This protocol applies to patients with cholangiocarcinoma confirmed as resectable (operable) on imaging and staging who have undergone — or are completing — curative-intent surgery.
Resectable disease on imaging and staging identifies the patient group for whom surgery offers a potential cure. Surgical resection is the only therapeutic option — other than liver transplantation in a small, highly selected subset — that can achieve curative outcomes in cholangiocarcinoma.
R0 resection, achieving complete removal with negative resection margins, is the only curative treatment available. Once surgery has been performed, the immediate clinical question is what structured post-surgical therapy should follow.
The preceding step was curative surgical resection at a high-volume centre — targeting a complete R0 resection with negative margins. This protocol defines the treatment approach that comes after surgical resection has been carried out.
