This multicentre pilot study investigated the role of peroperative carcinoembryonic antigen (CEA)-specific fluorescence imaging during cytoreductive surgery-hyperthermic intraperitoneal chemotherapy surgery in peritoneal metastasized colorectal cancer. A correct change in peritoneal carcinomatosis index (PCI) owing to fluorescence imaging was seen in four of the 14 included patients. The use of SGM-101 in patients with peritoneally metastasized colorectal carcinoma is feasible, and allows intrao ...[more]

Project description:Gastric cancer associated peritoneal carcinomatosis (GCPC) has a poor prognosis with a median survival of less than one year. Systemic chemotherapy including targeted agents has not been found to significantly increase the survival in GCPC. Since recurrent gastric cancer remains confined to the abdominal cavity in many patients, regional therapies like aggressive cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been investigated for GCPC. HIPEC has been used for three indications in GC- as an adjuvant therapy after a curative surgery, HIPEC has been shown to improve survival and reduce peritoneal recurrences in many randomised trials in Asian countries; as a definitive treatment in established PC, HIPEC along with CRS is the only therapeutic modality that has resulted in long-term survival in select groups of patients; as a palliative treatment in advanced PC with intractable ascites, HIPEC has been shown to control ascites and reduce the need for frequent paracentesis. While the results of randomised trials of adjuvant HIPEC from western centres are awaited, the role of HIPEC in the treatment of GCPC is still evolving and needs larger studies before it is accepted as a standard of care.

Project description:The management of peritoneal metastases from gastric cancer origin has evolved considerably over the last three decades with the establishment of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) as efficacious therapies in carefully selected patients. Other approaches such as the use of prophylactic/adjuvant HIPEC in patients who are considered high-risk and those with positive peritoneal cytology will benefit from additional data before being adopted into routine clinical practice. Lastly, there are new and emerging intraperitoneal chemotherapy techniques such as early post-operative intraperitoneal chemotherapy (EPIC) for residual microscopic disease, and pressurized intraperitoneal aerosolized chemotherapy (PIPAC) for patients with advanced unresectable peritoneal carcinomatosis, which are currently under evaluation in clinical trials. The following review outlines the natural history of gastric cancer, currently available neoadjuvant and adjuvant therapies for resectable disease, and existing evidence supporting various approaches to CRS and intraperitoneal chemotherapy.

Project description:Liver resection has long been considered the standard of care for resectable colorectal hepatic metastases (HM). Patients with colorectal peritoneal surface disease (PSD) are now also being treated with aggressive therapy in the form of cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy (HIPEC).A retrospective comparison of optimally-treated colorectal cancer patients with HM or PSD obtained from prospectively maintained databases (1991-2010).Liver resection was performed on 179 patients with HM, while 93 PSD patients received a complete cytoreduction followed by HIPEC. Patients differed in terms of age, performance status, site of primary cancer, T stage, and the use of perioperative chemotherapy. Five-year overall survival for HM patients was 36 %, with a median survival of 46 months, compared with 26 % and 34 months in patients with PSD (p = 0.024). When stratified by resection status, R0 HM (n = 170) and R0 PSD (n = 48) patients had similar median survival (49 vs. 41 months; p = 0.39). Median survival following R1 resection was also similar among HM (n = 9) and PSD (n = 45) patients (28 vs. 23 months; p = 0.68). Multivariate analysis identified distinctly different independent prognostic factors between HM and PSD patients. Major morbidity was 21 and 23 % (p = 0.88), while mortality was 3.9 versus 5.4 % (p = 0.55) in the HM and PSD patients, respectively.Colorectal HM and PSD are distinct biologic diseases with different presentations and unique prognostic factors. However, long-term survival following CS/HIPEC is comparable to liver resection when stratified by completeness of resection. Furthermore, perioperative morbidity and mortality are similar.

Project description:BackgroundPatients 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 methodsClinicopathological 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.ResultsUnivariate 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).ConclusionsAn 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.

