Thesis (MTech (Biomedical Technology))--Cape Peninsula University of Technology, 2011 / Introduction: A prospective study was conducted across the spectrum of cervical aberrancies with the aim of assessing the distribution of HPV relating to the degree of cervical abnormalities using polymerase chain reaction (PCR) and P16INK4A assay as a marker for cervical disease progression. Patient demographics including their sexual, contraceptive and screening history were evaluated to determine whether subsidiary risk factors contribute towards the development of cervical lesions among Namibian women. Methods: From Feb 2006 to March 2007, 187 women with abnormal cervical cytology were examined. Cervical smears were immunostained using the P16INK4A assay (Dakocytomation, Heidelberg, Germany). Brown discolourisation of the nucleus and/or cytoplasm of abnormal cells were considered positive for P16 immunoexpression. Absence of brown decolourisation in the nucleus or cytoplasm of abnormal cells was considered negative for P16 immunoexpression. DNA was successfully extracted from 182 specimens, and the respective samples were subjected to PCR using GP5+/6+ primers. Type-specific (HPV types 16 and 18) PCR were also applied. Patients’ sociodemographics, sexual and reproductive history, HIV status, contraceptive use and Pap smear history were all recorded.

Thesis (MTech (Radiography))--Cape Peninsula University of Technology, 2012 / Introduction: Brachytherapy plays an essential role in the management of patients with cervical cancer. The high cervical cancer burden in Africa presents challenges with regard to provision and sustainability of these services. This study analysed treatment outcomes of two brachytherapy modalities, high dose rate (HDR) and low dose rate (LDR) intracavitary treatment for patients with cervical cancer, and evaluated the problems and challenges of the provision of these services within the African context. Methodology: The study was conducted using a case study approach with mixed methods at two sites in Africa, one in South Africa (Centre I) and the other in Kenya (Centre II). The study explored factors and issues affecting definitive radiotherapy of the patient with cervical cancer at the two sites with a focus on the brachytherapy treatment. The case study provided an opportunity to collect in-depth data consisting of quantitative and qualitative components that generated numeric and textual data. Treatment outcomes of one site treating with HDR and the other LDR intracavitary brachytherapy were retrospectively analysed for a maximum sample size of 193 (91%) patients in the HDR group and 49 (100%) patients in the LDR group. All patients were treated with external beam radiation therapy (EBRT) using parallel opposed beams (POP) for the patients that received LDR brachytherapy, and four field box technique or POP for those that received HDR brachytherapy. The linear quadratic formula was used to calculate the equivalent dose in 2 Gy fractions (EQD2) between the two groups.

Até recentemente, a captura híbrida 2 (HC2) para detecção de um pool de HPV de alto risco oncogênico foi o método clínico mais estudado por este grupo. Entretanto, frente à evidente diferença no risco de evolução das lesões cervicais, a genotipagem do HPV através de análise do ácido nucléico passou a ser relevante. Objetivo: Avaliar a distribuição de infecções simples e múltiplas de diferentes tipos de HPV em mulheres com neoplasia intra-epitelial cervical de alto grau (NIC2 e NIC3). Sujeitos e Métodos: Foram avaliados os genótipos específicos de HPV da amostra cervical de 106 mulheres utilizando Roche Linear Array® human papillomavirus (LA-HPV) genotyping assay (Roche Diagnostics,USA). O material foi coletado antes da conização cervical. Foram comparadas as proporções de NIC2 e NIC3 em grupos de mulheres infectadas com tipos de HPV dos grupos filogenéticos Alfa7 (A7) e Alfa9 (A9). Três situações foram consideradas: mulheres com 1) infeccão simples; 2) infecção múltipla; 3) infecção simples e múltipla. Foram comparadas as proporções de diferentes combinações de tipos de HPV em grupos de mulheres com NIC2 e NIC3. Resultados: Pelo menos um tipo de HPV foi detectado em 99% das amostras. Infecções múltiplas foram detectadas em 68 (64,7%) das amostras. Os genótipos de alto risco mais freqüentemente detectados em infecção simples ou múltipla foram HPV16 (57,1%), HPV58 (24,7%), HPV33 (15,2%), HPV52 (13,3%), HPV31 (10,4%) e HPV51 (7,6%) e HPV18 (6,6%). A probabilidade de mulheres com NIC3 serem infectadas com HPV da espécie A9 foi maior. Os HPV 16 e ou 18, associados ou não com outros tipos virais foram mais frequentemente encontrados nas mulheres com NIC3 do que naquelas com NIC2. Conclusão: A severidade da NIC esteve associada com a presença de tipos de HPV incluídos na classificação filogenética A9 e por infecções que incluem HPV16 e 18 combinados ou não com outros genótipos de HPV / Abstract: Objective: To evaluate the distribution of single and multiple infections of different human papillomavirus (HPV) types in women with high grade cervical intraepithelial neoplasia (CIN2 and CIN3) and to assess the relation of the various combinations of virus with the severity of CIN. Subject and methods: Cervical samples from 106 women treated due to CIN2 (18) or CIN3 (88) were examined for specific HPV genotypes using Roche Linear Array® Human Papillomavirus (LA-HPV)(Roche Diagnostics, USA). The material was collected immediately before cervical conization. The proportion of CIN2 and CIN3 in groups of women infected with varying HPV phylogenetic groups Alpha7 (A7) and Alpha9 (A9) was compared. Three situations were considered: women with 1) single infection; 2) multiple infections; 3) the whole sample. The proportions of CIN2 and CIN3 in groups of women with different combinations of HPV types were compared. Results: At least one HPV type was detected in 99% of the whole series. Multiple infections were detected in 68 (64.7%) samples. The most frequent high-risk genotypes detected (single/multiple) were HPV16 (57.1%), HPV58 (24.7%), HPV33 (15.2%), HPV52 (13.3%), HPV31 (10.4%), HPV51 (7.6%) and HPV18 (6.6%). Women with CIN3 were more infected with HPV of species A9. HPV16 and/or HPV18, associated or not with other viral types, were more frequently found in specimens of women with CIN3 than in those of women with CIN2. Conclusions: the severity of high-grade CIN may be associated by the presence of HPV types included in the A9 phylogenetic classification and by infections including HPV16 and 18 combined or not with other HPV genotypes / Mestrado / Ciencias Biomedicas / Mestre em Tocoginecologia
