Abstract
Background This study aimed to identify the cumulative incidence and risk factors of metachronous peritoneal metastasis (M‐PM) from colorectal cancer in patients who had intended curative treatment. Methods Patients with colorectal cancer were identified using the Danish Colorectal Cancer Group database for 2006–2015. The Danish Pathology Registry and the Danish National Patient Registry were used to identify M‐PM to 2017. Risk factors were estimated by multivariable absolute risk regression, treating death and other cancers as competing risks. Overall risk and risk differences (RDs) were estimated at 1, 3 and 5 years. Results In 22 586 patients with colorectal cancer, the overall risk of M‐PM was reported to be 0·9 (95 per cent c.i. 0·8 to 1·0) per cent at 1 year, 1·9 (1·8 to 2·1) per cent at 3 years and 2·2 (2·0 to 2·4) per cent at 5 years. Advanced tumour category ((y)pT4 versus (y)pT1) increased the RD of both M‐PM (2·9 (95 per cent c.i. 2·1 to 3·7) at 1 year and 6·0 (4·9 to 7·2) at 3 years) and lymph node involvement ((y)pN2 versus (y)pN0) (2·5 (1·8 to 3·2) at year and 4·3 (3·2 to 5·3) at 3 years). No further increase in risk was observed at 5 years. In a subanalysis, tumour‐involved resection margin (R1 versus R0) was associated with M‐PM with a RD of 3·9 (1·6 to 6·2) at 1 year and 5·9 (2·6 to 9·3) at 3 years. Conclusion The overall risk of M‐PM in patients with colorectal cancer is low, but is increased in advanced T and N status. Follow‐up of at least 3 years after colorectal cancer surgery may be necessary, given the potential curative treatment of early diagnosed M‐PM.

Abstract
INTRODUCTION The addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreductive surgery (CRS) improves recurrence-free (RFS) and overall survival (OS) in patients with FIGO stage III ovarian cancer. We evaluated the effect of HIPEC on patient's health-related quality of life (HRQoL) in the OVHIPEC trial. MATERIALS AND METHODS OVHIPEC was a multicentre, open-label, randomized phase III trial for patients with stage III ovarian cancer. Patients were randomly assigned (1:1) to receive interval CRS with or without HIPEC with cisplatin. HRQoL was assessed using the EORTC QLQ-C30, and the ovarian (QLQ-OV28) and colorectal cancer (QLQ-CR38) modules. HRQoL questionnaires were administered at baseline, after surgery, after end of treatment, and every three months thereafter. HRQoL was a secondary endpoint, with the prespecified focus on the QLQ-C30 summary score and symptom scores on fatigue, neuropathy and gastro-intestinal symptoms. HRQoL was analysed using linear and non-linear mixed effect models. RESULTS In total, 245 patients were randomized. One-hundred-ninety-seven patients (80%) completed at least one questionnaire. No significant difference over time in the QLQ-C30 summary scores was observed between the study arms (p-values for linear and non-linear growth: p > 0.133). The pattern over time for fatigue, neuropathy and gastro-intestinal symptoms did not significantly differ between treatment arms. CONCLUSION The addition of HIPEC to interval CRS does not negatively impact HRQoL in patients with stage III ovarian cancer who are treated with interval CRS due to the extent of disease. These HRQoL results, together with the improvement in RFS and OS, support the viability of HIPEC as an important treatment option in this patient population. CLINICALTRIALS. GOV NUMBER NCT00426257.

Abstract
BACKGROUND Patients presenting with peritoneal metastases (PM) of colorectal cancer (CRC) can be curatively treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Angiogenesis is under control of multiple molecules of which HIF1a, SDF1, CXCR4, and VEGF are key players. We investigated these angiogenesis-related markers and their prognostic value in patients with PM arising from CRC treated with CRS and HIPEC. PATIENTS AND METHODS Clinicopathological data and tissue specimens were collected in 2 tertiary referral centers from 52 patients who underwent treatment for isolated PM of CRC. Whole tissue specimens were subsequently analyzed for protein expression of HIF1a, SDF1, CXCR4, and VEGF by immunohistochemistry. Microvessel density (MVD) was analyzed by CD31 immunohistochemistry. The relationship between overall survival (OS) and protein expression as well as other clinicopathological characteristics was analyzed. RESULTS Univariate analysis showed that high peritoneal cancer index (PCI), resection with residual disease and high expression of VEGF were negatively correlated with OS after treatment with CRS and HIPEC (P < 0.01, P < 0.01, and P = 0.02, respectively). However, no association was found between the other markers and OS (P > 0.05). Multivariate analysis showed an independent association between OS and PCI, resection outcome and VEGF expression (multivariate HR: 6.1, 7.8 and 3.8, respectively, P ≤ 0.05). CONCLUSIONS An independent association was found between high VEGF expression levels and worse OS after CRS and HIPEC. The addition of VEGF expression to the routine clinicopathological workup could help to identify patients at risk for early treatment failure. Furthermore, VEGF may be a potential target for adjuvant treatment in these patients.

Abstract
BACKGROUND CytoReductive Surgery and Hyperthermic IntraPEritoneal Chemotherapy (CRS-HIPEC) is now the preferred treatment of many peritoneal surface malignancies. In this retrospective study we aimed to analyze how several performance indicators changed during the first 100 CRS-HIPEC procedures in hospitals which recently introduced this treatment, and compare those with an experienced institution. METHODS The first consecutive 100 CRS-HIPEC procedures of three institutions were compared to those of the pioneer hospital. The training provided by the pioneer hospital consisted of hands-on training during the first ten procedures; hereafter guidance was available on consult basis. Operation characteristics, morbidity and completeness of cytoreduction were evaluated by case sequence. Locally-estimated-scatter-plot smoothing was used to evaluate the learning curve. RESULTS From four institutions 372 cases were included. A macroscopic complete cytoreduction was reached in 66% of the cases in the pioneer hospital and in 86% in the new hospitals (p < 0.001). Complete cytoreduction rates were higher at start off in the new institutions compared with the experienced institution and increased significantly in the first 100 procedures. The new hospitals started with lower morbidity than the experienced hospital, which did not significantly decrease during the study period. CONCLUSION New institutions that were trained and mentored by an experienced CRS-HIPEC hospital performed better from the beginning with regard to complete cytoreduction and morbidity rate with than the experienced center. An improvement in complete cytoreduction rate during the first 100 procedures was observed in the new institutions.

