Cancer Survival Prediction

Post-Operative Radiation

Oral Cavity Squamous Cell Cancer


After a patient has surgery for oral cavity cancer, 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.

Predicted Survival Calculator: Oral Cavity Cancer

Predicted locoregional recurrence-free survival:

This web calculator is based on a lognormal survival model built from a database of oral cavity cancer patients from the Memorial Sloan-Kettering Cancer Center and the Hospital do Cancer AC Camargo, Sao Paulo, Brazil. The model was externally validated on a set of patients from the Princess Margaret Hospital. For more information, see Wang SJ, Patel SG, Shah JP, Kowalski LP, Kalpathy-Cramer J, Thomas CR, Gross ND.
