Simultaneous Surgical Approach with Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in Patients with Concurrent Peritoneal and Liver Metastases of Colon Cancer Origin. J Clin Med 2023; 12:jcm12113860. [PMID: 37298054 DOI: 10.3390/jcm12113860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Revised: 05/07/2023] [Accepted: 05/27/2023] [Indexed: 06/12/2023] Open
Abstract
Background: Simultaneous liver resection and peritoneal cytoreduction with hyperthermic intraperitoneal chemotherapy (HIPEC) remains controversial today. The aim of the study was to analyze the postoperative outcomes and survival of patients with advanced metastatic colon cancer (peritoneal and/or liver metastases). Methods: Retrospective observational study from a prospective maintained data base. Patients who underwent a simultaneous peritoneal cytoreduction and liver resection plus HIPEC were studied. Postoperative outcomes and overall and disease free survival were analyzed. Univariate and multivariate analyses were performed. Results: From January 2010 to October 2022, 22 patients operated with peritoneal and liver metastasis (LR+) were compared with 87 patients operated with peritoneal metastasis alone (LR-). LR+ group presented higher serious morbidity (36.4 vs. 14.9%; p: 0.034). Postoperative mortality did not reach statistical difference. Median overall and disease free survival was similar. Peritoneal carcinomatosis index was the only predictive factor of survival. Conclusions: Simultaneous peritoneal and liver resection is associated with increased postoperative morbidity and hospital stay, but with similar postoperative mortality and OS and disease free survival. These results reflect the evolution of these patients, considered inoperable until recently, and justify the trend to incorporate this surgical strategy within a multimodal therapeutic plan in highly selected patients.

Effect of hyperthermic intraperitoneal chemotherapy in combination with cytoreductive surgery on the prognosis of patients with colorectal cancer peritoneal metastasis: a systematic review and meta-analysis. World J Surg Oncol 2022; 20:200. [PMID: 35701802 PMCID: PMC9195265 DOI: 10.1186/s12957-022-02666-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Accepted: 05/28/2022] [Indexed: 11/30/2022] Open
Abstract
Background Peritoneal metastasis often occurs in patients with colorectal cancer peritoneal metastasis, and the prognosis is poor. A large body of evidence highlights the beneficial effects of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) on survival, but to date, there is little consensus on the optimal treatment strategy for patients with colorectal cancer peritoneal metastasis. The purpose of this study is to evaluate the impact of CRS + HIPEC on survival and provide reference for the treatment of patients with colorectal cancer peritoneal metastasis. Methods This systematic review and meta-analysis is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The PubMed, Embase, Cochrane, Web of Knowledge, and ClinicalTrials.gov databases were screened from inception of the review to March 11, 2022. Ten studies were included in qualitative and quantitative analysis. Results A total of 3200 patients were enrolled in the study, including 788 patients in the CRS and HIPEC groups and 2412 patients in the control group, of which 3 were randomized controlled trials and 7 were cohort studies. The 3 randomized controlled studies were of high quality, and the quality scores of the 7 cohort studies were all 7 or above, indicating high quality. The results showed that the OS of CRS + HIPEC group was higher than that of control group (HR: 0.53, 95% CI: 0.38–0.73; P < 0.00001, I2 = 82.9%); the heterogeneity of the studies was large. The subgroup analysis showed that the OS of CRS and HIPEC group was higher than that of PC group (HR: 0.37, 95% CI: 0.30–0.47; P = 0.215, I2 = 31%) and higher than that in CRS group (HR: 0.73, 95% CI: 0.49–1.07; P = 0.163, I2 = 44.8%); the heterogeneity of the studies was low. In the OPEN group, the OS of THE CRS and HIPEC groups was higher than that in the control group (HR: 0.51, 95% CI: 0.38–0.70; P = 0.353, I2 = 3.9%); OPEN group showed lower heterogeneity. The OS of 60–100-min group was higher than that in the control group (HR: 0.65, 95% CI: 0.49–0.88; P = 0.172, I2 = 37.4%); the heterogeneity of the studies was low. Sensitivity analysis showed that there was no significant difference in the results of the combined analysis after each study was deleted. The results of publication bias showed that the P-value of Egger and Begg tests was 0.078 > 0.05, indicating that there is no publication bias. Conclusions CRS + HIPEC can improve the survival rate of patients with colorectal cancer peritoneal metastasis

Abstract
Peritoneal carcinomatosis, as well as the presence of liver metastases from colorectal cancer, has been long considered as the sign of a systemic disease, transforming the patient into a candidate for palliation and best supportive care. However, in recent decades, progress in the field of medical and surgical oncology has allowed scientists worldwide to produce curative therapeutic strategies for these cases such as hyperthermic intraperitoneal chemotherapy (HIPEC) or extended liver resection. In addition, the association of these two therapies has also been performed with encouraging results. The aim of the current study was to review articles published thus far in regard to the association of these two therapeutic strategies, in order to identify which cases can benefit the most, which is the most efficient agent or combination of agents, and whether these types of therapy should be performed as monotherapy or as a two-stage procedure.

Liquid biopsy in peritoneal fluid and plasma as a prognostic factor in advanced colorectal and appendiceal tumors after complete cytoreduction and hyperthermic intraperitoneal chemotherapy. Ther Adv Med Oncol 2020; 12:1758835920981351. [PMID: 33425029 PMCID: PMC7758863 DOI: 10.1177/1758835920981351] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Accepted: 11/26/2020] [Indexed: 12/22/2022] Open
Abstract
Background Positive cytology has been identified as an independent negative prognostic factor in patients with peritoneal metastases (PM) of colorectal origin. Liquid biopsy in plasma may detect increasing levels of circulating tumor DNA (ctDNA) and could help predict systemic relapse in patients with colorectal cancer, but little is known about the role of liquid biopsy in peritoneal fluid. The aim of this study was to evaluate the prognostic value of peritoneal fluid and plasma liquid biopsy in patients undergoing complete cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CC-HIPEC). Methods A longitudinal prospective study was designed in patients with KRAS-mutated colorectal or appendiceal primary tumor, including PM of colorectal origin, pseudomyxoma peritonei and patients at high risk of developing PM (selected for second-look surgery). Eleven patients were recruited according to inclusion and exclusion criteria. ctDNA from plasma and peritoneal fluid before and after HIPEC was studied by droplet digital PCR looking for KRAS mutation. A close follow-up was scheduled (mean of 28.5 months) to monitor for systemic and peritoneal recurrences. Results All patients with positive plasma postHIPEC had systemic relapse and four patients died as a result, while those with negative plasma postHIPEC did not relapse. Patients with negative peritoneal ctDNA after CC-HIPEC did not present peritoneal relapse. Of six patients with positive peritoneal ctDNA postHIPEC, two presented peritoneal recurrence and four systemic relapses. Conclusions Treatment with CC-HIPEC does not always neutralize ctDNA in peritoneal fluid, and its persistence after treatment may predict adverse outcome. Despite being a proof of concept, an adequate correlation between liquid biopsy in plasma and peritoneal fluid with both systemic and peritoneal relapse has been observed.