Project description:ImportanceStudies on the prognostic role of hyperthermic intraperitoneal chemotherapy (HIPEC) in pseudomyxoma peritonei (PMP) are currently not available.ObjectivesTo evaluate outcomes after cytoreductive surgery (CRS) and HIPEC compared with CRS alone in patients with PMP.Design, setting, and participantsThis cohort study analyzed data from the Peritoneal Surface Oncology Group International (PSOGI) registry, including 1924 patients with histologically confirmed PMP due to an appendiceal mucinous neoplasm. Eligible patients were treated with CRS with or without HIPEC from February 1, 1993, to December 31, 2017, and had complete information on the main prognostic factors and intraperitoneal treatments. Inverse probability treatment weights based on the propensity score for HIPEC treatment containing the main prognostic factors were applied to all models to balance comparisons between the CRS-HIPEC vs CRS-alone groups in the entire series and in the following subsets: optimal cytoreduction, suboptimal cytoreduction, high- and low-grade histologic findings, and different HIPEC drug regimens. Data were analyzed from March 1 to June 1, 2018.InterventionsHIPEC including oxaliplatin plus combined fluorouracil-leucovorin, cisplatin plus mitomycin, mitomycin, and other oxaliplatin-based regimens.Main outcomes and measuresOverall survival, severe morbidity (determined using the National Cancer Institute Common Terminology for Adverse Events, version 3.0), return to operating room, and 30- and 90-day mortality. Differences in overall survival were compared using weighted Kaplan-Meier curves, log-rank tests, and Cox proportional hazards multivariable models. A sensitivity analysis was based on the E-value from the results of the main Cox proportional hazards model. Differences in surgical outcomes were compared using weighted multivariable logistic models.ResultsOf the 1924 patients included in the analysis (997 [51.8%] men; median age, 56 [interquartile range extremes (IQRE), 45-65] years), 376 were in the CRS-alone group and 1548 in the CRS-HIPEC group. Patients with CRS alone were older (median age, 60 [IQRE, 48-70] vs 54 [IQRE, 44-63] years), had less lymph node involvement (14 [3.7%] vs 119 [7.7%]), received more preoperative systemic chemotherapy (198 [52.7%] vs 529 [34.2%]), and had higher proportions of high-grade disease (179 [47.6%] vs 492 [31.8%]) and suboptimal cytoreduction residual disease (grade 3, 175 [46.5%] vs 117 [7.6%]). HIPEC was not associated with a higher risk of worse surgical outcomes except with mitomycin, with higher odds of morbidity (1.99; 95% CI, 1.25-3.19; P = .004). HIPEC was associated with a significantly better overall survival in all subsets (adjusted hazard ratios [HRs], 0.60-0.68, with 95% CIs not crossing 1.00). The weighted 5-year overall survival was 57.8% (95% CI, 50.8%-65.7%) vs 46.2% (95% CI, 40.3%-52.8%) for CRS-HIPEC and CRS alone, respectively (weighted HR, 0.65; 95% CI, 0.50-0.83; P < .001; E-value, 2.03). Such prognostic advantage was associated with oxaliplatin plus fluorouracil-leucovorin (HR, 0.42; 95% CI, 0.19-0.93; P = .03) and cisplatin plus mitomycin (HR, 0.57; 95% CI, 0.42-0.78; P = .001) schedules.Conclusions and relevanceIn this cohort study, HIPEC was associated with better overall survival when performed after CRS in PMP, generally without adverse effects on surgical outcomes.