Abstract
BACKGROUND Population-based data on the percentage of colorectal cancer (CRC) patients with synchronous peritoneal carcinomatosis (PC) being treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are currently lacking. The current population-based study describes trends in the use of CRS-HIPEC in the Netherlands, one of the first countries where CRS and HIPEC was introduced. METHODS All patients diagnosed with synchronous PC of CRC between 2005 and 2012 were extracted from the Netherlands Cancer Registry (n = 4623). Patients with primary appendiceal cancer were excluded resulting in a study population of 4430 patients. Trends in the use of CRS-HIPEC over time were analyzed by means of a Cochrane-Armitage trend test. Survival proportions were calculated as the time between diagnosis and date of death or last follow-up (January 2014). RESULTS Of the total 4430 patients with synchronous PC, 297 (6.4%) underwent treatment with CRS-HIPEC. The proportion of colorectal PC patients receiving CRS-HIPEC increased significantly over time from 3.6% in 2005-2006 to 9.7% in 2011-2012 (p < 0.0001). Overall median survival (MS) for patients treated with CRS-HIPEC was 32.3 months, whereas MS rates were respectively 12.6, 6.1 and 1.5 for months palliative chemotherapy with/without surgery, palliative surgery and best supportive care. CONCLUSION The proportion of patients diagnosed with synchronous PC from CRC treated with CRS-HIPEC has increased significantly over time and currently almost 10% of PC patients are treated with CRS-HIPEC. Median survival in this population based group is 32.3 months.

Abstract
PURPOSE Oxaliplatin is increasingly becoming the chemotherapeutic drug of choice for the treatment of peritoneal malignancies using cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). Oxaliplatin is unstable in chloride-containing media, resulting in the use of 5% dextrose as the carrier solution in these procedures. Exposure of the peritoneum to 5% dextrose during perfusion times varying from 30 min to 90 min is associated with serious hyperglycemias and electrolyte disturbances. This can result in significant postoperative morbidity and mortality. In order to find out whether safer, chloride-containing carrier solutions can be used, we report the results of in-vitro analysis of oxaliplatin stability in both chloride-containing and choride-deficient carrier solutions and discuss the implications for oxaliplatin-based CRS-HIPEC procedures. METHODS 5 mg of oxaliplatin was added to 50 mL of various carrier solutions at 42 °C: 5% dextrose, 0.9% sodium chloride, Ringer lactate, Dianeal(®) PD4 glucose 1.36% solution for peritoneal dialysis and 0.14 M sterile phosphate buffer pH 7.4. Samples were collected at standardized intervals and oxaliplatin concentration was determined using a stability indicating high-performance liquid chromatographic method, coupled to an UV detector (HPLC-UV); oxaliplatin degradation products were identified using HPLC-mass spectometry. RESULTS In 5% dextrose, oxaliplatin concentration remained stable over a 2-hour period. Increasing chloride concentrations were associated with increasing degradation rates; however, this degradation was limited to <10% degradation after 30 min (the standard peritoneal perfusion time in most clinical CRS-HIPEC protocols) and <20% degradation after 120 min at 42 °C. In addition, oxaliplatin degradation was associated with the formation of its active drug form [Pt(dach)Cl2]. CONCLUSIONS The use of chloride-containing carrier solutions for oxaliplatin does not relevantly affect its concentrations under the tested in-vitro conditions. Chloride seems to promote formation of the active cytotoxic drug form of oxaliplatin and therefore could enhance its cytotoxic effect. These data show that more physiological, chloride-containing carrier solutions can be used safely and effectively as a medium for oxaliplatin in CRS-HIPEC procedures.

Abstract
BACKGROUND Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is the preferred treatment of peritoneal carcinomatosis (PC) of colorectal carcinoma. Patients with positive lymph node status have worse survival after CRS-HIPEC, which is probably due to higher rates of systemic failure. In this study, we analysed the effect of administration and timing of systemic chemotherapy on the outcome of lymph node positive colorectal carcinoma patients treated with CRS-HIPEC. PATIENTS AND METHODS A prospective database was reviewed to identify lymph node positive patients with PC treated with CRS-HIPEC within 1 year after primary tumour diagnosis between 2004 and 2012. Medical history of the patients was studied for the administration of perioperative systemic chemotherapy and follow-up. Outcome parameters were progression-free survival (PFS), overall survival (OS) and pattern of recurrence. RESULTS Seventy-three patients treated with CRS-HIPEC for PC from lymph node positive colorectal carcinoma were identified. Fourteen patients received pre-CRS-HIPEC chemotherapy only, 32 patients underwent post-CRS-HIPEC chemotherapy only, 9 patients received chemotherapy both pre- and post-CRS-HIPEC and 16 patients did not receive any systemic chemotherapy. Of the 47 patients who did not receive pre-CRS-HIPEC chemotherapy, 11 (23%) did not receive any chemotherapy due to major postoperative complications. PFS and OS were significantly higher in patients who received systemic chemotherapy (PFS: median 15 versus 4 months, P = 0.024; OS: median 30 versus 14 months, P = 0.015), although this difference was attenuated after adjustment for major complications. Different chemotherapy timings did not differ significantly in either survival or recurrence patterns. CONCLUSIONS In patients with PC from lymph node positive colorectal carcinoma, perioperative systemic chemotherapy is associated with increased OS and PFS, although this difference may be partly explained by the occurrence of major postoperative complication; with no evidence of difference in PFS, OS and systemic recurrence rate by timing of systemic chemotherapy.

