ABSTRACT
Three-field lymphadenectomy for esophageal cancer remains controversial. The high prevalence of cervical lymph node involvement is the basis of cervical lymphadenectomy. Studies of recurrence patterns after esophagectomy, however, indicate that clinically relevant cervical nodal recurrence is uncommon, and that the incidence of such recurrence is similar to that of two-field lymphadenectomy. Moreover, a convincing survival benefit cannot be proven for the more extended lymphadenectomy. The emphasis of three-field lymphadenectomy has shifted to lymphadenectomy of the superior mediastinum and along the recurrent laryngeal nerve chains. Radical dissection of these areas may improve local disease control; the price to pay is increased postoperative morbidity and impaired long-term quality of life. Furthermore, the selection of appropriate patients for extended lymphadenectomy is difficult. Formal three-field lymphadenectomy seems unnecessary, but the controversy of the optimal extent of lymphadenectomy and its impact on survival remains unanswered.
