Esophageal cancer in Iran.
Esophageal cancer is among the 10 most frequent cancers in the world. Iran is one of the known areas with a high incidence of esophageal cancer. Most of the patients in Iran have been reported from the north and northeast regions of the country. In one survey by the Iran Cancer Institute, 9% of all cancers and 27% of gastrointestinal cancers were esophageal carcinoma. The male to female ratio was 1.7/1. The distal portion of the esophagus is involved more often than other parts. Consumption of wheat flour, exposure to residues from opium pipes, drinking hot tea, and chewing nass (a mixture of tobacco, lime, ash, and other ingredients) are the suspect etiologic agents for esophageal cancer in Iran. Dysphagia, weight loss, anorexia, abdominal pain, and odynophagia are the common symptoms and signs of Iranian patients with esophageal cancer. For clinical staging, chest computed tomographic scanning is performed. Adenocarcinoma of the esophagus is not as common in Iran as in western countries. Public education, nutritional support, and eradication of opium addiction may decrease the morbidity and mortality that result from esophageal cancer. Surgery has traditionally been the mainstay of esophageal cancer treatment in Iran. Radiotherapy is mainly used postoperatively. The usual combination chemotherapy regimen is cisplatin plus flurouracil (5-Fu). Semin Oncol 28:153-157.