Project description:Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy has emerged as one of the primary modalities of treatment of diffuse peritoneal malignancies. It is a complex surgical procedure with the patients facing major and potentially life threatening alterations of haemodynamic, respiratory, metabolic and thermal balance with significant fluid losses and the perioperative management is challenging for anaesthesiologists and intensive care physicians. Though the alterations are short lived, these patients require advanced organ function monitoring and support perioperatively. The anaesthesiologist is involved in the management of haemodynamics, respiratory function, coagulation, haematologic parameters, fluid balance, thermal variations, and metabolic and nutritional support perioperatively. The chemotherapy instillate used are known to cause nephrotoxicity, cardiotoxicity, dyselectrolytemia and lactic acidosis. The preoperative polypharmacy for pain control, previous surgery and/or chemotherapy, malnourished status secondary to feeding problems and tumour wasting syndrome make the task all the more challenging. The anaesthesiologist also needs to consider the perioperative care from a quality of life perspective and proper preoperative counselling is important. The present overview summarizes the challenges faced by the anaesthesiologist regarding the pathophysiological alterations during the Cytoreductive surgery and Hyperthermic intraperitoneal chemotherapy in the preoperative, intraoperative and postoperative periods.

Project description:BackgroundSecondary cytoreductive surgery (CRS) can afford promising results in patients with recurrent ovarian cancer; however, the impact of hyperthermic intraperitoneal chemotherapy (HIPEC) remains unclear. We compared the outcomes of secondary CRS combined with and without HIPEC in patients with recurrent ovarian cancer.MethodsWe retrospectively evaluated patients with recurrent ovarian cancer who underwent secondary CRS, with or without HIPEC (n=46), at the Yonsei Cancer Center between January 2006 and February 2021. Of the 46 included patients, 20 underwent secondary CRS-plus-HIPEC, while 26 underwent secondary CRS without HIPEC (henceforth referred to as secondary CRS-only).ResultsOf the 46 patients, 84.8% and 89.1% had undergone optimal surgery and platinum-based chemotherapy, respectively, as the initial treatment before the first relapse. Overall, 32.6% of patients received maintenance therapy, such as bevacizumab or polyadenosine diphosphate ribose polymerase inhibitors. The median follow-up period was 15.9 months. The median progression-free survival (PFS) was 32.7 and 25.1 months in the secondary CRS-plus-HIPEC and secondary CRS-only groups, respectively; however, both groups failed to reach the median overall survival (OS). Based on the Kaplan-Meier analysis, there was no difference in PFS (P=0.587) or OS (P=0.239) between the two groups. We identified patients with epithelial ovarian cancer and found that the median PFS was 25.1 months in the secondary CRS-only group; this was not achieved in the secondary CRS-plus-HIPEC group (P=0.244).ConclusionsIn patients with recurrent ovarian cancer, secondary CRS with HIPEC did not improve survival when compared with CRS without HIPEC. However, on subgrouping patients with epithelial ovarian cancer, the addition of HIPEC to secondary CRS tended to improve PFS.

Project description:BackgroundPreoperative bevacizumab has been reported to increase postoperative complication risk following cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). We sought to review our experience with preoperative bevacizumab in patients undergoing CRS/HIPEC for peritoneal surface malignancy.MethodsThis is a retrospective review of patients who received neoadjuvant systemic therapy with or without bevacizumab prior to CRS/HIPEC at a high-volume academic center from 2007-2018.ResultsOf 499 patients, a total of 88 patients received neoadjuvant chemotherapy alone (n = 34) or in combination with bevacizumab (n = 54) within 3 months prior to CRS/HIPEC. No differences existed in 60-day major morbidity (17.6 vs. 16.7%, p = 0.81) or 60-day mortality (0 vs. 0%) between the two cohorts, and neoadjuvant bevacizumab was not associated with increased odds of overall complications (OR 0.86, 95% CI 0.35-2.09, p = 0.73) or major morbidity (OR 0.86, 95% CI 0.24-3.00, p = 0.81). Stratifying patients by primary tumor origin and post-operative complications did not reveal any significant differences between the two treatment groups. In addition, progression-free survival (PFS) and overall survival (OS) were similar in both cohorts.ConclusionsPreoperative bevacizumab is not associated with increased morbidity or mortality following CRS/HIPEC. Neoadjuvant therapy employing this biologic agent is safe and should not be a deterrent for aggressive cytoreduction with curative intent.

