Clinicopathological characteristics and treatment outcomes of oesophageal cancer patients in Uganda.

Background: Oesophageal cancer is the seventh most common cancer and the sixth leading cause of cancer death worldwide, and its incidence varies globally. In Uganda, the incidence and trend are on the increase. However, there is a paucity of published data regarding this population's oesophageal cancer clinicopathologic characterisation and treatment outcomes. Objectives: To study the patients' clinicopathologic characteristics and treatment outcomes of oesophageal cancer over 10 years at the Uganda Cancer Institute. Methods: Patients' charts with histologically confirmed diagnoses of oesophageal cancer for 2009-2019 were identified. Case information, which included patient demographics, history of alcohol use or smoking, tumour location, histological type, tumour grade, clinical TNM (Tumour, Node, Metastasis) staging treatment exposure and treatment outcomes, was evaluated retrospectively. The median survival time was estimated with the Kaplan-Meier method and the median follow-up period was estimated using the reverse Kaplan-Meier. Results: 1,965 oesophageal cancer patients were identified; 1,380(70.23%) were males and 585(29.77 %) females, their mean age was 60.20 years (±12.66). Most males had a history of both alcohol consumption and smoking 640(46.38%). The lower third of the oesophagus was the most common anatomical location 771(39.24%). The majority had squamous cell carcinoma histological type 1,783(90.74%) followed by adenocarcinomas 182(9.26%) in the distal oesophagus. Poorly differentiated tumour grade 743(37.81%) was predominant. The majority of the patients were in stage IVB, 733(37.30%), and most patients were planned for the best supportive care, 731(37.20%). Radiation alone was offered to 621(31.60%) and feeding gastrostomy to 249(12.70%). Treatment outcomes: at the time of the current analysis, 58.68% had died, 1.48% were alive and 39.84% were lost to follow-up. The median follow-up period was 65 months (IQR:35.83-83.30) with a median survival time of 4.47 months (95% CI: 4.17-4.80). Conclusion: Treatment outcomes of Ugandan oesophageal cancer patients seeking care are poor as most patients present with advanced disease. There is a significant loss of follow-up after treatment initiation. Therefore, reduction in exposure to known modifiable risk factors, early detection and timely referral for treatment strategies are needed to improve outcomes of these patients in our population. Designing interventions to improve treatment adherence is necessary.

Factors associated with severity and anatomical distribution of diabetic foot ulcer in Uganda: a multicenter cross-sectional study.

BACKGROUND: Diabetic foot ulcer (DFU) is a devastating complication of diabetes mellitus (DM) that is associated with increased mortality, morbidity, amputation rate and economic burden. This study aimed at identifying the anatomical distribution and factors associated with severity of DFU in Uganda. METHODOLOGY: This was a multicenter cross-sectional study conducted in seven selected referral hospitals in Uganda. A total of 117 patients with DFU were enrolled in this study between November 2021 and January 2022. Descriptive analysis and modified Poisson regression analysis were performed at 95% confidence interval; factors with p-value < 0.2 at bivariate analysis were considered for multivariate analysis. RESULTS: The right foot was affected in 47.9% (n = 56) of patients, 44.4% (n = 52) had the DFU on the plantar region of the foot and 47.9% (n = 56) had an ulcer of > 5 cm in diameter. The majority (50.4%, n = 59) of patients had one ulcer. 59.8% (n = 69) had severe DFU, 61.5% (n = 72) were female and 76.9% had uncontrolled blood sugar. The mean age in years was 57.5 (standard deviation 15.2 years). Primary (p = 0.011) and secondary (p < 0.001) school educational levels, moderate (p = 0.003) and severe visual loss (p = 0.011), 2 ulcers on one foot (p = 0.011), and eating vegetables regularly were protective against developing severe DFU (p = 0.03). Severity of DFU was 3.4 and 2.7 times more prevalent in patients with mild and moderate neuropathies (p < 0.01), respectively. Also, severity was 1.5 and 2.5 higher in patients with DFU of 5-10 cm (p = 0.047) and in those with > 10 cm diameter (p = 0.002), respectively. CONCLUSION: Most DFU were located on the right foot and on the plantar region of the foot. The anatomical location was not associated with DFU severity. Neuropathies and ulcers of > 5 cm diameter were associated with severe DFU but primary and secondary school education level and eating vegetables were protective. Early management of the precipitating factors is important to reduce the burden of DFU.

Clinical presentation and outcomes in children with retinoblastoma managed at the Uganda Cancer Institute.

