CANCER, DISEASE COURSE
All data including demographic, clinico-pathological, oncological, intraoperative, and perioperative parameters were prospectively recorded and retrospectively analyzed.We relied on our patient registry for follow-up, if the given patient stayed with us in treatment or died in our hospital. We also utilized our local cancer registry, whenever patients resided within the administrative district of Leipzig. For additional information about the disease course and survival data, we contacted each patient’s physician (e.g., general practitioner or oncologist).Values are presented as number and percent, mean with standard error of the mean (SEM), or median with (interquartile) range. Whenever measurements were taken for each PIPAC procedure (e.g., body mass index), the mean or median for each patient was calculated first. The overall mean or median was determined by starting from this now independent sample. SEM and (interquartile) range were also calculated from the latter sample. Data evaluations and statistical analyzes were carried out using Excel (Version 2105; Microsoft Corp., Redmond, WA, USA) and SPSS (Version 27.0; IBM Corp., Armonk, NY, USA). Figures were created using Excel and PowerPoint (Version 2105; Microsoft Corp., Redmond, WA, USA).
