Purpose/Objective(s):

The number of cancer survivors from low-and-middle income countries (LMICs) is rising, but most research has been conducted in high income countries. While studies have characterized the detection and treatment of cervical cancer in Botswana, follow-up and survivorship care after treatment is a severely understudied area. We assessed short- and long-term survivorship visit adherence and factors associated with adherence in patients treated for cervical cancer in Botswana.

Materials/Methods:

Between 2015-2023, females with cervical cancer were prospectively enrolled in an observational cohort study. Short- (first 2 years post-treatment) and long-term (3-5 years post-treatment) visit adherence was defined as completing clinic visits at timepoints recommended according to the Botswana National Cervical Cancer Guidelines: biannual (every six months) visits for short-term and annual visits for long-term. Generalized estimating equations (aOR) were used to evaluate factors associated with short-term and long-term adherence.

Results:

This cohort included 1181 females treated with definitive or curative intent surgery- or radiation-based primary treatment, with a median age of 47.7 years (IQR, 41.6-58.2 years) and 68.6% living with HIV. Among the short-term analytic cohort (n=772), 45.2% (n=382), 38.2% (n=323), 36.0% (n=304), 33.7% (n=285) were adherent at 6, 12, 18, and 24 months, respectively. On multivariable analysis (n=772), patients who traveled =100 km to the treatment facility (aOR 0.35, p<0.001), were of advanced stage (III-IV) cervical cancer (aOR 0.69, p=0.007), and had to follow-up during the COVID-19 pandemic (aOR 0.72, p=0.005) were less likely to be adherent; patients were less likely to attend subsequent clinic visits compared to the initial 6 month visit: 12 month (aOR 0.82, p=0.002), 18 month (aOR 0.81, p=0.002), and 24 month (aOR 0.81, p=0.002). Among the long-term analytic cohort (n=362), 36.3% (n=151), 32.2% (n=134), and 27.9% (n=116) were adherent at 3, 4, and 5 years, respectively. On multivariable analysis (n=362), patients who traveled =100 km to the treatment facility (aOR 0.36, p<0.001) were less likely to be adherent; patients were less likely to attend subsequent clinic visits compared to the initial 3 year visit: 5 year (aOR 0.57, p=0.009).

Conclusion:

Adherence to recommended follow-up care in cervical cancer survivors in Botswana is suboptimal. Strategies to help survivors, particularly those living farther away from treatment facilities and of advanced stage (III-IV) disease, are needed to reduce cervical cancer mortality and improve adherence, in addition to enhanced focus on providing comprehensive survivorship care beyond visit completion.