Abstract
Modern management of colorectal cancer (crc) with peritoneal metastasis (pm) is based on a combination of cytoreductive surgery (crs), systemic chemotherapy, and hyperthermic intraperitoneal chemotherapy (hipec). Although the role of hipec has recently been questioned with respect to results from the prodige 7 trial, the role and benefit of a complete crs were confirmed, as observed with a 41-month gain in median survival in that study, and 15% of patients remaining disease-free at 5 years. Still, crc with pm is associated with a poor prognosis, and good patient selection is essential. Many questions about the optimal management approach for such patients remain, but all patients with pm from crc should be referred to, or discussed with, a pm surgical oncologist, because cure is possible. The objective of the present guideline is to offer a practical approach to the management of pm from crc and to reflect on the new practice standards set by recent publications on the topic.

Survival after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for colorectal peritoneal metastases: A systematic review and discussion of latest controversies. Surgeon 2020; 19:310-320. [PMID: 33023847 DOI: 10.1016/j.surge.2020.08.016] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Revised: 08/14/2020] [Accepted: 08/31/2020] [Indexed: 12/24/2022]
Abstract
INTRODUCTION Peritoneal metastases confer the worst survival amongst all sites of metastatic colorectal cancer. The adoption of cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has become an option for patients with isolated colorectal peritoneal metastases (CRPM). The aim of this study was to evaluate the outcomes following CRS and HIPEC for CRPM from published high volume cohort studies and to highlight the latest controversies and future directions of CRPM treatment. MATERIALS AND METHODS A systematic review was performed on published studies on the treatment outcomes of CRS and HIPEC for colorectal peritoneal metastases. RESULTS Twenty studies met the inclusion criteria for the systematic review. The median survival for all patients ranged from 14.6 to 60.1 months. The 5-year overall survival ranged from 23.4% to 52%. For patients with complete cytoreduction, the median survival was 25 to 49 months. Major morbidity and mortality ranged from 15.1% to 47.2% and 0% to 4.5%, respectively. CONCLUSION CRS and HIPEC for the treatment of CRPM is safe and current evidence suggests it improves both median and disease-free survival. However, the efficacy of intraperitoneal chemotherapy, in particular oxaliplatin, has recently come under scrutiny. Accordingly, higher quality evidence is urgently required to contribute to multidisciplinary and international consensus on CRPM treatment strategies.

Abstract
BACKGROUND While parenchymal hepatic metastases were previously considered a contraindication to cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC), liver resection (LR) is increasingly performed with CRS/HIPEC. METHODS Patients from the US HIPEC Collaborative (2000-2017) with invasive appendiceal or colorectal adenocarcinoma undergoing primary, curative intent CRS/HIPEC with CC0-1 resection were included. LR was defined as a formal parenchymal resection. Primary endpoints were postoperative complications and overall survival (OS). RESULTS A total of 658 patients were included. About 83 (15%) underwent LR of colorectal (58%) or invasive appendiceal (42%) metastases. LR patients had more complications (81% vs. 60%; p = .001), greater number of complications (2.3 vs. 1.5; p < .001) per patient and required more reoperations (22% vs. 11%; p = .007) and readmissions (39% vs. 25%; p = .014) than non-LR patients. LR patients had decreased OS (2-year OS 62% vs. 79%, p < .001), even when accounting for peritoneal carcinomatosis index and histology type. Preoperative factors associated with decreased OS on multivariable analysis in LR patients included age < 60 years (HR, 3.61; 95% CI, 1.10-11.81), colorectal histology (HR, 3.84; 95% CI, 1.69-12.65), and multiple liver tumors (HR, 3.45; 95% CI, 1.21-9.85) (all p < .05). When assigning one point for each factor, there was an incremental decrease in 2-year survival as the risk score increased from 0 to 3 (0: 100%; 1: 91%; 2: 58%; 3: 0%). CONCLUSIONS As CRS/HIPEC + LR has become more common, we created a simple risk score to stratify patients considered for CRS/HIPEC + LR. These data aid in striking the balance between an increased perioperative complication profile with the potential for improvement in OS.

Abstract
Pseudomyxoma Peritonei (PMP) is a rare peritoneal malignancy, most commonly originating from a perforated epithelial tumour of the appendix. Given its rarity, randomized controlled trials on treatment strategies are lacking, nor likely to be performed in the foreseeable future. However, many questions regarding the management of appendiceal tumours, especially when accompanied by PMP, remain unanswered. This consensus statement was initiated by members of the Peritoneal Surface Oncology Group International (PSOGI) Executive Committee as part of a global advisory role in the management of uncommon peritoneal malignancies. The manuscript concerns an overview and analysis of the literature on mucinous appendiceal tumours with, or without, PMP. Recommendations are provided based on three Delphi voting rounds with GRADE-based questions amongst a panel of 80 worldwide PMP experts.

Abstract
The liver is the most common anatomical site for hematogenous metastases from colorectal cancer. Therefore effective treatment of liver metastases is one of the most challenging elements in the management of colorectal cancer. However, there is rare available clinical consensus or guideline only focusing on colorectal liver metastases. After six rounds of discussion by 195 clinical experts of the Shanghai International Consensus Expert Group on Colorectal Liver Metastases (SINCE) from 29 countries or regions, the Shanghai Consensus has been finally completed, based on current research and expert experience. The consensus emphasized the principle of multidisciplinary team, provided detailed diagnosis approaches, and guided precise local and systemic treatments. This Shanghai Consensus might be of great significance to standardized diagnosis and treatment of colorectal liver metastases all over the world.

Abstract
Colorectal cancer (CRC) is stated as the third most frequent cancer in people around the world. In patients, its recurrence occurs most commonly in the peritoneum, accounting for 25% to 35% of all recurrences, making it the second most common site for CRC. Although new and more effective chemotherapeutic agents and combinations were developed, the results of systemic chemotherapy showed only a limited impact on survival, which is disappointing. It is known that cytoreductive surgery (CRS) in combination with hyperthermic intraperitoneal chemotherapy (HIPEC) lead to survival improvement in comparison to the sole treatment consisting in intravenous chemotherapy. This combined procedure showed encouraging results in terms of overall survival, lower complication rates and better patient outcomes in many reported findings. The objective of this article was to review published data for evaluating the outcome of CRS and HIPEC versus standard of care.

Abstract
Peritoneal carcinomatosis (PC) was previously considered an incurable disease with a poor survival outcome. As our understanding of its biology evolved, the paradigm of the management of PC from colorectal cancer (CRC) has changed, including the combination of macroscopic disease control, cytoreductive surgery (CRS), maximal regional chemotherapy to treat residual microscopic disease, and hyperthermic intraperitoneal chemotherapy (HIPEC). As with many surgical innovations, CRS with HIPEC has evolved faster than data to support it, leaving many skeptics and critics. This review highlights the recent evidence of current practice and outcome of CRS with HIPEC. Furthermore, it also summarizes the ongoing clinical trials and potential future progress of this treatment modality.

