Should I only enter chemoradiotherapy data for patients who have also undergone surgery?

No – we are interested in the chemoradiotherapy received by all patients, regardless of whether they undergo surgery. Where a patient has undergone surgery, data should be entered into the pre- and post-operative data fields. Where a patient has not undergone surgery, data should only be entered into the pre-operative data field. If the patient has palliative chemotherapy only and no surgery enter ‘03’ in ‘PlannedCancerTreatmentType’.
