Predictors of recurrence of peritoneal carcinomatosis among patients with colorectal cancer following cytoreductive surgery alone versus cytoreductive surgery plus HIPEC
To assess the efficacy on the prognosis of CRS and HIPEC compared with CRS only and to identify possible clinicopathological factors associated with the recurrence of PC.
Out of the 61 patients, 45 patients (73.8%) underwent CRS plus HIPEC, and 16 (26.2%) underwent CRS alone. The 1-year RFS was 55.7%, with a median of 12 months. The risk factors for recurrence identified in the univariate analysis were T4 primary tumor, high-grade, positive lymphovascular invasion (LVI), positive extracapsular nodal spread, and patients treated with CRS only, without HIPEC. In the multivariate analysis, the independent risk factors for recurrence were high grade and patients treated with CRS only.
Conclusion:
T4 primary tumor, high grade, positive LVI, and positive extracapsular nodal spread seemed to be important predictors of recurrence following the treatment of PC. Our study also demonstrated that the addition of HIPEC to CRS improved the RFS. (AU)
