Overview
to study role of chemotherapy treatment for gall bladder cancer before surgery as compared to surgery directly
Description
Gallbladder cancer is a highly aggressive disease with a late presentation and poor prognosis. Complete surgical excision remains the only potentially curative treatment for early-stage gallbladder cancer.
The use and benefit of chemotherapy in gallbladder cancer before surgery , that is , in the neoadjuvant setting, is not well studied and, to our knowledge, neoadjuvant chemotherapy has not been evaluated in any randomized clinical trial.
Neoadjuvant chemotherapy aims to achieve tumor downstaging, increase the radical surgical resection rate, reduce metastases. This study will compare the effectiveness of chemotherapy before surgery in locally advanced gall bladder cancer versus upfront surgery with respect to survival and completeness of resection of disease.
Eligibility
Inclusion Criteria:
