Head and neck cancer constitutes one of the commonest malignancies in Yemen. There may be a role for the use of Shamma and Zarda and Khat for the increase of HNC in Yemen. This study was conducted retrospectively with an overall aim to describe the pattern of head and neck cancers among Yemeni patients attending the Oncology Department of Al-Gamhouria Teaching Hospital, Aden, for the period from Jan. 2001 to Dec. 2004. The study included 183 patients with head and neck cancers (Lymphoma and thyroid were excluded), 134 were males (73.2%) and 49 were females (26.8%) , with male to female ratio of 2.7:1. The mean age was 51.3 +/- 14.9 years (range: 3 - 82 years). Statistically, there is significant difference between the mean age of male (49.5 +/- 15.1 years) and female (45.4 +/- 16.3 years) patients with head and neck cancers [t= 2.1, p: 0.03]. The common types of head and neck cancers in this study are cancers of the oral cavity (31.7%), followed by pharyngeal (22.9%) and laryngeal (19.1%). In relation to sex, there is a significant statistical relationship between certain head and neck cancers and sex (p: 0.0000). In males, the common cancers are oral cavity cancers (22.7%), laryngeal (22.1%) and pharyngeal cancers (20.8%). The common histopathological type of head and neck cancers in this study is the well differentiated squamous cell carcinoma (70.5%). This study concluded that head and neck cancers are among the common health problems affecting Yemeni patients and recommended further wide national studies to determine the real incidence and the risk factors associated with such cancer.
头颈癌是也门最常见的恶性肿瘤之一。在也门，嚼咔特（Shamma）、扎尔达（Zarda）和巧茶（Khat）的使用可能与头颈癌发病率的增加有关。本研究采用回顾性研究方法，总体目标是描述2001年1月至2004年12月期间在亚丁的盖姆胡里亚教学医院肿瘤科就诊的也门患者的头颈癌发病模式。该研究纳入了183名头颈癌患者（淋巴瘤和甲状腺癌患者被排除），其中男性134例（73.2%），女性49例（26.8%），男女比例为2.7:1。平均年龄为51.3±14.9岁（范围：3 - 82岁）。统计学上，头颈癌男性患者（49.5±15.1岁）和女性患者（45.4±16.3岁）的平均年龄存在显著差异[t = 2.1，p = 0.03]。本研究中头颈癌的常见类型为口腔癌（31.7%），其次是咽癌（22.9%）和喉癌（19.1%）。在性别方面，某些头颈癌与性别之间存在显著的统计学关系（p = 0.0000）。在男性中，常见的癌症是口腔癌（22.7%）、喉癌（22.1%）和咽癌（20.8%）。本研究中头颈癌常见的组织病理学类型是高分化鳞状细胞癌（70.5%）。本研究得出结论，头颈癌是影响也门患者健康的常见问题之一，并建议开展进一步广泛的全国性研究，以确定此类癌症的实际发病率和相关危险因素。
