A retrospective study of carcinomas of the hypopharynx was conducted to examine the epidemiological and clinical features of this cancer in Senegal. An analysis of 66 cases showed a very particular distribution in Senegal with more female (57.6%) than male cases. Average age at diagnosis was 33 years. Advanced cancer (T3-T4) was noted in 65% of the cases, but the first physical examination noted the absence of cervical nodes in 53.6% of the cases. Location at the piriform sinus was observed in 41% of the cases, followed by the posterior wall of the hypopharynx (25.7%). Chronic anemia with iron deficiency was seen in 30% of the cases, probably an important etiological factor of the cancer in Senegal. This point would be the goal of a future prospective study.
对下咽癌进行了一项回顾性研究，以调查塞内加尔这种癌症的流行病学和临床特征。对66例病例的分析显示，在塞内加尔该病分布非常特殊，女性病例（57.6%）多于男性病例。诊断时的平均年龄为33岁。65%的病例为晚期癌症（T3-T4），但首次体格检查发现53.6%的病例无颈部淋巴结。41%的病例病变位于梨状窦，其次是下咽后壁（25.7%）。30%的病例存在缺铁性慢性贫血，这可能是塞内加尔该癌症的一个重要病因。这一点将是未来前瞻性研究的目标。
