J Cancer Res Ther. Apr-Jun 2011;7(2):135-7. doi: 10.4103/0973-1482.82923.


Background: Locating at southern margin of Caspian sea and Asian esophagus cancer cordon Golestan state is one of the most common sites of this cancer.

Objective: This study designed to evaluate the 5-years survival rate of esophagus cancer.

Materials and methods: 55 patients with esophagus cancer diagnosed by pathologic examination, age, gender, type of tumor, clinical manifestation on the time of tumor metastases, treatment and patient survival time studied. The collecting data were analyzed by SPSS 11.5, and life table and Kaplan Meier methods were applied.

Results: 55 patients studied included 11 females and 44 males respectively with average survival life time of 12.8 months for the 5-year survival rate for patients diagnosed at early stage was 0.025, patients with systemic symptoms such as weight loss was 0.00. Far metastases adverse effect on highest survivals was observed among patients who underwent surgery; the survival rate for such patients was about 0.014.

Conclusions: Esophageal cancer is high in southern margin of Caspian Sea, it is suggested to design studies to find the probable risk factors and the screening tests for on-time diagnosis.
