Microbiome (Bacterial 16S ribosomal RNA gene sequences will be amplified, sequenced, and analyzed in comparison to publicly available data obtained from healthy volunteers)
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.

Time frame: Before as well as at postoperative day 2 and 7
Cellular immune response (Frequency of NK cell subpopulations within lymphocyte populations measured by flow cytometry)
Longitudinal analysis of cellular immune responses in blood and peritoneal tissue by flow cytometry. Measuring frequency of NK cell populations within total lymphocyte population
Time frame: Before as well as at postoperative day 2 and 7
Quality of life (Questionnaire-WHOQOL-BREF)
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.
Time frame: Before surgery and through study completion, an average of 3 years
