A phase Ib randomized multicenter trial of isolated hepatic perfusion in combination with ipilimumab and nivolumab for uveal melanoma metastases (SCANDIUM II trial).

BACKGROUND: Uveal melanoma (UM) is a rare malignancy where 50% of patients develop metastatic disease primarily affecting the liver. Approximately 40% of patients with metastatic UM respond to one-time isolated hepatic perfusion (IHP) with high-dose melphalan. This phase I trial investigates the safety and clinical efficacy of IHP combined with ipilimumab (IPI) and nivolumab (NIVO). PATIENTS AND METHODS: Immunotherapy-naïve patients were randomized in this phase I trial to receive either IHP followed by IPI 3 mg/kg and NIVO 1 mg/kg (IPI3/NIVO1) for four cycles (post-operative arm), or one cycle of preoperative IPI3/NIVO1, IHP and then three cycles of IPI3/NIVO1 (pre-post-operative arm), followed by maintenance therapy with NIVO 480 mg for 1 year. RESULTS: Eighteen patients were enrolled and randomized. Three patients did not undergo IHP as planned. In total, 11/18 patients (6 in the post-operative arm and 5 in the pre-post-operative arm) did not complete the planned four cycles of IPI3/NIVO1. Toxicity to IHP was similar in both groups, but the number of immune-related adverse events (AEs) was higher in the pre-post-operative arm. Among assessable patients, overall response rate was 57% in the post-operative arm (4/7) and 22% in the pre-post-operative arm (2/9). CONCLUSIONS: Combination therapy with IHP and IPI3/NIVO1 was associated with severe AEs. The efficacy of this combination is encouraging with high response rates. One cycle of preoperative IPI/NIVO before IHP did not show potential benefits in terms of safety or efficacy.

Efficacy and safety of intrapleural perfusion with hyperthermic chemotherapy for malignant pleural effusion: a meta-analysis.

OBJECTIVE: To evaluate the efficacy and safety of intrapleural perfusion with hyperthermic chemotherapy (IPHC) in treating malignant pleural effusion (MPE). METHODS: PubMed, Embase, Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), VIP Chinese Science and Technology Journal Full-text Database (VP-CSJFD), and Wanfang database were searched by computer from database establishment to January 17, 2024. Relevant randomized controlled articles with IPHC as the observational group and intrapleural perfusion chemotherapy (IPC) as the control group for MPE were included. Then, the methodological quality of the included articles was evaluated and statistically analyzed using Stata 16.0. RESULTS: Sixteen trials with 647 patients receiving IPHC and 661 patients receiving IPC were included. The meta-analysis found that MPE patients in the IPHC group had a more significant objective response rate [RR = 1.31, 95%CI (1.23, 1.38), P < 0.05] and life quality improvement rate [RR = 2.88, 95%CI (1.95, 4.24), P < 0.05] than those in the IPC group. IPHC and IPC for MPE patients had similar incidence rates of asthenia, thrombocytopenia, hepatic impairment, and leukopenia. CONCLUSION: Compared with IPC, IPHC has a higher objective response rate without significantly increasing adverse reactions. Therefore, IPHC is effective and safe. However, this study is limited by the quality of the literature. Therefore, more high-quality, multi-center, large-sample, rigorously designed randomized controlled clinical studies are still needed for verification and evaluation.

Liver Resection Under Total Hepatic Vascular Exclusion with In Situ Hypothermic Isolated Hepatic Perfusion for Advanced Liver Tumors.

