Selective Curative Approaches for Thoracic Esophageal Cancer
Keywords:
Esophageal carcinoma, three-phase esophagectomy, Ivor Lewis operationAbstract
Objective: To determine the survival probability of patients with carcinoma of the esophagus whounderwent en bloc esophagectomy and to compare two en-bloc surgical approaches.
Materials and Methods: Between October 2005 and September 2008, 81 patients with the diagnosis of
esophageal carcinoma were treated at Suratthani Hospital. Esophagectomy was performed on 64 (79%) of these
patients, 18 of whom had upper or mid esophageal carcinoma and underwent three-phase esophagectomy, while
46 had low esophageal carcinoma and underwent the Ivor Lewis operation. We analyzed the location and
histology of the tumor, the number and level of lymph nodes, operative morbidity and mortality, and their
influence on survival probabilities.
Result: The overall survival probability at 5 years was 19 %. The 5-year survival probabilities for the
three-phase esophagectomy (upper and mid esophageal cancer) and the Ivor Lewis operation (low esophageal
cancer) were 4 % and 25%, respectively, which were significantly different. There was no left cervical lymph
node metastasis in patients who underwent the Ivor Lewis operation. The most common complication was
wound infection. Most patients died from sepsis or myocardial infarction. The overall operative (hospital)
mortality rate was 8 %.
Conclusion: Location of the tumor should strongly influence the type of surgery performed for
esophageal carcinoma, and seemed to significantly affect the survival probabilities in the present study.
