Background:
Although the treatment and diagnostic regimens of gall bladder carcinoma and extrahepatic bile duct cancer have improved over the past years, the outcome and overall survival as prognostic values still remain poor. Early tumor stages of gall bladder carcinoma are the only exception.
Objective:
This article focuses on the latest surgical therapy approaches including neoadjuvant, adjuvant and palliative therapy regimens.
Results:
Neoadjuvant treatment concepts have so far been insufficiently evaluated and can therefore only be recommended within the framework of studies. In patients with primary resectable tumors there are so far no indications for improved results after neoadjuvant therapy. Radical R0 resection still remains the only curative treatment option; however, an advanced and inoperable stage is often already present at the time of diagnosis There are no uniform adjuvant treatment concepts and no standards evaluated by studies. Due to the currently available data, adjuvant radiochemotherapy and chemotherapy can also only be recommended within or as part of clinical trials. Palliative chemotherapy should only be used in advanced tumor stages and depending on the condition of the patient.
Conclusion:
To sustainably improve treatment strategies for advanced gall bladder carcinoma and extrahepatic bile duct cancer, uniform adjuvant as well as neoadjuvant therapy regimens need to be developed after evaluation in prospective randomized trials. This is the only way to improve the still poor prognosis of these tumor entities.
