Objective s: To evaluate travel distance in women with advanced or recurrent epithelial ovarian cancer (OC) undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) and the subsequent impact upon outcomes.
Methods: An IRB-approved single-institution prospective registry was queried for women with OC who underwent HIPEC from 1/1/2009-12/1/2020. Demographic, oncologic, and surgical data were recorded. The patient's home zip code was compared to the institutional zip code to determine travel distance using Google Maps. Patients were divided into three strata for analysis: 1) local: ≤50 miles, 2) regional: 51-99 miles, and 3) distant: ≥100 miles and univariate analysis was performed.
Results: Of 127 women, the median distance travelled was 57.0 miles (IQR: 20.6, 84.6). There were no significant differences in mild (28.3% vs. 26.3 vs. 24.1%), moderate (21.7% vs. 15.8% vs. 17.2%) or severe postoperative complications (11.7% vs. 5.3% vs. 17.2%) (p = 0.75) for local, regional and distant patients, respectively. There was no difference in progression-free survival (17.4 vs. 22.2 vs. 12.8 months, p > 0.05) or overall survival (57.3 vs. 61.6 vs. 29.2 months, p > 0.05) for local, regional or distant patients, respectively.
Conclusions: This study demonstrates that women with OC are willing to travel for HIPEC, with over 50% traveling > 50 miles. Our results suggest that women who travel for HIPEC procedures are not at increased risk for perioperative complications or worse oncologic outcomes than those local to HIPEC centers.