Background: The majority of patients with retinoblastoma, the most common intraocular cancer of childhood, are found in low-and middle-income countries (LMICs), with leukocoria being the most common initial presenting sign and indication for referral. Findings from the current study serve to augment earlier findings on the clinical presentation and outcomes of children with retinoblastoma in Uganda. Methods: This was a retrospective study in which we reviewed records of children admitted with a diagnosis of retinoblastoma at the Uganda Cancer Institute from January 2009 to February 2020. From the electronic database, using admission numbers, files were retrieved. Patient information was recorded in a data extraction tool. Results: A total of 90 retinoblastoma patients were studied, with a mean age at the first Uganda Cancer Institute (UCI) presentation of 36.7 months. There were more males (57.8%) than females, with a male to female ratio of 1.37 : 1. The majority (54.4%) had retinoblastoma treatment prior to UCI admission. The most common presenting symptoms were leukocoria (85.6%), eye reddening (64.4%), and eye swelling (63.3%). At 3 years of follow-up after index admission at UCI, 36.7% of the patients had died, 41.1% were alive, and 22.2% had been lost to follow-up. The median 3-year survival for children with retinoblastoma in our study was 2.18 years. Significant predictors of survival in the multivariate analysis were follow-up duration ( P ¯ < 0.001 ), features of metastatic spread (P = 0.001), history of eye swelling (P = 0.012), and bilateral enucleation (P = 0.011). Conclusions: The majority of children who presented to the Uganda Cancer Institute were referred with advanced retinoblastoma, and there was a high mortality rate. Retinoblastoma management requires a multidisciplinary team that should include paediatric ophthalmologists, paediatric oncologists, ocular oncologists, radiation oncologists, and nurses.

The role and attributes of social networks in the provision of support to women after stillbirth: experiences from Uganda.

INTRODUCTION: Communities exert stigma on mothers after stillbirth despite their potential to offer social support to the grieving family. Maternal healthcare-seeking behaviors are socially reinforced rendering a social network approach vital in understanding support dynamics which when utilized can improve community response to mothers experiencing stillbirth. However, the form and direction of social support for women when in need is not clear. The study explored the role and attributes of women's social networks in the provision of support to mothers who have experienced a stillbirth in Uganda. METHODS: An exploratory cross-sectional study design adopting a social network approach was conducted. Data collection following established procedures was conducted on a convenient sample of 17 mothers who had experienced a stillbirth six months before the study. Frequencies and bivariate analysis were conducted to determine the factors influencing the provision of social support from 293 network members elicited during the alter generation. We then performed a Poisson regression on each of the social support forms and the explanatory variables. Network structure variables were calculated using UCINET version 6 while Netdraw facilitated the visualization of networks. RESULTS: Overall, social support was available from all network relations mentioned by the respondents. No major variations were observed between the two time periods during pregnancy and following a stillbirth. The most common support received was in form of intangible support such as emotional and information support, mainly from females who were married and from the naturally occurring networks such as family and friends. We also observed that social support followed patterns of network relational characteristics including trust, frequency of contact and alters counted on for support more likely to provide the same. CONCLUSIONS: A great potential for social support exists within women's social networks to help address stillbirth risk factors during pregnancy and cope after experiencing the same. Alter characteristics like being female, married, and from naturally occurring networks together with relational characteristics such as trust, frequency of contact, and count on alter for support were predictors of eventual social support. Interventions aiming at addressing stillbirth risks at the community level ought to harness these network characteristics for benefits to the mothers.

Characteristics and outcomes of patients with multiple myeloma at the Uganda Cancer Institute.

PURPOSE: Data on multiple myeloma (MM) in sub-Sahara Africa is scarce. In Uganda, there is a progressively increasing incidence of MM over the years. METHODS: We performed a retrospective study on 217 patients with MM at the UCI using purposive sampling method. The objectives of the study were to determine the clinical characteristics, treatment outcomes, 5 year overall survival and predictors of survival of patients with MM at the UCI from 01 January 2008 to 31 December 2012. RESULTS: There were 119 (54.8%) males; the mean(SD) age of the study population at presentation was 59(12.8) years; 183(84.3%) patients presented with bone pain, and 135 (61.9%) had skeletal pathology; 186(85.3%) were HIV negative, and 152(70%) had Durie-Salmon stage III. The median overall survival was 2.5 years, (95% CI, 0.393-0.595); factors significantly associated with worse survival were Durie-Salmon stage III disease, HR=5.9, 95% CI (1.61 - 21.74; P=0.007) and LDH >225 U/L HR=3.3, 95% CI (0.57 - 5.92; P=0.029). CONCLUSION: Most patients with multiple myeloma at the UCI were diagnosed at a relatively young age, presented with late stage disease and bone pain, and had a shorter survival time. Factors associated with worse survival were Durie-Salmon stage III and LDH >225 U/L.

