This was a prospective, quantitative comparative study. The aim of the study was to evaluate acute toxicity of radical combination therapy, in the form of radiotherapy and chemotherapy, in HIV +ve patients on HAART and HIV -ve patients for cervical cancer at CDH, Lusaka, Zambia. The specific objectives were to compare acute toxicity in HIV +ve on HAART and HIV -ve patients and to assess the level of severity in the levels of toxicity. The study was conducted from January 2010 to December 2010. A hundred and twenty stage IB₂-IIIB cervical cancer patients were serially recruited and assigned study numbers for identification and confidentiality. Participants received Cisplatin based radical chemoradiation for five to six weeks during which time they were assessed for acute reactions and data was prospectively collected. Four systems namely Genitourinary, Haematopoietic, Skin, and Gastrointestinal were used for the assessment of toxicity in the study. Toxicity was scored using the NCI CTC v2.0. The results of this study showed that, major acute reactions in the CDH study participants were grade 3 leucopoenia (five in each study arm) and one grade 3 acute skin toxicity in the HIV +ve arm. Results also revealed that there were three HIV +ve study participants with grade 3 vomiting and one HIV –ve. There was one grade 3 anaemia in the HIV +ve arm, one grade 3 anaemia in the HIV –ve arm and one grade 4 anaemia in the HIV +ve arm. However, only the incidence of grade 3 leucopoenia in both study arms and vomiting in the HIV +ve study participants was significantly higher. This study demonstrated that radical chemoradiation is well tolerated by HIV +ve patients with intact immunity. Toxicity was usually mild and reversible and no exaggerated toxicities beyond those generally associated with single-agent Cisplatin were observed in the HIV +ve study participants. Therefore, radical chemoradiation in conventional doses can safely be given to cervical cancer HIV +ve patients who are on HAART.
