Prognostication in oncology.

Prognostication involves formulation and communication about the expected course of the disease and is unique in surgical oncology because of the need to incorporate patient, procedural, and cancer-related factors. Several tools and techniques are available to assist physicians in formulating prognosis on the basis of these factors. Use of established communication techniques are effective in discussing prognosis. In situations with prognostic uncertainty, use of the best case/worst case/most likely case or time-limited trial of therapy can be helpful.
