Abstract

BACKGROUND:

There are limited data on the travel burden for cancer patients with rare tumor types, such as Merkel cell carcinoma (MCC).

OBJECTIVE:

The objective of this study was to understand the travel burden of MCC patients.

METHODS:

This study used data from an MCC registry at the Seattle Cancer Care Alliance (SCCA). All MCC patients enrolled at SCCA with a valid 3-digit ZIP code were included. Patients were followed up from January 1, 2012 until their last follow-up, death, or end of data (January 1, 2017). Travel burden was measured by one-way travel distance to SCCA from each patient's 3-digit ZIP code. Patient demographics, tumor characteristics, and follow-up visit were evaluated and stratified by one-way driving distance of ≤300 and >300 miles.

RESULTS:

A total of 391 MCC patients were included (68% men, mean age = 67 years [±SD = ±11 years], 67% residing in the West, and 70% white). At diagnosis, 53% of the patients had Stage III or IV MCC. Mean one-way distance traveled by patients was 1,137 (median: 813) miles, and 57% of patients traveled >300 miles. Compared to patients who traveled ≤300 miles, those who traveled >300 miles were more likely to be <70 years old (46% vs 65%; P < 0.001), were diagnosed with advanced stage (III or IV) MCC (46% vs 59%; P = 0.01), had shorter follow-up in the cancer registry (mean: 509 vs 212 days; P < 0.001), and had fewer visits during follow-up (mean: 5.2 vs 2.5; P < 0.001).

CONCLUSIONS:

In this single cancer center study, the majority of MCC patients trav-eled long distances to receive expert care. Longer travel distances appeared to be associated with younger age, a more advanced stage of cancer at study entry and fewer in-clinic visits, suggesting that travel burden may impact timely and adequate patient care for this rare cancer.
