Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) as an outpatient procedure.

ABSTRACT: Background:Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) is a drug-delivery method for patients with peritoneal metastasis (PM). The study objective was to investigate whether PIPAC is possible in an outpatient setting. Methods:Data was extracted from the prospective PIPAC-OPC2 study (ClinicalTrials.gov NCT03287375). Patients with PM were treated by cisplatin and doxorubicin (PIPAC C/D), except patients with colorectal PM, who were treated by oxaliplatin (PIPAC OX). Patients were evaluated concerning the suitability for carrying out the PIPAC procedure in an out- patient setting. The preconditions for outpatient surgery were that the patient should be (1) freely mobilized, (2) adequately pain-relieved, (3) have untroubled urination and (4) without anxiety or discomfort caused by leaving the hospital. Results:During the study period, 106 PIPAC procedures (79 PIPAC C/D, 27 PIPAC OX) were performed in 41 patients with gastrointestinal or ovarian PM. Ninety percent (37/41) of the patients were pretreated with systemic chemotherapy. Eight patients (20%) received bidirectional chemotherapy. Twenty-four percent (10/41) of the first PIPAC procedures were completed in an outpatient setting, which increased to 65% (13/20) in PIPAC no 3 (p=0.008). In the PIPAC C/D cohort, 28% and 80% of the PIPACs were performed in the outpatient setting at PIPAC 1 and 3 respectively, contrasting to only 11% and 20% in the PIPAC OX group. No readmissions after outpatient care. Postoperative morphine administration was more frequent in the PIPAC OX group. Conclusions:The PIPAC procedure can be performed in an outpatient setting. The critical component for success is pain control.

Project description:BackgroundPatients with recurrent malignant epithelioid mesothelioma (MM) after surgery and standard chemotherapy with cisplatin and pemetrexed have limited treatment options.MethodsWe performed a retrospective cohort study of patients with recurrent MM undergoing Pressurized IntraPeritoneal/Thoracal Aerosol Chemotherapy (PIPAC/PITAC) with doxorubicin 1.5 mg/m2 and cisplatin 7.5 mg/m2. Data were retrospectively collected in a prospective registry of patients undergoing PIPAC/PITAC. Study outcomes were microscopic tumor regression grade (TRG), survival and adverse events (v4.0 CTCAE).ResultsA total of 29 patients (m/f = 17/12) with MM with a mean age of 62.4 (range: 42 to 84) years were analyzed. A total of 74 PIPAC and 5 PITAC procedures were performed. The mean number of PIPAC applications was 2.5 (range: 0 to 10) per patient. Twenty patients (69%) had > 2 PIPAC procedure and were eligible for TRG analysis. TRG 1 to 4 was observed in 75% (15/20) of patients. Major regression (TRG 3) or complete regression (TRG 4) was observed in 20% and 10%, respectively. PIPAC induced significant tumor regression in 51.7% (15/29) of patients with a cumulative effect after repetitive PIPACs (PIPAC #1 vs. PIPAC #2: p = 0.001; PIPAC #1 vs. PIPAC #3: p = 0.001; PIPAC #1 vs. PIPAC #4: p = 0.001). Postoperative CTCAE grade 4 complications were observed in two patients (6.9%) who had cytoreductive surgery (CC2) and intraoperative PIPAC. One patient (3.4%) died due to postoperative kidney insufficiency. After a follow up of 14.4 (95% CI: 8.1 to 20.7) months after the last PIPAC/PITAC application, median overall survival was 26.6 (95% CI: 9.5 to 43.7) months (from the first application).ConclusionAfter prior abdominal surgery and systemic chemotherapy, repetitive PIPAC applications are feasible and safe for patients with end-stage MM. Furthermore, PIPAC induces significant histological regression of malignant mesothelioma in the majority of patients. PITAC is feasible, but its safety and efficacy to control malignant pleural effusion remain unclear.

Project description:BackgroundPeritoneal carcinomatosis (PC) is a common endpoint in both gastrointestinal and non-gastrointestinal cancers, and PC is treated as other systemic metastases - unfortunately with disappointing results and considerable side-effects. Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) is a new method of applying traditional chemotherapy, and preliminary data indicate that PIPAC is safe, able to stabilize or improve quality of life, and can induce an objectively measurable reduction in disease burden in PC.MethodsPIPAC-OPC2 is a prospectively controlled Phase II, single center, one-arm, open-label clinical trial investigating the treatment effect of PIPAC in patients with histological or cytological proven PC from gastrointestinal, ovarian or primary peritoneal cancer. Eligible patients will receive PIPAC in series of three using a combination of doxorubicin (1.5 mg/m2) and cisplatin (7.5 mg/m2) for non-colorectal cancer patients (PIPAC C/D), and oxaliplatin (92 mg/m2) in patients with PC of colorectal origin (PIPAC OX). Patients are monitored by: (1) repeated measurements of the Peritoneal Regression Grading Score (PRGS) in biopsies obtained from metal clips marked areas, (2) Quality-of-Life (QoL) questionnaires, (3) Magnetic Resonance Imaging (MRI) and (4) Prognostic Nutritional Index (PNI). Adverse events and surgical complications will be recorded according to the 30 days definition.ResultsThe primary outcome of PIPAC-OPC2 is to evaluate if PIPAC can induce major or complete response (PRGS 1 or 2) within a series of three PIPAC procedures. Secondarily this study investigates changes in QoL and MRI as a staging and response evaluation tool. The secondary outcomes will be used to create a model that may predict which of the patients will benefit from PIPAC treatment.ConclusionsIt is expected that PIPAC directed therapy can induce major or complete response in 50 % of patients with PC of colorectal origin and in 30 % of patients with PC of non-colorectal origin - and at the same time stabilize or even improve quality of life. This trial may provide data regarding the utility of MRI as a staging and response evaluation tool in patients with PC.Trial registrationThe study is registered with ClinicalTrials.gov Identifier NCT03287375 and the European Clinical Trials Database (EudraCT) number 2016-003394-18.

