Implementation of the enhanced recovery after surgery protocol for patients with peritoneal carcinomatosis undergoing cytoreductive surgery and hyperthermic intraperitoneal chemoperfusion.

AIM OF THE STUDY: To investigate the feasibility of enhanced recovery after surgery (ERAS) protocol for patients with primary peritoneal carcinomatosis (PC) undergoing cytoreductive surgery with hyperthermic intraperitoneal chemoperfusion (HIPEC) based on the length of hospital stay (LOS), return of bowel function, the incidence of postoperative complications, and quality of life (QLQ) analysis. MATERIAL AND METHODS: The study included a total of 37 patients with primary PC of different origin, who underwent cytoreductive surgery plus HIPEC. Patients were divided into 2 groups: Group I (nonERAS) - 20 patients and Group II (ERAS) - 17 patients. RESULTS: The median LOS in Group I (nonERAS) (12.35 ± 3.9) was longer than in Group II (ERAS) (6.8 ± 1.9) (p < 0.01). The use of the ERAS protocol significantly contributed to the faster return of bowel function (peristalsis and stool) in the postoperative period (p < 0.01). There was no statistically significant difference in the incidence of postoperative complications between the ERAS and nonERAS groups, which supports its clinical safety. Improved QLQ according to the obtained data has also been achieved due to the introduction of the principles of the ERAS protocol. CONCLUSIONS: The obtained results prove the expediency and feasibility of the implementation of the ERAS protocol among patients undergoing cytoreductive surgery in combination with HIPEC.

The impact of hyperthermic intraperitoneal chemotherapy and cytoreductive surgery on clinical outcomes and quality of life of patients with peritoneal carcinomatosis.

AIM OF THE STUDY: To investigate the impact of hyperthermic intraperitoneal chemotherapy (HIPEC) on the clinical and oncological outcomes and quality of life (QOL) of patients with peritoneal carcinomatosis (PC). MATERIAL AND METHODS: The study involved 304 patients with PC of different origin, who were divided into 2 groups: Group I - cytoreductive surgery (CRS) + adjuvant chemotherapy (ACT) - 247 patients; Group II - CRS + HIPEC + ACT - 57 patients. Intraoperative characteristics and postoperative complications were compared. Patients' QOL was assessed at all phases of treatment using the international scales the Short Form-36 Health Survey (SF-36) and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire for Breast Cancer Core 30 (EORTC QLQ-C30). RESULTS: No statistically significant differences were observed between the 2 groups comparing the average blood loss and the total rate of postoperative complications, although the rates of hyperthermia and acute renal failure in the early postoperative period were higher in the HIPEC group. The use of HIPEC significantly contributed to the worse restoration of intestinal function in the postoperative period and to prolonged hospital stay. Assessment of the QOL of patients in Group II using SF-36 showed no significant difference between the physical and psychological components of health compared with the control group. The analysis of EORTC data showed a significant deterioration in the QOL of patients in Group II due to increased scales of pain, nausea and vomiting, and constipation in the early postoperative period. No difference in QOL was observed in the subsequent phases of treatment and after its completion. Overall survival and disease-free survival of patients with ovarian cancer who underwent HIPEC were significantly better compared with CRS + ACT alone. CONCLUSIONS: The proposed HIPEC technique has demonstrated its clinical safety in the treatment of PC, no long-term negative impact on the QOL of patients, and better oncological results for ovarian cancer.