Abstract
The peritoneum is a common site of dissemination for colorrectal cancer, with a poorer prognosis than other sites of metastases. In the last two decades, it has been considered as a locoregional disease progression and treated as such with curative intention treatments. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is the actual reference treatment for these patients as better survival results have been reached as compared to systemic chemotherapy alone, but its therapeutic efficacy is still under debate. Actual guidelines recommend that the management of colorectal cancer with peritoneal metastases should be led by a multidisciplinary team carried out in experienced centers and consider CRS + HIPEC for selected patients. Accumulative evidence in the last three years suggests that this is a curative treatment that may improve patients disease-free survival, decrease the risk of recurrence, and does not increase the risk of treatment-related mortality. In this review we aim to gather the latest results from referral centers and opinions from experts about the effectiveness and feasibility of CRS + HIPEC for treating peritoneal disease from colorectal malignancies.

Abstract
AIM OF THE STUDY Cytoreductive surgery including liver resection and hyperthermic intraperitoneal chemotherapy provide survival benefit to selected patients but is associated with relevant morbidity and mortality rates. We aimed to report morbidity and mortality rates and parameters linked to increased morbidity. PATIENTS AND METHODS Retrospective analysis of 37 patients who underwent liver resection and cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy between 2006 and 2016. From a prospectively collected database the morbidity and mortality rates and survival data were analyzed. RESULTS The mortality rate was 0% and grade III-IV morbidity was 42%. Re-operation rate was 27%. Patients with complications tended to have a higher peritoneal cancer index (16 vs. 13; P=0.23). The performance of rectal resections was statistically significantly associated with morbidity (P=0.02). Neither performance of other type of resections nor the hyperthermic intraperitoneal chemotherapy compound nor the completeness of cytoreduction score was associated with elevated morbidity. No complications related to liver resections were observed. Furthermore, origin of peritoneal metastases did not impact on occurrence of complications. Median overall survival for colorectal primaries was 22 months (range, 9-60 months) and 30 months (range, 12-58 months) for ovarian cancer. CONCLUSION Simultaneous resection of hepatic and peritoneal metastases seems to provide a survival benefit for selected patients and is associated with acceptable morbidity and mortality rates. Knowledge of patients and operative factors linked to morbidity will help to provide a strict selection process and a safer surgical procedure.

Abstract
BACKGROUND Management of patients with resectable hepatic metastases (HMs) and colorectal peritoneal carcinomatosis (CRPC) is not currently standardised. OBJECTIVE The aims of this study were to evaluate the safety of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) and hepatic surgery for patients with CRPC with synchronous hepatic metastases (HM), and its impact on survival rates. METHODS A retrospective analysis was performed, including patients undergoing CRS/HIPEC for CRPC from 2007 to September 2016 in two groups, with (HM+) and without (HM-) synchronous hepatic metastases. Patients with extra-abdominal metastases were excluded. The hepatic strategy was described. Morbimortality and survival were compared between the two groups. RESULTS One hundred nine patients underwent CRS/HIPEC for CRPC with or without hepatic surgery with curative intent: 33 patients with (HM+) and 76 patients without (HM-) synchronous HM. The median follow-up was 30 months. All patients with HM (HM+) received neoadjuvant chemotherapy vs. 88.1% in the HM- group (p = 0.04) associated with monoclonal antibody in 66.6% of cases in the HM+ group vs. 57% in the HM- group (p = 0.01). In the HM+ group, two steps were implemented to treat peritoneal and hepatic metastases in 15 patients (45%). In this group, planned hepatic resection in two procedures was performed for eight patients, all presenting bilobar HM. Postoperative morbidity did not differ between the two groups. No deaths occurred. Median overall survival (OS) and recurrence-free survival (RFS) were 31 and 65 months (p = 0.188), versus 21 and 24 months (p = 0.119), respectively, in the HM+ versus HM- groups. In multivariate analysis, the peritoneal cancer index (PCI) was the only significant prognostic factor whereas synchronous HM was not a significant prognostic factor. CONCLUSION Curative surgical treatment for CRPC with synchronous HM seems to be feasible and safe, and could facilitate long survival rates, compared to patients without HM. The hepatic strategy is not standardised. However, a "two-step" surgical strategy could be proposed in order to reduce postoperative morbidity rates.

Abstract
Peritoneal metastases may occur from a majority of cancers that occur within the abdomen or pelvis. When cancer spread to the peritoneal surfaces is documented, a decision regarding palliation versus an aggressive approach using cytoreductive surgery (CRS) and hyperthermic perioperative intraperitoneal chemotherapy (HIPEC) must be made. This decision is dependent on a well-defined group of prognostic indicators. In addition to treatment, prevention of peritoneal metastases may be an option. The clinical and pathologic features of a primary cancer can be used to select perioperative treatments that may prevent cancer cells within the abdomen and pelvis from progressing to established peritoneal metastases. In some clinical situations with appendiceal and colorectal cancers, the clinical or histopathologic features may indicate that second-look surgery plus perioperative chemotherapy should occur. Peritoneal metastases should always be considered by the multidisciplinary team for treatment or prevention.

Abstract
Background: Cytoreductive surgery (CRS), followed by hyperthermic intraperitoneal chemotherapy (HIPEC), combines radical surgery with abdominal heated chemotherapy, constituting a multimodal treatment approach. Since clear standards for HIPEC conduct in colorectal carcinoma (CRC) are lacking, we aimed to provide a comprehensive structured survey. Data sources and study eligibility criteria: A systematic literature search was performed in PubMed, with keywords “HIPEC” and “colorectal cancer”, according to established guidelines. Articles were systematically screened, selecting 87 publications complemented by 48 publications identified through extended search for subsequent synthesis and evaluation, extracting inter alia details on used drugs, dosage, temperature, exposure times, and carrier solutions. Results: Compiled publications contained 171 reports on HIPEC conduct foremost with mitomycin C and oxaliplatin, but also other drugs and drug combinations, comprising at least 60 different procedures. We hence provide an overview of interconnections between HIPEC protocols, used drugs and carrier solutions as well as their volumes. In addition, HIPEC temperatures and dosing benchmarks, as well as an estimate of in vivo resulting drug concentrations are demonstrated. Conclusions and implications: Owing to recent developments, HIPEC conduct and practices need to be reassessed. Unfortunately, imprecise and lacking reporting is frequent, which is why minimal information requirements should be established for HIPEC and the introduction of final drug concentrations for comparability reasons seems sensible.

