ABSTRACT We analyzed the feasibility of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in patients with pseudomyxoma peritonei.
A prospective database comprised 90 consecutive patients with demonstrable pseudomyxoma peritonei collected during 48 months. These patients, referred to our unit for consideration for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy, received both cytoreductive surgery and hyperthermic intraperitoneal chemotherapy if possible. We evaluated the factors associated with a successful procedure.
Hyperthermic intraperitoneal chemotherapy was successfully delivered to 56 of 90 patients (62%) with demonstrable pseudomyxoma peritonei. Tumor morphology of low grade (p = 0.013), age under 65 years (p = 0.004), and serum carcinoembryonic antigen level under 5.0 µg/L (p = 0.003) were associated with successful administration of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. Mean peritoneal cancer index was lower (18.9 vs 32.6, p < 0.001) and age was younger (54.3 vs 61.6, p = 0.003) in patients who underwent hyperthermic intraperitoneal chemotherapy than in patients who did not. Four patients had complete cytoreductive surgery alone, and 20 patients underwent palliative debulking, but 10 were ineligible for this operation.
Although the combination of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy is currently suggested the standard practice for pseudomyxoma peritonei, not all patients are eligible for this protocol. In this study, hyperthermic intraperitoneal chemotherapy was suitable for 62% of patients with pseudomyxoma peritonei of appendiceal origin.

    ABSTRACT: Patients with pseudomyxoma peritonei (PMP) benefit from cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Reports on this modality usually have included only patients with successful HIPEC treatment, which can potentially cause biased results. We report the survival of a PMP population treated by CRS and HIPEC, including patients who were not eligible for HIPEC. The outcome of the whole population of 87 patients with PMP treated by CRS and HIPEC in Helsinki University Central Hospital between 2008 and 2011 was evaluated. The results of treatment were compared with 33 patients treated by serial debulking in our unit between 1984 and 2008. Of the 87 patients in the HIPEC-era group, 56 received HIPEC, 12 were treated non-radically in an attempt at HIPEC, 9 were debulked and 10 were referred back or transferred to palliative care without surgery. The 5-year overall survival for the debulking-era group and the HIPEC-era group were 67 and 69 %, respectively. The number of patients with no evidence of disease was higher in the HIPEC-era group (47/87) than that in the debulking-era group (8/33) at the end of the follow-up. Overall survival for patients who underwent successful CRS and HIPEC at 2 and 5 years was 95 and 93 %, respectively. The improved survival from using the CRS and HIPEC was not apparent after 5-year follow-up, when the whole patient population was included in the analysis. Even so, patients successfully treated by CRS and HIPEC manage well.