Abstract
Background The purpose of the present study was to evaluate the value of discussing rectal cancer patients in a multidisciplinary team (MDT). Methods All treated rectal cancer patients (>T1M0) diagnosed in 2006–2008 were included. According to the national guidelines, neoadjuvant (chemo)radiotherapy should be given to all rectal cancer patients. Patients were scored as “discussed” (MDT+) only if documented proof was available. The primary endpoint was the number of positive circumferential resection margins (CRM ≤1 mm). Results Of the 275 patients included, 210 were analyzed (exclusions: (recto)sigmoid tumor, acute laparotomy, and inoperability). Neoadjuvant treatment was applied in 174 (83%) patients and followed by total mesorectal excision in 171 (81%) patients. Patients considered not to require downstaging, received short-course radiotherapy (SCRT) (n = 116) or no radiotherapy (no RT) (n = 36), whereas 58 more advanced patients received chemoradiotherapy (CRT). The MDT discussion took place in 116 cases (55%). In the MDT+ group an MRI was used more often (p = 0.001) and TNM staging was more complete (p < 0.001). The proportion of patients with advanced disease was higher in the MDT+ group (88% ≥T3/N+ versus 68%; p = 0.001). The overall CRM+ rate was 13% and did not differ between the MDT+ and the MDT− group (p = 0.392). In patients receiving SCRT or no RT, the CRM+ rate was 10%, whereas the rate was 20% for patients receiving CRT. Conclusions Although no difference in CRM+ rate was found for those patients who were discussed and those who were not, our results demonstrate room for improvement, especially in the selection of patients for SCRT or no RT. We advocate standardized documentation of treatment decisions and pathology reports.

Abstract
Background: Understanding the molecular biology of colorectal cancer (CRC) provides opportunities for effective personalised patient management. We evaluated whether chromosomal aberrations, mutations in the PI(3)K signalling pathway and the CpG-island methylator phenotype (CIMP) in primary colorectal tumours can predict liver metastases. Methods: Formalin-fixed paraffin-embedded material from primary colorectal tumours of three different groups were investigated: patients with CRC without metastases (M0, n=39), patients who were treated with hyperthermal intraperitoneal chemotherapy for CRC metastases confined to the peritoneum (PM, n=46) and those who had isolated hepatic perfusion for CRC metastases confined to the liver (LM, n=48). Results: All samples were analysed for DNA copy number changes, PIK3CA, KRAS, BRAF mutations, CIMP and microsatellite instability. The primary CRCs of the LM group had significantly higher frequency of amplified chromosome 20q (P=0.003), significantly fewer mutations in the PI(3)K signalling pathway (P=0.003) and fewer CIMP high tumours (P=0.05). There was a strong inverse correlation between 20q and the PI(3)K pathway mutations. Conclusion: The development of CRC liver metastases is associated with amplification of chromosome 20q and not driven by mutations in the PI(3)K signalling pathway.

Abstract
BACKGROUND The incidence of ovarian metastases at the time of peritoneal carcinomatosis, and the influence of such metastases on survival after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), are unknown. METHODS This retrospective analysis included 194 women subjected to CRS and HIPEC since 2001. The incidence of ovarian metastases, disease-free survival and disease-specific survival were analysed. RESULTS The histological diagnosis was colorectal cancer carcinomatosis in 108 patients, peritoneal mucinous carcinomatosis (PMCA) in 23 and disseminated peritoneal adenomucinosis (DPAM) in 63. Ninety-nine patients underwent oophorectomy during the HIPEC procedure. Ovarian metastases were confirmed in at least 52 per cent of the patients. There was a significant difference in disease-free survival between women with or without ovarian metastases in both PMCA and DPAM groups (P = 0·044 and P = 0·010 respectively). No significant differences in survival were found in the group with colorectal cancer carcinomatosis. CONCLUSION When peritoneal carcinomatosis of colorectal or appendiceal origin is confirmed, at least 52 per cent of ovaries will have synchronous metastases. Disease-free survival after a HIPEC procedure for PMCA or DPAM is significantly lower in women with ovarian metastases. Oophorectomy during CRS for peritoneal carcinomatosis should be strongly considered.

Abstract
BACKGROUND Delayed gastric emptying (DGE) is a main complication with unknown origin after a cytoreductive surgery and hyperthermic intra-peritoneal chemotherapy (CRS-HIPEC). The aim of this study was to investigate if preservation of the right gastro-epiploic artery (GEA) during standard omentectomy would have a positive effect on gastric emptying after CRS-HIPEC. METHODS Forty-two patients subjected to a CRS-HIPEC were randomized into two groups perioperatively before performing an omentectomy: in Group I (N = 21) omentectomy was performed with preservation of the GEA; in Group II (N = 21) omentectomy was performed with resection of the GEA. The primary endpoint was the number of days to full oral intake of solid food. Secondary endpoints were number of days to intended occlusion of gastrostomy catheter and total hospital admission time. RESULTS No significant differences were discovered between both groups in any of the study endpoints after CRS-HIPEC. No significant differences were observed in patient or operation characteristics between the randomized groups. CONCLUSIONS No association was demonstrated between preservation of the gastro-epiploic artery during omentectomy and gastric emptying after CRS-HIPEC. The extensive intestinal manipulation or the heated intra-peritoneal chemotherapy during surgery are more plausible causes of this phenomenon. This clinical trial was registered in the Netherlands at the Central Committee on Research involving Human Subjects (CCMO) under registration number P06.0301L.