PURPOSE: Continuous dissection or simultaneous reconstruction of the hepatic vein (HV) and inferior vena cava (IVC) was achieved under total hepatic vascular exclusion (THVE) with in situ hypothermic isolated hepatic perfusion (HIHP) in two cases. CASE 1: The patient previously underwent liver resections with the right HV for colorectal liver metastasis (CRLM). This time, the CRLM had invaded the left HV and IVC, and five courses of FOLFILI plus ramucirumab were given, resulting in stable disease. Due to expected high HV pressure, liver parenchymal transection was started under THVE. Sub-segmentectomy with patch graft plasty of the IVC and reconstruction of the left HV using a jugular vein graft were performed under THVE and HIHP. This patient died at home 3 months after surgery; the cause of death was unknown. CASE 2: Hepatocellular carcinoma in the caudate lobe was in extensive contact with the roots of three main HVs and the IVC, and pressed the hepatocaval confluence, with high HV pressure expected. In addition, tumor thrombosis extended to both the main portal vein and the common bile duct, resulting in the inability to introduce chemotherapy. After tumor thrombectomy, liver parenchymal transection was started under THVE. Extended left hepatectomy with wedge resection, and primary suture of the right HV and IVC was performed under THVE and HIHP. Recurrence-free and overall survivals were 8 months (lung metastasis) and 31 months, respectively. CONCLUSIONS: In liver resection for liver tumors located in the hepatocaval confluence, THVE with HIHP is useful for ensuring the safety.

Quality of Life Analysis of Patients Treated with Percutaneous Hepatic Perfusion for Uveal Melanoma Liver Metastases.

PURPOSE: Percutaneous hepatic perfusion with melphalan (M-PHP) is a minimally invasive therapy with proven efficacy in patients with uveal melanoma (UM) liver metastases. M-PHP is associated with a short hospital admission time and limited systemic side effects. In this study, we assessed quality of life (QoL) in UM patients treated with M-PHP. MATERIALS AND METHODS: A prospective, single-center study including 24 patients treated with M-PHP for UM metastases to the liver. QoL questionnaires were collected at baseline, on day 2/3 after M-PHP, and on day 7 and day 21 after M-PHP, according to study protocol. The results were scored according to EORTC-QLQ C30 global health status (GHS), functional scales, and symptom scales. The difference in scores at baseline and subsequent time points was analyzed with the Wilcoxon signed-rank test and multiple testing Bonferroni correction. Adverse events (AE) were registered up to 30 days after M-PHP according to CTCAE v5.0. RESULTS: Twenty-four patients (14 males; median age 63.0 years) completed 96 questionnaires. Most scores on all scales declined on day 2/3 after M-PHP. On day 21 after M-PHP, 12 out of 15 scores returned to baseline, including median GHS scores. Three variables were significantly worse on day 21 compared to baseline: fatigue (6-33; p = 0.002), physical functioning (100 vs 86.7; p = 0.003), and role functioning (100 vs 66.7; p = 0.001). Grade 3/4 AEs consisted mainly of hematological complications, such as leukopenia and thrombopenia. CONCLUSION: M-PHP causes fatigue and a decline in physical and role functioning in the 1st weeks after treatment, but GHS returns to baseline levels within 21 days. LEVEL OF EVIDENCE 3: Cohort study.

Troponin Elevation in Patients Undergoing Percutaneous Hepatic Perfusion for Metastatic Uveal Melanoma.

BACKGROUND: Percutaneous Hepatic Perfusion (PHP) is a liver directed regional therapy recently FDA approved for metastatic uveal melanoma to the liver involving percutaneous isolation of liver, saturation of the entire liver with high-dose chemotherapy and filtration extracorporeally though in line filters and veno-venous bypass. The procedure is associated with hemodynamic shifts requiring hemodynamic support and blood product resuscitation due to coagulopathy. OBJECTIVE: To assess the cardiac safety and subsequent clinically significant sequalae of this therapy. METHODS: Consecutive PHP procedures done at our center between 2010-2022 were assessed retrospectively. Cardiac risk factors, post procedural cardiac enzymes, electrocardiograms, and transthoracic echocardiograms along with 90-day cardiac outcomes were reviewed. All data were reviewed by cardio-oncologists at our institution. RESULTS: Of 37 patients reviewed, mean age was 63 years and 57% were women. 132 procedures were performed with an average of 3.57 procedures per patient. 68.6% of patients had elevated troponin during at least 1 procedure. No patients were found to have acute coronary syndrome, heart failure, unstable arrhythmias, or cardiac death. No patients had notable echocardiographic changes. 10.8% of patients with positive troponin had asymptomatic transient electrocardiographic changes not meeting criteria for myocardial infarction. One patient had non-sustained ventricular tachycardiac intra-operatively which did not recur subsequently. Three patients died from non-cardiac causes within 90-days. There was no oncology treatment interruption, even in those with troponin elevation. In multivariable analysis, a history of hyperlipidemia was a predictor of postoperative troponin elevation. (P = .042). CONCLUSION: Percutaneous Hepatic Perfusion is safe and associated with a transient, asymptomatic troponin elevation peri-operatively without major adverse cardiac events at 90 days. The observed troponin elevation is likely secondary to coronary demand-supply mismatch related to procedural hemodynamic shifts, hypotension, and anemia.