Project description:Objective: The objective of this study is to analyze oncological outcomes of patients with peritoneal metastases (PM) of colorectal origin treated with Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC). Background: PIPAC has been demonstrated to be a feasible and safe novel treatment for patients with PM of various origins. Only small series reports on survival after PIPAC by disease entity. Methods: International retrospective cohort study of consecutive patients with PM of colorectal origin. Outcome measures were overall survival (OS), radiological response according to Response Evaluation Criteria in Solid Tumors (RECIST), histological response (peritoneal regression grading score [PRGS]: complete response: 1–4: no response), change of peritoneal cancer index (PCI), and symptom control. Results: Seventeen eligible centers compiled 256 non-selected patients (mean age 61 [50.6–69.2], 43% female) and 606 procedures. Sixty-three percent were treated after 2 lines of chemotherapy, median PCI at PIPAC1 was 18 (interquartile range [IQR] = 10–27). Median OS was 19.00 months (IQR = 12.9–29.8) from diagnosis and 9.4 months (IQR = 4.5–16.8) from PIPAC1. One hundred and four of 256 patients (40.6%) had ≥3 procedures (per protocol [pp]) with the following outcomes at PIPAC3: RECIST: 59.3% partial response/stable, 40.7% progression; mean PRGS: 2.1 ± 0.9. Median PCI was 21 (IQR = 15–29) at baseline and 20 (IQR = 12–27) at PIPAC3 (P = 0.02). Fifty-six (54%) and 48 (46%) patients were symptomatic at baseline and PIPAC3, respectively (P = 0.267). Median OS for the pp cohort was 11.9 months (IQR = 10.7–15.0) from PIPAC1. Independent predictors for survival were radiological response (HR = 3.0; 95% CI = 1.6–5.7) and no symptoms (HR = 4.5, 95% CI = 2.2–9.1) at PIPAC3. Conclusions: Objective treatment response and encouraging survival were demonstrated after PIPAC for colorectal PM. Prospective registry data and comparative studies are now needed in to confirm these data.

Project description:BackgroundPressurized intraperitoneal aerosol chemotherapy (PIPAC) is a novel intraperitoneal drug delivery method of low-dose chemotherapy as a pressurized aerosol in patients affected by peritoneal cancer of primary or secondary origin. We performed a systematic review and meta-analysis with the aim of assessing the feasibility, safety, and efficacy of PIPAC.MethodsA systematic literature search was performed using Medline and Web of Science databases from 1 January 2011, to inception, to 31 December 2021. Data were independently extracted by two authors. The Newcastle-Ottawa Scale was used to assess the quality and risk of bias of studies. Meta-analysis was performed for pathological response, radiological response, PCI variation along treatment, and for patients undergoing three or more PIPAC. Pooled analyses were performed using the Freeman-Tukey double arcsine transformation, and 95% CIs were calculated using Clopper-Pearson exact CIs in all instances.ResultsA total of 414 papers on PIPAC were identified, and 53 studies considering 4719 PIPAC procedure in 1990 patients were included for analysis. The non-access rate or inability to perform PIPAC pooled rate was 4% of the procedures performed. The overall proportion of patients who completed 3 or more cycles of PIPAC was 39%. Severe toxicities considering CTCAE 3-4 were 4% (0% to 38.5%). In total, 50 studies evaluated deaths within the first 30 postoperative days. In the included 1936 patients were registered 26 deaths (1.3%). The pooled analysis of all the studies reporting a pathological response was 68% (95% CI 0.61-0.73), with an acceptable heterogeneity (I2 28.41%, p = 0.09). In total, 10 papers reported data regarding the radiological response, with high heterogeneity and a weighted means of 15% (0% to 77.8%). PCI variation along PIPAC cycles were reported in 14 studies. PCI diminished, increased, or remained stable in eight, one and five studies, respectively, with high heterogeneity at pooled analysis. Regarding survival, there was high heterogeneity. The 12-month estimated survival from first PIPAC for colorectal cancer, gastric cancer, gynecological cancer and hepatobiliary/pancreatic cancer were, respectively, 53%, 25%, 59% and 37%.ConclusionsPIPAC may be a useful treatment option for selected patients with PM, with acceptable grade 3 and 4 toxicity and promising survival benefit. Meta-analysis showed high heterogeneity of data among up-to-date available studies. In a subset analysis per primary tumor origin, pathological tumor regression was documented in 68% of the studies with acceptable heterogeneity. Pathological regression seems, therefore, a reliable outcome for PIPAC activity and a potential surrogate endpoint of treatment response. We recommend uniform selection criteria for patients entering a PIPAC program and highlight the urgent need to standardize items for PIPAC reports and datasets.