Project description:IntroductionCytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is a well-established treatment for peritoneal cancer (PC). However, this kind of combination therapy is associated with a high incidence of complications. Moreover, relative studies have indicated that traditional laboratory testing is insufficient to demonstrate the overall haemostatic physiology of CRS/HIPEC. Thromboelastography (TEG), administered by monitoring dynamic changes in haemostasis, has been shown to contribute to reducing transfusion requirements and improving survival. However, there is no evidence to verify whether TEG can be applied to guide transfusion strategies during CRS/HIPEC. Therefore, we aim to investigate whether TEG-guided blood product transfusion (TEG-BT) therapy is superior to traditional blood product transfusion (T-BT) therapy for guiding perioperative blood transfusion treatment and improving the prognosis of patients undergoing CRS/HIPEC.Methods and analysisThe TEG-BT versus T-BT study is a single-centre, randomised, blinded outcome assessment clinical trial of 162 patients with PC, aged 18-64 years and undergoing CRS/HIPEC. Participants will be randomly allocated to receive TEG-BT or T-BT. The primary outcome will be the evaluation of perioperative blood transfusion, which refers to the total amount of blood transfusion given from the time patients enter the operating room up to 72 hours postoperatively. The secondary outcomes will include the transfusion volume during surgery, total amount of intraoperative infusion, amount of blood lost during the operation, total blood transfusion between 0 and 72 hours after surgery, lowest haemoglobin level within 72 hours after surgery, intensive care unit duration, overall length of stay, total cost of hospitalisation and adverse events. Data will be analysed according to the intention-to-treat principle.Ethics and disseminationThe study protocol has been approved by the Scientific Research Ethics Committee of Beijing Shijitan Hospital Affiliated with Capital Medical University (Approval Number: sjtkyll-lx-2020-3). The results will be published in peer-reviewed journals.Trial registration numberChinese Clinical Trial Registry (ChiCTR2000028835).

Project description:Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) has an emerging role in the treatment of peritoneal malignancies. The CRS-HIPEC approach has known treatment-related toxicities. This study sought to determine the predictors of major postoperative complications after CRS-HIPEC in a high-volume center.From a single-institution database, this study investigated complications experienced by patients undergoing CRS-HIPEC. Multiple preoperative and operative factors were analyzed for their ability to predict 60-day Clavien grade 3 and greater (major) complications by logistic regression. A predictive model was created from preoperative factors using multivariate logistic regression. The model was tested by Akaike's information criterion, the Hosmer and Lemeshow Goodness-of-Fit Test, the receiver operating characteristic, and the Youden Index.The study evaluated 247 patients undergoing CRS-HIPEC. The primary tumor site was the appendix in 166 cases (67.2 %), the colorectal area in 51 cases (20.6 %), the peritoneum (mesothelioma) in 22 cases (8.9 %), the ovary in 5 cases (2 %), and the small bowel in 3 cases (1.2 %). The median peritoneal cancer index was 14 (range 0-29), and 235 patients (95.1 %) had a complete (CC-0/1) cytoreduction. Major complications occurred for 41 patients (16.6 %), classified as grade 3 in 33 cases (13.4 %), grade 4 in 5 cases (2 %), and grade 5 (deaths) in 3 cases (1.2 %). The factors predictive of major complications in the multivariate analysis were a Charlson Comorbidity Index (CCI) score higher than 0 [odds ratio (OR), 2.505; p = 0.035], presence of preoperative symptoms (OR 1.951; p = 0.064), and prior resection status [no resection or prior CRS-HIPEC (OR 2.087) vs. prior resection without CRS-HIPEC (OR 3.209); p = 0.046]. These variables were used to create a tool predictive of postoperative complications.Presence of symptoms, CCI, and prior resection status predict major complications and define a low-risk population after CRS-HIPEC.
