Proton therapy (PT) is an important component of therapy for select cancers, but no formal study of geospatial access to PT has been conducted to date. Population data for 320.7 million people in 32,644 zip codes were analyzed. Median travel time was 1.61 (IQR 0.67-3.36) hours for children and 1.64 (IQR 0.69-3.33) hours for adults. Significant variation in travel time to nearest PT center was observed between states. The West has a longer median travel time of 3.51 (IQR 1.15-7.13) hours when compared to the Midwest (1.70, IQR 0.79-2.69), South (1.60, IQR 0.61-3.12) and Northeast (1.04, IQR 0.57-2.01).

Delays Experienced by Patients With Pediatric Cancer During the Health Facility Referral Process: A Study in Northern Tanzania.

JCO Glob Oncol 2020 11;6:1757-1765

Department of Oncology, Bugando Medical Centre, Mwanza, Tanzania.

Purpose: It is estimated that 50%-80% of patients with pediatric cancer in sub-Saharan Africa present at an advanced stage. Delays can occur at any time during the care-seeking process from symptom onset to treatment initiation. Referral delay, the time from first presentation at a health facility to oncologist evaluation, is a key component of total delay that has not been evaluated in sub-Saharan Africa.

Methods: Over a 3-month period, caregivers of children diagnosed with cancer at a regional cancer center (Bugando Medical Centre [BMC]) in Tanzania were consecutively surveyed to determine the number and type of health facilities visited before presentation, interventions received, and transportation used to reach each facility.

Results: Forty-nine caregivers were consented and included in the review. A total of 124 facilities were visited before BMC, with 31% of visits (n = 38) resulting in a referral. The median referral delay was 89 days (mean, 122 days), with a median of two facilities (mean, 2.5 facilities) visited before presentation to BMC. Visiting a traditional healer first significantly increased the time taken to reach BMC compared with starting at a health center/dispensary (103 236 days; = .02). Facility visits in which a patient received a referral to a higher-level facility led to significantly decreased time to reach BMC ( < .0001). Only 36% of visits to district hospitals and 20.6% of visits to health centers/dispensaries yielded a referral, however.

Conclusion: The majority of patients were delayed during the referral process, but receipt of a referral to a higher-level facility significantly shortened delay time. Referral delay for pediatric patients with cancer could be decreased by raising awareness of cancer and strengthening the referral process from lower-level to higher-level facilities.