Percutaneous hepatic perfusion using melphalan in patients with uveal melanoma and liver metastases carries no significant cardiac adverse events.

The effect of a single dose of nivolumab prior to isolated limb perfusion for patients with in-transit melanoma metastases: An interim analysis of a phase Ib/II randomized double-blind placebo-controlled trial (NivoILP trial).

OBJECTIVE: ILP has shown to achieve high response rates in patients with melanoma ITM. Possibly there is a synergistic mechanism of action of ILP and anti-PD1. The aim of this trial was to investigate the safety and efficacy of adding a single dose of systemic anti-PD1 to isolated limb perfusion (ILP) for patients with melanoma in-transit metastases (ITM). METHODS: In this placebo controlled double-blind phase Ib/II trial, patients with melanoma ITM were randomized 1:1 to either a single systemic dose of nivolumab or placebo one day prior to ILP. The primary endpoint was complete response (CR) rate at three months, and safety in terms of incidence and severity of adverse events (AEs). RESULTS: A total of 20 patients were included. AEs of any grade occurred in 90% of patients in the nivolumab arm and in 80% in the placebo arm within three months after ILP. Grade 3 AEs were reported in 40% and 30% respectively, most commonly related to wound infection, wound dehiscence, or skin necrosis. There were no grade 4 or 5 AEs reported. The CR rate was 75% in the nivolumab arm and 60% in the placebo arm. The 1-year local progression-free rate was 86% in the nivolumab arm and 67% in the placebo arm. The 1-year OS was 100% in both arms. CONCLUSION: For patients with melanoma ITM, the addition of a single systemic dose of nivolumab the day before ILP is considered safe and feasible with promising efficacy. Accrual will continue in a phase 2 trial.

Feasibility and efficacy of indocyanine green in monitoring systemic drug leakage during isolated limb perfusion for recurrent melanoma of extremity.

Melanoma is known for its high metastatic potential and aggressive growth. Recurrence is common post-surgery, sometimes leading to unresectable disease. Locally recurrent unresectable melanoma of extremity has been treated with high-dose anticancer chemotherapy via isolated limb perfusion (ILP) to improve local efficacy of drug and salvage limbs. Standard ILP monitoring uses radiolabeled dyes, requiring specialized personnel and involving radiation exposure. In this case, we used indocyanine green (ICG) to track systemic drug leakage during ILP. A 47-year-old gentleman with recurrent malignant melanoma of the left foot, operated twice earlier and treated with adjuvant pembrolizumab, presented with multiple in-transit metastases in the limb. ILP was planned, with 5 mg ICG administered in the perfusion solution along with high-dose melphalan. Stryker's SPI PHI handheld device was employed to visualize ICG during ILP. Absence of fluorescence beyond the involved extremity, such as fingers, ears, and the abdominal wall, indicated no systemic drug dispersion. For control, technetium radiocolloid dye was co-administered, monitored by a precordial gamma probe, confirming no systemic leakage, and validating effectiveness of ICG in leakage monitoring. ICG proves to be a safe, reliable, cost-effective, radiation-free approach for precise systemic drug leakage monitoring during ILP for recurrent melanoma of extremity.

Technical considerations for isolated limb perfusion: A consensus paper.