Abstract
BACKGROUND Capecitabine is an attractive radiosensitizer. In this study acute toxicity and surgical complications were evaluated in patients with locally advanced rectal cancer following total mesorectal excision (TME) after preoperative chemoradiotherapy (CRT) with capecitabine. METHODS Between 2004 and 2008, consecutive patients with clinical tumour category (cT) 3-4 (with a threatened circumferential resection margin or cT3 within 5 cm of the anal verge) or clinical node category 2 rectal cancer were treated with preoperative CRT (25 × 2 Gy, capecitabine 825 mg/m(2) twice daily, days 1-33). TME followed 6 weeks later. Toxicity was scored according to the Common Terminology Criteria (version 3.0) and Radiation Therapy Oncology Group scoring systems. Treatment-related surgical complications were evaluated for up to 30 days after discharge from hospital using the modified Clavien-Dindo classification. RESULTS Some 147 patients were analysed. The mean cumulative dose of capecitabine was 95 per cent and 98·0 per cent of patients received at least 45 Gy. One patient died from sepsis following haematological toxicity. Grade 3-5 toxicity developed in 32 patients (21·8 per cent), especially diarrhoea (10·2 per cent) and radiation dermatitis (11·6 per cent). There were no deaths within 30 days after surgery. Anastomotic leakage and perineal wound complications developed after 13 of 47 low anterior resections and 23 of 62 abdominoperineal resections. Surgical reintervention was required in 30 patients. Twenty-seven patients (19·6 per cent) of 138 patients who had a laparotomy were readmitted within 30 days after initial hospital discharge. CONCLUSION Preoperative CRT with capecitabine is associated with acceptable acute toxicity, significant surgical morbidity but minimal postoperative mortality.

Abstract
OBJECTIVE The late revelation of ovarian cancer ensures it as the leading cause of death among gynecologic cancers. Cytoreductive surgery (CRS) and intravenous (i.v.) chemotherapy have been the cornerstone for a long time to treat this disease. More recently, the modality of intraperitoneal administration of chemotherapy under hyperthermic conditions (HIPEC) has been added. This review surveys the results of HIPEC added to CRS in ovarian cancer. METHODS A multi-database search was conducted focusing on mortality, morbidity and overall and disease-free (DF) survival rates. RESULTS 16 studies were identified reporting the results of CRS followed by HIPEC of 546 patients with advanced ovarian cancer. Postoperative mortality was reported for 14 out of 481 patients in total (2.9%). The major morbidity rate varied between 3.4 and 50.0%. In all but one study (533 patients), 185 events were reported (34.5%) and 21 re-interventions after 476 operations (4.4%). Survival data ranged from 10.0 to 57.1 months for the DF survival and from 19.0 to 76.1 months for the overall survival. Optimal cytoreduction and recurrent disease were associated with a better outcome in selected cases. CONCLUSIONS Adding HIPEC to the current treatment modalities for ovarian cancer seems to be feasible. Improved survival rates have been reported at the cost of acceptable mortality rates. Nevertheless, there was a selection bias, the morbidity should not be underestimated and it is unclear yet which patient will benefit most from this treatment. Randomized controlled trials will provide an answer to this question.

Abstract
Background: The aims of this study were to determine which consent procedure patients prefer for use of stored tissue for research purposes and what the effects of consent procedures on actual consenting behaviour are. Methods: We offered 264 cancer patients three different consent procedures: ‘one-time general consent’ (asked written informed consent), ‘opt-out plus’ (had the opportunity to opt out by a form), or the standard hospital procedure (control group). The two intervention groups received a specific leaflet about research with residual tissue and verbal information. The control group only received a general hospital leaflet including opt-out information, which is the procedure currently in use. Subsequently, all patients received a questionnaire to examine their preferences for consent procedures. Results: In all, 99% of patients consented to research with their residual tissue. In the ‘one-time consent’ group 85% sent back their consent form. Patients preferred ‘opt-out plus’ (43%) above ‘one-time consent’ (34%) or ‘opt-out’ (16%), whereas 8% indicated that they did not need to receive information about research with residual tissues or be given the opportunity to make a choice. Conclusions: The ‘opt-out plus’ procedure, which places fewer demands on administrative resources than ‘one-time consent’, can also address the information needs of patients.

Abstract
BACKGROUND Cytoreductive surgery with intraperitoneal chemotherapy has emerged as a new standard approach for peritoneal surface disease. This study investigated the learning curve of this combined modality treatment at a single institute. METHODS Variables analysed over three consecutive treatment periods (1996-1998, 1999-2002 and 2003-2006) included number of abdominal regions affected, Simplified Peritoneal Cancer Index (SPCI) score, result of cytoreduction, morbidity, duration of hospital stay and survival. RESULTS A total of 323 procedures were performed between January 1996 and June 2006, 184 for peritoneal carcinomatosis of colorectal cancer origin and 139 for pseudomyxoma peritonei (PMP), including second procedures in 11 patients with PMP. The mean SPCI score decreased significantly over the study period (P < 0.001), but the number of regions affected did not. The rate of complete cytoreductions increased from 35.6 to 65.1 per cent (P = 0.012). The postoperative morbidity rate decreased from 71.2 to 34.1 per cent (P < 0.001). The median duration of hospital stay decreased from 24 to 17 days. The peak of the learning curve, graded by the percentage of complete cytoreductions, was reached after approximately 130 procedures. CONCLUSION The learning curve of combined modality treatment for peritoneal surface disease is long, and reflects patient selection and treatment expertise.

Abstract
BACKGROUND Pseudomyxoma peritonei (PMP) is a rare disease with an estimated incidence of 1 per million per year, and is thought to originate usually from an appendiceal mucinous epithelial neoplasm. However it is not known exactly how often these neoplasms lead to PMP. The aim of this study is to investigate the incidence of both lesions and their relation. METHODS The nationwide pathology database of the Netherlands (PALGA) was searched for the incidence of all appendectomies, the incidence of primary epithelial appendiceal lesions and the incidence and pathology history of patients with PMP. All regarded the 10-year period of 1995-2005. RESULTS In the 10-year period 167,744 appendectomies were performed in the Netherlands. An appendiceal lesion was found in 1482 appendiceal specimens (0.9%). Nine percent of these patients developed PMP. Coincidentally, an additional epithelial colonic neoplasm was found in 13% of patients with an appendiceal epithelial lesion. A mucinous epithelial neoplasm was identified in 0.3% (73% benign, 27% malignant) of appendiceal specimens and 20% of these patients developed PMP. For mucocele and non-mucinous neoplasm the association with PMP was only 2% and 3%, respectively. From the nationwide database 267 patients (62 men and 205 women) with PMP were identified, which demonstrates an incidence of PMP in the Netherlands approaching 2 per million per year. The primary site was identified in 68% and dominated by the appendix (82%). CONCLUSIONS Primary epithelial lesions of the appendix are rare. One third of these lesions are mucinous epithelial neoplasms and especially these tumours may progress into PMP. The incidence of PMP seems to be higher than thought before. Furthermore there is a considerable risk of an additional colonic epithelial neoplasm in patients with an epithelial neoplasm at appendectomy.

