Purpose:
A combination of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) is effective for some peritoneal malignancies. However, the indications for elderly patients remain unclear, with substantial postoperative morbidity and mortality being problematic.
Materials:
Clinical data were analyzed in 42 patients undergoing CRS + HIPEC for peritoneal malignancy. The primary tumor was located in the appendix in 32 cases and elsewhere in 10 cases. Operative results and survival data were compared between patients aged ≥70 and <70 years.
Results:
Fourteen patients were older than 70 years. Elderly patients had a higher peritoneal cancer index (32.0 vs. 21.5), higher CA19-9 level (189.0 vs. 28.1), and higher frequency of grade 4-5 complications (5/9 vs. 2/26) than the younger patients. Grade 4-5 respiratory failure occurred in three elderly patients. There was a significant difference of postoperative survival between the elderly patients and younger patients, with 5-year survival rates being 41.3 and 74.2%, respectively (p = 0.0166). The poor prognosis of elderly patients was related to the higher frequency of grade 4-5 complications.
Conclusions:
Elderly patients were referred for treatment with more advanced disease than younger patients. An age ≥70 years was associated with more frequent grade 4-5 complications and worse survival. Performing CRS + HIPEC in elderly patients should be considered carefully due to the risk of severe complications, especially respiratory failure.