BACKGROUND: Isolated limb perfusion (ILP) is a well-established surgical procedure for the administration of high dose chemotherapy to a limb for the treatment of advanced extremity malignancy. Although the technique of ILP was first described over 60 years ago, ILP is utilised in relatively few specialist centres, co-located with tertiary or quaternary cancer centres. The combination of high dose cytotoxic chemotherapy and the cytokine tumour necrosis factor alpha (TNFα), mandates leakage monitoring to prevent potentially serious systemic toxicity. Since the procedure is performed at relatively few specialist centres, an ILP working group was formed with the aim of producing technical consensus guidelines for the procedure to streamline practice and to provide guidance for new centres commencing the technique. METHODS: Between October 2021 and October 2023 a series of face to face online and hybrid meetings were held in which a modified Delphi process was used to develop a unified consensus document. After each meeting the document was modified and recirculated and then rediscussed at subsequent meeting until a greater than 90% consensus was achieved in all recommendations. RESULTS: The completed consensus document comprised 23 topics in which greater than 90% consensus was achieved, with 83% of recommendations having 100% consensus across all members of the working group. The consensus recommendations covered all areas of the surgical procedure including pre-operative assessment, drug dosing and administration, perfusion parameters, hyperthermia, leakage monitoring and theatre logistics, practical surgical strategies and also post-operative care, response evaluation and staff training. CONCLUSION: We present the first joint expert-based consensus statement with respect to the technical aspects of ILP that can serve as a reference point for both existing and new centres in providing ILP.

[Contribution of intraperitoneal chemotherapy in the treatment of colorectal peritoneal carcinoma. HIPEC, PIPAC, state of the art and future directions]. / La chimiothérapie intra-péritonéale dans le traitement de la carcinose péritonéale d'origine colorectale. CHIP, PIPAC, état des lieux et perspectives.

After more than a decade of good results using the combination of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of peritoneal carcinosis of colorectal origin, the PRODIGE7 study, which specifically evaluated the role of HIPEC, failed to show any superiority in terms of overall and disease-free survival for the CRS+HIPEC combination compared with CRS alone. This study constituted a radical change in the knowledge and therapeutic attitudes observed to date. After reviewing the literature and the consensus of national and international experts, a synthesis is provided, together with an outlook on the questions raised and the therapeutic trials and innovations of the near future. An analysis of recent advances due to the advent of a new technique, PIPAC, is also proposed, as well as a review of current therapeutic trials in this field.

The impact of the extent of surgery on late adverse effects following cytoreductive surgery and HIPEC.

AIM: To investigate the impact of the surgical extent on late adverse effects (LAE) following cytoreductive surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC). METHOD: A prospective cohort study including patients undergoing CRS + HIPEC due to peritoneal metastases from gastrointestinal tumour origin. From 2006 through 2019, consecutive patients treated with CRS + HIPEC were followed at 3, 6 and 12 months, and LAEs were assessed using the symptom scales and items from the European Organization for Research and Treatment of Cancer QLQ-C30 (EORTC QLQ-C30). Surgical extent was categorized into three groups (major, intermediate, minor) based on peritonectomy procedures and colorectal resections performed as part of CRS. EORTC data were analysed using a linear mixed effects regression model adjusted for age, gender, origin of tumour and comorbidity. RESULTS: In total, 257 patients who responded to at least one questionnaire during the follow-ups were included. Only diarrhoea symptoms were positively associated with surgical extent (mean differences: major vs. minor: 8.4 (-0.5; 17.2) (p = 0.06) and major vs. intermediate: 10.9 (3.8; 18.0) (p = 0.00)). Additionally, diarrhoea symptoms persisted throughout the study period and did not change over time (mean difference 12-3 months: -3.6 (-9.1; 1.7) (p-value = 0.18)). Overall, the levels of different symptom scales (fatigue, nausea and vomiting, pain, dyspnoea, and appetite loss) significantly decreased from 3 to 12 months. CONCLUSION: Patients undergoing extensive CRS suffer from persistent impaired gastrointestinal function in terms of diarrhoea compared patients undergoing to less extensive surgery. Attention should be directed at detecting such LAE and to guide patients accordingly.

Application of HIPEC simulations for optimizing treatment delivery strategies.