Abstract
Three patients, men aged 47 and 30 and a woman aged 48 years, presented with appendicitis-like symptoms, progressive abdominal distension, and an ovarian pelvic mass, respectively. All three were diagnosed with pseudomyxoma peritonei. Treatment consisted of cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy (HIPEC). After a mean follow-up of 64 months (range: 19-89) after initial treatment, the second patient had died of disease progression but the other two were alive and free of disease. Pseudomyxoma peritonei is a rare disease, characterised by progressive intraperitoneal accumulation of mucinous ascites, produced by a mucinous tumour mass on the peritoneal surfaces. The primary tumour is usually a mucinous adenoma of the appendix. Treatment by cytoreductive surgery and HIPEC can result in a 5-year survival rate of more than 80%, depending on the histopathology and the completeness of the cytoreduction. Recognising pseudomyxoma peritonei in an early stage, when complete cytoreduction is still achievable, may result in a considerable improvement in survival.

Abstract
Pseudomyxoma peritonei (PMP) is a rare condition, which is known for its high mortality when not treated properly. The first step to improve prognosis of these patients is to recognize this clinical syndrome preferably in an early stage. Knowledge of pathogenesis and common diagnostic tools is essential in this regard. Treatment strategy for PMP should pursue complete cytoreduction and prevention of recurrence or progression. Combined modality treatment, consisting of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy, seems very efficient in this regard. This approach is currently carried out in many centers throughout the world with promising results and seems to win ground as the standard treatment approach.

Abstract
AIMS To report on treatment related toxicity and mortality in patients with pseudomyxoma peritonei (PMP) treated by cytoreduction in combination with intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) and to identify prognostic factors. METHODS A review was performed of 103 procedures of cytoreduction and intraoperative HIPEC for PMP between 1996 and 2004. Toxicity was graded according to the National Cancer Institute Common Toxicity Criteria (NCI CTC) classification. A surgical complication was defined as any post-operative event that needed re-intervention. Pre and peroperative factors were studied on their relationship to toxicity and mortality. RESULTS The median hospital stay was 21 days (4-149) with a treatment related toxicity of 54% and a 30 days mortality of 3%. In univariate analysis, toxicity was associated with abdominal tumour load (p<0.01), completeness of cytoreduction (p<0.01), and age (p=0.05). Surgical complications, mainly small bowel perforations/suture leaks, were the main cause of toxicity. A favourable pathology decreased mortality. CONCLUSIONS Cytoreduction in combination with intraoperative HIPEC in PMP patients is a treatment with a relatively high toxicity, but a considerable long-term survival in selected patients. Toxicity is mainly surgery related. Concentration of cases to acquire sufficient experience and better selection on age, pathology, and extent of disease is essential to reduce treatment related toxicity and mortality.

Abstract
AIM A survival benefit has been observed for colorectal cancer patients with peritoneal carcinomatosis treated by cytoreductive surgery with intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC). However, this treatment modality is associated with a considerable morbidity and mortality and in a significant number of patients survival is not improved. We studied whether poor survivors could be identified on preoperative computed tomography (CT), in order to avoid unnecessary surgery. PATIENTS AND METHODS Films of abdominopelvic CT scans from 25 such patients treated by cytoreductive surgery and HIPEC were retrospectively analysed by two radiologists separately. A simplified peritoneal cancer index (SPCI) was used to determine the extent of peritoneal involvement. Correlation between the on preoperative CT based SPCI-scores as well as number of involved abdominopelvic areas (N) and survival was examined with the log-rank test. The relation between each affected region and survival was evaluated with Cox regression analysis. RESULTS The preoperative SPCI- and N-scores of one of the radiologists had no statistically significant prognostic value, while for the second radiologist SPCI > or = 7 and N > or = 4 were associated with particularly poor outcome. Additionally, the presence of ileocaecal region involvement and, depending on the radiologist, the occurrence of tumour deposits in the left subdiaphragmatic area on CT appeared to be unfavourable prognostic signs. CONCLUSIONS The prognostic value of preoperative conventional CT appeared to be radiologist dependent and may, therefore, be of limited value in selecting colorectal cancer patients with peritoneal carcinomatosis who will not benefit from extensive cytoreductive surgery followed by HIPEC.

AIMS To report the results of standard therapy for peritoneal carcinomatosis of colorectal origin, which consists of conventional surgery and systemic chemotherapy. METHOD In a prospective study 50 patients with proven peritoneal carcinomatosis of colorectal origin were treated with conventional surgery combined with 5-fluorouracil and leucovorin, or irinotecan in patients treated by 5-fluorouracil within 12 months prior to entry. Survival and progression-free survival were studied and prognostic factors were analysed. RESULTS The median survival time was 12.6 months. The median time to progression was 7.6 months. Location of primary tumour and result of conventional surgery and systemic chemotherapy were prognostic factors related to survival. CONCLUSION The survival time of patients with peritoneal carcinomatosis of colorectal origin seems to be increased in patients treated by conventional surgery and systemic chemotherapy when compared to minimal treatment.

