Abstract
Background
Several studies suggest that young patients may derive less oncologic benefit from surgical resection of cancers compared with older patients. We hypothesized that young patients may have worse outcomes following cytoreductive surgery with hyperthermic intraperitoneal chemoperfusion (CRS/HIPEC) for peritoneal metastases.
Methods
Perioperative and oncologic outcomes in adolescent and young adults (AYA), defined as younger than age 40 years (n = 135), undergoing CRS/HIPEC between 2001 and 2015 were reviewed and compared with middle-aged adults, defined as aged 40–65 years (n = 684).
Results
The two groups were similar with regards to perioperative characteristics except that AYA were more likely to be symptomatic at presentation (65.2 vs. 50.9%, p = 0.003), had lower Charleson comorbidity index (median 6 vs. 8, p < 0.001), were less likely to receive neoadjuvant chemotherapy (32.8 vs. 42.5%, p = 0.042), and had longer operative times (median 543 vs. 493 min, p = 0.010). Postoperative Clavien–Dindo grade 3–4 morbidity was lower in AYA (17 vs. 26%, p = 0.029), and they required fewer reoperations for complications (3.7 vs. 10.4%, p = 0.014). AYA had longer median overall survival (103.6 vs. 73.2 months, p = 0.053). In a multivariate Cox regression analysis, age was an independent predictor of improved overall survival [hazard ratio 0.705; 0.516–0.963, p = 0.028].
Conclusions
Young patients with peritoneal metastases derive similar benefits from CRS/HIPEC as middle-aged patients. Young age should not be a deterrent to consideration of CRS/HIPEC for peritoneal metastases.
