- Primary Outcome Measures
Name Time Method Disease free survival Through study completion, an average of 3 years Prospective analysis of disease free after CRS/HIPEC for peritoneal carcinomatosis
Overall survival Through study completion, an average of 3 years Prospective analysis of overall survival after CRS/HIPEC for peritoneal carcinomatosis
- Secondary Outcome Measures
Name Time Method Renal function (serum creatinine (mg/dl)) Before as well as during the first 7 days postoperative Screening for acute renal insufficiency by measuring serum chemistry (serum creatinine (mg/dl) before as well as during the first 7 postoperative days
Renal function (urine output (ml/24h)) Before as well as during the first 7 days postoperative Screening for acute renal insufficiency by measuring urine output (ml/24h) before as well as during the first 7 postoperative days
Microbiome (Bacterial 16S ribosomal RNA gene sequences will be amplified, sequenced, and analyzed in comparison to publicly available data obtained from healthy volunteers) Before as well as at postoperative day 2 and 7 Longitudinal analysis of the microbial burden within samples will be quantified with droplet digital polymerase chain reaction. Bacterial 16S ribosomal RNA gene sequences will be amplified, sequenced, and analyzed in comparison to publicly available data obtained from healthy volunteers.
Renal function (urea (mg/dl)) Before as well as during the first 7 days postoperative Screening for acute renal insufficiency by measuring serum chemistry (serum urea (mg/dl) before as well as during the first 7 days postoperative
Quality of life (Questionnaire-WHOQOL-BREF) Before surgery and through study completion, an average of 3 years Prospective analysis of quality of life after CRS/HIPEC for peritoneal carcinomatosis. Questionnaire-WHOQOL-BRE produces a quality of life profile. It is possible to derive four domain scores. There are also two items that are examined separately: question 1 asks about an individual's overall perception of quality of life and question 2 asks about an individual's overall perception of their health. The four domain scores denote an individual's perception of quality of life in each particular domain (Physical health (Score 7-35), Psychological (Score 6-30), Social relationships (Score 3-15), Environment (Score 8-40)). Domain scores are scaled in a positive direction (i.e. higher scores denote higher quality of life). The mean score of items within each domain is used to calculate the domain score transformed to 4-20 or 20-100.
Cellular immune response (Frequency of NK cell subpopulations within lymphocyte populations measured by flow cytometry) Before as well as at postoperative day 2 and 7 Longitudinal analysis of cellular immune responses in blood and peritoneal tissue by flow cytometry. Measuring frequency of NK cell populations within total lymphocyte population
