BACKGROUND: In the literature, the 5 year survival rates for incidental gallbladder carcinoma (IGBC) show large variations in the different T-stages because the lymph node status often is not addressed. Most early-stage carcinomas are identified by laparoscopy as IGBC, and radical re-resection is needed. Staging is impossible without lymph node dissection, so comparison between various survival rates is impossible. This study aimed to determine the influence of lymph node status on the survival of patients with stages T1 to T3 IGBC. METHODS: For data analysis, the German Registry was used. RESULTS: In this study, 709 patients with IGBC were analyzed. The re-resected nodal-negative patients had a significant survival advantage over the re-resected nodal-positive patients. The 5 year survival rate for the patients with nodal-negative re-resected T1 carcinomas was 75%. The re-resected T2 and T3 nodal-negative patients had significantly better survival than the corresponding nodal-positive patients. The influence that the radicalness of the different liver resection techniques had on these results was excluded. 53 patients without radical resection had a known nodal-positive status. Nodal-positive patients with radical re-resection always show a better survival rate than nodal-positive patients without radical re-resection, stage for stage. CONCLUSIONS: Nodal-positive status is a significant negative prognostic factor in T1 to T3 IGBC. Patients with radical re-resection show a better survival rate than those without it. Lymph node dissection is to be highly recommended up to stage T1b. In the case of T2 carcinomas, lymph node dissection of the hepatoduodenal ligament seems to be the minimum volume of lymph node dissection required, but more radical procedures could be beneficial for tumors infiltrating the serosa or beyond.