Abstract
BACKGROUND Pseudomyxoma peritonei (PMP) is a rare clinical syndrome characterized by intraperitoneal accumulation of mucus produced by neoplastic cells of mostly appendiceal origin. The aim of this study was to analyze primary and secondary involvement and treatment-related complications of the urinary tract in PMP. METHODS A retrospective study of 92 patients with PMP, treated by cytoreduction and intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) at The Netherlands Cancer Institute between 1996 and 2004. RESULTS Seven patients presented with involvement of the urinary tract. Major urologic complications occurred in five patients, of which two had secondary involvement of the urinary tract. Major urologic complications consisted predominantly of surgical complications related to the bladder. All patients with secondary involvement and/or urologic complications had undergone previous pelvic surgery. CONCLUSIONS The urinary tract is rarely involved in patients with PMP. Secondary involvement is mostly observed and may be a result of seeding of PMP of pelvic origin after prior pelvic surgery. There is a low urologic complication risk of treatment with cytoreduction and HIPEC. The combination of secondary involvement and previous pelvic surgery is an omen of treatment-related urologic complications, necessitating (surgical) re-interventions and further management in close collaboration with urologists.

Abstract
BACKGROUND Peritoneal carcinomatosis in the absence of distant metastasis occurs in approximately 8 per cent of patients with colorectal cancer. Cytoreduction followed by hyperthermic intraperitoneal chemotherapy (HIPEC) is a new treatment option. Patient selection is crucial to outcome. METHODS Cytoreduction followed by HIPEC was performed in 102 patients with peritoneal carcinomatosis. The following factors were studied for association with survival: perforation and obstruction of the primary lesion, location of the primary lesion, obstruction associated with carcinomatosis, presentation, tumour differentiation and histological type. Extent of disease and completeness of cytoreduction were also studied. Hazard ratios (HRs) were used to study these factors. RESULTS Location of the primary tumour in rectum (HR 3.14 (95 per cent confidence interval (c.i.) 1.11 to 8.91); P = 0.069), poor differentiation (HR 1.73 (95 per cent c.i. 1.04 to 2.88); P = 0.031) and signet cell histological type (HR 2.24 (95 per cent c.i. 1.21 to 4.16); P = 0.008) were associated with shorter survival. Important factors predicting survival were the number of affected regions (HR 1.38 (95 per cent c.i. 1.20 to 1.59); P < 0.001), the simplified peritoneal cancer score (HR 1.19 (95 per cent c.i. 1.12 to 1.26); P < 0.001) and completeness of cytoreduction (HR 8.54 (95 per cent c.i. 4.01 to 18.18); P < 0.001). No other factor correlated with survival. CONCLUSION The survival of patients with peritoneal carcinomatosis of colorectal origin is dominated by the extent of disease and the amount of residual tumour after cytoreduction.

Abstract
AIM The aim of this study was to determine the value of medical history and physical examination, tumour marker testing, and CT-scanning in the follow-up of patients treated for peritoneal carcinomatosis of colorectal origin. METHODS Between November 1995 and June 2003, 107 patients were treated by cytoreduction and hyperthermic intra-peritoneal chemotherapy. The treatment was considered effective if residual tumour after cytoreduction was no thicker than 2.5 mm. The follow-up consisted of history, physical examination, serum CEA and CA 19.9 testing three-monthly, and CT-scanning of the abdomen six-monthly. Location of the recurrence was categorized into intra-abdominal, hepatic, thoracic, and both intra-abdominal and systemic. The investigation that led to the detection of a recurrence was ranked according to its invasiveness and costs. The simplest investigation that could have led to the detection was marked. RESULTS A recurrence developed in 63 patients of the 74 patients effective initial treatment during the study period. Physical examination revealed the recurrence in 38 patients, at least one of the markers was raised above normal value in 39 patients and in 37 patients the CT-scan showed the recurrence. History and physical examination could have triggered the finding of a recurrence in 38 patients, tumour markers in 21 patients and CT-scanning in only three of the 74 recurrences. CONCLUSION Physical examination and tumour marker testing detect most recurrences. CT-scanning is not an effective tool in the follow-up, and should be reserved for on-demand use.

Abstract
AIM Pseudomyxoma peritonei (PMP) is a rare disease characterized by the abundance of mucus in the abdomen without extra-peritoneal growth. METHODS Our patients with PMP have been treated with cytoreduction and hyperthermic intraperitoneal chemotherapy since 1996. The clinical and histopathological features of PMP and the relation of these features with disease-free interval and survival were assessed. RESULTS Sixty-two patients with PMP (24 M/38 F) were studied. Adenomatous mucosal changes were present in 31 patients. In females, the ovaries were normal in 5 patients and pseudomyxoma ovarii was present in 20 patients. Patients with minimal atypia and with 1% focal proliferation or less (n=38) had a better survival (p=0.0008) than those with more focal proliferation (n=14). CONCLUSION In most patients with PMP the appendix is affected; in females the ovaries are usually also involved. Focal proliferation appears to be a prognostic factor.

