Abstract

Background

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are used in the management of selected peritoneal malignancies. While most patients achieve long-term disease-free survival, there remains a group with early recurrence (ER). We aim to investigate the clinical factors associated with ER.

Methods

A retrospective review of a prospectively maintained database of CRS-HIPEC patients treated between April 2001 and Feb 2016 was performed. ER was defined as recurrence within 12 months of CRS-HIPEC. Patients were stratified according to time to recurrence and only patients with at least 12-month follow-up were included. Perioperative factors were investigated, and subgroup analyses of colorectal, ovarian and appendiceal groups were performed.

Results

Of the 144 patients included, 30.6% were colorectal, 36.8% ovarian and primary peritoneal, 24.3% appendiceal, 2.1% mesothelioma and 6.3% were of other origins. Thirty-nine patients (27%) suffered ER. Univariable and multivariable analyses revealed that primary tumour type (p = 0.02) and post-CRS adjuvant treatment (p = 0.04) were associated with ER. Appendiceal patients had a lower odds of ER compared to colorectal patients [OR = 0.15 (0.043–0.502) p < 0.002]. Patients who received post-CRS adjuvant treatment had a lower odds of ER than patients without adjuvant treatment [OR = 0.32; (0.128–0.818) p = 0.02].

Conclusion

There remains a 27% risk of ER after CRS-HIPEC. Better patient selection and the administration of adjuvant chemotherapy may help to reduce ER.