Health facilities' readiness for safe surgical care provision in Uganda and the Eastern Democratic Republic of Congo during Ebola and COVID-19 era.

OBJECTIVE: This study aimed to assess health facilities' readiness to provide safe surgical care during Ebola and COVID-19 era in Uganda and in the Eastern DR Congo. METHODS: A cross-sectional study was conducted in selected national, regional referral and general hospital facilities in Uganda and in the eastern part of DR Congo from 1st August 2020 to 30th October 2020. Data was analysed using Stata version 15. RESULTS: The participation rate was of 37.5 % (72/192) for both countries. None of the hospitals fulfilled the readiness criteria for safe surgical care provision in both countries. The mean bed capacity of participating health facilities (HF) was 184 in Eastern DR Congo and 274 in Uganda with an average surgical ward bed capacity of 22.3 % (41/184) and 20.4 % (56/274) respectively. The mean number of operating rooms was 2 and 3 in Eastern DR Congo and Uganda respectively. Nine hospitals (12.5 %) reported being able to test for Ebola and 25 (34.7 %) being able to test for COVID-19. Postponing of elective surgeries was reported by 10 (13.9) participating hospitals. Only 7 (9.7 %) hospitals reported having a specific operating room for suspect or confirmed cases of Ebola or COVID-19. Appropriate Personal Protection Equipment (PPE) was reported to be available in 60 (83.3 %) hospitals. Most of the staff had appropriate training on donning and doffing of PPE 40 (55.6 %). Specific teams and protocols for safe surgical care provision were reported to be present in 61 (84.7 %) and 56 (77.8 %) respectively in Uganda and Eastern DR Congo participating hospitals. CONCLUSIONS: The lack of readiness to provide safe surgical care during Ebola and COVID-19 era across the participating hospitals in both countries indicate a need for strategies to enhance health facility supplies and readiness for safe surgical provision in resource-limited settings.

Survival of patients with cancer associated thrombosis at the Uganda Cancer Institute.

BACKGROUND: The occurrence of venous thromboembolism (VTE) in patients with cancer leads to a reduced life expectancy. There is an increased incidence of cancer and its associated mortality in Uganda. We described the survival and characteristics of patients with cancer associated thrombosis (CAT) in a tertiary oncology centre in Uganda. METHODS: We performed a retrospective study on patients with CAT at the Uganda Cancer Institute (UCI) using a homogenous purposive sampling method. RESULTS: One hundred and eleven patients with documented VTE were included in the analysis. At entry, the mean age was 52.4 years, and 69 were female. Ninety eight had deep venous thrombosis, while 12 had pulmonary embolism. The most common cancer diagnoses were haematologic (30), gynaecologic (20) and prostate (17) cancers. Treatment regimens included anticoagulation with low-molecular weight heparin (LMWH) (72) and combined LMWH with warfarin (22). The median overall survival (OS) was 6.3 months, with a 1-year survival rate of 41.5%. Patients with significantly increased hazard of mortality were those with upper gastrointestinal (UGI) malignancies, colorectal and breast cancers. Patients with a body mass index of 25-29.9 kg/m2 (overweight) had a slightly reduced hazard of mortality. CONCLUSION: The OS of patients with CAT at the UCI is short. Most patients with CAT presented with advanced stage cancers and at a relatively young age. Patients with UGI, colorectal and breast cancers had increased hazards of mortality, whereas those who were overweight had a slight reduction in the hazard of mortality.

Increasing access to quality anticancer medicines in low- and middle-income countries: the experience of Uganda.

Cancer is one of the leading causes of death with 9.6 million deaths registered in 2018, of which 70% occur in Africa, Asia and Central and South America, the low-and middle-income countries (LMICs). The global annual expenditure on anticancer medicines increased from $96 billion in 2013 to $133 billion in 2017. This growth rate is several folds that of newly diagnosed cancer cases and therefore estimated to reach up to $200 billion by 2022. The Uganda Cancer Institute, Uganda's national referral cancer center, has increased access to cancer medicines through an efficient and cost-saving procurement system. The system has achieved cost savings of more than USD 2,000,000 on a total of 37 of 42 essential cancer medicines. This has resulted in 85.8% availability superseding the WHO's 80% target. All selected products were procured from manufacturers with stringent regulatory authority approval or a proven track record of quality products.