Abstract
BACKGROUND Survival improvements have been reported in selected patients affected by colorectal peritoneal metastases who were undergoing cytoreductive surgery with intraperitoneal hyperthermic chemotherapy. Treatment of peritoneal metastases associated with extraperitoneal disease is still controversial. OBJECTIVE We assessed the prognostic impact of a history of extraperitoneal disease that was curatively treated either at the same time as or before the onset of peritoneal metastases. DESIGN We reviewed 2 prospective databases. Peritoneal involvement was scored by Peritoneal Cancer Index. SETTINGS Our study was conducted in 2 high-volume peritoneal malignancy management institutions. PATIENTS A total of 148 patients with peritoneal metastases were included. In 27 patients, extraperitoneal disease involving the liver (n = 23), lung (n = 1), both lung and liver (n = 2), or inguinal lymph nodes and liver (n = 1) was curatively treated either simultaneously with peritoneal metastases (n = 22) or before their onset (n = 5). INTERVENTIONS All of the macroscopic tumors were removed by means of peritonectomy procedures and visceral resections. Microscopic residual disease was treated by mitomycin C/cisplatin-based hyperthermic intraperitoneal chemotherapy. MAIN OUTCOME MEASURES Overall survival was the primary outcome measure. RESULTS After a median follow-up of 34.6 months (95% CI, 22.6-65.7 mo), 5-year survival of patients treated for both peritoneal and extraperitoneal disease versus peritoneal metastases alone was 16.5% versus 52.0% (p = 0.019). After multivariate analysis, reduced survival correlated with extraperitoneal disease (p = 0.001), Peritoneal Cancer Index >19 (p = 0.004), and peritoneal residual disease >2.5 mm (p = 0.018). Three prognostic groups were defined, and median survival was not reached for group 1 (Peritoneal Cancer Index ≤19 and no extraperitoneal disease), reached in 27.0 months for group 2 (Peritoneal Cancer Index ≤9 and extraperitoneal disease), and reached in 11.6 months for group 3 (Peritoneal Cancer Index >19 and no extraperitoneal disease or Peritoneal Cancer Index >9 and extraperitoneal disease). LIMITATIONS The main study limitation is its observational nature. CONCLUSIONS A history of extraperitoneal disease is associated with poorer prognosis. However, survival benefit may be obtained in selected patients with limited peritoneal involvement. See Video Abstract at http://links.lww.com/DCR/A655.

Abstract
PURPOSE OF REVIEW Peritoneal metastases may occur from a majority of cancers that occur within the abdomen or pelvis. When cancer spread to the peritoneal surfaces is documented, a decision regarding palliation vs. an aggressive approach using cytoreductive surgery (CRS) and perioperative intraperitoneal chemotherapy must be made. The perioperative chemotherapy may be hyperthermic intraperitoneal chemotherapy (HIPEC) administered in the operating room or early postoperative intraperitoneal chemotherapy (EPIC) administered in the first 4 or 5 postoperative days. RECENT FINDINGS This decision is dependent on a well-defined group of prognostic indicators. In addition to treatment, the clinical and pathologic features of a primary cancer can be used to select perioperative treatments that may prevent cancer cells within the abdomen and pelvis from progressing to established peritoneal metastases. In some clinical situations with appendiceal and colorectal cancers, the clinical or histopathologic features may indicate that second-look surgery plus perioperative chemotherapy should occur. Peritoneal metastases should always be considered for treatment or prevention.

Abstract
Cytoreduction and heated intraperitoneal chemotherapy (CS/HIPEC) is increasingly utilized as a treatment strategy for patients with peritoneal metastases from various primary tumor sites. For this heterogenous procedure, related to patient characteristics, patient selection, and the extent of surgical completeness of cytoreduction, high level evidence (ex: multiple randomized controlled trials) is not available to support efficacy. This review of the available literature supporting application of the procedure, focusing on colorectal cancer, provides a summary of current evidence for patient selection and treatment algorithms based on patient presentation.

Influence of simultaneous liver and peritoneal resection on postoperative morbi-mortality and survival in patients with colon cancer treated with surgical cytoreduction and intraperitoneal hyperthermic chemotherapy. Cir Esp 2017; 95:214-221. [PMID: 28400138 DOI: 10.1016/j.ciresp.2017.03.003] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2016] [Revised: 03/07/2017] [Accepted: 03/09/2017] [Indexed: 12/13/2022]
Abstract
INTRODUCTION Cytoreductive surgery plus intraperitoneal hyperthermic chemotherapy (HIPEC) has recently been established as the treatment of choice for selected patients with peritoneal carcinomatosis of colonic origin. Until recently, the simultaneous presence of peritoneal and hepatic dissemination has been considered a contraindication for surgery. The aim of this paper is to analyze the morbidity, mortality and survival of patients with simultaneous peritoneal and hepatic resection with HIPEC for peritoneal carcinomatosis secondary to colon cancer. METHODS Between January 2010 and January 2015, 61 patients were operated on, 16 had simultaneous peritoneal and hepatic dissemination (group RH+), and 45 presented only peritoneal dissemination (group RH-). RESULTS There were no differences between the groups in terms of demographic data, length of surgery and extension of peritoneal disease. Postoperative grade III-V complications were significantly higher in the RH+ group (56.3 vs. 26.6%; P=.032). For the whole group, mortality rate was 3.2% (two patients in group RH-, and none in group RH+). Patients with liver resection had a longer postoperative stay (14.4 vs. 23.1 days) (P=.027). Median overall survival was 33 months for RH-, and 36 for RH+ group. Median disease-free survival was 16 months for RH-, and 24 months for RH+ group. CONCLUSIONS Simultaneous peritoneal cytoreduction and hepatic resection resulted in a significantly higher Clavien grade III-V morbidity and a longer hospital stay, although the results are similar to other major abdominal interventions. The application of multimodal oncological and surgical treatment may obtain similar long-term survival results in both groups.

Recommendations and consensus on the treatment of peritoneal metastases of colorectal origin: a systematic review of national and international guidelines. Colorectal Dis 2017; 19:224-236. [PMID: 28008728 DOI: 10.1111/codi.13593] [Citation(s) in RCA: 74] [Impact Index Per Article: 10.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2016] [Accepted: 11/01/2016] [Indexed: 12/13/2022]
Abstract
AIM This systematic review aimed to provide an overview of (inter)national guidelines on the treatment of peritoneal metastases of colorectal cancer origin (PMCRC) and to determine the degree of consensus and available evidence with identification of topics for future research. METHOD A systematic search of MEDLINE, Embase, PubMed as well as Tripdatabase, National Guideline Clearinghouse, BMJ Best Practice and Guidelines International Network was performed to identify (inter)national guidelines and consensus statements from oncological or surgical societies on PMCRC. The quality of guidelines was assessed using the AGREE-II score. Topics followed by recommendations were extracted from the guidelines. The recommendations, highest level of supporting evidence and the degree of consensus were determined for each topic. RESULTS Twenty-one guidelines were included, in most (15) of which cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) was recommended in selected patients based on level 1b evidence. Substantial consensus was also reached on the benefit of multidisciplinary team discussion and the achievability of a (near) complete cytoreduction (CC0-1) without supporting evidence. Both evidence and consensus were lacking regarding other aspects including preoperative positron emission tomography/CT, second look surgery in high risk patients, the optimal patient selection for CRS/HIPEC, procedural aspects of HIPEC and (perioperative) systemic therapy. CONCLUSION In currently available guidelines, evidence and consensus on the treatment strategy for PMCRC are lacking. Updates of guidelines are ongoing and future (randomized) clinical trials should contribute to multidisciplinary and international consensus on treatment strategies for PMCRC.

