RESUMO
Aim: To describe treatment-induced toxicities (TITs) and associated factors in Zimbabwean cancer patients receiving cisplatin. Methods: In total, 252 Zimbabwean women with cervical cancer, receiving cisplatin were followed up over 12 months for TITs and disease status. Results: Peripheral neuropathy (70%) and ototoxicity (53%) were most prevalent. Advanced disease (OR = 1.3; 95% CI = 1.1-1.5; p = 0.02), pain comedications (OR = 1.3; 95% CI = 1.1-1.5; p = 0.03), alcohol (OR = 2.8; 95% CI = 1.1-7.5; p = 0.04) and comorbidities (OR = 1.2; 95% CI = 1.1-1.4; p = 0.04) increased peripheral neuropathy and ototoxicity risk. Older age increased risk of disease progression (OR = 1.9; 95% CI = 1.4-3.0; p = 0.033). Conclusion: High peripheral neuropathy and ototoxicity prevalence were observed, which are not routinely monitored in Zimbabwe. There is a need for capacity building to incorporate comprehensive TIT testing and optimize cancer care in Zimbabwe.
Cancer treatment has side effects, also known as treatment-induced toxicities (TITs), that can lead to death if not management properly. African populations are more likely to develop TITs, however, not many studies research on TITs in Africans and why they are more prone to TITs. This study followed up 252 Zimbabwean women with cervical cancer, over 12 months for TITs and found that loss of sensation and ear complications most commonly occurred after treatment. Advanced disease, prescribed pain medication, alcohol consumption history and underlying diseases such as diabetes increased likelihood of TITs, while older age increased risk of unresponsive cancer. This study highlights a need to incorporate comprehensive monitoring for TITs for at-risk individuals toward improving cancer care.