Abstract
The favorable pharmacokinetics of MMC, used during intraperitoneal chemotherapy, has been reported in several studies [11-19]. A major safety issue in studies using intraperitoneal chemotherapy perfusion is the resulting systemic drug exposure. The AUCplasma is determined by the dose, the clearance, and the fraction absorbed from the peritoneal cavity. The reported mean plasma peak concentrations are about one-third of the systemic exposure following a therapeutic dose of MMC given by intravenous administration [30]. The best method to quantify the exposure to MMC are the time concentration profiles (AUC). Because MMC can still be found in plasma the day after intraperitoneal administration, the AUC0-90 is an underestimate of the real AUC; extrapolation to infinity gives the most reliable AUCplasma value. In our series the AUCplasma is about half the AUCplasma when given a therapeutic dose MMC intravenously [30]. What is the best dose in intraperitoneal chemotherapy perfusion? The ideal amount of MMC should include a high AUCperfusate, a high AUCplasma and an acceptable systemic toxicity. In our series grade III/IV leucopenia was observed in 28% patients. We find this rather high percentage acceptable as the problem has proved to be transient, and we have experienced no toxic deaths in recent years. In a phase I study it was estimated that a dose of 25 mg/m2 would result in approximately 10% of grade III/IV leucopenia [20]. Our data indicate that dosing based on body surface area is rational and reliable. The variation between individuals is low. Dosing based on a fixed concentration per liter perfusion fluid is probably more liable to have unforeseen variations, given the fact that we deal with linear pharmacokinetics of MMC [20]. As represented in Fig. 3, the dose of MMC can best be administered in three divided doses, resulting in the more equal exposure of peritoneal structures to MMC during the perfusion. It must be emphasized that our findings only hold true for the perfusion system as used in The Netherlands Cancer Institute. This involves a semi-open abdomen, basic perfusate volume of 3 L, perfusion rate of 1 L/min, abdominal temperature of 40 degrees C, 90 minutes of perfusion, and three drug additions (50% at t = 0, 25% at t = 30 and t = 60 minutes). The differences in perfusion techniques make comparisons of published pharmacokinetics data difficult. Cautions comparison suggest that most groups are dosing far below the maximal tolerated dose. We assume that there is a dose-effect relation for MMC. This means that obtaining a maximal safe dose is important to get maximal results. It seems that better dosing of intraperitoneal MMC can still improve results. The pharmacokinetics of intraperitoneal MMC can, however, be influenced by many details. Open or closed perfusion for instance may make some essential differences. It is therefore important that each treatment group performs its own pharmacokinetics studies on intraperitoneal MMC to achieve the optimal dose method for their chemotherapy perfusion setting. In conclusion, the major advantage of intraperitoneal chemotherapy is the regional dose intensity provided. Following intraperitoneal MMC administration, the affected peritoneal surface is exposed to high concentrations while the systemic toxicity is limited. Comparative analyses on MMC pharmacokinetics are difficult to perform because the diversity of treatment techniques. We recommend administration of MMC, divided in three drug additions, based on BSA.

Abstract
BACKGROUND Tumor markers are useful for diagnosis and follow-up. We studied the prognostic value of baseline and serial carcinoembryonic antigen (CEA) and carbohydrate antigen 19.9 (CA19.9) measurements in patients with pseudomyxoma peritonei treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS Sixty-three patients with pseudomyxoma peritonei were treated with cytoreductive surgery and HIPEC. The tumor markers CEA and CA19.9 were collected before therapy and at 3-month intervals during follow-up. RESULTS Preoperative CEA and CA19.9 levels were increased in, respectively, 75% and 58% of the patients. Baseline tumor marker values were related to the extent of tumor. Immediately after HIPEC, both tumor markers decreased markedly (P <.0001). CA19.9 was shown to be a more useful tumor marker than CEA for follow-up. During follow-up, a high absolute CA19.9 level (P =.0005) was predictive for imminent recurrence. Patients who never attained a normal CA19.9 level showed a higher recurrence rate at 1 year (53%; SE, 15%), in comparison to patients who did so (6%; SE 4%). The median lead time of increased CA19.9 to recurrence was 9 months. CONCLUSIONS The measurement of the tumor marker CA19.9 is useful in evaluating therapy in patients with pseudomyxoma peritonei treated with cytoreductive surgery and HIPEC. CA19.9 is a prognostic factor for predicting recurrent disease.

Abstract
BACKGROUND Hyperthermic intraperitoneal chemotherapy (HIPEC) with mitomycin C has been applied following cytoreductive surgery for various peritoneal surface malignancies. The aim of this study was to evaluate heat penetration in the abdomen during 10 HIPEC procedures. MATERIALS AND METHODS Temperature measurements were taken at 5 levels through the abdominal wall. Core temperature and room temperature were also measured. The relationships between the temperature gradient and room or core temperature were studied. RESULTS At the start of perfusion, the temperature was estimated on average to be 40.6 degrees C at the first level, then it decreased by 1.7 degrees C (SD 1.0 degree C, p = 0.0001) in the first mm. In outward direction, it decreases by a further 1.5 degrees C per cm (SD 0.3 degree C/cm, p < 0.0001). The core temperature influenced the temperature gradient; the room temperature was not found to be a significant factor. At the end of perfusion, the temperature is estimated on average to be 40.1 degrees C at the first level, then it decreased by 0.8 degree C (SD 0.7 degree C, p = 0.011) in the first mm. In an outward direction, it decreased by a further 1.7 degrees C per cm (SD 0.4 degree C/cm, p = 0.0001). No evidence of an association between the temperature gradient and the room temperature or the core temperature was observed. CONCLUSION Hyperthermia used during HIPEC procedures has a limited penetration depth. The slope in temperature seems to be related to the core temperature.

Abstract
BACKGROUND Malignant pleural mesothelioma (MPM) is a disease mostly confined to the thoracic cavity. Untreated, the median survival is <1 year. Cytoreductive surgery combined with intraoperative hyperthermic intrathoracic chemotherapy is used to kill residual tumor cells on the surface of the thoracic cavity while having limited systemic side effects. METHODS From August 1998 to August 2001, 22 patients with stage I MPM were included in this study. Two patients were irresectable at operation because of extrathoracic tumor growth. Twenty procedures were performed. After cytoreduction, a perfusion was performed with cisplatin and doxorubicin at 40 degrees C to 41 degrees C for 90 minutes. Adjuvant radiotherapy was given to surgical scars and drainage tracts. RESULTS There was no perioperative mortality, but significant morbidity was seen in 13 patients (65%), including bronchopleural fistula, diaphragm rupture, wound dehiscence, persistent air leakage, and chylous effusion. No hair loss or leucopenia was noticed. The median follow-up was 14 months. The median survival (Kaplan-Meier) was 11 months, with a 1-year survival of 42%. A favorable pharmacokinetic ratio was observed for both cisplatin and doxorubicin. CONCLUSIONS Cytoreductive surgery combined with hyperthermic intrathoracic chemotherapy for stage I MPM is feasible. However, this treatment is accompanied by considerable morbidity. Survival data were less encouraging.

