Comparative analyses between radically re-resected incidental gallbladder carcinoma and primary radically resected gallbladder carcinoma: a single-center experience in China.

PURPOSES: The current study was performed to comparatively evaluate the similarities and differences between cases with radically re-resected incidental gallbladder carcinoma (RRIGBC) and those with primary radically resected gallbladder carcinoma (PRGBC).

METHODS

Comparative analysis between patients with RRIGBC and those with PRGBC were performed in terms of clinic-pathological features and long-terms survival.

RESULTS

A total of 330 surgically treated GBC patients with 110 patients with IGBC were identified. PRGBCs were generally in a more advanced tumor stage, sharing more aggressive tumor biological features and worse prognosis than those with RRIGBC. Subgroup analyses indicated a comparable prognosis among T1-2 patients between RRIGBC and PRGBC groups. However, among T3-4 patients, patients in the PRGBC group shared a much worse prognosis. Moreover, IGBC itself can be regarded as a prognostic factor but cannot be regarded as an independent prognostic factor. It is the tumor stage which really determined the overall prognosis.

CONCLUSION

Patients with RRIGBC were generally in a much earlier tumor stage and shared a much better prognosis than those with PRGBC. IGBC itself can be regarded as a prognostic factor but cannot be regarded as the independent prognostic factors. It is the tumor stage which really determine the overall prognosis.
