Oesophageal carcinoma constituted 2.39% of all malignancies, and 17.11% of gastrointestinal tract malignancies, over a period of 12 years, in Sir Sunder Lal Hospital population in Varanasi. The highest frequency occurred in the sixth decade. The male:female ratio was 2.2:1, this ratio tended to diminish with age. Out of 202 cases the middle third of the oesophagus was involved in 104, the lower third in 72 and the upper third in 26 cases. Although squamous cell carcinoma was by far the most frequent histologic type (193 cases), genuine primary oesophageal adenocarcinoma did occur in 3, and the tumour was completely anaplastic in the remaining 6 cases. The prognostic bearing of certain morphologic features has been discussed. Oesophageal carcinoma is one of the most frequent malignancies of the gastrointestinal tract and a common tumour in elderly Indian men and women.
在瓦拉纳西的苏达·拉尔爵士医院，12年间食管癌占所有恶性肿瘤的2.39%，占胃肠道恶性肿瘤的17.11%。最高发病频率出现在第六个十年。男女比例为2.2:1，该比例随年龄增长而趋于下降。在202例病例中，食管中段受累104例，下段受累72例，上段受累26例。虽然鳞状细胞癌是迄今为止最常见的组织学类型（193例），但真正的原发性食管腺癌有3例，其余6例肿瘤完全未分化。文中讨论了某些形态学特征对预后的影响。食管癌是胃肠道最常见的恶性肿瘤之一，也是印度老年男性和女性的常见肿瘤。
