If medical oncologist or palliative care physician agrees to take part in this study, participant will be asked to complete a survey. The referring medical oncologist and palliative care physician will complete the same questionnaire with regards to their last encounter with the patient. The survey contains questions about participant's gender, years of clinical experience, participant's clinical prediction of survival for the patient (temporal question, surprise question, and probabilistic question), patient's cancer treatment plan, and associated factors to determine survival estimation and decision-making. The survey should take about 5 minutes to complete.
