Background Lung cancer is a leading cause of cancer-related deaths in Uganda. In this study, we aimed to describe the baseline characteristics and survival of patients with lung cancer at the Uganda Cancer Institute (UCI). Methods We retrospectively reviewed medical records of all patients with a histological diagnosis of lung cancer registered at UCI between January 2008 and August 2018. Data on demographic, clinical, and treatment characteristics, and vital status were abstracted and analyzed. Patients with undocumented vital status on the medical records were contacted through phone calls. We determined survival as time from histological diagnosis to death. The Kaplan-Meier survival analysis was performed to estimate the median survival time and the 5-year overall survival rate. Results Of the 207 patients enrolled, 56.5% (n = 117) were female, median age was 60 years (range: 20–94), 78.7% (n = 163) were never-smokers and 18 (8.7%) were living with HIV. Presumptive anti-tuberculosis treatment was given to 23.2% (n = 48). Majority had non-small cell lung cancer (96.6%, n = 200) with 74.5% (n = 149) adenocarcinoma and 19% (n = 38) squamous cell carcinoma. All had advanced (stage III or IV) disease with 96.1% (n = 199) in stage IV. Chemotherapy (44.9%, n = 93) and biological therapy (34.8%, n = 72) were the commonest treatments used. Overall survival at 6 months, 1-, 2- and 5-years was 41.7, 29.7, 11.8, and 1.7%, respectively. The median survival time of 4.4 months was not statistically significantly different between participants with NSCLC or SCLC (4.5 versus 3.9 months, p = .335). Conclusion In Uganda, adenocarcinoma is the predominant histologic subtype of lung cancer and patients are predominantly females, and non-smokers. Patients present late with advanced disease and poor overall survival. Public awareness should be heightened to facilitate early detection and improve outcomes.
Onchocerciasis is known to cause skin lesions and blindness, but there is also epidemiological evidence that onchocerciasis is associated with epilepsy, including nodding syndrome. We carried out ocular exams in persons with epilepsy in Mahenge, an onchocerciasis endemic area with a high prevalence of epilepsy in Tanzania. We recruited 278 consecutive persons with epilepsy attending the epilepsy clinic at Mahenge hospital and satellite clinics in rural villages. They underwent a general physical and a detailed ocular examination and were tested for onchocerciasis Ov16 IgG4 antibodies. Glaucoma was defined by a raised intraocular pressure above 21 mmHg with evidence of typical glaucomatous disc changes in one or both eyes. Among the 278 participants, median age 27 (IQR 21–38) years, 55.4% were female; 151/210 (71.9%) (95% CI: 65.3–77.9) were Ov16 positive. The most frequent ophthalmic lesions were glaucoma (33.1%), vitreous opacities (6.5%) and cataracts (2.9%). In multivariate analysis, glaucoma (adjusted IRR = 1.46; 95% CI: 1.24–1.70) and age (adjusted IRR = 1.01; 95% CI: 1.01–1.02) were significantly associated with onchocerciasis. In conclusion, a high prevalence of glaucoma was observed among Ov16 positive persons with epilepsy. Persons with epilepsy with O. volvulus infection should undergo screening for glaucoma to prevent one of the causes of preventable blindness.

The median survival time was 4.4 months and was not different between NSCLC and SCLC (4.5 vs. 3.9 months respectively, p=.335). Conclusion: In Uganda, adenocarcinoma is the predominant histologic subtype of lung cancer predominantly occurring in females and non-smokers. Patients present late with advanced disease and poor overall survival. Public awareness should be heightened to facilitate early screening and improve outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
