Background; Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is associated with improved survival for patients with abdominal malignancies with peritoneal dissemination .This study aimed to evaluate the effect of Education program on improving patient reported recovery profile post Hyperthermia Intraperitoneal Chemotherapy for Peritoneal Carcinomatosis .Design: Quasi-experimental design was utilized in this study . Setting :The study was carried out at intensive care unit at the National Cancer Institute (NCI), Cairo University. During the period from the beginning of January 2019 till the beginning of January 2020 Sample :Purposive sample of 97 patients Tools :Two tools used to collect the study data .These are structured interview questionnaire to assess patients' knowledge regarding Hyperthermia Intraperitoneal Chemotherapy, and Patient-Reported Recovery Profile Results : Showed that there was statistically significant difference in term of increased knowledge level among study group , as well as a increase in total mean score in patient-reported recovery Profile pre ,immediately and after education program implementation ,shows high statistically significant negative correlation between of length of hospital stay and reported recovery profile immediately post and after program implementation inverse relationship. Conclusion :Implementing a designed education program for patients with Hyperthermia Intraperitoneal Chemotherapy was effective in improving knowledge, and patient-reported recovery. Shows high statistically significant negative correlation between length of hospital stay and reported recovery profile immediately post and after program implementation. Recommendation :additional demographic variables. Manuals, information booklets and self-instruction module should be developed in areas of Hyperthermia Intraperitoneal Chemotherapy management