Abstract
Peritoneum is one of the common sites of metastasis in advanced stage colorectal cancer patients. Colorectal cancer patients with peritoneal metastases (PM) are traditionally believed to have poor prognosis, which indicates it is of no value to adopt surgical treatment. With the advancement of surgical techniques, hyperthermic intraperitoneal chemotherapy (HIPEC), and multidisciplinary treatment in recent years, the cognition and treatment strategies of colorectal peritoneal metastases (CPM) have changed dramatically. In terms of prognosis, CPM under the palliative systemic treatment shows an inferior outcome compared with nonperitoneal metastasis. Nevertheless, some CPM patients amenable to the complete peritoneal cytoreductive surgery (CRS) combined with HIPEC may achieve long-term survival. The prognostic factors of CPM comprise peritoneal carcinomatosis index (PCI), completeness of cytoreduction score (CC score), the presence of extraperitoneal metastasis (liver, etc.), Peritoneal Surface Disease Severity Score (PSDSS), Japanese peritoneal staging, and so forth. Taken together, literature data suggest that a multimodality approach combining complete peritoneal CRS plus HIPEC, systemic chemotherapy, and targeted therapy may be the best treatment option for PM from colorectal cancer.

Abstract
OBJECTIVES This study describes the outcomes of patients with colorectal peritoneal carcinomatosis (PC) with or without liver metastases (LMs) after curative surgery combined with hyperthermic intraperitoneal chemotherapy, in order to assess prognostic factors. BACKGROUND Cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) increases overall survival (OS) in patients with PC. The optimal treatment both for PC and for LMs within one surgical operation remains controversial. METHODS Patients with PC who underwent CRS followed by HIPEC were evaluated from a prospective database. Overall survival and disease free survival (DFS) rates in patients with PC and with or without LMs were compared. Univariate and multivariate analyses were performed to evaluate predictive variables for survival. RESULTS From 1999 to 2011, 22 patients with PC and synchronous LMs (PCLM group), were compared to 36 patients with PC alone (PC group). No significant difference was found between the two groups. The median OS were 36 months [range, 20-113] for the PCLM group and 25 months [14-82] for the PC group (p > 0.05) with 5-year OS rates of 38% and 40% respectively (p > 0.05). The median DFS were 9 months [9-20] and 11.8 months [6.5-23] respectively (p = 0.04). The grade III-IV morbidity and cytoreduction score (CCS) >0 (p < 0.05) were identified as independent factors for poor OS. Resections of LMs and CCS >0 impair significantly DFS. CONCLUSIONS Synchronous complete CRS of PC and LMs from a colorectal origin plus HIPEC is a feasible therapeutic option. The improvement in OS is similar to that provided for patients with PC alone.

Abstract
BACKGROUND Chemotherapeutic advances have enabled successful cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) expansion in treating metastatic colorectal cancer. OBJECTIVES The aims of this study were to evaluate the safety of combining liver surgery (LS) with HIPEC and CRS (which remains controversial) and its impact on overall survival (OS) rates. METHODS From 2007 to 2015, a total of 77 patients underwent CRS/HIPEC for peritoneal carcinomatosis (PC) of colorectal cancer. Twenty-five of these patients underwent concomitant LS for suspicion of liver metastases (LM; group 2), and were compared with patients who underwent CRS/HIPEC only (group 1). Demographic and clinical data were reviewed retrospectively. RESULTS Among the group 2 patients, two underwent major hepatectomies, six underwent multiple wedge resections, 16 underwent single wedge resections (one with radiofrequency ablation), and one underwent radiofrequency ablation alone. For groups 1 and 2, median peritoneal cancer index was 6 and 10 (range 0-26; p = 0.08), complication rates were 15.4 and 32.0 % (Dindo-Clavien ≥3; p = 0.15), and median follow-up was 34.2 and 25.5 months (range 0-75 and 3-97), respectively. One group 2 patient died of septic shock after 66 days. Pathology confirmed LM in 21 patients in group 2 (four with benign hepatic lesions were excluded from long-term outcome analysis). Two-year OS rates were 89.5 and 70.2 % (p = 0.04), and 2-year recurrence-free survival rates were 38.3 and 13.4 % (p = 0.01) in groups 1 and 2, respectively. CONCLUSIONS Simultaneous surgery for colorectal LM and PC is both feasible and safe, with low postoperative morbidity. Further longer-term studies would help determine its impact on patient survival.

Abstract
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.

Abstract
PURPOSE Metastasectomy for intrahepatic metastases (IHM) from colorectal cancer (CRC) provides excellent 5-year overall survival (OS). Presence of extrahepatic metastases (EHM) has been a historic contraindication to surgery. Due to improved safety of hepatectomy, there is growing interest in multisite metastasectomy for IHM and EHM. The objective of this study was to evaluate the results of metastasectomy for patients with IHM and EHM from CRC. METHODS A phase II study of metastasectomy for both IHM and EHM from CRC. Eligible patients with any number of IHM and up to three EHM foci, resectable with RO intent, were offered metastasectomy. Clinical, survival, and quality of life (QoL) data were analyzed using standard statistical methods. RESULTS Twenty-six patients were enrolled with a median age of 58 (range 32-84) years; 14/26 (54 %) presented with synchronous disease. The lung was the most common EHM site (13/26, 50 %). Protocol surgery was completed in 20/26 (77 %), including 12/26 (46 %) planned sequential resections. Major morbidity and perioperative mortality were 5/26 (19 %) and 1/26 (4 %), respectively. The QoL decline appeared to be transient. All QoL domains returned to baseline by 1-year posttreatment. The median recurrence-free survival (RFS) was 5 months by intent-to-treat analysis. The median OS from the time of CRC diagnosis and metastasectomy were 50 and 38 months (3-year OS 80 and 53 %), respectively. CONCLUSIONS Complete metastasectomy of multisite CRC is safe, but disease recurs in the majority of patients. Data suggest that aggressive multisite metastasectomy may provide OS benefit for selected patients.

