Abstract
(en) PURPOSE: To assess delays in treatment initiation of chemoradiation or radiation alone for patients with advanced stage cervical cancer in Botswana. METHODS AND MATERIALS: Females with locally advanced cervical cancer (stages IB2-IVB) were prospectively enrolled in an observational cohort study from 2015 to 2019. We evaluated delays at 30, 60, 90, 120, 150, and 180 or greater days between the date of diagnosis and treatment initiation. Factors associated with overall survival were modeled with multivariable Cox proportional hazards regression (aHR). Associations between delays in cervical cancer treatment initiation were evaluated via univariable logistic regression. RESULTS: Among the 556 patients included (median age = 47.9 years), 386 (69.4%) were females living with HIV with a median CD4 count of 448.0 cells/μL (IQR, 283.0-647.5 cells/μL) at diagnosis. Most patients had stages 2 (38.1%) or 3 (34.5%) cervical cancer. Early-stage patients experienced longer delays in treatment initiation compared to late-stage patients (P = .033). Early-stage patients with delays ≥90 days and pathology diagnosis between 2016 and 2019 (aHR, 0.34; P < .001) versus <90 days had a decreased risk of mortality, and those with delays ≥90 days and pathology diagnosis before 2016 (aHR, 5.67; P = .022) versus <90 days had an increased risk of mortality. Late-stage patients with delays ≥120 days and pathology diagnosis between 2018 and 2019 (aHR, 1.98; P = .025) versus <120 days had an increased risk of mortality. Early-stage patients with pathology diagnosis between 2016 and 2019 (odds ratio, 2.32; P = .043) versus before 2016 were more likely to experience delays ≥90 days, and late-stage patients who traveled >100 km to the treatment facility (odds ratio, 2.83; P < .001) versus <100 km were more likely to experience delays ≥120 days. CONCLUSIONS: Delays in care are common in Botswana, particularly for those living farther from the treatment clinic and at advanced stages. This paper is among the first to show an association between treatment delays and worsened overall survival at advanced stages of cervical cancer, highlighting the need for interventions to help patients receive timely care in global settings.
