Bladder cancer: a retrospective audit at a single radiation oncology unit of an academic hospital in Johannesburg, South Africa.
Background: Bladder cancer (BCa) is one of the most common urological cancers and remains a leading cause of cancer-related mortality worldwide. Bladder cancer is associated with a range of risk factors, with smoking being one of the most significant contributors. In addition to smoking, exposure to certain chemicals, particularly aromatic amines found in industries such as dye, rubber, leather, and textiles, also increases the risk of bladder cancer. In low-and-middle countries with lower Human Development Index (HDI), data on the underlying causes, incident rate, modes of presentation, treatment, and prognosis of bladder cancer remains unclear and often appear to be inadequate. This study aimed to assess the prevalence, mode of presentation, treatment, and risk factors associated with bladder cancer in Johannesburg, South Africa. By examining these factors, the study seeks to identify possible patterns or predisposing factors that contribute to the development and progression of bladder cancer, which could generate insights that could help to reduce the significant morbidity and mortality associated with this cancer.
Methods: This retrospective study analyzed secondary data from 115 patients who were treated in the radiation oncology unit of an academic hospital between January 2010 and December 2020. By reviewing the medical records of these patients, the study aimed to gather comprehensive information on the prevalence of bladder cancer, modes of presentation, treatment approaches, and associated risk factors. Bladder cancer in this study was assessed using a comprehensive analysis of patient data on demographics, risk factors, clinicopathological aspects, and the specific therapies received. A comparison of patients with squamous cell carcinoma (SCC) and transitional cell carcinoma (TCC) of the bladder was conducted as part of this study. This comparison aimed to explore differences in demographic profiles, risk factors, clinicopathological characteristics, and treatment outcomes between these two histological subtypes.
Results: A total of 115 patients presenting with bladder cancer symptoms were referred to the academic hospital for evaluation and treatment. The incidence rate of bladder cancer was highest among patients with a mean age of 60.7 ± 14.9. Males constituted 60.9% of the cases, resulting in a male-to-female ratio of 1.6:1. The most common risk factors associated with bladder cancer complications included smoking, being male, black ethnicity and increasing age. Transitional cell carcinoma remained the most prevalent histological subtype at the academic hospital, compared to squamous cell carcinoma (SCC). Patients with transitional cell carcinoma (TCC) were more likely to be older (odds ratio (OR): 1.03, 95% Confidence Interval (CI): 1.01-1.06, p = 0.029), male (OR: 2.60, 95% CI:1.10-6.04, p = 0.030). The study also found that most of the TCC cases were among black patients, though white patients were four times more likely to present with TCC compared to SCC (OR:4.22, 95% CI: 1.43-12.48, p = 0.009).
Conclusion: Bladder cancer is still widespread in LMICs, with lower HDI, with elderly males being at risk. To aggressively prevent mortality and morbidity from bladder cancer, bladder cancer health awareness must be maintained to improving prevention, as well as early detection, management and comprehensive patient care and health services for bladder cancer patients. These findings highlight the importance of targeted screening and prevention strategies for high-risk groups, particularly older males with a history of smoking.
期刊介绍:
As the official publication of the National Cancer Institute, Cairo University, the Journal of the Egyptian National Cancer Institute (JENCI) is an open access peer-reviewed journal that publishes on the latest innovations in oncology and thereby, providing academics and clinicians a leading research platform. JENCI welcomes submissions pertaining to all fields of basic, applied and clinical cancer research. Main topics of interest include: local and systemic anticancer therapy (with specific interest on applied cancer research from developing countries); experimental oncology; early cancer detection; randomized trials (including negatives ones); and key emerging fields of personalized medicine, such as molecular pathology, bioinformatics, and biotechnologies.