Abstract
BACKGROUND Colorectal cancer (CRC) accounts for 9.7% of all cancers with 1.4 million new cases diagnosed each year. 19-31% of CRC patients develop colorectal liver metastases (CRLM), and 23-38% develop extra-hepatic disease (EHD). The aim of this systematic review was to determine overall survival (OS) in patients resected for CRLM and known EHD. METHODS A systematic review was undertaken to identify studies reporting OS after resection for CRLM in the presence of EHD. Proportional meta-analyses and relative risk of death before five years were assessed between patient groups. RESULTS A total of 15,144 patients with CRLM (2308 with EHD) from 52 studies were included. Three and 5-year OS were 58% and 26% for lung, 37% and 17% for peritoneum, and 35% and 15% for lymph nodes, respectively. The combined relative risk of death by five years was 1.49 (95% CI = 1.34-1.66) for lung, 1.59 (95% CI = 1.16-2.17) for peritoneal and 1.70 (95% CI = 1.57-1.84) for lymph node EHD, in favour of resection in the absence of EHD. CONCLUSION This review supports attempts at R0 resection in selected patients and rejects the notion that EHD is an absolute contraindication to resection.

Abstract
BACKGROUND We examined outcomes of patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) combined with liver resection. METHODS All patients undergoing CRS/HIPEC between 2007 and 2014 were retrospectively reviewed: patients who underwent synchronous liver resection (group 1) were compared with those who did not (group 2) in terms of perioperative and long-term results. RESULTS Group 1 included 103 patients with colorectal cancer (CRC, n = 28), appendiceal cancer (n = 34), and other malignancies. Compared with group 2 (n = 166), group 1 had higher number of organs resected, increased intraoperative blood loss, and longer hospital stay (all P ≤ 0.004) but similar major morbidity (24.3% vs. 18.1%, P = 0.22) and perioperative mortality rates. Two patients from group 1 developed liver resection-related complications. A comparison between patients who underwent parenchymal liver resection (n = 42) and matched pairs from group 2 with similar extent of cytoreduction did not yield significant differences in morbidity/mortality. CRC patients from group 1 had poorer median overall survival (45.1 vs. 73.5 months from stage IV diagnosis, P = 0.009). CONCLUSIONS Liver involvement denotes high peritoneal carcinomatosis burden, which often requires resection of multiple organs in order to achieve optimal cytoreduction. However, liver resection-related morbidity is low and overall morbidity/mortality rates are comparable to other extensive CRS/HIPEC procedures. J. Surg.

Abstract
Peritoneal metastases (PM) from colorectal cancer (CRC) were traditionally associated with bad prognosis. Only recently, cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has resulted in survival improvements. A systematic literature search between January 2010 and June 2015 was performed. Studies were selected and appraised according to predetermined criteria. Nineteen cohort studies, and thirteen comparative studies of CRS/HIPEC were included. The weighted median overall survival was 31.6 months (range 16-51). Major morbidity was 17.6-52.4% (weighted average 32.6%). Mortality was 0-8.1% (weighted average 2.9%). Additional relevant topics, such as CRC-PM prevalence, results by systemic therapies, preoperative work-up, and technical aspects were summarized through a narrative review. The recent literature suggests that CRS/HIPEC is gaining acceptance as standard of care for selected CRC-PM patients. Refinement of selection criteria, and rationalization of comprehensive systemic and local-regional management is ongoing. Prevention and early treatment of PM are new and promising options.

Abstract
Surgical resection of colorectal liver metastases (CRLM) has a well-documented improvement in survival. To benefit from this intervention, proper selection of patients who would be adequate surgical candidates becomes vital. A combination of imaging techniques may be utilized in the detection of the lesions. The criteria for resection are continuously evolving; currently, the requirements that need be met to undergo resection of CRLM are: the anticipation of attaining a negative margin (R0 resection), whilst maintaining an adequate functioning future liver remnant. The timing of hepatectomy in regards to resection of the primary remains controversial; before, after, or simultaneously. This depends mainly on the tumor burden and symptoms from the primary tumor. The role of chemotherapy differs according to the resectability of the liver lesion(s); no evidence of improved survival was shown in patients with resectable disease who received preoperative chemotherapy. Presence of extrahepatic disease in itself is no longer considered a reason to preclude patients from resection of their CRLM, providing limited extra-hepatic disease, although this currently is an area of active investigations. In conclusion, we review the indications, the adequate selection of patients and perioperative factors to be considered for resection of colorectal liver metastasis.

Cytoreductive surgery (SRC) and hyperthermic intraperitoneal chemotherapy (HIPEC) for treatment of peritoneal carcinomatosis: Our initial experience and technical details. Turk J Surg 2015; 31:138-47. [PMID: 26504417 PMCID: PMC4605109 DOI: 10.5152/ucd.2015.2990] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2014] [Accepted: 01/22/2015] [Indexed: 12/22/2022]
Abstract
OBJECTIVE The aim of this study is to present our initial experience in peritoneal carcinomatosis treatment and the technical details of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in the light of current literature. MATERIAL AND METHODS Data of 27 consecutive patients who were treated with CRS and HIPEC for peritoneal carcinomatosis in Medical Park Samsun Hospital, between November 2012 and September 2014 were retrospectively reviewed. Treatment indication and management were evaluated at the multidisciplinary oncology council. All patients underwent CRS and HIPEC with the aim of complete cytoreduction. Patients with unresectable disease and/or palliative surgery were excluded from analysis. Perioperative complications were classified according to Clavien-Dindo classification, and HIPEC-related side effects were identified using National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) criteria. Demographic, clinical and histopathological data of the patients were analyzed. RESULTS The mean age was 54 (32-72). Nineteen patients were female. The origin of peritoneal carcinomatosis was colorectal cancer in 12 patients, ovarian cancer in 12 patients, gastric cancer in 2 patients and pseudomyxoma peritonei in 1 patient. The mean Peritoneal Carcinomatosis Index was 12 (3-32), with a mean operative time of 420 (300-660) minutes. Perioperative morbidity, HIPEC-related toxicity and perioperative mortality were observed in eight (30%), one (3.7%) and four patients (14.8%), respectively. During a mean follow up of 13 (1-22) months, overall and disease-free survival rates were 95.8% and 82.6%, respectively. Two patients with colorectal cancer (after 9 and 12 months) and one patient with ovarian cancer (after 11 months) had intra-abdominal recurrence. One patient with ovarian cancer had liver metastases 13 months after surgery, and underwent resection of segments 6-7. The remaining patients are being followed-up without any recurrence. CONCLUSION Cytoreductive surgery and HIPEC have favorable results in the treatment of patients with peritoneal carcinomatosis. Compatible with the literature, surgical outcomes of the presented series are encouraging for this treatment modality that have been recently popularized in our country. Careful perioperative evaluation, proper patient selection and multidisciplinary approach are essential for success in curative treatment of peritoneal carcinomatosis.