INTRODUCTION: Hyperthermic IntraPEritoneal Chemotherapy (HIPEC) aims to treat microscopic disease left after CytoReductive Surgery (CRS). Thermal enhancement depends on the temperatures achieved. Since the location of microscopic disease is unknown, a homogeneous treatment is required to completely eradicate the disease while limiting side effects. To ensure homogeneous delivery, treatment planning software has been developed. This study compares simulation results with clinical data and evaluates the impact of nine treatment strategies on thermal and drug distributions. METHODS: For comparison with clinical data, three treatment strategies were simulated with different flow rates (1600-1800mL/min) and inflow temperatures (41.6-43.6 °C). Six additional treatment strategies were simulated, varying the number of inflow catheters, flow direction, and using step-up and step-down heating strategies. Thermal homogeneity and the risk of thermal injury were evaluated. RESULTS: Simulated temperature distributions, core body temperatures, and systemic chemotherapeutic concentrations compared well with literature values. Treatment strategy was found to have a strong influence on the distributions. Additional inflow catheters could improve thermal distributions, provided flow rates are kept sufficiently high (>500 mL/min) for each catheter. High flow rates (1800 mL/min) combined with high inflow temperatures (43.6 °C) could lead to thermal damage, with CEM4310 values of up to 27 min. Step-up and step-down heating strategies allow for high temperatures with reduced risk of thermal damage. CONCLUSION: The planning software provides valuable insight into the effects of different treatment strategies on peritoneal distributions. These strategies are designed to provide homogeneous treatment delivery while limiting thermal injury to normal tissue, thereby optimizing the effectiveness of HIPEC.

Variation in response rates to isolated limb perfusion in different soft-tissue tumour subtypes: an international multi-centre study.

OBJECTIVE: The aim of this study was to investigate the response rates of different extremity soft-tissue sarcoma subtypes (eSTS) after isolated limb perfusion (ILP), based on an international multi-centre study. MATERIALS AND METHODS: The retrospective cohort comprised eSTS patients from 17 specialised ILP centres that underwent melphalan-based ILP, with or without recombinant human tumour necrosis factor (rhTNFα) (TM-ILP and M-ILP, respectively). Response was measured on imaging (magnetic resonance imaging) and/or clinical response, for which M-ILPs were excluded. RESULTS: A total of 1109 eSTS patients were included. The three most common histological subtypes were undifferentiated pleomorphic sarcoma (17%, n = 184), synovial sarcoma (16%, n = 175) and myxofibrosarcoma (8%, n = 87). rhTNFα was used in 93% (TM-ILP) and resulted in a significantly better overall response rate (ORR, p = 0.031) and complete responses (CR, p < 0.001) in comparison to M-ILP, without significant differences among histological subgroups. The ORR of TM-ILP was 68%, including 17% CR. Also, 80% showed progressive disease. Significantly higher response rates were shown for Kaposi sarcoma (KS) with 42% CR and 96% ORR (both p < 0.001), and significantly higher CR rates for angiosarcoma (AS, 45%, p < 0.001) and clear cell sarcoma (CCS, 31%, p = 0.049). ILP was followed by resection ≤ 6 months in 80% of the patients. The overall limb salvage rate was 88%, without significant differences among histological subgroups, but was significantly higher for ILP responders compared to non-responders (93% versus 76%, p < 0.001). CONCLUSION: ILP resulted in high response and LRS among all eSTS subtypes, however, with significant differences between subtypes with most promising results for KS, AS and CCS.

[Isolated liver perfusion with melphalan followed by pembrolizumab therapy for unresectable metastases of uveal melanoma to the liver]. / Sposob izolirovannoi perfuzii pecheni melfalanom s posleduyushchei terapiei pembrolizumabom v lechenii nerezektabel'nykh metastazov uveal'noi melanomy, ogranichennykh pechen'yu.

Uveal melanoma accounts for 80% of all ocular melanomas, and 30-60% of patients have metastases to the liver. A few patients are candidates for liver resection, and this disease is associated with poor prognosis. There are few data on optimal management of metastatic uveal melanoma. Isolated hepatic perfusion is a perspective method for regional treatment of inoperable metastatic liver lesions with uveal melanoma. We present a patient with uveal melanoma who underwent previous enucleation of the eye. Cancer progressed 15 years later as an isolated inoperable metastatic liver lesion. The patient underwent isolated liver perfusion with melphalan, hyperthermia and oxygenation. Subsequently, the patient received systemic therapy with pembrolizumab. Partial response was achieved 1 month after the procedure. There was no progression for 20 months after surgery under systemic therapy with pembrolizumab. Thus, isolated liver chemoperfusion with melphalan is advisable in these patients.

