidity and mortality; it is of major concern in cancer management. Although ptc is categorized as metastatic disease, it represents a special disease pattern considered to be a locoregional disease limited to the abdominal cavity. The combination of cytoreductive surgery (crs) and intraoperative hyperthermic intraperitoneal chemotherapy (hipec) has successfully been used as locoregional treatment for selected patients with ptc from gastric, colorectal, and ovarian cancer; with mesothelioma; and with pseudomyxoma peritonei. In the prophylactic setting, hipec can also be used to prevent ptc in high-risk patients, and the first results of the "second-look" approach are promising. Patient selection-in which the risks of perioperative morbidity and mortality, which are analogous to those for any other major gastrointestinal surgery, are assessed-is of utmost importance. Those risks have to be weighed against the anticipated survival benefit, which depends mainly on tumour biology, extent of disease, and probability of achieving complete crs. The present review discusses the principles of crs and hipec, the most significant recent clinical data, and current perspectives concerning the application of this treatment modality in various malignancies. Ongoing trials and future directions are noted. It appears that the combination of crs and hipec is an indispensable tool in the oncologist's armamentarium.
RESUMO
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.

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.

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.

PURPOSE: Cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is the proper treatment for resectable peritoneal carcinomatosis (PC). The aim of this study was to evaluate the postoperative course and long-term outcome of repeat CS (reCS) plus repeat HIPEC (reHIPEC) in patients with recurrent disease, after primary CS plus primary HIPEC. METHODS: From 2004 to 2012 85 patients were subjected to primary CS + HIPEC. Fourteen of those patients developed recurrent PC and were subjected to reCS+reHIPEC during the same time period. Eligibility criteria included limited extent of the peritoneal disease, and interval of more than 12 months from the primary CS+HIPEC. The origins of the tumors were ovarian cancer (n=7) colorectal cancer (n=3), pseudomyxoma peritonei (n=3), and uterine sarcoma (n=1). RESULTS: At second laparotomy, mean peritoneal cancer index (PCI) was 5.3 + 2.8. Among the 14 procedures, HIPEC was used in all patients. The postoperative mortality was 0% and grade 3-4 postoperative complications occurred in 4 patients. The overall 1-, 2- and 3- year overall survival rate was 90, 40 and 30%, respectively. CONCLUSION: ReCS+reHIPEC is feasible and yields an accepted survival in highly selected patients.

Endometrial cancer (EC) is a common gynecological malignancy. Prognosis depends on 3 main factors: histological subtype, depth of invasion into the myometrium and lymph node involvement. Surgery remains the gold standard of treatment for this cancer. The aim of this article was to review the surgical approach and the new techniques along with the clarification of some controversial aspects concerning the management of advanced disease stages and the role of lymph node dissection. Surgery of EC remains the treatment of choice in the management of early stage disease. The role of lymph node dissection remains controversial.

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.
