Background
Despite the positive survival results of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC), criticisms have been put forward regarding the safety of this treatment as a result of a high morbidity rate. Muscle depletion (sarcopenia) is associated with the occurrence of postoperative complications. The purpose of this study was to determine the association between sarcopenia and postoperative morbidity after CRS-HIPEC for peritoneal carcinomatosis from colorectal cancer by distinguishing the complications linked to CRS itself and those associated with chemotherapy (HIPEC) toxicities.
Methods
Data concerning 97 consecutive patients who had undergone CRS-HIPEC were recorded. We analyzed the events occurring within 30 days after surgery that were prospectively recorded in a database. Sarcopenia was assessed using the L3 muscle index on computed tomography performed during the 2 months preceding surgery.
Results
The sarcopenic patients experienced significantly more chemotherapy toxicities (57 vs. 26 %; p = 0.004) and especially neutropenia (36 vs. 17 %; p = 0.04) than their nonsarcopenic counterparts. There was no difference in complications linked to the CRS procedure between sarcopenic and nonsarcopenic patients. In the multivariate analysis, sarcopenia was the only parameter independently associated with the risk of chemotherapy toxicity (odds ratio 3.97; 95 % confidence interval 1.52–10.39; p = 0.005).
Conclusions
Despite the local administration of chemotherapy, systemic toxicity was observed in sarcopenic patients after CRS-HIPEC. This relationship favors new treatment strategies with white blood cell growth factors or chemotherapy dosing based on muscle value.
