    (Human Resources for Health, 2020) Byamugisha, Josaphat; Munabi, Ian G.; Mubuuke, Aloysius G.; Mwaka, Amos D.; Kagawa, Mike; Okullo, Isaac; Niyonzima, Nixon; Lusiba, Pastan; Ainembabazi, Peruth; Kankunda, Caroline; Muhumuza, Dennis D.; Orem, Jackson; Atwine, Diana; Ibingira, Charles
    Cancer incidence and mortality in sub-Saharan Africa are increasing and do account for significant premature death. The expertise of health care providers is critical to downstaging cancer at diagnosis and improving survival in low- and middle-income countries. We set out to determine the training needs of health care providers for a comprehensive oncology services package in selected hospitals in Uganda, in order to inform capacity development intervention to improve cancer outcomes in the East African region. Methods: This was a cross-sectional survey using the WHO Hennessey-Hicks questionnaire to identify the training needs of health workers involved in cancer care, across 22 hospitals in Uganda. Data were captured in real time using the Open Data Kit platform from which the data was exported to Stata version 15 for analysis using the Wilcoxon signed-rank test and Somers-Delta. Results: There were 199 respondent health professionals who were predominately female (146/199, 73.37%), with an average age of 38.97 years. There were 158/199 (79.40%) nurses, 24/199 (12.06%) medical doctors and 17/199 (8.54%) allied health professionals. Overall, the research and audit domain had the highest ranking for all the health workers (Somers-D = 0.60). The respondent’s level of education had a significant effect on the observed ranking (P value = 0.03). Most of the continuing medical education (CME) topics suggested by the participants were in the clinical task-related category. Conclusion: The “research and audit” domain was identified as the priority area for training interventions to improve oncology services in Uganda. There are opportunities for addressing the identified training needs with an expanded cancer CME programme content, peer support networks and tailored training for the individual health care provider.

    Quantitative expression of estrogen, progesterone and human epidermal growth factor receptor-2 and their correlation with immunohistochemistry in breast cancer at Uganda Cancer Institute
    (Public Library of Science, 2025-01) Wannume, Henry; Niyonzima, Nixon; Kalungi, Sam; Okuni, Julius Boniface; Okecha, Tonny; Kakungulu, Edward; Kiwuwa, Steven Mpungu; Waiswa, Geoffrey; Kadhumbula, Sylvester; Namayanja, Monica; Nabwana, Martin; Orem, Jackson
    The detection of Estrogen Receptor (ER), Progesterone Receptor (PR), and Human epidermal growth factor receptor 2 (HER-2) is important for the stratification of breast cancer and the selection of therapeutic modalities. This study aimed to determine the quantitative expression of ER, PR and HER-2 using Immunohistochemistry and their correlation with quantitative baseline Ct values measured using Quantitative Polymerase Chain Reaction (PCR). This study also assessed the use of fresh breast tissue biopsies preserved in RNAlater solution in the quantitative detection of these receptors using PCR technique. The study evaluated 20 matched formalin fixed paraffin embedded and RNAlater preserved samples for ER, PR, and HER-2 using IHC and quantitative PCR technique. One portion of the breast tissue biopsy was fixed immediately in 10% neutral buffered formalin and another was preserved in RNAlater. After the histological confirmation of breast cancer by the H&E technique, formalin fixed paraffin embedded tissues (FFPE)—positive cases were matched with their corresponding RNAlater samples for IHC and qPCR. The extracted RNA was quantified using Nanodrop technology, resulting into complementary DNA. ER and PR using IHC were expressed in 60% (n = 12) of the study samples and were negative in 40% (n = 8) of samples. HER-2 was negative in 70% (n = 14) of study samples, 25% (n = 5) positive, and 5% (n = 1) equivocal. With the quantitative expression of ER, PR, and HER-2 being reported in the IHC triple—negative breast cancer cases. The mean Ct values for the hormonal receptors correlated with what has been previously studied with ER at 19.631, PR at 25.410 and HER-2 at 25.695. There was no statistically significant difference between the mean Ct values of RNAlater and FFPE with their P-values being 0.9919, 0.0896 and < 0.0001 for ER, PR, and HER-2 respectively. P-values; 0.9919 and 0.0896 for ER and PR respectively being greater than 0.05 it’s a borderline significance although HER-2 had a statistical significance. With a concordance in the detection of these breast cancer hormonal receptors, qPCR can be used in our setting considering the delays that may be associated in following the samples through IHC processing.