Abstract
Introduction Treatment for advanced stage colorectal cancer with synchronous peritoneal carcinomatosis (PC) and hepatic metastasis (HM) has progressed significantly over the past 10 years. Case report We present the case of a 39-year-old female patient with stage IV colorectal cancer with bilateral HM, pulmonary oligometastatic disease, and diffuse PC who underwent hyperthermic intraperitoneal chemotherapy (HIPEC) and complete cytoreductive surgery (CRS) for her intra-abdominal disease. The patient had an uneventful immediate post-operative recovery, and subsequently tolerated multiple cycles of adjuvant chemotherapy and percutaneous radiofrequency ablation of pulmonary lesions. At her 22-month follow-up assessment, the patient remains alive with disease. Conclusion Current recommendations for surgical management of synchronous colorectal cancer PC and HM indicate that patients with less than three HMs, a low peritoneal cancer index (PCI), and good functional status will benefit most from CRS and HIPEC. Our patient had an elevated PCI of 12 as measured by computed tomography imaging, and five HMs (all less than 3 cm in size); however, given that her life expectancy on systemic chemotherapy was estimated to be approximately 12 months, we have observed carefully selected patients to benefit from an aggressive multi-modality approach. This case report demonstrates an all too common scenario for surgeons managing patients with advanced CRC, and highlights the importance of patient selection for surgical management as part of multidisciplinary cancer care in this patient population.

Abstract
To meet the needs of patients, Canadian surgical and medical oncology leaders in the treatment of peritoneal surface malignancies (psms), together with patient representatives, formed the Canadian HIPEC Collaborative Group (chicg). The group is dedicated to standardizing and improving the treatment of psm in Canada so that access to treatment and, ultimately, the prognosis of Canadian patients with psm are improved. Patients with resectable psm arising from colorectal or appendiceal neoplasms should be reviewed by a multidisciplinary team including surgeons and medical oncologists with experience in treating patients with psm. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy should be offered to appropriately selected patients and performed at experienced centres. The aim of this publication is to present guidelines that we recommend be applied across the country for the treatment of psm.

Abstract
The peritoneal stromal tissue which provides a rich source of growth factors and chemokines is a favorable environment for tumor proliferation. The pathophysiological mechanism of peritoneal carcinomatosis is an individual sequence consisting of genetic and environmental factors and remains controversial. The natural history of the disease reveals a poor median prognosis of approximately 6 mo; however aggressive surgery and multimodal treatment options can improve oncologic outcomes. Considering peritoneal carcinomatosis as though it is a locoregional disease but not a metastatic process, cytoreductive surgery and and intraperitoneal chemotherapy has been a curative option during recent years. Cytoreductive surgery implies a series of visceral resections and peritonectomy procedures. Although the aim of cytoreductive surgery is to eliminate all macroscopic disease, viable tumor cells may remain in the peritoneal cavity. At that point, intraperitoneal chemotherapy can extend the macroscopic disease elimination to microscopic disease elimination. The successful treatment of peritoneal carcinomatosis requires a comprehensive management plan including proper patient selection, complete resection of all visible disease, perioperative intraperitoneal chemotherapy and postoperative systemic chemotherapy. Surgical and oncologic outcomes are strictly associated with extent of the tumor, completeness of cytoreduction and patient-related factors as well as multidisciplinary management and experience of the surgical team. In this review, pathophysiology and current management of peritoneal carcinomatosis originating from gastrointestinal tumors are discussed according to the latest literature.

Abstract
PURPOSE Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are a novel curative treatment option for selected patients with peritoneal carcinomatosis (PC). We aimed to report the mortality rate and the most frequent grade III-IV adverse events and to identify associated prognostic markers. We report oncological outcomes and major prognostic factors influencing overall survival (OS) and disease-free survival. METHODS A total of 401 CRS plus HIPEC procedures were performed on 356 patients. Mortality, grade III-IV adverse events, OS, disease-free survival, and prognostic factors were studied. RESULTS Based on Common Terminology Criteria for Adverse Events (CTCAE of the National Cancer Institute 2006), mortality rate was 1 % and overall rate of morbidity grade III-IV was 12.5 %. In multivariate analysis, only the number of digestive anastomoses (>1) significantly correlated with adverse events with an odds ratio of 2.8 (p = 0.032). OS was related to histological type of PC, with a median survival reaching 47.6 months for PC of ovarian cancer origin, 45.8 months for that of colorectal origin, 64.2 months for peritoneal mesothelioma, and 8.1 months for PC of gastric cancer origin. Over half the patients with pseudomyxoma are still alive. Major prognostic factors influencing survival were histological type, World Health Organization performance status (WHO PS) (hazard ratio (HR) = 3.56), operating time (HR = 0.45), previous chemotherapy (HR = 2.04), number of peritonectomies (HR = 2.03), and completeness of cytoreduction score (HR = 3.12). Disease-free survival across all groups was 16.8 months. CONCLUSION The low mortality rate and 12.5 % grade III-IV morbidity of CRS and HIPEC are acceptable when weighed against overall oncologic survival. This multimodal treatment appears feasible for selected patients and trained centers.

Abstract
Colorectal peritoneal carcinomatosis was considered a terminal condition with a merely palliative treatment that included only supportive care, palliative surgery and the best systemic chemotherapy. Since the birth of a new approach, cytoreductive surgery with peritonectomy procedures together with hyperthermic intraperitoneal chemotherapy and/or early postoperative intraperitoneal chemotherapy to treat peritoneal carcinomatosis, many research groups contributed with promising results using this procedure being up to date this strategy the only one that has shown curative benefits on colorectal peritoneal carcinomatosis achieving reported overall survival rates up to 64 mo and five-year survival rates up to 51%. The aim of this paper is to expose an updated overview of the therapeutic possibilities of these procedures in colorectal peritoneal metastases in the same way that our Unit of Oncologic Surgery has performed since 1997 with more than four hundred procedures.

Abstract
BACKGROUND Today, we do not have a universally accepted evidence on how to treat peritoneal carcinomatosis (PC) from colorectal cancer (CRC) in international guidelines. METHODS The present study is a review of the literature investigating current strategies to treat CRC PC. RESULTS Despite the progresses of systemic chemotherapy, the presence of PC among patients with metastatic CRC reduces the overall survival to 30 %, and only 4 % of patients with PC from CRC treated are alive for 5 years. Many trials evaluate the combined treatment of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for CRC PC, suggesting a survival benefit in highly selected patients. Only one trial is randomized and presents some biases. The two main prognostic factors are Peritoneal Cancer Index (PCI) and completeness of cytoreduction score (CC score). There is no universal agreement on how to approach the synchronous presence of PC and liver metastasis with a curative intent during the same procedure. A growing interest among the scientific community has arisen about systematic second-look surgery and HIPEC treatment in high-risk patients. CONCLUSION Current evidences suggest that CRS and HIPEC might be beneficial in highly selected patients affected with PC from CRC. Anyway, today, there is a shortage of well-designed phase 3 trials.

