Cancer Survival Prediction

Post-Operative Radiation

Extrahepatic Cholangiocarcinoma


After a patient has surgery for extrahepatic cholangiocarcinoma, post-operative radiotherapy may be recommended for certain patients who may be at higher risk for recurrence. This calculator will estimate the additional benefit from radiotherapy, based on specific risk factors for a given patient.

Enter the patient details below to calculate the estimated survival based on different treatment options.
