Inclusion of Comorbidity in Cancer Statistics​​


"In clinical practice, the prognostic influences of age and comorbidity are well recognized, and these influences usually receive careful consideration during the diverse decisions of clinical judgment. In statistical studies, however, the effects of comorbidity are generally ignored."
         Alvan R. Feinstein MD, 1974


Comorbidity Coding Course​

Patients with cancer often have other diseases, illnesses, or conditions in addition to their index cancer. These ot​her conditions are generally referred to as comorbidities. Although not a feature of the cancer itself, comorbidity is an important attribute of the patient. Survival rates are lower for patients with a greater number and severity of comorbid conditions. Comorbidity also has direct impact on the care of patients, selection of initial treatment, and evaluation of treatment effectiveness. When reporting statistical survival data, hospital-based and national cancer registries do not routinely take into account these coexisting medical ailments. ​​​