Abstract
Colorectal carcinoma (CRC) is the third most common cancer, and approximately 35%-55% of patients with CRC will develop hepatic metastases during the course of their disease. Surgical resection represents the only chance of long-term survival. The goal of surgery should be to resect all metastases with negative histological margins while preserving sufficient functional hepatic parenchyma. Although resection remains the only chance of long-term survival, management strategies should be tailored for each case. For patients with extensive metastatic disease who would otherwise be unresectable, the combination of advances in medical therapy, such as systemic chemotherapy (CTX), and the improvement in surgical techniques for metastatic disease, have enhanced prognosis with prolongation of the median survival rate and cure. The use of portal vein embolization and preoperative CTX may also increase the number of patients suitable for surgical treatment. Despite current treatment options, many patients still experience a recurrence after hepatic resection. More active systemic CTX agents are being used increasingly as adjuvant therapy either before or after surgery. Local tumor ablative therapies, such as microwave coagulation therapy and radiofrequency ablation therapy, should be considered as an adjunct to hepatic resection, in which resection cannot deal with all of the tumor lesions. Formulation of an individualized plan, which combines surgery with systemic CTX, is a necessary task of the multidisciplinary team. The aim of this paper is to discuss different approaches for patients that are treated due to CRC liver metastasis.

Abstract
BACKGROUND Concomitant treatment of colorectal peritoneal metastases (PM) and hepatic metastases (HM) remains controversial. This study compares the cytoreductive surgery (CRS) and intraperitoneal chemotherapy (IPC) treatment of colorectal peritoneal metastases (PM) with the CRS/IPC/hepatic resection treatment of colorectal PM and HM. METHODS All patients from a prospective PM registry at the Uppsala institution treated concomitantly for PM/HM with CRS/IPC/hepatic resections were included in a PM/HM-group, n=11. They were matched 1(:)2 with patients from the registry being treated only for PM with CRS/IPC, n=22. Overall survival (OS), disease-free survival (DFS), morbidity, mortality, and recurrences were compared. RESULTS The PM/HM-group had median OS of 15 months (95% CI: 6-46 months) and the PM-group had a median OS of 34 months (95% CI: 19-37 months), P=0.2. The DFS was 10 months (95% CI: 3-14 months)
and 24 months (95% CI: 10-32 months) respectively, P=0.1. Morbidity was 27% in both groups and one postoperative death in the PM/HM-group. Currently, 1/10 (10%) patients with an R1 resection are
disease-free in the PM/HM group while 9/20 (45%) are disease-free in the PM group (P=0.05). CONCLUSIONS Concomitant treatment of PM and HM with CRS/IPC/hepatic resections is feasible with no significant increase in morbidity compared to CRS/IPC. The risk of recurrences is higher in the PM/HM group with a tendency towards worse DFS.

Abstract
BACKGROUND Peritoneal carcinomatosis and liver metastases are common metastatic sites in patients who have colorectal cancer. Quite frequently, patients present with both synchronous liver and peritoneal metastases, which may result in a dilemma regarding the optimal treatment. OBJECTIVE In the absence of reliable data, the aim of the current study was to provide population-based data on such patients and to review the literature for possible treatment options. DESIGN This study is a retrospective analysis of a prospective database and a review. PATIENTS All patients diagnosed between 1995 and 2010 with synchronous peritoneal carcinomatosis and liver metastases were identified from the Eindhoven Cancer Registry. OUTCOME MEASURES Incidence and survival were analyzed. Next, the literature was reviewed for articles reporting on the results of treatment with curative intent. RESULTS In total, 27,632 patients were diagnosed with colorectal cancer, of whom 5638 patients (20%) presented with metastasized disease. Synchronous liver metastasis and peritoneal carcinomatosis were present in 440 patients, being 11% of patients with liver metastases, 34% of patients with peritoneal carcinomatosis, 8% of patients with metastasized disease, and 2% of all patients diagnosed with colorectal cancer. Median survival for patients with liver metastasis and peritoneal carcinomatosis was 5 months, in comparison with 95 months for patients with nonmetastasized disease. No improvement in survival was noted over time. None of the patients underwent treatment with curative intent during this period. LIMITATIONS No data on the extent of peritoneal carcinomatosis and liver metastases were available in the population-based study. This complicates comparison with treated patients from the literature review, which probably reflects a highly selected patient population. CONCLUSIONS Both liver metastasis and peritoneal carcinomatosis were present in 8% of patients presenting with metastasized colorectal cancer. Population-based survival was only 5 months, with none of the patients undergoing treatment with curative intent. Median survival rates of up to 36 months after treatment with curative intent as published in the literature may be regarded as promising for selected patients.

Abstract
OBJECTIVE This study aimed to assess the prognostic impact of liver metastases (LM) in patients with colorectal peritoneal carcinomatosis (PC) who underwent complete cytoreductive surgery and resection of LM, followed by intraperitoneal chemotherapy. BACKGROUND Synchronous surgical treatment of PC and LM with curative intent remains controversial. METHODS From a prospective database, all patients with PC and synchronous LM who had undergone cytoreductive surgery and LM resection followed by intraperitoneal chemotherapy were matched with patients with PC alone according to the following criteria: age, peritoneal cancer index (PCI), site and lymph node involvement (pN) of primary cancer, and postoperative chemotherapy. RESULTS From 1993 to 2009, 37 patients with PC and LM were matched with 61 patients with PC alone. After a mean follow-up of 36 months, 3-year overall survival (OS) and disease-free survival rates were significantly lower in patients with PC and LM, respectively, 40% and 66% (P = 0.04) and 6% and 27% (P = 0.001). A PCI of 12 or more [odds ratio (OR): 4.6], a pN+ status (OR: 3.3), no adjuvant chemotherapy (OR: 3.0), and presence of LM (OR: 2.0) were identified as independent factors for poor OS. Three groups were singled out: (1) patients with a low PCI (<12) and no LM (median OS: 76 months); (2) patients with a low PCI (<12) and 1 or 2 LM (median OS: 40 months); and (3) patients with a high PCI (≥12) or patients with 3 LMs or more (median OS: 27 months). CONCLUSIONS This case-control study seems to confirm that prolonged survival can be achieved in highly selected patients operated on for limited PC and fewer than 3 LM.

Abstract
Cytoreductive surgery (CRS) in combination with hyperthermic intraperitoneal chemotherapy (HIPEC) is an established treatment modality for patients with pseudomyxoma peritonei. The majority of patients with pseudomyxoma who have complete tumour removal and HIPEC are cured. Over the last decade CRS for peritoneal metastasis of colorectal origin has emerged as an effective treatment strategy in carefully selected patients. Although convincing evidence is limited, available data shows promising results. The key to a successful outcome is appropriate selection of patients. In patients with extensive peritoneal disease, where complete cytoreduction is not achieved, surgical treatment may not be beneficial and might impair quality of life. In this paper we discuss the challenges of selecting patients with colorectal peritoneal metastases who are likely to benefit from CRS with HIPEC.