Use of face masks to limit the spread of the COVID-19 among western Ugandans: Knowledge, attitude and practices.

BACKGROUND: The world is grappling with an ever-changing COVID-19 pandemic using preventive measures such as personal hygiene, face masks, restrictions on travel and gatherings in communities, in addition to a race to find a vaccine. The purpose of this study was to evaluate the knowledge, attitudes and practices of the western Uganda community on the proper use of face masks to mitigate the spread of COVID-19. METHODS: A cross-sectional study using a structured questionnaire was carried out from 1st July to 10th July 2020 among western Ugandans of consent age of 18 years and above. Data was analysed using Stata version 14.2. RESULTS: Among the respondents (n = 1114), the mean age was 30.7 (SD 11.1), 51% were males, 53.9% married and 43% had attained secondary education. Most participants (60.1%, n = 670) had satisfactory knowledge on the use of face masks and participants at a tertiary education level [AOR 2.6 (95% CI: 1.42-4.67; p = 0.002)] were likely to have satisfactory knowledge than participants who had not education. On attitude, most respondents (69.4%) were confident enough to correctly put on a face mask; 83.4% believed that a face mask can protect against COVID-19 and 75.9% of respondents had never shared their face mask. The majority of respondents (95.2%) agreed wearing face masks in public places was important to protect themselves against COVID-19; 60.3% reported washing their hands before wearing and after removing the face mask. Unfortunately, 51.5% reported removing the face mask if they needed to talk to someone. CONCLUSION: Despite the satisfactory knowledge, good attitude and practices, there is still much more to be done in terms of knowledge, attitude and practices among participants. Government, non-governmental organizations and civil society should improve sensitization of populations on how to behave with face masks while talking to avoid the spread of the COVID-19 among western Ugandans.

Challenges in Access and Utilization of Sexual and Reproductive Health Services Among Youth During the COVID-19 Pandemic Lockdown in Uganda: An Online Cross-Sectional Survey.

Introduction: Sexual and Reproductive Health access to Information services is still a pressing need for youth in Uganda even during the COVID-19 pandemic, which has disrupted health care access in many countries. The aim of this study was to explore the challenges in access and utilization of sexual and reproductive health services as faced by youth during the COVID-19 pandemic lockdown in Uganda. Methods: This was a cross-sectional study carried out from 28th April 2020 to 11th May 2020 in Uganda. An online questionnaire was disseminated to youth aged between 18 and 30 years over a period of 14 days. The snowball sampling method was used to recruit participants. STATA version 14.2 was used for statistical analysis. Results: Of 724 participants, 203 (28%) reported that they did not have access to information and/or education concerning sexual and reproductive health (SRH). More than a quarter of the participants (26.9%, n = 195) reported that testing and treatment services of sexually transmitted infections were not available during the lockdown, and 27.2% could not obtain contraceptive supplies. Access to HIV/AIDS care services and menstrual supplies was also impaired. Lack of transportation was the commonest factor cited as limiting access to SRH services during the lockdown (68.7%), followed by the long distance from home to SRH facilities (55.2%), high cost of services (42.2%) and the curfew (39.1%). Sexually transmitted infections were the commonest SRH problems related to SRH during the lockdown (40.4%) followed by unwanted pregnancy (32.4%) and sexual abuse (32.4%). Marital, educational, and employment status were significantly correlated with the reported experiences of the participants. Conclusion: Access to SRH information and services for Ugandan youth was restricted during the COVID-19 lockdown and leaving them vulnerable to various SRH risks and adverse outcomes. Lack of transportation, long distances to health facilities, and high cost of services were important limiting factors. The Government and other stakeholders should incorporate SRH among the priority services to be preserved during future outbreaks.

Strengthening Laboratory Diagnostic Capacity to Support Cancer Care in Uganda.

OBJECTIVES: 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. METHODS: A phased multistep approach was used to improve laboratory capacity, including staff training, additional staff recruitment, equipment overhaul, and optimization of the supply chain. RESULTS: 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. CONCLUSIONS: 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.

Outcomes of treatment with CHOP and EPOCH in patients with HIV associated NHL in a low resource setting.

