  • Title: Peritoneal Surface Disease Severity Score as a predictor of resectability in the treatment of peritoneal surface malignancies.
    Author: Yoon W, Alame A, Berri R.
    Journal: Am J Surg; 2014 Mar; 207(3):403-7; discussion 406-7. PubMed ID: 24444858.
    Abstract:
    BACKGROUND: We evaluated the clinical utility of the Peritoneal Surface Disease Severity Score (PSDSS) as a preoperative predictor of resectability in the treatment of peritoneal surface malignancies. METHODS: Forty-nine patients were selected for cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) and were stratified according to the PSDSS retrospectively. RESULTS: Of 52 cytoreductive surgeries performed in 49 patients, HIPEC was performed in 33 cases (63%). We analyzed 31 cases of appendiceal and colorectal cancer patients who underwent CRS and HIPEC and 12 who underwent CRS only. 68% of the patients in whom CRS and HIPEC was performed were classified as PSDSS stage I or II. Contrastingly, all patients in whom CRS and HIPEC was unachievable were scored as PSDSS stage III or IV. CONCLUSIONS: The outcomes of this study suggest that the PSDSS can be used as a preoperative assessment tool to predict disease resectability in the treatment of peritoneal surface malignancies.