[Preoperative Prognostic Factors in CRS plus HIPEC for Patients with Peritoneal Dissemination of Colorectal Cancer].

Peritoneal dissemination of colorectal cancer has the poorest prognosis among metastatic sites, with an average overall survival of less than 6 months. Various treatment methods have been reported for these patients, and recently there have been several reports showing the usefulness of cytoreductive surgery(CRS)combined with hyperthermic intraperitoneal chemotherapy (HIPEC). However, the studies on this treatment are limited. In this study, we retrospectively reviewed cases of CRS plus HIPEC. Twenty-one patients who underwent CRS plus HIPEC at Tokyo Medical University Hospital and Toda Central General Hospital between August 2014 and December 2017 were included in this study. The long-term and short-term survival groups were analyzed separately, and predictors of preoperative treatment efficacy were examined. The surgical approach was open in 16 cases and laparoscopic in 5 cases. Complete resection was achieved in 10 of these patients. Postoperative complications occurred in 6 patients. There were no deaths within 90 days of surgery. The median overall survival was 17.0 months, and the 1-year survival rate was 65%. Median progression-free survival was 11.0 months. In a multivariate analysis predicting long-term versus short-term survival groups, sex, primary tumor location, and P factor were independent predictors of treatment response. CRS plus HIPEC therapy is considered an effective treatment option. The predictors of preoperative treatment response include sex, primary tumor location, and P factor.

Isolated Hepatic Perfusion With Melphalan for Patients With Isolated Uveal Melanoma Liver Metastases: A Multicenter, Randomized, Open-Label, Phase III Trial (the SCANDIUM Trial).

PURPOSE: About half of patients with metastatic uveal melanoma present with isolated liver metastasis, in whom the median survival is 6-12 months. The few systemic treatment options available only moderately prolong survival. Isolated hepatic perfusion (IHP) with melphalan is a regional treatment option, but prospective efficacy and safety data are lacking. METHODS: In this multicenter, randomized, open-label, phase III trial, patients with previously untreated isolated liver metastases from uveal melanoma were randomly assigned to receive a one-time treatment with IHP with melphalan or best alternative care (control group). The primary end point was overall survival at 24 months. Here, we report the secondary outcomes of response according to RECIST 1.1 criteria, progression-free survival (PFS), hepatic PFS (hPFS), and safety. RESULTS: Ninety-three patients were randomly assigned, and 87 patients were assigned to either IHP (n = 43) or a control group receiving the investigator's choice of treatment (n = 44). In the control group, 49% received chemotherapy, 39% immune checkpoint inhibitors, and 9% locoregional treatment other than IHP. In an intention-to-treat analysis, the overall response rates (ORRs) were 40% versus 4.5% in the IHP and control groups, respectively (P < .0001). The median PFS was 7.4 months versus 3.3 months (P < .0001), with a hazard ratio of 0.21 (95% CI, 0.12 to 0.36), and the median hPFS was 9.1 months versus 3.3 months (P < .0001), both favoring the IHP arm. There were 11 treatment-related serious adverse events in the IHP group compared with seven in the control group. There was one treatment-related death in the IHP group. CONCLUSION: IHP treatment resulted in superior ORR, hPFS, and PFS compared with best alternative care in previously untreated patients with isolated liver metastases from primary uveal melanoma.

Chemosaturation for primary and secondary liver malignancies: A comprehensive update of current evidence.

Regional therapies for primary and secondary liver tumors have garnered interest in recent years and several types of treatment approaches have been pursued to control disease, palliate symptoms, and extend survival. Chemosaturation is an innovative way to deliver high-dose chemotherapy to the liver via the hepatic artery. Within the last decade, "isolated hepatic perfusion" (IHP) has evolved from an open surgical approach to a minimally invasive procedure, now termed "chemosaturation" (CS) with "percutaneous hepatic perfusion (PHP)". The most conclusive data on CS-PHP is currently available for patients with hepatic metastases from uveal melanoma (UM) - a rare but devastating disease with a poor long-term survival rate. A global phase-3 study and several cohort studies have provided compelling evidence that CS-PHP is an effective salvage treatment for liver-dominant metastatic UM in institutions with appropriate expertise. In this review we provide an overview on the technique, available clinical data, including safety and efficacy, and potential indications for CS-PHP.