Abstract
Cytoreductive surgery combined with intraoperative hyperthermic intrathoracic chemotherapy (HITHOC) is studied in a phase I study in the treatment of malignant pleural mesothelioma and pleural thymoma. We studied the pharmacokinetics of doxorubicin and cisplatin used during the HITHOC procedure. Furthermore, the penetration characteristics of doxorubicin were examined. Between 1998 and 2001, 24 perfusions were performed with a solution containing doxorubicin and cisplatin for 90 min at 40-41 degrees C. The dose was first based on square meters body surface, whereas in later studies a fixed concentration of the perfusion fluid was used. Samples of blood and perfusion fluid were collected for doxorubicin and cisplatin measurements. The penetration characteristics of doxorubicin in tissue were determined by fluorescence microscopy. The mean AUC(perfusate):AUC(plasma) ratios for doxorubicin and cisplatin (ultrafiltration for plasma) were 99 and 59, respectively. During perfusion the concentration in the perfusate declined essentially according to first-order elimination kinetics for both doxorubicin and cisplatin with half-lives of 74 and 138 min, respectively. At the end of the perfusion, about 35 and 52% of the dose of doxorubicin and cisplatin, respectively, was recovered in the perfusion fluid. One patient developed a nephrotoxicity grade II. No leukopenia or hair loss was seen. Doxorubicin penetrated into the intercostal muscle specimen, albeit that there was considerable variation in distribution throughout the specimen. We conclude that HITHOC with doxorubicin and cisplatin is relatively a safe procedure with the advantage of high intrathoracic cytostatic drug concentrations, while having limited systemic side effects.

Abstract
Abstract
Background
This study determined whether relaparotomy has a positive or negative effect on prognostic scoring systems.
Methods
Between April 1995 and January 1997, 46 patients with abdominal sepsis were treated. The diagnosis of abdominal sepsis was defined as meeting the Bone criteria for sepsis before operation, in combination with infection of the abdomen proven by laparotomy. After the first laparotomy there were 41 relaparotomies in these 46 patients. From 2 days before to 3 days after the relaparotomy, data were collected to compile the Acute Physiology and Chronic Health Evaluation (APACHE) III and Multiple Organ Failure (MOF) scores. The scores were compared before and after relaparotomy, and were also compared between patients who had a recurrent infection in the abdomen and those who did not.
Results
During 41 relaparotomies, 16 patients were found to have a pus collection. Of these clinical infections only 11 had a positive culture. Overall the APACHE III and MOF scores were not significantly different before and after operation. In patients with clinical infection there was also no difference pre and post operative. The same applied for patients with and without positive intraabdominal cultures.
Conclusion
Relaparotomy in patients with abdominal sepsis did not have a negative effect on prognosis within a few days after reoperation. The authors did not find any reason to use APACHE III or MOF scoring as an indication for relaparotomy.

Abstract
Retrospectively, the first 143 patients who were operated on with bilateral internal thoracic arteries (BITA group) were matched with 143 patients operated on with only one left internal thoracic artery anastomosed on the left anterior descending artery and additional vein grafts (LITA group) and followed up for a maximum of 8 years. At 5 years follow-up there were no significant differences in event-free survival between the groups. After 8 years, the overall survival was 96% and 92% (not significant [NS]), cardiac survival 99% and 97% (NS), angina-free cardiac survival 51% and 35% (NS), infarction-free cardiac survival 95% and 78% (NS), reintervention-free cardiac survival 87% and 88% (NS), and all cardiac event-free survival 49% and 31% (NS) for the BITA and LITA groups, respectively. The incidence of late pulmonary, wound, and other complications was comparable. Cox proportional hazards analysis showed that a higher left ventricular end-diastolic pressure and female sex were predictors of recurrent angina and late cardiac events. During this intermediate-term follow-up, the use of one or two internal thoracic arteries was of no value in predicting angina-free or cardiac event-free survival.

Abstract
The hospital morbidity and mortality of 100 patients operated with two internal thoracic arteries with or without additional vein grafts (BITA group) were compared with a matched group of 100 patients operated with one left internal thoracic artery (ITA) on the anterior descending artery with additional vein grafts (LITA control group). In each study group, 3% of the patients had diabetes mellitus. There was no statistical significant difference in hospital mortality (1% versus 0%), perioperative myocardial infarction (5% versus 1%), low cardiac output (3% versus 5%), rethoracotomy (1% versus 0%), lung complications (13% versus 13%), wound complications (8% versus 8%), other cardiac complications (26% versus 16%), other noncardiac complications (1% versus 4%), median duration of stay in the intensive care unit (1 versus 1 day), and mean duration of stay in the hospital (10.4 versus 10.8 days) between the groups. Logistic regression analysis showed that the number of ITAs used was not a predictor of complications. Thus, there is no difference between the BITA and LITA control group in hospital mortality and morbidity (in patients with a low incidence of diabetes). If an improvement in cardiac event-free and reoperation-free survival is to be expected, the use of both ITAs can be continued in similar patients.

Abstract
OBJECTIVE To find out if there was an association between perioperative blood transfusion and the development of infective complications, and whether the use of the cell saver for autologous transfusion had any influence. DESIGN Retrospective study. SETTING University Hospital. SUBJECTS 102 consecutive patients who had been operated on for aneurysms of the abdominal aorta. MAIN OUTCOME MEASURES Morbidity and mortality. RESULTS 32 of the 102 patients developed infective complications. Thirteen patients died (six after emergency and seven after elective operations). Nine died as a direct result of infection, one of intra-abdominal bleeding, one of necrosis of the colon, and two of cardiopulmonary complications. The incidence of infective complications was directly related to the number of units of blood transfused, being 0 when 0 or 1 was given; 11 (20%) when 2-4 units were given; 12 (55%) when 5-8 units were given; and 9 (69%) when the number was 9 or more. The cell saver had no influence on the incidence. Other factors associated with higher rates of infective complications were the insertion of a bifurcated prosthesis (p = 0.03), and emergency operation (p < 0.001). CONCLUSION These results confirm the association between blood transfusion and the incidence of infective complications. It may be that more intensive use of the cell saver and preoperatively saved autologous blood could reduce the rate of infective complications.
