Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The number of patients with major toxicity (grade *3 according to the Common Terminology Criteria for Adverse Events v4.0) up to four weeks after the last procedure. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcomes are: * the environmental safety of ePIPAC-OX, based on air concentrations (measured by RPS Analyse, Breda, Netherlands) and surface concentrations (measured by Pharmacy, Cathari-na Hospital, Eindhoven, Netherlands) of oxaliplatin during the first three procedures, measured by atomic absorption spectrophotometry; * procedure-related characteristics of ePIPAC-OX (e.g. laparoscopic access, intraoperative complications, amount of adhesions, technical difficulties, operating time); * the number of procedures in each patient and reasons for discontinuation; * minor toxicity, defined as grade *2 according to CTCAE v4.0 [120], up to four weeks after the last ePIPAC-OX; * organ-specific toxicity, based on bone marrow, liver, and kidney functions measured at dif-ferent time points (Table 1); * major and minor postoperative complications, defined as grade *3 and grade *2 according to Clavien-Dindo [121], respectively, up to four weeks after the last ePIPAC-OX; * hospital stay, defined as the number of days between ePIPAC-OX and initial discharge; * readmissions, defined as any hospital admission after initial discharge, up to four weeks af-ter the last ePIPAC-OX; * radiological tumour response, based on central review of thoracoabdominal CT and DW-MRI at baseline and four weeks after each ePIPAC-OX, performed by two independent ra-diologists (JN, MLH) blinded to clinical outcomes (classification is not defined a priori); * histopathological tumour response, based on central review of collected peritoneal biop-sies during each ePIPAC-OX, performed by two independent pathologists (e.g. CJRH) blind-ed to clinical outcomes by using the Peritoneal Regression Grading Score [122]; * cytological tumour response, based on collected ascites or peritoneal washing cytology dur-ing each ePIPAC-OX; * macroscopic tumour response, based on PCI and ascites volume during each ePIPAC-OX; * biochemical tumour response, based on tumour markers mea | — |