    Strengthening Laboratory Diagnostic Capacity to Support Cancer Care in Uganda
    (American journal of clinical pathology, 2021) Niyonzima, Nixon; Wannume, Henry; Kadhumbula, Sylivestor; Wasswa, Hassan; Osinde, Godfrey; Mulumba, Yusuf; Tusabe, Tobias; Kalungi, Samuel; Orem, Jackson
    An accurate cancer diagnosis is critical to providing quality care to patients with cancer. We describe the results of a laboratory improvement process that started in 2017 to improve access to cancer diagnostics at the Uganda Cancer Institute (UCI). The overall objective of the project was to build capacity for the provision of quality and timely laboratory diagnostics to support cancer care in Uganda. A phased multistep approach was used to improve laboratory capacity, including staff training, additional staff recruitment, equipment overhaul, and optimization of the supply chain. The program led to the establishment of a pathology laboratory that handled 5,700 tissue diagnoses in 2019. Immunohistochemistry services are now offered routinely. Turnaround time for histopathology has also reduced from an average of 7 to 14 days to 5.4 days. The main clinical laboratory has also increased both the test volume and the test capacity, with the additional establishment of a molecular diagnostics laboratory. Our project shows a pathway to the improvement of laboratory diagnostic capacity in cancer care centers in sub-Saharan Africa (SSA). Improved laboratory diagnostic capacity is critical to improving cancer care in SSA and more rational use of targeted therapies.

    United against cancer: prevention to end-of-life care—highlights from the Uganda Cancer Institute–Palliative Care Association of Uganda Joint International Conference on Cancer and Palliative Care and the 7th Palliative Care Conference, 24–25 August 2017, Kampala, Uganda
    (Ecancermedicalscience, 2017) Downing, Julia; Ddungu, Henry; Kiyange, Fatia; Batuli, Mwazi; Kafeero, James; Kebirungi, Harriet; Kiwanuka, Rose; Mugisha, Noleb; Mwebesa, Eddie; Mwesiga, Mark; Namukwaya, Elizabeth; Niyonzima, Nixon; Phipps, Warren; Orem, Jackson
    The Uganda Cancer Institute (UCI) and the Palliative Care Association of Uganda (PCAU) jointly hosted an international conference oncancer and palliative care in August 2017 in Kampala, Uganda. At the heart of the conference rested a common commitment to see patientcare improved across Uganda and the region. The theme – United Against Cancer: Prevention to End-of-Life Care – reflected this jointvision and the drive to remember that cancer care should include prevention, early diagnosis and screening, treatment, rehabilitation andpalliative care. The conference brought together 451 delegates from 17 countries. The key themes of the conference included: the importanceof the World Health Assembly Resolutions on Palliative Care (2014) and cancer care (2017); the need to develop a National CancerControl Programme; strategies for effective cancer diagnosis and treatment in low- and middle-income countries; advocacy, human rightsand access to essential medicines, including access to opioids and nurse prescribing; paediatric care; leadership and commitment; collaboration;resources (financial and human), the recognition that palliative care is not limited to cancer care and the importance of learningfrom each other. The conference also gave the opportunity to celebrate the 50th Anniversary of the UCI, with a celebration dinner attended by the Minister of Health and the US Ambassador. Participants reported that the conference was a forum that updated them in all aspects of cancer and palliative care, which challenged their knowledge, and was enlightening in terms of current treatment options for individuals with cancer. The benefits of having a joint conference were recognized, allowing for further networking between cancer and palliative care organizations. This conference, highlighting many developments in cancer and palliative care, served as a unique opportunity to bring people together and unite them in developing cancer and palliative care
