Oesophageal cancer, the eighth most frequent cancer in the world occurs as two main subtypes, squamous cell carcinoma (more prevalent in developing countries) and adenocarcinoma (more common in developed countries). Certain populations of central, eastern, and southern Africa display very high frequencies of oesophageal squamous cell carcinoma, presenting a serious health burden to the continent. Most patients are diagnosed at a late stage because of the asymptomatic development of the disease, with associated poor prognosis. A better understanding of the aetiological agents and molecular mechanisms involved in the development of oesophageal squamous cell carcinoma may offer opportunities to reduce exposure to environmental risk factors and also allow early diagnosis or predict response to therapy. Epidemiologic studies have identified smoking, alcohol consumption, diets poor in fresh fruit and vegetables, consumption of foods contaminated with Fusarium verticillioides, and HPV infection as risk factors associated with the development of this disease in Africa. Although we have an incomplete understanding of the molecular events involved in the development of oesophageal squamous cell carcinoma, advances have been made that suggest lines of future exploration. South African patients with oesophageal squamous cell carcinoma display a lower incidence of point mutations in the p53 gene than described elsewhere, suggesting that the profile of aetiological agents may be different than described for other high-risk areas for oesophageal cancer. Recent studies suggest that RARbeta and COX II is frequently downregulated and upregulated, respectively, in oesophageal squamous cell carcinomas. These results suggest potential therapeutic opportunities that can be exploited to combat the high incidence of this disease in Africa.