New perspectives in unresectable cholangiocarcinoma? Evaluation of chemosaturation with percutaneous hepatic perfusion as a palliative treatment option.

Cholangiocarcinoma (CCA) are the second most common primary liver tumors and carry a dismal prognosis. Chemosaturation with percutaneous hepatic perfusion (PHP) is a palliative, intra-arterial therapeutic approach that provides a high dose chemotherapy of the liver with reduced systemic exposure. Aim of this retrospective, monocentric study was to analyze PHP as a palliative treatment for unresectable CCA. Toxicity, adverse events and complications were classified using the Common Terminology Criteria for Adverse Events (CTCAE v5.0). Overall response rate (ORR) and disease control rate (DCR) were evaluated according to the Response Evaluation Criteria in Solid Tumors (RECIST1.1). Median overall survival (mOS), median progression-free survival (mPFS) and hepatic mPFS (mhPFS) were computed using Kaplan-Meier estimation. In total 17 patients were treated with 42 PHP between 10/2014 and 09/2020. No significant complications occurred during the interventions. mOS was 27.6 (interquartile range (IQR) 16.5-37) months from first diagnosis and 9.9 (IQR 3.8-21) months from first PHP. mPFS was 4 (IQR 2-7) and mhPFS was 4 (IQR 3-10) months. ORR was 25% and DCR 75%. Significant, but transient hematotoxicity was frequent with grade 3/4 thrombopenia after 50%, leukopenia after 26% and anaemia after 21% of the interventions. An increase of transaminases (AST increase after 21% and ALT increase after 14% of the PHP) developed more often than a deterioration of the liver synthesis capacity. Salvage treatment with PHP has the potential to prolong life in selected patients with unresectable, refractory cholangiocarcinoma. The interventional procedure is safe. Post-interventional toxicity is frequent but manageable.

Depression, Anxiety, Stress and Distress Following Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: Results of a Prospective Cohort Study.

The aim of this study was to describe the levels of depression, anxiety, stress, and distress in patients undergoing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The 21-item Depression, Anxiety and Stress Scale (DASS-21) and Distress Thermometer were administered preoperatively, postoperatively day 10, and at hospital discharge to 169 patients with peritoneal carcinomatosis undergoing CRS and HIPEC. The mean preoperative values for DASS-21 subscale scores were 4.7 (depression), 4.2 (anxiety), and 8.4 (stress), and the mean preoperative Distress Thermometer rating was 4.0. No significant changes in levels of depression, stress, or distress were noted thereafter. The DASS-21 anxiety subscale score significantly increased at hospital discharge (p = .005). Higher levels of preoperative psychological depression, anxiety, stress and distress were associated with worse mental component scores. Higher preoperative depression levels were associated with the provision of more clinical psychologist occasions of service, and higher preoperative distress levels were associated with younger age. Preoperative psychological measures are important for ensuring CRS and HIPEC patients that require additional support are identified and provided with ongoing psychological interventions.

Chemosaturation of the Liver - an Update. / Chemosaturation der Leber ­ ein Update.

BACKGROUND: Percutaneous hepatic perfusion (CS-PHP) is a treatment option for primary and secondary liver neoplasms and subject of intensive research. This present article provides an overview of CS-PHP regarding patient safety, feasibility and effectiveness based on recent studies. METHOD: We performed a PubMed search including the search terms chemosaturation, hepatic chemosaturation, percutaneous perfusion and melphalan. RESULTS AND CONCLUSION: CS-PHP is a promising procedure for the treatment of uveal melanoma and cholangiocellular carcinoma. There are insufficient data regarding the effectiveness of CS-PHP with respect to other tumor entities. Since CS-PHP can be accompanied by multiple transient side effects and complications, close interdisciplinary cooperation is necessary. KEY POINTS: · Chemosaturation of the liver is a safe procedure.. · CS-PHP is a potent therapy for hepatic metastatic ocular melanoma and cholangiocellular carcinoma.. · The procedure requires close interdisciplinary coordination.. · CS-PHP is a repeatable and thus long-term therapeutic option for some patients..
