Perioperative Outcomes Of Cytoreductive Surgery With Hyperthermic Intraperitoneal Chemotherapy In Elderly Women With Epithelial Ovarian Cancer: Analysis Of A Prospective Registry
INTERNATIONAL JOURNAL OF GYNECOLOGICAL CANCER(2021)
Abstract
Objective To evaluate perioperative outcomes in elderly versus non-elderly women with advanced or recurrent epithelial ovarian cancer undergoing surgery with hyperthermic intraperitoneal chemotherapy (HIPEC). Methods A single-institution prospective registry was analyzed for women with ovarian cancer who underwent surgery with HIPEC from January 2014 to December 2020. Elderly age was defined as >= 65 years at surgery. Complications were defined according to the Accordion scale. Univariate and multivariable analysis was used to compare progression-free survival and overall survival. Results Of 127 women who underwent surgery with HIPEC, 33.1% (n=42) were >= 65 and 17.3% (n=22) were >= 70 years old. The median age for non-elderly and elderly patients were 55.7 +/- 8.3 versus 72.0 +/- 5.4 years, respectively (p<0.001). The majority of non-elderly versus elderly patients underwent HIPEC at the time of interval cytoreductive surgery following neoadjuvant chemotherapy (52.9% vs 73.8%, p=0.024). There were no differences in moderate (15.3% vs 26.2%) or severe postoperative complications (10.6% vs 11.9%, p=0.08), acute kidney injury (7.1% vs 16.7%, p=0.12), and length of stay (5.0 vs 5.0 days, p=0.56) for non-elderly versus elderly patients. With a median follow-up of 20 months (95% CI 9.1 to 32.7 months), there was no difference in progression-free survival (18.8 vs 15.7 months, p=0.75) or overall survival (61.6 months vs not estimable, p=0.72) for non-elderly versus elderly patients. Comparing patients 65-69 versus >= 70 years, progression-free survival (33.0 vs 12.5 months, p=0.002) was significantly improved in patients aged 65-69, without difference in overall survival (not estimable vs 36.0 months, p=0.91). On multivariable analysis, age >= 65 did not impact progression-free survival (p=0.74). Conclusions In this prospective registry of women with ovarian cancer, perioperative morbidity is not increased for non-elderly versus elderly patients following surgery with HIPEC. While age should not exclude patients from surgery with HIPEC, additional research is needed regarding oncologic benefits in elderly women.