BACKGROUND: The optimal chemotherapy regimen for treating HIV associated NHL in low resource settings is unknown. We conducted a retrospective study to describe survival rates, treatment response rates and adverse events in patients with HIV associated NHL treated with CHOP and dose adjusted-EPOCH regimens at the Uganda Cancer Institute. METHODS: A retrospective study of patients diagnosed with HIV and lymphoma and treated at the Uganda Cancer Institute from 2016 to 2018 was done. RESULTS: One hundred eight patients treated with CHOP and 12 patients treated with DA-EPOCH were analysed. Patients completing 6 or more cycles of chemotherapy were 51 (47%) in the CHOP group and 8 (67%) in the DA-EPOCH group. One year overall survival (OS) rate in patients treated with CHOP was 54.5% (95% CI, 42.8-64.8) and 80.2% (95% CI, 40.3-94.8) in those treated with DA-EPOCH. Factors associated with favourable survival were BMI 18.5-24.9 kg/m2, (p = 0.03) and completion of 6 or more cycles of chemotherapy, (p < 0.001). The overall response rate was 40% in the CHOP group and 59% in the DA-EPOCH group. Severe adverse events occurred in 19 (18%) patients in the CHOP group and 3 (25%) in the DA-EPOCH group; these were neutropenia (CHOP = 13, 12%; DA-EPOCH = 2, 17%), anaemia (CHOP = 12, 12%; DA-EPOCH = 1, 8%), thrombocytopenia (CHOP = 7, 6%; DA-EPOCH = 0), sepsis (CHOP = 1), treatment related death (DA-EPOCH = 1) and hepatic encephalopathy (CHOP = 1). CONCLUSION: Treatment of HIV associated NHL with curative intent using CHOP and infusional DA-EPOCH is feasible in low resource settings and associated with > 50% 1 year survival.

Aetiology of pulmonary symptoms in HIV-infected smear negative recurrent PTB suspects in Kampala, Uganda: a cross-sectional study.

INTRODUCTION: Previously treated TB patients with pulmonary symptoms are often considered recurrent TB suspects in the resource-limited settings, where investigations are limited to microscopy and chest x-ray. Category II anti-TB drugs may be inappropriate and may expose patients to pill burden, drug toxicities and drug-drug interactions. OBJECTIVE: To determine the causes of pulmonary symptoms in HIV-infected smear negative recurrent pulmonary tuberculosis suspects at Mulago Hospital, Kampala. METHODS: Between March 2008 and December 2011, induced sputum samples of 178 consented HIV-infected smear negative recurrent TB suspects in Kampala were subjected to MGIT and LJ cultures for mycobacteria at TB Reference Laboratory, Kampala. Processed sputum samples were also tested by PCR to detect 18S rRNA gene of P.jirovecii and cultured for other bacteria. RESULTS: Bacteria, M. tuberculosis and Pneumocystis jirovecii were detected in 27%, 18% and 6.7% of patients respectively and 53.4% of the specimens had no microorganisms. S. pneumoniae, M. catarrhalis and H. influenzae were 100% susceptible to chloramphenicol and erythromycin but co-trimoxazole resistant. CONCLUSION: At least 81.5% of participants had no microbiologically-confirmed TB. However our findings call for thorough investigation of HIV-infected smear negative recurrent TB suspects to guide cost effective treatment.

Clinical characteristics, treatment and outcome of childhood Burkitt's lymphoma at the Uganda Cancer Institute.

Burkitt's lymphoma (BL) is a major cause of death among Ugandan children. We studied clinical characteristics and outcomes of childhood BL over time at the Uganda Cancer Institute (UCI). A total of 1217 children (766 boys, 451 girls, mean age 6.69 years) diagnosed with BL between 1985 and 2005 were included. There were no significant changes in the proportion of boys and girls diagnosed, or in mean age at diagnosis. Facial tumor (n=945, 77.65%) and abdominal disease (n=842, 69.19%) were the most common presentations. The proportion of children presenting with hepatic mass, malignant pleocytosis, and advanced-stage (stage C and D) BL increased during the study period (P<0.01). A total of 1085 children out of 1206 (89.97%) received at least one cycle of chemotherapy, and 832 of 1099 (75.71%) demonstrated objective response (i.e. complete or partial remission). The most common symptoms at BL diagnosis were fever (n=621, 51.03%), anemia (n=593, 48.73%), and weight loss (n=588, 48.32%). Significant increases in the proportion of children with fever, and significant changes in the proportion of children with anemia, night sweats and severe infection were observed. HIV positivity was 3.87%, but no substantial differences in the proportion of HIV-positive children were observed. Mortality was not significantly different over time: it was similar in boys and girls, higher in older children (compared with younger ones), in those with advanced-stage BL, and HIV-positive children, but lower in children with facial tumors compared with other tumor presentations, and among those who received chemotherapy.
