Abstract
Background
The objective of this study was to clarify a survival benefit of D2 lymphadenectomy in patients with early gastric carcinoma (GC).
Methods
A retrospective study was conducted to examine the incidence of metastasis to level 2 lymph nodes, the causes of postoperative death, and the mode of recurrence in 1041 patients who head early GC and underwent D2 lymphadenectomy with curative intent.
Results
Postoperative mortality occurred in 129 (12,4%) of 1041 patients, 6 patients (.6%) died of surgical complications 108 (10.2%) died of diseases other than cancer, and 16 (1.5%) died of recurrence. Hematogenous metastasis was the major mode of recurrence (56.3% of recurrences). The incidence of metastasis to level 2 nodes was 2.5% (26 of 1041 patients, 18 of whom were alive). Thus, the estimated survival benefit of radical lymphadenectomy for patients with early GC was calculated to be 1.7% (18 of 1041 patients).
Conclusions
D2 lymphadenectomy in patients with early GC had little survival benefit because (1) metastasis to level 2 nodes was rare, (2) most causes of death were not related to the tumor, and (3) more than half the recurrences were hematogenous. Use of radical lymphadenectomy for early GC should be limited.
