Background:
The prognostic relevance of a Japanese-like lymphadenectomy for gastric adenocarcinoma is Caucasian patients is not well establishes.
Methods:
Skeletonizing en-bloc gastrectomy (SEBG) (including removal of the stomach, excision of the potentially involved lymph nodes, and skeletonization of the main anatomic structures in the upper abdominal floor) was attempted in 216 consecutive patients with adenocarcinoma of the stomach. Gastrectomy was total in 143 patients, and subtotal in 72. One debilitated patient had a wedge resection of the gastric wall.
Results:
SEBG was performed in 160 patients (74%), whereas 56 patients (26%) had a palliative gastrectomy (PG) without lymph node dissection. The feasibility rate of SEBG was influenced significantly ( P < 0.001) by the depth of wall penetration, so that it dropped from 97% in T1 tumors to 91%, 65%, and 17% in those classified T2, T3, and T4, respectively. The 5-year survival rate, including postoperative mortality (0.9%) was 48% for the whole series, 66% after SEBG, and 0% after PG. The 5-year survival rate after SEBG was related significantly to the lymph node involvement (N0, 75% vs N+, 54%; P = 0.008) and to its magnitude (N+, <5 metastatic lymph nodes, 62% versus N+, > or =5 metastatic lymph nodes, 39%; P = 0.018). Considering the fact that 9 patients died of an unrelated cause before the postoperative term of 5 years, the cancer-related survival rate 5 years after SEBG was 71% in the whole group of 160 patients. This survival rate was 82% in patients with normal lymph nodes, versus 56% in those with metastatic nodes ( P < 0.001).
Conclusions:
SEBG was feasible in three-quarters of a po-pulation of Caucasian patients operated on for gastric adenocarcinoma. SEBG provided a chance for a longterm favorable outcome in three-quarters of patients with normal lymph nodes and in more than half of those with metastatic lymph nodes. These results are similar to those achieved after radical gastrectomy in Japanese patients with gastric adenocarcinoma. The prognostic relevance of a Japanese-like lymphadenectomy for gastric adenocarcinoma in Caucasian patients is not well established.
